UNITED STATES PATENT OFFICE.
THOMAS J. ALEXANDER, OF WESTERVILLE, OHIO.
IMPROVEMENT IN WAGON-SEATS.
Specification forming part of Ietters Patent No. 144,492, dated November 11, 1873; application filed March 15, 1873.
To all whom it may concern:
Beit known that I, Tnos. J. ALEXANDER, of Westerville, in the county of Franklin and State of Ohio, have invented certain Improvements in Wagon-Seats, of which the following is a specification My invention relates to that part of a wagonseat wherein the spring is produced by the boards which form the seat -board, and for which Letters Patent were granted to me November 7, 1865.
In this arrangement I use four (4.) instead of two (2) boards, which are so arranged and connected that their combined action will produce double the amount or length of spring, thus preventing an overstra'm of the springing qualities of the timber, and whereby the action and durability of the seat are greatly improved.
Figure 1 is a top view of the seat which embodies my invention. Fig. 2 is an end view. Fig. 3 is a transverse view of the center of the seat at the dotted lines, which represent the under cleats E E.
A, B, C, and D are four (4) slats or boards of the .requisite length, breadth, and thickness, that their combined widths will make a seat the width required. The two middle boards, B and C, are attached together firmly at their ends by the upper and under cleats, F and G, as shown in Figs. l and 2. The outer boards,
A and D, are connected to the inner boards, Ato B, and D to O, by the center under cleats, E E. rPhe cleats are cut so as to pass each other, and thus hold the boards B and C to y their relative positions when under pressure,
when in action, as shown in the depressed view in Fig. 2.
By this arrangement, one-half the spring required is transmitted from the outer boards, A and D, to the inner boards, B and O, through the connection made by the under cleats, E E, thus producing all the spring required, and not overtaxing the springing `qualities of the timber, and, as the boards are but half the width, and equivalent to double the length, as
when constructed with but -two boards, they must, of necessity, be proportionally thicker, thus preventing atendency to check and split, which is the case when made with but two (2) boards, as they must, in that case, be made thin, to give suicient spring. l
I do not in this claim the spring produced by the twist of the boards that form the seat-board. y
What I claim as my invention is- In a wagon-seat, the knees J J, in combination with the boards A, B, O, and D, and the cleats E E, as and for the purpose set forth.
THOS. J. ALEXANDER.
