On the Construction of Locks and Keys by John Chubb
CONSTRUCTION OF LOCKS AND KEYS.
The following letter has been received from Lieut. Tracey, Governor of Westminster Bridewell, and is submitted as a testimonial in favour of the security and durability of Chubb's Patent Locks, and their consequent applicability for prisons, or other places, in which those qualities are requisite.
" House of Correction, Westminster, " SIR, "March 11, 1850.
" IN reply to your communication of this morning, I have no difficulty in stating my entire approval of the locks prepared by you, and in constant use in this large prison. Very many are necessarily exposed to the weather, from being fitted to the entrances of the several buildings, and although in constant wear, they have proved both secure and capable of resisting wet. I am of opinion, after an experience of nearly sixteen years, that your locks are admirably adapted for every use in prisons, and wherever security is deemed an important consideration.
«I am, Sir, " John Chubb, Esq., " Your obedient Servant,
" St. Paul's Church Yard." " AUG. FRED. TRACEY, Governor,
