SIB/UP PUMP.

Application filed February 4, 1922. Serial No. 534,130.

To all whom it may concern:

Be it known that I, VVILLIAM Mormon, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in a Sirup Pump, of which the following is a specification. I

My invention relates to new and useful improvements in a sirup pump, and has for its object to provide a device of this character for dispensing liquids in predetermined quantities so constructed as to be compact, strong and durable, noiseless in operation,

having no complicated parts to bind, clog or get out of order and which will be absolutely sanitary and very easy to clean and maintain in a cleanly condition.

Another object of my invention is to pro vide in combination, a valved sirup cup, a cap provided with a spout and a sirup tube connecting the cup and cover and acting as a single support therefor, said sirup tube having feet so associated with said tube and the cup as to thoroughly brace the parts andv prevent the likelihood of the cup being broken from the sirup tube or forced out of proper alignment.

Another object of the invention is to pro vide in combination with a valved cup, a plunger having an outlet notch in the edge thereof whereby any liquid within the cup may be poured therefrom when the pump is removed from a jar.

# A further object of the invention is to provide means for throwing the plunger rod and its yoke out of alignment should the plunger and its rod be wrongly positioned when being assembled.

A still further object of the invention is to provide an improved means for regulating the movement of the plunger rod and the plunger carried thereby in order to regulate the quantity of liquid to be dispensed and to provide means for absolutely holding the parts in their adjusted positions.

Other objects of the invention are to provide for limiting the upward or outward movement of the plunger, to provide for housing the spring in order that the liquid or foreign substances cannot reach the same and to so connect the parts that they may be readily disassembled when necessary without the use 'of tools,

l/Vith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1, is a side elevation of a sirup pump made in accordance with my invention.

Fig. 2, is a plan or upper-end view thereof.

Fig. 3, is an enlarged fragmentary side elevation of the upper portion of the pump with parts broken away and shown in section to clearly illustrate certain details of construction. a

Fig. 4, is a similar view at right angles to the view illustrated in Fig. 3, some of the parts being broken away and shown in section to illustrate other details of construc,

tion.

Fig. 5, is a face view of the adjustable lock nut.

F ig. 6, is a section at the line 6--6 of Fig. 4: with the parts below this line with the exception of the lock nut, being eliminated.

Fig. 7, is an enlarged sectional view at the line 7-7 of Fig. 1.

Fig. 8, is an enlarged vertical section of the sirup cup and adjacent parts at the line 8-8 of Fig. 7 with some of the parts illustrated in elevation.

In carrying out my inventionas here embodied, 2 represents a cup generally termed in the trade as a sirup cup, to the lower end of which is detachably connected a bottom 3 having threaded connection with the said cup and this bottom has an inlet opening 4 controlled by the vertically movable valve disc 5 which has a post 6 passing through the hub 7 and which is a part of a spider disposed across opening 4:, the said post being headed as at 8 to prevent the ac cidental displacement of the valve disc. With the upper end of the cup 2 is formed the bracket 9 preferably consisting of three legs 10, 11 and 12 and an integral boss 13 having a recess 14 in communication with a channel 15 formed in one of the legs, as 12, of the bracket and through .theeXte-nsion 16 of the leg 12 the lower end of said channel communicating with the interior of the cup 2 through an opening or duct 17 through the walls of said cup. The lower portions of the legs of the bracket have notches 18 which produce shoulders 19 to act as stops for limiting the outward movement of the pump plunger as will be hereinafter described.

The boss 13 is offset from the vertical center of the cup 2 as plainly shown in Fig. 1 an'din this boss is fixed the lower end of the tube 20, the upper end of which communicates with tne spout 21 carried by the flanged cov .r 22 said cover having a'hole 23 therethrough which is oifset from the center of the cup and cover diametrically opposite the tube 20.

