AUTOMATIC-VACUUM CAN-SEALING MACHINE.

SPECIFICATION forming part of Letters Patent No. 736,978; dated. August 11, Application filed July 10, 1902- Both-1N0- 114,980. Illo model.)

To all whom it may concern.-

Be it known that I, JOHN G. HODGSON, a citizen of the United States, residing in Maywood, in the county-of Cook and State of Illinois, have invented a new and useful Improvement in Automatic Vacuum Can-Sealing Machines, of which the following is a specification.

My invention relates-to improvements invacuumizing-machines for sealing and securing covers on cans or vessels-that is to say, to

' machines for exhausting the air from cans or vessels and from. a receiver containing the same and then seating the cover on the can or vessel and restoring the atmospheric pressure to the receiver, whereby the cover is sealed and secured to the can or vessel by the atmospheric pressure.

The object of my invention is to provide a machine of a simple, eflicient, and durable construction by which this work may be automatically, rapidly, and cheaply performed,

My invention consists in'the means I employ to accomplish this result-that is to say, it consists in the combination, with a con- 1 tinuously-moving carrier having a plurality or series of seats for the cans or vessels, a series of individually movable 'or opening and closingmeceivers mounted on the carrier and mechanism for automatically opening and closing the exhaust as th'ecarrier moves.

It also consists in the combination, with a movable carrier having a plurality of seats for the cans and a plurality of receivers mounted thereon, of means for automatically feeding or delivering the cans or vesselson the carrier.

It also consists, in combination with the foregoing, of means for automatically discharging the cans. from the carrier.

4 It also consists in the novel construction of. parts and devices and in the novel combinashowing the valves for opening and closing the exhaust. Fig. 4 is a detail side elevation showing the mechanism for feeding and discharging the cans. Fig. '5 is adetail vertical sectional view through one of the receivers. Fig. 6 is a detail elevation showing the cam for operating the receivers, and Fig. 7 is a detail elevation showing the cam for operating the cover-sealing plates, and Fig. 8 is a detail view showing the cam for operatingthe valves controlling the communications between the receivers and the exhaust.

In the drawings like letters of reference in-.

dicate like parts in all the figures.

In said drawings, A represents the frame of the machine, *A an exhaust mechanism of any suitable kind, preferably a vacuum pump, and A an exhaust-chamber, the same being preferably formed in the pedestal portion of the frame.

B is a movable carrier, preferably a rotary turret or wheel, furnishedwith a plurality of seats I), having pins or devices b for registering the cans or vessels with the receivers. The carrier B is continuously rotated from the drivin -shaft 0 through the worm G thereon and worm-gear B on the carrier. on the carrier B are aseries of vertically reciprocating or opening and closing receivers 1), each having a packing-ring d at its open lower end 'for closing and sealing the same against the can-seat b of the carrier. Each of the receivers D is furnished with suitable guides d, reciprocating on suitable guides d on the carrier B to guide the up-and down movement on the receiver. Each of the receivers D isfurnished with a movable cover- Mounted seating plate F for properly seating the covers on the cans or vessels after the air has been exhausted therefrom; The sealing-plate F is preferably furnishedwith a rubber cushion or elastic plate f, interposed between it and the cap-plate f, to'which the stem f is attached, by which the seating-plate is operated or reciprocated, said stem extending through a stuffing-box d, with which the receiver D is furnished. The receiverD is reciprocated or opened and closed, as required, as the carrier rotates, preferably by a stationary cam D on the frame of the machine, through the connccting-lever D which is furnished with an antifrietion-roller d and with a forked end (1 having slots d engaging pins (1 on therecciver. The operating-levers D -one for each receiverare journaled on brackets B on the carrier B. I

Leading to each of the receivers, preferably through the calrseats b, which close the same, are pipes g, communicatingwith the exhaust device A through the valves G, which control the communication, said valves G- having an exhaust-port g and an air -inlet port g through which air may be admitted to the receiver to break the vacuum after the covers have been seated on the cans or vessels, and thus seal and secure the covers in place by a vacuum or atmospheric pressure seal. The inlet-ports g in the valves G communicate with air-inlet which are mounted on the carrier B. The frame A has a central standard or shaft A forminga bearing for the journal B of the carrier B and provided with an annular groove or channel a, communicating with the exhaust-chamberA", and the journal B is prefcrab] y furnished with a corresponding annular groove or channel 12 communicating with the pipes g, which lead to the receivers, and in which pipes the valve-shellsG and valves G are inserted. The valves G are automatically operated or reciprocated as the carrier B rotates, preferably by a stationary cam G which the valve-stems G3 engage. The valve-stems G may be furnished with springs G for moving them in one direction.

