T0 to whom it may concern:

Be it known thatLEDWIN NORTON, a citizen of the United States, residing in New York, in the countyof New York and State of New York, have invented a new and useful Improvementin Vacuumizing and Double-SeamiugMachines, of which the followingisaspecifioation.

My invention relates to machines for vacuumizing cans and seaming the covers thereon.

The object of my invention is to provide an automatic machine of a simple, efficient, and durable construction by means of which sheet-metal cans or vessels may be automatically, rapidly, and cheaply vacuumized, hermetically sealed, and thecovers thereof double-seamed thereon.

My invention consists in the means 1 employ to practically accomplish this resultthat is to say, it consists, in connection with a continuously-moving carrier having a pinrality of seats thereon, each adapted to receive and support a single can or vessel, of a plurality of individually-movable opening and closing receivers mounted on the carrier, an exhaust mechanism and means for automatically opening and closing the exhaust to each receiver as the carrier moves, a doubleseaming head inside each receiver having a plurality of successively-operating doubleseaming rollers, means for automatically feeding or delivering the cans one by one upon the can-seats of the carrier and for au tomatically discharging the cans therefrom after they have been vacuumized and the covers double-seamed thereon, and means for operating the receivers and other parts in proper succession to first close the receiver exhaust the air therefrom and from the can therein and its contents, then force the seaming-head down upon the cover of the can to compress the packing interposed between the can and its cover, and thus seal the can in vacuo or while the vacuum is maintained in the receiver, then admit air to the receiver, and open the receiver by withdrawing the receiver from around the can while the vacuu mized can remains clamped by the seaminghead, and then finally after the receiver is withdrawn from the can so that the seaming operations and seaming-rollers may be under inspection to successively operate the doubleseaming rollers and seam the cover to the can and discharge the vacuumized and seamed can from the machine.

My invention also consists in the novel construction of parts and devices and in'the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a combined vacuumizing and double seaming machine embodying my invention. Fig. 2 is a central vertical longitudinal section. Fig. 3 is a horizontal section on the broken line 3 3 of Fig. 2. Fig. 4 is a horizontal section on line at t of Fig. 2. Fig. 5 is a detail elevation of the can-feed mechanism. Fig. 6 is a detailed section on line 6 6 of Fig. 2. Fig. 7 is an enlarged detailed central vertical section through one of the receivers. Figs. 8 and 9 are enlarged detail central vertical sections of one of the seaming-heads, showing the seaming-rollers in different positions. Fig. 10 is a horizontal section on line 10 10 of Fig. 8, and Figs. 11 and 12 are detail sectional views of the can before and after the seaming operation.

In the drawings like letters of reference indicate like parts throughout all the figures.

In said drawings, A represents the fram of the machine.

B is a continuously-moving carrier, preferably a rotary turret or wheel, furnished with a plurality of can-seats Z), having registering pins or devices b for registering the cans with the opposing chucking or clamping disks cl of the seaming-heads D, which arelikewise mounted on the carrier above the can-seats b, so as to clamp the cans between them.

C C are a plurality of individually or independently movable vacuum-receivers, each preferably bell-shaped or open at its lower end and mounted on the rotatable carrier B. Each of the receivers C is furnished at its lower end with an elastic or rubber packing c to close and seal the receiver tightly against the can-seat I) of the receiver B, the can-seat being preferably a portion of the horizontal plate B of the carrier. If desired, the canseat I) may have an inserted thin disk of rubber b to compensate for slight inequalities in the heights of the cans. Each of the receivers O is furnished with suitable guides, as C, reciprocating on corresponding guides (J on the carrier B to guide the up-and-down movement of the receiver. Each of the receivers O is furnished with a stuffing-box 0 through which the operating-shaft D of the seaming-head D extends. Each of the receivers O is reciprocated or opened and closed, as required, as the carrier B rotates preferably by a stationary cam O on the frame of the machine through the connecting-lever G which is furnished with antifriction-roller C and its opposite end with forks C and links C pivotally connecting the same with the receiver 0. These operating-levers for reciprocating or moving up and down the receivers are journaled on brackets B on the carrier B.

Leading to each of the receivers C, preferably through the can-seat b, which closes its open end, is an exhaust-pipe E, communicating with the exhaust device E through pipe E and the valves F, which control the communication, the valve-shells F of said valves F having each an eXhaust-portfand an inlet-port f, through which latter air may be admitted to the receiver to break the vacuum after the cover has been seated on the can or vessel by operation of the clamping-disk d of the seaming-head D in each receiver. Corresponding ports in the valves F communicate with the ports ff in the valveshells E, which are mounted on the carrier B. The frame A has a central standard or shaft A forming or having a bearing A for the journals or hub I3 B of the carrier B and provided with stufling-box connections a a with said carrier. The exhaust-pipe E leading to the exhaust device E, communicates, through a channel a in the sleeve or hearing A, with a chamber a, which has a communication b through the hub B with a chamber b in said hub B into which lead the exhaustpipes E, which extend to each of the receivers and in which pipesE the valves F and valveshells F are inserted. The valves F are automatically operated or reciprocated as the carrier B rotates preferably by a stationary cam F secured to a stationary upright shaft or post A which cam the valve-stems F engage as the carrier rotates. A spring F on each of the valve-stems moves the valve-. stem in the opposite direction.

