Application filed April 14, 1915. Serial No. 21,380.

To all whom it may concern Be it known that I, ARTHUR C. SoULE, a citizen of the United States, residing in the city and county of San Francisco, State of California, (Whose post-o ifice address is 226 Judah street,) have invented new and useful Improvements in Double-Sash-Window Mountings, of which the following is a specification.

This invention relates more particularly to mountings for supporting and controlling a plurality of sashes slidably pivoted in a Window frame.

Among the objects of this invention are to produce a mounting simple in construction easily installed and adjusted; that will give to the sash as nearly as may be, uniform support in its various adjustments and evolutions; that is architecturally and commercially attractive; that will permit the sashes to be reversed within the window opening; that Will allow the necessary individual operation of the sashes, while maintaining a combinative action between the several sashes in the frame so that they will not interfere with each other; that connects the several sashes together in such a manner that they contribute to the holding of each other in the desired adjusted positions; that is adaptable to various types of window frames.

Other objects and advantages will appear as the description progresses.

In the drawings accompanying and forming part of the present specification, to which like reference characters have been applied, a simple form of putting this invention into practice is shown. I do not wish to be understood as confining this invention to the disclosures made in said drawing and description, as many variations may be introduced, within the spirit of this invention, as defined in the claims succeeding the said description.

This invention includes the pivoting of the sashes on opposite sides, on pivots frictionally engaging grooves in the opposite sides of the window frame, to permit the swinging of the sashes in the Window frame for ventilation. The movement of the sashes is controlled by a system of levers interposed between the sashes, and between one or more of the sashes and the Window frame, to hold the sashes in any fixed position desired against Wind pressure or other shifting forces. The pivotal type of sash is hard to control in its various evolutions by the ordinary means, owing to the shifting balance of weight when the sash is moved from the closed or vertical plane, to the full or horizontal plane, and reversed or restored to the vertical plane, or returned to the closed position Without reversal. In the present invention the relative proportions and combina tive actions of the various levers are always in favor of the supporting and controlling mounting, as against the weight of the sash that is the load to be supported; and permit the control arms to be pivoted at or sufliciently near to the center of the sashes to allow them to be reversed Within the window opening, a very substantial advantage in window washing.

In the four sheets of drawings: Figure 1 is a side elevation of a window frame shown in cross-section, having two sashes pivotally operating therein and mounted in accordance with this invention, both sashes being shown in the open position, the mounting is indicated in its proper relative position as it would be attached to the near side of the window frame, if the latter Were not removed to better disclose the sashes and their mountings. Fig. 2 is a similar view showing the sashes approachin the reverse position within the window frame Fig. 3 is a view similar to Fig. 1 excepting that a modified form of support arm is indicated, the nethermost sash having the pivots in its lower end and the support arms pivoted above the sash. Fig. 4 is a similar view showing the upper sash in the reverse position. Fig. 5 is a side elevation similar to Fig. 1 illustrating a modified form of intermediate control mounting between the sashes and the sashes and the frame. Fig. 6 is a fragmentary enlarged detail of a portion of this modified mounting. Fig. 7 is a fragmentary detail partially in cross section illustrating the general construction of the sash pivotadapted to frictionally engage the window frame. Fig. 8 is an enlarged detail in plan from above showing the sash closed within the opening, illustrating the correlation of the various parts and particularly the curved weather strip adapted to render the window opening Weather proof when the sashes are closed.

In detail, the construction illustrated in the drawings includes the window framing composed of the sill 1, the stool 2, the side stiles 3, connected across the top by the lintel 4, the usual stops 5 and other weather proofing elements and finish. The side stiles 3 are provided with the grooves 6 on the opposite. sides of the frame to receive the sliding pivots of the sashes.

The upper and lower sashes illustrated are alike in construction, arrangement and operation, except as to their location in the upper and lower portions of the window frame respectively. They include the side stiles 8 joined by upper and lower rails in the usual manner. In the construction illustrated in Fig. 1 the opposite upper corners of the sashes are provided with resilient pivots. These pivots comprise the stems 9 having the friction shoes 10 riveted thereon. (See Fig. 7.) The stems 9 pass through the holes in the plates 11, fixed to opposite sides of the sash. The holes 10 are lined with the tubes12 crimped in the plates 11, the stems 9 sliding and pivoting freely in these tubes. The tension of the springs 13 expanding between the bottom of the holes and the ends of the stems 9 forces the friction shoes 10 into contact with the grooves 6 within which they slide.

