1 Claim.
My invention relates to duid pumps.
An important object of my invention is to provide a fluid pump that is light in construction and of suiliclent durability to permit the same to eiliciently and efllcaciously perform its duties.
Another object o1' my invention is the provision of a uld pump that is compact in its construction to afford an eiiicient operating pressure.
Still another object of `my invention is to provide a fluidpump that is adapted to maintain a substantially constant pumping pressure at all times.
Yet another object of my invention is to provide a fluid pump that may be fabricated entirely of metal tubes and plates thereby eliminating the usual heavy castings and obtaining a iluid pump that is light in weight but that has in no way sacrificed strength or durability in its constrpction.
Other objects and advantages of my invention will be apparent during the course of the follow ing description.
In the drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,
Figure l is a longitudinal sectional view of a device embodying my invention,
Figure 2 is a transverse sectional view, taken on the line 2--2 of Figure 1,
Figure 3 is a vertical sectional view, taken on the line 3 3 of Figure 1, and
Figure 4 is a vertical sectional view, taken on the line 4-4 of Figure 1.
In the accompanying drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numerals I l and II designate longitudinally disposed parallel supporting members, here illustrated as I-'beams, and being provided with spaced transversely positioned supporting I-beams I2, I3 and- I4.
The numeral I5 designates a crankcase comprising arcuately formed plates I6 and I1 having the longitudinal edges thereof bent outwardly at right angles thereto to form the center flanges I1 and Il which are maintained in appressed relation by thethreaded bolts I9. Ihe ends of the plates I9 and I1 are formed with radial anges and 2l which receive the cupular end plates 22 and 23.
The supporting I-beams III and II with longitudinal extending rib portions 24 and 25 which. project into the casing l5 and support the pillow blocks 29 and 21 respectively. The space between the crankcase I5 andthe ribs 24 and 25 may be filled in with a welding material,
are formed (ci. los-2oz) or the like, in a manner whereby a fluid tight union will be formed therewith. The crankshaft 28 is mounted for rotation on .the pillow blocks 29 and 21 and the heads 29 and 30 are bolted', or otherwise secured, to the pillow blocks to hold the said crankshaft against displacement. I-beam supports 3| and 32 are spaced above the I-bearns I 0 and I I and supported by the transverse I-beams I2 and I3 forwardly of the crankcase I5. The pillow blocks 33 and 34 rest upon the I-beams 3I and 32 and rotatably receive the countershaft 35 which is held thereon against displacement therefrom by the heads 35 and 31. The end 35 of the countershaft projects exteriorlyof the cover 23 where it may be connected to any suitable source of power, and the inner end 39 of the said shaft carries the sprocket 40 which is connected to a sprocket 4I on the crankshaft 29 by an endless chain 42.
'Ihe plate I1 is formed at its middle with spaced laterally extending tubular cylinders 43, 44 and 45, a substantially rectangular casing 45 encompasses the cylinders, as illustrated in Figure 4, and the vertical supporting walls 41 aredisposed in tangential relation to the cylinders to support the same and to impart a substantial rigidity to the entire structure. The cylinders, casing and walls are formed from conventional structural tubing and plates maintained in proper association by means of welding, or the like. The eccentrics 48, 49. and 5I) are keyed for rotation to the crankshaft 28 and are positioned in aligning relation to the cylinders 43, 44 and 45. The cross heads 5I, 52 and 53 are reclprocally mounted in the cylinders 45, 44 and 43 and are connected to the eccentrics v48, 49 and 59 by the connecting rods 54, 55, and 56. The connecting rods are formed with ring portions 51, 59 and 59 which encompass the eccentrics and with laterally extending arms 60, 6I and 62, the extremities of whicnare pivotally attached to the cross heads by the wrist pins 53.
I'he iluid pump 64 is constructed from a plurality of seamless tubes welded, or otherwise secured together in the manner lhereinafter set forth. The transversely positioned inlet tube is supported on the bar 65 which is welded or otherwise secured to the supporting I-beams III and II. The end 61 of the tube 55 is closed and the end 69 thereof is provided with a radial ilange 69 for connection to a pump line (not shown). The vertically disposed tubes 10, 1I and 12 are welded to the inlet tube 65 and communicate therewith through the passages 13 in the valve seats 14 which are threaded into the lower ends 2, .of the pipes le, ll and l2 and support the valves l. The seats l have been made removable so that they be easily replaced when they be come worn or pitted. The upper ends of the tubes lid, 'il and l2 are connected by transversely posi tioned tubular members 'le and lll which com municate with the upper ends of the said tubes through the ports it. The removable valve seats l@ are threadedly received by the vertical tubes lil, ll and l2 subjacent to the ports ld, and the valves 8@ are seated thereon to control the ow of the uid into the discharge opening @l in the upper portion of the middle tube il. The upper extremities of the tubes lll, il an'd l2 above the ports it are closed by threaded plugs b2 which are removable to permit ready access to be had within the tubes. The laterally extending tubular cylinders 03, tl, and b5 are welded to the vertical tubes it, il and l2 respectively, and communicative therewith intermediate of the valve seats le and i9 and the outer ends thereof receive supporting plates d6, 8l and 88 which are held in abutting relation by angle clips tu. 'llhe transverse tubular cylinders b3, 84 and b5 are supported in longitudinal alignment with the crankcase cylinders 433, 4d and 135 by the transverse I-beams lll.
