To ad whom, it may concern.-

Beit known that I, ALEXANDER W. COP- LAND, a citizen of the United States,` residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements inDepositing-Machines, of which -the following is aspeciication, reference being had thereinto the accompanying struction, arrangement, and combination of the various parts, as more fully hereinafter descrlbed, and partlcularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my machine, showing the lower part of the hopper and the plunger-cylinder and discharge-nozzle in section. Figs. '2, 8, 4, and 5 are sections through the cylinder, hopper, and

nozzle, showing the different positions of the plunger-valve and nozzle. f

A is the frame of the machine, which supports the operating parts, including ythe main driveshaft B,.which is driven from any suitable source of power. On the frame are the side brackets B', which support the hopper C, having a discharge-throat C' at the bottom. On

the front face ofthe base of the hopper I secure y the cylinder or cylinders D. In thiscase I have shown the base of the hopper provided with a flat face a, to which the cylinder (which is in the shape of a U-shaped casting) is bolted by bolts b at the ends, leavinga space between in which is located the piston E. The cylinder has a foot E', extending down below the base of the discharge-port from the cylinder, and the hopper has a foot F opposite the foot E. In these two ,feet are formed suitable guides, in which slides the valveG, having the U-shaped port G' therethrough.. Below the valve is secured the nozzle-plate H, preferably by means of the clamping-plate F'. In the nozzle-plateV are a series of nozzles c, havingl the rearwardly-inclined discharge 0l. The

valve is reciprocated by means of the levers I,

one at Aeach side of the machine, which are connected to the valve bylinks` I', these levers being fulcrumed inthe base of the machine on the shaft 0l.- On the shaft Z is secured the rock-arm 0l",which has the roller al, adapted to engage and be operated by a cam having a camway e on the drive-shaft B". Thisconstruction causes the shaft d' to be rocked,'and

with it the levers I, which causes the valve to` reciprocate back and forth. In one position, Fig. 5, the port Gr' of the valve will cut of'the port L through the nozzle and will connect the discharge-throat of the, hopper with the cylinder and in the other position, Fig. 2, will cut oif' the discharge-throat of the hopper and connect the cylinder withv the discharge nozzle or nozzles. The piston is actuated by the two connecting-rodsJ, one at each end, -which connect to the slotted lever J', secured tothe shaft J. -V This shaft has a rock-arm K,wh1ch is connected by the connecting-rod K w1th an eccentricL on the shaft B causing the piston to be vertically reciprocated. Its upward movement draws the material from the hopper (the valve being in the proper position) and the downward movement discharges the material through the nozzles, the valve being shifted in the meantime. y

M is atable pivoted atM' at one end, and at its other end is supported on the rods N, which at their lower ends are connected to the rockarms N', secured vto the shaft N in the base of the machine. the rock-arm O, which has a roller O bearing against the cam P on the shaft B constructed so that the table will be tilted on its pivot, be-

ing raised and lowered at the proper times.

Running over the table is-an endless carrier Q, which maybe in the shape of a belt of any desired construction. This carrier runs over the wheels or rolls S and S' at opposite ends and is actuated at the proper interval by means of thel pawl v1 on the lever 7c', journaled on the shaft Z and actuated by a bell-crank lever m, to which thelever c is connected by the link n. The bell-crank lever fm, is operated by engage'- ment with the cam o on the shaft B in one To this shaft is connected n yIOC direction and by the spring o on the reverse direction.

The parts being thus constructed their operation is as follows: rIhe hopper being filled with the desired material the pans are put on the carrier running ov er the table and beneath the nozzles, the piston is driven upward through the connections described, the valve at that time connecting the cylinder with the hopper, and the material will be drawn into the cylinder below the piston. The valve will then be shifted to the position shown in Figs. l and 2, registering the port G in the Valve with the port z in the nozzle', which will cause the material as the piston descends to discharge from the nozzle onto the pan beneath. When the deposit has been made, the valve will be shifted to cut 0H the connection between the cylinder and the nozzle.

By reference to Figs. 2, 3, 4, and 5 the operation of cutting off the dough in the nozzle from that deposited will be understood. As soon as the valve closes the table begins to lower, and at the same time the feed-apron moves forward, which will lower the face of the deposit across the rear face of the nozzle and also carry back onto the deposit any string, thread, or connection there may be between the dough in the nozzle and that del posited. This movement being comparatively rapid will not only deposit the thread or connecting filament on the deposit, but also quickly sever that thread which would otherwise connect the nozzle with the deposit. These operations, as previously described, are illustrated in diagram in Figs. 2, 3, 4, and 5. The apron feeds forward beyond the deposit already made, and the table is again lifted in proximity to the nozzle for a second deposit adjacent to the first.

It is well understood in the manufacture of these machines that I may employ a single nozzle for a single deposit or that I may employ a series of nozzles arranged side by side, and I may employ a single piston or a series of pistons, one for each nozzle, and this Ithink will be readily understood from the known construction in such devices without further illustration.' I prefer, however, to use a single piston and a single port in the valve and a single slot in the discharge-throat of the hopper, for thereason that it reduces friction and also is more readily cleaned.

By removing the screws which hold the clamping-plate F' the valve may be removed,

J, I mount sprockets on these shafts and conneet them by a chain in the same manner.

What I claim as my invention isw 1. In a depositing-machine, the combination of a stationary material receptacle and cylinder having their discharge-ports side by side, a perforated nozzle-plate below the same and a valve between these discharge-ports and said plate having an opening therein, means for reciprocating said valve to connect the two.

discharge-ports and close the port in the nozzle-plate, or to shut olf the discharge from the receptacle and connect the cylinder-port with the perforations in the plate.

2. In a depositing-machine, the combination of a hopper having a vertical discharge-port, a cylinder arranged beside the same, a piston therein, a horizontally-reciprocating valveplate below the discharge-ports from the cylinder and receptacle having an opening or openings therein adapted to connect or disconnect the two ports, a perforated plate below the valve-plate, the ports therein adapted to be registered with the openings in the valveplate when the hopper connection is shut off and nozzles on the perforated plate.

3. In adepositing-maehine, the combination of a hopper, having a discharge-port at the bottom, and having a plain face (t on one side thereof, of a cylinder D formed in the shape of a U-shaped casting bolted against the face a, a piston in the cylinder thus formed, a nozzle-plate detachably secured to the base of the hopper and a reciprocating val ve between the nozzle-plate and the hopper and the cylinder discharge, for the purpose described.

4. In a depositing-machine, the combination of a material-hopper, a nozzle-plate below the same, means for discharging material from the hopper to said nozzle-plate intermittently, a reciprocating table below the nozzle-plate, means for feeding the deposited material on said table, the parts being combined so that as the table is lowered the deposits are fed forward whereby the deposit will move downwardly and forwardly in relation to the nozzle for the purpose described.

5. In adepositing-machine, the combination of a material-receptacle, the nozzle-plate bclow the same, nozzles thereon having a rearward discharge, a reciprocating table below the nozzle-plate, means for feeding the material along the table, the table-reciprocating means and the feeding means being so combined that the forward feed will take place as the table lowers for the purpose described.
