R. ABRAMS DEVICE FOR MEASURING, REGULATING, AND METERING SUPPLY OR DISTRIBUTION 0F FLUIDS Filed July l, 1930 Patented Aug. 2, 1932 UNITED STATES PATENT CFFICE VICTOR n. ABnAMs, or BnqNswIcx, GEORGIA :DEVICE FOB MEASUBING, REGULATIN'G, AND METERING SUPPLY OR DISTRIBUTION 02|? FLUIDS Application led July 1, 1930. Serial No. 465,225.
This invention relates to improvements in devices for measuring, regulating and metering the quantity of fluid which will flow through an orifice upon the application of pressure to the Huid, and the primary object of the invention is to provide such a device as will accurately perform these functions without the us'eof valves such as are ordinarily used with any measuring piston driven by mechanical means.
A further object is to furnish a device of this character, inclu-ding a cylinder in which a plurality of pistons operate, the construction being such that at least one of the pistons will positively obstruct the bore of the barrel at all times to absolutely revent the passage of any Huid through t e device without proper functioning ofthe pistons.
A further object is to provide a device of go this kind which islof simple inexpensive and durable construction, land one in which the,
various elements may be readily assembled or dismantled to facilitate replacement of parts or cleaning of the device.
With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accom- '30 panying drawing, and more particularly pointed out in the appended claims.
Referring to the drawing,
Fig. 1 is a longitudinal Ysectional view of the device illustrated as interposed in a lubricating system, and with the pistons in the positions which they occupy when the structure is ready to be charged. Fig. 2 is a similar view of the device, but showmg the pistons in the positions they assume when the'device is charged.
Fig. 3 is a like view, but with the parts in the posltions they occupy during lthe discharge period.
Fig. 4 is an elevation. of one end of either piston.
My improved measuring, regulatmg and metering device may he employed in connection with any fluid, and is.-
like.
articularly use# ful when em lo ed inali u ipe line or the P y p pipe 15 through the Opclung. lj, I mu Pass In the drawing, 4 designates a cylinder having a bore 5, preferably of cylindrical shape, which merges at its ends into annular shoulders 6 and 7 that extend outwardly to cylindrical surfaces 8 and 9 that are of larger diameter than the cylindrical surface of the main portion of the bore.
AStop fingers 17 and 18 project inwardly from the caps and function to halt' the pistons 20 and 21, so as to prevent the same from seating snugly against the caps. Each piston has a cylindrical surface 22 which is interrupted by diametrically opposite notches or rabbets 23. The cylindrical surface is of such ldiameter as to snugly fit the cylindrical bore 5, and each piston is hollowed out to provide an internal socket 25. These sockets are of the same diameter as heads orV flanges 26 ar'- ranged on the ends of aconnecting rod 27. Stop pins 28 project radially through the pistons into close proximity with the rod 27, and the heads 26 are adapted to move between these stop pins and the heads of the pistons.
A coiled spring 29 is arranged in the cylinder and abuts at its ends against the inner ends of the pistons for the purpose of holding the piston 21 away from the piston 20, at a certain time. i
A stronger coiled spring 30 is` arranged in -the cylinder, and has one of its ends abutting against the cap mal position,1 this spring forces the same into 10, and its other end abutting the piston 20and when the parts'are 1n no'rthe position shown in Fig. 1, and maintains -the spring 29 under compression. A
. The operation of the de, c e-is asu'follows'. p 100.
When a pressure fluid i'sforcedby way of 4From such place, it will continue to flow y through the notches 23, into the space between the two pistons and will then actto force the piston 20 away from the piston 21. This action will continue until the abutment pin 28 of the piston 20 engages the head 26 at' the left endof the connecting rod, and while the piston 20 is V:moving in such manner, the spring 29 will prevent the piston 21 from disengaging the pins 18. As soon, however, as the abutment 28 of the piston 20 strikes the head 26 at that end of the rod, the latter will commencel to move with the piston 20, and such movementwill continue until the head 26, at the other end of the rod abuts against the pin 28 of the piston 21. As the pressure fluid continues to enter, the pistons will now move toward the left in unison until the parts reach theposition shown in Fig. 2.- At such time, the two pistons will be closing the ends of t-he bore 5, and the charge which is arranged in the bore between the pistons, will be an accurately measured one. For the purpose of discharging such charge, the introductioitof the pressure fluid is continued, and as it acts against the head of the piston 2l, it will cause the latter to exert pressure on the charge, and to force the piston 20 into contact with the stop fingers 17, and as the pressure is continued, the charge will be forced out through the aperture 13, and the parts will assume the positionl shown in Fi 3. As soon as the charge has been complete y transferred by the device, the pressure on the fluid entering through the aperture 14 is relieved, with the result-,that the spring 30 moves the pistons toward the right hand end of the cylinder, or back to the position shown inFig. 1,
v in which position, the parts will be ready to receive a second charge.
It will be. noted that this device employs no valves such "as are ordinarily used with measuring pistons driven by mechanical means. Furthermore, there is no time duri-'n0' its operation, when one or the other or both pistons are not in the bore 5. Consequently, there is absolutely no possibility of liquid passing through. the device without proper functioning of the pistons, and except "for 'leakage between the pistons and the bore 5,
'Y its action is entirely positive and independ ent of the pressure'fluid. In other words, it will deliver the same quantity of liquid at l0 pounds or 100 pounds, or will deliver the same quantity on practically an instantaneous pulsation, as it will supply on a relatively long period motion. vThis enables the device to machinery,
-be used at locations remote from the fluid pressure,such. as the individual bearings of and other places difficult of accontemplate its application for this purpose, particularly in the lubrication of the chassis of an automobile, also to line shafts, conveyors and other machinery which are inaccessible, but which by means of the invention, may be supplied by a trunk line arranged at a convenient point.
The invention will also be used for the measuring of fluids in industrial processes, in the dispensing of carbonated fluids for making carbonated beverages, inthe regulation and measuring of Syrups, oils and other liquids in the canning, packing and bottling industries. In short, I contemplate employing the device in any environment where it will b'e applicable. v A
From the foregoing it is believed that the construction, operation and advantages of the vinvention may be readily understood, and I am aware that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.
