Title: Predetermining mechanism for liquid-dispensing meter assemblies
IPC: G01F15/10
Filed: 1952-09-25
Abstract: 715,668. Dispensing liquids. ROCKWELL MANUFACTURING CO. Sept. 25, 1952 [Dec. 13, 1951], No. 24037/52. Class 116 [Also in Groups XXIV and XXIX] In liquid, e.g. petrol, dispensing apparatus a valve 24, (see Group XXIX), opened by a hand lever 210 acting through a shaft 204 which carries a lever 218 connected by a link 300 with a valve lever 102 is held open against a tension spring 312 by engagement of a detent 256 with a projection 240 on an arm carried by the shaft 204 and is permitteed to close in two steps on completion of the delivery of a predetermined quantity of liquid through a meter 10 which actuates a presettable register 22 driven through a shaft 14 by the meter. The first step in the closing of the valve takes place when all but a certain amount of the predetermined quantity has been delivered and consists in the release of the projection 240 by the detent 256 and the subsequent engagement of the latter with a second projection 242. During this movement a dashpot controls the rate of closure of the valve. On completion of the total delivery the projection 242 is released and the valve closes without dashpot action. Opening of the valve, effected by clockwise movement of the shaft 204, operates a cam lever 270 which is connected through gearing with the shaft 204 and engages a roller 290 on an arm 278 pivoted at its lower end, to move a bar 336 to the left enabling the detent 256, which is carried by a lever 246, to engage the projection 240. In the fully open position of the valve the cam lever 270 is situated beyond the roller 290 in the position indicated by chain dotted lines. The bar 336, however, is retained in the leftward position by a detent mechanism 18. A disc 394 slidable vertically on pins 396 engages a tube 390 which, when depressed, releases the detent mechanism 18. The register, which is angularly adjustable through 180 degrees to be observable from either side of the apparatus and is connected to the shaft 14 by gearing (see Group XXIV) which permits such adjustment without altering the reading of the register, carries a plunger 482 which coacts with the disc 394. When a certain amount of the total quantity of liquid to be delivered has passed through the meter, say 970 gallons in the case of a total of 1,000 gallons, rollers (not shown) will engage aligned notches in the digit wheels 448 of the register to cause the plunger 482 to depress the disc 394 and release the detent mechanism 18 whereby the bar 336, under the action of a spring 352, releases the detent 256 from the projection 240. As the cam lever 270 returns towards its initial position it again engages the roller 290 and resets the bar 336 so that the detent engages the second projection 242 until the total quantity has been delivered when a second notch on one of the digit wheels is aligned with the notches of the other wheels and the rollers again cause the release of the mechanism 18 to permit the final closure of the valve. The valve may be closed at any time by operation of a knob 296 to release the de tent 256.

Title: Improvements in lubricating cups
IPC: F16N11/04
Filed: 1926-09-29
Abstract: 277,503. Fredericks, E. Sept. 29, 1926. Force-feed lubricators.-The expulsion of grease from a cup is effected bv a combination of spring pressure and air pressure generated by the action of assembling the parts of the cup. A hollow plunger f is arranged within a member c slidable in the cup a, a spring d being positioned around the member c between a flange c<1> thereon and a nut e screwed on the cup. A capillary opening f<1> in the upper face of the plunger places the interior of the plunger in communication with the closed air space above it. When the cup has been charged, the act of assembling the parts causes the air above the plunger and the spring to be compressed. To facilitate assembly, a split-ring g encircling the member c is arranged between the nut c and a lock nut h having a tapered recess, whereby the nut h can be screwed down on the nut e to force the ring g into a groove on the member c so as to hold the spring compressed. After assembly the nut h is eased to release the ring. To facilitate withdrawal of the plunger f from the member c, the lower face of the plunger is provided with a handle k and a valve l which can be pushed in to admit air above the plunger. An eye m is provided on the upper face of the plunger for the insertion of a hook in the event of the plunger sticking to the grease in the cup.
