DISCHARGING MECHANISM FOR SYRUP OR OTHER JARS.

SPECIFICATION forming part Of Letters Patent No. 642,1 19, dated January 30, 1900.

Application filed April 23,1898. Serial No. 678i663. (No modeLl To all whom, it may concern:

Be it known that 1, Isaac W. IIEYSINGER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have made a certain new and useful Improvement in Diecharging Mechanism for Syrup or other Jars and the Like, of which the tollowingis a full, clear, and exact description, referencebeing had to the drawings which accompany and form a part of this specification, in which- Figure 1 is a vertical section from front to rear through the middle of a syrup-jar em- Figs. 1, 1, and 1 are enlarged views showing slight mechanical modifications in the drip-stops which I prefer to use. Fig. 2 is a horizontal section along the dotted line a: as of Fig. 1 looking downward on the bottom of the jar. Fig. 3 is a transverse vertical section along the dotted line y y of Fig. 1. Fig. 4 is a view, similar to Fig. 1, of the operative parts of my invention, showing a slightly-differentarrangement of the discharge-pipe D and in which a positive instead of a spring thrust causes the retraction of the piston or plunger within the force-chamber. Fig. 5 is a view similar to Fig. 4, in which instead of a push-button merely a lever-handle is used to force down the plunger and retract the same. Fig. 6 is a view similar to Fig. 1, in which instead of a force-chamber of cylindrical form a softrubber hemisphere or the like open beneath is used and a plunger above it to compress the same. Fig. 7 is a view similar to Fig. 1, in which the plunger is made solid and the vent-pipe for the syrup is carried from the force-chamber independently of the plunger and stem; and Fig. 8 shows my invention in which the jar is mounted upon skids instead of having side supports integral with the said jar and in use in a soda-water apparatus.

The lettering in all the figures is uniform. Myinvention relates to mechanism for the discharge of syrups or the like from stationary jars or other receptacles into glasses or other vessels, as is customary in soda-Water apparatus; and it consists in forming the jar or receptacle solid-that is to say, with closed sides and-bottom and without any syrup-vent beneath-and in raising the syrup by pressure above the top of the jar and thence discharging the same into tumblers or the like, as maybe desired; and it consists in provid ing such solidly-walled jar with a recess in the bottom thereof to form a collecting cavity and having preferably sloping sides and providing for this recess an adjustable forcingchamber and plunger so constructed that when slightly raised the syrup will flow into said collecting cavity or recess beneath the sides of said forcing-chamber contained therein, and when the said plunger is forced down contact will be first made between the margins of said chamber and the bottom of said recess, and as the descent of the handle and plunger continues the fluid contained in said chamber will be forced upward through a suitable tube provided therefor and over the upper margin of said syrup or other jarthat is, above the level of the fluid contained therein--and, when the plunger is raised again, that, at the same time the margins of said chamber will be lifted from the bottom of said recess, and the same will refill so long as any fluid remains in said jar.

It will be seen that, in my invention, I use mechanism which will collect into a recess a limited supply of syrup from the jar, and in this l provide a forcing-chamber open below and a pl uuger, so thatI can close thereby connection between the mass of syrup in the said jar and the limited quantity held in said forcing-chamber, and I then force the same by pressure applied to said plunger through a suitable exit-pipe up and over the upper margin of said jar or above the level of the fluid contained therein, the size of the forcingchamber thus graduating the quantity to be forced out at each reciprocation of said plunger, which enables the syrup to bc accurately measured as it is drawn.

Anotheradvantage is that there are no cocks or faucets to become leaky at the bottom of the jar, so as to waste the syrup or else flood the counter with syrup accidentally leaking from an unclosed faucet, while by the use of my invention I am enabled to place my syrupjars down at the bottom of a soda-water apparatus, where they ought to be to receive the full benefit of the ice, and the ice-space is correspondingly enlarged by these jars being I 7 opening A, the whole top of the jar maybe devices in general use.

In the ordinary soda-water apparatus as used in drug-stores, & the front and bottom parts of the interior are absolutely use-.

less, being a mere vacant space beneath the elevated row'of syrup-jars, and this becomes not only a waster of ice, but a source of dampness and dirt. f I

In my invention the row of jars rests practically atthe level of thecounter upon which the apparatus stands, withonly enough space beneath to insure non-conduction of heat.

My invention also relates to devices for preventing drip after a glass of syrup has been drawn and to prevent ingress of insects or dirt to the nozzle thereof.

Referring to, the drawings, A, Fig. 1, is a rectangular jar longer from front to rear,

. though the shape is not material, and constructed ofglass, porcelain-lined metal, or the l a like and having an opening in the top, (shown at A, Fig. 1,) the remainder of the jar having closed walls throughout. Instead of this I left open, of course provided a larger cover be used but I prefer for con venience in handling to haveitin the form shown. A's'shown at B, Figs. 1 and 3, in the forward side of the bottom I form a recess A, preferably circular in form, as shown at Fig. 2,;and withinwardlysloping sides from above downward. The bottom'of the jar A, Figs. 1, 6, and 7, I also. slightly incline forward, so as .to-insure the drainage of the syrup into the recess A when thejar is nearly empty. To support the jar,

byreason of this recess A, I provide it with.

- side extensions B B, by means of which the jar willstand erect or may he slid in or out of its receptacle in a soda-water apparatus. In Fig.

