PROTECTING DEVICE FOR CURBS AND THE LIKE.

T allwkom it may concern: v

Be it known that I, WILLIAM E. EI KLEN, a citizen of the United States, residlng at New York city, county of New York, and State of New 'York, have invented certain new and useful Improvements in Protecting Devices for Curbs and the like, of which the following is a specification. My invention relates to improvements in protecting devices or nosings for curbs, gutters, crossing blocks, .expanslon )1IltS 1n concrete roadways, and the llke.

An object of the present inventlon is to provide a nosing or protector, for the purdrawlngs,

poses stated, of such construction as to be anchored at unusual dept-h m-the concrete or artificial conglomerate, forming the curb or block, and in which the anchoring means is integral with the rest of the structure, so as to remain connected therewith, no matter, to what blows or stresses the nosing is subjected under trafiic.

Another object of the invention is to havethe protector of such design as to be capable of cheap construction, and also to be of such design as to be readily and accurately set into the unset concrete or other mastic. A further object of the invention is to provide a nosing or protector which, 1n combination with the features above mentioned,"may be constructed to present a tough, non-slipping surface to trafiic.

Other features of the invention will appear upon reference to the accompanying in which a short length of the protectors is shown in'perspective.

Referring to the drawings, the two wings of the protector or nosing are shown at 1 and 2. Ordinarily the protector is so ositioned in the concrete that wing 1 lies ush with the top surface of the paving block or curb, and wing 2 flush with the vertical face of the block or curb. If the occasion demands, however, the. protector may be so Specification of Letters Patent.

the wings are so out To form the tongues,

before being turned out,

that the tongues, extend lengthwise The tongues may sired length; and v may therefore be secured without necessi: tating any, special attachments to the bar. The cuts are preferably made as near the outer edges of the wings as practicable so that the tongues stamped from one wing may lie at some depth in the concrete below or behind the other wing. The tongues are also preferably shaped to have hooks 5 at their distal ends. Preferably also,'particularly where great depth of anchorage is desired, the tongues are turned to a position at right angles to the wing from which they are formed, and when so positioned, those on one wingare disposed atright angles to those on the other wing. N o matter, therethus .be made of any deor to move it sidewise, there is always one set of tongues which lie practically crosswise to the direction of stress, at some distance from the surface toward which there is a tendency to move the bar, and another set of tongues disposed more nearl in the line of the attempted movement, wlth such deep anchorage as effectively to assist the first set to resist displacement of the bar, and to prevent cracking of the concrete along the plane of the first set. In resisting movements in directions oblique to the surfaces, both sets of tongues have in part the same functions; and this is likewise the case when the bar is so struck or pressed upon as to tend to move it longitudinally. If the tongues are disposed at other than right angles to the wings from which they are formed,.then both sets will always be in part crosswise to any direction of attempted movement; but the same depth of anchorage from the surface will not be obtained unless the tongues are made longer.

In order to avoid slipping of horses, skidding, etc., the bar is so constructed that long continuous metallic surfaces will not be presented at the surface of the pavement when .of the bar or protector.

any depth of anchoragethe bar is used for expansion joints or road crossings. The concrete which fills the openings '6, formed in turning out the tongues, may serve more or less to break the continuity of the metallic surface and to provide a grip for traflic. Unless, however, the tongues are near together, it is adcontinuous non-slipping surface at the top of the bar, by reason of the concrete which fills these openings. The lips 8 serve as additional anchoring means, being particularly useful in resisting longitudinal displacements. The openings 6 and 7 are furthe'rmore important in setting the bar into the concrete. The bar may be positioned in the concrete, either by forcing the bar into the unset concrete, or by holding the bar stationary while the concrete is flooded against it and under-its horizontal wing.

1 It is extremely desirable to have the concrete finally in actual contact with the bar at all points of the inner surface of the wings 1 and 2. The holes 6 and 7 permit the workman to see the level of the concrete below the horizontal wing l, and thus to determine when the concrete properly engages the bar. If the bar and concrete be forced together sufficiently, the concrete will ooze through the openings 6 and '7 and thus automatically indicate the correct setting of the bar. a

The structure shown in the drawings is susceptible of various modifications within the scope of the invention, particularly in respect of the shape and disposition of the anchoring tongues, and surface openings.

What I claim is:

1. An edge protector consisting of a bar which is angle shaped in cross section, thereby comprising two longitudinal sections, said bar having anchor members out from each section, said anchor members being bent away from said sections, the anchor members of one section extending parallel to the surface of the other section.

2. An edge protector comprising a bar which is angle shaped in cross section, whereby said bar is composed .of two longitudinal sections, said sections each having anchor members cut therefrom along lines extending longitudinally of said bar, said members being bent away from said sections, the members of one section extending parallel to the other section. 3. An edge protector comprising a bar which is angle shaped in cross .section, whereby said bar is composed of two longitudinal sections, said sections each having 1 anchor members out therefrom along lines extending longitudinally of said bar, said members being bent away from said sections, the members of one section extending parallel to the other section, said members being hook shaped at their outer ends.

Signed by me at New York city, N. Y., this 31st day of May, 1912.
