useful Corner-Guard for Concrete Curbing and the like, of which the following is a specification.

My present invention consists of a novel construction of a corner guard for concrete curbing and the like which is provided with a novel anchoring and alining device, whereby the edge of the completed structure is protected and its liability to injury from vehicles and other causes practically eliminated.

My novel invention is capable of installation without the employment of skilled labor, and since the concrete is positively reinforced and the guard expands and contracts uniformly with the concrete in which it is embedded, it is not affected by frost or other climatic conditions.

My invention further consists of a novel construction of an anchoring and alining device, by the employment of which the corner guard'may be readily alined'with respect to the work and which may be readily interlocked with the curb guard.

lVith the above and other objects in view which will hereinafter more clearly appear in the detailed description, my invention consists of a novel construction of a corner guard, in conjunction with which is em ployed a novel construction of an anchoring and alining device adapted to resiliently interlock therewith and provide means to position, aline, and anchor the curb guard.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings forms thereof which are at present preferred by me, since the same, have been found in practice to give satisfactory and reliable results, although it isto be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective View of the alining and anchoring device in .de-

tached position. Fig. 2 represents an endelevation of a curb guard. Fig. 3 represents a sectional elevation, showing the po-- sition the parts assume at one stage of the construction. Fig. irepresents in perspective, a sectional view of the completed work. Fig. 5 represents a perspective view .of another embodiment of my invention.

. Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates a curb guard which. comprises a body portion 2, the outer face 3 of which is prefer ably convex and terminates at the upper portion in a depending, overhanging, or substantially vertical flange 4 and at its lower end terminates in substantially a horizontal or laterally extending flange 5, whereby the walls or seats 6 and 7 are formed. The inner face of the guard is preferably curved, as indicated at 8. It will be seen that in the preferred embodiment of curb guard, as illustrated, an upper outer face 9 is shown which is substantially flat, and an outer lower face 10 is shown, which is also substantially flat. 1

.11 designates my novel anchoring and alining element, preferably metal, .and which preferably consists of an integral piece of material andcomprises a body portion 12, which latter is preferably substanthe walls of which are formed insuch a manner as to receive the laterally extending terminal 5 of the curb guard 1. The forward edge of the body portion 12 above-the recess 141 is shaped as at 15 to conform to'the inner face 8 of the curb guard '1 and is provided with a laterally extending tongue 16 which, when the parts are assembled, is in close engagement with the inner face 8 of the curb guardl.

17 designates a slot, which in the present instance, projects downwardly and rearwardly from the forward end of the body 12, and a portion of the material removed to form the slot is deflected laterally to form an anchor element 18. This anchoring element 18 is deflected in any desired manner. The forward end of the slot 17 preferably projectsupwardly, as indicated at 19, at an angle. to the remaining portion of such slot.

This slot 17 forms a resilient or spring element or arm 20, the forward end of which is -laterally deflected to form a tongue 21,

adapted to closely engage the inner face 8 of the curb guard 1. The upper face of the arm 20 is inclined, as at 22, in order that the same will interlock with the inner wall 7 of the upper' terminal 4 of the curb guard 1. The upper face or edge 23 of the anchor 11 extends rearwardly and downwardly while the lower face or edge 24 is substantially horizontal. The rear end 25 of the body 12 is preferably perpendicular.

In the embodiment seen in Fig. 5, the construction is substantially the same as that in Fig. 1, except that the end of the arm '20 is split to form extensions and 31, which are directed in opposite directions and the forward portion of the body 12 is split to form two oppositely directed lateral extensions 32 and 33.

In the installation of my novel invention it will be understood that the work is built up, as indicated at 26, and a front board or mold 27 and a rear board or mold 28 are placed in position. The anchoring element 12 is interlocked with the curb guard so that as soon as the body 12 is placed in position, the curb guard is accurately positioned and alined with respect to the construction and extends substantially throughout the width of the curb and maintains the curb guard in position during the process of construction. The portion 29 of the concrete is then placed in position so as to embed the anchoring and alining device 11 and the anchor 18 thereof, it being understood that the concrete fills in the slot 17 so that as soon as the concrete is set and the front and rear mold boards 27 and 28 respectively are removed, the corresponding parts appear, as seen in Fig. 4,

and the corner guards and anchoring devices are interlocked in such a manner as to positively secure the corner guard in position. After the rear board 28 is removed, the con .struction in rear of the anchoring and alining devices 11 is completed in the usual manner. IVhen the work is completed, the wall 13 of the anchoring device 11 and the wall 10-of the curb guard may, if desired, be in substantial alinement and the upper face or wall 9 of the curb guard is in alinement with the upper surface of the completed construction. It will thus be apparent that when the construction is completed, the anchoring device is firmly secured in the body of the construction, from which it cannot be dislodged by blows, frost, expansion or contraction or any other causes tending to dislodge or destroy corner guards as ordinarily employed.

In my present invention, I have entirely dispensed with the necessity of employing separate retaining and alining devices for the curb guard, so that the construction may be completed with economy and rapidity and with consequent decrease in the cost of installation as it is unnecessary to employ skilled labor.

Owing to the provision of the spring arm 20, the anchoring and alining device can be readily interlocked with the curb guard and will spring into such position that accidental displacement of the different parts is positively prevented. It will be seen that the anchoring device is interlocked. with the in turned longitudinal flanges of the corner guard, and that such corner guard is also interlocked with the concrete, which latter positively prevents the unlocking of the anchoring device with the corner guard.

It will now be apparent that I have devised a novel and useful construction of a corner guard for concrete curbing and the like, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is

1. In a device of the character stated, a corner guard, comprising a strip having top and side portions, each provided with an inturned longitudinal flange on each of its longitudinal edges and adapted to form a locking engagement with the concrete, and an anchoring device having means at one end to resiliently interlock with said flanges, said anch oring devices extending substantially throughout the width of the curb and maintaining said strip in position during the process of construction.
