AIPPARATUS FOR AERATING LIQUIDS.

Application filed. December 21, 1925, Serial No. 76,880, and in Great Britain December 20, 1924.

This invention relates to apparatus for aerating liquids and is more particularly intended for use in making soda water, the apparatus being of the kind that is supported in its working position by the delivery pipe of the aerating gas container or cylinderto which it is adapted to be attached and in which a bottle guard or shield is provided to cover the bottle containing the liquid to be aerated so as to prevent injury to the operator in the event of the bottle bursting during the aerating operation.

According to this invention the apparatus is provided with means whereby the movement which efiiects the engagement of the bottle containing the liquid to be aerated with the aerating gas inlet orifice of the apparatus also causes the bottle guard or'shield to assume the protecting or closed position around the bottle the movement of the bottle guard or shield into this position being timed to take place preferably before the bottle is fully engaged with the said aerating gas inlet orifice and the disengagement of the bottle therefrom being timed to take place guard or shield 1, but shewing the bottle guard or shield: in the protecting or closed position.

Figure l is a plan view shewing the bottle guard or shield in the open position in full lines, in the partially closed position in dot and dash lines and in the fully closed position in dotted lines.

Figures 5, 6 and 7 are similar views to Figures 1, 2 and 3 of a modification.

Figure 8 is a plan view showing the bottle guard or shield in the open position in full lines and in the protecting or closed position in dot and dash lines, and

Fig. 9 is an enlarged sectional view taken a on line 99 of Fig. 4: showing the hinged connection between the stationary part and the movable part of the bottle guard.

Like letters of reference are used throughout the drawings to denote similar parts.

The apparatus comprises a frame consisting of two upright portions A, A and a horizontal portion A the frame being conveniently made by bending a bar or strip of metal to .the shape shewn. The frame is attached at its upper end to a cross piece B by means of screws C, C, C, C, this mode of attachment enabling frames of varying lengths to he used to suit different sizes of bottles. The horizontal portion A of the frame carries a platform or support D on which the bottle containing the liquid to be aerated stands. In Figures 1 to 4 the said platform is adjustably mounted in the portion A by means of the screw threaded stem cl so that by rotating the handle at thereon the platform can be raised or lowered in the frame. The bottle guard or shield consists of a stationary part E and a movable part E both of semi-circular shape. In Figures 1 to 4 theiixed part E is attached to a disc F having a screw-threaded portion F which engages with a correspondingly screw-threaded portion in the cross piece B through which it extends and the movable part E is hinged vertically to the fixed part E. 'The said disc F and the screw-threaded portion F have a passage 7? through them which passage communicates with a lateral pipe G provided with a joint by which it can be connected to the outlet pipe of the aerating gas container or cylinder, said pipe serving to support the apparatus in its working position on the aerating gas container orv cylinder and to conduct the aerating gas therefrom. The passage terminates at its inner end in a conically shaped nozzle H which constitutes the aerating gas inlet orifice of the apparatus and against which the bottlejcontaining the liquid to be aerated is engaged during the aerating operation. The frame is provided with a handle J by which it can be turned on the aforesaid screwthreaded portion F. In use the frame is turned or angularly displaced by means of the said handle on the screw-threaded porliquid to be aerated is then stood on the platform D. The frame is then turned inthe opposite direction which causes it to rise on the screw-tl'ireaded portion F and the bottle to approach the nozzle H. During this turning movement a projection or arm L on the upright A comesinto contact with the movable part E of the bottle guard or shield and turns it into the protecting or closed position (seeFigure 4). The distance through which the frame moves upwards compared with the angular. movement thereofis such, that engagementrbetweeni the bottle and the nozzle H cannot take place ,until the movab-lepart E of the bottle. guard. or shield has assumed its nearly ,closed position, the actual. engagement between the bottleand the nozzle H occurring during the last part ofthe. angular movement of the vframe during which. the rear end. of the projection or arm; L comesagainst the mov- ,able part E of thebottle guard or shield andretains it in its protecting or closedlposition while the frame is completing its. up

ward movementto bring the bottle into contact with the nozzle H whereupon the aerating gasisadmitted: to the .bottle invthe usual manner. After the aerating. operation has beenucomspleted the. frame is turnedvin the :opposite direction so as to lower the bottle from the nozzle I-Lihut thebottle guard or v shield isstill :kept in, its protecting or :closed vposition by the rear end cof the projection .or arm L, untiltthe frame has been turned sufficiently, to move it the upright A out ofthepath of the movablepart Ei" ofthe bottle guardzor shield, whereupon the latter .is able to assumeits' open position under theinfiuence of the aforesaid springs. M. and

the bottle thencanbe removed from the apparatus. The rear end of" the projection or 7 arm Luis provided. with a roller [to reduce friction when contacting with the movable part E1 of the bottle guardlor'shield.

Instead ofim-parting upward and downward movement to the. frame to effect the engagement and disengagement of the. bottle with the nozzle H, the bottle-platform D may be moved upward and: downward. in the frame; An example of this is given in Figportion vor neck 6Z having acam-shaped sur-' I ures 5- to 8 wherein the bottle platform- D is looselymounted in the lowerpart of the frame and has a downwardly projecting face cl wliich cooperates with acorresponding cam-shaped surface cl? on a fixed mem her (1 carried by the horizontal part A of theframe. The neck 03 is providedwith a handle J by which it can: beYrotated,-thereby raising or lowering the bottle platform D on the fixed member d to bring the bottle into or out of engagement with the: nozzle H. The bottle platform has a spindle cl which passes through the fixed member is surrounded by a spring d hsituated between the lower surface of the horizontal part A ofthe frame and a nut on the end of said spindle, the object of the spindle beingto guide the bottle platform-during its movements and of the spring to assist-the bottle platform to return to its lowest position. In this casethe bottle guard: or shield is moved into its protecting or closed position'by apin L attached to the hand-1e J and exten'd'ingvertically upwards therefrom, said pin coming into contact withv the movable part E" of the bottle guard of the sl'iield when the handled is operated as shewn in the two positions of the parts in Figure 8. Instead of moving the bottle platform upwards and downwardsby a cam device a screw-thread device might be used to give the necessary movements;

In Figures 5 to 8 the frame of the apparatus is shewn with an extension: piece i shaped at its outer endto fit roundthe- Wall of the aerating gas container or cylinder, the object of which is to hold the apparatus steady during use.
