WElGHlNG-SCALE.

SPECIFICATION forming part of Letters Patent No. 357,426, dated February 8, 1887.

Application filed April 22, 1886. Serial No. 199, 846. (No model.)

, and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of weighing-scales in which a weight counterbalances the article weighed 5 and it consists in mechanism whereby the-counterbalancing-weight has an increasing leverage as it is raised, and in dials for indicating and registering the weight, as will be hereinafter fully described, and then specifically claimed.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a floor-scale with registering device attached. Fig. 2 is a side view ofthe top end of the registering device. Fig. 3 is a side view, partly in section, of a portion of the bottom end; and Fig. 4 is a horizontal section on the line X Y, Fig. 3. Fig. 5 is a view of the back side of top end of bracket.

In the drawings, A represents a scale-beam; B, a pendent bracket attached to the frame of the scale 0.

D is a stud projecting from the bracket. E is a sleeve revolving on said stud. On the outer end of this sleeve is a scroll-shaped cam, F. Attached at one end to the scale-beam A and at the other to the sleeve E is a tape, G, and to the cam F is attached one end of the tape H, which is held by the plug h, to the other end of which tape H is attached the weight I. The shaft J, passing through a hearing in the pendent bracket, is provided on its inner end with the wheel K, on the side of which is the stud L. On the outer end of the shaft J is the lever M.

Nis a swinging frame pivoted to the pendent bracket, an arm of which frame carries the roller 70, which engages with the cam K. The

pulling coiled spring a is attached at one end to the frame N and at theother to the pendent bracket B. In the side of this frame N are bearings for the shafts O P Q, and to oneof the sides the stud for the wheel It. The wheel R is attached to a sleeve, 3, on the stud s, and on the same sleeve is the friction gear 8', which engages with the friction-gear S on the sleeve E. The gear R engages with the pinion k on the shaft Q, the pinion on the shaft Q engages with the spur-wheel on the shaft 19, and the pinion p on the shaft 1? engages with the spur-wheel p on the shaft 0. On one end of each of the shafts O P Q are pointers 1 2 3, and on the outer side of the frame, under each of the pointers 1 2 3, is a dial, the one under the pointer on the shaft Q being preferably divided into one hundred equal parts, representing pounds and marks for such fractional parts of a pound as may be desired, and the dial under the pointer on the shaft P is laid off so as to register one on every revolution of the shaft Q, and the dial under the pointer on the end of the shaft 0 to register one on every revolution of the shaft I.

The beam of the scale is held down by the contact of the stud L while the load is being placed on the scale. The cam K is revolved one half-turn, or as much as is necessary to allow the beam to rise by the lever M in the direction indicated by the arrow in Fig. 5. This movement of'the cam allows the roller is, Fig. 2, to rise before releasing the beam A, which brings the frictiongears S and s, by means of the coiled spring a, Fig. 3, in contact before any movement takes place in the beam. The tape G, being wound about once around the sleeve and fastened at the end only, will cause the sleeve to revolve as the beam rises. The tape H, being attached at or near the center of revolution ofthe cam F, would be wound up on the cam-by this revolution of the sleeve, to which the cam is attached, and offer increas ing resistance. It is obvious that the beam will rise until the resistance offered by the weight I is exactly equal to the force actuating the beam, and consequently the sleeve will revolve a distance in proportion to the force actuating the scale beam, which motion is transmitted to the pointers by the friction gearing S and s, and is indicated by the pointers on the dials.

Before the article weighed is removed the cam K should be turned to its original position in the direction indicated by the arrow,

Fig. 2, which will depress the roller k, removing the friction-gearing from contact before the beam shall have been depressed, and the weight allowed to turn the cam and sleeve back to their original positions. The pointers would indicate on the dials the weight of the article thus weighed, and the friction-gears, not being in contact when the cam was allowed to turn back to its original position,will stand at that point, which operation being repeated will carry the pointers forward each time in proportion as the article weighed will raise the weight, thus indicating the weight of any number of drafts until the pointer on the shatt 0 shall have made an entire revolution.

If it is desired to have the weight of each draft indicated separately and not aggregated, the weight would be noted before the beam was depressed by the cam K. In depressing the beam the cam K should be turned in the direction opposite to that indicated by the arrow, Fig. 2, which will not release the contact of the friction-gears, and will cause the pointers to revolve back to their original position.

Havingthus described my invention, what I claim as new, and desire to secure by Letters .tiongears that actuate said registering device,

Patent of the United States, is

1. In a registering-scale, the beam A, the tape G, the revolving sleeve E, the cam F, and the tape H, and the attached weight I, combined and operating substantially as described.

2. In a registering-scale, the combination of 3 5 the beam A, the tape G, the revolving drum E, provided with a counterpoise which shall have increasing resistance as the beam rises, and the friction-gears S and s, and a series of dials arranged to indicate the weight, substantially as shown, and for the purpose specified.

3. In a registeringscale, the combination of a swinging frame pivoted to the bracket B, and carrying the registering device, the fricand the roller It, the friction-gear S, arranged to revolve in proportion tothe load on the scale, the cam K, and stud Ii, arranged to per: mit the contact of the friction-gears before releasing the bcam, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM MORRISON TAYLOR.
