Similar characters of reference designate like parts throughout the different views of the drawings.

The embodiment of my invention shown in the drawings comprises a container or reservoir (designated in a general way by C) preferably shallow and of circular shape, that is it is of greater diameter than length, consisting of a pair of sections 21, 22 (Figure 4:) to have mating connection as a cover and a receptacle, the one section 21 being arranged with concentric depressed portions 23, 24 in the end to provide an annular rounded or beaded portion 25 and an annular bead 26 within the bead 25 to serve as reinforcing ribs to add rigidity to the structure and lessen the possibility of dent ing should the container be dropped. The section 21 engages over the section 22 to abut a peripheral bead 27 as shown in Figure 2 and limit the connecting movement of the sections, the sections being connected in such position in a suitable manner as by soldering or otherwise. The section 22 has a depressed portion 28 of partially circular formextending transversely and axially thereof with an opening 29 in such depressed portion axially of the container to constitute the outlet of the container. The section 21 has a perforation 30 to constitute the filler opening for the container having a screw threaded flanged member 31 for the application of a closure plug 32.

To connect the outlet opening 29 with the liquid in the container in the lowermost portion in all positions thereof an intake is provided for said outlet arranged to assume a position by gravity'to position an inlet to the intake near the side portion and end of the container which is lowermost. This intake comprises a pair of rigid tubes 33, 33, the tube 33 being carried by a sleeve 34 in liquid connection with an enlargement 35 of said sleeve, said sleeve being rotatably mounted on a stud 36 supported axially of the container with a port or ports 37 in the lateral wall thereof in communication with the enlargement 35 of the bore of the sleeve forming an annular chamber around said stud, said bore leading to a passage 38 in the stud having an outlet at the end in the opening 29 of the container (Figures 2 and 18). The tube carrying sleeve 34 is confined between the end wall of the container section 21 and a collar 39 fixed on the stud and to prevent undue metal to metal contact felt washers 10 are interposed between the ends of the sleeve and the container wall 21 and collar 39. The tubular section 33' is coupled in fluid connection with the tubular section 33 and to have universal movement relative thereto. For this purpose a hollow plug or casing 41, shown of triangular shape in cross section, is couple'd in liquid connection with the tube 33 by a member 42 fixed to the end of said tube and upon which the casing 41 is mounted as at 43 to rotate on an axis parallel with the axis of rotation of the tube carrying sleeve 34. The tube 33 is coupled in liquid connection with the casing 4:1 by a member 4% fixed to the end of the tube 33' and rotatably mounted in the casing, as at 45, to rotate 011 an axis transverse to the axis of rotation of the casing on the coupling member 42. The tube 33 extends to adjacent the side of the reservoir with the end open and is adapted to position such inlet by gravity near the side of the container below the axis of the intake supporting stu'd 36, such movement being facilitated by a Weight 4-6 fixed to the section of the intake 33. By the arrangement of the universal coupling of the intake sections the tube 33 is also adapted to assume a posireac es tion by gravity to position the inlet thereto near the end of the container. which is lowermost. By this arrangement theoutlet of the container is maintained in communication with or immersed in the :liquid in the lowermost part of the container in all positionsthereof and out of communication with the fluid pressure should fluid pressure be utilized inthe container for expelling the liquid therefrom, and said intake may be utilized as an intake to the pumping mechanism to eject the liquid from the container to maintain the pumping mecha nism in communication with the liquid in the lowermost part of the container in all positions thereof. Furthermore, by this arrangementiof intake should the Wall of the container be dented, as shown for instance in dotted lines at 47 in Figure 1,:suel1 dent would not obstruct the free. movement of the intake in the container.

To eject the liquid from the container pumping mechanism is provided mounted on the exterior-of the containeinor casing in the recessed portion 28 i to extend transversely of the ax'is of the containerand fixedin positionas-by soldering as-shonin at 48, and a plate 49 fixed to the containeinat theouter side of the pumping mechanism to serve as a protection therefor andfora further purpose hereinatter set forth, This pumping mechanism comprises .a piston chamber or cylinder 50 having a perforated plug 51 :at one end and a plug 52 at theloppositeend having a recess .With a. discharge nozzle 52 secured therein to form a. chamber .50, a port 53 in line with the orifice oi itheudischarge nozzle communicating with the ad jacentend of the pump cylinder. The pump cylinder has inlet ports 54, 55 .at opposite ends, the port 55 communicating with the cylinder through a passage 56 formed by a recess in the outer wall oi the plug.52 and the cylinder. These ports are:connected to the outlet .29 ofthe container and through the intake wit-lithe liquid'in thecontainer by a tube 57 to lie contiguous to the pump cylinder and having ports in communication with. the inlet ports of the eylil'ider by turning the metal about the wall of the inlet ports to the cylinder over the edgeof the Wall of the ports-in the tube, as Shown at 58 in Fig:

- ure 20. The tube 57 has an inlet port.59

connected to the outlet 29 of the container through vapassage 60 formed by a dished plate til having an opening iforthe engage fixed to the ,outeimend. The flow oi liquid from the container to the cylinder thrmigh the tube 57 is controlled by suction valves through the reciprocation of :the piston. These valves may be of any .uell known structure and as shown in. Figures 3, 5, 6, 7, andQWcomprise a valve head ('55 carried by a stem 66 (Figure .9) slidably mounted in a tubular ,projectionfi'r' of a closure plug 68 for the =Q11Cl$z0flt1l6 tube. These valves 00- operate with valve seat-s 69interposed in the tube between the inlet and outlet ports thereof and in the present instance are arranged by restricting the passage in the tube by annularly depressing the Wall of the tube asclearly showninthe drau'in The liquid discharged from the pinup cylinder in back of the piston through a port '70 and a registering port in a tube 71 and through said tube through registering ports in the cy linder, tube and plug 52, as shown at 72, communicating with the ichamher in the plug 52 and from said chamber through the discharge nozzle. The dis chargingnf the liquid from saidcndof the cylinder is controlled by a valve 73 constructed similarly toithe suction valves, and slidably carried by a plug 74 .to close one end oi'thetube, the opposite .end of the tube being closed by a plug 75.

The liquid from the pump cylinder in front of the piston .is discharged into the chamber of ,the plug through a valve 76 .(Figure 11) in said chan'lbensaid valve having a tubular portion 77 slidahly engaging in said port with the bore of the tubular port-ion opeljling into the cylinder, and said bore beingiin communication .urith the chamber througha port or ports 78 in the lat-- eral \vallv of thetubularportion of the alve. This .valve is normally urged to position with an annular enlargement 79.0tthc valve to co-operate with a valve seat at the port 53 and avith the lateral ports 78 in the valve eloscdbydhe wall of the port 53by a spring 80 (Figure .5). This .valve also serves to close the-.dischargeori fice in thenozzle when the piston is initsinnerlnost position to preventjleakage of the hqiudvfroln the container through thepump-and nozzle when the. de- V1CG.lS110ti11.USB Flgure 7). For thispurpose theend of-the valve opposite to the tu? bular portion has a reduced portion with a tapered lend assho vn at '81 to cooperate aviththe valve seat formed atthe inner end of the discharge orifice of the nozzle. As the piston 1 is moved to its innermost position :it will-yicldingly engagethe valve To through a spring 81 carried in an enlarged portion of the bore of the tubular portion of the valveand interposed between the valve and piston and thereby move the valve 76 Oil llfl

against the action of the spring as clearly into tube 71 unseating valve 73 and disshown in Figure 7 In Figure 19 I have shown a modified form of the valves to control the ingress of the liquid to and the egress of the liquid from the piston chamber, said valve consisting of a ball 82 normally yieldingly urged to a seat by a spring 83.

To look the piston in its innermost position with the valve 7 6 closing the discharge orifice in the nozzle a collar 84 (Figures 14: and 15) is secured to the piston, said collar having a segmental lateral flange 85 which is adapted to engage beneath a locking member 86 carried at the end of the pmnping mechanism, and shown as mounted upon the closure plug for the tube 71 by a screw 87. This collar 84 has an enlarged portion with packing therein to co-operate with the plug 51, as shown at 88, to seal the piston rod when the device is not in use. The locking member 85 is so arranged on the piston rod that when it is in looking position the handle of the rod will extend in a plane substantially with the circumferential wall of the container so as not to project beyond I the end thereof.

