Like numerals refer to like parts throughout the several figures.

.f I have shown in the drawings one form of delvice embodying the invention. In this construcmembers Il and l are provided with bent edges I0 and l I` which project into grooves 'in the member 9. The parts are held together by the fastening devices I2 which engage the inner member 'I and which passes through the insulating material 8 an'd the outer member 6 and are connected with the handle I3, which bears against the outer member 6, so that the handle and fastening parts therefore act also to hold the several parts of the cover together.

'Ihe inner metal members and the outer metalv members of the casing and the cover are so arranged -as` to prevent heat transfer between them so as to prevent the outer metal members from becoming cold and sweating and from conducting outside heat into the casing so as to reduce the efficiency of the device. For this purpose the upper open end'of the casing is provided with a separate insulating member ,I4 which extends therearound. 'Ihis insulating member I4 is preferably of rubber, although it may be of any suitable material. The metal member 2 is provide'd with a ange I5 and the separate insulating member I4 is fastened to this flange by the fastening devices I6. There is a metal member I'I between the head of the fastening member I6 and the insulating member I4. The inner metal member 3 is provided with a hook flange I8 which is hooked into a recess in the separate insulating member I4. It will be seen that by this construction therev is no heat transfer contact between the inner metal member 3 andthe outer metal member 2. The insulating member I4 has a projecting part I9 which projects beyond the outer metal member 2.

The insulating member 9 on the cover is provided with a groove 29 into which the projection I9 is received. The insulating material 9 has a projection 2I which engages the outer metal member 2. By the construction herein shown there is no heat transfer connection between either the metal members 6 and 'I of the cover and either of the

metal members

2 and 3 of the casing, so that the metal member 6 of the cover does not get cold and sweat and does not act to transfer outside heat into the interior of the casing.

Within the casing is a sirup container 22 which contains the sirup which is to be mixed with the charged water to form the beverage. container 22 is supported in any desired manner. As herein shown it is provided with a discharge member 23 which projects into the hollow of the angle sirup conducting member 24. The sirup container is supported by this Vangle member 24. The discharge member 23 is preferably separated from the sirup container, but fastened thereto, and there is preferably an intervening washer 25 of non-conducting heat material between the angle member 24 and the sirup container. The

sirup container is fastened to the member 24 in any desired manner. As herein shown there is mounted in the member 24 a holding member 26 which preferably has a. threaded connection with the member 24. A strainer 21 is associated with The sirup sirup measuring and mixing device which measures the sirup and mixes the sirup with the charged water. Fastening devices 36a on the sirup container engage holding devices 30h attached to the casing. o Y

As herein shown, the sirup measuring and mix 'ing device comprises a main body 3| in which is mounted a hollow cylindrical sirup-controlling member 32 which is rockably mounted in the main body of the measuring and mixing device. The member 24 is preferably permanently connected with the main body 3| in any suitable manner as, for example, by welding and discharges sirup into the controlling device 32'. The sirup controlling device 32 is provided with a discharge opening 33. The main body 3| is provided with a sirup measuring chamber 34 which has an inlet 35. Some means is provided for rocking the controlling member 32 so as to move the discharge opening 33 into position to register with the admission opening 35, whereupon the measuring chamber 34 is lled with sirup and thereby measures .the quantity of sirup to be used for eachV drink. A spring 35a removably connected to part 35h and member 26 elastically presses conical shape member 32 against its seat.

As herein shown, the controlling member 32 is rocked by means of a handle 36 on the outside of the casing. This handle is connected with the controlling member so that it will rock it but is arranged so that it may be entirely disconnected therefromso that the sirup measuring and mixing device and associated parts can be easily and quickly removed from the casing.

In the construction shown, the controlling member 32 is provided with a connecting member 31 which is attached thereto by a pin 38. This connecting member is provided with a slot 39. A connecting member 40 is attached to the handle 36 and has a portion 4| which enters this slot, see Fig. 3. When the handle is turned the controlling member 32 is turned so as to turn the connecting member to connect or disconnect the

opening

33 and 35. A connecting member 46 is connected with the handle 36 in any desired manner. As herein shown, this connecting member has a knurled end 42 which is driven into the handle 36. The connecting member 40 passes through a sleeve 43 on the interior of the bushing 44. The connecting member 40 is provided with a groove 45 and there is a pin 46 lwhich projects into this groove and which is held therein normally by the spring 41. 'This permits the connecting member 40 on the handle 36 to be rocked, to rock the controlling member 32 to connect and disconnect

openings

33 and 35 and to connect the passageway 40a to the air inlet passageway 40h and pipe 40o at one end and with the sirup measuring chamber 34 at the other end.

