CONCRETE FENCE CONSTRUCTION.

Specification of Letters latent. Patented A11 10, 1915.

Application filed October 2, 1914. Serial N 0. 864,550.

To all/whom it may concern -Be it known that I, Gnonen AUER, a citizen of the United States, residing at lVhite Plains, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Concrete Fence Construction, of which the following is a specification.

My invention relates to the construction of reinforced concrete fences, serviceable especially as guard rails along country highways and also in other places.

The object is to enable the production of a strong, durable and economical fence from separately formed sections, which are asse mbled in a novel manner, as will hereinafter be more particularly set forth. The fence, while made of previously formed units, is as strong as amonolithic struc ture and possesses special advantages in erection and may also be taken down without substantial injury.

In the accompanying drawingsillustrating two embodiments of the invention: Figure 1 is a side elevation of a portion of a fence embodying my invention; Fig. 2 is a fragmentary sectional elevation showing the meeting ends of two top rail sections tied to the top of one of the posts preparatory to the completion of the joint; Fig. 3 is a similar view showing the-joint completed; Fig. 4.- is a central transverse section through Fig. 3; Fig. 5 is a horizontal section on the line 5-5 of Fig. 4; Fig. 6 is a view similar to Fig. 2, showing another embodiment of the invention; Fig. 7 is a View, partly in. section and partly in elevation,

' showing the joint of Fig. 6 completed; Fig.

8 is a central transverse section through Fig. -7 and Fig. 9 is-a horizontal section on the line 99 of Fig. 8.

The posts 1 are cast separately in suitable molds, either on the job or elsewhere,

' though usually it is more convenient and less expensive tomold them and the other sections at the place where the fence is to be erected. In the sides of the posts as molded are sockets 2, and reinforcing

rods

3 and 4. are embedded in the posts and extend throughout the length thereof. The number and arrangement of these reinforcements maybe varied, but, as shown, there are five, one adjacent each corner and one 1n the middle In accordance with the invention, one or more embedded members project from the top of each post for engagement with e'mbedded members in the top riiil sections. In the particular instance shown, there is one pro ecting member for each post, the same being the middle reinforcement 4, which is extended above the post while the others terminate at or below the upper end thereof; but manifestly the precise details may be varied.

The top rail consists of separately formed

sections

5 or 5 which extend approximately from center to center of the posts, their ends being supported substantially in abuttlng relation on the tops thereof. The said sections, like the posts, are cast in appropriate molds, wherein they are given the ornamental formation shown, or such other shape as may be desired. These sections have' members embedded therein to engage the projecting post members i, in order to tie the rail sections to each other and to the posts; and in both forms-of the invention shown, the engaging portions of the said members, after the parts are in place, are covered by bodies of concrete which is poured in liquid or plastic condition into recesses in the meeting ends of the rail sections, thereby both protecting the metal members and forming a key or additional union between the parts.

Reference will now be made more particu- .rail sections have three or other suitable number of longitudinal reinforcing rods 6 embedded therein at the time the sections are made, the same extending throughout the length of the sections and one or more of them having projecting eyes 7 at their opposite ends. The said rods are preferably slightly oifset at their ends, near the eyes, so that the latter are brought into superposed relation when the sections are assembled'end to end, as will be clear from Fig. 2. The projecting ends of the rods 4: are received within and extend above these eyes, and are threaded as indicated at 8 in order that nuts 9 may be screwed down upon the eyes, in order to increase the strength and security of the constructim.

The rail sections as molded are formed with complementary recesses 10 in their ends, which when the sections are assembled form cavities extending downward from the top of the'rail to the eyes, the said cavities being of suflieient size to accommodate the nuts and a Wrench for applying "the same. After the parts are in position and the nuts 9 have been applied, the cavities are filled with fiuid concrete, which hardens and forms the keys 11.

