second, in the spring pawl engaging with notches in the bar, whereby the said bar is secured in positionwhen the skylight has been raised to the desired point; third, in a rollerguide for the operating-rope.

In the drawings-forming part of thisspecification, Figure 1 is an elevation of theflimproved lifteras attached to the skylight. Fig. 2 is a perspective view showing the same in detail. Fig. 3 is a front elevation ofa portion of the same, showing the spring-pawl locking device.

In the drawings, A is the skylight, and B the casing to which it is hinged. Tothe casing Bis secured a bracket, 0, provided with lugs 00. The sleeve or guide D is attached to the bracket 0 by the pin c, which passes through holes in the lugs c act the bracket 0. The guide D can therefore rotate around the pin 0, to allow of the changes in direction of the bar E due to the rise and fall of the skylight. The guide D consists of a fiat frame or back, d, provided with a short sleeve, d, at its upper extremity and asimilarsleeve, d, at its lower extremity, through both'of which passes the barE. It also has a pulley, 1, adapted tovcarry arope, R, and 'incl osed in a suitable box,p. The lug L is pierced to re ceive the end of the rope R.
