IITTOHNEV "responding parts in EDWARD w. MARVIN, or BROOKLYN, new YonK, "BnooKL rn, nnw
[0 aZZ'w/tomit may concern: a j Be it known that I, ED ARD "WM MARVIN,
a cit zen of the United States, and a resident of Brooklyn, county of; Kings, and-,State of and, in Draft- Hooks, of
have invented certain new useful Improvements which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
ly invention relates to draft hooks and it has for its object to provide a device of this character that shall be simple and durable in construction and adaptedto support a load many times greater than that which can be sustained by devices of the same size and general character hitherto constructed.
I will describe my lowing specification and point out the novel features thereof in appended claims.
igures 1 and 2 are elevations at right angles to each other of a combined hook and sheave block which is constructed in accordance with my invention, the hooks being open in Fig. l and closed in Fig. 2.
Like characters of reference designate corall the figures. eferring to Figs. 1 and 2 of the drawthe structure hook in the form of a metal clevis 35 which is the supporting member. One of the ends of this clevis forms an engaging arm 36. Its other end terminates in a laterally tending comprises another hook to the clevis. A sheave or pulley 39 may be supported between \the arms of the clevis, and if desired a sheave block 40 may be provided which covers the clevis and partially incloses the sheave.
he sheave is pivotally mounted on a bolt 41 which extends laterally through the arms of the clevis and the sheave block as shown in Fig. l. The sheave block comprises a pair of oval side members pair of end spacing blocks side block 43 is divided and is secured to a projection 47 The upper end of the vided with a hole 48 w ceive the projection 37 jection being provided ceive a cotterpin or wedge in order to hold the hook and clevis closed.
When the hook is open as shown in Fig. 1
member 38 pivoted 44 and 45. The its lower end 46 of the hook 38. projection 47 is prohich is adapted to reof the clevis, the prolnvention in the fol,
42 and 43 and a 49 to rea r Fhlhtllth Assmnfon TO J. roan.

together of the hook areswung a rope or cable to be the sheave block. After the rope een inserted and the hook N f the block with the projection 47 outwardly, permitting inserted in .asb
the lowe r jend a;
hooks may be adapted to receive a sheave block and sheave as shown in the drawings, or they may be similar to each other.
ariations in size and arrangement of parts may be eifected within the spirit and scope of my invention.
What I claim is l. The combination with a sheaveblock projection at one end and a laterally projecting lug at the other and a sheave rotatably mounted between the arms of the U-shaped frame, of a hook pivotally connected to the supporting member having a perforated projection adapted to receive the lug of the frame when the hook the hook and the end of the supporting projection of th adapted to interlock whereby the supporting member the load pivotal connection.
2. The combination witha sheave block comprising a U-shaped frame having a hook supporting member with jection at one end and a laterally pro ecting hooks arranged on opposite sides of their connecting pivot, each having a rigid sup- Gopiee' of this patent may be obtained for five cents each, by addressing the porting pro ection adapted to interlock with the end of the other hook, one of the hooks 15 being provided with a sheave block and sheave, the supporting projection of the other being adapted to close the sheave block.
In witness whereof, I have hereunto set 20 21st day of EDWARD W. MARVIN.
