SPECIFICATION forming part of Letters Patent N 0. 477,301, dated June 21, 1892.

Application filed September 7, 1891. Serial No. 405,016. (No model.)

To all whom it may concern;

Be it known that we, PERLEY HALE, of Chicago, in the county of Cook and State of Illinois, and CHARLES H. SPARKS, of St. Louis, Missouri, have invented certain new and useful Improvements in Electric Jails, of which the following is a full, clear, and'exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to improvements in electric jails and electric-alarm mechanism for the same; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described,and designated in the claims.

Fig.'17 is a diagrammatical viewof anet-work of electricwires conceived to traverse the sides, ceiling, bottom of a jail, a cell, or a corridor. Fig. 18 is a detail view of a modified form for the ceiling or floor of a jail, cell, or corridor, showing the electric wires traversing the same. a detail View of the ceiling or floor of a 'cell, jail, or corridor which we preferably use, showing a series or net-work of electric wires traversing the same. Fig. 20 is a diagrammatic view of the electric alarm mechanism, showing the same applied or in connection with the jail, or especially the doors thereof, and showing the mannerof producing an alarm by the opening of the cell-door. In said figure two cells, two doors, and a corridor are shown. net-work of electric wires conceived to traverse a cell-door of any desired construction, and also an electric switch; and Fig. 22is a diagrammatic view of a similar net-work-of wires conceived to traverse a cell-door, showing an electrical connection formed from the rear part of the door or the portion of the door which is hinged to the cell-wall.

The object of our invention is to construct a certain form of jails adapted for the passage of electric wires through the same, and through the cells or corridors thereof, so devised that an alarm is produced whenever the prisoner cuts any aperture in the exterior walls of said jail or floor or ceiling of the same, in the cellwalls or floor or ceiling of the same, or in the corridor or doorsinitiatory for escaping. We also show, as will be more f ull'y hereinafter described, an electric construction for celldoors, wherein an alarm is produced by the opening of the door by any unauthorized person. WVe accomplish this object by passing an electric current either through the metallic construction of the cells, doors, or corridors, or, preferably and more feasibly, through a system of wires located in the metallic construction and having said metallic construction'or system of wires in suitable electrical connection with an alarm mechan- Fig. 19 is Fig. 21 is a diagrammatic view of a too tric alarm mechanism for jails, whereby an alarm is produced when the circuit is broken. However, We may extend a similar principle of construction so as to produce an alarm when the circuit is closed.

\Ve will first give an explanation of the mechanical construction of the cells, and in connection therewith the location of the electric wires which traverse the same.

Referring to the drawings, 1 indicatesa series of vertical gratebars, which are formed of heavy sheet metal, bent in U-section, as illustrated in Fig. 3, having a filling-plate 2 between the extreme ends of the U and extending throughout the entire length of the vertical bar 1 and projecting beyond the terminal ends thereof, as illustrated in Fig.1. Said filling-plate 2 is secured in the vertical bar 1 by means of rivets 3 or in any other suitable and mechanical manner. The fillingplate 2 does not extend the full depth, but leaves a space or channel in the grooved side of the U-seetion for the passage of electric wires.

4 indicates a base-plate, which is secured to the floor 5 of the cell in anysuitable and mechanical manner, and to said plate 4 the filling-plate 2 is secured in any suitable and mechanical manner; or, if necessary, both the vertical bars :1 and the filling-plates 2 may be secured to the base-plate 4. It may be noted in this connection that the upper ends of the vertical bars 1 and the filli-ng'plates 2 may be similarly secured to the ceiling of the cell. We may, however, dispense with the basepl-ate4 and secure the vertical bars 1 and filling-plates 2 directly to the bottom 5 or the ceiling of the cell,bearing in mind to leave a channel for-the passage of electric wires. The base-plate 4 is provided on its lower surface with a substantially- U shaped groove or channel 6 for the passage of the electric wires.

The horizontal grate-bars consist of two pa-r'tsviz., a lock-bar 7 of the construction as illustrated in Figs. 41 and 5, and a key-bar 8, as illustrated in Fig. 6. The key-bar 7 is provided with a longitudinal V-shaped groove extending throughout its entire length, and the lock-bar 7 is in cross-section asnbstantially-truncated sector of a circle and is provided with a series of depressions or recesses 9, in which the filling-plates 2 are adapted to fit. The vertical bars 1 are provided with a series of circular perforations 10, and the filling-plates 2 project in the same when in use, as illustrated in Fig. 2. By referring to Fig. 2, and especially to the cross-section of the key-bar and lock-bar, it can be readily perceived that when the lock-bar 7 is located in the V-shaped groove 11 of the key-bara channel 12 is formed between the truncated base of said lock-bar and the innerapexial surface of the V-sha'ped groove 11, and in said channel 12 the electric wires may be located, through which the electric circuit may pass through the series of horizontal wires of the grating. It can be deduced from the foregoing description that when the lock-bar is located in perforations and the fillingplates 2 inserted in the recesses 9 of said lockbar the same is prevented from any horizontal movement.

