GEORGIEv A. LINCOLN, OF EAST SOMERVILLE, MASSACHUSETTS.
IMPROVEMENT IN SASH OPENING AND CLOSING MECHANISMS.
Specication forming part of Letters Patent No. 158,850, dated January 19, 1875; application filed December 19,1874.
To all 'whom it may concern Be it known that I, GEORGE A. LINcoLN, of East Somerville, of the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Mechanism for Opening land Closing WindoW-Sashes and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of Which- Figure l is a frontvelevation, and Fig. 2 a side elevation, of a door-frame and Ventilatingsash With my invention appliedthereto. Fig. is a vertical section of such taken through the spring-bolt.
My invention mainly consists in the combination of an arm and series of guide-Wheels to be projected from a door-frame, with a bolt and its case provided with another arm and guide-wheel, and to be applied to a sash, all being to operate with two cords, as and for the purposes as hereinafter set forth.
In such drawings, A denotes the door-frame and B the sash, which at bottom is connected with the frame A by hinges a, a, in order for the sash to be turned from a vertical down into an inclined position, chains o b being' iixed to the sash and frame, in order to determine the extent of depression of the sash. A springbolt, C,attached to the upper rail of the sash, has a catch, D, over it and applied to the doorframe. The said catch forms part of a bracket or arm, E, that extends from the door-frame in manner as shown, and supports a series of grooved Wheels, c, d, e, f, and g, arranged in it as represented. Furthermore, there is extended from the bolt-caseF an arm, Gr, also two ears, h lathe latter serving to support the axle of another grooved Wheel, t, arranged between them. From a knob, 7c, extending from the spring-bolt a cord, l, projects down to and partly around the Wheel i; thence to and partly around the Wheel d, thence to and partly around the Wheel e, thence to and partly around one of a pair of grooved Wheels, m n, arranged as shown, and having their frame o xed t0 the upper part of the door-frame. Another cord, p, fastened to thearm G, extends to and partly around the Wheel g, thence to and partly around the Wheele, thence to and partly aroundthe Wheel f, and thence to and partly around the other of the pair mn of Wheels, both cords being led down to and Wound around a belaying cleat or hook, r, projecting from the door-frame.
By pulling down the first cord l, We shall not only move the bolt downward out of engagement With its catch, but open the sash or draw it outward.
The other cord, p, is to effect the raising and closing of the sash, which cannot be accomplished by the cord Z.
With my mechanism applied to a door and its sash, the latter may be unlocked and opened to any desirable extent for ventilation, and afterward be readily closed and locked.
I claiml. The combination of the arm E, its guide- Wheels c, d, e, f, and g, and bolt-catch with the bolt C, and its case F, provided With the arm G and guide-Wheel 1S, all being substantially' as described, and to operate With cords, as and for the purpose set forth.
2. The combination and arrangement of the pair of guide-Wheels m n, applied to the doorframe, With the arm E and its guide-Wheels, and With the bolt and case provided with the Wheel and arm, and applied to the sash, all being arranged as speciiied.
