SYRUP-PUMP.

Specification of Letters Patent.

Application led December 18, 1909. Serial No. 533,943.

of Cleveland, county of Cuyahoga,'and StateV of Ohio, have invented a ne and useful lmprovement in Syrup-Pump of which the the principle. of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

M f invention relates to pumps4 and has )articular relation to that class of pumps which is used in soda fountains for pumping syrup kfrom a suitable tank into a glass 'or similar receptacle. AThe objects of the invention are the rovision of a pump of more simple and e ective operation than pumps of this class now on the market, to render the pump more ,easily cleaned, and tomake it adjustable so that it may be adapted for use in varying conditions.

To the accomplishment of these and related ends said invention, then, consists of the means hereinafter described, and particularly pointed out in the claims. y

The annexed drawing and the following description set forth in detail certain mechanisms embodying the invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principle of the invention may be used.

In said annexed, drawing Figure 1 is a side elevation of a pump embodying my invention, the tank being diagrammatically shown; Fig. 2 is a vertical section thereof; Fio'. 3 is a section of a detail, showing an adpistable part in a diiierent position than in the other figures.

lt will be understood that pumps `of this class are generally attached to a removable cover of a containingtank. Such a tank A is shown diagrammatically in the drawings, while the removable cover is designated by reference letter a. Suspended afrom the cover a is a cylinder B which has in its bottom a hole covered by a disk capable of limited upward movement, the hole and disk thus Jforming a valve through which the contents of the tank may be admitted into the cylinder of the pump. A discharge tube b leads from` the cylinder and is attached to the cover a, while above the cover it is connected with a discharge nozzle b2; it is this land engage the groove o8.

discharge tube b which serves to sus end the cylinder B from the cover a and in xed relation thereto. A piston b reciprocates in the cylinder .13,

- and attached to the piston is a two-part plston rod, the parts of which are designated 1n the drawings by the letters o and o. The part c has near its upper end an annular groove @Sand over this end of the part fits a sleeve c2 1n which is an aperture which registers with the groove c3, so that a set screw o4r may project through this aperture The part c is screwed into the uoper end of the sleeve c2. The discharge nozzle b2 is formed with a laterally extending plate D which extends partly over the cover a; the plate D is formed on its under side with a. boss whichextends downwardly through an opening in' the cover a, the plate beingsecured firmly against the cover by a lock nut d which engages the boss below the cover. The plate D and its boss are formedv with a Icentral opening and into this opening, above the cover a, is screwed a sleeve d which forms a bearing for the upper part c of the pistonrod. A knob E, attached to the upper end of part c', forms a handle for o erating such part. This knob E is provide with a depending interiorly threaded fiange, and engaging the interior thread of such flange is a sleeve e which has a bearing surface On sleeve d.. The spring e encircles the upper portion of the rod within the several sleeves, its ends respectively abutting against a shoulder formed in knob E and a shoulder formed in the boss of plate D, and this spring serves to normally retain the rod in its uppermost position.

The several advantages of my improved device may be readily understood from the drawings and the detailed description.

The spring constantly tends to raise the piston, and the upward movement of the piston is limited by contact of sleeve c2 with lock nut d. The length of stroke of the piston may be varied at will, however, by varying the limit of its downward stroke. This may be easily and quickly eected by screwing-the sleeve e a greater or less distance into the flange of knob E. The sleeve strikes the plate D when the rod is depressed so that the late D thus is in e`ect a shoulder adapted) to limit the downward stroke of the piston. This adjustability of the PatentedAug. 16, 1910.

y stroke highly advantageous in the practical' use of the pump, for` by varying the stroke in this manner, amount of syrup may be dispensed by a single stroke, as described.

A u'rther advantage of my complete pump exists in the provision of a two-part piston rod. By loosening the set screw, the part of the piston rod below the cover, together withl its attached piston may be quickly removed from the device so that the cylinder andJ the piston may be thorou hly cleansed.

ther modes of applying the principle of my invention may employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any ofthe following claims or the equivalent of such stated means `be employed.

f I therefore4 particularly point out and distinctlyl claim as my invention 1. A pump of the class described, comprising'a supporting plate, a cylinder supported be ow the plate, a piston reciprocable therein, a fixed tubular member supported by said plate, a piston rod extending through the plate and said member, a knob secured to said rod, a fixed shoulder encircling the rod, a sleeve screwed to said knob and adapted to engage said shoulder, said sleeve having a spring tending to move the rod, said spring being inclosed by said sleeve and member.

2. A pump of the class described, comprising a supporting plate, a cylinder supported below the plate, a piston reciprocable therein, a I'ixed tubular member extending up- .wardly from the plate, a piston rod extendobsecured to the upper `end of the rod, a xed annular shoulder encircling the rod, a sleeve screwed tosaid knob and adapted to engage said shoulder, said sleeve having a bearing on said member, and a spring tending to move the rod, said spring being inclosed by said sleeve and member.

B. A pump of the class described, lcomprismg a supportmg plate, a cylinder supported below the plate, a piston reciprocable therein, a fixed tubular member extending u wardly from the late, a piston rod exten ing through the p ate and member, a hollow knob secured to the upper end of the rod, a lixed annular shoulder encirclin the rod, a sleeve screwed into said knob and adapted to engage said shoulder, said sleeve having a bearing on said member, and a spring tending to move the rod, said spring being inclosed by said sleeve and member.

4. A pump of the class described, comprising a supporting plate, a cylinder supported be ow the plate, a piston reciprocable therein, a fixed tubular member extendin upwardly from the plate, a piston ro extending through the plate and said member, a hollow knob secured to the upper end of the rod, a xed upwardly facing an- Y nular shoulder encircling the rod, a hollow -`sleeve screwed into said knob and adapted,

on depression of the rod, to engage said shoulder, said sleeve having a bearing on said member, and a spring inclosed by the knob and the sleeve and the tubular member and tending to elevate the rod.

5. A pump of the class described, comprising a supporting plate, a tube depending therefrom, a cylinder supported at the lower end of said tube and connected therewith, a piston reciprocable in the cylinder, a rod attached to the piston and provided with an annulafgroove near its upper end, a sleeve 'fitting over such end and provided with an aperture in its side, a screw projecting through the aperture and engaging the groove, and a handled rod secured tov said sleeve and extending through the supporting plate. ,v Signed by me this 14th day of December, 1909.
