SPECIFICATION forming part of Letters Patent No. 729,265, dated May 26, 1903. Application filed November 12, 1902. Serial No. 130,979. (No model.)

To all whom it may concern:

Be it known that I,'PETER B. BRAZEL, a citizen of the United States, residing at Oheboygan, county of Cheboygan, State of Michigan,

have invented a certain new and useful Improvement in Snow-Plows; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to snow-plows; and it consists in the construction, arrangement, and combinations hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a'perspective View of the entire plow as arranged for. service. Fig. 2 illustrates the front section of the same. Fig. 3 is a sectional view through the attachment of Fig.2 to 'the main beam or tongue. Fig. 4 illustrates the attachment of the rear beam or tongue. Fig. 5 is a perspective view of the rear section. Figs. 6 and 7 are perspective views of the details of said rear section. Fig, 8 is a perspective view of the central section with one of the moldboards removed. Fig. 9 is a side elevation of the right-hand side of Fig. 8. Fig. 10 is a rear View of the left-hand side of Fig. 8 with the moldboard and attachments illustrated but detached therefrom.

Similar characters refer to similar parts.

In the drawings, A represents a pilot-sled with the usual runners and which is adapted to carry the front end of the device. To this is attached in the ordinary manner a tongue B, which has the usual attachments adapted for connection therewith of the proper team. About these matters there is nothing new whatever, and therefore they are not further illustrated or described.

Swiveled to a cross-beam connecting the runners of the pilot-sled is a main beam or keel C, which extends rearwardly entirely through all of the three removable sections ofthe plow. To this is attached by means of lifting and lowering the screws the forward section of the plow. (Shown in Fig. 2.) An intermediate or middle section, through which this beam passes, is shown in Fig. 8, and a rearward section is shown in Fig. 5. Each of -D (shown in Fig. l'in dotted lines) with a stirrup-strap D extending from the bottom end of the bolt back to the beam D. At the opposite extremity of the beam D means are afiorded for attached whiftletrees W on the under side thereof by means of a bolt and strap in the usual manner, to which whiflietrees a team may be attached, the beam ending with a seat S, and as the details of construction are unimportant and familiar it is not necessary to fully describe them. It is obvious that'the attachment of the beam D enables another team of animals to be employed, the services of which are very important, as

they are able to follow the track made by the plow, doing the majority of the work to the best advantage, leaving the pilot-team attached to the tongue B to do the breaking of the road and the steering only. The whole rear connection is sustained upon the runners R R, attached to the rear section. (Shown n. F s- Passing now to the details of the diiferent sections, that shown in Fig. 2 consists in a triangular structure made, primarily, of three pieces 1, 2, and 3. Pieces 1 and 3 are united at the apex 4 and cut down so as to leave an opening wide enough to insert the beam C and in which opening it may move vertically. Pieces 1 and 3 are also armed with flanged iron edges 5 and 6, so that they, together with the edges, operate somewhat in the nature of a moldboard to break the way. In this sense it constitutes what might be termed a pilotsection. A platform consisting of two pieces 7 and Sis firmly fastened to the triangular section 1, 2, and 3, and the rear piece 2 is cut down, so as to permit of the location of the beam 0 therein with the capacity of vertical movement.

The whole section of Fig. 2 is raised and lowered or adjusted with reference to the beam 0 by means of screws inserted in the nuts 9 and 10, the nut) being firmly fixed in the apex of this pilot-section and 10 being centrally located and firmly fixed to the piece 2 and directly underneathandtransverselycentral of the main beam (.1. The screws which engage these nuts are passed through the main beam. They are marked 11 and 12. They are fashioned with collars l3 and 14 on their shafts, so that they are longitudinally fixed, but rotatable in the beam 0. Hand- Wheels are furnished for these screws, whereby they may be rotated by persons located on the machine, and it is obvious that by rotating them the whole sect-ion (shown in Fig. 2) may be raised and lowered at either or both ends with reference to the beam 0, and there fore the lower edges of the side pieces 1 and 2, carrying the flanges 5 and 6, can be adjusted with reference to the work that is to be done.

Passing now to the second section, (shown in Fig. 8,) this is rigidly'but removably attached to the main beam by bolts 15 16, passing through cross-pieces 17 18. The section consists of two wing-boards 19 20, united by the cross-pieces 17 18 and also by a cross piece 21. Two platform parts 22 23 are so located that between them is left a channel for the main beam 0, the parts afiording braces resisting twisting strains. It will be noted, therefore, that this section is rigidly but removably connected to the main beam instead of being adjustably connected.

