CAN-FILLING MACHINE.

'SPECIF'KCATION forming part of Letters Patent No. S14-,352, dated March 24, 1885.

To all whom it may concern.-

Be it known that l, WILLIAM H. H. STE- VENSON, a resident of Baltimore city, Maryland, have invented certain 'new and useful Improvements in Can-Filling Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof, in which- Figure l is an end elevation of myimproved machine, showing mechanism for exhausting the air in connection therewith. Fig.2 is a central longitudinal vertical section of the machine. Fig. 3 is a top plan view, the ropes and pulleys being omitted; and Fig. 4 isasectional detail.

Like letters of reference mark the same parts in all the figures.

My invention relates to machines forfilling cans with liquids; and it consists in the construction, arrangement, and combination of parts, which will be first fully described, and afterward pointed out specifically in the claims.

Referring to the drawings byletter, A is the tank; A', the cylinder; A2, the piston; A3, the pipe through which air enters the tank, and A4 the pipe through which the air is exhausted.

The pipe A3 communicates with the llingmachine by means of a flexible section, A5, and is provided with a small branch pipe, a, leading vertically downward, and communicating with a reservoir, c', having Aa valve, c2, in its bottom.

B is the pipe (attached to the machine) with which the exible section A5 is connected, and it is furnished with a valve, B', havingastein, B2, and which is normally closed.

To any suitable support overhead are at-V tached two rods, Gnhaving each a pulley, c, in its forked end, over which passes a rope, C', whose outer end carries a weight, C2, and whose inner end is attached in an eye, c', on the end of a rod, C, which passes through a bracket, Ct, attached tothe upper portion of the end walls of a tank, D, and is at its lower end passed through a plate, E, being securedthereto by nuts e. Upon thisplate E, on suitable supports, rests a pan, F, in which the cans, 5o f, to be filled are placed. f

The machine as here illustrated has aca- Application tiled April 10, 1884. (No model.)

pacity of fifteen cans at once, and this pan is consequently of sufficient size to receive them, being placed in three .rows of five each. The tank D has secured to the end walls another pair of brackets, D', through which pass rods D2, which are secured at their upper ends to a plate, G, by nuts d, and at their lower ends to a bar, D, by means of nuts d. This bar D: passes under the tank D, and has secured to it a treadle, D4, which treadle is pivoted at di, and in bearing attached to the bottom of the tank D.

Secured to one side of the tank D is an upright projection, D5, and to the other side an uprightLDG, having its upper end, D7, bent at right angles thereto. The plate G in its central portion is formed into a tank, G', which communicates through the pipe B with exhaust-tank A. The pipe B may be divided intok a number of branches, as may be desired, each branch communicating with the tank G'. The bottom of the tank G coutains as many perforations g as there are cans to be filled at one operation. Each of these perforatious is surrounded (see Fig. 4)

by a projecting nipple, h, cast or otherwise formed onto the bottom ot' the tank, the nipples having an interior diameter slightly greater than the diameter of the opening g. A tapered nozzle, h', is provided with a threaded end, h2, which screws into the perforation g, and between a shoulder ou it and the bottom of the tank is a packing, lr.

Secured within the nipples h, and surrounding the tapered nozzle h', is a glass tube, Around'this glass tube is fitted a cup-nut, h", which is threaded onto the outside of the nipple h, and is provided with a packing, h5. When this threaded cup-nut h"L is tightened up, the packing h5 is expanded laterally and tightly hugs the glass tube. The glass tubes near their lower endsl pass through the plate K, having downward-projecting nipples K', and secured to plate G by bolts k. The lower ends of tubes I pass into rubber balls L, and have secured thereon proper sieves or perforated plates, z. \Vithin the tubes are tapered perforated pipes J, having their small ends upward. Also within the tubes are fioating ball-valves I'. Secured to the pipe B below the valve B' is a bracket, b, which has pivoted IOO in its outer end an elbow-lever, one arm of which is marked b and the other b2.

In a nipple, g', projecting from the top of the tank G' is arranged a valve, g2, which is held normally closed by means of a spring. The cam f (see Fig. 4) is provided with two openings, f'f".

The operation of my machine may be described as follows, viz: The cans having been placed in position on the pan F, having been previously partially filled with solid material, and the tank D having been filled with the liquid, the plate G and its contents are lowered, bringing the rubber balls into contact with the cans. The further movement downward of the plate G and its attachments carries the plate E and the cans supported thereon into the tank D until the cans are fully irnm ersed in the liquid. The pump is now started, exhausting the air in the exhaust-tank A and all the parts communicating with it, includ-A ing the cans. As the air passes out of the can through the opening f' the liquid rushes in to take its place through the opening f2. The continual operation of t-he pump carries the liquid into the tube I, and when it is sufciently raised therein the floating ball-valves will be carried up until they lodge against the lower end of the tapered nozzles h', closing said nozzles. This fact may be observed through the glass tubeI, and when all the balls have been raised the further action of the pump will create a vacuum in the tank G', which will open the valve gl against the action of the spring, allowing the air to pass in, and thus relieve pressure on the valves I. Vhen the plate G and its attachments were first lowered, t-he valve B' was opened by the arm VZ22 of the elbow-lever striking the pro- 40 jections D5, and causing the arm b of said elbow-lever to press the stem Bl of the valve inward. After the cans have been filled, as before stated., the plate G and its attachments are raised until the stem of the valve g2 strikes the horizontal arm D7 of the projection D, pressing the valve farther open and holding it so. This will destroy the partial vacuum existing in the tank G' (the valvev B' having resumed its normally-closed position) and cause the liquid in the pipes I to escape at the bottom, whereby the valves I will again take their lower position on top of the perforated pipes J, as shown in Figs. 2 and 4.. The cans may now be lifted out of t-he liquid by raising their supporting-plate E, and removed therefrom. Anyliquid that may by accident have been drawn into the pipes B and Ais may be let out by opening the valve al.,

Having thus described my invention, what I claim isl. In a can-lling machine, the combination of a liquid-tank, a movable can-holder, an ex- -hausting apparatus, pipes communicating between the cans on the holder and the exhausting apparatus, and provided with valves, and mechanism for immersing the cans and their holder in the liquid in the tank, as and for the purpose set forth.
