REGISTERING LOCK.

.Q'PECXFICATION forming part of Letters Patent No. 452,438, dated May 19, 1891. Application filed September 2, 1890. Serial No. 363,786. (No model.)

To @ZZ whom it may concern: Y

Be it known that I, WILLIAM F. BEAsLEY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Registering Iiocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention consists in certain improvements in locks, and it more especially Vrelates to the same class thereof as that to which the patent, No, 220,124.granted September 30, 1879, to Henry Clarke,` belongs, upon which patent my present invention is an improvement, consisting in the following features designed to accomplish the hereinafter-mentioned objects. In order vto prevent the lateral bending of the shackle of the lock, (which has heretofore been made of brass, as that has been found most advantageous on account of the facility with which it may be worked,) I cast the metal forming the outside thereof around a central core of steel, which is elliptical in cross-section, the major axis of the ellipse being vertical. This core, which I by preference secure in place by lugs upon its sides', may be formed of hard steel, so that upon a bending of the shackle it will be broken, preventing a concealment of the injury, such as would be attempted by any one tampering with the lock who would desire to conceal his attempt, and it will be seen that the core will strengthen the hasp not only against lateral bending, but against an attempt to straighten it. I may also form perforations extending through the said outer casing and core, the said perforations being normally in line with each other; and it is obvious that if a hasp having these perforations is bent, on account of the compression of the outer casing upon one side andthe expansion upon the other, the perforations will no longer register, nor will there if the hasp be'bent in the opposite direction, thus straightening it, as the outer easing will slide upon the met-al of the core, leaving a ready means of ascertaining whether the hasp has been subjected to violence. In order to prevent the backward movement of the barrel carrying the shackle, which in this class of locks is objectionable, as it renders the register thereof useless, and in order to relieve the locking-pins proper of the barrel from strains attending resistance to such backward motion, I provide an independent pin engaging shoulders arranged upon the barrel at different points on the circumference thereof, one of the said shoulders on the barrel being so situated as to be engaged by the said pin upon the locking-pins dropping in their holes in the barrel. It will thus be noticed that much of the strain that has heretofore been borne by the locking-pins is now carried by the independent pin, which, as it does not enter any holes, may be made much heavier than the locking-pins and may be slightly bent without impairing its efficiency.

.My invention also consists in the construction, arrangement, and combination of the parts of which it is composed, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts are designated by similar letters, Figure l is a side View of a lock constructed in accordance with my invention, the casing thereof being removed and the shackle being in section and being also shown in dotted lines in a locked position. Fig. 2 is a section on line X X of Fig.

l. Fig. o is a section on line X X of Fig. l.

The barrel A is constructed in the manner as described in the said patent to Clarke and carries the indicating-wheels B thereon in the manner made known thereby, the post A', mounted on t-he top plate A2, carrying the train-Wheels B', which are also shown therein and now need no furtherdescription. The curved elliptical steel piece C (the major axis of which is vertical) is contained Within the shackle D, which is formed upon the upper end of the barrel A, it being secured therein vby lugs c upon its sides, which are held by the outer brass coating C of the shackle which is cast around the core C, the perforat-ions c passing through 'the core C and outer coating C', as is seen in Fig. 5. If the shackle be bent in the direction indicated by the arrows and subsequently straightened, it will be found that the holes no longer reg- IOO ister, but have the relative position shown in dotted lilies in Fig. 5, thnsall'ording a means ot detecting whether the lock has been tampered with. It will also be seen that it the steel is hard it will break if bent, thus giving additional evidence and at the same time Streu gthenin g the shackle against bending.

The projection E upon the top of the top plate A2 has a shoulder e upon the outer end of its top, the inner face of the said shoulder being inclined and overhung, as at e', while the lower surface of the free end el' the shackle has a shoulder cL2 upon its inner end, the outer face et the shoulder c2 being inclined to correspond with the inner face of the shoulder e. It will thus be seen that the said shoulders being engaged, as shown in dotted lines in Fig. l, it will be exceedingly diiicult to lift the end of the shackle in the direction indicated by the arrow in the said ligure, which would straighten it..

The collar F, secured to the barrel A, has a series of shoulders F F2 Fgin the upper end thereof, the said shoulders being on the circumference of a circle taken at right angles to the axis of the barrel, while a shoulder F1 extends entirely across the collar in the rear ot the shoulder F and the locking-holes f, the two latter being aligned, as seen in Fig. l, while a depression 7 is cut in the collar slightly in advance of the shoulder F', the said shoulders having rear square faces and inclined forward ones, the reverse being true of the depression.

In addition to the usual locking-pins f", which enter the locking-holes f, I provide an extra pin f2, (preferably of a greatersize than it is usual to make thelocking-pins,) which is housed in the aperture f3 in the housings f1 on the base of the top plate A2 and in the same plane as the shoulders F F2 Fis and depression f', with which the said pin is therefore adapted to engage. As the pin is aligned with the locking-pins, it will be seen that it will engage the rear squareface of the shoulder F when the locking-pins enter the holes .|f, thus relieving the locking-pins against any backward strain that may be exerted upon the shackle whilein a locked position, the pin f2 being held against the bottom of theshonlder by means of the usual spring ff. It the key be now inserted, the locking-pins will be forced outward, liberating the barrel, which may then be turned slightly in a forward direction (i. e., that of the arrow in Fig. 2) until the locking-pins fall behind the shoulder Ft, again locking the barrel against backward rotation, the end ot the shackle then having the position y. It the rotationbe continued, the pinf'? will engage the shoulder F9, or, 1f Vfurther continued, the shoulder F, the end of the shackle then bein g fy and y2, respectively. The rotation may be still further continued until the pin f2 engages the depression f', again locking the barrel against backward rotation, the end of the shackle being now at g/f". It the movement be still further continued, the locking-pins will fall into the holes f, while the pin f2 will engage the shoulder F', as has been described, the end of the shackle being now at y". I by preference so arrange the registering mechanism that the wheels will be actuated by the movement of the end on the shackle between i/1 and y, the latter point being at such a distance from the projection E that it will be impossible to release the hasp held within the shackle until the rotation has been registered. It will be seen that by this construction the locking pins are relieved from all strain against backward rotation,except in position fy, while the registering wheels are entirely relieved from strain.

Having thus described my invention, what l claim is- 1. A shackle composed of flexible material having a central core of brittle material therein, as described.

2. A shackle of flexible material having a central core ot brittle material therein, the said core having lugs upon its sides, as described.

S. A shackle consisting of an outer casing and a central brittle core and having perforations extending through the said parts, as described.

l. A shackle consisting of an outer flexible casing and a central brittle core of elliptical cross-section having lugs upon its sides, the said core and a casing having perforations extending therethrough, as described.

5. In a lock, the combination of a barrel having a collar thereon, the said collar having a shoulder extending across its surface and a series of independent shoulders upon its upper end extending around its periphery, pins locking the said barrel in position, and an independent pin engaging the said independent shoulders upon the collar, as described.

In testimony whereof I atlix my signature in presence of two witnesses.
