SOCKET PLATE FOR SHOES.

application med muy av, 1922. serial No. 577,85,

To all w hom t may concern Be it known that I, GEORGE BELL, of 166 Craigton Road, Glasgow, Scotland` a subject of the King of Great Britain, have invented certain new and useful Improvements Relating to' Socket Plates for Shoes, of which the following is a specification.

This invention relates to boots and shoes as used for sport, climbing, athletic and other purposes. Such boots and shoes are usually made specially and are provided with spikes, studs or projections to grip the ground.

It has however, been proposed to insert in the sole screwed sockets heldin place by sole plates and provided: with spikes or studs which could be screwed into the sockets. So far as I am aware previous socket plates had a number of disadvantages; in the first place they were of cast metal and the sole plate was consequently of yconsiderable thickness in order to give the required strength, and was liable to be felt by the wearer even although a recess to receive this sole plate was cut in the sole. Further in some cases, the tubular socket portion had a hole passing completely through so that it could be 'throughout its ywhole length, and there was no protection against an eXtra long stud projecting internally and causing the wearer considerable discomfort. v In other socket plates the socket had its bottom closed by the sole plate and it could not therefore be screwed right to the bottom of the hole, with the result that very frequently there was so little thread to grip the stud that the latter became loose in a very short time and either came away by unscrewing or by stripping the thread.

It is one of the objects of the presentinvention to provide a socket plate in which the socket can be screwed right to the bottom and yet has its internal end closed so 45 as to prevent its stud being screwed inwardly to too great an extent.

Another disadvantage of cast socket plates is that the threads are not as sharp and therefore do not take as good a hold as the threads in malleable metal; further, cast metal threads are much more liable to stri-p screwed than sheet metal threads; again, a cast socket is liable to break off from the base plate under any exceptional stress.

According to the present invention the socket plate is made of sheet metal (preferably thin sheet steel) in two parts which parts are put together and welded.` In this way I obtain the advantage in manufacture of making the parts separately, combined with the advantage in use of a rigid singlepiece socket plate.

The sole plate is formed with upstanding perimetrical projections and arcuate slots whilst the tubular socket is internally screwed and is open ended and has preferably four projections, two adapted to rest on the one surface of the plate and the other two to pass through the slots aforesaid and bear against theother surface of the plate sothat, by welding or other proc ess, the two parts of the socket plate can be secured together with absolute rigidity. The plate may be slightly dished or counter sunk for the reception of the two projections of the socket last referred to so that they,

when welded, will lie flush with the surface of the plate.

The yplate is preferably ofl a. polygonal formation with two or more) upstanding sharp projections.

Socket plates made from sheet metal and from tubing as hereinbefore described are lighter and stronger than cast metal sockets and they eliminate the difficulty of prop erly cutting the internal screw threads in y the blind holes of the latter.

y The invention is illustrated, by way of example, on the accompanying drawing, whereon:- j

Figs. l-6 illustrate steps in the manufacture of the socket plates.

Fig. 7 shows a screwed spike fitted in the socket plate.

Fig. 8 shows in elevation and plan a screwed stud which can be substituted for the spike of Fig. 7.

Fig. 9 shows, in sectional and outside elevation, a screwed conical headed stud with leather or rubber discs' suitable as a stu for football boots, and the like.

Figs. 10 and 11 show th." application of the socket-plates to a leather boot or shoe, Fig. 10 being an inverted plan and Fig. 11 a section on the line 11-11 or' F ig. 10.

Fig'. 12 is an elevation and Fig. 13 an inverted plan of a punch employed in preparing the sole or heel of the shoe 'lor the reception oi the socket plates.

F 14 is a perspective view and 15 a plan of a key for use when attaching and detaching different studs and spikes.

