E. F. SPAULDING.
' EMOTION CLUTCH. No. 265,170. Patented sept. 26, 1882.
To all whom it may concern:
UNTTED STATES ELJAH- F. SPAULDING, OF ERIE, PENNSYLVANIA.
FRlCTlON-CLUTCH.
SPECIFICATION forming part of Letters Patent No. 265,170, dated September 26, 1882.
Application filed April 5, 1882. (No model.)
Be it known that I, ELIJAH F. SPAULDING, aeitizen of the United States, residing at Erie,
Erie county, Pennsylvania, have invented newV and useful lmprovementsin Friction-Clutches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and the letters -or gures of reference marked thereon.
My invention consists in providing a newand improved friction-clutch for use on various kinds of machinery.
The objects, purpose, and .scope of my invention will fully appear in thefollowing general description.
My invention is illustrated in the accompanying drawings as follows:
Figure l is a front elevation of my clutch, with the belt-pulley to which it is connected in vertical section. Fig. 2 is an end view, the shaft being in section; Fig. 3, an enlarged view, and shows an alternative construction of some of the parts. The clamp is here shown in section on the line ma; in Fig. 4. Fig. et is an end view ofthe saine construction shown in Fig. 3, the shaft heilig sectioned on the line y y in Fig. 3.
EO u
The various parts are lettered as follows:
A s the shaft; B, the belt-pulley or 4other gearing to be clutched to the shaft.
G is the clutch or clamp ring.
l D and E together form a'toggle'lever, D being acam-lever, and E E being links connecting said cam-lever with the opposite end of the clampiring, which end I call the head,77 while the end C' I call the toe,77 of the clampring.
G is the bolt or screw by which the clamp is attached to the gear or pulley.
F is the shifting collar, which in the construction shown in Figs. l and 2 Vis a cone, while in Figs. 3 and et it is a plain collar carrying an arm,f. are essentially the same, the difference being only in the means used for tripping the eamlever D.
My clutch consists of the clamp-rin g C, which is made of spring-steel, and the means employed for elampiu g it upon the shaft ora eollar, A', keyed to the shaft.
The two constructions shown The means for drawing the clamp-ring together consists of the links E E and the eamlever D, which acts upon the' toe C of the Vclamp-ring C. In the construction shown in Figs. l and 2 the longend of the camlever D is bent and runs out along the middle of the shaft, and is provided with an adj ustingscrew for bearing upon theshifting cone. W'hen the cone is shoved under the end of the lever it raises it, and the short eudor cam presses the toe of the clamp-ring toward the head, thus clamping the ringupon the shaft and. clutching it. This construction is desirable when it is desired that the clutching be donc gradually. The construction shown in Figs. 3 and l is intended for use when the clutching is desired to be instantaneous. In this construction the end of the cam-lever D lies in a slot in the ring C and runsin a groove in the shaft. (See A.) The shifting-collar F has an arm,
j', which lies in a longitudinal groove in the shaft, and when itis used to trip the lever D it slides across the groove A and passes under the lever D as the shaft revolves.
The clamp-ring C can be used as a' shaftcoupler, if desired, by using a screw similar to cl to bear against one of the parts and lift the Alever D, so as to grip the ring to the shafting. i
One of the advantages of my clutch is that it can be used on small gears and have allthe power it would on a large one. The clutch is very powerful. It may be used for attaching pulleys and gears to the shaft by using the screw in the end of the lever, as above described.
I am aware of clutching-rings having their ends connected together by links vand operated by a lever which forces the links upwardly and causes the ring to clutch the shaft or part surrounded by it. This device, however, differs from mine, n that my lever forces the ends toward each other and causes the ring to clutch a greater area and more firmly than in the devices above referred to, in which the upper part of the ring is lifted from the body. Therefore What I claim as new is A clutching device consisting of part C, en circling the body to be clutched, and having a IOO projecting lip, C', of links attached to one end have hereunto set my hand this 17th day of of part G Iind transversely crossing lip C and February, 1882.
connecting with lever D, havin one end in contact with lthe operative meohnism which ELIJAHF' bPAULDING' 5 draws the ends of part C together, for the Witnesses:
purpose set forth. JNO. K. HALLOCK,
In testimony that I claim the foregoing I W. S. BROWN.
