SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 730,996, dated June 16, 1903. Application filed November 3, 1902. Serial No. 129,920. (No model.)

To all whom it may concern:

Be it known that I, LA FAYETTE TNVEVER, a citizen of the United States, residing at Arran, in. the county of Wakulla and State of Florida, have invented a new and useful Sash- Holder, of which the following is a specification.

This invention relates to devices employed for supporting window-sashes, and has forits object the production of a simply-constructed device readily applicable to any of the various sizes of window-sash, but which is more particularly designed for use upon railroad-car windows.

The invention consists in certain novelfeatures of construction, as hereinafter shown and described, and specified in the claims following.

In the drawings illustrative of the invention, Figure 1 is a side elevation of a portion ofawindow sash and frame with the improved device applied thereto. Fig. 2 is a transverse section, enlarged, on the line 11 II of Fig. 1. Fig. 3 is a transverse section, enlarged, on the line III III of Fig. 1.

The device may be applied to any of the various sizes of sliding sash and similar structures, but is more particularly designed for use upon the window-sash of railway-cars, and for the purpose of illustration a portion of a window frame and sash of this character is shown with the improvement applied thereto, the sash being indicated atlO, the frame at 11, and the inside stop at 17. q

The improved device consists of a keeper 12, attached to the sash and located at a comparatively remote distance from the adjacent portion of the casing or frame, the keeper having an overhanging portion 13, as shown more clearly in Fig. 2.

Pivotally connected to .the keeper 12 be-. tween the overhanging portion and the sash, as by a pivot 14, is a lock-bar 15, the outer or free end 16 of the lock-bar extending to and in engagement with the adjacent face of the stop 17, the engaging face being below a transverse line passing through the pivot 14:, as shown in Fig. 1. The outer end of the lockbar 15 will be provided, preferably, with rubber, leather, or other suitable yieldable material 18 to prevent abrasion of the stop or casing and also to increase the frictional grip. The lock-bar will be provided with a thumbgriplQ, extending therefrom, as shown, and the pivotal'end of the lock-bar when formed of wood WlllbG provided with a metal wearplate 20 in engagement with the overhanging portion of' the keeper to prevent wear on the bar.

Attached to the sash 10 adjacent to the bar 15 is a combined guide-plate and lift portion, the lift portion being indicated at 22. The plate 21 will be provided with a lip 23, extending over the bar 15 and forming a guide thereto and preventing any lateral movement to the bar. The cavity formed by the lip 23 extends downwardly for some distance to provide for the requisite downward movement of the bar, the recess thereby formed being occupied by a spring 24:, exerting its force to maintain the lock-bar in its upward or operative position relative to the stop 17. The lift 22 and the thumb-grip 19 will preferably be insubstantial vertical alinement, so that the operator by placing his forefinger beneath the lift 22, with his thumb upon the grip 19, may depress the bar 15 and release 'it from engagement with the stop 17 thereby releasing the sash and permitting it to be lowered.

By arranging the free end of the bar 15 below the transverse alinement of the pivot 14 it will be obvious that the sash may be moved upward without reference to the bar 15, as the upward movement of the sash will cause the bar to release itself from the stop, the improved device thus offering no hindrance to the elevation of the sash; but the moment any downward movement takes place the bar 15 will bite into the stop 17 and be transformed into an instantaneous lockbar, and thus effectually prevent any downward movement of the sash.

The guide-plate 21, together with its liftlug 22, is an important feature of theinven- 5 provides for supporting the spring 24, so that extra attachments are not required to secure the spring.

The parts may be made of wood or metal, the parts 21 12 being preferably of metal and the part 15 of hard wood, with the wear-plate 2O employed to prevent undue friction between the bar and the overhanging portion 13 of the keeper. The'bar 15 may also be formed entirely of metal, if preferred, with the thumb-grip integral therewith.

This makes a very simple, complete, and efiective sash-lock, formed of few parts, and consequently not liable to become disarranged and very eifective and certain in its action. All of the parts are readily accessible and easily replaced when broken or worn.

The device is equally elfective upon the largest or the smallest sash and may be manufactured and sold at a very low cost, as all the parts may be cast, and will require very little machine-work.

The device may be manufactured of brass or other similar metal and highly polished or of any other desired metal, and the parts may be formed in fanciful designs and plated, japanned, or otherwise coated or protected.

Having thus described the invention, what is claimed is 1. A sash-lock comprising a lock-bar pivotally connected to the sash by one end and provided with an extended thumb-grip, and with its free end in engagement with the window frame or stop out of horizontal alinement with said pivoted end, a guide-plate attached to the sash and extending over the end of said lock-bar and provided with an extended lift-lug, and a spring disposed to maintain said lock-bar normally in operative relation with the window stop or frame, substantially as described.

2. A sash-lock comprising a keeper overhanging at one end and attached to the sash, a lock-bar pivotally connected to said keeper beneath said overhanging end and with a wear-plate between the bar and keeper, said lock-bar provided with a thumb-grip and engaging the window stop or frame out of horizontal alinement with said keeper, a guidebracket attached to said sash and overlapping the lock-bar and having a lift-lug extending therefrom, and a spring between said guide-bracket and lock-bar and exerting its force to maintain said lock-bar normally in operative position, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
