CONRAD LIEBRICH,` OF PIIILADELPHIA, PENNSYLVANIA.

TRUNK-Look Hasi.

Specification forming part `of Letters Patent No.` 10,862, dated May 2, 1854; Reissued April 15,

To all whom it may concern Be it known that I, CONRAD LIEBRICH, of

the city and county of Philadelphia and.

State of Pennsylvania, have invented certain new and'useful Improvements in the Construction of Hasps for Trunk and other Locks; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompany-` ing drawings, making a part thereof, in

. whichdropped shut, the` catch of the hasp would strike against the trunk frame, and frequently break them o, and always cut or damage the trunk. A still greater difficulty with the uncontrolled 1hinge when applied to self locking locks, is that when the lid of the trunk drops it is frequently locked by the jar of such accidental dropping. Another serious objection to the present form of hasps, is that, the strain or tendency of the lid to open comes entirely upon the catch, which being slight and riveted to the hasp is not capable of sustaining any very great force.

The object of my invention is to remedy both these serious objections, and may be said to consist first; in the application of a spring attached to one part of the hinge and pressing or so acting against the other part, as that the hinged portion of the hasp will always stand in such inclined position, as to avoid striking the trunk frame in lett-ing down the lid, and to prevent the hasp catch from entering the lock, until pressed in against the action of the spring. Second, in setting the hasp catch in a solid projection cast with the hasp, which solid projection enters the lock sufliciently far to receive the Strain or `tendency of the lid to open, thus takin the force from the catch itself, and

transferring it to the solid metal, which makes the hasp more substantial and less liable to be forced open.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

The hasp is cast or wrought in two pieces A, B, and for the purpose of lightness may be cast partially hollow on the under side as seen by the double lines in Fig. 2. On the upper part A, of the hasp is attached a spring a, the point of which presses against the lower part B, so that said lower part will always, unless the hasp is locked, stand as represented in Fig. 4. On said upper part A, are cast two recesses b, b, into which two journals or axes c, c, cast or wrought on the lower part B, rest and turn, being held therein by the spring a. This without any farther fastening forms the hinge; and as i the spring is on the under side of the hasp, and the pivot of the hinge solid or fast to the lower part of the hasp, the hinge or joint or catch stick in the lock, there may bev something to catch hold of to draw it out. A Another important feature in this spring hasp is that, under ordinary circumstances,

when used with spring or self locking locks,

it is only necessary to turn the key and the hasp catch flies out of the lock itself. To those who have attempted to hold the lock bolts back with key in one hand to draw and hold out the hasp catch with the other, and then raise the lid of the trunk, the convenience of the spring hasp will be very obvious. j

In Fig. 4, d, represents the projection which is cast solid with the part B of the hasp the catch e, being riveted in it as seen in the drawing. This projection (Z, enters the lock or the escutcheon far enough to catch against. the lock plate and take the strain vincident to the rising of the trunk lid into the solid metal, and relieving the catch e from a force which'it is not well calculated to withstand,

g I p 10,862

Having thus fully described the nature of projection which enters the lock With the 10 my invention what I claim therein as neviT hasp catch, and takes all the strain incident and desire to secure by Letters Patent is upon the tendency of the lid to open, and

1. The so combining of a spring with a thus protect the catch itself substantially as 5 hinged hasp as that the lower or hinged described.

portion thereof shall stand oil from the C. LIEBRICH. trunk, substantially in the manner and for Witnesses: the purpose described. A. B. STOUGHTON,

2. The placing of the hasp catch in a solid THos. H. UPPERMAN.
