MEANS FOR SECURING RAILS TO METAL TIES.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed September 12, 1912. Serial No. 720,031.

To all whom it may concern:

Be it known that I, WILLIAM II. Mon- GAN, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Means for Securing Rails to Metal Ties; and I do hereby 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 appertains to make and use the same.

My invention relates to means for securing rails to metal ties, and is designed as an improvement on the construction disclosed in my Patent 1,028,248 granted to me June 4th, 1912. a

In the patent above referred to thefastener is designed for securing rails to straight ties, and clamping plates are seated on the flanged chair and are provided with lips overlapping the'base flange of the rail, the clamping plates and chair being locked in place by spring clamps bearing against armor plates at the underside of the top flange 01' the tie and against the clamping plates. Vith this patented constructionthe spring clamps are located wholly in planes and the object of this invention is to so construct the parts that the spring clamps will oveizlie or bear directly against the base flange of the rail and be sufficiently close to the latter so as to be protected from the A further object is to dispense altogether with clamping plates and thereby increase the effective hold of the spring clamps.

A further object is to so construct the straight ties, that the chairs used on the bent ties may,without any change, be used on the straight ties, thus dispensing with specially constructed chairs for the straight ties and with the clamping pla s used with With these and other objects in view my invention consists in the parts and combinations of parts, and in the details of construction, as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in section taken lengthwise the rail and at rightangles to the tie. Fig. 2 is a. view in section at right angles'to the rail; Fig. 3 is a view ofa section of the tie hang] ng but with the plate welded thereto; Fig. 4 is avlew of the chair; Fig. 5 a view 01 one of the insulating strips; Figs. 6 and 7 are views similar to Figs. 1 and 2, of a slight-1y modified construction; Figs. 8, 9 and 10 are views the parts shown in Figs. 6 and 7 detached, and Fig. 11 shows the clampv overnot in contact with the base flange of the rail.

In the system of railroad track construc tion, to which this invention is particularly adapted, straight metal ties alternate with Z-shaped ties, the ends of the latter being parallel and constituting supporting members for the rails, and the particular improvement herein disclosed relates solely to the means for securing the rails to the straight ties, the construction being such that the same chairs used on the rail supporting members of the Zshaped ties may also be used in the straight ties, thus simplifying the manufacture and reducing to a considerable extent the cost 01": production.

1 represents a straight metal tie having a top flange 2, and a wider base flange 3, the latter being preferably concaved as shown so as to permit the ballast to pack under the ties, and l is a plate, spot or line welded, or riveted, or otherwise secured to the top flange 2 of the tiev There are two plates to each tie, and each plate carries a chair supporting the rail but as the plates and the manner of securing the rails thereto are alike, a description of one will suflice for both. The plate 4 projects at the front and rear of the tie, as shown in Fig. 1, and the ends thereof are preferably bent upward, so that when the chair 5 is placed thereon its depending flange 6 will terminate above the top of the tie and act as a cushion or yielding support for the rail. The extreme ends of the plate 4 are turned downwardly, as at 8, so as to form end abutments-for the insulated armor plates 9 aga nst which, the lower ends of the spring clamp 10 bear.

The chair 5 is substantially as shown in my Patent 1,026,108, granted May 14th, 1912, and comprises a body having depending flanges 6 and upwardly projecting flanges 7 and 7, atits side edges This chair rests on the plate and extends lengthwise the latter, length of the rail, and the two depending flanges 6 thereof overhang and bear against the side edges of the raised portion of the plate l, and absolutely ,era-l or spreading movement of the chairs,

prevent any lat:

or in, the direction of the v and consequently oi the rails'seated on the chairs. The rail rests on the chair between the upwardly projecting flanges T and 7" thereof, the inner wall of the latter of which is nearer the center ot the chair intermediate the (.lepending flanges, so that by re- Yersing the position of the chair end for in an. upwardly curved tree end. and a lower jaw teru'iinating in an upwart'lly curved free end, the clamps belng'ot a SIZO sutlicientfio rest clear of the plate i and chair.

The upper end of the clamp may bear directly on the rail or it may overlie the base flange ot' the rail without contact ing therewith, while thelow'er end rests in rear of a rib 9 on the arn'ior plate 9, the latter being constructed substantially as shown in the patent above referred to, and resting against the underside of the plate 4 at opposite sides of the tie. ll it be necessary to insulate the rail. from the tie, suit able insulating material 12 is introduced between the armor plate 9 and lower faces of the 'n'ojecting ends of plate at, and-also between plate 4: and chair The clamps 10 above referred to, are preferably made 0tv hard tough and finely grained steel, or alloy of a size sutlicient to hold the rhils to their seats with a yielding pressure. They may be inserted and driven on endwise in the direction of the lengthof the chairs, or they may be sprung on over the side edge of the base flange of the rail.

The construction shown in Figs. 6 and 7 is substantially the same as that; above described except that the plate 4 is flat instead of having upturned ends. with this straight construction, as in Figs. 6 and '7, it is necessary to cut away or recess the depending flanges of the chair as shown in Fig. 9, to receive the top flange of the tie In Figs. 2 and 7 the clamps are shown bearing directly against the top surface of the base flange of the rail. In Fig. 11 the upper jaw of the clamp is shown as overhanging the basefiange of the rail but not; in contact therewith. In this latter construction the clamps bear against the top edges of the flanges 7 and 7 of the chair, leaving a slight clearance between the top of the base flange and the free end of the jaw, so as to permit the rail to have a slightvertical movement; under a rolling load without disturbing the tie in the ballast. With this latter construction the rails are loosely seated on the chairs but as the resultant of the wheel pressure always falls within the' bases of the rails, the only pressure to which a rail is subjected, other than downward, is an outward. one which is taken care of by the side. flanges of the chairs, hence-there is theoretically no tendency for the rails to tip, but as the ends of the clamps overlap the base flanges of the rails, and are onlyreinoved therefrom a limited distance, tipping to anything like a. dangerous extent would be absolutely prevented by the ends of the clamps.

Then the straight ties are used with Z shaped ties as above explained, the plates 4: may be sutliciently long to overlap and rest on the adjacent ends of the Z-shaped ties so that the joint of the rail will be supported by both ties. 7

The chairs and plates can be rolled, thus simplifying the manufacture and reducing the cost of production, and by the use or the plates, the same chair can be used for both the straight and Zshaped tics.

\Vith this constructionthc clamps directly engage. or overhang the rail, instead of a clamping plate, and besides being more etiective, due to leverage, they are located close up to the rail so that they are not liable to lac-dislodged the Wheels or flanges in the event of derailment.

It is evident that many slight changes might be resorted to in the relative arrangenient of parts shown and described without: departing from the spirit and scope of my invention. Hence I' would have it understood that I do not wish to confine myself to the exact construct-ion shown and described, but

I'l'aving fully. described my invention what I claim as new and desire to secure by Letters-Patent, is
