LOCK.

Application filed May 9,1921. Serial m'.-467, 71.

To all whom it may concern:

Be it known that I, JOHN Rousseau, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented new and useful Improvements in Locks, of which the following is a specification.

This invention relates to looks, and more particularly to a lock designed for use in tageous features of the present system of locking cars withseals and in addition will protect the contents of the car from theft and also to provide a standard locking mechanism operable by a universal key, one of which will be retained by persons who are entrusted with the duty of opening and closing the loaded cars. At the present time it is the duty of the man in charge of such work to record the numbers of the seals applied on each car and it is a further object of the invention to provide a lock mechanism which includes in combination with a locking shackle and recorder .mechanism which is operable upon each unlocking movement of the shackle to change one digit of the number of the recorder thereby permitting the recording of the proper number of the lock on each car as loaded, which number may also be recorded at the various terminals en route the car in a like manner to the system in use at the present time.

Other objects of the invention will appear in the following detailed description and in the accompanying drawing wherein:

Fig. 1 is a side elevation of the improved lock showing it in an unlocked position.

Fig. 2 is a section of the lock showing it in locked position.

Fig. 3 is a cross section taken on the line 3-8 of Fig. 2.

Fig. 4 is a section through the improved lock showing it in locked position.

Fig. 5 is a vertical section through the lock taken on-the line 5-5 of Fig. 4.

Fig. 6 is a horizontal section through the lock on line 66 of Fig. 4.

Fig. 7 is a fragmentary perspective of a modified form of the shackle.

Referring more particularly to the drawing the improved lock comprises a body 1 having spaced side channels '2 and 3 for receiving the shanks 4 and 5 of the shackle 6 of the lock. The shackle 6 is substantially in the shape of an inverted U and is provided with a locking lug 7 extending parallel to the shanks 4 and 5 intermediate them and inwardly from the bight portion 8 of the shackle. The locking lug or bar 7 is positioned intermediate the shanks 4 and 5 and engages in a recess 10, formed in the body 1, when locked for holding the lock in a rigid position on a car so as to make it practically impossible, when the lock is locked, to move the same in any direction. If it is so desired, a chain may be attached to the housing 1 and securely attached to the car for preventing loss of the look, without departing from the spirit of this invention. The shanks 4 and 5 of the shackle 6 are provided with recesses 11 and 12 in theirprovided with a key receiving recess 19 of particular shape in cross section so that it which engage the rack teeth 18 on the locking bolts 13 and 14. The cylinder or barrel 15 is.

can only be rotated by the insertion thereinto of the proper key. If desired, the lower ends of the shanks 4 and 5 may be beveled as shown at to provide cam surfaces for riding over the upper inclined surfaces of the ends of the locking bolts to permit look:

ing of the shackle in place.

Positioned within the body 1, above the locking bolts 13 and 14, is a recorder structure 21 of any conventional type embodying a plurality of cylinders successively rotated for recording numbers and the ratchet teeth 22 formed upon the unit cylinder 23 of the recorder structure are operated upon outward or unlocking movement of the shackle 6 by a spring pressed pawl 24 pivotally carried by the shank 5 of the shackle and normally urged into ratchet tooth engaging positlon by a spring 25 which spring is adapted to be tensioned upon the inward locking movement of the shackle to permit idle movement of the pawl 24 over the ratchet teeth 22.

The body 1 is provided with collar 26 surrounding the entrance openings of the passageways or chambers 2 and 3 and the outer surfaces ofthese collars or bosses are beveled, inclining downwardly and outwardly away from the opening. Corresponding collars 27 are formed upon the shanks land 5 for snug abutting engagement with the bosses 26 to provide substantially fluid tight closures for the entrance openin s into the chambers 2 and 3 and prevent moisture from. entering the lock struc ture and interfere with its efiiciency.

In operation, each time the lock structure is unlocked the recorder will be operated, changing the number exhibited through the window opening 30, in the body 1, one digit and thus any unauthorized or malicious opening of the car on which the lock is applied may be easily determined by comparing the number shown through the window opening 30. it is desirable to provide a number, preferably live, of the digit cylinders in the recorder which will make it diiiicult to run the numbers back to the one originally exhibited, for instance, if the number exhibited through the window 30 was 999, it would be necessary to unlockthe lock 99,999 times to bring the number 999 back to view through the window. The provision of the pluarality ot' the cylinders in the recorder mechanism will permit the use of the lock for an indefinite period.

Owing to the fact that some of the look ing staple on freight cars are shorter than others it may be necessary to provide a forked lower end for the locking lug 7 and in Fig. 7 of the drawing, such a structure is illustrated wherein the lower free end of the shank 7 is forked providing arms 7 and 7 which are adapted to engage upon opposite sides of a staple.

If it is so desired protector 40 and 41 ma be provided for protecting the locking cylinder 16 and window opening 30, which protectors are pivoted as shown at 42 to the housing or casing l of the lock and have spiral springs 43'associated therewith to normally hold them, in closed position.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth inthe claims hereunto appended,

Having thus described my invention what I claim is: i

1. In a lock, a body, a substantially U- shaped shackle having spaced shanks, said body provided with entrance openings to receive said shanks, said shanks having recesses upon their inner faces, a rotatable cylinder extending transversely of the body, teeth on said cylinder, a locking bolt upon opposite sides of the cylinder engaging said teeth, springs normally urging the outer 7 ends of said locking bolts into the entrance openings for engaging the recesses in the shanks to retain the shackle in locking position, a recorder mechanism carried by said body, and means operable upon unlocking movement of said shackle to operate'said recording mechanism. 7 r

2. In a look, a body, a substantially U- shaped shackle having spaced shanks, said body provided with entrance openings to receive said shanks, meanscarried by said body for locking said shackle in locked po sition, a recorder mechanism carried by said body including a rotatable unit cylinder, ratchet teeth on oneend of the unit cylinder, one of said shackles having a recess, a pawl adapted to be disposed within the confines of the recess when the shank is inserted in its respective entrance opening, a spring for urging the pawl into engagement with the ratchet teeth on the unit cylinder for rotating the cylinder uponunlocking movement of the shackle.

In testimony whereof I atfix my signature.

JOHN ROUSS EAU.
