Description
Sept. 30, 1930. l. L. SHEPHERD PUMP Filed Aug. 30, 1929 I Patented Sept. 30, 193@ Application ined August 3o, deze. seal No. 389,472.
This invention relates to small pumps such as bilge pumps for use in boats and the like, one object being to provide a pump that is cheap to manufacture and which util- 5 izes an all-metal valve, seat, and plunger, it being possible readily to assemble the parts and to separate them for the purpose of making repairs and replacements.
With the foregoing and other objects in i@ view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that i5 changes in the precise embodiment of the invention disclosed may be made within the scope of what is claimed without departing from the spirit of the invention. In the accompanying drawing the pre- 2@ ferred form of the invention has been shown.
In said drawing,
Figure 1 is a longitudinal section through the pump, two positions of the plunger members and valve being indicated by broken and a5 full lines respectively. r`
Figure 2 is an enlarged section on line 2-2, Figure l.
Figure 3 is a side elevation of the plunger, the adjacent portion of the casing being 3c shown in section.
Figure L1 is an enlarged section on line 4-4, Figure 1.
Referring to the figures by characters of reference, 1 designates a pump cylinder or 35 casing made up of seamless metal tubing cut to a desired length and formed with an outlet spout 2 near the upper end thereof. The upper end of this tubing is adapted to be closed by a lid 3 seated tightly therein and 40 held thereto in any manner desired. `The lower end of the tubing has a metal screen 4i seated therein.
Securely mounted in the casing or cylinder 1 near the screen i is a ring 5 providing a tapered seat 6. This ring has a guide and retaining bail 7 seated therein and extending thereover and slidably' mounted on the end portion of the bail is a metal plate 8 providedwith a tapered disk 9 secured thereto 50 in any manner desired. This disk and plate constitutea valve, diskl 9 being adapt; ed toV engage the seat 6. The upward movement-of the valveis restricted bythe bail 7`. Mounted forre'ciprocation in theA head 3 is' a rod 10 the Vouter end of whichV is' formed with a ,suitable handleil., The inner end ,of the rod has ap'ivot pijn' 12'4 extended dia;- metrically therethromgli'` and" mounted on this pin are ears 13 extendingfronr segmental metal flaps 14., VThe rodV 1Q is extended between theseiia'ps andeach flapis preferL ably Vforifnedwith two earfslthat lap-and are disposed adjacent to the ears ofthe opposed flaps. j i Y n The flaps 14e, when in alinement asshow byfull flinesin Figures land 2, form a s'ub-y stan'tially circular' plunger the` peripheral portion ofwhich isladapted to.travel"clos`e` to the wall ofthe casing'or' cylinder 1. Each fiap'lias an arcuate flange 15 depending there- 'i from .and when the flaps 14e are flush as shown in Figure, these flanges will abut at their ends. Thus the flaps are prevented from swinging downwardly relative to each other after they have been brought into the same plane.
In practice the rod is reciprocated as ordinarily so as to cause the flaps to travel'downwardly and upwardly within the cylindrical l casing 1. Each time the flaps are pulled upwardly away fromthe ring 5 they will act to lift fiuid away from the ring and, by suction, to open the valve formed of the plate and Vdisk 9. When the rod is moved in the opposite direction the flaps 14 will swing upwardly toward each other as indicated by broken lines, thereby allowing fluid to flow freely past the flaps.
It will be seen that a pump such as described can be made entirely of metal and will be capable of withstanding very rough handling.
What is claimed is:
1. A pump of the class described including a tubular casing having an inlet at one end and an outlet, a check valve seated adjacent the inlet, aV rod mounted for reciprocation within. the casing, opposed segmental flaps pivotally connected to the rod and adapted to swing upwardly and downwardly relative thereto and to each other, and means carried by the iaps and cooperating with each other and with the rod for limiting the downward movement of the flaps, said means and the pivotal connection between the rod and aps constituting the sole support for the flaps when closed. Y
2. A pump of the class described including a tubular casing having an inlet at one end and an outlet, a check valve seated adjacent the inlet, a rod mounted for reciprocation within the casing, opposed segmental flaps pivotally connected to the rod and adapted to swing upwardly and downwardly relative thereto and to each other, and means carried by the flap and cooperating with each other and with the rod for limiting the downward movement of the flaps, said means includingarcuate flanges Carried by the respective aps and movable together at their ends when the flaps are flush with each other, said laps being unsupported at their free edges when closed.
3. In a pump the combination with a valved cylindrical casing, of a rod mounted for reciprocation in the casing, opposed segmental iaps pivotally connected to the rod and embracing the rod, and means depending from the flaps and cooperating with the rod and with each other for limiting the downward movement of the flaps.
In testimony that I claim the foregoing as my own, I have hereto axed my signature.
