The lower end of the bar18 terminates in substantially the same plane with the correspending end of the rod 16, and they said bar extends through an arcuatel slet 22 in the base of the lock casing. A disk or thumb the rod and bar 16 and 18 respectively,land

this disk is preferably of'a diameter greater" th of the base of the lock casing than the wi The lowermosty end of the ubolt 12 is provided with a pair of outwardly projectingspace studs 24, between which the bar 18 extendsfand itv is apparent the foregoing description `that. upon rotatin thethumb disk '23,1 the frame 15 will oscillt bolt 12 to move accordingly. This move- 4ment will cause the prong 14 to move into or out of locking engagement with the shackle oscillation o the frame 15. v Pivoted at its inner end as at` to theV voutermost extremity of the arm 19 is a lever 26.y This lever extends through a Vhollow portion formed adjacent the outer yend of the arm 20, and protrudes at its lower end through an arcuate slot 27 formed in the base ofthe lock casing.' `It will be observed that this lever is disposed normally in spaced parallel relation to both the rod 16 and bar to the said bar. A vspri 28`normally crees the lever outwardly, an the extremities of 40 limit of 'its rotation inv one direction, the

lever 26` under impulse ofthe sprin 28 will engage adjacent its Iowermost en within one or the other of the'notches 29 and 30.4

The iframe will v then be locked either in locking or unlocking position as is obvious.

In addition `to the rotary or oscillatory movement required for moving the locking rbelt to operative or inoperativeposition, sliding 'orlongitudinal movement is essenis adapted,mwhen the frameis moved to the Y limit of its inward movement, to engage behind an youtwardly projecting member or arm' 31 on the upper end of the locking bolt 12. When'in this position, see Fig. 2, it is v obvious that oscillatory movement of 'the y frame can not operate to retract the lockprong. This ysliding movement ofthe` is caused by exerting either inward o r outwardpressure upon the thumb ds'k 23, and a spring 32 carried by the central shaft or, rod 1 6 yieldabiy maintains the said rod v in either inward` or outward position. It be' observed, litieularlyr with reference tom-Sofs wheel 23 is connected to the lower ends of.,

. position.

' In operation, assuming the parts'tobe in 70 "locked position, as shown in Figsrl andv 2,

the disk 23 is pulled outwardly.y The tension of the spring 32 is such as will retard the frame against ready movement but may be easily `overcome byl exerting suilicientpressure. When 'moved to. the position shown in Fig'.r3, the innermost, end of the rod 16 will be' withdrawn .from'the path of 'l travel the arm k31 at the uppermost end of thelock bolt, and rotary movement vapplied tothe frame through theJ thumb disk 23 vwill 'rockfthe saidbolt to withdraw the spring le fromv enga ment with theV free end ofthe'shackle 9. owever, the frame is locked against rotation by reason of the spring pressed lever 26 being engaged within thenotch 30. It is therefore' necessary to depress thelowermost end of the lever 26 to disengage the same from the notchy 30, whereupon theiframevmay'be oseillated So as to rock the bolt A12 to withdraw the prong 14 from engagement with the shackle end; When the frame has been turned to the'lilnit of, its releasing movement, the lever 26 will slot 27","and should-it'be desired to prevent tampering with the lock when thus unlocked, inward pressure applied to the disk 2,3 will causethe frame to move inwardlyi so Vthat the extremity'of the rod 16 will lock 100 behind the arm l81 but prevent swinging'y movement of thev Vlock bolt.

v From the foregoing, it is obvious that I have provided an extremely simple and yet thoroughly eilicient 'keyless lock. It will be observed, particularly with reference to Fi 4 of the drawin that a slot is provided 1n Y ortion of the disk 23, but this slot is noth ng Hmore thana dummy `or pering with' the lock into believing the lock to beone ofthe key actuated class.

While' the Vpresent disclosure is thatl Vof n what Ibelieve tobe theV preferred emboditial. The inner end of the'shaft or rod 16 ment of the invention, it 1s to be Vunderstood that the invention is not limited thereto, but that various changes maybe made in the construction, arrangementV and proportion of'parts-,without departing from the spirit o'f the invention, a's' defined in the appended claims.
