HASVP-LOCK.

SPECIFICATION forming part of Letters Patent No. "771,814, dated October 11, 1904.

Application led December 31, 1902. Serial No. 137,301. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH DAvY, acitizen of the `Republic ofv France, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Hasp-Locks, of which the following is a specification.

My invention relates to locks, and more particularly to that classl of such devices in which a hasp-fastener and a lock are combined in the same structure.

In the patent granted to me January 9, 1900, No. 640,637, I provided the lock portion with two reciprocating spring-pressed pins or plungers, one of which was adapted to be operated by the key and to in turn operate the other plunger and withdraw the locking pin or bolt which formed a part thereof; but I have discovered that by the use of a different form of key I can dispense with one of the plungers and operate the other plunger and lock with the key direct, thereby simplifying the construction and making a safer and more desirable lock.

The accompanying drawings illustrate the present invention and form a part hereof, the same reference character indicating the same part in each of the views in which it occurs.

Figure 1 is a plan view of a lock embodying my invention,the hasp being shown closed and locked in full lines and unlocked in dotted lines. Fig. 2 is a similar View, the hasp being broken away and the top of the lock removed. Fig. 3 is a view in longitudinal side elevation of the construction represented by Fig. 1. Fig. 4 is a sectional view showing the position which the parts of the lock occupy when the key is inserted. Fig. 5 is a similar view showing the key after it has been turned preparatory to withdrawing the bolt. Fig. 6 is a similar view with the key forced in and the bolt withdrawn. Figs. 7 and 8 are respectively a side elevation and an end view of the bolt receptacle or casing. Figs. 9 and 10 are similar views of the bolt. Fig. 11 is a partly-broken side view of the key.

Referring more particularly to the drawings, 1 indicates the shell or case of the lock, which shell or case is secured to a plate 2 in any suitable manner, preferably by means of long in cross-section and extends from the bottom of the shell I above its said cavity 4 to the plate 2 and is clamped therebetween when the plate is riveted to the shell. A thin flat projection or leg 8A extends from the lower end of the casing 7 and fits in the recess or cavity 4 to assist in holding said casing from turning when the lock is being operated. The casing 7 is further provided with a longitudinal bore 9, within which is placed a longitudinally-mov able bolt 10. The side of the casing 7 adjacent to the guide-pin 5 is slotted longitudinally, as at 11, into the bore 9 and notched along one edge to form stops or wards I2, the bottom of the notches being preferably inclined, as shown at 13. The bolt comprises a pinlike locking portion, (marked 10,) a cylindrical central portion 14, which iits the bore 9 of the casing 7 and from which the part 10 projects, and a guide-strip 15. The pin 10 is of a less diameter than the central portion 14, and thereby forms a shoulder 16, which engages with the plate 2 when the bolt is projected outward into its locking or operative position. The guide-strip 15 extends from the shoulder 16 along one side of the central portion 14 and projects below the end thereof and terminates in a step 17. lt iits within the slot 11 of the bolt-casing and prevents the bolt from rotating on its axis While being operated and holds the step 17 at the bottom in a line with the bits 18 of the key 6 after they have passed the wards 1Q and the key is in position to be forced inward to withdraw the bolt, the step being at such a distance of the end ward as to permit the entrance of the bit of the key.

A spring 19 is placed in the bore 9 below the bottom of the central portion of the bolt IOO lcavity Ll.

'movement of the key can only occur when the key has been rotated sufficiently to permit a iin or projection 2O on its stem to enter the slot or elongated portion of the keyhole 21, formed for the passage of the bits 18. The lin 20 is preferably formed diametrically opposite these wards, so that the key must be given a half-turn before it can be pushed in to withdraw the bolt.

The plate 2 is adapted to be secured in position by means of screws in the ordinary manner and has upon its exterior a substantially U-shaped staple4 or staple-like projection 22, provided with annular ends 23. One leg of this staple is formed upon or secured to the plate 2 and the other one is directly above the first leg and at such a distance therefrom as to admit of a locking-bar 24 being mounted so as to swing between them. The bar 24 pivots upon and around a hollow bolt 25, within which is formed the keyhole 21, and which bolt passes also through the annular ends 23 of the staple. As shown, the hollow bolt has a flange 26 at its outer end, which is seated on the ringof the upper leg of the staple, and at its inner end it is rigidly secured to the plate 2. The lower leg of the staple is provided with a perforation 27, which extends through the plate 2 and through which perforation the pin portion 10 of the locking'- bolt projects to prevent the bar 24 being swung into its releasing' position, which is all that is necessary when the box or other receptacle to which the lock is applied is empty; but when it is desired to more securely fasten the lock the end l() is caused to enter either one of two holes 2S, which are formed in an expanded portion 29 of the bar, the same being adapted to be swung' between the legs of the staple until either hole 28 registers with the hole 27 in the lower leg'.

rl`he lower leg of the staple 22 is of substantially the same thickness as the hasp, (herein marked 30,) which it is designed to receive, so that when the hasp is turned down with its slot 31 fitting over the U-shaped staple the locking-bar 24 can be swung cross- Wise of the legs of the staple and will thereby prevent the removal of the hasp. The bar 24 is pivotally mounted somewhat olf its center, and therefore has one end longer than the other, which keeps it from passing' between the legs of the staple at the closed end. Itis understood that' the hasp 30 is flexibly secured at one end to one portion, as 32, of the receptacle to which it is applied, while the lock is secured to another part, as 38.

In operating my improved lock when it is only desired to give it what may be called partial security the locking-bar is turned into alinement with the legs of the staple on the lock, and the hasp is thrown down over the same. The bar is then turned laterally to one side or the other, which Will cause the end between the legs to be moved from over the bolt and release the same, so that the spring can force it outward. It will now be impossible to return the bar to the required position for releasing the haspuntil after the bolt has been forced in, and thus is obtained ordinary security; but when it is desired to more securely fasten the bar against being returned to its opening position the perforated end is swung around until the bolt can enter one of the perforations, in which position it will be impossible to withdraw the bolt by any means except by inserting' the key into the.

keyhole. After the key has beeny inserted and has engaged the shoulder formedby the juncture of the shell 1 and thecavity 4p it is given a partial rotation untilitsfin willenter the bit-slot of the keyhole and then it iS, forced inward, which causes one of. the bits of the key, preferably the end one, toengage with the step on the inner end of the bolt and force the bolt inward against the tension ofl its spring. In this position the bar can be turned to lock or unlock the hasp, after which the key can be removed from the lock byreleasing' it and letting the spring forceit out until the lin is abovethecasing, when a partial rotation Will bring the bits into register with the bit-slot and permit the removal of` the key. This lock, it will beobserved, is

capable of the same generaly application asy that of my previous patent aforementioned. Thus, for example, it is well adapted for use on boxes and chests of every description,

packing and shipping cases, gates, freight-car.

doors, &c.

I have shown and described hereink what I consider the simplest and cheapest form` of my improved lock; butitis evident that many changes can be made in the same Without departing from the fundamental principle of; my invention. For instance, the number., ar. rangement, and relative directionof thebits of the key and coacting partsofthe lock can,

be varied indelinitelyfand the lock may be made much more complicated, if deemed desirable. I therefore reserve the. right to make all such alterations or modifications as come Within the scope of` my invention.
