AUTOMATIC HASP-LOCK.

To all whom 'it may concern.'

Be it known that LJOHN R. FRANCIS, a citizen of the United States, residing at Rochester, in the county `of Monroe and State of New York, have invented new and useful Improvements in Automatic Hasp- Locks, of which the following is a specification.

This invention relates to'locks and especially to locks ofthe hinged or hasp type.

The primary object of the invention is to provide a hasp which may be brought into engagement with a staple and automatically locked in such engagement until released by a key, the purpose being to provide a lock of this description for attachment to freight cars and the like in order to dispense with the usual padlock, which is liable to become lost or misplaced.

A further object of the invention is to provide an automatically operative locking bolt carried by the hasp for engagement with a staple and means for locking said bolt in its engaged position and to provide means whereby a key may be engaged with the bolts and turned to release the bolt locking means, said key also providing means for manually moving the bolt to release the same from its engagement with a staple.

With these and other objects in view the invention consists of the following novel combination and arrangement of parts, hereinafter more fully described and illustrated in the accompanying drawings, in which- Figure 1 is a horizontal sectional view through a portion of the body of afreight car, illustrating a fragmentary part of the door and the adjacent side wall and illustrating the improved hasp lock in plan view;

Fig. 2 is a front elevation of the subject matter of Fig. 1;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a vertical sectional view on the line 4-4 of Fig. l;

Fig. 5 is a cross-sectional view on the line 5-5 of Fig. 1;

Fig. 6 is a detailed perspective view of the locking bolt;

Fig. 7 is a similar view of the key.

Referring to the drawings in detail, the reference character A indicates a portion of the body of the car and B the door, to which the improved lock is secured.

As shown in the accompanying drawings,

are hidden or protected and when the hasp is located it is impossible to reach these screws to remove them. This hasp is provided with a casing 13, `which is preferably rectangular in cross-section and has formed in its rear wall an opening 14, within which is adapted to enter a staple 15 secured to the car body adjacent the door opening.

. For the purpose of automatically locking the staple 15 into engagement with the hasp 12, the casing 13 has mounted for sliding movement therein a locking bolt 16, which bolt is positioned across the opening 14 in the path of entrance of thestaple 15.

As illustrated in Fig. 6, the locking bolt 1,6 is formed with a reduced portion 17, intermediate its ends, which provides at one end an enlargement 18 in the form of a hollow rectangular frame 19. The enlargement 18 is of the proper size to provide a working fit within the casing13 and is formed within the rectangular opening provided by the frame 19 with the engaging lug 20, which is formed upon its face next the opening 14, with a cam surface 21, which is adapted to be brought into engagement with the staple 15 when the hasp is swung in the proper direction and to ride along the outer projecting portion of the said staple to move thebolt to one side to permit its entrance therein. l

To provide an additional uiding means for the bolt and to limit the orward movement 0f the same, the end opposite the enlarged portion 18 is provided with oppositely extending lateral flanges 22, which are adapted to engage the outer end wall of the casing 13 to limit the movement of the bolt in that direction. The boltvis urged into a position at this end of the casing through the action of an expansible spring 23, which has one end secured to the enlarged portion 18 of the bolt and its opposite end secured to the inner end wall 24 of the casing.

The position of the bolt 16 within the casing is such as to bring the engaging lock 20 across the opening 14, with the cam surface facing the said opening, so Vthat the staple trance through the slot.

staple and its engagement With the luO' 20 Which is again positioned across the opening 14e through the act-ion ofthe springQB'.l F or the purpose of holding the bolt againstl further movement and permitting the release ot the staple, the casing 13 has secured therein a resilient locking plate 25, Whose free end 2G is located in the path of movement of the bolt 1G and is adapted to spring into engagement With the locking notch 2T formed in this bolt.

The bolt 16 is further provided With a key receiving opening 28, which opening is provided with a lateral extension 29 located in juxtaposition With the notch 27, so that a key 30 may be inserted through the key slot 31 of the casing and engage With the opening 28. A partial rotation of the key Within this opening will cause the bit 32 to engage they plate 25 and lift it from the notch 27, when the bolt 16 may be manually moved to disengage the lug 2O from the staple 15.

In order to permit of the manual move'- ment of the bolt 16 the slot 31 of the casing is elongated, so that the key is inserted in one end'of the slot and turned to release the locking bolt, the length of the slot permitting of the longitudinal movement of the key to manually operate the locking bolt. A pivoted cover 33 is secured to the casing 13 so as to exclude dust and dirt from en- The key 30 may be of various shapes and designs, the one illustrated being provided Y With a convenient operating handle 3l, and having a shank carrying the key bit 3,2 previously mentioned.

Copies of this patent may be obtaine for five cents each, by addressing the Commissioner of Patents,

It is thought that from the foregoing description and the accompanying drawings, persons skilled in the art will be able to understand the construction, operation and various advantages of the invention. The right is reserved to make such changes in the form and proportion .thereof as will properly fall within the scope of the appended claim. For example, the Width of the rectangular opening Within the frame 19 of the locking bolt may be increased and two engaging lugs provided instead of one.

Having described the invention, what is claimed is:

A hasp lock comprising an elongate-d casing provided With an opening, a spring actuated locking bolt slidable longitudinal Within said casing and having an open top key receiving socket therein, a stationary member, means carried by the bolt for engagement with the stationary member, ar

spring locking plate located in said casing in the path of movement of said bolt and above the open top key receiving socket, Aan engaging shoulder formed on said bolt adjacent the open top of the key receiving socket for engagement with the spring locking plate to hold the bolt in locked position, a key adapted for insertion in said key receiving socket and rotatable therein to en gage the locking plate and release the latter from engagement With the bolt, said key beingl also movable longitudinally oi' the casing with the bolt to slide the latter from engagement with the stationary member.
