APPli atiOIL May 25, 1955, SerialNo. 510,881,

2 Claims. (Cl. 222323) Theobject-of the invention is to provide improvements in holders for pressure-actuated :canisters, and especially in a.holder..for such canisters-that embodies a handle thatingeneral follows in shape and inclination of thehand-v grip ofcertainautomatic firearms, which-as the-result of longs-use; undenevery known.condition hasproved'to be the-.most accommodative to ends hand-when aimingsuch-:firearm,--and likewise the dischargeron fire of a pressurecanister; also means to removably ordetachably se-- cureto said hand-grip canisters of widely varying-sizes; and a triggerlike lever by which movement of a fingerof the operator is adapted. to depress the spring-positioned plungerof such, a canister, and thereby release therefrom as much. as, may be desired of its contents.

Another and more specific object is to provide a device of. ;this; type,..which comprisesa hand-grip of the simplest form that can beproducedupon moulding and rabbeting machines, and :Which is provided with a longitudinally eX-- tending groove; in which. is pivotallysecured a levertof whichone endservesas-a manufily actuatable trigger,

while the opposite angularly related portion extends into the, proximity of. and is. adapted. to. engage and depress the spring-positioned plunger of the type. of canister in question, for as long as it is desired that its contents shall bedispensed therefrom in a. jet or stream ofatomized particles;

A further object is to providein such a device a supportingelement for a canister, which comprises in general a plate that is bifurcated at one endto receivewbetweenits, spaced arms a portion of said hand-grip, while it's opposite'end portion; is bifurcated. toprovide a pair of oppositely curved arms, adapted to yieldinglygrip the upper portion of a canister, and operatively. maintain.

such, upper portion in suitable close proximity to the plungerengageable end of said lever, while. between said.

first-mentioned; pair of arms said element, is provided witha central portion, that normally enters :a recess of correspondingshape in said hand-grip, and thereby co.-v operates witha pivot securing-saidfirst armsto said hand gripto prevent angular movement of said element-with:

respect to said grip.

Still another object is to provide a modified form of, the device, which comprises a plate having an; elongated aper.

ture=of generally figure 8 shape, the larger endportion of which is adapted to pass the uppermost. closure (or. other desired) portion of a canister, while following such closure portion having beeng shifted into: the smaller portion of said aperture, it is fixedly though removably fiicieatlv str tothe. extent desired,

atent- 2,82%,578 Patented Jan. 21, 1958 ice Anda still further object; is to provide a further slightly modified form of the device, which comprises a plate havinga generally circular aperture, whose periphery; is interrupted by a pair of radial cutouts, throughwhich radial projections from'a canister may pass, as the adja cent portion of said canister passes through said aperture,- following which upon. turning the canister as witha bayonet locksaid 'projections-are shifted into positions above the uninterrupted-portions of'said aperture, where. thereare preferably yieldingly maintained-by said projections sinkinginto slightly depressed diametrically related-- surfaceportionsof said plateadjacent tosaid aperture.

Within the upper P rt on o sa d's t s i al yls z. cured an approximately central intermediate portion of a lever, that essentially comprises anupper forwardly projecting actuating arm 4 and a generally downwardly extending trigger arm 5." The pivot'al mountingis main: tained by ineans of a transverselyextending rivet 6 or, the like; While the trigger arm of said lever is freeto swingfromaninoperative-position;beyond the transverse limitsof said-slot-Z; 'toaretacted position more withinyet not wholely-shelteredby the sides of said slot, aswhen it is forced-'rearwardly by manual; pressure of a finger of'the; operator, while his hand surrounds said grip as a'handle',

For operatively supporting a canister infixed relation to said handle-grip, a supporting element is provided thatessentially:comprises-a bifurcated rear end portion;

ecured-to said grip, .and -a bifurcated fOIWQIdjPbl'llOll characterized by resiliently positioned arms, to.-yield,-

ingly receivea convenient portion ofa canister,;as;in-

dicatedineFig; .1. Said supporting-element may bea pair; of: properly: spacedirstittr wire membersor thelike; butv 3 is here shown as comprising a plate 7, whose rear end is bifurcated to provide a pair of upwardly directed parallel flanges 8 between which the upper portion of said grip is positioned slightly'beneath the level of the rivet 6, and secured together in fixed relation by means of a single rivet 9. I I

