AUTOMATIC MEASURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 634,634, dated October 10, 1899 Application filed November'l'i', 1898. Serial No. 696,745 (No model.)

' T0 aZZ whom, it may concern:

a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Automatic Measuring Device, of which thefollowin g is a specification.

The object of this invention is to provide a cabinet of simple, strong, durable, and inexpensive construction in which a number of different kinds of granular substances may be stored and uniform given quantities of such substances be quickly and easily taken therefrom.

My object is further and more specifically to provide mechanism of improved and simplified construction for measuring the substances and discharging same.

My invention consists, essentially, in the details of construction of the valves and their operating means and in the combination there; of in the cabinet, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in

which- Figure 1 shows a side elevation of one of the complete measuring devices detached from the cabinet and with parts broken away to show certain details of construction. Fig. 2 shows a plan view of one of the valves, and Fig. 3 shows a perspective view of the cabinet with one corner of the casing broken away to show the arrangement of the measuring devices therein.

Referring to the accompanying drawings, 1 have used the reference-numeral 10 to indicate the frame of the cabinet, which is divided into compartments by the partitions 11. In the-top of each compartment is a hopper 12, in which the substance is stored. At its frontisahinged door 13, which may be opened to provide access to the measuring devices, and the front is open at its bottom to provide access 'to the measured substances.

At the bottom of each of the hoppers is a tube 14:, which is preferably square in crosssection, open at its top and bottom and having the openings 15 in its front and back sides near its top and the like openings 16in its lower end portion. A tube-section 17, also square transversely, is telescoped over the upper end of the tube let and has narrow hori zontal slots at its front and back, the vertical slots 18 at its sides, and the tracks or guides 20 at its, sides below the slots 18. A screw-bolt 21 extends through the solid sides of the tube 14 and through the slots 18, thus providing for the vertical adjustmentof the tube 17 on the tube 14. A tube 23 of identical construction is mounted on the lower end of the tube 17. The uppervalve is composed of a rectangularmetal frame 23, hav ing the inner edges of its side pieces designed to enter the tracks or guides 20 and be capable of sliding longitudinally therein. In the outer edges of-said side pieces, near the forward end thereof, are the notches 24. In the central portion of the frame is the valve proper, 25, attached to the said frame at its front and back only, with a space between its edges and the side of the frame and having the rear end thereof cut away, save, for a den- .tral supportingpiece, for about one-third of its length.

Mounted in the lower tube-section 22 is a valve of identical construction provided with a handle 26 to project forwardly therefrom.

At the central portion of the tube 14 is a frame 27, having at its forward corners the journals 28, upon which the lovers 29 are fulcrumed. Said levers have tapered ends which enter the notches 24 in both valves, which valves are so arranged that when one is at its forward limit the other is at its rearward extreme.

d In practical use and assuming thatthe device were in the position shown in Fig. 1 it is obvious that'the contents of the hopper would fill the entire tube 14 as far as the lower valve. When it is desired to measure out a quantity of the substance, the handle 26 is pulled. lowervalve forwardly and, by reason of the levers 29, forcing the upper valve rearwardly.

The said'upper valve is of such size as to close the opening through the tube 14: before the opening in the lowervalve comes into the tube 14, thus shutting 0d the upper end of the measurer. Then as the handle 26 is drawn further the opening in the lower valve' permits the measured substance in the tube to passout through the bottom of the tube.

This has the effect of drawing the Then as the handle is again pushed back the lower valve closes the tube before the upper valve is opened. WVhen said upper valve is finally opened, the tube 14 is filled again. By reason of the openings in the front and back of the tube let the valves may be adjusted upon the tube and freely operate at any point Within the limit of the said openings. This adjustment is had by means of the screwbolts at the sides of the movable tube-sections.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States therefor, 1s-

1. In an automatic measuring device, an open-ended four-sided tube, tracks on the outside faces of two of the parallel sides of the tube, slots across the other two sides of the tube in the plane of the tracks, a frame fitted to slide on said tracks and a valve fixed to the frame to slide through said slots in the manner set forth for the purposes stated.

2. In an automatic measuring device, a quadrangular frame, having notches in its parallel sides for slidingly connecting levers therewith, a float-valve fitted in the frame and fastened to the ends of the frame in such a manner as to leave narrow spaces between its side edges and the parallel side bars of the frame, in combination with an open-ended four-sided tube having tracks on two parallel sides to support said frame and valve and transverse slots in its other two parallel sides for the passage of the valve fixed to the frame and levers to enter the notches in the frame, all arranged and combined to operate in the manner set forth for the purposes stated.

3. An automatic measuring device, comprising a tube having horizontal openings at its front and back at each end guides or tracks fixed to the outer surfaces of the sides of the tube adjacent to said openings, a valve at each end, each valve comprising a frame mounted for movement in said track, and a valve proper fixed in each frame to pass through said openings and having a part at its rear end open, and levers fulcrumed to the central portion of the tube and slidingly connected Wit-h each of said frames carrying fixed valves to operate in the manner set forth for the purposes stated.

4. An automatic measuring device, comprising in combination, an open-ended tube rectangularin cross-section, and having openings inits front and back near its top and bottom tube-sections adjustably teleseoped to said ends and having narrow slots in their front and back faces, tracks or guides at their sides, rectangular frames mounted in said guides and having notches therein, a handle attached to one of the frames, a valve in each frame open at its rear end and two levers fulcrumed to the central portions of the tube with their ends in said notches substantially as and for the purposes stated.
