Y inventionv relates toz new Yand useful improvements in the construction o' road t guardsand fences.y

' rails.;

rvl-Ieretorfore roady if'guards ofv the typeA whichthis invention relates have been made generally offV wood construction and 'con-f sist-ed loi' wooden uprights drivenk 'into the Vground atrv regular intervals andvliaving one or morehori'zontally disposed rails extend ngdbetween each pairoir' adjacent uprights andibolted or .nailed thereto. Both the posts andr the rails had to bemade of heavy lumberand had torbe dressedand painted. Asr a large numberof such guards is; used the eX- penses yot construction andmaintenance .is

very great. The uprights andrails have to be painted regularly whichis quite anitem in the cost of maintenance, kand the bolts or nails used to secure the rails to the uprights will rust in the course of time and have ,to be replaced and will also cause decay of the Furthermore, where-such lumber is treated witha preservative, Vit cannot be painted satisfactorily andis unsightly andv not readily visible in the dark.

Thejobjects of the present invention are to provide uprights; of reinforced concrete adapted to beanchored in theVv ground and having their exposed portions provided with suitable recesses into which are adapted to i' belreceiveddand anchoredther'ein the'ends of the horizontally disposed rails.V The, recesses are arranged in pairs, each pair being arranged onI the same-horizontal plane and preferably arranged in communication with each. other whereby the respective ends of .the rails can be interengaged or interloclred lvided with one orpinore pairs of recesses, each pair of recesses being arrangedfon thesame horizontal plane andin dier'entfaces of the upright, aiidlt'orprovided rails having re- Ci'ucingendstting intosaid recesses and `having:said reduced ends provided with suit'- able ,longitudinally` arranged projections whereby tliefadjoiningfends of each pair vof railscan be iiterlocked, thereby holdingsfaid rails against disengagement rrom said up? right. y 'Y j' yStill other objects oit the invention are to provide uprights" of reinforced concrete hav?. ingtheii' upper portions provided with rtwo recesses disposed inthe dit'erent sides of saidl upright and arranged on thesame horizontal planefwith` each other,y and to provide rails of reinforced concrete7 each of said rails havingformed at each. end a reduced extensionV which fits looselywithin the recess of the Lupright', while the' vertical Wall of each end is kiny abutting Contact with the corresponding recessed side Wall'of Vsaid upright, and to provide.,ineansnforanchoringV said reduced exfL tensions with-insaidrecesses.

Vith these and other objects in view, my i l invention consists, in certain novel features cofy of construction and arrangement of parts,

hereinafter more fully described andclainied,Y and illustrated in the` accompanying vdrawkings7 invwhfich Y 2 i Figure lis alfraginental front' elevational viewbf Vafroad guard of my improved construction. f l 1 i Figure 2 isV an enlarged. front elevational view of. one of the uprights, the upper portion thereof being broken away to showfthc eifids of the rails seatedY in? the recesses there- O Y 4 v Figure 3 Ais a vertical crossv sectiontaken transversely vthrough the rails andfshowin` one of the uprightsiinzelevation.

Figure 6 is a similar view showing the other end of said rail.

i Figure 7 is aV horizontal cross section through a corner construct-ion showing the arrangement of recesses and rails.

Referring by numerals to the accompanying drawings, 10 indicates a plurality of uprights formed of reinforced concrete and 11 indicates rails disposed horizontally between each pair of uprights and having their ends seated therein. Each'upright v10 has preferably parallel vertically disposed sides12 and obliquely disposed front and -`rear `sides 14. Each upright is reinforced by a `pair of substantially U-shaped steel barsl. which kare spaced from each other and are embedded in the upright with the ends terminatng in the lower end of the upright and with the curved portionof each reinforcing bar arranged in the upper end of thek upright as shown in Figure 8. Preferably the upper end of the upright is curved to correspond with the disposition of the curved portions of bars 15. The lower portion of each upright is adapted to be anchored in the ground as shown at 16 and in locating the uprights in position lthehole is preferably du larger than the cross sectional area of eac u right so that concrete can be poured in the ole and around said upright, thereby roviding a bed of concrete 17 which securey anchors the upright inV position and increases the weight of the lower end thereof so as to enable it to withstand more successfully impacts delivered thereagainst.

' Eachfside wall 12 ofthe upright is provided with one or morerecesses 18 and the recesses of one side wall are arranged on the same horizontal planes with the recesses on theo positeV side so that the bottom walls 18* o each pair of kcorresponding recesses yis substantially on the same horizontal'plane. The recesses of onev side of each upright are of greater height than the krecesses of theother side, thereby providing clearance openings 18".

The rails or horizontal bars 11 extend between each pair of uprights 10 and each rail isv provided with reduced ends 19, thereby forming shoulders 11a. The reduced ends 19 are inserted into corresponding recesses 18 of the spaced uprights 10. The cross sectional area of each end 19 is considerably less than the cross sectional area of lthe recess 18 so that said ends can be readily intherail The ends of rod 21 extend beyond the reduced ends 19 and one end of said rod is formed to provide a horizontally disposed eye 22 while the other end of the rod is shaped to provide a downwardly presented hook 24. The length of each reduced end 19 is less than the depth of recess 18 and the distance between shoulder portion 11'* and the axis of the eye 22 is equal tothe distance between the shoulder portion 11 and the axis of hook 24. Thus when the reduced ends 19 of the adjoining rails l1 are inserted in the respective recesses, hook 24 of one rail engages the eye 22 of the other rail, thereby tying said rails together. This arrangement unies the structure so that the strain limparted to one of the rails is transmitted not only to the corresponding uprights but also to the adjacent rails and through the latter'to the other uprights. In

this manner a strong yconstruction is provided which will successfully withstand any impact or blows to which the roadguard may be subjected. In the assemblage ofy the rails, the hooks 24 are arranged to occupy recesses "18 which, being of greater height', have suiiicient clearance to permit movement of the hook portions in vertical plane when bringing hooks 24 into engagement with eyes 22;

In the corner construction shown in Figure 7 one set of recesses 18'is arranged 1n the front wall 14a at right angle to therecesses 18 of the side wall 12. Preferably this front wall 14 is formed vertical the same as the side vwall 12 instead of oblique as in the preceding form. The arrangement and method of securing the rails in position is substantially the same' as in the form just described. f As shown in the drawings, rails 19 are used in pairs, the members of each pair being spaced vertically from each other. However, if so desired, only one rail may be used or three or more rails, if necessary. Where the construction is used for fences, the uprights 10 are of the required height and the rails 11 are spaced a suitable distance from each other to receive the fencing.

Asboth the upri hts and the rails-are formed of vreinforce concrete, they can be economically manufactured and can be made of an desired strength and shape. When place in position the metal portions, namely, eyes 22 and hooks 24, are located within recesses 18 and are sealed therein and there is no metal left exposed to the weather.

As my improved roadguard or fence formedr of concrete, it is of strong anddurable construction and the cost and maintenance thereof isreduced to aminimum.

I claim:

1. A roadguard construction comprising in combination, a pair of uprights off reinforced concrete, each of which is provided in its two walls with aligned and communicating recesses, and rails yof reinforced concrete, each of which is provided vat each end with a tenon, one tenon being provided with a metallic eye and the other end with a metallic hook where- Vby the yends of two adjoining rails can be lockedkwith each other within the communieating recesses of said uprights.
