SPRING-SEAT.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 18, 1905. Serial No. 246,277.

To all whom, it may concern.-

Be it known that I, SAMUEL PEPPLE, a citizen of the United States, residing at Smithville, in the county of Bastrop and State of Texas, have invented new and useful Improvements in Spring-Seats, of which the folowing is a specification.

My invention relates 'to new and useful improvements in spring-seats for wagons, automobiles, locomotives, and large and cumbersome vehicles where considerable jolting is produced. Y

The object of the invention is to provide a spring-seat which is prevented from moving laterally and the parts of which are so arranged as to produce an easy upward and downward movement of the seat.

A further object is to provide spring mechanism of simple construction Which may be readily repaired and which is of compact form.

With the above and other objects in view the invention consists of a series of hinged leaves which are secured between the seat and its base and are held normally drawn toward each other, so as to hold the seat removed from the base.

The invention also consists of equalizing devices which are connected to the hinged leaves and which revent one edge of the seat from tilting too ar in relation to the opposite edge.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a side elevation of the springseat. Fig. 2 is a similar view thereof with the side spring removed. Fig. 3 is a central longitudinal section through the seat. Fig. 4 is a front elevation of the seat. Fig. 5 is a section on line 5 5, Fig. 3; and Fig. 6 is a bottom plan View of the equalizing devices.

Referring to the figures by numerals of reference, 1 is the base, to the upper face of which are secured series of oppositelyarranged pairs of leaves 2, the leaves of each pair being hinged together and two of these oppositely-disposed pairs being located adj acent each corner of the base. The end leaves 2 are pivoted upon the cross rods 3, which extend across the front and rear, respectively, of the seat and are connected, by means of coiled springs 4, with the pivots 5 of the inner pairs of leaves 2. Long coiled springs 6 also connect the ends of the rods 3 and extend along the sides of the seat. These springs 6, as well as the springs 4 before referred to,

'serve to hold the pivots of the leaves 2 normally drawn toward each other, and therefore the seat 7, which is secured to the upper endsof the leaves 2, is normally removed from the base 1. Equalizing-bars 8 extend inward from the cross-rods 3 and are slidably mounted in guide-strips 9, which are secured to the pivots 5, before referred to. These equalizing-bars are slidably mounted within the guide-strips 9 and are inclosed by coiled springs 10 and 11. The springs 10 are arranged on the equalizing-bars between the guide-strips 9, while the springs 11 are located on said bars between the guide-strips and lugs 12 and 13, which are formed upon the equalizing-bars at opposite sides of the two guidestrips.

When downward pressure is produced upon the seat 7, either by reason of a weight placed thereon or the sudden j olting of the seat, the leaves 2 of each pair will swing toward each other, and therefore the distances between.

the pivots of every two pairs will increase and the springs 4 connecting said pivots will be tensioned. The two rods 3 W111 also be pressed apart, thereby tensioning the springs 6. In addition to this action the intermediate springs 10 and the end springs 11 will will be returned to its normal position auto matically by the various springs of the device. This return movement will be regulated, however, by the inner springs 11 on the equalizing-bars 8to wit, those springs contacting with the lugs 13. x

The same number of springs are employed for all sizes of seats, and itwill thus be seen that an extremely simple and inexpensive spring-seat is produced and that all of the parts thereof are readily accessible and can be quickly repaired or replaced. If desired, the seat can be regulated soas to operate more readily by removing the side springs 6 or, if preferred, by securing one end of each of said springs to the base 1, so as to exert a tension upon one pair of leaves 2.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware,that

modifications may be made therein without respective pairs, said means being arranged intermediate the ends of the seat.

2. The combination with a base, and a seat; of leaves hinged to the base and seat and to each other, rods forming pivots for the end leaves, coiled springs connecting said rods, andaoiled springs connecting the pivots of the adjoining pairs of leaves.

3. The combination with a base, and a seat; of leaves hinged thereto in pairs, said leaves being pivoted together, rods forming pivots of the end leaves, coiled springs connecting the rods, equalizing-bars extending inwardly from the cross-rods, guide-strips eX- tending from the pivots of-the inner pairs of leaves and inclosing the equalizing-bars, and

springs upon the bars for controlling the movement thereof.

4. The combination with a base, and a seat; of leaves hinged thereto and to each other to form pairs which are oppositely arranged alternately, coiled springs connecting the pivots of every two adjoining pairs, crossrods forming pivots of the end pairs of leaves, equalizing-bars extending inwardly therefrom, guide-rods forming the pivots of the inner pairs of leaves and inclosing the equalizing-bars, stops upon said bars, and coiled springs upon the bars and interposed between the guide-bars and the lugs.

5. A seat-support comprising a plurality of pivoted members arranged in similar pairs at opposite ends of the seat, means for con nectmg the remote members of each pair, and means for connecting the contiguous member of each pair.

In testimony whereof I affix my, signature in presence of two witnesses.
