The present invention relates to crushing, grinding and refining machines, such as are used for crushing, grinding or refilling chocolate, paint, printers ink and other ma- .terials, and this invention is an improvement over the machine disclosed in my Patent No.

1,692,884,.granted November 27, 1928.

y One object of the invention is the provision of novel means for mounting and applying pressure to the grinding elements of the rotor or movable part of the machine.

Another object is to simplify the construction of the mounting and adjusting means for the grinding elements.

A further object is the provision of a novel grinding surface with which the grinding elements are cooperable for effectively crushing,.grinding, or refining the material.

With the' foregoing and other objects in view, which Will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made Within the scope of what is claimed, Without departing from the spirit of the invention.

The invention is illustrated in the accom panying drawings, wherein- Figure 1 is a vertical median .section of the improved machine, .portions being shown in elevation.

4o4 The casing comprises the cylindrical body 11 and end plates or heads 12 and 13. The end plate or head 12 has an inlet 14 near the top ofthe casingV Which is disposed with its axis horizontal, and said end plate has the hopper 15into which the material is dumped .each section of the rotor.

sets, contacting side by side. As shown,

there are three sets or groups of rods, one for The ends of the rods are Welded, as at 17, to the body l1, thereby holding said rods securely to the `1n` ner surface' of the body. The grinding surface of the body is thus conveniently pro-` duced by Welding the rods therein, and the grinding surface thus produced is effective.

or crushing, grinding or refining the material.

The end plate 13 has a normally closedy outlet 19 near the bottom of the casing, through Which the material may be discharged.

lThe end plate 12 has a bearing `20 through Whichsa tubular or sleeve shaft 21 is journaled, and a spindle y22 extends through the shaft l21.

A Wheel or s ider 23 is secured on the inner 4terminal o the shaft 21'within the casing and forms the body of the rotor.\ Slides 24 are movable radially in slots 26 in the ends of the arms of the spider 23, and thrust lwrods 27 are slidable radially in said arms and have their outer terminals seated in sockets 25 in the slides 24. The inner 4terminals of said rods are slidable Within a cage 28 fitted within the spider 23 and hav.- ing balls 29 therein against which the inner ends of said rods abut. Y

A cone or tapered cam 30 is secured to the inner end of the spindle 22 and is mov/- able between the balls 9, so that when the spindle is forced inwardly the cone being projected between the balls 29 will force said balls apart, thereby forcing the rods 27 outwardly. When the spindle is retracted the cone 30 is withdrawn, thereby permitting the balls 29 and rods 27 to move inwardly. A cap 30 is secured to the spider 23 for holding the cage 28. in place and to also enclose the balls 29 and cone 30.

The grinding elements shown in Figs. 1 and 2 are similar to those disclosed in Patent No. 1,692,884. Longitudinal rods 32 extend through the slides 24, and double leaf vmembers has two rods 38.

The pressure is distributed from lthe springs 33 to the rods 38, and the springs 33 may flex and also oscillate on the rods 32 to distribute the pressure between the two paiis of rods of each group. Therefore, when the spindle 22 is forced inwardly to force the rods 27 outwardly, the pressure is distributed uniformly from the slides 24 ,to the rods v38 by way of the rods 32,

springs 33 and members 36. The pressure is relieved when the spindle 22 is retracted.

The machine is driven by a gear wheel 44 Y secured on the shaft 21 at the outer side of the plate l2, and said plate` is formed with a housing 45 for said gear wheel having the removable cover 46 in whielrthe shaft 21 is journaled. Anti-friction thrust bearings 47 and 48 are provided to take up end thrusts of the shaft\ 21 in ppposite directions.

A tubular screw 48 is secured tothe housing cover 46, and a hand wheel 50 has a bushing 51 threaded on said screw, for moving the hand wheel axially -when it is rotated. An annular plate 52 is secured to the hub of the hand wheel and is disposed lietween a pair of anti-friction thrustv bearings 53l secured on the outer terminal of the spindle 22 by means of the nut or retaining element 54, whereby the spindle 22 is moved inwardly and outwardly by rotating the hand wheel which travels inwardly and outwardly by screwv action. The swivel conne'ction between the'spindle and hand wheel Vpermits the spindle `to rotate with the Y shaft 21.

-A cap 55 is secured to the hand wheel 50 with the plate 52 to house and protect the bearings 53 and outer terminal of the spin,- dle. v

The spindle 22 may be adjusted duringthe operation of the machine by merely rotating the hand wheel 50, so that the. pressure on the grinding rods 38 may bc regulated.

The rods .38 being moved across the fixed rods 18 will provide an effective grinding action. As shown, the rods l38 are of larger diameter than the rods 18.

Figs. 3 and 4 illustrate a modification. An elongated slide 24EL is'slidably mounted between its ends in the slot 26a of each arm of the spider 23, and rods 33a pass slidably through said slide 24 and are suitably connected at their ends, as at 3521, with the members 36a to which the grinding rods 38a are secured. The thrust rod 27a has a terminal of reduced diameter entering the socket 25a in the slide 24a, and a bowed leaf spring has its terminals bearing 'against the inner surface offthe slide 24 and its intermediate portion has an aperture through which the reduced terminal of the rod 27a extends, a collar 61. being "disposed on said terminal between the shoulder of the rod and the spring 60, so that when the rod is forcedoutwardly it applies a straightening-out pressure to the spring 60, andthe terminals of the spring press against the slide 24a, thereby applying the pressure to the rods 33, members 36a and rods 38a.

The rods 33a are slidable loosely in the slide 24, and the members 36a in front of 'y the slide 24a contact at their rear ends with said slide, to move the members 36a and rods 38a with the slide 24L when the rotor is rotated, the rear members 36a being pulled with the rods 33a.

Both constructions are such that when the rods 27 and 27n are retracted they will release the

slides

24 and 24a, respectively, to permit them being removedfrom the spiders, thereby enabling the groups of grinding elements to be readily removed for repair or replacement. i

As shown in Figs. 5 and 6, the springs 33b extend 'across bars 32b and are clamped between said bars and clamp plates 341. The intermediate portions of the bars 32h are slidable in the slots 26b of the spider 23b and have plates or blocks 24h secured thereto and sliding in said slots. Said blocks have sockets 25b receiving the outer ends of the rods 27" and lcontaining wear pieces 25. against which the rods abut. i i

The other parts 2lb, 22h; 28h, 291?, 30h, 35", 30h and 38b are substantially the same as the corresponding parts in the constructions hereinbefore described.

1. In a grinding machine, a body. and rods disposed sideby side and having their ends welded to said body to rovide a ribbed grinding surface, said rods eing disconnected between their ends from said body.
