SASH FA STENER AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 573,439, dated December 22, 1896.

Applicatidn filed July 31,1896, $erial No. 601,127. (No model.)

To ctZZ whom, it may concern.

. Be it known that I, J AMES BENJ. OAHooN,

New York, have invented certain new and useful Improvements in Window-Sash Fasteners and Supports,of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to an improvement in window-sash fasteners and supports, the

means for automatically locking and supporting windows, whereby the necessity of using ropes and weights is obviated.

The invention will be hereinafter fully described and specifically set forth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of aportion of the window-frame having my improved device attached thereto. Fig. 2 is an inverted sectional plan taken on a line 00 0c of Fig. 1. Fig. 3is asectional plan view taken on a liney'y of Fig. 1, and Fig. 4 is a sectional plan view taken on a line .2 e of Fig. 1.

In the practice of my invention the upper sash A and the lower sash B are both provided, respectively, with grooves a and b throughout nearly the entire length of the right-hand vertical portion of their frames. Into these said grooves are secured racks O, which said racks engage with pinions D. These said pinions are connected to beveled gear-wheels E, and these said beveled gearwheels engage with other beveled gear-wheels F, all of the said parts being mounted within casings G,'which are set within recesses g of the window-frame A. The pinions D and their beveled gear-wheels E are journaled upon shafts d, and the beveled gear-wheels Fare mounted on shafts f, which said shafts fare journaled within the side walls of the casings G. Secured also to the shafts f are coiled springs H, which said springs are normally in an unwound or loose condition, and their free ends are attached to pins h of the casings G. These said springs are adapted to retain the windows in position, as will be hereinafter described. A

Located within recesses of the upper and lower sash A and B, respectively, are casings :I, and mounted within these casings are longitudinally-movable spring-pressed bolts J, which said bolts are normally maintained in outward positions by means of springs J, and they are adapted to engage with recesses a of the window-frame A, and when the windows are closed these said bolts will automatically engage with the said recesses for locking the windows. object thereof being to provide an efficient I As a means for fastening the bolts and retaining them in an unlocked position, as illustratedin the upper sash in Fig. lof the drawings, I provide spring-pressed pawls K, which engage with projections of the bolts J, and as a means for operating the said bolts J or unlocking the same I provide levers L and L, respectively, for operating bolts of the upper and lower sashes. These said levers are journaled upon pins Z, which are secured to the casings I.

The lever L for operating the bolt of the upper sash is provided upon its inner end with a slot Z, which engages with a pin j of the bolt J. The outer end of the lever L engages with a rod M, which passes longitudinally through the vertical framework of the sash A, whereby the bolt may be released from its recess Ct for unlocking the window when it is desired to lower the upper sash.

The lever L for operating the bolt J of the lower sash is connected at its inner end to a toggle-lever Z which engages with a pin of the bolt J. This said lever L has its end extended through the front of the vertical framework of the lower sash, whereby the bolt J may be operated for unlocking the window when it is desired to raise the said lower sash.

In the operation of the device with relation to the lower sash when it isentirely closed or lowered, as illustrated in Fig. 1 of the drawings, the pawls K will be thrown out of engagement with the projection j of the bolt J by means of the said pawls contacting with the pinion B,whereby the bolt will be released and its spring J will automatically shoot it into its recess a, thus locking the window. When it is desired to raise the window, the bolt J willbe thrown into position (illustrated in Fig. 3 of the drawings) by means of the lever L. The pawl K will then spring into engagement with the projection j of the bolt J and maintain the same in an unlocked position until the window is again lowered to a depth sufficientto allow the pinions D to throw the pawl out of engagement with the stop or projection j. The operation of locking and unlocking the upper sash is precisely the same, with the exception that the lever L is operated through the medium of the rod M.

The springs H are normally in a looselywound condition, and the act of windin g them respectively by the action of lowering the upper sash and lowering the lower one will cause the windows to be maintained in any desired open position without the means of either ropes or weights.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a sash fastening and hanging apparatus, the combination of a pinion and beveled gearing and a coiled spring located within the window-frame and a Vertical rack upon the edge of the window-sash engaging with the said pinion and beveled gearing, and a springpressed bolt also located within the windowsash and means for automatically operating said bolt comprising a spring-pressed pawl which engages with the pinion of the said gearing of the frame and with a projection of the said bolt, substantially as shown and described.

2. As a means for fastening and hanging windows, the combination of a Vertical rack secured Within the edge of the window-sash and a pinion engaging with said rack secured within a recess of the window-frame, said pinion being in engagement with a beveled gearing,which gearing is secured to a coiled spring for maintaining the sash in position; with a spring-pressed bolt which is secured within a recess of the sash and a spring-pressed pawl for engagement with the said bolt, said pawl adapted to be automatically operated by means of the said pinion, and means for independently operating the bolt comprising a lever attached thereto which leads through the framework of the sash, substantially as shown and described.

In testimony that I claim the foregoing as myinvention I have signed myname, in presence of two witnesses, this 28th day of July, 1896.

JAMES BEN-T. CAIIOON.
