PADLOCK.

SPECIFICATION forming part of Letters Patent No. 348,521, dated August 31, 1886l Application filed April 29,1886. Serial No. 200.507. (Modeln To @ZZ whom, it may concern:

Be it known that I, LoUrs HILLEBRAND, a citizen of the United States, residing in the city and countyT of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Padlocks, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l represents a vertical section of a padlock embodying my invention, in line a: x, Fig. 3. Fig. 2 represents a horizontal section, showing` the bolt and tumbler in unlocked position, in line yy, Fig. l. Fig. 3 represents a horizontal section, showing the bolt and tumbler in locked position, in line y y, Fig. 1. Fig. 4 represents a face view of the lock-cover or bottom plate. Figs. 5, G, and 7 represent views, respectively, of the bolt with a`housing-plate and the bolt with a key-ward plate and the tumbler. Fig. 8 represents a view of a key that may be employed.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a padlock of the order of a Scandinaviam7 having a bolt whose body has narrow arms projecting from the periphery thereof, whereby the thickness of the ease vis materially reduced, this provision also adapting locks to be formed of an increased width without increasing the thickness of the lock-case.

It also consists in providing the bolt with a tumbler which in locked position engages with the wall of the case.

Referring to the drawings, A represents the lockcase oi' a Scandinavian padlock,and B the shackle thereof. Crepresents partially-rotatable bolts, which are formed of ilat plates of metal having their bodies somewhat circular in shape, and from opposite sides thereot there project outwardly the arms E,which are adapted to enter the slots or notches in the legs of the shackle IE, and thus lock the latter, the body of each bolt being of small diameter,and revolving within thelock-case Without engaging with said shackle. By this construction a slight rotation of the bolts is sufficient to cause the arms E to engage with the legs of the shackle, and a thick lock-case is obviated, as said arms play in the oblong ends of the case, and the width ofthe case is only slightly greater than the diameters of the bodies of the bolts, thus reducing the weight of the lock and imparting a more graceful appearance to a lock of the class, it also being noticed that the lock-case has chambers A', which are outside of the central chamber and at the ends of the lock-case in communication with the chambers which receive the legs of the shackles,and that when the lock is open the arms E, which are narrowand projecting from the periphery of the body of the lock,abut against the walls of said chambers A', thus stopping the rota tion of the bolt, and, asis evident, limitingthe extent of rotation thereof. For a lock of increased size the case and arms are widened, but the thickness of the case is not increased, and thus thethickness of locks of various sizes may remain the same. Connected with each bolt is an annular-shaped piece, F,Which is cut away or formed with a throat, as at G, and forming a housing, witliin which is located a tumbler, I-I, the latter being of angular form or somewhat L-shaped and pivoted to the bolt,

one limb, c, being adapted to be engaged by a suitable key for unlocking purposes, and the other limb, b, occupying the throat G, so that when locking is required the bolt is operated by the key,and the limb b of the tumbler moves through the throat Gr and comes in contact with the wall J, or some other stationary part within the lock-case, thus securing the bolt and preventing unlocking action of the same-a feature of importance in alock ofthe class when employed for railroad and other purposes and subjected to shaking movements due to the motion of a train, &c. A spring, K., bears against the housing or piece F and the limb ot' the tumbler, and serves to hold the tumbler in locked position, thus insuring the locking action of the bolt.

\Vhen the padlock is to be unlocked, the key is inserted in the case A and rotated, and the tumbler is raised and the bolt and tumbler are moved from the position shown in Fig. 3 to that shown in Fig. 2. Each bolt is provided with a tumbler and covered by a key-ward plate, as shown in Fig. 6, said bolt, tumbler, and plates forming one set of works,and several of such sets may be employed for each lock,as seen in Fig. l.

Having thus described my invention, what IOC I claim as new, and desire to secure by Letters 2. A padlock of the order named, having a Patent, isshackle,a bolt, a housing secured to said bolt,

l. A padlock of the order named, having a and a spring-pressed tumbler, the latter being I5 partially-rotatable bolt consisting of a flat pivoted to the bolt and adapted to engage with 5 plate with narrow arms projecting from the the Wall of the lock-case, the parts being comperiphery thereof, said arms, when the lock is bined and operatingsubstantiall y as described. open, abutting against the walls of the end chambers of the lock-case, thus limiting the L. HILLEBRAND. rotation of the bolt and adapting the lock to Io be made of increased wid th without increasing Witnesses:

the thickness thereof, substantially as de- JOHN A. WIEDERSHEIM, scribed. A.v P. GRANT.