To disconnectthe connecting member 40 from' the connecting member 31, the handle is pulled outwardly so that pin 46 moves out of the slot 45. The

members

40 and 31 are again connected by pushing the connecting member inwardly until pin 46 enters slot 45.

The bushing 44 is provided with a slot 4.8, see

4a downwardly projecting pipe 1|.

Fig. 5, and the handle 36 is provided with a pro- .iection 48 which works in the slot and which limits the rocking movement of the handle and the controlling member 32. 'I'he bushing 44 has an enlargement 50 which engages the outer wall of the casing so as to limit the inward movement of the bushing.

There is preferably a packing member 5|, held in position by a packing nut 52. The main body 3| of the sirup measuring and mixing device is mounted upon a holding frame 53, see Figs. 8 and 9, which has an opening 53a through which bushing 44 and connecting member 40 pass., A pin 53b passes through frame 53 into bushing 44 and a nut 53e prevents withdrawal of the bushing 44 (Fig. 3). The body/3| is held in position on said frame by the removable pin 54 which has a conical shape end 55 entering a conical shape opening 56 on one side Aof the frame 53. The pin 54 is provided with a conical shape head 51 which enters a conical shape opening 58 at the other side of the frame 53 and engages the main frame 3|. The opening 58 is shown as being made in a projecting part 59. The head 51 is heldin place and pressed against the frame 3| by means of a nut 60 which has a threaded engagement with the projection 59 and which has engaging part 6| which engages the head 51, see Fig. 8.

The frame 453 for the sirup measuring and mixing device is provided with a hollow threaded projection 62 which engages a hollow clamp nut 63, see Fig. 3. There is a spacing collar 64 between the clamp nut and the insulation of the casing.

Y The carbonated water preferably passes through a pipe coil 65, which has a. threaded end piece 66. which is-threaded into a projection 61 on the side 68 of the sirup measuring chamber 31. The coil 65 has at the other end a threaded connection 68a for connecting it with the source of the charged water. 'I'he charged water passes through a suitable screening or filtering device 69 and enters a pipe 10, passing through the sirup measuring chamber 34 and connecting with The pipe 1| is supported on the' main frame 3| by having a screw threaded connection therewith (Fig. 6). The end of the pipe 1| is normally closed by a valve ,12 attached to a piston 13 sliding in a cylindex' 14. The piston 13 has a groove 13a to retain liquid which'may attempt to get past the piston and when the piston is moved down, this liquid is discharged through the opening 13b. The cylinder 14 has removably attached thereto a hollow end piece 15. 1

Springs

16 and 11 engage the end piece 15 at the lower end and are arranged to exert an upward pressure on the piston-13 so as to maintain the valve 12 closed against the end of the pipe 1|.- A valve 18 normally closes the dis'- charge passageway 19 of the sirup measuring chamber 34. cylindrical member 86 which extends down along the cylinder 14 to a point near the end of the end piece 15.

A series of supporting members 8| connect with 1 the piston 13 and engage the valve 18, the

springs

16 and 11 exerting sulcient pressure upon the piston 13 to cause the supporting member 8| to hold the valve 18 in its closed position. A pin 62 -slides into an opening in the frame 3| and pre- This valve is connected with a net joints. In the construction shown, the frame 3| is provided with one or more bayonet.- lock pins 88. The nozzle member 83 is provided with the bayonet slots 85 (Fig. 3). The outer nozzle member 83 is placed in position by moving it up until the bayonet lock pins enter the upper part of the slot then rotating it to the position shown in Fig. 3.

The sirup discharge valve 18 and the carbonated wat'er discharge valve 12 are actuated by the movementof the handle 36. The rotation or rocking of the handle 36 moves the controlling member 86, associated with the said handle (Fig. 7). There is a limiting device 86a which works in a groove' 86h in the member 86 and which limits the outward movement of the controlling member 32. This limiting member is held in position in any desired manner, as by the screw 86c. In proximity to the controlling member 86 are the actuating

members

81 and 88 connected together by the connecting member 89.' There is preferably an engaging part 90 on this connecting member which is preferably a roller (see Fig. 7). The lcontrolling member is provided with a projection 9| which, when the controlling member is moved, engages the member 90 and moves the

actuating members

61 and 88 downwardly. These actuating members engage the discharge valve 18 for the sirup measuring chamber 34 and, when moved, moves this valve to its open position. The

actuating members

81 and 88 have associated therewith the springs 81a and 88a which when the roller 30 is released, return the

actuating members

81 and 88 to their original position. In the construction shown. the member 86 forms the end of the controlling member 32 (see Figs. 3 and 6).

