IMPROVEMENT IN BOLTS FOR DOORS OF JAIL-CELLS.

Specification forming part of Letters Patent No. 155,105, dated September 15, 1874; application filed August 1, 1874.

.To all whom it may concern Be it known that 1, PETER J. PAuLY, of St. Louis, St. Louis county, Missouri, have invented a certain Improvement in Looks for Doors of J ail-(Dells, of which the following is a specification:

My invention consists in attaching the sliding bolts that look the cell-door to a lever, by which said bolts are operated, and the levers of a number of doors in a row are connected to a single sliding bar operated by a lever outside the corridor and inclosed within a locked case, so that the lever can only be operated (to lock or unlock the cell-doors) when the case-door is open. The operating-lever, when the cell-doors are locked, engages over a staple to receive a padlock.

In the drawings, Figure 1 is a front view. Fig. 2 is a plan.

A is the corridor, inclosed by gratingB upon the outer side, and the cell-wall G on the inner side. D are the cell-doors, hinged at E, and having a hasp-bar, F, by which each door can be secured singly. g g are bolts, sliding in cleats H, and connected to a vertical bar, Gr, having a link, 9, pivoted to the lower end of a lever, I, which is fulcrumed at i to the wall of the cell, and whose upper end passes through a notch or slot in the horizontal sliding bar J. The barJ extends from end to end of the row of cells. The outer end j of this bar extends outside the corridor into a locked case, K, and is connected to a lever, L, fulcrumed at l, and whose free end is slotted for the passage of a staple, and is secured by a lock, M. By this lever L the bar J, lever I, and bolts g are moved either to lock or unlock all the cells simultaneously. 7c is the door of the case K, said door being fitted with any desired kind of lock. The lever L or look M cannot be tampered with as long as the door It remains closed. N is the door of the corridor, the bolt 0 of which is arranged to slide into the case K, where it is secured by a padlock, P, passing through an eye in the end of the bolt.

It may be arranged, if desired, for the closing of the door to lock the corridor-door, and to hold it locked until the case-door is again opened. The opening of the case-door in this case would not unlock thecorridordoor, as this would be done by a separate action.

I claim as my invention- The cell-door D, bolts Gr g, cleats H, link 9, and lever I, in combination with sliding bar J, case K, lever L, and lock M, substantially as set forth.

PETER J. PAULY.
