Claims.

This invention relates to windows of the double hung or sliding type .in which the sash are pivoted so that they may be swung inwardly .as for cleaning or the like.

=5` The objects of this invention are to provide an improved window which may be economically manufactured and which will be particularly durable and convenient in operation; to provide a double hung window with means for pivoting the sash and means for counter-balancing the `same whereby the sash may be held in various vertical or tipped positions; to provide a window of the character indicated with novel stops or guides for facilitating or controlling the movements of the upper and lower sash; and to provide such further improvements in construcline 5 5 of Figure 1;

Figure 6 is a sectional view taken on the line 6 6 of Figure 5; and Figure 1 is a sectional view taken on the line 1 1 of Figure 6.

A window frame or easement I Il is provided with sides o-r stiles II, trim I2, stool or sill I3 and top I4. The lower sash I5 is provided with pivots I 5 adjacent to the lower edge for pivoting the same to slides or supporting members I1 which preferably extend upwardly to approximately the top of the sash and which are formed to make close contact with the sides thereof. The upper edge of `the sash may be fastened or locked to the slides I1 by means' of slidable catches I8 which may be moved outwardly, as

shown in Figures 4 and 7, to engage with notches or recesses I9 in the slides. Links 20 have their lower ends pivoted at 2| to the sides of the sash a short distance above the pivots I6 and when in y normal position extend upwardly along the sides of the sash as shown particularly in Figures 6 and '1. The upper ends of the links have pins or trunnions 22 which extend outwardly through slots 23 in the slides I1. These trunnions engage with channel-shaped supports or bearings 2li which iit closely in the slides I1 and are adapted to move longitudinally of .the same. The bearings 24 are secured to the lower ends of the counterweight ribbons or cords 25 which are connected with any suitable counterweig'hts or spring balance devices (not shown), such as are 5 commonly used for this purpose.

The slides or .supporting members I1 operate in grooves 26 in the frame, these grooves being conveniently formed by means of auxiliary stile strips 21 and 28. The lower sash is adapted to 10 swing between the strips 28 and the side rails 29 of the sash are recessed as shown at 30 to allow for the clearance for the slides I1 and the links 20.

Combined stop and guide members 3| are provided on the stiles or sides of the frame as shown 15 in Figure 1, these stops being arranged at a short distance above the top of the lower sash when it is in closed position and being adapted to register with the side rails of the sash to prevent outward movement of the same when the 20 sash is moved upwardly. Two pawls or detents 32 are pivoted `at 33 to the slides I1 at a short distance from the upper ends thereof. These pawls are preferably actuated by gravity and Y are limited in their movements by stop pins 34 25 and 35.

When the lower sash is locked or fastened to the slides I1 by means of the catches I8, it may be moved up and down as an ordinary double hung window. Ii? the catches I 8 are not fastened, the stops 3l will serve as guides to prevent the sash from swinging outwardly on its pivots.

When the lower sash is to be swung inwardly it is raised a short distance so as to clear the sill I2 and so that the upper edge will pass under the stops 3I. The initial outward movement of the sash tends to-raise the slides I1 until the pawls or detents 32 engage witlf'the stops 3l thus preventing further movement oi the slides. As the sash is swung downwardly, as indicated in Figure 3, the links 20 swing out and pulldown against the tension of the counterweight strips-25. The trunnions 22 are guided in the slots 23 in this movement and the parts are preferably so proportioned that the sash 4 will be held. in any adjusted position. 'Ihe downward swinging movement of the sash is stopped when the trunnions engage with the lower ends of the slots, thus preventing further movement of the links. When the sash is swung 5 to normal position the pawls 32 are swung inwardly so that they will not engage with the Astops 3| and they are concealed and held in retracted position by the sash.

The top sash 36 slides between the stile pieces 55 21 and is guided by the frame members 31 and parting strips 38. The parting strips stop just below the lower edge of the sash when it is in raised position so that the top of the sash will clear the same when the sash is swung inwardly. The top sash is supported in a manner similar to the bottom sash, being provided with pivots 39 which engage with channel shaped slides 40 which slide in recesses 4l in the stile pieces 21. Guide brackets or angles 42 are secured to the rear frame members 31 and serve to hold the slides 4D in their grooves when the frame is swung inwardly and similar guides 42a are provided for the slides l1. Links 43 have their lower ends pivoted at 44 to the sides of the sash and their upper ends are provided with trunnions or pins 45 which extend through slots 46 in the channels or slides 4D. The trunnions or pins 45 engage with channel shaped bearings 41 which slide in the channels 40 and which are connected to the lower ends'ofV the counter-weight cords or strips 48 which pass up over pulleys 49 and connect with any suitable counter-balance devices.

The slides 45 are provided'with pawls or detents 5U which are pivoted thereto at 5l Vat a suitable distance from the tops of the channels. These pawls are preferably arranged so that they will normally swing inwardly by gravity and their swinging movement is limited by pins 52 and 53. These pawls are adapted to engage at times with the lower ends of the parting strips 38 as shown in Figure 3. The side rails of the sash are grooved or recessed as shown at 54 to provide clearance for-the links 43 and the pawls 50.

When the upper sash is to be swung inwardly, the lower sash is rst swung in to provide room therefor as shown in Figure 3. The upper sash is then slid downwardly until the top edge will clear the parting rails 38 as shown in full lines in said iigure. Thereupon the window is raised somewhat as indicated by the arrows X until the pivoted edge is above the surface of the lower sash. The top sash may then be swung inwardly on its pivots, the upward movement of the slides 40 being prevented by the pawls 5B which swing out and engage with the lower ends of the parting rails 38. The continued swinging movement of the sash tends to pull the linksdown against the tension of the counter-balance members so that the sash is balanced in all positions. The downward movement is stopped when the trunnions 45 engage with the lower ends of the slots 46. When the upper sash is again swung back to normal position it will swing the pawls 5B back to retarded position so` that the sash will again be free to move up and down in its grooves in the usual manner. AWhen both of the windows are closed they may be locked by means of a catch 55 as shown in Figure 1, and other attachments such as commonly used for windows of this kind may be provided.

While I have shown and described a window provided with two sashes it is apparent that certain features of the invention may be utilized for a window having a single sash or a plurality of sashes and it is also apparent that changes may be made in the details of construction or arrangements of the parts in orderto adapt the same for dilerent installations and therefore I do not wish to be limited to the construction herein shown and-described except as speciiled in the following claims, in which I claim:
