JOHN WALLACE, OF ALBANY, NEW YORK.

RAILWAY-TRACK.

SPECIFICATION forming part of Letters Patent No. 498,336, dated May 30, 1893.

Application filed July 17, 1891.

To aZZ whom it may concern.-

Be it known that I, JOHN WALLACE, of the clty and county of Albany, in the State of New York, have invented new and useful Improvements in Railway-Tracks, of which the following is a specification.

My invention relates to the construction of railway tracks, but more especially to tracks adapted to street-railways; and the object of my invention is to provide a simple, cheap, and reliable construction of railway tracks in which the track-rails are secured in such manner that they are readily removable therefrom and can be easily replaced thereon. This object I attain by the means illustrated in the accompanying drawings, which are herein referred to and form part of this specification, and in which- Figure 1 is a transverse section of the track rail, chair, and fastener, showing the parts in position when the track-rail is secured to the chair, the turn-bolt for the fastener being-in elevation. Fig. 2 is a similar section of the same parts, showing the fastener turned into a position corresponding to the longitudinal slot in the top of the chair, as when the trackrail is not secured to said chair. Fig. 3 is a perspective view of one end of atrack-rail detached from a chair; and Fig. 4 is a perspective view of one end of the chair detached from the track-rail.

As represented in the drawings, A designates my track-rail, which embodies a head, 1, on which the car-wheels run, a lateral flange, 2, extending from said head horizontally, and a pendent longitudinal rib, 3, formed, on the lower face of said flange. Preferably said rib is made to extend over the entire length of each piece of track-rail. At suitable intervals the track-rail is provided with bolt-holes for receiving turn-bolts, B, for operating the fasteners, C, for securing the track-rails to the chairs the turn-bolts B and fastenings Gforming permanent attachments to the track-rail A, so as to be removable with said track-rail when the latter is taken from the chairs, and said bolt-holes should extend from the upper face of the flange 2 downward through the lower face of the rib 3, and their upper extremity should be countersunk to contain the head of the turn-bolt. The head of each turn- $erial No. 399,820- (No model.)

bolt is provided with a slot, 4, or other depression, for receiving a wrench or other implement by which said bolt can be partially rotated when occasion requires,and a fastener, O, is secured to the lower part of each turnbolt in such manner that a rotative movement of the bolt will certainly produce a corresponding motion of the fastener O. The latter is preferably made in the form of aturn-button whose opposite extremities will-when said fastener is turned in a transverse direction to the rib 3, as shown in Fig. 1-project beyond the opposite sides of said rib.

E designates a metallic chair on which my track-rail A is secured, and said chair is made in the form of an oblong box whose bottom is preferably left open. The top of said chair is provided with a longitudinal slot, 5, which extends toeach end of the chair and is fitted to receive the rib 2 of the track-rail A. Said slot is formed between the opposite edges of two inwardly-turned flanges, 6, which are integral with the chair E, and the thickness of said flanges should slightly exceed the depth of the rib 2 of the rail A, so that, when the fastener G is turned transversely in respect to the rib 2, said rail will be drawn down into close contact with the top of the chair E.

In constructing railway tracks with my track-rails and chairs, the 'latterwhich are preferably made four or five feet in length are spaced in such manner that the conjoining ends of two lengths of the track-rail will bear upon the same chair, but any required number of said chairs may be placed intermediately between two chairs on which the opposite ends of the length of track-rails have their bearing. The chairs E are placed so that the slot 5 of each chair will range in a true line with the slots of the other chairs, and, after the tops of said chairs are brought to a proper level, the track-rails A are fixed in position so that the ribs 2 will freely enter the slot 5 in the chairs E with the conjoining ends of the track-rails in close proximity. In effecting the insertion of the ribs of the trackrails into the slots in the chairs E, the fasteners 0 must be turned to range in line with the rib 2, but, when the track-rails are properly adjusted endwise, the turn-bolts B should have a quarter-revolution imparted to them,

and thereby the fasteners C will be moved in a transverse direction in respect to the slot 2 so as to securely fasten the track-rails A closely to the upper face of the chairs E. By turning the turn-bolts B, so that the fasteners C will range in line with the slot 2, the trackrails A can be released so as to be readily removable from their places.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a railway-track, the combination of a chair provided with a longitudinal slot in its upper face, a track-rail having on its under side a longitudinal rib that is adapted to be easily entered into the slot of said chair, and a turn-bolt which passes vertically through said rail and its rib and provided with a head fitted to receive an implement for turning said bolt; the lower end of said turn-bolt having a fastener secured thereto which is fitted to be turned transversely to the line of the slot in said chair so as to secure said rail to the chair; said turn-bolt and fastener fOl'lIl ing a permanent attachment to said rail so as to be removed with the latter from the chair, as and for the purpose heroin specified.

2. A device for securing track-rails to chairs, consisting of a turn-bolt, B, having a head provided with means for receiving a wrench or other implement for turning said bolt from the upper side of the track-rail; said bolt having secured to its lower extremity a fastening, 0, consisting of abar Whichwl1en turned transversely to the line of a slot in the upper face of the chair E-will secure said trackrail to the chair, substantially as herein specified.

JOHN WALLACE.
