Specification forming partof Letters Patent No. 13] ,9&0, dated October 8, 1872.
of a pair of steam-engines to a shaft, a portion of the front part of the frame being broken away to show the crank and Figs. 2, 3,
' 4, and 5 are diagrams, showing the relative positions of the vibrating beam to the crank points in the revolutions of the Like letters refer to like parts in each ligure.
This invention relates to a newmechanical movement having for its object to utilize the full power of the motor to propel a crank past the dead-centers; and it consists in a crosshead moving in slides above or below the crank of the driven shaft. This cross-head forms the center stud for an oscillatingbeam, to each end of which a steam-engine or other reciprocating motor is attached, the valves of one of the engines being set so as to give it a lead of about one quarter` in advance of the other. A-pendulum at a right angle with the beam is strapped to the wrist of the crank, the effect of which is that both `motors are exerting their power to carry the crank past the dead-centers, and thus utilize the full power applied or developed, less the constant" co-effcient of friction.
In the drawing, A represents a bed plate, on which are erected two upright frames, B B',
`the upper parts of which terminate in the vertical guides G. In the lower part of the frame B is the end plummer-block or bearing of theV shaft D, which is to be driven. E is a crosshead, or, more properly, the center stud of the vibratingbeaml El. The ends of the stud are stepped in the slides F, whichhave a vertical e movement in the guides. A reciprocating engine is connected with each end of the beam through links ora connectingrod. The valves of one engine are so set as to give it an advance or lead over the other one, as hereinafter described. Pendent from the eenterof the beam, and perpendicular thereto, is a pendulum, E2, which has the wrist a of the crank G journaled in its lower end, said crank being keyed on the end of the shaft D. E3 are two diagonal braces between the 'lower end of the pendulum and thebeam ends, to stren gth en the former.
The beam is moved bodily up and down in the reciprocation of the engines which are connected thereto 5 and, as before explained, the valves of the engines are set so as to give one of, them a lead, which gives the beam an oscillatin g movement as the crank-centers are passed. At this time one of the engines has not completed its up stroke, while the other will have completed the up stroke and commenced the down stroke. At the upper and lower centers of the crank the beam will be in a horizontal position, but at no other time. By referring to the diagrams of the annexed drawing it will be seen that while the crank is on the lower center, as in Fig. 2, the righthand engine is pushing up its end of the beam, while the lefthand engine has yet to complete its down stroke and shift the positions of the beam and crank, as shown in dotted lines in said ligure and in Fig. 3, both engines exerting their power to carry the crank past the center.
Figs. 4 and 5 show the relative positions of the parts at the upper center of the crank and at the commencement of the down stroke of both engines.
The cylinders may be placed under the beam or inverted above it, or they may be inclined in position, asV circumstances may require, without changing the principles involved in the application of the' new movement, or one motor alone may be used at one end of the beam, but in this case the dead-centers in the engine are not overcome, while those ofthe crankwill be in the positions shown in Figs. 3 and 4. This movement is applicable in very scribed, its center studE journaled in the said slides, and its pendulum I-.l2 strapped to the wrist of the crank G, al1 arranged and operating substantially as herein shown and described.
