.To all whom t may concern.'

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in T ransom- Operators, of which the following is a full, clear, and eXact description. I

This invention relates .to transom operators, and more particularly to devices of the type in which the main operating parts are concealed from view within the casing of the door frame.

One of the primary objects of the invention is to provide a transom operator in which the transom when in closed position is locked in place by means other than the transom swinging means, which locking means, however, is automatically released by the transom swinging or opening means in the operation ofV moving the transom to open position. By this arrangement or construction, the transom may be securely locked and firmly held in the closed position, and yet the opening and closing operations are not complicated in any way, owing to the fact that the manipulation of the transom can be controlled entirely by a single hand crank, or the like.

Another object-of the invention is to provide a simple, inexpensive, compact transom operator, which is very efficient in use, and which can be very readily applied.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed. v

In the accompanying drawings, Figure 1 is a front elevation of a portion of a door frame'and transom, to which my improvements are applied; Fig. 2 is a fragmentary front elevation on a larger scale, with certain parts broken away; Fig. 3 is a side elevation of the parts shown in Fig. 2, with the transom in a closed position, partly in section on line 3*3 of-Fg. 2; Fig. 3A is an enlarged detail of a portion of Fig. 3; Fig. a is a view similar to Fig. 3, `but showing the transom in the open position; Fig. 5 is a detail vertical section, through the transom lock and its releasing means, with the bolt in locking position; Fig. 6 is a view similar to Fig. 5, showing the bolt in the released position preparatory to opening the transom; Fig. 7 is a section on line 7-7 of Fig. 6; Fig. 8 is a detail of the mechanism for lifting and lowering the operating rod; and Fig. 9 is a detail perspective view of the releasing cam for the transom locking bolt.

Referringto the drawings, the transom 10 of usual form is hinged to its frame in the customary manner by hinges 11 (of which only one is shown), and the transom operating means is housed'for the most part in the door casing 12. This operating means includes a vertically movable rod 13 adapted to be raised and lowered by means projecting out of the door casing, such, for example, as the hand crank ll. On the rear surface of the plate or member 12, which carries the door jamb or stop bead, is applied a carrier for the main parts of the transom operator, which carrier is preferably in the form of a metallic strip or bar 15, which may be conveniently attached to its support by means of screws or the like. At its upper end, the strip or bar 15 carries a bracket 16, which may be formed separately from the bar 15 and attached thereto by means'of screws 17, as shown in Figs. 5 and 6. The bracket 16 forms a bearing for the upper end portion of the upright rod 13. At its lower end portion, the supporting bar carries a U-shaped bracket 18, which may be conveniently secured thereto. The lower end portion of the rod is offset and threaded, as indicated at 13a, and this offset threaded portion passes through registering perforations in the upper and lower portions of the bracket, as shown in Figs. 3 and 4. YIn the upper perforation, a small bevel gear 19 is rotatably mounted and held against vertical displacement by a Vplate 20 on the bracket, as shown in Fig. 8. The gear 19 is provided with interior screw threads engaging Vthe threads on the rod suoli that, as the gear is turned on its axis, the rod is raised or lowered, depending upon the direction of rotation. lThe gear 19 is given this rotary movement by means of a larger bevel gear 21, having a stem or arbor 22, journaled in a hub portion 23 on the intermediate portion of the bracket 18. The hand crank 1l previously mentioned is mounted on the stem 22 so that by rotating the gear 21, in one or the other direction, the rod 18 may be raised or lowered through the described connections.

rlfhe rod 13 is operatively connected with the transom, so as to swing the latter to open and closed positions, by means of the following mechanism: The door frame member 122L is provided with an upright slot adjacent the lower portion of the transom 10, as indicated at 2li. ln this slot, `a sliding member 25 is guided. The member 25 includes a sleeve portion embracing the rod 13, as best shown in Fig. 3, and is held in a predetermined position relative to said rod by means of a transverse pin 26 extending thii'ough the rod and located in a notch 27 inthe sleeve portion. From thissleeve portion of the slide member extends a shank portion 2S which is guided in a slot 15a of plate or Abar 15, and in the previously mentioned slot 2st in the door frame. The inner end of the shank portion 28 is pivoted to one end of a link :29, and the other end of the link is pivoted in a mortise 30 on the side edge ofthe transom by means of a pivot 31 of suitable form. The mortise in the transome stile is lined by a suitable metal plate, asbest shown at 32, in Figs. 5 and 6, and this mortise accommodates the link 29, so that the outer face of said link will be iiush with the edge of the transom stile. Vhen the transom is in the closed position, the slide 25 is'adjacent the lower hinged edge of thev transom, as shown in Figs. 2 and 3. As .the rod 13 is raised by means of the crank 14, Athe slide is carried up with it by virtue of the engagement of the pin 26 with the upper edge of the notch 27, and as the slide is raised, carrying vwith it the lower end of the link, the transom is forced outward into the open position, and held in that position by means of the link, as shown in Fig. el.

