MOTOR MECHANISM FOR MILLS.

SPECIFICATION forming part of Letters Patent No. 654,083, dated July 17, 1900-.

Application filed November 1, 1899. Serial No. 735,502. (No model.)

T0 at whom, it may concern:

Be it known that I, CHARLES JOSEPH Wns- TON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Motor Mechanism for Mills and I do declare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to motor mechanism for grinding, chopping, and churning mills, and more particularly to means for accelerating the speed of such machines, thereby reducing the time and labor required to grind, chop, or churn the material.

The object of the invention is to provide a device of this character which shall be simple of construction, durable in use, and comparatively inexpensive of production and which may be easily applied to machines of this description.

with this object in view the invention consists in certain features of construction and combination of part, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure l is perspective View of a coffee-mill, illustrating the application of my invention. Fig. 2 is a perspective view of my device applied to the wheel of the mill; and Fig. 3 is a View, on an enlarged scale, taken centrally through the hub of the mill.

In the drawings, 1 denotes the mill, which may be of any well-known or approved construction, provided with the fiy-wheels 2.

3 denotes a clamp, preferably consisting of the ring 4 and a disk 5, which are secured together by bolts 6, that extend between the spokes of the wheel. The face of this disk 5 is provided with a hub 7, formed with a reduced annular shoulder 8, integralwith which are a pinion 9 and a stud-bearing 10.

11 denotes the frame, preferably U-shaped and provided at its upper end with an enlarged bearing-aperture to engage the annular shoulder 8 and with a small bearing-aperture to engage the stud-bearing 10. A setscrew and a washer are secured to the end of the stud-bearing and serve to prevent the lateral displacement of the frame.

13 denotes a gear-wheel, the axis 14 of which is journaled in the frame and is provided with a head 15, formed with an aperture 16 to re ceive a crank 18, which is adj ustably secured therein by a set-screw 19.

20 denotes a chain which connects the frame to the floor and serves to prevent the rotation of the frame as the mill-wheels are revolving. Any other means may be em ployed in lieu of a chain for preventing the rotation of the frame. It is evident that by gearing the pinion with the large gear upon the rotation of the crank an accelerated speed will be imparted to the machine, thus saving much time and labor in the act of grinding coffee.

If it be desired to adjust the sweep of the crank, this may be easily accomplished by loosening the set-screw and moving the crank eitherin or out, as the case may be.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the device will be readily apparent without requiring an extended explanation.

It is evident that the device may be at tached to any of themills now in use and for this reason may be placed upon the market as an article of manufacture and sold separately and applied to the mills by purchasers themselves. It will also be understood that various changes in the form, proportion, and the minor details of constraction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

The combination with the fly-wheel of a coffee-mill, of a clamp secured thereto and consisting of a ring and a disk bolted together, the disk being formed with an annular shoulder and with apinion and a studbearing, a frame having bearing-apertures to engage the annular shoulder and the studbearing, a gear-wheel j ournaled in said frame, and a crank for rotating the gear-wheel, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. I

CHARLES JOSEPH WESTON. Witnesses:

J. BARTON LARGE, MAHLON CALLAHAN.
