HARRY VI. LOXVE, OF OMAHA, NEBRASKA, ASSIGNOE, BY MESNE ASSIGNMENTS, TO SPRAG'UE GANNING- MACHINERY (30., A CORTCRATION OF ILLINOIS.

FINISHING-MACHINE.

Application filed March 2 191?.

To all whom it may concern.

Be itknown that I, HARRY W. Lows, a citizen of the United States, residing at Omaha, in the county of Dt'iuglas and State of Nebraska. have invented new and useful Improvements in 1*inishing-h iachines, of which the followin a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to finishing machines and more specifically to finishing machines for catsup.

One of the objects of my invention is to provide an improved finishing ma chine for catsup, or the like, which will not force foreign Slll)t111(i6$. such as mold and the undesirable parts of the tomatoes such as the harder reen portions, through the screen, thereby insuring a smooth uniform high grade product. Further objects will appear from the detail description to follow and from the appended claims.

In the dra *ings in which one embodiment of my invention is shown:

Figure l is a vertical axial section through a finishing machine embodying my invention.

Fig. 2 is an end elevation of the machine viewed from the left of Fig. 1.

Fig. 3 is a plan view of the machine.

Fig. at is a detail sectional view showing the location of the brush with respect to the screen.

Fig. 5 is a section on the line 5-5 of Fig. 1.

Fig. (5 is a detail view of the spider which actuatcs the brushes.

Referring now to the drawings in detail, the finishing machine shown, comprises a perforated frusto conical screen 10 whlch may be of sheet brass, a nest of brushes, 11, pivotally mounted to operate in said screen, to force the material hrough the perfora tions of the screen, means 12 for. rotating said brushes, means, 13, for supplying the material to said screen, refuse collecting and discharge means 13 for disposing of the material which is not forced through the screen by the brushes, a bowl or tank 14: surrounding the screen 10 to receive the material forced through the perforations of the screen and a supporting frame or base 15, on which the various parts are mounted.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Serial No. 156,489.

The screen 10 is closed at the bottom as indicated at 16 and is provided at its upper end with an annular frame 17 which rests on the ledge 18 of the annular channel member 19. This channel member 19 is provided with oppositely disposed trunnions 20 mounted in bearings 21 on the frame 15. I

Each of the brushes 11 is hingedly secured at to a brush ring 23. The nest of brushes rest freely and pivotally in the conical screen 10.

The means 12 for rotating the brush ring with the nest of brushes. comprises a spider Ql, the arms of which engage with hook shaped lugs 26 on the ring 23, a hollow shaft i i, to which the spider 2% is secured, a bevel gear 28 secured on the shaft 27. a bevel pinion Q9 meshing with the bevel gear 28, a shaft 30 on which the bevel pinion 29 is secured and a pair of fast-and

loose pulleys

31 and 32 mounted on the shaft 30. As shown in Fig. 1, the engagement between the arms and the lugs 26 is somewhat loose. This permits the ring 23, and hence the brushes 11 to act as floating members when the arms are rotated, to enable the brushes to adjust themselves to the screen 10, this adjustment being further facilitated by the pivotal connection at 22, which also acts to allow the brushes to float to adjust themselves to the screen. The shafts 2-7 and 30 are rotatably mounted in bearings 33, 34-, in the bearing bracket 36, which is pivotally mounted on the frame 15 by means of a shaft or pin 37. This pivotal mounting of the bracket 236 permits the shafts 27 and 30, with associated mechanism, to be swung up away from the nest of brushes and out of the conical. screen 10, to permit access to the brushes and screen for cleaning, etc.

Themeans 13 for supplying the material to the perforated screen, comprise in addi tion to the hollow shaft 27, a tubular connection 38, threaded into the gear casing 39 and communicating with the hollow shaft 27.

The refuse collecting and discharge means 1% comprise a refuse sweep l0 operating in the channel member 19 and secured to one of the brushes, and a discharge chute 4C1, lead ing from a suitable opening 42, formed in the side of the channel member 19. The channel member 19 may be provided with a suitable cover The bowl or tank 1 1 provided with oppositely located lugs H as follows: Power is applied to the fast pulley 31 by means of a dog causing the shaft 30 to rotate and with it the metal pinion 29. This causes the rotation .of the bevel gear 28, hollow shaft 27, and spider 25, the arms of the spider 25 engage the hook shaped lugs 26, causing the rotation of the brush ring and nest of brushes.

Material such as tomatoes, from the pulping machine is supplied to the screen 10, through the tubular connection 38 and hollow shaft 12. This material flows out between the brush and screen, and the brushes as they revolve, force the material through the perforations in the screen. The brushes are floatably mounted and bear on the pulp with a yielding pressure so as not to force substances such as mold and the undesirable parts of the tomatoes, such as the hard green portion, through the perforations in the screen. The finished material forcer through the perforations in the screen 10 escapes into the bowl or tank lei and is discharged through the opening The foreign substances and the harder portions of the tomatoes are gradually worked upwardly along the sides of the screen 10 due to the action of the brushes, and centrifugal force, and escapeinto the channel member 19. The refuse sweep 40 operating in the channel member 19 sweeps the refuse along the channel member and out through the opening 42 into the discharge chute 4E1.

In'working along the sides of the screen these foreign substances act somewhat as a pressure mat between the brush and the surface of the screen. In operation, the brush assumes a position such as shown in Fig. 4, the lower part of the brush being farther from the screen than is the upper part of the brush. The result of this operation is that no undesirable substances are forced through the screen and the finished product is of ood color and high quality.

Vhen it is desired to have access to the screen 10 or brushes 11, for cleaning purposes, etc, the spider 25 may be rotated slightly to free it from the hoolcshaped lugs 26, after which the bracket 36 can be swung about the pin 37 to lift the shaft 27 and spider 25 away from the brushes-l1. In doing this, it is, of course, necessary to disconnect the tubular connection 38. The nest ofbrushes can then be lifted out of the screen and if desired, the screen and the channel member 19 may be lifted out of the same to permitaccess to the bowl 14+.