-Referring now to the means for locking the transom inthe closed position, I prefer Yto use a construction substantially like the embracing the shank of the bolt 33 normally holds the latter in an outwardly .projected position. rlhe face plate 35 is substantially flush with the edge of the transom stile above the mortise 30. The bolt is adapted vto engage an elongated opening 37 of a strike member 38 applied tothe supporting member 12a, as shown in Figs. 5 and 6,

adjacent the upper bearing l'for the operating rod. The strike 3S is formed with a hollowV portion or recess 39, within which is movable a latch actuating member 40.

ln the form shown, this member 40 is pivoted between lugs 41' on the bracket 16 by means of a pin 42, in such a manner as to swing in a vertical plane. It is provided at its forward end with a curved surface lf3 in the nature of a cam, to act upon the latch i" bolt in the manner hereinafter described.

it itsV rear end, the pivoted member f-lO isV provided with a shoulder est, whereby it is actuated by the operating rod 13. In the locked position of the transonnthe unlocking member l0 has aninclined position, as shown in Fig. 5, with its shouldered overhanging the upper end of the operating rod; but as the rod is moved upwardly, it swings down the unlocking member, as shown in shown in Fig. 6 the upper end ofthe rod 13 Y may be moved upward beyond the member l0, while said member by engaging the side surface of the rod is held in the unlocked position. Y.

The operation of the `device 'is substantially as follows: Assuming the parts to be in the position shown in Figs. l, 2 and 3, the transom can be opened by turning the crank lll in a direction to raise the operating rod 13. During the preliminary part of the upward movement of the rod, the slide is inactive, it being held in the lowermost portion of the guide slot 2l by means of a spring l5, embracing the rod 13 betr-kfw said slide and the upper bearing 16, while the pin 26 moves from the lower edge of the notch 27 to the upper edge thereof. During this time, the upper end ofthe rod engages the releasing member "I0, andreleases the latch 36 in the manner previously described. Thus, the transom is released for o )ening` movement by the time the )in 26V reaches the upper edge of the notch 2 and begins to carry alongthe slide 25 to operate the actuating link .29, as will be understood. The transom may then be opened to the desired angle, and it will be held in the adjusted position in an obvious manner. 1When it is desired to close the transom, the crank 1l is rot-ated in thev opposite direction so as to pull down the operating rod, and thus return the transom tothe initial position by virtue of its connection with the downwardly moving slide 25, which begins to descend as soon as the pin 26 reaches the lower edge of the notch in the slide. As the transom nears the closed position, the projecting latch bolt 33 comes into contact with a lip 38a on the strike 3S by which it is pressed back into its case. As the bolt comes opposite the opening in the strike, it shoots out into the latter, and locks the parts again, and tilts the releasing member 40 into the position shown in Fig. 5, such tilting movement being permitted by the passage of the upper end of the operating rod downwardly beneath the shoulder 44, as will be obvious.

It will be understood that the connection of the operating rod to the slide by means of the pin 26 provides a certain amount oli lost motion between the operating member and the transom swinging mechanism, so that said member may unlock the transom preparatory to etfecting the swinging movement thereof. At the same time, the pin 26 prevents the rod from rotating, and thereby insures the proper raising and lowering of said rod by means of the threaded connection with the gear 19, which acts in the nature of a fixed nut. The spring 45 cushions the lost motion connection between the rod and the transom swinging mechanism, and makes the operation of the device steady and noiseless.

rlhe foregoing description is necessarily a detailed one, in so far as it concerns the particular embodiment selected for illustration and description, and it will be understood that various changes in the details of the construction may be adopted within the scope of the claims.
