CAN-FILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 688,231, dated December 3, 1901.

Application filed August 7, 1901. Serial No. 71,123. (No model.)

To (all whom it may concern:

Be it known that I, CHARLES H. AYARS, a citizen of the United States, residing at Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Can- Filling Machines, of which the following is a specification.

This invention relates to machines for filling cans with vegetables, such as tomatoes or the like; and one of the objects of the invention is to provide a machine of this character with means whereby the empty tin cans will be successively fed while their sid es are in a horizontal position to the filling devices and then when filled will be automatically turned with their open tops upward and pushed onto a table.

Nith this and other objects in View the invention consists in certain constructions, arrangements, and combinations of the parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which-- Figure 1 is a side elevation of the can-filling machine. Fig. 2 is an enlarged top plan view of one end of the machine and illustrates the can holding, righting, and delivering devices, the can-receptacle being left off. Fig.

3 is a front end elevation of a portion of the machine with a portion of the can-receptacle shown. Figs. 4, 5, 6, and 7 are detail views of the can-righting device. Figs. 8 and 9 are detail views of the can-delivering device or pusher. Fig. 10 is an end elevation of the machine. Fig. 11 is a top plan view of the other end of the machine from that shown in Fig. 2 and illustrates the adjustable plunger.

Referring to the drawings, the letter A designates the machine-framework, on which is mounted a hopper a, adapted to hold the vegetables or other material and deliver it into a horizontally-extending tubular casing b,'and a horizontal plunger 0 reciprocates across the bottom of said hopper and forces the said material out of said casing into the can, as will be hereinafter more fully described.- 7 To the rear end of the said plunger 0, asshown best in Fig. 11, is rigidly secured a circular casting 0, having two rearwardlyextending slotted cars 0 A rod d is rigidly secured to said casting c and works through a bearing 61' on the rear end of the framework A, and a cross-head e is adjustably secured by bolts e to the slotted ears 0 of the casting c and is provided with an upwardly extending tongue 6 in which a set-screw f works. The advance end of said screw bears against said casting c.

The two oppositely-extending arms of the cross-head c are secured between the upper and lower bars of two horizontally-extending reciprocating frames g, located one on each side of the hopper a, and said arms abut against shoulders g on said framebars, whereby to limit any forward movement of the cross-head irrespective of said bars, and

are provided with lugs g to which one end of coil-springs 7i are fastened. The other ends of said springs are rigidly secured by bolts h to the forward ends of the reciprocating frames, as indicated in Fig. 1.

Projecting from the forward end of each reciprocating frame g is a fork 9 to each of which is pivoted one branch of a forked vertically-vibrating lever 'i, fnlcrurned on the lower part of the framework A, and as the said lever is moved by mechanism hereinafter described the said frames 9 are reciprocated and carry (through the medium of the cross-head e) the plunger 0 back and forth across the lower end of the hopper a and out of and into the casing 12. The tapering discharge end Z) of the casing b is opened and closed by a gate secured to a rod b moved up and down by a lever 5 It is sometimes necessary to change the position of the plunger 0, so that it will go farther or not so far into the casing b, and to do this the bolts 9' are loosened, the set-screw f is turned to adjust the plunger and its rod 01 with respect to the cross-head c, and the bolts 6' are again tightened when the desired adjustment has been effected.

In order to allowthe plunger to yield in its movement in case it has filled a can to its capacity before the lever t has completed its forward movement, the springs h are provided, said springs stretching and permitting the frames g to continue to advance slightly irrespective of the advance of the cross-head.

At the tapering discharge end I) of the easing b is the usual plate b through which the vegetables are discharged and against which the open mouth of the can isheld while the can is being filled, and adjacent said plate is a can-receptacle j, in which a number of empty cans are to be placed, the cans resting one upon the other and being disposed horizontally or on their cylindrical sides with their open tops facing the gate in the said discharge-plate b of the casing 19. The lowermost can rests in a rocking cradle k, pivoted on a pin between two plates b, as shown best in Figs. 2 and 3, and to one side of said cradle is connected the upper end of a link m, whose lower end is connected to the free end of a vertically-moving lever on, forced upwardly by a spring m as shown in Fig. 1.

