REVERSIBLE LIQUID-MOTOR.
Specification of Letters Patent.
Patented Apr. 23, 1912.
Application filed December 2, 1910. Serial N o. 595,319.
To all whom it may concern:
Be it known that I, WILLIAM E. PEARSON, of Swampscott, in the county of Essex and State of Massachusetts, have invented cer tain new and useful Improvements in Reversible Liquid-Motors, of which the following is a specification.
This invention relates to that class of rotary liquid motors in which a liquid u der pressure is caused to impinge upon pis ns mounted in a rotary piston-carrier.
One object of the invention is to provide a reversible rotary motorof the class above referred to for utilizing the motive force applied thereto to the best advantage.
A further object of the invention is to provide improved means for controlling the operation and movements of the pistons.
\Vith the above objects in view the invention consists in the improved rotary liquid motor hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.
The invention will be clearly understood from an inspection of the accompanying drawing in which Figure l is a transverse, vertical section through the motor in a plane perpendicular to the axis of the machine; Fig. 2 is a horizontal section taken on the line 22 in Fig. 1; and Fig. 3 is a perspective view showing one piston, a follower, and the cams and cam rolls for controlling the piston.
As illustrated in the drawings the motor comprises a casing 1 having a base 2, by which it may be mounted upon any suitable support. One half 4 of the casing is semicircular and concentric with the axis of the shaft 6 of the motor. The other half 8 of the casing is semi-circular in cross-section, having its center located to the left of the axis of the shaft, as viewed in Fig. 1, a distance equal to the active depth of the pistons when in action; that is, the distance between the periphery of the piston-carrier 30 and the interior of the casing at the point 12. The casing is provided with passages 14 and 16 which extend from the same side of the vertical median plane of the casing. Eith e r passage may be the induction or the eduction passage according to the direction of rotation of the motor. The passages 14 and 16 terminate at their inner ends in ports 18 and 20, respectively, the inner extremities 22 and 24 of which are separated a distance apart equal to the distance between the longitudinal median lines of the outer peripheral faces of two consecutive pistons when they are in full action. That is, when any two consecutive pistons, such as 56 and 57, are in full action the longitudinal median lines or axes of their outer peripheral faces are tangent to or coincide with the inner edges 24 and 22 of the ports 20 and 18, re spectivel y, at the extremity of the major axis thereof, depending upon the shape of said ports. These median lines are located at the intersection of said outer peripheral faces with median planes passing through the pistons in the direction indicated by the dotted lines 19 and 21 of Fig. 1. The passages 14 and 16 are so located that the direction of flow of the liquid is substantially tangential to the pistons so that the force of the liquid is utilized to the fullest extent.
The shaft 6 is journaled to rotate in suitable bearings in the casing, and upon this shaft a rotary piston-carrier is mounted. This piston-carrier is substantially the same in diameter as and concentric with the portion 4 of the casing, and comprises a hub 30, a web 30 and a rim 30 The piston-carrier is provided with longitudinally extending grooves 32 formed in the rim and web there of in which pistons 33 are slidably mounted. The movements of these pistons are controlled by adjustable stationary cams 34 and 35. These cams are formed with laterally projecting studs 36 and 37 which extend through slots 38 and 39 formed in the end walls 40 and 41 of the casing of the motor. These cams are bodily movable for adjustment and are held in adjusted position by nuts 42 threaded upon the outer ends of the studs 36 and 37 and engaging washers 44. The cams 34 .and 35 are provided with slots 46 which receive pins 48 projecting inwardly from the end walls 40 and 41. These pins aid in keeping th cams in proper alinement. The cams 34 and 35 are enlarged at one end by arcuate surfaces 50 which are of such a shape as to control the movements of the pistons so that they will be held in action for the proper length of time.
Located between each piston and the cams is a separate independent follower 52 having its ends formed with trunnions 53 upon which cam rolls 54 are journaled to rotate. The cam rolls engage the peripheries of the cams 34 and 35 and are forced outwardly thereby, thus carrying the followers which force the pistons outward into engagement with the interior of the enlarged portion or active chamber 8 of the casing.
From the construction above set forth it will be seen that two pistons are always in action. As shown in Fig. 1 the piston 56 is at the center of the active portion of its travel, the piston 57 is substantially midway of the port 18, and the piston 58 is about to come into action. When the pistons 56 and 57 have rotated sufficiently to bring their peripheries or outer surfaces between the inner extremities 22 and 24 of the ports 18 and 20, the space between said pistons is filled with the fluid and they act as a solid, single piston. As soon as the piston 56 passes the extremity 24 the fluid is discharged through the port 20 and the passage 16, it being assumed in this case that the passage 14 is the inlet passage and the passage 16 is the outlet passage.
The cams 34 and 35 can be adjusted so that the pistons will properly co-act with the internal periphery of the enlarged portion of the casing 8 or the active chamber. There are no springs for acting upon the pistons which will lose their tension after a time and thus cause improper action of the pistons. The cams 34 and 35 are so shaped that when the pistons are opposite the small end thereof they are free to move inwardly out of engagement with the interior of the casing 4.
While I have illustrated and described a preferred embodiment of the invention, I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction shown and described, but
I'Vhat I claim is 1. A reversible rotary liquid motor, comprising a casing provided with induction and eduction ports, a rotary piston-carrier mounted to rotate within said casing and provided with grooves, a piston slidably mounted in each groove, a follower slidably mounted in each groove and adapted to engage the inner opposing face of the corre sponding piston, a pair of cam rolls mounted on each follower, and a cam adjustably mounted on the inner face of each end wall of the casing adapted to cooperate with said cam rolls.
2. A reversible rotary motor, comprising a casing having its end walls provided with slots, a rotary piston carrier provided with longitudinally extending radial grooves, a piston slidably mounted in each groove, an independent follower slidably mounted in each groove and adapted to engage the inner opposin face of the corresponding piston, a palr of cam rolls mounted on each follower, a cam mounted on each end wall of the casing adapted to be engaged by said cam rolls to force said pistons outwardly into active position, said cams having studs projecting through said slots in the end walls, and means on the studs to hold the cams in adjusted position.
A reversible rotary motor, comprising a casing, a rotary piston carrier provided with longitudinally extending radial grooves, a piston slidably mounted in each slot, an independent follower slidably mounted in each groove and adapted to engage the inner opposing face of the corresponding piston, a pair of cam rolls mounted on each follower, and a cam which is bodily movable for adjustment mounted on each end wall of the casing and having an enlarged arcuate portion for engaging the cam rolls to force the pistons outwardly during the active portion only of their travel.
4.

In testimony whereof I have affixed my signature, in the presence of two witnesses.
