COMBINED ANGLE-BAR NUT-LOCK AND BASE-PLATE FOR RAIL-JOINTS.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed. SeptembenlZ, 1907. Serial No. 392,486.

To all whom it may concern:

Be it 1: nown that I, HENRY N. Nonrnorr, a citizen of the United States, residing atthe city of Columbus, county of Franklin, State of Ohio, have invented an Improvement in a Combined Angle-Bar N u't-Lock and Base- Plate for Rail-Joints, and do hereby declare application of same, as will be hereinafter,

more fully described and particularly pointed out in the claims and'the accompanying drawing. 5

in the accompanying drawing the reference characters indicate same parts of the invention in the several views.

Figure 1 represents a rail-joint with the usual splice-bars, bolts, nuts, and cross-ties, showing a front elevation of the angle-barnut-lock and base-plate in position and the manner of fastening the same. Fig. 2 represents a detail; sideielevation of a rail-joint with the angle bar-nut-lock in-position. Fig. 3 is a sectional'view taken on a plane indicated by the line aa. Fig. 4 represents a 'detail elevation of the base-plate, showing the location of the holes for the admission of the fastenin spikes to the cross-ties. Fig. 5 is a sectiona view of the base-plate, taken on a plane indicated by the line b-b.

In the embodiment of my invention, I employ in combination with any kind and shape if rail-joint-bolt-nuts, a sin le continuous ngle-bar A, made of meta cast, rolled, forged or stem ed and consistinm of the verthe angle-piece This angle-bar A, when laced in right position is located on the rai -joint (as shown in Figs. 2 3) on the same side with the bolt-nuts, running through the entire length of the railjoint in one continuous piece and is shaped in such a way, that the vertical leg a of the angle-bar A, lies close to the face of the splice-bar and the'angle-piece b lies upon the foot of the rail, forinin a ood fitting connection between the splicear, rail and the angle-bar A.

The vertical leg a of the angle-bar A is provided on the upper edge with angular slots 0 for the purpose of forming a receptacle for the bolt-nuts; the intermediate parts of the vertical lega, situated between said angular slots 0 constituting locks 0, these locks c standing with their vertical sides parallel to the vertical sides of the bolt-nuts are bound to hold and keep the bolt-nuts secure in position, therefore preventing the said bolt-nuts from turning or moving absolutely.

The angle-bar A is not limited in lengthto the len th of the rail-joint it may run over the rai -joint in any convenient len 'th; in height the angle-bar A is limited .to t 1e section of the rail or rail-joint being used.

The vertical leg (1 of the angle-bar A does not reach through the entire length up to the head of the rail, only the center part of said vertical leg a situated between the two center' slots 0 forming the center lock 0 is provided with an upward extension d nee y abutting with the projection e under the head of the rail; the parts of the vertical leg a lo catedto the right and left of said upward eX- tension at reaching high enough to cover the part of the bolt-nuts necessary to keep them secure in position. The vertical leg a is further provided on the outer side with a stiffening rib f, this stiffening rib fstarts on the upper end of said vertical leg a terminating just above the lower end of the slots 0 reinforcing the intermediate locks 0 through the entire length of said vertical leg at; on the angle point the angle-bar A is rovided with a orizontal lip :g acting as a iller in the space at the termination of the splice-bar and the foot of the rail.

Both ends of angle-piece b of the angle-bar A are further provided with projections 7b, the center part of said angle-piece b has a similar projection i with slots cut in, which slots 7' serve the purpose of receiving the spikes of the rails; these slots 9' are only large enough to allow the spikes to rest in.

The end projections h and the center projections i are flattened on their tops so as to form a solid base for the head of the fastening spikes.

The plate B Fig. 4, being an integral part of the device consists of a plate of uniform thickness, made of metal, cast, rolled or stamped, shaped rectangularly and is provided near the ends with holes 70 and Z, these holes kand l are square and serve the purpose of allowing to pass the fastening spikes through, to be embedded in the cross-ties. I

The holes 7c placed on the front of the plate B, have to correspond with the slots in the center projection i of the angle-piece b, the holes Z on the back end of the plate may be placed in any suitable space; the parallel distance between the holes is and l to be govterned by the section of the base of the rail, the late B is to be ap lied to.

Tfleplate B is providiad on one of its sides with a rib m, this rib m, when the plate B is placed in right position stands parallel to the angle-bar and with its inner side fitting snugly to the lower art of the central projection i of said ang e-bar A acts as a stop against any forward sliding motion of the angle-bar A; it can be clearly seen from the fore oing described arrangement, that once the olt-nuts the angle-bar and plate are fastened in place, any moving or displacing of the angle-bar is practically prevented; in upward direction, through the lower end of t je slots c and by, is upward extension (Z of the angle-bar A against the rail-head; laterally both ways,- through the slots 0 or looks c and the bolt-nuts therein and through the horizontal projections h on both ends and the center rojection'i on the foot of the anglebar and t e corresponding spikes driven through the baseplate B in the underlying cross-ties; and in a downward direction,

1 throng through the horizontal rib m on the front end of the j late B and the fastening spikes driven h the plate B in the underlying crossties; therefore the angle-bar A safely secured from moving in whatever direction, is bound to prevent the bolt-nuts from turning or moving; consequently the purpose of the device for a safe, simple and absolute lock for railjoint-bolt-nuts is accomplished.

Although I have s ecially described my invention with regar s to the construction and relative arrangement of the several elewhat I claim as new and useful and desire to procure by Letters Patent is;

1. A lockin bar for rail joints comprising a longitudinal y extending. late having lockin recesses in its upper e ge adapted to receive the nuts, end flan es and a central flange extending outward y from the lower edge of the plate to provide means for securing the said plate to the ties and a centrally located member projecting upwardly from the upper edge of the plate to engage the rail flange and said plate also having stren thening ribs extending longitudinally of the plate and in line with the locking recesses substantially as described.

2. A lockin bar for rail joints comprising a longitudinal y extending Cpglate having lock-' ing recessesin its upper e e adapted toreceive the nuts, end flan es and a central flange extending outwarifly from the lower edge of the plate to provide means for securing the said plate to the-ties and a centrally located member projecting upwardly from the upper edge of the plate to engage the rail flange and saidplate also having strengthening ribs extending longitudinally of the plate and in line with the locking'recesses, a plate having a 1projecting rib extending upwardly on one 0 means for holding the locking bar secure in position substantially as described.
