Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed June 6, 1911. ,Serial No. 631,672.

To all-whom it may concern; I

Be it known that I, NATHANIEL I. RILEY, a citizen of the United States of America, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Spring-Seats, of which the following is a specification.

This invention pertains to spring seats and has for its object to provide a substantial and durable spring seat for drivers and passengers on vehicles.

The invention is especially valuable to locomotive engineers", motormen and drivers of dray and freight wagons. A modified form of the invention as shown in the drawings is especially valuable to motormen on electric street carsand the like as a foot, cushion.

In the accompanying drawings I have shown the'application of the invention as a spring seat. 7

. Figure 1, is a top view of the seat and back complete, Fig. 2, is a bottom view thereof with back broken-away, Fig. 3, is a combined 'front and sectional view of the seat and back complete, Fig. his a side View thereof, Fig. 5, is a detail view of the end of one-of the bottom supports together with the mechanism whereby the back of the seat is connected therewith, Fig. 6, is a brokenaway side View of one of the bottom supports together with an end view of the headof a bolt extending therethrough and of a plate extension leading from a tube inserted in a bore in the support. Fig. 7, is a combine top and sectional view of Fig. 6 and disclosing a coil spring and a broken-away view of a rod extending horizontally through the support.

Steel strips, 10paralleling each other are arranged horizontally and secured to the supports 11. Tubes 12 with plate extensions 13 are set into bores in the sides of the sup-' ports 11. Rods .14; with heads 15 on each end connect the supports 11 at positions underneath the horizontally arranged steel strips 10, such rods being provided with turnbuckles 16 intermediate the ends thereof, and coil springs 17 encircling the same at their ends. The rods 14 passthroughl the .inner sides of the supports 11 and the inner ends of the tubes12 and the coil springs. 17

encircle the same between the heads 15 thereof and the inner ends 18 of the tubes 12.

The back of the seat consists of horizontallyaarranged steel strips 10 secured to the uprights 19 pivoted to the supports 11 as at 20. The uprights 19 extend through the loops 21 secured to the supports 11 in which they have a lateral play. The steel strips 10 and 10 are made of such width and thic ness as to readily give under the weight of a man so as to have a springing effect. For instance, the strips 10 would give downwardly under a mans weight to approximately the position shown by the dotted line 10? and the strips 10 to approximately" the position shown by the dotted line 10 The back of the seat composed of the horizontally arranged strips 10 and the uprights19 is supported by the side arms 22 secured'to the front ends of the supports 11, and the uprights 19 as at 23 and 24 respectively. The horizontal supports 26 to which theback of the seat is secured areloosely engaged by the strips 25 and 27 secured to the supports 11 as a means of conmeeting the relative. parts without interfering with the free action of the springs.

I have shown the complete structure mounted upon feet 28.

Connecting slats 29 may be used to bind the steel strips 10 and 10 intermediate the ends thereof. Openings 30 may be made in the steel strips 10 and 10 whereby pads may be secured to the seat and back re spectively.

The coilsprings 17 at the ends of the rods 14 furnish a force to return the steel strips 10 to the horizontal after the 'weight upon the seat has been removed, and the coil springs and steel strips cooperating and in conjunction with the connecting mechanlsm give a general cushion effect to the seat. The loops 21 permit of a free lateral swayof the supports 11 occasioned by the rocking of the same in connection with the vertical sway of the steel strips'lO, unhindered by the uprights 19 passing through the same.

Having thus described my inventlon what I claim as new and useful and desire to secure by Letters-Patent, is,

A spring seat composed of horizontally arranged steel strips secured to supports un derneath the same and arranged at right angles therewith,'such supports provided with engaged by loops secured to such supports 10 bearings and being connected to each other in which loops such uprights have a lateral by means of adjustable rods provided With play. v heads at each end and springs engaging the In testimony whereof I aflix my signature same between the heads and the bearings in in presence of two Witnesses.
