This invention relates to a means for protecting from decay and attack by insects, etc., of the portion of poles, posts, etc., which is adjacent the surface of the ground.
It is well known that poles or posts which have one end placed in the ground are subject to decay more at those portions of the posts at and im mediately adjacent to the surface of the ground both above and below the suriace'than at any other point. It has been recognized that if this portion of the pole or post is protected from decay and insects that the life of the pole will he very materially increased, and furthermore that the dangerous condition of having "the pole rotten or decayed just below the surface of the ground will be avoided.
In the past there has been developed certain means for encasing this portion of poles for the purpose of protecting the same. Also, sleeves of metal or the like have been placed around this portion of poles, and the intermediate space between the sleeve and the pole filled with a sterilizing material to protect this part of poles from the action of the insects.
These protectors in the past havebeen made either of metal which as is well known will in turn corrode and leave the pole substantially without protection, or have been made of burned or dried clay which is not in itself waterproof, and which does not therefore offer the protection necessary, 7
In the case of the protectors previously made of clay, these have for the most part been formed of two or more pieces each extending part way around the pole, the pieces being of different diameters whereby they may be telescoped within each other to form a complete coverage around the pole.
One of the objects of this invention is to provide a means of protecting poles, which means may be easily and quickly attached to the poles,
and which will also be adjustable to fit around the poles of various diameters. It is an object of this invention that this protective means shall be relatively easy and inexpensive to manufacture, shall be impervious to both moisture and decayand hence practically everlasting, and shall be provided with means for preventing it from being improperly spaced from the post or actually in contact with the post along one side thereof.
Other objects and advantages of this invention will become apparent from the following -de- 'scription taken with the accompanying drawing, it being clearly understood that the same are by way of illustration and example only and are not to be taken as in any way limiting the spirit or scope of this invention. The spirit and scope of this invention is to be limited only by the prior art taken inconnection with the accompanying 5 claims. a
Referring now more particularly to the drawing in which like numerals indicate corresponding parts throughout:- I
Figure l is a View illustrating the application of the device of this invention to a post or pole.
Figure 2 is an end view of the device illustrated in Figure 1.
Figure 3 is'an end view of the device shown in Figure 2 during a step in the manufacture thereof.
Figure 4 is a view illustrating a slightly modified form of this invention.
Figure 5 is a View similar to Figure 3 but illustrating the device of Figure 4 during the corresspending step' in the manufacture thereof.
Figure 6 is a view illustrating another slight modification.
Figure '7 is a view partly in section illustrating the shape of the upper portion of the wall of each of the three modifications.
Referring now to Figure 1, the pole is illustrated as having been placed in the ground 2 in the ordinary manner, but instead of having the earth entirely filled in about the pole up to the normal surface 3 of the ground a protective member generally indicated by the numeral 4 has been placed about the pole so as to extend a short distance both above and below the surface 3 of the ground. As illustrated, this protective member 4 is preferably so formed as to be spaced slightlyfrom the pole on all sides, so that this intermediate space may be filled with some impervious protective substance which will absolutely protect the post from decay and attack by insects during all conceivable conditions., In this instance, this space is shown as having been filled with asphalt or the like 5, the surface of the asphalt extending slightly above thetop of the member 4 at points adjacent the pole, and sloping therefrom downwardly to the top edge of the member 4.
Referring now to Figures 2 and 3 of the drawing, it will be seen that in this form the protective device illustrated consists of a pair of cooperating complementary sections 6 and I each forming substantially half a circle, and together forming a substantially circular member for surrounding the pole. As shown, the member 6 is formed with one of its terminal edges 8 of ordinary Cir straight formation, but adjacent its opposite edge it is formed with an outwardly extending portion 9 carrying an ofiset portion I ii at the opposite edge of which is an inwardly directed portion I I, these three last named wall portions cooperating to form a channel or hook-shaped terminal edge on the member 6. With reference to the member "i, this member is provided adjacent the edge 8 of the member 6 with an outwardly extending portion I2 and an offset portion I3 forming a notch adapted to receive the terminal edge portion 8. At its opposite edge, this member 1 is provided with a short outwardly extending por-' tion i4 adapted to be engaged between the portions 9 and II of the member 6 and lie against the offset portion 8 ll thereof, thus forming a substantially interlocking connection between these parts.
