SPECIFICATION forming part of Letters Patent N0. 760,954, dated May 24, 1904.
Application fil d January 16,1904; Serial No. 189,303. (No model.)
To all whom it may concern:
Be it known that I, ROBERT CALLAGHAN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Rail-Joints, of which the following is a specification.
The main object of my invention is to so form the abutting ends of railway-rails that the fish-plates can be'dispensed'with and that the rails at the joint will be held both laterally and longitudinally, allowing only for the usual longitudinal expansion and contraction.
In the accompanying drawings, Figure l is a perspective view showing my improvedrailjoint. Fig. 2 is a side view. Fig. 3 is a transverse section on the line 3 3,. Fig. 2; and Fig. 4 is a perspective view showing two rails detached.
A and A are ordinary T-rails, each rail having a portion of the end cut away at a, the 'cut extending through the head and web' of the rail, so that when the two rails are placed together the portion a of one rail fits against the portion a of the other, making a continuous tread for the wheels. The entire baseflange of each rail is cut away at b, leaving a portion a. When the two rails are coupled,as
in Figs. 1 and 2, the portion a of one rail will rest in the space 5 of the adjoining railf It will be noticed that the portion a of the baseflange has a bearing-surface a upon which rests the bridge-section 0 of the adjoining rail, so that while an interlock is formed the rail is supported throughout by a baseflange. The webs are perforated at a, as shown, and ordinary bolts and nuts I are used to fasten the rails together Without the use of fishplates, although in some instances fish-plates or washers may be used, if desired.
It will be-seen that I am enabled to make a satisfactory rail-joint without the use of fishplates, and the joint may be so made that the end of one rail will snugly fit the end of another, and the ends of the rails will beheld againstboth longitudinal and lateral displacement.
me to give the rail the full bearing-at its eX- treme end, and the base-flange can be fastened to the ties, makinga very secure and substantial joint.
I claim as my invention 1. The combination of two rails,each having a portion of the head and web cut away so that'one will fit against the other and having the base-flange some distance from the end recessed, so that the full portion of the baseflange atthe end of one rail will fitinto the recessed portion of the base-flange of the other rail, substantially as described.
2. The combination of two abutting rails, each rail having part of the web and head cut away and having the base-flange some distance from the end entirely cut away to form a recess, so that the full portion of the base-flange securing the two rails together, substantially as described.
3. The combination of two rails, each rail having a part of the head and web cut away at one end so that the cut-away portion of one rail will fit against the cut-away portion of the other, each rail having part of its base-flange some distance from the end recessed, forming an interlocking section at the end of the rail, said section fitting into the recess in the adjoining rail and having a bearing-surface on which rests the web. of the adjoining rail, and bolts for securing the said sections together, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ROBERT GALLAGHAN.
