SPECIFICATION forming part yof Letters Patent No. 741,457, dated Octoberk 13, V1903. Application `filed December 3,1902. Serial No. 133,800. (No modal.)

To all whom t may concern:

Be it known that we, FRANZ J ULIUs CARL, a citizen of the United States, and HERMANN GUsTAv CARL, a subject of the'Emperor of Germany, both residing in the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Windows, of which the following is a speciiication.

This invention relates to the manner of han ging window-sashes in dwellingsand other buildings vand our obj ect therein has been to provide a practical construction whereby both the upper and lower sashes of the ordinary vertically-movable type may be also capable of swinging, and thusbe rendered accessible for cleaning the glass upon both its inner and its outerv sides without the use of step-ladders and without reaching out ofthe window or otherwise gaining access to the glass from the outside of the building, as is requisite with l the ordinary vertically-sliding sashes.

The nature of our improvement is fully set forth below and will be understood fromthe description thereof when considered in connection with the drawings, in which- Figure 1 is an elevation of a window embodying our invention. Fig. 2 is a section thereof on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1. Fig. 4 is a horizontal section showing a dou` ble window with the sashes all swung open. Fig. 5 is a section on the line 5 5 of Fig. 1.

Fig. 6 is a section on

line

6,6 ofFig. 1. Fig.y

7 is a partial elevation of one of the sashes. Figs. 8, 9, 10, and 11 are detail views of the hinges. Fig. 12 is a detail section of one 0 the antifriction-rollers. In the drawings, lrepresents the windowframe, and 16 is the upper sash, and 17 the lower sash. Both are provided with counter- `balance-weights, that of the upper sash being shown at 1S and thatof the lower one at 19,

the cords 50 passing over pulleys 20. But one weight is used with either sash in order that one side of each may be free to swing open without detaching any sash-cord. Each sash is also provided on one lside with hinging devices, as indicated. In the case of the upper sash sockets or Ieyes 21 and 22, each formed on the ends of

straps

23 and 24, are

i secured, respectively, to the top rail and the meeting-rail, as seen more particularly at Fig. 7, and the window-frame is provided with a pivot 25 near the center of the side rail of the frame adapted vto enter said socket 21 when the sashis lowered to its lowermost position, and a'second pivot 51 near the bottom y adapted to enter the socket 22 when the upper sash is in its lowest position; This construction permits the lowering of the sash and its being swung open while in the lowered position. Y

In the case of thelower sash sockets or eyes 27 and 2S are attached near the top and bottom, respectively, of one of the side rails of the sash, and the side of the window-frame is provided with

corresponding pivots

29 and 3 0,

each adapted to enter one of said sockets l when the sash is in its normal plane and to permit it to swing upon them. VThe upper socket is adapted to set down overl the pivot l 29; but the socket 28 is fashioned differently, having an open slot 31 formed in its side and extending from top to bottom in order that when the sash is raised the socket 28 may pass entirely by pivot 29 without interference,

the slot giving rooIn for the leaf 32, supporting the pivot, as one moves past the other, as will be understood from Fig. 6.

Upon the hinged side each sash is formed with an ogee curve, (seen at 33 in Figs. Sand 4,) with an overlapping shoulder34, and the side of the frame is correspondingly shaped. This form permits all necessary swinging of the sash, forms a tight joint with the sash when the latter is closed, and holds the sash iirmly against pressure from without. The weights and the hinges of each sash are located on the same side thereof, Nas the sash-cords supporting the weights freely permit all nec- IOO caused by the use of a single weight instead of the two commonly used, as they are located near the upper corners of the'sashes, where the friction is greatest.

The sashes may be locked together in the usual way by a sash-fastener 39, located centrally of the meeting-rails; but instead of relying upon the fastener as a means of locking the sash bolts or catches 40, operated by the key or handle 4l, may be applied to one or both sashes, the one applied to the upper sash being sunk into the wood, so as not to interfere with the sliding of the lower sash. The sill of the window is desirably hollowed out, as at 42, to catch any rain which may iind its way through the window. The upper rail of the upper sash and the lower rail oi' the lower sash are both fashioned7 as plainly shown in Fig. 2, in order that they may edectually eX- clude both cold and rain.

It will be noticed that the hinges of each sash are at the same side with its weight, so that we not only avoid any necessity of detaching the sash-cord when the sash is swung open, but avail of the flexibility ot the cord, which permits the swinging. It will also be noticed that the weight and hinges of each sash are upon a different side from the weight and hinges of the other sash, so that there need be no interference between them when swung open. The hinges used are all separable and are united and separated by the vertical movements of the sash, as will be understood from the description already given.

Vith the construction described the sashes are permitted to slide up and down with the same freedom as the ordinary sash, the lower sash can be swung inward without any preparatory change of position, and the upper sash can also be swung inward by first lowering it, so its hinge-sockets effect operative relations with pivots 25 and 5l.

The invention may also he applied to double windows, and I show at Fig. fl a section of such a window with all the sashes swung open. In the double window both the inner and outer windows correspond in construction and manner of hanging with the construction above set forth.

We claiml. The combination in a window of upper and lower sashes, both adapted to slide vertically and to swing inward f rom opposite sides when in their lower positions, and both provided with separable hinges, the parts of which are assembled when the sashes are in their lower positions.

2. The combination in a window of upper and lower sashes, both adapted to slide vertically and to swing inward from opposite sides when in their lower positions, and both supported by weights attached to them on their hinged sides only, the hinges upon which the sash swing being separable.

3. The combination in a window, of upper and lower sliding sashes, each supported at one side only by a sash-weight and each having an antifriction-roller at its unsupported side bearing on the window-frame, and the weight and the roller of one sash being at the opposite side of the window from the weight and roller of the other sash, substantially as speciiied.

4f. The combination in a window, of upper and lower sliding sashes, each supported at one side only by a sash-weight and provided with hinges at its supported side upon which it may swing when in its lowest position, and each also provided with the antifriction-roller at its unsupported side entering a groove in the window-frame, substantially as specified.

5. The window having upper and lower sash which slide and also swing inward on separable hinges when in their lower positions, the socket of one of the hinges being slotted to enable it to pass the stationary pivot of another hinge, substantially as specified.

6. rlhe combination in a window of an upper sash and a lower sash both sliding vertically and both swinging on separable hinges when in theirlower positions,the hinges ofthe upper sash being normally separated and those of the lower sash being normally complete, and its hinges being located at the opposite side of the window from the hinges of the upper sash, substantially as specified.