' In the cup 2 is mounted for vertical movement a plunger 24: having a notch 25 in one edge which when the plunger is in its uppermost position and in contact with the shoulders 19 a portion of said notch projects above the upper edge of the side walls of the cup so as to form an outlet from said cup permitting the contents of said cup to be poured therefrom when the same is tilted the proper (:listance or in other words partially inverted. To this plunger is fixed in any suitable and well known manner a piston rod 26 which lies in close proximity to the outer surface of the boss 18 where it passes said b'oss'and this piston rod parallels the tube 20, as plainly shown in Eig. 1. To'the upper endiot the piston rod 26 i secured a yoke 27 having an internally threaded hub 28 into which threaded the lower end of the handle 29 provided with a spring chamber 30jand said lower end of the handle 29 is beveled as at 31 so as to form a. flaring mouth whi'chwill freely pass over a coact-ing part to be later described.

As the arms or uprights of the yoke 27 are in vertical alignment with. the handle 29, as shown in Fig. 1, and as the piston rod 26 is out of line with said p'arts'th'e lower hub 32 oi' the yoke is offset or out of vertical alignment with the arms or u rights of {I i.

said yoke so as to properly align with the piston rod and when the parts are assembled said lower hub 32 lies inclose proximity to the tube 20thus preventing the piston rod from being bent out of line to any great extent or otherwise damaged should the pump be grasped by means of the tube 20. Vi ith the upper end or the yoke or the upper hub thereof is formed an enlargement 33 which projects away from the tube 20 after" the parts have been assembled and said enlargement is oflsuflicient size that should an attemptbe made .to installthe piston rod and its component parts in the -wrong position said enlargement will. contact with the'tube 20 and prevent the upper hub 285 mm being moved ihto aliigii-rnent wanes hn'le23 movement of the parts in one Clll 'ing outward a slig on the spring casing.

1 ,esoper through the cover an thus prevent the improper assembling of the parts.

The spring casing 34; externally thread ed and provided with a wedge shaped end 35 for registration with a V shapeo. soc en 36 in a projection or lug 37 carried by the upper portion of the tube 20 and when the wedge shaped end of said spring casing is in the socket said casing will be prevented from rotating. The spring casing an is provided with a chamber 38 and the upper end of this spring chamber beveled from its inner face outwardly as at 39 so as to form a daring mouth to prevent the spring 40 catching on the edge of said spring casing, the said spring being housed in the chamber 88 in the spring casing and the chamber 30 in the handle 29 so as to normally force said elements apart and as the spring casing is stationary or rests upon the projection 37 said spring will normally force the handle 29 upward or outward. The handle 29 telescopes over the spring casing 34 as plainly shown in Fig. 3 and the beveled ene 31 of th'e'handle 29 prevents it from engaging or biting into the exterior threads of the spring casing as will be obvious.

On the spring casing is adjustably mounted the regulating nut 41 in the form of a notched'ring, the notches 42 thereof adapted to register with the upper end of the tube 20, as plainly shown in Fig. 6, to prevent rotation of said nut after being properly adjusted. This regulating nut 'ulates the ection or downward so as to regulate the amount or liquid forced from the cup through the tube '20 and out of the spout 21 and this regulation has a range from Zero to two ounces in liquid measurement. The. regulation is accomplished as follows;-

y forcing the casing 34 upward against the action of the spring 40 so as to remove the wedge end of said casing from the socket 36 and throwing the lower end oi, said casht distance the regulating nut'will be disengaged from the tube 20 so that it may be rotated to run it up or down 7 After the proper justment has been obtained the spring casing is replaced so that the wedged end enters the socket 36. By pressing downward upon the handle 29 the yoke. the piston rod and piston will be likewise forced down ward the distance between the lower face of the upper hub 28 of the yolce 27 and the regulating nut 41 with which said upper hub ottheyoke contactsandtheretore it Lox will be obvious that the position of said regulating nut uponthe spring casing will regulate the-movement or the piston 2 to gage or regulate "thequantity of liquid forced from the cup 2an'd when the regulatingnut. has been adjusted it cannot be accidentally moved out adjustment be
