1Toy all whom/ it may concern:

Beit known that LDANIEL GREEN SAUN- DERS, Jr., a citizen of the United States, and a resident of Kansas City, Missouri, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a spe'cication containing a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof. My invention relates to a sash-fastener; and the object of my invention is to construct a simple inexpensive device which is attached to window-sash and which while allowing said sash to be slightly opened for the purposes of ventilation yet locks said sash very securely together and prevents their being opened by a person on the outside of the window.

A further object of my invention is to constructa lock-plate and bolt-casin of sheet metal in order to greatly reduce t e cost of manufacture of the device;

A further object of my invention is to so construct a sash-fastener that when the locking-bolt is' turned in a certain position the meeting-rails of the sash will be drawn together, so as to form avtight joint between the two sash.

ltive view of the My invention consists of a lock-plate adapted to be fixed to one ofthe side rails of theV upper window-sash and a locking-bolt movably held in ahousing that is carried by the top rail ofthe lower sash.

My invention further consists in certain novel features of construction and arrangements of parts, that will be hereinafter shown, described, and claimed.

In the drawings, Figure 1 is a perspective view of my improvedsash-fastener, the same being applied to the sash of a window. Fig. 2 is a vertical section takenon the line 2 2 of Fig. 1. Fig. 3 is on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of the locking-bolt made use of in carrying out my invention. Fig. 5 is a perspeclower portion of a modified form of the locking-plate of my improved device.

Referring by numerals to the accompanying drawings, 1 indicates the vside rail of the upper sash, and 2 the meeting-rail Vof said upper sash. 3 indicatesthefsiderail of the lower sash, and 4 the meeting-rail thereof. These rails are all of the usual construction, and the sash are arranged to slide vertically in the locking-plate is rigidly fixed to the means of screws 8 a horizontal section takeny than are the f a uarter of a turn usual parting-strip 5. Y

The locking-plate of my improved` device is preferably stamped from sheet metal and is located on side rail 1.- This locking-plate comprises a vertical strip 6 of'sheet metal, having its side edges 7 bent rearwardly and adapted to rest directly upon the face ofthe rail 1. This A y rail 1 by vices. rearwardly at an angle to form an inclined face 9 at the upper end of the locking-plate. Formed in the strip 6,- below the inclined upper end thereof, is a series of rectangularapertures 10, which are formed vby unching out the material in the strip 6 an bending the punched-out material inwardly fromthe lower ends of said apertures 10, so that they form in clined or beveled faces 11, that extend from the lower portions of the apertures 10 upwardly and inwardly to the face of the side rail 1. Immediately below the lowermost one of these apertures 10 is an aperture 12, considerably wider than the aperturesl 10, which wide aperture 12 is made by punching out the material in the face of the strip 6. This punchedout material is bent inwardly and extends from the lower end of the aperture 12 upwardlyk and inwardly to the face of the rail 1, thus forming an inclined face 13. Immediately below the aperture 12 adjacent the lower end of the strip 6, is an aperture 14, the-same being preferably of equal width with the apertures 10.

Positioned on top of the rail 3 of the lower sash end of the locking-plate 'just described is a sheet-metal housing 14, in which is arranged for horizontal movementthe shank of a lockng-bolt 15. Passing ,through this lockingthe face of the lower end of the and immediately in front of the lower usual window-casing being separated bythe or similar fastening de- The upper end of this strip 6 is bent t inside the housing 14 is a pin 16, and lol cated upon said said pin and the ing is an expansive coil-spring 17. The rear end of the shank of the bolt 15 is provided with a square head 18, that is adapted to en-k ter the apertures 10, 12, and 14, and Said square head 18 is slightly narrower in width apertures 10 andl4a; but it is ofsuch length that when 'the bolt 15 is given the end of saidhead 18 wi l engage behind the-edges of the front'wall bolt 'and interposed between front end wall of said hous roo IIO

of the` locking-plate adjacent the apertures 10 and 14E.

