OF PERU, INDIANA SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 250,562, dated December 6, 1881.

Application filed July 9, 1881. (Model.)

To all whom it may concern:

Be it known that I, LAWRENCE MCCALL, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful Improve ments in Sash-Fasteners; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of relerence marked thereon.

Figure 10f the drawings is a front elevation of a window frame and sash, partly in section, showing the application of my invention. Fig. 2 is a detail view of the spring-rod-fastening device, with a portion of the window-sash in dotted lilies, showing the position of the fastening device. with relation to the notches upon the sash. Fig. 3 is a perspective view of the window-frame, with the molding connected thereto for concealing the fastening device; and Fig. 4: is a plan view of the same with the molding removed.

The present invention has relation to that class of sash fasteners or locks composed of a spring-arm or other like device adapted to engage with notches or a serrated bar on the window-sash for holding it at any height or fastening the sash closed, as desired.

Previous to my invention the particular construction of these fastening devices rendered them very expensive as well as difficult in applying to the window-frame. Ordinarily these fasteners were provided with a knob, button, or other device for operating them, which were disposed upon the outside of the Window-frame in view. Therefore it was an easy matter for a person on the outside of the window to break one or more of the panes of glass, reach his hand through, release the fastening device by pressing upon the knob or button, disengage it from the sash and raise the same, thereby affor ding no security against thieves unless the well-known locking devices operated with a key are employed, which are notonlyexpensive and com pl,icated,as a general thing, but are at times impracticable.

The object of my invention is to provide a simple, cheap, and practical fastening device that can be readily attached to the windowframe with comparatively slight alteration of the same, thereby enabling it to be sold in sets in the marketready for immediate appli cation to the window-frame, and when thus connected and the window-sash fastened the sash cannot be opened by any one on the outside by breaking a paneof glass and reaching his hand through, as the manner of connecting it to the window-frame completely conceals it from view, requiring a suitable key to operate it. These objects I attain by the construction substantially as shown in the drawings and hereinafter described.

In the accompanying drawings, Arepresents the window-frame, and B the sash, said frame having connected thereto a suitable molding, a, which extends around its four sides. The sash B is provided upon one of its edges with inclined notches b and a notch, c, with which the fastening device engages when it is desired to fasten the windowclosed,theinclined notches serving to hold the window-sash open at any height required.

The fastening device is of peculiar form, it being composed of a steel or other spring-wire, O, of sufficient length to give it the required elasticity. The wire 0 is disposed within arecess, d, formed in the frame A, the lower end ofthe wire being bent at right angles, as shown at 9, so that it may be driven in the frame A, this being all that is necessary to securely fasten the wire to the frame. The opposite or upper end of the wire 0 is bent at aright angle, as shown at e, and again at right angles, as shown atf, Fig.2. The wire forming the lastmentionedangleis of sufficientlengthto form a wide and firm bearing for the face of the notches b,and consequentlyacompletelock for the sash.

An opening, h, is formed in the frame A at the upper end of the recess d, and at a right angle thereto, to receive the angle f of the wire and allow it to move horizontallyin the opening to releaseit from the. inclined notches b or notch 0.

The moldings a 'i, which are ordinarily used in window-frames, serve to completely conceal the fastening device from view.

To operate the fastening a suitable key is necessary, its shank being flat and inserted into the narrow opening k through the molding i, and by pressing down or outward the angle fof the Wire 0 the same will be disengaged from the notches in the sash.

too

As the fastening device is wholly concealed by the moldings a z", should a person from the outside break the glass for the purpose of raising or opening the window the fastening device could not be operated without possession of the key, thereby making the fastening a very secure one against parties from the outside.

The manner of bending the wire 0 is deemed of importance, it not only forming a complete fastening device, but one that is simple, easy of attachment to the window-frame, and that can be manufactured at atrifling cost, there being no additional springs or other devices necessary to render it operative, or screws or other similar fastenings for securing it to the sash.

The entire fastening device, as will be seen, is composed simply of a piece of spring-wire bent in theform shown, and. as heretofore, there is no knob or button on the end of the fastening for operating it, nor is it composed ot'sheet metal. This latter form, although common,is

not COUSidrlQd practical, as the sheet metal is not as strong and durable as the wire, and besides there is increased expensein their manufacture, as well as making it, in most cases, necessary to use screws to connect them to the window-sash, while my device is connected by the staple end 9. Having now fully described my invention what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the window-sash B, having the notches b c, of the spring-wire 0, having the staple end g, for attaching it to the window-frame, and atits opposite end beat, as shown and described, to form the two angles ef, said wire being disposed within the recesses d h of the frame and concealed from view by the moldings ad, the latter having an opening, 7c. through it for the reception of a suitable key for operating the fastening device, substantially as and for the purpose set forth.

2. As an improved article of manufacture, a sash-fastening device consisting of the springwire 0, bent, as shown and described, to form the two angles 6]", and at its opposite end bent to form a staple, g, for attaching it to the window-frame, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

LAWRENCE MCOALL.
