SPECIFICATION forming part of Letters Patent No. 361,305, dated Aprl1 l9, 1887.

Application filed September 29, 1886. Serial No. 214,884. (No model.)

To all whom it may concern:

Be it known that I, FERDINANDO LUCHINI, a citizen of the United States, residing at Natchltoches, in the parish of Natchitoches, State of Louisiana, have invented certain new and useful Improvements in Marine Motors, of which the following is a specification, reference being had therein to the accompanying draw- 1ngs.

This invention relates to certain improvements in marine motors; and it has for its objects to provide a motor for forcing air automatically into the boilers of marine engines, to be employed instead of steam, or for working the ships pumps to pump water in a similar manner, all as will be more fully hereinafter described and explained, and specifically pointed out in the claims.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which-- Figure 1 represents a plan view of my improved motor; Fig. 2, a side elevation of the. motor proper; Fig. 3, a perspective view of a modification thereof as applied to the pumps for pumping water. Fig. 4 is a detail view, side elevation, of the ratchet-wheels, ratchetlevers, shaft, &c., parts being shown in dotted lines. Fig. 5 is a detail perspective of one set of the ratchet-wheels, ratchet-levers, and the shaft to which said wheels are secured.

In the drawings, A indicates a suitable platform, by which the various working parts of the motor are supported.

A indicates a pendulum composed of a heavy weight, to be set in motion by the rock ing of the vessel when at sea. The said pendulum is connected to a rod, 0, which is terminated at its upper end by a ball, B, working in a spherical socket, B, the ball being thus suspended so as to permit the pendulum to oscillate freely.

To the rod 0 is attached a circular table or plate, D, which has four equidistant sockets, E, near its outer edge. To these sockets are secured the articulated rods G, which terminate at their lower ends in ballsr, working in said sockets E in such manner that the said rods will be moved vertically back and forth as the pendulum oscillates. The rods G at their upper ends connect, by means of knucklejoints d, with the vertically-sliding guides F, (four in number) the said rods being arranged to slideon the vertical guide-rods F, depending from the supporting-plate A. Each guide F has pivoted to it at d two ratchet-levers, m and n, which are vertically operated in unison as the vessel oscillates in connection with the springs J to engage and disengage the ratchetlevers and corresponding wheels,M N, mounted on the shafts H, so as to give a rotary motion in one direction to the same. The springs J are connected with guides a: 'l, traveling be tween guide-bars z. Said guides are connected by means of chains w to a drum, W, mounted on a shaft, I, the said drum being provided with a. wheel, W, by which it may be partially turned, for the purposes more fully hereinafter explained.

The shafts H, which are four in number,

are provided with beveled gear-wheels P,

which may be adapted for constant'engagement with each other, as shown, or may be, by any ordinary clutch arrangement, adapted to be thrown into or out of gear, as desired. This latter adaptation is in no way, however, essential to my invention.

The ratchet-wheels M and N are rigidly engaged to their respective shafts-that is to say, each shaft H is provided with two ratchetwheels, M and N, rigidly secured thereto. Said wheels lie close together. The distance between the two wheels conforms to the distance between the two ratchet-bars m and n. The teeth on said bars are on the outer sides thereof, so as to engage the ratchet-wheels to which they are normally placed in close proximity. The teeth on thebar minclineupward, and the teeth on the wheel M are inclined so as to lock with said bar on the upward stroke when the two are placed in contact.

It will be observed that when the bar at is thrown into contact with the wheel M and the bar moved upward, such movement imparts a rotary motion to the ratchet-wheels, the series of shafts H, and the connecting bevelgears. The rocking of the vessel causes the pendulum to oscillate, transmitting a vertical reciprocal motion to the ratchet-bars m and a. The tendency of these bars is toward the ratchet-wheels. This tendency is imparted by the series of spiral springs J. The outer end of each spring is secured to the outer part of the frame,while the inner end thereof is engaged with the upper end of one of the bars at or a. The inner end of each chain 20 is secured to the drum \V. The drum in turn is loosely mounted on the vertical central shaft, I. The hand-wheel \V is rigidly fixed to the drum 'W'. The outer end of each chain 10 is secured to the upper end of one of the ratchetbars. Now the arrangement is such that when all the parts are in their normal position both ratchet-bars will be disengaged from the ratchet-wheels. Theinner ends of each set of chains (two constitute a set) are secured to the drum about ninety degrees from each other. The object of this is that when one chain of a set is out toits fullest extent, the rack-bar secured thereto will be in engagement with its respective ratchet-wheel. The other chain of said set at the same time being wound to the ex tent of one-fourth of a revolution of the drum, will hold its ratchet-bar in and away from its respective ratchet-wheel, thus permitting only one ratchet-bar and one ratchet-wheel of a set to engage and operate at a time; and, further, the arrangement is such that every bar in and ratchet-wheel M work together-that is to say, to engage or disengage one set M in is to engage or disengage allof the four sets M m. The same is true of the bars a and ratchet-wheels N. It will be observed that the ratchet-bars m engage the ratchet-wheels M on the upward stroke of said bars,while the bars a and ratchetwheels N engage on the downward stroke of said bar. Both bars cannot operate on the wheels M and N at the same time, but both may be thrown out of contact with thewheels, and so held out of contact. \Vhen the ratchets M and m are engaged, the shafts H are rotated in one direction, and when the ratchets Nand a are engaged said shafts are rotated in an opposite direction. The engagement and disengagement of the ratchets are effected by turning the hand-wheel IV. This wheel, op-

erating through the medium of the drumVV and chains, aetuat-es the ratchet bars, whereby either bar may be thrown into contact with its respective wheel, or both disengaged. The shaft I is fixed, while the drum \V is loosely mounted thereon. K represents a locking-bar pivotally secured to the shaft I. This locking-bar is adapted to engage any one of the series of recesses K in the upper outer edge of the drum WV, whereby said drum and connected parts may be locked to the shaft I, and the drum, chains, and ratchet-bars held in any desired position.

Thus it will be seen that in whatever direction the pendulum may swing it will, if the bars and wheels in M are in engagement, drive the power-wheel X in the direction indicated by arrow 1 in Fig. 1. Upon the pendulums return strokc the wheel will be driven in the same direction, the bars and wheels m M, which are in front of the pendulum-i. 0., upon that side toward which the pendulum is swing1ng being locked for the transmission of power, while behind the pendulum the bars lit slip over their corresponding wheels. M. In the case of the engagement of bars and wheels at N, those sets which are in front of the pendulum will slip relative to each other, while those behind will be locked. The wheel X will in this latter case turn in the direction of arrow 2 constantly, with the exception of the mo mentary pause when the pendulum is at the highest points of its are.

In the modification shown in Fig. 3 of the drawings the pendulum-rod G is suspended from a fixed point or socket, B, in a manner similar to that before mentioned, having a horizontal rod, 1, terminated by a cross-rod, Z, which latter will be elevated or depressed with each motion of the pendulum. The ends of said rod Z have connected to them, by balland-socket joints E, the vertical rods 00, which connect by similarjoints with the lateral rods 3 of the rock-shafts H, journaled in suitable pillow-blocks, H The said shafts H are provided with cross-rods (P, which have connected to them, by means of knuckle-jointsf the piston-rods of the pnmpsl? in such manner that as the pendulum oscillates the pumps will be operated.

Any suitable pump may be employed in connection with my device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, in a marine motor, of the oscillating pendulum suspended by a balland-socket joint, the plate attached to said pendulum, the connecting-rods secured to said plate by ball-and-socket joints, and the reciprocating guides and ratchet-levers and their springs, the whole arranged to operate substantially in the manner specified.