In Figs. 1 and 2 the. lower sash is provided with the sliding pivots 10, in its opposite upper corncrs, these pivots frictionally engaging the grooves 6 as described, the friction being proportioned to support and control the weight of the sash, in connection with the support mounting. Between the upper and lower edges of the sash, preferably near the middle, the support arms 14 are pivoted at 15 to the sash and at 16 to the window frame, preferably in line with the groove 6, although these pivots 15 and 16 may be otherwise placed in their respective engagements with the frame and the sash. The length ofthe arms 14 is proportioned to permit the reversal of the lower sash within the opening, whereby said arms will perform the double function of supporting a large portion of the weight, and of controlling the operation of the sash. The upper sash is similarly pivoted in the frame, the construction and location of the pivots 10 in the upper and lower sashes being similar; therefore each sash is capable of the same evolutions within the window openings, within the limitations of their respective support mountings. The upper and lower sashes are connected together by the connecting arms 17 having their lower ends pivoted at 18 to the lower sash between the pivots 15 and the sliding pivots 10, and their upper ends pivoted at 19 to the upper sash preferably near the middle between the upper and loweredges. These locations of the pivots 18 and 19 vary with the size and other conditions of the respective sashes to which they are connected. This combination of the upper and lower sashes connected together and mounted in the frame includes a lower sash frictionally pivoted in the window frame and controlled-in its various evolutions by the supporting arms 14, cooperating with the sliding pivots 10 to hold the sash at any angle, with respect to the window frame, that it may be placed by the operator. The upper sash is slidably pivoted in the window frame in a manner similar to the lower sash, but is controlled in its evolutions by the connecting arms 17, connecting it to the lower sash and through it to the window frame making the evolution of the upper sash subservient to the operation of the lower sash, giving to the upper sash a wide range of adjustment ultimately modified or controlled by its connection with the lower sash. One object in thus connecting the two sashes is to prevent interference of one sash with the other in their various evolutions, so that the sashes can always be restored to the proper closed position with the minimum effort. The connection and mounting means between the lower sash and the frame is capable of a wide range of variations as broadly indicated in Figs. 3 and 5, that are merely suggestive without indicating the limit of modification. The second sash may be duplicated at will, within a single frame, by connecting superimposed sashes pivoted in the frame.

In Fig. 1 the upper edge of the lower sash is tapered as at 20 to fit within the groove 21 formed in the lower edge of the upper sash. The upper edge 22 of the upper sash fitting within the groove 23 in the lintel 4, and the lower edge 24 of lower sash engaging the sill 1; causing these sashes when in the vertical or closed position within the window frame, to form weather tight joints at all of these various points. Both sashes are locked when in the closed position by the. latch 25 engaging the keeper 26 fixed on the window frame. The interconnection of the two sashes as described effectually locks both sashes when either of them is locked within the window frame.

Fig. 2 shows the upper sash approaching ,the reverse position within the window frame. Attention is directed to the location of the upper sash in the reverse position, it being lowered to a convenient level for washing. The reversed lower sash is also in a convenient position for the same purpose. In Figs. 1 and 2 the connecting arms 17 are offset atthe ends so that they will clear the pivot stems 9 when the sash is in the vertical position either in the closed or in the reverse position; the same effect may be produced by extending the pivots on the plates projecting beyond the plane of the sash. This is an unnecessary refinement, and because of the additional cost can be very well omitted withoutinterfering with i 444c ni ig the proper workings of the parts that are influenced thereby.

