Description

' Aug. 29,1944. c. BIENNINGTON DOUBLE GAFF .OR SPUR AS USED ON POLE CLIMBERS Filed May 7, i943 INVENTOR. mom 6% Patented Aug. 29, 1944 DOUBLE; GAFFV a SPUR AS UsEp 0N POLE CHAMBERS Clyde Bennington, Ferndale, Mich. Application May 7, .1943, Serial No. 486,021
1 Claim.
The present invention is designed to improve the spurs on climbing hooks, such hooks as are worn by linemen or tree trimmers working on telephone, telegraph and electric transmission poles, trees, etc.
The purpose of the invention is to so arrange twin points on the spur of the hooks that the secondary, or short point, will provide additional protection to the wearer or user in the event the principal or long point fails. It is to be noted that this secondary point is parallel with the principal point and does not in any manner change the method of using the climbing hooks. Further features and details of the invention will appear from the specification and claim.
A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:
Fig. 1, a side view of the left spur in position on the left climbing hook.
Fig. 2, a front view of the left spur in position on the climbing hook.
Fig. 3, a front view of the right spur in position on the climbing hook.
Fig. 4, a side view of the right spur in position on the climbing hook.
I marks the climbing hooks in Figures 1 to 4 inclusive. The hooks are not a part of my invention and are therefore shown by broken lines only to illustrate the location, arrangement and method of fastening the improved spurs on the climbing hooks. 2, the left spur as a unit. 3, the right spur as a unit. 2-A, long or principal point of the left spur. 2B, short or secondary point on the left spur. 3A, the long or principal point on the right spur. 3-B, the short or secondary point on the right spur. 2-A and 3A, the principal or long points. These are the points in use in normal climbing and arev worn next tov the heel of the foot as illustrated in Figures 2 and 3 but can be worn in reverse order if wearer so desires as they are interchangeable. 2-13 and 3B, the short or secondary points on the right and left spurs. It is to be noted that these points are not in use unless the principal or long points enter thewood an abnormal depth, as for instance, due to soft or decayed places, then the weight is evenly distributed on both points or in the event the principal or long points enter a crack or crevice, chipped or splintered place the short or secondary points because of their oifset will contact solid wood. It is alsoto be noted that the secondary or short points will provide additional safety in a similar manner in the event the lineman or wearer in shifting his position on the pole or tree, as for instance in swinging forward around the pole, cause the principal or long point to be pried loose by the ball or heel of his foot.
The spurs 2 and 3 have a lug or rivet projection 4 which extends through the shank of the hooks by means of which the spur or spurs are fastened or secured to the shank.
Latitude is allowed herein as to details of the twin pointed spurs, that is of changing the angle and length of points on the spurs, as they. may change as circumstances suggest without departing from the spirit of my invention and have said invention remain protected.
Having thus fully described my invention, what I claim as new is:
In a climbing hook or leg iron for a pole climber, a spur formed with twin points disposed side by sideand of different lengths, whereby the shorter point, will serve in case the longer one fails to hold.
CLYDE BENNINGTON.