Now it will readily be seen that if the pole be a small one,-the portion Id of the member 'I may lieolosely adjacent the outwardly extending portion 9 thus making the protective member as small as possible in diameter. If on the other hand the pole be a larger one,.the outwardly extending portion l4 may lie further from the outwardly extending portion 9 and closer to the portion l I thus increasing the size of the circle within the protective member. If it berdesired to make the space within this member still larger to accommodate a somewhat larger pole, the end 8 may be'partly removed from the notch formed by the projections I2 and I3 tov accomplish this purpose. It will be seen however that under all of these conditions the terminal portions of the two members 5 and I will alwaysinterlock to form joints through which there will be substantially no leakage when the asphalt material 5 is'poured. in place. It is to be understood of course that if any other means besides the weight of the earth 2 is required to hold the parts 6 and I together, that suitable means may be provided for that purpose.
With further reference toiligure 2, it will'be seen that the upper edges of both members 6 and F are chamfered at l5 substantially all along the inner wall thereof to provide, a. funnel-shaped surface to enable the asphalt material to be more readily poured into place and retained therein. Furthermore, if due to some irregularity in the pole construction or otherwise by accident the protective members should come in contact with one side of the post, the asphalt material would fill in along the chamfered portionof the edge and form a seal to prevent water and insectsfrom getting at that portion of the pole even though the asphalt itself did not reach all portions of the pole. This chamfering of the upper edge of the protecting member along the inner wall thereof is more, clearly illustrated in Figure 7, the inner wall of the protective member being designated at It in this figure. I
For the purpose of affixing and the spacing of the members 5 and 1 from the pole I in the proper degree, the inner walls of these members are provided with bulgesor projections "adapted to contact with the sides of the pole. 7 These bulges I? are so spaced from each other that when the members 6 and l are placed together as shown to form a circle, these three members will be spaced about the interior thereof by substantially equal distances. 1 1 r Referring now to Figure 3, it will be noted that the members 6 and I of the, form illustrated in Figure 2 have been so designed and proportioned that in the manufacture thereof they may be formed from one hollow piece ofmateriale; These sections are preferably formed from salt glazed vitrified material such as is ordinarily used for sewer pipes and other similar purposes. As is clearly shown here the distance between the inwardly extending portion I I and the terminal end portion 8 is exactly the same as the distance between the outwardly extending portion I4 and the offset terminal end portion l3. In the process of manufacture, the two members 6, and I are made integral with each other with the portions I I and M in contact with each other and the portions 8 and I3 in contact with each'other. After the member has been formed as illustrated in Figure 3, it is scored at I8 and I9 so that when the manufacture has been completed it may be tapped lightly and broken apart along the scoring lines. This clearly forms the separate members 6 and 'I as illustrated in Figure 2. The chamfering |5 may be done while the parts are in integral form if so desired.
Referring now more particularly to Figures 4 and 5, it will" be seen that the form of Figure 4 consistsv of two members 20 and 2| which like the members 8 and 'I are each substantially semicylindrical and have portions at their edges adapted to interengage with each other. When placed together as shown in Figure 4 these members form a substantially cylindrical member of approximately uniform diameter throughout in the same manner as the members 6 and 'I of Figure 2. In thisvform also, the top edges of the members 25 and 2|, are chamfered at 22 in'the same manner as the top edges of the membersi and l are chamfered at l5. These members 2| and 22 are also provided with bulges or projections 23 which are identical with the bulges l1 and for the same purpose.
