SPRING-SEAT.

SPECIFICATION forming part of Letters Patent No. 783,489, dated February 28, 1905. Application filed January 4, 1904- Serial No. 187,607.

To all whom it may concern.-

Be it known that I, JOHN WERNER, a citi zen of the United States, residing at the city of Dubuque, in the county of Dubuque and State of Iowa, have invented new and useful Improvements in Spring-Seats, of which the following is a specification.

My invention relates to spring-seats for wagons, with special reference to those used on lumber or heavy wagons; and one of the objects is to provide a seat which shall be exceedingly elastic, cheaply constructed, strong and serviceable, and which can be readily attached to and detached from a wagon-box and adjusted to wagon-boxes of different widths.

A further object is to provide means for preventing the seat from becoming disengaged from the wagon-box, caused by the attendant jar or otherwise connected with this class of wagons, and to quickly and securely lock the seat on the box.

It consists of a seat to each end of which is attached one part of a divided spring. The other part of the spring is attached to the Wagonbox; and it also consists in a lock for locking the seat on the wagon-box.

The manner in which the objects herein sought are accomplished is fully set out in the following specification when taken with the drawings accompanying the same and forming a part hereof.

Figure 1 is a perspective view of the seat in position and locked on the wagon-box. Fig. 2 is a side view showing the seat locked to the wagon-box. Fig. 3 is aperspective view of a portion of one side of a wagon-box and ahook and locking device unlocked. Fig. 4 is a perspective view of one of the springs removed and showing part of the means for adj ustabl y attaching the spring to the seat. Fig. 5 is a side view of the spring removed. Fig. 6 is a perspective view of one part of one of the looking devices. Fig. 7 shows another part of the locking devices. Fig. 8 is a view of the under side of the seat and one spring, showing means for the adjustable attachment of the spring to the seat.

Like letters of reference denote corresponding parts in each of the drawings.

Referring to the drawings, A. designates the seat; B, the back; 1), the base, and E the stays. It is'not essential that there be a back to the seat, but simply a base 1).

The spring G- consists of a plate of spring material partially divided longitudinally along in its center at H, and at the ends of the division small circular openings .1 are also formed. After the plate is thus split one part, K, is bent downward, and the other half, M, is bent upward, forming practically two springs K and M, united together and adapted to operate in opposite directions and in parallel planes.

It will be observed that the bends in the parts M and K of the spring Gr do not commence at the openings 1, but a shortspace O nearer the center, and in that space the two parts M and K remain in the same horizontal plane. By means of this construction there is given greater elasticity to the springs or parts M and K.

For the purpose of better staying and strengthening the spring G the ends N of the spring may be bent or curved downward at it or the ends bent over and clasped around a pin L, as shown at one end in Fig. 5. The part M of the spring thus formed is attached to the under side of the base 1) of the seat. For a convenient mode of attaching the spring or part M to the seat there is provided a tenon Lon one side of the spring, and on the bottom of the seat is a loop or socketf', in which the tenon bengages and adjustably secures the seat to the spring. It will be seen by this mode of construction the same seat and springs can be adapted to wagon-boxes varying in width and size. The other part, K, of the spring is provided with hooks, presently to be described, by which said part is adapted to be removably attached to the wagon-box.

For the purpose of readily and conveniently attaching the springs to and detaching them from the wagon-box there is secured to the part K hooks or loops P, which project upward and are bent to conform to the shape of the upper edge of the wagon-box and extend down a short space on the opposite side of the box. These loops 1 are provided on their lower edges with catches R for the purpose presently to appear. Against the outer side of the box S and directly beneath each loop P is fastened a plate 1, preferably of spring metal, in which is formed a spring-tongue V, provided with a projection d and loops or hinges a, with a rod g passing through the hinge e. To this rod 9 is also hinged a lockplate consisting of a thin strip of metal provided with loops Z, through which the rod passes, to hinge the plate IV to the plate T. The plate 7 extends down at i to a plane parallel with the loops in, and the projection (Z of the tongue V projects up betweenthe loops 7c. By this mode of construction it will be seen that the spring tongue will press against the end i of the plate IV and hold it in engagement with the catches R on the loops P and in this manner lock the two together, and when unlocked, as shown in Fig. 3, will press against the back side of '11 and hold the plate \V open.

The manner of using my device is substantially as follows: The width of the wagon-box is first determined, and then the tenons b of the springs are inserted in the loops f and adjusted to the width of the wagon-box. The loops P are brought into engagement with the upper edge of the wagon-box and the plate IV brought up into engagement with the catches R of the loops P and are held in such engagement by the spring-tongue V pressing against the plate In this manner the seat is securely locked to the wagon-box.

It is manifest that different details of construction may be employed without departing from the spirit of my invention.

Having now described my invention, what I claim is 1. In a device of the character described, a seat, a spring for each end of the seat each spring consisting of a plate partially divided and the two parts set to operate in parallel planes, means for attaching one part of the springs to the seat, means secured to the other part of the springs for attaching them to the wagon, and a lock for locking them on the wagon.

2. In a device of the character described, the combination of a seat, a spring for each end of the seat each spring consisting of aplate of elastic material partially divided longitudinally and the parts set to act in opposite directions and in parallel planes, means consisting of a loop secured to each end of the seat,

a tenon secured to one part of each spring and adapted to ad justably engage the loop on the seat, and means secured to the other part of the spring for removably attaching the same to the wagon.

3. In a device of the character described, a seat, a spring at each end of the seat each spring formed of a strip of elastic material partially divided longitudinally and forming a double spring and set to act in parallel planes, means for attaching one of the parts to the seat, a hook attached to the other part and adapted to removably engage the upper edge of the wagon-box, and a lock engaging the hooks for locking the seat upon the wagonbox.

4. In a device of the character described, a wagon-seat, a spring at each end of the seat each spring consisting of a strip of elastic material partially divided longitudinally and bent to form two springs adapted to act in opposite directions and in parallel planes, means for attaching one part to the seat, a hook secured to the other part of the spring and adapted to engage the wagon-box, projections on said hook, a lock for locking the seat upon the wagon consisting of a plate secured to the side of the box, a hook-plate hinged to said.

plate on the box and adapted to engage the catches on the hooks and secure the hooks on the wagon-box.

5. In a device of the character described, a spring-seat for wagons consisting of a seat, a spring for each end of the seat formed of a sheet-metal plate partially divided longitudinally and the parts adapted to operate in parallel planes, means for staying the springs by curving their ends, means for adj ustably attaching the seat to the springs, a hook secured to one part of each of the springs and provided with projections upon the ends of the hooks, and means attached to the sides of the wagon-box and engaging the projections on the hooks for locking the seat on the wagonbox. v

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

JOHN WERNER.
