WINDOW FOR LOCOMOTIVE-CABS.

SPECIFICATION forming part of Letters Patent No. 586,896, dated July 20, 1897.

Application filed May 20,1895. $eria1 No. 549,890. (No model.)

To ctZZ whmn it may concern:

Be it known that I, WILLIAM P. F. CARROLL, a citizen of theUnited States of America, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in WVindows for Locomotive-Cabs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to' make and use the same.

My invention relates to improvements in windows for locomotive-cabs, and specially to windows designed to project from the side of the cab and to be capable of being folded up, both walls and top and bottom, when not in use.

It consists in the combination, with the side of a locomotive-cab, of laterally-folding window-sash having glass therein and a top and bottom for the same capable of being turned vertically on suitable hinges.

It further consists in the use of springhinges for the sash, means for regulating the angle of elevation of the top, and means for securing the sash and top and bottom in position.

It further consists in certain details of construction which will be hereinafter fully described and claimed.

In the drawings herewith accompanying and forming a part of this application, Figure my improved. window attached thereto. Fig. 2 is an end View of the same. Fig. 3 is a horizontal sectional View of Fig. l on line 00 50.

line y y, the sash being omitted. Fig. 5 is a detail plan of the spring-hinge, and Fig. 6 is a sectional detail showing hood in position.

Same letters refer to like parts.

In said drawings, 0t represents'a side of a locomotive-cab, and b and 0 windows therein. Attached to the side of the cab on either side of the window 0 are folding sashes d e and f g, d and f being attached-to the sides of the cab and e and g hingedto d and f, respectively, substantially as shown in Fig. 3, the dotted lines showingthese parts when not has glass set therein, through which the engineer can see forward or backward or laterally, as desired.

The hinges which connect the sash with the side of the cab and with each other are springhinges which may have the form shown in Fig. 5, in which it represents ears attached to the side of the cab or sash, as the case may be; i, an ear attached to the corresponding or adjacent part of the cab or the sash, respectively, j, a journal set in said ears, and k a coil-spring arranged on said journal in such manner that it tends automatically to bring the two parts together. The car i has a lug Z thereon, under which the end m of said coilspring rests.

It will be seen that the part i can be readily removed from the other part, so that the swinging parts of the window can be quickly taken off or put on.

The top or hood n is hinged above the sash to the cab in such manner as to be adapted to turn vertically, and its angular elevation may be regulated in any convenient manneras, for example, by means of a link 0, pivotally attached to said hood and to a slide 19, arranged on the track q, attached to the side of the cab or window and held in any required position on said track by means of a setscrew 4.

It will be seen that as the window is raised or lowered the link forces said slide upwardly or downwardly, as the case may be.

It will be evident that when the sash are turned back in the position shown in Fig. 3 the hood may be lowered to any required elevation to serve as an awning to keep the sun from the eyes of the engineer.

I also hinge the bottom or sill s to the cab, or the sill maybe composed of two parts, one, 25, being removably secured to the side of the cab, as seen in Fig. 4, and the other hinged thereto by a hinge u. v The bottom of the sash has lugs o, projecting downwardly, and the sill has spring-plates w, attached thereto and adapted to engage the lugs on the bottom of the sash, as seen in Fig. 1, when the sash and bottom are in position.

To protect the glass from becoming covered with sleet in the case of snow-storms, I place over the window a hood 00, having substantially the form of an awning, but not extending downwardly quite to the bottom of the glass, so that a narrow horizontal opening is left, through which the engineer can see, the hood extending out suiiiciently far to serve as a protection to the lower part of the glass, as seen in Fig. 1, the inclined portion of the hood being shown in dotted lines and the open space being marked 3 The operation of my improved cab-window is as follows: hen the window is to be placed in position, the bottom or sill is raised horizontally to the position shown in Fig. 4E and the top raised above horizontal. The sash are then drawn outwardly and together into the position shown in dotted lines in Fig. 3, where they are held in position by means of the lugs in the sash engaging the socket in the plates attached to the bottom, as shown in Fig. 1. The top is then drawn down upon the sash, the whole having the positions shown in Fig. l. \Vhen notin use, the springplates are detached from the lugs and the springs force the sash back into the position shown in Fig. 3. The sill is turned downwardly and may be held by engagement with the spring-plate (0, attached to the cab below.

It will be evident that the sash may be folded back and the bottom turned down and then the top be arranged at any convenient angle to protect the engineer from the rays of the sun, adding to the comfort of the engineer and the safety of the train in consequence thereof. hen the sash, bottom, and top are in the position shown in Fig. 1, they form a complete shield for the face and eye of the engineer and at the same time permit him to lean outwardly beyond the edge of the cab, so as to be able to see forward and back on the line of the track.

Having thus described my invention and its use, I claim- In a folding cab-window, the combination with the sectional sash having spring-hinges designed to normally hold same closed, the lugs carried at thelower ends of the sashsections, of the hinged sill, the a-pertured spring-plates in which the said lugs are adapted to engage to hold the sash open, of the top N hinged to the cab and having a rim about its free edge designed to fit over the upper ends of the sash-sections when opened, to cooperate with the said lngs and spring-plates, to lock the window open, all substantially as shown and described.

In testimony whereof I affix my signature, in presence of two witnesses, this 7th day of May, A. D. 1895.

\VILLIAM P. F. CARROLL.
