I. will; not ldescribe thev connections between the 'shaft-L 4Q and theshaft42 .because they are exactly the shaft 32. This shaft 42 has a bearing in a bracket 44 depending from the top of the window casing.

All these gears have the same numbeil of teeth but an advantageous leverage is secured by having the gear 29 made with teeth of double length and causing the driving gear 2S to mesh with it at a greater distance from the center than the driven gear 36. Thus, the two shafts 32 and 42 will be rotated at the samerspeed, although this provides a sort of differential to transmit an excess of power caused by any undue resistance from one shaft to the other and equalize the strain.

The two shafts 32 and 4Q are provided with screw threads of opposite pitch but of course the same number of threads to the inch. Each of these is provided with a nut 45 adapted to be moved along the shaft by the rotation of the latter. Each nut is swiveled by a horizontal pin 46 to a bracket 47 of right angular construction to ht around the corner of the sash. The bracket constitutes half of a hinge and has a vertical.

pivot stud 48 at the outer end of the projecting part which, in turn, is pivoted to a right angle plate 49 constituting the other half of the hinge and secured around the corner of the sash 11. These two pivot studs 4S arer in vertical alignment and the two hinges thus formed necessarily operate together and equally. The casing and sash are recessed at 54 to receive the parts 47 and 48. The controlling arms 14 and 18 being constructed exactly alike and located in exactly corresponding positions also help to control the motion of the sash so that it will always move equally at top and bottom. The gear arrangement insures an equalization of strain between the top and bottom and therefore, even after long usage, the two operating mechanisms will continue to operate the sash equally at the top and bottom. Therefore the device is not likely to get strained at either place or to bind.

For the purpose of preventing undue strain on the parts when the window is start-- ing to open, I provide on the stationary part of the sash at the top and bottom a plate 50 having a projection provided with an upward guide 51 which is longitudinal with respect to the closed window and is intended to operate only while the crank handle 22 is being turned to take up any looseness of the gears before the sash begins to turn. It

, might be explained here that the first motion of this crank moves outwardly the two nuts `4.5 slightly before the sash can commence to turn. This action takes place during about a quarter of a turn of the crank and it might 1tend to swing the hinge member 47 and bind the parts if no guide were provided. Also in closing, a perfectly tight closure is difficult to secure at this point for the same reason. Therefore this short guide 51 projects upwardly at the bottom behind the hinge part 47 and insures longitudinal motion at the end of the closing and beginning of the opening motion. Therefore the motion of the nut 45 and its bracket 47 slightly to the left to the position shown in Fig. 2 from that in which it is up against the head of the hub 32 will not bind the sash but will release it. Also, it will be noticed that when the sash is closed the outer end of the sash comes up into perfectly closed position but the inner end has a tendency to move outwardly slightly. But during the last quarter turn of the crank 22 this guide 51 comes into action and firmly holds the inner end of the sash in tightly closed position. This construction is formed at the top and bottom and the same reference numerals are applied in both places.

In this way it will be seen that a construction is provided which is not unduly expensive but which will positively actuatc the shaft both at the top and the bottom, will positively close it at the pivot edge, keep it closed until the crank is turned, and prevent its moving outwardly at the beginning of the turning of the crank and binding. Furthermore, by the gear arrangement the strains at the top and bottom are equalized and therefore the wear is the same in both places. The window does not swing on alixed pivot but on a movable one so that it will move along the sash at the pivot end and the sash will be located part way between the two sides of the casing when it is open so that the window can be washed on both sides from the interior of the house.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the detailsv of construction herein shown and described but what I do claim is 1. In a. sash operating device, the combination with a casing and sash, of two screws located constantly in horizontal position at the top and bottom of the casing for simultaneously and equally moving the top and bottom of the inner edge of the sash away from the adjacent edge of the casing, means for actuating said screws, and means-acting directly on the top and bottom of the outer end of the sash for swinging it outwardly.

2. In a sash operating device, the combination with a window casing and sash, of a pair of arms one located above the top of the sash opening and the other below the bottom of the sash opening, both pivoted to the casing at points intermediate the inner and outer surfaces thereof and pivoted at their' outer ends respectively to the top and botto-1n of the sash at points adjacent to the inner edge thereof, a pair of hinges, one hinge member of each hinge being xedly mounted on t-he inner side of the sash at the top and bottom and extending around the edge of the sash and having a hinge pivot located along the edge of the sash, the other two hinge members being connected with the hinge pivots and having a part extending therefrom inwardly toward the inside of the casing and another part `at right angles thereto parallel with the front face of the casing, and means for sliding the latter along the casing parallel with the front surface thereof.

3. In a sash operating device, the combination with a window casing and sash, of means located at the tQp and bottom of the casing for simultaneously and equally moving the inner edge of the sash away from the adjacent edge of the casing and swinging the outer end of the sash outwardly, said means comprising an arm pivoted to the casing and to the sash a crank, a pair of right and left hand screws, one located at the top of the casing and the other at the bottom parallel with each other, a vertical shaft having gears at the top and bottom, gears on the horizontal screws meshing with the gears on the vert-ical shaft, and means for turning the vertical shaft from the crank.

4e. In a sash operating device, the combination with a window casing and sash, of an arm pivote'd to the casing and pivoted to the sash, a hinge comprising two members, one being ixedly mounted on the inner side of the sash and extending around the edge of the sa'sh and having a hinge pivot located along the edge of the sash, theother hinge member being `connected with the hinge pivot and having a part extending therefrom inwardly toward the inside of the casing and another part at yright angles thereto, and means for sliding the latter part along the casing parallel with the front surface thereof.

5. In a sash yoperating device, the combination with a casing and sash, of an arm pivoted to both for swinging the sash, a hinge having two members, one fixed to the edge of the sash and the other slidable along the casing, and having an offset at the end at which it is pivoted to the other hinge member on the edge of the sash, a nut swiveled to the sliding part of the hinge, and a screw passing through the nut for operating it.

6. In a sash operating device, the combination with a casing, a sash and an arm pivoted to both for swinging the sash, of a hinge having two members, one fixed to the edge of the sash and the other slidable along the casing, said members both having an offset at the end at which they are pivoted together by a pivot pin, a nut swiveled to the sliding part of the hinge, a screw passing through the nut for operating it, and a guide plate fixed on the side of the casing and having a hook projecting under the sliding member in certain positions thereof for preventing side play of the sliding member at the time when the sash is closed or nearly closed.

In testimony whereof have hereunto afixed my signature.

WILLIS E. PUTNAM.
