Referring in detail to the drawings, 5 indicates; a housing which is openv at the back and provided with ribs 6 forming opposed internal guideways 1 along the lower portions of the rear margins of its side walls, said guideways being closed at the top as at 8 and open at the bottom. A plate 9 is adapted to be secured by countersunk screws ID to a wall II and has side tongues l2 adapted to be slidably received in the guideways 1. Thus, the housing 5 may be readily mounted on and against or removed from the wall II by sliding it downwardly onto or upwardly off of the plate 9. The housing has a bottom opening I3 through which a, collapsible tube l4 may readily pass.
The device also includes a dispensing unit hav- CgITH- DISPENSING ing a, receiving chamber I5 and including a member I6 removably fitted in the opening I3Nand firmly secured thereinby suitable means, such as a thumb screw l'l threaded through one side of the housingand engaged with theinclined, wall ofacam recess, I8 provided in the edgeof member I6. The chamber I5 has an outlet passage I9 normally closed by a spring-seated valve member 20. A check valve is carried by the member l6' and. includes a casing 2| having a, lower-outletendcommunicating with the chamber l5 and an upper inlet end internally threaded for reception of the threaded outlet neck 22 of the tube I4 to support the; latter within the housing 5. A plunger 23 is mounted in the member l6 and adapted to draw-a quantity of material from the tube I4 through, the-check valve casing 2| and into the chamber l5 upon the suction stroke thereof and to force said quantity of material from said chamber past the valve memberupon the pressure stroke of the same. A spring 24 acts on the plunger to effect one of said strokes of the same, and means, such as an operating lever 25- or 25', or a knob 26, is'provided to facilitate manual actuation of said plunger to effect ,theother stroke thereof.
In the embodiments of Figures 2 and 8, the member I6 is provided with a central opening 21 having an enlarged upper end portion in which is tightly fitted; an annular external flange 28 provided on thevupper end of the check valve casing 2| and supporting the latter within and in spaced concentric relation to the wall of said opening 21'. The lower end of opening 21 is constricted by an annular flange 29. The plunger 23 initheseembodiments consists of a discharge nozzleI extending through and having a sliding fit in. the, flange 29 and provided witha skirt 30 having a sliding fit on the check valve casing 2| and providing the chamber I5 therein. The outlet, passage; I9; is formed in thelower end. of, the plunger nozzle 23. The check valve casing 2| has an internal seat, and a valve ball 3| is pressed upwardly against this seat by the central reentrant portion 32 of a wire spring having arcuate end portions 33 which are snapped into an annular groove 34 provided in the wall of the passage through the casing 2|. Valve member 20 is also preferably a valve ball similarly seated by a similar spring.
In the form of Figure 2, the sln'rt 30 has an external flange 35 at the top; and the helical compression spring 24 is disposed between the flanges 29 and 35 so as to effect the upward pressure stroke of plunger nozzle 23. The lever 25 is provided with a finger piece 36 which is directed upwardly so that the outer end of said lever may be readily pressed upwardly to effect the downward suction stroke of the plunger nozzle 23. The inner end of lever has a fork 31 which rests on the flange 35 and said lever extends through a groove 38 in the top of member l6 and is adapted to fulcrum on a corner of 39 of the latter at the inner end of said groove.
In the form of Figure 8, the spring 24 is interposed between the flange 28 of check valve casing 2| and an external flange 49 of plunger nozzle 23 so as to effect the downward suction stroke of the latter. The lever 25 has a substantially horizontal finger piece 36' adapted to be readily pressed downwardly to effect the upward pressure stroke of said plunger nozzle. The lever 25 extends through a groove 38' in the bottom of member l6 and has its forked end engaged with the underside of flange 40. A pin 39 is disposed across the groove 38 to form a fulcrum for the lever 25.
In the form of Figure 9, the chamber I5 is formed in the member l6 and the rear portion of plunger 23 is reciprocable therein. This plunger 23 extends through a guide sleeve 4i carried by the member I6 and opening at its rear end into the front end of chamber i5. The spring 24 of this embodiment is disposed about plunger 23 and within the sleeve 4| and is interposed between a flange 42 on the rear end of said sleeve and a flange 43 on the plunger to eifect the forward suction stroke of the latter. The lower end of the check valve casing 2|, in this instance, is tightly fitted in a socket 44 provided in the top of member l6, and a port 45 affords communication between the outlet end of casing 2i and the rear end portion of chamber I5. The member I6 is formed to provide a bottom discharge nozzle 46, and the passage i9 extends through this nozzle and communicates at its upper end with the rear end of chamber IS. The check valve casing 2| has a seat therein, and the valve ball 3| is pressed upwardly to said seat by a spring 41. The valve ball 20 is pressed to a seat in the upper portion of passage l9 by a spring 48 in a direction toward the chamber I5.
In operation, a quantity of material is drawn by suction from the tube I4 past valve member 3| into chamber l5 by the plunger 23- upon its suction stroke, and such material is discharged from said chamber l5 through passage [9 past valve member 20 by the plunger 23 upon its pressure stroke. When the plunger is in its normal position, the valve members 3| and 20 are closed to exclude air and prevent the material from drying out in the chamber |5 and/or the tube M. In the form of Figure 2, the plunger is manually operated to draw the material into chamber l5, and spring operated to force the material from the chamber l5. In the other forms, a spring operates the plunger to draw the material into chamber l5, and the plunger is manually operated to force the material from said chamber. When a collapsible tube is emptied, the member l6 may be removed so as to withdraw said tube from the housing and permit the latter to be readily replaced by a fresh tube. Changes in details of construction and other modifications of the invention are contemplated within the spirit of the invention as claimed.
Having described the invention, what is claimed as new is:
1. In a dispensing device, a dispensing unit having a. receiving chamber and including a supporting member adapted to be mounted on a support, said chamber having an outlet passage, a springseated valve member normally closing said outlet passage, a check valve carried by said member and including a casing having a lower outlet and communicating with said chamber and an upper inlet end internally threaded for reception of the threaded outlet neck of a collapsible tube, a plunger mounted in said member and adapted to draw a quantity of material from the collapsible tube through the check valve easing into said chamber upon the suction stroke thereof and to force said material from said chamber past said spring-seated valve member upon the pressure stroke of the same, a spring acting on said plunger to effect one of said strokes of the same, means to facilitate manual actuation of said plunger to effect the other of said strokes thereof, said plunger comprising a discharge nozzle provided with said outlet passage and having a skirt slidably fitted on the casing of said check valve, said skirt having an external flange, said means to facilitate manual actuation of the plunger including a lever carried by said supporting member and having a finger piece at one end and provided with a fork at the other end embracing said nozzle and engaging said flange.
