IEASTENER FOR QASEMENT-WINDOWS AND THE LIKE.

To all/whom it may concern."

Be it known that we, STANLEY EVERED and CHARnEs Wnmiuotr'r, subjects of the King ofGreat Britain, residing at No. 5

Rotton Park road, Birmingham, England, and No. 103 Galton road, Warley Woods, BirminghaimEngland, respectively; have in vented certain new and useful Improvements in Fasteners for Casement-Windows and the like, of which the following is a specification.

Our invention consists of the improvements hereinafter described in fasteners for casement windows,-doors and the like, the said improvements having for their principal objects to simplify the construction of the said fasteners, to render the. same very eiiicient in use and capableof right or left hand application as -may be desired, that is to say, capable of application to case- "ment windows and thelike hinged either at the right or left hand side of the windowframe. T

We will further describe the said invention in connection with the accompanying drawings.

a according as to whether the hinged casement 1s hinged at the right or left hand side, bears on the stud 6 when the window is closed and the handle is turned from the unfastened position indicated in dotted lines in Fig. 3 into the fastened position represented in Figs; 1 and 2 and'in full lines in Fig.3. The side of the pin 6 against which the cam-like surface a bears is preferably curved but the other side of the said pin or stud fe may be flat as is represented to lessen the distance which wouldotherwise be necessary between the cam part a and the face of the fixing plate 6.

When it is desired to open the hinged casement c the lever handle a is turned on itspivot d from the position represented in Figs. 1 and 2 into the position indicated in dotted lines in Fig. 3 so as thereby to bring the groove a between the two projecting cam-like partsar, into line'with the stud 6 when the casement cinay be pushed outwardly the groove a permitting the handle a to pass the pm orstudewithout obstruc- On closing the Window it is necessary to bring the lever handle a into a horizontal position so as to permit the said handle to repass the stud or pin e the handle being turned down into th'efastening position as soon as the groove a has passedover the said pin'or stud e the cam a? on the turning of the handle a into the vertical position coacting with the stud e to tightly close the casement c and holdit in the closed or fasten'ed positi'on y In order to prevent the person closing the easement a from turning the lever handle a beyond the vertical or fastening position represented in Figs. 1 and 3stops or ribs a are preferably formedat the bottom of the cam shaped parts a the said stops or ribs a serving to limit, by contact with the pin or Stud 6, the turning of the lever handle (t of the fastener. According to a modified arrangement of the fastener represented in plan in Fig. 4, wherein'the portion of the casement towhich the fastener is attached isin horizontal section, the pivot (Z of the handled is arranged nearer the fixing plate Z) than in the fastener represented inFigs. l, 2 and 3 and when the hinged. casement is closed the stud e ofthe reveal. of .thestationary frame of the window occupies the groove 4 in the acting end of the handle a of the-fastener as is illustrated in the said Fig. 4, consequently on the turning of the handle a in one or other direction from the horizontal or unfastening position one of the sides of the groove a is brought to bear on the stud e and effect the .tight closing of the hinged casement. r

WVhere the channel or groove a in the handle a engages with the stud e in the manner hereinbefore described with reference to Fig. 4 the acting end of the handle a may be made without the steps or ribs (1 hereinbefore described with reference to the arrangement in Figs. 1, 2 and 3 the said handle of the fastener Fig. t being represented in side elevation in Fig. 5. a

We wish it to be understood that we do not limit ourselves to any particular shape or construction of the parts as the same may be varied without affecting the utility of the invention. For example, the pin or stud e on the fixing plate f may be made hollow as is represented in section in Fig. 6 instead of being made solid. Further, where the fixing plate carrying the stud 0 cannot be fixed to the reveal of the stationary frame of the window the construction of the part carrying the stud e is modified as is illustrated in Figs. 7, 8 and 9 or as is illustrated in Figs. 10 and 11. Figs. 7, 8 and 9 represent, the improved fastener on a window casement in elevation, plan and plan, partly. in section, the easement being closed and fastened in Figs. 7 and 8 and unfastened and the asement partly open in Fig. 9. Fig. 10 is an elevation and Fig. 11 an end elevation of the alternative form or construction hereinbefore referred to.

Where the channel or groove a of the handle a engages with the stud e in the manner illustrated in Figs. 4:, 7, 8 and 9 the handle part of the fastener may have the shape or form illustrated in Figs, 12, 18 and 14 which represent respectively a front elevation, inner face view and plan of the handle and fixing plate of the same. v

Where, as in applying the fasteners to the door or doors of a French window or other like door, the same is to be used at the top and bottom of the window the channeled or grooved part which is to engage with the projecting stud on the stationary frame of the window is preferably made on the end of a vertical spindle which occupies a tubular socket resembling the barrel or casing of an ordinary sliding door bolt. The partial rotation of the spindle through a quadrant in one or other direction effects the fastening and unfastening of the window.

This arrangement of the said invention is illustrated in elevation in Figs. '15 and 16, the parts being in the fastened positions in Fig. 15 and in the unfastened positions in Fig. 16. Fig.1? is a horizontal section on the dotted line 17-17 Fig. 15 and Fig. 18 is a vertical section on the dotted line 18-18 Fig. 15.

The horizontal slot h in which the handle a works has preferably in one edge a notch 2' to permit the vertical spindle of the fastener to drop slightly .so as to carry the acting end below the stud e as is represented in Fig. 16 and thereby prevent the spindle turning when the door is open and obviate the possible damage which wouldresult should the door be closed with force with the closed side of the slottedfend of the fastener presented to the pin or stud e.

Figs. '19 and 20 are elevations at right angles to one another of a double arrangement of the fastener whereby the fastening of the door at top andbottom may be simultaneously effected.

We claim y 1. A fastener for. hinged easements comprising a pin or stud for attachment to the stationary casement frame, and a rotary member for attachment to the hinged casement frame tocooperate with said pin or stud and providedwith means for actuating the same,said;rotary member having in its acting "end a channel with two opposing walls to receive said pin'or stud when said member is partially rotated.
