E. W. BRETTELL, OF NEVARK, NE\V JERSEY.
LO CK.
Specification of Letters Patent No. 28,828, dated June 26, 1860.
To all whom it may concern.'
Be it known that I, E. W. BRETTELL, of Newark, inthe county of Essex and State of New Jersey, have invented a new and useful Improvement in Locks; and I do hereby de- Clare tha-t the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l. is an internal View of an ordinary lock with my invention applied to it and bisected in the line ai, Fig. 2; Fig. 2 a section of ditto taken in the line y, y, Fig. l; Fig. 3 a detached longitudinal section of my invention taken in the line a, z, Fig. 1; Fig. 4 a detached longitudinal view taken in the line z, s', Fig. l; Fig. 5 a detached view of a yielding plate of ditto.
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to obtain a simple and efficient tumblerarrangement that may be applied to any ordinary lock to render the same, at a small additional cost, equally as burglar-proof as the more expensive kinds in general use.
The invention consists in placing a series of sliding tumblers within a rotating tube which is provided with a dog and tted within a case attached to the lock, and using in connection therewith a guard plate, all being arranged substantially as hereinafter described to effect the desired end.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, represents the case of an ordinary lock, B, the slide latch or bolt which may be provided at one side with a dog C, to be actuated by a knob D. D, is the spring which acts against the slide latch or bolt. If the knob D, be used, of course it is at the inner side of the door.
E, is a hollow cylinder which is attached to the case A of the lock said cylinder projecting out from the case A, at right angles. Within this cylinder E, there is fitted a tube F, which is allowed to turn freely in the cylinder when permitted and has a series of sliding tumblers b, placed within it, the tumblers being placed at each side of a stationary plate c, tted centrally within the tube F. This plate c, which serves as a partition, may be much thinner than the tumblers. The tumblers Zn, are wider than the tube F, and project through longitudinal slots d, in its sides and the inner parts of the tumblers are notched or serrated at their outer edges as shown at e, and provided with lateral slots f, at different points from their inner ends the use of which will be presently shown. Each tumbler b, is slotted longitudinally and a spiral spring g, is fitted in the slots, there being a spring g, at each side of the stationary plate c. Each spring lit-ting in the slots of two tumblers.
The outer end of the tube F, is slotted to allow a key G, to be passed into it said key being of thin plate having bits at one end of varying length corresponding to the varying distances of the slot f, from the inner ends of the tumblers. The key G, is shown on Fig. 2.
The inner end of the tube F, is fitted in a plate H, which has rods g, attached, said rods bearing against a flanch h, at the inner end of the cylinder E, the rods g', keep the plate H, a proper distance from the flanch z, and screws z', pass through the fianch 7L, into the rods g. A
I, is a plate which is fitted on the inner part of the tube F, and the rods g', g. This plate is notched at each side of its central opening y', through which the tube F, passes, as shown at 7c, 7c, see Fig. 4; Against the plate I, springs jx, bear which springs are placed on the rods g, g, and in the tube F, pieces of cork gx, are placed, which prevent a too free. movement of the tumblers and the notches 7c, allow the tumblers Z), to be pressed inward through the plate I, where said tumblers are acted upon or pressed in by the key G. On the inner end of the tube F, there is placed a dog J, which acts against the slide latch or bolt B, when the tube F, is turned.
From the above description it will be seen that if the tumblers I), be shoved inward without bringing the slots f, in line with each other and the plate I, the tube F, cannot be turned. In order therefore to turn the tube F, so that the dog J, may act upon the latch or bolt B, a key must be used having bits of varying lengths corresponding to the varying positions of the slots f, so that said slots may be brought in line with plate I, and the tube F, and tumblers turned and consequently the dog J.
If a wrong key be introduced into the end of the tube F, and the tumblers forced inward with a slight turning movement of the key the notches e, will catch the plate I,
and the latter will be forced inward with the tumblers b, as shown in blue Fig. 3. This movement of the plate I, prevents a burglar from ascertaining the position of the slots f, in the tumblers by obtaining a pressure of the tumblers against the plate I, a result which might be accomplished were the plate I stationary for in the latter case the tumblers might be operated separately and by that delicate sense of feeling which burglars acquire by practice ascertain the position of the slots f, in .each tumbler, but by having the plate I, arranged as described so as to yield under a pressure of the tumblers when wrongly dispersed by an improper key, all skill will be baffled in endeavoring to obtain a knowledge of the position of the slots f, by pressure or the sense of feeling.
I am aware that sliding tumblers provided with slots at varying points have been used and arranged 1n various ways 1n order to forni burglar proof. locks; but, I am not aware that a series of tumblers have ever been placed within a tube fitted within a E. W. BRETIELL.
