- the door is moved downwardly into the wash water tank whenmoving it into open position to give access to the wash and rinse compartment. This will leave the top of the counter clear at all times.
- the weight of the door is counterbalanced by a weight and so the door will remain in the position into which it has been moved whether opened or closed.
- a modified form of the device will permit the door to open by gravity after the washing and rinsing cycles.
- An object of our invention is to provide a drinking-glass or dishwashingmachine in which the door that normally closes the wash andrinse compartment is moved downwardly into the wash water tank during the manual opening movement of the door. This will keep the counter clear while permitting drinking glasses or dishes to be placed in the wash and rinse compartment or be removed therefrom by the bartender.
- the door can be counterbalanced so as to remain in either opened or closed position.
- a modified form of the device makes use of an automatic lock that will hold the door closed during the wash and rinse cycles of the machine and then will release the door to permit it to open by gravity.
- FIG. I is an isometric view of the drinking-glass or dishwasher and shows the wash and rinse compartment door in open position.
- FIG. 2 isan isometric view of the door.
- FIG. 3 is a front elevation of the wash and rinse compartment with the door removed in order to illustrate the counterweight mechanism for supporting the door. The hood and its supporting back are illustrated.
- FIG. 4 is an enlarged horizontal section taken along the line 4-4 of FIG. I and shows the guides and rollers for permitting vertical movement of the door from closed to open position and vice versa.
- FIG. S' is an isometric view of a modified form of drinkingglass washer and illustrates the door for the wash and rinse compartment in open position.
- FIG. 6 is an isometric view of the door used in the modified form, the door being of the same type as that shown in FIG. 2 except that it is provided with a lock-lever-receiving keeper.
- FIG. 7 illustrates the counterweight mechanism for the modified form ofdoor and this is the same as that shown in FIG. 3 except the counterweight is lighter in weight than the weight of the door.
- FIG. 8 is an enlarged horizontal section taken along the line 8-8 of FIG. -5 and illustrates the guide mechanism for the door.
- FIG. 9 shows the circled dot-double-dash portion 9 of FIG. Sand illustrates the lock-lever engaging with the door keeper for holding the door in closed position during the washing and rinsing cycles.
- the device comprises a tank indicated generally at A and which is adapted to hold wash water that is normally kept at a temperature of about 140 F.
- the tank is provided with the usual hot water inlet, not shown, and pump, not shown.
- a power wash temperature gage is shown at l and a final rinse gage is shown at 2 in FIG. 1.
- Control buttons for the drinking-glass washer are shown at 3 and 4.
- the tank A has a combined hood support and door guide B that extends upwardly from the rear wall of the tank, see FIGS. 1,3 and 4.
- a hood C is supported at the upper end of the support B and it extends over the top of the tank A and is spaced thereabove so as to provide an area for receiving a basket of drinking glasses, not shown.
- FIG. 2 shows the three panels 6, 8 and 9 of the three-sided door D reinforced by an inwardly extending angle iron 12.
- the door handle 5 extends transversely across the front panel 6 of the door and has its ends supported by brackets 13-13 that in turn are secured to the side panels 8 and 9 of the door.
- the three-sided door Dis guided in its vertical movement by guide rollers on the door riding on inwardly extending and vertically disposed guide flanges 14-14 that are integral with the hood-supporting back B, see FIGS. l, 3 and 4.
- Upper brackets 15-15 are secured to the door side panels 8 and 9, and rotatably support upper guide rollers 16-16 that ride along the inner surfaces of the flanges 14-14, see the enlarged sectional view of FIG. 4.
- Each side panel 8 and 9 of the door also supports a pair of middle brackets 17 and a pair of lower brackets 18 that in turn rotatably carry door guide rollers 19 and 20, respectively.
- These pairs of rollers 19 and 20 ride on the outer surfaces of the flanges l4 and are disposed below the rollers 16-16.
- This arrangement of guide rollers holds the door D in a vertical position during the closing and opening movements of the door.
- a bracing and supporting bar 21 extends transversely across the open back of the three-sided door, and the ends of the bar are bent at right angles and are secured to the inner surfaces of the door side panels 8 and 9. Cables 22-22 have one of their ends connected to the bar 21 and then are passed around pulleys 23-23, see FIG. 3, that are rotatably carried by the inner surface of the hood support B, and they have their other ends connected to a counterweight 24. The weight 24 will hold the door D in any position into which it has been manually moved by the operator by means of the handle 5.
