SPRING-SEAT Fo R VEHICLES.

S?EGIFIGATION forming part of Letters Patent No. 233,689, dated October 26, 1880.

Application filed May 18, 1880.

To all whom it may concern:

Be it known that I, JAMES OOoNNoR, a citizen of the United States, residing at Jackson, in the county of Cape Girardeau and State of Missouri, haveinvented certain new and useful Improvements in Wagon-Seat Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a front view, showing one end of a wagon-seat with my improvements attached thereto. Fig. 2 is a view of the blank for forming the spring. Fig. 3 is a perspective view of my improved spring and attachments.

Thisinvention relates to that class of springseats for vehicles in which two leaves-one at each end of the seat-are employed in connection with means for suspending the seat to the wagon-body.

The object of my invention is to do away with unnecessary members, and to simplify and cheapen this class of springs for vehicles.

Therefore the improvements consist in making each spring from a single blank or leaf of metal, which is curved at the ends to form elastic loops, and then returning the ends in-- wardly toward the center and securing the free ends to a wooden bar, to form a base for the spring to rest on and to sustain the weight imparted to the spring through the seat.

It also consists, in combination with the above-named devices, of the bent hooks attached to the under side of the base-bar, as will be hereinafter more fully set forth, and pointed out in the claims.

In the annexed drawings, forming a part of this specification, the letter A represents a seat ofa vehicle, which may be made in any of the known forms attached to the bolsters B B. (Only one shown.) To the under side of the said bolsters, arranged at each end of the seat, are attached the springs O C.

By reference to Fig. 3 of the drawings it (No model.)

will be seen that the springs G G are of a peculiar construction-that is to say, each spring is made from a blank or leaf of metal of a proper length, (see Fig. 2,) which is capable of being worked into the shape hereinafter described.

The blank is bent and shaped at the middle to conform to the curved under portion of the bolster. The ends are then bent and curved so as to form the elastic loops D at intermediate points in such a manner that the inner faces of the plate shall not touch each other and the extreme free ends are carried forward inwardly in a line parallel with the bolster until their ends shall nearly meet or be directly under the ends of the bolster, where they are firmly attached to the upper surface of the wooden bar E.

The bar E forms a base for the spring to rest on and sustains the weight imparted to the spring through the seat.

The loops D at each end of the spring aid in relieving the strain upon the main portion of the spring, and have the desired efl'ect of preventing the springs from snapping at these points under heavy pressure.

To the under side of the bars E, near each end and directly under the ends of the curved springs, are attached hooks F F, made of sheet metal, which are secured to the bars by the same rivets or bolts that secure the free ends of the springs. The upper ends of these bars, formed with hook-shaped catches b b, are designed for the purpose of passing over the sides of the wagon-body to sustain the seat.

It will be observed that the bars E not only act as a means of preventing the displacement and strain of the springs in alateral direction, but that they afford a firm foundation for the spring plates or leaves and additional security to the permanence and firmness of the base of the suspension-hooks which is not attained when the suspension-hooks are merely bolted or riveted t0 the springs.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A spring for a wagon-seat, consisting of a single leaf formed with elastic curved ends, and havingthe unconnected ends returned inwardly toward the center, where they are seand hooks being secured to the bar by the'same cured to a Wooden bar forming a base for the rivets or bolts, as described.

spring ends, as described. In testimony whereof I affix my signature in 10 2. The combination, with the bolster B and presence of two witnesses. 5 base-bar E, of the single-leaf spring 0, having Witnesses: JAMES OOONNOR.

the unconnected ends returned inwardly to- HENRY R. ENGLISH, ward at center, and the hooks F F, said spring G. O. PEPPER.
