IMPROVEMENT IN SKYLIGHT-LIFTERS.
Specification forming part of-Letters Patent No. 173,221, dated February 8, 1876; applicationfiled July 30,1873. 1
elevator, and its necessary fixtures, bolts, pulleys, springs,&c., the object being'to elevate any skylight upon itshinges, and securely fasten it when closed, or at any given elevation. I
Figure l is aside elevation of the elevator and its adjustments, as follows: 1, side or holding plate; 2, skylight-plate; 3, elevatorrod; 4, barrel; 5, bolt; 6, trigger; 7, triggerspring; 8. elevator-pulley; 9, barrel-pulley; 10, stop-bolt. Fig. 2 is a front view of the elevating device. r
A rivet at a secures the barrel of the elevator to the holding-plate 1, which is secured to the side of the well-hole, opposite the hinged side of the skylight.
A rivet at b secures the top of the elevator 3 to the skylight-plate 2, which is screwed to the under part of the skylight A.
A rivet at c secures the trigger 6 to the projection at the front of the barrel 4.
A stout cord, called the pulley-cord, is now passed through the opening at-d, Fig. 2, and secured by a knot at the end. It is next passed around the pulley at the foot of the elevator-rod 8 and over thebarrel-pulley 9.
A similar co'rd, called the trigger-cord, is next passed through the opening in the end of the trigger and secured by a knot.
Now, by pulling the trigger-cord the bolt 5 I is withdrawn, and by pulling the pulley-cord the elevator may be raised 'or lowered to any desired position.-
The elevator-rod 3 is a metallic tube, hinged v to the skylight-plate at I), having a mortise at its foot, in which is insertedand held the pol ley 8 and having certain perforations along its entire length for the reception of the bolt 5.
The barrel 4 is also a metallic tube, hinged to the side or holding plate at a, having two parallel projections on the one side, between which the pulley 9 is adjusted, a projection in front, on which the bolt5is secured above by the stop-bolt 10 and the trigger 6 below by the rivet c, and a thirdprojection at the opposite side, in which the pulley-cord is secured at d, Fig. 2.
The bolt 5 is laid upon the projection at the low the same in its ascent, combined with the sheave-wheels 8 and 9, and an operating cord, substantially as specified. I
2. The bolt 5 and trigger .6, in combination with the notched lifting-rod 3, barrel 4, and
sheave-wheels 8 and 9, substantially as speci- Witnesses:
