WEIGHING APPARATUS.

SPECIFICATION forming part of Letters Patent 'No. 756,681, dated April 5, 1904:.

Application filed February 8, 190

To all whom it may concern:

Be it known that I, FREDERICK W. MoLDEN- HAUER, a citizen of the United States, and a resident of Oconomowoc, in the county of WVaukesha and State of Wisconsin, have invented certain new and useful Improvements in WVeighing Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof. I

My invention has for its object to facilitate fair distribution of skim-milk or whey at a creamery or cheese-factory; and it consists in certain peculiarities of construction and combination of parts constitutingweighing apparatus hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 represents a partly-sectional elevation of weighing apparatus in accordance with my invention; Fig. 2, a plan view of a portion of the same, partly in horizontal section; Fig. 3, an elevation of a fragment of the apparatus, partly in section; Fig. l, a partly-sectional elevation of a scale-beam latch embodied in said apparatus; Fig. 5, a plan View of a fragment of the aforesaid apparatus, partly in horizontal section; and Figs. 6 and 7 partly-sectional views respectively in of the series.

Referring by letter to the drawings, A indicates a horizontal frame attached to the inner side of a creamery or cheese-factory wall B, and a pair of opposite standards C, in connection with the frame, are joined at their upper ends to a beam D, this beam serving as a support for a horizontal stretch of a pipe E, leading from a waste-tank (not shown) in which skim-milk or Whey is accumulated. The pipe discharges vertically into a receptacle F, having outer diametrically opposite knife-edge lugs b, poised on a spanner Gr, that is in turn poised on knife-edge upper ends of vertical brackets H, secured on the frame aforesaid. The outlet of the pipe E is controlled by a self-seating valve I, having the stem thereof forked on a lever J, suspended at one end by a link 0, hung on ahook d, in connection with the beam D, and the other end of this lever is connected by a link K with a central shank Serial No. 192,631. (No model.)

G of the spanner Gr, this shank having its play above a stop-shoulder c of a standard L, fastened to the frame A, above specified.

Connected to the bottom of the receptacle F, in communication with a central outlet of same, is a partly-flexible pipe M, an inflexible portion of this pipe being suspended from the frame A in hangers f and coupled to a delivery-spout N, it being preferable to employ a cock-controlled union P between said pipe and spout. A self-seating valve Q is employed to control the outlet of a receptacle F, and the stem of this valve is connected by a link g to a chain 71, having adjustable connection by a bolt a and nut with an end of a lever B, that is connected at its other end to the link K, an intermediate shackle portion of said lever being in pivotal connection with the standard L aforesaid. Another link S is shown in connection with the spanner-shank G, and the upper end of this lever is made to form a half-round longitudinal recess for the reception of an adjustable rod in, that is held in place by a clamp consisting of a pair of plates m, bolts 07. extending through the plates and nuts p run on the bolts. The rod in is coupled to one arm of a bell-crank lever T, and the other arm of this lever is connected by a wire 9 or other suitable means with an arm of a similar lever U more or less distant therefrom. The other arm of the bell-crank lever U is connected by a rod 1" with the shank of a yoke V, and engaging this yoke is a scalebeam W and an arm of another bell-crank lever X, rigidly connected by any suitable means to said beam. The bell-crank lever X is fulcrumed to a bracket 8, fast on a suitable support Y, and its other arm has a weight t, adjustable thereon. A latch 14 is pivotally connected to the bracket 8 to engage with notches in an edge of the weighted arm of the bell-crank lever X, and a stop-lug c on said lever-arm is in the path of an end hook it of the latch. The coupling of the yoke V and rod 9" is preferably similar to that of the link S and rod k, as is herein shown, and the connection of the scale-beam with the bell-crank lever X constitutes what is virtually a scalebeamhaving a counterweighted angle-arm and which is hereinafter so termed. A weighthanger w is suspended from the yoke V, and a sliding weight Z is adjustable on the scalebeam W, downward play of this beam being limited by a stop a: on the support Y aforesaid.

As shown in Fig. 1, the yoke V and scalebeam W have been Weighted for a known quantity of skim-milk or whey. Due to this operation the spanner Gr has been lifted on the brackets H to elevate the receptacle F and lift the valve I from its seat. When this is done, the scale-beam is temporarily locked in horizontal position by an engagement of the latch u with the upper notch in an edge of the bell-crank lever X, and there is flow of skimmilk or whey into the receptacle F until the latter and its contents overbalance the predetermined weight, the result being a descent of said receptacle, lift of said scale-beam, automatic release of said bell-crank lever from said latch, reseating of valve I, and unseating of valve Q, so as to permit flow of said skimmilk or whey through the partly-flexible pipe M and delivery-spout N, if the cock-controlled union P of the two be open. Incidental to this operation the upward swing of the scale-beam is arrested by engagement of the latch-hook a by the lug "u of the bell-crank lever X, and at the same time the latch M is caught in the lower notch of an edge of the weighted arm of said lever to prevent automatic descent of said scale-beam.

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

1. A spanner poised on suitable supports, a receptacle poised on the spanner, a tank discharge-pipe having outlet into the receptacle, a self-seating valve controlling the pipe outlet, a similar valve controlling an outlet of said receptacle, a weighing-scale, means in conjunction with the spanner, valves and scale for automatic unscating of the respective valves according as there is preponderance of weight on said scale or in the receptacle; and means for automatically locking the aforesaid scale when the preponderance of Weight is in said receptacle.

2. A spanner poised on suitable supports, a receptacle poised on the spanner, a tank discharge-pipe having outlet into the receptacle, a self-seating valve controlling the pipe outlet, an unseating-lever :liorthe valve, a similar valve controlling an outlet of said receptacle, an unseating-lever in connection with the latter valve, a link connecting the valve-levers and a shank of said spanner, one valve being seated when the other is unseated; a weighingscale having connection with the spannershank, and means for automatically locking the scale when there is preponderance of Weight in the aforesaid receptacle.

3. A spanner poised on suitable supports, a receptacle poised on the spanner, a tank discharge-pipe having outlet into the receptacle, a self-seating valve controlling the pipe outlet, an unseating-lever for the valve, a similar valve controlling an outlet of said reci-u itacle, an uuseating-lever in connection with the latter valve, a link connecting the valve-levers and a shank of said spanner, one valve being seated when the other is unseated; a tilting scale-beam having a counterweighted anglearm, a yoke with which the scale-beam is engaged, link-and-lever mechanism connecting the yoke and spanner-shank, a pivotal latch engageable with a notched edge of the scale beam arm, a lug on said arm cngageable with an end hook of the latch, and a weight adjustable on said scale-beam.
