TRANSOM CONTROLLER Refiled for abandoned application Serial No. 215,218, filed February 2, 1918. This applioation'filed May 2, 1929. Serial n 359,9?1. Y

This invention relates to new and useful improvements in transom controllers, being a refiling of application filed Feb. 2, 1918, Serial No. 215,218, abandoned March 7, 1924, 5 and theprincipal object of the invention is to provide a device adapted for opening and closing ordinary hinged transoms by the mere pulling of a chain. 7 I Another object of the invention is to pro- 10 vide. a spring for holding the transom in either open or closed position which spring holds the devicein either of its positions and also acts to move the same when the connecting links are in proper position for such 15 movement.

A still further object of the invention is to Figure 2 is a sectional view on line 22 of Figure 1 showing the same on an enlarged scale and illustrating the transom closed,

Figure 3 is a view illustrating the transom opened, and i i Figure 4 is a diagrammatic view of the device showing the method of operation.

Referring to the drawings the numeral 1 designates an ordinary door casing having hingedly connected thereto the transom 2 which'is preferably hinged at its lower edge to thelintel and is arranged to open in the ordinary way. Attached to the transom near its upper edge is the inwardly extending arm 3 provided with an angular extension at its inner end which is connected to one end of the elbow which will be more fully herein- 46 after described. The arm 3 forms the controlling arm by means of which the transom is moved.

Secured to the casing 1 is a plate 5. This plate 5 is formed with an outwardly extending ear 6 to which'a link 7 is pivoted and this link extends outwardly therefrom and is pro vided near its outer end with a stop 8 while a suitable aperture 9 is provided near the inner end of said link and is adapted to re ceive the hooked end ofa suitable connecting element for the spring wl'nch'willbe more Iully herein'aiter described. The extreme outerend of the link 7' is pivotally connected as at '10 to a link 11 the opposite end of which 1s ap'ertured to pivotallyreceive theend of the arm 3. An extension '12'isiiormed on the link 11 and projects beyond the end to which the link 7 is pivoted and this extension'12 is apertured at-13fto3 receive the uppermost d link of a suitable chain 14 or other suitable flexible member. 7 This extension 12 is adapted to engage the stop-8'when the transom is in open position and thus the links 7 and 11 are prevented from moving beyonda predetermined point. I

Extending through the opening 9 is a suitable hook 15 formed at the lower end of a connecting element 16, the upper end of which is provided with an eye 17 to which the lower end of a tractile coil spring 18 is connected. The upper end of said coil spring is connected to a screw eye 19 which is attached tothe casing 1. g

It will be apparent from the ir'oregoing that in useassuming that the transom is closed, pull is exerted on the chain 14 thus causing the link ll to. swing on the pivot 10 and tend topullthe upper end of said link outwardly thus moving the" transom on its hinge. The swinging movement of the} transom willswing the link 11 beyond the perpendicular and simultaneously swing the link 7 downwardly until the links assume the positions shown in Fig. '3 at which time the transom is fully open, When it is desired to close the transom, pull is again exerted on the chain 14 thus breaking the elbow-joint formed by the links 7 and '11 and due toy the pull of the spring 18 the transom will be moved to closed position.

While in the foregoing there" has been shown and described the preferred embodiment of this invention, it is tobe understood that such changes may be made in the combination and arrangement of-part-s as will fall within the spirit and scope of the invention as claimed.

What-is claimed is p In a closure operator, the combinationwith a hinged closure and'a fixed support, a link pivoted to said closure, a second link, said second link being pivoted to said fixed support and at'a point intermediate its ends to the first link to provide a free end extension on the first link beyond the last mentioned" pivot, a spring connected to the second link adjacent its pivotal connection with the fixed support and connected to the fixed support substantially abo vethe last mentioned pivotal connection, a flexible operating member connected to the extension, and a stop on said second link to cooperate with said extension when the closure is in fully openedposition said spring operating to hold the hinged closure in closed position, in one adjustment of saidlinks and in another adjustment with t the extension engaging the stop holding the links in extended relation with the closure in openposition, pull on saidfiexible member in the same direction and against the tension of said spring operating to release the closure from its position either when open or closed, the tension of the spring completing the movement whenpull on the flexible member is relieved. I

In testimony whereof I aflix my signature.

CHRIST S. MINNEOI.
