Patented May 18, 1909.

Application filed July 13, 1908. Serial No. 443,221.

To all whom it may concern:

' Be it known that I, EDMOND L. BEAN, a

j'citizen of theUnited States, residing fat Hydesville, in the countyv of Humboldt and State ofCalifornia, have invented certain new and useful Improvements Seat- Springs, of which the following is a specification, reference being bad to the accompany-- ing drawings.

' This invention relates to improvements wagon seats and-more particularly to springs therefor.

- The object of theinvention is to improve theconstruction of seat springs and toprovide one which will occupy but little, space and not project beyond the front ai'id rear edges-f the seat and be in the Way of the o'cc'upant thereof, nor inwardly beneath the central part of the seat, and interfere with the loading of the wagon.

With the above and other objects in view,

4 as will'hereinafter more fully appear, the invention' consists of'the novel'features of construction and the combination andarrangement'of fparts described in the following specification and illustrated in the accompanying drawings, in WlllCl1.-

Figure 1 1s a front elevation of the improved seat;.Fig. 2 is a side or end elevation of thesarhe; Fig. 3 is a vertical transverse section through the spring; and Fig. 4 is a horizontal section taken on the plane indicated by the line 44 in Fig: 3.

The improved seat spring is designed to take the place of'the' usual bowor leaf springs now in.general use on farm wagonsbnt it may be adapted for use on carriages,

their fastening bars 2, o

buggies and other vehicles. The s ring comprises an oblong coil 1 constructs of square spring steel and upper and lower bars 2, 3 between which the spring is arranged and to which its ends are effectively clamped by U- shaped bolts or clips 4. he improved springs are adapted 'to take the place of the orpdinary leaf springs above mentioned and the coils 1 are therefore made comparatively narrow and of slightly less-length than the width of the seat S. Said springs and also are made of less width than the upper edges of the sides of the wagon body so that they will not project into or above the space within the wagon body,

thereby permitting a portion of the s ace in the Wagon body beneath the seat to be oaded up to and above the plane of the top of the body. ..By constructing .the springs in this manner they will be very little broader than .the oldstyle springs. and will not project be yond the front; and rear edges of the seat and will therefore not interfere with the loading of the Wagon or the driver climbing up upon the seat-and descending from the same, as is the case with the old style leaf springs. As above explained, this construction leaves the space beneath the central part of the seat open and permits a high loadto be laced at t 1e front end of the wagon body. y making the coil springs 1 of square steel their ends may be effectively clamped to the upper and lower bars or boards 2, 3 and side springing will be overcome to a certain extent, and par.

ticularly when the springis made rectangular in cross section and itsiwidest part is disposed laterally or horizontally. The upper and lower bars 2, 3 are securedto'theseat S and the wagon bodyVV by, bolts 5 arranged adjacent to the center of said bars, as clearly shown in the drawings. Cleats 6 may also be provided uponthe lower bars 3 to engage the inner face of the sides of the wagon body .and relieve the bolts 5 of a lpart of the strain.-

From the foregoing it wi beseen that the improved spring is simple, strong, durable and practical in construction and that it is exceedingly compact and will effectively overcome the objections to the old style leaf springs.

' Having thus described the invention what is claimed is:

The combination with a vehicle body having a seat, of bars secured to the underside of said seat adjacent to the ends thereof, bars secured to the Sideboards of the vehicle body and disposedin s aced relation tothe bars u on the seat, an springs disposed between t e bars and extending longitudinally of the vehicle body, said springs each being formed. from a single piece of metal square cross sectionally, said metal being bent to provide elongated convblutions arranged in parallel spaced relation-t0 each other, the side portions of the convolutions of the springs e tending'lon itudinally of the side boards of the vehicle ,ody. 7|

In testimo'n whereof-I hereunto aflix my signature in{ t' epresence of two witnesses.
