FASTENER FOR TRANSOM-RODS.

SPECIFICATION formingpart of Letters Patent No. 556,586, dated March 17, 1896. Application filed January 16, 1896; Serial No. 575,739. (No model.)

T0 all w7wm' iz may concern:

Be it known that I, CARL OTTO NOACK, a citizen of the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Fasteners for Transom-Rods, of which the following is a specification.

This invention relates to an improved fastener for transom-rods by which the use of a clamping-screw is dispensed with and the rod either released by the simple forward motion in the guide-casing, so as to be quickly moved up or down, or rigidly locked in position by the inward motion of the rod, so as to prevent the shifting of the transom-rod and of the transom connected therewith and the invention consists of a fastener for transomrods which comprises a guide-casing that is screwed to the door-frame, said guide-casing being provided with slots in its top and bottom and a helical spring or springs that are placed around the transom-rod and the ends of which are extended so as to press against the casing and permit the release of the transom-rod when the same is moved forward in the guide-slots of the casing, or clamp the same in position when the same is moved inwardly in the guide-slots, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of a transom and transom-rod, showing my improved fastener in position on the rod. Figs. 2 and 3 are vertical central sections of the fastener on line 2 2, Fig. 4, said figures being drawn on a larger scale and showing the transom-rod respectively in locked and unlocked position, and Figs. 4 and 5 are respectively detail horizontal sections on line 4 4, Fig. 2, and line 5 5, Fig. 3.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the cast-metal casing of my improved fastener for transom-rods, which casing is made wider at its base and narrower toward its rounded-off front part, as shown in Figs. 4 and 5. The casing A is closed at the upper and lower ends, the top and bottom plates being made integral with the body of the casing and provided with slots a a, as shown in Figs. 2 and 3, the casing A being provided at an intermediate point with a web b, which is likewise provided with a slot a which is arranged in line with the slots a a, so that the transomrod B can be readily guided in forward and backward direction in said slots and moved either away from or toward the jamb of the door-frame, as shown in Figs. 2 and 3. The casing A is attached to the doorjamb by means of screws, of which two are preferably arranged on each side of the casing, as shown in Fig. l.

The transom-rod B is guided in a suitable keeper and connected by an intermediate con nectingrod with a fixed arm on the transom in the usual well-known manner. Around the transom-rod B are arranged at the inside of the casing A one or more helical steel springs C, which are made of round or square cross-section and the ends of which are extended in opposite directions, so as to press against the wider rear part of the casing A when the transom-rod B is moved toward the inner ends of the slots a, a a as shown in Figs. 2 and 4:, in which case the helical portions of the springs are drawn by the tension to which they are subjected by the ends tightly around the transom-rod B, so as to firmly clamp it in position and prevent it from being shifted in the guide-casing A. In the inner position of the transom-rod B the convolutions of the springs bite the rod, so to say, in the nature of a wedge, as they are crowded up closely to the rod, and lock thereby the transom-rod firmly in position without requiring any screw or other clamping device for this purpose.

When it is desired to release the transomrod so as to permit the shifting of the same in upward or downward direction for setting the transom into closed or open position, the rod B is moved toward the outer ends of the slots a aa as shown in Figs. 3 and 5, so that the tension on the ends of the looking-springs is released and the coiled portions of the springs by the contact of the ends with the narrower portion of the casing A enlarged and moved away from the rod, so that the same can be freely shifted in the coiled portions and set to any desired position.

When good and properly-tempered steel springs are placed inposition on the transomrod in the casing A, a very efl:ective looking device for transon1 and otherrods is obtained, which can be quickly and easily set into locked or unlocked position by simply moving the transom-rod in the casing inwardly in the slots of its guidecasing or outwardly toward the outer ends of the slots, in which latter position the transom-rod can be readily set into any desired position without extraneous clamping devices-such as screws, wedges, &c.which were heretofore employed.

For looking the transom-rod one or more Springs maybe used, according to the size and weight of the transon1 and transom-rod, larger transoms requiring two or more lookingsprin gs, while sm aller transoms can be locked by one spring only.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A fastener for transom-rods, consisting of a casing, having top and bottom slots ar ranged vertieally in line with each other, a transom-rod, passing through said slots, and

a spring, the helical or coiled portion of which is placed on the transomrod inside of the casing, and the upper and lower ends of which are extended in opposite directions, so as to produce on moving the transom-rod in outward or inward direction the releasing or looking of said rod by the helical or coiled portion of the spring, substantially as set forth.

2. A fastener for transom-rods, consisting of a casing having a Wider rear part for attachment to the door-casing and slots in its upper and lower ends, a transom-rod passing through said slots, and a spring, having a coiled portion placed around the rod and provided with ends extending inopposite directions into the wider rear part of the casing, substantially as set forth.

In testimony that I claim the foregoing as my invention1 have signed my name in presence of two subscribing witnesses.

CARL OTTO NOACK.
