Patented Oct.A 25, 1910.

Application filed April 28, 1910, Serial No. 558,240.

To all whom 'it may concern:

Be it known that we, Gnonon M. MILLER and SAMUEL R. SLAYMAKER, citizens of the United States, residing at Lancaster, in the county'of Lancasterand State of Pennsylvania, have invented certain new and useful Improvements in Padlocks, of which the following is a specification, reference being had therein to the Iaccompanying drawing.

This invention relates to a self-locking padlock, and more particularly to that class of padlock in which the shackle-locking mechanism is constructed with a positive action and not a resilient action depending upon springs. y

The objects of the invention are to so construct a lock of this type that it shall embody a simple, positive and durable mechanism, composed of few parts, and proof against accidental opening caused by vjarrin.

l VITith these and other objects in view,.our

invent-ion consists in certainnovel construction andl combination of parts as will be hereinafter fully described and claimedgand. illustrated inthe accompanying drawings, whic-h form a part 'of this application, and in-whichlike figuresof reference .referfto corresponding parts in all of the views; but

it is fully understood that while we have herewith described our invention as shown, thatwedonot conneourselves to the-exact designpasf shown, as slight; changes ;may.. b,e, Inadewithin the scope oftlie claims with?,

outdepartingirom thesp'irit of the in -v vention.

pivoted within the ,case andp rovide d with a projectlngstud, a series of key tumblers. for-engaging andi locking said dog, .akey actuated sli ing unlockingyplate [for erigaging .the Astud of the dog-.and ,forcing the dog out of engagement with the sha. ck le,and. a spring actuated, stop slideyl fon limiting the acties, .ef open position. In the drawingsz-Figu-re 1, is 'La' front View of the lock, .Withf the` c oyer plate removed and showing the mechanism in a locked position. Fig. 2, is asimilar View,

the .dqgfwhenftheflock is in an but showing the position of the mechanism when the look and the shackle are open. Fig. 3, is a transverse vertical sectional view through the center oit' the lock. Fig. 4, is a perspective view of the lock lremoved from the casing and separated.

y The lock is constructed witha twopart casing, comprising the shell -or case .1, hav.-

ing the sidewalls 2, which are cut away to admit the ends of the shackle, and the cover 3, which is retained by riveting the projjecting ends of the, various studs and pins which project therethrough.

The shackle 4, is lformed with, the enlarged pivot end 5, which is mounted upon the pivot post .6, and normally held in an lopen position by the actuating spring 7, which `is also mounted upon said post 6, with one of its ends engaging the side 8, l.

of a recessedvportion of said pivot end 5, and the other end of said spring 7, engaged l byfa4 clip 9, vwhich is integral. with the case l' 1; while the other .eI-1d of said-shackle 4, is for-med with the hooked nose -10,and the shoulder stops 11, and 12, which abut l, against the. recesses 13, and 14, in the Acase wall 2, to prevent the, nose of the shackle 4, v-l rom'entering'too far into` the case 1'. t' The shackle-engaging dogv 1 5, is; pivoted ,1 upon the pivot stud; 1.6', andis formed with the shackle-engaging hook; 1 7, the shackle Inose-bearing surface 18, the catch point 19, thetumblenengaginglug120, and the stud 21, for engagement with the sliding locking plate.2 2. 1 1
