DUST-GUARD FOR LOCOMOTIVE-CAB- WINDOWS.

SPECIFICATION forming part of Letters Patent No. 458,939, dated September 1, 1891.

Application filed October 17, 1890. Serial K06681490- (No model.)

To all whom it may concern/.-

Be it known that I, FRANK O. BOND, of Port Jervis, in the county of Orange and State of New York, have invented a new and useful Improvement in Dust-Guards for Locomotive-Oab Windows, of which the following is a specification.

My invention is an improvement in locomotive-cabs, and particularly in the construction of the windows, so that the engineer and fireman will be protected from cinders, storm, &c., in looking forward, and so that the protecting window will not become clouded from the variations in temperature between the outside air and the interior of the cab.

The invention consists in certain features of construction and novel combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a perspective view of a part of a locomotive-cab provided with myimprovements. Fig. 2 is a horizontal section, and Fig. 3 is a partial side View.

In locomotive-cabs the heat causes the condensation of moisture upon the window-glass, resulting in the clouding of the glass or the formation of frost thereon, so that the e11- gineer and fireman can only see out by opening the windows. In winter this exposes them to the force of the wind and storm, while at all times they are exposed to the dust and cinders. By my invention I provide a protecting or guard window which may be readily adjusted into and out of position for use, may be rigidly secured in either of such positions, and will in both of its positions be free from the influences of the heat in the cab, so that it will notbecome frosted or clouded in use.

The cab A may in general respects be of ordinary construction, having the fixed forward windows B and the rear windows 0, the latter being supported to slide forward alongside the front windows.

In connection with the usual side windows 13 and C, I employ what, for convenience of reference, I term the guard window D, which is supported to turn when closed into the plane of the cab side or when opened out to a plane at right angles, or ap noximately so, to the said cab side, securing devices being arranged to hold the guard-door in both its open and closed positions. In the construction shown the guard-window has a frame (1, and is hinged at one edge I) to the cab side at the rear end of the fixed window B, so that when closed it will turn forward within the frame of the window B and rest flush with the side of the cab. A hinge-like fastening E is pivoted at e to the guard-window and has a hinged plate, which in the closed posi tion of the window fits under a catch E and has an opening to receive a pin E when the window is open. \Vhen opened, the guardwindow turns at right angles to the side of the cab and bears directly against the front end of the arm-rest F at the side of the sliding window C. This arm-rest forms a firm support for holding the guard-window when opened, such window being held open by means of the parts E E, as before described, or othersuitable securing devices.

In operation, if the guard window be opened, the engineer or fireman can at any time, by opening the sliding window C, look forward through the guard-window, being protected thereby from the wind, cinders, dust, &c., and such guard-window, being so arranged that it is exposed on both sides to the same temperature, will be kept free of frost or the condensation of moisture, by which it is clouded.

By my invention it will be seen that the guard-window may be set open and secured in such position, so that when the slide-window is opened the guard-window is ready for use. It will also be seen that the guard-window can be quickly applied to an ordinary locomotive-cab, requiring no change in the construction of the body of the cab or of its windows. Furthermore, the device is simple in construction and operation and possesses no parts likely to get out of order.

Having thus described my invention, what I claim as new is-- 1. The combination, with the locomotive cab having catch E and the arm-rest F, having pin E of the hinged guard-window and the fastening E, pivoted at e to the guard-window and having a hinged plate arranged, when the Window is closed, to fit in the catch E, edge to the cab side in advance of the armand provided with an opening arranged to fit rest and arranged to open at right angles to over the pin E when the Window is opened, the cab side and to bear when open against 15 Wherebysuch Window maybe secured in both the arm-rest, and securing devices by Which 5 its open and closed positions, allsubstantially the said guard-Window may be held in both as and for the purposes set forth. its open and closed positions, all substantially 2.
