UNITED STATES JOHN A. MCMILLEN, OF SAN FRANCISCO, CALIFORNIA.
SPEGI FIGATION forming part of Letters Patent No. 688,747, dated December 10, 1901.
Application filed July 12,1901.
To all whont it may concern:
Be it known that I, JOHN A. MOMILLEN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Safety-Hasps, of which the following is a specification.
My invention relates to an improved safetyhasp, the object of myinvention being to provide a device of this character which will insure greater security than heretofore, rendering it extremely difficult to remove the staple used with such hasp from the door or other part to which it is attached. To attain this object, I provide an improved form of hasp which will render it practically impossible to insert a chisel or similar tool in the eye of the staple to prize the same from its support or to remove the staple by prizing the hasp itself or to obtain access to the staple with a pair of nippers to cut the same.
My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claim.
In the accompanying drawings, Figure 1 is a perspective view of the hasp and staple c011- nected to each other. Fig. 2 is a similar view showing the padlock removed, and Fig. 3 is a similar view showing the hasp and staple disconnected.
Referring to the drawings, 1 represents a hasp'having hinged thereto a socket-plate 2, provided with countersunk holes 3, by means of which the plate can be attached to the door, jamb, lid, cover, or the like. It will be seen that when the hasp is secured to the staple the holes 3, and therefore also the heads of the nails or screws through said holes, are hidden by the hasp 1. Said hasp has hinged at its free end a cover-plate 4:, which has the usual hasp-eye 5, arranged to pass over the staple 8, said plate 4 also carrying, either cast integral therewith or otherwise secured thereon, a hood 7, which is adapted to lie over and cover a staple 8, secured to a'staple-plate 9, provided with holes 10, by means of which the Serial No. 68,122. (No model.)
same may be secured to the jamb by nails or screws through said holes. The hood 7 is of the form of an inverted elongated bowl, the lip or rim of said hood being attached to the hasp and completely surrounding the aperture therein and has substantially midway of each side an aperture 11, said lateral apertures thus being in the proper position to re ceive the shackle of a padlock when said shackle abuts against the upper or middle portion of the staple. The apertures are substantially the same width as the staple, so that said shackle almost fills said apertures, and it is impossible to insert in said apertures a sufficiently large instrument to prize the staple off. In the ordinary form of hasp and staple-fastening it is comparatively easy to forcibly break open the same by inserting a chisel or similar tool in the eye of the staple and prizing the same from its support. By means of this invention this is prevented, since it is not possible to insert through the aperture 11 an instrument of sufficient power to prize the same loose. Moreover, it is not possible to insert a chisel underneath the hasp itself to prize the staple off, nor is it pos sible to cut the tines of the staple with a pair of nippers.
I claim- A safetyhasp having hinged thereto a socket-plate adapted to be attached to a door or the like, the free end of said hasp being apertured and having secured thereon a hood of aninverted elongated-bowl shape, and con formed to fit snugly over the staple, the lip or rim of said hood being attached to the hasp and surrounding the aperture completely, and said hood being apertured substantially midway of each side, said lateral apertures thus registering with the upper portion of the eye of the staple, substantially as described.
In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
J. A. MOMILLEN.
