COUNTING ATTACHMENT FOR SCALES Original Filed Jan. 25, 1948 Ressued Dec. 9, 1952 UNITED STATES PATENT OFFICE Original No. 2,524,202, dated October 3, 1950, Se-

Claims.

The invention relates to new and useful improvements in scales but more particularly to scale beams having an ausiiiary of parallel beams arranged in co-operative position with the sliding poise, and more particularly to a device of this kind which may be attached to a conventional scale beam in position to co-operate therewith and has for its objects the provision of a device of this character which is simple of construction, economica1 to manufacture, highly eiicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. This invention will be best understood by reference to the accompanying drawing forming a part of this specilication and in which:

Figure 1 is a side elevation ci" a platform scale head equipped with an attachment embodying the invention in position for use;

Figure 2 is a plane view taken on the line Zw-ZE of Figure l;

Figure 3 is a perspective View of the device apart from the conventional scale beam; and

Figure 4 is a perspective view of an adjustable beam arm.

A practical embodiment of the invention in the drawings comprises the head l5 of a platform scale mounted at the top of conventional steelyard housing It. A fulcrum bearing il is attached to the upper part of the steelyard housing I6 and below the head l5 in position to operatively receive a knife-edge pivot E53 attached to a conventional scale beam I intermediate its ends. A sliding poise 2l) is arranged on the beam I9 and carries a clamping screw 2i which serves the purpose of holding the said poise it in a selected position on said beam i9.

A balance ball 22 is adjustably carried by a threaded lshaft 23 at the inner end ci the beam I3 which is of a conventional type and serves the purpose of settingthe beam l0 in balanced relation, as will be readily understood.. Arranged below the balance ball 22 and attached to the beam I9 is load pivot 24 from which is suspended a bearing loop 25 which in turn supports a steelyard rod 23 by a hooked end 2l thereof.

The outer end of the beam I9 is projected through a slotted guard frame 23 provided with a beam latch 32 for hol-ding the said beam I9 in inoperative position, and a counterpoise loop 29, hung from a tip pivot 3b, from which is suspended a scoop holder 3l.

The bea-m i9 is further provided at its inner end with an auxiliary unit 33 having a centrally Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

placed lug 34 with a flange 34a which is removably attached by cap screws 33a projectingr through openings 33o located forwardly from a cross bar 35.

The cross bar 35 extends. outwardly in one direction from said lug 34 past the steelyard housing I6 and then forwardly in alignment with the beam I9 and when in position on the beam 19 serves as a horizontal counterweight 33 [in position] the other end of the cross bar 35 extends in the opposite direction past the other side of the steelyard housing I6 and then forwardly in alignment with the beam I9 and serves as an auxiliary beam 31. The auxiliary beam 31 is in two parts, one integral with the cross bar 35 and the other part serves as an adjustable extension beam 38. The extension beam 38 is attached to the auxiliary beam 31 by a lap joint 39, held by suitable cap screws 40-40 inserted in slots lll-4I and adjustably held to the auxiliary beam 31 thereby. The outer end of the extension beam 38 is provided with a vertically aligned hole 42 having pin 43 inserted through the side wall 44 and 45. The pin 43 carries a U-shaped yoke it attached to the upper end of a rod 41 to the bottom of which is attached a basket or pan 48.

The auxiliary unit 33 can be attached to the beam of any conventional platform scale by suitable cap screws iitted into threaded holes in the regular beam I9 and brought into balance by use of the balance ball 22, as will be readily understood. An auxiliary beam 31 is provided with an adjustable extension beam 33 held by suitable cap screws 4i] attached to the auxiliary beam 31. By the arrangement of these screws and with the beam I9 in balance the whole assembly can again be brought into balance by the adjustment of the auxiliary beam 31 to the extension beam 38 as best shown in Fig. 3.

The extension beam 33 is provided with a pin 43 adapted to receive the hooked end of the rod 41 which in turn carries a basket 48. If it is desired to use the scale as a counting mechanism the extension beam 38 is set by placing one piece in the basket 48 and with ten pieces placed on the platform of the scale (not shown in the drawing) and brought into balance, and if the beam I9 is graduated for a 100 to 1 ratio the ten pieces may be placed in the scoop holder 3| which will serve as a weight which would balance times 10 or 1,000 pieces on the platform. Other similar arrangements can be made along the same lines and can be readily adapted to estimate the number of gross in a given lot. Other adaptions of the use of the scale as an estimating device by 3 varying the ratio of parts on the scale to those serving as weights on the beam will readily suggest themselves when in use.

With the use of the auxiliary beam 3T with its attendant extension beam 38 other multiples can be readily arranged.

While I have illustrated and described the details of a practical embodiment of my invention, these may be modified, altered, re-arranged, and otherwise changed without departing from the described innovations herein; I, therefore, do not wish to be limited to the precise details set forth, but seek to avail myself of such variations, modifications and changes as may fall within the spirit and scope of the appended claims.

I claim: s

1. A counting attachment for scales comprising in combination a pivotally mounted graduated scale beam with an integral body of substantially U-shape having a cross bar portion at right angles to the graduated scale beam.; a forwardly projecting elongated counterweight at one end of said cross bar portion; a forwardly projecting auxiliary beam at the opposite end of said cross bar portion; a forwardly projecting lug arranged intermediate said elongated counterweight and said auxiliary beam; a shoulder on said lug abutted to the inner end of said graduated scale beam; screw means for mechanically connecting said flange to the inner end of said graduated beam.
