Y. l Z 7 lllllllllllllll IIIIIIII IIIIII 'IIIIIIIIII Patented Apr. 23, 1935 UNITED STATES PATENT OFFICE ATTACHMENT FOR SHOES John O. Brown, south Weymouth, Mass.' Application May 9, 1934, Serial No. 724,780 V5 claims. (o1. sis- 7.7)

I My invention relates to attachments for the soles of shoes and it has for its objectto provide an improved attachment for application to the sole of a golf players shoe and which, when in use, will alTord the player better foothold than isv afforded by the ordinary golf players shoe. It is also an object of this invention to provide an attachment ofthe character described'which will be of simple, inexpensive and elicient construction; which may be quickly applied to or removed from the sole of a shoe, and which will be adapted to be iitted to soles of different sizes.

. To these ends I have provided an attachment for the sole of a shoe, said attachment having the peculiar features of construction andmode of Operation set forth in the following description,

the several novel features of the invention being separately pointed out and dened in at the close thereof.

In the accompanying drawing: Figure 1 is a bottom plan view .of an attachment constructed in accordance with this invention.V f

Figure 2 is a section on line 2 2 ,of Figure 1. Figure 3 is a section On line 3-'3 of Figure 1. Figure 4 is an elevation, partly broken away, of a wrench for use in connection with the attachment illustrated in Figures l to 4, inclusive.

The illustrated embodiment of my invention comprises two tread members indicated generthe claims ally at I and 2, said members being iitted to andV covering the bottom of the forepart of 'the sole of a shoe which is indicated by dotted lines at S in Fig. 3.

The tread member 2 comprises a solid Outer marginal portion 3 formedwith a longitudinal series of threaded holes 4 bordering the outer edge of said tread member while the inner portion of said tread member 2 vis formed with a horizontal slot 5 extending from end to end ofisaid mem'- ber, said slot being the space between two walllike extensions 6 and 'I of the solid outer marginal portion 3.

'I'he tread member I comprises a relatively thick outer side marginal portion 8 and an inner relatively thin blade or wing portion 9 which occupies a position within the slot 5 oi member 2 and which is pivotally connected adjacent to the toe end of the device to the walls 6 and I of member 2 by means of a pintle I0.

At its rear end the tread member I is made with a laterally and inwardly extending arm Il formed along its inner side with an arcuate rack of teeth I2 which is concentric with the axis of pintle I 0.

This arm II occupies the slot 5 and its rack of teeth I2 is engaged by a pinion I3 havingtrunnions I 4 and I5 journaled in apertures provided in the walls 6 and 'I of tread member 2. The lowermost trunnion` I5 is made with a hexagonal extension I6 adapted to receive upon it the lower end of a wrench II, said lower end being made with a hexagonal socket I8 to iit the hexagonal portion I6 Of trunnion I5. Y

When the wrench II is applied to the hexagonal portion I6 of trunnion I5 and rotated it acts through pinion I3 and rack I2 to swing the two tread members I and 2 relativelyon pintle I0 toward or from each other. 1 v

The tread member 2 is made upon its top side and adjacent to its periphery with an upstanding jaw or lug I9 to it against the side of the shoe sole s as indicated inFig. 3, while the tread member I is made upon its top side and adjacent to its peripherywith two upstanding lugs or'jaws I may be made shorter than the spikes 24 ofV tread `member 2.

All ofthe spikes or calks 24 and 26 are made with hexagonal base portions 2l each of a size to iit `into the socket I8 of wrench I1.

It is a feature of this invention that the spikes or calks 24 and 26 are removablyl mounted in the threaded holes 4 and` 22 so that I may provide with each attachment a number of spikes of different lengths so that the' user of the attachment can incorporate in the device spikes ofthe length suitable for him or spikes of different lengthsasdesired. Frequently a user is best suited with spikes of one length applied to the tread member I and spikes of another length applied to the tread member 2, and as will be clear, the wrench II provides an implement by means of which the spikes may be quickly applied to Or removed from the tread members. This wrench I1 is also used, as pointed out above, to Operate the pinion I3, which is a matter of considerable convenience.

