UNTTED STATES PATENT Ormea LEWIS A. HAINES, OF WESTMINS'IER, MARYLAND.
IMPROVEMENT IN TIME-LOCKS.
Specification forming part of Letters Patent N o. 170,553, dated November 30, 1875 application filed ,n
October 16, 1875.
To all 'whom t may concern:
Be it known that I, LEWIS A. HAINES, of of Westminster, in the county of Carroll and State of Maryland have invented a new and valuable Improvement in Time-Locks; and I do hereby declare that the following is a full,
clear, and exact description ot' the construction and operation of the same, reference being had to the annexed drawings, making a part -ot' this specification, and to the letters and ligures of reference marked thereon.
Figure 1 ofthe drawings is a representation of a plan view of my lock, and Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a transverse vertical sectional view thereof', and Figs. 4, 5, 6, and 7 are detail views.
. This invention has relation to that class of locks commonly known as time locks, wherein the locking and unlocking of the bolts are effected automatically by means of one or more time-pieces inside of the lock-case. My object is mainly to simplify this class of locks, and to secure greater certainty in their operation, and also to provide a simple device wherebyr a person, after shutting the safe-door, and locking it by any of the well-known locks, can cause the bolts ofthe time-lock to be shut automatically at any hour he may desire, and to be unlocked at any predetermined hour.
l The nature of my invention consists mainly in two graduated dials, onel or both ot' which is actuated by watch mechanism, said dials having scores in their peripheries, which will at the proper time release a loaded arm, and allow one or more bolts to be unlocked by the turning of a cam-plate, as will be hereinafter explained.
The invention also consists in an auxiliary graduated dial, having a groove and notch in its face, in combination with a gravitatingarm, having a stud on one end adapted to be received in the circular groove in said dial, and having a hooked retainer on its pivoted end, which, with a stud onthecam-plate, will hold the bolts unlocked, and, at the expiration of a given time, will allow said bolts to be locked by the recoil of the said cam-plate, as will be understood from the following description.
In the annexed drawings, A designates the case of the lock, which may be made ot' any desired size, and in any suitable manner. This case A is separated into three compartments, a, al, and a2, and is provided with a door, A', which may have a transparent plate. B B1 designate two dials, the pe'ripheries of which are. in close relation to each other, and at b b scores are made in the same, as shown in Fig. 1. The faces of these dials are marked oft', and the marks numbered on each dial from 0 to 43, the numbers commencing and ending at the angles of the notches or scores. U C are two shafts, which pass through a bearing-plate, C', and have collars c c rigidly secured on them, against which collars the dials4 B Bl are firmly secured by means of milled nuts 0l d. The shafts will be suitably connected to watch mechanism applied inside ofthe compartment a, which may be wound up by inserting a key in a hole made through plate C', or through the back of the case A. It'desired,.the watch-movement may only be applied to one ot 4said shafts, C. Directly be low the dial B is a dial, B2, which is secured by a clamping-plate, e, and a nut, 1,011 ashat't, f, which passes through the plate C', and is actuated by watch mechanism, so as to make a complete rotation once in twelve hours. rIhe face of this dial has a'circular groove, g, in it, from which radiates a notch, g', and between the groove and the periphery of the dial are figures,corresponding to hours. D designates an arm, which is keyed on a shaft, E, and which has a weight, W, on one end, capable of oscillation about va stud, h. A removable pin, h', is passed through the weight, and is designed for sustaining the armI D in the position shown in Fig. 1, in which position pin I/ lies between and upon the two dials B B1. The shaft E passes loosely through a iixed plate, F, and a flanged circular camplate, G, and has keyed to it a circular'plate, Gr. The inner end ot' shaft E has its bearing in the back of the case A. The cam-plate G has a convolute spring, S, secured toit, which spring is wound around the shaft E, and secured to it so that by its recoil it will turni plate G in the direction indicated by the arrow in Fig. 1. The plates G and G' are constructed with shoulder-stops it' on their flanges, for the purpose of preventing the spring S from unwinding. The plate Ghas two curved slots, j j, through it, arranged on opposite sides ofthe shaft E, through which pins k k are passed, which pins connect two endwisesliding bolts, J J, to plate Gr, and causethis plate to shoot the bolts, and also to retract.
them. Instead of two bolts, a single one only may be used, in which case one ofthe curved slots, j, will be omitted. K designates an arm, which is pivoted at l to the plate F, and constructed with a hook, m, on this pivoted end, and a stud, n, on its free end. rllhe hook m is designed to engage with a stud, p, which rises from the plate G through a curved slot, r, made through the plate F. This engagement is madewhen the bolts J are retracted and thestud n is in the' `groove g in the dial B2, as indicated in dotted lines in Fig. 1. The
hooked arm K, when in the position last named, prevents the bolts from being shot, and when the dial B2 turns until the notch g is opposite the stud n, said arm will drop, release the stud p, and allow spring Sto shoot the bolts.
The lock is set for unlocking by adjusting the loaded arm D in the position shown in Fig. 1, and then, after loosening the nuts d d', setting the dials B B1 by the' nulnberson them, so that at the hour required to open the safe one or both notches b will allow the arm D to drop, and thus retract the bolts.
What I do claim as new, and desire to secure by Letters Patent, is-.
1. Graduated and numbered dials B B1, adjustable on shaftsG, and notched as described, in combination with weight W, pin h', arm D,
shaft E, plates Gr G', spring S, and one or more bolts, substantially as described.
2. The dial B2, grooved, notched, and graduated, in combination with the studdedand hooked arm K, and the pin p on yspringplate G, substantially as described. i,
3. In a time-lock, the circular plates Gr` G',
for the purposes described.
Y In testimony that I claim the above Ithave hereunto subscribed my name in the presence of two Witnesses.`
