ALEX MINTZ, or` NEWy Yoan, N. Y.
COFFEE-MAKING APPARATUS.
To all lwhom t may concern.'
Be it known that I, ALEXMINTZ, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Coffee-Making Apparatus, of which the following is a full, clear, and exactdescription. f
My invention relates to a coffee-making apparatus and has reference more particularly to an apparatus wherein the coffeepots are heated by hot water supplied from a boiler which is external to the coffee-pots and whereby'economy of burners and, therefore, of fuel is obtained. The object of the invention is to provide a simple, inexpensive and efficient coifee-makin'g apparatus in which the coffee-pots are heated by water confined in a jacket at the bottom of the boiler and which water is caused to circulate about the coEee-urns and maintain the same hot.
INith the above and other objects in view,
the nature of which will more fully 'appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming `part of the application, similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a section of a coffee-making apparatus embodying my invention, a portion of the boiler being shown in' elevation; and
Fig. 2 is a perspective View, partly in Vsection, ofthe unit forming the water-jacket and the insulating chamber. Before proceeding to a more detailed description of my invention it must be clearly understood that the subject matter of this invention is an improvement over my Patent No. 1,167,199 issued January 4, 1916, and it differs therefrom by the provision of a thermoinsulating chamber between the jacket and the boiler, of'means for filling the jacket with boiling water directly from the boiler, and of a pot for boiled water.
Referring to the drawings, 3 is a vertical boiler of customary construction, the bottom 4 of which is dished and forms, preferably, part of a vcasting 5 secured in any suitable way to the boiler. The casting has an annular water-jacket 6 which is spaced Specification of Letters Patent.
Patented Mar. 6, 191'?.
.Applicationl filed March 1, 1916. 'Sera1No. 81,381.
from the sides of the dished bottom 4 by i an annular chamber 7 which may be filled, if desired, with mineral wool or any other material which will increase the insulation. It will be noted that the water in the boiler 3 is heated in the central part of the bottom by a burner` 8, the flame of which acts on the bottom of the casting and also on the jacket. I y
A valve-controlled conduit 9 leads to the main to supply the boiler. A valve-controlled vconduit 10 is provided near the bottom of the boiler'and it connects the boiler with a conduit 11 extending from the acket and connected to a valve controlled conduit 12 adapted. to supplyboiling water from the boiler to said conduit 11. l
The jacket 6 is jconnected to a coee-pot 13 by a conduit 14 and a conduit 15 above the conduit 14. By means of the conduit 14 the coffee-pot canbe lilled with water from the boiler 3 through the jacket 6. The conduit l5 connects the upper portion of the co`eepot with the;jacket; and when the water in the jacket is heated, a circulation of hot water is established from the jacket hotwater circulation is established in the.
coffee-pot connected with the jacket and' whereby the coffee in the urn can be maintained hot without applying heat directly to the coffee-pot as is customary. By this means only a single burner is utilized to maintain one or more coffee-pots hot. The jacket 6 at the bottom of the boiler being of comparatively small capacity it gets hot quickly and facilitates the circulation-of hot water from the jacket through the coifeeot. i p It is often desirable to maintain the level of the water in the coffee-pot above that in the boiler. This would be impossible by means of the valve-controlled conduit 10, for it would only permit a common level within the Apot and the boiler. Further, it is very often desirable to transfer boiling water from the boiler into the coiee-pot without permitting the hot Water from the coffee-pot to circulate in the boiler. rIhis cannot be accomplished through the medium of the valve 10, and for that purpose the valvefcontrolled conduit 12 is used. When the Water is boiling in the boiler 8, the valve-controlled conduit 10 being maintained closed, and the valve-controlled conduit 12 being open, the boiling Water from the boiler Will pass into the jacket from Where it Will pass into the boiler. This Will not only permit the transfer of boiling Water into the pot 13, but it also permits a higher liquid level in the pot than in the bo-iler.
vThe thermoinsulating chamber 7 prevents the cold water admitted into the boiler 3 through the valve controlled conduit 9 from chilling the hot water in the jacket 6 and thus cooling the coffee-pots.
The valve-controlled conduit 12 has a va ive-controlled extension 1S leading to a pot 19 forming thc top of the boiler 3 and to which pot boiling water is supplied from the boiler. A dispensing, valve-controlled conduit 2O is provided for the pot wherefrom the Water can be drained for any purpose, as, for example, when making cocoa or tea. rIhe boiling water in the pot 1s maintained hot by a hot-Water coil 21 located Within the pot and connected by conduits 22 to the jacket. This arrangement permits a restaurant keeper to have a reserve of hot boiling Water. l
Vhen-Water is boiling in the pot and the valve-controlled extension 18 is open, While the valve on the conduit l2 and the valve on the conduit 10 are closed, the pressure Within the boiler forces the Water from the boiler into the pot; and VWhen sufficient Water has been driven into the pot from the boiler the valve to the extension 18 is closed.
The circulation through the coil 21 is due to the fact that the conduits 22 are connected to the jacket `at different heights, and in view of this, there is bound to be circulation through said conduits and, therefore,
through the coil.
lhile I have described the principle of operation, together` With the apparatus which I now consider tobe the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made as are Within the scope of the appended claims.
