RAIL-CHAIR, TIE-PLATE, TRUSS-JOINT, AND lOlNT-FASTENING.

SPECIFICATION forming part of Letters Patent No. 474,127, dated May 3, 1892.

Application filed J'uly 25, 1891.

.To all whom it may concern,.-

Be itknown that I, FREDERICK H. HEATH, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Improvements in a Combined Rail-Chair, Tie- Plate, Truss-Joint, and Joint-Fastening, of which the following is a specication.

My invention relates to means for joining, supporting, and fastening railway-rails; and the object of the invention is to provide a tieplate which shall be adapted to extend over and across two ties and which shall also have and constitute the rail-chairs; also, a trussstrengthening plate, and thereby adapting it to firmly supportthe meeting ends of two rails, and, further, to provide fastenings by which the rails may be secured-on the plate without the `necessity of drilling holes through the rails, as is usual with other fastenings, and, further, to provide a device of the class described which, while capable of fulfilling all of the purposes for which it is designed, will,

owing to its construction and the arrangement of its integral trusses, be adapted for embodiment within a minimum size and weight.

My invention consists in general in a railjoint strengthened by trusses of a novel construction and arrangement and a particular fastening therefor, whereby the rails are secured upon the plate, all substantially as hereinafter described, and particularly pointed out in the claims.

My invention' will be more readily understood by reference to the accompanying drawings, in which- Figure 1 is an under side view of my improved rail device. Fig. 2 is a plan View of the same. Fig. 3 is a side elevation of the same. Fig. 4 is a transverse section on the line wx of Fig. Figs. 5, 6, 7, and 8 are de-` Serial No. 400,712. (No model.)

to form the broad chairs 5 of suchalarge area that the rail is prevented from tilting and the edges thereof cutting into the ties. The center portion 6 of the rail-joint is substantially the same width as the rail-base 7. It will be seen that a simple tie-plate of the thickness shown would not be sufficient to support the meeting ends of the rails, so as to prevent sagging and the depression of the rails at the joint. I therefore provide a truss in and on the plate formed integrally therewith, and having the parts 8 formed on the top of the plate and spreading out to embrace the sides o1' edges of the rail-bases and the lower part dipping or extending below the plate and between the ties. This lower part of the truss is divided into or rather formed of the middle web 9, the rib 10 thereof, and the diagonal and transverse parts or brackets 11 and 12, respectively.

It will be seen that the main part of the brace or truss is the part 9, having the strengthening-rib 10. The diagonal and transverse brackets or trusses form extensions of this main part and terminate in the top trusses 8 which, it will beseen, extend inward through the line of the transverse trusses. The diagonal trusses are preferably curved and at their outer ends are brought as near as possible into line with the top truss-extensions. The ribs 13 form continuations of the trusses 8, and make the sides of the rail-chairs to prevent the sidewise movement of the rail. As shown, the greatest height of each top truss 8 is just above the point where the diagonal braces meet the tie-plate, thereby greatly strengthening the tie-plate at the point above the edge of the railroad-tie and preventing the bending of the tie-plate at such points.

The use of the top trusses makes possible the employment of the very short lower truss, thereby allowing the tiesto be brought closer together, and hence greatly increasing the stability of the rail-joints. The object of the transverse trusses 12 is to prevent the bend- 95 ing of the plate on a line to the diagonal brace, or, in other words, the twisting of the tieplate. The tie-plate is secured upon the ties by the spikes 14, driven down in the notches IOO rail-chair parts of the plate. A longitudinal movement of the rails is prevented by use of the lugs 16, provided in diagonally-opposite position on the plate. The rails are provided with the notches 17 of a greater length than the width of the lug, as shown, and adapted to receive the same. The dii'ferencelietween the size of the notches and the lugs is sufficient allowance for expansion and contraction. The rails are held securely upon the tie-plates by the clamping-boxes 18,arranged one on each side, as shown, and provided with the inclined or wedge-shaped inner sides adapted to engage the inclined top of the railbase and the oppositely-inclined surfaces 19 of the middle part of the plate between the transverse trusses. The openin gs 2O are provided throiigh this part of the plate and are adapted to admit the bolts 2l., passing through the same and through the clamping-blocks 18, wherein said bolts are secured. The distance between the outer corners of the rib is greater than the widest bolt-head employed, and the distance between the lower edges of the ribs is less than Ithe smaller. that the bolt-lieads 25 will rest upon the inclined sides 24 of adjoining ribs and can never touch the side of the clamping-block. Hence the rotary movement of the bolt, which would act to loosen the nut 26, is wholly prevented. It is obvious that any sized bolt may be eniployed for tightening vthe clamping-blocks and holding the same in place. It will be seen that by this means I provide a trussfastening that is simple and inexpensive in construction, that securely supports the rail at the joint, and that does not require the making of any holes through the rail for the purpose of securing them. If it is necessary to cut off a rail or to use ashort piece thereof, it is not necessary to incur the expense of drilling holes through the rail.

All that is necessary to do to the rail to adapt it to be used with this fastening is to cut a notch or recess in the base for the purpose of interlocking it with the projection or lug 16.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
