NrTnn STATES PATENT FFICE@ CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,795, dated October 30, 1888.

A pplcation iiled March 17,1885.

To @ZZ whom it may @encerrar Be it known that I, JOHNT B. HO'DAPI?, a citizen of the United States, residing at Mankato, in the county of Blue Earth and State of Minnesota, have invented certain new and useful Improvements in Can-Filling Machines; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to can-filling ma chines; and it consists in the novel construction and combination of the parts, as herein after fully described and claimed.

In the drawings, Figure l is a side view of the complete machine. Fig. 2 is a plan View of the gage-plate and the end of the dippingtrough. Fig. 3 is a front view showing the hopper and cantable in section. Fig. 4 is a plan View of a portion of the feed pan and the feed mechanism under it. Fig. 5 is a vertical cross-section on line x x in Fig. Fig. 6 is a cross-section through the receptacles for the cans, and Fig. 7 is a perspective View of the plunger.

A is the frame of the machine, and A is the dipping-trough. Fast and loose driving-belt pulleys a e are secured upon the shaft I3,which is journaled in the frame A, and abeltshifter, b, is provided for stopping and starting the machine.

B is the ily-wheel, and b is a pinion, both of which are secured to shaft B.

O is a shaft, also journaled in the frame and provided with the toothed wheel C', gearing into pinion b, and provided also with the pinion c.

D is a shalt journaled in the upper part of the frame and provided with the toothed wheel c', gearing into pinion c. The crank D and beveled pinion d are also secured upon shaft D.

E is a vertical shaft provided at the top with the beveled wheel. d', gearing into pinion d.

Fi is the feed-pan, secured to the frame, and c are revolving arms secured upon shaft E within the pan. A small beveled wheel, e', is secured upon the shaft E for driving the feedcylinder F, which is secured upon the shaft F', which has also the beveled wheel f secured upon it and gearing into the said wheel e.

(No model.)

Gf is the feed-hopper, and G is the Iced'cylinder casing at the lower part of the hopper.

The feedcylinder F has iixed ilanged arms f and straight arms g. Loose iianged arms g are provided and adjustably secured to the said straight arms by screws. The lianges of arms g slide under the ilangcs ofthe fixed arms, and the amount of material fed from the hopper maybe varied by means of the screws, which cause the loose hanged arms to approach or recede from the xed arms, and thereby vary the size of the intervening pockets for material in the feed-cylinder.

His the throatpiece, into which the material from the feedeylinder is swept by the revolving arms e, and H are the iillers, secured to the under side of the throatpieee and separated from each other by the partition h, which projects upwardly from the bottom. of the fillers and is not connected to their sides.

I is a plunger provided with the square pl unger-rod I, sliding in the guides fi, and operated through the connecting-rod t" by the crank D. The plunger has a central hole, into which the partition 7L may enter when the plunger descends, and li are plates which strengthen the plunger and slide in the narrow spaces between the ends of the partition and the sides of the fillers.

VJ is the feed-slide, and J is the cover-plate at the bottom of the fillers,which supports the slide in close contact with the base of the illers. The base of the fillers, the slide, and its cover-plate are each provided with similar holes, j and j', which register when material is being forced out of the fillers into the cans by the plunger. Of these holes, j is asegrnent of a circle and is for the passage of material, and j is a small round air-hole.

K is a cross-hole which is formed laterally through the side of each filler into the air-hole j', and K is a valve which closes the top end of hole j inside each filler. rlhe valves K prevent the material passing downward through holes j when the plunger descends and permit the escape of air from the cans through the holes K. When the plunger ascends, the valves K admit air from the crossholes K to the under side of the plunger, so that the contents of the can are not sucked up again.

IOO

L is a cam provided with rollers Z, which bear against the plate Z, secured to the end of the feed-slide. These rollers roll upon the plate Z and hold the feed-slide so that it closes the holes j j of the feeders during the greater part of the revolution of the cani L, which is secured upon the vertical shaft E.

L is a spring, which pulls open the feed-slide directly the cam leaves the plate Z. The synchronous motion of the feedcylinder and the revolving arms alternates with the descent of the plunger, and the feed-slide Ais opened in time to allow the plunger to force the material out of the fillers into the cans. The continued revolution of the cam L closes the feed-slide when the downstroke of the plunger is complcted.

M is the can-table,secured to the framing A, and M is a vertically-rising plate normally supported in a recess in the top of the table and flush with its surface. This plate is provided with the stem m, and m is a spring surrounding the stem and bearing against the lever N, which is pivoted to the frame A at one end. A roller, a, isjournaled at the other end of the lever, and N is a face-cam secured on the vertical shaft E. The roller n is raised by the cam just before the feedslide is opened, so that the cans which are standing on the said plate are pressed tightly against the under side of the coverplate J. A guide, n, is secured tothe top of table M, for keeping cach pair of cans at the proper distance apart until they pass onto the plate M.

O is an endless carrier, consisting of two side chains united by cross-bars O, for moving the cans along. This carrier is supported by the carrier-wheels o, journaled upon shafts at the front end of the can-table and at the necessary points in the di pping-trough to make the cans pass through it. The carrier is moved by the carrier-wheels o', secured upon the shaft P, journaled at the rear end of the can-table. This shaft Pis provided with the ratchetwheel P for turning it, and p is a slotted arm pivoted on the shaft I?, and provided with the spring-pawlp for operating the ratchet.

Q is an adjustable connecting-rod, which operates the arm p from the crank D.

Q] are the receptacles for the cans,supported above the rear end of the cantable by the braclgets q, and qare adjustable guides bolted to the lowerv ends of the said receptacles for straightening the tops of the cans as they pass from under the receptacles.

The motion of the carrier is adj usted so that two empty cans are delivered upon the vertically-rising plate M, and are held between it and the plate J just before each descent of the plunger in the fillers and the opening of the feed-slide.

The carrier O passes through the dippingtrough A and returns underneath it vto the rear end of the machine. It and R are guideplates secured, respectively, at the receiving and delivery ends of the trough for supporting the cans as they descend and ascend. A. coil ofsteam-pipes, 1', is provided in the-bottom of the trough for the cans to pass over, and r is a plate supported within the trough for keeping the tops ofthe cans straight. The trough is partly filled with water or other liquid in which it :may be desired to dip the cans, and this liquid is kept boiling by the steam-pipes r, so that the contents of the cans are heated and steam is formed in them,which drives out all the air. When the cans come up out of the trough, they are ready to be capped, by which operation they are made air-tight, and their contents thereby preserved from decay.

S is the gage-plate, supported by brackets S at the delivery end ot' the trough. This plate is provided with the strips s, for spacing the cans, as they pass onto it from the guideplate R, which is also provided with the tapering guide-stripr at its upper end.

T are curved adjustable guides for evening the tops of the cans as they pass over the gage-plate. These guides are provided with slotted arms T and are secured tothe brackets S by the bolts t.

The shafts which carry the carrier-wheels o are journaled in loop-brackets U, which are secured to the sides of the trough by the setscrews U, so that the position of the said wheels can easily be varied. In asimilar manner the 'brackets V, which carry the guideplate r', are held to the trough by set-screws V', so that the height of the plate may be rcgulated.
