PUMP OR MOTOR WITH OSCILLATING PISTON.

Specification of Letters Patent.
Patented Oct. 1'7, 1905.
Application filed April 3, 1905. Serial No. 253,531.
'1'!) at w/wm it may concern.-
Be it known that I, PIERRE SAMAIN, a citizen of the Republic of France, residing at No. 108 Rue Victor Hugo, (llamart, in the Department of Seine, France, have invented a new and useful Improvement in Pumps or Motors with Oscillating Pistons, of which the following is a specification.
This invention relates to an apparatus designed to act as a pump or as a motor in which the operative organ consists of a disk or piston which oscillates at the same time around one of its radii and around a diameter perpendicular to the said radius. Apparatus of this kind are known and are usually employed for fluid-meters. The apparatus which forms the object of the present invention is distinguished from those already known by the special constructions devised in view of its employment as a pump or motor.
Referring to the accompanying drawings, Figure 1 shows the invention in longitudinal section along the dot-and-dash line A B of Fig. 2. Fig. 2 shows a transverse section along the dot-and-dash line C D of Fig. 1.
As will be seen from the drawings, the apparatus comprises an oscillating disk or piston 1, mounted upon a spherical hub and provided with a segment 3. The piston 1 oscillates in the interior of a chamber formed of two parts united along the line C D. The ends 4 and 5 of this box are truncated and its side wall 6 is a part of a sphere. The oscillating piston 1 possesses a radial slot which engages the partition 7, inclosed in the two tapering ends 4 and 5 of the box, and passing from the spherical hub 2 to the lateral wall 6, in which it is also inclosed. On each side of the partition 7 large grooves 8 and 9 are cut in the wall 6 for the entrance and the escape of the liquid. The spherical hub 2 can oscillate with slight friction between two seatings provided in the ends 4 and 5 of the box. A rod 10 is screwed into the hub 2, and at its inner end it is hollowed out so as to lit upon a spherical pivot 20, the center whereof coincides with that of the hub 2. The spherical pivot 20 is, moreover, engaged in the end of a rod 11, screwed into a socket 12, forming an extension of the end 4 of the box."
The connection between the oscillating piston l and the controlling or controlled shaft 13 is effected by means of the rod 10, the outer end whereof 15 engages in the slot of the handle 14. A roller 23 serves to diminish the friction.- tact with or strikes against a piece 150, engaged in the bottom of the slot, and the control of this stroke or contact is effected by means of the screw 16. The bottom of the groove is formed by a surface forming an arc of a circle the center whereof coincides with the center of the pivot 20, so that the end of the rod 10 can move in the groove, gliding over the bottom thereof.
27 indicates a spring, of which one end is fixed in the bottom of the groove of the handle 14 and the other end rests against the end of the rod 10, and the spring has for object always to push the rod 10 toward the outside and to insure the contact of the disk 1 with the walls of the parts 4 and 5 of the box, while leaving a certain elasticity which enables the piston 1 to yield in the case of hard bodies passing accidentally into the apparatus. From this arrangement it results that the support of the oscillating piston 1 is effected by means of the pivot 20, the regulation of which for the purpose of keeping it in its place and compensating for wear is effected by means of the screw 11 and the screw 16, which form very resistant points of support, whereas the hub 2 oscillates between the ends 4 and 5 without wearing them. This arrangement is of great importance in consequence of the work to be done when the apparatus is employed as a pump or a motor. The piston 1 and the box 4 5 6, which surrounds it, are inclosed in an outer box or envelop composed of two parts 17 18, joined together by screws 19 with a fluid-tight washer 21. The box 4 5 6 is clamped between the parts 22.
' Lubricators 24 25 serve to lubricate the part 14, which is placed in a chamber filled with oil, and the pivot 20 is lubricated by means of channels cut in the rods 10 and 11. The tightness of the mechanism around the shaft 13 is insured by the stuffing 26. When the apparatus is to be used as a pump, the oscillating piston 1 is controlled by the shaft 13 and the liquid is aspirated through the opening 9.
It is to be remarked that the pressure of the liquid pumped tends constantly to press the disk 1 against the ends 4 5 of the box. The rod 10 is simply propelled by its engagement in the slot of the part 14; but in the case of a hard body, such as a pebble, being The end 15 of the rod 10 is in conintroduced into the pump the rod 10 can approach the axis of the shaft 13, and thus breakage of the organs be avoided,
What I claim is 1. In an apparatus with oscillating disk, the combination of the oscillating disk 1, a casing having two truncated ends 4, 5 provided with seatings between which is fitted the spherical hub 2 of the disk 1, with adjustable means for supporting the hub 2 of the oscillating disk 1 without transmitting the pressure to the seatings of the truncated ends 4, 5, substantially as set forth.
2. In an apparatus with oscillating disk, the combination of an oscillating disk .1 of a casing having two truncated ends 4, 5 provided with seatings between which is supported the spherical hub 2 of the disk 1, with an adjustable rod 11, a projection 10 adapted to strike against the handle 14 of the shaft 13 adjustable by means of a threaded envelop 16 so that the cap of the oscillating disk is held be tween two regulatable pieces 11 and 14 without pressing against the seatings of the tapering ends 4, 5, substantially as set forth.
3. In an apparatus with oscillating disk, the combination of a casing having two truncated ends 4, 5, of an oscillating disk 1 having a spherical hub 2 fitted between the two seatings of the truncated ends, of a projection 10 attached to the spherical hub connecting the disk to the handle 14 and of a spring 27 adapted to enable the projection to be pushed toward the center and of withdrawing it toward the circumference, substantially as set forth.
In testimony whereof I have signed my name to this specificationin the presence of two subscribing witnesses.-
PIERRE SAMAlN.
