ICE CREEPER Filed March 30, 1939 Patented Dec. 5, 1939 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to an ice creeper for attachment adapted for use on overshoes primarily, to aord traction and prevent slipping when walking on ice.

A particular object is to provide such a construction as is substantially embedded in the sole of the overshoe, practically out of sight, which is light in weight, durable and eihcient and capable of being adjusted so that its spurs will either be projected or retracted as preferred.

The more specic objects and advantages will become apparent from a consideration of the description following taken in connection with the accompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a fragmentary bottom view of an overshoe equipped with my improvement;

Figure 2 is a side elevation of the parts of Figure l;

Figure 3 is a vertical sectional view taken on the line 3 3 I'of Figure 2;

Figure 4 is a detail section showing the projected and retracted positions of the spurs;

Figure 5 is a plan View of the device alone, and

Figure 6 is an elevation of the traction element alone.

Referring specically to the drawing wherein like reference characters .designate like or similar parts, the invention is shown for example in connection with an overshoe generally designated I0 and being of any suitable material, for instance rubber and rubberized fabric construction. Such illustration is to be taken as but one example of an article in connection with which the invention may be used, since it may be applied, where practical, to all articles likely to be worn on a foot or a shoe. Said overshoe I I! includes the usual sole II.

Embedded in the sole II and disposed transversely thereof is a metallic mounting plate I2, preferably of relatively light weight in view of numerous perforations I3 therethrough. Such plate adjacent its outer portion is widened as at I4 and then formed into an upstanding wall I5, terminating in an outwardly projecting ange I6. It will be noted, particularly from Figures 2 and 3, that the wall I5 is disposed in the sole II relatively close to a marginal edge thereof and that it projects through the latter at the ridge I 2, where the upper is cemented to the sole. The

n ilange I6 extends outwardly relatively close to said ridge.

Said plate I2 mounts a traction element generally designated I1. Such traction element I1 has a rod portion I8 disposed longitudinally of the plate I2 and journaled in bearings I9 of such plate, preferably being struck out portions bent over the rod I 8. Rod I8 has depending spurs 29 operable in slots 2| of the plate I2, and clear- 5 ance recesses 22 provided in the sole Il, below the slots and plate. Such spurs are adapted to be projected to the full line position shown in Figures 2, 3, 4 and 6 to afford traction to the wearer or when traction is not desired, they may be 10 moved ino the dotted line position shown in Figures 2 and 4, being thus retracted above the sole or walking surface. The spurs preferably have an angular portion 23, which in projected position as shown in Figure 4, will abut the plate 15 I2 at one edge of the adjacent slot ZI to enhance its support.

In order to secure the traction member in either projected or retracted position, it is provided with an operating arm 24 of resilient mate- 20 rial. Cooperating with the arm 24 is a pair of

notches

25 and 26 provided in the outer edge of the flange I5. The resilience of arm 24 urges the same into engagement with the

notches

25 and 26 when in registry therewith and when en- 25 gaged with the former, the spurs will be retracted and when engaged with the latter, the spurs will be projected. It will be realized, that in moving the arm 24 from one notch to the other, that the same must be sprung slightly to disengage the 30 adjacent notch, but will through its resilience snap into a notch when registered therewith.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim asl my inventionl. A shoe article of the class described having a plate embedded in a sole, a wall on said plate extending upwardly and outwardly primarily located within the sole, and a traction member 40 mounted on the plate for movement to and from projected position, and coacting means between the traction member and wall to secure the traction means in its different positions. v

2. A shoe device of the class described having 45 a plate embedded in its sole, a` wall on said plate within the sole extending upwardly adjacent one margin of the sole, a flange extending outwardly from said wall and exteriorly of the sole, a traction member pivoted on said plate, said traction 50 member having spurs extending therefrom and through the plate, and an operating means for the traction member having latch engagement with said flange.

3. A shoe device of the class described having 55 a plate embedded in its sole, a Wall on said plate within the sole extending upwardly adjacent one margin of the sole, a ange extending outwardly from said Wall and exteriorly of the sole, la traction member pivoted on said plate, said traction member having spurs extending therefrom and through the plate, and an operating means for the traction member having latch engagement With said ange, consisting of a resilient arm on the traction member and notches in said flange into Which the arm is adapted to snap.

4. A shoe device of the class described having a plate embedded in its sole, a Wall on said plate Within the sole extending upwardly adjacent one margin of the sole, a flange extending outwardly from said Wall and exteriorly of the sole, a traction member pvoted on said plate, said traction member having spurs extending therefrom and through the plate, and an operating means for the traction member having latch engagement with said flange, consisting of a resilient arm on the traction member and notches in said flange into which the arm is adapted to snap, said plate having notches through which the spurs extend, said spurs having angular portions to eieot engagement of the spurs in projected position with a Wall of the plate for reinforcement.
