LINEMANFS BELT Filed April 3, 1929 AlberiA. Jirauws Patented 21, 1931 ama PATENT oFFi-c E ALBERT STRAUSS, PITTSBURGH, PENNSYLVANIA LINEMANS BELT Application filed April 3,
This invention relates to linemans pole straps, window washers safety belts and the like.
, The pole straps used by linemen ordii narily consist of a strap of leather or the like having a snap hook. at one end for attachment to one side of the linemans body belt and an adjustable loop at the other end carrying a snap hook for attachment to the other side of the linemans body belt. The loop adjustment is quite commonly made by means of an ordinary tongue provided buckle carried by the extremity of the belt and sliding on the strap between the two snap hooks, the portion of the strap on which the buckle slides being provided with suitable eyes for the tongue or tongues of the buckle. The strap is of course passed through asuitable loop on the second snap hook so that a loop is provided in the strap itself. There are two principal points of wear in such pole straps and one of these is at the point where the strap passes through the loop of the second snap hook.
The other is at the point where the tongue or tongues pass through the eyes. In addition, such straps also Wear at their central part where they pass around the pole in use. Obviously, breaking of the strap at any one of these pointswill tend to cause the linemanto fall. In like manner where such straps are used in window washing they are apt to break at the first two points and cause injury to the'user.
The principal objects of the present invention are to provide'an improved device of this character whereby breakageof the 7 main strapinember brings into service an auxiliary or safety member; to provide an auxiliary or safety strap member in such a device which under normal conditions of 1929. Serial No. 352,269.
lVith the above and other objects in view as will be hereina ter apparent, the invention will now be particularly described and claimed, referencebeing had to theaccompanying drawings, wherein Figure 1 is a perspective view showing a lineman using the improved pole strap.
Figure 2 is a detail perspective view of the loop end of the pole strap illustrated in Figure 1. r s
Figure 3' is a perspective view showing the action of the safety member upon breakage of the-main member of the strap.
Figure 4 is a plan view of a modified form of the strap in use. v p a Inthe invention as here illustrated there is] shown the usual polestrap consisting of a leather or other main strap member 10 7 having one end passed through the loop ll of a snaphook 12 and doubled back on the main part of the strap and'secured as, by riveting, sewing or any other suitable means. The other end portion of the belt 10 is passed throughthe loop 13' of a snap hook 141 and connected to this end is shown an ordinary two tongue buckle 15 which is thus .slidably mounted on the portion of the strap 10 between the two snap hooks and adjacent theloop 13. Eyes 16 are provided for the tongues of this buckle so that an adjustable loop 17 is formed at this end of the strap by means of which the dislance between the snap h ooks along the strap may be regulated at thew'ill of the user. This buckle 15 is preferably of greater dimensions than the opening in the loop 13 so that the buckle cannot pass through this loop.
In connection with the main strap there is provided a safety strap shown in Figures 1 and 2 at 1 8 and this safety strap has one end riveted or otherwisesuitablysecured to the outside of the main strap as indicated at'19. The strap 18 passes through the loop 13 on the outer side of the strap 10 and has its remaining end fixed to the outside of the strap 10'at a'point beyondthe'end of the series of'eyes 16 as at the'point 20.
In the form shown in Figure ithe con- 'structioii" is the same except that'the strap 18 in this case is of sufficient length to pass entirely around the pole when used by a lineman, the attachment point 20 thus being close to the snap hook 12.
In each of these cases it is to be noted that the strap 18 is of greater length than the length of the strap between the attachment points of the strap 18. By this means the strap 18 is normally slack and no stress is brought on the stra under normal conditions of use so that the strap remains free from wear at all times. If, however, the main straplO wears sufficiently at one of its wear points to break or breaks at any place from any cause then the strap 18 comes into play, the buckle being pulled against the loop 13 as shown in Figure 3, and the new and unworn strap 18 takes the stress previousl taken l3 the strap 10. It
will be noted tiat the points at which the strap 18 is attached to the strap 10 are points beyond which there is no wear under ordinary circumstances on the strap 10.
Having thus described the invention, what is claimed as new, is:
1. A linemans belt comprising in combination with a body belt, a main strap member for encircling a post or the like having adjusting means intermediate its ends, and a safety member secured to the main member on opposite sides of the adjusting means and extending across the adjusting means.
2. A linemans belt having in combination with a body belt, a main strap member provided at one end with means to sesure said end to one end of the body belt, a buckle slidably mounted on the main mem ber adjacent the remaining end, the end portion of the main member adjacent thai whercon the buckle slides being doubled on itself and having its extremity secured to the buckle whereby to form a loop in said. member, means slidably mounted on the loop to secure the said main strap member to the other end of said body belt, and a safety strap member extending across the buckle and having one end connected to the main member at one side of the buckle and the other end connected to the main member at the other side of the ouckle.
3. A linemans belt having a main strap member, a snap hook secured to one end of said main member, a second snap hook having a loop wherethrough the main member passes, a buckle carried by the remaining end of said main member and slidable on said member between the snap hooks, said buckle forming a stop to prevent the belt end pulling through the loop, and a safety member consisting of a strap having one end fixed to the main member between the buckle and the first snap hook and its other end passed through the loop and fixed to the main member adjacent the buckle.
4. A linemans belt having a main strap member, a snap hook secured to one end of said main member, a second snap hook having a loop wherethrough the main member passes, a buckle carried by the remaining end of said main member and slidable on said member between the snap hooks, said loop forming a stop to prevent the belt end pulling through the loop, and a safety member consisting of a strap having one end fixed to the main member between the buckle and the first snap hook and its other end passed through the loop and fixed to the main member adjacent the buckle, said safety member being of greater length than the length of the main member between the points of attachment of the safety member whereby the safety member is unstressed under normal conditions of use of the pole strap.
