Application January 23, 1948, Serial No. 4,025

2 claims. i 01. 265-30) The invention relates to new and useful im- V provenients in scales but more particularly to scale beams having an auxiliary 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, economical to manufacture, and highly eilicient 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 specification and in which:

Figure l is a side elevation of 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 2 2 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 I5 of a platform scale mounted at the top of conventional steelyard housing I6. A fulcrum bearing I'I is attached to the upper part of the steelyard housing I6 and below the head I5 in position to operatively receive a knife-edge pivot I8 attached to a conventional scale beam I9 intermediate its ends. A sliding poise is arranged on the beam I9 and carries a clamping screw 2| which serves the purpose of holding the said poise 20 in a selected position on saichbeam I9.

A balance ball 22 is adjustably carried by a threaded shaft 23 at the inner end of the beam I9 which is of a conventional type and serves the purpose of setting the beam I9 in balanced relation, as will be readily understood. Arranged below the balance ball 22 and attached to the beam I9 is loadpivot 24 from which is suspended a bearing loop 25 which in turn supports la steelyard rod 26 by a hooked end 2l thereof.

The outer end of the beam I9 is projected through a slotted guard frame 28 provided with a beam latch 32 for holding the said beam I9 in inoperative position, and a counter poise loop 29, hung from a tip pivot 30, from which is suspended a scoop holder 3|.

The beam I9 is further provided at its inner end with an auxiliary unit 33 having a centrally placed lug 34 with a flange 34a which is remov'- ably attached by cap screws 33a projecting forwardly from a cross bar 35.

The cross bar 35 extends outwardly in one direction from said lug 34 past the steelyard hous-y ing It and then forwardly in alignment with the beam I9 and serves as a horizontal counterweight 35 in position; the other end of the crossbar 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 beam13l. 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 3l by a lap joint 39, held by suitable cap screws 40-40 inserted in slots 4I4I and adjustably held to the auxiliary beam 3l 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 46 attached to the upper end of a rod 4l 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 fitted 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 3l is provided with an adjustable extension beam 38 held by suitable cap screws 40 attached to the auxiliary beam 3l. 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 38 is provided with a pin 43 adapted to receive the hooked end of the rod 4l 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 l ratio the ten pieces may be placed in the scoop holder 3l which will serve \as a weight which would balance l0() 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 rof the scale as an estimating device by varying the ratioof parts on the scale to those 3 serving as weights oii the beam will readily suggest themselves when in use.

With the use of the auxiliary beam 31 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 modied, altered, re-arranged, and otherwise changed without departing from the described innovations herein; I, therefore, do not wish to belimited to the precise details set forth, but seek to avail myself of such variations, modications and changes as may fall within the spirit and scope of the appended claims.

I claim:

l. 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 projectingl elongated counter weight 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 counter weight 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.

2. In combination with a horizontal scale beam of a counting unit comprising an outwardly extending cross bar at right angles to said horizontal scale beam; a forwardly extending auxiliary beam at the outer end of said cross bar in spaced and parallel relation with said horizontal scale beam; a forwardly extending lug at the inner portion of said cross bar; a forwardly extending half joint flange in vertical alignment with one vertical side of said horizontal scale beam; screw means for mechanically securing said iiange and said lug in abutted position with the inner end of said scale beam: a forwardly and horizontally extensible end beam connected by half joint laps secured by mechanical screw means to said auxiliary beam; a vertically placed eye in the outer end of said extensible end beam in which a hook engaging pin is centrally and horizontally secured; there being elongated holes adjacent the inner end of said extensible end beam'.
