ISRAEL L. LANDIS, OF CHICAGO, ILLINOIS.

STRUCTURE-GUARD.

SPECIFICATION forming part of Letters Patent No. 760,999, dated May 24, .1904.

Application filed November l1, 1902. Renewed November 6, 1903. Serial No. 180,127. (No model.)

To LZ whom it may concern:

Be it known that I, ISRAEL L. LANDIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Structure-Guards, of which the following is a specification.

This invention relates to guards for preventing abrasion from structures built of selfhardening plastic material-such-as cement, so-called artificial stone, and the like-with particular reference to structures exposed to the wear and tear of traiiic, such as streetcurbing.

This invention does not contemplate the broad idea of protecting artificial or natural stone curbing or similar structure with metal shields, which is exceedingly old in the art, nor corner-strips, nor so-called metal clad or bound blocks, the object of the invention being to provide a novel form of preferably metal-protecting plate having substantially integral holding or anchoring means adapted to be built or worked into and upon and form a part of a curb or similar structure while the material is in a plastic state to receive the frictional contact of moving bodies and prevent the abrasion of the most exposed surface or portion of such structure.

The invention consists generally in a curb, the most exposed portion of the vertical edge of which has been faced with a plate having a portion thereof embeddedl in said curb, said embedded portion being provided with suitable anchoring means; and the invention further consists in the various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figures 1, 2, 3, and 4 are vertical sections of curbing blocks provided with different forms of protecting-plates, each embodying my invention. Figs. 5, 6, 7, 8, and 9 are perspective views of the different forms of plates and anchoring means.

Referring now to the drawings in detail,

numeral 2 refers throughout the various views to the protecting face-plate, presenting a Wearing-surface 3 on the vertical edge of the curb structure 6, having a longitudinal portion projecting laterally therefrom throughout its en' tire length designed to be embedded in the curb while the latter is in its plastic state. Suitably disposed on and projecting from the embedded portion 4 are the pins, lugs, or projections 5 5, which provide the anchoring means and which may be separate pins driven therethrough, as shown in Figs. 5, 7, and 8, or integral lugs or projections cut out of and bent away from said embedded portion, as shown in Figs. 6 and 9. Said embedded portion and its anchoring means are designed to be built into the plastic material prior to hardening. Where separate pins are employed to provide the anchoring projections 5 5, they may be of any desired form or length and inserted through the embedded portion 4 after the structure 6 has been partially completed. I prefer, however, to cut and bend outwardly integral portions of the plate 4 to provide the anchoring means, as shown in Figs. 6 and 9.

The peculiar advantages of my invention over other forms of curbing and structure guards lies in the fact that with slight changes common forms of commercial angle-iron and T-bars may be employed, the production of special designs of plates being avoided.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a curbing, the combination, with an artificial-stone curb, of a guard comprising an angle-plate having one wing facing a portion of the vertical edge of said curbing and the other wing being wholly embedded therein, said embedded wing being provided with suitable apertures and separate anchoring means therein, whereby said embedded wing may be fastened to the curbing after the guard has been placed in position.

2. In a curbing, the combination, with an artificial-stone curb, of guard comprising an angle-plate having one wing facing a portion of the outer surface of said curb and the other wing wholly embedded therein, said embedded wing being provided with separate transverse pins whereby said plate may be inter- IOO locked with the curb after the guard has been the guard has been partially embedded in the l O placed in position. structure.

3. In a curbing, the combination, with an In testimony whereof I have hereunto set articial-stone curb, of a guard comprising an my h and in the presence of two Witnesses.

angle-plate having one Wing embedded in the structure and the other wing1 facing its outer ISRAEL L' LANDIS' face, the embedded wing being anchored in Witnesses:

the structure by means of a series of separate J. W. BEGKSTROM,

transverse pins adapted to be inserted after F. E. STEUART.
