A'Applicationv filed April 29, 1922. Serial No. 557,432.

To @ZZ to hom t may concern 13e 1t known that T, Dnarnrnn TULKAN, a citizen of the United States of America, re-

siding at Cleveland, in the county of Cuyaboga. .and State of Qhio,.have invented new and useful Improvements in Shoe Attachments, of which the following is a specification.

This invention relates to attachments for shoes, and has for an object the provision of means which may be attached to a shoe for the purpose of converting an ordinary shoe into a non-slip or hob nail shoe, whereby a firm footing may be obtained upon stony or slippery surfaces.

Another object of the invention is the provision of a device of this character, which may be remo-vably attached to the heel of a shoe and which in addition, may be moved into and out of position for use, so that the wearer of the device may wall: upon carpets, or other floor covering without injury thereto. l

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of the invention attached to a portion of a shoe and shown in position for use.

Figure 2 is a similar view with the antislipping plate moved to an inactive position.

Figure 3 is a bottom lplan view with the parts in the position shown in Figure 1.

Figure 4 is a rear elevation of the same.

Figure 5 is a central longitudinal sectional view with the parts in the position shown in Figure 4.

Figure 6 is a bottoni plan view with the parts in the position shown in Figure 2.

Figure 7 is a central longitudinal sectional view of the same.

Figure 8 is a perspective view of the invention removed from the shoe.

Referring in detail to the drawings, the reference character 10 indicates the heel of a shoe, which may be of ordinary character. The invention which is removably attached to the heel comprises an attaching plate 11, which is shaped to conform substantially to the shape of the heel 10 and which is provided at one end with upwardly extending spaced ears 12 and at its opposite end with an upwardly extending ear 13, the last mentioned ear being located approximately central between the ears 12. The ear 13 is provided with a threaded opening for the reception of the screw 14 and the latter is provided with a knurled head 15, whereby the end of the screw may be impinged against the rear end of the heel, with the ears l12 engaging the forward edge of the heel to securely hold the plate 11 in place.

Hingedly secured to the forward end of the plate 11 as. shown at 16, is a plate 17, the latter having extending from one face a plurality of spurs or projections 18, so that when the device is arranged as shown in Figure 1, these spurs or projections will eX- tend downwardly and provide a grip. EX- tending from the end of the plate 17 opposite the hinge 16, is a spring tongue 19, which is adapted to engage a lip 2O formed at the base of the tongue 13. This will serve to hold the plate 17 in the position shown in Figure 1, but will permit of ready detachment so that the plate may be swung to the position shown in Figure 2. In thisposition the spurs or projections 18 will extend upwardly and will lie beneath the instep of the shoe, so that the smooth face of the plate 11 will provide a tread surface for the heel. The hinge 16 is so positioned as to lie above the plane of the lower face of the plate 11 when the device is attached.

In order to hold the plate 17 in the position shown in Figure 2, the plate 11 has e1:- tending therefrom a spring finger 21, which fric-tionally engages the hinged portion of the plate 17 so that the latter will be held against accidental movement. This will prevent the plate 17 from swinging downward when the device is arranged as shown in Figure 2 and thus prevent tripping of the wearer. While the spring finger 21 will ordinarily serve to hold the plate 17 in the position shown in Figure 1, the spring tongue acts as a further safeguard and prevents accidental downward movement of the plate 17 in the event of the spurs or projections catching within the surface over which the wearer may be walking.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make suoli changes as properly fall within the scope oi the appended claim.

Having described the invention what is claimed is Y A shoe attachment of the class described comprising a plate adapted to be engaged against the heel of the shoe, a clamping lug on one end of the plate formed with an aperture7 a clamping screw threaded through the opening and engageable with Vthe heel of the shoe at the rear of such heel, upwardly e2- tending ngers integral with the forward edge of the plate and engageable with the heel of the shoe at the front thereof andy cooperating with the first named finger to hold the plate securely upon the heel of the shoe,

a second plate in face to face Contact with the first mentioned plate, a hinge connection between the 'second plate and the: first plate at the forward portion of theheel whereby `the second mentioned plate may be swung out of enga-gement with the first plate to an inactive position, said second named plate being orinedwith teeth, said first mentioned finger at its juncture with the first named plate being pressed outwardly to form a knob and a spring tensioned ear on the rear edge of the second named plate engageable over said knob whereby the second named plate may be held in contact With the first named plate when in active position.

ln testimony whereof I affix ,mysignature DEMETER TULKAN.
