Description

' UNITED STATES PATENT OFFICE.
JOSEPH E. TOFT, OF EXIRA, IOWA.
sAsH-HOLDER.
SPECIFICATION forming part of Letters Patent No. 350,511, dated October` 12, 1886.
Application filed March 24, 1886. Serial No. 196,408. (Model.)
To all whom t may concern:
Beit known that I. JOSEPH E. TOFT, a citizen ofthe United States, residing at Exira. in the county of Audubon and State of Iowa, have invented a new and useful Combined Sash- Holder and Safety-Lock, of which the fol1owing is a specification.
My invention consists of a combined sashholder and safety lock; and the objects of my invention are, first, to provide facilities for the balancing and locking of upper and lower sashes of windows in any desired position independently of each other; second. to obviate the wear and indentation ofwindow sash and casings; third,to provide facilities for ease and convenience in the manipulation of sashes. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of jambras ing of window-frame after removal of sash, showing the position of sash-holder as applied to window-frame. Fig. 2 is a vertical section ofjambcasing, showing operation'of shaft A, cam C, and metallic plate D.
Similarletters refer to similar parts through out the several views.
The shaft A, crank B, 4cam C, metallic plate D, and spring F constitute the working parts of the invention. Crank lB turns shaft A, forcing cam C against metallic plate D, which comes in contact with window-sash, holding same at any desired position. Spring F, compressed by downward pressure of crank B, returns to position over upper side of crank B and holds same in position until release, as shown in Fig. l. The cam C on shaft A is adjustable, and can be applied to upper or lower sash.` Shaft A passes through inside window casing and jamb, as shown in Figs. l and 2and is kept in place by esontcheon, that portion of vshaft passing through i escutcheou being reduced in size. Cam C Works on shaft A in an aperture cut in the sash-slide of Window-frame,vas\ shown in Fig. v2. Plate D is a flexible metallic plate covering the aperture in which cam C works, the upper part of plate D being slightly curved and sunk. into jambcasing` to which it is secured at upper end by wood-screw. l
I am aware that prior to .my invention there have been patented and constructedvarious apparatuses for balancing and locking windowsash. I therefore do not claim such a combination, broadly; but
What I do claim as my invention, and desire to secure by Letters Patent, .is-
In a sash holder and lock, the combination of the crank B and escutcheon E with the shaft A. cam C, adjustable on shaft A, metallic friction-plate D, and springcatch F, all` as substantially set forth and described.
JOSEPH E. TOFT. Vitnesses:
