WILLIAM J. MCGRATH AND MARTIN H. SOHEFFT, OF CLEVELAND, OHIO.

MEANS FOR OPERATING CAR-DECK WINDOWS.

Application filed January 6,

To all whom it may. concern:

Be it known that we, WILLIAM J. Mc- GRATH and MARTIN H. SCI-IEFFT, citizens of the United States, residing at Cleveland, in the county of' Cuyahoga and State of Ohio, have invented certain new and useful lmprovements in Means for Operating Car- Deck Windows; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in means for operating car-deck windows to ventilate the car, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a sectional plan view of two adjoining windows adapted respectively to be opened outward according to the direction of travel, and showing the means for controlling' the same in corresponding positions in full lines and one of the windows and the controlling means in dotted lines. Fig. 2 is a like longitudinal sectional plan of two windows with the window at the right open and the other closed, and the controlling` means in corresponding relations. Fig. 3 is an elevation of the window controlling mechanism partly in section and considerably enlarged. Fig. 4 is a vertical sectional elevation of the parts shown in Fig. 3. Fig. 5 is a group view o'f details hereinafter more specifically described. Fig. 6 is an elevation partly in section of a modification of theinvention disclosed in the preceding views, being adapted in this instance to a single window. Fig. 7 is a cross section on line xfa, Fig. 6.

Respecting the two forms of the invention as thus shown, it is to be understood that they are both constructed upon the same principles, and that there is no difference between them excepting that in the first fivev views the invention is adapted to operate a set or pair of windows, both of which close upon the same post and are hinged at their opposite ends, while in Figs. 6 and 7, the invention is shown in connection with a single Window andis modified enough to adapt it to a single use. This modification will be also seen as existing only in a 'few small.' details. A

Now, having reference first to the invention in Figs. 1 to 5, inclusive, which is its double form, the invention is shown as com- Speccation of Letters Patent.

prising a bracket B adapted to be afhxed upon a post or supportP between the window openings and upon which the windows close, and which bracket has a bearing 2 in its forwardly projecting loot 3 at its bottom which constitutes the lower support for the hand operated rod R. Said bracket -further has a transverse rib at its front and top provided with a channel or groove 4, in which a tongue a upon the bracket arm A is adapted to engage, and a suitable screw 5 fixes the said arm upon said bracket.

In a sense the arm A is a part of bracket B, because it is made rigid therewith for supporting purposes, but both the manufacture and the use of the device call for the separation of' these two parts, and the said arm A is provided with a sleeve bearing portion 6 vertically, which serves as a support for the upper end of the said controlling rod R. About its lower portion the said sleeve 6 is provided with a series of serrations or teeth with rather long inclined sides, and these are engaged by corresponding serrations on the operating head H. Said serrations or teeth are indicated by 7, and head H further has opposite open slots 8 at its bottom engaged by a pin 9 on rod R extending into said slots. The said rod projects somewhat about sleeve 6 and has an arm 10 rigidly but removably secured upon the upper end thereof through which the windows are operated, as will be seen Jfurther along.

A spiral wire spring S is mounted upon rod R, and has its lower bearing upon the lower inward projection 3 of the bracket and its upper bearing against head H, so that said spring exerts a constant and uniform upward pressure and is adapted to keep said head in engagement with fixed sleeve 6. Hence, when operation occurs, and head H is rotated .by the rotation of rod R, it will be pressed downward a distance equal to the depth of said serrations or teeth 7 and permit the adjustment of the windows to be effected through arm 10, but will also hold the parts in whatever position of adjustment they may be left by such rotation. In this operation the said head H acts somewhat on the principle of a pawl with the teeth upon sleeve 6 as the ratchet member, but it has the advantage ol' permitting rotation of the rod R in either direction more or less the full distance of a complete adjustment and of automatically engaging and holding the parts wherever adjustment stops, whether the window be partially or wholly opened or closed, as the I case may be.

When the respective parts are in position as shown in full lines, Fig. l, both windows are closed and either can be opened from this point according to direction of rotation of rod R. Obviously, when one window is wide open, the other is closed.

From arm 10 the action is conveyed to windows W by means of a cross bar C pivoted at its middle upon the outer extremity of arm l() and having links L connected with its ends and with the screw postsl 14 fixed respectively in windows W, and with which posts the said links L are pivotally connected. This construction and arrangement permits a person who is standing in the car to reach up and grasp the handle of rod R and throw either window into any desired open position as well as to close either or both windows. Now, carrying this principle over to Figs. 6 and 7, the only material difference existing in the construction are the arms A and A2, which are laterally curved from bracket B, and instead of having a cross head or bar C the single link L is connected with the extremity of fixed arm l0. A collar 15 fixed upon rod R beneath the bearing 2 in both cases limits the upward movement ol rod R. Sleeve E incloses spring S.

What I claim is l. A device for controlling windows in the Y decks of cars comprising a supporting bracket having an arm provided with a series oi teeth, an operating rod through said arm and a member mounted thereon adapted to interlock with said teeth.

2. A device to open and close windows in the decks of cars comprising a supporting bracket and an arm rigid therewith having a circle of serrations at its bottom, an operating rod rotatable in said arm and a spring pressed member slidably mounted on said rod and engaged with said serrations, and means operatively connecting said rod with a window.

3. A car window controlling device comprising a supporting bracket and an arm detachably secured thereto having a tubular bearing with serrations at its bottom, and an operating rod through said bearing and a serrated tubular head slidably engaged on' said rod and a spring to hold said head normally in contact with said tubular bearing.

4. A car window controlling device comprising a support having a tubular bearing provided with serrations, in combination with an operating rod projecting through said bearing, a member having serrations engaging the serrations on said bearing and rotatably and slidably locked on said rod, a spring supporting said member in working position and an arm rigid with said rod and winldow operating means connected therewit i.

5. The supporting bracket and the arm removably aiiixed thereto having a tubular bearing with teeth at its bottom, in combination with an operating arm rotatably mounted on said bracket through said bearing, a serrated spring pressed head on said rod adapted to engage said tubular bearing, an arm rigid with the upper end of said rod, a cross bar pivoted at its middle on said arm and links pivotally engaged with the ends of said cross bar, and adapted to connect with dii'lerent windows.

In testimony whereof we sign this specilication in the presence of two witnesses.
