CHARLES W. BAKER, OF PAW PAW, MICHIGAN.
Specification of Letters Patent.
Patented Nov. 10, 1908.
Application filed December 16, 1905. Serial No. 292,015.
To all whom it may concern:
Be it known that I, CHARLES W. BAKER, a citizen of the United States, residing at Paw Paw, in the county of Van Buren and State of Michigan, have invented certain new and useful Improvements in Tackles, of which Furtherobjects, and objects relating to structural details will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which Figure 1 is a side elevation view of my improved tackle. Fig. 2 is an enlarged detail view, showing the arrangement of my improved rope gripping or locking means. Fig. 3 is a detail transverse sectional view taken on a line corresponding to line 3-3 of Fig. 2, looking in the direction of the little arrows at the ends of the section line.
In the drawing, similar letters of reference refer to similar parts throughout the several views.
Referring to the drawing, the pulley blocks A A are preferably provided with tapering side plates and pulleys of varying diameters arranged in series therein as is illustrated in the drawings.
In the structure illustrated A is a running block and A is a fixed block, the load being secured to the running block by means of a suitable rope as G, or otherwise as desired. One end of the tackle rope B is preferably secured to the running block -A, as illustrated, and is thence rove over the sheaves, first over the inner sheaves and thence to the outer sheaves of the blocks, with the hauling end of the rope hanging from the fixed block. On the side of the block A is a laterally projecting fixed jaw a. The face of this jaw is curved transversely to receive the rope,-see Fig. 3.
A pivoted jaw a having a longitudinally curved and toothed or serrated gripping face is pivoted on the side of the block A and arranged to coact with the jaw 64 in gripping the rope,-see Figs. 1 and 2. When the jaw a is in its lower or normal position, the rope may be easily placed between the jaws, when by swinging the pivoted jaw up until it contacts the rope, it will automatically engage the same by allowing a slight backward movement thereof. To release the rope it is only necessary to pull downwardly thereon, which causes the jaw to release and drop to its normal position, against the projecting journal bearing a which serves as a stop therefor; releasing the rope so that it may be manipulated independently of the jaws.
It is evident that the load can be locked or held in any desired position and that the lock can be quickly released and the tackle used independently of the lock, without the necessity of adjusting or looking any parts to prevent their engaging the rope.
I have illustrated and described my improved tackle in the form preferred by me on account of its structural economy and convenience with which it may be used.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a tackle, the combination of a pair of pulley blocks; a tackle rope rove therein;
a laterally-projecting fixed aw having a groove-like engaging face on the outside of the running block; a aw having a longitudinally-curved engaging face with forwardly-projecting teeth pivoted on said running block and arranged to coact with said fixed jaw in grasping the fall end of the rope whereby the fall of the rope may be entirely freed from said jaws or engaged as desired; and a supporting stop for said pivoted aw.
2. In. a tackle, the combination of a pair of pulley blocks; a tackle rope rove therein; a laterally-projecting fixed jaw on the running block; a jaw having a longitudinallycurved engaging face with forwardly-proj ecting teeth pivoted on said running block and arranged to coact with said fixed jaw in grasping the fall end of the rope whereby the fall of the rope may be entirely freed from said jaws or engaged as desired; and a supporting stop for said pivoted jaw.
3. In a tackle, the combination of a pair ning block; a jaw pivoted on said running i of pulley blocks; a, tackle rope rove therein; a laterally-projecting fixed aw having a groove-like engaging face on the outside of the running block; a jaw pivoted on said running block and arranged to coact with said fixed jaw in grasping the fall end of the rope whereby the fall of the rope may be entirely freed from said jaws or engaged; and a supporting stop for said pivoted jaw.
4. In, a tackle, the combination of a pair of pulley blocks; a tackle rope rove therein; a laterally-projecting fixed jaw on the runblock and arranged to coact with said fixed jaw 1n grasping the fallend of the 1'0 e 15 'whereby the fall of the rope may be entire y CHARLES W. BAKER.
