Patented June 10, 1952 UNITED STATES PATENT "OFFICE Florian A. J. Toman, san Bernardino, Calif. Application September 11, 1950, SerialNo. 184,209
My invention relates to a new and useful improvement in a mustard and catsup dispenser.
An object of my invention is to provide a dispenser which will dispense a desired amount of liquid over a given area in one operation. Another object of the invention is to provide new and improved structure for regulating the amount of liquid that is dispensed in each operation.
Another object of the invention is to provide a dispenser including, a reservoir, a cylinder having the upper end of the cylinder in the reservoir near the lower'end of the reservoir, inlet valves at the upper end of the cylinder, a piston in the cylinder, a pivoted lever for controlling the piston, a one-way valve in the piston and a nozzle at the lower end of the cylinder, said nozzle having spaced apertures for distribution of a quantity of liquid.
The above and additional objects are accomplished by such means as are shown in the accompanying drawings, described in the following description and set forth in the following claim.
In the drawings:
Fig. 1 is a sectional view of my dispenser on a vertical axial plane.
Fig. 2 is a top plan view parts broken away.
Fig. 3 is a perspective view partly in section of my improved dispenser.
Fig. 4 is an enlarged view of the lower portion of Fig. 1.
In the drawings, my dispenser is indicated generally by I. This dispenser includes a reservoir 2. As shown, reservoir 2 is frustro-conical in shape, which is the preferred shape, although other shapes could be used, if desired. A cylinder 3 closes the lower end of reservoir 2. The lower end of cylinder 3 is. closed by a nozzle 4. Nozzle 4 is shaped as clearly shown in Figs. 1 and 4 of the drawings. Nozzle 4 has a plurality of spaced apertures 5 so that liquids which are dispensed through apertures 5 will be distributed over a given area. The top of cylinder 3 is closed by cylinder head 6. Cylinder head 6 has a plurality of inlet valves 1. Each inlet valve 1 includes apertures 8, valve stem 9 and valve disc l0. As shown in Fig. 2, there are four inlet valves 1, although a greater or lesser number of inlet valves could be used, as desired. Within cylinder 3 is a piston I l. Piston l l is secured to piston rod 12 by means of a nut 13. Apertures l4 extend through piston ll. Apertures [4 may be any desired shape, although I prefer that of my dispenser with 1 Claim. (01. 299-97) 1 apertures; H be circular in cross-section. The
upper ends of apertures H are frustro-conical as indicated at l5. This frustro-conical shape facilitates the passage of liquid into the through apertures M. Fig. 4 indicates that the angle of frustro-conical portion I5 is degrees. Although this is the preferred angle, other angles could be used. 7
- A disc valve is located at the lower end of the piston. This valve includes disc l6. Nut [3 has a reduced portion [1. Reduced portion 11 passes through an aperture in disc l6. Reduced portion I! is longer than the thickness of disc IE, to permit disc It to move relative to the piston. When the piston is moving downward, the disc 13 will be against piston II and apertures M will be closed. When piston II. is moving upward disc 15 will be spaced from the end of the piston permitting liquid to pass through apertures l4, around the edges of disc l6, into the space below the piston.
The cylinder 3 has slotted apertures l8. As indicated in Fig. 4 these apertures [8 are above the piston when the piston is near or at the lowest position of the piston. The reasons for these slots will be discussed further hereinafter.
Radial arms I9, 20 and 2|, are secured to the upper end of reservoir 2. The center portion of these arms has an aperture for the passage of the piston rod. Post 22 is secured to radial arm 20 in any suitable way. The upper end of post 22 is received in the bifurcated end of lever 23. Pivot pin 24 passes through the end of post 22 and lever 23. The upper end of the piston rod, indicated as 25, is pivoted to the lever 23. Pivot pin '26 interconnects the upper end 25 of the piston rod and the lever 23. Coil spring 21 tends to keep lever 23, the piston rod I2, 25 and 28 and piston l l, in raised position.
Since lever 23 is limited in its movement in one direction by contact with reservoir 2, the quantity of liquid dispensed in one operation can be varied by varying the length of the piston rod. The piston rod is made in three parts, I2, 25 and 28. Part 28 is a tube having its ends in threaded engagement with the threaded ends of rods l2 and 25 as indicated at 29 and 30 of Fig. 1. One thread 29and 30 is right-hand and the other thread is left-hand, so that the length of the piston rod can be changed by turning sleeve 28. The dispenser I has a handle 3| located below the end of lever 23 so that lever 23 and the handle 3| can be grasped by the same hand.
In operation, the parts will normally be in the relative positions of Fig. l and there will be liquid 3 in reservoir 2, as indicated at 32. To dispense liquid, lever 23 is pushed down. If there is liquid below piston I I, some of this liquid will be forced through nozzle 4 as the piston H moves down.
As piston H moves down, liquid is drawn into the upper portion of the cylinder through valve 1. As the piston approaches the end of the downward motion of the piston, slotted apertures 18 are uncovered and liquid can enter the cylinder through apertures l8. Apertures [8 can be eliminated if desired, When the pressure on lever 23 is released, spring 21 will move lever 23, the piston rod and piston to their upper position. As piston I I moves upward, valves 1 close and liquid is forced through apertures l4 and around the edges of disc l6, into the lower portion of the cylinder. The dispenser is now ready to dispense another quantity of liquid.
In practice, I have found that the form of my invention illustrated in the drawings and described in the above description is the most efficient and practical. Various minor changes in details of construction, proportions and arrangement of the various parts may be resorted to without departing from the scope of the invention as set forth in the following claim.
A device of the character described comprising a reservoir, a vertically extending hollow cylinder aflixed in the lower end of said reservoir and extending downwardly therefrom, an apertured nozzle aifixed to the lower end of said cylinder, a head aflixed in the upper end of said cylinder, a plurality of one-way inlet valves mounted in said head, a piston vertically reciprocable in said cylinder, a one-way valve permitting liquid to pass through said piston from the top to the bottom thereof, a lever pivoted to the top of the reservoir for movement in a'vertical plane, and a piston rod interconnecting said piston and said lever, said cylinder having a plurality of circumferentially extending apertures formed therein approximately midway between said head and said nozzle.
