LIQUID-PROJECTNG DEVICE.

Application filed July 24, 1915. Serial No. 41,650.

" To all i071 om t man] concern:

Be it known that I, ALBERT V. SAMMIs, a citizen of the United States, and resident of Huntington, in the county of Suffolk and State of New York, have invented certain .ew and useful Improvements in Liquidrejecting Devices, of which the following a specification.

My invention relates to devices for eX-.

peiling and project-ing liquids contained in receptacles, and particularly to devices by means of which the liquid .will be 'expelled from the vreceptacle, forcibly so as to be projected a considerable distance, as may be ,fesirable in the casel of portable lire eX- tingnishers containing a lire-extinguishing liquid. rll`he purpose of my invention is to provide a device of this character which will be simple and effective in operation, and by means of which I am enabled to expel and vproject the liquid in aA practically ,con-

Iii

tinuous stream or jet.

rlhree embodiments of my invention are shown in the accompanying drawings in which- Figs. 1 and 2 are vertical sections, looking in the same direction, and taken in the main through the center of the receptacle, but showing most of the interior parts vin face view; Fig. 1 differs from Fig. 2 by showing the upper intake tube broken off and in a different position, also by showing the handle in operating position, while Fig. 2 shows the handle folded down and in section; the airalve is omit-ted from Fig. 1, butis shown in section iii Fig. 2; the guides 57, 58 appearing in Fig. 2 are omitted from Fig. 17 which sh ws the parts 57, 58 in section, as well as the nozzle 25'; Fig. 3 is substantially a cen-Y tral section of the. apparatus, taken at right angles to the direction in which Fig..1 faces, and showing all the interior parts in face view, with' the exception of the guides 57, 58, which appear in section. Fig. a is a horizontal section taken on line 4 4 of A' 2; Fig. 5 is a partial vert-ical'section through pump cylinder 2st.

certain parts in a different position; Fig. 12V

is a perspective view of one of the valve members shown in Figs. 6 and 8 (these valve members havingbeen vomitted from Fig. 11 for the sake of clearness) Fig. 13 is a detail vertical section showing certain valves; F ig. 1a is a horizontal section on line lat-1a of Fig. 13; Fig. 15 is a detail vertical section of another valve; Fig. 152L is a horizontal section on line 15fL 15a of Fig. 15; Fig. 1G is a top view showing the device hung against a wall; Fig. 17 is an enlarged view similar to Fig. 6, but with certain parts in the position shown in Figs. 10 and 11; this view-also illustrates a modification of the automatic air inlet; Figs. 18 and 19 are a vertical and a horizontal'section respectively of a modification of my inventi`on,F ig. 19 being taken online'19-19 of Fig. 18.

In the said drawings, 2O indicates the cylindrical wall of a receptacle whose ends are closed by heads 21 and 22. Through the head 21, at a point as near its periphery as possible, extends, rigidly connected therevwith, a casing 23 to the lower portion of which is secured rigidly the upper end of a rllhe lower end of said pump cylinderfis closed by a plug 25 (Fig. 5), whose main portion rests on theliead of the receptacle, while a lateral extension projects through said head and is perforated to form a nozzle 25 through which the fluid vcontained in the receptacle is expelled. The

upper .portion `of the'casing 23 receives another plug' 26 held against longitudinal movement by a shoulder on said casing and by an annular flange 27 on a cap 27, but is capable of turning around the axis of the pump cylinder. A vwasher 27 is interposed between the flange 27 portion of the plug 26 as well as the upper end ofthe casing 23, in order to insure a tight joint. The casing 23 and cap 27 are secured to the head 21 by screws 23', a washer 21 being preferably interposed between' the head and the said cap. The head is formed with a boss 2l having fiat upper and the corresponding f plug 26.

and lower surfaces. Through an aXial hole in the plug 26 extends loosely a piston rod 28 carrying at its lower end the piston 29 adapted to reciprocate in the pump cylinder. The upper Kend of the piston rod 28 is screwed into, or otherwise rigidly secured to, a head 8O to which is pivotally connected, by a pin 32., the shank 32 of a handle 32 by means of which Vthe pump is operated. A suitable packing held in place by a gland insures a tight joint between the piston rod 28 and the plug 26.