In operation as the piston is moved outward, as indicated by the arrow in Figure 5, the suction valve 65 at the end of the tube 57 adjacent the discharge nozzle is unseated drawing liquid from the container through the intake means to the piston cylinder in front of the piston through port and passage 56. As the piston is moved into the cylinder inthe direction indicated by the arrow in Figure 6 the suction valve at the end of the tube 57 adjacent the piston operating handle will be unseated and liquid drawn to the piston cylinder in back of the piston, the suction of the piston also operating to seat the valve 7 3. During this movement of the piston the liquid previously drawn into the cylinder in front of the piston operates to maintain the valve 65 controlling the flow of liquid to the front of the piston closed, the pressure of the liquid upon the valve 76 moving said valve against the action of spring 80 until the lateral ports 7 8 are uncovered and in communication with the chamber in the plug 52, the liquid being discharged through the tubular portion 77 of such valve and'the lateral ports 78 into the chamber of plug 52 and out through the discharge orifice of the nozzle. On the successive reversed movement of the piston the operation of drawing the liquid to in front of the piston is repeated, the outlet port 53 from in front of the piston being closed by the valve 76 through the influence of the spring 80, the pressure of the liquidin back of the piston seating the alve 65 in the tube 57 at the piston operating handle end, the liquid being discharged through the registering ports charging the liquid from said tube through ports 72, into the chamber of the plug 52 and out through the discharge orifice of the nozzle, and such operations are repeated during the reciprocation of the piston.

The protect-ing plate 49 for the pumping mechanism is also arranged to releasably engage a support to support the device therefrom. For this purpose the plate is arranged as a slide by pressing the metal of the plate, as shown at 90 in Figures 3, 15 and 17, to form ribs 91 at opposite side portions to extend longitudinally'of the pump and converging from the piston operating handle end of the pump to the discharge nozzle end as clearly shown in Figure 3, said plate thereby serving as a hanger to co-operate with a supporting bracket in the form of a plate 92 (Figures 15, 17 and 18) bent to form longitudinal recesses 93 to correspond to the shape and for the engagement of the ribs 91 and adapted to be secured to a suitable support such as a wall, by screws passing through a lateral projecting portion of the bracket as shown at 94. To prevent accidental displacement of the device in the support 92 means are provided to lock the device in the support which locking means automatically locks the device in the support as it is placed therein and is releasable by a predetermined force applied to the device to remove it from the support. This locking means comprises a spring detent or latch 99 fixed at one end to the outer side of the supporting plate 92 with the free end arranged to pass through an opening in the supporting plate and engaging in and with the walls of an opening inthe plate 49, as clearly shown at 100 in Figures 15 and 17.

To permit the entrance of air into the container as the liquid is discharged therefrom by the pump to displace the discharged liquid and prevent the creation of a vacuum in the container an air vent is provided. This vent in the present instance is arranged in the closure plug 32 for the filler opening, a transverse port 95 (Figure 16) in the portion of such closure arranged to be at the exterior of the container when the closure is applied to the filler opening communicates with a port 96 leading into the container, said latter port being normally closed by a valve 97 in a recess in the closure plug and urged to position to close the port 96 by a spring 98 confined between said valve and a collar threaded into the recessed portion of the closure, this valve being adapted to be unseated by a reduction of pressure in the container,

In assembling the pump and container the pump mechanism is first assembled when the tubular stud 36 is connected to the pump by means of the dished plate 61. The

pump is then connected to the container or caslng section 22 by inserting the stud? 36 connected to the pump through the opening 29 connected thereto in liquid tight connection by soldering around the edges of the openin 29. The intake is then assembled upon the tubular stud 36 when the container sections are connected and secured together as by soldering with the reduced and shouldered end of thestud 36 engaging in an axialopening in the casing section 21 and fixed therein by riveting said reduced end at theou-ter side of the casing section 21 and soldering.

