The batten B is in two pieces. The top piece serves as a brace for the spring (Fig. G, [209]) and the bottom piece as a support for the bolt (Fig. H, [209] and [212]). The battens may be made of a piece of board. The bolt (Fig. H, [212]) works free upon a nail in the left-hand end and rests in the catch (Fig. K, [215]) on the door-jamb.

The guard (Fig. J, [216]) fits over the bolt and keeps it in place. The notch in the guard must be long enough to give the bolt free play up and down.

The spring (Fig. G, [209]) is fastened with a nail to the door in such a manner that its thin end rests upon the top of the bolt with sufficient force to bend the spring and hold the bolt down in the catch (Fig. K, [215]).

The thumb-latch (Fig. L, [213]) is whittled out in the form shown, and fastened in a slot cut in the door by a nail driven through the edge of the door (Fig. M, [213]) and through a hole in the thumb-latch (Fig. L, [213]). On this nail the latch works up and down.

[Fig. 217] shows the outside of the door and you can see that by pressing down the thumb-latch on the outside it will lift it up on the inside, and with it the bolt lifts up the free end of the latch and thus unfastens the door.

The handle (Figs. [217] and [214] N) is used in place of a door-knob. It is made of yellow birch bent in hot water.

The Deming Twin Lock

E. W. Deming, the painter of Indian pictures, the mighty hunter, and fellow member of the Camp-Fire Club of America, is a great woodsman. Not only is he a great woodsman but he is the father of twins, and so we have thought that he possesses all the characteristics necessary to entitle him to a place in this book, and after him and his twins we have named the twin bolts shown by [Fig. 208.]

The lower or Hall bolt is shot into a hole in the door-sill, and the upper or Billy bolt is shot into a hole in the door-jamb above the door. The holes should be protected upon the surface of the wood by pieces of tin or sheet iron with holes cut in them to admit the bolt. The tins may be tacked over the bolt-hole in the sill for the Hall bolt and on the bolt-hole overhead for the Billy bolt, and it will prevent the splitting away of the wood around the holes.
