Letters Patent No. 97,013, dated November 16, 1869.

IMPROVEMENT IN THE MODE OF ATTACHING SEATS TO WAG-0N5.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, DAVID J W'ILCOXSON, of Milan, Erie county, in the State of Ohio, have invented a new and improved Key for Securing in Place Slotted Tenons; and I hereby declare the following ,to be a full and exact description thereof, reference being had to the accompanying drawing, forming part. of this specification.

The nature or essence. of my invention consist-sin providingtbr a standard, riser, or other fixture, to be secured to its hearing or support by one or more slotted tenons, sliding beneath a plate, or in a recessed mortise,a key connected to the. standard by a slot and pin.

The arrangement and operation of the device will be fully set forth below.

In the drawings hereinhe'fin'e meutioned- Figure 1 is an elevation oiv a spring-riser or standard with its bearer and key.

Figure 2 is a plan of the bearer,';showing the mortises through the plate. and, by dot-ted lines, the recesses beneath the top plate.

The standard or riser A, supporting the spring G, is provided with the slotted tenons 0,1), and c, and the bar or bearer B, with the mortiscs a, b, and 0', ex-

tending on one side under the plate I), (as shown in i dotted lilies on iig. 1,) so as to receive the projecting portion oi'the tenons below the slot 0.

To one of'thesc tenons, as a, I apply the key F, secured to the riser above the tcnon, by means of the pin h, passing through the projecting shoulders iof the key, and through the slot It, in the riser A.

Vhen the riser or standard is lowered, for the tenons to enter the mortises, the key 1" is stopped by the plate D, the pin it sliding up in the slot k, and the key takes the position shown by dotted lines on fig. 1.

The riser A is then pushed iorward until the plate D enters and iills the slots 0, when the key F is slipped down through the plate D, behind the tenon (l, to its former position, relatively to the standald A, and thus secures all the teuons in their places, and, consequently, the standard is firmly secured upon the bearer B. I

To release it, the key F is slipped up again out of the mortise, and the standard may then be drawn back, and the tenons lifted outot' their respective moi:- tises.

By this simple construction and arrangement, I provide an efiicient key, which remains connected to the standard,bnt whielnwhatever its position may chance to he, offers no obstruction to the entrance of the tenon, and only requires to he slipped down to its place, when the standard has been properly adjusted.

The foregoing being, a description of my improved slotted tenon-key,

What I claim, and desire to secure by Letters Patent, is as follows:

In combination with the slotted teuon a, the key F, for securing it in place, when said key is held by a pin, h, sliding in a slot, If, substantially as herein set forth. 7
