UNITED STATES A'rnN'r OrFIoE.
DANIEL T. BROW'N, OF PLAINFIELD, NEW JERSEY, ASSIGNOR TO JAMES H. MOWILLIAMS, OF NEV YORK CITY.
IMPROVEMENT IN PADLGCKS.
Specification forming part of Letters Patent No. 116,544, dated July 4, 1871.
To all ulwm it may concern.:
Be it known that I, DANIEL T. BROWN, of Plainiield, in the county ot' Union and State of New Jersey, have invented an Improvement in Padlocks; and the following is declared to be a correct description thereof: This invention relates to a compound swinging tumbler that g asps the movin g end of the shackle, said tumbler being blocked in such a manner that blow on the case will not relieve the tumbler from its hold upon the shackle. The compound tumbler is made ot' two parts, the iirst of which swings upon a ixed stud, and the seeond part swings upon the iirst, and the two grasp the end of t-he shackle somewhat like a pair of nippers.
In the drawing, Figure l is an elevation of the look with the cap-plate removed. Fig. 2 is a similar view, the ha sp being thrown back and the tumblers turned by the key; and Fig. 3 is a plan of the secondary tumbler. Fig. 4 is an elevation of a variation in the form of this compound tumbler.
The ease a and shackle Z) are of any usual size or shape, and a sprin g, c, may be usedto act again st the swinging end of the shackle and throw it out of the case when the tumblers rela-X their hold. The primary tumbler d swings upon the stud e, and has a talon, 2, to enter a mortise in the shackle and hold the same. The secondary tumbler h swings upon the stud or joint 3 upon the tumbler d, and the spring i' acts between the primary and secondary tumblers to draw the talons 2 and 4 toward each other. Vhen the lock is locked, the end 5 of the tumber h rests against and upon the stud 6, so that the tumbler cannot be thrown back by a blow upon the case ofthe lock. When the lock is to be opened, the key l is introduced and turned upon the stud 7 and lifts up the tumbler It to unhook the talon 4, and then the further movement of the key moves both tumblers and swings the tumblers upon the stud e until the talons 2 and 4 are clear of the end of the shackle. The foot-piece 'm of the tumbler d extends around below the key-hole as a guard, and carries at its end projections that act as wards to the key.
It will now be apparent that the prima-ry and secondary tumblers form a compound tumbler, resembling a pair of nippers, and that these tumblers swing in opposite directions, and that the secondary tumbler has to swing belore the pri mary one can be moved; hence thereis great security against the lock being opened by any extrancous means.
All the part-s of this lock are easily constructed, and hence cheaply made.`
In Fig. 4 the before-described parts are shown in a slight]y-diiierent shape, and the letters ofreference indicate the same parts, but instead of dependin upon the tumbler L d 1awing back theprimary tumbler r1, I make use of the portion d. of said tumbler r1 for the key to act against and insure the correct movement of the said primary tumbler. The stud 6 is located so that it blocks the tumblers it' any attempt ismade to open the lock by concussion or by apick, because the tumbler h has to be raised exactly to the point where the notch S at its end will pass back over the stud 6 before the lock can be opened. The hole in h for the joint-pin 3 is elongated to allow an endwise movement of the secondary tumbler IL as the parts 2 and 4 are separated by the forcing in of the end of the shackle b.
I claim as my invention- The hook-ended tumblers d L, crossing each other and hinged together atf3, and swinging upon the stud e, the parts being arranged and acting substantially as specified.
Signed this 19th day of January, A. D. 1871.
DANIEL T. BROWN.
