CAN-l-ILLING MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 516,326, dated March 13, 1894. Application filed March 1, 1893. Renewed February 5, 1894- Serial N0. 4:99.210. (N model.)

To all whom it may concern.-

Be it known that we, HARTLEY C. BAXTER, of Brunswick, and HENRY R. STICKNEY, of Portland, county of Cumberland, State of Maine,

have invented new and useful Improvements in Can-Filling Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists in an improved organization of a machine which is convenient and efficient in its operation, and passes the cans to the filler,injects sirup into the cans in transit, wipes the tops of the filled cans and r5 stirs the contents of the cans by means of a single lever operated by the person in charge of the machine, all as hereinafter more fully described and set forth in the claims.

In the annexed drawings Figure lis an end elevation of ourimproved can-filling machine showing its connection with the cooking apparatus. Figs. 2 and 3 are side elevations of said can filling machine showing the same in two of its operative positions. Fig. tis atop 2 5 plan view of the same. Fig. 5 is a vertical transverse section of the stirrer taken online at, w, in Fig. 3, and Fig. 6 is a vertical transverse section of the can-lifter taken on line y, y, in Fig. 4.

Similar letters of reference indicate corresponding parts.

A represents the filler which is attached to the end of the cooking cylinder -B which may be of any suitable and well known con- 3 5 struction, preferably of the form shown in the Patent No. 202,979, granted to Edward P. Bates, April 30, 1878. Said cylinder being provided in its interior with a spiral conveyer which forces the cooked substance into the filler, which latter is also in this case provided with a vertical spiral conveyor, not necessary to be here shown, by which conveyer the cooked substance is forced from the filler into the can placed under the discharge spout of the filler. Beneath the filler and extending laterally therefrom is the can-guide aover one end of which is arranged a ring or suitable can-chute -afor the reception of the cans to be filled. Under said can-chute is the can-pushing bar -b which is movable 5o lengthwise of the can-guide 'a and is provided on top of its outer end portion with a platform bby which it supports the cans in the chute a while said bar-b pushes the bottom can from under the chute and toward the filler. Said platform has on'its side facing the filler a downwardly extending shoulder b" by which it pushes the cans as aforesaid.

Directly under the filler A is the canlifter -cwhich raises the can from the canguide sufficiently to cause the discharge spout of the filler to enter into the opening in the top of the can and charge the can with the cooked substance. Said can-lifter is held normally with its top flush with the top of the can-guide, by means of a spiral spring c' surrounding the downwardly extending stem c of the lifter and bearing with its opposite ends respectively against the under side of the can-guide and against a collar attached to said stem.

The described can-pushing bar b and can-lifter c are both operated by means of one and the same lever -O which is operated by the person in charge of the machine and also actuates all other mechanisms of the machine as hereinafter explained. The lever -O is pivotally mounted on a shaft D extending across the machine some distance beneath the can-guide 'aand I journaled in brackets D- rigidly attached to or integral with the bottom of the canguide, which latter constitutes part of the frame of the machine.

To the shaft D- are fastened two rockarms FF- which are thus pivoted in common and caused to move in unison. The rock-arm F is extended upward and pivotally connected to the can-pushing bar -b' at which point the lever, 0, is provided with two bearings 0, 0, for engaging said arm. The other arm F is extended under the stem c" of the can-lifter and adapted to force the same upward and thus raise the 5 same to bring the mouth of the filler into the top opening of the can as hereinbefore stated. There is a sufficient playorlost motion between the arm F and stem cto allow the other rock-arm -F to move the push-bar -h back to its extreme outer position without raising thelifter to an excessive elevation. e also utilize one of said rock-arms, preferably the arm F, for operating the piston of the sirup-pump 1" which has its discharge nozzle P over the can guide a between the can-lifter c and can-chute a. Said pump piston deriving motion from said rock-arm by a pitman -R, which is connected to said arm adjustably lengthwise thereof, so as to allow the thrust of thepump piston to be regulated according to the amount of sirup desired to be introduced into the cans. Said adjustable connection may be made in various ways and is shown in the form of a longitudinal slot -F- in the rock-arm receiving through it the bolt by which the pitman is connected to said arm.

