To ALL WHoM 1TA MAY GONGERN;

Be it known that I, HENRY McCAN, of Hanover, in the countyhof Columbiana, and State of Ohio, have invented certain new and useful Improvements in Railroad Tracks; and I do hereby declare that the following is a. full and complete description of the'same, reference being had to the accompanying drwings,imeking a partof this specification, in whichv' Figure 1 is a. top view of tbe'track.

Figure 2 is u. side view.l

Figure3 is an end view. v l

Like letters of reference refer tolike parts in the views.

' The rails of this track are constructed in two sections,A B, iig. 2; A being tbe upper section o1' treadral, on which the wheels iun,land B the lower section or base-raiLbeth of which are of thepeculinr shape shown in fig. 3. Extending along the upper side of the base-rail is a rib, AC, to which is fitted the upper rail A, by means of a corresponding groove made in the under side of tbeupper rail. The two rails are then fastened together by bolts a, and, when thus tted andbolted, are shown invv figf. D is an iron tie and chair, on which the rails are placed. The ends of this tie are so constructed as to form a. chair, E, by whichthc base-rail is secured. F are stay-bolts or braces. These .bolts are provided with adjusting-nuts G, one on the inner side of euch rail, and one on the outer, the purpose of which is to regulate thel lateral trend of the rails, and thereby maintain their-'proper relative distance from eachother. Y f

The manner of laying this track is as follows The ties C are buried in the ground,'nt'sucb e depth as to include all of the base B below the stay-bolts. The base-rails are then laid on the ties, and properly secured in the chairs, the number of which being more or less, es the nature of the ground may determine. The trend of the rails, being properly adjusted bythe bolts, thelrond is then grnv'elled or bellasted in the usual wey. The base or ground-'rails of the road, cn being thus constructed, the trend-rails A-are then laid upon them and boltedto the same, as'above described, und shown in thedrawing.

' A road thus constructed dispenses with the use of the weiden cross-ties, which are ever rotting' and insecure.

In the rond, the'base-rail having a. broad ilat surfnee rests upon the ground in part, as' wel-l as upon the iron crosstics or chairs, thereby requiring a less number of cross-ties for the support of the rail, and which, not being subjected to rapid decay, is much stronger, safer, and dum-ble.A

What I claim as my improvement, and desire to secure by Lettel's Patent, is

The construction and arrangement of the base and tread-rails A B, in combination with the chairs and ties D E and adjusting-bolts F, in the manner substantially as set forth.
