Description
UNITED STATES PATENT OFFICE.
JACOB BALL, OF VVATERLOO, ONTARIO, CANADA.
AUTOMATIC WEIGHING-SCALE.
@PECTFLCATION forming part; of Letters Patent No. 338,654, dated hdarch 23, 1886.
(No model.)
To aZZ whom it may concern.-
Be it known that I, J AOOB BALL, of Waterloo, in the county of Vaterloo, Province of Ontario, and Dominion of Canada, have invented a new and Improved Scales, of which the following is a full, clear, and exact description.
The object of my invention is to provide new and improved scales of simple construction and adapted to be adjusted very easily for weighing bodies of different weights.
The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a front view of my improved scales. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 isadetail sectional view of part of the same, the united weightdisks being raised. Fig. 4 is a crosssectional view of the scale. Fig. 5 is a plan view of one of the weight-disks. Fig. (3 is an edge view of the same.
The scale-casing A is provided in its front with the dial A, over which the pointerB revolves, which is mounted on the shaft 13, journaled in the casing and passed through the casing, and'on which shaft B a pinion, O, is mounted, which engages with a segmental rack, G, projecting downward from the scalebeam D, having knife-edges E near one end, which knifeedges rest in recessed bearings E, secured on the inner surfaces of the sides of the box. A weight, F, is held adjustably on the short arm of the scalebeam D. A rod, G, has its upper end secured to the beam D, and on its lower end one end of a lever, H, rests, which is provided at the opposite end with knife-edge pivots h, resting on bearings h on the inside of the casing. An upright, J, rests upon the lever H, at or near its center, passes up through the top of the casing A, and earries the scale pan, plate, or hopper K on its upper end. A guide-arm, L, secured to the upright J, is pivoted to the inner surface of one end 01' the casing.
From the end of the long arm of the beam D a series of disks, M, are suspended, each having three or more apertnred lugs, N, projecting from the rim, and also three downwardly and outwardly projecting hook-lugs,I, which are passed through the apertured lugs N of the disk M, next below. The disks M can be provided in one or two groupsthat is, they can be suspended from the end of the beam D by means of a single rod, (Z, as shown in Figs. 2 and 3or they may be arranged in two sets and supported from the end of the beam D by means of a cross-bar, d, as shown in Fig. 4. By means of the chain 0 the beam D is connected with the weight P on one end of an arm, Q, the other end of which is secured on a shaft,It, journaled in the casing A, and provided at one end with a crank-handle, S, which can be engaged by a lever, T, pivoted on the side of the casing and having an offset. If desired, a series of weights, 1?, may be connected with the scale-beam.
The operation is as follows: Usually the weight 1? is raised by the crank-handle S and locked in the raised position by thelever T, as shown in dotted lines in Fig. 1. The article to be weighed is placed upon the pan or plate K, and, acting on the lever H by means of the upright J, presses the same down, thereby swinging down the short end of the beam D and raising the long end. The long end ofthe beam raises a series of connected disks, M, until the said disks counterbalance the artiele on the pan or plate K, the weight of the article being shown by the pointer B, which is revolved more or less by the action of the rack O on the pinion O. The number of disks M raised, as shown in Figs. 3 and 4, increases with the weight of the article. In case the article is very heavy,the weight P is released, so that after the beam D has raised all the disks M it can raise the weight or weights P, to counterbalance the article on the pan or plate K.
Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is
1. The combination, with a scale-beam, of the lever H, the rod G, connecting the same with the beam, a pan or plate supported by the lever H, and of balancing-disks M, suspended from the end of the beam D, the weight 1?, and the chain 0, for suspending theweight from the beam D, substantially as herein shown and described.
2. The combination, with a scale-beam, of the lever B, connected with the same, disks hung on one end of the scale-beam, the pan or plate K, supported by the lever H, the shaft R, the arm Q on the same, the weightPon the arm Q, and the chain 0, connecting the beam D and the weight P, substantially as herein shown and described.
3. The combination, with the scale-beam D, of the lever H, a pan or plate supported by the same, the weight P, suspended from the scale-beam, the shaft R, the arm Q, on the end of which the weight is held, and of mechanism for locking the arm Q and its weight P at the desired elevation, substantially as herein shown and described.
4. The combination, with the scalebeam D, 20
S on the end of the shaft R, and the lever T, 2 5
pivoted on the scale-case, substantially as herein shown and described.
JACOB BALL.
