UNITED STATES PATENT OFFICEe GEORGE MANN, JR., OF OTTAWA, ILLINOIS.

IMPROVEMENT-IN WINDOWS Foa RAILROAD-CARS.

Specification forming part of Letters Patent No. 4 1,079. dated January 5, 1864.

To aZZ whom it may concern: l Be it known that I, GEORGE MANN, Jr., of Ottawa, in the county of La Salle and State of Illinois, have invented a new and useful Improvement in Windows for Railroad-Cars, and which improvement; I term a Detlecting Car-Window; and I do hereby declare that the following isa full, clear, and exact descrip- -tion of the same, reference being had to the accompanying drawings, making a part of this speciiication', in whichj Figure 1 is a vertical section of my invention, taken in the line .t tr, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in having` the frame of the car-window hung oir central pivots and arranged in such a manner that it. may be adjusted in an oblique position relatively with Athe car-body, so as to deect dust, cinders, &c., from the car while the same is in motion, and at the same time admit of a passage of air out from the car, and also admit of being so adjusted as to cause airyto' enter the car through the window when there is no dust to contend with.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a portion of one side of a car-* body, and B the opening over which the win dow is placed. C C are two horizontal projecting pieces which lare attached tothe side A of the car, one being at the topand the other at. the bottom ot''the opening B. These pieces C C may project, say, from four to six inches out from the side ofthe car.

D represents the window-frame ot square form and having a glass, E, tted into it. This frame is provided with a. central pivot, a, at its top and bottom, and said pivots are fitted loosely in the projecting pieces C C', so that the frame D may be turned between them.

To the lower projecting piece, C', there is attached a segment-rack, F, into which an elastic bar, G, which is attached to the lower end ot' the frame D, catches, the bar G, in consequence of catching into said rack, serving to secure the frame D in an oblique position relatively with the sideA of the car and in two opposite oblique positions, as shown clearly in Fig. 2, one of said positions being shown in red.

The opening B is providedl with the ordinary car-window, which is not shown iu the drawings.

Ihe pivots a`are fitted in the plates G C a-t such a distance from. the side A `that when the frame D is turned or adjusted in an ob-l lique positiollone edge of 'the frame will be in contact with one side of the opening B, as shown in Fig. 2.

In order to use my invention, the inner or ordinary window is raised, and the outer windowv or frame, l), adjusted in an oblique position so that the open `space will be behind or face the .back end of the car and the closed endl facev the front end of the car, as shown in black in Fig. 2, the black arrow indicating the direction ofthe movement of the car.

-By this means the dust, cinders, &c., are deiiectedby the glass E out from the carbody, while a current of air will be allowed to pass out from the lcar through the open end at the back of frame D, as indicated by the dottedarrows. When the car is mdving'in the opposite direction, the frame D is adjusted in the reverse position. (shown in red in Fig. 2.)

At any time when there is no dust to contend with, the frame D may be so adjusted as to have its open end facingl the front ofthe car, so that air will be forced into the. latter as it is propelled along. The frame D may may also be adjusted parallel with the car- Window to allow the air to pass between when D is not required as a deiiector.

, Having thus described my invention, what I claim as new, and desire to secure byLet ters Patent, isv

The supplemental window attached to the side of the car at the exteriorvot' the ordinary or usual window, in the manner substantially as herein described, to admit of the adjustment of the supplemental window in au oblique position relatively with theside of the car, asand for the purpose specified.