' The seaming-head D inside each of the receivers (J is furnished with a can-clamping chuck or disk d, having a countersink or shoulder d to fit the countersink of the canhead :0 and cooperate with the double-seamon the vertically-reciprocating slide D with which each of the seaming-heads D is provided. The earns 01 d d are differently located on the slide D so as to successively operate the set of double-seaming rollers that is to say, as the slide D carrying these cams is depressed it first causes the first double-seaming roller d to engage the flange of the can-head and curl or fold the same partially around the seaming-flange on the head and can -body and then operates the next seaming-roller 01 which serves to further fold the seaming-flanges downward and together and then operates the pair of finishing-rollers d, which are alike and preferably should be operated simultaneously and serve to finish the seam and compress the folds thereof tightly together. The can-clamping chuck or disk (1 has antifriction or ball-bearing connection d (1 d with the seaminghead D, so that the chuck-disk d and the can may remain stationary or non-rotating while the seaming-head D rotates around it.

The seaming-head D has a spring connection D with the cam-slide D which latter cam-slide is directly secured to the rotating and reciprocating operating-shaft D of the seaming-head. This interposed spring D between the seaming-head and cam-slide causes the seaming-head D or the clamp-disk d, carried thereby, to first clamp and compress the cover at of the can X down upon the can after the air has been exhausted therefrom and from the receiver and to hold the cover thus sealed to the can while the vacuum in-the receiver is being broken and the receiver withdrawn from around the can and then by the further downward movement of the camslide D to operate the seaming-rollers as required. The interposed spring D permits the necessary further downward movement of the cam-slide to effect the seaming operation.

The seaming-head is preferably provided with a can-stripper or an ejector-disk c1 having an operating-stem (Z which extends up through the operating-shaft D of the seamerhead and through the guide-stud d with which the clamp-disk d is provided. The spring (1", connecting the seaming-roller-operatin levers d serve to retract the seam-- ing-rollers. The required up-and-down or reciprocating movement is communicated to the seaming-head shafts D as the carrier B rotates by a stationary cam D secured to the stationary shaft or post A of the frame and operating through connecting-levers D having antifriction-rollers D to engage the cams and forks D connected to the shaft D by adjustable collars D D". The ejectorstem 01 on each of the seaming-heads is op erated in one direction by a stationary cam D supported on the frame A, each of the stems (Z having a spring (Z to move the same in the opposite direction. The required rotary movement is communicated to each of the seaming-heads D or its operating-shaft carrier.

D as the carrier B rotates preferably by means of a spur-gear D one of each of said shafts D engaging a rotating gear D which isjournaled on the frame of the machine and which is provided with a bevel-gear face D, that meshes with a bevel-gear D on the driving-shaft D carrying a driving-pulley D The carrier B is provided with a shell B to give proper support to the various operatinglevers and parts carried thereby, and this carrier is rotated preferably continuously by a gear B thereon, which engages the worm B on a driving-shaft B The cans are automatically fed or delivered onto the can-seats b of the carrier B from the conveyer-belt K by a movable feederH, having a series of can-pusher arms 7t, which engage the cans one by one and move them along a curved guideway H 011 the carrier B against the registering devices or pins 17 of the can-seats. The feeder H is preferably given a rotary movement in cooperation with the continuously-rotating carrier by means of operating-arms h on the feeder, which ongage the pins or projections b on the carrier B, or any other suitable gearing may be employed for connecting the feeder with the As the carrier B rotates the cans are automatically discharged one by one therefrom by a can-discharging arm M, projecting in the path of the cans, the same operating in conjunction with a guide M to deliver the cansnpon the can-discharging con- Veyer or belt N, which travels upon a suitable pulley N. The can-feed conveyor or belt K travels upon a pulley K, and a plate H flush with the conveyor-belt K and carrier 13, supports the cans as they are moved by the feeder H from the conveyor K to the carrier 13. A similar plate M flush with the discharge-conveyer N and carrier 13, bridges the space between the carrier and conveyer N. The conveyers N and K are continuously driven from any suitable source of power.

The operation is as follows: The cans on the feed-conveyer K, having each its cover at loosely in place thereon, are continuously crowded against the guide H at the end of said conveyer, so that one of the cans is always in position to be engaged by one of the feeder-arms h as the feeder H rotates, and thus be carried by the feeder-arm onto the carrier 13 and against the registering pins or devices b of the can-seat b, the receivers G and the seaming-head D therein being at this time in their elevated or raised position. As the carrier B continues its rotation the receiver O is closed down against the can-seat b by the operating-cam C, and then the valve F in the exhaust-pipe is moved by its operating-cam F to open the communication between the receiver 0 and the exhaust E through the intermediate communicating pipes or passages. The exhaust communication with the receiver remains open for a portion of the revolution of the carrier, thus exhausting the air from the receiver and from the can audits contents, the cover a; during all this time remaining loosely in place on the can or vessel X. After the air has thus been exhausted from the can and its contents the seaming-head D, with its can-clamping disk 61, is next forced down by its operatingcam D thus setting the cover w firmly and evenly on the can X and compressing the packing 00 between the seaming-flanges x 00 of the can and cover and holding the same thus compressed untilafter the double-seaming operation is completed. The controllingvalve F is next again moved by its operatingcam, thus breaking the vacuum and admit-' ting air to the receiver, and then the receiver 0 is withdrawn from around the can through the action of its operating-cam, and then the cam-slide D is given a further downward movement through action of the seaminghead-operating cam D and the double-seaming rollers forced into engagement with the seaming-flanges of the can and coversuccessively, as before stated, and the seaming operation performed, the seaming-head D rotating continuously through its connectinggearing. As the carrier B continues its rotation the vacuumized, sealed, and doubleseamed can is discharged from the carrier 13 by the guide M and delivered upon the discharge-conveyer N. The operation thus described in respect to one can and one receiver and one seaming-head simultaneously takes place for the others, so that a continuous stream or series of cans passes into, 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 double-seamed thereon very rapidly and cheaply and also with great certainty and reliability, as the cans and the action of the double-seaming rollers are open to inspection during the double-seaming op eration, as the receivers at this time are withdrawn from around the cans.
