ALBERT LANGSTROM, OF COUNCIL BLUFFS, IOWVA, ASSIGNOR OF ONE-HALF TO A. B. WVALKER, OF SAME PLACE.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 377,312, dated January 31, 1888.

Application filed June 15, 1887. Serial No. 241,407. (No model.)

To all whom it may concern:

Be it known that I, ALBERT LANGSTROM, a citizen of the United States, residing in Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Transom-Lifters, of which the following is a specification.

The object of this invention is to provide means for conveniently operatingi. 6., opening and closinga transom-window and looking it in an open, partially open, or closed po sition.

To this end it consists in the mechanical arrangement hereinafter fully described, and illustrated in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a side elevation showing the transom-window closed and locked. Fig. 2 is a perspective view showing a modification of the device shown in Fig. 1, and Figs. 3 and 4 are views in detail. v

In the drawings, 1 represents the frame of the door to which the transom-window 2 is hinged. Attached to one of the stiles of the transom-window is a metal bracket, 6, which is bent outward at its free end and terminates in a coarse screw, 5. The upper end of the transom-lifting rod 3 has an eye, 4., which is adapted to screw on such lateral threaded projection of the bracket 6. This means of connection enables the two parts (3 and 6) to be very easily and quickly attached and detached. The lower end of the rod 3 is provided with a finger-piece, 10, as shown in the drawings. This rod 3, which is slightly bent to give it a spring, is supported and adapted to slide in brackets 11 and 12, that are attached by screws or otherwise to the jamb of the doorframe. The lower one of these brackets, 12, has a hole, through which the rod 3 slides, made somewhat larger than the rod and straight across the side next the window-frame to form a tongue, 13, which engages with one of a series of transverse slots, 14, cut in the under side of the rod, and serves to lock the rod and thereby the transom-window at any position in which it may be placed.

It will be understood that the notches 14 in the lifting-rod are to be arranged so that the lifter will automatically lock itself when lowered, and thus prevent the window being opened from the outside.

To insure the transom-window being securely held, the liftingrod 3 should have sufficient spring to force any of the notches 14 upon the tongue 13 on the lower bracket when one is brought opposite the same. The rod 3 is provided with additional security by means of a locking-finger, a, pivoted to the lower bracket, 12. This finger a, when one of the notches in the rod 3 is in engagement with the tongue on the lower bracket, hooks over the said rod, and thus locks it in that position.

The perforation in the lower bracket being 6 enlarged, allows the necessary play of the rod for disengagement with the tongue 13 when the transom-window is to be opened or closed. The upper end of the lifting-rod should be bent outwardly a little to obviate severe bind- 7o ing in the upper bracket, and thus prevent the lifting-rod being worn or marred.

The foregoing arrangement is equally well adapted for light transom-windows hung as shown in the drawings or heavy transom-win- 7 dows hung in the center.

For heavy transom-windows hung from the upper edge, I modify the device shown in Fig.

1 of the drawings by the addition of an arm, 15. This arm 15 is connected at its lower end by a wire loop-hinge, 16, to the rod 3, the upper end being connected with the transomwindow, as shown by the drawingsi. e., like the connection therewith of the upper end of the lifting-rod when arranged for light transom-windows, as shown in Fig. 1.

\Vhen the lifting-rod 3 is arranged for heavy transom -windows, its upper end is passed through a bracket, 17, Fig. 2, designed to hold the rod straight, and thus through the arm 15 facilitate the adjustment of the transom-window.

From the foregoing it will be seen that I have provided a simple and easy means for operating transom-windows in houses, cars, 5 or other places where they are located beyond the reach of the hands, and the construction ward, as specified, and a series of fixed brackbeing such thata child can Work it with the ets, with one of which the spring of said rod 10 ease of agrown person. causes it to engage, as shown and described.

Having thus described my invention whatI 5 claim as new, and desire to secure by Letters ALBERT LANGSTROM' Patent, is Witnesses:

The combination, with a transom-Window, A. B. WALKER,

of a lifting-rod having notches and bent out- H. G. CORY,
