Serial No. 199,094.

To all whom it may concern:

Be it known that we, WILLIAM A. ScnonN- ING and Josnrn PAoHYNsKr, both citizens of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Mountings for Folding WVindows and the like, of which the following is a specification.

This invention relates to certain mountings for windows of the multifold type, such as open up passages by a sliding and folding movement,. an example of which is shown in our Patent No. 1,245,0at2, issued October 30, 1917, of which this is a divisional application.

At the outset we 'wish it noted that the mountings which are herein disclosed are applicable to windows, doors, or like parts, composed of two or more sections arranged to be folded upon each other. For purposes of convenience in description, reference will be made throughout the specification to windows, in explaining the present mountings, although, as before stated, their use may be extended to doors or'other folding sections of similar character.

The mountings of our present invention are advantageous in that (1) they are sim-, ple and inexpensive to construct and install; (2) they positively guide and securely hold the window sections againstv accidental dis placement; they permit the window to be opened or closed without binding of the parts, and without undue friction; l) they present a wide clearance when open without projecting the window sections inwardly or outwardly to any considerable extent; and (5) they provide a construction which is adapted to two or more window sections as may be required. These as well as other objects are attained by the improved devices herein described, as will more fully hereinafter appear from the specification and claims, and from the accompanying drawings, in which:

Figure 1 is a horizontal section through a four-sash window of the multifold type, (the full lines indicating closed position, and the dotted lines partially open position), such as is adapted to be operated with the mountings of our invention;

Fig. 2 is an enl'argedsectional detail of the upper and lower roller mountings for one of the intermediate window sashes;

Fig. 3 is a sectional view similar to Fig. 2,

the sash being represented as in transverse relation to the window frame;

Fig. at is a sectional View similar to Fig. 3 of the roller mountings forthe sliding end window sash;

Fig. 5 is a detail in elevation showing the upper and lower mountings for the pivoted end window sash;

Fig. 6 is a detail, partly in section, showing the upper and lower mountings for one of the intermediate sashes which is represented as in closed position;

Fig. 7 is a detail, in plan, showingthe upper mounting appearing in Fig. 6; the adjoining sash being in angular relation to the sash on which the mounting is carried;

Fig. 8 is a detail of the upper mounting shown in Fig. 5, taken transversely of the head of the window frame;

Figs. 9 and 10 are views of the cooperating bearing plates for the upper and lower mountings, respectively, of Fig. 5; and

Fig. 11 is a plan view of the upper mountings shown in Fig. 5.

The mountings of our invention are particularly suited for use with windows of the kind illustrated in Fig. 1, consisting of a plurality of pivotally connected sashes, say, four in number, designated, respectively, as A, B, C, and D. Preferably the sashes are arranged within a suitable frame which may comprise such parts as a sill 15, side jambs 16 and a head .17. The sashes are constructed substantially alike, and, in the case of windows are formed with stiles 18 and with top and bottom rails 19 and 20 respectively. Hinges 21 serve to interconnect the window sashes and to permit of the folding movements which they are designed to execute. If desired, suitable locks 22 for holding the window sashes closed may be secured to the sill 15 in position to engage with the window sashes, as appears best in Fig. 1.

The sash A is fixedly hinged to one side of the frame, and to permit of swinging movements either inwardly or outwardly, according as the stops are located, and for economy in space as well, the pivotal mountings are secured to'the upper and lower rails of the sash in position to engage with hearing elementsmounted, respectively, on the frame head and sill. These mountings are best illustrated in Figs. 5 and 8 to 11 inclusive. The lower mounting consists of a member'23 having a tongue 24 and a head 25, the member as a whole being recessed tongue 24 and below the bottom edge of the sash rail as well, this boss being adapted to rest upon abearing plate 29 (see Fig. 10) suitably secured to the sill. A pin 30 is mounted in the head and is extended downwardly beyond the boss to enter ahole 31 formed in the bearing or journal plate 29. By this means the bottom end of the sash is pivoted upon the sill, being free to swing either inwardly or outwardly unless otherwise prevented, and at the same time it, is

maintained clear of thesill so as to confine friction, due to'swinging, to the engaging surfaces of the boss and bearing plate.

The upper pivotal mounting for the sash A is similar to that described, consisting of a member 32 shaped to provide a tongue 33 and a rounded head 34, the whole being recessed within the upper rail of the sash, and suitably secured by screws 35. A pin 36 is mounted in the head 34 and is projected upwardly therefrom through a hole'3. in a top bearing plate 38. The top bearing plate, best shown in Fig. 9, is preferably elongated and is secured to the frame head 17 transversely thereof at a point somewhat above the upper side of'the member 32 so as to provide a clearance therebetween. The pin36 extends out from the head 34 somewhat farther than does the pin 30 from the head 25 for reasons which will shortly appear. A slot or recess 39 is formed transversely of the frame head 17 in line with the pivotal'mountings for the sash. A, and for a width slightly greater than the width of the sash, enabling the sash when swung into transverse position to be rais d a distance equal to the depth of this recess; It is manifest, of course, that this upward movement of the sash into the recess 39 will lift the pin 30 of the lower pivotal mounting from its coiiperating bearing plate 29, and when so disengaged the lower end of the sash may be laterally shifted until the sill is cleared, whereupon the window can be lowered so as to disengage the upper pivotal pin 36 from the top plate 38 for the purpose of removing the sash from the frame. By a reversal of the movements described, the sash may, of course, be set into the frame, and there maintained securely within its pivotal mountings, the weight of the sash causing'it to rest upon the'f lower bearing plate where both provided which shall assist in the move-- ments of the sashes, only one of whichsash A-is fixedly pivoted on the frame. The supports or mountings for each sash are located in the center line of the windowthat is, midway between its inner and outer faces, and inline with the pivotal mountings'of sash -A.- The, mountings for sashes B, C, and D are of the samegeneral char-. acter as those'disclosed in our patent referred to,'No. 1,245,042, andin a four-sash window, such as we have illustrated by way of example, are situated, one set in the line ofjuncture between sashes B and C, and the other set at the free end of sash D. The mountings at the juncture of sashes B and C permit of pivotal, sliding,,- and extension movements, while the mountings on sash D permit of pivotal and sliding movements only. In these respects, they are to be distinguished from the mountings for sash A, which are pivotal only,

