Z Claims.

This invention relates to a shield or protector which is shown and described in use for protecting a nre plug, but the invention can be used for other purposes, such as a protector for fire box pedestals, police box pedestals, traffic light standards and the like.

The general object of the invention is to provide a substantially semi-circular shield for partly surrounding the plug to protect the same from damage by being struck by parts of Vehicles or the like, with means whereby the shield v can be easily and quickly swung to one side of the plug when it is desired to attach hose to the plug.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specically pointed out in the appended claims.

in describingY the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a fragmentary top plan` view of portion of a street and sidewalk and of the plug, and showing the invention in position in full lines and in inoperative position by dotted lines.

Figure 2 is an elevation of the plug and the shield, with part of the street in section.

Figure 3 is an elevation of the invention, with parts in section.

Figure 4 is a view of the semi-circular member and its forked stem which is attached to the shield and engages one of the posts.

In this drawing, the letter A indicates a part of a street, the letter B a part of a sidewalk and the letter C a part of a curb. The fire plug is shown at P and in carrying out the invention, I provide a pair of posts I and 2 which have their lower ends embedded in the sidewalk and each post is of tubular construction and is filled with concrete, as shown at 3. The two posts are arranged adjacent the re plug, one at each side thereof, as clearly shown in Figure 1. The` shield 4 is of substantially semi-circular form and is provided with the hand holes or slots 5 in its upper portion and' a substantially semi-circular member 6 is fastened to one of the lower corners of the shield by its forked stem 1 and a relatively short cap 8 is fastened to the upper corner at the same side edge of the shield by a similar forked stem 9. A ring or sleeve I is fastened to the other lower corner of the shield by a forked stem il and a long cap I2 is fastened to the other upper corner of the shield by a forked stern i3. The sleeve or ring I surrounds the post I, while the cap iZ-,fitsover the upper end of said post and when the shield is in closed position, as shown infull lines -in Figure l, the semi-circular member E engages a part of the post 2, while the short cap 8 fits over the upper end of said post. A pin it passes through the post I and acts to limit upward movement of the shield by l0 engagement with the upper end of the ring or sleeve Iii. Thus the shield occupiesthe position shown in Figure 3 in full lines, *whenV the shield is in protective position about the plug, but l when it is desired to swing the shield to inoperative position, as shown in dotted lines in' Figure l, the shield is raised until" the sleeve IB strikes the pin I4, and when this occurs, the cap 8 moves above the post 2, but the cap I2 has its lower portion tting over the post I, so that the ring Ii) and this cap I2 act as a hinge to permit the shield to be swung on the post I to the dotted line position shown in Figure l. Thus the outlets of the iire plug are accessible. Then when it is desired to move the shield back to operative position, it is simply swung on the post I after being lifted to the position shown in dotted lines in Figure 3, until the member 6 strikes the post 2, which will place the cap 8 above the upper end of the post 2 and then by releasing the shield, it 30 will move downwardly under the action of gravityv until the cap 8 engages the upper end of the post 2, which holds the shield in operative position.

As will be seen, this device will prevent vehicles or parts thereof or parts thereon striking the fire plug and injuring the same, even though the vehicles might run over the curb or if a vehicle is being backed into the curb, the shield will prevent the vehicle striking the plug.'

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:

1. A shield for a re plug comprising a pair of posts embedded in the pavement, one on each side of the plug, an arcuate-shaped shield, a sleeve at a lower` corner of the shield for embracing one post, a long cap at the upper corner of said side of the shield for fitting over the top of said post, a short cap at the other upper corner of the shield for tting over the second post, a semi-circular member connected to the other lower corner of the shield for engaging said other post, said shield being adapted to be lifted to free the short cap from its post, whereby the shield can be swung on the rst post.

2. A shield for a fire plug comprising a pair of posts embedded in the pavement, one on each side of the plug, an arcuate-shaped shield, a sleeve at a lower corner of the shield for embracing one post, along cap at the upper corner
