A ORNEYS NETE ELMER E. NEAL, OF LANGI-IORNE, PENNSYLVANIA, ASSIGNOR TO PEERLESS HANID- i CUFF COMPANY, OF SPRINGFIELD, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS.
HANIDCUFF-LOCK CONSTRUCTION.
Application filed September 12, 1922. Serial No. 58?,723.
T 0 all whomt't may concern:
Be it known that I, ELMER E. NEAL, a citizen of the United States, residing at Langherne, in the county of Bucks and State of Pennsylvania, have invented new and useful Improvements in Handcuff-Lock Construction, of which the following is a specification.
The present invention relates particularly to lock constructions for handcuffs or the like although it is capable of embodiment in look constructions of other types.
The object of the invention is to improve lock constructions of the general character above indicated for the purpose of positively insuring against any possibility of picking the lock.
To the accomplishment of this object the invention consists in the features of construction and in the combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.
The invention will be explained in connection with the accompanying drawings illustrating what is at present considered to be the preferred form of the invention.
In the drawings:
Fig. 1 is a view, in side elevation, of a handcuif in which the present invention is embodied 1 Fig. 2 is a top plan view of the handcufi shown in Fig. 1;
Fig. 3 is a detail side elevational view of a portion of the handcufi' shown in Fig. 1, disclosing particularly the locking mechanism, one of the face plates of the lock frame being removed to disclose the working parts;
Fig. 4 is a sectional view taken substan tially in the plane indicated by the line 4-4 of Fig. 3; and Fig. 5 is a View corresponding to a portion of Fi 3 but showing a modification of the invention.
The present invention is shown as e1nbodied in a lock construction comprising certain operating parts which are similar to corresponding parts disclosed in applicants copending application, Serial No. 552,254, filed April 13, 1922, and assigned to the Peerless Handcuff Company of Springfield, Massachusetts. Although some of the features are not necessarily limited thereto,
the lock construction of the present invention is specifically adapted for use and is claimed in combination with a handcuff of the type shown in the application referred to. Consequently only a brief and general description of the handcufi its-elf and of the common features of the lock mechanisms will bogiven, reference being had to said application for a more detailed description, if desired.
Referring to Figs. 1 and 2 of the drawings, the handcuff therein shown comprises a solid'rotatable locking arm 1 which is curved to embrace one side of the wrist, and
a pair of parallel arms 2 and 3 which support the rotatable arm, 1 and are curved to embrace the other side of the wrist. The
locking arm 1 is pivoted upon a rivet 4t which oins one pair of corresponding ends of the parallel arms 2 and 3 and holds said arms spaced apart just far enough to allow the arm 1 to swing freely between them. The other pair of corresponding ends of the parallel arms 2 and 3 are enlarged to serve as face plates or covers 5 for a U-shaped lock frame 6 which is held in place by rivets 7 and serves, in conjunction with the face plates 5, to provide a recess within which the lock mechanism is housed. edge of the rotatable arm 1 is toothed, as indicated at 8, the teeth extending for a considerable distance from the free extremity of the arm and being adapted to cooperate with locking mechanism in the do scribed recess. The arm 1 is further provided at each side with a groove 9, these grooves being on arcs struck from the pivot center of the arm 1 and being adapted to receive rigid posts 10 on the face plates 5 which serve to prevent the arm 1 from being pried inwardly when locked.
As heretofore constructed, the teeth on the rotatable arm were ratchet teeth such as shown in the drawings of the application The outer 1, while the ratchet teeth 32 are adapted to be engaged by the ratchet tooth 18" on the latch lever 20.
lVhile the locking mechanism has been herein illustrated and described as including the sliding bolt 25 which functions to effect the double locking of the handcufi", it should be understood that the use of such a member is not essential to the present invention, and that the construction of the lever 20 and the plungers 2 and 26 may be modified in various ways. It should further be clearly understood that this invention is not in any way limited to the use on the arm 1 and pinion 15 of teeth of the particular shape or type shown as in practice it may be found desirable to modify the form of these teeth more or less. The scope of the invention therefore is to be determined from the appended claims rather than from the foregoing description.
WVhat is claimed is 1. The combination in a handcufi' of two locking arms, one pivoted to the other and arranged to swing through a complete circle, a member located on the other arm and ro tatable about a fixed axis and adapted to be operatively engaged and positively rotated by said first arm during a part of the swinging movement of the latter, a latch normally operating to check the rotation of said member in one direction while allowing it to rotate freely in another direction, thereby locking said first arm against swinging movement in one direction only, and a casing enclosing said member and latch.
2. The combination in a handcufi' of two locking arms, one pivoted to the other, and arranged to swing through a complete circle, a toothed wheel located on the other arm and rotatable about a fixed axis, teeth on said first arm adapted to intermesh with the teeth of said wheel to rotate said wheel, and a latch engaging with the teeth of said wheel and operative to check the rotation of the wheel in one direction while allowing it to turn freely in another direction, thereby locking said first arm against swinging movement in one direction only and a casing enclosing said wheel and latch.
3. In a handculf, the combination of a fixed part, a locking means in said fixed part, and a toothed locking arm pivotally mounted on said fixed part in a manner whereby it may be revolved so as to be brought into or out of operative relation with said locking means by a continuous motion, said locking means comprising a latch, and a toothed wheel rotatable about a fixed axis between said latch and arm, the teeth of said wheel being adapted to intermesh with the teeth of said arm and also being engaged by said latch whereby said wheel and said arm are prevented from moving in one direction while they are permitted to move freely in another direction.
d. In a handcuff, the combination of a fixed part, a locking means in said fixed part, and a toothed locking arm pivotally mounted on said fixed part in a manner whereby it may be revolved so as to be brought into or out of operative relation with said locking means by a continuous motion, said locking means comprising a latch, a pinion interposed between said latch and arm and rotatable about a fixed axis, the teeth of said pinion being adapted to intermesh with the teeth of said arm, and ratchet teeth on said pinion engaged by said latch whereby said pinion and said arm are prevented from moving in one direction while they are permitted to move freely in another direction.
5. A look construction of the character described comprising, in combination, a movable member having teeth thereon, a toothed wheel for engagement with said member, a spring pressed latch for said wheel automatically operable to permit movement of said wheel in one direction but not in the opposite direction, means manually operable to hold the latch to lock said wheel against any movement and a lock casing to guard said latch within which said wheelis mounted on a fixed axis, and means in said casing providing access by a key to unlock the parts within and additional means to manually operate from without the casing the parts within the casing for a locking operation only.
6. A lock construction of the character described, comprising a movable member having teeth thereon, a toothed wheel for en gagement with said member, a latch for said wheel to automatically engage said wheel and prevent its movement in one direction only, a slidable bolt operable to hold said latch to present any movement of said wheel, a lock casing for the latch and bolt within which said wheel is mounted on a fixed axis, said casing having an opening in line with one end of the bolt whereby the latter may be moved to a functioning position.
7. A look construction of the character described comprising a movable member having teeth thereon, a toothed wheel for engagement with said member, a latch for said wheel to prevent movement of said wheel in one direction only, means movable to position to hold said latch for preventing any movement of said wheel, a casing for containing all the lock parts within its outer surface and providing access for manually positioning said means in addition to the use of a key.
In testimony whereof I have affixed my signature. 7
