IlhOCK-ITUI. .ATTACHMENTY FOR RAILROAD-CHAIRS.

The Schedule referred to in these-Letters Patent and making part of the same.

To all whom t't may concern:

Be it known that I, G. W. R. BAYLEY, of Algiers,

vin the parish of Orleans, and State of Louisiana, have Y reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I willl proceed to describe it.

My invention relates to the fastening of railway-rail joints, where ishingbars.and screw-bolts are used to connect the ends ofthe rails, or to the fastening to gether the parts of compound rails, by means of screwbolts; and consists in certain modifications and additions to the plan patented to me, December 29,1868,

in which I employ a novel method of constructing and` proportioning the rail-joint or intermediate chair in relation to the nuts ofthe rail-joint or intermediate screwbolts, in such a manner as to lock the nuts securely in place, and prevent them from turning or working loose, as hereinafter more fully explained.

' In the drawings- Figures 1, 2, 3, 4, and 5, are side or plan views o f rail-joints, and different forms of the chair for looking the nuts.

Figure 6 is a cross-vertical section, on the line :v-x of iig. 2.

Figures 7, 8, 9, and 10, are views of certain modi'- cations of the lips of the chair for locking the nuts.

As is well known, iu the construction of railroads, it is a common practice to unite the adjoining ends of the rails by means of fishing-bars and screw-bolts. The shing-bars consist of a pair of short iron bars or plates,

.made to iit, one on each side of-the rails, between the head andV base of the same, so as to lap over each way past the-joint or point of contact of the ends oftwo rails,

' where they are secured to the same by screw-bolts,

which pass through them and the ends of the rail. The heads of these bolts on the one side, and the nuts on the other, when screwed up, clamp the bars rmly to the rails, and cause them to preserve that continuity of line and 4surface at the joint which is essential to smoothness of track. j

In the case of compound rails, the two or more parts composingit may be bound together, byA screw-bolts, at intermediate points, without the use of iishing-bars, and with but a single one at the half joints. 1

In practice, it has been found impossible to keep the nuts of railway-rail bolts from working loose or entirely off. As the continuity of the line of rail, as well as the intermediate fastening, depends upon these nutsV keeping their proper position, constant attention and labor are required to detect them when loose, and screw them up again, but under this operation they soon become so worn as to be useless, as well as the bolts themselves, from the wearing out of the screw-threads.

To remedy this ditculty, various deviceshave been invented for the purpose of locking the nuts, but heretofore these devices have consisted principally in the use of-supplemental pieces as wedges, pins, keys, washers, Ste., or in new andunusnal forms of bolts or nuts, or of double or jam-nuts. Many of these devices are entirely useless for the purpose designed, and others are expensive, difcultof construction, application, or maintenance, or are otherwise objectionable.

My invention has for its object the accomplishment v ofthe end desired, to wit, the perfect, secure, reliable, and permanent locking of railroad-rail-bolt nuts, without the use of any unusual or complicated parts or pieces, and without requiring any change in the forms or dimensions usually given to bolts and nuts. Being simple in construction, it can readily be applied to any fished joints, old or new.

To accomplish this locking of the nuts, as described,

I construct a railroad-chair, (i, having a lip, a, formed on it in some one', substantially, of the shapes shown in the dii'erent ligures in the drawings.

This lip a, I construct of different shapes, sizes,

lengths, heights, Sto., as is clearly shown in the drawings, so that when the screw-bolts c are inserted through the shing-bars B and the rails A, and the nuts D are placed theron and screwed up, so as to bring their sides into proper position, the corresponding sides or edges of the lip a shall abut against or iit near to one or more of the sides of the nut D, whether the same are horizontal, inclined, or vertical, and thus securely lock them, so as to prevent their turning, as clearly shownin gs. l, 2, 34, 5, 6, 8, 9, and 10.

This lip a of the chair C may also be so constructed as to have holes or openings in them, in shape corresponding to the shape of the nut D, whatever that may be, as shown in iig. 1.

The object, it will be seen, is in all cases to lock the nut of the bolt by means of the lip of the chair, by bringing the lip in contact with the nut in any manner that will secure this result.

In a similar manner, the nuts of rail-bolts used for confining or binding` .together the parts of a compound rail, either with or without a {ish-bar pr ishing-bars, can be locked sccu'rely in place.

It is obvious that the form, position, and dimensions of the lip or lips a of the chair '0, whether` made of cast, wrought, rolled, or plate-iron, or other suitable metal, must be such as to iit or correspond to one or more of the sides of the nut or nuts to belocked.

The forms and dimensions of the nuts used may or may not be diffcrentfrom those in common use. They may have four or more sides, or be elliptical in shape,

and, with their bolts, be placed in any desired position.

One or more bolts, as desired, may be used at the joints of the rails, or at intermediate points. The nut or nuts'of the bolt or bolts can be readily and securely locked by the lip or lips of the chair, as described.

In applying my invention, the screw-bolts c are first inserted through the fishing-bars B and rails A, and

f `the nuts D placed thereon and screwed up. Then the chair G is slipped on or under the rail,l so as to bring the lip or lips a into the proper position for locking the nuts D, as shown in all the figures, especially in fig. 6. This done, the chair may be spiked or screwed down to the cross-tie, sill, or timber-hearing, by spikes b, as shown, or, in case of placing the joint of the rails between the bearings, the chair may be secured4 to the ange or base of the rail, by a gib and key, or by any other suitable fastening.

When the chair, thus constructed, is so placed that its lip or lips conform in any way to one, or more, or 4 all of the sides of the nut, it is obvious that so long as it remains in position, the nuts of the rail-bolts cannot be moved or taken on, and that they cannot get loose.

By these means, l lock the nuts perfectly, in a sim ple and secure manner, without the use of any sepa rate or complicated parts, by the prolongation or con tinuation inward and upward of the lip or lips of the chair, and bringing the same in contact with one, or
