SPECIFICATION forming part of Letters Patent No. 241,652, dated May 17, I881.
* Application filed April 6,1881. (No model.)
-To all whom it may concern:
ary 14, 1851; and it has for its object to provide means whereby the reciprocating motion is active to produce the rotary motion at every point of the revolution. This means consists, principally, of an auxiliary cross-head or similar device applied to the main cross-head,
which has independent forward and rearward motion at the ends of the stroke, in connection with levers pivoted to the oscillating bar for transferring the force at the beginning of the reverse movements above or below the plane or direction of reciprocation.
The invention further consists of means for locking the auxiliarycross-head with the main cross-head; of the auxiliary cross-head, the main cross-head, and the oscillating bar or lever, in combination with the hinged levers, the
oscillating bar being pivoted in the main crosshead and also in the parts last stated, in combination with the revolving shaft provided with two cranks at or near right angles to each other, and connecting rods connecting the cranks with the ends of the rocking or oscillating bar, all'as hereinafter fully described and claimed.
In the accompanying drawings, Figure l is a plan view of my invention. Fig. 2 is a longitudinal section of the same, taken on line at w of Fig. 1. Fig. 3 is a cross-section taken on the line 51 y of Fig. l; and Fig. 4 is a transverse section of the cross-heads, showing the auxiliary cross-head locked with the main cross-head.
Similar letters of reference indicate corre sponding parts.
The ways A A, upon which the cross-heads move, the shaft B, carrying the fly-wheel D, and provided with the double cranks E E,the connecting-rods F F, and the tie-rod G of the cranks are of the same form and construction as described in the Letters Patent above mentioned; and the oscillatingbar Cand the main cross-head H are also of the same construction described in said patent, except that instead of the main cross-headmovingin contact with the Ways A A the same is constructed to be moved within and by the auxiliary cross-head J, which surrounds it, and that the oscillating bar is provided with the pivoted levers L L at its upper end.
The auxiliary cross-headJ is of suchlength relative to the length of the main cross-head that the same is adapted to have an independent long stroke-that is to say, a longitudinal movement at the ends of the stroke which is independent of the movementof the main crosshead, and the ends of the auxiliary cross-head are formed or provided with the grooves or other suitable stops, (1 d, with which the notched ends of the levers L Lalternately engage while the cross-head is traveling the space of its independent movement. By this means the force during the independent movement of the auxiliary cross-head is transferred through the pivoted levers L L to apoint above the plane of reciprocation, and applied to the cranks of the shaft through the oscillating bar 0 and the connecting-rods at a point above the line of dead-center. It will be understood that during this time the main cross-head remains at rest, and that the motion of the oscillating bar is only upon its pivot.
When the main cross-head and oscillating bar begin to move, the levers L L are thrown out of engagement with the notches by coming in contact with the arms or projections Q Q, which are secured in proper position for that purpose upon the ways A A, as shown.
After sufficient motion has been obtained, so that the momentum will carry past the deadcenter, the auxiliary cross head should be brought to its short stroke by placing the blocks P 1? between the cross-heads, as shown in Fig. 4, which look the two cross-heads together, in which position they act as a single cross-head. These blocks maybe attached to and operated by suitable levers attached to the machine, by which means the movement of the auxiliary cross'head would be under easy and sudden control. 7
Though I have shown my invention applied only to the upper end of the oscillating bar IOC ' and adapted to revolve the shaft in one direction only, it is obvious that, by attaching 1evers to the lower end of the oscillating bar and providing spring or other suitable mechanism for causing the ends thereof to engage with suitable notches or projections on the under side of the auxiliary cross-head, the action of the auxiliary cross-head would be applied in like manner to the lower end of the oscillating bar, and thus render the shaft reversible.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The sliding cross-head H and the oscillating bar 0, in combination with means, substantially as shown and described, for transferring the reciprocating force at the beginning of the reverse movements above or below the plane of reciprocation, substantially as set forth.
2. The auxiliary cross-head J, havinga longitudinal movement at both ends of the stroke independent of the main cross-head, in combination with the levers L L and the oscillating bar 0, substantially as and for the purpose specified.
3- The auxiliary cross-head J and the main cross-head H, in combination with the removable blocks P P, substantially as and for the purpose specified.
4. The auxiliary cross-head, the main crosshead, the former having movement independent of the latter, the oscillating bar 0, and the hinged levers L L, in combination with the shaft having the cranks E E and the connect- 3 5 ing-rods F F, substantially as and for the purposes specified.
