SPECIFICATION forming part of Letters Patent No. 292,407', dated January 22, 1884.

Beit known that I, SAMUEL G. CABELL, of Vashington, in the District of. Columbia, have invented lcertain Improvements in Seal-Padlocks, of which the following is a specification.

My invention consists in constructing the body or case of a lock with a hasp at its upper end, and vwith a flange or lip at the lower end, extending downward around and beyond the seal-holding devices to afford protection thereto, and to prevent the entrance of rain, dust&c.; also, in the peculiar combination of devices for fastening the seal-holder; also, in the peculiar arrangement of dogs to hold the main bolt of the lock; also, in an alarm combined with the lock in the manner hereinafter described. 'f

In the accompanying drawings I have shown my lock in Inodied forms, all of which,

however, embrace substantially the same features of invention.

Figure l is a side View of my lock provided with pivoted vibrating tumblers, a portionv of the casing being broken away to expose the interior. Fig. 2 is a vertical section through the lock as constructed with a revolving barrel having sliding pins or tumblers, in place of the vibrating tumblers illustrated in the preceding figure. Fig. 3 isa vertical transverse section on the line a: w, Fig. 2. Fig. 4 is a vertical transverse section on the line y y, Fig. 2. Fig. 5 is a horizontal section on the line z 0g/Fig. 2. Fig. 6 is a bottom plan view of the main locking-bolt. Figs. 7, 8, and 9 are vertical sections of different arrangements for locking the bolt. Fig. 10 is a View showing the `manner in which the free end of the haspv closes upon and around the 'case Aof the lock. Fig. ll is a cross-section of the rotary barrel employed in the plan shown in Fig. 1. Figs. 12 and 13 rare sectional viewsl illustrating theconstruction and arrangement of the alarm mechanism.-

I construct my lock, 'asy shown, of a flat rectangular form, with the hasp at its upper end, and with the key-hole'andseal-retaining devices withinV arecess in the lower end. 'The case or body consists of an outside shell, A, to

which the bail or hasp is attached at the up- 5o per end, and of an inside body or block, B, to which all the working parts are attached. The shell A is cast complete in one piece, with its upper end closed, but with its entire lower end open, and with bands or enlargements e 5 5 .around its ends, for the purpose of giving additional strength and affording additional security to those parts most liable to injury. The hasp or bail C is pivoted between studs f, formed upon the upper end of the body, the 6o latter being left complete, or without openings therein, in order to prevent the entrance of water, dust, and other foreign bodies. At its free end the hasp has the usual neck entering the opening in the body to engage with the locking-bolt E. Q that portion of the body immediately around As shown in the drawings,

the hasp-opening is raised or elevated, and the end of the hasp made of suitable form to fit Y over and upon the same,`as clearly indicated 7c in Figs. l, 2, and 10. This construction forms what I denominate a water-shed, and serves to preventwater from nding its way Vinto the l,

working mechanism when the lock is suspended by the hasp in its ordinary pendent posi- 7 5 tion. The construction oi' the lock-body and the twoparts A and B is not claimed herein,

' as it will be made the subject of a separate application.Y

Referring to the-various figures, it will be 8o seen that 'the hasp is locked in its closed position by means of a horizontal sliding bolt, E, located in the upperend of the case, and thrown forward,when released, by means of a flat spring, H, acting against its rear end. Inl 8 5 order to secure the locking of the bolt when the hasp is closed, I provide a vertical sliding bolt'or dog, G, .bearing at its lower end upon a spiral spring in such :manner that when the bolt E is retracted by means of the key the 9o dog AG is thrown upward past its forward end, in the position represented in Fig. 2, thereby holding the bolt back. When the hasp is closed, its end or nose depresses thel dog G, whereupon the bolt is thrown forward by the 9 5 springV and caused to engage with the hasp.'` Thedog' G is made of, such form that when l elevated by thespring'l it closes tightly the opening through which the end of the hasp enters` thus preventing the entrance of foreign matters into the lock.

As a means of securing the bolt in itslocked position, I make use of a series of vibrating tumblers, N-such as shown in Fig. l-or sliding pin-tumblers in a rotating barrel, as shown in Fig. 2. Referring to the pivoted tumblers of Fig. l, they may be made of any ordinary construction. They may be pivoted to the case and arranged to engage with the bolt, or pivoted to the bolt and arranged to engage with a stud, o', formed on the interior ot' the lock-case, as shown in the drawings, the arrangement of these tumblers constituting no part of the present invention. As shown in the various figures, the lower end of thelockcase is deeply recessed around the key-hole. in order to permit the insertion of the seal-holding devices Ii therein. These devices consist, in the present instance, of a hinged lid or cover arranged to close upon the seal and hold the latter in position over the key-hole. The seal-holder is provided with a central opening through which to pass the key, this opening being closed, when required, by means of a hinged lid or door, XV. It will be observed that the recess in the lower end of the case causes the latter to extend downward on all sides around and beyond the scal-hold ing devices. This is an important feature, inasmuch as this depending edge serves, when the lock is suspended in its usual position, effectually to prevent the entrance of rain or snowinto the key-hole or seal-holding devices, thus avoiding the diiiiculty which is commonly experienced in this regard. In order to fasten the seal-holding devices K, I employ a dog or locking device of any suitable construction, operating by means of the same spring which elevates the dog G.

