(Cl. 3,6f '59) .2 Claims.

--Galk-shoes are-generallyused by loggers, but

*theyare alsoworn-by wood cutters and byhunters and-persons fishing along 4 mountain streams,

because-theygive a firm footing'on logs, etc. There are certaindesirable featurescommonto all-theseuses, namely, the shoe-sole should have a certain degree of flexibility, since that gives the wearer of the shoe greater'ease and better footing in stepping f-romone logto another. In "the customary way of fastening the calks on desirable because not so tiring; and in summer Lighter time even loggers prefer lighter shoes. -weight shoes, of course, are not as expensive as the usual logging shoes,- but, with lighter weight -shoes, the soles are'thinner and generally not made of a very high-grade leather, and, in consequencainsertion of the calks tends to affect the life of the sole leather more or less.

l 1 'In orderlto reduce the cost of placing the calks incshoes and to-avoid injury to lighter-soles,

'metal plates with calks have beenmade for at- :taching to the shoe-soles, but such plates necessitate the sacrificing of all normal-flexibility of the shoe sole. Furthermore, since there is a great variation in the sizes of shoes single calked-plate attachments are required to be made in practically as many different sizes as there are sizes of shoes. This is due to the fact that the outermost rows of calks should be located close to the margin of the shoe sole, especially the lateral edges of the sole, otherwise the calks do not provide a suificiently sure footing.

The object of my invention is to provide an improved means for affixing calks to shoe soles; such means to consist of an assembly of calkedplate sections adapted to be afiixed to shoe soles, and arrangeable in spaced relationship or closely together, so that an assembly of calked-plate section may be affixed to the sole of a shoe of any size in such manner as to cover substantially the whole face of the shoe sole, or as much of the sole as desired, and permit some of the calks of the sections to be located close to the margin of the shoe sole.

Another object of my invention is to provide a calked-plate attachment which will not inter- ,fere .withthe normal flexibility Qf theshoesole,

which will be relatively inexpensive to make,

. whichmay be readily afiixed t and subsequently removed from ,theshoe sole without injuring the leatherof the sole. H

I .attain'the objects of my invention-byprovidinga calked-plate attachment which comprises an assembly of separate calked sections arrangeable on the shoe sole to which they are afiixed in such,.manner as L to cover a sufficient portion of theentireface of the sole; thecontours ofthe sections being shapedso asto aid the composite arrangement in conforming substantially. .With. the contour pf the margin of the .sole; the, outermost rowsof calks of the; sections being located. close to the outer margin of the sections, so that such calks may be located close 1 to the marginsof the ,shoe sole, when the sections. are .afiixed thereto. .Further. details of. construction of my invention are hereinafter described with referencetogthe accompanying drawingin which 7 "Fig-l is a sideelevationof ashoe provided I with mydivided adjustable calkedeplate, attachmenty Fig. -2 is a bottom-face view of the shoe ofiFig.

-Fig. 31s a similar bottomdaceviewof the mate of the-shoe of Figs; l-and'2 with thesections ,difierently arranged, and with fewer sections sections drawn *to alarger scale; and

Fig. 5 is a section taken on the line 5-5 of Fig. 4.

My divided calked-plate attachment comprises a plurality of separate similar sections a and b, separately attached to the sole and heel of the shoe as desired. One such section, a, is shown more clearly in Figs. 4 and 5, which figures are drawn to a larger scale. Referring to Figs. 4 and 5, the calked section a consists of a sole plate H], of suitable metal, on which are rigidly mounted the calks or spikes H. The plate I0 is provided with suitable apertures I2 through which screws or nails may be inserted for the purpose of fastening the plate to the sole of the shoe.

The plate It] is of suflicient thickness to afford strength and rigidity to the calked section and to constitute a firm anchorage for the calks or spikes H, but this plate should not be too thick in order not to add too much weight to the shoe. While the plate Ill is ordinarily flat, it may also be bent or preformed slightly, if necessary, to enable it to conform to the surface of a, particular part of the shoe sole, before being attached to the sole. However, the plate should be sulficiently rigid to prevent any bending with the use of the shoe when the plate is attached to the sole.

The shape of the plate i0 is important in my invention since the shape should be such that the plate can be set in various positions on the sole and so that a plurality of the separate calked sections can be used most efiectively to produce the desired result. The plate also should be relatively small in comparison with the total area of the sole surface. less trapezoidal shape, but with rounded corners (see l3 Fig. 4) and with at least one of the longer sides l5 slightly curved, proves very satisfactory.

The opposite long side I4 may conveniently be made substantially straight. The calks or spikes H are located relatively near the sides or edges l4 and I5. I have also found it convenient to have two sets of calked sections with the plates of both exactly the same size and shape but having faces oppositely-placed, as will be noted in comparing the calked sections a and b in Fig. 2.

Fig. 2 illustrates how a number of these separate calked sections a and b' (in this case a total of 10) can be arranged to cover practically the entire sole and heel surface. The sections a, and b are secured in place by suitable screws or nails it. The curved side or edge l5 of each section enables the sections to be placed so as to have their edges conform substantially to the curved edge of the shoe sole, thus making it possible to have a sufiicient number of the calks ll close to the lateral edge or margin of the shoe sole. This is an important feature of my invention. I-Iere tofore when attached calked metal plates have been used for shoes, the calks have been confined largely to the central area of the sole instead of extending to the edges and this has been one of the reasons why such calked plates have not been more favorably regarded as a substitute for the older method of attaching the individual calks or spikes directly to the sole.

In Fig. 3 I have illustrated how a smaller number of calked sections a and b (in this case '7) could be used on the same sole. The arrangement I have found that a more or Thus if the shoes are to be used in climbing on logs or over log rafts, it will probably be best to cover the sole and heel almost entirely, for example, as shown in Fig. 2; while in other cases the use of fewer calked sections, as in Fig. 3 would be ample. It is desirable however that'enough sections be attached to the sole to provide calks substantially around the border portion of the main part of the sole. It is also important that the calked sections should neithenbe too small nor too large, and I have found the comparative size illustrated to be very satisfactory. In many cases it will also be found preferable to leave the calked sections off of the heels entirely.

From Figs. 1, 2 and 3 it will be apparent that my calked plate attachment, composed of a number of separate sections, will interfere but little, if any, with the normal flexibility of the shoe sole. It will also be apparent that these individual calked sections may be attached to, and subsequently removed from, the sole easily, and without injury to the sole. Also, due to the shape and size of these individual sections, my calked-plate attachment may be removed from one pair .of shoes and used subsequently on another pair of shoes of entirely different shape and size.

The illustrations of the modes in which I carry my invention into practice, given by the drawing, are to be understood as describing only convenient modes. Various other arrangements of the sections would of course be possible, and. the shape of the individual sections could also be varied without departing from the principle of my invention.

I claim:

1. A calked-plate attachment for shoes, of the character described, comprising a plurality of calked-plate sections, each section consisting of a metal plate of relatively small area compared to the area of the shoe sole, said plate having one curved edge, calks rigidly attached to said plate, with a row of said calks located near said curved edge, and means for attaching said plate-to. the

. shoe sole.

- sisting of a metal plate, substantially trapezoidal in shape, having rounded corners and having one curved edge, calks rigidly attached to said plate, with a row of said calks located near said curved edge, and means for attaching said plate torthe shoe sole.
