CDCIDDDDDD DDDDDEIIDD ATTORNEY WILLIAM E. FICKLEN, or NEW YORK, N.'Y.

. METAL PROTECTING DEVICE.

Original application led August 21, 1909, Serial No. 513,920. Divided 1912. Serial N0. 699,937.

To all rwhom t may concern.'

Be it known that I, WILLIAM E. FIQKLEN, a citizen of the United States, residing at New York city, county of New York, and

State of New York, have invented certain new and useful Improvements in Metal Frotecting Devices, ofwhich the followlng 1s a specification.

My invention relates to metal protecting devices, for the edges of concrete curbs, gutters, and paving, and for' otherpurposes. The present appllcation is a divislon of my co-pending application Serial #513,920, lcd August 21, 1909. Said application has since matured into my Patent No. 1,098,792, granted to me June 2, 1914. Therem I have obtained claims covering the general construction of a street pavement, roadway or the like consisting of a number of sections with reinforced'upper edges. In this application I seek toprotect the'means by which said reinforcing of the edges of concrete sections making up such a' roadway or street pavement is ei'ected.

One object of my invention is to provide van edge protecting device, simple in construction and easy to set, and one which readily becomes interlocked orl interwoven with the concrete in such a way that while parts of my protecting device enter the mass of concrete, portions of said mass enter openings in the protector whereby the concrete and the protecting bar are doubly 1nterlocked. M bar need not be of heavy material but it s ould be of sufficient thickness and strength to receive and transmit to and distribute among the mass of the curb, road section, or'other object with which it is combined and of which it 'forms a part, the

shocks and jars of vehicular or other trac and pounding.v

It provides a binding for the edges of each unit of pavin or structure whereby said unit may as a wiole expand or contract under climatic changes without affording opportunity for vchecks and cracks to start from the edges exposed and spread through the mass.v Pavements of this type are 4usually laid in large sections.

The Vabove and other objects of them-l vention Willmore fully appear upon refer- 'ence to the accompanying drawings, in

.whichl Figure 1 is a view in cross-.section through a portion of a roadway having a' pavement Specication of Letters'latent.

Patented Sept. 17, 1918.

and this application filed May 27,

equipped with the edge protecting members of the present invention.

Fig. 2 vis a planview of the roadway shown in Fig. 1.

Fig. 3 is a front view of a broken length .of the protecting member.

Fig. 4 is an end view of one of the protecting members.

. Referring to Figs. 3 and 4 the protector is shown as an angle bar, the wings 1, and 2 of which are cut at intervals to permit tongues or lugs 3 and 4 to be turned out of the same. In the form of the invention shown in the drawings, the cuts defining the sides of the tongues are made in planes perpendicular to vthe lengthwise direction of the angle irons; and the cuts defining the distal ends of the tongues are near the bend in the iron. The tongues threfore connect with the wings near the periphery of the latter, permitting the tongues or lugs to be turned to a position remote from the corner, or bend, of the protecting bar, so

as to provide a relatively 'deep anchorage 1n the concrete or other material of which .the pavement or curb is composed. Furthermore, the position of the, tongues is such as not to lnterfere with ready access kof the concrete to the extreme inner corner or bend of the bar when the latter is positioned Looking toward the end of bar (see Fig. 4)

, the tongues 3 and 4 taken together show a 1V 'or wedge shapedV outline, expanding or diverging toward the interior of the curb or paving block, to offer a greater resistance to outward displacement or withdrawal of the bar than would be the case if all the tongues were-turned into the 'same plane.

The holes or openings 5, which are formed when the tongues are turned out, have several important functions. In forcing the. protectors to position in the unset concrete or in flooding the concrete against ythe bar, the holesf' provide view points through the bar so that the level of the concrete below thesame can be observed, and the workman thus enabled to know when the bar has been moved to its proper position, or the concrete properly flooded into place. The holes are really automatic indicators of theA true position of the bar, because the relative position of bar and unset concrete is changed I at these points,

until the latter oozes through the holes and, becomes flush with the outer surface of the protector. The holes also of course provide for the readyescape of the air under protector as the latter is brought t0 osition.

he protrusions of concrete through the holes to the outer surface of the protector offer a close succession of rough surfaces which provide secure footing for horses hoofs and other traffic. This is important, as otherwiseand as actually is the case with certain protectors now in use, the smooth surface of the iron, particularly in Wet Weather, is ineffective to prevent slipping. Again, the interlocking of the concrete with the protector, by reason of the holes in the latter, provides an anchorage which supplements the anchorage afforded by the members 3 and 4, and which is particularly effective in assisting t0 resist ongitudinal displacement of the bar, and this is true Where the concrete is exposed Within the expansion joint through t e openings in the wing 2.

