j y To all whom 'itmayconfiere."k

Beit known' that I, JAMES J. DAVIS, a citi- Zen of the United' States, residing at Columbus., .in the county of `Franklin and State of Ohio, have invented certain new and useful Improvements in Means foi-vl7ar-miiig Show- I lVindows, f cation.y

of which the following is a specifif My invention relates to the improvement of means for warmingshow windows and the objects ofr my invention are to provide improved means for imparting to the innersurfaces of show windows, heat suflicient to prevent the formation thereon of frost or visible moisture ,to so construct my improved heating appliance as to provide an equal distribution ofthe heated air over the' window surfaces; to prevent the mixture of burned gas and heated air and to produce other improvements,"the details of which will be more fully pointed out hereinafter.

f These objects I accomplish in the manner illustrated in the accompanying drawing, in

which:` t

Figure 1 is la transverse section of a store-A .room` floor `showing the inner surfaces of store kkwindows withmy improved window warming mechanism in place, Fig. 2 is a secvshow windows or glass window plates, which tional -view on line `ach-.t of Fig. 1, Fig. 3 is a 'plan v iew of one of the heat distributing pipe retaining plates, and,fFig. v4r is a sectional viewon line 2 2; of Fig. 3.

Similar numerals refer to similar parts throughout'the several views.

`l represents the iioor of a store-room, 2 the forthe purpose of illustration I have shown y on opposite sides of a door 3, and 4 repre- .f l sents the window display iloors or platforms which ordinarily projectinwardly from the bases of ythe window frames which are indi cated at 2a.

an upright heater casing `rt which has the general form of a truncated cone and the lower end of which is open. zontally yinto, the casing r6, is a gas supply pipe 7 which carries centrally in said casing a 'perforated burner ring 8.'` Extending throug this ring and supported therein, is the lower end of a central vertical air tube 9, the upper end of which in the upper portion of the casing supports the upper end of a second or Extending hori-l intermediate substantially cone-shaped casing 10, with an opening in the upper end of which the tube 9 communicates. Leading horizontally outward from the upper portion of the casing lO'is an outlet pipe 11 provided with a suitable damper 12.

From the upper end oil the conical casing 6 lead upwardly and outwardly the desired number of heat conducting pipes 13, each of the latter being provided with a"` suitable damper 13a. Each of the pipes 13 leads to the central portion of a horizontal head or pipe section 14 which is located beneath the floor 1 and beneath the display platform of a window. From each of these pipes 14 lead upward through the iloor 1 and thence through openings in the display platform 4, a plurality of comparativelyl small pipes l5. The openings in the windowplatforrn through which the heat distributing pipes 15 lead, are arranged in a longitudinal ro'w at intervals one from the other adjacent to the inner side of the lower window frame bar 2a and that portion of each of the distributing pipes 15 which projects through the platform, iits within the central opening of a suitable me* tallic plate or disk 16 which is screwed or otherwise secured to the upper surface of the platform 4.

In operation, it will be understood that when the gas is lighted at the openings of the burner 8, the heat generated thereby will operate to heat the tube 8 and the outer and inner casings 6 and 10, with the result that the air which will be drawn upward between said outer and inner casings will become heated and will pass outward through the pipes 13' that any tendency of moisture to accumulate' on the window glass through condensation occasioned by the warmer air of the interior o'l` the store coming into contact with the colder glass, will be obviated. In this manner it will be understood that show windows may be kept clear of obstruction and in a desirable transparent condition.

Owing to the provision in the heating a1pparatus of the internal casing 10 and t e outlet 11, it will be understood that the lIO burned gas or products of combustion which may arise from the burner, may pass out- Ward Without becoming mingled With the heated air which passes through the external casing and through the tube 9. Although I have shown a gas burner in connection with the heating device, it is obvious that other means of heat generation may be employed.

WV hat I claim, is:

l. In a show Window Warming means, the combination of a heat generator and casing supported beneath a store-room floor, heat pipes leading upward therefrom, and horizontal pipe sections connected with the discharge end of said heat pipes, of a plurality of Vsmaller heat distributing pipes leading from said horizontal pipe sections to points on the inner side of and adjacent .to the bases of display Windows.

2. In a show Window Warming means, the combination With a heating appliance supported beneath the floor of a store-room comprising separated external and internal casings, said internal casing having an outlet in its upper portion, and heat generating means in its lower portion, heat pipes leading upward from said outer casing, horizontal pipe sections connected With the upperends of said heat pipes, and a plurality oi' smaller heat distributing pipes connected with each of said horizontal ipe sections, said heat distributing pipes Aaving their outlets adjacent to they inner sidesfof the bases of the store windows.

3. In a show Window Warming means, the combination with a heating appliance supported beneath the iloor of a store room, of an enlarged horizontally disposed heat pipe, a heat conducting pipe leading from said heating appliance to Vsaid heat pi e, said heat pipe being also located beneath t e floor, and i Va plurality of smaller pipes rising from said heat pipe and passing through the iioor of a show Window.

4. In a show Windowv Warming means, the combination with a heating appliance supported beneath the iloor of a store room, of an enlarged horizontally disposed heat pipe, a heat conducting pipe leading from said heating appliance to said heat pipe, said heat pipe being also located beneath the iioor, a plurality of smaller pipes rising fromsaid heat pipe and passing through the floor of a show Window,`plates into Which the upper ends of said pipes project, said pipes being located on top oi the show Window iioor, and means for securing said plates to said iioor.

5. In a device of the character described, the combination With a shoW Window, .of a heating appliance supported beneath the Hoor of a store room in Which said show Window is located, said heating pipes comprising se arated external and internal frustoconicacasings closed at their upper ends and open at their lower ends, a tube )assing from the inner of said casings, an out et pipe leading from the upper portion oi' the inner olA said casings, a burner located in the inner oi' said casings and supporting said tube, a heat conducting pipe leading from the upper portion of the outer casing, an enlarged heat pipe to which said heat conducting pipe is connected, a damper in said heat conducting pipe, and a plurality of smaller pipes extending from the enlarged heat pipe to and through the floor of the show Window.

In testimony whereof I ax my signature in presence of tWo Witnesses.

JAMES J. DAVIS.
