W. M MlNNlS RAILROAD ENGINEMENS CLEAR VISION WINDOW 2 Sheets-Sheet 2 Filed March 18, 1943 Inventor Patented Jan. 30, 1945 UNITED STATES PATENT OFFICE RAILROAD ENGINEMANS CLEAR VISION WINDOW William McMinnis, Elkhart, Ina. Application March is, 1943, Serial No. 479,628 3 Claims. (01. 20-40) The present invention relates to new and useful improvements in engineniens clear vision windows for railroad engine cabs, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising a novel construction and arrangement whereby various sizes of clear vision openings at different elevations or positions may be conveniently had.

Another very important object of the invenand side members-5 and 6 are formed to pro vide channels or grooves 1 for receiving vertioally slidable panes 8 which are removably tion is to provide, in a clear vision window of I pact, and which may be manufactured at lowcost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of a window constructed in accordance with the present invention mounted in position on a railroad engine cab.

Figure 2 is a view in front elevation of the window, showing two of the panes elevated to provide a clear vision opening.

Figure 3 is a view in vertical section through the window.

Figure 4 is a view in horizontal section, taken substantially on the line 4-4 of Figure 2.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a frame of suitable dimensions and material which is desi nated generally by reference numeral l. The

extensions 9.

mounted in the frame. The'side members 6 of the frame I include extensions 9 on their upper ends which project above the member 4.

Vertical rodsiil are mounted on the side por tions of the frame i inwardly of the latter. Brackets II on the frame, I receive the end portions of the vertical rods l0. comparatively large and small plates l2 and I3, respectively, are mounted for sliding and swinging movement on the rods Ii].

beneath the lowermost of said panes, include eyes I4 which are rotatable and slidable on the rods in.

It is thought that the manner in which the window functions will be readily apparent from a consideration of the foregoing. Briefly, when in the position shown in Figure 1 of the draw- If a clear vision opening is desired, however, it is only necessary to elevate one or more of the panes 8 and engage either or both of the members l2 and I3 therebeneath, as suggested in Figure 3 of the drawings. It will thus be seen that the opening may be had at substantially any desired elevation and, further, the comparatively large and small plates I2 and I3 permit openings of different sizes to be had. The channels or grooves I are open at the upper ends of the side of the cab;

It is believed that the many advantages of a railroad enginemens clear vision window constructed in accordance with the present invention will be readily understood, and although a preferred embodiment ofthe device is as illustrated and described, it is to be understood that changes in the details of constructionand in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A railroad enginemens clear vision window comprising a frame, a plurality of panes mounted for vertical sliding adjustment in said frame, vertical rods mounted on the frame, and members pivotally and slidably mounted on the rods and engageable selectively beneath or between the panes for providing an unobstructed opening in the window at various elevations.

The plates l2 and I3.- which are engageable between the panes 8, or

This permits the panes 8 to be readily removed for cleaning from the inside 2. A railroad enginemens clear vision window comprising a frame including top, bottom and side members, said side members including extensions projecting above the top member, the bottom and side members having channels there in open at their upper ends, a plurality of panes mounted for vertical sliding adjustment in the channels, vertical rods mounted on the side portions of the frame, and a plurality of plates mounted for swinging and sliding movement on the rods, said plates including eyes journaled on the rods, said plates being engageable selectively beneath or between the panes for providing an unobstructed opening in the window at various elevations.

3. A window comprising a grooved frame providing a window opening, a plurality of more than two horizontally elongated panes vertically slidable in said frame and independently movable to selectively provide a space between any two adjacent pane or between the lowermost pane and the bottom of the frame, said panes being in the same vertical plane and normally -disposed in edge-to-edge abutting relation to close the window opening with the lowermost pane resting in the bottom of the frame, vertical guide rods mounted on and extending from top to bottom of the frame at opposite sides of the latter, and a pair of superposed independently movable prop members of different heights slidabl and pivotally mounted on each guide rod, said prop -members being vertically adjustable and selectively swingable horizontally to project between the opposite ends of the panes or between the ends of the lowermost pane and the bottom of the frame, whereby a space of either of the diiferent heights may be selectively provided at the topor bottom or intermediate the top and bottom of the frame.
