To all whom it may concern:
Be it known that I, ARTHUR EGGLETON Wonsrnn, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Pumps, of which the following is a specification.
My invention relates to improvements in pumps, and the object of my invention is to devise a pump of simple construction with the minimum of parts capable of being manufactured at a low cost and which is highly efficient in operation and adaptable for use as a vacuum pump or for pumping air, gas, or any fluid material.
I attain this object by the construction illustrated-in the accompanying drawings in whichi Figure 1 is a longitudinal sectional elevation of my pump.
Fig. 2 is a plan view.
Fig. 3 is a plan view of the piston.
at is a plan view of the suction valve guide bar.
Similar figures of reference indicate similar parts throughout the several views.
The pump is constructed as shown in Fig. 1, in which 1 indicates the pump barrel, internally threaded at its lower end to receive the correspondingly threaded partition member 2, which member closes the lower end of the barrel and is provided with a central bore 3 by means of which comunication is established between the pump barrel and a lower receiving chamber 4, which chamber is secured concentrically to the lower end of the barrel by any suitable means, such as shown at 5,in Fig. 1. 6 indicates the suction pipe fitted into the end of the'chamber 4-. The lower face of the partition 2 is cut out to form a concave recess 7 while on its upper face is formed, concentric with thebore 3, a concave seat 8, with which seat co-acts a convex faced suction valve 9, this valve being provided-witha central depending stem 26 to lower end of which is secured a transverse guide bar 10, formed as shown in Figs. 1 and 4:, whereby it, the valve 9, returned to its seat after each of its lifting movements is completed. The ends of the bar it are rounded to conform to the shape of the recess 7, as it enters therein on each upward movement of the valve, as indicated by the dotted lines in-Fig. 1, and. the

11 indicates the pump piston, which is provided with ,one or more ports, as indicated by the numerals l2 and 11.3, its upper surface being formed partly convex, as at let, and partly as a mitered seating, as at 15. To the piston is secured a piston rod 16, the upper end of which is connected to the jaws 17' of a suitable connecting rod 18, and below the connection and adjacent thereto the piston rod is provided with a collar 19, between which collar and the pieton 11 and vertically movable on the rod 16 is a lift valve 20 adapted to co-act with the piston to open and close the ports thereof. This valve 20 is mitered on its lower face, as at 2]., to correspond with the seat 15 of the piston, while the remainder of its lower surface is formed concave, as at 22, to correspond with the convex surface 15 of the piston, but it will be noted, referring to Fig. 1, that the construction of the valve is such that when it is in its lowest position resting on the seat 15, the concave face 22 of the valve is spaced apart from the convex face of the piston, as indicated by the numeral 23, and while this space 23 may be made parallel throughout, it is preferabl to arrange for the space to be wider toward its outer er ge than at its center, the purpose of the space 23 being to prevent the accumulation of dirt and foreign matter between the concave valve face and the convex face of lhe piston andto permit of the continuous washing and cleaning of the surfaces by the fluid passing through the ports 12 and 13 during the operation of the pump.
2% indicates the connecting rod guides.
The operation of the device is similar to that of reciprocating piston or plunger pumps. 0n the upstroke of the piston 11 the suction valve 9 is raised, allowing the fluid to flow from the receiving chamber through the bore 3 into the barrel 1, the valve being returned to its seat by the weight of the bar 10 and it will be seen that as the bore 3 is of greater diameter than the valve stem 2-6 the valve drops freely and seats itself under any conditions. On the downstroke of the piston the fluid is forced up throiw'h the ports 12 and 13 to pass out througn the. discharge outlet, the
valve 20 being then raised, falling into its seat, however, on the next upstroke of the piston, the space 23 then formed between the piston and the valve preventing the accumulation of foreign matter and keeping the surfaces always clean.
Vhat I claim as my invention is 1. In a pump, a ported pistonhaving its inner upper surface formed convex and terminating at its outer edge in a valve seat, and a discharge valve for the piston ports adapted to co-act with said seat,said valve having a concave face complementary to the convex piston face and cooperative therewith whereby a liquid cushion is formed between th faces as the valve closes.
2. For use in a device of the class de scribed, a ported piston having its inner upper surface formed convex and terminating at its outer edge in a initered valve seating, and a discharge valve for the piston ports, having a concave face and a mitered neeaol i seating co-acting respectively with the convex face and initered seating of the piston, the concave and convex surfaces being spaced apart when the valve is closed, whereby a liquid cushion is formed between the surfaces as the valve closes.
3. For use in a device of the class dc scribed, a ported piston having, its inner upper surface formed convex and terminating at its outer edg in a mitered valve seating, and a discharge valve for the piston ports having a concave face and a mitered seating co-acting respectively with the convex face and initered seating of the piston, the concave and convex surfaces being spaced apart when the val e is closed whereby a liquid cushion is formed between the surfaces as the valve closes, the said space being wider toward its outer edges than at its center.
