Dec. 21, 1937. R. TWINDLE SAFETY BAR OR GRATING Filed Feb.v 8, 1957 A. mzagm ffl/fz www Patented Dee. 21, 1937 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to protective bars or gratings and has for the primary object the provision of a device of this character which will be durable, efficient and capable of affording maximum strength and protection and will provide a device that cannot be disassembled or rem'oved by cutting or severing the parts thereof..
With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a front elevation illustrating a protective grating adapted to a window frame of a building and constructed in accordance with my invention. l
Figure 2 is a fragmentary vertical sectional view illustrating thevsame. 1
Figure 3 is a detail sectional view taken on the line 33 of Figure 2.
Referring in detail to the drawing, the numeral I indicates in entirety a protective grating for a window 2 or similar device. The grating I is composed of a plurality'of verticallyand horizontally arranged bars 3r and 4 each composed of a plurality of tubular sections. The sections are joined by couplings 5, said sections being threaded into the couplings. The ends of the horizontally and vertically arranged bars are embedded or otherwise secured in the walls of the building of the window 2. Located in the horizontally and vertically arranged bars are metallic cables 6 each partly constructed of a plurality of twisted metallic strands. The ends of the cables are anchored in the ends of the bars leaving the remaining portions of said cables free of the bars and with a certain amount of slack therein so that should said bars be cut by a hack saw or similar tool, the cables being slack will move within the bars when engaged by the hack saw and consequently render the cutting thereof practically impossible. However, should the hack saw cut a cable to a certain extent, said cable being slack will pinch or grip the hack saw and thereby pre.
Vvent further cutting thereof to bring about complete severance. As long las the cables cannot be severed it is impossible to remove sections of the bars and consequently prevent entrance or exit from the building through the grating.
Bars or gratings of the character described have many uses such as prison cells, safe deposit and bank Vaults, animal cages, doors and windows of buildings which need protection and it is to. be understood that the bars and cables which go to make up the grating can be of any suitable size and also that the bars may be fitted with ornamentation. The ends of thebars when mounted in a building as shown in the oflicial drawing will be sealed to prevent rust and corrosion on the inside. These bars cannot be severed, led or otherwise severed by any tool which depends on friction for its cutting operation.
What is claimed is:
A grating comprising horizontally and ver` tically arranged bars each composed of a plue rality of sections, couplings connecting the sections of the horizontally and vertically arranged bars to each other and of hollow formation, and cables extending through the sections of said bars and the couplings and having the ends thereof secured to the ends of the bars leaving the major portions of said cables unattached from the sections of the bars and couplings for providing suflicient slack in said cables to prevent severance thereof by a tool cutting into sections of the bars and the couplings.
