DUST-GUARD FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 337,999, dated March 16, 1886.

Application filed August 19, 1885. Serial No4 Q7-1,794. (No model.)

To all whom it may concern:

Be it known that we, JAMES C. SLAETER and ADLER C. CLAUSEN, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Dust-Guard for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a perspective view of our improved dust-guard. Figs. 2 and 3 represent detached plan views of the opposite sides; and Fig. 4. is a side view showing the device folded. Y

Our invention relates to devices for preventing theentrance of smoke, cinders,sparks, &c., through an open window of a railwaycar or other vehicle; and our invention consists, essentially, in a dust guard composed of sections hinged or sliding together and capable of being folded into a small space, thereby enabling` it to be carried in the pocket. It also consists in suitable buttons or cams, which secure the device to the window, and by means of which it may be readily removed, all of which we will hereinafter fully describe, and specifically point out in the claims.

To enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and the manner in which we have carried it out.

In the said drawings, A represents a railway-car window, and B our improved dustguard. This guard is composed in the present case of three sections, a, b, and c, hinged together at d and e, whereby when not in use the sections may be folded one upon the other, as shown in Fig. 4.

Owing to the small space occupied by the guard when not in use it becomes a matter of great convenience to the traveling public, and being composed of some light suitable material, its cost is but a trilie, while it may be adjusted to the windows of any railway-car without trouble.

It will be observed the sections a and c have their surfaces cut at an angle at tt, and are also provided with notches e. This construction is for the purpose of holding the window when required, the bottom rail of the sash resting in the upper notch, and the lower inclined face of section c resting on the sloping sill of the car-window, and also for making the guard reversible.

Each of the sections a, b, and c is provided with buttons or cams g, which engage the groove in the side of the window-frame, and these cams have shanks h extending to the opposite side ot' the guard, whereby the occupant of the seat may, by a simple halfturn of the shanks, cause the cams to bear tightly against the window-frame, or, if in use, the guard may be removed by the saine operation.

The adjustment of the guard is accomplished by placing it against the side of the window-frame, so that the oval blocks or cams will it into the grooves in which the window slides. Then by turning the cams by means of the buttons shown in Fig. 3, the friction in the grooves caused by the blocks coming in contact therewith will hold the guard rigidly to its place. The guard, as shown in drawings, is made to fold together; but We do not limit ourselves to this construction, as the same may be made to slide together by means of grooves or runners. (Not shown.) `When the device is folded, one of the outer' buttons is placed so as to turn and lock over the end of one of the folded sections, as shown in Fig. 4, thus holding it together without the use of a string or band.

If it be desired, the sections may be bound or covered with metal, thus adding to its stiffness without materially increasing its weight or cost. A

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A dust-guard for car-Windows, consisting ofthe sections a, b, and c, each provided with a cam or button, g,whereby the sections may be independently secured to the Windowgroove, or be locked together when not in use, substantially as herein described.

2. A dust-guard for car-windows, consisting of the combination of the sections a, b, and c, the cams or buttons g, secured to each of the sections, and the shanks h, projecting through the sections and operating the cams, substantially as herein described.
