RAlSlN-SEEDER.

SPECIFICATION forming part of Letters Patent No. 551,967, dated December 24;, 1895.

Application filed April 30, 1895- Serial No. 547,615. '(No model.)

To all whom, it may concern:

Be it known that I, CHARLES M. HORTON, of Reading, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Raisin- Seeders, of which the following is a specification.

This invention relates to that class of raisinseeders employing a supporting-frame having a hopper, a serrated metal roll supported by the frame below the hopper, an elastic pressure-roll located at one side of the serrated roll, said rolls being arranged to receive between them raisins which fall from the hopper, and a comb-plate affixed to the frame below the serrated roll and having teeth which engage the serrations of said roll and eject therefrom the raisin-pulp which is forced into the spaces between the teeth of the roll bythe pressure of the elastic roll, the seeds of the ,raisins being pressed into the elastic roll by the serrated roll and carried downwardly and outwardly by the elastic roll until they drop upon a deflecting plate on the frame of the machine.

The invention has for its object to provide certain improvements in a raisin-seeder of this class looking to the convenient and ready separation of the serrated roll, comb-plate, and elastic roll from the frame of the machine, to the end that they may be conveniently cleaned; and to this end the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a raisin-seeder embodying my improvements. Fig. 2 represents a front elevation of the same. Fig. 3 represents a top view. Fig; 4 represents a section on line 4 4 of Fig. 1. Fig. 5 represents a perspective view of the comb-plate.

The same letters of reference indicate the same parts in all the figures.

The supporting frame of the machine comprises the arm or bracket a provided with suitable clamping means whereby it may be engaged with a table or other support, the hopper a formed on the upper portion of said arm, the chamber a below said hopper for the reception of the serrated roll I), said chamber being open at one end and at its bottom,

and a seat a formed on the lower edge of the side wall of said chamber to support the comb-plate c. The frame also includes the guides 00* a which project from one side of the hopper and are formed to supportthe block d, which supports the stud 01 upon which the elastic pressure-roll e is mounted to rotate loosely. The frame is also provided below the elastic roll with an inclined deflecting-plate a on which the raisin-stones which are carried away from'the serrated roll I) by the elastic roll drop, and by which said stones are deflected outwardly from the point where the raisin-pulp falls when dislodged from the serrated roll by the teeth of the comb-plate c.

The relative arrangement of the serrated and elastic rolls, the hopper, and the combplate, form no part of my present invention, said arrangement beingold.

frepresents a crank-shaft, which is journaled in a bearing a formed on the supporting-frame at one end of the chamber a shaft projects into the chamber a and is provided therein with a coupling member f, here shown as a pin driven transversely through the shaft and projecting outside the periphery thereon within the chamber (R. It will be observed that this pin by coming against the bearing a constitutes means for confining the shaft, and hence performs a double function.

The serrated roll e is provided with a lon- Said gitudinal bore formed to receive the shaft f and to move freely onto and off from the same, said roll being provided with a coupling member 6 formed to engage the coupling -member f of the shaft, said member 6 as here shown being agroove or cavity formed in one end of the roll e to engage the coupling member f, said members being formed so that the operation of placing the roll upon the shaft engages the two coupling members which rotatively connect the roll and shaft. The provision of the coupling members enables the roll to be secured in place upon the shaft by a simple device, such as a cotter-pin g engaged with the outer portion of the shaft and bearing on the outer end of the roll,sa id pin being readily removable so that the roll can be quickly removed from and applied to the machine.

The comb-seat a is parallel with the shaft Too I) and is provided with a clamping-screw a adapted to secure the comb-plate to said seat, said plate having an open-ended slot 0 extending lengthwise and formed so that when the screw a is loosened the comb-plate can be removed from the machine with the roll 1) without disengaging the teeth 0 of the combplate from the teeth of the roll I). It will be seen, therefore, that in order to prepare the serrated roll and the comb-plate for removal it is only necessary to remove the cotter-pin g and loosen, without removing, the clampingscrew a said roll and plate being then freely removable. After they are removed they can be conveniently separated and cleaned, and then re-engaged before they are reapplied to the machine,so that they can be applied simultaneously and secured by applying the cotterpin and tightening the clamping-screw (L The elastic pressure-roll e, which is made of rubber or a compound thereof, is mounted to rotate loosely upon the stud (1, which is screw-threaded and engaged with the block d, the latter being fitted to slide into and out of the seats formed upon the guides a a. The stud d is provided at one end with a clamping-nut (1 which bears against the outer sides of the guides a and co-operates with the block (1 in holding the stud in place on said guides when the device is in operation. By loosening the clamping-nut, the stud d, block (1, and roll 6 may be readily removed from the machine.

It will be seen that the described improvements make the separation of the parts for cleaning purposes very convenient, and their assemblage equally convenient, this being an important advantage when it is considered that the machine requires to be cleaned after every operation.

I claim In a raisin seeder, the combination of a supporting frame having a hopper and a journalbearing below the same; a crank-shaft extending through and beyond said bearing and having a radial abutment or abutments eX- tending over the end of the bearing and confining the shaft therein; a grooved and serrated wheel adapted to be slid onto said shaft andhaving a radial recess or recesses in one side receiving the abutment or abutments on the shaft whereby positive rotary connection is established between the shaft and wheel while their disconnection by longitudinal movement is permitted; means for confining the wheel on the shaft; and an elastic roll arranged in juxtaposition to the serrated wheel and adjustable toward and from. the same, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 27th day of April, A. D. 1895.

CHARLES M. HORTON. Witnesses:
