' Patented July 12, 1938 2,123,417 UNITED STATES PATENT OFFICE 2,123,417 FOOT GUARD John Grier, Fullerton, and Louis J. Hopkins, Wasco, Calif. 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. In using the foot guard, the feet of the oper drawing, the subjoined detailed description, and ator will‘never get inside of the guard plate the appended claims. _ 6 while pipe is being handled. This guard plate In the drawing 30 is of sufficient height that the operator is in Figure 1 is an isometric View of ‘our foot guard stantly aware of the danger to his feet because 30 in position on the‘?oor of the derrick. he would stub his toes against the edge 8.