In Figs. 1 and 2 the protector is shown as applied in pairs to the opposing corners of the pavement blocks and 7 at the expansion joints 8. The openings 5 in the protector, with the concrete therein, are also distinctly shown in Fig. 2. In Figs. 1 and 2 the protector is also shown as applied to the edge or corner of a sidewalk member` 10 v to serve as a curb nosing.

The application of ter edges, crossing, and building'. blocks, etc., will be readily understood. When the lprotector is in place, and the concrete has set, the tongues from oney wing, by extending toward those of the other -Wing, together form almost continuous bars behind the concrete Within the angle iron, thus efe fect'ively locking the protector against displacement.

The structure shown in the drawings can obviously be modified to a considerable degrec,v Within the scope of the invention. rlhe bar can also be placed so that one Wing, only, lies at the surface ofv the protected structure; the other vWing being directed into the structure.

What I claim is:

1. An edge protecting bar for the edges of sections of hydraulic concrete sheet pavements when said pavements are made in large sections, which protector consists of a metal strip adapted to be set iush with a face of a section, said strip provided with tongues cut therefrom and bent away therefrom on one side, thus providing anchoring means extendin away from one face only of said strip an leaving openings into Which concrete may fiow, interweaving and interlocking of the concrete and strip being thus effected.

the invention to gut-- museo 2. A sheet concrete road or pavement reinforcing stripor bar provided with arts sheared therefrom and bent a'Way tlierefrom in the direction of the concrete and forming anchoring tongues and supporting shelves, the strip itself forming substan tially a faceplate adapted to remain at the face or surface of the concrete and not itself substantially to enter the concrete 4. An edge protector for concrete pave-` ments or the like consisting of a metal angle bar, or strip havin anchoring projections formed from the odies of the Wing,

at a point close tothe apex of the angle,

the projections ,A extending substantially at right angles to the wing from which theyA are formed, and adjacent projections being bent slightly to either side of the perpen dicular of the bar, the extremities of the projections from one side of the bar being in proximity to the extremities of the projections from the other side of the bar.

5. A corner protector of angular cross section for the edges of concrete provided with wiiig members, Vthe upper member of which is provided with a series of spaced openings to receive and expose the concrete 'v and thus-provide anti-slipping surfaces, and also with means cut out and bent back from A -said opening for anchoring the protector to the concrete. y

6. In a concrete paving surface, a pair of metal protecting members each set flush with a face of and interlocked or interwoven with concrete material on each side of a joint in said concrete paving surface, each of said dy of the Wing atv members being provided` with anchoring elements partly cut out of said members and bent to enter the concrete therefrom, thus making recesses into which concrete passes.

7. A corner protector of angular cross section for edges of concrete having wing members, a member of which is provided with vpartially cut out sections bent from the plane of said member to form anchoring projections, openings being thus provided to re ceive and expose the concrete, for the pur-` pose of providing anti-slipping surfaces.

8. A corner protector of angular cross section for the edges of concrete having wing members, one of which is provided with pairs of partially cut out sections, each of which is bent to lie in a Adifferent plane from the other, and from the plane of the member from which they are cut, to form anchoring projections to secure theprotector to the concrete.

9. An edge protector for concrete pave? ments and the like, consisting of a metal bar or strip having anchoring tongues or projections cut out therefrom at intervals therealong, thus providing surrounding openings therethrough t0 receive and expose the concrete to assist in anchoring the strip to the concrete, and provide anti-slipping surfaces.

l0. An edge protector for concrete pavements and the like consisting of a metal bar or strip having tongues or projections cut out therefrom at intervals therealong thus providing surrounding openings therein, the tongues to project into the body of the concrete, and openings to receive and 'expose thev concrete, to anchor and secure the strip tothe concrete, and provide anti-slipping surfaces.

11. In a concrete paving element and combination with the pavement, a metal protecting strip set flush with a face of Said element, and embedded in the material of said element, said strip being provided with tongues sheared therefrom and bent away therefrom to enter the concrete and to provide openings into which the concrete enters whereby a double interlocking or inter- Weaving bondis formed between the concrete and the strip.

12. In a concrete paving element and in combination with the pavement, a metal protecting member or strip set flush with a face or projections cut out from the flush set portion or portions thereof at intervals therealong, thus providing surrounded openings therein, the tongues to project into the body of the concrete, and the openings to receive theconcrete, to anchor and secure the strip to the concrete.

14. A pavement edge reinforcing means adapted to form an integral part of a concrete pavement section, comprising an extended strip or web of metal and cut out of and bent back inthe direction of the concrete pavement section thereby forming elongated tongues, said 'tongues being cut wholly out of said strip or web so as to leave inclosed openings into and through which concrete may pass while iiuid whereby through the agency of said tongues the con- L crete and the protecting bar are mutually interlocked or interwoven into one.
