SPARKS,
METALLIC GRATI NG FOR JAILS, VAULTS, 8.1.0.
SPECIFICATION forming part of Letters Patent No. 469,520, dated February 23, 1892.
Application filed September '7', 1891. Serial No, 405,021.
To all whom it may concern:
Be it known that I, PERLEY HALE, of the city of Chicago, county of Oool ,and State of Illinois, have invented certain new and use ful Improvements in Metallic Gratings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to improvements in metallic gratings for jails, vaults, and other purposes; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.
In the drawings, Figure l is a perspective view of my complete invention, especially showing the manner of constructing the same. Fig. 2 is a detail View of a portion of one of the lock-bars. Fig. 3 is an enlarged cross section of the key-bar andlock-bar taken through one of the perforations formed in the lock-bar, and Fig. 4 is an enlarged cross-section of the key-bar.
Referring to the drawings, 1 indicates a series of upright vertical bars of any suitable and desired form. Said vertical bars are provided on their upper ends with tenons 2 and on their lower ends with similar tenons. Said tenons 2 are adapted to fit in appropriate perforations formed in the top plate 3, or may also fit in the ceiling of the cell, and the tenons formed on the lower end of said vertical bars may be inserted and secured in suitable chanical manner.
The upright Vertical bars are provided with a series of perforations 5, and projecting from the inner surfaces of said perforations are lugs or tongues 6, substantially of the construction as illustrated in Fig. 1.
Although I have shown only one tongue or lug projecting from the surface of the perfo- (No model.)
rations 5, two or more such lugs or tongues may project therefrom.
The horizontal bars consist of two parts, a lock-bar 7, provided with a series of perforations 8, into which the lugs or tongues 6 may be inserted, and a key-bar 9, provided with a groove throughout its entire length, in which said lock-bar 7 is adapted to snugly fit. The lock-bar 7 is substantially a truncated segment of a circle in cross-section, as illustrated in Fig. 2, and'the key-bar 9 is provided with a longitudinal groove 10 throughout its entire length, which is also substantially a truncated segment of a circuit in cross-section. The lock-bar 7 is adapted to snugly fit in the longitudinal groove 10, as above stated, and is so located therein that its exterior rounded surface is flush with the exterior surface of the key-bar 9, thus presenting a solid bar to the eye. It may be noted in this connection that I can use the vertical bars 1 as horizontal bars, and the lock-bar 7 and key-bar 9 (constituting the aforesaid horizontal bars) as vertical grate-bars. In other words, the vertical bars 1 and the key-bars 9 and the lockbar 7 may be used interchangeably without departing from the nature of my invention.
The terminal ends of the key bars 9 and the lock-bars 7 may be secured in any suitable and mechanical-manner to the adjacent sides of the grating or the walls of the cell, so as to prevent any horizontal movement of the same when in use.
Having fully described my invention, what I claim is- 1. A metallic grating having a series of bars 1, provid edwith perforations, tongues, such as 6, projecting from the surfaces of said perforations, a lock-bar provided with a series of perforations in which said tongues may be inserted, and a key-bar provided with a groove in which said lock-bar is adapted to snugly fit, substantially as set forth.
2. A metallic grating havingas'eries of bars providedwith perforations, tongues projecting from the surfaces of said perforations, a lock-bar, being a truncated segment of a circle in cross-section and provided with a series of perforations in whichsaid tongues may be inserted, and a key-bar provided with a 1011- gitudinal groove, being a truncated segment of a circle in cross-section, in which said lock-- bar is adapted to snugly fit, substantially as set forth.
3. In a metallic grating, a bar provided with perforations having tongues projecting from the surfaces thereof, substantially as set forth.
:1:- In a-metallic grating, a bar provided with circular perforations having tonguesprojecting from the surfaces thereof, substantially as set forth.
5. In a metallic grating, a key-bar provided with a longitudinal groove throughout its entire length, the same being substantially a. truncated segmentof a circle, substantially as set forth.
6. In a metallic grating, a lock-bar provided with a-series of perforations,- the same being substantially a truncated-segmenttof a circle incross-section, substantially as setzforth;
7, A metallic gratingoonsisting-off barsl,
provided Withtenons, 2- and perforations 5,.
I 8. A metallic, grating consisting of bars 1,
providedwith tenons 2 andperforations 5,
