IMPRQVEMENAT meinen-MILLS.

Specification forming part of Letters Patent No.I 133,133, dated November 19, 187,2; reissue No. 5,890, dated May 26, 1874; reissue No. 5,982, dated July 21, 1874 application filed July l5, 1874.

To all whom -it may concern: y

Be it known that I, HENRY L. WHITMAN,

of St. Louis, in the county of St. Louis and letters of reference marked thereon.

Figure 1 is a side elevation, having a par of tooth-wheel broken away to show the movable bearing. elevation, showing the relative position of the rollers and casing. Fig. 3 is a plan of the machine, taken in the line ac x, Fig. 1. Fig. 4 is a side elevation of that portion of the casing which is provided with a slot for the reception of the movable bearings. It also exhibits the serrated face against which the bearing is secured.

Like letters of like kind refer to like parts.

This invention consists, mainly, in the peculiar construction of the crusher-roller, and in the construction and arrangement of the gears. It further consists7 also, in certain other details of construction, which will be fully described hereinafter. Y

In the drawing, Arepresents the hopper, of ordinary construction. B represents the casting, made of metal. 'This is provided with slots b b, of any desirable shape or form, for the' reception of the bearings, hereinafter described. C represents the crusher-roller, which is fastened to the shaft D. The crusher-roller is provided at the gear end with a conical depression, c, for the reception of the bearing E, which projects inwardly through the side of the casing. The object in projecting the bearing thus inwardly into the roller is to secure the. required length of the bearing without extending it beyond the out-side of the casing. The same result may be secured by extending the bearing outwardly and into a depression that the gear may be provided with, or the bearing may extend c into both roller and gear. The arrangement described Aenables the roller to extend nearly the width of the casing and the gear to be brought near the roller. The gear is fastened to the shaft D, which extends through the bearing E. To provide for the relative adjustment of vthe Fig. 2 is a central sectionall crusher-roller and that part of the casing termed the concave, the bearings E'E are provided with arms e c, preferably extended backward and downward, and provided near their lower ends with slots e1 el, for the purpose of attachment to the casing by any suitable means. The arms e e are further provided, at their lower end s and on their inner faces, with serrations e2 e2, which, when the arms are in position, engage in corresponding serrations on the sides of the casing, and enable the arms to be held more firmly in any desired position. As these serrations are not essential, they may be dispensed with, if preferred. The bearings E E are further provided with ilanges el e3, which, when the parts are in place, come between the end of the roller and the sides of the casing. These anges serve to keep the roller in place and to cover the slots. To adjust the roller to the concave, the bearings are moved in the slots b b to the point desired, and by tightening the thumb-screwf are held firmly. By using a detachable bearing in combination with a metallic casing it is easy to replace a bearing that is worn or broken without renewing the casing. The lower rollers I I are cast upon wrought-iron or steel shafts, H H, upon which are also cast gears Gr G. The roller and gears are placed any suitable distance apart, the only connection between them being the shaft.

By this construction and arrangement several advantages accrue: First, there being no fitting of wheel or roller to shaft, it is economical. Second, the wheel, the roller, and shaft forming one mass, any derangement in the relative position of vwheel and roller is prevented. It is desirable that the move ments of the wheels and the rollers should coincide exactly, as otherwise the lutings of the lower rollers, which are similar in size and shape, and which turn with equal velocity, would not accurately engage, and, in consequence, would be liable to breakage. Third, there being no cast metal connecting the roller and gear, the necessity for casting both simul! taneously is obviated. They can be cast successively, if preferred. Fourth, the spaces on the shafts between the rollers and gears can be utilized for journals, if desired.

By arranging the gearing outside the casing the pomace is kept out of the Way of the teeth, and by constructing the gear-wheels of equal size a uniform velocity is imparted to the rollers, and thereby better results are obtained.

Having described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a cider-mill, the Crusher-roller (l, having the depression e, substantially as described and shown.

2. The lower or grinding rollers, with gearing outside of casing cast upon their shafts, With space between roller and gear, connected only by shaft, substantially as .described and shown.

3. The combination of the crusher-roller,
