' 3 Claims.

This invention relates to a syringe and more particularly to What is commonly known as a fountain syringe.

The primary object of the invention is to enhance the appearance of articles of this character by concealing the hose from view in a cabinet when not in use, said cabinet being of an attractive appearance which in no way suggests the utilitarian purpose of the device.

Another object of the invention is to render the device capable of instantaneous use without requiring the usual assembly operations, such as attaching the hose and nozzle to the ordinary collapsible reservoir.

Still another object is to preserve the contents of the reservoir of the syringe from contamination when the device is not in use, and also to provide for the disinfecting or sterilization of the nozzle with which such devices are usually equipped.

A still further object is to more efiiciently use the space enclosed by the cabinet so that a device of maximum liquid-containing capacity may be housed in'a minimum amount of space.

The above and other objects may be attained by employing this invention which embodies, among its features, a substantially rectangular liquid reservoir carrying, on its rear side, a hollow extension of less width than the reservoir, which extension opens into the reservoir and serves as a support for the usual hose employed with syringes of this character when the latter is not in use.

Other features include extensions on the side walls of the reservoir which, together with the extension on the reservoir proper, define vertically extending chambers on opposite sides of the back of the devicein which the coiled hose is received, and concealedby the side wall extensions.

Still other features include a cover which is adapted to close the upper, open end of the reservoir to prevent the introduction of dust and dirt thereinto, and an extension on the cover adapted to overlie the upper end of the coiled hose to cooperate with the extensions of the side walls of the reservoir in completely concealing the coiled hose from view.

In the drawings:

Figure 1 is a perspective view of a syringe embodying the features of this invention,

Figure 2 is a rear end view of the syringe,

Figure 3 is a vertical sectional view through the syringe,

Figure 4 is a horizontal sectional view taken substantially on the line 44 of Figure 2,

Figure 5 is a vertical sectional view taken substantially on the line 55 of Figure 4, and

Figure 6 is a vertical sectional view taken substantially on the line 6-6 of Figure 4.

Referring to the drawings in detail, this improved syringe comprises a receptacle designated generally Iii which is composed of a bottom wall it having formed integrally therewith a rearward extension l2 which is of less width than the bottom and is provided with a drain opening I3 which is surrounded by a depending nipple It. Ex

tending perpendicularly to the forward edge of the bottom I I is a front wall l5, and extending perpendicular to the side edges of the bottom wall 8! are side walls It which are coextensive with the front wall It and joined thereto to provide a liquid-tight joint at the junction of the front and side walls. A back wall l'l extends perpendicularly to the bottom ii in spaced parallel relation to the front wall 55 so as to define a main 5 reservoir it for the reception of the liquid to be employed. As illustrated in Figure 3, the back wall IT projects above the general level of the top edges of the front wall 55 and side walls [6, while the lower end of the back wall is coextensive with the front and side walls, which, as illustrated in Figure 3, project somewhat below the bottom H to define a hollow space 89 so as to provide an air chamber between the bottom end of the receptacle and a surface upon which it may stand.

Formed in the back wall ii and extending upwardly from the bottom H at its junction with the extension '12 to a point in a plane with the upper edges of the front and. side walls is an opening 20. Extending vertically along the marginal edges of the opening 2!} from the bottom Wall l2 to a point in a plane with the upper edges of the front and side walls 15 and it are spaced, parallel walls 22 which are joined by a rear wall 23 to define a chamber 24 which is wholly open to the major reservoir or receptacle [8. The top of the chamber 24 is closed by a top wall 25 and the rear wall 23 extends upwardly beyond the upper ends of the sides 22, as illustrated in Figure 6, and is provided with a hanger slot 26, by means of which the device may be suspended on a nail or the like driven into a wall. Extending upwardly in spaced, parallel relation to the walls 22 at one edge of the bottom extension 12 is a wall 21 which cooperates with the rear wall 23 and the back wall H in defining a chamber 28 which is wholly open at its upper end, as will be readily seen upon reference to Figure 6. The side walls I6 are each provided with rearward extensions 29 which cooperate to define longitudinally extending chambers 30 on opposite sides of the chamber 24, which accommodate a rubber hose 3| when the same is coiled about the extension defined by the walls of the chambers 24 and 28.

A cover, designatedgenerally'32; is adapted. to be seated. on the upper edges of the front wall l and the side walls l6, and this cover comprises a substantially transversely arched body 33, extending transversely of which is a partition wall 34 which divides the cover into a forward chamber 35 and a rear chamber 36s the rear end of which is wholly open. As illustrated in Figure 3, the partition wall 361s so positioned with relation to the cover when it is in" place on the receptacle that itxengages the upper end of the back wall I! so as toefiectivelyseal the reservoir l8 against the entrance of dust and dirt.

It is preferable thatthe side walls IS, the front wall !5 and. the cover 32 be formed of an opaque or translucent substance such as an opacified.

plastic,v in which eventI find it desirable to provide a series of verticalv windows 3'! in either the front Wall IE or the side walls It, which windows are preferably arranged not only to lend ornamental value, but also to serve asliquid level indicators by means of which the level of the liquid contents of the reservoir It may be determined without removing the cover 32.

In-use,.the hose 3| is uncoiled, and the reservoir |8 filled with the desired liquid. It will be noted that inasmuch as the extension reservoir 24 is in. direct communication with the main reservoir |8,. the latter may be made to minimum dimensions without seriously impairing the total capacity, of the unit. When it is desired: to restore the. device toinactive condition, the hose 3! is i coiled about the extension defined by the walls of. the. chambers 24 and 28. so as to lie within. the chambers 30 and be wholly concealed from.

view. Ihe hose will be retained. in place. at the upper end by the upward extension of the wall 23 and it need not be disconnected from the nipple M, so that the device is ready for instantaneous use. In order to retain the nozzle on the hose and preserve it in a sanitary condition, I find it desirable to introduce into the receptacle 28 a suitable disinfectant into. which.

the nozzle on the end of the hose is plunged when it enters the receptacle. Should it be. found necessary to allow some of the liquid to remain within. the reservoir I8, the cover 32-will effectively prevent the entrance of dust or dirt into the reservoir and will cooperate with the top wall 25 of the auxiliary reservoir or extension. 5

chamber 24, as will be readily understood upon reference to Figure 3.

when not in use, in a sanitizing substance.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that various changes in the details of construction and combination and arrangement of parts may be resorted to within the scope of the appended claims without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what I claim is:

1. In a cabinet syringe; a cabinet having a main reservoir for reception of liquid to be employed; a hollow hose-supporting extension on the reservoir, theinterior Of which communicates with the main reservoir to increase. the capacity of the reservoir; and a discharge hose connected to the reservoir and arranged to be coiled around the extension when the hose is not in use.

2. In a cabinet syringe; a cabinet having an open-top reservoir for reception of liquid to be employed; an open-top disinfectant-holdin receptacle in the cabinet separated from the main reservoir by a wall; the wall extending above the top of the main reservoir; and a removable unitary cover seated on the upper edge of the main reservoir and also overlying the disinfectant-holding receptacle; the cover having an interior partition engaging with said wall when the cover is applied over the main reservoir so as to effectively seal the latter against entrance REFERENCES CITED The following references are of record in the fileof this patent:
