COUNTER-SCALE.

SPECIFICATION forming part of Letters Patent No. 277,878, dated May 22, 1883,

Application filed May4,18Rl. Renewed February 23,1883. (Nomodch) .'Z 0 till whom it may concern Be it known that I, DENNIS BUOY, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvementsin Scale Bealnsand Weights; and I do hereby 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 letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to beams and weights especially designed for use with counter-scales, though capable of application to other kinds of balances.

Thenatureofsaid invention consists, chiefly, in thecombination, with a trough-sh aped beam provided with slot-s or notches, or both, of a weight which has a shank that lies within said trough, and one or more project-ions or extensions adapted to set into said notches or slots.

It consists, further,in the combination,with the above, of one or more supplementary beams adapted to sustain ahangingweightor weights, and in certain peculiarities of construction hereinafter particularly set forth.

In the accompanying drawings, Figure 1 represents a perspective view of a counterscale embodying my invention. Fig. 2 represents a plan view of the beam detached. Fig. 3 represents a detail perspective view of the detachable weight, and Fig. 4 represents modification of the latter.

A designates the base of the scale; A, a bifurcated standard erected on one end thereof B, the scale-beam, pivoted by gudgeons b b in the upper ends of said bifurcations; G, a detachable frame hung on pins or studs extending laterally from the short arm of said beam, and I) a bowl or receptacle supported onsaid frame and detachable therefrom. The scale-beam B is in the form of a trough with its hollow face upward. Its sides are provided at regular intervalswith notches B, and its bottom. is provided with openings B also arrangedatregularintervals. Eitherthenotches or the openings may, however, be dispensed with, though the former insure more delicate and reliable measurement.

E designates the weight which I employ, and which consists of a long heavy shank or body,E,which lies in the trough of the beam,

a neck, 0, curved slightly upward, ahead pro- .\-'ided on the under side with a broad fourface wedge or point, E and a handle, E for lifting and moving it.

In the modification shown in Fig.4 the point is dispensed with, and cylindrical laterallyextending studs 'or gudgeons E are used instead.

It the beam B is provided with openings B and not with notches B, that form of weight is used which has the point E". If the beam is provided with notches and not with openings, the weight is of the form shown in Fig. 4. In the former case the point sinks down into any one of the openings over which it is brought, and holds the weight firmly in place by its wedge-like action. In the latter case the studs or gudgeons E sink into the corresponding notches, B, in the side flanges of the beam B. In either case the weighing is effected by taking hold of handle E lifting the head of the weight out of engagement with the beam, moving the said weight forward or backward far enough tojust balance the commodity in the bowl or receptacle before mentioned, and then dropping the point or gudgeons into engagement with another hole or pair of notches. The cylindrical shape of the studs or gudgeons E insures their being firmly seated in the notches. Other forms might be substituted without departing from the spirit of my invention but the results would be less perfect, as the studs would be in some danger of catching unduly on one side or the other of the notches.

The weight can be lifted out ofthe beam at any time for inspection or cleaning of either device; but the long and heavy shank E, which nearly fills the interior of thetrough, prevents accidental separation.

To allow greater delicacy in weighing, I attach to the side of the main beam above de scribed aparallel supplementary beam, F,which is notched on its upper edge, and provided with a hanging weight, G. If the main beam weighs pounds, the supplementary beam may be used to weigh ounces. Of course other supplementary beams may be used for still greater delicacy ofweighing, each beam being appro- ICU priately marked with figures in the usual manner. The other end of the beam is preferably provided with a sliding cap, 11, which is slotted at h, and held to the beam adjustably by a screw, H, so as to afford a ready means of regulatingthe balance of the beam and compensate for changes of leverage due to increase or diminution of temperature or to any other cause.

Any suitable material may be used in the construction of these scales, and they may be made of any size desired.

I am aware that trough-shaped beams are not broadly new; also,that weights have been set into the same. I do not broadly claim such construction and combination. My weightlias a shank which extends longitudinally in the beam, parallel thereto,and said shank will hold it in place much more reliably than a mere block or vertical shank extending down from the weight into the trough. Therefore,

Having thus fully descrbed my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a trough -shaped scale-beam, a detachable weight provided with a shank that extends longitudinally in said trough and parallel to said beam, substantially as and for the purpose set forth.

2. In combination with a trough-shaped scalebeam having notches or openings, a weight having a shank that lies in said trough, and a head provided with a point or studs which set into said openings or notches, substantially as and for the purpose set forth.

3. In combination with a trough-shaped scale-beam having notches in its side flanges or walls, a weight provided with a shank which lies in said trough, a pair ot cylindrical studs that set into said notches, and a handle whereby the head of the weight can be lifted and moved backward and forward in weighing, substantially as and for the purpose set forth.

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

DENNIS J5 UOY.