The fluid pump, hereinabove described, may be fabricated from tubing welded together to form a light, compact structure.
The pistons B, Si and 92 are secured to and actuatedby the crossheads 5|, 52 and b3 and the free ends 93, 9d and 95 thereof are reciprocally received in the lateral pump cylinders 83, 84 and 85. The outer ends of the crankcase cylinders are enclosed by front plates 95 which carry packing glands 91 to prevent fluid within the cylinders from escaping therefrom, and the plates 66, 8l and 88, carried by the pump cylinders 33, tft and 85, are provided with packing glands 08 which provide a uid tight engagement between the pistons and the said cylinders.
The oil. pan 99 is disposed above the crankcase cylinders 43, 44 and 45 and the top surface of the casing 46 constitutes the bottom of the oil pan; the plate constitutes the top portion thereof, and the vertical side walls |0| and |02 receive the countershaft 35 innerjacent the pillow blocks 33 and 34. The plates |00, |0| and |02 are welded to the casing 46 to deiine a fluid tight receptacle. A tubular member |03 encloses the portion of the countershaft intermediate of the end walls |0| and |02 and has its either end thereof welded, or otherwise secured, to the inner face of the walls. The top portion |00 of the oil pan is provided with a filler tube |04 by which a suitable lubricating uid may be introduced therein. The 'bottom of the oil pan is provided with discharge ports |05 which communicate with longitudinal grooves |05 in the crossheads 5|, 52 and 53 to lubricate the same, andthe inner ends of the grooves |06 communicating with the wrist pin connections through the lubricating ports |011. The arms 60, 6| and 62 of the accesos connecting rods are provided with longitudinal grooves leb either end oi which terminates in oblique lubricating bores its and il@ which communicate with the peripheries of the eccentrics and the wrist pin connections respectively. The lubricating tubes ill extend through the crankcase housing and into the oil pan and are positioned above the grooves ldd in the connecting rods so that the fluid within the oil pan may fall within the longitudinal groove it@ and now into the lubricating bores is@ and lid.
The operation of my device is as follows:
When rotation is imparted to the countershatt 35 the crankshaft 23 will be rotated through the endless chain i2 and as the eocentrics fit, ed and 5t revolve, the connecting rods ed, 55 and be will cause the crossheads 5|, 52 and 53 to reciprocate within the cylinders t3, tl and t5. The reciproca tory motion of the crossheads will in turn be transmitted to the pistons BQ, el and Q2 to create a suction within the transverse pump cylinders 83, e0 and d5, and to draw the uid from the inlet tube b5 thereof into the pump chambers intermediate of the valve seats i3 and l5. As the pistons 9b, @l and @d move forwardly in the pump cylinders, the fluid therein willbe disl charged through the outlet port 8i. It will be noted that the eccentrics are arranged on the crankshaft so that constant pumping action will be maintained at all times, and it will be seen that the entire device is formed of metal plates and tubes bolted and welded together in a compact structure that is at once light in weight and durable in construction.
It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred embodiment of the same, and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the appended claim.
Having thus described my invention, I claim:
In a pump construction; a tubular crankcase; laterally extending, horizontally aligned tubular cylinders welded to and communicating with the crankcase, a rectangular sheet metal frame encompassing the said cylinders and with the rearward edge thereof contacting the crankcase, a plate extending laterally from the crankcase in superimposed relation to the cylinders, the forward margin of the plate curving downwardly to abuttingly engage the forward edge of the said frame and with the end margins thereof bent downwardly to engage the crankcase and frame to define a fluid tight enclosure, which enclosure communicates with each of the cylinders through spaced portsextending through the frame and cylinder walls and with the crankcase through ports extending through the crankcase wall, said plates and tubular members being fabricated from structural shapes welded together to define a. light, compact and durable structure.
