AUTOMATIC WINDOW-SASI-I-FASTENING DEVICE.

Specification of Letters Patent.

Patented Sept. 17, 1907..

Application filed January 2, 1907. Serial No. 350,413.

To all whom 'it may concern:

Be it known that I, CHARLES H. BELLAMY, a British subject, and a resident of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and useful Improvements in Automatic Window-Sash-Fastening Devices, of which the following is a full, clear, and exact description.

Tliisimprovement relates to sash fastening or locking devices which are attached to and rest upon the meeting rail of the lower sash.

The object of the invention is to provide a sash lock orfastener, simple in construction, automatic in operation, and which can be easily applied by unskilled persons, without detriment to the window, windowsash or casing, this fastener being designed to lock the sashes in any desired position through frictional vengagement, admitting at all times of the closing of the upper or the lower sash, or both, but effectually preventing the enlargement of the opening of either or both, unless the fastener be released. These and other objects, as well as the underlying structural features, will become more apparent from the following specification and the appended drawings, and also by reference to the appended claims.

In the drawings: Figure lis a perspective view of the improved sash fastener applied to the upper face of the meeting rail of the lower sash of a window; Fig. 2 is a longitudinal section on the line 2 2, Fig. l, the locking wedge being shown as raised out of operative relation to the face of the upper sash; Fig. 3 is a perspective view ofthe wedge block g Fig. 4 is a perspective view of the casing and the integrally-attached supporting plate; and Fig. 5 is a detail of the operating pin and its retaining devices.

Referring now to these drawings, C indicates a casing constructed and arranged to be secured to the meeting l rail of the lower sash, for this purpose being formed integral with the basal plate or flange B, which is designed to be fastened fiat upon the underlying sash by means of the screws S. Said casing C consists of a steel plate A extending upward from the basal flange B over and away from the face of the upper sash and provided with two cheeks or iianges C1 and C2 formed on the margins of its rear face. The steel plate A, which constitutes the rear wall of the casing, lis longitudinally slotted, as at E, the upper end F of this slot being enlarged as shown.

W is the automatic locking member, in the nature of a wedge block slidably mounted on the rear wall of the casing and between the iianges Cl and C2. The face of this block which coperates with the inner face of the upper sash may be provided with a frictional facing G, or such face may be otherwise adapted to afford a firm grip upon the sash. Extending from front to back of the block W is an aperture K, which may communicate at its front end with a depression L in the face of the block. Within this aperture is rotatively fitted the operating pin P, this pin extending rearward from the block through the slot E and being suitably provided with a handle portion R. The portion of this pin which is received within the slotis of greater width than thickness, so that, when the pin stands as shown in Fig. l it may be received within the body of the slot, whereas, when it is turned as illustrated in Fig. 2, it may only be received within the enlarged portion of the slot. Cotter pins X may serve to retain the pin in the block, one of these pins passing transversely. through the extremity of the pin P and being housed within the depression L, while the other may pass through the operating pin outside of the rear wall of the casing.

The operation of the sash fastener is entirely automatic. When it is screwed in place upon the meeting rail of the lower sash, the operating pin P is so turned that its narrowest dimension is normal to the length of the slot E, within the body of which the pin freely slides in this position. Thus the wedge member is free to slide between the two fianges or cheeks C1 and Cl of the casing C, until the forward surface of said wedge comes into frictional engagement with the upper sash. It will be readily seen that any attempt now to lower the upper, or to raise the lower, sash increases the resistance and eifectually locks both sashes. When, however, the wedge member is raised by the operating and connecting pin P and the latter is turned, so that it lies transversely of the slot E within the enlarged portion F thereof, the wedge member is held out of frictional engagement with the upper sash and the sashes may be l raised orlowered at will.

What is claimed as new is:

l, In an automatic sash fastener, the combination of a casing constructed and arrangedto be secured to the meeting rail of a lower sash and to incline therefrom over and away from the face of the other sash, and a wedge block mounted slidably in said casing for engagement with the face of said other sash.

2. In an automatic sash fastener, the combination of a retaining plate constructed and arranged to be secured to the meeting rail ot' a lower sash and to incline therefrom over and away from the race of the other sash, and a slidable locking lnember mounted on said plate and arranged to engage with the face of said other sash.

3. In an automatic sash fastener, the combination of a retaining plate constructed and arranged to he secured to the meeting rail oi a lower -sash and to incline there* from over and away from the face of the other sash and having longitudinal marginal retaining iianges formed on its inner face, and a slidable locking wedge block mounted on said plate and between said flanges.

4. In an automatic sash fastener, the combination of a casing constructed and arranged to be secured to the meeting rail of a lower sash and having a rear wall disposed to incline therefrom over and away from the face of the other sash, an automatic locking member longitudi-` nally movable on said wall for cooperation with the face of said other sash, and means for preventing separation of the easing and locking member.

5. In an automatic sash fastener, the combination of a casing constructed and arranged to be secured to the meeting rail of a lower sash and having a rear wall disposed to incline therefrom over and away from the face of the other sash, an automatic locking member longitudinally movable on said wall for coperation with the face of said other sash, and means for operating said locking member. Y

G. In an automatic sash fastener, the combination of a casing,r constructed and arranged to be secured to the meeting rail of a lower sash and having its rear wall disposed to incline therefrom over and away from the face of the other sash, an automatic locking member longitudinally movable on said wall for coperation with the face of said other sash, and means for maintaining said locking member out of engaging relation with reference to said sash-face.

7. In an automatic sash fastener, the combination of a casing constructed and arranged to be secured to the meeting rail of a lower sash and having its rear wall disposed to incline therefrom over and away from the face of the other sash, an automatic locking member `longitudinally movable on said wall for cooperation with the face of said other sash, and single means for elfecting longitu dinal movement of said locking member out of engaging relation with reference to the sash-face and for maintaining it out of such relation.

S. In an automatic sash fastener, the combination of a l easing constructed and arranged to be secured to the meeting rail of a lower sash and having a rear wall disA posed to incline therefrom over and away from the face of the other sash and provided with a longitudinal slot enlarged at one portion thereof, an automatic slidable wedge block mounted on said wall, and an operating pin mounted rotatively in said block and extending therefrom through said slot, said pin having its slot-occupying portion of a thickness adapted to be comprehended within the body of the slot and a width similarly related to the enlai-ged portion of the slot but greater than the width of the body thereof.

9. In an automatic sash fastener, the combination of an apertured plate constructed to be secured flat upon the upper face of the meeting rail of a lower sash, a easing formed integral therewith and having a rear wall disposed to incline therefrom over and away from the face of the other sash, and an automatic locking member longitudinally movable on said wall for coperation with the face of said other sash.