The front end 19 of the housing 14 is beveled off or formed on an angle, and the rear end of the bolt 15, that projects beyond this end wall, is formed into a small crank-handle 20. This crank-handle 20 is so formed that when it is moved downwardly in either direction to rock the bolt 15 the vertical arm of said crank-handle will engage against the beveled face 19 of the housing, and as a result the rear end of the bolt 15, carrying the head 18, will be drawn forwardly a slight distance, and when the head 18 is engaged in any one of the apertures of the lockinglate the tendency will be to draw said locfingplate and the upper sash into close engagement with the lower sash.

In Fi 5 I have shown a modified form of the locking-plate, which modified form consists of a flat plate 7a, preferably sheet metal, from which is stamped vertical ribs 7b, between which are formed recesses 10a, which correspond to the apertures 10, previously described, and inclined faces 11a are formed between the ribs 7 b which inclined faces corf respond to the inclined faces 11, previously described.

In the use of my improved sash-fastener the head 18 on the end of the bolt 15 passes through an aperture 14a of the locking-plate when the sash of the window are closed, and when the bolt 15 is rocked the ends of the head 18 will engage behind the side edges of the aperture 14 and the crank 20 on the forward end of the bolt 15 will bear on the inclined face 19, and as a result the bolt will be moved a slight distance forwardly through the housing 14, and the meeting-rails of the sash will be tightly drawn together. The head of the bolt 15 is drawn into the space between the lower end of the locking-plate and the rear end of the housing 14 by pulling the bolt 15 forwardly, thus compressing the spring 17, and when in this position either or both of the sash may be moved vertically, as desired. rIhe bolt is heldin this withdrawn position by swinging the crank-handle 2O downwardly into a horizontal position. The upper sash can be lowered or the lower sash raised a short distance, and said sash can be locked together, allowing the head 18 of the locking-bolt to engage any one of the apertures 10.

The aperture 12 is made purposely wide in order that the head 18 will pass into said aperture, even though it be turned into a horizontal plane, in which position it will not pass through any of the a ertures 10 or the aperture 14a, owing to t e fact that it is greater in length than is thewidth of said apertures.

A sash-fastener of my improved construction can be very cheaply manufactured, inasmuch as the main parts thereof` can be readily stamped from sheet metal, and the device is very easily applied to window-sasli and forms a very simple, easily operated, and effective fastener.

I claim- 1. In a sash-fastener, the combination with a housing secured to one of the sash and provided with a series of openings through its front wall one of which is wider than t ie remaining openings there being inclined facesA extending upwardly and rearwardly from the lower edges of said openings, of a housing secured to the opposite sash, and a locking-bolt movably positioned in said housing, which locking-bolt is provided at its forward end with an elongated rectangular head of such width as to enter any of t ie apertures while in a vertical position, and the ends of the head adapted to engage behind both side edges of the openings when the bolt is rotated a quarter of a turn; substantially as specified.

2. In a sash-fastener, a housing fitted-to one of the sash, a locking-bolt arranged for rotation therein, an elongated head integral with the forward end of the locking-bolt, and a vertically-arranged housing on the opposite sash provided in its front wall with a series of rectangular openings of such size as to receive the rectangular head of the lockingbolt while the saine is in vertical osition, and one of said a ertures being wi ened in order to receive tiie rectangular head when the same is in a horizontal position 3 substantially as specified.

3. A sash-fastener,constructed with a housing secured to one of the sash and provided with a series of openings throu h its front wall one of which openings is wi er than the remaining openings, there being inclined faces extending upwardly and rearwardly from the lower edges of all of the openings, and the upper end of the housing being inclined upwardly and rearwardly, a housing secured to the opposite sash, a locking-bolt movably ositioned in saidlast-mentioned housing wliich locking-bolt is provided with an elongated rectangular head at its forward end which head is adapted to enter any of the narrow openings in the first-mentioned housing while in a vertical position, and to enter the wide opening while in a horizontal position; substantially as specified.

In Atestimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
