ALLEVI ANNIBALE, OF CHICAGO, ILLINOIS.

LEVER-POWER ENGINE.

SPECIFICATION forming part of Letters Patent No. 483,776, dated October 4, 1892.

Application filed May 23, 1892. Serial No. 434,106. (No model.)

To all whom it may concern:

I 3e it known that I, ALLEVI ANNIBALE, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lever Power Engines, of which the following is a full, clear, and exact specification.

My invention relates to that class of motors known as lever-power engines, so called because of the levers embodied or employed therein for converting the rapid motion of some suitable driving motor or engine into greater power.

In lever-power engines as heretofore constructed the driving-motor in performing its function not only has to supply motion to the lever for causing it to act upon the driven shaft, but, in addition, has to raise such lever into position. for action, and as the levers are usually Very long and weighty the loss of power thus entailed is considerable.

The prime object of my invention, therefore, is to construct an improved power-engine in which the lever or levers shall always be in equilibrium.

A further object of my invention is to utilize the movement or stroke of the levers in both directions.

A still further object of my invention is to provide the lovers with a traveling fulcrum and to have the strain upon such fulcrum'at all times equal, and equal only to the weight of the levers and parts supported on the latter.

With these ends in view my invention consists in certain features of novelty in the con struction, combination, and arrangement of parts by which the said objects and certain other objects of minorimportance hereinafter described are accomplished, as fully explained with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side elevation of my improved engine, showing the belt by means of which motion may be transmitted thereto from any suitable motor or engine (not shown) and another belt by means of which the power of the lever-engine may be employed or put to use. Fig. 2 is a plan view of the same; and Fig. 3 is a vertical transverse section taken on the line 3 3, Figs. 1 and 2.

Like signs of reference indicate like parts throughout the several views.

In carrying out my invention I employ a frame or bed 1 of any suitable design and construction, upon which is mounted in suitable journal-boxes 2 a crank-shaft 3, on one end of which is secured a pulleywheel 4, While on its other end or other convenient place may be mounted an ordinary flywheel 5 for keeping up the momentum of the shaft 3, as will be understood. To the crank 6 of this shaft 3 is attached a double orbifurcated connecting-rod 7, whose bifurcations are pivoted at their lower ends, respectively, to two horizontal levers 8, the latter being fulcrumed on pins or pivots 9, journaled in suitable boxes 10, mounted upon the standards 11 or other fixed portion of the frame or bed.

Journaled upon the bed or frame 1, above the levers S, in suitable journal-boxes 12, is a shaft or pin 13, which constitutes a fulcrum for two crossed levers 14 15, such pin or shaft 12 passing through such levers preferably midway of their length. The upper ends of the levers 14 15 are connected together by two links 16 17, which are pivoted to the le vers 14 15, and are themselves connected or pivoted together at their upper ends, and the lower ends of the levers 14 15 are similarly connected together by similar links 18 19,the links 16 17 and 18 19 being connected, respectively, to the main power-levers 20 21 by any suitable means. Thus it will be seen that the weight of the lower power-lever 21 pulling downward upon the levers 14 15 will have a tendency to bring such levers into a parallel position and force the upper main powerlever 20 upward; but as this latter lever is equal in weight to the lever 21 it is obvious that it will exactly counterbalance such lever 21, and the two levers in consequence will remain in equilibrium in whatever position they might be placed. It will also be seen that when the levers 14 15 approach a parallel position they will cause the divergence of the main power-levers 2O 21, and, owing to the manner in which said levers 14 15 are connected to the main power-levers, the motion imparted to the latter by the levers 14 15 will be very great as compared with the movement of the levers 14 15. As a means of applying motion to these levers 14 from the crankshaft 3, I connect such crank-shaft through the medium of the connecting-rods 7 and the levers 8, already described, to one of the levers 14 15 by means of an arm or link 22. As shown in the drawings, such link 22 is pivoted at one end to the lever 15 about midway of its upper half and at its lower end to the levers 8 at or near their outer extremities. Thus when the crank-shaft 3 is rotated a reciprocating motion will be imparted to the arm or link 22, which will cause the levers 14 to oscillate to and from each other and produce the desired movement to the main' power-levers 2O 21 through the connections before referred to.

