FINISHING MACHINE.

Application filed February 14, 1924. Serial No. 692,716.

1 0 all whom it may concern:

Be it known that we, AUGUST Homuoorsr and WILLIAM A. BJoRKLUNn, citizens of the United States, residing atHoopeston, in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Finishing Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to improvements in finishing machines and more particularly to machines for preparing the pulp of the to-.

mato, by reducing it to the proper consistency, in the manufacture of ketchup.

While I shall describe my invention in connection with a machine particularly designed to handle tomato pulp for the pur pose described, it will nevertheless be understood that the invention is capable of embodiment in whole or in part,'in similar and non-analogous arts, and need not be limited to this use solely.

The finishing machine disclosed herein is an improvement over the machines disclosed in United States Patent 1,393,9 l9, granted to Harry W. Lowe on October 18, 1921, and in United States Patent l,454e,031,granted to Leland A. Babcock on May 8, 1923, both of which and the present invention have been assigned to the same assignee.

In these prior patents, the machines disclosed are each provided with a revolving brush operating in close proximity to a finely perforatedscreen or sieve. 'The pulp is fed so that it will pass between the brush and sieve. The finer portion of the pulp immediately passes through the sieve, while the heavier material containing crushed seeds, pieces of skins, etc., is picked up by the revolving brush and gradually worked up the sides of this sieve where it is discharged from the machine.

The object of the present invention is to provide an improved mounting "for the brushes, driving mechanism and the sieve, whereby more convenient access may be obtained to the brushes and screen for cleaning or repairing, and a more rigid mounting obtained for the driving mechanism.

In Patent No. 1,454,031, the machine may be opened trom the top by means of a pivotally mounted bracket. Upon this bracket, the driving mechanism is positioned. When ever the brushes or sieve require inspection or cleaning, the driving belt must be disconnected. Furthermore, difiicultyis encountered in preventing undesirable vibration of this bracket. According to the teachings of the present invention, the bowl which carries the sieve is pivotally connected and is adapted to swing downwardly when released so that this brush will be exposed for cleaning or repairing from the under side. The 'brush remains in its operative position during this time. It is, therefore, not necessary to disturb the clearance betweenthe brush andscreen. A marked advantage is thereby obtained in that the finished product of the machine remains uniform. This would not always be obtained where the brush had to be adjusted each time. However, I make'provisionherein for adjusting the brush in cases where necessary, as for instance, when new brushes are inserted.

The novel construction disclosed herein further permits a quick removal of the screen. The screen is likewise novelly constructed, being provided in sections and reinforced, preferably where the sections are joined. Consequently, should but a portion of the screen wear, it will not be necessary to replace the entire screen as was heretofore required. A considerable saving is thereby aflected.

I wish to point out that by opening the machine at the bottom, it is possible to clean the brushes with greater facility than when the machine is opened at the top); With the bottom open, the entireinterior may be readily flushed with clean water, the brushes being positioned so that their outer surface may be washed in a direction away from the machine.

Other advantages and objects will appear from the following detail description taken in connection with the accompanying drawings, in which: i

The preferred form of construction illustrated in the drawin scomprises legs 10 upon which is supported a hopper frame 11, a revolving brush. 12-mounted upon and driven by a center tubular shaft 13, a novel screen construction 14 and a pivotally mounted hopper 15.

The legs 10 may be of any suitable design, but as I have shownthem, they consist of a pair of side frame-members 16 and 1'? connected together by stay rods 18. Uponv the upper surface ofside frame- members 16 and 17, the hopper: frame 11 is suitably bolted at the various points designated 18. As will be.- seen in Fig. 2, this hopper frame 11 is provided with a transverse bracket 19, which bracket. 19 is adapted tohave a driring bracket 20 'boltedthereon. The outer end of the drive bracket 20 is bifurcated to provide. bearings 21 for a' drive shaft 22. This drive shaft 22; extends beyond each. bearing 21 for receivingpulleys 23. A belt 24' is entrained over these pulleys 28 and a drive pulley 24 splined to the central tubular shaft 13.

At-a lower point; on this tubular shaft a pair of spaced annular brush driving members 25' and 26 is fixed thereto, and upon these driving members a series of elongated brushes 2.7 are supported, which brushes are syn metricallyarranged about said shaft for operation with the conical screen 14 arranged within the bowl 15. As will be seen in Fig. 2.

a clearanceis provided between the screen 14 and the brushes 2.7, so that, during the revolving of the brushes, the pulp will not be forced through the screen, but on the other hand, the pulp will be allowed to travel gently overthe inner surface thereof to permit the pulpy liquid to run through the perforations and the heavier material containing crushed seeds, pieces of1skin, etc.. to. pass upwardly to an annular channel .l. refuse sweep 30 is fixed to one of tle brushes 2? and is adapted to move through the annular channel 28 and carry this heavier material of the pulp to the discharge spout 31.

