FRANCIS V. PHILLIPS, OF CHICAGO, ILLINOIS, ASSIGNCR TO GEORGE H. DAYTON, OF SAME PLACE.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 243,079, dated June 21, 1881.

' Application filed April 5, 1880. (No model.)

To all whom it may concern Be it known that I, FRANeIs V. PnILLIPs, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Transoms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to devices for opening, closing, and locking transom-windows; and it consists in the several features of construction in the transom-fixtures for this purpose hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 shows my improved fixtures as seen in a front elevation of the transom. Fig. 2 is a side elevation of the fixtures in place; and Figs. 3, 4, 5, 6, and 7 are detail views.

A represents a transom-sash, centrally pivotegl to the frame B by the external pivot-plate, C

D is a lever or arm formed upon one of the center plates, 0, or otherwise rigidly secured therewith to the sash A.

R is avertical rod extending down ward from the extremity of the arm D to a point within easy reach from the floor.

E is an eye applied to the door-frame as an upper guide to the rod It, having an oblong aperture, as better shown in Fig. 3, to permit the rod to move outward and inward as its end follows the are described by its point of con.- nection with the arm D.

F is a lower plate, having an arch or eye, G, through which the rod passes. In connection with this plate and eye are arranged the looking devices for the rod. Said locking devices consist of notches a, cut at suitable intervals in the rod R, a projection, p, on the plate F, adapted to enter said notches, a friction bearing-block, L, working inwardly and outwardly within the arch or eye G, and a spring, .9, or other suitable means for compressing the block Lupon the rod R, to hold the same fixedly from vertical movement. The arch or eye G is, of course, transverse to the plate F, and is formed with lateral grooves, g, in its sides, whereby the bearing-block L is held in place while permitted to move, as described. A suitable handle, h, being formed on the bottom of the'rod, the transom may be operated by one hand only by pulling the rod outward against the force of the spring 8 to disengage the notches n from the projection 19, and then sliding the rod up or down, as may be desired. When the rod is released the spring throws it inward, and theprojeetion p enters the nearest notch, fixedly holding said rod from further vertical movement.

The lever D is cast integral with the external pivot-plate, C, or rigidly secured thereto, or to the sash therewith, by the same screws that hold the center plate. The lever thus secured to the center plate projects downward at an angle of about forty-five degrees, so that the extremities of its are of movement in swinging the transom-sash from a vertical to a horizontal position will be equally distant from the frame. The end of the lever or arm D has a keyhole-shaped slot, (1, and the rod R is turned at the end to have the form shown in Fig. 6. The terminal section, a, is reduced in size to enter the slot of the arm, and is turned in such direction that it may be thrust through the slot only when the rod is thrown out at the bottom, the sash being in place. When, thereafter, the rod is secured to the frame by the eyes E F the rod cannot disengage from the arm. By reason of the key-hole form of the slot (Z, the horizontal bearing-section b of the rod will work only in the eye 0 of the said slot.

The united functions of the pressure-block L and spring 8 will be discharged by a spring arranged to bear upon the rod directly, and such a spring so applied is intended to be regarded as the equivalent of the coil-spring s and block L hereinabove described.

When the pivots of the transom-lights are external to the sash, as herein shown, the sash will naturally fall open by its own weight, and the rod R will act only to restrain its fall or to pull it shut. The strain upon the rod may therefore be only that of tension, wherefore it may be very light and inexpensive.

Having thus described my invention, I claim 1. In combination with the rod R, having the notches n, and the plate F, having the projec- I whose axis is in the plane of one of the surtion 1), the eye G and the bearing-block L actuated by a spring, 3, to press the rod inward to engage the projection 19, substantially as and for the purposes set forth.

2. The lever D ofatransom-fixture, cast solid or otherwise rigidly secured to the center plate, 0, having the external pivot, as shown, in combination with the rod R, substantially as described.

3. The lever or arm D of the fixture described, and a transom-sash hung on a pivot l faces of said sash said arm being inclined downward, as shown, in combination with the rod R, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

FRANCIS V. PHILLIPS.
