JAMES MCCLORY, OF NEW YORK, N. Y.

MODE oF coNsTRUcTING Locxs Eon THE Dooiis oEBANx-VAULTS. y' s f Specification of Letters Patent No. 787, dated June 19,

To all whom t may concern the city of New York, in the State of New York, have invented a new and improved mode of constructing locks for doors, andr which is well adaptedto doors for the vaults of banks and all 'other places where greatV represents the lock in perspective, the top plate being removed for the purpose of exhibiting the arrangement of such of the ,res spective operating parts as are thereby rendered visible, the other figures showing them in detail.

A, is the main bolt, which is made in the ordinary way.

B, is the bit, by which the bolt is to be moved backward and forward. This bit, which is in the ordinary form, is not to be withdrawn from the lock, but is to remain permanently within it, the pin C; making a part of it, and being adapted to receive the key D. Fig. 2 which is notched on the end of the pipe, as shown in the drawing, for the purpose of holding on to a projection or feather, on the pin or shank C, of the blt B, Fig. 1.

E, Fig. 3, is the tumbler which 1s to be raised by the bit B, in the usual way.

A slide F, Figs. 1, and 4, has on it a projecting piece G, which falls into notches on the upper side of the bolt, to hold it in place. It has also a projecting piece H, which passes into the notch H', on the tumbler, preventing the latter from rising to relieve the bolt, excepting the slide F, rise with it. This slide is furnished with flanches at its lower end, and these anches, and a part of the body of the slide are notched out as shown at I, I, I, these notches are t0 receive the cheek, or combination plates, Fig. 5, which slide easily within them; the ends a, a, of these combination plates are seen at a, a, Fig. 1. Notches on their sides numbered 7 and 15, are shown in the figure, these I call combination notches, the use of which will be presently explained. In the drawing Fig. 4, there are places for four such plates, but this number may be varied at pleasure. The plates fit indiscriminately into the respective notches in the slide, and the combination notches, on their own edges, are all made at dii'erent heights l from their lower sides. There are openings Be it known that I, JAMES McGLoRY, of

excepting when the boltA, is shot out, and y h stump M, is opposite to the notch in the 0 t. i i 3 i Fig. 8, are the nuts and cheek pieces which prevent the moving of the slide, Fig. 4L, Vexcepting when therouter ends c, of the cheek pieces are so situated that they coincide with the combination notches before named.

Fig. 9, is a screw shaft, which is toreceive the nuts and cheek piece, Fig.` 8, by turning which screws said nuts and cheek pieces are raised or lowered. The key, Fig. 2, fits on to the pin N, of this shaft, and serves to turn it. The projecting pins N, N, of four such shafts, are shown in Fig. 1, O, O, being a box in which they are contained, and which also sustains the bit B, and pin C, for moving the y bolt.

Fig. 10, is a cross section of the box, through one of the screw shafts P, having the nut 2, and cheek piece @,upon it. There is one of these nuts and cheek pieces to `each screw shaft; these slide up and down in openings between studs, or strips of metal, (Z, d. I sometimes form a square, near the lower ends of the screw shafts, and place a sliding plate R, R, upon the under side of the tumbler E, attaching it thereto by a pin, f which sliding plate allows the screw shafts to be turned when the square e, is within the curved enlargements shown on it, and prevents the raising of the tumbler when the squares are not so ranged as to pass into the narrower part betweenthem.- I frequently, however, omit this device, as not of great im` portance. The threads of the screws on the screw shafts are of such size as to bear aA known relationship to the numbers on the combination notches. Thus for example, if the cheek piece is at its lowest point on the loo screw shaft, fifteen turns, or half turns, of

When a spring bolt, and a spindlewith i knobs to turn it are used, have devised a` f new mode of regulating the length of the spindle between the knobs, so as to adapt it perfectly to the thickness of the door and lock; by which device I am enabled to cast the knob without an opening on its upper side, to receive a nut'. Fig. 11, shows a section of the knob, having the end l,of the spindle within it; g, is a nut which is put upon the endv of the spindle it, and which may be passed with it into the knob, through a cylindrical opening large enough for that purpose. A tube or collar, i, z', has a square hole through it fitting the spindle, and sliding on it; this collar is cylindrical on its outside itting the cylindrical opening into the knob-and it has a projecting pin y', which ts into a notch made to receive it on the end S, of the knob; a screw lc, Xed in the usual way, fastens the knob to the collar, or tube, Y

tion to the precise modeV of construction pointed out, but to vary the respective parts, in point of form, in any way which I deem proper, while the mode of action remains substantially the same, and

, Y I also declare that what I claim as my invention is-,-

l. The manner of arranging and combining the screw shafts, and their nuts and cheek pieces, with the combination plates, and the slide in which they operate, inthe manner, and for the purpose described.

2. I claim also, the so larrangingv and combining the shaft, vand the bit and pin, for turning the bolt, that the same simple key may operate, upon the whole whichkey, if lost, can be restored, and the lock opened, without resort to violence.

3. I likewise claim the manner of lengthening and shortening? the spindle of the knobbed handle, by means of the sliding ube,1 or collar, with the nut behind it as set ort Y JAMES MCoLoRY.
