CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 250,172, dated November 29, 1881.

Application filed July 5,1881. (ModeL) To all whom it may concern Be it known that I, BRADFORD SEWALL, of Farmington, in the county of Franklin and State of Maine, have invented an Improved (Jan-Filling Machine, of which the following is a specification.

The object of my invention is to provide a new and improved machine for filling cans rapidly without any waste, and which feeds and carries off the cans automatically.

The invention consists in a can-filling machine composed of a table on which a radiallywinged wheel is pivoted, between which wings the cans pass from the lower end of an open cylinder containing a stock of cans, and are carried under the nozzle of a cylinder, which isheld in a raised position byaweight attached to the outer end of a lever acting on the cylinder-frame, and in which cylinder a piston fits, which is suitably guided and actuated by a rod connected with a lever, to which a sliding bar is also connected, sliding under the table, and provided with a pawl, which rotates the can-carrying wheel.

In the accompanying drawings, Figure 1 is a plan view of my improved can-filling machine. Fig. 2 is a longitudinal sectional elevation of the same on the lineman, Fig. 1. Fig. 3 is a cross-sectional elevation of the same on the line 3 y, Fig. 1. Fig. 4 is a cross-sectional elevation of the same on the line 2 2, Fig. 1.

Similar letters of reference indicate corresponding parts.

A wheel, A, provided with a series of radial wings, B B, is pivoted to rotate in a horizontal plane on a table, 0, under which a bar, D, slides, provided with a pawl, E, which catches on the wings B B, and thus rotates the wheel A. The rear end of the sliding bar D is pivoted to an upright arm, F, of a swinging lever, G, attached to a transverse bar, H, pivoted in the frame of the machine. The lever G is provided at its front end with a handle, J, for operating it. A rod, K, attached to the lever Gr,-

extends upward, is bent at right angles, and passes into an aperture in the piston-rod L, which is guided to slide vertically on the trans- Verse bars M of the uprightframe of the machine. A piston, N, is attached to the lower end of this piston-rod L and fits in a cylinder,

or nozzle, P, which fits into apertures in the cans Q. The cylinder 0 is attached to a frame, R, sliding and guided on the upright part of the frame of the machine. The lower end of a board or bar, S, extending downward from the frame R, is pivoted to a pivoted lever, T, having a weight, U, attached to its outer end, which weight serves to hold the frame B and the cylinder 0 in a raised position. A number of cans, Q, are held one above the other in a vertical cylinder, V, of any desired height, and attached to the vertical part of the frame of the machine'in such a manner that the cans, passing from the lower end of this cylinder V, will pass in between two wings B B of the wheel A.

The table 0 is provided with a series of apertures, V, through which the waste material drops.

The guard-plate Y prevents the cans from being forced from the table and forms a curved track, along which the cans slide.

The operation is as follows: If the handle J is raised the piston N is drawn out of the cylinder O and the pawl E moves the wheel A in the direction of the arrow at. One of the wings rests against the lowest can Q of the column of cans in the cylinder V and carries it along, thus causing all the cans in the cylinder V to drop the distance of one can, and the cans will be thus successively carried off by thewheel A. The cans are thus carried under the cylinder 0, into which the material that is to be filled into the cans is passed. By depressing the handle J the plunger or piston N is pressed into the cylinder 0', and the cylinder is thus lowered, the spout or nozzle P passing into an aperture in the top of the can. By further depressing the handle J the piston forces all the material from the cylinder into the can. If the handle is raised an empty can is carried under the cylinder and the filled can is carried away and thrown outward by the wheel A. As theweight U raises the cylinder 0 as soon as the piston is raised, the wings B cannot strike against the lower end of the spoutl Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1 In a can-filling machine, the combination, with the table O, of the guard-plate Y and the wheel A, provided with radial wings B, substantially as herein shown and described, and for the purpose set forth. 7

2. In a can-filling machine, the combination, with the table 0, 0f the guard-plate Y, the wheel A, provided with radial wings B, and the canreceiving cylinder V, substantially as herein shown and described, and for the purpose set forth.

3. In a can-filling machine, the combination, with the piston' N and cylinder 0, of the rod K, the levers G and T, the frame It, and the strip or bar S, and the weight U, substantially as herein shown and described, and for the purpose set forth.

4. In a can-fillin g machine, the combination, 1 with the table 0, of the guard-plate Y, the wheel A, provided with radial wings B, the can-receiving cylinder V, the cylinder 0, the piston N, the rod K, the levers G and T, the weight U, the bar D, and the pawl E, substantiallyas 2o herein shown and described, and for the purpose set forth.
