COFFEE-MILL.

SPBCIEICAEION forming part of Letters Patent No. 333,870, dated January 5. J 886.

Application filed April 16, 1885.

T0 aZZ whom z't may concern:

Be it known that I, MATTHEW LEPAGE, acitizen of theUnited States, residing in Woodbaven, in the county of Queens and State of New York, have invented certain new and useful Improvements in Coffee-Mills, of which the following is a specification.

The invention relates particularly to the class of cofiee-mills employed for domestic purposes.

The object of the invention is to simplify the construction, thereby lessening the expense of the mill, and at the same time rendering it more durable.

The invention consists in providing simple and efficient means for supporting the upper or outer grinding-surface and the lower end of the shaft of the inner or lower grinder. A brace or strap is secured to the wall of the hopper, instead of to a separate supportingplate, as bas heretofore been the custom. This enters the hopper, and is secured to its inner wall. It is provided with shoulders for supporting the stationary or upper hopper, and it enters suitable recesses formed in the edge of the same, thereby preventing it from tuming. The ends of this strap extend inside the hopper, and are secured to the inner surface. This construction secures a more firm and rigid support than can be obtained by fastening the brace to the outside, for the downward pressure exerted thereon is resisted by the broad bearing-suriace of the brace upon the hopper.

No claim is herein made upon the means for attaching the handle, nor for adjusting the position of the grinders, as these features are In the accompanying drawings, Figure 1 is a vertical section of the mill, showing in full the adjusting device. Fig. 2 is a plan view of the stationary grinder and strap.

Beferring to the figures, A represents the supporting and inclosing box of the mill, and B the hopper. The outer grinding surface, 1), is placed at the base of the hopper, and is supported in its proper position by means of a strap or brace, C. The ends of the strap extend within the lower end of the hopper, and are turned outward, so as to bear against Serial No. 162,452. (No model.)

its inner surface. They may be riveted to the metal of the hopper or fastened in any other convenient manner. They are preferably let into corresponding recesses, ce, formed in the lower edge or fiange ofthe hopper. The 1ower end of the cylindrical grinder b rests against suitable shoulders, e, formed upon the vertical portions of the strap C, and the upper edges of the same have recesses f just beneath the recesses c, into which the corresponding portions of the strap or brace fit tightly. These prevent the stationary grinder from turning in its support. In this manner the outer grinding surface or cylinder is securely held in position. The middle portion of the strap is horizontal, and at its central point there is formed au opening, g, designed to receive the lower endoftheshaft G,carryingthegrinderG, which is fitted withinthe outer grinder above the strap C. The lower end of the shaft G extends loosely through the opening 9, which serves to retain it in position. The upper end of the shaft carries a nut, H, turniug upon a screw-thread. A sleeve, J, encircles the shaft below the nut, and the lower end of the sleeve rests upon a collar, K,whioh is supported from the upper portion of the hopper. The sleeve J carries two upright projections or lugs, one

of which is shown atj, and the nut rests upon the ends of these projections. VVhen the nut is sorewed upon the shaft, itis evident the 1atter will be raised,-thu lessening the distance between the griuding-surfaces, and by loosening the nut the space between the grinders Will be increased. The handle M is secured rigidly to the shaft by arivet passing through the hub m, or in any other convenient mauner, and, when turned, carries With it not only the shaft and adj usting-screw, but also the slceve J.

It should be notioed that the length of the 9c lugsj and j is such that the handle may be moved vertically with reference to the same a sufficient distance to permit of the required adj nstment of the grinder.

I claim as my invention- 1. The combination, substantially as hercinbefore set forth, With the hopper of a cofieemilland its stationary grinder, of a support ary grinder, the ends of said strap beng secured in recesses within the hopper, substantia1ly as described.

In testimony whereof I have hereunto subscribed my name this 14th day of April, A. 15

MATTHEW LEPAGE.
