eiectually retaining the same against vertical'-` movement and wear,-

and

` which vvilllat the same time `exert atighteiiing v e pull on the door in aline parallel to the plane n `10 of the door thus y1, preventing any rattle that may resultfrom movement and Wear in this direction. It is.particularlyproposed, in the exemplary Vembodiment illustrated, to provide a device in .which a'socketmember isA provided S With selfv adjustable :resiliently supported dovetail members adapted "tohave a Wedge v meinb er engaged'betvveen them, the respective dovetail members'being supported against vertical `movement, and in which there isa 21) dovetail engagementV .between the dovetailx'riembers and the wedgeimember exerting a i Vforce in a horizontal line' .transversely.or` the Flateraladjust'nfient of said members. 1 y

Inclined faces 28 extend from .the flat faces 27 tothe for- Vward ends of the blocks in diverging relation, and are diagonally chamfered or undercut, so that they diverge from their upper to their lower edges, the lower edges being set back from the flat faces 27 as clearly indicated in Fig. 9. The faces 28 are slightly arcuate longitudinally which permits firm engagement of the wedge member irrespective of slight variations in the vertical alignment of the door Pockets 29 are provided inthe rear walls of the blocks within which are engaged coil springs 30 positioned-upon the lugs 25 of the casing, and which press the blocks forwardly against the flange 13, as shown in Fig. 1, while permitting them to be forced laterally inwardly as shown in Figs. 6, 7 and 8.

The blocks are'preferably assembled within the casing through Vthe opening 15,.this being done conveniently by first inserting one ofthe blocks and its spring, and then inserting the other block and its spring, pressing the first block inwardly-while the second block is being inserted. The blocks may be of any suitable material, and because of the protection against breakage afforded by the casing, maybe of fibre, bakelite, or other suitable squeak preventing, self-lubricating material. Y Y A The wedge member comprises'an attachingl base 31 having counter-sunk screw holes 32, and a rigid wedge projection 33, having inclined undercut faces 34 substantially corresponding to the inclined chamfered faces 28 of the blocks 26. A reduced Vneck 36 portion connectsthe faces 34to the base, and

the forward triangular face 36 of the wedgeV projection is slightly projected with respect to the neck portion and the base, so that'it may bey clear of the plate 12 of the socket vmember in the engaged relation of the wedge members as indicated in Fig. 8. Y

Theoperation is asA followsz- Vhen the door is in open position the blocks 26 are Yprojected. forwardly against the flange 13 vof the casing, as indicated in Fig. 1. As the door is closed the wedge member 33 engages between the blocks, contacting therewith before the door is completely closed, the complete closure of the' door causing the blocks to be moved laterally against the pressure of the springs, while the longitudinal inclination of the engaging surfaces is such that vertical pressure will not displace the blocks and cause vibration. The transverse inclination of the contacting surfaces provides a 'dovetail engagement which through the pressure of the blocks exerts a tightening pull on the door'in a lateral .direction parallel to the plane of the door, so that it is eft'ectually held tight in this direction and at the hinges.

The door is provided with the usual latch knot shown, which engages behind a striker on thev door frame, and the present device is such that it permits the-door to close sufficiently to allow the latch to operate, and thereupon exerts an outward pressure on the door to force the latch bolt tightly against the striker. Upon release of the latch the device exerts an opening vpressure on thedoor. Should the wedge member be out of alignment with the socket, due t0 sagging of the door or inaccurate mounting of the wedge member, the independent movement of the respective blocks will permit them to adjust themselves to the wedge surfaces and perform their cooperative retaining function.

In Fig. 10,1 have shown a modified form of the invention in which the'inclined faces 34a are transversely inclined in reverse rela'- tion to the faces 34 of the first form, and in which the forward triangular face 36ais in reverse relation, the convergence of the faces 34a being .away from the attaching base, instead of toward it as in the first form. The blocks 26 are arranged rin the casing inreverse relation as shown, and in operation eX- ert a lat-eral 'pushing' force transversely 'of the direction of movement of the blocks.

While I have shown the socket member on the door frame and the vwedge member on the door, it will be'obvious that this arrangement may be reversed,`if desired. Y

A, I have illustrated and described'vpreferred and satisfactory embodiments ofthe invention, but it will be obvious thatl changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.
