Specification of Letters Patent.

Application filed June 17, 1909. Serial No. 562,698.

T 0 all whom itgnay' concern:

- Be it known that I, OLIVER M. Eownnns, a citizen of the United States, residing in the city of Syracuse, county of Onondaga, State of New York, have invented a certain new and useful Improvement in Sash-Holding Devices, of which the following is a full, clear, and exact. description, reference being had to the drawing accompanying the same.

My invention relates generally to holding or locking devices for windows and similar structures; and more particularly to that class which is provided with a shaft. to which the holding or looking dog is secured. ()ne object of my invention is to provide a holding or locking device of the class mentioned having a shaft which controls the.

looking or holding dog with a support adapted to resist the 'thrust given to the dog, as by a falling sash or otherwise.

Another object is to provide such a holding or locking device with a casing, a portion of which projects from the surface on which it is mounted and is adapted to receive the shaft and operating means therefor theprojecting portion of the casing being adapted to form a portion of the operating means.

Another object isto provide a holding or locking device having a shaft, one arm of which serves as the holding or looking dog with a casing adapted to be mounted on and project from the-surface of the sash without letting the shaft of the holding device for its-whole diameter into the stile or sash to which the casing is attached, thereby'permitting-of the extension of theshaft and casing to the extreme edge of the sash without unduly weakening the same or interfering with the stop bead on the frame behind which the holding or locking-dog is arranged.

Another object is to provide such a hold.-

-ing or locking device with a cewing forming a support for the shaft and that portion of the dog opposite the end thereof which receives the thrust 1n holding the sash in the open position.

Other objects will appear from the description hereinafter given.

The invention .consists in the combinations herein set forth and particularly pointed out in theclaims hereunto an exed and which form a portio of thisSpecificatiOn.

F gure 1 shows mfi'ont elevation the corner portion of a window sash and frame to which is attached one embodiment ofJny invention, a portion of the guideway opposite the holding or looking dog being broken away for the better illustration of the parts there shown. Fig. 2 shows in vertical section the window frame with the sash and a portion of the holding meansin side elevation as seen on line 2 2 of. Fig. 1. sholvs in horizontal section that which is seen on line 3-3-of Fig. 1, but with the guideway complete and the dog in posi- Patented Dec. *7, 1909.

tion for the holding device to hold the sash at that point tightly in the window frame. Fig. 4 shows in vertical section that which is seen on line l l of Fig. 1 when looking from left to right.

Like letters of reference, wherever they I occur, indicate corresponding parts ofthe several figures of the drawing.

In practice it has been found desirable to make window sash, such for instance as are usually used in passenger cars, withcomparatively thin stiles and when holding or locking-means havin'g a shaft with arms attached thereto for-holding the sash in the desired position are applied tosuch sashes the shaft portions of such devices have to be either so placed on the sash that the stop bead against which. the dog of the holding device acts is some distance away from the sash, which is objectionable, or the shaft portion of the device has to belet into the stile which unduly weakens the sash. It is desirable in this class of sash holding locking devices having a shaft'which is provided with an arm to serve as a dog or holding part that such w-hi'ch coact with the guideway and form an ornamental trim or finish to such guidewayin which the sash moves in opening'and."

1 105. frame having closing the window.

