Application May 4, ,1934, serialNo'. 723,8391/2 Y v 4' Claims.

My invention relates to a padlock of the type disclosed in my United States Patent Number 1,930,809, and issued October 17th, 1933.j

The object of the invention is to provide a padlock of the character described, which is simple in its construction and that maybe released without the use of a key. A

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, but it is to be understood that changes in the details of construction may be resorted l to that come within the scope of the claims hereunto appended. l l I In the drawing wherein like numerals rdesignate corresponding parts throughout the several views: Y

' Figure 1 is a vertical sectional viewof `a padlock constructed in accordance with the invention. I

Figure 2 is a sectional View on line 2-2, Figure `1. Y

Figure 3 is a bottom plan view of the ,'device, and Figure 4 is an enlarged transverse sectional view of the latching pin and associated latching spring.

Referring in detail to the drawing denotes an inner casing having an open lower end. A top plate 2 is permanently xed to the upper end of the inner casing. TheA latter is enclosed in an outer casing 3, which has an open upper end and a bottom 4. The inner and outer casings I and 3 are similar in contour, and the latter is telescopically shiftable on the former... The movelatter in any suitable manner. `A spiral spring 8 extends vertically in the center of the casings I and 3, and has its lower end secured, as at 9,

to the outer casing bottom 4. The upper end of` the spring 8 is attached to the bracket "I, as at I0. The action of the spring 8 normally forces the outer casing 3 to the closed position on the inner casing I, but allows said outer casing to be projected on said inner casing a. distance permitted 5 by the stop pin 5 in the slot 6.

f in the inner casing I and xed in position in the y (el. Tri-'10s) The top plate iisp'rovided with a pairof spaced openings, respectively indicated fat I I and I2, for the passage of the arms I3 and|4 of a shackle I 5.l The arm I4 is ofgreater-length than the short arm |3,-andgextendsthroughfthe.top plate aA opening |2 into `the innencasing |and through the lower end ofthe bracket'l. The short arm |3is free and'engages inthe top plate opening I I.

A-sleeve'fIG is xed on the long arm I4, within the inner casing and limits the Vertical move- .1.0 ment of theshackle I5,but allows the freeend ofthe short arm I3,to-clearthetop of the plate opening I I when the shackle |5` is released.

AV spiral spring I'I1is mounted onv the shackle arm III between the sleevey |6-and the lower end 15 `of ,the bracket '|.v .The A"action of the spring I1 vforces the shackle ating' bar is pivotally'connected,:as at|9,`to a ylug 2|! fixed inthe inner casing I Theother `end of the'operatingbaris' provided with a depending lip.25 Ito facilitatethe manipulation of the oper- '2.5 ating bar when releasing the shackle I5 inthe manner to be described. x

The operating bar I8 carries a fixed', laterally disposed locking pin 2|, which extends through an aperture 2z Vpropicien therefor adjacent tothe '30 t upper. end of. the bracket 1; The locking pin 2| engages the upper vend of the sleeve I6 and thereby secures 'the shackle |5`in the locked position. Aatrspring 23, carriedby the bracket 1, and

engaged in the operating. bar |8,=normally forces 35 the'locking pin.2|.to the locking position. ment of the outer casing on the .inner casing is 'The inner casing 1| is4 provided, with va. large' opening 24 -to allow access totheflip 25 for shiftingthe operating bar:` I8fto.the :releasing position. L 2;.` y f $0 A vertically disposed latching pin 26 is revolubly mounted in a supporting bracket 21 xed to the outer casing bottom 4. The latching pin extends through the latter and carries Aa xed knurled head 28, which is positioned flatly against 4*) the outer surface of the outer casing bottom. The latching pin is provided with a circumferentially extending cam groove 29, in which engages the concaved free end 3U of the horizontal arm 3| of a flat spring catch 32. The latter is fixed to and depends from the top plate 2.

As shown in Figure 4, the formation of the cam slot 29 is such whereby the rotation of the latching pin 26 to one position will cause the r catch end 30 to clear said cam slot. The en- "5 gagement of the end 3U in the cam slot will secure the casings I and 3 together until the latching pin is rotated to the position clearing said end from the cam slot. A spiral spring 33 is mounted on the latching pin 26 and has one end fixed to the latter, while the other end thereof is fixed to the casing bottom 4. The action of the spring 33 always returns and maintains the latching pin in the securing position.

The latching pinfhead 28 isv provided with a teat 34, which is positioned at a predetermined point relatively to the clearance position of the latch-VV teat 34 with respect to thel clearance position of' the latching pin.

The outer casing bottom 4 may be provided with a keyhole slot 35- fort'he' purpose of confusing an unautlioi'ized attemptto operate the padlock to release the shackle IB,

InV practice the operation of my improved padlock is as follows: Assuming that all parte ofthe device are iri the positions `r,s'iliovvn in Figure l, the mening pin 2C is turned" 'to thefeiearance position and held in thisv latter 'position while theo'uter easing' is piilled downwardly to exposei-,iie open-ing ze in the :inner casing l. The operatin'gbar I Il` is new shifted until thelocking pin ZI clears the' sleeve I'Ii` to releasethe shackle I5. The latter Willi novi be'shitted' eilt- Wardl'y bythe tiox'i of the spring' II iintil the sleeve I8 abut's against the top plate 2' and the free end of the shackle arm I3 clears'- the: associated top plate 'o'r'i'ening-l It. The shackle! ISI'i's then free to be swung laterally to effect its removal. When the outer casing 31s -released:` the end' 30 of the spring catch, 32 will automatically engage the latching pin 2e and the saidrouter casing will be drawn tof the elosedy position bythe action of the spring o. To secure the shackle I5 the latter' needE only be forced: downwardly through` the top` openings It I' and I untilth locking pin ZI engages the topl oi. the sleeve It, 'as illustrated in Figure 1.

What I claim is:v

1. I'n combination, a padlock comprising, an inner casing', a top plate 'xedi tothe upper end of said inner casing' and' providedY with a pair. of spaced apertures, a shackle includ-ing' a pair of karms normally extending through' saidf apertures latter to permit access to said'locking element,

and means for securing'said outer'casing against movement on said inner casing.
