Frick, Muncie, Ind., assignor to Glascock Brothers Mfg. 00., Muncie, Ind., a corporation of Indiana Application February 1'1, 1932. Serial No. 593,514 8 Claims. (Cl. 62-1) My invention relates to bottled beverage disforming a receptacle.

This latch member is pivotally 85 fore it is dispensed. moiuited on a rod 19 extending between the side For the purpose of disclosing my invention 1'. walls of the casing of the lock and is normally have illustrated one embodiment thereof in the biased towards latching position by means of a accompanying drawings in which Fig. 1 is a side coil spring wrapped around the rod 19 and having elevation of a beverage-cooling refrigerator emone end 20 bearing on the latch member 18 and 90 bodying my invention; Fig. 2 is a transverse secthe other end 21 bearing on a pivoted projecting tional view; Fig. 3 is a side elevation, the cover member 22.

When the member 22 is in its projected position 105 In the embodiment of the invention illustrated (see Fig. 3) the latch member 18 projects above the refrigerator may be of any type but is illusthe edge of the cover 15, thereby preventing the trated as comprising an outer casing 1 which may opening of the cover, although under abnormal be formed of sheet metal, and an inner casing or circumstances, if the operator desires, he may tub 2, preferably formed of sheet metal and press on the latch member 18toretract the same against the action of the coil spring to retract the latch member and permit the opening of the cover member. Furthermore, by this arrangement. with the lock in looking position, and the cover member raised, when the cover is dropped it becomes automatically latched.

For releasing the latch I provide an electromagnet or solenoid, whichever may be desirable, 28 which, when energized, will raise the stop arm 24 out of engagement with the stop bar 25, permitting the projecting member 22 to be retracted under the influence of the coil spring 23 and thereby retracting the latch member 18 to permit the opening of the cover 15. For projecting the projecting member 22, when it is desired to prevent the opening of the cover I provide a solenoid 27, the core 28 of which, when projected by the energization of the winding of the solenoid will engage a plate 29 on the projecting member 22 and move the projecting member into its projected position and at the same time in a position to permit the stop member 24 to drop in front of the plate 25, holding the projecting member 22 in its projected position.

It will be understood that a separate lock is provided for each of the compartments 4, 5 and 6. For controlling the lock I provide a thermostat 30 conveniently arranged in the compartment and subject to the temperature thereof. This thermostat has a cold contact 31 and a hot contact 32. The thermostatic member 33, which may also be a contact member, is connected by a conductor 34 with one side 35 of the current supply line. The cold contact 31 is connected by a conductor 36 with a stationary contact 37. A second stationary contact 38 is connected by conductor 39 with one terminal of the electromagnet 26. The opposite terminal of this winding is connected by conductor 40 with the opposite side 41 of the supply line. For bridging the contacts 37 and 38, under certain predetermined conditions, I provide a conductor plate 42 mounted on the projecting member 22.

The hot contact 32 of the thermostat is conected by a conductor 43 with a contact 44 and contact 45 is connected by a conductor latch 18 so that the cover 15 may be opened. As soon as the projecting member 22 is moved to its retracted position the bridging member 42 moves of! of contacts 3'7 and 38, opening the circuit of the electromagnet 26 so that this solenoid will not continue to heat up through continual sage oi current therethrough.

Assume that sufficient cooled bottles have been removed from the compai tment and warm bottles substituted therefor. until the temperature of the compartment has been raised above the predetermined cooling temperature. Under these circumstances the thermostatic member 33 will move into contact with the hot contact 32, thereby establishing circuit through the contacts 44 and 45, across the bridging plate 48, it being remembered that this bridge plate has been moved to bridging position, and through the solenoid 27. This solenoid being energized, will project its core 28 to move the projecting member 22 into its projected position, thereby throwing the latch 18 into latching position. The final position of the projecting member 22 is such that the bridging member 48 will have moved oil the contacts 44 and 45 before the stop member 24 drops in position, thus opening the circuit of the solenoid 27. There is sufficient inertia in the solenoid core 28 in its projecting movement to cause this action. The latch is now in latching position and will remain so until the temperature has again dropped to the satisfactory point.

As an additional precaution against removing bottlesfrom a compartment which has not been sufliciently chilled, I provide an extension 49 having the words Cold and "Warm" thereon and in such a position that when the latch is in a position to permit the removal of bottles from the compartment the word "Cold" will be displayed through an opening 50 in the casing of the latch and when the latch is closed the word "Warm" will be displayed.

It is thus seen that by the provision of a plurality of compartments certain of these compartments may be cooling the beverages while service is made from one compartment, those compartments which are not ready for use being latched against mistaken dispensing therefrom. As soon, however, as the compartment is ready for dispensing purposes the latch will be unlocked. permitting dispensing therefrom and the warmer compartment will be closed pending the proper chilling of the bottles therein.

By this arrangement a smaller refrigerating tmaybeusedasitmaybeoperatingtocool the bottles in certain of the compartments pending the opening thereof for dispensing and there will not be the necessity for imposing an extremelyheavy load on the refrigerating apparatus for the purpose of chilling one compartment from which bottles are being constantly removed.

In order to assist in the cooling of the bottles the compartments may be suitably filled with a cooling liquid such as water or the like.

In the structure illustrated in Figs. 9 and 10, I dispense with the electromagnet operating means and control the lock directly from the thermostat. In this structure the projecting member 22 and the latch member 18 are of the same construction as illustrated in connection with 5 Figs. 1 to 8.

Within the compartment, the opening of which is to be controlled, I preferably arrange a thermostatic tube 51 which may be tilled with any suitable fluid or gas expansible and contractible 1 0 under the influence of heat or cold. This tube is connected by a tubular conduit 52 with an expansible member 53 of any of the well known commercial types, one of which is sold under the trade name of Sylphon. This expansible member is somewhat of the bellows type and has secured to the top thereof a pin 54 adapted to be raised by the expansion of the sylphon. An operating arm 55 is pivoted at 56 on a suitable base member 57 and has one end thereof connected by an adjustable connection 58 with the projecting member 22. On the opposite side of the pivot point 56, the pin 54 bears in opposition to a coiled spring 59, provided at its lower end with a head 60 having a pin member 61 engaging the arm 55 on the side opposite the pin 54. The upper end of this spring bears 'on an adjustable stop 62 mounted on a threaded stem 63, in turn supported on the base member 57.

The operation of the device is obvious. When the temperature in the compartment to be cooled is lowered to the desired predetermined point the bellows or expansible member 53 will contract permitting the spring 59 to operate the arm 55 to retract the projecting member 22. This withdraws the ilatch member 18 from latching position so that the compartment may be opened. As when the temperature in the compartment rises above thepredetermined desired point, the expansion of the' fluid or gas in the thermostatic member 51, the tube 52 and' the bellows 53 operating the arm 55 to project the member 22 so that the latch member will again be projected in latching position.