rl`he plug 26 is formed with two segmental compartments 26, 26 communicating with each other by channels '26* (Fig. Sa) which form` a chamber `or passage with said compartments. Each of these segmental compartments Acfmtains arti-shaped valve (Fig. l2) capable of a slight longitudinal*movement to cause its transverse central member to luncover a port 26am the lower portion of the plug 26, through whichlports the passage 26', 26, 26* ray at times communicate with the chamber of the pump cylinder between the piston 29 and theplug 26. The vertical edges of the parallel longitudinal en'd members of the valves 35 vare in guiding engagement with the inner wall ot the casing 23 and with vertical surfaces 26 on the inner portion of the plug Y26. These longitudinal members also limit the opening movement of the valve. vrBetween the segmental'compartments v26', 26 the plug 26 vis provided with suitable recesses to receive scaling plugs S6 whichfmay be pressed outward by springs 3,7, 37 (Fig, l1) or they maybe simply made of elastic materialsuch as cork, Vin 'which case no separate springs are required (Fig. 8). These plugs 36,36 are adapted to close the ends of tubes38, 39 lead? ing to diamctrically opposite points ot the said chamber of the plug 26. The saidtubes vextend to points near the bottom of the receptacle 20, the tube 3S, which acts as an outlet tubo, beingconnected withthe nozzle 25, while the tube'lf) conununicates with the lower chamber of the pump cylinder at its bottom. The tube 39 consists ot two parts between which is interposedza-valve casing 40 containing a'checlr valve the transverse' central member v40 of which controls the passage of the fluid by opening or closing the port oi' the valve casing, while the longitudinal members 40, ofwhichthere are three in the particular construction shown, serve to guide the valve: in its movement toward and from its seat, and also to Vlimit the opening movement of the valve.

From a point adjacent the lower end of the tube 39, another tube,v4l, loads from the lowermost portion of the'pump cylinderfto a point slightly below thcvlower face of the rlhis tube V4l also consists of two parts connected by a valve casing 42, which latter contains two chan'ibers 42, 42 communicating with each other by a passage 42f. The ends of this passage form ports adapted to be closed by the central transverse member 43 or 44 of suction valves adapted to become seated on said ports, said valves also having longitudinal members 43', 44 respectively (four as shown) which not only guide the valve in its opening or closing movement, but also limit the extent of its opening movement. From the passage .42# a short tube 45 leads to a similar passage 46* of a valve casing 46 having'two rchambers 46, 46 and containing two ballvalves 47, 47 with a guide rod 48 connecting them. The valve chambers 46, 46 communicate with tubes 49, respectively which extend inv oppositeldirections fromY the casing 46 lengthwise ci the receptacle, the free end of the tube 49 reachingtoa point adjacentthe head 2l of the receptacle, while thefree end of the tube 50reaches toa point adjacent the other head 22 ofv the receptacle. The connection betweenA the tubes 49, 50 and the valve casing 46 is nota rigid one, Vbut loose and preferably universal, so as to allow the free ends ofthe vtubes 49, 50 to assume a lower-most position adjacentto ythe heads of the receptacle. These tubes, which arerigid, have their attached endsl extended into or through ball-shaped'members 49', 50 respectively, whichare held loosely within the valve chambers 46 and 46 by caps 5l, 52 respectively, recessed to fit the said ballshaped members 49, 50. ln order to prevent any longitudinal movement of theballshaped members 49', 50 with their respective tubes 49, 50, andto insure a tight joint, perforateddislrs 53, v54 are providedwithin the valve chambers; these disks have recessed seats for the ball-shaped members andare pressedV against the vlatter by springs 55, 56 respectively. This will allow the ball-shaped members a certain freedom of `movement around their centers, yet prevent any'leakage past their outer surfaces. The tubes 49, 50-are preferably weighted at or near their tree ends, as shown at 49, 50 so as yto make sure that these tree ends or intakes, or at least one oi" them,-will always assumo a -position `lowermost in the'receptacle, irrespective of thevposition inwhich thereceptacle is being held and operated. In order to insurethese swinging ends of the -tubes 49, 5() against getting calught and wedged between the other tubes within the receptacle, lf provide guides 57, 58 (Figs. 2, 3 and 4) secured to the pump cylinder by flangesv 5?', 58. These guidesA are arranged in'sucha way that the'tubes 49, 50 willrslide on themto the lowest point in the receptacle and cannot become caught in `other parts of the device. This of course applies only to cases wherethe receptacle is held andoperated in sucha position' that the pump cylinder and connected tubes will be lll) located below vthe remaining space ofthe receptacle.` In all other positions the free ends of the'tubest), 50, or at least one of them, will slide along the cylindrical wall 20 of the receptacle so as to bring the inlet of the active tube to the lowermost point of the receptacle. l

