ANTISLIPPING DEVICE.
u Specication of Letters Patent.

Application led October 11, Y1916. Serial N o. 124,9(65.
To all whom t may concern.' I
Be it known that I, FRITZ IsoHER, a citizen of the'United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Antislipping Devices, of which the following is a specication.
This invention relates to anti-slipping devices. An anti-slipping device involving the invention can be put to various uses; it is of particular advantage, however, when applied to an article of footwear to increase the hold of the wearer `upon slippery surfaces whether of ice, slime or otherwise. One of the objects of the invention is to provide an article of the character set forth which is simple in construction, which can be easily applied and which preferably has a calk member movable as desired into and out of operative position.
In the drawings accompanying and forming part of the present specification I have shown in detail one convenient form of embodiment of the invention which I will set forth fully in the following description. I do not restrict myself, however, to this disclosure; I m.y depart therefrom in several respects within the scope of the invention deined by the claims following said description.
Referring to said drawings:
Figure l is a side elevation of an antislipping device involving the invention showing the same applied to the heel of a shoe partl Y represented, the calk member being shown inits operative and inoperative positions by full and dotted lines respectively. V
Fig. 2 is a top plan view of the device with the calk member in its operative position.
Fig. Bis a longitudinal section on the line 3-3 of Fig. 2, looking in the direction of the arrows and showing said calk member in several positions by full and dotted lines.
Fig. 4 is a perspective view of a locking or clamping member. Y
Fig. 5 is a detail view on an enlarged scale of a joint.
Like characters referto like parts throughout the several views.
' The article includes an attaching element` Vfinger piece l1 so as to cause the y of the plate 12 to impin'geaigainst 'th'eback Y such as'that denoted in a general way kby 2. This attaching element in the-present case .isof such character the heel of a shoeas 3. The attaching element is'of sectional construction as shown, comprising the sections 4 and-V5. TheV scction 5 is shown provided at its forward-end and sides with two upstanding hooks 6 adapted to engage the front face of the heel of the shoe as will be hereinafter more particularly described. The rear section 4 isV shown as forked, the branches lof its fork being provided ward extensions or ears as 7 adapted to eX- tend throughv transversely alined elongated slots as 8, there being as shown two rows of such slots near opposite sides respectively of the front sectionVv 5. These l 'are adapted to interchangeably enter transversely alined slots, being shown as occupying the two forward ones in Fig. 2, to thus vary the length of the attaching or mounting element 2 and adapt it to the particular heel to which the device is to be applied. From the `rear side of the rear section 4 there rises the projection 9 through which is threadedthe screw l0 shown furas to be associated with i' vat their free ends with upugs or ears 7 nished with a winged head 11. The screw is i connected by va swivel joint at its front end with a plate l2 having at its ends prongs as 13 adapted to be pressed into the heel of the shoe-to hold the device in place. From the ends of said plate 12 at the lower edge there-V into ap- V the shoe and thefree ends of the hooks or bent tongues 6 brought into engagement with the front surfaceof the heel, it being understood that the forward and Vupper section 5 is solid against the bottoni of the heel Yandthat the section 4 likewise fits flatly against the lrcompl'emental When this is .done the screw l0 will be run inA bythe manipulation of the thumbV or prongs 13 firmly and section 5.`
of the heel and thus substantially clamp the attaching element in position.
In addition to the attaching element there is a calk member as 15. In the present case this calk member is pivotally connected with the attaching member, being preferably jointed to the front and upper section 5 thereof. This calk member like the sections of the attaching element 2 is preferably, although not essentially made from sheet metal. Sheet metal is desirable, however, in that the parts can be readily stamped from suitable stock and subsequently shaped up with the aid of suitable dies. The fiat plate-like body of the calk member is shown provided with prongs or pointed teeth as 16 at the corners thereof and which are adapted to penetrate a surface when the calk member 15 is in operative position, at which time it fits practically flatwise against the under face of the forward portion of the rear section 4 as shown for instance by full lines in Fig. 3. This chalk member in addition to the operative position is adapted to occupy an inoperative position as shown by dotted lines for example in Fig. 1, at which time it fits the hollow of the shoe forward of the heel. In Fig. 3 I have shown by the upper dotted lines the calk member in its inoperative position and by the second series of dotted lines in an intermediate position. In the intermediate position the calk member is supposed to be moving either toward operative or ino erative position. Where the shanks of t e hooks 6 join the body of the front member 5 the stock is rounded as at 17. At the heel or where the projection 9 joins the section 4, the stock has a bulge 18, these three rounded projecting portions being adapted to bear on the supporting surface when the calk member is in its inoperative position so as to prevent injury to such surface. These bearing portions, owing to the fact that they are rounded, can not cut into fabric such as carpet or even wood when the calk member is in its inoperative position.
The calk member 1 5 has a bent neck 19 disposed in the slot 2O open at its front end and situated in the front upper section 5v about midway of the width thereof. This neck terminates in lugs 21 perforated to receive pintles as 22 on said section 5. To connect the part 15 with the part 5, the slot 20 will be expanded to separate the transversely alined pintles or studs 22. When this is done the neck 19 will be introduced into the slot 2O until the perforations of the lugs or ears 21 are opposite the pintles when the section 5 will be contracted to project the pintles into the perforations and thus pivotally unite said parts 5 and .15. The neck 19 terminates in a curled portion Gopils of this patent may be obtained.` for ve cents each, by addressing the 23 adapted to be engaged by the free end of the spring 24 preferably integral with the extension and extending as shown forwardly from the rear wall of the slot 20. The free end of this spring 24 is adapted to alternately engage opposite faces of the curled portion 28 to thus hold the calk member 15 in its two positions and against accidental movement.
To facilitate the movement of the calk member 15, the latter may as illustrated be provided with the laterally extendingnger 25 adapted to be engaged by the foot to effect the movement of the calk member from operative to inoperative position or vice versa.
I might call attention to the fact that the stock of the rear section 4 especially along the projection 9 and where said projection joins the body of said section is transversely channeled or bowed. This produces a bead or rib which unites with the bulge 18 and thus materially increases the strength of the article at such point.
What I claim is:
1. An anti-slipping device comprising an attaching element having on the under surface thereof a series of rounded bearing projections, and a calk member connected with the attaching element for movement into and out of operative positions respectively, the calk memberwhenin the operative position fitting against said under surface and when in the inoperative position uncovering said under surface to leave said bearing projections exposed.
2. An anti-slipping device comprising attaching element and a calk member, the attaching element consisting of sheet metal sections, the forward one of which has upstanding heel-engaging hooks and also has longitudinal rows of slots, the slots being transversely alined, the other section having projections to interchangeably t the slots and also having an upstanding projection at its rear, a screw threaded through said upstanding projection, and a plate in swiveled connection with the screw and provided with forwardly extending prongs and rearwardly extending arms straddling said projection, the calk member being pivotally connected with the front section of the attaching member for movement into operative and inoperative positions and said front section having an integral spring to hold said calk member in said positions.
In testimony whereof Iv affix my signature in the presence of two witnesses.
