5 oiaims. (oi. 22e- 101) My present invention relates to can packing machines for packing iiaked fish and similar products into cans.y

One of the principal objects of this invention is to provide a can packing machine of this class which may be closely regulated for maintaining a desired un'formityl in the amount of fish or other products packed into a can.

Another object of this invention is to provide simple meansof varying' the quantities of fish or other products to be packed into cans.

Another object 'also isk to provide a packing machine of this class whereby the product to be packed is compressed before and while it is theultimate container or can. A further object of this invention is to provide a machine of this class for rapidly packing cans, and also packing them with a minimum of waste. An object also of this invention is to provideI a novel, simple, and economical method of packing cans. -5

With these and other objects in view as will appear hereinafter, I have devised a can packing machine having certain novel features of construction, combination, and arrangement of parts and portions, for packing aked iish or other products, as will be hereinafter described in detail, and particularly set forth inthe appended claims, reference being 'had to the accompanying drawings, and to the characters of reference.

thereon, which form a part of this application, in which:

Fig. l is a side elevational view of my can Vpacking machine in one form of construction,

portions being broken away lustration; i

Fig. 2 is a transverse 2-2 of Fig'.3;.

Fig. 3 4is a fragmentary front elevational view to facilitate the' ilsectional view taken at Fig. 4 isa fragmentary plan view thereof and, Fig. 5 is a fragmentary sectional view in plan, taken at 4-4 of Fig. 2.

My can packing machine may be mounted` frame l. On top of the frame is turntable which consists of a star lhaving can receiving recesses 2a,

upon a unitary mounted a can feed 4wheel .2, and thereabove a openings Ba'spaced 'edually from each other and the revolution of the turntable. These openings are axially aligned with theirecesses 2a. Below the turntable, and at least at the rear portion thereof, is a can support consisting of an open track 4 on which `the cans are carried by the perforated cutter disc 3, having n yit) ' through bevel `shaft is a ratchet 53 which is rotated by a pawl rill which meshes lower end of the cylinder is open Above the track and outwardly from the feed wheel is a circular can guide 5, which retains the cans within said recesses and below and in line with said openings.

The turntable and other mechanisms of the machine are operated by a motor l l. This motor rotates a sprocket l2 by a chain I3. To the sprocket, and axially aligned therewith, is a gear with a gear l5 mounted on a shaft I3. On the shaft is a sprocket I1 which operates, by a chain I8, a sprocket i9 mounted on a shaft 23. O-n this shaft is mounted a crank 2|, which is connected by alink 22, to the end of a rocker arm 23, pivoted on a shaft 24. On one end of the shaft 2d is a ratchet 25 which is actuated by a pawl 26 pivotally mounted on the rocker arm. 0n the opposite end of the shaft 24 'is mounted a bevel gear 2l which meshes with another bevel gear 23, which is connected to the ,lower vend of the turntable consisting of the star feed wheel 2 and the cutter disc 3. By such operation the turntable is rotated intermittently. In line with one of the perforations of the cutter disc, that is, when the turntable is at rest, and preferably at the rearmost perforation, is a compressing cylinder 3i, which extends vertically above the cutter disc. This cylinder is supported in the manner stated by a suitable support, such as by supporting rods 32. The intermediate portion of this cylinder has an inlet opening 3l'ad at its rear side for receiving the product to be packed through a tube 33 from a hopper 34. The and provides the discharge opening 3i".

In the cylinder is reciprocally mounted a plunger 35 which is reciprocated by a crosshead 33 supported on and guided by the rods 32. An adjusting screw 31 connects the piston tothe crosshead so that the position of the piston may be readily adjusted relative to the crosshead. From the `ends of the crosshead beyond the rods 32, extends vtrunnions 35*ab which are pivotally connected by links 38 to crank pins 332L of cranks 39, which are mounted on the opposite ends of the shaft IB. l

The hopper 3ftr is provided with a feed screw 4I at the lower portion and diverges upwardly to an open upper portion. This feed screw is preferably rotated intermittently,'through

gears

42, 43, and 44, by a shaft 45. This shaft has a sprocket 46 which is operated by a chain 41 from a sprocket 43. The latter sprocket is mounted on the shaft 49 which is connected to a shaft 53 gears 5| and 52. On the latter 54, mounted on a rocker arm 55, pivoted on the shaft 50. 'I'he free end of the arm is connected by a link 56 to the crank pin 39a of one of the cranks. In this manner uniform rotation is transmitted intermittently to the feed screw.

The

gears

42 and 44 may be two series of step gears which may be variously connected by an idler gear 43 for changing the speed of the feed screw. That is, the small gear of the series 42 of the plunger, as stated, permlts the cutting operation of the cutting disc 33 without interference by the plunger 35. As the turntable is robracket 63. tion, clear of which is reciprocally in a bearing 66a. On which is adapted to be enmounted at its lower end the rod is a stop 66b means of a screw 68, downward movement varied.

The open track product which does may drop from the 4 for the cans, permits the not enter the can, or which iiakes. Diiculty has heretofore been encountered, when attempting to pack sh flakes in securing uniformity of Weight of the sh in consecutive cans. I have solved this diiculty by compressing the sh akes to a certain density be handled as a solid, and then a suitable oil, liquid, or flavoring, may be added above the product compressed in the can.

Though I have shown and described a particular construction,

pended claims.

I claim:

l. In a machine of the class described, a cylinder having a discharge opening at one end inlet opening spaced backwardly from product feeding means communicating w1th the inlet opening of the cylinder, a

ing through the discharge opening, as the cutting means is moved by the conveyor.

2. In a machine of the class described, a cylinder by the conveyor.

4. In a machine of the class described, a cylinder having a discharge opening at one end and an inlet opening spaced backwardly from said end, a product feeding means communicating With the inlet opening of the cylinder, a plunger reciprocally mounted in the cylinder and movable therein from the inlet opening toward the discharge opening lbut terminating short of the latter opening, for compressing and forming in the cylinder the product to be packed and forcing said compressed product therefrom, means at the discharge opening for supporting an open packing can, and means at the discharge end o the cylinder for cutting off the portion of the compressed product extending through and beyond the discharge opening.

5. In a machine of the class described, a cyl-` inder having a discharge opening at one end and an inletopening spaced backwardly from said enda product feeding means communicating with the inlet opening of the cylinder, a plunger reciprocallyT mounted in the cylinder and movable therein from the inlet opening toward the discharge opening but terminating short of the latter opening, for initially compressing and forming in the cylinder the product to be packed and forcing said compressed product therefrom, means at the discharge opening for supporting anopen packing can, means at the discharge end of the cylinder for cutting off the product extending through and beyond the discharge opening, and means for subsequently pressing the Whole of the upper portion of the product into the can below the upper rim thereof after being placed therein by the plunger and cut off.
