Letters Patent No. 76,959, dated April 21, 1868,

SHIPPING RAILS FOR GARRIAGE-SEATS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL TOOMEY, of Wilmot, in the county of Stark, and State of Ohio, have invented Improvements in the Shifting Rails of Carriage-Seats; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification-- Figure 1 being a top View of a carriage-seat provided with my improvements.

Figure 2, a vertical section, in a plane indicated by the line a: a, fig. 1.

Figure 3, a vertical section,in a plane indicated by the line y y, fig. 1.

,Like letters designate corresponding parts in all of the figures.

' These improvements are upon the invention which was patented by A. S. Grant,May 17, 1864.

In that invention, the arms G C of the shifting rail are secured at the front end by notched projections or gibs, c c, on the under side thereof, fitting over the edge of a mortise in the brackets a a of the seat, and held there tight by wedges, d d, on latches D D. The disadvantage of that device arises from the narrow edge of the mortise, against which the wedge d bears, allowing the arms 0 C to twist or sway sidewise, and towork the wedges loose.

My improvement here consists in forming a cheek-projection, G, on the under side of the bracket a, at the inner edge of the mortise, against which the wedge 01 bears, on the side opposite to the gib c. The extent of this projection may be equal to that of the wedge and gib, as represented. This simpleimprovement gives the necessary firmness to the arms C G, and obviates the working out of the latch-wedges d d.

Another improvement -in the attachment of the shifting back, in connection with the front fastening, as above described, consists .in the construction of the back hooks, as represented in fig. 3, for connecting'with the rear brackets, b b, of the seat.

A tenon, g, rectangular in form, fits the full size of the mortise in the bracket, at the base or upper end thereof, while the front edge slopes backward therefrom, and the hook 72. projects backward, at right angles from the tenon. Also, there is a wide shoulder, f, on the front side of the standard B, bearing on the bracket b by a spring pressure, produced by the bending down of the arms 0 C to their fastening. This arrangement produces a very firm shifting back, and one that does not work loose.

' What I claim as my invention, and desire to secure by Letters Patent, isv The projection G, on the under side of the bracket a, at the inner edge of the mortise, in combination with the gib G and wedge d, substantially as and for the-purpose herein'specified.

I also claim, in combination with the gib and wedge-fastening at the front, the square hook-tenons g g, and shoulder f, bearing with a spring pressure upon the brackets b b, substantially as and for the purpose herein set forth.

The above specification of my improvements in the shifting rails of carriageseats signed by me, this 20th day of February,1868.

SAMUEL TOOMEY.
