S'PEGIFIGETION forming part of Letters Patent No. 291,672, dated January 8', i884.

Application filed October 4 1883. (No model.)

I0 all whom it may concern;

Be it known that I, MARTIN BoUnKn, acitizen of the United States, residing at Youngstown, in the county of ,Mahoning andState of Ohio, have invented certain new and useful Improvements in Sash- Holders; and Ido here by declare that, the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of thisspecifioation, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a front elevation of ,a windOw, showing my improved sashholder connected thereto. Fig. 2 is an interior view of the sash-holder, showing the bolt drawn in from contact with the window casing or frame; Fig, ,3, a similar view, showing the bolt extended to bring it in contact with the window casing or frame when desired to hold, the sash stationary- Fig. 4 is a per spective View of the bolt-sections and bolt casing, or housing, showing'them disconnected from each other, and Fig. 5 a detail View of the twosections of bolt, illustrating the purpose of the inclined shoulder on the slot, and showing in dotted linestheposition of the pin immediately after passing over the shoulder.

The present invention has reference to certain new and useful improvements in that class of sash-holders in which is employed a horizontal bolt formed in two sections, the in-,

her section being operated by cam-actuattwo sections, the inner bolt-section being provided with a lever extending out through the diagonal slot for operating it, by which means said section, when moved in the arc of a circle, or, in other words, partially rotated, will at the same time be caused to move forward or outward in a horizontal line, tocome in contact with the outer bolt-section, and thus force the latter in frictional contact with the window-frame. In the above class of sash-holders the outer section of the bolt was in no way attached to or connected with the inner boltsection, but simply supported and retained in operative position by the bolt casing or housing, and prevented only fromdropping out by the window-frame. It is the .pur- "pose of the invention, therefore, to improve the construction of the sash holders above referred to, whereby the outer section of bolt is prevented from dropping out of its casing or housing and becoming lost when the sash is removed from the window-frame,1which ob ject I attain by a simple and effective means of attaching the two bolt-sections together, and at the same time admit of the inner sec tion being turned without turning the outer section, thereby providing for theaccidental dropping out and losing the outer section of bolt when it is found necessary to remove the window-sash.

In the accompanying drawings, A represents the window-frame, and B C the upper and lower sashes thereof, to which myimproved holder is connected, in the present instance it being shown as attached to the lower sash and in position to retain it closed.

The sash-holder consists of a casing or hous ing, D, and a bolt formed in two sections, E F, the former being provided with a handlever, G, of any suitable form and construction, by which said bolt-section is operated. :The casing or housing D is of the ordinary construction-that is to say, it is bottomless, and cast with an inclined or diagonal slot, or, and flanges b,for attaching it by screws to the window-sash. It does, however, differ in this respect from the housings or casings above referred to in that it has an inclined end, a, the purpose of which will be hereinafter described.

In the class of sash-holders hereinbefore referred to the two bolt -sections were unattached, the interior surface of the casing or housing forming a bearing for the outer section of the bolt to support it in operative position, thus necessitating more or less friction of the parts, and when: the sash is removed in most every instance the outer section of bolt would drop from its casing or housing and too frequently become lost. To remove these difficulties, in contradistinction from having the two bolt-sections unattached, I attach them together in the following manner: The lever G, as will be seen, extends out through the inclined or diagonal slot a, and the bolt-section E, with which the lever is integral, is .provided with a reduced end or shank, d, from which projects a small pin, 6. The outer boltsection, F, is-formed hollow a portion of its length to receive the reduced end or shank d of the section E, the outer section also having a T-shaped open slot, f, with which engages the pin 6 in the circumferential portion thereof.

By the above-described means the two boltsections E F are attached or connected together and prevented from being accidentally separated and the outer section lost when removing the sash from the window-frame. The outer section, however, can be removed from the inner section of the bolt by turning it sufficiently to bring the pin on a line with the open or longitudinal portion of the T-shaped slot. A further advantage in attaching the two bolt-sections together is that the weight of the outer section is taken from off the interior of the casing or housing, thereby preventing friction and wear of the parts, as would be the case were the outer section supported entirely by the casing or housing.

In order to take the entire weight of the lever G off the edge of the incline or diagonal slot at, and prevent too rapid wear byconstant friction of the two, the inner end of the boltsection E throughout its entire surface is formed inclined, as shown at g, to conform to the angle of inclination of the end 0 of the casing or housing. The two inclined surfaces, as above described, act together as a cam to force out or draw in the bolt-section E, and with it the outer section, F, thus notwholly depending on the action of the inclined or diagonal slot a, and also'preventing wear upon the edge of the slot to that extent as would impair its usefulness.

The outer section, E, if preferred, may be provided with a bearing-plate, H, to present to the window-frame a greater frictional surface when brought in contact therewith. The outer bolt-section, as well as the other parts of the sash-holder, are preferably cast of metal, and the plate H, if desired, may be made of wood, metal, or other suitable material, and secured to the bolt-section in any wellknown manner; but to facilitate the manufacture of the holders, I prefer the plate to be of metal and cast with the section, thus rendering it more durable. The circumferential portion of the T-shaped slot f, at the point where it joins with the longitudinal portion or open part of said slot, is formed with an inclined shoulder, h, as more clearly shown in Fig. 5, the advantage of which is as follows: When the bolt-section E is turned sufficiently to bring the pin 6 to the extremity of the inclined shoulder h, or at a pointindicated by full lines, by further turning the bolt-section the pin will ride over the shoulder and pass the longitudinal portion of the slot without catching on the side thereof, therounded corner 5 guiding it to the position as indicated by dotted lines, thereby preventing any possibility of the pin catching in the longitudinal portion of the T-shaped slotwhen the bolt-section is turned in the direction to draw in the outer section from contact with the window-frame. This is an important and essential feature of my invention, from the fact that without the inclined shoulder c, with the assistance of the rounded corner i, the pin 6 would frequently catch in theslot, as above described, resulting in the bending or twisting of the pin, and also rendering the device inoperative.

The shank d of the bolt-section E is of sufficient length, so that when inserted in the hol-' low end of the boltsection F the shoulder formed by the reduced end of the section E will not come in contact with the edge of the outer section, a space being left, as shown in Fig. 5, thus preventing any friction by the contacting surfaces at this point.

The bolt-section F is carried backward as well as forward by the action of the section E, but while the said section is moved both longitudinally and in the arc of a circle, the

sections being provided with a lever and a shank carrying a pin, and the other section being formed hollow, and having a T-shaped slot, by which means the two sections are detachably connected together, substantially as and for the purpose described.

2. A sash-holder'consisting of a bottomless diagonally-slotted housing containing a horizonal bolt formed in sections, having a handle, and a shank with pin upon one of said sections, and the other section having a T-shaped slot formed with an inclined shoulder to assist the pin in riding over and preventing it from falling in the straight or horizontal portion of the slot when the section is turned, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
