SPECIFICATION forming part of Letters Patent N o. 423,751, dated MarchlS, 1890.

Application filed September 2, 1889. Serial No. 322,659.v (No model.)

To @ZZ whom it may concern.-

Be it known that we, FRANK FOWLER and AMOS M. ULMER, both citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Sash-Retaining Devices, of which the following is a speciiication.

' window frame and sash constructed in accordance with our invention, one of the side rails 4of the window-frame being removed and certain covering-plates onthe sash being detached in 'order to show the lbolt-operating mechanism carried by said sash. Fig. 2 is a section on the line l 2, Fig. 1, showing in elevation the b olt-operating mechanism at the side of the sash. Figs. 3 and i are yperspective views o f said bolt-operating mechanism,

showing it in two different positions. Fig. 5 1s a sectional plan view of the mechanism for effecting the locking of the`two sashes tospo gether. Fig. 6 is a vertical section of the same.

A represents part'of the fixed frame of a Window, a one of the side rails of the same, and'B the sash,guided in the frame, as usual.

Each of the side rails a of the windowframe has adjacent to one face of the sash a recessed bar or plate b, as shown in Fig. 2,A

and the sash has at each side a casing d,'with in which is pivoted a bolt f, the latter having slots g g located one abovethe pivot and one below the same, these slots receiving pins hh', projecting from a slide D, which is guided in the casing d and lis acted upon by a spring e., tending to depress it. The lower end of the slide, however, rests upon a rod 1T, and this in turn is supported by one arm of a lever F, hung within abox F at the lower corner of theY sash, the other arm of this lever being acted upon by a rod i', which is guided horizout-ally in the lower portion of the sash and is acted upon by a lever G, hung within a box G', let into theface of the sash, this lever G being acted upon by a spring j and by a lever H, also hung within the box G. Precisely the same mechanism is employed for each side of the sash, the two leversHbeing connected by a bridge-piece J, which is normally held in an elevated position by the action of the springs j upon the levers G,- the spring' e at each side of the sash consequently depressing the slide D, and thus causing the pins 71, h of said slide to so act upon the inclined slots in the locking-boltf as to thrust the same outward into a recess of the retaining bar or plate b on the side bar of the frame. Vhen lthe sash is closed, the looking-bolts engage with the lowermost recesses of the bars b, and hence lock the sash firmly in the closed position; but upon depressing the bridge-bar J the slides D will, through the medium of the levers and rods which we have described, be caused to rise, and their pins h h will act 'upon the locking-bolts f, so asto withdraw the same 'from engagement with the recessed retaining-bars, and the sash can then be raised to any desired extent, the locking-bolts being projected as soon as pressure is removed from the bridge-bar J, so that said bolts may be caused to engage with any desired recesses of vthe retaining-bars, and thus hold the sash Jnrmly in the desired position, effectually preventing either the riseor fall pf the sash or the rattling of the same in the frame.

Although we preferto provide each lockingbolt fwith two inclined slots, each receiving an operating-pin on the slide, but one slot need be used, if desired, and a single lever connected to the bridge-piece J and'acting on the bolt vl may replace the two levers G and H in some cases. VFor instance, the lever I-I only may be used, the construction shown, however, being preferred.

When it is desired to lock the mechanism, 4

so as to prevent tampering with it, a lever x, to be operated by asuitable key, may be used, this lever having bolts which enter open# ings in the levers H of the operating mechanism, so as to lock. the same in position, as,-

shown in Fig. 1. f

In order to lock two `sashes together, the top of the lower sash is provided with a casing M, in which is suitably guided a spring- IOO bolt N, adapted to engage with any one of a number of openings ina plate N on the face of the upper sash, this bolt being acted upon by a lever P, which is under control of the wedge-shaped upper end of the bar or slide D, which controls the bolt f, so that when the slide is raised the bolt N will be withdrawn and the sashes unlocked, as will be readily understood on reference to Figs. 5 and 6. The box or frame CZ is cut away at the top, as shown in-Figs. 3 and 4, so as to permit the slide D t0 extend up to the top ofthe sash and act on the lever P in the manner set forth. Having thus described our invention, we claim and desirevto secure by-Letters Patent- 1. The combination of a window-frame having recessed retaining-bars at opposite sides, with the sash having at each side a pivoted and slotted locking-bolt` for engaging with said retainer, a slide having pins adapted to the slotted portion ofV the bolt, so as to movethe same positively in both directions, and means for operating said slide, substantially as specified.

2. The combination of the frame of the window and its recessed retaining-bars, the sash having pivoted and slotted locking-bolts for engaging with said retaining-bars, slides having pins adapted to the slots of the bolts, so

as to move the same positively in bothk direc.- tions, horizontal rods guided on the sash near the bottom of the same, pivoted levers interposed between said rods and the bolt-operating-slides, and means for moving said rods longitudinally, substantially as-specified.

3. The combination of the frame-and its recessed retaining-plates, the rsash and its locking-bolts, the operating-slides for the latter, vertical and horizontal rods guided in the sash, levers interposed between ,said rods at the lower corners of the sash, and operating devices for the horizontal rods, comprising opposite pairs of levers engaging withv each 0ther,`0ne of said levers acting: uponfa horizontal rod and the other being connected by a bridge-piece to the opposite lever, substantially as specified.

4. The combination of the sashes, the spring-` bolt carried by the lower sash and engaging with openings in the upper sash,a slide actuating said bolt, and operating devices for ssl the slide carriedby said lower sash, substan 5o tially as speci-ned. t t

5. The combination of the frame and its recessed locking-bars, the upper sash having locking-openings, bolts carried by the lower sash and engaging with the upper sash and with the locking-bar of the frame, slides for actuating said bolts, and means for operating said slides, substantially as specified.

In testimony whereof we have` signed our names to this specification in the presence of 6o two subscribing witnesses.
