Show FASTENING THE HEAVY DOOR Catches Described Herewith Will Hold Fait and Prevent Warping How Working Parts Are Made. ny J. W. OKIKKIV.) To prevent a door from being blown about by heavy winds, there should be a fastening at the top and one near the bottom. A hook at the top and a chain at the bottom looks like life In the primitive age. The fastenings herewith described are those that will stay fastened, and they will prevent the door warping, swinging out at tho top or bottom, and will catch every time the door is closed. The six pieces that-hold the working work-ing parts to the door are made of heavy hoop iron, bent in tho shape as shown in the small drawing at (A), y -rrrT , rrrT-r-rrT-rir Fattening for Heavy Doors. and are fastened to the door by nails or screws. The dotted lines show the position of the working parts when the tumblers are buck so that tho door may be opened. (I!) A coil spring that holds the tumblers in a closed position. The edge of the door Jamb where the tumblers rub as they paws to tho sockets, are beveled bo that there will be ihe least possible opposition to them entering. The notches at (C) are oblong, that the pins that work in them may not bind, as the tumblers are withdrawn. The dotted lines at (D) represent a notch that in in the door, through which the pin moves when the door Is unlatched. At (E) there Is a piece one-eighth of inch thicker than tho tumblers and the pieces that are marked (C); this permits the tumblers to move easily. There is used three-elghtbslnch bolts at (E) to bolt piece (C) to the door, and short bolt of the same size at (F) with the heads next to tho door. These bolts work loosely In the boles made in piece (C). All working parts work Just looso enough to move w ithout rubbing hard, but not so loose that there will be any rattling on the door by the wind. To open the door, the pin (D) is pushed toward the edge of the door, and as soon as released, the tumblers retain their former position, and whCS the door is shut, the tumblers will slip in place and hold the door secure. |