As illustrated, Figs. 1 and 2, blanks 16 for the sole plates are stamped from sheet steel 17. Each blank is olf polygonal shape with `four sharp star-pointed projections 18, and two oppositely disposed arcuate slots 19 2) are out in the central part there-of?. After being stamped the blank is subjected to the action of a die or former whereby the central part is bulged, as at 20, to torni an arch-shaped recess' in the rear tace, and the projections 18 are bent over at right angles as shown in Figs. 3, 5, 6 and Sockets 21 (Fig. 4) are cut from a length of internally screw threaded steel tube and each is sawn across at one end to form four separated quadrantal portions 22. rFwo oppositely disposed portions 22 are then turned outwards at right angles to7 the anis of the socket which is then ready to be attached to the sole plate 16 formed as already described. This is done by simply inserting the other two portions 22 through the slots 19 in the plate and then kturning them back into the recess formed by the bulged part 2O (see Figs. 5 and 7) of the plate 16. rlhe portions 22 of the socket 20 thus constitute projections which bear on opposite sides of the sole plate (Fig. 6) and hold the socket member firmly in place. As the projections 22 on the rear side of the plate occupy the archshaped recess formed by the bulge 2O they do` not stand out from the hack but lie flush, therewith.

After the socket 21 and plate 16 have been connected they are preferably welded together, the metal used in welding filling the central recess in the rear face of the plate. rlhe studs or spikes 23 (Figs. 7, 8 or 9) have their Shanks 24 adapted to screw into the socket 21.

To apply the plates to boots or shoes, holes corresponding to the sockets 21 are made through the outer sole or ply leather and the socket plates (Fig. 6) are pressed into place from the inner face of the leather, as illustrated in Figs. 10 and 11, the sockets 21 occupying the holes, and the projections 18 being sunk into the leather to hold the socket plates against movement. The operation of fitting the sockets is facilitatednand expedited by employing the punch 25 shown in Figs.` 12 and 13. This punch has a central punch 26 corresponding to the socket 21, and peripheral projections 2T corresponding to the projections 18, so that the hole forthe Lmaeeo reception ot the socket and indentations for the projections can be made in the leather simultaneously.

After the socket plates have been litted 'the studs or spikes can be inserted or removed at any time. For inserting studs or spikes having polygonal heads or parts, as illustrated in Figs. 7 and 8, a key 28 (Figs. 14 and 15) may be supplied. The key, which can be easily carried in the pocket, is .stamped from sheet metal bent up at each end, as at 29, and a number of polygonal openings 30 are 'formed therein to fit studs or spikes of three different sizes.

rlhe screwed spikes sho-wn in Fig. may oe used for running or other athletic purposes and the studs shown in Figs. 8, 10 and 11, may be used for golfing, climbing', etc. For golfing, the sockets 21 and the studs may be screwed lett handed so that when the user turns in playing his shot there will be no tendency to unscrew the studs.

The stud suitable for :football boots shown in 9 comprises two leather discs 31 pressed into the shank of the stud 23', the outer disc being counter sunk to receive the head of the stud. The head is attached to the boot by simply screwing the projecting end of the shank 24 of the stud into the socket 21 ot' the boot.

lit desired, a washer may be fitted between the stud and socket as shown at 32, Fig. 8.

Having now fully described my invention what 1 claim and desire to secure by fietters Patent is 1. A socket plate for boots and shoes adapted to receive screwed studs, spikes and the like, comprising a thin sheet metal sole plate formed with slots', and a separate tubular screwed socket rigidly attached to the plate, said socket having split end portions inserted through said slots and bent back against the plate, and the screwl of the socket extending right up to* the plate.

2. A socket plate for boots and shoes adapted to receive screwed studs, spikes and the like, comprising a thin sheet metal sole plate formed with arcuate slots, and a separate tubular screwed socket welded to the plate, said socket having split end portions inserted through said slots and bent back against the plate, andthe screw of the socket extending right upl to the plate.

3. A socket plate for boots and shoes adapted to receive screwed studs,- spikes and the like. comprising a thin sheet metal sole plate formed with upstanding perimetrical projections and concentric arcuate slots, and a separate tubular screwed socket welded to the plate. said socket having split end portions inserted through said slots and bent back against the plate, and the screw of the socket extending right up to the plate.

4. A socket plate for boots and shoes adapted to receive screwed studs, spikes and llfl the like, comprising a thin metal sole plate formed With upstanding perimetrioal projections, a (lished centre portion and arcuate slots in said portion; and a tubular socket rigidly attached to said plate, said socket having split end portions bearing on opposite sides of the plates those bearing on the underside passing through said slots, and
