BOLSTER-SPRING.

SPECIFICATION forming part of Letters Patent No. 524,365, dated August 14,1894. Application iiled April 28, 1891. Renewed Apn'l 27, 1894:. Serial No. 509,202. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM H. WEBER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bolster-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to thevletters of reference, marked thereon, which form a part of this specication.

rllhis invention relates to wagon bolster sprlngs, and more particularly to means for connecting said springs with the bolster, and has for its object, among other things, to render the connection between the springs and bolster more efficient and durable, and at the same time easier to assemble and disconnect, and to provide a free movement of the springs by reason of the connection mentioned.

It also has for a further object to combine the stake supporting and bolster-spring securing devices in order to simplify and strengthen the structure. f

To these ends my invention consists in certain novel features which I will now proceed to describe and will then particularly point In the accompanying drawings: Figure 1 is a perspective view of a structure embodying my invention; and Fig. 2 isa transverse vertical sectional view thereof, partly in elevation; the section being taken through the middle of the stake.I

As shown,-A represents the bolster, and B one of the semi-elliptical springs to be connected therewith. I n practice there'are two of these springs employed, oneY on each side of the bolster, and `connected with said bolster at each end thereof, but in the drawings only one end of the bolster and of one spring is show n, as this is all that is necessary for a proper comprehension of my invention, it

4 being understood that the connection at both sides and at both ends of the bolster is the same as that shown.

C represents a wooden stake which is tenoned into the bolster in the usual vmanner. This stake is braced or reinforced by supports, one on each side of said stake and each consisting of a base C resting on the bolster,

an upward extension or strap Clin contact with the side of the stake, and a iiange C3 extending downward over the upper edge ofthe bolster. The upward extensions O2 of these .supports are secured together in any suitable manner, as by rivets c which pass through the stake, while the flanges()8 embrace the upper part of` the bolster and are connected by a bolt c passing not only through the bolster but through the stake tenon as well, as shown in Fig. 2.

D represents pivot pins cast integral with, or rigidly secured to, the base C of the stake supports. These pins extend laterally outward on each side of the bolster, de. to the front and rear, and their ends are preferably reduced and are threaded to receive nuts CZ. Upon each pivot pin is mounted a shackle E composed ofa sleeve portion e which tits the pivot pin D, and depending arms e at each end of said sleeve portion, said arms e being apertured at their lower ends to Vreceive a pivot-bolt F provided with a nut f. The end of the spring B is formed intov or provided with a sleeve b which is adapted to it 4between the depending arms e of the shackle E, andthe pivot bolt F passes through the said sleeve b as well as through, the arms e', thereby uniting the shackle and springs. The pivot pins D are also each provided with a shoulder d between` which and the nut d the shackle is so held as to prevent excessive end movement of the shacklebn the pin.

It will be noted that 'with this construction either spring may bereadily disconnected from its shackle, or either shackle from its pivot pin, and as easily replaced. It will also be observed that the shackles have firm, vsmooth and durable bearings on the 'pivot pins which serve to effectually support said shackles. Moreover, the pivot pins being secured to the stake supportsa simple, compact, efficient and economical construction in the parts is thus provided,

l. The combination with a bolster and stake, of a two-part vsupport for said stake secured to said bolster, one-parten each side of the stake, pivot pins rigidly secured to said supports, shackles pivotally mounted on IOO ,bolster and stake tenon, a xed pivot pin rigidly connected with each base, a shackle pivoted on each pin, and bolster springs pivotally connected with said shackles, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

WILLIAM H. WEBER.
