STORMWINDOW FOR LGCOMOTIVE-GABS.

Application filed April 26,

1- GLsNnr United in the county of Marion and State of Indiana, haveinvented new and useful Improvements in Front Storm-Windows for Locomotive-Cabs, of which the following is asgecification.

This invention relates to means for retaining glass lights in storm windows. for loco motive engine cabs. Heretofore these have commonly been held in their iron frames or sashes by plaster of Paris, used instead of putty becauseof the hardness and difiiculty of removing thelatter to replace broken lights. The lights are broken frequently and under the rules followed by locomotive engineers the latter will refuse to take out an engine with, a broken storm glass but will hold the engine idle until the-broken light has been replaced with a whole one. The resulting delay frequently causes disarrangement of the train schedules and much loss and damage to the railroad. The object of our invention is to retain the" glass in its frame or sash by a spring means which will afford quick and easy removal of broken lights and the insertion of new ones, and which will hold the glass panes securely in place and prevent rattling.

We accomplish the above and other objects which will hereinafter appear, by the mechanism illustrated in the accompanying drawing, i'n whichv 35, Figure 1, is a perspective view of a cab window with a storm light partly open. The light is secured by a spring means in accord ancegwith the teachings of our invention. Fig. 2 is a perspective view illustrating the 4 0- manner of insertion of a new light. Fig. 3

.is a vertical section of a frame with the light in place and held by our improved means and Fi .{i is an edge view of one of the springs removed from the other parts.

The storm windows of locomotive engines are located in a door which affords eg from the cab to a running-board at the side of the engine; consequently it is more than ordinarily subject to injury by the passing. of the engineer in and outthrough the narrow. penin and to slamming of the door,

and it is a so important that the glassy be kept whole because the View of the track ahead is through it and if the glass be broken to the 'rush of air caused by the speed of the crossing to the inner Specification Letters Patent. Patent d N 30 1926 1920. Serial No. 376,772.

train throws 'a iusilade of cinders and dirt or of blinding rain or snow into the en gmeers eyes.

In the window-opening of door 5 are generally two glass lights 6 and 7'. The light 6 is a fixed one while the light 7 is capable of a swinging outward adjustment to various angles to provide a sight opening below when rain or snow on the glass would obstruot the view.

This light 7 is mounted in an iron frame or sash comprising a top horizontal member 2%. and vertical ends 9, 9. There is no horizontal lower fra me member because one there would obstruct the view and for that reason it is omitted, and because of such omission the glass is unsupportedthere and is therefore much more easily broken. The ends 9, 9, are angle bars, and the horizontal bar 8 is channeled, the channel forming upper edge of the glass, and, to direct and wedge the edge into place the top flange 10, of the channel is beveled on the side toward the lass. in the manner shown in Fig. 3.

The sash thus filled is hinged at its upper edge in an iron'frame ll, in turn fixed to the door 5. The frame 11 has an ear 12 with a pin 13, and the adjustable window sash has a. rack-bar 14, the series of notches in which maysuccessively be made to engage ping13, and hold any given elevation of the swinging sash. This much of theconstruction is old with the exce tion beveled flange 10, t 1e glass having heretofore been secured in members 8 and 9, 9, by plaster of Paris.

The novel feature of greatest importance in our invention is the use of springs to" clamp and'retain the glass in the Inn ed frame. purpose may be used and have been used by us, but the best embodiment so far known drawings which is in duplicate ,-onq-I,f or each end member 9, 9, and which is filial! spring having a member 0' to lay against the opposite or outer side of the end member from the glass, to which it is fastened by a stove-bolt 15. "'The member a is continued at right angles, with or without rounded corners, to form the membegob side of the sash, and thence in. a return direction substantial parallel with member a to form the member 0, which preferably extends past the boll:

a seat for the of the channel and Various forms of spring for t to us is that substantially as shown innthe l5 and is bowed toward the glass to secure extended and positive contact with the latter, in the manner shown in Fig. 3.

.To insert a glass pane the springs on both ends of the sash are sufficiently flexed to raise the loose member '0 clear of the frame,

and thereupon the ends 5 are swung outwardly around bolts 15, to positions shown in Fig. 12, leaving the way clear for the edgewise introduction of the glass in the manner shown in Fig. 2; and when the glass is placed the springs are both turned back to first position across the edge of the glass with the members 0 pressing against the sides of the glass and holding the latter to the sash.

'ith our improved means an engineer may carry extra panes of glass with him and can replace a broken light himself in a few seconds, whereas under old conditions it was necessary to send the engine to a shop or bring an expert workman from there to do the job, -ausing delay in either of the last cases.

Ye do not desire to be limited to the form and application of spring here shown, nor to the construction of the sash which is mainly the same as has been heretofore used and not as well adapted to our means as would obtain it specially designed; but What we do claim as new and wish to i are by Letters Patent ot the United States, is

1. The combination in a locomotive engine cab and a storm-door therefor, of an upper sash swingingly mounted in the door, a glass supported by the sash, and spring glass against the means for retaining the glass in the sash each spring having a portion pressing the sash and another portion secured to the opposite-side of the frame from the glass.

The combination in a locomotive engine cab and a storm-d0 r therefor, of a sash open at the bottom and swingingly mounted in the door, a glass supportedby the sash, and spring means for retaining the glass in the sash, each comprising portions pressing the glass against the sash and other portions secured to the opposite side of the frame from the glass.

3.In a devlce tor the purposes HpQIlilNl.

a sash open at the bottom, a glass supported by the sash, and a leaf spring bent in U shape having one stem pressing the glass against the sash and the other stem ally secured to the opposite side of the from the glass.

at. in a device for the purposes specii'ied, a sash having a top horizontal channel bar frame with an inwardly beveled outer flange, said sash having no lower rail, a glass supported by the sash, and spring means for retaining the glass in the sash.

5. In a device for the purposes specified, a sash having a channeled top rail the channel being inwardly beveled and said sash having angle'bar side rails a glass in the sash and spring means for retaining the glaSS.