An adjusting wheel 32 is suitably threaded to a sleeve 33 concentrically mounted with respect to the center shaft 13. This adjusting wheel 32 is adapted to raise and lower the two brush driving members 25 and 26, and consequently raise and lower the brushes 27 with respect to the conical screen 14. I have found it advantageous to i provide supporting rods 34 between these convenient access to the brushes may be obtained for the purposes of cleaning and repairing the same. The open position of the bowl 15 is shown in Fig. l. I

By referring to Figs. 4 to 9 inclusive, it will be noted that the screen comprises four sections 40, 41, 42 and 43. As is illustrated in detail in Fig. 7, the adjacent edges of, say, sections 41 and 42 are overlapped into an interlocking fold, with a channel member 44 for embracing the folded portions and securing the same together. The channel members 44 are preferably made of a metal which allows the same to be pressed about the fold and to be held in thisposition without additional securing means. e, however, could employ bolts, or the like, for locking the channel in place, but, with the present arrangement the use of bolts is unnecessary.

By referring to Fig. 8, it will. be noted that the upper circumferential edge of screen 14 is held clamped between an upper ring 45 and a lower ring 46, these rings being suitably secured'together, say, by bolts 47. A similar arrangement is provided for the lower edge of the screen 14. As shown in Fig. 9, a casting 48 comprises the bottom of the screen 14, and about this casting 48 an annular retaining ring 49 is bolted b means of bolts 50. This retaining ring 49 clamps the loweredge of the various screen sections against an inclined face 51 formed on the casting 48. Been-forcing rods 52 are employed between the upper and lower edges of the screen 1.4 to hold the latter rigidly extended. These rods at their upper end thread into suitable bracket members 53 bolted at 54 to the lower clamping membra- 46. At the lower end the reenforcing rods 52 pass through apertured lugs 56 on the Cir closed position.

annular retaining ring 49. Nuts 57, or other suitable means, may be used for holding these lower ends in the lugs 56.

The material to be treated, such as tomato pulp, is introduced into the machine by depositing the same into a hopper 58, support ed .by bracket 20, said hopper being arranged to discharge into the upper end of thehollow shaft 13, whence the material travels'downwardly in said shaft andv is deposited into the lower end of screen 1e. At this point, the material is caught up by the brushes 27 and forced thereby through the screen 14. Refuse, such as the heavier portions of tomatoes, is forced by said brushes into the annular passage 28. The refuse collected in said passage is carried by refuse sweep 30 to the discharge opening and passed therefrom through the discharge chute 31 which leads laterally from the machine. The material which, is forced through the screen enters the passage or space 59, whence the same passes downwardly and is discharged through the outlet 60.

It will be noted that the screen 1 1 is seated within the bowl 15, so that the former may be removed from the underside of the machine, for repairing or cleaning, when the bowl is pivotally swung to its open position, as shown in Fig. l. The brushes 27 are normally secured to the shaft 13, through the driving members 25 and 26, whereby these parts may assume a unitary relation in that they remain secured to each other and permanently positioned within the frame of the machine, and are not disturbed upon cleaning of the brushes or the screen. In View of this relation, it is preferable to prohibit the upward movement of the screen 141-, so that when the bowl 15 is locked in closed position, the screen will also be locked in a rigid position upon the machine, to prevent variance in the clearance between the same and the brushes 27, and furthermore because the invention is directed to a rigid. mounting for the driving mechanism, in order to eliminate undue vibration, and also to secure a more efficient driving arrange ment. As before explained, the upper annular clamping members 15 and 46 of the screen is seated in a recess 35 formed in the annular member 36 of the bowl. To prevent this upward movement, a flange 64 is formed -upon the interior of thehopper frame 11 and extends a distance suflicient to engage the screen 14. This flange cooperates with the annular member 35 to form a recess closed on three sides when the bowl is in Thus the screen 14 is se curely held in position on the machine.

As. shown in Figs. 1 and 2, I have provided a pair of cam locking members 61, which are pivotally mounted and adapted to engage the member 36 to hold the bowl locked in closed position. These cam locks 61 are mounted to operate in a horizontal plane, and are provided with a cam edge 62, which engages a downwardly slanting beveled side 63 on member 36.

From the foregoing it will be seen that I have provided a novellyconstructed finishing machine that may be used for reducing tomato pulp to a proper consistency, in the manufacture of ketchup, it being possible however to use other material when the machine can aptly be used therefor and will admit of such use. The pulp feeding mechanism and driving mechanism for the revolving brushes are uniquely combined, and, with the brushes, these parts are arranged so that they may have a substantially rigid mounting. The bowl and screen may be removed without interfering with this mounting, and consequently access to those parts requiring cleaning or repairing may be obtained in a very convenient manner.

Without further elaboration, the foregoing will so fully explain the gist of my invention, that others may, by applying current knowledge, readily adapt the same for use under varying conditions of service, without eliminating certain features which may be properly said to constitute the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.