I have shown in the drawings, and I prefer to use duplicates of the levers 14 15, as illustrated more clearly in Fig. 3, and also duplicates of the links 16 17 and 18 19, as well as of the arm 22. The links 17 may be pivoted between the links 16 on a suitable pintle or shaft 23, and between the levers 15 on a similar pintle 24, and the levers 14 are preferably arranged between the levers 15, so that a suitable elastic bumper 25, arranged on the shaft or pintle 26 between the levers 15, will strike against the lower ends of the levers 14 when the levers 2O 21 come together, thus avoiding undue jar and also imparting to the levers 14 15 a tendency to assume a vertical or upright position. The links 19 are pivoted to the lower ends of the levers 14 on a suitable pintle 27', and the links 18 are pivoted to the levers 15 by pintle 28 and to thelevers 19 by pintle 29, the main power-levers 20 21 being pivoted on the pintles 23 29, respectively. WVhile I have been particular to describe these parts as double, it will nevertheless be understood that it would not involve a departure from the spirit of my invention to use single links, levers, and arms as they appear in side elevation in Fig. 1 instead of the double parts, such duplication being employed simply for the sake of greater strength and rigidity in the structure.

The main power-levers 2O 21 are fulcrumed at the upper and lower ends, respectively, of the upright brace 30, which is provided with a transverse shaft 31, constituting a crosshead sliding upon any suitable runway mounted upon the frame or bed 1. The ends of this shaft 31, if desired, may be provided with antifriction-rollers 32, having grooved peripheries engaging the upper and lower bars 33, constituting the runway. The short arms 34 35 of the levers 20 21, respectively, are connected togetherby a knuckle-joint 36, consisting of two links pivoted to the ends of the levers 2O 21, respectively, and connected together by a shaft 37, which constitutes a second cross-head and whose ends are provided with rollers 38 similar to the rollers 32, which play back and forth between the bars 33. Thus it will be seen that when the main power-levers 2O 21 oscillate to and from each meme other they will have a bodily movement onthe rollers 32, incident to the rising and fallin g of their pivots 23 24, in a strictly vertical plane, and, in addition to this movement, the cross-head or shaft 37 will have an independent forward and backward movement, due to the oscillations of the links constituting the knuckle-joint 36. Hence it will be seen that the movement of the crosshead 37 will be equal to its own individual movement induced by the knuckle-joint 36 plus the bodily movement of the levers 2O 21, resulting from the oscillation of their rear ends in a straight line. In order to utilize the power focused at the cross-head 37, I connect such crosshead to the crank-shaft 39 by means of a suitable connecting-rod 40, so that the power of the cross-head 37 may be transmitted to any desired machinery through the medium of a suitable pulley 41, mounted thereon,and belt 42 or other well-known form of gearing. The reciprocating connecting-rod may be provided with an eye 43 to permit the passage of the shaft or cross-head 31, and to allow such rod to be reciprocated by the movement of the cross-head 37 and to oscillate with the crank 44 of the shaft 39.

The cranks 6 and 44 are arranged on the quarter, as more clearly shown in Fig. 1, and

in order that they may retain this position with relation to each other I provide each of the shafts 3 39 with the sprocket-wheel 45 46, respectively, and connect these sprockets together by means of the sprocket-chain 47, thus preventing the cranks from getting on a deadcenter and also insuring the rotation of the crank-shaft 39 in the proper direction, it being of course understood that the stroke of the crank 6 is greater than that of the crank 44.

The levers 8 may be provided with a num ber of holes or perforations 48 to permit of variation in the relative length of the arms of such levers, and, if desired, the augmentation of this variation may be made possible by 10- cat-ing the crank-shaft 3 closer to the crankshaft 39 and employing levers 8 of greater length.

Motion may be imparted to the crank-shaft 3 through the medium of a suitable belt 49, connected to any appropriate source of power or motor, such as a small gasengine or the like. (Not shown.)
