JOHN COLBERT, OF MANTUA, NEV JERSEY.

CAN-FILLING MACHINE.

SPECIFICATION forming" part of Letters Patent No. 286,782,1lated October 16, 1883.

Application filed August $10, 1883. (No model.) f

To aZZ whoml it may concern,.-

Be it known that I, J OHN COLBERT, a citizen of the United States, andaresident of Mantua, Gloucester county, New Jersey, have invented certain Improvements in Can-Filling Machines, of which the following is a specification.

The object of my invention is to so construct the can-carrier and valve of a can-filling machine that the can may be readily applied to the filling-spout, and a tight joint insured between the top of the can and the valve. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which i Figure l, Sheet l, is a front view of theV machineY with my improvements; Fig. 2 a longitudinal section of the same; Figs. 3 and 4, Sheet 2, enlarged sectional views of parts ofthe machine, and Figs. 5 and 6 perspective views of the valve'and can-carrier.

A represents the frame of the machine, having cross-bars c, a', and c. The bar a supports the hopper B and filling-spout B, the Ahopper having a strainer-plate, `b, for separating the juice from the solid portions of the tomatoes or other vegetables, or of the fruitwhich. is to be packed, the juice passing o through a pipe, b', to any suitable receptacle.

To the filling-spout is fitted the plunger D, which is secured to a cross-head, d, guided in the frame A, the outer ends of"said crosshead being connected by chains gto a treadle, G, and being also acted upon by springs c, which tend to raise the cross-head and plunger when pressure is removed from the treadle.

To guides f on a valve-box, I, secured to j the spout B", are adapted the edges of a valve,

E, which is free to slide in said guides, springs on tending to retract the valve, so as to close the opening in the filling-spout, andthe valve being moved inward, so as to bring its opening i' in line with that of the filling-spout when the can is to be lled.

The can rests upon a table, F, which is hung by means of links k to the vcross-bar a2 of the frame, and the movement of the table is limited by stops n a on the bar. On the table is a gage, 71., and on the valve E is a projecting 5o finger, p, the outer end of the valve having a ange, j, which limits the inward movement of said valve by contact with the end of the valve-box. Y

The operation is as follows: A can, fr, being placed on the table F and against the gage h, is pressed inward, as shown by the arrow. in Fig. 3. Owing to the `links lr, this movement causes the table to rise, so as to apply the mouth of the can tothe anged 6o opening t' of the valve E, the said valve being moved inward by contact of the can with the finger p, so as to cause the,f opening i to coincide with the mouth of the filling-spout, and thus permit the tomatoes to be forced into the can on the descent of the plunger D, the links k being in the vertical` position shown in Fig. 4, so as to effectually resist the downward pressure. On retracting the iilled can the valve will be drawn out by the springs m, 7o so as to close the mouth of the spout, the can falling with the table F, so as to clear the valve and permit its removal and the application of' an empty can. Between the ar a and the supporting-lugs on the spout B are interposed blocks s, of rubber, or other suitable springs, so that the spout will be at liberty to yield slightly in a vertical direction when subjected to pressure caused by a sud-` den descent of the plunger D, there being suf- 8o ficient play between the valve and can to permit this slight movement.

rlhe usual vent-tube, f, is provided for the escape of the air from the can as it is being filled and for the discharge of the surplus juice and pulp. Y

Although I prefer to actuate the valve E by the can asthe' latter is moved into position, the valve may be otherwise arranged, and may be operated independently of the 9o can, the latter being applied direct-1y to the mouth of the lling-spout.

I claim as my inventionl. The combination of the filling-spout, the can-holding plate, the supporting-bar, and a link-connectionbetween said plate. and the bar, as set forth.