A represents the Window the guideway a, in which the sash moves, a portion of which may be removable or notes desired, and B represents the window sash to which the dog or holding art and easing are attached, so that such he ding device is carried bylthe sashand moved correspondingly as the sash moves. The holding holding device is used in the manner seen in the drawing the fore finger of the hand or locking device C has a casing 0 in which .the shaft D provided with an arm (1 preferably formed integral therewith, as shown, is mounted, so as to have partial rotation in its bearings formed in the casing. The casing 0 is preferably provided with'flanges having laterally extending ears or portions which point in opposite directions, as shown, which are adapted to receive screws or other fastening devices for securing that portion of the casing firmly to the sash, the other end of the casing being preferably without ears and adapted to receive fastening or other securing means by which it may be secured in positionon the sash. These laterally extending ears are somewhat widely separated from one another and, consequently, that portion of the casing which is most liable to displacement or damage in use is securely held to the sash. The formation of the flange portions of the casin as showmpermits of these holding devices being used on sashes having extremely narrow bottom rails and side stiles as the end of the'casing farthest from the holding device may extend along the bottom rail while the extending ears are attached to the side stile and one ear portion may extend considerably beyond the point where the bottom rail joins the side stile. The casing 0 has the extension 0 which extends, as seen in Figs. 1 and 2, to the edge of the sash B which is in the guideway a of the window frame. The extension 0 with the inwardly projecting portion of the casing is prefer ably arranged relatively to the shaft 1) as shown, so that no portion of such extension extends beyond the outer line of such shaft and there is a greater thickness of material adjacent to nearly opposite portions of the shaft than there is between such portions, is more particularly seen in Figs. 3 and 4c of the drawings, that is, ,there is a less thickness of material in the casing and extension at the bottom of the depression than there is near the outer edges thereof. This permits of the sash being cut to a less depth than would be the case if the semicircular portion of the extension and easing, which is'to be received in the depression in the sash, were concentric with the axis of the shaft. This arrangementof the extension e and casing affords the same support to the shaft 4 and holding dog that would be afforded if such portions were concentric with such axis. The outwardly circular projecting portion of the casing c is preferably arranged substantiallyconcentric with the axis of the shaft D and it is preferably provided with a still further projecting portion which, with the circular portion, forms a portion of the operating means 0 by which the sash is opened and closed and the shaft D moved sufficiently to release the sash and permit it 54 0 move freely-in the guideway. lVhen the of the operator engages with the under side of the projecting portions of the casing and such portions form a lift by which the sash can be lifted in opening the same. Such portions also form a support for the hand of the operator when he grasps or presses down upon the movable part of the operating means with his thumb in controlling the holding dog and the movements of the sash. As shown the movable portion '0' of the operating means is the upper one of the two seen in Figs. 1, 2 and 4 of the drawings and tomove the dog out of holding position such upper portion is moved toward the fixed or stationary lower 'portion 0 which forms the lift for the sash; It will be observed that theprojecting portions of the casing do not interfere with the use of the device as the operating means are actuated precisely the same and occupy no more space than they would occupy if there were no projecting circular portions of the casing.

The shaft D has mounted thereon a spring S, the tension of which tends to move the holding or locking dog into holding or looking position. The shaft D is also provided with operating means 0 consisting, as shown, of a stationary lift or finger piece 0 prefcrably'formed integral with the cars ing 0 and a thumb or movable finger piece 0 preferably secured to the shaft 1), the parts 0 and 0 being so related to one another that when the movable fingeror thumb piece 0' is moved toward the stationary portion 0, the free end of the holding dog will be moved toward the'sash B and thereby be moved out of holding position, releasing the sash so as to permit it to move freely in the guideway.

It will be observed that the spring S and the parts 0 and 0 form operating means by which the holding or locking dog is moved in one direction by the tension of the spring and such dog is moved in the opposite direction by the movable thumb or finger piece 0 being moved against the tension of such spring. It will also be observed that the free end of the part 0 will move in a circle concentric with the axis of the shaft D and consequently the circular portion of the casingavill not interfere with the use of the operating means.

The form of holding or locking means herein shown may be used in connection with a sash and frame such as are herein set forth having surfaces for the holding or looking dog to coact with of the form shown in Figs. 1 and 2. or with sashes and frameshaving bthcr specific forms of coacting surfaces ibr the holding or locking dog and other surfaces for such'dog to coact with, as desired. These coacting surfaces may be formed on a strip, as I, or they may be other- .lll)

wise formed as desired. When used as herein shown the surface e on dog (Z engages wlth the surface 2' on the strip I attached to the frame of the window in the guideway to guideway by the tension of the spring S acting on the dog d through the shaft D.

Also the surface e of the dog d engages with the surfaces 2' on the strip I secured to the frame in the guideway, and pressure' 'appliedto such surface e tends to move the opposite portion of the dog (Z into close contact with the support formed on the extension 0 of the casing. The surfaces and the dog as (Z may be formed as herein shown or in any other desired manner adapted to do the work of holding the sash in the guideway, as the specific form ofsurfaees for the dog, as d, and the surfaces with whichthe dog coacts do not form aness ential part of the present invention.

\Vhat I have herein shown and described will naturally suggest to those skilled in this art somewhat different embodiments of this invention than the specific one herein illus trated, therefore, I do not wishto limit myself to the one herein set forth, but wish to include all embodiments which contain the spirit of this invention as particularly Y pointed out in the claims hereunto annexed forming a portion of this specification.
