This item is printed on demand. Paperback. 200 pages. Dimensions: 9.7in. x 7.4in. x 0.4in.This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1856 Excerpt: . . . friction-roller may also be applied to the bolt, and have fixed recesses; and it is not absolutely necessary that the recesses should be used, as the roller may be caused to rise and fall over a check-stop or bar. Thomass Prison Lock, invented about 1842. This lock, invented by Mr. Thomas, of Birmingham, contains a common tumbler, a bolt, and a brass guard-flap--the latter retained in its position by a spring inserted at the back of the lock. The key in its revolution lifts the guard-flap at the same time that it acts upon the tumbler, and throws the bolt. The lock has also a handle on the outside attached to a trigger, which catches the bolt when shot back by the key in opening the door, and retains it until the handle is touched, which puts the bolt on half-lock. This contrivance, the object of which is intended to save the time of the turnkeys, places the bolt in such a position, that on closing the door from the inside, the lock can only be opened by the application of the key from the outside. According to the rules of the Pentonville prison, where these locks are used, every prisoner is obliged to touch the handle of the trigger, and so shut himself into his cell. There is nothing very novel in the construction of this lock, neither does it possess any real security, its only recommendation appears to be its cheapness, the price being but ten shillings. It certainly cannot be picked from the inside, as there is no keyhole, and the escape of prisoners from the above prison some months ago was not effected by picking the locks. Acbins Latch-bolt, invented about 1842. This improvement in the construction of leverlatches consists in placing the latch-bolt at the back of the levers, thus making it almost impossible to reach the bolt by any surreptitious . . .
