ROBERT HAILE, OF CINCINNATI, OHIO, ASSIGNOR 'IO CHARLES DIEBOLD AND JACOB KIENZLE, OF SAME PLACE.
Letters Patent No. 104,020, dated J une 7, 1870.
HOM-:-
IMPROVEMENT IN SPINDLES POR SAFE-LOCKS.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern :v
Be it known that I, ROBERT HAILE, of Cincinnati, in the-county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Spindles for Safe-Locks; and I do hereby declare that the following is a full, clear, and exact description of' the construction and operation'ot' the same, reference being had to the annexed drawing making part of this specification. s
The object of myimprovement is to provide against certain detects, familiar to those skilled inthe art, in the construction of spindles for safe-doors, intended to be burglar-proof.
The objects usually attempted to be attained in such spindles are- First, a spindle thatcannot he withdrawn after the knob may have been broken o'.
Second, a spindle that cannot be driven into or through the sate-door.
Third, a spindle so constructed that it will, while being struck with the sledge, remain firm in its place, and therebyprevent a rebound of the spindle.
Among other forms of spindles that have been used to obviate thesedefects are a spindle having one or more shoulders, which brace against appropriate projectious in the door or back to prevent being driven in, a plain tapering spindle, and a spindle combining the features of the above two forms, that is, tapering in form from the outside to the inside, and having a series of small shoulders at intervals.
'lhe great disadvantage of the plain tapering form s-that it may be driven entirely through the safedoor.
. This disadvantage was intended to be remedied by the use of shoulders on the spindle, as above described, but while their use in the case referred to may obviate this inconvenience, they give no protection whatever against the spindles bcingwithdrawn from the front.
Ihe spindle which embodies my invention, and a perspective of which is shown in the annexed drawing, it is believed will remedy all these defects.
It is tapering in form, and has one or more s-piral grooves, A, cut upon its tapering surface. 'lhe grooves A have cutting-edges all along their surfaces.
lVhen the spindle. is struck witha sledge or hammer, after the knob is broken oil, the tendency of the taper form would be to actlike a wedge, and burst,'or otherwise find an entrance through the plates with which it is in contact. But, immediately upon its progression forward, in obedience to iron or other soft metal-plates for that purpose suit rounding it, until they become imbedded or fixed rigidly in the plates, and while continued blows from the and the impossibility of turning the spindle from the outsideit will ,be found impossible to drive the spindle wholly through the surroumling plates.
- 'Ihe drilling above referred to cannot be done with- S. S. Monats.
such blows, the euty Y ting-edges ot' the spiral grooves will engage with thesledge will have no tendency to cause a rebound, but,"- will, on the eontrary,lteud to make the spindle progress still further in, yet, from the form of the. grooves,
out first fixing or making the spindle fast by striking herein specified, will bind it so firmly, as before de.-
