IMPROVEMENT IN PADLOCKS.
Specification forming part of Letters Patent No. 171,471, dated December 28, 1875; application filed June 16, 1875.
To all whom it may concern:
Be it known that I, GEORGE R. OUTBIRTH, of San Francisco city and county, State of California, have invented an Improved Padlock; and I do hereby declare the following description and accompanying drawings are suflicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.
My invention relates to an improved padlock; and it consists in providing a circular bolt of peculiar construction inside of a circular case or shell, and also in placing a rotating cap upon a shaft over the key-hole, inside of which two or more disks are arranged to serve as guards to close and protect the key-hole.
Referring to the accompanying drawings, Figure 1 is a side sectional view of my lock. Fig.2 is an outside view. Fig. 3 is a transverse vertical section. Fig. 4 is a detail view of the several disks or guard plates. Fig. 5 is a modification of the bolt.
A is a circular case, having the hasp B pivoted to a lug, G, at one side, so that its opposite end will pass through a hole or opening into the case, as shown. The bolt which secures the hasp when it is closed is made circular so as to fit inside the case A, while the key enters through one side of the case and operates from the center of the bolt to unlock it. The bolt consists of three main .pieces, namely, a round rod, f, which is bent into a circular form, and the two pieces G H, which are secured to the endsof the circular rod f. The piecesG H are made in two sections, and are cored out on their meeting faces, so as to allow the end of the rod f to enter between them, as shown at i. The core or grooved extends from one end of the pieces GH to near the opposite end. A shoulder, j, is formed on the rod f, and a spiral spring, K, is secured over the end of the rod, so that one end will bear against the shoulder.
When the end of the rod has been placed in the groove of one of the pieces, the spring K is condensed or crowded into the groove, so that its outer end will press against the metal at the closed end of the groove. The opposite piece is then placed upon the first one, and
slot in the end of the hasp,
the two are then secured together so as to reboth ends of the rod f, and it will readily be seen that as the curve of the grooves in the pieces are identical with the curve of the rod f, a pressure on the adjoining ends of the pieces will force them apart by compressing the springs K and causing a telescopic movement of the rod in theunited pieces. This circular bolt when thus put together is just large enough to fit inside the circular case A, the opposing ends of the end pieces G H coming opposite the opening in the case, through which the end of the hasp B passes.
The end of the piece G has a lug or latch, m, formed on it, which passes through the when it is pressed through the opening in the case and between the end pieces, thussecuring the hasp in its locked position. Lugs n n, which are formed on the lower corner of the outer ends of the pieces G H serve as fastenings for the extremity of toggle-arms 0 0. These arms extend downward toward the key-post, so that when thekey is inserted and turned in the lock, it will force the toggle-arms upward, and thus cause thein'to press the pieces apart and free the hasp. One or more disks or tumblers, p, can be secured around the key-post inside of the circular bolt if desired. This circular bolt can also be set in the jamb of a sliding door, so that a projecting tongue or stationary bolt on the door'will enter between the end pieces and be secured in the same manner as the hasp.
To protect the key-hole I employ a rotating cap, which turns on a post at one side of the key-hole, and has a key-hole in it. Between this cap and the face of the lock ll insert 'one or more circular disks, 8, each of which is provided with a key-hole. These disks are connected by pin and slot in the manner of connecting the disks of a combination lock, and the upper one is connected with the rotating cap Q. By rotating this cap in one direction the disks will be disarranged, so that the keyhole in each plate is covered by the plate above it, but by turningin an opposite direction the key-holes are all brought into line, and the key-hole exposed, so that the key can be inserted to unlock the bolt. Two turns of the cap are sufficient to bring the key-holcsin line so that the key will enter through them. The object of these disks is not so much to provide a combination as to render the lock troublesome to open by a person not familiar with its operation and also to completely guard the key-hole from the entrance of dust, snow, or rain.
By this means I provide a strong and durable padlock, which will be especially adapted for securing heavy doors.
Having thus described my invention, what I claim, and desire to secure by Letters'Patout, is-
1. The circular bolt, consisting of the rod hollow end pieces G H, and spiral springs K, substantially as and for the purpose above described. I
2. In combination with the case A the rotating cap Q and series of rotating disks 8, each of which is provided with a key-hole, and the whole connected by pins and slots, substantially as above described.
In Witness whereof I hereunto set my hand and seal.
