"comma (o1. ro se) object is the provision of such a padlock which aifords great security, and which allows location. of the locking and other mechanical parts in a manner rendering them virtually. inaccessible to moisture andother foreign elements which might interfere with their operation, despite the provision ofno special protecting means therefor.

Another object is the provision of an improved padlock having a body comprising a pair of relatively massive slidable portions carrying cooperating shackle-forming sections, and in which the shackle so formed, when locked, is secured at both ends against twisting.

rther objects and advantages will be apparent from the following description wherein referonce is made to the'accompanying drawing illustrating a preferred embodiment of my invention' and wherein similar reference numerals designate similar parts throughout'the several views.

In the drawing: Figure 1 is a view principally in sectional elevation, but partly in side elevation, of a lock incorporating the principles of this invention, showing the same closed. 7 Figure 2 is a similar view showing the lock partly opened, a greater proportion thereof being illustrated in side elevation.

Figure 3 is an end elevational view of the lock in closed position, partly broken away; Figure 4 is a bottom view of the lock, and Figure 5 is a detailed perspective view of the lock cylinder and bolt assembly.

Referring now to the drawing it will be seen that the lock consists of two principal parts,

iii, l5, longitudinally slidable with relation to each other. The portion H3 carries the principal shackle portion 52, which comprises a partly circular inverted hooksection, while the portion 15 is cooperatively formed at its upper end to complete the circular shackle opening, 'and slidable downwardly to free the 'end of the shackle hook, which isprovided with a lug portion ll adapted to fit into a recess It in top of the downwardly slidable block-like body portion P5.

The plane of cleavage between the cooperating body portions lQ-ltiis designated 20, anda dovetailed connection is provided between the parts, a headed tongueportion as It carried by portion [5 being slidable in a conformably in body la A spring 21 trapped in the faceof the; lock bolt forsuch purpose. lock cylinder is of course rotatable by means of a ,key (not shown), and the bolt, until member.

trapped in aligned openings in the tongue" shapedaperture in the body portion iii; A spring section 55 and in the body section directly thereabove, urges the block portion l5 downwardly to free the end of the shackle hookwhen the 1 lockbolt 25 is retracted to permit-such sliding" inovement. The bolt is laterally slidable in block i5into and out of engagement with an opening block iii behind the lock bolt tends 'to project the bolt, which is retractable by means of a lock cylinder it provided with an eccentric pin 3i engaging a slot .25 provided in the bottom .The

it is released in the manner described, holds the block portion it in'the lockedposition shown in Figure l, in which it closes the end of the shackle. A pin 33 projecting through the side of the body and into. a slot 36 in the tongue portion Q It limits the sliding movement of the parts. WhatIclaim i'sz. i 1. A padlock comprising a body formed in two sections slidable with relation to each otherupon a plane of cleavage extending longitudinally of, the midpo'rtion of the body, ashackle portion I rigidly carried by one of said sections, thef'other section being slidable to openand close said-p shackle portion, means. slidably connecting said sections comprising interfitting overengaging guide portionsQqne projecting laterally from one section and the other hollowed in the. other seca;

tion, said guide portions being located upon "one side of said plahe of cleavage and extending only part of the length of the body and-stowping short orthe shackled portion thereof, and l means for locking said sections against relative sliding movement, comprising a bolt member. mounted in one of said sections and movable across the plane of cleavage into "andfout of holding engagement lwiththe other section in the space between the guide portions andthe shackle portion; key-controlled operating means for said bolt member. including a lock cylinder' arranged upon the other side of said plane of cleavage'from' said interfitting guide portions 2; Means as set forth in claim 1, in which said bolt member is mounted transversely. in and near thetop of saidsection which. is movable toopen and close the shackle portion, said lock cylinder being mounted in said same section-parallel to said plane of cleavage (and below the bolt CHARLES NEI-ILS.
