RUDOLPH RICHTER, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF HIS RIGHT TO JOHN E, THOMAS, OF SAME PLACE.
IMPROVEMENT IN dPERATING PRISON-DOORS Specification forming part of Letters Patent No. 170,400, dated November 23, 1875; application filed October 21, 1875.
To all whom it may concern:
Be it known that I, RUDOLPH RICHTER, of Indianapolis, in the county of Marion and in the State of Indiana, have invented certain new and useful Improvements in Prison- Doors; and do hereby declare that the followin g is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.
My invention relates to mechanisms for opening and closing doors for cells in jails or other prisons; and it consists in the construction and arrangement of mechanism whereby the guard from the guard-room can open and close any one or more, or all cell-doors, as desired, and also open and close the vestibule and inside doors at will, as hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 shows the guard-room, vestibule,
. and inside doors and mechanism connected therewith. Fig. 2 shows one side of the cellroom with the mechanism connected with the doors of the cells. Fig. 3 is a bottom view of the mechanism connected with the various doors. Fig. 4 is a detached view of a part of the mechanism.
A represents the guard-room of a jail or other prison, in which the mechanism for opening and closing the various doors is situated. B B represent the doors of the cells, each of which is securely fastened to an upright rod or shaft, at, having suitable bearings on the outside of the door-casing. The shaft a extends downward for a suitable distance through the floor, and rests in a step, b. On the lower end of the shaft a is placed loosely a cogwvheel, O, and immediately on top thereof is a disk, D, secured to the shaft. On top of the disk D is a frame, in which is placed a vertical pin, 01, having a flange or collar, 6, beveled on its under side, as shown in Fig. 4. The lower end of this pin passes through a hole in the disk D, and is to drop of its own weight into a hole, a, in the cog-wheel G. This cog-wheel gears with a horizontal rack-bar, E, into which also the cog-wheels connected with all the cell-doors B are meshed. This rackbar extends the entire length under the cellroom and under the guard-room A, where it meshes with a cog-wheel, G, upon an upright shaft, f, which extends upward into the guardroom, and has a handwheel, H, secured upon its upper end. I represents a T-shaped lever, pivoted at the junction of the three arms, and the inner arm is forked to pass under the beveled flange e on the pin d, when the disk D is turned to a certain point. the lever I has a projection, 73, extending under a vertical sliding bolt. h, placed in the door-casing at the outer end of the door. This bolt has two or more books, 3 which enter slotted-or mortised ears It It, that enter holes in the casing when the door is closed, the bolthooks thus locking the door. The lower or middle arm of the lever I is, by suitable connecting-rods m m and elbow-levers n a, connected with an upright rack-bar, J, in the guard-room, where said rack-bar is placed in suitable guides, and operated up and down by means of a cogged lever, K.
Each and every door B is provided with a mechanism precisely the same as above described, with the exception that only one rackbar, E, is necessary for all the cell-doors on one side of the cell-room.
The operation of this part of my invention is as follows: The doors B being all closed and the bolts h down by their own weight, the levers K are turned down to raise the rackbars J, which causes the levers I to turn on their pivots, so that their inner ends will raise the pins d out of the holes .19 in the cog-wheels 0, thus disconnecting the doors entirely from r the operating mechanism. By raising one or more of the cogged levers K, the corresponding T-shaped levers I will be turned so as to simultaneously raise the bolts h by their projections i, and connect the corresponding doors with the operating mechanism by allowing the pins d to drop into the holes a on the cogwheels 0. By now turning the hand The outer arm of v wheel H on the shaft or stafl'f, the doors thus connected with the operating mechanism will be opened.
By a reverse motion of the parts these doors a. are closed and locked.
It will thus be seen that the guard can, from hisplace in the guard-room, open and close any one or more, or all, of the doors at one time. i
L represents the vestibule-door, and M the inside door. The inside door M slides upon rollers, and has at its lower end, below the floor, a rack-bar, 12, attached to it, which gears. with a cog-wheel, N, placed loosely upon the, shaft s, to which the vestibule-door L is secured, and by which it is hinged. To the shaft s,'immediately above the cog-wheel N, is secured an arm, 0, with a frame on the outer end, in which is placed a vertical pin, (1, with beveled collar or flange e, to drop down of itsown weight into a hole, as, "in the cogwheel N, when both doors L and M are closed.
When in this position the forked end of a .piv
oted lever, I, passes under the beveled flange or collare of the pin 01, this end of said lever being made the heaviest, so as to .hang down and not raise the pin. Within the'guard-room A is a vertical sliding bar, P, which, when moved downward, strikes an arm, t, project ing from a rocking bar, '0, and another arm," w, projecting from the samierocking'bar, bears down on the outer end of the lever I, thereby raising the pin d out of the hole in the cogwheel N. The doors L and M may then be opened independent of each other. At the side of the sliding bar I is another sliding bar, P, which, when the door M is closed, is pressed down and enters a hole, 2, in the cogwheel N, and locks the same. On theshaft f,
2. The combination of .thedoor B, shaft a.
disk D, pin (1, with beveled flange e, and cog-. wheel 0, with hole as, as and for the purposes herein set forth.
3. The combination, with aseries of doors,
B, and mechanism for connecting the same with the cog-wheelsO, of the rack-bar E, wheel G, shaft f, and hand-wheel H, substautiallyas and for the purposes herein set forth.
4. The combination, with the door B, shaft a, disk D, and 'pin d, of the lever I, connections m a, rack-bar J, .and cogged lever K,
substantially as andfor the purposes herein setforth.
5. The combination, with the doors L of the rack-bar p, cog-wheel N, shaft 8, with arm 0 and pin (1, lever O, sliding bars P P, and
rockingbar o, with arms t 14;, substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 7th day of May, 1875.
RUDOLPH RICHTER.
