j UNITED STATES PATENT OFFICE.
WILLIAM H. BROOK, OF CORONA, ASSIGNOR OF ONE-FOURTH TO JOHN W.
' ALEXANDER, OF NEW YORK, N. Y.
`czHAiN-WRENci-i.
SPECIFICATION forming part of Letters Patent No. 254,862, dated March 14, 188.2. Application filed February 9, 1882. (No model.)
To all whom it may concern.:
Be it known that I, WILLIAM H. BROCK, a citizen ofthe United States, residing in Corona, in the town of Newtown, in the county of Queens, in the State of New York, have invented new and useful Improvements in Chain- Wrenches, the nature of which is fully set forth and illustrated by the following specification and accompanying drawings. 1o The novelty in this myinvention consists in original and peculiar construction of the chain of the wrench, whereby, in providing for a short and frequent adjustment of the chain, the wrench may be effectively used and oper- I5 ated upon bodies of a very small as well as large diameter, and wherein also is found a simple and ingenious method of combination for locking or holding taut the chain.
. Figure 1 is a face or front viewot the wrench,A zo showing the combination for locking the chain.
Fig. 2 is a view in central vertical section of the instrument, at the same time showing its adaptability to objects of small, equally with large, circumference by short adjustment of chain. Figs. 3 and 4 are respectively exterior and interior side views of thejaws, while in Fig. 5 is shown the flat-link chain as ordinarily constructed and in use, and in Fig. 6 the same class of chain as herein devised, also in en- 3o larged view.
IThe chain in this invention is constructed of successive dat links securely fastened together by a rivet which passes `through the ends of each, Figs. 1 and 2. Every alternate link consists of a single tlat piece of metal,m,inserted within two like-shaped parts of the metal, p', which form the succeeding link, sufficiently far to admit passage of the rivet'r. Such a chain then is, as regards its elementary parts, the
4o usual flat-link chain in common use, (oido Fig. 5;) butit differs, however, materially therefrom, not only in the relative `shortness in length of the link and the consequent closer combination of the corresponding parts, but also in the form 4 5 and novel function of the rivet, Fig. 6.
In Fig. 1 may be seen 'the twofold use of the rivet i", which not only serves the usual purpose of binding together the links of the chain, but by its lateral projections is made the ready 5o means of locking the chain, preparatory to the use of the wrench, by pressing the rivet-pendant opposite the receiving-slots h into them.
The method now in use for lookin g a chain of this construction is by insertion of pin through the center point of the middle links; but it is readily apparent, while the chain is weakened thereby, that the distance intervening between the respective centers of two contiguous middle links is nearly quadruple that between any two successive rivets-the agency 6o for fastening chain in my device, (oido Figs. 5 and 6;) for while, as will be observed, in the latter, by reason of the shortening of the links m p of the chain, the end of each side link p is riveted so as to remain almost in contact with the end of the succeeding side link, in the former is left a large space between the ends of the respective side links proportionate to the increased length of the links of the chain.
It will' thus be secn that by means of the 7o shortened links and propinquity to each other of the projecting rivets a short and frequent adjustment of the chain may always be had, (Fig. 1,) and thus render feasible its use in the manipulation of rods and pipes orother bodies having a very small or varying diameter.
It is evident also that the wrench herein described is equally applicable to larger objects, to which all ,previously constructed chain- `wrenches are necessarily limited. 8o
Other important features and devices of the chain-wrench, illustrated by the accompanying drawings, have already been secured to me by United States Letters Patent previously issued for the same.
What I herein claim as my invention, and seek to secure by Letters Patent, is-
1. The combination, in a chain-wrench, with the two detachable serrated double jaws B, with claws j" and lugs k', the bolt G, pin D, 9o and shank A, of a dat-link chain, E, with its links m and p fashioned, located, and riveted, as shown, for short adjustment of chain, and projecting rivets r', for locking the chain, all substantially as and for the purposes as herein 9 5' set forth.
2. The combination, in a chain-wrench, with the jaws B, made with claws f and lugs k', the bolt C, pin D, and shank A,ot' a hat-link chain,
E, with its rivets i", projecting laterally for Ioo locking the chain, substantially as herein described. y
