`DOOR-JAMB.

SPECIFICATION forming part of Letters Patent No. 367,626, dated August, 2, 1887.t

Application filed November 5), IBPG, Serial No, 218,414. (No model.)

lo @ZZ whom it may concern,.-

Be it known that I, GHRIs'rIAN HENRIcsoN, `of Ashland, in the county of Ashland and State of Visconsin, have invented new and useful Improvements in Door-Jambs, of which `the following is a specification, reference behorizontal section taken on line :v x in Fig. l;

and Fig. 3 is a longitudinal section of one of the jamb-holders, taken on line g/ y in Fig. 2.

Similar letters of reference indicate corresponding parts in all the views. A

The object of my invention is to provide a yielding door-janlb, which will compensate for the swelling or shrinking` of the door, and which will always rest in contact with the edge of the door when the door is closed.

My invention consists in a door-jamb facing supported and guided by horizontal rods and pressed forward into contact with the edge of the door by springs.

The door A, which is ofthe usual form and construction, is hung in the door-casing B, upon hinges a. In the upright C, on thelatch side of the door, are inserted the sockets Z) b b, having cavities c, in which are placed spiral springs d. Rods c extend longitudinally through each socket, each rod passing through one ot' thc spiral springs. Upon the rods e c, in the cavities c c, are placed the sliding blocks f f, which are pressed forward toward the door by the spiral springs d. It will thus be seen that the rods e form guides for both the springs and the sliding blocks.

In each block f is formed a screwtlireaded hole, g, and to the front of the upright C is titted a facing-strip, D, which is held in place by screws h, entering the screw-threaded holes g in the sliding blocks j. The facing-strip D carries the keeper fi, which is engaged by the beveled bolt of the door-latch j.

Vhen the door is opened, the facing-strip D is pushed forward by the springs d toward the door-opening and into the path of the free edge of the door, its motion in that direction being limited by the striking of the sliding blocksf against the ends of the cavities in the sockets b b. \Vhi1e the door is being closed the engagement of the beveled end of the doorlatch with the keeper t' pushes back the facing D of the door-casing, so that the door can close. \Vhen the latch slips into the keeper i, the springs d force the facing D against the edge of the door, thus making a tight joint.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patei1tl. The combination, with the sliding doorfacing strip D, of the sliding rods e, the blocks f, secured thereon and to said strip, the springs d, encircling said rods` and the sockets b b', which are fixed in position and serve as supports and guides for the rods, as shown and described. y

2. As an improved article of manufacture, a yielding support for the facing of a doorcasing, formed ofthe socket I), having cavities c, the rods e, springs d, surrounding the rods, the sliding blocks f, placed on the rods and pressed by the springs d, and the screws l1., fitted to threaded holes in the sliding blocks, substanlially'as described.
