To all whom it may concern: I

- Be it known that I, CHARLES I-I..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.

My invention relates to can filling machines and more particularly to means for agitating the materials and compressing them into the cans. Mechanism which is designed for use in canning granular materials may not function equally well with comparatively bulky material such as tomatoes or comparatively soft. materialsuch as string beans. p

The objects of my invention are to provide improved means for agitating comparatively bulky or-soft materials and compressing vthem into, the.v measurlng devices, and to provide such means which are readily adaptable for use with granular materials.

These objects, and other advantageous endswhich will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which I Figure 1 is a plan view of a canning machine embodying my invention,

Figure 2 a vertical section through the hopper and turret, v

Figure 8 a plan view of the hopper plate,

Figure 4 an enlarged fragmentary section on line 4-4 of Figure 1 showing the hopper and hopper plate at one limit of its oscillatory movement,

Figure 5 a like view showing the hopper and hopper plate at the limit of its swing in the opposite direction,

Figure 6 a reversed plan view of a part of the hopper plate, I

Figure 7 a section on line 77 of Flgure 1, showing the hopper plate and shaker mechanism, the other parts being omitted, and

Figure 8 an end view of the shaker mechanism.

Referring to the drawin s, 1 indicates the hopper and 2 thehopper p ate which is provided with an upwardly extending flange 3 to the upper part of which the hopper is secured. The part of the flange below the hopper has a shouldered enlargement 4 in which is secured a compression member 5 of ber.

;structure 14 at its outer end, the top rubber or other'elastic material. The inner wall of the compresslon member 18 curvedat its upper and lower edges and slopes outlower curved edge. The hopper plate preferably has a curved upwardly extending groove 6, having a; perforated top, extending from flange 3 to a point over the discharge wardly from the upper curved edge to the port 7 of the turret 8, and communicating I with the space within the compression mem- 3 This groove serves to convey granular material, which might otherwise be crushed,

to the discharge openingand also serves as an air vent. canning bulky or soft material-the inner end of the groove may be closed by a detachable plate 9.

Axial oscillation of the hopper is effective I When the'machine is in use for with granular material but not so effective that a swinging oscillation is equally or more with more bulky material and I have found efiec'tive with both classes of material. I

therefore provide means for imparting a swinging oscillation'to the hopper plate and 1 hopper. For this purpose I position one end of the hopper plate'upo'n aboss 10 extending from'the frame and yieldingly con- 'nect ittherewith by a pivot pin 11 and a spring 12." The opposite end'of the hopper plate carries a bracket 13 having-abox like which is provided with a longitudinal slot p 14 and the bottom with a like slot indicated at 15. The interior of the box houses "a block 16 which is slidable therein, and the box rests upon a wheel 17 adaptedto berotated by any suitable mechanism. Wheel 17 carries an upwardly extending eccentric pin 18 which takesthrough slot 15, block 16 and slot 14 and is yieldingly held to the box by a spring 19; Rotation of wheel 17 causes the hopper plate to oscillate with pivot pin. 1

11 as the axis of oscillation.

I have illustrated the measuring wheel as ,j I

consisting of telescoping sections 20 and 21,

section 20 being supported by a bed plate 22, andthe two sections being adapted to be rotated by means of a shaft 23 carrying a dog 24 disposed in an oblong opening 25in embraced by an inwardly threaded band28 by rotation of which the telescopingsections may be adjusted to vary the capacity of the measuring receptacles.

The operation will be best understood by reference to Figures 4 and 5 of the drawings, it being understood that the hopper is filled and the shaker mechanism inlop+ eration and the hopper and compression member thereby caused to swing to and fro 7 over the measuring receptacle which is be ing charged. Figure 4 shows the measuring receptacle partly filled and the hopper at the limit of its throw to the left and Figure 5 shows it at the limit of its throw to the right. As it moves from left to right the part 'of the sloping compression member at the left exerts a w'edging pressure tending to press the fruit inwardly and downwardly into the measuring receptacle as shown in Figure 4. As the hopper is swung from right to left the part of the sloping compression member at'the right tends to press the fruits inward and downward and the fruits are gently and snugly packed into the measuring receptacle. v

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence :I do not limitmyself to'theprecise construction set forth, but consider that I am at libertyto make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is 1. In a can filling machine, the combination with traveling measuring receptacles of a plate carrying a hopper and having a pivot, ad1acent one edge, connecting it wlth the frame, and means for swinging the plate to and fro, with the discharge opening of the hopper over the measuring receptacles, with said pivot as an. axis.

2. In a can filling machine, a plate carryin a hopper and a yielding jcompression mem ber disposed under the throat ofthe hopper. Y

3. In a can filling machine, a plate. carrying a hopper and a yielding compression member disposed under the throatofthe.

hopper,.the compression member having its interior wall sloping downwardly and out wfardly. I

4:. In a can filling machine, a plate carrying a hopper and a yielding compression member disposed .under the throat of the hopper, the compression member having its interior edges curved and its interiorwall sloping downwardly and outwardly.

5. In a can filling machine, the combination of traveling measuring receptacles, a plate carrying a hopper and mounted to swing to and fro with the discharge opens ing of the hopper over the measuring receptacles, and a yielding compression member disposed under the throat of the hopper.

6. In a can filling machine, the combination with traveling measuring receptacles of a plate carrying a hopper and having a pivot, adjacent one edge, connecting it with the frame,'a yielding compression member disposed under the throat of the. hopper, and
