COFFEE-MILL.

SPECIFICATION forming part of Letters Patent No. 576,160, dated February 2, 1897.

I Application filed June 16, 1896. Serial No. 595,774. (No model.

To all whom it may cancer/1 Be it known that I, HUGH G. SAMMONS, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Coffee-Mills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon, in which Figure 1 is a perspective view showing parts broken away and the cover or lid removed. Fig. 2 is a vertical section. Fig. 3 is a view showing a portion of the crank. Fig. 4.- is adetached view of the hopper, grindingshell, and the grinding-disk. Fig. 5 is a detached view of the grinding-disk support,

showing the location of the ball-bearin gs.

The present invention has relation to coffee-mills; and it consists inthe different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar letters of reference indicate correings.

In the accompanying drawings, A represents the box or casing, which may be constructed in the ordinary manner, reference being had to properly attaching the different parts belonging to the mill proper.

To the box or casing A is detachably connected the drawer B, said drawer being constructed in the ordinar anner.

I To the box or casing A. are connected the bars a, which bars are located a short distance below the top of the casing, as illustrated in Figs. 1 and 2. The bars a are for the-purpose of supporting the base 0, said base being substantially of the form shown in Fig. 5, and, as shown, it is provided with the openings 1), which openings are for the purpose of allowing the ground coffee to fall into the drawer B. The base 0 is provided with the annular groove cl, which annular groove receives and holds the antifriction-balls 01, said antifriction-balls being arranged as illustrated in Fig. 5.

The grinding-disk D is formed in the shape of a cone, and is provided with the ordinary central opening having a milled face corresponding substantially with the milled face of the grinding-disk, said grinding-shell being held in proper position by means of the clamp bolts g, which clamp-bolts pass through the base 0 and the bars Ct, as illustrated in Fig. 2. The bottom or lower ends of the bolts g are provided with the nuts 9, said nuts being for the purpose of holding the grinding-shell E against upward movement, and at the same time providing a means for adjusting the grinding-shell E, or, in other words, allow said grinding-shell to move away from the grinding-disk when the nuts g, are loosened or turned downward upon the bolts g.

The grinding-disk D is provided with the shank F, the top or upper end of which is angular to receive the angular aperture h, formed in the crank it. For the purpose of holding the grinding-disk, together with its shank, in proper position the yoke G is provided, which yoke is securely attached to the grinding-shell E in any convenient and wellknown-manner; or, if desired, the yoke may be formed integral with the grinding-shell.

It will be understood that by providing the grooves cl and e and placing the antifrictionballs d in the position illustrated in the drawings the grinding-disk will be easily rotated and at the same time will be held against lateral displacement, thereby providing a coffee-mill that will be easy in operation and at the same time well calculated for the purpose designed.

Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-= The combination of a box or casing provided with a drawer, the bars a, secured to the casing, the base 0, provided with openings and the annular groove (Z, the grindingdisk D, provided with the annular groove (2, hereunto subscribed my name in the presence the antifrietion-balls 01 located in the grooves, of two Witnesses. the shoulders f, the grinding-shell E, and the t HUGH G SAMMONS clamp-bolts g, passed through the base 0, 5 and the bars a, substantially as and for the purpose specified.

Vitnesses:

F. W. BOND,

In testimony that I claim the above I have J. A. J EFFERS.
