Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed June 21, 1916. Serial No. 105,048.

To all whom it may concern:

Be it known that I, l/VILLIAM A. BEARD, a citizen of the United States, residing at Ayer, county of Middleserr, State of Massachusetts, have invented an Improvement in Ice-Creepers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to ice creepers such as are adapted to be attached to the sole of a shoe, and has for its object to provide a novel device which is simple in construction and in which the holding spurs can be thrown into either operative or inoperative position at the will of the wearer.

When the holding spurs are in operative position they project below the sole of the shoe and will be forced into the ice or other slippery surface on which a person is walking, thus preventing the person from slipping. When the holding spurs are in'their inoperative position they are entirely out of the way and do not have contact with the surface on which a person is walking.

My improved ice creeper can be attached to the shoe in any suitable way either by screwing it to the sole of the shoe or by providing it with straps by which it may be strapped in place.

In order to give an understanding of the invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims. 1

- Figure 1 is a side view of a shoe having my improved ice creeper applied thereto;

Fig. 2 is a view of the ice creeper detached;

Fig. 3 is an underside plan view thereof; Fig. 41 is a view similar to Fig. 2, but showing the holding spurs unlocked; Fig. 5 is a section on the line 55, Fig. 2.

My improved ice creeper is designed to be secured to the sole 10f a shoe 2 beneath the shank thereof and directly in front of the heel 3.

4: is a plate of metal which supports the holding prongs OlfqtllG ice creeper and which is adapted to be secured to the sole 1 'of the shoe in some suitable way. Said plate may be fastened directly to the sole of the shoe by attaching screws which may be inserted through apertures 5 in the plate, or said plate may be riveted to a strap 31 by which th e e ca be p ed to the sole of a shoe, as shown in Figs. 1 and 2. This construction is shown in Figs. 1 and 4., the rlvets being shown at 32. The particular way in which the plate is secured to the shoe is not important to the invention.

The holding prongs are shown at 6, there being two in this embodiment of my invention. These prongs are secured to a bar 7 which is secured to the plate 4:. The holding prongs 6 can conveniently be made by bending the ends of the bar 7- at right angles and sharpening them as shown. The plate 4 is provided with two cars or upturned portions 8 and 9 in which the bar 7 is received, said ears being each provided with a square aperture 10 through which the bar extends. The bar 7 is formed to present two squared portions 11 and 12 at each end thereof and two round portions 13 and 14 adjacent the square'portions. The square portions 11 and 12 are of a size to fit the square apertures 10 in the arms 8 and 9. Whenthe bar 7 is in such a position that said square portions 11 and 12 occupy the apertures 10, as shown in Fig. 2, the bar, will be held from' turning movement and will be locked to the plate 4:. On

the other handQwhen the bar 7 is shifted longitudinallyw into the position shown in Fig. 4 thereby to bring the round portions 13 and let in the apertures 10, then said bar can be turned I so as to throw the holding spurs 6 from the full to the dotted lineposition, Fig. 1 or vice versa.

WVhen the ice creeper is to be used the bar is turned so that the holding spurs 6 are pointed downwardly and then it is moved longitudinally to bring the square portions 11 and 12 into the apertureslO, thereby locking it from turning. In order to hold the bar from longltudlnal movement when the spurs are in their operative position, I have provided a spring-pressed locking pawl 15 which is adapted to engage a shoulder 16 formed on the bar 7, as seen in Fig. 2. This locking portion 15- 's carried by a resilient arm17 which is herein shown as extended from the arm or ear 9. Said arm 17 is also provided with the lateral extensions 18 forming finger pieces by which it may be manipulated to release the locking pawl from the shoulder 16.

Nhen the holding spurs are in their 0perative position, as shown in Figs. 1 and 2, the bar 7 is held from turning movement by the cooperation of the squared portions 11 and. l? with th qu d apertures 10 and,

r they will be entirely out of the way and out of contact with the ground. The bar 7 may then be moved longitudinally again to bring the squared portions 11 and 12 into the apertures 10, thus locking the bar with its spurs in inoperative position. The device is very simple and easy to operate and the spurs can be easily turned into inoperative position when they are not needed, thus obviating the necessity of removing the device from the shoe.

While I have illustrated herein one embodiment of my invention, I do not wish to be limited to the constructional features shown.

I claim:

1. In an ice creeper, the combination with a plate adapted to be secured to the sole of a shoe and bent to present at each end thereof an upturned ear, each ear having a square aperture therein, of a bar having holding spurs and extending through the apertures in said ears, said bar having non-circular portions of a size to fit the apertures and also other portions capable of rotation in said apertures, said bar being slidable longitudinally in the apertures to bring either the non-circular or other portions into said apertures, one of said ears having a locking latch extending therefrom adapted to engage said bar and lock it in a position in which the non-circular portions occupy the apertures.

2. In an ice creeper, the combination with a plate having upturned ears, of a bar provided with holding spurs and mounted in said ears for longitudinal movement, said bar in one position being free to turn to carry the spurs from operative to inoperative position and in another position being locked from turning movement, and means to lock the bar from longitudinal movement when in the latter position.

3. In an ice creeper, the combination with a plate having upturned ears, of a bar provided with holding spurs and mounted 1n said ears for longitudinal movement, said bar in one position being free to turn to carry the spurs from operative to inoperative position and in another position being locked from turning movement, and a looking latch carried by one ear and adapted to have locking engagement with the bar to lock the latter from longitudinal movement.

4. In an ice creeper, the combination with a plate having upturned ears, of a bar provided withholding spurs and mounted in said ears for longitudinal movement, said bar in one position being free to turn to carry the spurs from operative to inoperative position and in another position being locked from turning movement, said bar having a shoulder, and a locking latch adapted to engage said shoulder and lock the bar positively from longitudinal movement when it is locked from turning movement.

5. In an ice creeper, the combination with a plate having upturned ears, of a bar pro vided with holding spurs and mounted in said ears for longitudinal movement, said bar in one position being free to turn to carry the spurs from operative to inoperative position and in another position being locked from turning movement, said bar having a shoulder, and a resilient locking latch carried by one of the ears and adapted to engage said shoulder and lock the bar from longitudinal movement.

6. The combination with a plate having two upturned ears provided with non-circular apertures, of a bar extending through said apertures and provided with holding spurs, said bar having non-circular portions of a size to fit the apertures and also round portions and being slidable longitudinally in the apertures to bring either the noncircular or the round portions into said apertures whereby when the round portions are in the apertures the bar can be turned to swing the spurs into either operative or inoperative position and when the non-cir cular portion is in the aperture the bar is locked from turning movement, and means to lock the bar with the non-circular portions in the apertures.

In testimony whereof, I have signed my 'name to this specification.

WILLIAM A. BEARD.