To regulate the thrust of the rock-arm F- so as to prevent it from moving the can-pushing bar b beyond the desired distance toward the filler, we attach to the frame a set-screw -for other suitable adjustable stop in the path of the said rockarm.

Beyond the filler A- is a can wiperd arranged to sweep across the top of the filled can and clean the same. Said can wiper is pivoted to a bracket -I erected on the frame of the machine, and swings in a horizontal plane and in an are extending transversely over the can-guide. The said canwiper has extending from it an arm dwhich is connected to a two armed lever-epivoted to the frame of the machine. To a post -gon the bracket I is connected the upper end of a spiral spring q', the lower end of which is attached to a sleeve, K, sliding on said post and connected to the horizontal arm of the lever -e which is thereby drawn upward and caused to hold the wiper (Z in its normal position. To sweep said wiper across the top of the can we connect the vertical arm of the lever 1 to the manually operated lever O by a rod --ewhich passes freely through an eye in a stud-pin e-- attached to the lever C and has adjustably secured to its outer end a collar e"- which is set in such a position as to permit suflicient lost motion between the rod and lever to leave the wiper dormant during the first part of the rearward movement of the lever C and only actuate the wiper during the latter part of said movement of the lever which at the same time lifts to the filler the empty can broughtdirectly under it by the pushing bar b.

h denotes a stirrer which is arranged beyond the wiper and movable vertically to enter into the filled can and stir the contents thereof and subsequently withdraw therefrom. Two of such stirrers may be employed if desired, as shown. We prefer to construct said stirrer of a horizontal disk h' pivoted in and extending through the base'of the bracket I- and rigidly attached to a vertical shaft -tand pivoted at its upper end to the said bracket and provided with a pulley jupon which runs the belt -j'-, by which rotary motion is imparted to the shaft 2'. The body of this shaft from the disk h to the journal of the shaft is squared or otherwise made angular and upon the same slides vertically a collar -i' to which are fastened the stirring wires hwhich pass freely through apertures in the disk h and are preferably united or formed in one piece looped beneath the disk as represented in Fig. 5 of the drawings. The collar-z"- is connected to the before described sliding sleeve -7a and the stirrer is thus also sustained normally in its raised position by the spring gand actuated simultaneously with the can-wiper d.

The operation of the described machine is as follows: The cooker -B being in operation forces the cooked corn or other sub stance into the filler A. The empty cans u 3 uto be filled maybe placed either singly or in a tier upon the platform l) of the pushing bar b-, the bottom can being surrounded by the ring a'. Then by swinging the lever C to the rear as represented in Fig. 2 of the drawings the platform --b' is withtlrawn from under the cans which then.

drop onto the guide a. The operator then throws the lever O forward and causes the bearing 0- thereof to engage the rock-arm F- and push the same forward as shown in Fig. 3 of the drawings. Said rock-arm carries with it the baribwhich pushes the bottom can to a position directly under the discharge-nozzle P- of the sirup-pump. In said movement the platform b passes under the remainder of the tier of cans and supports the same. The operator then draws back the lever C- to its extreme outer position, another can is thus allowed to drop onto the guide aand pushed forward by the next forward motion of the lever. Each can thus introduced into the machines pushes along the cans in front of it, and in this manner the cans are passed successively to the nozzle P-, lifter -c, wiper (Z and stirrer h. The rearward movement of the lever -C operates the pump P by the rock-arm --F- and pitman R- so as to force sirup into the can standing under the nozzle P' and at the same time the rock-arm F pushes up the lifter cso as to cause the discharge spout of the filler A to enter into the opening of the can seated on the lifter, and the wiper is drawn across the top of the filled cans and the stirrer entered and rotated in the farthest filled can by the lever C- drawing back the rod -e. There is sufficient play between the bearings 0-0' to allow the lever O to be swung forward a sufficient distance to release the rod e and allow the wiper d and stirrer -h to resume their normal positions before causing thelever to actuate the can pushing bar b by the rock-arm F.