The mountings situated at the juncture of sashes B and C, best represented in Figs. 2, 3, 6, and 7, consists of upper and lower parts, the latter of which comprises a 'U- shaped guideway 40 recessed within the lower rail of the sash B, flanges 41 being provided to hold within the guideway a slide plate 42, The slide plate for purposes of strength and lightness is preferably formed with a body or web 43 on the sides of which are flanges 44 disposed adjacent to the inner'sides of the guideway 40 and its flanges 43. The sliding limits of the plate 42 are determined by a slot 45 formed in the guideway within which slot is project ed theend of a pin 46 threaded into-an opening 47 in the slide plate 42. In the construction shown two such openings 47 are provided to allow an adjustment in the sliding range of the plate 42, if this should be desired, the number of such adjustments, of course, being determined according to the number of openings 47 provided. Y The end of the slide plate is provided with a rounded head 48 within which is retained a revoluble ball 49 arranged to travel within a rooved plate 50 suitably mountedon the sill. The foregoing description should make in consequence of which the plate 42 will be extended longitudinally of the sash by sliding limits of the plate within 'theguideway. At its extremity the slide plate is formed with a rounded head 56 forming a mounting for a pin 57 secured in place in any convenient manner. Upon the pin 57 is mounted a roller 58 formed with an annular peripheral groove 59 and with an annular recess 60 at its upper end. A retaining head'6lis provided on the pin 57 being- 1 capable of entering the recess 60, whenever required, to permit of relative shifting movements between the roller and the pin 57. A guide rail 62 is extended horizontally 1 across the window frame in position to engage the grooved portion of the-roller 58 so as to hold the same on one side in a fixed line of travel. On its other side a stop 63 is arranged in engaging relation with the roller, thus cooperating with the rail 62 to provide, in effect, an inverted U shaped guideway within which the roller may travel.

In connection with the upper and lower mountings for the sash B, certain co6perating elements are provided on the sash C, these being best illustrated in Figs. 6 and 7. These elements are in all substantial respects identical, so that a description of only one is necessary, The lower element, shown best in Fig. 7, consists of a late 64 suitably mounted in operative position on the end of the sash C having at its end adjacent the sash B a curved wall 65 conforming in a measure at least to the-rounded end of' the' head 48 or the roller When the sashes are unfolded to close the window, this wall 65 acts as a bumper to engage with the ex tended head 48 and roller. 58 to force the same back into retracted position within their respective guideways. I

The sash C which is hinged at one sideto the sash B and at the other side to the sash D is adequately supported by the means already described. Upper and lower mountings for sash D are also provided, which resemble the mounting for sash B in many particulars. As appears best in Fig.4, the lower mounting for sash D comprises a member 66 shaped to provide a tongue 67 and a rounded head 68, the whole being suitably secured to and recessed within the lower end of the sash. Within the head is mounted a ball-69-adapted to travel within the grooved plate 50. The complementary mounting for sashD' at its upper end con sists of a member 70 having a tongue 71 and a rounded head TQcarrying' a pin 73 on which is mounted a roller 7% formed and" mounted similarly to the roller described in connection with Fig. 3. A groove 75 formed annularly of the roller is adapted to receive the guide rail 62', and an annular recess 7 6 formed in the upper end of the roller enables a head 77 on the end of the pin 7 3 to enter the roller for 'a slight distance,

thereby permitting a limited shifting move ment of the roller upon the pin. The mountings just described in connection with sash D resemble those for sash'B, with the exception that they are not extensible; they] are designed merely to permit of slldmg and swinging movements of the sash D as re:

qui-red for purposes of opening the \vin'do'w.

It will be noted that the mountings of our invention consist of relatively few parts, and that the component elements of each mounting may be handled as a unit during installation. The mountings for the pivot ed end sash and the sliding end sash would probably be used on any window consisting of two or more sashes, while the mountings for the intermediate sashes would be duplicated as many times as required for sup porting the intermediate sashes. "These mountings, as previously explained,-lie in the center line of the window and are wholly invisible from either side. The windows are thus enabled to swing either inwardly or outwardly according as desired, the only requirement being that the stops on the head and the sill be properly located. In use, it will be found that the present mountings guide the sashes accurately in their sliding and swinging movements, eliminate bind-- ing and undue friction, and afford adequate support for the sashes in their various posi-- tions.
