Patented Oct. I2

UNITED A STATES PATENT OFFICE..

ALEXANDER C. FRANKEL, OF NEWARK, NEW JERSEY, ASSIGNOR TO JACOB LAGOWITZ, F SAME PLACE.

TRUNK-FASTENER.

SPECIFICATION formingpart of Letters Patent No. 233,229, dated October 12, 1880.

Application filed April 15, 1880. (Model.)

To all whom t may concern:

Be it known that I, ALEXANDER C. FRANK- EL, of Newark, in the county ot' Essex and State of New Jersey, have invented certain Improvements in Trunk-Fastenings, of which the following` is a specification.

M v invention relates to a catch or fastening applicable to trunks, chests, 85o., to hold them shut; and it consists in the peculiar constructo tion and arrangement of parts, hereinafter described in detail.

Figure 1 represents a face 'view of my device in its locked position; Fig. 2, a central section of the same on the line .fr x of Fig. l;

Fig. 3, a similar section ot' the same as it appears when unlocked; Fig. 4, a section on the line y y.

A represents the body of the device consistin g of a plate provided with holes to receive zo fastening-screws and with a front projection, a, which latter has its rea-r side made hollow to receive a spring, and notched at b b to receive the upper end ot' the catch or hasp.

B represents the hasp or catch, having at the upper end a cross-bar, c, seated in the notches b in the back of the body. From the ends ofthe cross-bar the hasp extends downward along both sides ofthe projection a, and terminates at the lower end in a tongue orend 3o provided with a lip, d., and adapted to enter and engage rml y with the keeper-plate. The lip d has an upward inclination, in order that it' may engage the more securely with the keeper and prevent the device from unlocking 3 5 accidentally.

In order that the lip maybe locked upward into the keeper, as stated, the recesses or grooves b in the body are made ot' such length as to permit a limited vertical play ot' the 4o hasp, and in the back of the body beneath the upper cross-bar of the hasp there is mounted a spiral spring, e, which serves to urge the hasp upward. When the hasp is fastened the spring holds it upward and prevents the lip d from unlocking; but when it is desired to unfasten the device a slight downward pull or pressure will overcome the spring and depress the hasp, so that it may be disengaged and turned upward, as represented in Fig. 3. The

5o pressure ot` the spring also causes sufficient friction to keep the hasp in its elevated posisition when released and turned upward, as in Fig. 3. When the baspis depressed a slight pressure is sutlicient to cause the parts to lock.

In order to insure a smooth easy action of the parts a thin metal back plate, g, may be used behind the body, as shown.

The keeper-plate C is recessed, as shown, to receive the hasp, and in order that the latter may not be broken when the trunk is rolled or 6o thrown about the keeper and the middle of the body are raised, as shown, to protect the hasp from blows.

ln order to relieve the hasp and give the trunk additional security the body ot' the fast- 65 ening is provided with two studs, h, which enter corresponding recesses in the keeper, as shown.

It will be noted that in my device the spring is not designed to and does not receive the 7o strain, but that it serves merely to hold the hasp in its locked and unlocked positions, while the spring permits a very limited longitudinal movement ot' the hasp, in order that the latter may be unlocked and strain applied to open the lock will be resisted by the full strength ot' the hasp locking tirmly and rigidly in place.

What l claim as my invention isl. The combination ot' the body-plate, the 8oA outwardly-swinging hasp connected securely to said plate, and havinga slight longitudinal play thereon, the keeper, and the spring arranged to urge the hasp upward, as described and shown.

2. 1n a trunk-tastener, the combination of the body-plate, the outwardly-swinging and longitudinally-lnoving hasp, and the spiral spring arranged to urge the hasp upward endwise, and also to hold it in an elevated posi- 9o tion when unlocked.

The combination of the body-plate, the spiral spring, the outwardly7 swinging and longitudinally-moving hasp arranged to engage solidly with the body-plate and provided with the upwardly-inclined lip, and the keeper recessed to receive said lip.
