JOHN H. SHA\V, OF NE? HAVEN, CONNECTICUT, ASSIGNOR TO SARGENT &
CO., OF SAME PLACE.
TRANSOM-LIFTER.
SPECIFICATION forming part of Letters Patent No. 328,722, dated October 20, 1885. Application filed September 14, 1885. Serial No. 177,002. (No model To all whom it may concern.-
Be it known that 1, JOHN H. SHAW, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improve- 5 ment in Transom-Lifters; and I do hereby declare the following, when taken in connection with accompanying drawing, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1,21 side view of the device as applied to a transom; Fig. 2, a front view of the same; Fig. 3, a vertical section through the bracket,
1 enlarged.
This invention relates to an improvement in that class of devices for opening and closing transoms in which a vertical rod arranged upon the jainb of the door and parallel with the door is connected to the transom, so that by a vertical movement of the rod in one direction the transom is opened and in the opposite direction is closed, the object of the invention being a simple device by which the adjusting movement of the rod may be mechanically made, and so that the transom will be securely held at any point to which it may be adjusted through the same mechanism by which the rod is raised or lowered; and the 0 invention consists in the construction as hereinafter described, and particularly recited in the claim.
A represents the jamb of the door,- B, the transom, as here represented, hinged to the 5 lintel. C is a vertical rod, its upper end supported in a slide, D, arranged on a vertical guide, E. To the transom an arm, F, is attached, extending outward, and between the slide D and the arm F is a link-connection, G,
so that as the slide is moved upward the transom will be raised, or drawn downward the transom will be closed in the usual manner. The rod C extends downward and passes through a U shaped bracket, H. This bracket 5 is secured to the jamb, the bend of the U outward. In one leg of the bracket an internallyscrew-threaded nut, I, is arranged, free for rotation, but supported against movement in an axial direction, and the portion J of the rod adapted to pass through said nut is correspondingly screw-threaded. The nut carries upon its face a bevel-pinion, K, upon the under side of the leg, the said pinion forming a flange on the nut to rest upon that side of the leg, and so as to support the nut against downward movement. In the bracket, at right angles to the rod C,'is a shaft, L, extending through to the inside of the bracket, and there provided with a bevel-pinion, M, corresponding to the pinion K, and so as to work therein, 6 as indicated in Fig. 1. Upon the outer end of the shaft a crank, N, or other suitable handle is fixed, by which the shaft and the pinion M may be conveniently rotated, the rotation of the shaft imparting corresponding rotation to the nut I.
The parts being properly applied, as illustrated, and the transom closed, if it be desired to open the transom, the crank is turned to impart rotation to the nut in the direction which will, because of the stationary character of the nut in the bracket, cause the rod to rise, and when the desired extent of opening is attained the crank is left, and the rod and the transom remain in that position, as the weight of the transom has no tendency to rotate the nut to permit the rod to descend. To close the transom, turn the crank in the opposite direction. The nut revolving accordingly will permit the rod to descend. Then the transom s may be closed or opened to any desirable extent, and wherever it may be set it will be securely held without other fastening device than that imparted by the mechanism through which the transom is raised.
In order that the nut may force the transom toward its closed position and hold it in that closed position, the nut should be interlocked with the bracket to prevent its rising from its seat. This may be done by a collar, P, ap- 9O plied to the body of the nut below the leg of the bracket into which it is set; but ordinarily the pinion M will be sufficient to prevent such movement.
I claim 9 5 The herein-described improvement in transom-lifters,consistingin the combination of the lifting-rod C, arranged to work upon a vertical guide,and with connections, substantially such as described, from the rod to the transom, a
to said rod, carrying a pinion at one end, corresponding to the pinion on the bracket, and
a handle at the outer end, by which the said pinion may be rotated, substantially as described.
