SLIDING AND SWINGING SASI-I.

Speccaton of Letters Patent.

Patented Oct. 3i, 1916.

Application led August 12, 1915. Serial No. 45,107.

To all whom t may concern:

Be it known that I, PETER J. McAvnY, a citizen of the United States, and a resident of the city` of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sliding and SwingingSashes; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being hadtothe accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to an improved type of window construction wherein sliding sashes are mounted in a frame and each of said sashes is provided with an auxiliary glass sash which is pivotally mounted,where by the glass sash may be rotated in the main sash into an open position or reversed there in if so desired to facilitate cleaning thereof.

It is an Object therefore of this invention to construct animproved type of window wherein sliding sashes are provided operating in the usual and ordinary manner for adjustment, said sashes being equipped with auxiliary glass sashes pivotally mounted and adapted to be adjusted therein to reverse the pane of glass in the sliding sash to clean or open the same.

It is also an object of this 'invention to provide a window construction wherein main sliding sashes are mounted in a window frame, each of said sashes being provided With an auxiliary glass sash pivotally mounted therein for adjustment, and with means operated by a suitable key to lock said glass sashes in the main sliding sashes.

It is also an object of this invention to provide a window construction wherein sliding sashes are mounted in a window frame, and mounted in each of said sashes are auxiliary glass sasheshaving pivotal connection with said sliding sashes adapted to be locked tightly and sealed therein or released for adjustment and reversal by means of suitable key' operated mechanisms inclosed within` the rails of the sliding sash and concealed from view.

It is furthermore an important object of this invention to construct an improved type of window wherein rotatable glass sashes are mounted within the usual sliding sashes of the window frame to ypermit complete reversal of the glass sash within the sliding sash, and with cam controlled key of Fig. l, showing the lower sash of the '1 window. Fig is a section taken on line 3-3 of Fig. l, with parts in elevation. Fig. et is a fragmentary sectional view taken on line 4.-4 of Fig. 2. Fig. 5 is a detail section taken on line 5--5 of Fig. et. Fig.V 6

is a detail section taken on line 6-6 of Fig. 5. Fig. 7 is a fragmentary top plan view of the lower' rail of the lower sash, with the glass sash omitted. Fig. 8 is a detail section taken on line 8&8 of Fig. t. Fig. 9 is a detail section taken on line 9 9 of Fig. 4f.

As shown in the drawings, the window frame is denoted as a whole by the reference numeral l, of which the sill thereof is designated by the reference numeral 2, and mounted inv said window frame is a main upper sash` 3, and a main lower sash 4, which are substantially identical in construction.

plementary glass sashes, that in the upper sash being denotedby the reference numeral 5, and carrying a pane of glass 6, and that inthe lower sash 4, designated by the reference .numeral 7, and carrying a pane of Mounted in each of said main .l sliding sashes 3 and 4;,are auxiliary or sup-yy glass 8. 1 Said respective main and auxiliary f sashes may be constructed of any suitable material., either wood or metal, as desired, and inasmuch as the construction and operation of each of the auxiliary glass carrying sashes is identical withreference to its sliding sash, a description of one will suflice. For this purpose the upper and lower rails of each of said sashes 3 and 4, are recessed or cored out, as clearly shown in Fig. 2,

and in each sash mounted in the recessed in therecessed portion of the lower rail of y'.-

each sash is a horizontal trough shaped member l0, which, however, is slidable vertically in said rail. The upper rail of the auxiliary sash 7, isk cored out at its middle, as indicated by the reference numeral 11, and inserted therein is a central pivot bolt 12, which is threaded tightly into Said trough member 9. A plate 13, is secured over the cored out portion of said auxiliary sash 7, and, as clearly shown in Fig. y2, the sash 7 has a sliding movement away from the trough member 9, limited in its downward movement therefrom by the head of said bolt 12. Similarly secured in the lower slidable trough member 10, is a centrally mountedk pivot ybolt 14, which engages loosely into a cored out recess 15, in the lower rail of the auxiliarysash member 7, said cored out portion being covered by a plate 16, provided for the purpose.

The loose pivotal connection thus pro* vided for the auxiliary sash 7, on said upper and lower bolts 12 and 14, respectively, permits the sash to be completely reversed into the main sliding sash 4, to fit snugly therein, the looseness of said pivot bolts permitting any inaccuracies of construction in this respect to be compensated for.

The manner in which the auxiliary `adjustable sashes are constructed and mounted in the main sashes is of particular Vnote. Reference to Fig. G will disclose thatthe end surfaces of the stiles of the auxiliary Sashes are slightly curved, as indicated by the reference numeral 17, and the inner end surfaces of the main sash are correspondingly curved on a radius equal to the dis tance to the central pivot bolts 12 and 14, so that a snug fit of the auxiliary sash into the main sash when in normal. or reversed position is assured.