In Fig. 2 the locking device for the sealholder consists of the pivoted spring-actuated dog M, having a hooked end to engage automatically over the seal-holder when thelatter is closed. XVhen the hasp is closed, it serves to hold the sliding bolt G downward upon the rear end of the hook llI in such -manner as to keep the latter in engagement with the sealholder. In Fig. 7 the seal-holder is secured by a sliding spring-bolt, which is locked by means of an extended neck on the lower endl of the sliding dog G. In Fig. 8 the sealholder is pivoted at h and secured bythe end of the dog G, bearing thereon upon the top and in rear of the pivot. In Fig. 9 the seal-holder is arranged to slide upon its pivot, so as to engage at one end in a recess in the side of the case, and isprevented ,from disengaging by means of the dog G engaging in its end, as shown. A slight depression is made in the ease of the lock above the seal-holder to receive the seal,and pins are provided,both upon the body and upon the revolving barrel, to engage with the seal and insure the destruction of the Sallie when the barrel is revolved.

Instead of making use oli the vibratory tumblers represented in Fig. 1, I may employ, in connection with the barrel, the sliding or pin tumblers, similar to those employed in the well-known Yale lock.

The retraction of the bolt after it has been unlocked is effected by means ot' a stud or pin, b, mounted eccentricall y on the upper end ot' a rotating barrel or hub, F, mounted vertically in the center of the look and provided, as clearly shown in Fig. 11,)vith a longitudinal slit or opening, through which the key is inserted from the lower end of the lock, the key serving the twofold lpurpose of adjusting the tumblers and releasing the bail, and ot' imparting the rotary motion to the barrel F. It will ol" course be understood that, as in other locks of this class, the keyhole corresponding with the slit in the barrel is made in the lower end of the body. Inasmuch as it is necessary, after the retraction of the bolt, that the barrel shall be turned to its original position in order to permit the removal of the key, and the bolt meanwhileleft in its backward or unlocked position, so that the hasp may bc locked automatically when closed, it is necessary to provide means by which the bolt may be caused to re-engage with the stud b when the bolt is thrown forward to a locked position. The necessity for causing the bolt to re-engagc with the stud b upon moving forward arises from the fact that this engagement is the only means of preventing the bolt from being jai-red or driven backward out of engagement with the hasp. I therefore provide the bolt, as shown in Figs. 2 and 6, with a pivoted hook or dpg, '11, acted upon by a spring, and arranged to engage automatically with the stud. b on the barrel when the bolt is moved to alocked position. In retracting the bolt the stud acts upon the dog, or upon a shoulder, iz, formed on the bolt, as shown in Fig. 6.

For many of the purposes to which I propose to apply my lock it is highly important that provision shall be made for preventing it from being secretly opened by those who may be in possession of a suitable key. I therefore attach an alarm mechanism, such as shown in Figs. 12 and 13. This alarm consists of a bell, A, a vibrating striker or hammer, B', a pallet or escapement, O, to which the striker is attached, a rotating toothed wheel, D', by which the pallet is operated, and a coiled spring, E', by which the wheel is driven. The wheel is mounted loosely on a winding-arbor, F', and the spring is connected at one end with the arbor, and at the opposite end with the wheel, as shown. N ear the outer end the winding-arbor is provided with a ratchetwheel, G', which is engaged and held by means of a pawl, II. An arm, I', attached to the main lock-bolt, extends through the main body of the lock in such position that when the bolt is in its locked position the arm engages against the pallet and prevents its motion. Asupple- IOO IIO

mental case or shell, J', applied to the side of lock-body, covers and conceals the entire alarm mechanism,with the exception ofthe winding`- arbor, which protrudes as shown.

rIhe action is as follows: When the lock-bolt is thrown forward, the arm I rests against and holds the alarm, asl shown in Fig. 13. The spring is then wound by means of a key or equivalent device applied to the end of the protruding arbor. The parts remain quietly in this position until the lock-bolt is moved backward, whereupon its arm I releases the pallet and the alarm is at once sounded, giving audible notice to a considerable distance from the lock.

I am aware that padlockshave been recessed and provided with a key-hole in the lower end, and this I do not claim. In the lock rep- 'resented in the drawings, however, a peculiar relationship existsbetween theseal-holding devices and the recessed case, in that the case, extending down beyondthe seal-holding devices on all sides, serves the twofold purpose of protecting said devices against attempts to tamper therewith, and also against the admission of rain and snow, which would have the effectv scribed, whereby the bolt is permitted to re- `main inits unlocked position until the hasp has been closed, but locked rigidly after being moved forward.

'3. In a padlock, the combination of the swinging hasp, the main locking-bolt E, a sealholder, means for holding said seal-holder in a closed position, and a slidingbolt, G, adapted to serve the twofold purpose of preventing the unlocking of the seal-holder and of holding the main bolt in an unlocked position, said bolt G arranged to be operated by the hasp of the lock.

4. Ina padlock having the locking mechanisrn in one compartment and an alarm' mechanism in another compartment of the lock-case, the combination of the hasp-locking bolt provided with an alarm-'operating arm extending through the separating-diaphragm, with the alarm mechanism, substantially as specified.