Between said flanges the intervening rearwardly directed edge of said plate is provided with a preferably flat portion 10, that is positioned in a transversely extending slot 11 in said grip, and which tongue in indirect cooperation with said last-mentioned rivet fixedly maintains said grip and said plate in predetermined angular relation. The forward portion of said plate is bifurcated to provide a pair of resiliently positioned slightly arcuate arms 12,

which in cross section are flanged at 8' to increase their:

vertical rigidity and which makes them of generally L- shaped cross section, the lower flanges of which lie in a common plane and normally enter the vertically narrow, circumferentially extending groove 13, that inevitably occurs at the junction of the closure 14 with the uppermost, inwardly sloping, slightly connical top wall 15 of said canister, beneath which said canister may be of any convenient shape, but which is here shown for example, as comprising a lower cylindrical portion 16, closed at its bottom 17, and merging into an abbreviated upper cylindrical portion 18 by means of an intermediate conical section 19. Resilience of the arms of the forward portion of said plate may be increased by providing a V-shaped cutout 20 as indicated in Fig. 1.

Such a canister contains any one of various kinds of fluids under pressure, and which fluid is adapted to be discharged in a gradually expanding spray 20 from an orifice 21, that is directed laterally from a centrally positioned, upwardly directed plunger 22, against or closely adjacent to which the free end of the lever'arm 4 is normally positioned. With the several elements and their respective parts positioned as shown in Fig. 1, and the hand of the operator firmly grasping the handle-grip, rearward movement of the trigger portion of said lever into the slot 11 causes said lever to depress said plunger, and while thus under perfect control permit just as much or as little of the canisters content to be ejected from said orifice as may be desired.

Referring to Figs. 6, 7 and 8, a slanting rectilinear handle-grip 25, has secured to it by means of a rivet 26 a pair of rearwardly directed spaced parallel ears 27, that comprise integral extensions of a substantially horizontally positioned plate 28, which is transversely stiffened by a peripherally extending flange, 29, that comprises a generally U shaped continuation of and which connects said ears. The forward portion of said plate graduallywidens from said ears to form an intermediate portion 30 and a freely extending terminal portion 31, in which is a generally 8-shaped aperture, that comprises a rearwardly positioned larger portion 32, a forwardly positioned smaller portion 33, and an intervening slightly constricted portion 33'.

A canister 34, having an upper circular closure 35 providing a-slightly undercut annular recess 36, is attached to said plate by first inserting said closure through the larger rear portion of said aperture, and then either by a direct rectilinear or rotary motion is forced past an intermediate constricted portion 33' of said aperture, until the recess 36 of said canister receives the circular edge of the smaller portion of said aperture. The laterally opposite sides of said plate in the vicinity of said constricted portion are sufiiciently resilient to expand or separate enough to pass said closure recess surfaces, and then contract and yieldingly secure said canister in fixed operative position with relation to said plate and thereby with said handle-grip as well. i

.The rearmost horizontal portion 37 of said plate. is tightly lodged within agsawcut or the like 38 in said handle-grip,,so that in. conjunction Iwiththe rivet 26 said 75 plate and said grip are normally 4 secured in fixed angular relationship. The intermediate portion 30 of said plate is provided with an upwardly deflected ear 39, to which by means of a rivet 40 there is pivotally secured thereto the central portion 41 of a lever that essentially comprises a depending trigger portion 42, and a forwardly projecting actuating portion 43, whose outer free end normally terminates either close to or preferably in light contact I Referring to Figs. 9, 10 and 11, it will bev understood that the fragmentary portion of the canister-supporting plate here shown is a modification of the corresponding portionof the plate shown in Figs.-68, with the same handle-grip and actuating lever hereinbefore'

