UNITED STATES PATENT. OFFIOEQ FRANK J. TEMPLE AND JOHN HOEHN, OF DECATUR, ILLINOIS, ASSIGNORS TO UNION IRON WORKS, OF DECATUR, ILLINOIS, A CORPORATION OF ILLINOIS.
FRICTION-CLUTCH.
Specification of Letters Patent.
Patented 4 28, 1906.
and JOHN HoEHN, residents of the city of De- 1 ring catur, county of Macon, and State of Illinois,
have invented a certain new and useful Fricti on-Clutch, of which the following is a specification.
The object of this invention is toprovide a simple and powerful friction-clutch that may be easily and quickly thrown in and out of engagement and that may be readily adjusted to compensate for Wear.
The invention is exemplified in the structure hereinafter described, and it is defined in the appended claim.
In the drawings forming part of this specification, Figure 1 is a plan of a clutch embodying our invention, the flanged wheel being shown in section to expose the expansible ring therein. Fig. 2 is an elevation of the clutch, showing the toggle shifted to expand the ring. Fig. 3 is a face view of the expansible ring, showing a late removed from an end of the split part the ring to expose the ring-expanding agpliances therein. 7 Fig. 4 is a section on line in Fig. 3. Fig. 5 is a detail of the ring-expanding member of the toggle-joint.
The flange-wheel 2 is journaled loosely on shaft 1 and is formed with a hub or sleeve 3,
on which a pulley may be mounted and secured by means of a key in key-seat 4.
The hub 5 of the split ring is keyed onto the shaft, and the expansible extensions 7 of the ring are conjoined with the hub at a point 0 posite the split, as shown at 6 in Fig. 3. T e conjoining ends of the split ring are enlarged, as shown at 7, and are recessed, as shown at 8. The recesses 8 are formed in a face of the split ring, and cam-collars 10 have bearings in the recesses.
Arm 11 forms a member of a ring-spreading toggle-joint, and it has cams 11'', which coact with the cam-collars after the manner of a right-hand and left-hand screw-thread. A shaft 11 extends axially through the cam- The are tted onto the ends of the shaft.
cam-collars have plane surfaces 10 on o poslte sides of their mner ends, and these p ane 'the position shown in Fig. 1.
art of arm 11, and the cam-collars 10 faces fit snugly in recesses 8 to hold the collars from turning.
A collar 19 is mounted slidably on shaft 1 and is provided with a lug 20. Links 21 con nect pivotally with lug and with the swinging end of arm 11. A strap 22 loosely encircles collar 19 in an annular groove thereof, and it is supplied with trunnions 23. A shift-lever 24 embraces the strap 22 and engages trunnions 23 through slots 25. A pivotpin 26 on a fixed bar 27 forms a fulcrum for the lever 24.
The collar 19 is thrown to the position shown in Fig. 2 to spread the split ring into engagement with the flange-wheel, and the clutch is detached by moving the collar to The links 21 of the toggle-joint swing arm 1 1 on shaft 1 1 and the right and left screw-thread action of the arm on collars 10 forces the collars force the cam-collars endwise to an extent to cam-arm rotatable between the cam-collars make the clutch operative, and the lock-nuts for forcing the separated arms apart. are retightened. 3 In testimony whereof We sign our names in We claim as new'and desire to secure by the presence of two subscribing Witnesses. 5 Letters Patent FRANK J. TEMPLE. In a fr1ct1on-c1utch, a split ring havln a cam-collars in its separated ends, Wedges Se? JOHN HOEHN' behind the cam-collars crosswise thereof, Witnesses:
