SECRET LOCKS

SECRET locks are more useful than strong ones for a country house which is left alone during the winter months, for it is not so much cupidity which causes such houses to be broken into as it is the curiosity of the native boys. But while these lads often do not hesitate to force or pick a lock they will seldom go as far as to smash a door to effect an entrance; hence, if your lock is concealed your house is safe from all but professional thieves, and such gentry seldom waste their time to break open a shack which contains nothing of value to them. The latches shown by Figs. 193, 200, and 201 may be made very heavy and strong, and if the trigger in Fig. 200, the latch-string hole in Fig. 193, and the peg hole in Fig. 201 are adroitly concealed they make the safest and most secure locks for summer camps, shacks, and houses.

If a large bar (Fig. 201 _B_) be made of one-by-four-inch plank, bolted in the middle of the plank with an iron bolt through the centre of the door and fastened on the inside by a nut screwed on to the bolt it will allow the bar to revolve freely on the inside of the door and bar the door when resting in the _A_ and _C_ catches. But if a string is attached to one end it may be unfastened by pulling the string up through the gimlet hole in the door.

To conceal this lock, draw the string through the gimlet hole and fasten a nail on the string. When it is undrawn the door bar is horizontal and the door consequently barred. Then push the nail in the gimlet hole so that only the head appears on the outside and no one not in the secret will ever suppose that the innocent-appearing nail is the key to unfasten the door. When you wish to open the door from the outside, pluck out the nail, pull the string, and walk in.

There are a thousand other simple contrivances which will suggest themselves to the camper, and he can find entertainment for rainy days in planning and enlarging on the ideas here given. In the real wilderness, however, every camp is open to all comers--that is, the latch-string hangs outside the door, but the real woodsmen respect the hospitality of the absent owner and replace whatever food they may use with fresh material from their own packs, wash all dishes they may use, and sweep up and leave the shack in "apple-pie" order after their uninvited visit, for this is the law of the wilderness which even horse thieves and bandits respect.

The Tippecanoe

The Tippecanoe latch is worked with a wooden spring and when properly made, of well-seasoned wood, will probably outlast a metal one, for wood will not rust and cannot rot unless subjected to moisture.

The position of the spring in Fig. 201 shows the latch with the bolt sprung back. The fact that the bolt-hole in the catch is empty also tells the same story. The drawing of the outside of the door (Fig. 203) shows by the position of the peg that the door is fastened. To open the door, push back the bolt by sliding the peg to the opposite end of the slot. From a view of the edge of the door (Fig. 202) one may see how the peg protrudes on the outside of the door.

Although the Tippecanoe latch is made of quite a number of parts, it is really a very simple device, but in order to display the simplicity of its construction to the ambitious jack-knife latch maker I have drawn all the parts but the spring stick natural size (Figs. 204 to 207), but since the original diagram is drawn too large for this page and was reduced by the engraver there is a scale of inches at the bottom to give the reader the proportions.

There are no fixed dimensions for this or any other lock, latch, or catch, but the proportions here given are probably the ones that will fit your door. The foundation block is shown by Fig. 204. Upon this the latch rests and is securely nailed or screwed to the door. Figs. 205 and 206 are two wooden clamps which are fastened to the door and also to the foundation block (Fig. 204). These clamps must be notched as in the diagrams to allow for the movement of the bolt, but since the bolt (Fig. 207) is larger and thicker at the b.u.t.t the notch in Fig. 205 is made just a trifle larger than the b.u.t.t end of the bolt and in Fig. 206 the notch is made a trifle smaller than the opposite end of the bolt. The object of the offset on the bolt (Fig. 207) forward of the peg is to make a shoulder to stop it from shooting too far when the spring is loosened.

The Catch

Figs. 201 and 204 show the catch which is to be securely fastened to the door-jamb. The spring, of course, must be made of well-seasoned, elastic wood. Hickory is the best. This stick may be quite long, say half again as long in proportion as the one shown in Fig. 201. It must be flattened at the upper end and secured by two nails and it must be flattened at right angles to the upper part and somewhat pointed at the lower end so as to fit in a notch in the bolt (Fig. 201). A well-made lock of this sort is a source of constant joy and pride to the maker and he will never tire of springing it back and forth and extolling its virtues to his guests.

HOW TO MAKE THE BOW-ARROW CABIN DOOR AND LATCH AND THE DEMING TWIN BOLTS, HALL, AND BILLY

FIG. 209 shows the inside of the door with the wooden latch in place. You may use planks from the sawmill for the door in place of splitting them from spruce logs, as the ones here are supposed to be.

The battens (_A_, _B_, _C_) are made of birch, but you may use any material at hand for them. The hinges (Figs. _E_, 211 _D_, 210) are made of birch sticks whittled off at the top so as to leave a peg (Fig. _E_, 211) to work in a hole in the flattened end of the horizontal battens (_A_ and _C_, Fig. 209).

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-k.n.o.b. 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 ent.i.tle 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.

Guards

Two guards, _A_ and _B_ (Fig. 208), made as in Fig. 216, protect the bolts and act as guides to keep them from swinging out of position; two springs _C_ and _D_ (Fig. 208), made of well-seasoned hickory and attached to the battens on the door by nails or screws, force the bolts down and up into the bolt-holes (Fig. 208). To release the bolts, the spring must be drawn back as shown by the dotted lines in Fig. 208. This may be done by means of a string or picture wire, which is fastened in the ends of the bolts and runs through a hole in the ends of the spring and is attached to the lever _E_ (Fig. 208). When the end of this lever is pushed down into the position shown by the dotted line and arrow-point, it lifts up the Hall bolt at the bottom of the door and pulls down the Billy bolt overhead, thus unfastening the door.

[Ill.u.s.tration: Jack-knife latches suitable for Canada and America.]

But, of course, if one is outside the door one cannot reach the lever _E_; so, to overcome this difficulty, a hole is bored through the central batten of the door and the latch-string is tied to the top end of the lever and the other end is run through the hole bored in the door (Fig.

208).

The end outside of the door is then tied to a nail; by pulling the nail you pull down the lever _E_, which undoes the bolts and opens the door.

When it is desired to leave the door locked, after it is closed, push the nail into the latch-string hole so that only the head will be visible from the outside. When the nail and string are arranged in this manner, a stranger will see no means of opening the door, and, as there are many nail-heads in all rough doors, the one to which the latch-string is attached will not attract the attention of any one who is unacquainted with the Deming twin bolt.

THE AURES LOCK LATCH

THE Aures lock differs from the preceding ones in the use of metal springs, but wooden ones may be subst.i.tuted; for instance, a wooden spring like the one in Fig. 209 may be put under the bolt or latch shown in Fig.

219, which is practically the same latch; that is, if you turn the latch in Fig. 209 upside down it will make the latch shown in Fig. 219; also, if you take the bolt or lock _B_ in Fig. 219 and make it of one piece of wood with a spring to it, like the one shown in Fig. 208 or Fig. 209, or make it exactly like the one shown in Fig. 201, the Aures lock can be made altogether of wood. But with this lock, as described below, metal springs were used (Figs. 219, 220, and 221).
