AMOS S. BLAKE, OF WATERBURY, CONNECTICUT.

Latas Patent No. 84,162, dated Notember 1,7, 186s.

To all whom it may concern:

Be it known that I, AMos S. BLAKE,-of Waterbury, in the county of New Haven, and State of Connecticut, have 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 skilled in the art to make and use the-same, reference being had to the accompanying drawings,

'forming part of this specification, in which- Figure l is a side sectional View of my invention,

l taken in the line x a', fig. 2.

Figure 2 is a horizontal section of the same, taken in the. .line y y.

Similar i'etters of reference indicate like parts.

This invention relates to a new and improved lock,

inoperative, or incapable of being opened or unlocked on account of ice, objections which attend the use of the ordinary padlock;

In the accompanying sheet `of drawings, A represents what may be termed the frame of the lock, which is of curved form, as shown clearly in tig. l, and has a straight spindle, B, cast with orattached to it at its lower end, the upper part, ax, ofthe frame being curved in such a manner as to project downward in line with the centre of the spindle B, but at some distance' above it. A

C is a cup, which is fitted on the spindle, so that it may be moved up and down thereon, the. spindle having a rib, a, on its exterior, which is fitted in a notch,

`b, in the cup, the rib and notch preventing the cup from turning on the spindle. l

Within the upper part of the cup C there is fitted a catch or pivoted bar, D, which, when the cup is raised to its fullest extent, .proj ects over the opening in the lower part of theA cup, in which the spindle B l or bar D, having a tendency to keepthe latter in this position, as will be understood by referring to iig. 2.

. E represents a cone, the lower end or base of which is attached to the upper-end of the cup C. f

This cone is hollow the greater part of its length,.in

order that it may receive the spindle B, and said cone has a rod, d, fitted centrally in it, to serve as a keyguide, the spindle B having a key-hole, bx, extending through it its entire length, as shown in g. 1. Y When the cup C is fully raised on the 'spindle B, the upper end of the cone E is in contact with the end of the curved upper part ax of the frame A, the end of ax being made conical, to iit into a recess in the upper end of the cone.

When the cup and cone are thus elevated, as shown in fig. 1, the lock is in a locked state, the cup and cone being retained in that elevated position by the catch or bar D, which is turned aside by the key F, so that the cup and cone may be pressed down, in order to unlock the lock.`

This lock is extremely simple in construction, and cannot be damaged by water passing into it, nor be encased with sleet and ice in winter, so that it cannot be opened or unlocked, objections to which the ordinary padlock is liable.

Having thus described my invention,

I claim as new, and desire to secure by vLetters Patent- The frame A, provided with the spindle B, in combination with the cup' C, provided with the catch or.

bar D, or its equivalent, and the cone E, attached to the cup, allbeing constructed and arranged substantially as and for the purpose specified.