The valve 18 rests upon aplurality of pins 8|. These pins connect with the piston 13 so that when they are moved down, the charged water valve 12 is moved down away from the end of the pipe 1|, so as to open this pipe and the charged water then passes up and out through openings 93 in the side of the cylinder 14 and openings 94 in the top 95 of the cylinder 14. This cylinder is connected with and supported upon pipe 1| by means of a screw threaded connection between the top 95 and thevpipe (Fig. 6).

' The sirup chamber discharge valve 18 is held in position by the pins 8| vand the piston 13, the

springs

16 and 11, and the

parts

14 and 15. When the handle 36 is moved, the sirup valve 16 and the charged water valve 12 are opened. During this time the sirup measuring chamber 34 is connected to the outside atmosphere by the pipe 40e and passageway 30a, extending through the controlling member 32 so that the sirup is free to move outfof the sirup measuring chamber. The sirup passes out through passageway 19 and in through the space 96 between the nozzle members `8l! and 83. The charged water surges up through the

openings

93 and 94 and passes along the space 31 between the nozzle members 1l and 80.

The sirup and the charged water then meet in the nozzle and are discharged "nto the receptacle so as to produce the mixed drink of the sirup and the charged water. There is an adjusting member 98 which is adjustably connected with the frame member 3| and by means of which the size of the Sirup discharge opening 19 may be adjusted to meet the conditions presented.

When ice is used to cool the sirup and the charged Water, the receptacle is provided with an overflow pipe through which the Water produced by the melted ice escapes. This overilow `

nozzle members

83 and 83.

pipe is preferably provided with a guard mem`y in the construction herein shown as'follows:.

The pipe 10 for the charged water, which 1s controlled by the valve 12, is provided at its lower end with a nozzle construction 1|a which reduces the size of the passageway and increases the pressure at the point where the charged water is released, and the velocity of the charged water. This charged water is under a comparatively high pressure and the sirup drops only by gravity, so that when the valve 12 is opened, some of the charged water gets into the glass ilrst and then the sirup follows, and this produces a much better drink. The two valves for the sirup and the charged water are opened at substantially the same time but since they are under different pressure, the sirup owlng by gravity and the charged water by'a high pressure, the charged water reaches the glass i'lrst and the sirup follows and the two then enter the glass together.

The use 'and operation of my invention are as follows.

When the device is put into use the parts are assembled as herein shown. Sirup is placed in the sirup tank 22 and the sirupmeasuring chamber 32 is connected with the source of carbonated water and the cooling material is placed on the inside of the casing. When it is vdesired to dispense a drink, the lever 36 is moved into the position shown in dotted line in Fig. 1. This movement of the handle causes the controlling device 36 to move so that the projection 9| engages the rollerv and moves the actuating members 81` and B8 so as to move the sirup measuring chamber'valve 13 to its open position to permit the escape of the sirup. This sirup then passes down along the space 36 between the At the same time the downward movement of the valve 18 through the agency of the pins 8| causes Vthe piston 13 and the charged water valve 12 to be moved downwardly so as to open the valve 12 and permit the escape of the charged water, /which surges up through the

openings

93 and 94 and passes down through the space 31 between the

nozzle members

16 and 63.

The charged water and the sirup then meet vand pass out of the nozzle into the receptacle so as to form the 'charged drink.

The movement'of the handle 36 also partially rotates the controlling member 32 so as to disconnect .the openings 33 land 35 and shut off the further flow of sirup into the sirup measuring chamber 34. This movement of the controlling member32 moves the Darts so that the passageway 40a of the controlling member 32 has one end connected with the pipe`40c and the other end with the Sirup measuring chamber 36 so that air may pass into the sirup chamber 3l to permit the proper discharge of the sirup therein through the open valve 18. The handle may be moved back to its original position, whereupon the

valves

12 and 18 and associated actuating parts will be moved back to their initial position by the

springs

16 and 11, and 31a and 88a.

The sirup tank and sirup measuring and mixing device and the nozzle may be easily and quickly removed from the receptacle by taking off the cover` 5, disconnecting the carbonated water pipe 65 from the sirup measuring chamber and removing the holding or fastening device 54, whereupon the parts may be lifted out of the casing for examination, cleaning, repairing and so that the sirup container and sirup measuring and mixing device may be removed through the open top of the casing.
