Specification of Letters Patent.
Patented Sept. 18, 1906.
Application filed July 31, 1905. Serial No. 272,090.
To all whom, it may concern."
Be it known that LJOHN W. OHALLONER,
a citizen of the United States, residing at. the city of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in F riction- Clutches, .of which the following is a specifica- 'tion.
This invention relates to improvements in friction-clutches, and particularly to a friction-clutch adapted to the operation of a sawmill-carriage, shingle-machine carriage, and the like, or any device requiring reclprocal movement.
shoe.
The object of the invention is the provision of means for facilitating the operation of a clutch requiring reciprocal movement.
With this and other objects in view the in-.
vention consists of certain other novel. constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

a perspective view of the box, shoe, and cooperating parts for actuating said shoe. Fig.
5 is a Vertical longitudinal sectional View of the box of the shoe, showing the crank-arm and a portion of the rocker-arm in side elevation. Fig. 6 is ,a perspective view of the Fig. 7' a perspective view of the crank-arm. V I
Referringfto the drawings, 2 designates a machine-frame, and 3 the carriage. The carriage 3 slides on usual ways or tracks 4 of the machineframe 2.. Power is applied to the pulley 5, which. drives the pulley 6 upon the same shaft: An endless belt 7 is mounted up on and isdriven by the pulley 6 beneath the roller 8 and around the idler-pulley 9. The
tension of thebelt is regulated by means of, the bolt .10, set in the sliding pulley-frame 12 and passing through an eye in the lug 13. The bolt 10 carries a nut 11. By adjusting the nut the tension of the belt is regulated.
A box 14 is fixedly secured to the carriage 3, and within said box a shoe 15 is positioned.
The box is open at both ends and the belt 7 passes through the box above and below said shoe 15, Figs. 1, 3, and 4. The shoe 15 is operated upwardly or downwardly against the belt 7 by means hereinafter described. The shoe when sufficiently so operated presses the belt either against the top or bottom of the box, thereby applying the friction to both the outer and inner surfaces of the belt. It will be understood that the top portion of the belt is always traveling oppositely to the bottom portion. Therefore reciprocation of the carriage is effected whenever the pressure of i the shoe is changed.
The shoe 15 and the box 14 are preferably of the same shape, which is in the present instance rectangular. The shoe 15 is operated by the lever 16, pivoted to the carriage 3 at 17 ,and connected by means of a link 18 with a rocker-arm 19, which is fixedly secured to shaft 20. The shaft 20 is ournaled in the sides of the box 14. An arm 21, constituting a crank, is fixedly mounted upon shaft 20, Fig. 5, and loosely incloses the shaft or pin 22, which shaft 20 is journaled in the sides of the shoe 15. The operation of the lever 16 rocks the shaft 20, and by means of the crank 21 raises and lowers the shoe and confines the belt between the shoe 15 and the top or bottom of the box 14 sufficiently to apply the friction in any degree desired. This upward-and-downward movement, ihereinbefore referred to, is therefore caused by automatically or manually swinging the rocker-arm 19, thereby rocking shaft 20. The belt 7 then carries the box 14, and the carriage 3 attached thereto, at a speed corresponding to the friction applied. The lever 16 is operated longitudinally forward and backward, and the power-pulley 5 is revolved in the proper direction, so as to impart a forward movement to the carriage 3, and likewise a backward pull upon the lever 16 will apply the friction to move the carriage 3 backward. When the pressure either way is removed from the lever 16, the spring 23, pressing against the upper end of the rocker-arm 19,will throw the shoe out of contact, thereby placing said rocker-arm, preferably, in a vertical position.
The double-headed pin 24 passes loosely through an eye in the end of the rocker-arm 19, and said pin 24 upon each side of rockerarm 19 is surrounded by a coil-spring 24. 1 The arms 26, carried by the frame 2, serve as stops to stop and reverse the movement of the carriage. When the pin 24 strikes against the stop 26, one of the springs 24 is first com pressed, forming a cushion until sufficient pressure is applied to operate the rockerarm 19 and rock the shaft 20, causing the shoe 15 to press upon the belt for reversing the movement of the machine. An automatic safety-reverse is in this manner provided. Shoulder-bars 27 are carried by the ends of the shoe 15, Fig. 5, which bars constitute guiding means. These bars 27 travel up and down against the edges of box 14 to insure parallel movement of the shoe 15. In the drawings the said bars 27 are preferably attached by screws 28.
