4 Claims. (Cl. 74-30) This invention relates to engines of the recipgears l2 and bring about rotation of the shafts l l rocating piston type and has for the primary in opposite directions. A rocker arm i3 is seobject the provision of means for converting recured to the shaft 9 and its ends are connected riprocal motion into a rotary motion with the to rack bars 14 by a pin and slot connection, as
elimination of the conventional crank shaft for indicated at [5. The pins of the pin and slot such a purpose and the disadvantages of such deconnections 15 are received by vertically arranged vice. guides I6 located in the base i for the purpose of With these and other objects in view, this inguiding the upper ends of the rack bars in a vervention consists in certain novel features of contical path but which will permit said rack bars struction, combination and arrangement of parts to swing towards and from the gears i2. The 10 to be hereinafter more fully described and teeth of the rack bars match the teeth of the claimed. gears. The reciprocation oi the pistons I brings For a complete understanding of my invention, about reciprocation of the rack bars l4 and durreference is to be had to the following description ing the power strokes of the rack bars they move and accompanying drawings, in which in a vertical path and being in mesh with the 15 Figure l is a sectional view taken on the line ars 12, impart rotary motion to the power deil of Figure 2 illustrating a crankless engine livery shafts II.

The tracks 49 contrating in dotted lines the disengagement of the meet with the tracks 8 at the ends thereof. The rack bar from a drive gear of a power delivery tracks and 19 are formed by providing i t e h ft, guides I7 grooves of proper shape. Rollers 20 Figure 6 i detail sectional vie taken n the are journaled to the lower ends of the rack bars line 6-5 of Figure l. and engage with the tracks l8 and I9. During Figure 7 is a detail sectional view taken on the the downward movement of the rack bars the li 1. fpl 1, rollers travel in the tracks 18 maintaining the Referring in detail to the drawings, the numerrack bars in mesh with the gears 2 and du a] I indicates an engine base having a removable the upstroke of the rack bars the rollers 20 travel pan 2 and supported by said base is a cylinder in the tracks IE! to disengage said rack bars from M block 3 having cylinders 4 grouped vertically and the gears I2. in opposed pairs.

The tension guides 2| are engaged by the cally mounted in the cylinders are pistons 1 prorollers 20 as the rack bars reach the limit of their vided with connecting rods 8 extending into the downward movement so as to shift said rollers base. A rocker shaft 8 is journaled on th base from the vertical tracks to the arcuately curved and has secured thereto a pair of connecting rod tracks and thereby br g about a quick disenarms "I to which are pivotally connected the coneasement of the rack bars from the ars i2.

The arms ID bring about recip- Pivotally mounted shifting elements 22 are carocation of the pistons of each pair of cylinders pable of moving into the arcuateiy curved tracks in the same direction to each other, as shown in IQ where they join with the upper ends of the Figure 2. The pistons of one pair of cylinders vertical tracks I8 and have secured thereto segreciprocate oppositely to the pistons of the other mental gears 23 which are in mesh with auX- pair of cylinders. iliary rack bars 24. The rack bars 25 are pro- 0 Power delivery shafts H are rotatably supvided with cam engaging elements 25 which ride ported by the base I in a plane below the shaft 9 on earns 26 secured to the shafts H. The rack and either of which may be employed as a power bars 24 are spring pressed to maintain the portakeofl' shaft. The shafts II are connected by tions 25 thereof in contact with the cams. The 55 portions 25 of the rack bars when engaged by the high faces of the cams swing the shifting elements 22 into the tracks l9 and in engagement with the rollers to shift the rollers from the tracks I9 into the tracks IE to bring about meshing of the rack bars H! with the gears I2. The earns 26 are so arranged that the shifting of the rollers 20 of the rack bars from the tracks I 9 into the tracks l8 takes place when the rack bars l4 reach the limit of their uppermost position.
From the foregoing description taken in connection with the accompanying drawings it will be seen that a very efiicient, practical and economical means has been provided for converting the reciprocating motion into a rotary motion and is especially adaptable to engines of the reciprocating piston type whereby the motion of the pistons Will impart rotary motion to a power takeoff shaft with minimum vibration and wear on the various parts.
