SPECIFICATION forming part of Letters Patent No. 399,083, dated March 5, 1889.

Application filed December 14:, 1888. erial No. 293,602. (No model) f0 MU 1117mm 7 23 721461] concern lie it known that 1, JAMES ROCHE, of Terryville, in the county of Litchfield and State of (onnecticuthave invented a new Improvement in Locks; and I do hereby declare the i following, when taken in connection with acas applied to a trunk; Fig. 2, a vertical central section of the same; Fig. 35, a view of the 1 case of the lock, the face-plate removed, showing the bolt in the unlocked position; Fig. 4, the same as Fig. 3, but the bolt thrown to the locked position; Fig. 5, a horizontal section through the case, showing a top view of the bolt: Fig. 6, the invention as applied to a chestlock: Fig. 7, modification.

This invention relates to an inuirovcment in lhatclass of locks in which a loop-like staple is emploved in connection with the lock, the staple being adapted to enter the lock-case and the bolt of thelock to engage therewith such as used in trunk-locks, when the staple is a part oi a hasp and arranged to enter through an opening in one edge of the case, i

and partimilarly to those latches of this eharrocking movement of the bolt throws it from actor in which the bolt swings as upon a pivot in the case, having a spring arranged which is adapted to throw the bolt to either its locked or unlocked position a flier the key shall have turned the bolt 'to one side of the center of its movement, the spring operating to complete the movement in both directimis.

In the usual construction of this class oi. locks the kev has been required to throw the bolt both to the locked and unlocked position.

The object of my invention is to adapt the lock to be sell-locking, so that when the staple is forced to place it will throw the bolt into the locked position without the presence of the key; and it consists in constructing the rocking holt described with an inclined surface against which the staple or a projection moving with the staple is adapted to strike as it enters the case, the staple or its projection acting on the said inclined surface as a cam, giving to the bolt a sufficient movement to carry itover the cent r toward the locked position, when the spring comes into action to complete the locking movement.

I will-first describe the invention as applied to a trunk-lock, in which A is the front or face plate, and B the hasp hinged in the usual manner, the hasp being provided with a staple, which is adapted to enter an opening, I), in the face of the lock in the usual manner for this class of locks.

E represei'its the rocking holt. It is supported upon a pivot in the lower part of the case, (here represented as a stud, F, standing in an opening, (1, in the lower part of the case 11,) the case being of the usual box-like charactor and secured to the front in the usual manner.

The bolt is constructed with an opening, I, through it into which the key may enter through thekey-hole J in the face of the lock, K representing the spiudle-bcaring' in the case for the ke v-s ;)indle. In the illustration this hearing is a hole in the hack of the case, into which the end L ol the lip of the key (see Fig. 2) enters, so as to support the inner end of the key; but for this opening there may be substituted the usual stem. The belt is constructed with a nose, All, on one side, which is adapted to engage the staple. The

the unlocked position, Fig. 33, to the locked position, as seen in lrig. at; the nose M of the bolt engaging the staple in the locked position, as seen in Fig. 4; but when thrown to the unlocked position, as seen in Fig. 3, then the staple is free.

X represents a spring, preferably a flat steel spring, one end seated in a stationary point, as at O, in the case, the other end hearing upon a seat, as l, on the bolt. The springseat 1 on the bolt is in such relation to the spring-seat O in the case that in the rocking movement of the bolt the seat l passes across the central line of action of the spring that is, a line drawn from the stationary springseat 0 to the pivot on which the bolt turns, (the said line indicated in Figs 33 and eh) so that, the bolt being in the unlocked position, as seen in Fig. 3, the spring-seat is on the bolt side of the said line. Now if it be applied to throw the bolt the spring will be compressed in the movement of the bolt until the seat P has passed the said line. Then the spring comes into action to throw the bolt to its ex tremc position, as seen in Fig. 4, independent of the key, and the spring there holds the bolt until the key has returned to move the bolt and until the seat P shall have again passedthe said line. Then the spring will operate as before and throw the bolt to the extreme open position. To permit the flat spring to thus throw the bolt, it is made of serpentine shape, whereby it is adapted to expand or be contracted longitudinally. Thus far the lock is of common construction, and for its operation it is necessary to employ the key both to throw the bolt to the locked or the unlocked position.

To make the operation of the bolt automatic or independent of-thc key, 1 construct it with a cam-like projection, R, forward of the nose of the bolt, but inclined toward the nose end of. the bolt, as seen in Fig. This cam projection R, when the bolt is in the unlocked position, as seen in Fig. 3, stands in the path of the entering staple, and so that the staple being pressed operates upon. the said cam projection R, and causes the bolt to turn toward the locked position until the sprin -seat shall have passed the said line.

' Then the reaction ofthe spring will continue the movement of the bolt until the nose has entered the staple and reached the fullylocked position. In the locking operation, therefore, it is only necessary to press the staple home, and the bolt automatically flies into its locked position, from which it may be unlocked with the key.

In the case of a chest-lock, in which the staple enters from the top, as seen in Fig. 6, the cam projection R is inclined accordingly, so that as the staple enters it will operate upon the said projection and throw the bolt as before described, it being understood that the incline of the cam projection R is oblique to the plane of the staple of the lock, and this irrespective of whether the staple enters through the face or through the edge of the look.

I prefer to make the pivot of the look as I have described, by constructing the bolt with a stud-like projection upon its lower end; but the construction of the pivot is immaterial, as it may be of any suitable constructionsay as a stationary pivot in the ease through the bolt, as seen in Fig. 6.

I prefer to arrange the cam projection on the bolt so that it will be operated directly by the entering staple; but it may be arranged so as to be operated indirectly by the entering staple, as seen in Fig. 7, where the cam projection is shown as formed in the rear of the nose of the bolt instead of in front of the nose. In this case a projection, S, is provided, which moves with the staple, and so as to enter the casein like manner as the staple, and in so entering will strike the cam projection, as seen in Fig. 7, and force the bolt toward the locked position, as indicated in broken lines; but in any case the operation is produced substantially by the entering staple. I do not therefore wish to be understood as limiting the invention to the direct action of the staple; but by the term staple, as used in the claim, I wish to be understood as including either the direct or indirect movement of the staple, as I have described.

I claim In a lock in which a staple is adapted to enter the case to be engaged With the bolt, the bolt hung upon a pivot within the case, and adapted to rock on said pivot in the plane of the case, the bolt constructed with a nose arranged to engage or disengage the staple entering the case, a spring arranged between a stationary bearing in the case and a corresponding seat on the bolt, the said seat on the bolt being adapted to cross the central line of action of the spring as the bolt moves from one extreme to the other, the said bolt constructed with a cam projection in the pat-h of the staple as it enters the case when the bolt is in the unlocked position, the said cam projection inclined to the path of the staple as it enters the case, substantially as described.

JAMES ROCHE.