The cover-seating plates F are operated or reeiprocated as required, preferably bya stationary cam F on the frame of the machine engaging the operating-stems fof said plates. The cans are automatically fed ordelivered onto the can-seats b of the carrier B from the eonveyer-belt K by a movable feeder H,-having a series of can-pusher arms h, which engage the cans and move them along a curved guideway H onto the carrier B against the registering devices or pins b of the canseats. 'lhe feeder H is preferably given a rotary movement in cooperation with the continuously-rotating carrier by means of operatingarms hf on the feeder, which engage pins or projections b on the carrier B, or any other suitable gearing may be employed for connecting the feeder with the carrier.

As the carrier B rotates the cans are automatically discharged therefrom by a can-discharging arm M, projecting in the path of the cans, the same operating in conjunction with the guide M to deliver the cans upon the can-discharging eonveyer or belt N, which travels upon a suitable pulleyfN. The cant'eed eonveyer or belt K travels upon a pul- Icy K. A plate H flush with the eonveyerbelt K and carrier B, supports the cans as they are moved by the feeder H from the eonveyer K to' the carrier B. A similar-plate N flush with the conveyerNand carrier B, bridges th 0 ports 9 in the valve-shells G,

space between the carrier and said belt or con- The exhaust-pipes g are preferably furnished with regulating-valves g.

The operation is as follows: The cans X on the feed-eonveyer K are continuouslycrowded against the guide H veyer, so that one of the position to be engaged by cans is-always in 'one of the feederarms h as the feeder H rotates, and thus be onto the can carcarried by the feeder-arm rier B and against the registering pins or devices b of a can-seat b, the receiver D being at this time in its raised position. As the carrier B continues its rotation the receiver I) is closed down against the can-seat b by" the operating-cam D, and then the valve G is moved by the cam G to open the communication between the receiver D and the exhaust A through the intermed ate exhaust-chamber A the exhaust communication remain ingopen for about of the carrier, thus giving ample time for thoroughly exhausting the air from the receiver and the can audits contents, the cover X being at this time simply loosely in place on the can or vessel X. After" the air has thus been exhausted from the can and its contents thecover-seating plate F is next forced down by its operating-cam F,-thus seating the cover firmly and evenly on the can and compressing the packing a: between the seaming-fian'gesw w of the canand cover and holding the same thus compressed until the vacuum is broken and the atmospheric pressure restored to the receiver, when the cover will then be hermetically sealed and secured to the can by the vacuum or atmosphericpressure seal. As soon as the cover is thus seated on the can by the operation of the coverseating plate F the can Gr permits the valve G to be moved in the opposite direction by the at the end of said contwo-thirds of the rotation spring G and thus close the communication a between the receiver and the exhaust and open the communication between the receiver and the atmosphere through the air-inlet ports g g. As soon as this is done the receiver is again raised I), the seating-plate F being also lifted by its cam F. Then as the carrier B continues to rotate the can, now having its cover sealed and secured thereto by a vacuum or atmospheric-pressure seal, is automatically discharged from its carrier by the guide M and delivered upon the The'operation thus o'necan and receiver simultaneously takes place for the'others, so that a continuous discharge-eonveyer N. described in respect to.

by operation of the cam stream or series of cans pass onto, through,

and off of the machine, and continuously without stop or interruption. By this means the cans or vessels may be vacuumized and their covers hermetically sealed and secured thereto, each by a vacuum or atmosphericerally-open can-seats to receive the cans horiof reciprocating receivers mounted on the carrier and having op'en lower ends engaging the can-seats and thus inclosing and surroundihg the cans, and
