Description

ENTTED STATES PATENT oEEicE.
J. B. FAYETTE AND D. WHEELER, OF OSVVEGO, NEW YORK.
ST'RAPPING- TACKLE-BLOGKS.
Specification of Letters Patent No. 15,125, dated June 17, 1856.
To all whom t may concern Be it known that we, J. B. FAYETTE and D. VHEELER, of the city and county of Oswego and State of New York, have invented a new, useful and Improved Strap for Tackle-Blocks; and we do hereby declare that the same is described and represented in the following specifications and drawings.
To enable others skilled in the art to make and use our improved strap we will proceed to ydescribe its 4construction and the mode of applying it, referring to the drawings in which the same letters indicate like parts in each of the gures. 1
Figure l, is a plan, and Fig. 2, a section representing the block cut oftI by the side of the strap.
The nature of our invention and improvement in straps for tackle blocks consists in making the strap in two pieces, and providing each part with a hook at one end, to hook into the eye of the block hook, and a hole near the other end for the bolt that fastens them together, so thatl they can be applied to the blocks cold, and. removed from, and applied to other blocks with the greatest facility in a very little time.
In the accompanying drawings A, and B, are the two parts of the 'strap which surround t-he block C; each part being provided with a hook made in the form shown in the drawing, to hook into and connect them to the'eye of the block hook D. The parts A, and B, are made of a uniform width (eX- cept the portions that are rounded to form the hooks) and the ends opposite the hooks which cross the end of the block are reduced in thickness as shown, and perforated for the bolt E, which fastens them together, a recess being cut in the end piece F, for the nut G, as shown; so that by simply unscrewing the bolt- E, the strap may be removed with facility and applied to another block if desired.
It will be apparent that our improved strap may be applied to blocks made of one, or of several pieces of wood, but we think the best blocks are made with two or more parallel pieces of wood, with a rabbet H, across each end to receive the cross pieces F, F, and if the block is to contain more than one sheave, the middle parallel pieces between the sheaves should have a rabbet on both sides at each end to receive the cross pieces and the several parts may be fastened together with screws or rivets as may be preferred before the strap is applied. We have represented this block as provided with metal bushings J, J, fastened in its sides withsteel plates K, K, for the ends of the sheave pin L, to turn against which pin is also made of steel having one or more flat sides in the middle to prevent it from turning in the bushing M, which is cast around it, and riveted to the sheave N, as shown in the drawing.
We will now enumerate some of the advantages of our improved strap to wit. As it is made of a uniform width, the score in the block to which it is fit-ted may be cut quicker and cheaper. It maybe applied to the block cold, so that the labor and expense of heat-ing is saved; besides it does not burn and injure the block like those that are heated and applied hot. A workman can apply the straps to the block after both are completed at the rate of one per minute; and if any part of the block becomes defective the strap may be removed and applied to another with the greatest facility or if the block hook breaks it may be taken off and another substituted for it directly, without removing the rope that runs in the block.
We believe we have described and represented our impro-ved strap for tackle blocks, so as to enable any persons skilled in the art to make and use it, and we will now state what we desire to secure by Letters Patent, to wit. v
We claim for tackle blocks a strap made in two parts, each part having a hook at one end, to hook into the eye of the block hook, and a hole near the other end for the bolt that fastens them together substantially as shown and described.
