LOCK MECHANISM.

To all whom it may concern: 7

Be it known that I, HARRY SEDER, a citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Look Mechanism, of which the following is a specification.

My invention consists in a new and imprpved lock mechanism for trunks, suit cases, and other containers, and the purpose in view isthe provision of increased security of combining in a novel form of lock the functions of both a key lock and a pad lock.

Generally speaking my improved locking mechanism is of the following construction. One portion of the container, usually the lid, is provided with a pivotally mounted hasp, while the body or other part of the container is provided with a modified spring lock mechanism. The spring actuated bolt plate of the lock is provided with a projecting keeper which extends through the slot in the hasp and is provided with a notch which engages the hasp and prevents its being swung away from the keeper, unless said keeper is forced aside against the action of the lock spring. When the hasp is swung down over the keeper it automatically engages said notch. By turning the key in the proper direction, the keeper is locked stationary and cannot release the hasp until the key is inserted and turned into its unlocked position.

Many novel features of construction and arrangement of parts will appear from the following description.

In the accompanying drawings, Figure 1 is a face View showing my locking mechanism in use and double locked, the pad lock being shown in dotted lines; Fig. 2 is a similar view with the pad lock omitted and the hasp and cover plate of the key lock in dotted lines, to better show the lock mecha nism; Fig. 3 is a longitudinal section through the hasp and lock, and Fig. A is a similar view with the hasp and the sliding key hole member omitted for the sake of clearness.

The following is a detailed description of the drawings.

A is the hasp which is hinged to a plate B which may be riveted, as at 1 to the lid of a trunk or other container with a hasp A depending. The hasp is provided with a longitudinal slot 2.

Specification of Letters Patent. ,l atented June 10 1919. Application filed April 1, 1919. Serial No. 286,652.

C is the back plate of the lock riveted, as at 3, to the under side of the cover plate D; while said cover plate is riveted or secured, as at 4, to the body of the trunk, or other container. The central portion of the cover plate D is pressed out to form a compartment with the back plate O within which is assembled the key lock mechanism.

Said key lock mechanism is shown as of the following construction. E is a sliding bolt plate having'its upper end provided with an outwardly projecting keeper F which protrudes through a slot 5 in the cover plate D and is provided with a hole '6 for the attachment of a padlock G. 5 are guide shoulders on the back plate C to keep the bolt plate E in proper alinement. The cover plate D is provided with a sunken panel 7, extending from its top edge and surrounding the slot 5, into which depression the hasp A fits when swung down into place over the keeper F. The lower edge of said keeper is provided near its base with a notch 8 which the hasp A engages, the end of the slot 2 of the hasp being undercut or shouldered, as at 8 to fit into said notch, thus forming a snug interlocking engagement be tween the hasp and the keeper which is concealed and cannot be forced by a knife blade or other tool.

The bolt plate E is resiliently held depressed, with the hasp A engaged by the notch 8 of the keepeigby means of a folded leaf spring 9 interposed between the studs 10 on the bolt plate E and an internal shoulder 11 on the cover plate D formed by the lower end of the panel 7 The outer end of the keeper F is rounded, so that, when the hasp A is swung down over the keeper, the latter is forced upwardly, compressing the spring 9 until the hasp seats in panel 7 when the keeper springs downwardly with the notch 8 engaging and holding stationary the hasp. Thus the lid is held shut until the bolt plate E is forced upwardly against the spring 9.

The lower portion of the cover plate D is provided with a slot 12 through which protrudes the key spindle 13 of the bolt plate E, and H is a key hole plate held against the face of the cover plate D by means of integral tongues let which extend down through the slot 12 and are fixed in the bolt plate E. Thus the plate H slides in unison with the bolt plate E and said bolt plate may be elevated against the action of the sprin 9, to release the keeper F from the hasp A,I)y pushing the key hole plate H upwardly with the thumb. ,The key hole plate H registers with the key spindle 13 so that avkey may be inserted to throw the spring mounted slide I toward the left in Fig. 2 so as to engage the wider side of the projection 15 of the base plate C, thus looking the bolt plate and its keeper against upward movement and thereby preventing the disengagement of the hasp from the keeper. A reverse movement of the key will return the slide I back to the position shown in Fig. 2, thereby unlocking the key look so that the bolt plate keeper may be elevated, against the action of the spring 9 to release the hasp.

My improved duplex lockpresents a number of substantial advantages over the prior art. The hasp and keeper which are used in connection with the padlock are parts of the key lock mechanism, and therefore I avoid any material inerease of manufacturing cost, and I also am enabled to confine the looking operation to the center or other selected point on the lid and body of the container. By using the padlock keeper as the locking portion of my spring bolt plate, I obtain a more compact and 'sightly structure, and in case the lock key is'lost, I may use the pad lock for locking the container and the bolt plate for the spring catch used for temporarily holding the container closed without looking. I

, The most usual application of my invention is for the purpose oif loeking traveling or shipping containers, either giving double locking security 013w enable one form of locking action to be'used when the other form is out of commission, such, for instance,

as through the loss of either the key lock key i or the pad lock key or the pad lock itsel However, my invention may be applied with great advantage to boxes for storing securities or other valuable where the box is to be opened only with the consentand in the presence of two persons. Thus both locking actions can be used, the key lock key being retained by one person while the pad lock key is retained by the other.

What I desire to claim is z 1. In a duplex lock of the character described, the combination of a spring actu ated sliding keeper, provided with a notch,

for attaching a pad lock to said keeper out- 7 side of said hasp.

3. In a duplex lock of the character described, the combination of a spring actuated bolt plate, a notched keeper carried thereby, a slotted hinged haspl adaptedto be swung down'over said keeper and tofengage said notch, means for locking said bolt plate stationary, and means for attaching a pad lock to said keeper outside of said hasp.
