SPAR TREE STRAP AND ADJUSTABLE CLAMP EYE THEREFOR 1 Filed March 12, 1935 R Brown EH'el Fig. 6.

UNITED STATES PATENT OFFICE SPAR-TREE STRAP AND ADJUSTABLE CLAMP-EYE THEREFOR Eitel P. Brown, Little Rock, Wash., assignor of one-half to Roy Wood, Bordeaux, Wash.

Application March 12, 1935, Serial N0. 10,650

1 Claim.

This invention relates especially to the short piece of cable, commonly known as the strap, which is wound around the top of a spar tree in the logging industry, and to which the various 5 cables, blocks, or other apparatus may be attached, and by which said apparatus is secured in position on the spar tree.

The logging industry, of necessity, requires the use of much apparatus removed at a considerable distance from the camp or other source of supplies, and, therefore, it is of great interest to the industry to reduce the number of parts which may have to be transported to the scenes of operations. It has been the practice to provide a short piece of cable, commonly known as a strap, to

pass around the spar tree, in order to provide a means of attaching other apparatus to the tree. As the logging operations progress, it is necessary to move the apparatus from one spar tree to another. These spar trees will vary very considerable in size, and, therefore, it has been the practice to provide straps of different lengths, each adapted for use on different sized trees, thus necessitating the transportation of a number of such straps from place to place as the operations progress.

It is an object of my invention to provide a single such strap to take the place of the several now used, thereby reducing the original expense and the expense of transporting a large number of straps as at present. Another object of my in-' vention, is to form the clamp-eye in such a manner that it can not become disengaged while in use, and, also, in such a manner that it may be 5 tightened up very securely before it is used, and

can be quickly released without in any way damaging the parts. Another object is to provide means whereby the several parts may be kept together thereby preventing the loss of some of 40 the parts when not in use.

I accomplish these objects by providing a piece of cable which is sufficiently long to be used on any tree, and which is provided at one end with an ordinary socket eye permanently attached thereto, and at the other end with a stop,

or other device to hold the parts on the cable when not in use, and my improved clamp-eye adjustably mounted between the two ends. This adjustable clamp is constructed so as to be firmly clamped in any position on the strap cable and includes an eye or closed ring. The portion of the strap between the fixed eye and the clamp-eye is the portion which is used to pass around the spar tree.

other objects is illustrated in the accompanying drawing, in which Fig. 1 is a perspective view of a spar tree, showing my improved strap in use thereon; Fig. 2 is a similar view of a portion of the spar tree, drawn to a larger scale, and illustrating my invention in use; Fig. 3 is a side elevation of my improved clamp-eye,,showing the parts disengaged from each other before being placed in use; Fig. 4 is a side elevation of the improved adjustable clampeye assembled and ready for use; Fig. 5 is a section thereof, taken on the line 5-5 in Fig. 4, parts thereof being shown in section to illustrate the construction thereof; and Fig. 6 is a plan view of one of the clamp pieces.

Similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, it will be seen that the strap is formed of a piece of cable I, to one end of which is securely fastened a permanent socket-eye 2, and to the other end of which is secured a suitable stop 3. The cable I is threaded through the main body of my improved clampeye and through the nut 4. In assembling the strap first the fixed socket-eye 2 is mounted at one end, then the nut 4 is threaded on the other end, the cable being passed through the hole in the said nut, then the main body of the clampeye follows the nut 4 in such position that it:

eye end is furthest removed from the said fixec' eye 2, and then the stop 3 is secured to the end of the strap to prevent the nut and the clam from sliding of! the strap when not in use.

The main body of the clamp comprises a heav: socket 5, having a conical hole 6 extending longitudinally through it, through which the salt cable i is threaded, and is provided with an eye extension I, to one side of and in front of th' said main socket. The above-mentioned hole has its larger end at the front of the said socket and its smaller end adjacent the nut 4. Thi hole 6 is large enough at its smallest end to permi the ends of the clamp pieces to pass freely there through.

Two clamping pieces 8 and 9 are provider which together form a split clamping cone, shape to the same degree of taper as the hole 6 an adapted to fit in the said hole. The central fie surfaces ill of the split cone have been planed 0: so that each piece is of less thickness than th radius of curvature of the cone, thereby permit ting the clamping action between the parts 8 an 9 as the cone is drawn into the conical hole 6 i the main socket body. The flat inner sides to these two clamping pieces are provided wit necessary to place the twqclarnpirig q 8 in the desired position oiithe esb1e-msnspins i.

il endsllextefid dut rreiir' me smallerie thereof,

grooves l I adapted to fit on the said cable I. One of these clamping pieces 8 is provided with four pins l2, extending out from the flat surface I II, and the other piece 8 is provided with complementary holes. in its surface, adapted to receive the pins l2, above described. The small ends 14 ofz the clamping pieces v-8 v are, deeply screwvthreadedg aiidgjtaken togethe for h a screw :1: onto which the nut 4 may be screwed: The pins l2 and the holes i3 insure the proper alinementof ds of thenut'" the pieces 8 and 9 so that the three 4 will properly engage the threads """the ends ll; thereof.

In assembling my improyedpdjustable, clanip in proper position on the strepcabl fie ce '8 n I2 entering the holes I!) and then slide-the bodyof the socketjthereover, until the threaded to loosen the grip of the clamping pieces I and I on the cable I, and thereby permitting the clampeye to slide on the said strap to its new adjusted position thereon.

Thus it will be seen that I have provided a single strap which may be applied to any spar H tree, yvithin its capacity, thereby eliminating the QY FEZP 19 al be seen thatythepi 5min: once been assembled on'the strap. need never be removed therefrom and, therefore, the danger of of the-seyeral parts is removed.
