.Application tiled November 5, 1917. 'Serial No. 209,804.

To all wlio'm 'it may concern.' A

Be it known that I, WILLIAM S. GonwIN, a citizen ofthe United States, residing at Baltimore, State of Maryland, .have invented certain new and useful Improvements Vin Paving-Guards, ot' .which the following is a specification.

. This invention relates to improvements in roadways generally, and more particularly to c paving guard for roadways having asphaltie surfaces.

While, as above stated, the invention rc- .lates particularly to a paving guard for roadways, the roadway is, to some extent, in-

accordance with my invention, so constructed as to coperate with the guard in accomplishing the purposes of thc invention.

ln roadways of thisl character, especially those very 'generally and extensively eolistructcd insnburban and rural districts, in which there is a base of vconcrete,macadam or gravel,` and a bituminous surface, or surtace of bricks or blocks, the roadway is made l or paved to loose stone shoulders, or to plankingor they concrete base' ou the sides is extended up to the surface level of the' roadway, forming, with the latter iiiethod. a smooth concrete edge. These sidin, i;;-` or edges, having for their purpose to limit or define' the width of the roadway,` have Y proven very unsatisfactory, as t-he traiiic -soon wears away the edges ofithe roadway and there being no support for the paving it disintegrates.u becomes ragged, and merges into the locust` dirt ofthe side of the road, resulting in the destruction of the road on the sides andl requiring constant and expensive repairs.

The. object ofthis invention is to overcome those objections, which I do by providing a. metallic yguard generally inthe form of an angle-iron. extending longitudii'ially along the roadway 'for thc entire distance or length thereof. the. guard beine anchored :it suitable intervals in the base of the roadway, which, according to the character of the roadbase, may be' of concrete., broken stones or gravel, as to form the necessary bed to retain thc anchor, and thereby the guard. and to support the surface of the roadway adjacent to ,the edges, whether said surface bc of the monolithic type, such as a bituminous layer, or blocks or bricks.

A further object of the invention is to provide a thoroughly practical. durable and eeonomieal constructionv--partienlarlyA eee- I of concrete.

noinieal when the -sa-vin in the expensoinci dent to repairs is consi( ered.

A still further objectis to provide, in'

cases` where the guard is employed in connection with a roadway havin a. surface of bricks or blocks, i1 means or permitting slight lateral expansion of the roadbed,

as will appear from theillustrations and the description. v

In the 4drawings, c

Figure 1 is a sections` of a 4portion of a.

A roadbed,sliowing the road constructed with a macadam base, and a bituminous surface. "Fig. 2 is a similar view showing the guard used in connection with a roadway having :i bituminous siii-face, and base Vof macadam :ind concrete.

Fig; 3 is a similar view showing a section of a roadwav in which the base is entirely Fig. 4 is a sii-iiilaiview of a portion of a roadway, in which the surface is formed of 'i blocks or bricks. y

Fig. 5 is a perspective view of a section of the preferred form of guard, showing the manner of cutting the same out to form the anchor Fig. (i is a transverse section of-,the guard taken about on line .vf-.ii of Fig. 5 showing the manner of bending down the cnt sectioii to form the anchor. Fig. 7 isa modification of the gua-rd show.- ing theanchor made in la separate piece, and attached to the'guard proper.

- Fig. 8 vis a top plan view 'of still another modification of the guard made in serpentine form and riveted to the guard, proper at intervals in .its` onvolutions.A

I have only illustrated a section of roadwa y. where the'surface is of'. blocks or bricks,

.in which the base is of macadam, -or may beA of gravel. but it will be understood that. in constructing a roadwav of this type, the en-` tire base may be' of concrete. like that showirA 100 in Fig. 4.

Referring to the drawings, the numeral l ably below the base at ne bottom, as indicated at 3. This-concrete also extends somewhat beyond the roadwayproper as indicated at Li, thus forming a substantial lfoun- 5 dationfor the metallic guard 5,which iis formed of angle irons of appropriate and eonvenientlen'gtli, arranged end toend and extending longitudinally along the roadway, there being a guard iorined'f such sections v on each side of the road. The angle-irons are" forriicd ivitli a. irrt-icaliiange 6 and horizontaliiange tho'fveiticaliiiang'e being ofA suitable depth loif retaining the surface of `th a' d`\\"a1\'.,.andthe horizontal flange being cida..depthisitableffor providing the anchors at'fiiiter'val throughout. the guard sections. The numeraltl-designates `a bituminous or .isphulticsurface 4'of the roadway of the 'monolithic type, the base olffoimdation for which being,l formed of unacadani. The l)ituiiiiniisfIsilraee is lilled in `flush with tliduppeii edgdfftlid vertical part of the .-griartLas.shoii'il. l

- Iii-the tj-'p'e rinidway illustrated i\i l*`ig {thenpieral'l designates paving blocks of any's'liitable characte When these are used upon; thebases illustrated, eitherentirely of concrete orf'grayel, or oigravel alone, there is filled inrupon the base, a stratum or layer of sand lita and in this. the blocks arc-eniv bedded. 'In'.this forni,.i t will benoted, the vertical portion of the guard isconsiderably longer than the lhorizontal portion, to accommodate the depth or thicknesses of theA blocks, and' interposed between the outer I,series of blocks'and the inner faces of the.

guard, is a plate of bituminous material such as asphalt or tar, or other compressible material 11, to permit of. lateral expansion and 10 contraction of the surface.

The form of guard I prefer-is illustrated in Fig. 5 in ,which the material of the horizontal flange is cut out .at intervals,l as indicated at 12, and bent first downwardly at' 4.5 right angles to the flange, and then laterally Ato orm anchors 13the lower vends of the anchors being sharply bent to form angle pieces 14, for the purpose of getting a better hold or lock' in the base for the purpose .of

anchoring the guards .firmly in place." This :is probably the most economical'way to forinthis form bgi.; like thi` anchor first de ibed, bent' sharply at its lower end, as inmated ame, for beu-e1- hoid in the base.

v455 themodiicationsliown in Fig. 8, the

ationA vin Fig. 7, the anchors'may `road as made entirely of concrete, butI desire it understood that my invention does not reside in the fact of continuing the con' crete base entirelyacross the roadway, it be ing only essential to my purposes, in whatever type of roadway I may construct, that the base beef a character lo firmly retain the anchors, and thereby the guards. Having thus described my invention, what I claim 1. A. metallic guard for defining the lon`r gitudinal edges of' roadways, said guard having an upwardly extending portion,

forming a` boundary for the upper edges of 'the roadway, said guard having also a.-lat

erally extending integral flange remote from -its upper edge and eut longitudinally :1t-.inl- .tervals, the cut portions being bent downwardly und outwardly to forni anchorsfsaid anchors attheir lower ends' being bent ap? roximately at right angles, said anchors lng adapted to hold'the guards in place.

2. In a roadway', in combination, a inetal lic guard having an upwardly vextending .portion extendingtothe surface ofthe roadway and frmin la boundary for the su1'' i face, said guard laying also u llaterally ex tending integral flange remote from its upper edge and cut longitudinally at intervals,

the cut portions being bent to form `anchors for holding the guards in place. i'

'4. A metallic guard for' defining the longitudinal edges of roadways, said guard hat.;
