SHEET-METAL VIINDOW.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed April 14, 1909. Serial No. 489,794.

To all whom it may concern:

Be it known that I, ALEXANDER FROM- HOLD, a citizen of the United States, residing at the borough of Rutherford, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Sheet-Metal lVindows, of which the following is a specification. This invention relates to improvements in sheet metal windows and refers more specifically to improvements in the stops or guides whereby the sash are confined and guided.

Among the salient objects of the invention are to provide extremely simple, cheaply constructed and entirely reliable means of adjustably securing the stops in their seats in the window frame; to provide in such mechanism means for adjusting one or more of the stops laterally, 2'. 6. toward or from the sash frame without in any degree impairing the reliability with which the stop is secured in position and without substantially adding to the cost of construction; and in general to provide improvements in the stop mechanism of a window of the char- 1 acter referred to.

To the above ends the invention consists in the matters hereinafter described, and more particularly pointed out in the ap pended claims.

In the drawingsFigure 1 is a fragmentary perspective View showing in perspective a portion of one of the side frame members and fragmentary portions of the upper and lower sash seated therein; Fig. 2 is a cross sectional view of the window frame shown in Fig. 1; the sash being omitted; Fig. 3 is a detail cross sectional view of the adjustable stop member and the parts of the frame within which it is seated; Fig. at is a longitudinal sectional view taken centrally through the detachable parting strip stop.

Referring to the drawing, 1 designates as a whole a. side casing member of a sheet metal window frame, which is in its general construction similar to those now in common use. In the innerface of the frame member are formed two parallel grooves, as 2 and 3 adapted to respectively receive an adjustable stop at and a detachable parting strip stop 5. An integral outer stop 6 is also shown.

Describing first the adjustable stop 4, the walls of the groove 2 form upon the interior of the hollow frame 1 a rib 7, and at frequent intervals apart, say at intervals of one foot, are inserted through this rib metal strap-like anchors 8; these anchors being inserted loosely through suitable slots 9 in the opposite sides of the rib 7 in position to hold the anchors 8 parallel with the inner face of the frame member 1. Each anchor is suitably apertured about midlength and threaded to receive the end of a screw 10 inserted through the outer face wall of the stop; the anchors being set far enough above the bottom of the stop groove so that the end of the screw will not encounter the bottom of the groove when extended slightly through the anchor. The adjustable stop is made considerably wider than the width of the stop groove which it overlies and preferably has only one of its side members or walls extended into the groove, as indicated at 11. This extension 11 constitutes a stop which limits the movement of the stop member laterally in one direction by encountering the side wall of the stop groove, while the body of the screw 10 by encountering the opposite side wall of the groove limits the movement of the stop laterally in the opposite direction. These two limits of movement are such as to prevent the stop member from being moved in either direction sufliciently to expose the stop groove. IVhen it is desired to adjust the stop toward or away from the sash, the series of screws which engage the anchors are simply loosened slightly, thus freeing the anchors so that they may slide endwise, whereupon the stop may be forced over laterally to any degree within the limits of adjustment described. Having been properly adjusted, the screws are tightened, and by drawing the anchors against their seats in the rib 7, look the stop in adjusted position.

Describing, now, the detachable parting strip stop, the internal rib 7 which forms the groove 3 is apertured and provided with a series of anchors 12 constructed and ar- -ranged substantially or precisely as described in connection with the adjustable stop. In a substantially similar way a series of screws 13 are inserted through the face wall of the parting strip and into the anchors 12, but in this instance the side walls of the or interfere with the anchors they are notched out, as indicated at 14-, in position to register with each of the several anchors.

In order to reinforce the face wall of the parting strip, and at the same time permit the heads of the screws 13 to be let into the strip, so as to lie flush with the latter, reinforcing strips 15 are inserted and riveted to the face wall at each side of each screw aperture, as indicated at 16. The heads of the screws are countersunk into the double thick wall thus formed.

It will be obvious that the mechanism described fully attains the several objects of the invention hereinbefore stated. It will be further obvious that the details of construction and arrangement may be modified without in any sense departing from the spirit of the invention, and accordingly the claims hereto appended are not to be understood as limited to the specific construction shown, except in so far as they are specific to de tails.

I claim as my invention:

1. In a window, a casing frame provided with a stop groove, a stop engaging said groove, and means for adjusting and locking said stop in any position of adjustment com prising an anchor plate slidably mounted in slots formed in the sides of said groove, and a. locking bolt extending through said stop into said plate.

2. In a window, a casing frame provided with'a stop groove, a stop engaging said groove, a plurality of anchor plates slidably mounted in slots formed in the sides of the groove, and locking bolts extending through I said stop into the respective anchor plates.

3. The combination with a casing frame, provided with a stop groove, of a stop engaging said groove, and means for adjusting and locking said stop in any position of adjustment comprising a laterally movable anchor plate seated in said groove, a locking bolt extending through said stop and engaging said plate.

4. In a window, a casing frame provided with a stop groove, the latter forming an integral rib, a stop engaging said groove and means for locking said stop to the casing comprising an anchor plate movably mounted in said rib and a screw extending through I the stop and into said plate.

In a window, the combination of a casing frame provided with a stop groove, a stop engaging said groove and having a right angled extension extending into the groove, an anchor plate movably mounted in slots formed in the sides of said groove, and a locking bolt extending through said stop and engaging said plate.