Between the walls 6 and 1 of tread member 2 and adjacent to the rear end thereof, is a spring detent 3 I, Fig. 1, whose free end presses yieldingly against the pinion I3 and engages the teeth thereof to prevent rotation of the pinion in one direction. Detent 3l is constructed with a lateral projection 32 occupying a slot formed in the bottom wall 1 and by means of this projection the detent can be manually disengaged from the pinion without removing the device from the shoe.

In applying the attachment to the sole of a shoe it is placed in position against the forepart of said sole while the two tread members i and 2 occupy more or less separated relationship. Then by means of the wrench Il applied to the hexagonal portion I5 of the trunnion of pinion I3 the latter is rotated in a direction to forcibly swing the two tread members together so that their lugs IQ, 20 and 2| are forced against the opposite edges of the sole s'. When the attachment is thus adjusted so as to firmly grip the sole the spring detent serves to lock the parts in their sole-gripping positions.

What I claim is:

l. An attachment of the character described for application to the forepart of the sole o'I a shoe, said attachment comprising a pair of tread members having their forward ends pivotally connected, one of said members being disposed at one side oi said forepart and made with an arcuate rack of teeth concentric with said pivotal connection and the other of said members being disposed upon the opposite side of said Iorepart, and a member-operating element rotatably mounted on said last-mentioned member and meshing with said rack of teeth, said element being operable when rotated in one direction to swing said two members relatively toward each other thereby to xedly clamp the attachment tothe opposite side edges of said forepart and when rotated in the opposite direction to swing said two members away from each other.

2. An attachment of the character described for application to the forepart of the sole of a shoe, said attachment comprising a pair of tread members having their forward ends pivotally connected, one of said members being disposed at one side of said forepart and made with an arcuate rack of teeth concentric with said pivotal connection and the other of said members being disposed upon the opposite side of said forepart, and a'toothed member-operating element rotatably mounted on said last-mentioned member and meshing with said rack of teeth, said element being operable when rotated in one direction to swing said two members relatively toward each other thereby to xedly clamp the attachment to the opposite side edges of said forepart and when rotated in the opposite direction to swing said two members away from each other.

3. An attachment of the character described for application to the forepart of the sole of a shoe, said attachment comprising a pair of tread members each provided upon its top side and at its outer edge with a soleaengaging lug and upon its bottom side with a plurality of spikes, one of said members being disposed at one side of said forepart and made adjacent to its rear end with an arcuate rack of teeth and the other of said members being disposed upon the opposite side of said forepart; means pivotally connecting said members adjacent to their forward ends and with respect to which said arcuate rack of teeth is concentric, and a pinion rotatably mounted on said last-mentioned member and meshing with said rack of teeth, said pinion being constructed with a trunnion having an extension projecting below the bottom of said last-mentioned member which extension is non-circular in cross section thereby to adapt it for engagement with a wrench by which said pinion is rotated in one direction to swing said two members relatively toward each other thereby to xedly clamp the attachment to the opposite sides edges of said iorepart and by which said pinion is rotated in the opposite direction to swing said two members away from each other.

4. An attachment of the character described constructed in accordance with claim 3 wherein one of said tread members is made with a horizontal slot within which said pinion is mounted, and wherein the other of said members is made with a relatively thin blade occupying said slot and on which said arcuate rack of teeth is provided.

5. An attachment of the character described for application to the forepart of the sole of a shoe, said attachment comprising a pair of tread members each provided upon its top side and at its outer edge with a sole-engaging lugr and upon its bottom side with a plurality of'spikes, one of said members being disposed at one side of said forepart and made adjacent to its rearend with an arcuate rack of teeth and the other of said members being disposed upon 'the opposite side of said forepart and formed withv a horizontal slot into which said firstmentioned member extends; means pivotally connecting said members adjacent to their forward ends and with respect to which said arcuate rack of teeth is concentric; a pinion'rotatably mounted on said last-mentioned member within said slot and meshing with said rack of teeth, said pinion being constructed with a trunnion having an extension'projecting below the bottom of said last-mentioned member which extension is non-circular in cross secz tion thereby to adapt it for engagement with a Wrench by which said pinion is rotated in one direction to swing said two members relatively toward each other thereby to fixedly clamp the attachment to the opposite side edges of said forepart and by which said pinion is rotated inl the opposite direction to swing said two members away from each other, and means adjustably mounted on said last-mentioned tread member and engaging said pinion to lock the latter in its adjusted position.
