Definitions
- Figure l denotes an el evation of the said lock, portions of the cover or top plate being exhibited as removed from the case in order to more clearly represent some ofthe operative parts.
- Fig. 2 is a trans verse section of the lock taken through the handle and bolt.
- Fig. 3 is a vertical cross-section taken through the key-recess.
- Fig. 4 is a view of the lock as it would appear if the handle and its supporting-plate were removed from over the tumblers and main bolt.
- Fig. 5 is a view of the lower side of the supportingplate and the cam, through the aid of which the dog of the bolt is raised and the main bolt moved forward and backward, as occasion may require.
- A represents the metallic case of the lock.
- B is the main bolt, which in this instance is ⁇ composed 'of asti-aight bar, a, three studs, b b b,
- said main bolt has also a stud,'D, projected from it, and arranged so'as to operate in connection with a system of five or any other suitable nnmber of tumbl ers or slotted levers, E E,
- Each of said levers or tumblers turns on a fulcrum or pin, F, and is forced upward by a spring, G, properly applied to it.
- Each lever or tumbler has a long slot or opening, d, made in its front end and adjacent to the stud I), and
- the main bolt has a dog lever or tumbler, G', applied to it and made to work in a recess or depression, H, of the bolt.
- the said dog turns on a fulerum or pin, I, and has a stud, K, projecting from it and through an opening, K, made through the part M ot the bolt.
- Asprin g, 1N is applied to the dog and bolt in such a man toward the in the said dog, as seen in Fig. 4.
- the said recess is intended to act in connection with a pin, P, made to project upward from the case of the lock and through a long slot, Q, made through vthe main bolt, as represented in Fig. 4 by dotted lines.
- the dog G takes the position denoted in Fig. 4-that is to say, its rear end comes directly in front of the pin P, so as to prevent the bolt from being receded or moved back until the dog is elevated above the pin, so when the bolt isthrown back the recess O receives the pin P and prevents the bolt from being moved forward until the dog is raised so as to carry the said recess above the pin.
- the elevation of the dog is effected by a cam, R, (see Fig.
- Afxed to the plate U is a hardened-steel cylinder, V, which is of sufficient length to pass entirely or nearly through the door to eral slots, d, of the tumblers are arranged in their respective tumblers or in relation to one which the lock is to be attached.
- the outer end or part of said cylinder is formed with a circular depression of sufcient'size to receive a ner as to so operate on the dog as to press it part M.
- hardened-steel plate,W which is circular, with the exceptionA of a small segment takenfrom one side of it, as seen in the drawings.
- the said plate isattached to the shankl of the handle or to the handle itself, and moves with said handle and shank.
- the cylindrical projection V has an elon gated recess, X, made in it, as seen in Figs. 1, 2, and 3. From the bottom of the said recess and through the cylinder and its supportingplate, and directly over the system of tumblers or levers E, E, Ste., holes are bored of proper size tovreceive small pins, wires, or rods e e e 85e., there being the same number of said holes as there are tumblers, or, in other words, there being one hole and one pinto each ot' the tumblers. Each pin rests upon one of the tumblers. The several pins should be so adapted to their respective holes as to slide freely up and down in or through/the same.
- Each piny has a head, f, which prevents it from being drawn through and out of the hole in a direction outwardly.
- the several pins, the thickness of the cylinder and that of its sustaining-plate, and the extent of movement of the several tumblers should be so regulated that any one pin, when pressed downward inV its hole Vuntil the tumblers of it reaches its lowest point of depression, shall not pass entirely out of the hole it moves in, the hole being made to steady the pin and always keep it in place.
- the recess X I term the key-recess, its object being to receive the bar or part g of the key Y, a side view of said key being represented in Fig. 6 and a bottom View in Fig. 7.
- the said key is composed of the bar g and several small pins, h h, Ste., of different lengths extended from the same and at right angles to it, as seen in Fig. 6.
- Each pin h belongs to one of the pins e e, 85e., before described, and it should be of a length suiicient, when the key is'plaeed in the Vkey-recess and forced down, so as to depress the rods c e, 85e., and their tumblers to depress its pin, and consequently the tumbler thereof, to the depth required to enable the stud D of the bolt to pass into the slot d of the tumbler.
- the handle When the key Y is pressed into the keyrecess, the handle may be turned so as to cause the plate W to pass over and cover the key and keep it in place, while the handle is farther turned suliiciently to produce a reces sion of the bolt.
- the plate W as applied to the handle and made to revolve with it, maybe considered as auxiliaryto my main improvement or invention, as a lock may be constructed without such a plate, the handle, its shank, and cam being used to move the bolt, while the tumblers may he kept down by the key held in place ⁇ by any other suitable means.
- I however, consider the'saidplate W as a very important addition, as it will be seen that when said? plate is used in the manner hereinabove described it is impossible to throw the bolt back until the key and its recess have been completely covered by said plate. Colisequently, the difficulty of succeeding in any attempt to pick the lock by using any means other than the key itself, or an exact counterpart of it, willbe obvious.
- Z, Fig. 5,' is a pin or stud projecting from the plate U.
- the cam strikes against said -studI in order to limit the movements of the handle and its plate YV.
