i Specification of Letters Patent.

Application ledAugust 12, 1907.' Serial No. 388,19).

Patented July 14, 1908.

To all whom'fit may concern:

Be it known that I', EUGENE F. GLocK, a citizen of the United States, residing at Detroit, county of` Wayne, State-of Michigan, have invented a certain new and use ful Improvement Vin Edge-Protectors` for.`

Concrete, anddeclare the following to be a full, clear, and exact description of the same,

. such as will enableothers skilled in the art to 'which 1t pertains to'pmake and use the same,

reference bein had to the accompanying drawings, Whic form a part of thisspecication. This linyention relates to the reinforcement of curbing, and has for its object animproved means` whereby the exposed edge of a concrete or artificial stone curb may be pro`- videdwith a metalfprotector piece, which 4will receiveland resist 'the impact of passing wagon. wheels, or .even the slight, though steady, Wear-'due to the passing of pedestrians. y

.In-the drawings :'-Figure 1, 'is a perspective of ,a section of curbing, the end of the protector piece and of the concrete part being shown in-section. Fig. 2, is a sectional elevation, on an enlarged scale, of themetallic reinforcing piece and a portion of the anchor piece. Fig. 3, is a perspective of the head of an anchor piece. Fig.v 4, is a sectional elevation of a slightly modified form ofY protector piece. Fig. 5, is an elevation of another modified form as respects the engagement ofthe anchor and protector pieces.

A represents the rising portion, and B the gutter portion of a section of concretecurb'- ing, Whose expcsed'upper edge is rounded,

the immediate edge portion being finished by. the curved top -of protector piece C, whose curvature is complementary to the desired contour of the edge as a W ole. l body portion of this protector piece, whose rounded upper surface constitutes this edge,

' extends a neckportion D, which terminates in a claw portion E, which, extending much 4farther .laterally than 'the neck portion D,

servesv in itself asian anchor of considerable holding-,power when embedded inconcrete, which has been allowed vto harden there- In order,- however, to avoid the pos sibility' of an unusual impact tearing the. entire protector piece away from its surrounding concrete, there is provided an' anchor F having-a ilattenedportion G, which, when insertedwithin the claws E of the jprotec- 'tor piece, easily engages therebetween, but

From the which, when turned through ninety degrees, engages with .the edges of'its ilattened ortion G very closely Within the claws E o the protector piece; from its point of engagement at the upper end, it extends downwardly, iirst in an oblique direction, andthen vertically toward the base of the curb, where it again .bends and extends horizontally under the gutter portion. The exact route traversed by the various portions of this anchor piece', with respect to the curb as a whole, is not material or speciiic,lthe idea,

being to aHord, by its'engagement through rthe concrete mass, a sufiicient holding means forl the exposed :protector piece. I

In Fig'. 4- is shown a slightly modified form of the protector piece in which in place of the claws vE, the rear or inner portion of the protector piece is provided with fingers K,"which inclose a space of key-stone form into which a com lementary anchor head M is ada ted to be` tted in manner similar to What as already been described.

In the form illustrated in Fig. 5 the lextreme inner end of .the protectorpiece is. 4solid and unbroken by a trough or keystone shaped. edge, such -as is illustrated in the other figures.. f Instead the neck part D is perforated at suitable intervals with holes through which engages the anchor piece H,

lWhose end J is first inserted when it and the L'An edge protector for a curb, having, in combination with a rounded wearlng sur-- face, a neck portion adapted to extend inwardly into t econcrete, and an anchor portion. of greater dilmreter than the neckportion adapted, by engagement of the concrete thereabout, :to hold the `exposed wearing lsurface 'of the protector in proper position With respect to thecurb, and to be engaged interiorly by detachable anchor piece extending thereto from a remote part of the curb, substantially as described.

2. A-metallic edge protector for a concrete curb and anchorage means therefor, compris'ing a unitary guard piece having a Wearlng surface, an attenuated neek portion and a securing portion at the inner end of said neok portion, and a crooked anchor piece adapted to be inserted in said -securing portion and brought to an interlocking position with. res eot thereto;VA said piece extending from sue point of engagement With the EUGENE F. GLOCK.
