ANTISLIPPING ATTACHMENT FOR GRUTCHES AND CANES.

Application filed March 18, 1919.

T 0 all whom it may concern:

Be it known that I, ANTHONY LANSKY, Jr., a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Antislipping Attachments for crutches and Canes, of which the following is a specification.

The present invention relates to anti-slipping attachments for crutches or canes, and has for an object to provide such a device which will be efficient to prevent slipping and can be easily placed in operative and inoperative position, will be rigid and substantial in construction and may be readily attached to any of the ordinary forms of crutches or cane-s.

A further object is to provide such a device which will be adjustable relatively to the end of the cane or crutch, will be inconspicuous and will be free of any parts that will readily get out of order.

lVith these and other objects in view, an embodiment of my invention is shown in the accompanying drawings and this embodiment will be more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In the accompanying drawings:

Figure 1 is a front elevation showing the end of a crutch or cane with one embodiment of my invention in place thereon,- and in inoperative position;

Fig. 2 is aside elevation thereof;

Fig. 3 is a side elevation, showing the device in operative position;

Fig. 4 is a perspective view of one portion of the device which may be called the antislipping member;

Fig. 5 is a perspective view of another portion of the device which may be called the supporting membe Fig. 6 is a fragmentary perspective view of a modified form of anti-slipping member.

Similar reference characters indicate corresponding parts throughout the several fig ures of the drawings.

Referring to the drawings, the embodi-.

ment of my invention shown therein comprises an elongated metal strip or plate 10, provided with projecting and opposed lug portions 11 and 12 at its upper end and 13 i and 14 along its side edges and spaced from its lower end. This plate is secured lengthwise of the end portion of the cane or crutch Specification of Letters Patent.

Serial No. 283,288.

15, and above the lower rubber tipped end 16 thereof, by means of cross pieces 17 and 18, provided respectively with bolts 19, 20 and 21, 22, having their heads countersunk in the outer side of the said cross pieces and screwed into the threaded holes 23 of the said lugs to tightly clamp the plate to the crutch or cane.

Projecting from the face of the plate 10 there are provided in spaced relation, a pair of screws 24.- and 25, and above and below the same and equally spaced from the said screws there are provided a pair of supporting pins 26 and 27. The member 10 with its associated parts may be called the supporting means.

The antislipping member consists of an elongated plate or strip 28, rounded at one end as at 12$). and provided at the other end with an antislipping edge, 30, which may be of any suitable form, that is it may be knife edged, tapered or as shown in Fig. (3, it ma y be serrated as at 31.

Adjacent the rounded end 29 there is pro.

vided lengthwise of the strip a group of three openings, 32, 33, 3-1 spaced from each other a distance corresponding to the spec ing of the screw 2-1: from the pin 26; An other group of openings, 35, 36, 37 similarly spaced and removed from the antislipping end is provided in the strip 28, the central opening 36 being spaced from the end opening 3% of the other group, a distance corresponding to the distance between the screws 2 and 25. The antislipping member is securedto the supporting plate 10 by engaging the openings with the screws and pins 24, 25 and 26, 27 and retaining the same by means of winged nuts 38 and 39, engaging the screws 2% and 25 which, for this purpose project beyond the outer surface of the plate 28, while the pins 26 and 27 when engaged with the said plate are flush with the outer surface thereof.

In the inoperative position of the device, the end 30 of the members 28 is uppermost as shown in Figs. 1 and 2, the rounded end 29 being spaced from the tip of the cane or crutch. In order to make the same operative, the winged nuts are disengaged and the plate is reversed in position, so that the openings 32 and 33 are engaged with the pin 27 and the screw 25. while the openings 35 and 36 are engaged with the screw 2-1 and the pin 26. as shown in Fig. Tn this position the antislipping end projects slightly below the rubber tip, so that it engages the ground. Crutches are usually used at an angle and in order to accommodate this and allow of deflectionof the rubber tip, the antislipping end may be placed at any desired relation to the rubber tip, either by changing the. position of the supporting vmeans or by means of the adjustment afforded by the openings in the plate 28. In Walking upon ice or snow the antislipping end Will preferably project more than when using the device upon the \vet. pavement, and in the former case, a member having a ser rated end such as 31 is most advantageously employed.

The attachment is simple and efficient in operation, is absolutely rigid so that it Will have a firm hold upon the ground, is inconspicuous and free of projecting parts which might interfere With ivalkin'g, and may be readilyattached to any of the ordinary forms of crutches or "canes The antislipping end may be sharpened With aiiile or the like, when this is needed. a g p I have illustrated and described preferred and satisfactory improvements of my invention, but it is obvious that changes may be made therein Within the spirit and scope thereof, as defined in the appended claims.

I claim: a I x 1. An antislipping. attachment for crutches or canes having aground engaging end, comprising a supporting member, an antislipping member having aground engaging end, and a non-ground engaging end, and means for securing said anti slipping member to said supporting member With the ground engaging end tended therefrom in one direction and for reversibly securing said antislippinglmeiir ber to said supporting member With the Copies of this patent may be obtained for non-ground {engaging end removed from gI OLIIICI.

2. An antislipping attachment for crutches or canes, comprising supporting supportingmember and the end of the cane,

said attachment means adapted to permit the securing of said ant'isli'pping member to said supporting member with the ground gripping end projected beyond the end of said crutch 0r cane and reversible with said ground gripping end removed from the end of said crutch or cane.

3. In combination, a crutch or cane having a ground engaging end, and an antislipping attachment therefor comprising a supporting member, clamping means adapted to secure said supporting member to the end of said crutch or -cane, an antislipping member having a ground engag ing end and a non-ground en aging end, and means to'secure's'ald antishppmg 1116111- ber to said supporting member With the ground engaging end extending therefrom in one direction, and to reversibly secure said antislipping member to said supporting member With the non-ground engaging end removed from "the ground. r Y

In testimony that I claim the foregoing as my invention, I have signed my name hereunder. I
