Application filed June 18, 1925. `58111211110.:V 38,043.

and State of Ohio, have inventcd certain.

ncwand. useful.lmprovements in Window Locke; and I do declare the following to be a full,.clear,,zand eiiact description ofthc .'invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

My inventionzaims vto provide an ,exceptlonally simple and inexpensive, yet an efiicient and desirable device which is'adapted forquick and easy application to a window.

and may be used for holding the upper and lower sashes in any desiredrelatively adj usted positions.

The device comprises in general, a guide member adapted to be mounted on the upper rail of the lower window sash, and a wedgc sliclably engaged with said guide member, further objects being to provide a wedge and a guide member of unique construction, and to make novel provision for holding the wedge in an inoperative position when its use is not desired.

T/Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a perspective view showing the application of the invention.

Figure 2 is a Vertical sectional view illustrating the wedge'in operative position in full lines and by dotted lines showing its inoperative position. v

Figures 3 and 11 are perspective views of the wec ge looking in different directions.

Figures 5 and 6v are perspectiveviews of the guide member looking in different directions. V

The drawing above briefly described may be considered as illustra-ting the preferred .form of the invention and while the construction shown will be hereinafter rather specifically described, it is to be understood at the outset that within the scope of the invention as claimed, modifications may be made.

The numeral 1 designates in a general way, a wedge guiding member. This member comprises a substantally Vertical plate .2 having a Vcentral neck 3 projecting upwardly from .its upper edge, said neck. being ;provided withoppositely projecting fingers Al. The end portions 5 of the upper edge of .the plate 2, forn'i shoulders at opposite sides of theneck 3 for a purpose to be heremafter' cxplained, and at the ends of these shoulders, lugs 6 are bcnt laterally from one side of the plate. The upper. end of the ncck 3 is preferably curved in the same direction in which these lugs entend, as shown, and the. =lower end of theplatc 2 has been shown bent in this samedirection to provide a horizontal .led'e 8. eVertical wings 9 Dro'ect in the o J- posite directionfrom the :plate 2, at the vertical edges of the latter, the-lowerends of these wings being bent latorally inward to provide attaching feet 10 which are= adapted to be secur-ed by screws or Vthe like 11 tO the upper rail 12 of a lower window sash.

The entire guide member 1 is preferably stamped from a single piece of suitable gauge sheet metal, as will be clear from the drawing.

At 13, I have shown a hollow wedge formed of sheet metal, one side wall ofsaid wedgebeing produced by inwardly bending a pair of fianges 14; from two adj acent side walls, as shown, a space being left between the two flanges, forining a longitudinal slot 15. There is also an open space 16 between i? the upper ends of the flanges 14. and the upper end of the wedge. slidably engage the Shoulders 5, and the neck 3 passes through thelslot 15, the fingers 4' then slidably engaging the inner sides of said flanges. In this connection, it Vmay be explalned that these fingers are passed through the opening 16, when assembling the device. In addition to the guiding influence exerted by the fia-nges 14, neck 3, fingers ll and shoulders 5, it 'ill be seen that the lugs 6 embrace the wedge 13 to further guide the same. The side of the wedge, opposite the flanges 14;, is preferably provided with spurs 17 outwardly stamped therefrom to engage one of the side rails of an upper sash, when the wedge is in the operative position shown in Figs. 1 and 2. However, when the use of this wedge is not needed, it may be raised and its lower end 18 then engaged with the ledge 8 as shown in dotted lines in Fig. 2. The wedge is held in either position, against accidental upward movement, by a coiled tension spring 19 whoselower end is connected tothe neok 3 while its upper end is The fianges 14 l suitably connected to the upper end of the Wedge, the latter being` preferably provided With a tongue 20Vfor this purpose.

Normally, it may be considered that the wedge 13 occupies the dotted line position of Fig. 2, so as torpermit free sliding of the sashes. 7lien they have been relatively adjusted however, the Wedge may be easily inoved off of the ledge 8 so that the spring` 19 snaps it downward into operative position, thus eifectively looking both sashes.

On account of the advantages existing for the details shown, they are preterably followed7 but as above stated, n'iodifications may be made Within the scope of the Vinvention as claiined.

I cla'iin:

1. A sash fastencr comprising a guide member adapted to he secured to the upper rail of a lower sash, said guide n'i-emher having` a. ledge, and a spi'ing-lo\i"e1'ed Wedge slidably engaged With said guide member, said Wedge being' adapted to bd tilted and disposed ou said ledge when not in use, Whereby it is hold against lo\\"n\vard moveinent.

2. A sash fastener comprising a guide member adapted to he secured to the upper rail of a lower sash, said guide member having an upstanding necl: and horizontal Shoulders at opposite sides thereof, said neck being` provided With oppositely projecting fingers spaced from said Shoulders,V and a hollow VWedge having a longitudinalV slot in one side Wall through which vsaid neck passes, the aforesaid Shoulders engaging the outer side of said Wall and said fingers engaging the inner side thereof.

3. A sash fastener coinprising` a substantially Vertical sheet metal plate having,` Wedge-guiding` means at its upper end, the lower end of said plate being bent horizontally to provide a ledge at one side of the plate, Vertical Wings bent la-terally froin the plate and projecting from the other side thereof, said Wings having' horizontally bent lower ends forming attaching feet, a Wedge slidahly engaged with said Wedge guiding means and adapted to rest on said ledge when not in use, and spring means connectinf; said Wedge and plate and exerting a downward Stress on the former.

In testimony Whereof I have hereunto affixed my signature.

GRANT L. HOUSTEAU.
