SEAT Fon HARVESTERS 0R THE LIKE.

SPECIFICATION forming part of Letters Patent No. 685,663, dated October 29, 190.1.

Application lod May 8, 1901. Serial No. 59,206. (No model.)

4zen of the United States, residing at Cleveland, in the county of Cuyahoga and State 0f Ohio, have inventeda certain new and useful Improvement in Seats for Harvesters or the Like, (Case 0,) 0f which the followingis a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to pressed-steel seats such as are used on cultivators, harvester-s, and various agricultural machines.

Its object is to provide a seat which while being simple in construction shall have the material disposed where it is most needed, s0 that an equally strong and durable seat may be made from less material, thereby reducing the cost. L Y

A further object is to provide means which shall at once strengthen the seat and prevent its turning on its support.

These seats are commonly supported on the ,edge of a U-shaped bar, through the opening of which a bolt passes to hold the seat in place.

Such bar allows the seat to be adjusted back and forth a considerable distance, as is frequently desirable; but it gives a very slender support. to remedy this, providing a simple and etticient reinforcing-plate at the central'portion of the seat, arranged to strengthen the seat where strength is needed, so that the rest of the seat may be made of lighter material, whereby thetotal weight of the seat and reinforcing is less than of a single seat stamped from one piece of material of suftlcie'nt thickness to withstand the Wear, it being impracticable to have the stamped seat of material thicker at one point than at another. I place the reinforcing -plate within a depression made in the seat proper, while in order to prevent the seat turning on its supporting-bar without additional members I form on the under side of the seat an integral projection which engages the supporting-bar, delining the position of the seat thereon. The bending of the seat to make the depression for the The present invention is designed reinforce and the limitingprojection are of themselves an advantage in making the seat more rigid.`

The drawings fully illustrate my invention, y

` At its central portion it is depressed` or rev cessed downward, as at o..

W'it-hin this cen- It is adapted to be stamped fromasintral depressed portion is a reinforcing-plate B,conforming to the size of the recess. This reinforcing-plate is made, preferably, of sheetV metal ofthe propery thickness to give sufficient strength to the central portionfof the seat. The depression ct is of such depth that a reinforcing-plateofthe proper thickness a will have its upper surface substantially flush with the upper surface of the seat adjacent thereto. depression by rivets C, which are preferably collntersunk at theirupper ends; On the under side of the seat isA the integral downward projection or'bossa', which is prefer ably elongated, as shown.

The reinforcing-plate is heldin this With such a construction as described the seat proper may be made of very light mate'- rial and the reinforcing-plate of whatever thickness is necessary to provide the requisitey strength, whereby the total weight of the seat and reinforce by being more efficiently placed may be less than that of a seat made in one i 1.
