Specification of Letters Patent.

Patented Oct. 11, 1910.

Application led September 17, 1909. Serial No. 518,216.

To all whom it may concern:

Be it known that I, ROBERT BEAL REEVES, a subject of the King of Great Britain, residing at VVhitstable, Kent, England, have invented new and useful improvements in Padlocks, of which the following is a specification.

The present invention relates to improvements in padlocks and hasps therefor, and more particularly in that type of padlock which includes a rectilinearly movable shackle.

It comprehends generally a padlock construction wherein the formation of the main component parts is such as to insure their positive mutual coaction with each other and with the hasp, to the end that when the padlock is closed no opening will be left for the insertion of a tool between the shackle and hasp. This is attained by forming alining slots in the shackle and case through which the hasp may be passed, and by notching the latter in such a manner as to produce a pair or pairs of wings, adapted to exactly overlie the adjacent faces of said shackle and case, and to iit iiush against said faces.

A structural embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figures l and 2 are, respectively, front and side elevations of the improved padlock, showing the shackle closed upon the hasp. Figs. 3 and 4i are similar views showing the padlock removed from the hasp, and the shackle in open or projected position. Figs. 5 and 6 are, respectively, plan and side views of the hasp. Figs. 7 and 8 are, respectively, front and side elevations of a modified form of padlock, showing the shackle in projected position. Fig. 9 is a side elevation of a duplex hasp which may be employed.

Reference being had to said drawings, and to the letters marked thereon, A designates the case of the padlock and B the shackle. Said case is formed at its top with a rectangular slot E which opens through the front and back thereof and alines with an elongated rectangular slot C formed in the body portion b of the sliding shackle B. The el e ment B, in its preferred form shown 1n Figs. l to 4t, has an enlarged rectangular head portion b', the external dimensions of which are exactly the same as those of the top portion of case A, whereby each side face of said head will lie flush with the adjacent face of said case, when the shackle is closed, and the top face of the case will lit flush against the under face of said head b, thus precluding the insertion of a tool between the latter and the case at such time. rlhe slot C above referred to extends into the shackle head b, and when the shackle is open or projected, the length of the combined slot C, E, is but little greater than that of the head d of the hasp D, so as to permit the passage of the hasp head therethrough.

The shackle and hasp are each constructed of a single piece of metal, although the latter element may have a duplex formation, as shown in Fig. 9, being composed in such instance of two identical parts or members, each of which is of integral construction, said parts being arranged side by side. In either instance, the hasp has its opposite sides formed with alining rectangular notches F, the distance between the inner walls of which is exactly equal to the distance between the end walls of the combined slot C, E, when the shackle is closed. The effect of this notching is to produce wings Z2 at the ends of the hasp head el', and wings Z3 at the ends of the base Z of the hasp, said base having a length somewhat greater than that of said head, as shown. lVhcn the hasp is passed through the slot C, E, and the shackle closed, the front or head wings Z2 will lie flush against and extend across the front faces of the shackle and case, and the rear or base wings Z3 will, in like manner, lie flush against and extend across the rear faces of said shackle and base, as shown in Fig. 2, thereby completely closing the above mentioned slot and preventing the insertion of a tool thereinto, as will be apparent.

The shackle may be modified to the extent of omitting the enlarged head, as shown in Figs. 7 and 8, in which instance it will have a uniform width and thickness throughout. lVhile the double notch construction is deemed preferable, it may be stated that a single notch will insure, for some purposes, a sufliciently secure fastening of the shackle and case, and one of the notches may be accordingly omitted. Since the construction,

of said slots lying flush with each other; and a hasp arranged for insertion through said slots when the shackle is projected, said 15 hasp having head and base portions provided at their ends with Wings adapted to extend across and fit flush against the front and rear faces or" said case and shackle when the latter is closed.
