GEORGE E. FORSYTH, OF CHICAGO, ILLINOIS.
SASH CONSTRUCTION.
To all whom it may concern Be it known that I, GEORGE H. FORSYTH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash Constructlons, of which the followingis a specification.
This invention'relates to improvements in sash constructions, the several features of improvement being more es ecially, although not exclusively, applica le to hollow sheet metal sash.
Among the objects of the invention areto produce a tight, dust-excluding, but easily operable sash, characterized by the provision of a relatively large area of dust-excluding contact between the sash and its guide; to provide new and improved means, preferably automatic, for adjusting the sash 'to variations in width both of the sash-guide and of the. sash opening; t0 provide new and improved means for. balancing or supporting the sash in' such a way as to tend to maintain thesash centrally of the openin and support the sash equally on both si es; ,to provide new and improved means for holdin the sash when lowered against the sill un er tension; to providenew and improved means for releasing both the sashholding or locking means and the sash-adjusting means and to provide a new and improved joint for the meeting members of the sash.v w
To these and other minor ends the invention' consists in the novel features of construction and combinations of parts hereinafter more particularly described and pointed out in theclaims.
The invention wiIlbe readily understood whenconsidered in connection with the accom anying drawings showing practical Inec anlcal embodiments of the same, wherein,--
Figure "1 is a side elevational view, broken out and partly in'vei'tical section, of a hollow sheet metal sash constructed and equipped in accordance with the present inventlon. Fig. 2 isa cross-sectional view on the line 2-2 of Fig. 1, looking downwardly. Fig. 3is a similar cross-sectional view on the linedf-B of Fig. 1, looking duwnwardly. Figs. 4, :5 andfi are'detail views in vertical section through the pinch-handle opening of the sash, more particularly illustrating the means for releasing the sash-locking and ad- Speciflcation of Letters Patent.
Patented Aug. 4,- 1914;.
justing means from the pinch-handles and maintainin -a permanent closure of the pinch-hand 'e'opening; and Fig. 7 is a crosssectional view similarto Fig. 2, illustrating a modification of the sash-adjusting means.
Referring to the drawings, 10 may desighate as an entirety the upper and lower crossbars of the sash, and 11 the vertical stiles, which parts may, as herein shown, be pressed or otherwise constructed from sheet metal so as to have a hollow or outwardly-opening channel form. u
12 indicates a side post of the frame, to which may be secured the sash-guide, this latter as shown in Figs. 1 and 2 consisting of a pair of suitably bent metal strips 13 havin parallel walls 13 and inwardly turne inclined lips or flanges 13?.
Referring now to the sash-adjusting means, which means may also tend to hold the sash in adjusted position, and which, as herein shown,-are contained within the hollow stiles 11, 14 designates bearing blocks secured to the inner transverse wall of the stile, in which bearing blocks are pivotally mounted on pivot-pins 15 a series of thrust-members each consisting of a pair of arallel short' links 16 lyin in the lane 0 the sash, on the outer ends of eac of which links are pivotally hung a pair of adjusting strips 17. These latter are formed, as most clearly shown in Fig. 2, with wedge-shaped outer margins that are adapted to be guided be tween the-straight and inclined walls 13 and 13" of the sash-guide whe'n said strips are raised, the action of which is to thrust or force the-side walls of the stile into a snug dust-excluding contact with the parallel side walls of.the guide, and also to force the inclined or beveled edges of the adjustingstrips into similar snug dust-excluding contact with the inclined lips or flanges 13 of the guide, thus afl'ordin a relatively large and extended area of ust-excluding contact. This action also tends to crowd the sides of the sash into snug engagement with the guides so as to partially or wholly support the'sash and also to adjust the sash laterally of the opening as well as transversely of the guides. In efl'ecting these results I also employ means for producing normally a lifting or supporting tendency on the thrust-members 16 and, incidentally, to some extent a lifting or supporting tendenoy on the sash itself, which means may consist of a tape or cord 18 secured at. one or both ends to a suitable sash-balance (not shown) and passing around and beneath the pulleys 19 mounted in the upper ends of vertical extensions 20 of the u per pair of thrust-links 16 on either side 0 the sash. To transmit this tendency from the upper pair of thrust-members to the series lying therebelow, as also to effect the release of the adj usting means when desired to raise the sash, I have herein shown arod 21 that passes through swiveled bearing blocks 22 mountedin and between the thrust-links 16 of each pair, said lifting rod having cotter or stop pins 23 extending therethrough suitably engaging the bearing-blocks 22; and the lower end of the-rod 21 on each side having a pivotal link connection 24 With a releasing lever 25. This latter is pivoted intermediate its ends on a suitable pivot-pin extending bee tween the side Walls of the lower bar of the sash, such a pin being shown at 26 and at its inner end threaded into a washer 27'that may be riveted in the rear wall of the sashbar as indicated at 28.
