JULIUS M. COOK, OF HINSDALE, NEW YORK.

LOCK.

Specification of Letters Patent No. 17,424, dated June 2, 1857.

To all whom t may concern Be it known that I, JULIUs M. COOK, of Hinsdale, in the county of Oattaraugus and State of New York, have invented a new and Improved Mode of Constructing Locks, which I call Oooks Defiance Set-Lock; and I do hereby declare that the following is a full and exact description of the said invention, reference being had to the annexed drawings and to the letters and figures of reference marked thereon.

The nature of my invention consists of the bolt or bar (a) constructed with a cavity in square form upon one side suficiently large to admit of two small wheels, (Z2) and (o), a set (d) and fly e, which is made fast to a smooth plate of metal in such manner as to form a box containing the machinery, the bar and machinery sliding upon this plate, as the instrument is locked br unlocked. The wheels are const-ructed with a notch in the side of each, so as to admit the hook upon one end of the set (d), upon the entry of which the other end of the set is removed from the range of a lsmall stud j, upon the plate f, which allows the bar to slide at pleasure. In wheel is inserted a shaft, made firm to the wheel, this sha-ft being inserted through slide wheel o, at the center, through a round hole, suficiently large to allow it to turn easily upon the shaft, on which wheel is constructed a small spur near one edge of the wheel sufficiently far from the center as to come in contact with that portion of fly (c) opposite the notch or swallowtail end. The spiral spring is placed around the shaft (o), which presses against wheel c. The fiy being passed over the shaft of the set cl, is then put in place as represented in letter (a), the fly being indicated by the red dots.

The bolt a, with all the fixtures is placed upon plate and made fast by means of clasp (g) and (h), as represented by Figures 1 and 2 and letter F. The star, 7c, is then placed upon shaft (b), which completes the lock, to unlock which the operator places a key upon the end of shaft (el), as indicated in Fig. 1, and turns the key to the left once and a half around and bringing the point on the star which protrudes directly from the side of the square of sha-ft around to the degree on the dial opposite shaft (d). The first time the key is thus turned to the left the spur on wheel c is broughtinto contact with that part of Hy (e), as represented by letter f, which swings the dovetail end of the fly endward, and the next time the spur passes the dovetail will be in its track, and thus the motion of wheel c is stopped and wheel continues its motion until the notches in both wheels exactly correspond, which occurs at the same moment the above point in the star reaches the degree to the left of the crossed degree, the key is then turned to' the right, so that the above point of the star, 12 degrees on the dial to the right of the degree indicated by the dash or cross at the top. Also indicated by the little dot on the dial No. 1. At this point the notches in the wheels are brought opposite the hook (a) on the set, the key is then removed and placed upon shaft (cl) and turned to the left, by which means the hook n enters the notches in the wheels and the other end of the set is brought out of line with the stud upon the plate and allows the bolt to slide at pleasure.

To lock the machine the set is removed from the notches in the wheels and the key placed upon shaft (b) and turned once and a half at least to the left, and the notches in the wheels become displaced again.
