DEVICE FOR OPERATING TRANSOMS AND CASEMENTS.

Specification of Letters Patent.

Patented Feb. 15, 1916.

Application filed November 19, 1914. Serial No. 872,877.

To all whom it may concern Be it known that I, OSCAR C. RIXSON, a

citizen of the United States, residing at the city of New York, in the borough of Manhattan and State of New York, have inventfor its primary object the provision of an operating mechanism of this character which is of a simple and compact constructionlending itself admirably for'use where it is desired to conceal such mechanism within the window frame 'or door casingi Other objects of the invention are to provide a mechanism which is positive 1n oper- .ation,-'capable of being readily and easily manipulated and by which the windows,

' transoms or the like are held in any desired position without the aid of latches or other fastening devices.

With these and other objects in view,

which will be obviousto one skilled in the art from the detailed description hereinafter to follow, my invention consists of the constructions and combinations which will be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a plan -view of a portion ofia window framehaving associated therewith one form, of my improved construction, the stool of the window frame being removed to more clearly show the operating mechanism; Fig. 2 is a vertical section through Fig. 1; Fig. 3 is an enlarged view of the operating mechanism, the same being shown apart from its connection with a winds-v.7; Fig. 4 is a -.vertical section through'a door casing showing my improved mechanism associated with a transom; and Fig. 5 is a vertical sectional view takenat right angles to Fig. 4.

Referring first to Figs. 1, 2 and 3, wherein there is shown the actuating mechanism associated with a window frame and casement of the usual type, 1 designates the sill of the window, 2 the apron ortrim, and 3 the stool which is spaced from the sill by means of a block 4 to leave a recess or chamber a which is adapted to receive the actuating mechanism as willbe hereinafter described.

A hinged window or casement 5, only a portion of which is shown, is of the usual type and is pivoted as at 6 to the window frame or casing 7. A stop 8, of the'ordinary construction may be secured to the inner portion of the window frame. As is shown, the window 5 is adapted to swing outwardly on its hinge 6, which is accomplished by means of the actuating mechanism which will now be described. Inset in the inner face of the bottom strip of thewindow sash is a plate 9, carrying an angularly pro ecting finger 10 which is substantially flush with the bottom of the sash, which finger projects into the chamber a when thewindow is closed, and carries at its outer, or-

free end a pivotally mounted roller or block 11 of fiber .or' any other, desired material, which is adapted to ride in a slot inthe bottom face of a tubular member 12, which is substantiallyrectangular in cross section.

The outer end of this member is closed by a cap :13 which will prevent the roller or pin 11 from leaving the slot, while the other end is forced; over the end of .a solid lever. 14 and forms a rigid continuation of the same. The lever 14 is pivoted as at 15, to a base plate 16, which is secured to the sill in the chamber a and rising from the base plate is a casing or'housing 17 into which. one arm of the lever extends, the -casing"being so shaped that it will not interfere with the movement of this lever to its fully openedi position as is shown in dotted lines. In the, interior of this housing is. screw or threaded shaft 18, one

mounted ina recess in a plug 19, which is threaded into a suitably shaped aperture reduced diameter and passes through a suitable bearing in a boss '20. Steel washers 21 and 22 preferably are provided at each end positioned a end of which is of reduced diameter, and is rotatably of the threadedportionofthe screw to take up its end thrust, the length of screw between the washers being such that there will be no free play of the same.

may herebe stated that since this nut is subjected to severe strains in the opening.

and closing'of a window, it is preferable to utilize a double thread soas to provide 'a 4 Mounted upon the screw 18:is a traveling nut'23 and it screw to another upon rotation of the same. Projecting from this traveling nut is a-radial lug 24, to which are pivoted links 25 which extend to and are connected at their 5 other end s, as-at 26, to the end'of the actuating lever 14: so that when the nut travels along the screw, its motion will be'communicated to the lever'and the block 11 will ride in the slot in the member 12 to cause the window to open or close. As will be clear from Fig. 1, a squared end 27 of the traveling screw vextends through a suitable aperture in the apron or trim 2 of the window frame, so that a crank handle28 may 15 be readily applied to the same when it is desired to open or close the window, the other parts of the device, however, being located in the chamber a and thus concealed from view. Since the device described is compact in construction, it is adapted to be readily positioned under the stool even in the existing forms of window frames. Assuming that "the window is closed and that the actuating mechanism is positioned as is shown in full linesin Fig. 3, the screw is rotated in a counter-clockwise direction, whichwill cause the traveling nut 23 to appreach the other end of the screw. Since the link in its normal position is substantially parallel to the axis of the screw, the

force which is exerted on the end of the actuating lever through the link willbe substantially parallel to the-direction of line of travel ofthe nut and for this reason the window is readily opened and as the window swings out, due to the eccentric mounting of the actuating lever and-the window sash, --the block 11 willride outwardly in the slot in the member 12 increasing the leverage of. 4 the actuating lever on the window as the latter opens, from which position it may the closed by the reverse operation. It may here be remarked that whether .the window 'is closed or in any, of its open positions, the

use of atraveler and screw 01f this character 'will maintain the window'in a fixed position without the use of any latches or any other holdin devices, as the traveling nut can only be isplaced by the rotation of the screw.

