Application med apron 2c, 1926. Serial No. 97,586.

My invention relates to fountain syringes and more particularly to one of that type adapted for physicians or travelers use in that it may be collapsed into a comparatively small space for storage or transportation and, when desired for use,may be assembled and extended to provide the necessary liquid container and drainage. I

Among the .principal objects of the present invention are to provide a liquid tight, collapsible receptacle having a discharge nipple which may be so assembled with the receptacle as to preclude its accidental dislocation when the device is in use and whereby substantially complete drainage of the receptacle may be insured.

It is also an object of the invention to provid'e, in combination with the receptacle, a-

container or housing comprising a body ele ment with which the container may be interlocked to prevent rattling of the collapsed elements and including a cover which may be employed as a hanger for the receptacle when the device is in use.

-In accomplishing these and other objects of the invention I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein Fig. 1 is a longitudinal, vertical section of the receptacle and housing elements of the syringe, shown in extended or functional position. I

Fig. 2 is a cross section of the device, illustrating the parts collapsed and housed.

Fig. 3 is a perspective view of the device,

. showing the receptacle extended and in process of assembly for use.

Fig. 4 is a vertical section through portions of nesting sections of the rece tacle.

Fig. 5 is a similar viewof a modified form of telescoping joint for the nesting sections. Fig.- 6 is a detail perspective. view of the tube nipple.

'Fig. 7 is a detail perspective view of the spider for interlocking the receptacle and c I seat on the top of the neck 6 and castellated housing.

Referring more in detail to the drawin s: 1 designates a receptacle consisting o g a plurality of tubular members of non-corro'dible metal, elliptical in cross section, tapered downwardly and of graduateddiameters respectively to permit the members to nest when the receptacle is collapsed and to interlock in sealing relation when the receptacle is extended for use, each of the tubular sections, except the upper one, being provided with channel offsets 2 at their upper proof and flexible material, against which the lower edge of a next larger section may frictionally contact to effect the sealing and interlocking relation 'of the respective sections, the top section of the receptaclebeing provided with a rolled head 4 to eliminate a sharp exposed edge, stifien the receptacle and enhance its appearance. 4 a

The bottom section of the receptacle is provided with a central aperture 5 and extending through the aperture to the interior of said bottom section is the internally screw threaded nec'k'6 of a spider 7 comprising a central hub 8 and long and short legs 9 and 10, arranged in pairs to extend coincidently with the long and short axes of thereceptacle. Each 'ofthe legs 9 and 10 is provided with an aperture 11 and extended through said apertures 11 and corresponding apertures in the bottom of thelower receptacle section are rivets or the like 12, whereby the .spider is permanently attached to the receptacle, thespider being sealed to the bottomof' the receptacle by riveting, welding or otherwise to 'avoid leakage between the receptacle and spider. Each of the spider legs has a downwardly offset lip 13 for resting on the bottom of a housing presently described, to space the receptacle from the neck 6,- and a'chambered head 19 adapted to to afford free communication through its side wall to theinterior of the nipple. lhe

upper edge of the head 19 is provided with prongs 20 adapted for projection through apertures 21 in a dome 22 to fix the dome on the nipple head so that the dome may constitute a permanent cover for the nipple.

dimension relative to the nipple and spider The dome 22 is semi-spherical and of such" collar as to space the lower edge of the dome above the bottom of the receptacle sufli ciently to' provide free flow of liquid beneath the dome and through the nipple head to the interior of the nipple. The end of the stem 17 is corrugated to form a holding connection for the ordinary syringe tube 23.

24 designates the body of a housing for the receptacle 1, having a contour corresponding to that of the receptacle and of a depth sufficient to freely house the receptacle therein, the bottom of said housingmember having ventilation and drain ports 25 and up-struck latch ears 26, the latter being directed inwardly to receive the spider lips 13 when the latter are turned to project them beneath the latch ears on the housing. On

the top member of the receptacle 1 is fixed end oppositethe hinged cover with a keyhole slot 31, the slot portion of which is directed outwardly so that when the cover is applied to a nail or the like on a wall or other support, the shank of the nail may rest in the slot of the aperture to anchor the syringe on its suspended support (Figs. 1 and 3). When the syringe is supported. in this manner the housing 'body engages the wall or other support to space the lower portion of the rece taele therefrom and maintain the receptacl; in upright position.

It is apparent that the device when collapsed may be contained within the housingand occupy but a limited space in a hand bag-j, or other carrier or within a storage cabinet, the outside dimensions of the receptacle being sufficiently. less than the inside dimensions of the housing to permit the tube to lie coiled about the receptacle and within the housing (Fig.2).

g It is further apparent that when the receptacle is disconnected from the housing, the sectionsmay be completely separated to facilitate sterilization, and that when the receptacle is extended the sections are sealed together to preclude leakage.

In the modified form of joint shown in Fig. 5 the lower edge of the receptacle sec-.

tion is cupped inwardly to form a retaining seat 32 for-a packing ring 33 and the upper edge of the section provided with a keeper lip 34 for engaging the top of the packing ring so that the packing rings are compressed therebetween. v

When the device is to be used, the cover member of the housing is swung back on its hinged connection and the receptacle and tube removed from the housing. The tube is then projected through the collar in the bottom of the receptacle and the nipple threaded into the collar to form a close joint with the collar. The tube is then strung through the central aperture in the bottom of the housing body and the receptacle given a part turn to locate the spider ears beneath the latch ears on the body and lock the receptacle to the body. Liquid is then placed in the receptacle and the receptacle hung from a wall or other support by means of the keyhole slot. With the parts so arranged the device may be used in the ordinary way, liquid flowing beneath the dome in the bottom of the receptacle and through the castellated head and nipple into the tube, suction induced .by the flow draining substantially the entire quantity, of the liquid from the receptacle through the opening between the dome and the bottom of thereceptacle.

After the device has been used it may be collapsed by an operation reverse to that for assembly-and replaced in a carrier or cabinet, the space required for such storage being substantially less than that of a fountain syringeof'the ordinary construction.