ing used with it. Said plate 28 is provided with the same marginal stiffening flange 29, while instead of the S-shaped aperture there is provided a circular aperture 50, having diametrically positioned radially projecting enlargements or offsets 51, while circumferentially between said ofisets' there are positioned diametrically related depressed recesses 52. The radially enlarged annular periphery 53 of the closure of a canister 54 is provided with diametricah ly related, radially projecting lugs 55, which are adapted to pass through the enlargements 51 as said closure passes through said aperture, after which said closure can be rotated until its lugs are in' alignment with and fall into said recesses, whereupon whatever form of actuating level may be present is operative to depress the orifice-controlling member 56, as before described. Removal of said canister and its closure from said plate is accomplished by reversing the rotation of the former, until its said lugs are free to be withdrawn through said offsets and said closure from said aperture.

Illustrating the well known construction and operation of the valves present in such canisters as those herein referred to, reference is made to United States Patent No. 2,777,735, whose Fig. 2 is here reproduced as Fig. 12 and which shows the general mounting of a valve head 224456, that corresponds with the respective valves 22, 44, 56 hereinbefore referred to. The essential elements of such a valve and adjacent parts comprise the usual upper wall 60 of the closure of the usual canister, having a central upwardly projecting cylindrical extension 61, topped by a wall 62 having a central port 63, through which slidably reciprocates a tubular valve stem 64, that communicates with an internal bore 65 in said valve head, and from the upper portion of said here leads a generally horizontally extending discharge bore and orifice 21-45. The lower end portion of :said valve stem is provided with elongated ports 66 below a resilient packing washer 67 that seals the upper port 63, while its lower end is closed by a polygonal cap 68, that limits the effective vertical length of the ports 66 and at the same time serves as a guide in slidable engagement with the interior of a depending cylindrical casing 69,

whose uppermost outwardly flanged portion 70 is secured between the packing washer 67 and a suitable annular shoulder upon the inner surface of the upward canister extension 61. The under side of said cap 68 is provided with a cross slot 71 and rests upon the upper end of a' depending tube 72, thatis secured in the lower restricted end portion 73 of said casing, while a coil spring 74 enconstruction manually drawing the trigger 42 towards the handle-grip 25, for example, causes the triggers actuating portion 43 to depress said valve head and thereby the stem 64 and cap 68, so that the internal pressure of the canister is free to force its contents from the discharge orifice, as hereinbefore described.

Having thus described my invention, What I claim and desire to protect by Letters Patent of the United States is:

1. A manual holder for canisters containing fluids under pressure that have a closure top and also have a discharge orifice in said closure top controlled by a member that is normally yieldingly positioned, comprising a handle-grip, a plate fixedly secured to and forming a forward extension of said handle-grip, said closure top on said canister forming with said canister an intervening annular groove said plate being provided with an elongated aperture of which one end portion is sufiiciently large to pass the closure while its opposite end portion is adapted to at least one-half encircle the annular groove, and the intermediate portion of said aperture being sufliciently constricted to prevent the accidental escape of said closure from the smaller end of said aperture, and a lever having an intermediate portion pivotally secured to said handle-grip, while one of its ends extends in variably close proximity to said handle-grip to form a trigger, and the opposite end extends into operative relation with the orifice-controlling member of said canister, to release the contents when said trigger is shifted.

2. A manual holder for canisters containing fluids under pressure that have a closure top and also have a discharge orifice in said closure top controlled by a member that is normally yieldingly positioned, comprising a handle-grip, a plate secured at one end to and forming a unitary forward extension of said handle-grip, a closure on said canister forming with said canister an intervening annular groove said plate having a peripheral flange to stiffen it transversely and an elongated substantially 8- shaped aperture of which one end portion is sutficiently large to pass the closure of a canister While its other end portion is adapted to at least one-halt encircle the annular groove beneath such closure, and the intermediate portion of which aperture being sufiiciently constricted to prevent the accidental escape of such canister from the smaller end of said aperture, and a lever having an intermediate portion pivotally secured to an ear carried by said handlegrip, while one of its ends extends in variably close proximity to said handle-grip to form a trigger, While the opposite end extends into operative relation with the orifice-controlling member of said container, to release the contents when said lever is shifted.