Instead of having their terniinalredge portions formed in the manner illustrated in Figures 2 and 3 however each of the members 20 and 2| has one of its terminal edge portions formedwith the outer half thereof projecting beyond the inner half to form a projecting tongue '24 and a notched portion 25. The other terminal edge of each portion is formed with its inner half projecting beyond the outer half to form a tongue 26 and a notched portion 21. It will be seen that when the two members 20 and 2| are placed together in the manner illustrated in Figure 4 the tongues 26 will engage in the notches 25 and the tongues 24 will likewise engage in the notches 21 thus forming a continuous circular member with the joints between the two portions 20 and 2! formed of overlapping parts so as to allow the parts to be slid apart or together to accommodate the varying sizes of poles, and at the same time provide a joint from which the asphalt Qor like material which is to be placed inside will not leak.
The method of manufacturing the form illustrated in Figure 4 is shownin Figure 5, the two parts 26 and 2| being formed in one continuous hollow piece with the projection 24 and the projection 26 integrally joined with each other. It will be seen that these parts 124 and 26 may be brought together by merely reversing one of the portions 2| and-placing theparts together.
It will be seen that this continuous member from' which the members 20 :and 2| are subsequently formed is necessarily of a somewhatoval shape in order to accommodate for the extra size due to the tongues orprojections 24 and;26 coming'together instead of fitting in the notches in the opposite portion as illustrated in Figure 4. In order to provide for separating these portions from each other after the process of manufacture is completed, the composite member illustrated in Figure 5 is scored at 28 and 29 so that the two parts may be broken from each other by slightly tapping them in the same manner as previously described in connection with Figure 3.
Referring now to Figure 6 there is shown a still further modification in which the two members 30 and 3| are formed in the manner similar to those illustrated in Figures 4 and 5, the inner edges being chamfered at 32 and the inner walls being provided with projections 33 corresponding with the similar members previously described. In order to provide for breaking these portions apart so that they may be placed around the pole, the complete member in the form in which it is manufactured is notched deeply at diagonally opposite portions 34 and 35 so that it may be broken apart by tapping as previously described. In addition to the notches or sco'rings 34 and 35, this member is also provided with additional scorings which are not so great in depth at diagonal- 1y opposite points 36 and 31. The purpose of these additional scorings is to allow the portions between the notches 34 and 3B and between the notches 35 and 31 to be broken off and done away with in case it is desired to place the protective structure around a pole which is of smaller diameter than that for which the member was originally intended. It will thus be seen that a member of this sort is adjustable to at least three definite and distinct sizes, and it is clearly apparent that further notches or scorings might be employed for the purpose of providing still further adjustment.
From the above, it will be seen that means has been provided for carrying out all of the objects of this invention, and that the resulting structure is easy and simple to manufacture, is adjustable to poles of various sizes, is formed so as to more easily enable the asphalt or other filler material to be forced between the protective device and the pole, and is provided with means for properly spacing the same from the pole. In addition means has been provided for joining together the two parts or sections of a protective structure such as described, the joints between those two parts being formed so as to be both adjustable and at the same time to prevent leakage of the filler material through said joints.
What we claim is:-
1. An article of manufacture comprising a hollow substantially cylindrical glazed vitrified member of substantially the proper size to fit a given pole, said member having deep scores on opposite sides thereof along which it may be broken to form complementary, parti-cylindrical sections, and having another and shallower score adjacent and parallel to one of said deep scores, whereby after said cylindrical member has been broken along the deep scores to form the parti-cylindrical sections, the terminal edge of the particylindrical section having the shallower score may be broken off along said shallower score to adjust the size of the member as a whole to properly fit a smaller pole.
2. An article of manufacture comprising a hollow substantially cylindrical glazed vitrified member of substantially the proper size to fit a given pole, said member having deep scores on opposite sides thereof along which it may be broken to form complementary, parti-cylindrical sections, and having otherand shallower scores each adjacent to, and parallel with, one of said deep scores and so arranged that each complementary section, when these sections are broken free, will bear one of said shallower scores along, and spaced from, one free edge thereof, defining terminal breakable edge portions either or both of which may be broken away along the shallower scores whereby the member as a whole may be fitted to poles of three difierent diameters.
