SAFETY CAGE FOR OIL DERRICKS Filed Aug. 12, 1939 Inventor Way/Wiles,
A ttomeys Patented July 1 6, 1940 UNITED STATES PATENT OFFlCE 2,208,194 SAFETY CAGE FOR 011. DERRICKS Application August 12,
2 Claims.
The present invention relates to oil derricks and similar structural devices and has for its primary object to provide a cage which is attachable in a suitable position to the side of the derrick and embodying a platform upon which a workman may stand while disconnecting the pipe or rod, or while performing other work on the derrick.
An important object of the invention isto provide a cage of this character of simple and practical construction, which is strong and durable, which may be easily and quickly attached to a desired position on the derrick and which is otherwise well-adapted for the purposes for which the same is intended.
Further objects and advantages reside in the details of construction as more fully hereinafter described and claimed, reference being hadto the accompanying drawing forming part hereof, wherein like numerals, refer to like parts throughout, and in which- Figure 1 is a top plan View, and
Figure 2 is a sectional view taken substantially on a line 2-2 of Figure 1.
Referring now to the drawing in detail, the numeral 5 designates a pair of angle iron corner posts each having a flange 6 positioned in parallel opposed relation, as shown in Figure 1 of the drawing, and to which is secured the end portion of a U-shaped angle iron platform support I by means of rivets or the like 8. The support 7 includes a horizontal flange 9 and a vertical flange Ill and upon the horizontal flange is positioned a platform l! which is coextensive to flu platform I I is preferably constructed of sheet metal and is provided with drain openings l2.
A plurality of U-shaped rails I3 also have their end portions secured to the flanges 6 of the posts 5, by means of rivets M, or the like, the rails being positioned horizontally and in vertically spaced relation as shown in Figure 2 of the drawing. A pair of vertical brace members l5 are connected at the opposite sides of the rails 13 as well as to the vertical flange ID of the support 7 and a pair of diagonally extending brace rods I6 also extend from the upper rails l3, adjacent its inner end, and extend downwardly and outwardly and are connected to the support 7 at the'bottom of the vertical braces I5.
The posts 5 extend upwardly above the uppermost rail I3 and below the support ,1 and are provided at their upper and lower ends with J bolts I! for clamping to thebeams of the oil derrick or other structure (not shown),
the internal area of the vertical flange Ill. The
1939, Serial No. 289,869 (01. 304-14) From the foregoing it will be apparent that the workmen may stand upon the platform I l and the rails IE will serve as guards to prevent the workmen from falling from the platform.
It is believed the details of construction, utilityv 5 and manner of use of the device will be readily understood from the foregoing without further detailed explanation. Having described the invention what I claim is: i l
l. A safety cage for oil derricks and the like comprising a pair of upstanding angle iron posts, means for securing the posts to the derrick, said posts including flanges positioned in opposed relation and also including flanges extending tol5 ward each other to provide inner corners for the cage, a U-shaped angle iron platform support having its ends secured to said opposed flanges of the posts and extending horizontally therefrom said U -shaped support including a vertical flange and an inwardly extending horizontal flange, a platform supported on the horizontal flange of said support said second-named flanges of the posts and said vertical flange of the support cooperating to keep the platform on the support, a plurality of guard rails secured to said posts and arranged in vertically spaced relation above the platform and brace members connecting said guard rails to the platform support.
2. A safety cage for oil derricks and the like comprising a pair of upstanding angle iron posts, means for securing the posts to the derrick, said posts including flanges positioned in opposed relat-ion and also including flanges extending toward each other to provide inner corners for the cage, a U-shaped angle iron platform support having its ends; secured to said opposed flanges of the posts and extending horizontally therefrom said U-shaped supportincluding a vertical flange and an inwardly extending horizontal ,0 flange, a platform supported on the horizontal flangeof said support said second-named flanges of the posts and said vertical flange of the sup-- port cooperating to keep the platform on the support, a plurality of U-shaped guard rails having their end portions secured to said opposed flanges of the posts and extending horizontally in vertically spaced relation above the platform, vertical brace members connecting the guard rails and the platform support adjacent their outer portions and inclined brace members connecting the uppermost guard rails with said platform support.
