HOLLIS W. TINKER, OF NASHUA, NEW HAMPSHIRE, ASSIGNOR OF ON E-HALF TO FRED WV. TINKER, OF SPRINGFIELD, MASSACHUSETTS.

LOCOMOTIVE-CAB OR OTHER WINDOW OR DOOR.

SPECIFICATION forming part f Letters Patent No. 516,245, dated March 13, 1894.

Application filed April 20, 1893. Serial No. 471,172. (No model.)

T0 all whom t may concern:

Be it known that I, HoLLrs W. TINKER, a citizen of the United States, residing at N ashua, in the county of Hillsborough and State of New Hampshire, have invented certain .new and useful Improvements in Locomotive-Cab or other Vindows or Doors; and I do hereby declare the following to be a full, clear, and exact description'of the invention, such as ro will enable others skilled in the art to which it appertains to make and use the same.

My present invention is an improvement on the locomotive cab window or door, or pilot or light house window or door, or store window or door, for which I tiled an application for a patent on October 3, 1892, Serial No. 447,717, audits object is, while it shall afford all of the benefits derived from the invention set forth and claimed in said application,

zo it shall also avoid rthe inconveniences arising from the glare of the glass panes. My present invention causing, (by reason of the density and transparency of the water or other analogous transparent heavy body of duid;

and of the same being a good conductor of heat, and entirely filling the space) a double glazed window, which has a chamber between its panes, to appear like a solid or single glazed window, and to reflect the light in the 3o same manner as it is by a window glazed with a single pane.

My invention consists in a locomotive cab, pilot, light house or store window or door which is doubled glazed, has a tightly packed chamber between its panes of glass and has the space or chamber between its panes filled with clear water or other analogous transparent heavy fluid, and is furnished with means for heating the contents of the chamber. Sec- 4o ond in certain novel combinations and details of construction as will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a section of a locomotive cab, and an end elevation of aboiler, and an end elevation of my invention applied to the door of the cab and connected to the boiler. Fig. 2 is a vertical section of the door with my invention applied thereto. Fig. 3 is a horizontal section of the 5o door with my invention. Fig. 4 is a horizontal section Yof a portion of the door and cab,

illustrating the means for latching the door open. Fig. 5 is a horizontal sectional view of the door and sash on an enlarged scale, showing a slightly different way of packing the glass panes or plates, and Fig. 6 is a detail view of the construction shown in Fig. 5.

A in the drawings designates a boiler;`B an engineers cab of a locomotive; C a hinged door of the cab, and D a quadrant latching 6o arm, and supports on which the door swings open, or closes. The hinged door is provided with a central sash frame E and two glass panes or plates F F. The sash frame comprises an oval or other analogous shaped metal frame portion a, having a central seat rib b; and two oval shaped clamping portions c c of corresponding form to the frame portion a. The glass panes or plates F F are placed against india rubber or felt packing 7o pieces clapplied respectively on the respective sides of the `seat. It is beneficial/to place pieces of tin-foil, thin lead, or paper, as e between the glass and india rubber, in order to prevent sticking of the rubber to the glass, as illustrated in Fig. 5. The clamping portions c,|c, are screwed, as indicated at f, to the inside-and outside surfaces of the sash frame, and between them and the glass panesor plates, rubber packing g, is applied, the 8o samel resting, preferably, against tin-foil, lead or paper as e applied on the seat of I/Vhen the panes or plates of glass are thus applied and'clamped water tight by the portions c, c,

a space G for holding water is provided between the glass panes or plates as shown. Above the panes or plates of glass a hopper shaped Water supply-receiving chamber H is provided, the same being in communication bya passage h, with the water space H. This 9o box has a lid i and in this lid safety vent holes'may be provided. Below the panes or plates of glass achamberj is providedon the sash frame, and the same is in communicaltion, by a passage lo, with the water space H.

This chamber may be elongated and widened, and have a space below and between it and the wood of the cab door, for the introduction vof a gasoline burner, or any other suitable heating means; and if this construction is Ioo adopted, the water in the chamber and space H will be heated by the gasoline burner or a lamp. But I have shown as the preferable means for heating the water, a steam pipe I connected with the steam boiler A. This pipe extends through the chamber j at one end and out of it near its other end. Near the boiler a cut off or regulation cock .I is applied on the steam pipe, and near the window another cut oft or regulation cockK is provided; and at the end of the pipe a drain cock L having a rubber pipe L for conducting away water ot' condensation is applied. By means of the cock J the steam may be cut off entirely or partially at points remote from the window, and thus all danger can be averted, or the amount of steam supply can be regulated; and by the cock K the quantity of steam supply can be controlled from a point near the cab Window. In the bottom of the chamber] a drain cock M is provided for conducting away foul water from the space I-I and chamber j as necessity may require. The steam supply pipes between the window or door, and the boiler, may be of metal and provided with an ordinary packed gas pipe joint m, which will permit the door to open and close, or the connection between the regulation cocks J, K, may be made ot' india rubber.

By my invention of a Windowhavingabody of Water between its panes, and of means for confining a body of clear Water or other suitable fluid between the panes or plates of glass and heating the same, many advantages over devices which simply heat air ina space between the panes or plates of glass are secured, to Wit: The double glazed window has the appearance of a solid or single glazed window; the glare of' the glass and the imperfect reflection of the light are avoided; the panes or plates of glass are strengthened by the backing or solid mass of water, and, withal, the window is kept free from snow, ice and sleetin stormy weather, and engineers and pilots are afforded a clear lookout for dangerous obstructions ahead.

I contemplate dispensing with the chamber j below the panes of glass, and simply to enter the steam heating pipe into the water `space between such panes and extend its discharge end outside of the window or door, and myinvention is intended to embrace such construction as an equivalent of the one described and shown.

What I claim as my invention isl. A window or door composed of two panes of glass set apart, and having the intermediate space filled with a heavy transparent fluid, suitable means for confining the fluid within the chamber, and suitable means for heating the fluid, substantially as and for the purpose described.

2. The combination of the sash frame, two panes of glass elastic packing applied upon the seats of the sash frame, clamping portions, a body of' heavy transparent fluid confined between the panes or plates of glass, and suitable means for heating said body of Huid, lsubstantially as and for the purpose described.

3. A window or door for a locomotive cab, and other purposes, comprising separated panes or plates of glass with a fluid tight space between them, and a body of heavy transparent fluid between the glass panes or plates, means for' heating said fluid, and ahinged pipe connection, substantially as described.

Ll. A hinged window or door for a locomotive cab or other purposes, comprising separated panes or plates of glass with a fluid tight space between them, and a body of heavy transparent fluid or other analogous heavy fluid between the panes of glass, means for heating the Huid, hinged pipe connection and a quadrant latching` arm and supports, substantially as described.

In testimony whereof I hereunto affix my signature in presence of' two witnesses.

HOLLIS W. TINKER.
