The spring Tt is adapted to be placed in hub /t and against it rests the ratchet-wheel N. The stroke-pulley H consists of a series of concentric rings /zf z", which iit over the axis 7L. The disks S and S hold the cord g on the cord-pulley H, the disk S being' atlixed to the hub /L by screws s, and the disk S being' furnished with the screw a', by which it is screwed to the end 713, and with the lug's s, to which is attached the cord g. The hub l1, has its snrface adjoining the cam-wheel P in the form of a ratchetwheel for engagement with the spring-pawl 2f, iixed to the cam-wheel P to enable the operator to take up any slack in the cord leading' from the indicator-drum to the stroke-pulley and to hold the stroke-pulley in place. Mounted on the supporting-arm A is the post T, to which is fastened the stud o by the screw 02 and which is threaded at its upper end to receive the screw-bolt U, on which is mounted the pawl p and the spring' pi, actuating said pawl.

Then the machine is in operation, the two ratchet-wheels M and N are in close engagement and rotate tog'ether and the cam-wheels G and P are also in close engagement, but held from rotating by the stud o'. The pawl A' s in the slot gf. lVhen the lever-arm j) is pressed downward, the cam-wheel P moves upward, forcing the ratchet-wheel N out of engagement with the ratchet-wheel M and into the hub t, thereby compressing' the spring' R. The stroke-pulley H stops. The cam-wheel P is held open by the spring-actuated pawl p3 entering the slot p in said camwheel. The parts are so proportioned that the upward travel of the -am-wheel P is limited and the two cam-wheels O and P are never entirely outl of engagement. Normally the two ratchet-wheels and the two cam-wheels are held together by the spring' R, assisted to some extent by the pawl p3.

The parts are assembled as follows: To the back of the bevel-gear e is fastened the collar K by the screws Z? holding in place thehub L and carrying' the ratchet-wheel M.

Then

the cam-wheel O is put into place, encircling' the ratchet-wheel M and resting against the collar K. Then the stud f/ is placed in the slot 0 and secured by the screw 02. Then the cam-wheel P is placed on the cam-wheel O in close engagement therewith and encircling the ratchet-wheel M, so that the pawl p drops into the slot gf. Te now take the hub /t and place within it the spring' R and the ratchetwheel N, compressing the spring as described. The axis /1/ of the hub /Lv is now screwed into the hub L,care being taken to keep the ratchetwheel N tight against the compressed spring' lt, so as to enable us to screw the parts together. It is necessary to prevent the hub L from rotating during this process, and this is accomplished by turning the hub L until the small hole Z therein registers with the corresponding hole in the plate carrying' the bevelgear c and locking these two parts together temporarily by a pin, which is withdrawn when the hubs have been screwed together. The disk S is screwed to the hub 71,. The pulleys or rings 7L* /L are now mounted on the axis /L and the screw s' with the disk S screwed into the end zf.

Vhat T claim as m invention, and desire to secure by Letters Patent, is-- l. In a red ncing-wh eel as d eseribed, a clutch composed of two cam-wheels arranged on the stroke-pulley shaft, one cam-wheel being 1'0- tatable upon the other, said cam-wheels being normally held together by a spring' and said clutch being' operated by rotating' one cam-wheel upon the other against such spring thereby compressing it, together with such spring and with means for rotating' such camwheel; substantially as described` 2. In a reducing-wheel as describeda camwheel furnished with aspringpawl; substantially as and for the purposes set forth.

In testimony whereof I have aflixed my signature in presence of two witnesses.-