Another feature of construction to which I desire to call attention is that in both the upper and lower sashes 8 and 4, the slightly curved inner surfaces of the stile members against which the auxiliary sashes 5 and 7, t, are convergent a very small amount toward the upper end, and the stile mem-y bers of the respective auxiliary sashes 5 and 7, are similarly constructed in conver gent relation. The amount of convergence, however, is very small, and is shown inv F ig. 1 of the drawings somewhat exaggerated, but suliicient so that when said aux` iliary sashes 5 and 7, are moved upwardly the small amount required to tit the same tightly within the sliding sashes 3 and 4, they are wedgingly engaged therewith.

llfhen the lower trough member l0, is thrust upwardly, the auxiliary sash 7, seating therein, is thrust upwardly tightly within the upper trough member 9, so that said auxiliary sash is thus held securely in the main sliding sash Then the lower trough member 10, is released and moved downwardly, the auxiliary sash 7, moves downwardly until limited by the head of the upper pintle bolt 12, the sash of course moving clear of the trough member 9, and similarly at the lower rail of said auxiliary sash 7, the trough member 10, moves downwardly and away, so that the auxiliary sash can then be swung and reversed in the main sash if so desired.

Mechanisms for operating the lower trough member 10, to effect these operations, consist of a central actuating bar 18, having a central cut-away slot or aperture 18, therein, which fits over a short rotatable arm or cam 20, rigidly secured upon a bolt 21, which is mounted transversely in the lower rail of the sash 4, and has a squared head 22, to receive fitted thereover a key for -rotating the same and said cam therewith. At each of its ends, said bar 18, is linked to auxiliary actuating bars '19, and connected at the pivot connection between said bar 18, and bars 19, and also at the extreme outer ends of said bars 19, are cams 23, pivoted uponv fixed pintles 24, secured transversely through the cored out portion of the lower rail of the sash 4. Each of said cams 23, consists of two parts similar in construction, as clearly. shown in Fig. 5, and each part is provided with a curved slot 25, en-

gaged within whichis a pin 26, having integral therewith an extension 27, which projects upwardly from between the two parts of the cam through an aperture provided in the trough member 10r and has inserted through its upper end a split retaining pin 28. The stilesfof each of said 4sashes 8 and 4, as clearly shown in Figs. 4 and 8, are provided with tongues 29, for engagement with the end of the lower trough member 10, which is slotted for the purpose, to assist in guiding the same in its movement.

rPhe operation is as follows: If it is desired to reverse the pane of glass in either one of the sliding sa'shes 3 or 4, as the case may be, when the 'sashes are in the closed position illustrated in Fig. 1, 'a suitable key is inserted over the squared end 22, of the bolt in the bottom rail of the sash and. turned in a co'unterclockwise direction, thus throwing the cam 20, shownin Fig. 4 to the left end sliding the bar 18, therewith. This sliding movement of they bar 18, imparts Ya corresponding movement, ofcourse, to thebars 19, and consequently causes a clockwise rotation of the four :cams 23, which hold the trough member 10, thrust upwardly, thus drawing the same downwardly, due to the engagement in said cams* of the pins 26, and 'this allows the auxiliary sash 5 or 7, as the case may be, to drop downwardly a small amount suflicient at least to disengage the same from the upper trough member `9, shown in Fig. 2. The downward movement of the `auxiliary sash is limited by the head of the bolt 12, engaged therewith, fand of course, due to the il ment by the heads of said pintles: Said aux'.

fact that the trough member 10, drops downwardly to a greater distance than the auxiliary sash member so as to be out of engagement therewith, the auxiliary sash member and pane of glass mounted therein may then be rotated about the centrally disposed pivot bolts 12 and 14, and 4if desired completely reversed in the sliding sash.

Similarly when said key tits over the squared end 22, of the actuating head or bolt is turned in a clockwise direction, the slide bar 18, and bars 19, are moved to the right, thus drawing the cams 23, into a position to elevate the lower trough member l0, which in turn elevates the auxiliary sash which is thus thrust upwardly against the upper trough member 9, in sealing locked relation therewith so as to be rigid in the sliding sash.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

l. In a window construction of the class described, a main sash, a glass-carrying auxiliary sash mounted in said main sash, pintle bolts mounted centrally at opposite sides of said main sash and having projectd ing headed ends, said auxiliary sash being engaged by said headed ends and shiftable thereon and limited in said shifting moveiliary sash being pivoted to rotate upon said pintles, and means for shifting said auxiliary sash on said pintles wedgingly to look the same in its closed position.

2. In a window construction of the class described, a main sash, a glass-carrying aux lllary sash mounted in said main sash, p1n

.tle bolts mounted centrally at the top and bottom of said main sash and having projecting headed ends, said auxiliary sash being engaged by said headedends and shiftable vertically thereon and limited in said shifting movement by the heads of said pintles, said auxiliary sash being pivoted to rotate upon said pintles, and means for shifting said auxiliary sash vertically on said pintles to lock the same in its closed position. y

3. In a window construction of the class described, a main sash, a trough member mounted in the upper rail of said main sash, another trough member adjustable in the lower rail of said sash, pintle bolts engaged in said trough members and having projecting headed ends, an auxiliary sash pivoted f5 of said trough members securely to loclr said 3l auxiliary sash in the main sash.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
