IMPROVEMENT IN TRUNK-LOCKS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEONHARDT UITTING, of Philadelphia, Pennsylvania, have invented an Improvement in Trunk-Locks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and Ato the letters of reference marked thereon.

My invention consists of a spring-bolt and one or more tumblers, constructed, arranged, andA operating in the peculiar manner fully described hereafter, so that a self-fastening device and an ordinary locking-bolt operated by a keyrmay be combined in one lock, which aiords greater security than the ordinary self-fastening lficks usually attached to trunks.

In order to enable others skilled in the art to make and use my invention, `I will now proceed to describe'its construction and operation.l On reference to the accompanying drawing, which forms a part of this specication- Figure 1 is a vertical section of my improved trunk-lock; and

Figures 2, 3, and4, interior face'views of the same. l

The red lines A in g. 1 represent a portion of the front of a trunk, and B a portion of the lid. D is that part of the case of the lock which s let into the front ot' the trunk, and c the plate bearing against the same and secured to the case by rivets passing through lugs a a. E is the bolt .arranged to slide in guides on a plate, Ii, secured to the case, andfacted. on by a spring, b'. The bolt has a projection,f, which, as seen in iig. 2, occupies a position across a vertical slot, d, in front of the case, and projects through a staple, It, which passes through the said slot and is secured to or forms a part ofthe hasp-plate Gr, the latter being hinged, as usual, to

the plate II, secured to the llid B of the trunk. A tumbler, I, is hung to a pin onthe bolt E, a notch in this tumhlertting over a projection, c', on the plate F, Awhen the bolt is in the position seen in g. 2, the tumbler having a spring, j, bearing against the projection c on the said plate F. As seen in fig. 4, the bolt is in such a position that its projectionf'does not extend entirely across the slot d, lso that on applying pressure to the hasp-plate Gr its staple t passing into the slot will bear against the bevclled portion x of the projectionf of the bolt and forcethe latter back until the staple projects so far into the lock that the projectionf eanpass through it, when the holt will spring back to its original position (fig. 4) and lock the trunk. Should it be required to draw the bolt back from this position and unlock the trunk, all that is necessary is to adjust the key to the pin i m and turn it in the direction of the arrow, (fig.'4,) when. the key will raise the tumbler, and, bearingl against the projection n of the bolt, move the -latter back, and thereby permit the withdrawal of the hasp, the latch recovering its original position on releasing the key. Should itbe desirable, however, to fasten th'e hasp more securely, the key is turned in a contrary direction, thereby lifting the tumbler and moving` the bolt to theV position shown in iig. 2, so that its projectionfshall extend entirely across the slot d of the case. In unlocking the trunk, the bolt must he operated by tivo movements of the key, the first movement causing the bolt to assume the position shown indig. 4 and the second movement drawing the bolt back tothe position shown in iig. 3. A I v It will be seen thatthe above lock'possesses all the advantages of a self-latching device with the additional advantage of an ordinary lock requiring the aid of a key to operate the bolt. It will be evident to those familiar with the construction of' locks that additional tumblers may be applied, if desired. i I

I claim as myinvention, and desire to secure by Letters Patent- The spring-bolt `lil and tumbler I, or its equivalent, constructed and operating substantially asdescribed, so that a sel-fastening device and an ordinary locking-bolt, operated by a key, may be combined in onelock. In testimony whereof I have signed my ria-lne to this specification in the presence of two subscribing witnesses.
