Specification of Letters Patent.
Patented Jan. 14, 1919.
Application led January 27, 1917. Serial No. 144.832.
To r/Z? 'whom it ma concern.'
Be it known t at I, ADoLPH ECKERT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented'new and useful Improvements in Syrup-Pumps, of which the following is a specification.
Syrup pumps of the class to which my invention relates are used more particularly in connection with soda fountains and other means for dispensing beverages in which there is a series of jars containing avoring In/atters from which it is desired contents in any definite quantities for the purpose of ilavoring drinks. My invention relates more particularly to .a means b which the stroke of the pump may be so adjusted as to discharge any desired quantity of flavori'ng liquid at each stroke 'of the piston.
In the accompanying drawings I have shown and in the following s ecieation described my preferred form o the invention but it will be understood that the specific disclosure is for the purpose of exemplifiea-l tion only and that the scope of the invention is defined in the following claims in which I have endeavored to distinguish it from the" prior art, so far as own to me, without, however, relinquishing or abandoning any portion or feature thereof.
Referring to the drawing Figure l is an elevation, partly in section and broken away, of a syrup tank having my improved syrup pump applied thereto; Fig. 2 is a central vertical section of the upper end of the same on an enlarged scale, parts being shown in elevation; Fig. 3 is a perspective of a detail; and Fig. 4 a horizontal section on the line 4-4 of Fig. 2, looking in the direction of the arrows.
`The tank 5 may be of any usual or preferred form and at its upper end is formed with an upwardly projectmg flange 6 about which a cover 7 attached to the pump and formed with a downwardly projecting flange 8 fits. The pump cylinder 9 is attached to and supported from said cover 7 bymeans of a post 10 secured at its opposite ends to said cover and cylinder, respectively, and a pipe 11 which also forms the outlet or connection from the pump cylinder to the nozzle 12. At its lower end the pipe 11 isv soldered or otherwise secured in an oifset chamber 13 of the pump cylinder. 9 and at its upper end it may be similarly secured at 14 in an enlarged bore 15 of the nozzle.
e latter projects through the cover 7 being formed on the upper side thereof with a fiange 16 and screw-threaded at its inner end 17 to receive a nut 18. Th ner of this connection, however, is immaterial for the -present purpose. The plunger or piston 20 tits somewhat loosely within the cylinder 9 and is guided therein but in its normal position is located, as shown in Fig. l, between upward extensions 21 of the wall of the cylinder leaving apertures 22 between said piston and said wall through which the syrup or Havering liquid can enter the chamber of the pump. The `piston is with a piston rod 23 which is tubular 1n the plug carries a head or finger-piece 25 Iby means of which the piston rod and piston are depressed.
The head is shown by reducin the upper end of the latter forming a s oulder at 26 against which the head is ressed by a screw 27. The form of the head) is immaterial but is shown as comprising a threaded annulus 28 having an inturned flange-and screwed at 29 upon the body of the head a celluloid or other plate 30 which may contain the name of the syrup to be dispensed by the pump, being maintained in position on said head by the annulus. In order to limit and adjust the length of stroke of the plunger a sleeve 31 is secured to the cover 7 concentric with and surrounding the plunger rod or tube 23 which, at its upper end, is reduced as at 32 forming a shoulder 33 which abuts against the lower end of the sleeve 31 and limits the upward movement of the plunger. A secondsleeve 34, the diameter of larged at 35, has a sliding tit within sleeve 31 and is adjustably secured to the piston rod with which it reciprocates. At its upper end sleeve 34 is formed with an inwardly-extending flange 36 which closely embraces the plug 24 but is adjustable longitudinally thereof, said plug being attened on its opposite sides as'at 37, 37, Fig. 4, where it is engaged by the Bange of the sleeve so that said sleeve is prevented from rotation with reference to said plug. The upper end of the sleeve 34 is slightly enlarged and provided wlth an exterior screw thread at 38 which is e precise man--` as secured to the plug which is slightly enengaged by an interior thread upon an adjusting nut 39 revolubly mounted upon the lug 24. Obviously the sleeve 34, being movable longitudinally of the plug but held from rotation with respect thereto, by rotating the adjusting nut 39 said sleeve can be raised and lowered or axially adjusted relative to said plug and piston rod.Y 'The nut 39 is formed at its upper end with a transverse groove 40 which receives a transverse rib l upon the head 25 and a spring 42 is inter- 34 and the bottom of the sleeve 31 upon the cover and normally and .yieldingly maintains the piston rodl andpiston in upper position and the adjusting nut against the under face of the head '25. I When the piston is depressed against the resistance of spring 42 by pressure ofl the hand upon the head 25 the liquid in the` pump .cylinder or chamber is ejecteduntil the downward movement of the piston is stopped which occurs when the lower end of the lower end ofbthe stationary sleeve 3l. By adjusting the sleeve 34 obviously the amount of liquid discharged at each stroke of the piston may be varied.
adjusting the sleeve vertically relative thereto and in practice the revolution of the nut is terminated with the groove in the upper face thereof in register with the rib on the lower face of the head so that the nut is yieldingly held against further rotation. Thus when the stroke of the piston has 'been suitably adjusted it cannot be accidentally changed.
I claim: 1. In a syrup pump and in combination with the cover, cylinder, spout, piston and piston rod thereof, a sleeve mounted upon the cover and surrounding the piston rod, a second sleeve longitudinally adjustable 'relative to said piston rod and sliding Within the sleeve on the cover, a spring within said sleeves,
posed between the upper flange on the sleeve the sleeve 34 engages the inturned flange on..
This adjustment is made by turningthe adjusting nut 39 thus means for reventing relative rotation be-l tween the s eeve on the piston rod and said piston rod, an adjusting nut revolubly mounted on the piston rod and having a thread engaging a thread upon the adjustable sleeve, and interlocking devices between the piston rod and the adjusting nut to prevent accidental revolution of the latter.
2. In a syrup pump, and in combination with the cylinder, spout, piston and pistonrod thereof, an abutment rigidly connected to the cylinder and surrounding the piston rod, a sleeve of larger diameter than the piston rod and reciprocable relative to the same, a spring .within the sleeve and intermediate the same and the abutment, a knob on the end of the piston rod, a thimble 39 rotatably journaled upon the rod directly beneath the knob and having a screw engagement with said sleeve, inter oeking surfaces on the knob and thimble, respectively, the 'construction being such that the pressure of the spring normally holds the thimble against the knob maintaining the interlocking members in engagement and thereb preventing accidental rotation of the thim le.
3. In a device of the class described, and in combination with the cover, cylinder, spout, piston and piston-rod thereof, a depending sleeve mounted on the cover and uiding the piston rod, a sleeve longitudinal y movable upon the rod but held from rotation with respect thereto, the lower end of the latter sleeve extendinglinto and being guided by the first-mentioned sleeve, a spring within the sleeves and tending' to force them apart, a knob on the rod having a transverse rlb on its under surface, a t 'mble mounted for rotation With respect to the rod having a 8 threaded engagement with the sleeve on said rod, and a transverse groove on its upper surface with which therib on the knob coacts, the construction .being such that the sprind holds the thimble in yielding inter- 9 locked engagement with the knob.
