JOHN J'. QUINN, OF DENVER, COLORADO.

COMPOSITE RAILWAY-TIE.

Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed January 3, 1911. Serial No. 600,638.

To all whom it may concern:

Be it known that I, JOHN. J. QUINN, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Composite Railway-Ties; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in railway ties in which the body of the tie is composed of cement, concrete or similar or any suitable plastic material.

In connection with the concrete structure I employ steel plates arranged in position for the rails to rest upon to prevent the latter from wearing or crumbling the concrete. Embedded in the body of the tie are metal casings or sockets in which are anchored bolts whose threaded extremities project upwardly, protruding above the tie and constituting locking means for securing plates applied'to the base of the rails.

Having briefly outlined my improved con"- struction, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is lllustrated an embodiment thereof.

In this drawing: Figure 1 is a side elevation of my improved tie showing the track rails applied thereto and illustrated incross section. Fig. 2 is a top plan view of two ties showing the rails applied, one rail being partly broken away at one tie to illustrate the steel plate constituting the seat for the rail. Fig. 3 is a section taken on the line 33, Fig. 2, the parts being shown on a larger scale. Fig. 4 is a cross section of the tie taken on the line 44, Fig. 3, the parts being shown on a still larger scale. Fig. 5 is a similar view showing the locking bolt in a different position. Figs. 6 and 7 are fragmentary sections taken on the lines 6-6 and 77 respectively, of Figs. 4 and 5. Fig. 8 is a perspective view of the locking bolt.. Fig. ,9 is a similar view of one of the keys for securing the locking bolt in position to prevent its withdrawal from the tie. Y

The same reference characters indicate the same parts in all the views. 7 I

Let the numeral 5 designate the body of my improved tie to which is applied two steel plates 6 separated to harmonize with the gage of the track and'forming seats for the rails 7. It is assumed that the body ofthe tie is composed of cement, concrete or similar material which preparatory to molding is in a plastic state. When the tie is molded tubes 8 passed transversely therethrough are molded in the tie in position to form openings for bolts 9 which pass through openings formed in depending flanges 10 of each steel plate 6. This construction makes it practicable to form boltholes in the concrete material for the purpose of securing the steel plates in'place after the tie is molded. On each side of each steel plate, a casing 12 is molded in the tie, these casings being ribbed exteriorly as shown at 13 to prevent them from turning in the concrete. They are also largest at the bottom as'shown at 14 and taper inwardly as they extend upwardly as shown at 15 on two opposite sides, thus securely anchoring the casings in place and preventing the possibility of withdrawing themby an upward movement. These casings on two opposite sides are parallel, being the same width from top to bottom as shown at 16 in Figs. 4 and 5. By virtue of this construction it becomes practicable to form an -elongated opening 17 in each casing 12, the length of the said opening being crosswise of the tie and adapted to receive the elongatedhead 18 of a bolt 19 having a shank 20 whose threaded extremity 21 projects above the tie and passes through an opening 22 formed in a securing plate 23 having a beveled projection 24 adapted to overlap the base 25 of the rail on one side. It will be understood that there are two securing'plates 23, one on each side of the base of the rail, the mechanism for holding the plates in place being of course duplicated and identical on both sides of the rail.

It will be noted that the opening for the head of the bolt is the counterpart of the said head until the bottom of the opening is reached, where the opening is enlarged as shown at 26 to allow the bolt to be given a quarter turn, or from the position shown in Fig. 7 to that illustrated in Fig. 6, thus preventing the withdrawal of the bolt head through the opening by which it entered. Locking keys 27 are then dropped into the opening on opposite sides of the bolt, which prevent its being turned to its original position for withdrawal purposes until the said keys are removed.

Applied to the top of each casing 12 is a plate 28 having an opening of proper size to fit the shank 20 of the bolt. This plate is inserted in a recess formed in the top of the tie for the purpose, and is put in place after the bolt is inserted in the anchor casing. This plate maintains the bolt in a vertical position and prevents any possible rocking movement in the direction of elongation of the opening 17. The plate 28 is provided with short flanges 29 which engage seats 30 surrounding the recess where the body of the plate is located.

After the bolts are inserted and turned to their anchored position, the keys 27 are put in place and the plates 28 applied. The rail-securing plates 23 are then put in place and fastened by nuts 31 applied to the protruding threaded extremities of the bolts. These threaded extremities are equipped with openings 32 beyond the nuts through which cotter pins 33 or other locking keys may be applied to prevent the loosening of the nut. It is evident that locking nuts or any other suitable or equivalent means adapted to accomplish this purpose, may be employed without in any way departing from the spirit of the invention.

In order to facilitate the removal of the keys 27 from the casings 12, each key is provided at its upper extremity with an eye 34 for receiving a hook of any suitable character, whereby the keys may be readily lifted from the casings. When the keys are removed it is evident that the bolt may be given a quarter turn in a direction the reverse of that heretofore explained which will bring its head in line with the opening 17 through which it entered the anchor casing. The bolt may then be withrawn.

From the foregoing description the use of my improved tie will be readily understood. As heretofore intimated, when the tie is molded it contains the casings 12 and the tubes 8 which have open ends flush with the opposite side surfaces of the tie. Each tie is also provided with shallow recesses 4 to receive the top portions of the steel plates 6, while the sides of the tie are also provided with shallow recesses to receive the depending flanges 10 of the steel plates, whereby the outer surfaces of these flanges are flush wit-h the vertical sides of the body of the tie.

Before laying the ties the steel plates should be applied thereto by passing the bolts 9 through the tubes 8 and registering openings formed in the flanges 10. Nuts 3 are then applied to the protruding threaded extremities of these bolts whereby the plates 6 forming the seats for the rails are locked in place.

After the ties are laid the bolts 19 are inserted in the casings 12, their elongated heads being inserted lengthwise of the opening 17, after which the bolt is given a quarter turn for the purpose of locking it in place. The keys 27 are then put in place on opposite sides of the bolt after which the washer plates 28 are applied. The rail-securing plates are then applied to the protruding threaded extremities of the bolts 19 and secured in place by nuts 31 as heretofore explained.

The concrete forming the body of the tie is metal reinforced in any suitable manner. As illustrated rods or bars 35 are' passed longitudinally through the tie for strengthening purposes, though it must be understood that any other suitable metal reinforcement may be employed without in any manner departing from the spirit of the invention.

Having thus described my invention, what I claim is:

1. A tie composed of plastic material, having horizontally disposed tubes molded therein and extending transversely thereof, their extremities being open on opposite sides of the tie, plates forming seats for the rails, and having members depending on opposite sides of the tie, the said depending members having openings registering with the said tubes, bolts passed through the openings of the depending members and said tubes for securing the said seats in place, and means applied to the tie for locking the rails in position on the said plates, substantially as described.

2. The combination of a tie whose body portion is composed of plastic material, casings embedded in the tie and largest at their lower extremities and gradually diminishing in size as they extend'upwardly, the cas ings having elongated openings enlarged at the bottom, bolts adapted to enter the said openings for anchoring purposes, the heads of the bolts being shaped to permit a partial rotation in the enlarged bottom openings, the lower extremities of the openings having stops protruding into the openings and occupying such positions as to be engaged by the elongated heads of the bolts when the latter are turned to a position approximately I track rails in place, substantially as deat right angles to the position at which they scribed. 10 are inserted, pins inserted in the said open- In testimony whereof I afiix my signature ings and engaging the opposite sides of the in presence of two Witnesses.
