Be vit'known that I, CHARLES N. CHAD BOURN, of Minneapolis, in the county of Hennepin, State of Minnesota, have invented certain Improvements in Pneumatic Syrup-.I ars for Soda-Fountains, of which the following is a speciiication.-
This inventionrelates to im provementsin syrup-jars for soda-fountains; and the objects I have in View are to provide a syrup-jar from which thesyrup may be forced by pneumatic pressure; also, to provide a series of such jars in connection with a single pump so arranged that the syrup maybe forced from any one of the jars at will also, to provide a jar that-can 4 b'e readily remoyed and refilled withnutremoving any'of the other jars; also, to provide a jarwith au outlet pipe ortubev in which any of the syrup remaining in the tube may be drawn back into the jar instead of being allowed to drip from the open end of the tube.
Other 'objects of the' inventionwill appearl from the fouowing detailed description, raken in connection with -the accompanyingdrawings, in which- 'i Figure 1 is a rear view of a number' of syrupjars embodying my invention, showing the arrangement of the jars in the soda-fountain. Fig. 2 is avertical section of a portion of a soda-fountain and one of the jars and its connections.
In 'the drawings, 2 represents a syrup-jar that may be of any ordinary or preferred con- I prefer to employ a common Mason glass jar having a -screwthreaded top,
. which is' adapted to be screwed into a screwthreaded cover 3. The cover 3 is provided with a suitable filling-orifice having a cap 4. The, cover 3 is also provided with an outlettube 5 andan air-inlet tube 6. The jar, with its connections, is' preferably located behind a narrow plate or slab 7, preferably of marble, and a series of -these slabs arrangedside by side, as shown -in Fig. 1, make up a section of i the*4 front of the soda fountain. These plates preferably rest on a marble or other slab' (see IFig.,2) and t against 'a stop 7".
Each' of said plates or slabs is preferably providedv with ya hook 8 atits lower end, which l Fig. 3 is a representation of a' pump that may be employed in Aconnection liivithfthe jar.l
hooks over a rod 9. (See Fig. 2.)r The weight of the jar holds the plate in position. When is desired to remove auyjar and plate, the 'handle 13 is grasped and the topof the plate is tipped outward until it clears the slab "or plate above, and then the plate is lifted to free the hook 8 from the rod 9'.' The jar-cover 3 is secured to the back ofthe plate or'slab 7 by a suitable bracket 8. The cover being held by the bracket and the jar being screwed into the cover, the jar is held suspended thereby, as shown in Fig. 2.- The tube 6 is 'connected to a cock 9, the plug l0 of4 which is provided with a hole or opening 11, and a stem i12 is connected to the plug 10 and Vpasses aliroagh the plateer stab 7 'and is provided with a handle 13, by means of which the plug may be turned. A pipe 14 is arranged above `the series of jars, as shown in Fig. 1, and each cock 9 is connected to thepipe 14 'bya rubber or other fie'xible tube land coupling 1'5, which permits any one of the jars to be'drawn forward a su cien't distance to enable it tobe filled or detachedat the coupling. A suitable air-pump is connected to the pipe 14 by any suitable means, as the tube 16, Fig. `1. In' Fig. 3 I have represented an air-pump provided with a barrel 17 and plunger-rod 18, having a cap or head 19 and surrounded by a spring 20. The'tube 16. is 'connected to the barrel of the air-pump. j
The cocks 9 are normallyclosed, so as to prevent air being forced into the jars. 'When it is desired to draw syrup from any jar, the `cock for that jar is opened, the pump is operated by. foot or other pressure, and air is forced into that jar and the syrup is forced out of the pipe 5.: In practice a partialstroke of the piston of the pump will force fromthe jar as much syrup as it will :be 'necessary to draw at one time, and the return'stroke of .the pump-piston will suck back into the jar any syrup there may bein th tube'. I
may also provide a lip or ledge 2 nearthe" end'of the tube,` so vchat any syrup' in #the tube when the` air-pressure ceases will' be compelled to run back into the jar, the tube -5 being preferably arranged onfaninclie. For the purpose of insuring the immediate stoppage of'the llow of the 4sj'frup when the Ioo pump is stopped and -the drawing back'intoj .ment of the'pistonceases and the pressure ,is removed from the piston-rod the spring begins to move lthe piston in the opposite direction and the movement of the piston' draws the air back into the jar through the tube 5, andl thereby sucks back into the jar any syrup there may be in this tube.
` I do not confine myself to any particular construction vor arrangement of the air-pump, but prefer to use a pump that may be operated by foot-power, as I consider this the most convenient. A hand-pump may, however, be used, if preferred.
The tube 5 is preferably provided with a movable .extension 23,.arranged to telescope over the lower end of .the tube for the purpose of adapting the tube for use with jars i of different heights.
Instead .of using a pump I may use any other suitable means for" creating a pressure of air'in thejar. Instead of using the screwthreaded connection between the cover and jar I may use yany'other clamp that will insure an air-tight closure of the jar.
I do not confine myself to the details of the construction shown and described, as the samemay be varied in many particulars without departing from my invention.