Fig. 3 illustrates a modification of the structure, in that the sliding pivots 10 are located at the lower edge of the sash and the supporting arms 27 pivoted at 28 to the sash, are pivoted at 29 to the frame above the pivots of the sash, instead of below as in Fig. 1. The upper sash is connected by the connecting arms 30 pivoted at 31 and 32 to the upper and lower sashes respectively. The pivot 31 is located between the pivots 28 and the upper edge of the lower sash in the same relative position as in Fig. 1, except that it is not between the pivot 28 and the sliding pivot '10 of the sash as in Fig. 1. The results obtained in the two structures illustrated in Figs. 1, 2, 3, and 4 are practically the same, the mode of operation being slightly varied because of the pivotal variation of the two structures. The pivots 29 are connected to a plate 33 attachable to the frame. The pivots 16 may be similarly attached to the frame or attached in any other manner, either differently located or capable of adjustment, to permit perfect regulation in the operation of the sash that they control. The arms 14 support the sash from below and the arms 27 suspend it from above, the function being the same but the mode of operation differing accordingly.

Fig. 5 illustrates a further modification of the structure, illustrating a new element and a different mode of operation introduced in the intermediate mounting between the two sashes. The lower sash is supported by the supporting arm 34 pivoted at 35 to the frame and at 36 to the sash. The equivalent of the sliding shoe 10, is the elongated channel 37 slidable in the groove 6 in the same manner as the shoe 10. The lower sash operates as illustrated and described in connection with Fig. 1 the stems 9 being fixed in the channels 37. The upper sash is slidably pivoted at the upper edge as in Figs. 1, 2, 3 and 4, and is supported by the connecting arms 38 pivoted at 39 to the sash and extending downward and pivoted at 40 to the shoes 41 slidable in the groove 42 in the channels 37 The connecting arms 38 are controlled by the controlling arms 43 pivoted at 44 on pivots fixed in the channels 37, and at 45 to the connecting arms 38. The controlling arms 43 carry the weight supported by the arms 38 on opposite sides of the sash and limit the downward movement of the slide 41. When the angle of the upper sash is changed the slide 41 slides up or down within the channels 37 in accordance with the movement of the sash, exerting suflicient friction within the channel to hold the upper sash in the desired position in cooperation with the supporting arms 43. The pivot 44 for convenience is fixed in a plate 46 inserted within the groove 42 in the channel 37 having the lower end notched to straddle the stem 9 fixed in the channel 37 When thus placed the corners 47 of the inturned edges of the channels may be bent inward to hold the plates 46 securely within the groove of the channel, holding the pivots 44 a fixed distance from the stems 9 of the pivots upon which the lower sash is hung. This construction is intended more particularly for convenience in assembling the parts. The pivot 44 may obviously be attached directly to the channel 37 in the same relative position.

The structure illustrated in Fig. 5 is particularly adapted to the mounting of heavy sashes. The channel 37 presents more frictional contact within the groove than the shoe 10, to contribute the necessary supporting power for supporting the weight of the lower sash thereupon, plus the additional weight of the upper sash supported thereby. The additional friction of the shoe 41 within the groove of the channel 37 in addition to the supporting help of the arm 43 contributes the necessary additional friction and support to control the weight of the upper sash.

In casement windows in which the movement of the pivotal sashes are all horizontal instead of on the vertical plane, as illustrated, the sashes can be connected together as in Figs. 1, 2, 3, 4, and 5, but needless to say, the present supporting members 14, 27 and 34 become merely control members and need not be calculated to do more than merely control the evolution of the sashes, as they have no weight to support.

Fig. 8 illustrates a novel manner of rendering the lateral joint between the sashes and the frame weather proof and consists of the strip 48, extending from top to bottom of the window opening on both sides. It is secured to the side stiles 3 within a groove rabbeted therein between the lateral edges of the sash and the stiles 3, for the accommodation of the controlling arms when the sashes are in the closed position. The weather strips consist of thin strips of spring metal having one edge secured to the side stiles and the opposite edge curled upward into contact with the edges of the several sashes. The s ringiness of the weather strips exerts su cient frictional contact against the edges of the sashes to exclude cold, dust and other weather conditions. The curved shape of the strip causes it to glide smoothly in contact with the edges of the sashes.

Having thus described this invention, what 1 claim and desire to secure by Letters Patent 1. A window sash mounting comprisinga frame, a sash having one end slidably pivoted in said frame, the other end being free,
