This invention relates tof'impr'ovements in padlocks and is adapted. for use on? barns,

' .cated in a spaced relation garages, railroad car andthe like. y

An objectofmy invention is to provide a padlock having a shackle rigidly attached to,

or integral with, the lock casing, thereby forming the desired strength of construction.V Another feature of my invention is to pro'- f vide a Ashackle so designed as easily to engage two or more eye-bolts, haspsv orstaples lo-V o n .relatively separable elements. l

A further object of my invention is to p-rovide such a padlock which is inexpensive,

simple in construction and will not readily get out of o-rder.

My invention comprises further novel features, details of construction, rand combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Y Fig. 1 is a plan view ofthe padlockV in an unlocked' position, with the front pflateof the casing removed.

Fig. 2 is a fragmentary plan view of the lock mechanism in its unlocked position.

Fig. 3 isa fragmentary plan yview of the look mechanism illustrating the relative position of the key at the completionvof the locking movement. l

Fig. 4 illustratesthe lock in servicevwith the lock arm in closed bolts.

Referring to the drawing, in which similar numerals of reference indicate t-he same parts, the casing comprises a front plate 5, a back plate 6 anda side member i' which are secured rigidly by rivets 8. A bolt 9 is slidably mounted in guide members 10 which are formed on plate 11, said plate being secured to the back plateV 6 by rivets 12. A pin 13 and a segment 14 are formed on the plate 11 to engage the key 15 and' are employed to resist the insertion 0f 'a foreign key. A curved spring catch 16 notched atone side is secured to the back plate 6 and engages a shouldered notch 17 formed in the boltl'9 when said bolt is in locked position. A U-shaped shackle 18 Vis secured at one side to the back plate 6 and the out-turnedends 19 of the side member 7 by means ofrivets 20 and' theother side of the shackle is adapted to be inserted through the eye bolts 21 and position between the eye 22 mounted in thedoors 23 and 24, andV pivot. j In the lockingfoperation, the shackleY 1 8 j d having been Vinserted ythroughthe eye-bolts k21;.an'd 22 and'then through a'holeji,inthe throughone end of alock arm 25'.'v lockv arm is vfree to Yswing on the shackle 18Jas`a arm25,the latter is swung to cause ac atchl V lug`2bV formed on thearin and itted"witl .3 boltfhole 27to be inserted through aslot 2844 -v `in the front plate 5. l/Vhenthe Vlmyfltis turned one revolutiomto asemi-locked posiition, an offsetV 29 thereon enga' es a lug B0 I and slides the bolt 9 through t e bolt hole 27 in the lock arm; The olfset29engages the Ylug 31 during a secondrevolution of the y key and moves the bolt 9 a step further,

' thereby permittingthespringcatch to snap into locked'position behind the shoulder of notch 17, thereby 16 and then to move the bolt 9, bymeans 'of v I causing vthe spring catch l 16 to secure the bolt. 7'

y The padlock is opened by turning the key 'reversely to the locking movement thereby causing the offset 29 to raise the spring catch open position,,thereby'releasing the lockv arm 25 to be'swungopen, whereupon thelock and shackle can be removed and the `door opened. GenerallyI prefer to placethe lock arm between the eye bolts, as shownin Fig. `V *Y 4l, as that arrangement uses the eye bolts to `hold the lock arm` against being tampered withon the shackle. K Although I have -described andillustrated a particular design, construction and, arrangement of parts, Ido not `wish to be lim-Y' ited thereto except as noted in theV appended;

claims. I

Having thus described inventiomwhat Iclaim as new andi desire to secure by Letters Patent, is

Y 1. A padlock comprising a lock casing f Y rigidly mounted on a Ufshapedshackle,iny 'Y 1,

combination with a lock arm having means to detachably mount it Vpivotally on the shackle,

and a boltin the casing and engaging 'theVV lock a-rm to secure the arm 1n locked Vposition Vonv the shackle, the shackle being adapted to s be inserted through elements secured to the several parts to be locked.

2. A padlock comprising a lock ying front and back plates and a marginal wall 'out-turned at its Vends and secured to saidV plate, a rigid U-shaped'shackle having one end secured tothe out-turned `portions off the marginal Wall,` 'the 'free leg 'of theTshackl'e being adapted to be inserted through retaining members in the elements to belockech and a lock arm removably and ivotally mounted on thefree leg of the shac (le and means c'oacting with the padlock to lockthe armin position on the free legof the shackle.

3. In a padlock, a lockrarm, a sliding bolt adapted to `engage the arin and having twoVV lugs and a lock shoulder7 a spring adapted tot interlock with the shoulder and having .its free end bent into positionadjacenttto the. lugs, said lugsbengso positionedthat a key having a notched actuator, in the first vrevolution thereof, engages one" Vbolt lug and moves the bolt toward locked position and by further rotation engages the seeondlug and moves the bolt to fully locked position,

and a single reverse rotation of the key disj- Vplaces the spring and fully unlocks the bolt,

substantially as described.

4. A padlock comprising aV lock mechanism, a lock casing, a 'Ll-shaped shackle rigidly attachedto the casing, a lock arm pivotally Vmounted 'on and removable from the free leg of the shackle, and means includ-V "Jed in the lock mechanism and adapted to Vengage the arm to lock the arm'against removal lfrom the shackle,A as and for the purposes described. Y v

5. A padlock according to claim 4, in Which the lock mechanism Ycomprises a sliding bolt SALVATORE SPANO.