In Fig. 7 we show a tubular horizontal grate-bar with the electric wire located therein, and in Fig. 8 we show said tubular horizontal bars 13, provided with recesses 14:, in which the filling -plates 2 are adapted to snugly fit, and consequently prevent any horizontal movement of said tubular horizontal bars.

In Fig. 9 we show a modification of a lockbar 15, the same being rectangular in crosssection and provided with aseries of recesses 16,in which the filling-plates 2 may be inserted.

In connection with modified lock-bar we employ a modified form of key-bar 17, the same being provided with a deepened U- shaped groove 18, of greater depth than the width of the lock-bar 15, so as to permit the insertion of an electric wire between the same.

In Fig. 11 we show a modified form of the.

ing-plate 20, illustratedin Fig. 11, we em-.

ploy the same key-bar as illustrated in Fig. 6 and a modified construction of the loelcbar illustrated in Fig. 14, wherein said lock-bar is provided with a series of perforations 21, in which the tongues 19 are adapted to fit.

Fig. 13 illustrates, or more specifically is, a cross-section of the key-bar as illustrated in Fig. 6 and the lock-bar asillustrated in Fig. 14:, the said section beingtaken through perforation 21, and also shows an electric wire located between the apexial inner surface of the V-shaped groove 11 of the key-bar and the truncated surface of the lock-bar.

Fig. 12 is a top plan View of the construction as illustrated and described in Fig. 11.

In Fig. 16 we showa modified tubular grating, which is preferably constructed of gas-v pipes, and Fig. 15 is a sectional. view showing the manner of connecting the vertical and horizontal tubular grate-bars, and also shows electric wires passing-through the same and crossing each other. In this construction of grating we pass the electric wires directly through the bores ofthe tubular grate-bars.

Having given a'description of the mechani- ITO cal construction of the cell-gratings, we will now proceed to describe in consecutive order, first, the electrical appliances, which produce an alarm when the cell-door is opened by any one except an authorized party, referring to Figs. 20, 21, and 22, which are diametrical views, for illustration.

25 and 26 are outline views of cells. 27 and 28 are their appropriate doors, respectively, the door 27 being open, as shown in dotted lines. Itcanbe readily perceived by referring to Fig. that the views are only out lined', as the mechanical construction of the doors is immaterial to the understanding of the invention, said construction being of the bar form shown and described herein.

29 indicates an outline view of the jail-corridor, which is adjacent to cells and 26.

In order to fully comprehend the diagrammatic view and the electric construction, as illustrated in Fig. 20, it is necessary to refer to Fig. 17, which is a diagrammatic view of electric wires which traverse, or, rather, are conceived to traverse, the walls, ceiling, and floor of a jail, cell, or corridor. Wire 30 traverses the remaining two sides, as illustrated in Fig. 17, and bottom of the cell, and connects with wire 47, thus forming a complete circuit around the walls, ceiling, and bottom of the cell. The direction of the current is illustrated by arrows 32.

\Ve will now refer to Fig. 20. The wires 30 and 47 traverse the cells outlined in Fig. 2O similarly to the diagrammatic view illus trated in Fig. '17, and wire 30 is connected to a metallic contact-point 33, located above and to the right of door 28 in Fig. 20. Wire 47 is connected to a metallic contact 34, located above door 27.

Figs. 21 and 22 are diagrammatic views of the electric wires which traverse, respectively, doors 27 and 28. indicates an electric wire, which passes vertically upwardly and downwardly and alternately in door 27, and also traverses the same door in a similar manner across the same, and one end of said wire is connected to metallic contact-piece 36 and the opposite end to metallic contact-piece 37. Metallic contact-piece 36 comes in contact with metallic contact-piece 34 when door 27 is closed, and metallic contact-piece 37 comes in contact with metallic contact-piece 38, also when door 27 is closed. You will first, in order to trace the current, conceive door 27 to be closed and the contact-points 38 and 37 in electrical contact and the contact-pieces 34 and 36 also in electrical contact. The current will then pass through wire 30 in direction of the arrow 39 into themetalic contactpiece 33, which isin electrical contact with the metallic contact-piece 40 when door 28 is closed. The current from metallic contactpiece 40 passes into wire 41. (One end of said wire 41 is connected to metallic contactpiece 40, and the opposite end of said wire 41 is connected to a metallic contact-piece 42.)

