LINEMANS CLIMBER Filed Oct. 25, 1939 /Z M W Patented May 14, 1940 UNITED STATES LINEMANS GLEIBER Joseph A. Klein, Jr., Chicago, Ill., assignor to Mathias .Klein & Sons, Chicago, 111., a. corporation of Illinois Application October 25, 1939, Serial No. 301,185

3 Claims.

My invention relates generally to linemens climbers, and more particularly to improvements in structural features thereof whereby the climber is rendered stronger, and thus more safe, and whereby the straps bywhich it is attached to the wearer may be more readily removed and replaced.

It is thus an object of my invention to provide an improved linemans climber, (sometimes re ferred to as spurs or hooks,) which is strong, although relatively light in weight, which may be conveniently re-gaffed without possibility of injuring the attaching straps, and which may be economically manufactured.

Other objects will appear from the following description, reference being had to the accompanying drawing, in which: I

Figure 1 is a side elevational view of the climber; and,

Figure 2 is a fragmentary sectional view thereof.

As illustrated in the drawing, the climber comprises a leg iron H] which tapers toward its upper end, at which a loop l2 of conventional form is riveted, the loop being provided for attachment of the usual upper strap. A gaff I4 is riveted to the lower'endof the leg iron in in the usual manner adjacent the foot portion N3 of the leg iron. The foot portion l5 terminates in an upwardly and outwardly bent portion l8, which is provided with a pair of outwardly extending lugs 20 and 22, forming between them a notch 24 for receiving a ring 26 The ring 26 is prevented from disengagement fromv the notch 24 by a rivet 28 which extends through suitable holes drilled in the lugs 20 and 22.

The ring 25 serves as a mean for attachment of the ankle strap comprising a portion 30 carrying a buckle 32 and an apertured portion 34, both the portions 30 and 3d being looped about the ring 26 and secured thereto by rivets 36.

The lugs 20, 22 are formed integrally with the leg iron l0, l5, I8, and may thus readily be made sufficiently strong to withstand any unusual strains which may be placed upon them with an adequate degree of safety. Since the forces applied to the ring 26 are in a direction so as to maintain the ring 26 in the bottom of the notch 24, the pin or rivet 28 need merely be strong enough to prevent disengagement of the ring from the notch when the climber is not in use.

The hole for the rivet from the lug 22 has its. lower end slightly countersunk so that the rivet 28 may easily be riveted in place by using a center punch, and may be removed by pounding with a suitable drift pin or similar tool. The facility with which the ring 26 may be removed is of considerable advantage when, as is frequently the case, it is found necessary to re-gaff the climber. In the course of this operation, the leg iron is, of course, heated, and if it were notpossible to remove the ring 26 prior to commencing such operations, the straps 30, 34 might become charred or burnt. Furthermore, whenever it is found necessary to renew the straps, thismay readily be accomplished merely by removing the rivet 28 and replacing the straps and'ring as a unitary assembly, thereafter securing, the rivet 2B in place by spreading the lower end thereof in the countersunk portion of the hole in the lug 22.

While I have shown and described a particular form of my invention, it will be apparent to those skilled in the art that various modifications thereof may be made without departing from the underlying principles of the invention. I therefore desire, by the following claims, to'include Within the scope of my invention all such modified forms thereof by which substantially the results of my invention may be obtained by the utilization of substantially the same or equivalent means.

I claim:

1. In a linemans climber, the combination of a leg iron having a gafi and an upwardly and outwardly extending portion at its lower end, a pair of outwardly extending lugs formed integrally with said portion to provide a ring-receiving notch, a strap-attaching ring fitting in said notch, and a removable securing element extending through said lugs and across said notch to retain saidring therein.

2. In a linemans climber, the combination of foot-supporting portion, a pair of outwardly extending lugs formed integrally with said portion near the end thereof to provide a notch between them, a metallic strap attaching element embraced in said notch, and a removable securing means having a part extending through said lugs and. across said notch to retain said element therein.

3. In a linemans climber, the combination of a leg iron having a gafi-carrying shank and a footsupporting portion, means formed integrally with said foot supporting portion near the end thereof to provide a notch, a metallic strap attaching element extending through said notch, and a removable fastener having a part extending JOSEPH A.
