LOCK.

Specification of Letters Patent. Patented Oct. 18, 1910.

Application filed January 19, 1909. Serial No. 473,052.

T 0 all whom it may concern:

Be it known that 1, CHARLES E. J OI-INSO-N, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Lock, of which the following is a specification.

My invention relates more especially to that class of locks knownas padlocks, and the object of the invention, generally speaking, is to provide a lock having numerous novel features of advantage and utility.

One form of device embodying my invention and in the use of which the objects above generally set out together with various objects may be attained is illustrated in the accompanying drawings, in which all of the views with the exception of Figures 11 and 12 are perspective views,Fig. 1 illustrating one section of the lock case; Fig. 2 illustrating the other section of the lock case together with the balance of the lock structure; Fig. 3 illustrating the other section of the lock case in which the other section of the container and the lock mechanism is located; Fig. 4 illustrating one section of the container; Fig. 5 illustrating the other section of the container; Fig. 6 illustrating the other section of the case; Fig. 7 illustrating the bolt and actuator; Fig. 8 illustrating the opener pin; Fig. 9 illustrating the opener spring; Fig. 10 illustrating the key center, and Fig. 11 illustrating the key.

Heretofore a common construction of locks of this class embodied a case formed as by casting, to which case the parts composing the lock mechanism were directly secured. The present invention differs from such prior structures in that a case or shell is provided which incloses a container to which the parts composing the lock mechanism are directly attached. This construction provides an extremely durable lock and one that may be readily formed for the reception of the operative parts of the mechanism.

In the accompanying drawings the numerals l516 indicate the sections of the lock case and 1718 the sections of the container. The case sections are preferably struck up to proper shape from sheet metal in dies and l1fl"ll1g ends and sides to inclose the container, one sect-ion as 15 having recesses 19 for the reception of dowels or lugs 20 on the other section of the case. A part of these recesses and the dowels to engage therein are formed on the side portions of the case sections, and a portion of said recesses and dowels on the ends of the case sections. This location and arrangement of the recesses and dowels on the sides and ends of the case effectually secures the sections against sliding movement one upon the other, the two sections being held from separation as by means of pins or like parts secured in holes 21 in the case. The con tainer is formed as from a bar of metal of a shape in cross-section the same as that generally of the container when it is assembled in the case. A piece of proper length is cut from the bar and one end of this piece is shaped to fit the bow end of the case. The opposite end of the piece is bored and counterbored, forming a recess 22 for the reception of a key center 23. Holes are bored for the reception of the various pins for securing the case sections 15 and 16 together and also upon which to pivot the bow 24. A lengthwise opening is then formed through the base, constituting when the parts are assembled a key chamber onehalf 25 of which is located in each section of the container, this opening being of a width equal to the distance between the ends of the wards 26 of the greatest length, and the opposite side of the opening. A crosswise opening is also formed through the piece at one end of the lengthwise opening, this crosswise opening, when the parts are assembled, constituting an actuator chamber one-half 27 of which is located in each section. The piece is then split lengthwise, as by a saw, forming two sections 1718 of the container. The meeting faces of t-hetwo sections are now further out to form recesses for the ends of the how 24, a bolt 28 and an opener pin and spring 29 and 30 respectively. The wards 26 are formed as by means of a gang of saws, as primarily formed they being all of the same length and after formation such number as may be desired being broken off to the shorter length to fit any desired pattern of key.

The bolt 28 is pivotally mounted upon one of the pins which hold the sections against separation, one end of the bolt being formed to engage in the usual manner the end of the bow 24 to hold it closed and the opposite end of the bolt having a foot 31 upon which the opener spring 80 is seated, the opposite end of the spring containing the opener pin 29, the head of which is in position to press against the end of the bow 24.

An actuator 32 is located in the actuator chamber 27, this actuator having a finger engaging a recess 34: (see dotted lines Fig. 10) in the bolt 28. The actuator also has a lug 35 which by contact with the end of the actuator chamber serves to prevent backward movement of the actuator under certain conditions, and thus prevent operation of the lock other than by regular methods. A spring 36 is employed to hold the actuator at one limit of its play. A key opening is formed through this actuator, within which the bits of a key engage. This opening is formed with a shoulder 37. Upon opposite edges of the key 38 bits 39 are formed, preferably the same on each edge. In the operation of the device, as one of the end bits 39 engages with the bottom wall 40 of the key recess in the actuator, the actuator is moved, carrying the lug 35 out of line with the end -11 and into line with a recess 42 formed thereunder. \Vhen the actuator has reached this position the ward on the op posite edge of the key engages the shoulder 37, moving the actuator backward, this movement, by engagement of the finger 83 with the recess 3%, swinging the bolt 28 on its pivot and disengaging it from the bow 24:, allowing the latter to be forced outward by means of the opener pin and spring 29 and 30.

It will be noted that the actuator is placed loosely in the actuator chamber, that is, it is not held by pivots or other attaching means. The spring 36 holds the lug 35 opposite the end wall 41 of the actuator chamber, so that a key or similar article is required to locate the lug in such position that the actuator may be thrown back to operate the bolt. This prevents any unauthorized operation of the lock mechanism as by means of a sudden jar caused by rapping the lock on one edge to throw the actuator or by other means.

lVhile I have shown and described herein one form and arrangement of mechanism for accomplishing the purpose desired, it will be understood that the invention is not limited to devices constructed in exact accordance with those herein shown, but that this arrangement and construction may be departed from to a greater or lesser extent without avoiding the invention.

lVhile the container is described herein as formed from a bar of metal, I do not confine the invention to such construction, as the sections composing the container may be formed from metal cast to shape if this method of construction shall be deemed most expedient.
