This invention relates to improvements in a chain type door fastener.

It is the primary object of the invention to provide a novel, simple, inexpensive and attractive appearing apparatus which will be more desirable from the standpoint of its appearance than the relatively expensive devices commonly used for this purpose. It is particularly my purpose to provide a fastener in which a shoe engages'a flanged rail on the anchorage plate connected with the door, whereby not merely to permit the chain to be fastened to and released from the door with unusual facility, but also to eliminate the unsatisfactory slot or aperture with which such anchorage plates have heretofore been provided and through which the finish of the dooris exposed and frequently subjected to scratching. In the present device the plate completely covers that portion of the door to whichit is applied and protects the finish about the rail from being marred by the shoe.

It is a further object of the invention to provide a novel, attractive, inexpensive and simplified form of jamb plate which in one simple fitting includes a mounting for the chain and a support for the shoe when the latter is not in use to fasten the door.

In the drawing:

Figure 1 is a front elevation of a device embodying the invention as it appears when applied to a door and door casing.

Figure 2 is a longitudinal section through the anchorage plate in the plane indicated at 22 in Figure 1.

Figure 3 is a view through the jamb plate taken in section in the plane indicated at 3-3 in Figure 1 and illustrating in side elevation the shoe in a position to be mounted on the jamb plate.

Figure 4 is a view taken in section through an anchorage plate in the plane indicated at 4- -4 in Figure 1.

Like parts are identified by the same reference characters throughout the several views.

Upon the jamb is mounted the jamb plate 5 which, as shown in Fig. 3, preferably has a peripheral flange 6 supporting it from the woodwork. This plate comprises a simple stamping apertured at 'l to receive the neck portion 8 of an offset fitting having its head welded at 9 to the interior of plate 5 and having a tapered terminal portion l held in spaced relation to the front of plate by means of the rivet ll. Upon the shank 8 of this fitting is mounted the last link of the usual connecting chain IS. The terminal ID of this fitting is adapted to receive and support the shoe I6 to which the free end of the chain is connected. The shoe has flanges l1 engageable' about the exposed side margins of the fitting terminal ID in the same manner in which the shoe engages the flanges of the anchorage plate now to be described. V

The anchorage plate is similar in design to the jamb plate 5, being peripherally fianged at 2| for supportfrom the woodwork. At a' plurality of spaced points the plate 29 is provided with slots at 22 having a general direction longitudinal with respect to the plate. At its end nearest the jambs of the door, the plate has a transverse slot at 23. In these severalplates a rail for the shoe I6 is mounted.

The rail preferably comprises a single piece of. sheet metal folded upon itself at laterally spaced lines to provide the two ply lateral flanges ills side marginal portions brought together by this folding operation extend in face contact as shown at 25, to the upper surface of plate 2E against which they abut. At proper intervals they are provided with registering ears ZBwhich extend through slots 22 in plate 26 and are upset to secure the rail assembly rigidly to said plate.

At the forward end of the rail, the abutting marginal portions of the sheet metal blank terminate at 21, and the portions thereof comprising flanges 24 are bent downwardly at 28,

extended through the aperture 23 and upset at 29. The portions 28 of flanges 24 are thus disposed at right angles to plate 28 and comprise a stop positively limiting the extent to which the shoe I? can slide upon the rail. The front margin 27 of the supporting portions 25 ofthe rail is concealed by the downwardly turned portions 28 of the flanges. The low rectilinear form of the rail is not only attractive in appearance and neat and simple in construction, but enables the shoe 16 to be slid on to and from the rail with great expedition.

It will be obvious that when the shoe I6 is engaged with the-anchorage plate rail as shown in Fig. 1, the chain I5 constitutes a connectionbea 1. A door fastening chain device comprising the combination with a chain and a shoe, of an apertured anchorage plate and a rail mounted on said plate to receive said shoe and comprising a piece of sheet metal folded to provide rectilinearly disposed laterally overhanging flanges, and a centrally located mounting portion beneath said flanges and connected with said plate through said apertures.

2. In a device of the character described, an anchorage device comprising an apertured plate and a rectilinear sheet metal rail mounted thereon and comprising marginal portions in face abutment having ears extended through the" apertures of said plate and upset in contact therewith, the intermediate portions of the material comprising said rail being folded to provide opposite laterally overhanging flanges extending about the end of said marginal portions and through said plate.

3. In a device of the character described, the combination with a chain, of a plate, a chain mounting fitting having a reduced portion projecting from said plate and with which a link of said chain is engaged, and a terminal above said reduced portion havinglaterally projecting margins, said chain carrying at its free end a shoe engageable over said terminal about the free margins thereof.

4. The combination with a chain having at its free end a shoe provided with spaced fingers, of a mounting for said chain comprising a plate having an aperture, a fitting having a shank portion extending through said aperture and with which a link of said chain is connected, means fingers and a chain having its free end connected with said shoe, of a mounting device for said chain comprising an apertured plate, and a fltting having a shank portion extending through the aperture of the plate and connected behind said plate to its rear face, the chain being mounted on the shank portion of said fitting in front of said plate, and said fitting having an enlarged terminal with free marginal flanges about which the fingers of said shoe are detachably engageable, a post being disposed intermediate said flanges to support said terminal in spaced relation to said plate.

6. In a device of the character described, a shoe anchorage comprising a rail having a head and a support, said head comprising a pair of laterally extending flanges of multiple ply thickness, the top of said rail comprising a single web of metal continuous across said head to comprise the top ply of both of said head flanges, each margin of said web being bent back upon itself to comprise second plies for the respective head flanges in substantial contact with'the respective top plies thereof,-and a base substantially paralleling said head flanges connected to said head by said support.

7. In a door fastener, an anchorage device comprising the combination with a mounting plate, of a support extending longitudinally thereof and comprising a sheet metal Web of substantially uniform height and'multiple ply having integral tongues interlocked with said plate, and a head mounted on said support at a spaced distance from said base determined by the height of said support, said head comprising marginal portions laterally overhanging said support and extended at one end of said support to comprise a stop for a shoe guided upon saidhead.
