CHARLES FREDERICK BLAKESLEE, OF RAIPATEE, ILLINOIS.

WAGON-SEAT.

Application filed November 19, 1913.

To all whom it may concern:

Be it known that I, CHARLES FREDERICK BLAKESLEE, a citizen of the United States, and a resident of Rapatee, in the county of Knox and State of Illinois, have invented a new and Improved VVagon-Seat, of which the following is a full, clear, and exact description.

My invention relates to a wagon seat of the type mounted on the seat springs, and more particularly involves a means for so suspending the seat on the seat springs that the said springs may respond to the lateral movements of the wagon body without imparting lateral movement to the seat.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of awagon seat embodying my invention; Fig. 2 is an end view of the seat; Fig. 3 is a transverse vertical section of the seat detached from the springs; and Fig. 4 is a detail in vertical section, on the line 44: of Fig. 3.

My invention is applicable to wagons and similar vehicles, and is here shown as applied to a farm wagon A, having a known form of elliptical springs B, the springs being shown with the usual top piece C on which, ordinarily, a board seat, which is indicated by the numeral 10, is dlrectly secured. In my invention the seat 10 is supported above the springs, novel means being provided for the purpose.

On the under side of the seat proper, 10, depending hangers 11 are provided, which are united by a transverse member 11, the device thus being in the form of an arched bar, one of said bars being rigidly secured to the seat 10, near each end thereof, by bolts 12. The lower ends of the hangers 11 are formed with holes 11", that receive the out-turned ends 13 of hangers 14, said hangers being formed on a rocker bar 14:, there being one of such rocker bars for each end of the seat. The bars 14: are rockably mounted in suitable bearings 15 which are supported beyond the seat hangers 11 so as to form an angle therewith on longitudinally-ranging supporting bars 16 disposed below the seat 10. The longitudinal bars 16 Specification of Letters Patent.

rest near their ends on the pieces C secured to the springs B, and are suitably secured to be rigid with the said pieces C.

The rocker bars 1 1 with their hangers 11 and out-turned ends 13 provide rockable crank arms and the bearings 15 are disposed out of vertical alinement with the hangers 11, being set to one side of the latter, so that the crank arms will be disposed at an angle to the hangers and the centers of movement of the arched rocker bar and crank members 13 will be out of vertical alinement.

With the described construction, the arrangement of the parts when the weight of the driver is imposed 011 the seat 10, the inertia. of the seat and the drivers weight will tend to maintain the seat and its hangers 11 against movement on the crank hangers l4: and thereby eliminate the side lash or lateral movement of the seat, and at the same time the vertical cushioning eifect of the seat springs B is fully utilized. It will, therefore, be perceived that the only function of the hangers 11 and the rocker bars 13 is to maintain the seat on a certain height above the side pieces 0, so that the direct shock of the cushioning effect of the springs may not be directly transmitted to the seat itself but be absorbed through the side pieces C, the rocker bars 13 and the seat hangers 11.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a vehicle seat, a seat proper, springs at each side of and below the seat, cross bars on said springs connecting the same with each other and extending transversely beneath the seat, rocker arms hung on said cross bars between the springs, and depending hangers rigid with the seat and pivotally supported at their lower ends on said rocker arms, each of said rocker arms being mounted on the cross bars to one side of and adjacent a hanger and disposed at an angle to the latter to permit fleXure of the springs and vertical movement of the connecting cross bars independently of the seat.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES FREDERICK BLAKESLEE.
