UNITED STATES PATENT OFFICE.
CHARLES A. BERG-MAN, OF LOS ANGELES, CALIFORNIA.
SASH-FASTENER.
To all whom it may concern:
e it known that I, CHARLES A. BERG- MAN, a citizen of the United States, residing at Los Angeles, California, have invented a new and useful Sash-Fastener, of which the following is a specification.
My invention relates to a new and novel sash fastener designed to be used for fastening sash in an open position. When in use the fastener holds the two sash in the same relative position and also prevents either sash being moved up or down in the frame. The device is detachable and is therefore convenient for travelers as well as for house holders. The means by which the beneficial results are obtained are fully shown in the accompanying drawings in which Figure 1 is a perspective view of my device complete and ready for use. Fig. 2 shows my device as it appears when actually in use. Fig. 3 is a top plan view of the cam plate used in my fastener and Fig. 4 is a transverse section taken on the line aa, in Fig. 8.
Throughout the several views like characters indicate like parts and referring to the details of construction, 1 is a spring wedge constructed of a metallic plat-e bent to a wedge shape and having one end formed into an outwardly bent plate 3 to which the cam plate 4 is attached by means of pivot 5.
6 is a thumb piece on the end of the cam plate having a perforation 7.
8 and 9 are the two sliding sash of an ordinary window.
The uses and relations of the various parts are most readily described by explaining the manner in which the fastener is used.
lVhen it is desired to fasten both sash of an ordinary double hung window in any position other than entirely closed, then my fastener is adapted to furnish adequate protection against any attempts to open the window from the outside. \Vhen it is desired so to fasten the sash of a window the fastener is placed with the spring wedge between the sides of the sash with the plate Specification of Letters Patent.
Application filed August 12, 1912.
Patented Sept. 2, 1913.
Serial No. 714,559.
3 resting upon the top of the inside sash. The shape of the wedge conforms to the bevel of the check rail which forms the top of the inside sash. In its normal position the spring wedge is slightly thinner than the space between the sash and does not offer any material resistance against the sash being moved. After the fastener is inserted the sash are placed in the positions desired, one or both partly or entirely open. By means of the thumb piece the cam plate is revolved on the pivot and by reason of its eccentricity its flanged edge comes into contact with the back edge of the spring plate and by continuing to turn the cam plate great pressure may be exerted upon said back edge, the result being similar to wedging the sash apart between the two window stops (not shown) and thereby ausing great friction between the sash and said window stops as well as between the sash. The binding eifcct from the friction is great enough to absolutely prevent the sash from being shifted without first releasing the cam plate or without destroying the sash or window frame and thereby creating a disturbance and attract ing the attention of those near at hand.
\Vhen not in use the fastener may be suspended by the side of a window by a cord passed through the perforation 7 in the thumb piece (3.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is In asash fastener, the combination of a cam plate adapted to exert pressure between the inner and outer sash of an ordinary window: a plate to which said cam plate is pivoted; and a spring wedge integrally formed on said plate to which said cam plate is pivoted, and having an upwardly projecting back edge upon which the edge of the cam plate contacts while wedging the sash apart, all as described.
