SIR'UP PUMP.
Application led January 2, 1925. Serial No. 18.
T o aZZ whom t may concern.'
Be it known that we, CHARLES L. BASTIAN and CARL G. JOHNSON, citizens of the United States, residing at Chicago, in the county of Cook and fit-ate of Illinois, have invented certain new and useful Improvements in Sirup Pumps, of which the following is a specification. l
This invention relates to a novel and improved sirup pump and has for its principal object to provide such apump which will permit ready adjustment, so as to vary the amount of sirup fed at `each operation thereof. f y
Another object isto provide an adjusting means which may be readily applied to existing Sirup pumps with a minimum of alterations therein v A still further Objectis to provide an adjusting means for sirup pumps which cannot be accidentally Operated.
In the accompanying drawings in which we have shown a selective embodiment of our invention.
Fig. 1 is an elevation of a sirup pump embodying my invention.
Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3U Fig. 2.
Fig. 4 is asectionon the line 4 4 of Fig. 2. f
Referring now to the drawings:
The numeral 1 designates the top plate of a sirup pump, this plate supporting a cap 2 having a spout 3 through which the Sirup is delivered. The pump further comprises a Sirup cup 4 from which sirup is pumped to the spout 3 through the sirup tube 5. Also connecting the sirup cup 4 and top plate 1 is a support rod 6.
The sirup is forced from the cup 4 by means of a plunger 7, provided with a stem 8 slidably mounted in a housing 9 carried by the top plate 1, the plunger being guided in its vertical movement by engagement with the Sirup tube 5, as is well known in the art. The upper end of the stem 8 is provided with the usual knob 10, having a suitable label 11.
Upward movement of the plunger 7 is limited by engagement with the bottom of the support rod and a lug 12 on the Sirup tube. The amount of sirup to be fed evidently will be governed by the extent of 3 is a section on the line 3-3 of the downward movement of the plunger, and it is to means for adjusting the downward movement of the plunger that our invention relates.
As plainly shown in Fig. 2 the upper end of Stem 8 :is reduced to form a shoulder 13 thereon, the reduced portion 14 being threaded for engagement with a threaded sleeve 15. It will be evident that the downward movement of the threaded sleeve 15 will be limited by engagement wit-h thev shoulder 13. The threaded sleeve 15 is provided with a longitudinal key 16 sliding in va groove 17 in a sleeve 18 surrounding the threaded sleeve 15 and movable vertically in the cap 2, said vertical movement normally being prevented by a coiled spring 19, having one end engaging the bottom of the housing 9 and the other engaging a shoulder 2O at the upper end of a recess 21 in the sleeve 18. The upper end of the stem 8 is again reduced as at 22 to receive the knob 10 thereon, said knob being secured in place as by a nut 28. The knob 1() is provided with a downwardly extending boss 24 fitting in a corresponding recess in the sleeve 18 and having a shoulder 25 engaging a projection 26 in said sleeve. The boss 24 is reduced at its lower cud as at 27 and this portion is provided with a flattened face 28 to engage a correspondingly flattened portion 29 of the sleeve 18 for a purpose which will presently appear.
In the operation of the device described above the knob is pressed to cause vertical movement of the plunger, this vertical movement being limited by engagement of the lower end of the threaded sleeve 15 with the bottom of the housing. When it is desired to vary the .amount of sirup to be fed, the sleeve 18 is depressed against the action of the spring 19 so as to release the surfaces 28 and 29 from engagement with oney another. During this movement the key 16 will slide lin the groove 17 so that the sleeves 15 and 18 will be held against relative rotative movement. After the surfaces 28 and 29 are out of engagement, the sleeve 18 can be rotated, a knurled surface 30 being provided for that purpose. Rotation of the sleeve 18 will result in rotation of the threaded sleeve 15 therewith, thus causing longitudinal movement of the same relative to the plunger stem. When the required adjustment has been made, release of the parts will cause them to return to the position shown in F ig. 2, under the action ofthe spring 19, this being the spring which normally holds the plu-nger in its uppermost position.
To prevent accidental rotation of the sleeve 18, which rotation will result in the adjustment of the threaded sleeve 15, the flattened surfaces 28 and 29 are provided. By this means rotation of the sleeve 18 accidentally as by coming in contact with various articles, is prevented. Rotation cannot be accomplishd without first moving the sleeve 18 longitudinally of the plunger' stem so as to release the surfaces 28 and 29 from engagement with each other. It will also be noted that the key 16 will always be in engagement with the groove 17, the length of the threaded sleeve 15 being such as to insure this engagement, even when it is adjusted to its lowermost position.
From the above it will be seen that we have provided a sirup pump which may be readily adjusted so as to vary the amount of sirup to be fed. These sirup pumps are usually arranged in a battery behind a counter, and in a position where an attractive appearance is essential. @ur invention insures that the attractive appearance shall be maintained, because of the fact that the rotation of the sleeve 18 causes a longitudinal movement of a part which is concealed thereby, thus avoiding having an adjusting means which would cause longitudinal movement of the knob and sleeve relative to each other. In otherl words, the top of the knob is always at the same elevation when the pump is not being operated. lVhile we have shown our invention as embodied in a sirup pump, nevertheless, we do not desire to be restricted thereto, but intend to claim our invention for use in any pump where it may be of use.
lVe are aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the invention and we reserve the right to make all such changes as fairly fall within the scope of the following claims.
l/Ve claim:
1. A pump comprising a plunger having a stem, a sleeve threaded on one end thereof, a second sleeve surrounding said threaded sleevevand rotatable therewith but capable of longitudinal movement relative thereto, means engaging said second sleeve and resiliently urging it longitudinally of said plunger stem, and means secured to said stem and engaging said sleeve to prevent said longitudinal movement.
2. A pump comprising a yplunger having a stem, a threaded sleeve on one end of said stem, a second sleeve mounted to rotate with said threaded sleeve but movable longitudinally thereof, a knob secured to the end of said stem and engaging said second sleeve, and means resiliently urging said second sleeve into engagement with said knob.
3. A pump comprising a plunger having a stem, a sleeve surrounding said stem, means preventing relative rotation between said stem and sleeve, means resiliently urging said sleeve into position wherein said rotation preventing means is effective and a sleeve threaded on said stem and movable longitudinally of said first named sleeve but rotatable therewith.
4. A pump comprising a plunger having a stem, a sleeve surrounding said stem, means on said stem and on said sleeve preventing relative rotation therebetween, resilient means urging said rotation prevent` ing means into engagement, a sleeve threaded on said stem and capable of longitudinal movement in respect to said first named sleeve but rotatable therewith, and means adapted to engage said threaded sleeve to limit movement of said stem.
