THOMAS GRIMMITT, or ROCKFORD, ILLINOIS.

WAGON RUNNING-GEAR.

SPECIFICATION forming part of Letters Patent No. 545,491, dated September 3, 1895.

Application filed May 7,1894. Serial No. 510,418 (No model.)

To all whom it may concern.-

Be it known that I, THOMAS GRIMMITT, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Wagon Running-Gear, of which the following is a specification.

The object of this invention is to construct a running-gear for wagons, in which the front bolster has a limited pivotal movement at its center, in order that the ends of theaxle may have a vertical movement without disturbing the horizontal position of the bolster, which will support the front end of the wagon-box on the same horizontal level with'the rear portion, preventing the twisting'of the wagonbox.

The further object is to hold the tongue supported in a yielding manner and made vertically adjustable.

The further object is to form a pivotal connection between the frontbolster and axle in a vertical direction and aroller connection between the bolster and circle.

In the accompanying drawings, Figure 1 is a plan view of my improved running-gear. Fig. 2 is a lengthwise central section. Fig. 3 is a transverse vertical section through the front axle. Fig. 4 shows the various parts making up the front end of the reach. Fig. 5 is an isometrieal representation of the roller 19 and its bracket-support. Fig. 6 is an isometrical representation of the king-bolt.

The front axle 1 is fitted to receive wheels 2, and to its upper face are secured hounds 3, between which is located a tongue 4 and havin g a pivotal connection therewith. A circle 5 is supported by the axle and bounds 3, having its periphery bordered by a metallic band 6.

To the front face of the axle are secured vertically-perforated plates 7,between which is located the free end of a spring-bar 8, secured to the tongue, and a pin 9,'extending through the perforation of the plates above the free end of the spring, forms a connection between thespring and axle and serves to hold the tongue supported in a yielding manner, and can be held supported at different heights by placing the pin in the different holes in the plates '7.

To the upper face of the hounds, over the axle, is secured a sand-bar 10, and to its upper face, at its center, is secured a plate 11, being higher at its center and provided with a perforation coinciding with a vertical hole through the sand-bar and axle.

To the under face of the front bolster, at its center, is secured a plate 12, similar to the plate 11, secured to the axle, but in a reverse position, and has a vertical hole through its center coinciding with the hole in the plate 11. A king-bolt 13 has an enlarged upper end, being seated in a recess found in the under face of the front bolster, and through which passes a horizontal pin 14, serving to hold the bolt in connection with the bolster, the opening in the head portion of the king-bolt being of irregular shape, as shown at Fig. 6. This bolt is passed through the front axle, forming a connection between the bolster and axle.

To the under face of the front bolster are secured brackets (shown at Fig. 5) consisting of a base-plate 15, provided with an elongated opening 16 at one end and its other end provided with a lengthwise slot 17, and from the center portion of the base depend'perforated cars 18, between which is located a roller 19.

A bracket of the above construction is secured to each side of the bolster, so that the rollers 19 will overlie the metallic band 6 of the circle.

The front section of the reach 20 has a connection with the front axle by the king-bolt vertical opening 25, through which the kingbolt passes, and from its rear and front faces extend trunnions 26, which are held between the semicircular bushings 23 of the plates 21. With this bushing 24 in place in the end of the reach it is placed between the-sand-bar and front axle, and the king-bolt, passing through the parts, forms a connection between the front axle and reach. The outer faces of the plates 21 are slightly oval in order that the axle may have a rocking movement in its connection with the reach.

To the upper face of the front section of the reach is secured a bracket 27, having an upright portion 28, supporting rollers 29 and 30, the former located above the circle and the latter below it and in contact with the metallic edge strip 6, forming an antifriction connection between the axle and reach.

The rear portion of the running-gear is of the usual construction, the rear section 31 of the reach having an adjustable connection with the forward section by the plates 32, secured to each section having sides 33 embracing the other section, and a series of holes in each section, through which screws are passed, entering a screw-threaded opening in the base of the plates.

The forward bolster, having what may be termed a universal. connection with the forward axle, permits the axle turning about in a horizontal plane and its ends a vertical rocking movement without changing the position of the bolster, and as the forward end of the wagon-box is supported by the front bolster it 'will be held in the same plane as its rear portion.

Should the running-gear be employed to support a hay-rack, for instance, it will be necessary that the forward bolster be locked or held in contact with the axle so far as the vertical rocking movement of the axle is concerned. This is accomplished by loosening the brackets supporting the rollers 19, and turning them around so that the rollers will overlie the metallic edge of the circle and will turn in contact therewith, as shown in dotted lines, Fig. 3.

I claim as my invention- 1. In a wagon running gear, the combination of a front axle, a bolster having a pivotal connection with the axle through the medium of a king bolt, the king bolt having an opening extending transversely through its upper end and terminating in two branches, and a pin extending through the opening and through the bolster.

2. In a wagon running gear, the combination of a front axle and a reach having a connection therewith, the connection consisting of a bushing through which the king bolt passes and plates secured to the end of the reach supporting the bushing in a pivotal manner.

3. In a wagon running gear, the combination of a front axle, plates secured to the front face thereof, each provided with a vertical series of perforations, a tongue having a pivotal connection with the axle, a bar spring secured to the tongue having one end passing between the plates, its other end curved upward having a vertical opening through which a bolt passes holding the evenerto the tongue, and a pin located in the perforations over the end of the bar spring.
