TRANSOM-LIFTER.

SPECIFICATION forming part of Reissued Letter; Patent No. 10,264, dated. December 26, 1882.-

Original No. 148.538, dated March-10, 1874.

of Chicago, in the county of (look and State of Illinois, have invented certain new and use ful Improvements in Transom-Lifters; and I do hereby declare the following to be a full and exact description of thesame, reference being bad to the accompanyingdrawings, forming part of this specification, in which- Figure l is a side elevation, and Figs. 2 and 3 views of partsin detail.

Similar letters of reference in the accompanying drawings denote the same parts.

This invention is an improvement upon my patent dated March 11, 1873, No. 136,801, in which provision was made against the bending of the long nprightrod or handle of the transom-lifter by the weight of the sash atsthe point where it was jointed to the lifting-arm connected to the side or edge of the sash, this being accomplishedby prolonging the upright rod above the point of junction of the liftingarm and providing said upright rod with a friction-roller at the point ofjunction, saidroller bearing against the wall and helping to sustain the weight of the sash.

The object of the present invention is to provide means for supporting the upright rod against the bending pressure of the sash when the latter is hinged at its bottom, and at the same time prevent the breakage of glass in the transom in case the latter is allowed to fall suddenly.

ltalso has for its object to provide improved means for connecting the lifting-arm to the transom.

To these ends the invention consists, first, in jointing the lifting-arm to its operating rod or handle at the upper end of the latter, and

in providing the operating rod or handle with I a socket at or near its junction with the lifting-arm, said socket sliding on a stationary upright rod attached to the wall; secondly, in inter-posing a spiral spring onthe stationary rod between the sliding socket and the upper guide-bracketot'theoperating-rod in such manner as to sustain the weight of the sash when it is lowered, and prevent any sharp concussion when the transom falls suddenly; and, finally, in a hayonet-joint connecting the lifting-arm to the bracket on the transom, said Application for reissue filed May 31', 1882.

thebracket and a corresponding slot in the socket on the arm, the parts being so arranged that they cannot be disconnected in any part] of the are described by the transom when the lifting-arm is attached to the operating-rod, all of which I'will now proceed to describe.

In the drawings, T is the transom-sash, pivoted or hinged in the present instance at its lower edge; L, the lifting-arm, that connects the sash to the upright rod; U, the upright rod, passing through two guides, G G, both of which are located below thejuuction ot' the rods L U, the guide Gr being provided with a set-screw, 8, arranged to hold the rod U at any point desired. The upright rod U, instead of being prolonged at its upper end above its junction with the lifting-arm, as in my former pateut,-terininates atthat point, and is provided at the front with ears e, to which the lifting-rod is pivoted, and at the rear with a socket, S, which incloses and slides upon a stationary upright rod or long guide, U. The latter is supported at its lower end below the socket S by the bracket com posing the guide G of the'rod U and at its upper end by a bracket, B. g

I represents aspiral spring,inclosing the rod U between the socket S and the guide G.-

B is a reversible bracket on the transomsash, adapted to be inserted from either side of the socket on theliftingarm L. It will be seen that the weight of the sash is supported equally by the rods U U and their brackets, and cannot bend either. hen the sash is lowered until the socket S comes in contact with the upper end of the spring I its weight is sustained by the latter vertically. Consequently when the sash is allowed through carelessness to fall suddenly the spring relieves the shock which would otherwise occur,

and prevents damage to the glass. The lift- -making it doubly secure against accident.

' Having thus described myinvention, what I claim as new is 1. The stationary upright rod U, supported by brackets G, B, and provided with a spiral spring I, in combination wit-h the movable upright rod U, having the socket S, arranged at or near thejunction ofthe rod U, and liftingarm L, substantially as described, for the purpose specified.

2. The lifting-arm L, having the socket j and slotj,in combination with the transverse bracket B, having the pin or bearing 70 and ron ue k arran ed and o eratin substantially as and for the purpose specified.

3. The combination, with a transom-window, of the bracket B, lifting-arm L, long guide U, and lifting-rod U, having sliding connection with guide-rod U, all substantially as described, and for the purposes set forth.

4. The combiuatiou,with a transom-window and its vertical lifting-rod, of a long stationary guideaud support for the upper end of the vertical lifting-rod, by which the latter is held to a rectilineal path through suitable connections, substantially as described, and for the purposes setforth.

5.The combination, with a transom-window, of the separate guide U, socket S, and vertical lifting-rod, substantially as described, and for the purposes set forth.

6. The combination, with a transom-window, of the guide U, guide-socket S, vertical lifting-rod U, and connecting rod or arm L, and suitable transom-coiinections, all substantially as described, and for the purposes set forth.

7. The combination, with the liftingrod and the means by which itis connected to the transom, ofa spring to'receive the shock ofthe window in falling or swinging, suddenly, substantially as described, and for 'the purposes set forth. i

8. The stationary upright rod or guide U, supported on the casing and provided with a s iral spring, I, in combination with the movable upright rod U, having the socket S, ar-

ranged at or near the junction of said rod with the lifting-arm L, and suitable transom-connections, all substantially as described, and for the purposes set forth.

9. The combination, with atransom lifting rod and lifting-arm, of a reversible bracket, B, for connecting the transom with the liftingarm, substantially as described, and for the purposes set forth.