The terminal portions of wire 41 are located in a pipe 43,-which is secured to door 28 in any suitable and mechanical manner and is movable therewith. Said pipe 43 is provided with a horizontal arm 44. Metallic pieces 33 and 40 are in electrical contact when the door 28 is closed, and metallic contact-piece 42 is also in electrical contact with a metallic contact-piece 45 when door 28 is closed. The wire 41 traverses the door 28 horizontally and vertically across the same, as illustrated in Fig. 22. The current then passes through wire 41 into metallic contact 42, and from metallic contact-piece 42 it goes into metallic contact-piece 45, and from metallic contactpiece 45 it goes or passesthrough wire 46, and from wire 46 it goes into metallic contact-piece 38, thence into metallic contact -piece 37, thence through wire 35, which traverses door 27, thence into contact-piece 36, then through wire 47, one end of which is connected to metallic contact-piece 34 and the opposite end thereof is connected to the negative pole of battery 48. The positive pole of battery 48 is connected to one end of the wire of the electro-magnet '49 by means of a wire 50 and the opposite end of said electro-magnet wire is connected to Wire 30. Pivotally mounted above said electro-magnet 49 is a pivoted armature 51, which is elevated by means of a spring 52. Said armature 51 is provided on its under surface with a lug 53, which is adapted to come in contact with the core 54 of the electro-magnet.

55'indicates an alarm-bell of ordinary construction, one pole of which is connectedto one end of awire 56 and the opposite end of said wire 56 is connected to a metallic contactpoint 57. The other pole of said bell 55 is connected to one end of a wire 58 and the opposite end of said wire 58 is connected to the positive pole of the battery 59. The negative pole of said battery 59 is connected to one end of a wireGO and the opposite end of said wire is connected to a metallic contact-piece 61. The upper surface of the armature 51 is provided with lugs 62 and 63,which are adapted to come in contact, respectively, with the contact-pieces 57 and 61. Mean be readily perceived from this construction that while the current is passing through the'electromagnet 49 the alarm-bell circuit will bebroken; but when no current passes through the electro-magnet 49 the armature 51 will be released and pulled upwardly by spring 52 and complete a circuit through the alarm-bell circuit, and consequently the alarm will be made. It may be noted in this connection that the electro-magnet 49 and the alarm-bell 55 and the electrical connections between the same may be located at any suitable distance from the cells. It may also be noted in this connection that whenever any of the bars which traverse the cell-walls or doors, ceiling, or bottoin of the cell, which are in connection with wires 30 and '47, are severed by the prisoner the current which passes through the electroner of breaking the circuit when door 28 is opened. The contact- pieces 40 and 33 are norm-ally in electrical contact when door 28 is closed, and also the contact-pieces 42 and 45 are normally in electrical contact when said 4 door is closed. The contact- pieces 40 and 42 are carried by the horizontal arm 44 of the pipe 43. WVhen the door 28 is opened out-' wardly from the cell 26, the arm 44 will pass inwardly in the direction of cell 26, and 'con- 1 sequently contact- pieces 40 and 42 will be removed from contact- pieces 33 and 35 and the circuit broken.

64 and 65 are switches, which are employed for shunting or cutting the circuit out of the doors 27 and 28 when an authorized person 1 desires to open the same, thus preventing an alarm when the doors are opened by an authorized person. The poles of switch 64 are in electrical connection with the contactpieces '38 and 34throughwires 66 and. 67, and

p the poles of switch 65 are in electrical connection with the contactpieces 40 and 42 through wires '68 and 69, and by the proper manipulation or turning of the switch-leverof said switches the current which passes through doors 27 and 28 may be shunted or out out of said doors when an authorized person desires to open the same. The switch-es 64 and 65 are securely contained ina metallic I lock-box 71 and are rendered only accessible to the jai'lo'r or some authorized person.

We prefer to construct the ceiling and floor of the cells or corridors in themanner as illustrated in Fig. 19 and a modification as illustrated in Fig. 1-8, wherein we employ a cover- 5 ing-pla'te 74,provided with a series of depressions or corrugations 75,in which the electric wires are located, and cross each other at the points where the corrugations intersect. Said plate '74 is secured in any suitable and me chanical manner to a smooth plate 7 6, which answers as the fioorof the cell or corridor or may answer as a ceiling.

In Fig. 18 we show a modification wherein we secure a series of. covering-cleats 77, provided with corrugations or crevices 78, to the floor or ceiling of the cell or corridor, and in said crevices or corrugations the electric 1 wires 79 may belocated. By this construction it can be readily perceived that the floor and j ceiling of the cells or corridor are completely protected bya net-work of wires traversing the same.

We desire it understood that whenever we I employ the word pipes in the claims We have reference to all the forms of grate-bars herein described, whether applied to the conf struction shown in Figs. 1 to 16, inclusive, or i to the doors shown in Figs. 21 and 22.