- FIG. I shows the wash water tank A provided with an inner basket supporting frame E and a lower glass-washing arm F revolves when wash water is forced therethrough and will direct the wash water against the drinking glasses, not shown, for cleaning them.
- This structure forms no part of our present invention.
- a hot water pipe 25 extends upwardly and communicates with a rinse spray arm G that is rotated as the fresh rinse water, heated toabout l F., is sprayed upon the glasses for rinsing the wash water therefrom.
- the wash and rinse cycles may be manually controlled by the operator pressing the buttons in proper sequence or the glass-washing machine may have an automatic control that will carry through the two cycles in succession when once a starting button is depressed. Again; this phase of the glass-washing machine forms no part of our present invention illustrated in the form of the device shown in FIGS. 1 to4 inclusive.
- the drinking-glass or dishwashing machine is designed so that the top of the hood C wiil lie flush with the counter H of a bar where drinks are served, see FIG. 3.
- the hood-supporting member 8 would form a part of the front of the bar and the bartender would have access to the washing and rinsing compartment of the device from his side of the counter when the three-sided door D is moved downwardly into the wash water tank A by means of the handle 5.
- the operator raises the door D by means of the handle 5 to close the compartment and then presses the necessary buttons to cause the machine to wash and rinse the glasses.
- the counterweight 24 will keep the door closed.
- the operator lowers the door D into the wash tank to open ihe washing and rinsing compartment and permit the removal of the washed and sterilized drinking glasses.
- the principal difference lies in providing a device in which the door D will be held in closed position during the successive washing and rinsing cycles and then at the completion of the rinsing cycle, the door will be automatically unlocked and will move into open position and the device will shut itself off and cease operating.
- the mechanism for accomplishing this includes a solenoid-actuated lock arm J that is shown in unlocked position in FIG. 5 and in locked position in the fragmeritary illusiration of a part of the modified form of the device in FIG. 9. Also, the weight 24' shown in FIGS.
- FIGS. 5, 6, 8 and 9 show the three-sided door D provided with a keeper K that is in the form of an inverted U.
- the keeper is placed at the upper edge of the side panel 9' of the door.
- FIG. 9 shows that when the door D is in closed position, i.e., when the door is raised, the lock arm J can be swung clockwise into a locked position and will engage the keeper K and prevent any downward movement of the door into open position.
- the lock arm J is secured to a rockable shaft 50 that in turn projects from a housing L.
- the housing is shown mounted on top of the hood C, but it could be mounted on the hood support B so as to be below the top of the hood.
- the operator may manually raise the door D to close it and then may press one of the starting buttons to cause the machine to go through its washing and rinsing cycles automatically.
- the starting of the washing operation will energize a soienoid, not shown, for swinging the lock arm in a clockwise direction from the freed position shown in FIG. 5 into the locked position where it engages with the keeper K as shown in FIG. 9. It is possible to have the manual ciosing of the door actuate the starting switch and thus lock the door in closed position.
- the door D wiil remain iocked and closed until the washing and rinsing cycles are completed, whereupon the machine will stop operating and the solenoid, not shown, will be deenergize cl andggermit the lock lever J to swin by gravity into open position. ince the weight of the door is greater than the counterbalancing weight 24, the door will move downwardly into open position by gravity. in all other respects the modified form of the device operates the same as the preferred form and no further description is necessary.
- the housing L contains a timing mechanism similar to the one described in our US. Pat. No. 3,246,938. Instead of the door-actuated starting switch illustrated in FIG. 10 of the patent, any type of starting switch could be used.
- a drinking-glass or dish washing machine comprising:
- a vertically movable door normally closing said compartment, said door being movable downwardly into said tank for opening the compartment and permitting access thereto for the insertion or removal of drinking glasses and the like.
- the washing compartment includes a hood for covering the top of the compartment and a support for the hood that extends between the hood and said tank and forms one wall of the compartment;
- said door having three sides that cooperate with said hood and the support therefore for forming a closed washing compartment when the door closed.
- door-guiding means carried by said two side panels and cooperating with guides on said hood support for guiding said door in its movement between closed and open position and vice versa.
- said hood having a time-controlled means for swinging a lock arm into engagement with said keeper when the door is moved into closed position for keeping said door closed for a predetermined time period;
- said time-controlled means swinging said lock arm out of engagement with said keeper for freeing the door at the termination of the time-controlled period.
