This invention relates to a comminutor or grinder for apples and like vegetables or fruit. In the production of cider from apples, it is current practice to reduce the j apples to small particles by cutting or gratmg them, and to express the juice fromthe comminuted apples by suitable means'such as a press. It has been common practice to per- I form the comminution by means of rotary 1O cutters or raspers housed within a drum. It

is desirable to have a compact cutter of great capacity, high speed and efliciency and the primaryobject of this invention is to pro vide a device attaining these objects. To a .16 this end, a more specific object of this invention isthe provision of a grinder having a vertical axis rotary cutter of drum type and including details of structure contributing to economy of operation and construction, simplicity and ease of manipulation.

These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawings in which:

. Fig. 1 is an elevation of a complete comminutor; Fig. 2 is a plan view thereof, the supporting frame being omitted Fig. 3 is a vertical section, showing the cutting drum in elevation; Fig. 4 is a section as seen on the line 4-4: of Fig. 3; Fig. 5 is an axial section through the cutter drum showing a fragment of the upper end; Fig. 6 isan elevation showing a fragment of a cutter drum of difl'erentconstruction; Fig. 7 is a section seen on theline 77 of Fig. 6 on an enlarg'ed scale; and Fig. 8 is an axial section through the structure shown in Fig. 6 showing the lower end of the drum.

. Referring with more particularity to Figs. 1 to 5 inclusive. a supporting framefor the mechanism is indicated by 10. Secured in a table or base 11 on the frame by any well known means and depending therefrom is the grinder proper. A. cylindrical neck 12 is provided with a flange 13 and pivotally secured tothe neck are clamps l l arranged to underhang the flange. The neck is provided with a throat 15 and a chamber at one side thereof constituting a drive gear housing in whichis mounted bevel gearing 16 whereby a drive shaft 17 operates a vertical shaft 18. The shaft 18 has radial thrust bearings atthe top and bottom and is arranged to carrya drum. Detachablysecuredto the neck 12 is a casing 19 of frusto-conical shape. At the larger end it is providedhvith aflange 20: corresponding to flange 13, so arranged that the clamps 1 1may be engagedtherewith to detachably hold the :case to the neck. :The. lower end thereof is formed with a bridge 21. having a hub provided with a bearing for the lower end of shaft 18. (There are ribs. or corrugations 23 on the inner. surface of the casing. Fixed to the shaft 18 is a drum having an imperforate cylindricalshell 24:.

At the end of the shell are arms25 meeting in a hub26 whichserves forsecuringthe drum to the shaft 18. Formed in the shell are parallel slots arranged at an angle to the shaft constituting flights of relatively great pitch. These slots receive tooth. bars "27 which arebevelled to an edge as shown in Fig. 4 there being several teeth formed therein along thelength of each bar. The bars are secured in position by a clamping cap 28 at the top and a clamping ring29 at the bottom, the cap being best shown in Fig. 5. Each of the tooth bars is provided at the ends with extensions 30, see Fig. 5, which are received in corresponding recesses in the clamping-cap and ring. 1 The latter are secured to the ends of the shell by means of screws. The construction is such that when the shaft 18 is rotated, the drum is rotated.

i In Fig. 1 a receiving memberBl is shown disposed upon the table 11. This is preferably a. revolving hopper adapted to hold apples which arefed to the mouth atthe throat 15 and thence into the case 19. The

details ofthe hopper are not shown as they are not pertinent to the present invention. Shaft 18 may be driven from an electric motor 32 or any other convenient source of power. it j The operation of the device is as "follows:

-Apples arefed from the hopper to the case and lodge inthespace between drum 24 and the wallof casing 19. Rotation of the drum tends to turn the apples, the corrugations 23 impeding such turning. The angular forabout said drum of the material being cut and mation of the bars tends to aid gravitative to guide the same from inlet to outlet.
