6 Claims.

This invention relates to transom operators, and more specifically to transom operators for use with steel easement windows.

As is well known, the frames of such windows are relatively narrow, affording little space for the mounting of operators of the general class above noted and the available space is further reduced through the necessity in many locations of applying screens to the sash and transom openings. Accordingly, important objects of this invention are the provision of an operator which will require a very small space for its application, which may be readily installed upon the frame, and in which the more unsightly portions of the o operating mechanism are effectually concealed from view and protected from the weather when the transom is closed. g

A further object of the invention is the provision of an operator of this character which will permit the transom to be opened with the application of a relatively small force and will, at the same time, hold the transom securely in any adjusted position thereof.

These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein:

Fig. l is a front elevation of a transomed sash frame including a transom operator constructed in accordance with my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a section on line 3--3 of Fig. l;

Fig. 4 is a fragmentary perspective view, parts being broken away to show the construction and mounting of the mechanism; and

Fig. 5 is an enlarged section on line 5--5 of Fig. l.

Referring now more particularly to the draw- 4() ings, the numeral I0 generally designates a sash frame comprising-aperimetric frame member II which is substantially L-shaped in cross section, and horizontal and vertical dividing rails I2 and I3 which are substantially T-shaped in cross section, these dividing rails subdividing theframe into openings for the reception of a transom T and the usual sash. The transom T comprises a frame member I4 which is likewise substantially L-shaped in cross section, this frame member combining with rail I2 and the sash frame in the closed position of the transom to form a substantially rectangular closed channel I5. The transom is hinged .at its upper end as indicated at I6 to swing to open and closed positions and is so proportioned that proper clearances are provided between the flanges of its frame and the flanges of the sash frame until the transom arrives at its closed position, these clearances, however, being relatively slight as in the usual swinging sash construction.

-In .accordance with my invention. I arrange wlthn the lower run of the channel I5, that is to say, that run formed by the rail I2 and the lower edge of the transom. a pair of shafts I1, these shafts being arranged in bearings I8 secured to the stem portion I9 of the T member forming the rail I2.

Secured to the outer ends of the shafts I1 are thin flat arms 20, the width of these arms being such that they may readily pass through the clearance space provided between the flanges of tle sash frame and transom as the transom is opened or closed. To the sides of the transom frame and against the riser I of the L-shapecl member forming this frame, I secure an elon- L gated slide guide 22 within which a slide 23 is mounted, this slide being pivotally connected to the frame end of the associated arm at 26.

To the adjacent ends of shafts I1 I secure relatively short arms 25, these arms projecting through slots 26 formed'in the head of the T member forming the rail I2. Upon the rail I3 at a convenient level, I mount a casing 21 within which a gear nut 28 is disposed, this nut coacting with a worm 29 formed upon the lower end of a shaft 30. This nut may be rotated I through a crank-operated pinion 3|, thus causing shaft 30 to rise or fall as desired. The upper end of this shaft has a furcate head 32 provided with an abutment 33 to slide against the face of the rail I3 and in the furcation of this head a link 34 is pivotally mounted. Link 3l is, in turn, pivotally connected to the adjacent ends of arms at 35 and it will, accordingly, be obvious that as shaft rises and falls the shafts I1 will be rotated and by their rotation will cause the transom T to move about its hinges.

Shaft 30 is necessarily relatively long and, accordingly flexible, and to rmly hold the upper end thereof in properly guided relation and, at the same time, to conceal the connections which are made between the shaft and arms 25, a casing 3B is provided. This casing has a notch 31 for passage of shaft 30 which is of such depth that when the casing is in applied position it holds the shaft with the abutment 33 in proper engagement with the wall of the rail I3. While a single shaft might be employed in lieu of the shafts I 1, the construction illustrated is preferred for the reason that steel easement sash often becomes sprung and will not fit tightly at opposite sides thereof except by independent adjustment which is, of course, afforded by the double shaft arrangement.

It will be noted that the operator parts which are disposed at the face of the window are of relatively restricted size and may be readily so disposed that they vdo not interfere at all with the application of screens to the window. Shafts l1 and the arms 20 are fully protected from the weather wherf the transom is in a closed position.

While I have described the invention in conjunction with a hinged structure, `it will, of course, be obvious that the` same construction may be readily employed with the projectedvtype of sash mounting.

Since the construction is obviously capable of considerable modification without departing from the spirit of the invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1. A frame including a horizontal cross member defining a transom opening, a transom hinged to the frame at the upper edge of the opening, said transom and frame combining in the closed position of the transom to define a closed channel extending about the free edges of the transom, a shaft in the lower run of the channel, means to rotate the shaft from the exterior of the channel and` operative connections between the shaft and transom constructed and arranged to move the transom about its hinges as the shaft is rotated. y

'2. A frame including a horizontal cross member dening a transom opening, a transom hinged to the frame at the upper edge of the opening, said transom and frame combining in the closed position of the transom to define a closed chan# nel extending about the free edges of the transom, a pair of shafts in the lower run of the channel, means to simultaneously rotate the shafts from the exterior of the channel and operative connections between the outer ends of .the shafts and sides of the transom constructed and arranged to move the transom about its hinges as the shaft is rotated.

3. A frame yincluding a transom opening, a transomhinged to the frame at'one edge of the opening, said transom and frame each' comprising rectangular frame elements L-shaped in cross section, said frame elements combining in the closed position of the transom to produce a hollow channel, the flanges oi' said L-shaped members passing one another in slightly spaced relation as the transom moves from open to closed positions, a shaft secured to the frame within the channel thereof at the side of the frame opposite that to which the transom is hinged, an arm secured to the shaft and movable through the space between the flanges of the frame and transom as the transom is moved from open to closed positions and disposed within a channel at the side of the transom and frame' when the transom is in closed position, means to rotate said shaft and a slide carried by the transom within the channel of a side member thereof and pivotally connected to the free end of Asaid arm.

4. A device as claimed in claim 1 wherein the shaft has an arm projecting through a slot formed in the wall of the channel and a longitudinally movable shaft has linked connection with the free end of said arm.

5. A device as claimed in claim 1 including a longitudinally movable shaft having a screw thread at one end, a nut engaging said thread and guiding said end of the shaft, means to rotatetsaid nut and a link and arm connection between the opposite end of the longitudinallyk movable shaft and the first-named shaft.

6. A device as claimed in claim 1 including a longitudinally movable shaft having a screw thread at one end, a nut engaging said thread v and guiding said end of the shaft, means to rotate said nut, a link and arm connection between the opposite end oi.' the longitudinally movable shaft and the first-named shaft, the arm being attached to the shaft and projecting -through a slot in the channel wall, and a housing cover for said link and arm connection concealing the same from view and guiding the adjacent end of the longitudinally movable shaft.
