CHILIAN MILL.

Specication of Letters Patent.

Patente-d Nov. 7, 1911.

Application filed January 13, 1911. Serial No. 602,379.

To all whom it may concern.'

Beit known that I, ALEXANDER J. MCCONE, a citizen of the United States, residing at Reno, in the county of Washoe and State of Nevada, have invented certain new and useful Improvements in Chilian Mills, of Which the following is a specification.

My invention relates to the class of Chilian-mills.

The object of my invention is to provide, by simple and eifective connections, for the necessary vertical movement of the crushing i'ollers under Working conditions, independently of the driver and of each other; and also to provide, by a simple and effective construction of the rollers themselves, for increased crushing Weight Without an increase of bulk.

To these ends my invention consists in the novel construction and arrangement of parts which l shall hereinafter describe and claim, reference being had to the accompanying drawings, in Which Y Figure 1 is a vertical section of my mill. Fig. 2 is a plan of the same, partly broken, and the feed trough and driving gears omitted. F ig. 3 is a side vievv enlarged of the mounting connections for each roller, the yoke being in section. Fig. 4 is a top view of the roller axle and yoke.

1 is the mill bottom With a central column 2 in which is keyed the non-rotating shaft 3.

4 is the center cone, with face liner 5.

6 is the die, 7 the screens and 8 the launder.

9 is the driver mounted to ro-t-ate about the shaft 3, and driven from above through the gear 10.

11, in Fig. 1, is the feed trough and 12 are the feed pipes.

14 are the crushing rollers. I have shovvn three in the present case. Each roller has a tire 15 to run on the die 6. The means for mounting each roller being the same, a description of one Will apply to all.

The driver 9 has made in the extremity of each of its arms a rectangular hole in which is fitted the upper end 16 of a correspondingly shaped post'lt. This upper end 16 is of smaller cross section on one side than the post itself thus forming a shoulder at 17 which bears under the outer end of the driver arm. The end of the driver arm, which forms the outer Wall of the postreceiving hole is split through to said hole as shoivn vin Fig. 2 at 18; and bolts 19 are passed horizontally thro-ugh this end and lie in seats formed in said end and the adjacent Wall of the post. By tightening up these bolts the post is clamped securely in the arm. The bolts by seating partly in the arm and partly in the post also resist endvvise move- .ment of the post, but the upward thrust which is likely to be the most severe is effectually resisted by the shoulder 1 7. Thus the post is Well and rigidly secured and will resist any strain put upon it, more certainly than if it were merely bolted to the arm.

2O is the roller spindleor axle, the outer end of which receives a nut 21 which is covered by an oil guard 22. The inner end ofthe spindle or axle 20 is formed or provided With a yoke 23 angularly shaped to embrace with a sliding fit three sides of the driver post 16. The extremities of the yoke are fitted with rolls 24 which lie upon the back or fourth side of the post. In order to better resist any canting strain, th-e yoke arms Widen to their extremities and carry three rolls 24, as seen in Fig. 3. The effect of these connections is 4that each crushing roller 14 can have its verticalA movement under Working conditions independently of the other rollers, and also independently of the driver, so that the strains and stresses of one are not communicated to another, as in those cases in Which the driver itself is intended to form part of the crushing Weight. Each roller `rises vertically parallel to its post, Without tilting strain, its yoke sliding true upon the post, thereby maintaining the proper relative position of its tire and the die. The construction is much simplified by having the yoke slide directly on the driverpost, and by this reduction in the number of parts forming the mounting connection, a certain amount of Weight is dispensed Wit-h Which Would cause Wear in the journal. Also, as before noted, the post itself is firmly secured to resist strains. The crushing rollers 14 are formed in tvvo sections meeting in their circumference, as seen in Fig. 1, one sect-ion having the hub over which the other fits; and the periphery of these sections are oppositely beveled to -their meeting line as shown. This provides for securing the tire 15, the inner surface of Which is complementally beveled, When the sections are clamped together, and thus avoids the use of independent Wedges. The sections of the rollers are hollovved out as shown and in the chamber thus formed is inserted a mass 25, as shown in Fig. l, of lead or other relatively heavier metal, whereby the weight oi' the roller is increased without affecting its bulk. The sect-ions or" the roller and the inserted mass or iilling 25 are securely clamped together by means of sleeves 2G secured by screws 27 to one section and receiving tapbolts QS from the other section. This provides convenient means for separating the roller sections to insert the filling and to clamp them together again to hold the tire.

`l-laving thus described my invention .what I claim as new and desire to secure by Letters Patent isl. ln a Chilian-mill, the combination of a driver, posts of rectangular cross section secured at their upper ends to the drivei, crushing rollers, and a connection between each roller and its post consisting of an axle on which the roller is mounted, said axle having at its inner end a rectangular yoke which embraces the three sides of the post with a sliding tit, and rolls carried by the yoke arms and bearing upon the fourth side ot the post.

2. In a Chilian-mill, the combination of a driver having an arm with a rectangular hole from which the arm is split outwardly to its extremity, a post of rectangular cross section litted at. its upper end in the hole in the driver arm, said post having near its upper end a shoulder which bears against the underside of the arm, clamping bolts passing across the split extremity of the driver arm and engaging also the wall of the post, a crushing roll, and a connection between said crushing roll and the post.

3. In a Chilian-mill, the combination of a driver having an arm with a rectangular hole from which the arm is split outwardly to its extremity, a post of rectangular cross section fitted at its upper end in the hole in the driver arm, said post having near its upper end a shoulder which bears against the underside of the arm, clamping bolts passing across the split extremity of the driver arm and engaging also the wall of the post, a crushing roll, and a connection between said crushing roll and the post consisting of an axle on which the roller is mounted, said axle having at its inner end a rectangular yoke which embraces the three sides of the post with a sliding tit, and rolls carried by the yoke arm and bearing noon the fourth side of the post.

ln testimony whereof I have sign-ed my naine to this specification in the presence ot two subscribing witnesses.
