Application rues September 5, 191?.

To all whom it may concern:

Be it known that l, thorn-inn llI1IWSAM,CllJlzenot the United States, residing at Peoria Heights, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in VVindow-Latclies, and do hereby declare-that the following is a full, clear, and exact description of the invention, which will enable others inn drawing, wherein,

skilled in the art to which it appertains to make and use the same,

This invention relates to a window latch.

It )ertains more iarticularlv to a latch used as a support for window sashes generally, being especially adapted for sashes of railway coaches.

One of the objects of the invention is to provide a latch operated by gravity loc-ated in a window casing adjacent the runway of the sash. so arranged that when the sash-has been raised above the position or" the latch,

said latch will automatically and positively fall into position by gravity where it will receive upon the said sash, and which can be raised and moved out of "2163 path of the sash all without complication oi any kind.

Another object is to provide an exceedingly simple form of latch whose parts cannot be broken nor get out of order, and that can be made at low cost. i

To the end that the invention may be understood, l have lpi'o -xided theaccompany- Figure 1 represents an elevation of a part of a sash andits window casing in vertical section and my invention applied thereto, one of the parts being in position to support the sash.

Fig. 2 is a similar view with the described part raised out of use. i Fig. 3 shows, in perspective, a slotted plate e cutcheon. p l v 4. shox vs, in perspective, a latch; and, Fig. 5 is a horizontal section ot' a window casing and sash showing my invention ap plied thereto, part being shown in section,

Sash locks as ordinarily furnished for coach windows are easily damaged and easily rendered useless because of their flimsy construction, besides offering endless opportunities for injury to the fingers. Such locks when damaged prevent the sash being moved at all, requiring that a new lock be installed wh1ch means a constant expense.

My device to be described, however, is

exceedingly strong, easy to operate, entirely efl'ective, and once installed is a permanent,

winDow-Laroir.

, quired.

1 indi:-ates a part of a window casing, 2 the sash, and 3 the usual stops between which the sash 2 slides. 4: indicates a recess formed in the casing 1 opposite the edge oi the sash.

5 is an escutcheon-plate mortised into the casing 1 so that its front surface will lie flush with the bottom of the slide in which the edge of the sash 2 is carried.

This plate is provided with a vertical slot 6, the metal being preferably cutaway around said slot to provide a beveled surface 7. Also, by preference, opposite edges oil the plate are provided at the rear with a flanggjc 8 creating a recess atthe rear side of the plate, the recess 4 in the casing 1 correspond- .ing in width thereto, as clearly shown in opposite the described slot 6 and if theplate 5 is a stamping, the tongue may be that part of the plate that is cut out to torm the slot and at its lower end preferably terminates at the bottom of the slot substantially as shown in Fig. As shown in Fig. 3, however, the tongue may be secured to the back of the plate.

In the several figures, especially in F g. l, is shown what I shall term a latch. It is preferably of a single part made up of a portion 10 in the form of a plate from one end of which extends. substantially at right angles, a neck-portion 11 with a head 12. Preferably the under side of the neck is rounded asat 13 to lend strength thereto. The said neck 11 and the head 12 are of a width hat will readily pass through the slot 6 of the plate The portion 10, however. is much wider so as not to pass through the slot. being substantially equal, in width to the ninth of the recess and the space or recess between the flanges 8. This is most In Fig. 1 the latch in its lowermost position for supporting the sash It rests in the bottom of the slot 6, the portion 10 bears ing against the inner or. rear side of the plate 5 while the head 12 rests against the outer surface of the plate, projecting intoth'e path of the sash. This constitutes an absolutely firm support for the sash, therebeing no possible chance of the sash falling.

The sash in order to be lowered must first be raised until. its lower edge is at or above the upper end of the slot 6 whereupon the operator may raise the latch with the finger until said latch takes theposition shown in Fig. 2 at the top of the slot. the head '12 having been moved upward and backward until it is moved entirely out of the path of movement ofthe sash.

In pushing the finger up to lift the latch it will naturally encounter the lower end or point of the head 12 and as the head moves upward in and inward through the slot. the portion 10 will fall forward and follow up upon the inner side of the plate 5, or the heel- 10 of the latch may follow up the tongue, the upward movement being arrested as the head strikes and reaches the upper end of the slot. Said head will now lie outside of the path of the sash and the latter can be lowered past it without difliculty, said latch being maintained in the position in which it is placed by resting against the edge of said sash. The latter can be readily raised and lowered without interference.

When the sash is raised to a position to release the latch the latter'will at once drop down by gravity to its position in the path of the sash. being guided thereto by the tongue 9. The rear wall of the recess t may be formed to correspond to the slant ofthetongue 9 to act in the same capacity as the latter. It is preferred to use the tongue, however, since it provides a smooth working surface for the latch and will always have the proper position with relation to the plate 5 and for that reason the attachment can be readily and quickly set into a recess which has not been required to be exactly formed.

Several of the described devices may be placed in position in the runway of the sash at various heights so that said sash may be held at any desired place. The metal is beveled around the slot 6 in order that the finger will not be injured by chance raw edges of metal. at the slot 6 when pushing the latch up.

My device because of its form can be placed in the runway of the sash and, therefore, is not visible except beneath the sash when the latter is raised, being only partially visible when the sash rests upon the latch. When the sash is closed nothing whatever projects from or mars the appearance of the casing or the sash.

neonate My device is distinguished from others of its class in being of a simple construction that ca'nnot be disarranged in use and that does not require a special knowledge of its manner of manipulation. In the use of one of the devices of said class each person must inform himself by actual trial the manner of operating the latch because of its peculiar form whereas in. my device the mere lifting of the latch causes it disposal with? in the casing out of the line of movement of the sash.

Having thus described myinvention, I.

claim 1. A device for supporting a window sash comprising in combination, a plate having a vertically disposed. slot, a part extending from substantially the bottom of the slot upwardly at an angle away from the plane of said plate and a latch including in its construction a tongue adapted in one of its positions to lie in and extend. through said slot and having a portion of a width greater than that of the slot to lie against the inner side of said plate, said latch having an angled recess at its forward part creating a ledge to lie outside said slot upon which to support the sash. 1

2. In a device for supporting a window sash, in combination, a plate located in the bottom of the runway of the window frame having a vertically arranged slot, 3 part upwardly and rearwardly inclined from substantially the bottom of the said slot, and a latch comprising a portion greater in width than the slot arranged in one of its positions to lie against the plate at that side adjacent the said inclined part, and including a ledge spaced from said portion to eXtend outwardly through the slot in the sash supporting position for receiving the sash upon it. r

3. In a devicefor supporting a window sash, in combination, a plate located in the bottom of the runway of the window frame having a vertically rranged slot extending therethrough, a part inclined upwardly and inwardly from substantially the bottom of said slot, and a latch slidable within and through the slot adapted in one of its positions to lie wholly inward from the outer face of the plate and in another of its positions to extend partially through the said slot outside the plate in the path of the sash the part thereof extending through the slot including an abrupt ledge to-rreceive the sash upon it. a y a V In testimony whereof I affix my signature in presence of two witnesses.
