spurs being foldable so that no part extends beyond the level surface of the shoe-when not required or whichthe spur elements may be projected outwardly and firmly held in such position when in use. l
Y These objects are attained by the novel design. construction, and combination. of
parts hereafter described and shown .in the` accompanying` drawings, forming a material part oiithis disclosure, and 1n which:-
Figure 1 isaperspective view showingV the lower portion or' ashoe and the application oit' the invention thereto. i
Fig. 2 is an enlarged longitudinal sectional view taken through the center of the device, as inserted in the sole.
Fig. 3 is -a plan view `ofthe device, the spurs being shown in a folded position.
Fig. 4 is a plan view ot the spur raising element in detail.
Fig. 5 is a side elevational view of the same.
Fig. 6 is a plan view of the spur reti-acting spring, and
Fig. 7 is a perspective view of one of the spurs.
Referring to the drawings, in Fig. 1, the sole of the shoe is indicated by the numeral 10, the heel by 11, and the upper part of the shoe in general by 12. The view shows the device in a closed position in the sole portion, while in the heel, the spurs are shown in an extended or operative position.
The device is comprised of a circular frame 15, adapted to be inserted in a suitably formed opening in the sole 10 or heel 11 and held therein by a plurality of rivets 16, three being indicated in the present construction, the heads of the rivets being positioned in depressions 17 formed in the Speccation of Letters Patent.

frame at equally spaced intervals near its periphery.
A hub 1S is formed at the center of the iframe, and bored to receive the body 19 of a bolt, formed with an enlarged portion 20 adjacent to the head 21, which is provided with a screw slot by means of which it may be held when applying the nut 2Q, which secures a. spring plate 25 having three equally 4disposed curved end elements 2G adapted `to be `contained within the frame.
Positioned midway between the rivets 16 are lugs 48 drilled transversely and suited to receive pins .30 .by means ofwhichthe spurs 32 are hingedly attached to the frame.
`Thelower outer end of the spur 32 is bentv inwardly forming hinge elements 33, and enveloping the pins 30, .a central. portion 34 being bent angularly to the main or body portion, and adapted to receive the thrust of the spring ends 26.
On the opposite end of the spur 32, the material is bent outwardly and reduced in widthat 35 `terminating in a sharp spur 36 adapted to engage with the ground or surface.
`The spurs are simultaneously raised by the outer plate 40, the .opening 41 turning on the enlarged portion 2O of the bolt and is providedwvithtwo perforations 42 uniformly spaced :from the central opening 41 and adapted to receive a pin wrench or the like by means of which the plate 40 may be rotated, one side ot the plate being flat and held closely against the web portion of the iframe 15.
Upon the opposite side of the plate 40 are raised and elongated cam shaped elements 43, the inner ends 44 of which are reduced to a thickness less than that of the main plate 40, the inclined portion 45 terminating in the main portion 43 which is curved at the ends 46 to a uniform radius from the opening 41.
In the main trame 15, are openings 48 through which the body portion of the spur extends, the angularly bent portion 45 resting normally upon the lowest part 44 of the cams formed on the plate 40.
When the key is inserted in the openings 42, and the plate 40 rotated, the point 36 of the spurs is caused to raise, the movement being continued by the profile 45 until the ends 4G of the plate make contact with the body 32, at which time the spurs are substantially vertical With respect to the plate and pressed again against the raised lugs 49 of the frame ele-ment l5, thus holding the spurs in an erect and operative position in the manner of a rise.
Upon the further turning of the element 40, in either direction, the spurs are retracted and folded closely against the frame by means of the spring ends 26 engaging with the prongs 34, the openings 48 being covered either by the plate ll0 or prongs at all times, thus preventing the entrance of dirt, etc.
In operation, when it is desired to make use of the spurs, a key or other suitable instrument is inserted Within the openings 42, rotating with the plate l0 and causing the spurs to raise as shown in the dotted lines in Fig. 2, or in full lines in the heel shown inFig. l, and it will be obvious that by further rotating the plate. i0 that the spurs Will be retracted into the positions shown in Figs. l, 2, and 3. p
Frein the foregoing, it will be seen that an effective device is indicated which can be instantly rendered operative by the wearer and which, when Vnot in use, in no Wise interferes with the customary use of the shoes to which the attachment is connected.
I claim l. In a non-skid device, the combination of a circular frame, adapted to be secured Within the sole or heel of the shoe, a plurality of spur elements hingedly engaged equidistantly therein, a spring element normally maintaining said spurs ina folded inoperative position, and a cam element adapted to raise said spurs into an operative position.
2. In a non-skid device, the combination of a circular plate adapted to be secured Within the heel or sole of the shoe, a plurality of spur elements hingedlyfengaged Within said frame, a prong formed With each of said spur elements extending angula-rly therefrom, a spring adapted to exert pressure against each of said prong elements whereby said spurs are held in a normally folded inoperative position, a plate rotatably engaged Within said frame, cam elements formed with said plate adapted to raise said spur elements, means formed With said cam elements and said frame whereby they are held in a rigidly extended position, and
means for rotating said cam plate wherebyV said spurs may be extended or retracted. Y
3. In a device of the class described, the
combination of a circular plate' having means for attachment, a central hub formed therewith, a spring rigidly engaged with said hub, spurs hingedly engaged Within said frame, at equal distances apart, prongs Fi formed with each of said spurs engageable with the ends of said spring, a plate rotatable on said frame, means whereby said plate may be rotated, cams formed on the opposite side of said plate, said cams being operable with relation to said spurs, and
means combined With said plate and said frame whereby said spurs may be rigidly CARL G. CLIFFORD.