In the construction shown in Figs. 6 to 9, the top rail sections 5 are provided with three reinforcing rods 6; and, in addition, tie plates or members 12 are embedded 1n the adjacent ends of the sections after the latter are in pliice. To this end the said sections have recesses 10 formed in their ends in the molding operation, these recesses extending from the top downward for. a suitable distance and for a substantial distance lengthwise of the rail sections, so that when the latter are positioned end to end a slotlike cavity is produced at each junction. Below this cavity the end faces are channeled to accommodate the rods 4:. Into the slot-like cavities are placed the plates 12, having openings intermediate their ends through which the said 'rods project, to be engaged by nuts 9 as before. When 'the parts are thus assembled the cavities are filled with fluid concrete forming the bod cs 11, which are finished off to conform to the contour of the rail sections and form an integral union between the same, in addition. to the mechanical connections afforded by the embedded members.

The fence is completed by intermediate rail sections 14, separately molded like the others and containing suitable reinforcing elements. These rail sections are inserted at their ends into the sockets 2 in the posts.

My fence, in contradistinction to most, if not all, prior concrete fences of an integral character, may be readily taken down and put up again. All that is necessary is to break out the cast-i "keys of concrete and disengage the tying means from the projecting post members. The fence is set up again in the manner already described and plastic material again filled into the pockets at the adjoining ends of the top rail sections.

What I claim as new is:

1. A reinforced concrete fence, comprising, reinforced concrete posts, said posts having members embedded therein as formed and projecting at the'tops of the posts, a reinforced concrete top rail formed separately from the posts and in sections. the adjoining ends of which rest on top of the posts. said sections being provided as formed with recesses at their adjoining ends forming pockets open at the top over the posts, means for tying the rail sections to caih other and to the posts, said means ens ae'ing said projecting post members within said pockets, and keys of concrete cast into said pockets and embedding the engaging portions of the tying means and post members. V V

2. A reinforced concrete fence, compris at their adjoining ends forming pockets open at the top over the posts, means for tying the rail sections to each other and to the posts, said means having openings re ceiving the ends of said rods within said pockets, nuts screwed onto the rod ends above the tying means, and concrete cast into said pockets and embedding the rod ,ends with their nuts and the engaging tying means. i

3. A reinforced concrete fence, comprising reinforced concrete posts, said posts having members embedded therein as formed and projecting at the tops of the posts, a reinforced concrete top rail formed separately from the. posts and in sections, the adjoining ends of which rest on top of the posts, said sections being provided as formed with recesses at their adjoining ends forming pockets open at the top over the posts, a tie member in each of said pockets partly within each of the two adjoining ends of rail sections and fastened intermediate its ends to the corresponding projecting post member, and keys of concrete cast into said pockets covering the tie members and post members.

4. In a reinforced concrete fence, reinforced concrete posts having members embedded therein and projecting at the tops of the posts, incombination with a reinforced concrete top rail separately formed and comprising. sections having their adjacent ends supported on top of the posts, keys of concrete cast into recesses in the adjacent ends of the rail sections, and tie plates disposed in these filled recesses and covered by the concrete keys, said plates having openings intermediate their ends engaging the projecting portions of the members embedded in the posts.

5. In a reinforced concrete fence, reinforced ooncrete posts having members embedded therein and projecting at the tops of the posts, in combination with a reinforced concrete top rail separately formed and comprising sections having their adja cent ends supported on top of the posts, keys of concrete cast into recesses in the adjacent ends of the rail sections, tie plates disposed in these filled recesses and covered by the concrete keys, said plates having openings intermediate their ends engaging the projecting portions of the members embedded in the posts, and retaining devices on said post members above said plates and also embedded in said filled recesses.

6. A reinforced concrete fence, comprising relnforcedconcrete posts havlng members embedded therein as formed and prosections being received in said sockets, a reinforced concrete top rail formed separately from the posts and in sections, the adjoining ends of Which rest on top of the posts, said sections being provided as formed with recesses at their adjoining ends forming Copies 0'! this patent may be obtained for five cents eaeh,by addressing the Commissioner of laten ts.
