CLYDE C. HALL, OF BELLAIRE, OHIO. I

TRANSOM-LIFTER.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed May 3, 1907. Serial No. 371,600.

T all whom it "may concern:

Be it hiown that I, CLYDE C. HALL, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented new and useful Improvements in T ransom-Lifters, of which the following is a specification.

This invention relates todevices for lifting or operating transoms, and it has for its object to provide a device of simple and inexpensive construction which may be readily applied in position for operation, and by means of which a transom may be lifted to a horizontal position and supported in such position.

Further objects of the invention are to simplify and improve the construction and operation of this class of devices.

\Vith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fullydescribed and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings, Figure 1 is a perspective view showing the improved transom lifter applied in position for operation to the transom over a door, the housing or casing being removed. Fig. 2 is a side elevation showing the device with the housing in position. Fig. 3 is a front view showing the device with the housing in position. Fig. 4 is a front view showing the device on an enlarged scale, the housing having been removed. Fig. 5 is a side view showing the device with the hous.

ing removed.

Corresponding parts in the several figures are denoted by like characters of reference.

1 designates a suitably bifurcated brac 'et or hanger having a screw threaded shank 2 whereby it may be conveniently mounted in. position for operation upon a door jamb 3 or in some other suitable position. The hanger or bracket 1 constitutes a bearing for a shaft 4 carryin a sprocket pulley 5 and having a crank arm 6 which latter may be of any suitable length and is provided with a wrist pin 7 that is connected by means of a link 8 with a bearing 9 upon the transom that is to be operated and which is shown at 10. Another sprocket pulley 11 is supported for rotation upon a suitable supporting member such as a screw 12 which may be driven in the door jamb 3 in a position where it may be conveniently reached by the operator.

he sprocket pulley 11 has a crank arm 13 whereby it may be conveniently manipulated, and said pulley is connected with the sprocket pulley 5 by means of a flexible member A preferably comprising short chain sections 14 which are connected with each other by cords or wires 15; this construction being resorted to not only on account of inexpensiveness but also in order to permit the flexibl'e member A to be partly twisted, as is necessary for the reason that the sprocket pulleys 5 and 11 are disposed in place at right angles to each other.

A casing or housing is provided, said housing being preferably composed of two parts or sections 16 and 17 containing respectively the pulleys 5 and 11, andv the casing member 17 being provided with a slot 18 through which the handle 13 projects.

For the purpose of retaining the parts in any of the various positions to which they may be adjusted, there is provided a friction brake B comprising a spring coil 19 engaging the screw or supporting member 12 of the sprocket pulley 11 and having arms 20 and 21, the former of which is secured upon the 1 door jamb 3 by means of a staple 22 while the arm 21 is formed with a bent portion constituting a shoe 23 and with a terminal prong 24 which projects through an aperture 25 in the casing or housing. bent portion or shoe 23 of the brake member presses a portion of the flexible connecting member A into engagement with the adj acent wall of the housing, holding the same with sufficient force to maintain the parts in N adjusted position. By pressure against the projecting prong 24 the pressure of the shoe 23 against the flexible member will be re vlaXed, and the parts may be freely adjusted.

The parts or sections 16 and 17 of the housing or casing are designed to overlap, and one of said sections may be provided with slots 26 for the passage of connecting screws 27.

Normally the c From the foregoing description taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. By

turning the sprocket pulley 11 by means of the crank handle 13, motion will be transmitted to the pulley 5 having the crank arm 6 which is connected with the transom, thus efl'ecting adjustment of the latter. The parts may be retained in the position to which they are adjusted by the friction shoe 23 engaging the flexible connecting member A and holding it in engagement with the wall of the housingor casing; by pressure upon the prong or finger piece 24:, the friction member may be disengaged from the flexible connecting member, and the parts may be readjusted as may be desired.

Having thus fully described the invention, What I claim as new is In a device of the class described, a pair of sprocket pulleys, a transom, means for connecting the latter with one of the pulleys,

two pulleys, a casing or housing for the,

pulleys and the flexible element, a spring member coiled and supported adjacent to the rear side of one of the pulleys and having arms extending therefrom, means for securmg one of said arms in a fixed position, a shoe formed u on the other arm, said shoe engaging the exible element and forcing it into engagement with the wall of the housing, and a terminal finger upon the shoe carrying arm extending through an aperture in the housing.

In testimony whereof, I aflix my signature in presence of tWo Witnesses.