In the exian'iple of my invention illustrated in the drawings, I have shown the heads of the receptacle as being of spherical curvature, with the centers of curvature lying in the axis yof the receptacle. rI`his gives the receptacle `a. symmetrical shape and appearance. In this case, the points about which the intake tubes swing, that is the centers of the ball-sha eed members 49, 5i', will also lie in the axis of Ithe rec ptacle. However, the symmetrical arrangement is not essential to my inventiom'the above advantage being present as long as theheads of the receptacle are spherically curved, with the centers of the curvature coinciding with the centers of the swinging movement of the respective intake tubes, so that the intake ends of the tubes 49, 50 will always be at the same distance from the heads of the receptacle (as near to them as practicable) lin whatever position the receptacle may be held.

rIhe head or top 2l of the receptacle is provided with a filling opening normally closed by a cap 59, which, in the preferred form of my invention, also contains an automatic air valve 59 ofv any approved con struction, through wiiieh air will be drawn into the receptacle whenever Vliquid isr eX- pelled therefrom. The cap 59 is shown as a wing screw adapted to receive between its two wings the shank 32 of the folding hanf dle 32, when the apparatus is not being used. The wings may be provided with suitable holes so that the handle can be'tied to the wing' screw and'sealed thereto if desired. In order to bring the handle into the operative position, it will be swung on its pivot, the pin 327, until its vshank is in alignment with the head 30. A sleeve 60 surrounding the shank 32 a spring (il over the forked upper portion of the head 30 and will firmly lock the han-V dle to said head. After the apparatus Vhas been used, the sleeve 60 maybe pushed up against the tension of the spring 6l until it clears the upper edge of the head 30, and the handle can then be swung on its pivot until its shank rests on the wing screw 59. l/Vhen folded as in Fig. 2, the handleisless exposed to injury say during shipment thanv when swung into the operating position (Figs. l and). *l i For the purpose of insuring vthe piston and the head 30 against accidental longitup dinal movement, the followingl locking device is provided: rlthe head 30 has at its lower portion two segmental ribs or flanges 30 located diametrically opposite each will then be pushed down by Y other, each flange having at one end an outward `projection or stop 30, as Ashown in 'I Figs. 7, 9 and l0. These flanges, which are preferably slightly beveled on their upper faces at the end opposite to the stop (Fig. 9) are adapted to be engaged from above by stationary segmental flanges 27 formed on the cap 27, on opposite sides thereof. In order to lock the head 30 against longitudinal movement, the handle 32 is pushed in fully to the position shown in Figs. 7 and 9 and is then given a turn of about 900, taking with it the head 30; that is, the handle will be turned until the stops engage the edges 27 `on the flanges 27* (Figs. 10 and 17)'. The head 30 with the piston rod andl piston will thus be securely locked against longitudinal movement. The slightly beveled ends of the flanges 30 will facilitate l the entrance of said flanges between the flanges 27 t and the flanges 27. A felt washer 3l is interposed between the lower face of the head 30 and the upper face of the plug 26, so that in thel locked position the head 30 will be pressed against the flanges 27 f. If it* isy desired to unlock the head 30, the handle 32 will be turned back to the position Figs. 7 and 9, the'l stops 39 preventing the head 30 lfrom being turned too far. The flanges 30'; will then' have cleared the flanges 27* completely, and 'tte pump can be operated readilyv (Figs. G, 7 and 9).