In the bottom of the sash is slidably mounted between guides 29 and 30 independently secured to the opposite side walls ofthe sash, so as not to interfere with the transverse,resiliency'of the side walls of the stile, a plunger 31,-the outer' end of which is tapered or inclined on its upper side, as shown at 32 to fit beneath a correspond-- ingly-shapedundercut of the guide flanges 13", said plunger being normally pressed into locking position by a compression spring 33 confined between the'inner end of the plunger and a stop 34 on the lower wall of the sash-bar. The inner end of the plunger has an upwardly projecting contact lug 35 adapted to be engaged for, the retraction of the plunger by the depending arm 36 of a bell-crank lever, the hub 37 of which is pi'votally mounted on the pivot-pin 26 that carries lever 25, while the inwardly ex-' tending arm 38 of the bell-crank lever is provided with a laterally projecting thumb- .piece 39' extending through an arc-shaped slot 40 in'the side wall of the sash-bar and cotiperating with a stationary pinch-handle or finger-piece 41 riveted to" the side wall of the sash-bar directly above the opening. The arm 38 of the bell-crank is further pro-- vided with an inwardly projecting In 42 (Fig. 3) lying beneath the inwardly pro ecting arm of lever 25, which latter stops shortof the transverse plane of the opening 40- and overlies the path of movement of the Lug 42. From the foregoing it will be seen that when the pinch-handles-39 and 41 are compressed, the bell-crank is first moved to carry its depending arm- 36 into engagement with the contact-lug 35 of the plunger; on the further closing movement of the. pinchhandles the plunger is withdrawn-from beneath the guide-flanges 13", at which time the lug 42 reaches and strikes the inwardly projecting arm of lever 25, thereby raising said arm and consequently depressing the outer arm and the releasing rod 21, which retracts the adjusting strips 17 and thus releases the hold of the sash on its guides whereby it nay be easily slid up and down. The steps last described in connectionwith the compressing of the pinch- handles 39 and 41 are well illustrated in the detail viewslatter I have further shown the inner armof the bell-crank as provided with a vertical plate 43 of somewhat greater width than the slot 40, as shown in Fig. 1', and of suflicientheight to cover the opening in all positions of the pinch-handles.
In order to prevent'the possibility ofthe thrust-members 16 from passing beyond the. horizontal position, any suitable stop device may be employed, such devices being herein illustrated as stop-blocks 44 (Fig. 1) riveted to one or both'sides of thesash stile just above the thrust-members so asnot to interfere with the transverse resiliency of the side walls of the sash stile. In this connection I may state that the side walls of the sash .stile may or may not be so formed as, whe'n inserted in the guide, to exert a lateral pressure against the walls of the guide underi their own resiliency. I In Fig. 7 I have illustrated a of the sash-adjusting means, wherein I have shown a plain channel-shaped guide-strip 45 secured to the post or side wall of the casingwithinwhich' guide are a pair of inmodification versely disposed vertical strips 46- oftriangular form in cross-section, with their oblique sides outwardly convergent, thus forming a wedge-shaped groovebetween them;
and I have shown pivoted to the ends of the thrust-bars 16 an adjusting-strip 47 having a corresponding wedge-shaped outer edge adapted to engage the wedge-shaped groove or channel formed by and between the strips 46. The strips 46may be vertically stationary, or they may be vertically movable with the sash, as shown, being connected to the latter by. pins 4.6 engaging transverse slots 11 in thesides of the sash stile to permit the necessary in and out play of said strips 46. In connection with "Fig. 2 Imay also mention that while I have shown the guiding flanges .or lips 13 as elastic strips. intethey might'be separate from the guides, '13 or might be replaced'by a solid or rigid beveled strip affording inclined and abutting surfaces for the a usting-strips 17. The strips 46 and 47 may be resilient, consisting of hollow -"or elastic material. Furthermore, the adjusting- strips 17 and 47 may, if desired, be outwardly bowed intermediate their ends to insure the outward pressure "gral with the guides h 13,- -obviou sly they thereof between the thrust-links, as well as at points coincident with the ends of the latter.
In Fig. 1 I have shown a further feature of improvement consisting of a novel joint between the vertical and transverse side wall members of the stile and bar, respectively, at the corners of the sash, the same consisting of a dovetailed projection 10* fitting a correspondingly shaped notch 11 in the adjacent edge of the sidewall of the stile, the two being preferably welded together. The leading advantages of this construction reside in the fact that it not only affords a flush outer surface to the entire sash, but also avoids double thickness of metal and increases the strength.
