TRANSOM.
To all whom it may concern Be it known that I, ALEXANDER KNox, a subject of the King of Great Britain, residing at Brisbane, Queensland, Commonwealth of Australia, have invented certain new and useful Improvements in Transoms, of which the following is a full, clear, and exact description.
This invention relates totransoms, and its chief object is to provide an improved transom and opening and closing mechanism therefor which shall be moved more conveniently in useand more easily operated than the devices heretofore employed.
To this and other ends the invention consists in the novel features of construction and combinations of elements hereinafter described, and more particularly set forth in the appended claims.
A convenient and effective embodimentis illustrated in the accompanying drawings, in which V Figure 1 is a front view of a door with my improved transom. Fig. 2 is a detail view of the transom-operating mechanism, a portion of the door frame being bro-ken away. Fig. 3 is a vertical sectional view showing the transom closed. Fig. 4 is a vertical sectional view showing the transom open. Fig. 5 is a? detail sectional view on line 5-5 of Fig. 2, looking in the direction of the arrows. Fig. 6 is a vertical sectional view of a modification, with the transom in open position. I
In the preferred form of my transom there are two sashes, an upper and a lower,
of equal size, as shown at 10, 11. The inner faces of the meeting rails 12, 13 are provided with grooves 14, 15 registering with each other when the sashes are closed, to accommodate a transverse shaft 16 journaled in the parting strips 17 which separate the two sashes. At its ends this shaft is provided with balance levers 18, 19, the upper ends of which are pivotally attached to the styles 20, 21 of the upper sash 10 and the lower ends of the styles 22, 23 of the lower sash 11. The top rail 24 of the upper sash and the bottom rail 25 of the lower sash are equipped at each end with laterally extending pins 26, 27, extending into upright grooves 28, 29, in the sides 30, 31 of the transom frame and capable of sliding vertically therein. It will now be seen that if the shaft 17 be rocked, counter-clockwise as viewed in Fig. 3, the balance levers will Specification of Letters Patent.

be swung to the position indicated in Fig. 4, thereby swinging the bottom of the upper sash and the top of the lowersash outwardly on the pins 26 and 27 as pivots while the pins themselves move respectively down and up 111 the grooves 28, 29. This leaves three openings through the transom: between the two sashes at the center, above the upper sash, and below the lower sash. To close the transom it is only necessary to rock the shaft 17 in the opposite direction, clockwise ,as viewed in Fig. 4, thereby restoring the two sashes to the position shown in Fig. 3 For the purpose of thus rocking the shaft 17 1t 1s provided at one end with an arm 30, pivotally connected to the upper end of a vertically movable rod 31 provided at its lower end with a toothed rack 32 meshing with a gear segment 33; the arm, rod, and gear ar anged in suitable recesses 34, 35, 36 111 the side of the door frame, which recesses are covered by the door frame casing 37, completely concealing the operating parts named. The shaft 38 on which the gear segment is fixed extends outwardly through the casing handle 39, so that by turning the handle the actuating rod 31 will be reciprocated to rock the shaft 17 and operate the transom sashes as explained above.
In the form shown in Fig. 6 a single sash, 40, is used, and the balance levers, one of which is shown at 41, are consequently only half as long. In this case reciprocation of the actuating rod 42 to open the transom causes the sash to move upwardly and to swing outwardly as indicated in the figure.
From the foregoing it will be seen that theunsightly operating mechanism heretofore commonly used for transoms is in my invention replaced by devices which are concealed except the actuating handle, which is no more unsightly or obtrusive in appearance than a doorknob. Moreover, the force used in operating the transom sash or sashes is applied equally at both sides, thereby eliminating the tendency to bind, with severe strain. on the parts, so often met with in transom-actuating devices hitherto employed. My improved transom is also more effective for ventilation, as the combined area of the several openings is, in general, greater than the capacity of the single opening afforded by the ordinary transom. At the same time dividing up the ventilating space into several openings is also advantageous in that none of the several openings is large enough to permit a person to crawl through, so that my transom is far safer from the standpoint of preventing unauthorized entry into the room and for this reason is particularly valuable for use in hotels and other buildings open to the public.
While I prefer the forms herein specifically illustrated. and described it is to be understood that the invention is capable of other embodiments without departing from its proper spirit and scope as defined by the following claims.
I claim:
1. In a transom, the combination of a pivotally and vertically movable sash, actuating levers at the sides of the sash to move the same, and means for actuating the levers in unison.
2. In a transom, the combination of a pivotally and vertically movable sash, actuating levers at the sides of the sash to move the same, a rock shaft on which the levers are mounted, and manual means for rocking the shaft.
' 3. In a transom, the combination of a pivotally and vertically movable sash, a shaft extending across the sash, levers mounted on the shaft and pivotally connected to the sash at the sides thereof, and manual means for rocking the shaft.
4. In a transom, the combination of a frame, a pivotally and vertically movable sash therein, a shaft journaled in the sides of the frame and extending across the sash, levers mounted on the shaft and pivotally connected to the sash at the sides of the same, an actuating arm on the end of the shaft, a reciprocatory rod connected to the arm to actuate the same, said arm and rod being concealed in the side of the frame, and manual means associated with the rod to reciprocate the same.
5. In a transom, the combination with upper and lower sashes movable pivotally and vertically, levers at the sides of the sashes, each lever fulcrumed between its ends and connected at its ends to the sashes, means connecting the levers to actuate the same in unison, and manual means to operate said means.
6. In a transom, the combination of upper and lower sashes movable pivotally and vertically, a shaft extending across the sashes between the meeting rails thereof, said rails being grooved to accommodate the shaft, levers mounted on the shaft and pivotally connected at their ends to the sides of the sashes, and manual means to rock the shaft.
7. In a transom, the combination of upper and lower sashes movable pivotally and vertically, a shaft extending across the sashes between the meeting rails thereof, said rails being grooved to accommodate the shaft, levers mounted on the shaft and pivotally connected at their ends to the sashes, an arm 011 the shaft to rock the same, and a reciprocatory member connected with the arm to actuate the same.
8. In a transom, the combination of a frame, .upper and lower sashes vertically and pivotally movable in the frame, a shaft journaled at the sides of the frame and extending across the sashes between the meetmg ralls thereof, the said rails being grooved to accommodate the shaft, levers mounted on the shaft and pivotally connected at their ends to the sides of the sashes, and manually actuated means c0ncealed in the side of the frame to rock the shaft.
In testimony whereof I affix my signature in the presence of two subscribing witnesses.