The cross-bar 21 carries at each end longitudinally fixed but rotatable screws 24 25 in a similar manner to those already described, 11 and 12. These may be operated by handwheels by attendants located on the machines. Thesescrews 2425, operating through nuts 32 on plow or moldboard sections 26, of which one is shown, 2b, in Fig. 8, (the corresponding one, 27, being omitted from that figure, but is shown in Fig. 10 detached,) afford means for raising or lowering the moldboards.

On the side plate 20 is firmly attached a metal plate 28, having undercut edges 29 29. The landside 30 of the moldboard is formed with rentering lips 31 31, which engage the undercut grooves 29 29, and thus allow the moldboard and landside, fixed together, to be vertically moved and adjusted, whereby twisting strains or detaching strains are firmly resisted. These moldboards 26 27 have depending points 28' somewhat at an angle to the general level of the machine and the lower edge of the landside 30. These points 28 28 may be adjusted so as to cut grooves in the frozen surface underneath the general lower plane of the plow, and as they are properly adjusted as to width between nloldboards 2e 27 the tongues cut these grooves properly for the purpose of affording tracks for lumber-sleds in case the device is used for the purpose of clearing out lumberroads, it being found much better to have tracks for such purpose, so that the runners of the sleighs can follow without sliding from side to side, than to leave a plane surface.

The rear section is illustrated in Fig. 5. It consists of the runners R R, united by crosspieces 33 34, upon which planking is attached, 35 35, leaving a longitudinal space or groove, between which is inserted the main beam 0, which is firmly but removably bolted to the cross-pieces 33 34. The front of this section is closed byavertical cross-piece extending over the top of the beam 0 and at right angles thereto, (marked 36.) To this piece are hinged by hinges 37 the wings F F. These are adapted to fold closely up to the sides or be spread out and braced by the adjustable braces G G. Each of these braces is made of two pieces- 38 39. Piece 38 is hinged at 40 to the runner R, and piece 39 is attached by dowel-pins 41 41 to the wing F by inserting the pins in the holes 42. By swinging the wing F olf and disengaging the dowel-pins the adjustable brace can be tolded in against the runner and the wing, then folded in and held by a book 43, engaging in an eye 44. Pivotally attached to the braced section 38 is a bail 45, and this engages the sectional part of the brace 39 in a slot 46, cut therein, and by swinging the bail outwardly slightly it can be relieved from the slot and placed in another slot, and so on, thereby adjusting the length of the brace as a whole. As these braces are alike, it is only necessary to describe one of them, the only variation being rights and lefts. In order to add to the stiffness of the brace and make it only longitudinally adjustable, a slot is cut in the portion marked 38 at 47, and a bolt 48, working in the slot, is fixed in the piece 39. As already stated, the side pieces R R of this section act as runners in conjunction with the pilot-sled A.

The operation of the device is apparent from the foregoing description, it being obvious that the adjustment can be made of the front section or of the moldboards or of the wing-pieces F F of the various sections, respectively, whereby both the depth of the cut or grooving and the width may be adjusted respectively, the forward plow cutting away the crust of snow in the center of the road, the central section, with moldboards, cutting out the track, while the wings of the third section take up the snow and turn it off one side clear of the track.

It is obvious that various changes in the construction and arrangements of the parts could be made and substituted for those shown without in the least departing from the nature or principle of the invention. It is also obvious that constructing the snow-plow as awhole in the separable parts, as described, it fulfils all the conditions necessary for efiicient work under all circumstances and is readily separable for loading on other vehicles for transportation in a compact form.

What I claim is- 1. In a snow-plow, the combination of a pilot bob-sled, a central rearwardly-extending beam, a front vertically-adjustable section attached thereto, a central section having vertically-adjustable moldboards also attached thereto and following the vertically-adjustable front section, and a third section having runners and adjustable wings, substantially as described.

2. In a snow-plow, the combination of a pilot bob-sled, atcentral rearwardly-extending beam, a front vertically-adj ustable section attached thereto, a central section having vertically-adjustable moldboards also attached thereto and following the vertically-adjustable front section, a third section having runners and adjustable wings, and a rearwardlyextending tongue pivotally attached thereto and adapted to be used as a means for attaching power, substantially as described.

3. In a snow-plow, the combination of a central rearwardly-extending beam, a verti- 'panding wings and carried upon runners, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

PETER B. BRAZEL.
