JOHN M. LENZ AND TIMOTHY E. REGAN, OF GRAND ISLAND, NEBRASKA.
SHARPENER.
Application filed. June 6, 1916.
To all whom it may concern:
Be it known that we, J HN M. LENZ and TIMOTHY E. REGAN, citizens of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented new and useful Improvements 1n Sharpeners, of which the followlng 1s a specification.
The invention relates to an improved sharpener, designed to be constructed as an entirety and adapted primarily for application to a sewing-machine, or like devlce.
The sharpener embodies a member having means to permit it to be adjustably connected to a fixed shaft of the sewmg machine, in such position that a drlvmg shaft, carried by the device, may be operated by a belt connection or frictional contact wlth a rotating element or wheel of the machine, the driving shaft carrying a sharpening or polishing disk or wheel.
The invention in the preferred form of details, will be described in the following specification, reference being had partlcularly to the accompanying drawmgs, 1n which:
Figure 1 is a front elevation, illustrating the applicaion of the improvement to a sewing-machine; Fig. 2 is a perspectlve new of the improvement. Fig. 3 is a broken vertical section through the frame bar, illustrating the clamping means.
In detail structure, as will be plain from the accompanying drawings, the improved attachment includes a frame bar 1, transversely in which is mounted in an appropriate manner, a driving shaft 2. On one end of this shaft is removably mounted a sharpening or polishing disk or Wheel 3, and on the opposite end a friction pulley l.
At one end of the frame bar is provided a means for clamping the device in place, and the opposite end of the bar is covered to the desired extent by a protecting strip 5, which will permit the said end of the bar to rest upon the machine top or table without 1njury to the latter.
At the clamping end of the bar, the latter is formed with a channel 6, extending longltudinally thereof and opening through the end of the-bar. The channel does not ex tend entirely through the bar, but a slot 7 is formed in the base of the channel to extend through the bar, the slot 7 being of less 1 length and width, than the similar dimensions of the channel.
Specification of Letters Patent.
Patented Aug. as, m1 6.
Serial no. 101,992.
Theclamping means includes a block 8 slidably mounted in the channel, and having a rod 9 threaded therethrough. The ends of the rod on respective sides of the block are reversely threaded as at 10, and 11, and mounted on these threaded portions are clamping jaws 12, and 13, which by turning the rod, may be adjusted toward and from each other in an obvious manner. The rod may be provided with a head or fixed nut 14, by which it may be operated to adjust the jaws. The block 8 is threaded to receive the shank of a thumb screw 15, the said shank passing through the slot 7, and there being provided with a washer 16, between the head of the thumb screw and the adjacent surface of the frame bar. Through the obvious use of the thumb screw the blocks may be locked in any desired position longitudinally of the channels within limits of the slot.
In application, the device is applied to the shaft of the balance wheel of a sewing machine or the like, through the clamp described, the adjustment of the clamp longitudinally of the bar being such that when in this position the grooved pulley 4 will frictionally bear upon the periphery of said balance Wheel, so that the shaft 2 is operated by said wheel. By this means, the polishing or grinding disk 3 is driven to permit polishing, grinding or other treatment of any edge tools or other devices.
While the device is designed for application with any and all types of sewing machines, it is adapted particularly for that class of machines in which through the adjustment of a nut the balance Wheel and its driving element may be free from the operating shaft of the sewing machine mechanism, in order for example that the bobbin winding wheel or the like may be operated for winding the bobbin without actuating the needle bar, etc., of the sewing mechanism, Following the loosening of this clamp nut to free the balance wheel the clamp of the improved sharpener is applied to such clamp nut.
Having described our invention, what we desire to secure by Letters Patent is 1. A sharpener structure designed to be applied to a sewing machine, including a frame bar, a clamp carried thereby to em gage a shaft of the machine, a driving sho ft carried by the frame bar, a pulley carried by the shaft to frictionally engage the 1'0- tating part of the machine, and a grinding the shaft, and an operating disk carried by disk secured on the shaft. the shaft. 2. A device of the class described, inciud- In testimony whereof we aflix our signa- 10 7 ing a frame bar, a clamp adj ustably mounted tures.
5 in one end of the frame bar, an operating shaft mounted in the frame bar, beyond the JOHN M. LENZ. clamp, a friction driving means carried by TIMOTHY E. REGAN.