The following device is employed to causev the plug 26 to turn with the head 30 when the latter is in its lowermost position. The valve casing 26 is provided at diametrically opposite points with projections or flanges 26c extending upwardly between the head 30 and the cap 27 (see Figs. 6 and 7) and of such a circumferential extent as to lit be tween the Aflanges 30. Those portions of the radial edges of the flange 30 which are adapted to be engaged by the projections 26C, form seats for said projections to permit longitudinal separation of the handle from the plug while compelling them 'to turnv in unison when said projections are engaged by their seats. Those portions of the flanges 30 which fit under the flanges'2'7f constitute the means for locking the handle against longitudinal movement. Byfturninp;

sage 26', 26, 26:. .lhile I 'have shown in the drawings two plugs 36, 3.6', I desire it to be understood that the action ofthe plug` sealingthe tubev 39 is not material` and that se p vi--I it `would *be suliicient `to 'provide a single plug having -for its office the sealing oit the tube 33. l prefer however to employ two plugs for the following reason "it only'one plug is used, care will have to be Aexercised in assembling the apparatus to have this plug -in the position of 4the plug 36 Vin Fig. 8, since if the plug were by Amistake placed in the position of the plug 36 in Fig. '8, the outlet tube 38 would remain 'unseale'd after the turning ot the head 30 Vinto the position shown vin Fig.l 11. W hen Vhowever two plugs are used, it ldoesnot kmatter how the parts are placed in assembling, since'one or the other of the plugswill be sure to come into the position'sealing the tube 38.

The location ofthe pump and 'its operating :handle to one side 4of the receptacle offers Athe advantage oit affording a Vrelatively large unobstructed chamber iin lwhich the intake tubes 49,50 'may swing (see Figs. 3 and 4). Furthermore, this arrangement enables ine to 4locate the points Yabout whieh the intake 'tubes swing, in the :longitudinal central axis of the receptacle. The ,device for lockingthe handle against longitudinal movement is so arranged that in the locked position (Fig. :10) thehandlelproper 32 will extend transversely, as shown in Fig. 16 (that is to say, the yhandle proper will be perpendicularto a plane containing the axes of the receptacle and ott `the pump). The handle proper will therefore in the locked position-stand so-asito ymake it easyto suspend the device against ya wall saybyfmeans of adouble hook engaging theundersurtace of the handle proper Lateah side'otthe shank'32. li/Vhein'asshown in Fig. 16,the endsl of the handle "properiin the -saidlocked position project beyond fthe'outline of the receptacle, l secure the further Aadvantage of preventing or hindering 4the rolling di' the receptacle it kept Ain a horizontal position in a tool box or the'like.

nstead ot combining Vthe'automatic air inlet with 'the flling 'capf niayladmt the air to the'interiorotthereceptacle through thc 'handle Aand piston rod, as "has Ibeen .shown in Fig. 17. Forthis purposethepiston rod, which in this case must behollow,

communicates with'the outside air through the'head 30'andhas at'its'upp'er end an internal screw thread lG3 adapted to receivea valve seat 64 with-a springspressed valve 65 opening toward the interior of the ,piston rod. `The lower portion of thepiston'rod is likewise screwethreaded internallyzto receive a suitable packing G6 surrounding stationary tube 67,the ylower -end ot Awhich is secured to Vthe plug 25 and communicates with the inner space of the Treceptacle through a Vchannel 25* in said plug. The plug25lis exactly the samelas the'plug 25 shown in the main form of my invention, except torthe provision o-tthechannel 25?.

.the compartment 26 26"toth'e compartment 26', thence'intothe "y "tube 38 y'and vprojected out ot ,the receptacle J.through the narrow /openin'g'in the nozzle nes-:agarre "lhe outward movement oi the piston will exert suction 'in 'the lower chamber ot the pump cylinder and dr w liquid contained in the receptacleV into said `chamber through the tube 4l, chamber 42, passage 42:11, tube 45, passage "46:", one of the chambers V46 or 4G, and its corresponding intake tube 49 or 50. The . valve 47, 47 acting bygravity, .the liquid 'will always be sucked in through 'that one ofthe tubes 50 whose intake is at the lowest level, while the communication of the other tube tothe channel is :closed bythe corresponding valve member 4T `or 47,.so that theV air in the upper part ot' .thefreceptacle can never be sucked into the .pump cylinder. otth'e apparatus being held perfeetly horizontal, both intake tubes 49, 50 will be open at't-he same time to the passage 464i, so that liquid `will be drawn into the ,pump .from 'both tubes, thetfree ends otwhich of course rare both within 'the liquid in such case. 'The valve 43, 43 or 44, 44 of course will be open in the direction 'from whichithe suekingraction is exerted, .and simultaneously therewith,'thevpressure created in the chamberabove the lpiston also tends to keep the -other ' valve 44, 44', or 43, 43 respectively, closed. `When the piston has reached its uppermost position and the space below it thasvbeenentirely filled wit-hiliquid, the return stroke of the piston will i'orce this liquid out :through the tube 39, valve 40 (which will be in theopen position-owing to the ,pressure vexerted from below), finto' "thecompartment 26 formed in the plug` :26. As has" been vdescribed above, V'the un- 5locking-oithe handle.has'brought the l plugs 36, 36 which in-the positionotrest, with theh-andle locked, sealthepentls ofthe- tubes 38 and 39, Vintothe `position shown zintFig..

