Application filed August 29, 1925. Serial No. 53,249.

' priated .Without unduly Vincreasing-the size of the padlock; that uses anoscillatnglor rocking key carrier; that comibinesv-w1th the key carrier a variably notched locking plate; that utilizes a sliding,r 'hasp which, in itsfunlocked position, may' be rotated on the axis of one of its members; and that is simple in construction and very effective in practice. A l f With these yand 'other ends in view, l illustrate in the accompanying,drawing such instances of adaptation as will shony the broad underlyingfeatures or niyinvention, Without limiting myself to the specific details show-n thereon or describedV hereiny Figure 1 is an elevation in section on line 1-1 of Fig. 2.V

Fig. 2 is an elevation in sectioninately on line 2 2 of Fig-l1. i f

'Fig'. 3 is a plan view in section online 3-3ofFig.-1. Y 'n 1 f Fig. 4 is a view similar tor'Fig. 1- showing a key in positionto unlock the hasp. Y

Fig. 5 is a side elevation partly in section. Fig. ris a detached velevation of the locking end ofthe hasp.

Fig. 7 is a perspective view-of .the lockapproxiing plate.

In practically carrying out my inventioi'l, I may use any desired form or shape of casing 1. Whatever the extent or shape of the easing is', it is supplied in'its front edge with a recess 21 to receive the short end 3 of the hasp 2. Another opening 8 is formedfrom the sanie'face and it extends almostthrough the casing 1 as shown in the figures of the drawing. This hole accomodates the long end Il of the hasp' 2. Another opening 22 is formed in the casing 1 from the lower This opening receives ing. In the right hand edge a small hole is made for the retaining pin 10 which serves to prevent the complete Withdrawal off therhasp 2 when it is in its=unlocked position, by reason of the fact that the front end of this pin engages a flattened V2. In'the left hand edge a series of four smalll holes are shown in which key contiene y comes face 9 offl the locking end lof the hasp operating limit Vpins Slide. V.The pins 2e.,

are commonly called drivers. They are ings in which the pins 24lslide are closed by p'lugs'-26. A companion group ot key pins '27 have radial sliding movement in the key carrier 18. This key carrierhas an endwise key groove or slot 19. 4The function of the pins 27 and drivers24 in relation to the notches .of the key 23 are `Well known and need not befurther described. 'The key carrier 18 is held inl place by a locking plate 11 which has slidingy movementV in the' transverse' slot 15.

ing plate 11. AV key engaging notch 13 is formed at the deepest portion of the notch 16. 'The other edge 14 of the notch 16 engages the vannular groove 20 `formed in the key carrier, While the'plate llris in cover17, as shown in Figs. 2, 3, and 5. The long end` 4 of the hasp 2 terminates in the end 6 formed beyond the locking groove4 5. It is constantly under the `pressure produced by the hasp spring 7, which spring serves to push the short end 3 ofthe hasp '2` out of the opening 21 tounlock the lock Whenpressed forvvard'by springs 25 and the open- A notch 16A is formed in the under 'edge of the lock-v ever the key 23 is turned.` to the left so that its upper edge will engage the notch 13 and thus pull the locking plate 11 out of the groove 5.

the plate 11 is pressed against the head 6 ready to move into the groove5 when the hasp 2 is ,pressed down so that its'sho'rt end 3 is seated iny the opening 21, which effectually locks the hasp in positionuntil thekey is again turned to the left to remove the locking plate 11 from the groove 5. When As soon. as t-he key is removed, or even before if the spring 28 is strong enough,


the hasp Qis pushed endwise by the spring 7 until the short end 3 is removed from the opening 21, it can be rotated on the axis of the long end 4L so as to attachthe'hasp` whereever desired. Y

It is of course understood that'in addition v to the notches formed on the V`edge of the hasp slida'ble ina plurality of such openings and rotatable' inV one of them, a key carrier positioned in an opening formed in the' opposite edge of the casing said carrier having a lengthwise key receiving groove formed therein, an annular groove formedlin the long eud of the hasp, an annular groove in the key carrier, a notched lockiiig' plate movable transversely in the annular groove of the key carrier and adapted to simultaneously eng-age the annular groove of the hasp, and suitable springs for subjecting the hasp andthe locking plate'to pressure.

2. In padlocks, a ca'singLa hasp slidable and rotatable in the casinghaving an annular groove formed in its one end, a key Y carrier having an annular groove formed thereon, a locking plate adapted" to simultaneously engage the hasp and. the key carrier, a springk for pressing' the hasp in one direction,` a spring ,forl pressing the locking plate against the hasp, and means -for`moving the carrier on its axis tothereby shift the locking plate and release the hasp.

3. In padlocks, a casing, a. key carrier in the casing having a llengthwise groove formed therein to receivea key slidable in the groove, an annular groove formed on the carrier positioned between its ends, a notched locking plate' transversely movable in the annular groove of the carrier adapted 'to hold the key carrier positioned endwise in the casing,` and cooperating limiting means between the casing the key carrier and the key for freeing the carrier from the casing in order that it can be rotated on its axis at the same time that the locking plate is moved transversely of the carrier.

4e. In padlocks, a locking plate having a variable depth and width notch formed in Vits one side edge and a recess in one end, a

spring engaging pin projecting from the other end of the plate, a suitable casing having a recess to receive the plate, a spring for exerting pressure against the pin, a hasp movable in the casingfto cooperate with the recess, and a cover secured to the casing for holdingr the locking plate and associated parts in assembled relation.

5. In padlocks, a casing, a hasp slidable i and rotatable in the casing said hasp having an annular groove formed thereon, a key carrier, an annular groove formed in the carrier, locking means for simultaneously engaging the hasp and the key carrier,

means for pressing the hasp endwise, means `for engaging the locking means with the Y groove of the hasp, and meansVV for' moving the carrier on itsr axis to thereby shift the locking means out of engagement with the yhasp to free it for endwise movement.

In testimony whereof I affix my signature;
