2,206,815 RECEPTACLE FOR LIQUID SPRAYERS Erwin G. Horton, Hamburg, N. Y., assignor to Trico Products Corporation,jBnflalo, N. Y.

Application April 1, 1939, Serial No. 265,617 7 Claims. (01.22145) This invention relates to washers for the windows of vehicles, and to devices of a similar na-' ture, and has particular relation to an improved means for mounting parts ofsuch devices and for rendering them accessible for filling with the liquid with which they operate.

Devices of this character'include a container for liquid to be sprayed or otherwise applied to a window, conduit means for carrying the liquid to or directing it against the window, and means for pumpin'gthe liquid from the container and through such conduit means. The present invention provides an improved structure for connecting and mounting the several parts, whereby the container may be easily attached or detached, and "when attached will be securely held in place, and also provides an improved and efil cient filler valve means, whereby the container may easily be filled and refilledwith liquid.

These and other objects and advantages, including those arising from the novel structure, and arrangement of the several parts, will become apparent from the following description of the typical embodiment of the invention shown in the accompanying drawing, wherein:

Fig. 1 is a front elevation of the container, pump and supporting parts; V

Fig. 2 is a plan viewof the parts shown in Fig.

1 except for the pump parts which are indicated by broken lines;

Fig. 3 is an exploded perspective view showing the supporting means, filling valve, and pump parts in disassembled relation;

Fig.4 is a fragmentary vertical sectional view through certain of the parts shown in Fig. 3, on a larger scale;

Fig. 5 is adetailed perspective view of ,fragments of the parts for securing the container to the supporting means; and

Fig; 6 is a detail vertical sectional view taken through the lower central part of the supporting bail shown in Fig, 1.

As shown in the drawing, the device includes a pump unit ll having an intake and an outlet for liquid, and also having a connection to. a source of variable pressure, such as the intake manifold of an internal combustion engine, which variable t drawn into the pump unlt. Also opening into .or to another suitable support.

the pumpunit through part I2 is a fitting I6 connecting a conduit I! that may extend to a suitable source of variable pressure (such as the intake manifold of a vehicle engine) not shown. An outlet conduit l8 from the pump unit may carry liquid into adjacency with a vehicle windshield or the like. The structure of the unit II and the connectionsfor the conduits extending to and from it may be of the kind shown in my co-pending applicationSerial No. 265,616, filed on even date herewith, entitled Windshield clearing system.

Supporting means for the pump unit II include a plate 19 having a depending integral bracket part 2| and integral upstanding bracketv parts 22. Openings 23 are provided in the bracket parts for suitable fasteners by which the plate may be secured to a dash board it of the vehicle The nipple l3 of pump unit ,ll extends through an opening 25 in plate l9 and is secured by a nut 26 threaded thereto. A cap 21 secured against the lower surface of plate l9 by suitable fasteners, such as rivets 28,

receives the open upper end of a container 29. The latter, preferably in the form of a glass jar, is clamped in place by means including a screw 3? and a bail St. The latter may comprise a U shaped piece of strap metal whose ends are notched to provide each with a narrow stem part 32 and shoulders 33; joined by angular parts 3 The plate 19 has its opposite sides provided with recesses 35 whose mouths are restricted by screw also being screw-threaded through-the member 38, aslshown in Fig. 6. A foot member is swivelly connected to an end portion of screw 31, for bearing upon the bottom of,-contamer 29, and ahandle II is formed on the other end of the screw. It will be noted that when the screw 31 is tightened, tending to draw the bail downwardly relative toplate l9 and container 29, V the end portions of the bail tend to move toward one another due to downward bowing of the central part of the bail. This action'dissipates any tendency of the upper portions of the bail to become displaced from within the recesses 35.

For filling the container without removing it from the assembly, a filler .opening 42 through plate l9 and cap 21 is provided. A closure43 for the opening 42 has an aperture 44 through which tube I extends, and a finger 45 projecting beyond the edge of plate I9 by'which the closure may be moved pivotally about the tube. Aperture 44 is sufficiently larger in diameter than tube !5 that a spacer 46 in the form of a lock washer may be disposed within it and about the tube.

The bottom of the spacer 46 abutsthe plate l9 and the top thereof abuts an annular shoulder 41 on casing part l2. Around the latter and abutting surface 48 of part I2 is a ring 49 having.

radially extending resilient fingers 5|. A gasket 52 and washer 53 are disposed about threaded nipple I3 between cap 21 and nut 26.

Upon tightening of the latter compressing spacer 46, it will be seen that annular shoulder 41, spacer 46, plate 19 and cap 21, gasket 52, Washer 53 and the nut 26 will be firmly clamped together against relative displacement. The closure 43 will be pressed against plate H! by the resilient fingers 5!, so that it will be held irlctionally against accidental displacement, although it can be pivotally moved about the longitudinal axis of tube E5 to a position uncovering the filler opening 42. I

In the preferred form of the invention the rivets 28 are so placed that the heads of two of them are disposed on opposite sides of closure 43, and, by extending above the surface of plate l9,

.require that the closure be elevated slightly bepump casing having anannular shoulder and an internally and externally threaded 'nipple de-.

pending therefrom, a compressible spacer around said nipple and between said shoulder and plate,

a member screw-threaded externally to said nipple for compressing said spacer between the plate and said annular shoulder, a container, means including a bail secured to said plate for securing the container beneath said Dlate,a pump inlet pipe threaded internally into said nipple and extending into said container, said plate having a filter opening therethrough for passing liquid into said container, a closure for said opening disposed upon said plate. and about said spacer, and a resilient member disposed about said shoulder and flexed between the pump casing-and said closure for resisting displacement'oi: the latter.
