WINDOW SUPPORT AND LOCK.
- SPECIFICATION forming part of Letters Patent No. 755,780, dated March 29, 1904.
Application filed. June 1,1903. Serial No. 159,515. (No model.)
To all whom it may concern:
Be it known that I, GERRYE. KNOWLTON, a citizen of the United States,residing at Boone, in the county of Boone and State of Iowa, have invented a new and useful Window Support and Lock, of which the following is a specification.
'My object is to provide an improved device to facilitate ventilation of a room and prevent burglary by retaining a lower sliding sash elevated and an upper sash lowered and the two sashes overlapped some distance and automatically locked together, so the lower sash cannot be raised or the upper sash pulled down to admit a person on the outside from enlarging an open space to gain entrance through the window.
My invention consists in producing a broad eccentric clamp and a narrow extension adapted to be pivotally connected with a bearer for engaging a window-sash advantageously, as hereinafter set forth,pointed out in my claims, and illustrated in the accompanying drawings,
' in which 2 5' Figure 1 isa diagrammatic view of a blank for making the bearer,and Fig. 2 is an end view of the bearer produced by bending the lateral extensions of the blank inward to project upward in parallel position. Fig. 3 shows the form of a blank adapted for making the clamp device. Fig. 4 is a side View, and Fig. 5 a perspective, of the clamp device ready to be pivoted to the bearer. Fig. 6 is a sectional view of the lower end of an upper sash and a top view of a lower sash and shows my complete device applied as required for practical use.
The numeral 10 designates the quadrangular main portion of the bearer,and 12 and 13 the parallel vertical upward projections provided with coinciding perforations.
The clamp consists of the enlarged end 1 1 and an extension 15. Both parts are bent into shape as shown in Figs. 1 and 5. The part 15 has V -shaped incisions, and the points cut loose are bent out and serve as means for fastening pieces of rubber 16 to the convex face of the eccentric as required to cushion it and, to allow the cushions to engage the face of a sash without bruising or marring it. By placing the rubber cushions on the projecting points and then subjecting them to pressure the points willpenetrate the rubber and be bent laterally to fasten therubber securely. The extension 15 of the clamp is doubled, as shown, and its end provided with perforations for receiving a rivet 17 by means of which the clamp is pivotally connected with the bearer to produce the complete device. It is obvious the parts thus formed of plate metal may vary in size and style of finish and that they can be made of wrought metal or cast in molds to accomplish the purposes contemplated. When applied to the top of a lower sash by means of screws extended through perforations in the flat part 10 of the bearer, as shown in Fig. 6, the eccentric part of the clamp having rubber cushions on its face will normally rest against the face of the upper sash, as shown in Fig. 6, and lock the two sashes together when in a closed position. Placing the pivoted part in position, as indicated by dotted lines in Fig. 6, allows free movement to both sashes. Raising the lower sash some distance and then replacing the clamp against the upper sash locks the two sashes together when partly overlapping each other, so they can be jointly moved downward and an open space left at the top and alsoat the bottom for the admission offresh air. Or the bottom sash may remain down to its limit and the upper sash lowered, and vice'versa, and at all times when one or both of the sashes are moved from their normal closed positions to produce openings, and such openings can be too small to admit any person to pass therethrough, and consequently ventilation can be safely eifected by opening spaces at the bottom and top of a window without incurring dangers incident fromportion wide and curved and having pointed having a pluralty of V-shaped incisions and a narrow extension 15 as shown and described I for the purposes stated.
GERRY E. KNOWVLTON.