8 instead of these side extensions of the jar I show skids B B, attached'to the syrup-jar holder of the soda-water apparatus, and in this figure I show two of these jars in place, which skids sustain the jars in position therein. When what are called tipping jars are used---that is to say, jars which tip forward a at the top to be filled without removal from the apparatus-I prefer to use-the form of jars shown in Fig.8, but-with the skids B" B replaced by the socketed front support B, as shown in Fig. 5, whereby the jar can be tilted forward at its upper part, so as to expose the top of the, jar and permit the removal of the discharging mechanism and refill the jar while stilljn placein the apparatus, ,the proportions; being suitably conformed thereto, as

' with the present covers oftipping jars.

The opening A, Fig. 3, of the jar A is closed by the detachable cover C, which may be of wood, vulcanite, or metal As shown in Fig.

- 3, it has small flanged lips c c, which'secnre it in place, and, as shown in Fig. 6, it may be circular, if desired, and screwed fast into the opening A the same then being also circular and screw-threaded. Ordinarily I hold it in makes a sealed joint to prevent'egress of the contained fluid. 1 When raised slightly, the fluid again flows in from the jar and fills this recess and the cup or chamber. -As shown in Fig.1, this cylindrical forcing chamber or cup F is covered over above with theperforated cover pierced with exit-holes ff to permit the fluid above the plunger tofiow out when the said plunger has been raised. The plunger D fits this forcing-cylinder'likea piston and at its middle has a hole which discharge-pipe D, rigidly secured thereto, so

down and the plunger then descends the con tained fluid will be forced upward through margin of the jar A to its discharge-exit D, where it may be caught in a tumbler placed glnderneath and adjacent to the face of said ar. 1 v v To insure the consecutive movements of the plungerv and forcing-chamber, I provide the handle Eat the top of the stem E", which passes down vertically to the plunger D to ,which it is attached. A coiled spring E, Figs. "11, 6, and7, maintains this handle in an elevated position, so as to hold up" the bottom margins of the forcing-chamber F from contact with't'he recess A. A coiled spring D beneath the cover 0 bears beneath upon the collar F of the forcing cup or chamber F and above "against a collar d upon the plungerretracted to the upper part of the chamber F except when forced down against the tension of this spring D by pressure'npon the handle top of the-forcing-chamber F and at their upper ends passing through perforations in the ment of the plunger D to carry down the joint between the plunger D and the neck F of the forcing-chamber F, as shown in Fig. 5. These rods are lettered D D and are .provided with collars d (1 Figs. '4 and 5, which may be made vertically adjustable, if desired. These collars d ,,striking against the under side of the cover 0, arrest the upward motion of the forcing-chamberat a proper height, while the spring E continues the ascent of the plunger D in the chamber F.

else in contact with its sloping sides andv that when. the forcing-chamber is pressed opens into and forms the inlet of a vertical thepipe D' and thence outwardly over the IIO stem D E, sothat the plunger D is constantly -E. In Figs. 4 and 5 instead ofthe spring D' ,I use one or two rods attached below to the cover 0, and to enable thedownward move- 1 forcing-chamber F, I make a sliding friction- 1 In Fig. 5 instead or using the coiled spring E, I operate the tube D by means of a pivoted lever E pivoted to D at e and to the cover at C, and use the hinge-spring E to hold the lever-handle E elevated against pressure.

The inside of the collar F, as shown at Fig. 2, I prefer to make, when thick syrups are used, with vertical flanges around the tube D to prevent sticking from crystallization of the syrup. The lever-handle E E (shown in Fig. 5) may be used with the devices shown in all the other figures, if desired.

In Fig. 6 instead of a rigid forcing-chamber F, I use a collapsible elastic rubber cup F, open beneath, perforated at its center for the discharge-pipe D, and secured to the; lower end of the same. Above it is the flat plunger or rigid portion F, the purpose of which is to compress the top of the pressure-chamber and so eject the fluid through the tube D and the discharge-nozzle D.

In Fig. 7 I use a mechanism similar to that shown in Fig. 1, except that the plunger-stem E is solid, the plunger D is without a perforation, and the dischargc -pipe' D is carried up directly from the bottom of the recess A,

so that it does not rise and fall with the movements of the plunger, but is fixed with reference to the jar A. The springs E and D" have the same functions as in Fig. 1.

In Figs. 1, 1", and 1 I show the means which I prefer to use to prevent drip from the discharge-nozzle D or the entrance of insects or dirt thereto. In Fig. 1 is shown a cylindrical plug E, which occupies the bore of the tube D and reciprocates therein across thedischarge-opening D It is connected with an arm E, which is pivoted at C by means of the pivot e to the top of the fixed cover, so that as the handle E is depressed, carrying with'it vertically the tube D, the arm E will thrust forward the sliding plug E within the tube D and uncover the vent D When the handle E again rises, it will draw back the plug E over the vent D and again close the same. In Fig. 1" the same devices areshown, excepting that instead of an internal plug E an external sleeve E is used, which opens and closes the exit-opening D in the same manner.

In Fig. 1 an internal plug E is employed, as in Fig. 1"; but this is connected to astem E, supported by acoiled spring a, and the inward force of the fluid compresses this spring and opens the vent, which again closes when pressure has been removed from the handle E. The form shown in Fig. 1 is especially adapted for use with the modification shown in Fig. 7.

In Fig. 1 I have indicated the use of the form shown in Fig. 1.

While I show these various devices hereinabove described as in use together in my improved discharging mechanism for syrupjars and the like, I do not always use all these devices together, and I also vary the same to conform to special applications and requirements as would be done to meet such conditions by any skilled mechanic and without departing from the principles ofv my invention as herein shown, described, and claimed.