In Figi ire 21 I have shown a modified structure of nozzle toconnect the orifice of the discharge nozzle with the chamber in the casing 52 to permit of the flow of the liquid from such chamber and the nozzle orifice without obstruction by the valve spring 80, and a n'iodification of the valve mechanism to'controlthe flow of liquid from the tube 57to the forward end of the pump cylinder and the discharge of the liquid from the opposite end of the cylinder through tube 71 to thechamber in the casing. 52. To permitof the free. flow ofliquid unobstructed: by the spring 80 from thecasing. chamber to the orifice of the nozzle the one end of'the spring is seated upon an annular seat of a portion of thenozzle extending in tothe casing chamber, asshown. at 52", said projecting nozzle portion having radial slots 52 cut therethrough to maintain the casing chamber open to an enlargement of the nozzle orifice permitting the flow of the liquid from the casing. chamber to the nozzle orifice outsidev of the spring without the necessity ofpassing through. the spring as is the'ease in a structure as shown. in Figure 3. To connect the tube 57 with the piston cylinder in front of the piston. and to connect the tube 71 with the chamber of the casing 52 plugs 102 and 102 are secured in openings in the piston cylinder toextend laterally therefrom and from the casing, said plugs having angular plugstherein in communication with the recess 76 and. the port 72 in the casing 52 and to which ports of the plugs the tubes 57 and71 are connected as clearly shown. To control the connection of the tube 57 with therecess 76 communicating with the piston cylinder in front of the piston a ball valve 82 is provided which is adapted to co-operate with a valve seat. arranged at the end of the port in the plug in communication with the recess 76. It Will be noted that when the liquid is being dischargedfrom in front of the piston 'the pressure of the liquid on the valve through the recess 76 will operate to seat the valve 82 and shut off the piston cylinder' from the tube 57, and that such ball will be readily unseated by the suction of the piston as the latter is movedoutward from the piston cylinder to permit the drawing of liquid to in front of the piston through the tube 57, there being suflicient space between the seat for the ball 82 and the recess 7 6 to permit of the flow of the liquid past the ball to the recess 7 6 and the piston cylinder. The discharge of the liquid from back of the piston through the tube 71 to the chamber in the casing is controlled by a ball valve 82 adapted to co-operate with a valve seat formed at the connection of the bore of the plug 102 to control the connection of the tube 71 with the chamber of the casing 52. To connect the tube 71 with the casing chamber when the liquid is being discharged from the piston cylinder in back of the piston and to permit the ball valve 82* to be unseated and maintain open communication between the bore of the plug 102 and the port 7201: casing 52, an elongated recess 72 is provided in the outer wal lof the casing to intersectthe port 72. This recess will permit the ball to be sufliciently moved from its seat by the pressure of the liquid coming through tube 71 to permit the flow of liquid past the ball through the recess 7 2 and port 72 to the casing chamber. The discharge of the liquid to the casing chamber from in front of the piston is. controlled through the valve .76, which is constructed and operates in a manner as and for the purpose hereinbefore set forth, the pressure of such liquid as it is discharged into the casing chamber, due to the restricted area of the discharge orifice of the nozzle combined with the suction of the piston during this movement of the same, operating to maintain the valve 62 seated shutting off communication between the casing chamber and the tube 71. The valve 76 is also arranged with the reduced portion 81 to cooperate withthe valve seat at the inner end of the discharge orifice of the nozzle when the piston is in its innermostv position to. close such orifice.

The combination of a cylindrical liquid carrying container of greater diameter than length and having an outlet axially thereof; and an intake from the container to said outlet comprising a rigid tube, means to support said tube to rotate about the axis of the container and connect the same to the outlet, a second rigid tube; and means to connect said latter tube at one end in fluid connection with the first tube and to have universal movement about said connection relative to the first tube with the opposite end open and adapted to assume a position near the side and end of the container which is lowermost in all positions of the latter.

19. The combination of a liquid carrying container having an outlet; a piston chamber having a discharge outlet at one end mounted upon the exterior of the container; a piston; a rod to reciprocate the piston extending from the end of the piston chamber opposite the outlet; suction inlets to opposite ends of the piston chamber connected with the outlet of the container; a valve controlled outlet from one end of the chamber connected to the discharge outlet; an

outlet from the opposite end of the chamber connected to the discharge outlet; and a valve to control the discharge of liquid from said outlet, said valve being operable when the piston is in its innermost position 7 to close the discharge outlet for the purpose specified.

20. The combination of a liquid carrying container having an out-let; a piston cylinder having a discharge outlet mounted upon the exterior of the cylinder and having inlet ports to opposite ends thereof; a reciprocable piston in the cylinder; a tube connected at opposite ends with the inlets of the piston cylinder and having a connection between said inlet connections with the out let of the container, valves to control the connection of said tube with the inlets of the piston cylinder; an outlet from one end or the cylinder; a tube to connect said outlet with the discharge outlet of the cylinder; a valve to control said connection of the cylinder with the discharge out-let; an outlet from the opposite end of the cylinder connected to the discharge outlet; and a valve to control said latter connection of the cylinder with the discharge outlet operable when the piston is in its innermost position to close the discharge outlet.
