IMPROVEMENT IN SPRING-BALANCES.
Specification forming part of LettersPatent No. 17 1.650, dated January 4, 1876; application filed November 10, 1875.
To all whom it may concern:
Be it known that I, JOHN P. OHATILLON, of New York 'city, in the county and State of New York, have invented a new and Improved Spring-Balance, of which the following is a balance adapted to heavy weights; and the invention consists, principally, in placing the index-bearing runner in front of the spring, so as thereby to allow the use of a short case, and in other details of improvement, hereinafter more fully pointed out.
In the accompanying drawing, the letter A represents the case or shell of my improved spring-balance. B is the spring, suspended from a bolt, 0., that is fitted through the top of the case or shell. The lower end of the spring B connects with a plate or slide,
' O, to which the hook D, which receives the articles to be weighed, is secured. The length of the case exceeds but little that of the spring, as shown. This is made possible by attaching the lower end of the runner E to the plate 0, so that the body of said runner will be in front of the spring, and behind the slotted face-plate F of the case or shell. The index 12 is fastened to the upper end of said This arrangement is in contradistinction to the usual method of extending the runner downward from the slide (3, which requires a corresponding downward extension of the case or shell. The face-plate F of the case or shell has a vertical slot, through which the shank d of the pointer 1) passes, and wherein the same is allowed to move up and down in conformity with the motions of the spring. The shank d of the pointer is made in form of a block, of nearly the same width as the slot, so it will serve as a proper guide to pre- Vent the spring from twisting laterally during operation. The lower end of the slot constitutes the stop for the downward motion, and the consequent limit of expansion of the spring.
In order to bring the body of the face-plate F as near as possible to the spring, I prefer to form a groove or recess in the back of said plate F for the reception of the runner. Were it not for this recess the shell A would have to be larger transversely,to admit the runner between the spring and the plate F. The recess formed in the plate F is open at the bottom, to permit the downward movement of the runner.
The graduated scale 0 is marked on the plate F along the slot, as shown in Fig. 1.
The plate F is fastened to the case A by obliquely-placed bolts f f. (Shown in Fig. 5.) These bolts, by their position, effect their purpose better than if placed at right angles, and I use, therefore, fewer bolts than would other wise be necessary. For the reception of these. bolts I form triangular lugs g g on the edges of the case A, as shown in Fig. 5, which lugs, by virtue of their form, are much stronger than the flanges heretofore formed on the shells of spring-balances. On the inner side of the plate F are a series of projecting blocks, h h, in such position that they will be in line transversely with the several lugs g, and bear against the inner faces of the shell A. They serve thus as inner braces and abutments for the shell, and, in part, also as guides for the bolts ff. M are other blocks projecting from the inner side of the plate F into notches in the edges of the case A, as indicated in Fig. 2. They hold the plate F in proper position vertically, serving also as verticalbraces for the entire case or shell. j is a ledge affixed to the face ofthe plate F, to surround the part bearing the slot for the pointer and the indexplate. This ledge is to protect the pointer and index-plate against injury.
I claim as my invention- 1. The combination of the case A with the spring B, upwardly-projecting runner E, slotted face-plate F, and pointer b, all arranged so that the runnerE is between the spring and face-plate, and the pointer 11 on the outer face of the face-plate, substantially as specified.
2. The combination of the pointer b with projecting i e j, which embraces the slot the block and guide (1 and upwardly-projectand index-plate, substantially as herein shown ing runner E, substantially as herein shown and described.
and described. JOHN P. GHATILLON.
3. The combination of the face plate F, Witnesses: which is slotted for the reception of the point- ERNEST G. WEBB,
er b, and carries the index-plate a, with the A. MORAGA.
