SASH-HOLDER.

SPECIFICATION formingpart of Letters Patent No. 792,185, dated June 13, 1905. Application filed November 30, 1904. Serial No. 234,942.

To all whom, it may concern:

' Be it known that I, JosIArr WELnoN, a citizen of the United States, residing at Elmore, in the county of Ottawa and State of Ohio, have invented a new and useful Sash-Holder, of which the following is a Specification.

This invention relates to sash-holders.

The objects of the invention are to provide a cheap and thoroughly reliable form of holder which will in a positive manner hold a windowsash at any desired point of adjustment and in which the adjustment cannot be destroyed by upward or downward force applied to the sash; to adapt the holder for various positions upon the sash-that is to say, to adapt it to be mortised in the sash or to be secured to the outside thereof in the manner of an ordinary lock; to dispense with the employment of rivets in combining the locking-head with the carrier, whereby the construction of the device will be simplified and the coaction between the head and the carrier be rendered more durable in use; in a novel manner to limit the contact of the locking-head with the part with which it coacts, thereby to prevent bruising or marring of such part, and in a positive manner to limit the retractile movement of the carrier, thereby to enable the operator always to know when the locking-head is moved to a point where it will not contact with any part of the window-frame.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a sash-support, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there are illustrated two forms of embodiment of the invention, each capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in the drawings Figure l is a view in elevation, partly in section, exhibiting a portion of the sash-rail and the wind ow*frame,the former having combined therewith one form of embodiment of sash-holder. Fig. 2 is a detached detail View of the carrier. Fig. 3 is a detached detail view of the carrier-operating cam. Fig. 4 is a view in horizontal section, taken on the line 4 4, Fig. 1. Fig. 5 is a perspective detail view of a modified form of sash-holder. Fig. 6 is a detail perspective view showing the casing of Fig. '5 in a reversed position. Fig. 7 is a perspective detail view of the casing shown in Figs. 5 and 6. Fig. 8 is a transverse sectional view through the'casing shown in Fig. 5, the operative mechanism being removed.

The mechanism for holding the sash is the same in all the figures, the only difference being in the construction of the casing to adapt the holder to be positioned in different ways. Thus in the form shown in Figs. 1 and 4 the casing is designed to be mortised into the edge of the sash-rail, whereas in the form of easing shown in Figs. 5 and 6 it is designed to be sunk into one side of the sash-rail or to project beyond the same as an ordinary lock, thus to cause the locking-head to engage either with the window-frame or with the stop-bead.

Referring to the drawings and to Figs. 1, 2, 3, and 1 thereof, 1 designates a portion of an ordinary sash-rail, and 2 a portion of an ordinary window-frame. The sash-rail is provided with a mortise 3, in which is seated the casing 5, the same comprising a rectangular body portion, preferably open at both ends and provided at one end with lateral flanges 11, through which pass screws 12 to hold the casing in position. Mounted within the easing isacarrierd, one side of which is provided throughout the greater portion of its length with a chamber 13, from the wall of which project a plurality of segmental threads 14:, three in this instance being shown, although it is to be understood that this number may be increased if found necessary or desirable. The end wall 18 of the carrier is provided interiorly with a shoulder or stop 15 and exteriorly with a socket 17, which extends entirely across the wall and is engaged by the rounded terminal 21. of the locking-head 19, the same having a reduced neck 20 to permit extended rocking motion of the head and having on its outer face teeth or serrations 22, adapted to bite into the woodof the part with which it coacts, thus positively to lock the window against movement. By the provision of the socket 17 and cylindrical terminal 21 the head is combined with the carrier in such manner as positively to preclude its becoming separated, and, further, the union between these parts is exceedingly strong and durable. Furthermore, by this means of connecting the head of the carrier the employment of a rivet, such as usually employed, is dispensed with and the danger of breakage thereof reduced to a minimum. The forward or outer end of the carrier is provided with two extensions 18 and 18, which constitute stops and terminate short of the outer face or serrated portion of the head-and serve to limit the force of contact between the head and the part with which it coacts, thereby to prevent marring or damaging to such part, it being obvious that after the teeth have sunk into the part with which they coact until the stops contact with the part further sinking will be prevented, the stops being also adjunctive to the locking-head in holding the window at any desired adjustment. Arranged within the carrier is a cam 10, having a volute flange 16, which is designed to engage with the threads 14: and effect, when the cam is turned, the projection and retraction of the carrier. This cam has combined with it a hollow shoulder 9, which projects through an opening 8 in the top or cap plate of the casing. The orifice 10 through the shoulder is preferably square to receive the shank of a knob 23, by which the cam is turned, the shank of the knob 23 to be combined with the cam in any manner that will render accidental separation practically impossible. The entering end 16 of the cam is square and is designed to engage with the shoulder or stop 15, as clearly shown in Fig. 1, thus to check the backward movement of the carrier when the same has been moved to the position where the outer or serrated face of the locking-head is out of contact with the part of the window-frame with which it coacts. The operation of this form of the invention is as follows: The window being raised to the desired point, the knob 23 is turned in the appropriate direction, causing the flange of the cam by coacting with the threads 14: to project the carrier laterally and bring the locking-head into engagement with the window-frame. As the thrust from the weight of the window is at right angles to its length, it will be seen that the locking effected between the parts of the window is positive and will effectively resist any attempt to raise or lower the window without first releasing the locking-head from. engagement with the window-sash.

In the form of embodiment of the invention shown in Figs. 5, 6, and 7. the only difference is in the construction of the casing, this being adapted for reversal, whereas the form of casing shown in Figs. 1 to 4: is capable of being positioned only in one way. The modified form of easing comprises a base-plate 24, two side members 25, and a top plate 26, and an end wall 27, all the parts being, by preference, cast integral. Both the base-plate 2 1 and the cap 26 are provided with an opening 28 and 29, respectively, which are disposed in alinement with each other, and these openings are adapted to be engaged: by the shoulder 9 of the cam. \Nhere the casing is disposed exteriorly of the sash-raihas shown in Fig. 5, the shoulder will project through the opening 29 inthe plate 26;. but Where the easing is sunk or mortised into the sash-rail the position of the carrier and. the cam will be reversed, so that the shoulder 9 of the latter will project throughthe opening 28, as shown in Fig. 6. By the provision of this reversible j casing added utility is imparted to the device and the necessity of the provision of right and left casings will be obviated. Where the casing is positioned as shown in Fig. 5, the locking-head will engage with the stop-bead 30, (shown in Fig. 1;) but where positioned as shown in Fig. 6 it will. engage with a sashframe in the same manner as that shown in Fig. 1.

From. the foregoing description it will be seen that the devices of this invention combine in a simple and practical manner all the elements essential tothe presentation of a thoroughly eflicient and durable form of sashholder, and, further, owing to the simplicity of the parts, dangerof derangement in use is reduced to'a minimum.

Having thus described the invention, what is claimed is 1. In a sash-holder,.a casing, a carrier there in provided with a locking-head and. with segmental threads, a cam coacting with the threads to project or retract the carrier and having a hollow shoulder projecting through the cas ing, and an operating-knob having a shank seated within the shoulder.
