TO WHOM IT MAY CONCERN:
Be it known that I, JOHN MOH-N, of Detroit, in the county of Wayne, and State ot' llllichigan, have invented. an, ImprovedlRailroad Joint; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, makingpart of this speeiiication, in which- Figure 1 is a top view of my improved rail joint.
Figure 2 is a transverse section, taken in the vertical planes indicated by the course of the red lines a: ai, fig. 1.
Figure 3 is a perspective view showing the chair spiked down upon a cross-tie ready for receiving the ends of two sections of rail.
Figure 4 is a perspective view of an auxiliary supportingand holding-down plate for the ends o f the rail sections.
lSiinilarletters of reference indicate corresponding parts in the several figures.
This invention relates to an improved mode of protecting railroad sections at their joints, and preventing the ends of the sections of rail from springing from their-seats, or being crushed or battered down by the concussions incident" to the passing and 1re-passing of trains over-them. Y
The nature of my invention consists in so constructing a railroad railchair that it shall afford a solid support for the ends of the rail sections, prevent said ends from lateral displacement, aiord a means for holding the rail ends down firmly in place, -form a portion of the head of theV rails at the ends thereof, and also receive a supportingiplate which breaks joints with the rail joint.; vall as will be hereinafter described.
The invention further consists in adapting one of the side supporting plates for the rail joint to serve also as'a capping-plate for the spikes which hold the ruil chairl down to its cross-tie, and thereby prevent the said spikes from working loose, as will be .hereinafter described.
The invention further consists in constructing upon the rail chair an elevated portion, which, when recessed into the ends of the rail sections, shall breakjoints therewith and serve as a means for supporting :and receiving the shocks of the rolling load, and preventing the crushingor lamina-ting ofthe rail at its joints,`as will be hereinafter described.
' To enable others skilled in the art to understand my invention, I will describe its construction and operation.
Inthe accompanying drawings, A A represent the ends of two rail sections which are supported, protected, and held down upon the cross-tie C by my improved method. A rectangular piece is cut out of each end ofeaeh rail section by making a vertical longitudinal cut for ashort distance into thercen'tre of the end of each rail, and thenaemoving' the piece by a transverse cut, so as to leave a rectangular recess b b', when the ends of the twG sections are brought together, as shown in iig. 1. Each end of each rail section should have a piece cut out of it, as above shown, so that when the sections are laid down upon the cross-ties the recesses at their ends will be on the inner sides of the rails. 1B represents the rail chair, intoa groove, in which the ends of the rail sections fit, so that the vertical longitudinal tacos Zn of these sections shall abut snugly against the corresponding face b of an elevation,=fa,'of the chair B. It is not designed to have the ends of the rail sections to iit tightly between the elevations a and K on both `sides of the longitudinalgroove, but to employ a separate plate, c, with a head, e', formed `on it for clamping and holding thejoi'ntagainst lateral motion. The base plate of the chair Il is extended out laterally from the outside of the rail'joi'nt, and its edge terminates in a raised lip, a', the inner edge of which is or should be parallel to the faces of the elevation a. Between this lip al and the outer edge of the supporting plate c a wedge-key, `is`drlven, as shown in iigs. 1 and- 2, for the purpose of forcibly pressing said plate c against the sides of the rail sections, and thus clamping them firmly. To prevent this key f from becoming loose the set-screw g may be used. Plate c is designed to serve as a means for holding the ends of the rail sections A A down firmly upon the base of the chair B, for which purpose that end of this plate which abuts against the rails is made 4to conform to the side thereof, as shown in figs. and 4Q Forlholding the plate c down in place I'use screw-bolts e e, which pass through oblong holes d d made through this plate and screw into the chair base. The chair B is secured down upon the cross-tie C by means of tive spikes t h, z'z'z, the latter three of which passthrough the -ilat portion k of the chair base, and have their heads countersunk therein, so as to be liush with its surface, as shown in iig. 3, so that when the plate c is applied these spikes will` he covered and prevented from drawing out or working loose.
It will he seen from the above description that the'elevated portion a, which is eonstruetedA upon the chair buse, fills up the recess left by the rornoval'of portions of the rail sections, and forms a. splice forlthe joint, and also a portion of the rail table. In practice this elevation a will be faced with steel, so es to rend'ert more durable and less liable to be `crushed. I am aware that it is not new to splice rail sections at their joints, by euttingout portions of such sections and inserting plates which breek joints with the rail joints. Suchplnt'es require to be secured-to' the rails by trzinsvers'e bolts, which are constantly working loose. By my invention the rails are made much stronger and more durable at the joints than nt-'anyother point, by transferring the weight and shocks of the rolling loa-d from the rails to the solid chair-pieces a :it every joint.
What I claim as new, and desire to secure by Letters Patent, is
1. A railroad chair which is constructed with u solid portion, a, :L'slotted base, j, an elevated table, K, and an abutting lip, a', adapted for receiving the notched rail-sections A A, a supporting and covering plate, c c',
`and a key, f substantially as described.
2. The mode herein described of securing the chair by means of the spikes t' z' for the purpose set forth. 1 JOHN MOHN. Witnesses JOSEPH KUHN,
