ANCHORAGE FOR CONCRETE WORK.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed July 26, 1910. Serial No. 573,861.

To all whom 'it may concern:

Be it known that I, HARRY L. WEBER, a citizen ofthe United States, residing at Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Anchorages for Concrete Work, of which the following is a specification.

This invention relates to anchorages for reinforced concrete work, generally, and particularly for railroad ties made of Portland cement, sand, gravel, crushed stone, or other suitable aggregate to form a concrete of a suitable nature for the purpose, reinforced with steel or iron rods, or other material commonly employed for reinforcing purposes, and the invention consists of the parts and the constructions, arrangements and combinations of parts which I willv hereinafter describe and claim.

In the accompanying drawings forming a part of this specification, and in which similar reference characters indicate like vparts in the several views. Figure l is a perspective View of a completed railway tie showing the track fastenings and part of the railway rail. Fig. 2 is -a perspective view of a rail plate and anchora e relnoved. Fi o a slightly modified rail ,plate and tieanchor embodying my invention. Fig. 4 is a perspective view of a four-armed anchorage designed for use in sheet concrete roadway construction. Fi 5 is a modificationto be hereinafter re erred to. Fig. 6 is a side elevation of one of the rail clips.

In carrying out my invention I employ for the body of the proposed tie, when the invention is applied thereto, a composition of Portland cement, sand, gravel, crushed stone, or other aggregate suitable to form a concrete which will be satisfactory for the purpose, and I reinforce this concrete so as to make the tie meet the load and shock requirements.

In Figs. 2 and 3, I illustrate a preferred means for the reinforcement of the tieand to these figures I now call special attention. The anchora e shown in Figs. 2 and 3 includes a rai -plate, A, and oppositely eX- tending arms, B, which are cast or dropfor ed in one piece of malleable iron or stee the arms having openings through them to form keys for the plastic concrete and, ifI desired, said arms may be corrugated 3 is a perspective view or otherwise roughened to produce a better lock for the concrete mass; the arms are set vertically on edge and have a depth which somewhat approximates thatl of the completed tie whereby the rail-plate will be exposed on the top surface of the tie and will be in position to receive and secure the track-fastenings.

In the style of anchorage requiring bolts to fasten the rails to the tie, (Fig. 2) I provide the rail-plate with key-hole -shaped openings, A, one or more upon each side of the center of the plate and which openings are designed to receive bolts which are passed first through the round and larger portion of the holes and are thence shoved into the narrower extensions. These bolts pass through suitable rail-clips, D, which have lugs or projections, d, on the undersides adapted to lit into the round part of the bolt-hole, A, in the rail-plate and-thus back up against and hold the securing bolt in proper position, and when the nut, E', of the bolt, E, is tightened up, the rail-clip will hold the bolt in position and the rail to the tie-plate. If desired, a nut-lock, F, of any of the approved forms commonly used `may be employed for locking the bolt after it has been tightened and the rail-clip is properly positioned in engagement with the Hange of the rail, G. The arran ement of the bolt and the rail-clip with its ottom lug' or projection entering the bolt-hole in Athe rail-plate and backing up against the bolt is important, as the bolt is thus secured against rocking or turning during the application of the. securing nut and the attachment of the rail. I

The form of anchorage heretofore described is especially designed for the construction of railroad ties, but it is apparent that the anchorage will be of great benefitin the construction of fence posts, and in all kinds of buildings and in bridge work, Where it becomes necessary to place anchorbolts, drift-pins, spikes, or nails for the purpose of attaching wood or iron to the concrete base.

The anchors will be made of various forms and sizes to suit the nature of the particular work and the changes for these purposes in the form heretofore described will eobvious to those skilled in the art.

In the anchorages designed for a railroad tie, the rail-plate is cast or otherwise made an integral or rigid part of the arms, B, and the size of anchorage used will depend upon the load and shock the parts are to resist. In practice the anchorages for the railroad tie may be about thirty-four inches long and about five inches high; the tieplate which forms the top of the anchorage and which is an integral or rigid portion thereof, may be seven inches Wide, ten inches long and one-half an inch thick, and it will be cast or otherwise provided with the boltholes before mentioned.

If the anchorage is to be used in a railway tie where spikes are to be employed for securing the rail to the rail plate, A', Fig. 5, said anchorage will be provided with a boxlike recess, B', or other suitable holder adapted to securely grip a wooden block, H, driven therein in line with an opening through the top of the rail-plate, as shown in Figs. 3 and 5; this box is corrugated on the inside edges to afford a better grip to the wooden block, which is driven into it, when the rail spikes are driven linto the block. Into the blocks thus positioned the ordinary. or any special form of railroad spike may be driven with its head engaging and holding the rail in proper position to the anchorage.

When the anchorage is used in connection with street, interurban steam, or other industrial railway or tramway, in sheet concrete roadway construction, I employ in addition to the parts heretofore described, the

arms C, which may be substantial counterparts of the arms, B, before mentioned, eX- cept that they are, preferably, formed separate from the rail-plate and the arms, B, and are designed to be arranged at rightangles to the arms, B, to form substantially a cross beneath the rail-plate. To this end, the middle portion of the rail-plate is formed or provided with an opening, a, and the inner ends of the arms, C, are shaped or fashioned with hook-shaped portions, C', with shoulders, C, adapted to abut against the opposite sides of the middle portion of the anchorage formed by the arms, B, as shown in Fig. 4, the inner ends of the arms, C, overlapping and being passed through the opening, a, so that one of the shoulders will abut against one face of the anchorage along one edge of the opening while the other shoulder will abutagainst the opposite face of the anchorage along the opposit-e edge of the opening, the arms, C, being corrugated or otherwise provided with means ,for affording a secure bond for the concrete material.

The anchorages are placed at desirable distances along the line of track, enerally five feet centers, and opposite eac other, and may be connected by means of a reinforcing bar, K, Fig. 4.

It will be understood that when using the construction shown in Fig. 4 and which is especially designed. for use in sheet roadway construction, the rail-plate, A, may be formed with the holes for the bolts as above mentioned, or they may have the inserted wooden blocks, H, for use in connection with spikes, without departing from the spirit of the invention.

It will also be understood that any additional form of reinforcing means in the form of rods, expanded-metal, or like construction may be used in'association with the anchorage without altering the character of the latter, which I regard as the special feature of improvement, but whatever form of reinforcement or arrangement is adopted, it will be with special reference as to size to meet the load requirements, or the requirements of excessive loadings on shock conditions.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
