Description
ADDISON CROSBY, OF VVESTFIELDNEW YORK.
Letters Patent No. 91,610, dated June 22, 1869.
nyrpacqv'ElviaNT n v PaDLocxs:
The Schedule referredto in these Letters Patent and making part of the same.
To all whom 'it may concern:
Be it known that I, ADDISON CROSBY, of Westfield, in the county of Chautauqua, and State of New York, 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 vertical section of my invention, taken in the line x x, iig. 3 c
Figure 2 is a vertical section of the same, taken in the lineyy, fig. 3.
Figure 3 is a horizontal section of the same,'taken in the line z z, fig. l.'
Figure 4 is a detached perspective view of the key. Similar' letters of reference indicate like parts.
This invention is designed as an improvement upon the ordinary padlock, whereby simplicity is obtained, with security, or difficulty in picking or illegitimately opening the lock, while the interior of the same is protected from moisture, and prevented from being choked or clogged up with sleet or ice during the winter-season. Y
In the accompanying sheet of drawingsp A represents the case of the lock, and
B is, the bow, or shackle, which works up and down, said bow or shackle having a straightrportion, a, which works within the case, as shown in gs.l and 2, a spiral spring, bwithin the case, throwing the shackle upward wheneverit is released from dogs,
which retain or hold'. it down in a locked position or` state.
C C are the Vdogs which are' fitted loosely on an arbor, D,within the case.
Said dogs have springs o attached,'which springs have a tendency to keep they lower ends of the dogs in a notch in the straight portion of the bow or shackle, in order to hold the same in a locked state. (See more particularly fig. 2.)
E represents the tumblers, four being shown in the drawings, two at each side of the dogs.
These tumblers are suspended by pivots ax, and have oblong curved slots dmade in them, through which the arbor D passes.
The lower edges of the tumblers are notched, orv
serrated, and each has an upright slot, e, made in it, said slot being at diierent points inthe several` tume blers.
The dogs O Ov have each an arm, F, pivoted to th in, and these arms extend. down at the outer sides oi'i he tumblers, and have each a small bar, dx, projecting from them at right angles, said bars extending underneath the tumblers. v
" I claim as' new, and
The lower parts of the arms F work between guidepins eX eX, which keep them in place. (See fig. 2.)
From the abovel description it will be seen, that in order to unlock the lock, the lowerends of the dogs C C must be thrown out of the notch in the upright straight part a of the bolt or shackle, and, in doing this, the arms-F will necessarily be raised, and conse.
openings in the bottom of the lock-case, and the bitsV g g irst adjust the tumblers E E, so as to bring the .slots e in the several tumblers in line with each other,
and the ends of the prongs ff then come in contact with the upper ends of' the dogs O C, and throw the lower ends of the latter ont from the notch in the straight part a oi' the bow or shackle B, and the spring b then throws the latter upward.
The tumblers are provided with springs h, to give A,them their return movement, as the prongs ofthe key are withdrawn.
VIt will be perceived that the lower edges of the Ytumblers E havea wide movement, or sweep, compared with the movement or sweep at the points bx, where the bits g of the key act against them, and hence it will beseen that it would be a very ditlicnlt matter, if not utterly impossible, to adjust the slots @of the tumblers `in line'with each other by any illegitimate means, foi-*the 'slightest movement of the tumbler at V`b ,`will cause the lower edges, where the slots e-are made, to move a considerable distance.
I t willfurther be seen that the lower parts of the tuniblers'are in such a position that they cannot be reached and-acted upon by picks, and tampered with. desire to secure by Letters Patent'- l 4 V1. The rising and falling bow or shackle B, in con` nection wit-h'the dogs C, thertuinblers E, provided `withthe slots e, andthe arms F, having the bars ZX attached, all-arranged to' `operate in the manner subst-antially asiand for the purpose set forth.
, 2. lhe key G, provided with two prongs f j, having .lateral bits g g, when used in connection with the tumblers E and dogs C, all arrangedl to operate substantially as and for the purpose set forth..
