T all whom it may concern:
Be it known that we, donN KosiLiN and MARciN GRZESlK, citizens, respectively, of the United States and Poland, residing at Broolc lyn, in the county oi? Kings and State of New York, have invented certain new and useful Improvements in Liquid-Dispensing Pumps, of which the following is a specification.
This invention relates to improvements in dispensing apparatus and has for its principal object to provide a device which is particularly adapted for :use in dispensing condensed milk, syrup and similar viscous substances which are more or less free running.
Another object of the invention is to provide a device which will eliminate the disagreeable features usually accompanying the serving and handling of such sticky substances as molasses, condensed milk, syrup, honey and the like and which is so designed that the fluid may be removed from its contamer without necessitating the lifting or tilting of the same.
1th these and other ob ects in view the invention consists in the novel construction,
combination and arrangement of parts which will be fully set forth in the following speci fication, claimed and illustrated in the ac-.
companying drawing, in which,
Figure 1 is a front view of this improvedv dispensing apparatus,
Figure 2 is aside view of Figure 1,
Figure 3 is a rear view oi? the device on a slightly enlarged scale,
Figure l is a horizontal sectional view through the cylinder,
Figure 5 is a slightly enlarged sectional view taken on line 55 of Figure 2,
Figure 6 isa fragmentary side view oil? the discharge nozzle and valve therefor,
lligure 7 .is an enlarged trout view of the device illustrating the same inserted in .a can and showing port-ions broken away to more clearly illustrate the details of construction,
Figure 8 isa side view oi the intake valve showing portions in section,
Figure 9 is an enlarged detail sectional view of one of the discharge valves,
Figure 10 is a perspective view of one of the valves.
Figure 11 is a perspective view, partially in section, showing the valve details.
Referring to the drawings in detail the numeral 15 designates the discharge .tube of the device which is provided at its lower end with a tapered portion 16 and at its upper end with an arcuate discharge spout 17' provided at its lower discharge end with an inwardly extending flange 18 which forms a seat over which the valve 19 slides. A slot 20 is formed in the rear wall of the nozzle 17 immediately above the upper side of the flange 18 to accommodate the valve 19 and a rearwardly extending tongue 21 is formed on the nozzle immediately above the slot.
In order to hold the valve in closed position a retractile coil spring 22 has one end connected to the tongue '21 while its opposite end is connected to a-link 23 which is connected at one end to the valve 19 and at its opposite end to an operating lever 2 1 which is pivoted as at 25 to the spout 17.
A cylinder 26 issecured to the discharge tube 15'a-nd is separated by the tube into two separate cylindrical chambers 27 in which pistons 28 are mounted to reciprocate. These pistons are mounted on the inner ends of piston rods 29, the outer ends of which are secured to the angular extensions 30 formed at the outer ends of theguide rods 31, which are arranged in planes parallel to the piston rods and are operable through guides 32 mounted adjacent opposite ends of the cylinder. As shown in Figures 3 and at a grooved guide member 33 is secured to the rear side ot the cylinder in which the guide rods 31 slide and formed at the extreme inner end of each guide rod is a thumb piece 3% by means of which the device is operated. Compression coil springs 35 surround the piston rods 29 and are arranged between the cylinder heads and the members 30 so that the pistons will be y-ieldably held adjacent the outer ends of the cylindrical chambers 27.
Formed, in the discharge tube at opposite sides thereof are passages 36, the lower ends oi which open outwardly as shown in Figure '7 to admit air under pressure into the can, while the opposite end of the passages open into the chambers, 37 formed at the inner ends of the cylindrical chambers 27 by means of the valve members designed generically by the numeral 38.
These valve members are best illustrated in Figure 9 and each consists .ofa cylindrical body 39 provided with a longitudinal bore 10 which opens into an enlarged bore 4E1. A valve seat is formed at the point where the bores meet and cooperating therewith is a spring actuated check valve 42 the stem of which is slidably mounted in the cage 43. Surrounding the cylindrical body is a plug 44 of soft yieldable material such as rubber, the outside of which is adapted to tightly fit within the cylindrical chambers 27.
