I Application filed June 3,

My invention relates ventingthe driving of roads from the time BARRICADE.

to barricades forpie vehicles over concrete the Concrete is placed until it has become sufficiently set to be prop- 5 erly used for trailic for all kinds. of vehicles, or for the purpose of preventing trafiic over any section of a concrete road for any purpose whatever.

In the construction of ordinary concrete roads, a considerable number of days must elapse from the time the concrete is placed in a plastic condition its full strength,

until it has acquired during which period the 7 surface of the concrete must be kept moist or otherwise treated, and the concrete must be protected against feet per day, eight (28) days must the concrete is placed undue strains. roads are laid at the rate of several hundred and fourteen (14) to twenty Since elapse from the time until itvis ready for service, a very considerable length of road may have been completed, but not be suitable for trafiic. Unde there is a strong temp r these circumstances tation for parties desiring to use the road to drive over it before the necessary time has elapsed. To prevent this, the proper authorities post signs forbidding such trespass, cades or obstructions and also place barrito prevent access-to the road. In the past the barricades have usually been .of such a so easy to remove,

temporary nature, or

that parties desiring to use the road have either demolished them or moved them to one side and left the road unobstructed. Furthermore, the usual barricade involves considerable labor in digging holes and in erection, and W the erection of for temporary posts hen it is necessary to move the barricade ahead to opento traffic a section of properly materials in the old b value. Some types of cables, are a menace aged pavement, the arricade are of little barricade, such as wire due to low visibility,

and great power for destruction in case of accidental collision.

The purpose of this 'inventionis to provide a barricade that can not readily be removed by authority, a barricade in place; also to const such a waythat it is a person without the necessary which may be locked ruct'the barricade in sufficiently strong to resist ordinary attempts to remove it without destroying it,

V i 1 V f As shown in Fig. 1 and Fig. 2, 'A is'the barricade proper, road. B is a support at one end, and C. a support at thev other end thereof. These of structural, steel or other The central. portion A, in the preferred form as shown, consists of top angle 1, ,andbottom. angle 2, with lattice Work 3 between these angles, and up-' which Fig. 1 is an elevation looking along which stretches across the I at 6 and 7 upon the finished concrete. road slab D, which slab is not a partofthis invention.

v The support on end portion consists of upright angles 8, with their bottoms bent to form a hook 9, rigidly'secured toa horizontal member 10 in such a manner that the disbottom of member 10 is a little greater than the thickness of the concrete pavement which this support is to'engage. Secured between theangles 8 are'tlie lugs 11 and12, which have downwardly extending ends 13 and 14that pass'through the holes in eyebars 15 and 16 in members '1 and 2.

The other end portion, port C is similar to support B-excepting that v 17 pivoted to C at 18, and that at top of support-C the standard or I sup-- tance between the .face of hook 9 and the downwardly extending plate 19 attached to member 1 may pass between the angles forming C. A padlock 20 is provided to fit in any of a number of holes 21 in plate 19. The manner of'assembling is as follows: The gate A is held in ing upon the pavement with member ,4; close to one edge thereof. The member B is then attached to A by slipping the lugs 13 and 14 through. the holes in eyebars 15 and 16.at tached to the members 1 and 2. The whole structure is then pushed toward the pavement so that the pavement edge is engaged between hook 9 and the horizontal member 10. One side of the barricade is then supported and held erect by engaging the concrete slab.

crejte pavement.

IWith the barricade erected and locked by the padlock it is impossible for anybody to remove the barricade withoutfirst removing the lock or damaging the barricade by bending some parts of it, but it is very easy for a person with proper authority to remove the barricade and to set it up in a new position It is also comparatively easy to open the barricade removing support C and swinging the gate A for the passage of authorized traffic. The barricade is readily visible, and incase of accidental collison,

the lugs and eyebars will presumably bend and release the gate A tendmg to reduce the "damage. .The erection of the barricade is simplified by the custom of leaving the edges of the pavement exposed by the removal of the forms for the pavement. 'The balance of the highway right of way may be closed by extending chains from the ends of member 1 to the adjacent right of .way fence, if any. Thus little or no digging is required. Ofiicial notices forbidding trespass upon the barricaded section may readily "be attached to the gate A.

In other forms of my invention, the gate v.A may be dispensed with and the supports 13 and C braced against the pavement and connected by a chain lying upon the pavement to prevent movement transverse to the pavement, and closure may be efiected by a chain between the .tops of the two supports.
