Specieation of Letters Patent. Y Patented NOV. 11, 1919.
Original application filed March 1, 1917, Serial No. 151,661. Divided and this application filed September 6, 1917. Serial No. 189,980.
To all whom t may concern Be it known that I, ARTHUR A. AUST, a citizen of the United States, residing at Bedford, in the county of Cuyahoga and.
pump chamber is provided with a rotatable ring operated by two rotating pistons. The relation between the ring and the pistons is such that power is applied to the end of the piston rods thereby securing maximum efliciency. The ring is tangent to the inner surface of the chamber and always engages the point of tangen'cy. The piston rods are eccentric n relation to the movement of the ring and in rotating presses against the inner surface of the chamber. l is provided with suitable openings for admitting and expelling the water.V
Other details will be pointed out* in the description to follow. My invention is `illustrated in the accompanying drawings, wherein:
Figure 1 is an end sectionalview of the pump mechanism. A
Fig. 2 is a section showing the details of the pump mechanism with the pistons in alinement. n
Fig. 3 is a section on the line 18-18 of Fig. 2. u
Fig. 4 is a detail of one of the pump pistons. Fig. 5 is a detail showing a modified form of piston.
Referring to the drawings, the main shaft 320 carries the collar 310 which is fastened to the rod 312, one end of which is threaded into the collar as shown` in Fig. 4:. YThe opposite end of this rod 312 carries the piston 333 at X, which in rotating presses against the walls and inner circumference of the cylinder or chamber. During this rotation the piston 333 carries with it the movable The chamber ring 321. This ring is provided with the roller bearings 322 which rest upon or engageV the periphery of the flange 336.
y The ring 321 is centered eccentrically in relation to the shaft and is provided with an extension or ring-shaped section 337 through which the rod 312 passes. Within the ring 337 is mounted a rotatable split ring 330. This ring 330 is arranged to rotate in order to take up the variation of the piston 333, which as stated is eccentric in relation to the center of the ring 321.
The ` rings 330 and 337 are shouldered downto reduce friction. The opening 331 in the ring 337 through which the rod 312 passes is provided With enough clearance to permit the eccentric movement of the piston 333 and the corresponding movement of the arm 312. As the ring rotates the piston 333 slides back and forth through the close ,fitting opening 332 in the ring 330.
It will be noted that the piston 333 designated as X is mounted upon and keyed to the shaft 320. The other piston 333 instead of being fastened to the shaft is mounted or attached toa rider or idler arranged to turn loosely upon the shaft 320. The idler 340 shown in Fig. 3 is provided with the yokes or rings through which the shaft 320 passes. The ring or bearing to which the pist-on 333 designated as X is mounted lies between the rings 3411 and 342 of the idler. From this arrangement it will be seen that the piston 333 designated as X is operated directly by the shaft 320, while the other piston 333 turns freely upon the shaft. The ring 321, is however, provided with two split rings or collars 330 through which both pistons pass.
`With this arrangement the shaft 320 in rotating carriesv with it the piston 333 at X which causes the ring 321 to rotate. This ring in rotating carries with it the other piston 333 which is loosely mounted upon the shaft. This arrangement is necessary as the center of the ring 321 is eccentric to the center of the shaft upon which the two pistons are mounted. In View of this ec centric relation it is necessary to make allowances for thepistons to assume the positions shown in Fig. 1 when the maximum volume 0f water lies under and between the two pistons.
Referring to Fig. 2, it will be noted that the two pistons are in line and the center of the shaft 320 is directly in line with the 1'8-l8(y In Athis position the chan'iber is tin'g'ency1 the'l'eaf valves shown inv Figs. 2;,