Formed in the wall of each chamber adjacent the valve member 38 is an opening to which is connected a by-pass 45, which leads to a longitudinal bore 46 formed in one end of a valve body 47. As shown, one end of the bore 46 opens into an enlarged bore in the body and at the junction of said bores a valve seat is formed with which the spring actuated check valve 48 cooperates to close the passage. A valve cage 49 is mounted at the open end of the passage and is provided with a guide opening through which the stem of the valve 48 is operable. An angular extension 50 is formed at the outer end of the valve stem and projects through an opening formed in the projecting end of a plate 51, which is slidable in a dove tail groove formed in the rear side of the valve body 47 Slidably mounted in the opposite end of the groove is a valve actuating member 52, the outer end of which projects beyond the valve body 47 and is provided with an up Wardly extending tongue 53, the upper end of which is adapted to be engaged by one of the guide rods 31 to open the valve during the outward movement of the pistons to cause the valve to be forcibly closed upon the completion of the out stroke. In order that the movement above referred to may be transmitted to the valve actuating plate 51, a yieldable connection, such as the coil spring 54, is connected to the pin which extends outwardly from the inner end of the valve actuating member and the opposite end of said spring is connected through a securing means 56 formed adjacent the inner end of the plate 51.
Pivotally mounted at 57 on the rear side of the cylinder is an oscillating lever 58 which is provided at its upper and lower ends with slots, the lowermost of which re ceives the pin 55 while the uppermost slot receives a pin 59 carried by a block 60 which is slidably mounted in the grooved guide 33, in such a manner that when the thumb pieces 34 are moved inwardly to the limit of the piston stroke, the end of one of the guide rods 31 will engage the block and shift the lever in such a manner as to open the valve 48 so as to permit the free entrance of air to the cylindrical chambers 27 during the return stroke of the pistons.
In order to hold the device in position on a can, a collar 61 is fitted over the discharge tube and is held in various adjusted positions thereon by means of a set screw 62. EX- tending laterally from the collar 61 are bifurcated arms 63 in the outer ends of which are pivotally mounted levers 64- upon the lower ends of which are formed retaining hooks 65, adapted to engage under the flange of the can top. A sleeve 66 is slidably mounted on the discharge tube 15 between the can top and the collar 61 and the under side of the sleeve is provided with a gasket 67 which is pressed firmly against the can top by means of a compression coil spring 68 to form a seal which will effectively prevent the escape of air from the can around the tube.
In operation the device is placed in position on the can as shown with the hooks engaged under the flange of the can top so that the gasket will provide an effective seal around the discharge tube. \Vhen in this position the set screw 62 may be loosened to permit the tube 15 to be adjusted to proper position with its lower end in close proximity to the bottom of the can. Upon gripping the thumb pieces 34 between the thumb and forefinger it will be obvious that the pistons will move inwardly in such a manner that the air contained in the chambers 27 will be forced through the passage 40 of the valve member 38 and cause the valve to open so that the air passes under pressure into the chambers 37 and thence down the passages 36 into the, can where it rises above the surface of the liquid and creates a pressure on the top thereof so that the liquid will be forced up wardly through the discharge tube and into the discharge nozzle. It will be readily seen that the flow of the liquid from the discharge nozzle may be controlled by'the manipulation of the valve 19 which cooperates with the flange 18 in providing an effective cut-off for the liquid thereby preventing the undesirable drip usually accompanying the dispensing of a thick viscous liquid. Before releasing the thumb pieces it will be seen. that they will return to original position under the influence of the springs 35 and owing to the engagement of one of the thumb pieces with the sliding block 60 the valve 4-8 will be opened to admit fresh air to the chambers 27 through by-passes 45 so as to prepare the device for a repeat operation. In order that the bypass valve 48 will remain inopen position until the return stroke is completed leaf spring 69 is secured to a yoke 70 in such a manner that it will frictionally hold the valve actuating member 52 against longitudinal movement until the hook 53 at the end thereof is engaged by the shoulder 71 formed on one of the guide rods 31.
While in the foregoing there has been shown and described the preferred form of this invention it is to be understood that minor changes in the details of construction,
combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
l/Vhat is claimed is 1. A liquid dispensing pump comprising a hollow Stem curved semi-circularly in its upper portion, its lower straight portion be ing enterable into a container, means for securing said stem to the walls of the container, a gate valve at the extremity of said curved portion, a casing circumjacent said lower portion, said casing terminating at a point above the end of the lower portion, an air pump arranged transversely of said stem, said pump delivering air to the space between said stem and said casing, and means whereby said pump may be manually operated.
2. A liquid dispensing pump comprising a hollow stem curved semi-circularly in its upper portion, its lower straight portion being enterable into a container, means for securing said stem to the walls of the container, said lower portion being reduced in diameter, a casing spaced from said lower portion, means for adjustably engaging said stem with the body of the container,
a double acting hand pump on said stem' communicating with the space within said casing whereby air may be entered into the container, and means for closing the end of the curved portion of said stem.
In witness whereof we afliX our signatures.