On the framework A at the lever side of the cradle lo and at the entrance end of a slideway ac is pivotally mounted a can-right ing, device n, in the form of a substantially rectangular box, as shown in detail in Figs. 4,5, 6, and 7, and open at one end, asshown at a, and provided with a rearwardly-extending arm M, to which one end of a link 0 is connected. The other end of said link is connectedto the cradle-rockinglink m, asshown in Eigs. l and 3, so that. the said cradle 70 and the-righting device it will move simultaneously.

A can-pusherp (shown in detail in Figs. 8 and 9) is mounted to slide back and forth on the upper surface of the frameworkA, with its;forward end p passing through the lower open end 'n of the righting device n, andthe rear endp ofisaid slidingpusher isadjustably connected to a plate q, provided with two spaced-apart lugs q, which-take one on each side of one of the branches of the plungerroperating lever has shown in Fig. 2, so that; the. pusher will be slid back and forth as=the said lever moves,

Eulcrumed between earsr in frolfit of the, cradle 1c is-a-clamping-arrn 1', provided at its; upper endjwith a disk or plate. 1, adapted to bebrought-into contact with the. bottom of a can on the cradle, whereby to clamp the can tightly against the dischargeend b of'the casing b-while the-can is being filled. Below-its with arrelatively large gear-wheel t, meshing with a small pinion-u on the main driving-.

shaft: to, which latteris driven by a pulley, .as; shown indotted lines, Fig. 10.

The plunger-operating lever r; is actuated from-the said transverse shaftt by means of a cam-w-heel t acting alternately on upper audlower beams 10 and :w, secured to said le- Vbrifrflt: their forward ends and connected 7 togetheratth'eir rearends, which are otherwise free', by ;means. of a link w The gate-slide lever 19 and clamping-arm lever sare moved upwardly by means of camsy y on said shaft, and the lever m for rocking the cradle 70 and righting device 'n is pressed downwardly against the tension of its spring m by another cam 21 on said shaft 25.

The practical operation of the machine is as follows: The empty tin cans are placed in the receptaclej on their sides-that is, turned down or tilted- -with their open tops in a vertical position and facing the discharge-opening of the casing h, and the parts of the machine are in the position shown in the drawingsthat is, the cradle 7c is in a horizontal position and the righting device it is in a substantially vertical position. As the shaft 15 rotates the gate is drawn down by its rod 19 and lever b the clamping-arm ris pressed against the bottom of the can restingin the cradle k and holds the open mouth of the can against the discharge-plate b ,and the plunger 0 is moved forwardly to fill said can. The plunger then immediately moves rearwardly, the gate at-once rises'to close the dischargeopening, the clamping-arm releasesthe can, and the lever m is moved downwardly, which rocks the righting device n to a horizontal position and tilts the-cradle 7c, sothat the filled can will roll'off the cradle into the righting device, and as the lever m moves upwardly again the cradle will be tilted back to receive another can, and the ri-ghting de vice will be moved to a vertical positionto place the can with its open top, uppermost,

while. at the same time the-lever hmoving forwardly to fill another can, will'movethe pusher p,.which will push. the filled can out of the-righting device and into the-slideway 00, which leads, preferably, to a topping and wiping machine. Asthe can rolls. off the cradle onto'the righting, device it its-open mouthwill face alongthe discharge-plate b and will lie against the top ofthe righting device, thereby preventingthe contents ofthe can from being spilled while the canais in the horizontal positionthat is, with its opentop sidewise,.

Having thus described my invention, what I claim asznew, and desire to secure by Letters Patent, is-* g 1. In a machine of the character described, can-filling mechanism; means for presenting a-can in a horizontal position, that is, with its open top sidewise, to said can-filling mechanism; meansfor rightingthe can after it has :been filled; and means for removing thecan from the, can-righting means.v
