TO ALL WHOM IT MAY CGNCERN:

Bc it known that I, LEWIS I. DECKER, of Williamsburg, in the county of Kings, and State of New York, llave invented a new and useful improvement in Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, which 'will enable others skilledy in thea-rt t0 make and usethe same, refercncc being;r had to the accompanying drawings, forming a part of this specification, in which- Figure lis a side View of my improved lock, the cap or plate being removed.

Figure 2 i's a side vlewoF myimproved lock, the. cap or plate being removed and part being broken away to show the construction.

'llie object of my invention is to furnish a lock, safe, cheap, and'simple in construction.

And it consists, iirst, in operating the bolt of a lock bya screw second, in the combination of the female screw, male screw, and pivoted bolt'with each other,and with the body of the lock; third, in casting the body 'of the lock solid, with a cavity or channel cast therein Afor the reception of the operating parts; fourth, in the combination of a rubber packing with the bevelled or hollowed shoulder of the link, to prevent the access of water to the working parts of the lock to rust them when theV lock is exposed to the weather.

A is the body of the lock, which is cast solid, with a cavity or channel cast therein for the reception of the operating parts. B is the link, one end of which is pivoted in a notch formed in one end ofthe upper edge of the look in the ordinary manner. The shoulder b1 of the tongue or tennon [J2-of the link is bevelled or hollowed out around the base of said tongue, Z22, to receive the rubber packing C, which ts around the base of said tongue, and which, when the ,lock is closed, is compressed between the 'said shoulder, b1, and the body A of the lock, so as to prevent the ingress of water to the interior of the said lock around the tongue b2. A hole is formed throughthe tongue b2 for the reception of the bolt in the ordinary manner. D is the bolt of the lock, which is made curved, as shown in figs. 1 and 2, and is pivoted at its base to the forward end or head of the male screw E. The male screw E ts into the female screw F, and by the turning of said female screw is drawn in and out, operating the bolt D. Around thelower end or head of the female screw Fis formed a groove or neck, into which tits the edge of the collai or bar a1 to prevent the said screw from moving longitu dinally when turned to operate the bolt D. a2 is a bar tting down upon the head of the male screw E to hold.'

it in its place while being operated. These bars, al and a2, may be cast upon the under side of the plate G, if desired. The plate G ts into .a notch formed in the body A of the lock, and covers the operating parts of said lock. After the operating parts of the 'lock have been inserted'in'their place, the plate Gr is securely riveted to the solid body A of the lock. In the lower end or head of the female screw F are formed two holes, into which the prongs of the forked key H enter, and turn the said screw, operating the bolt D. The key H enters through a hole of the proper shape and size, formed in the lower edge of the lock body A, a suiiieient space being left between the head of the screw F and the lower end of the cavity in the body A for the fork or end of the key H to move through while seeking the holes in the head of the said screw F. The shank' of the key Il should be made small, so that -the key-hole may be small, rendering it very diiicult to pick the lock, blow it up with powder, or open it without the key that belongs to it. I have illustrated and described my invention as being applied to padlocl-ls, but it is equally applicable to all other kinds of locks.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent-- 1. 'lhccombination of the pivoted bolt D, male screw E, and female screw F with each other, and with the /body A of the lock, substantiallyas herein shown and described.

2. The combination of Vthe rubber packing C with the bevelled or hollowed shoulder b of the link B, substantially as herein shown and described. Y

The above specification of my invention signed by me ,this 29th day of August, 1866.

LEWIS P DECKER.
