Specification of Letters Patent.

Application filed October 26, 1912, Serial No. 727,919. Renewed January 15,1916. Serial No. 72,369.

To all whom it may concern:

Be it known that I, WILLIAM E. FICKLEN, a citizen of the United States, residlng 1n the borough of Brooklyn, city of New York,

county and State of New York, have invented certain new and useful Improvements in Edge-Protectors for Artificial Stone, of which the following is a specification.

My invention relates to metal nosings, or edgings, for artificial stone.

More particularly, the invention is adapted as an edging for curbs, gutters and other structures, the edges of which are curved or rounded longitudinally. In curbs and gutthe setting or hardening of thelatter. For

many uses, as for instance when used as a curb or gutter edge, the metal must be of substantial size and strength; and, to have the requisite rigidity and depth of anchorage, is usually provided with a web or rib which lies in a plane transverse to the direction in which the edge extends.

A favorite type of edge protectors has the general shape of a T iron, the cross member of which is the wearing member, and the upright of which is the anchoring member. As shown in the accompanyingdrawings, the wearing member is of heavy bull nose conformation. This form of protector, although admirable so far as its wearing qualities are concerned, is diiiicult to bend to the shape of corners and-other curves. In many instances it is impossible to bend the protector, cold, and at the place of use; and

great delay and expense are involved in ordering especially shaped sections from the shops. Obviously, special shapes cannot be kept in stock in any suflicient amount to meet demands. The difliculty in bending is obviously due to the position of the rigid central web, and to the lines on which it must be bent in following the street corners and curves. Some forms of T bars are provided with large spacious openings or cuts at considerable intervals to serve as elements to interlock the concrete with the protector.

Where such openings or cuts exist, the bar can be bent, but the difficulty of bending the bar to the true curve is nevertheless increased, because the bar will always bend at the weakest point, and so bends out at the cuts or openings. A bar bent in this latter manner is not only humped and unsightly,

but is weak at the curves, where, to receive the impact of heavy trucking and the like,

it should be strongest.

The purpose of the present invention is to render the anchoring web pliable so that it can be shaped to any curve, while cold, and

at the place where it is to be used; without,

however, involving ashortening of the web, or otherwise materially weakening the web, or lessening the depth of anchorage. This purpose is eifected in the present invention by perforating the web with numerous closely arranged small openings, or by I Patented 0ct..1'?, 1916;

closely positioned cuts of various kinds. In

addition to the perforations, it is desirable to turn out or form anchoring tongues or projectors onthe bar. lhe perforations, of course, by reason of the concrete which enters the same, will in themselves, to a greater or less extent, assist in anchoring the bar: and, according to the nature of the conglom crate, should be considered in this connection. The holes or cuts, lying close together, permit bending of the web, both laterally and vertically, so that, at the curves, the distal edges of the web may be crimped, and the web turned slightly from its position of perpendicularity to the wearing nose to allow for the difierence in length of radius of the outer and inner portions of the bar at such points.

An important feature of the invention concerns the manner in which the protector and concrete are bound together. fore, the anchoring of the bar has been eiiected either by'projections from the bar,

Heretoor by holes in the bar, spaced at considerable intervals apart. When such a bar is subjected to heavy blows, it will work loose from the concrete between the points of an chorage, and presently will have a slight play or spring, so that thereafter eachblow on the bar will cause the bar to act as a wedge tending to split the concrete. In many instances the concrete will ultimately split entirely away on one side of the bar. In thepresent invention, however, by reason of the large number of small anchoring points provided by the numerous perform tions or cuts, there can be no starting'point for any looseness of the bar. The bar and concrete are lnterwoven and mterlocked at substantiallyall points of the bar, and destruction of the curb in the manner above of a general T shape,'the wearing nose 1 of NVlllCll is of heavy bull nose and the web 2 of which tapers slightly to its distal edge 3. At close intervals along the web 2, there are tongues or projections at turned out laterally. The cuts 5 which de fine the tongues l aremade at close intervals so as to Weaken the web uniformly throughout the lengthof the same. The tongues, when turned out, provide effective means for anchoring the bar in the concrete. The bar will readily bend in the general direction of the cuts 5', or on a longitudinal line across the upper endsof the cuts. Bending inboth of these directions is wanted if a uniform bend is to be had. 7 In addition to these cuts 5, the web Qhas several vertical and longitudinalrows of perforations 6 formed by punching and bending small pieces 6 out: of the web. By reason of the perforationsb, the web can be readily turned laterally out of its perpendicular position with respect tothe nose 1, on the line of the top row, or of any other row, of holes 6; and can also be bent in a transverse directlon. on the line of any vertical row of the holes 6. In certain instances, either the i I Copies 'ofthis patent maybe obtained for the latter,

cuts. 5alone, or the holes 6 alone, will be sufiicient for the purposes of this invention. Inotherinstan'ces, both may be desirable. Obviously,w h en the bar is placed in the unset concrete, the latter will enter the holesfifand, because: of the number of and also because of the projections 6, the concrete, when it has set, will be 'sointerlocked with the bar as effectively to assist the tongues 4 in anchoring the bar conformation member, and a web, said web having to the concrete throughout the. length of the permit of equal and uniform bending of the same at any point thereof, as and for the purposes described.

An edge protector for concrete curbs, gutters, and the like, having several rows of small holesalong the same, arranged in a series of vertical and horizontal lines for interlockrnent with the concrete, and to permit uniform bending of the same at any point thereof, as and for the purpose de-[ scribed.

8. An edge protector for concrete curbs, gutters, and the like, comprising a wearing extending lengthwise thereof a zone of small holes through the web, which holes are closely stepped both along and across said zone to present a screen-like structure for interweavement of the web with the concrete and to assure flexibility of the web.
