UNITED STATES PATENT OFFICE.

ISAAC B. HOWE, OF NORTHFIELD, VERMONT.

RAILROAD-CHAIR.

Specification of Letters Patent No. 24,639, dated July 5, 1859.

To all whom 'it may concern:

Be it known that I, I. B. HOWE, of Northfield, in the county of Washington and State of Vermont, have invented a new and Improved Joint-Chair for Railroad-Rails, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is a plan; Fig. 2, an elevation; Fig. 3, a section upon the line A, A, of Fig. l; Fig. 4, a View ot' my chair detached.

My invention consists in a peculiar one lip chair in connection with a fishing piece secured permanently to the sleepers and a method of securing both chair and rail in place by a single bolt the whole so arranged that on withdrawing the bolt the rails and chair may be removed without the necessitjT of disturbing the fishing as will now be more fully described.

The chair B, is seen in section in Fig. 3, and is made with a single lip C, and a bolt hole f, as seen in Fig. il.

The rail joint is caused to fall between the sleepers, the chair being supported by a bridge I, formed of plank of suitable thickness which is secured at each end to the sleepers D. The fishing piece E, which is spiked down through this plank permanently to the sleepers has a rabbet cut in its under surface to accommodate the chair as seen at i, (Fig. 2) and a hole to receive the bolt H, which passes down through the fishing, through a notch in the hase of' the rail, and through the chair and the bridge I, beneath which it is secured by the nut K. It is obvious that this single bolt in connection with the single lipped chair and the permanent fishing piece holds the adjacent ends of the rails in place and that on the bolt H, being removed the chair may be knocked out and the rails set free.

Among the advantages arising from the above described arrangement of chair and fish piece may be enumerated the following: First, the elastic bed thus afforded to the chair saves the ends of the rails which are no longer battered and destroyed by the hammering of the wheels; second, the vertical displacement of the ends of the rails caused by the heaving or sinking of a single tie is but half what it would be were the joint chair placed immediately over the sleeper; third, the rails may be removed without disturbing the fishing by simply withdrawing the bolt H; fourth, the rails will not creep as the bolt H, passes through a notch in the base of the rail; fifth, there is no rocking of the joint tie to raise and depress the ends of the rails and expose them to the blows of the passing wheels; sixth, it costs no more than the ordinary cast iron chair while it is easier taken care of and not so liable to get out of repair.

Vhat I claim as my invention and desire to secure by Letters Patent is- The one lip chair, secured by the single bolt, in combination with the permanent fishing piece arranged and Operating in the manner set forth for the purpose specified.