Referring now to the construction shown in Figs. 4 and 5, wherein I haye'disclosed a similar actuating mechanism for'operating a transom, the'jamb of the door in-these views is designated 30, the side trims of the door casing 3l"and 32, respectiVely and the buck or. post "to'which therjamb and trims, are secured, 33, the jamb being spaced from.

this post a sufiicient distance to leave an intervening space 6, which. extends verti-- cally the entire 'fheight of, the door. casing, j

and in the form illustrated extends above the lintel bar 34 and'the transom-35, only a portion of whichfis shown, which space I 5 Sis-adapted to receive thej fictuatingni'echa 7 'pin having a centrally 43 which fit intocorrespondingly shaped ed in a similar bushing 54, the sleeve 53 nism for the transom so that itis'entirely concealed from View." Thetransom is pivoted adjacent its bottomv on one side thereof by, any usual construction (not shown) and on the other side by means of a plate 36 which is inset into the side-edge of the tranv som sashv and to which there is se'cnreda pivot 37, the same consistin of a cylindrical disposed opening there-through through which a screw 38' is adapted to pass, the plate being counter sunk at 39, for the head of this screw. The pivot pin 37 carries projecting-lugs 40 in. its end. face whichare adapted to fit into correspondingly shaped openings in they plate so as to rigidly secure these parts together. The other end of. the pin has 1 rigidly secured to it a crank arm 42,- which is positioned vin-the space I), by means of openings in the crank arm, the crank arm? being held against the pin by a nut {L4,which is threaded onto the end of the screw 38.,- The pivot pin 37 rotates in a brass bushing 45, which passes through the jamb of the door; A long-narrow substantial plate 46 ii positioned in the chamber 6 by nuts 47 t readed on the ends of screws 48 passing, through the jamb and suitable openings in the plate which nuts firmly clamp the plates against the inner face of the .jamb. The upper end of plate 46 is provided with a suitable aperture through which the, end of the bushing 45 passes, these parts being sei cured together by a screw 48 passing through the jamb. of the door. The lower end of the plate 46 is bent apgularly to form a seat and has riveted. or otherwise secured to it a U-shaped yoke 50 which in the assembly of the parts would be substantially onthe level of the door knob of the door", it being understood, that in the drawings the parts are foreshortened 'byomitting vertical sections ofkthe parts so thatthey may be clearly shownon an enlarged scale. This yoke which is; of a width, to fit between the side trims '31 and 32 on the'door casing, forms thesupporting structure for a screw 51- similar to the one heretofore described. One end of the screw zrota'tes in a suitable bushing 52; threaded into aniopening in one of the upstanding sides of the yoke, whileth th d vhassecured to it a cylindrical piece" or sleeve 53 which is suitably. supportpassingthrough a suitable recessin one of the side trims of the door casing and hav- ,inga centrally disposed squared recess in its outer end which formsi asocketfor ia crank handle.-- Mounted up on this screw, as in the first form illustrated, is a travel ing nnti5fi which has alsosecured to it be 'tweenits two spaced"lugs', -a link 56. "The ether-endof the linki is pivoted to a bell lever, ,is fpivotally, secured the bell-crank lever to which the link 56 is pivoted being preferably bent to permit the remaining portion of the lever to lie substantially flat against the plate 46. The other arm 59 of the bell-crank lever is connected by means of a rod 60 to the crank arm 42. An escutcheon plate 60 is secured to the side trim of the door-o'asing and has an opening therein through which the squared end of ahub-shaft 61 of the operating crank may be inserted into the socket the'sleeve 53. The crank arm 62 is pivoted to this hub-shaft as at 63 while secured to the inner face of the arm is a cushion 64: of rubber or other soft material. If the crank arm should be inadvertently left in a horizontal position extending into the path of swing of the door, the latter in opening will strike against the cushion 64 and swing the crank arm out of its path, thereby preventing breakage or injury of the parts. The operation of the form of the device shown in these two views is similar to that already described; by rotating the screw 51 the traveling nut 55 may be caused to travell from left to right which will, through its link connection, raise theQouter arm 59 of the bell-crank lever and hence swing the transom on its pivot outwardly as is shown in dotted lines. It will be seen, however, that in this construction, when the transom'is in its open position, the force necessary to close the same is greater than when it is in closed position a nd'this is compensated for by so proportioning the link and its position with reference to the bell-crank that as the .transom swings to its open position, the link swings farther away from the screwso thatv the travel of the nut along the screw to swing the transom through the same angular displacement is greater. This is clear from Fig. 4 wherein the dotted. line position shows th half open and fully opened posi-v tions of t e transom. To move the transom from its fully open position toward an in termediate position, the nut is therefore forced to travel a greater distance along the rotating screw and since the force applied to the crank handle may be regarded as con-' stant, the power will be increased. This 21 dditional power will also be supplied in operating the casement and would be more apparent if the window were designed to swing through an obtuse angle in which instance the link would then move farther away from the screw similar to the operation of-the link shown in the transom operating mechanism, it beingunderstood that the length of the screw would be increased the necessary amount to give the greater angular displacement. In both forms, therefore, additional power may be supplied in the initial movement of the swinging closure from its fully-open position and depend-* ing upon the angular displacement of the pivoted link from its position parallel to the threaded shaft or screw.

The transom may be pivoted adjacent its upper edge instead, of along the bottom which would only require the position of the traveling nut to be changed'so that when the transom is "closed, the nut stands at the right end of screw instead of at the left end as it is now shown.

While I have shown my invention in two of its chief embodiments, 'yet it is obvious that the structure of the easement and transom shown is by way of description only and not by limitation, as it is possible to use a device bf this character with allforms of swinglng-closures, and it is not my inten- .2.
