FOOT GUARD

Application June 23, 1936, Serial No. 86,786
6 Claims. (Cl. 211-430)
In the drilling‘ and maintenance of oil wells
or other deep bores, long stands of pipe or tub
ing are racked in a corner of the derrick and
are pushed into position to be racked by a ?oor
man, and when in proper position, the driller
releases a brake which permits the stand of pipe
to drop onto the floor of the derrick. The floor
man frequently places his feet in such a. position
that when the pipe is allowed to drop, it will rest
10 on his feet, causing painful, and sometimes seri
ous injury.
.
An object of our invention is to provide a
simple and inexpensive foot guard which may
be mounted on the floor of the derrick and which
15 is provided with a novel guard plate so arranged
that the feet of the ?oor man cannot be put un
der the pipe or tubing while it is being handled.
Another object is to provide a foot guard of
the character stated, which is adjustable to pro
20
vide for increasingror decreasing stands of pipe
in the derrick.
Still another object is to provide a novel guard
plate on the foot guard which will de?ect the
stand of pipe away from the operator when the
25 pipe is dropped onto the floor of the derrick.
Other objects, advantages and features of in
vention may appear from the accompanying
That is, this rail prevents the ?oor man from‘
pushing the stand of pipe back of the frame 3.
A guard plate 6 extends transversely between
the side members of the frame 3. This guard
plate consists of an inverted V-shaped hood 1, 5
the outer edge of which is curved upwardly, as
shown at 8. The purpose of this curved edge is
to serve as an abutment against which the toes
of the operator will strike if the feet should be
moved too close to the guard plate.
10
The guard plate is reinforced by a tube 9
which is welded or otherwise rigidly secured to
the hood. The tube 9 will prevent the hood from
buckling if weight is placed upon the hood, such
as when the stand of pipe is dropped onto the
hood. The guard plate is adjustable in the frame
by means of two hook pins Hi and H, which pins
are adapted to ?t into any one of the series of
holes l2, 13 in the frame 3. As the size of the
stack of pipe increases, the guard plate can be
moved outwardly by lifting the guard plate up
and dropping the pins Ill and H into the ad
jacent holes in the frame. The pins l0 and H
are preferably welded or otherwise ?xedly at
tached to the peak of the hood 1, as shown at 25
N.
