UNITED STATES SAMUEL M. COZAD, DE LOS ANGELES, CALIFORNIA.
Application filed October 12, 1922.
To all whom it may concern Be it known that I, SAMUEL M. Cozeo a citizen of the United States residing at Los Angeles, in the county of 1 10s Angeles and State of California, have invented new and useful Improvements in Liquid-Dispensing Devices, of which the following is a specification.
My invention relates to liquid dispensing devices, and a purpose of my invention is the provision of a device of this character by means of which the dispensing of a liquid in, predetermined quantities can be automatically effected, the invention'm its present embodiment being particularly adapted, although not necessarily, forthe dispensing of bleaching liquids as used 111 laundries.
Although I have shown and described only one form of liquid dispensing device embodying my invention, and will po nt out the novel feature thereof in claims, it is to be understood that various changes and modifications may be made withoutdeparting from the spirit of the invention and the spirit and scope of the appended claims.
In the accompanying drawings,
Figure 1 is a View showing in side eleva-v tion one form of liquid dispensing dev ce embodying my invention;
Figure 2 is a top plan view of the device shown in Figure 1;
Figures 3 and 4 are vertical sectional views taken on the line 34 of Figure 1 and showing detached parts of the device;
Figure 5 is a fragmentary detail perspective view of the pivot means for the receptacle supporting lever.
Similar reference characters refer to similar parts in each of the several views.
Referring specifically to the drawings, and particularly to Figure 1 my invention, in its present embodiment, is shown as comprising a hollow casing 15 which communicates at its lower end with a connecting nipple 16 screw threaded for the purpose of providing a connection between a tank adapted to contain and from which any liquid such as bleaching liquid is adapted to be dispensed. Communicating with the side of the casing 15 is a pipe 17 having a discharge nozzle 18. The pipe 17 is formed with upstanding ears 19 provided with segmental openings 20 through which is extendeda ivot bar or pin 21. As clearly shown in igure 5, the pivot bar 21 is of substantially SeriaEl No. 593,970.
triangular form in cross section to rovide a relatively sharp edge 22 which is adapted to contact with the lower corners of the segmental openings 20 to provide a pivot upon which the bar is adapted to rock. For the purpose of confining the bar 21 against longitudinal shifting within the openings 20, a screw 23 is threaded in one end of the bar so as to engage a washer 24:, as clearly shown in Figures 2 and 5.
A lever 25 is rigidly secured to the bar 21 at a point between the ears 19 so that the edge 22 of the bar functions as a pivot point about which the lever 25 is adapted to swing.
One end of the lever 25 is bent downwardly and terminates in a hook 26, upon which lat ter a bail 27 of a bucket or other suitable receptacle 28 is adapted to hang for supporting the receptacle in receiving position with respect to the discharge nozzle 18. The opposite end of the lever 25 is adapted to slidably receive a weight 29 provided with a set screw 30 for locking the weight in any desired position along the length of the lever. For the purpose of preventing distortion of the lever and eliminating the noise incident to the return of the lever to its normal position, a bumper 31 is secured to the side of the casing 15 so as to project above the up per end of the casing and to be engaged by the lever as it swings downwardly. This bumper is preferably formed of rubber or other suitable material and is slotted to accommodate a projection 82 (Figure 4), to which latter is secured a guide rod 33. The guide rod 33 is bent at its upper end to provide a hook 34, and this rod is associated with the lever 25 so as to guide the latter during vertical movement with the hook li1niting the upward swinging movement of the ever.
As clearly shown in Figure 4, the casing 15 is provided with avalve chamber 35 and a discharge chamber 36 provided with a dis- 2 charge opening 37 which communicates with the pipe 17. The walls of the chambers 35 and 86 are separated by an annular flange 38 which is adapted to form a seat for a shoulder 39 of a subsidiary casing 10. This casing 10 is provided at its lower end with a port 41 controlled by a valve 42. lVith the casing 40 applied to the casing 15, it i disposed within the chamber 36, with the valve disposed in the chamber 35. The casin 40 is provided with an annular flange 43 w iich is adapted to be bolted or otherwise secured to a corresponding'flange 44 formed. on the casing 15 so as to provide a cover for the casing and to close the upper end of the chamber 36.
The valve 42 is adapted to control the flow of liquid from the chamber 3 5 to the port 37, and thi valve is provided with a stem 45 which is threaded to receive nuts 46 for setcuring a deflecting plate 47 thereon. The upper end of the stem 45 is connected toa plug, 48 mounted for vertical. movement within socket 49- formed: on the upper end of the casing 40. The deflecting plate 4:? is designed for; thepurpose 0t directing the liquidentering. the casing 40 through the port 41 toward: the port 37 and: subsequently into the; pipe; 17. In this manner, the possibility: of leakage-between the plug 48 and: the
socket 49 i prevented.
As shown in F'gure 3, the hookedend 34 ot the guide bar 33:- isextended downwardly in parallel relation to: the guidebar and: into;
engagement with the flange: 43. At this point; the guide bar isbent at right angles to provide a lip 50' which merely contacts with the flange 43.
For actuating. the valve 42, the lever 51 is extended. through an opening 52 formed in the socket 48,. and-as shown in Figure 1, this lever is adaptedv to be operatively connected to the lever 25 through the medium 0t latching means. This latching means in the" present instance comprises a1 latching tongue 53 formed on the lever 25 and adaptedto engage azlatching plate 54 pivotally sustained upon the lever 51 by means of a pivotpin 5'5 Thearrangement of the lever and plate is such that the lever normally engages the plate to hold the lever 51 in substantially horizontal position wherein the valve 42' is open. The degree of movement of the lever 51 is adapted to beregulated by; means. of aweight 56 adjust-ably mounted. on the lever and. adapted to be locked in any adjusted position by means of a set screw 57.
The operation of the dispensing device is as follows :Liquid supp-lied to the casing 15 from: the: tank, not shown, is adapted to be discharged into the receptacle 28 when the valve 42 is open. In the open position of the valve 42,- the lever 51 is latched in horizontal position by. the latch member 53 engaging the latch plate 54', all as clearly shown. in Figures 1 and. 2. A weight 29 of the lever 25; is adjusted to counterbalance the: lever until the liquid discharged into the receptacle 28 reaches av predetermined quantity. hen this occurs, the weight of the. liquid overba lances the weight of the lever and weight 29,: thereby causing the lever to swing upwardly about the pivotb-ar. 21 as a center to move thelatcli member 53 outo'f" engagement with the latch plate 54. Under the action of the weight 56 the lever 51 is now free to swing upwardly about the pivot point 58, thereby moving the head 48 upwardly within the socket 49 and thus causing the valve 42 to close the port 41. With the port 41 closed, the supply of liquid to the receptacle is discontinued, and with the receptacle containing the pretermined quantity of liquid.
In order to reset the dispensing device, the latch plate may be manipulated by virtue of its pivotal mounting to. again engage the latch member" 53,. it being understood that it isfirst necessary to restore the levers 2'5 and 51 to the positionsshown in: Figure I claimas my invention:
