vented certain new and usei'ul Improvements 1n Windows, of which the following is a specilication. l

This invention relates to a window or door of the multifold type, being particularly concerned withthe mountings for the individual'window or door sections, and the means by which such sections are guided in their movements.

It is to be noted that the present improvementv is applicable to windowsv or doors composed ot' two or'more sections arranged to be folded upon each other 'for the purpose of aii'ording a wideV passage. Iny eX- plaining our invention reference will be made throughout the specification and drawings to a windowV constructiononly,

'although it should be borne in mind that y'substantially no modications are required in order thatthe same invention vmay be adapted for use with folding doors.

The present window construction has for its objects numerous purposes; itrissimple and inexpensive to build and install; it positively guides and securely holds the window sections against accidental dis-` placement; itpermits 'the window to be opened or closed without `binding' Iof Ythe parts and without undue frictionglit presents a `wide clearance when opened, without proyecting the window sections 1nwardly or outwardly tofany considerable eX- 'tentg' and itk provides a construction which isadaptable to two or more window sections,

as may be required. lThese and othery objects are attained bythe' present invention, as willfmore fullyhereinaiter appear from the specification and and from the accompanying drawings, 1n which Figure 1 is a View inelevaton Showing, in dosedp'ostmn a multiplerwindow consisty ing of `four saslies; n Y

The window of our invention is shown comprehensively in Fig. 1, and may consist of a plurality of sections orsashes, say tour kin number, which are designated as A, B, C, and D. These sashes are arranged within a suitable frame 14, having a sill 15, side vjambs 16, anda head` 17. Each of the' window sashes isy constructed substantially alike, with stiles 18 and top and 'bottom rails 19 and 2O,A respectively. Hinges 21 ,serve to connect together the window sashes and to permit the folding action which will presently be described. XVe `have also shown handles). which preferably should be inset "or countersunlrso as notk to 4project appr'ef.

Sash D, hoi'vever, is supported at its upper 'and lower ends by means of supports resembling those provided for sash B, but differingl in this respect: The lower support consists ofaplate '56 fixedly secured to the lower rail of the window and having an upturned end portion 5T which maybe inset and secured in the manner shown (see Fig. 10) rhis plate hasno sliding motion whatever, but in other respects is similar to the plate provided for. section "B,'in thatiit carries a ball 40 which travels within the same grooved plate 41 as does the ball in the plate 36. Likewise the support secured to the upper rail of the sash D consists of a plate 58 tixedly secured thereto, and carrying a pin and roller and 52 respectively, which lat` ter engages with the same guide rail 54 as does the roller on the slidable plate 47.

As appears best in Figs. 2 and 8, the outer edges of the stiles of each of the sashes may be provided with a groove 59 or a tongue 60 arranged to coperate, when alined, for the purpose of making a tight joint between the sashes. Likewise spring moldings 61 may be arranged upon the amb of the frame to be engaged by the sashes D and A when the window is closed. Upon the sill and head of the frame stops 62 may also be arranged so as to conine the swinging movements of the window sashes t0 an outward direction, or, if preferred, may be so arranged as to confine such movements to an inward direction. By such means as these, the spaces around the window edges are covered andprotected against the entrance of rain, wind, etc.

n Figs. 11 and 12, we have shown two possible positions for the window sashes. ln these positions, the window is not entirely but only partially open. As appears in Fig. 11, the sashes A and B remain in normally closed position, while the sashes C and D are swung `outwardly to open up substantially one-half of the window sash. ln Fig. 12, the sashes A and B alone have been outwardly swung, while the sashes C and D have been made to slide into the position shown. The amount of clearance adorded by the window, when in either of the positions shown in Figs. 11 and 12, is substantially the same. In order to fully realize the advantages of your invention, the sashes at the window extremities shouldbe slightly wider than the intermediate sashes. The dierence in width would be represented approximately by the thickness of the window sash, plus the clearance space between two sashes when folded into parallel relation. For instance, if the sash is l in thickness and the clearance between the sasheswhen folded together amounts to fg, then the outside sashes should be L15-,15" wider than the remaining sashes. The reason for this is readily apparent by an inspection of Figs.

fl-l yand 12, where two sashes of unequal l'are shown in 'this ligure. During closing ofthe Window, the sashes are alined, at which time a bumper block 64 secured to the sash C engages with the rounded edge G3 of the slide plate to force the same back into the guideway.

It will be noted that the present window requires for its construction a relatively few parts, some of which are interchangeable. The window may readily be installed by cutting the edges of the rails and stiles to receive the guide-ways, etc., and arranging upon the window frame the other parts which form the mountings for the window. It should be observed that the window sashes need not be mortised for the reception of any of these parts. T he number of window sashes to which our invention is applicable may vary from two up, it being necessary merely to duplicate the mountings for each pair of sashes added.

In operation it will be found that the sashes of the present window may be moved easily without any binding. This is because of the manner in which the sashes are secured to the window frame and to each other. At least one half of the sashes are independently supported and are provided with anti-friction members to permit of an easy sliding action. For these reasons the opening and closing operations may be readily eiiected. The present window construction is especially advantageous in that the sashes are connected directly to each other without the intervention of mullions which obstruct light and air. Our window, when fully opened, affords a clearance substantially equal to the entire width of the frame, the only obstruction remaining being that caused by the aggregate thicknesses of they several sashes.

We claim:

1. A multifolding window comprising: a frame; a plurality of sashes, not less than four, pivotally connected together; and connections between certain of the sashes and opposite sides of the frame*those with one end sash being pivotal only, those with the other end sash being pivotal and sliding, and those intermediate being pivotal and slidingy and eXtensible, all of the connections with the frame being situated in a single plane lying substantially midway between the inner and outer faces of the sashes when in closed position, substantially as described.
