Application tiled March 17, 1924. Serial N0. 699,957.
This invention relates to plunger pumps of the cam or eccentric operated variety and view of the pump showing the rolling cam Y -arrangement in section.
In the figures, (1) is a main body casting,
(2) a bronze cylinder lininghaving a ange (3) bolted to the upper edge of the body casting as shown. l v
Opening to the lower part of the cylinder are suction and discharge ports (4) and (5.) having suction and discharge valves (5') and (6) thereon, and over each valve is a cover'plate ('f) having one end slipped nut (14).
under a notch`(8) in the casting and the other end bolted'down by a bolt ing slots in both members for ease of removal, for gaining accessto the valves.
Within the Ibronze liner (2) is a plunger (l) having a cup washer (11) at its lower en e The plunger is elongated to provide a substantial guiding surface against lateral motion, and extending through it is a rod (l2) shouldered at (13) and bolted to it by the The upper end of the rodbears a platel (15) preferably hardened on its upper surface and below the plate is/an expanding spiral spring (16) reacting against the upper fiance (3) of the liner (2), and which normalyforces the plunger upward to operate the suction of the pump. l
The downward or power stroke is eiected by the action of a rolling eccentric ring 18) actuated by a shaft (19) having an eccentric (20) formed thereon surrounded by a roller bearing (21) within the ring (18).
F9) `enne Y The eccentric (20) on the shaft in revolving forces the ring (18) up vand down to actuate the plunger andin doing so the ring rolls back and forth on the surface of the plate (15). f
Figure 2 shows the opposite section of this Ycam ring arrangement.l with the parts described similarly numbered and also shows a- Hange (22) at each end of the ring for retaining the roller bearing in plage' within it and forming an enclosed grease or oil housing for the rollers. Tlese ianges are pressed tightly into the ring and fit close to a shou preventino displacement of the ring.
At (24 (24) are indicated the usual roller separators or cage,'and ati-(25) in ,one or both flanges is an oil plug or screw for Bearings(26)f(26) on the main body casting at both 'sides of the eccentric re- `volvably support theshat (19), which latter is rotated y any` of the usual means not shown as not being involved in the invention. f
der ,(23) around the cam thus removal to fill the bearing with oil or grease; A.
I am aware 'of cam and eccentric driven Y plunger pumps of this general type? but do .not know of any having the improved features of my pum including the enclosed roller bearing, sel -lubricating rolling ring, doing away with the destructive wiping action of cams and heretofore making it necessary to run such pumps with the cam surfaces submerged in oil.
(I claim:
In a pump, having a cylinder, a reciprocating pistonV in said cylinder and a piston rod, secured to said piston, a resiliently mounted plate secured transversely to the outerdend o said piston ro'd, a revoluble ring whose periphery contacts with theouter face of saidfplate, a rotatablel shaft transverse to `said rod, an eccentricrxedly secured to said shaft and disposed within said ring, a series of rollers between the eccen- 'tric andthe inner periphery of the ring and.
contacting with both.