S, -so that'thesetubes Vvrein Communication :with cach other v:through passage 26', 2G, 2G*l The'liquidwill lthen be forced from through the passages 25. At the same@timeliquidwillbe sucked into the upper-chamber ofthe pump cylinder through one of 'the intake Vtubes 49 'or 50,'the valve casing 46,tube"45,valve casing v,42v andl tube `4l, 'the valve'member w44 duringthis stroke being'pressed on its-seat owing to the ypressure created in the lower partfot fthe cylinder, so: that the liquid =will pass from thetube45 and 'chann'el 142* Ipast'the jvalve member 44:"to vthe chamber 42 ol? the valve casing 42.

At the next outward stroke ot thelpistonq the liquid which now 'fills-the chamber ot In the unlikely event -llll Ll l) the cylinder' between the piston 29 and the plugh 26, will be forced into the passage 26, 26 26* through the openings 26, by lifting the ll-shaped valve members j. Owing to the pressure thus created in the passage 26, 26, 26a: the check valve 40 located in the tube 39 will be closed, so that the liquid will be forced through the tube 38 and ejected through the nozzle 25. During this outward stroke of the pump piston, the lower chamber of the pump cylinder will again be lled as described above, and the operation can be repeated Vas often as desired, or as long as there is any liquid contained in the receptacle. During the inward stroke ot the piston, thevalve members 35 will be pressed down on their seats, so as to close the openings 26a and to prevent any liquid passing through the passage 26, Q6 26* from being sucked into the chamber of t-he pump cylinder between the plug 26 and the piston 29. As the liquid is expelled at each stroke, a corresponding volume of air will of course be' drawn in through the automatic valve 59 or 65.

In some cases it may be desirable to place the pump and connect-ingvparts out-- side of the receptacle. This form of my invention has been illustrated in Figs. 18 and 19. All parts can readily be placed outside the receptacle, except the intake tubes 49, and the valve casing 46 connecting them. These are of course arranged within the receptacle in the same way as described above in connection with the main torni ot my invention." The tube connecting the valve casing 46 with the valve casing 42 in this case extends through the wall otthe receptacle and consists preferably ot two parts 45', 45 connected by a. union 45:22 All other part-s are the same as in the other form and are preferably proterted by a tube 68 surrounding them,` this tube being secured to the receptacle by suitable clampingrings 69. The operation of this form of my invention is exactly the same as described above with regard to the main form.

The operation of my improved liquidprojecting device is very simple, while at the same time it .is very effective. By a succession ot quick in-and-out strokes I obtain a practically continuous stream ot liquid issuing :lrom the nozzle of theV receptacle.' The receptacle may be held and the pump operated in any desired position. The intake tubes are arranged in such a manner that the free end of at least one of them will practically always be immerse-d in the liquid.

lVhile my device has been described in connection with a fire extinguisher and is primarily intended for such use, it may be adapted tor other uses, such as for instance vthe receptacle to withdraw liquid, thereftrom, aid .pump being provided with an outlet to discharge such liquid, a piston ar-` ranged to reciprocate, in said cylinder, a handle tor operating said piston, said handle being capable oit turning relatively tothe cylinder, a plug which is normally stationary and disconnected from the handle, said plug being arranged adjacent to said outlet and capable of turning relatively to the cylinder about the same axis as saidhandle, a valve carried by said plug and controlling said outlet, and means for connecting said handle and plug so that they will turn in unison about the same axis.`
