`To allwhom tlnmy concern: y Y

Be it known `that we, GEORGE W.`WRIGHT f and OSBORN RCOOKE, both of Salem, in the l county of Golumbianaand State of Ohio, have invented anew and useful Improvement in Sash-Holders, of which the following is a specification:

Our invention relates to sash-holders in which acatchsecured in a recess of the winthroughout the rods whole length; and our invention consists in the combination and arrangement `of a 'plvoted lever secured to the window-frame with a catch arranged-upon a c rod secured within the sash, said pivoted lever being entirely ,free from the biting-catch, but having a convenient fixed arrangement on the frame for operating to release its bite. Our inventionalso consists in the manner of securing the rod of the biting-catch within the window-sash without fastenings and it furtherconsists in the construction of the pivoted lever so as to operate in connection with a recess in the frame and the catch secured within said recess, but loose at one end, to lock the lower sash when down.

In the accompanying drawing, Figure 1 represents a vertical section through a window frame and sash to which our improvement is applied, the lline of section being through the lower sash. ppFig. 2 represents a similar view, the line of section being through the upper tsash. Fig. 3" represents a vertical cross-section `in line x w, Figyl, showing the arrangement of the catches for the upper and lower sashes on an enlarged scale; andFig. 4 is detached perspective view of a sash with the rod and -holding-catch.

In one side of each sash of a window are' formedgrooves a., extending from the upper to the lower end of the sash. In these grooves a. metal rods b are arranged, their upper and lower ends being bent at right angles, as shown at b', and passed into openings formed in the groove centrally at top and bottom. At

suitable points of the side of the windowfframe, a and in line with the rods b, areformed recesses c of sufficient depth to admit about onethird of the length of metal catches d, which are secured in the recesses c, by means of staples e, in such a manner as to leave to theouter ends of these catches a vibrating or free up-and-down movement. The outer ends of l these catches d are provided with openings f',

vvhich may be round or slightly oblong, and through whichV the rods b pass, so that,`in raising or lowering'the sash, the rods b must slide throu gh the openings f in the metal catchesd, 1which latter accommodate themselves, to a certain extent, to the up-and-down movement of the rods b and the sash.

It will be readily understood that when the sash is raised and the rods b pass upwardly through the openings f in the ends of the catches d the gravity of the latter and the position of the pivoted levers prevent them from vbeing raised by their frictional contact with i the raising-rods b, and thereby binding. upon or biting them to pre-vent their further upward movement; but when the sash and rods are lowered the natural tendency of the catches d is to fall by their own gravity untilthey have reached such an angle that the openings f bite on the rods b and-prevent their further downward movement, thus holding them and their sash at that point. In order to lower the sash, therefore, the catch d must be raised and kept in nearly a. horizontal position to prevent them from biting on the rods b. This we accomplish by means of levers g g', one of which is used for each sash. We have vshown the lower lever g constructed with a forked inner end, h, which seizes over the catch d, and with a slot, i, through which `a screw passes, which holds the lever to the frame and forms its pivot, and by means of which slot t the 1ever g may be arranged more or less inwardly, as may be found most convenient, to operate the catch and to lock the lower sash when down. The upper lever g represents another form which may be used, it not being provided Another important advantage of the lower lever g consists in having it p All" n 1 the function of locking the sash when down7 so that the latter cannot be raised from the outside of the window. This is accomplished by enlarging the recess c, within which the pivoted lever g is secured, so as to form an upper recess7 c', to receive the upper branch l of the said lever when it is drawn out the limit of the slot fi, and the kn ob 7c turned down, as shown by dotted lines in Fig. 3, and thus elevate the catch d so that it will bite upon the rod b by an upward inclination, and prevent the raising of the sash until the lever is again turned down to bring the catch d to a horizontal position,

, as shown in Iig. l of the drawing.

To lower the upper sash or raise the lower one the knobs k ofthe levers g g are depressed, thereby raising the respective catches d and allowing the rods b to pass through their openings j) but the moment the knobs 7c of the levers g g are raised the inner ends of the latter are lowered and the catches allowed to fall and bite upon the rods b, thereby instantly au Hi g their movement and holding them and h ir sash firmly in place at that point.

Our device is of cheap construction and not liable to get out of ordenand can be easily attached to any window. The parts being all of met l they are not liable to suf 1 injury, but p 1 inng ofrougher usage l au with most sash-stopping devices.

Hav ng described our invention, we claim- 1. The riveted lever g, in combination with the catch Z secured in a recess of the frame, and the sash-rod b, arranged for joint operation as described.

2. The sash-rod I), secured in place by its bent ends to admit of easy attachment and removal, as described.

3. The pivoted lever g', with its slot i and stop-branch l, in combination with the upper recess c in the frame, for the purpose of locking` the lower sash when down, as described.

d. The rods b secured to the sash and hidden from viewthroughout their Whole length, in combination with the dog or catch d' secured Within a recess in the Window-frame, and provided With a suitable opening, f, to obtain the proper biting-surface upon the rod, substantially as described.
