TRANsoM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 449,800, dated April '7, 1891. Application led November 17, 1890. Serial No,- 37l,647. (No model.)

To all whom, it may concern:

Be it known that I, OSCAR LUND, of Long Island City, in the county of Queens and State of New York, have invented a certain new and useful Improvement in Devices for Operating Skylights, &c., of which the following is a specification.

My invention relates to an improvement in devices for operating skylights, scuttles, hatches, and the like, in which provision is made for raising and lowering the skylight, scuttle, dsc., from a point below.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure vl represents av vertical section through the skylight or scuttle-frame from front to rear, showing the scuttle partially open. Fig. 2 is a view of the same in front elevation; and Fig. 3 is a bottom plan view, partly in section.

A represents the skylight or scuttle-frame, here represented as of rect-angular form, and is represented as provided around its upper edge with a rim a, over which the sash of the skylight or sides of the scuttle are intended to lap, as is usual.

B represents the skylightor top of the scuttle, and b the sash of the skylight or sides of the scuttle, the skylight or scuttle being shown as hinged at its back to the frame A at C. At or near its front or swinging side, opposite the hinge C, the said skylight or scuttle is provided with a depending curved bar D, fixed at its upper end to the skylight or scuttle, and sufliciently long to admit of the front of the skylight or scuttle being raised wide open without the lower end of the curved bar D passing above the frame A. Of course, if there should be no occasion for opening the skylight or scuttle to its full width, the curved bar D might be made proportionately shorter. The curve of the bar D is preferably upon the arc of a circle, so that its convex side will travel in proximity to the front of the frame A as the cover swings open. The front side of the curved bar D is provided with a groove d, extending longitudinally thereof and adapted to receive therein the cord or chain by which the device is operated.

On the inner side of the front of the frame A there is provided a guide and sheave-supporting block E, provided with a recess or groove e, adapted to receive the front of the curved bar D and prevent it from swinging laterally as it is moved up or down with the rise and fall of the skylight or scuttle. A pulley or sheave F is journaled in a recess f in the said block, with its face a short distance-from and opposite to the bottom of the groove d, in the face of the curved bar D. The said block E is further provided with a perforation e therethrough a short distance from the sheave F. The operating cord or chain G is secured at one end g, at or near the lower end of the curved bar D, and leads thence upwardly within the groove CZ in the face of the curved bar to and over the pulley or sheave F, thence downwardly to a point within convenient reach of the operator, and thence upwardly through the perforation e in the block E to the upper portion of the bar D or to the front of the skylight or scuttle,where its opposite endis secured-as, for example, at g.

Supposing the skylight or scuttle to be closed, it may be opened by pulling down upon thebranch of the operating cord or chain, the end of which is secured to the lower end of the bar D, and when opened as far as desired, may be fastened in position by securing both parts of the cord to a suitable cleat or catch. When it is desired to close it, if its own weight be not sufficient to cause it to fall, it may be positively closed by pulling downwardly upon the branch of the operating cord or chain secured to the upper part of the bar D or to the front of the skylight or scuttle, the other branch of the operating cord or chain rendering over the pulley or sheave F, and adjusting itself within the groove cl in the face of the bar D. Vhen closed', it may be locked in closed adjustment by fastening the two branches of the operating cord 0r chain, as before.
