FEED IVIECHANISM FOR WEIGHING-lViACHINES.

SPECIFICATION forming part of Letters Patent No. 470,146, dated March 1, 1892.

Application filed April 29, 1891- i770 a/ZZ whom t may con/cern:

Be it known that 1, HENRY E. SMYSER, of the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improved Feed Mechanism for NVeighing-lvfachines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to weighing-machines of the general character shown and described in my patents Nos. 449,275 and 449,276, of March 31, 1891, but more particularly to the improved Weighing mechanism described and claimed in my pending application led April 15, 1891, Serial No. 389,030, in which said application a series of stationary scale-pans are charged seriafim by a measure which is alternately filled and emptied into the differ! ent pans of the series. The object of my present invention is to simplify the said apparatus and increase its feed by providing means for simultaneously charging all the scale-pans of l the series.

The nature of my invention will be best understood as described in connection with the drawings in Which it is illustrated, and the novel features which I desire to protect are hereinafter clearly set forth in the claims, reference being now had to the drawings, in Which- Figure 1 is an elevation of a part of an automatic weighing-machine, showing my improvement; Fig. 2, a plan view of the same, and Fig. 3 a plan view on the section-line xx of Fig. 1.

A is a hopper through which the material to be weighed is fed to the machine. At the bottom of the hopper and forming a continuation of it is the chute B, having brushes or Scrapers B on its front and rear edges and, as shown, an opening B2 at its end.

C is a box or platform situated beneath the chute B and having a bottom O', through which a series of openings C2 are formed in a line lying in front of the chute B. The openings 02 correspond in number to the scalepans of the machine.

D is a reciprocating box resting on the platform C and having a motion from a point be- Serial No. 391,020. (No model.)

neath the chute B to a point over the openings C2. The box D is divided into a series of measuring-chambers D', the divisional partitions being so placed that one of such chambers will register with each one of the openings C2.

D2 indicate extensions from the bottom of box D to increase the bearing of the same on the platform C', upon which it slides.

E isa plate extending out from the back of the box D and having, as shown, a series of tongues E', which extend down into each of the measuring-boxes D', said tongues serving the purpose of an adjustable side to the box or compartments by which its contents can be regulated. The movable sides are adjusted by means of the screw E3, the end of which is connected with the back of the box D and upon which is a nut E2, said nut being attached to the plate E. The desired reciprocating' motion is given to the box D by means of the rod F, 'the lever F F3, pivoted at F2, and the cam F4, with which the end of lever-arm F3 :is engaged.

I I, Fig. 1, indicate scale-pans, of which there may be any desired number, preferably arranged in a circle and at equal distances apart. Above each scale-pan and opening into it is a chute H, the tops of said chutes being connected byconduits G, each with one of the openings C2 in the platform O.

The operation of the machine is of the simplest kind. The measuring-box is moved so as to open to the hopper A-g-that is, in the design shown the box D is drawn back until it is directly beneath the chute B. When each compartment of the box is filled, the box is moved forward to the position shown in Fig. l, the brush B sweeping off the ma-v terial level with its top, and the plate E closing the mouth of chute B when the box is moved away from under it. As soon as the series of measuring-compartments register with the openings C2 their contents fall out into the said openings and pass through conduits G and chutes H to the series of scalepans I.

The additional or supplemental feed to the scale-pans can be effected in any of the Wellknown ways-such, for instance, as is shown in my patents of March 31, before mentioned.

In the drawings I have indicated a feed-box K, supplied by chute J from the hopper A, said chute connecting with the hopper through the opening B2; butI have not thoughtit nec- 5 essary or advisable to illustrate the mechanism by which the feed-box K is made to supply the different scale-pans with a regulated supply of material, because such mechanism forms no part of my present invention and is fully described and shown in my former patents and application.

The essential and important feature of my present invention lies simply in the provision of a series of measuring-boxes with means for filling the same and means for intermittently connecting each measuring box or compartment, With one of the series of scale-pans, so that said pans can be supplied with measured quantity of material simultaneously, instead of receiving such measured quantities scriatm.

Having now described my invention, what I claim as new, and desire to secure by Iletcombination, with a series of scale-pans, of a series of chutes leading to the respective pans, a corresponding series of measures, a supplyhopper, and means for actuating the 1neasures, as described, and so that they shall alternately communicate with the supply-hopper and the chutes.

2. In an automatic Weighing-machine, the combination, with a series of scale-pans, of a series of chut-es leading to the respective pans, a reciprocating box divided into measuringcompartments corresponding to the chute series, a supply-hopper arranged above the box, a platform to support and guide the box having at one end a series of holes corresponding to the divisions of the box and connecting to the chute series, and mechanism arranged to actuate the box, moving it to and from a position beneath the hopper to and from a position over theholes in the platform.

H. E. SMYSER.
