FILLING-MACHINE.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed September 25, 1918. Serial No. 255,699.

To all 'whom 2f/may concern Be it known that I, AL'roN- VICTOR NEAL, a citizen of the United States, and resident of Hurlock, Maryland, have invented certain new and useful Improvements in Filling-Machines, of which the following is a specification.

My object is to provide a machine for lling receptacles with pulp with practically no waste of the material and with certainty-of a uniform till.

' The invention relates to that form of apparatus heretofore proposed in which the cans are passed into a tank, submerged in their course of travel therethrough to receiVe the pulp and are then withdrawn ,andi

passed onto a point of delivery, the whole action being performed automatically.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

Y In the accompanying drawings,

Figure lis a vertical sectional view of an organization embodying my invention.

Fig. 2 is a side view looking from the same point that the view of Fig. l is taken from.

Fig. 3 is a detail sectional view looking from the point in Fig. l this view showing a part ofthe feed Vwheel inrsection and the action of tipping the cans, thejview also includinga part of the trackswhich cooperate with the feed wheel in tipping the can bodies. Y

Fig. 4 is a view of the feed wheel in inclined position to perform its action in connection with the can bodies.

Fig. 5 is a side view of the feed wheel.

The invention involves introducing the cans into a bath 1 and lillingthem in their passage through the same. The canbodies are fedpdown by a track or .way 2, from a suitable elevated supply,roneafter another and in a horizontal position and just before they reach the bath they are turned up on end and fed through the tank, being submerged with their open end uppermost. As the cans rise from the-'bath they will have received the proper supply of the soup 0r material and they are then fed along a track 3 to the closing machine by a suitable sprocket chain, one of the dogs of which is indicated at 3. The amount of fill is determined by the incline of the track, or way, at

hehpoint where the can emerges from the The tipping of the can body at the point where it enters the bath is due to the shape of the track 2 along which the cans are propelled by a wheel 4. This wheel has propolling means or fingers 5, 5 on its outer side to receive and feed the can bodies along when they are turned upward, and it has a cam rib or flange 6 on its upper face which is inclined downwardly at a sharp angle at the points a inthe direction in which the wheel rotates. This rib inclines at a low angle at the points b, and at the points c, the rib at its upper edge is in a plane par allel with the plane in which the wheel rotates.

The track or chute for the can bodies consists of a number of metal strips or rods, two of which are at the rear, as at 7 two at the front as at 8 and .9, against which the cylindrical side of the can body contacts to be guided thereby as it falls from an elevated sourceof supply. There is also a rod or bar 10 to furnish a guide for the bottom of the can body and another rod 11 to furnish a guide for the top of the can body. A rectangular open frame is disposed at 12 to tie the bars together and hold them in their presmcribed relations.

At the point indicated generally at A Figs. 1 and 3 the bars or rods 8, 9, 10, 11 are bent or twisted so that the can bodies passing at this point will be turned up from a horizontal position to an inclined position, such as indicated at e. A. can body is also indicatedV at j in the act of turning from its substantially horizontal position to its inclined position ready to be submerged in the tank with its open top uppermost.

For propelling the can bodies along the track or way, which does the turning thereof, as just mentioned, I employ the wheel or disk referred to above. This is set in an inclined position with its 'lower end below the level of the liquid in the tank.

As the can bodies move down the chute they position themselves in front of the sharply inclined or curved edges a; of the wheel flange 6 and are propelled onward by the motion of the wheel in the direction of the arrow in Fig. 1 and in their onward movement they are caused to tip by the rails of the track or chute, as indicated at f and when completely tipped they rest with their bottoms on the rail 10 and are engaged by the walls of the recesses or pockets in the outer periphery of the wheel, which now take up the propelling action to force the can bodies around through the bath with their open top submerged, resulting in the pulp or liquid flowing thereinto, and eectf ing a lill.

The guide rails 8, 9, 10 and 11 are continued around the wheel concentric therewith to properly guide the can bodies, the rail 11 still serving as a guide for the top of the can body while the other rails 8 and 9 serve as guides by bearing on the cylindrical side. The guides continue around the wheel a suliicient distance to maintain control of the can bodies until they emerge from the bath and are delivered onto a suitable track,

platform or rail 3, which is elevated in respect to the tank level and when deposited here the lled can bodies are in upright position and can be taken away by any suitable feeding device which conveys them to the cover applying and closing machine. I have indicated conventionally at 14 such a conveyer consisting of a sprocket chain having dogs 3 to engage and propel the can bodies. The top edge portions c of the wheel act as means for cutting off the downward feed of the column of can bodies in the vertical or nearly vertical portion of the chute while a can body, such as at f is being propelled onward by the pushing wheel and tipped, as above described, by the bend in the chute. In Fig. 1 `the can body at f is stopped in its downward movement by the cut-off action of the cam rib at the point c while the previous can body 7 is being tipped and spaced apart from the following can 7. The low inclined portion Z) of the rib or flange will allow the can bodies to move down in front of the propeiling portion a but will prevent two can odies from getting in front of the same propelling portion a at the same time.

The inclined section of the track bar,

which guides the can bodies as they emerge this driving mechanism with the supports therefor are located above the tank 1 in which the cans are submerged and they are thus kept free from the material in the tank which might tend to corrode them, Y The track or chutemay be made of flat strips of metal capable of being bent and twisted or round wire rods may be employed. The can bodies when first introduced into the bath will float but the upper rail 11 will control their position, as shown at position e. In associating this filling apparatus with a can cover seaming or closing machine the can bodies as they leave the apparatus are fed directly to the closing machine by the feed chain 1&1. No additional spacing or timing means is required, the wheel 4 pushing the can bodies into linewith lthe dogs 3 of the sprocket chain so that no empty spaces occur here and the closing machine will be fed to work to its highest capacity.

Timing or spacing devices have been used heretofore between the filling machine and the closing or seaming machine which applies the covers to the cans, but these do not machine, representing a decided money loss.-V

VVith my machine this loss is prevented, each pocket of the pushing wheelbeing supplied with certainty and therefore each dog on the feed chain leading to the closing machine will be filled and the full capacity of the closing machine thus will be secured. The closing machine may be of any desired type. In some forms of machines the cans with their contents are brought to a seaming sta-- tion where the covers are applied and double seamed and for perfect operation thecan bodies should be fed in proper time and properly spaced apart to this station, so that at each operation of the seaming mechanism a can cover will be applied, butswith some timing mechanism as used heretofore the supply of can bodies to the seaming mechanism is irregular and hence the loss in product and hence, also the advantage exists in my filling apparatusnamely, that it serves not only to fill the can bodies but to time and space them to be delivered in regular order and without missing to the seaming head. Y

It will be understood that I have shown only one embodiment of my invention and that this is to be considered in an illustrative and not in a restrictive sense, the scope of my invention being defined by the appended claims.
