ment with respect to the reach, the connec-- tion being yieldable laterally and torsionally and so constructed that there will be no pivotbolts to wear loose and rattle and no twisting strain on the reach, as more fully hereinafter set forth.

- the vehicle body or box upon springs preferably rigidly connected at their upper ends'to the box and at theirlower ends to the axles, i

there being preferably but one spring, and that of a spiral form, in the middle of the front axle and as many as desirable of a spiral or otherformlonlthe rear axle, whereby the box' will'be'yieldingly supported and the front axle willibe'free to turn. and yield in all directions,tl1e. central front spring permitting this by reason' of its susceptibility to.

torsional and longitudinal strains, thereby entirely avoiding the use of the fifth-wheel and king-bolt and other connecting devices that mak'enoise and'wear and rattle, as more fully:hereinafter set forth.

In thedrawings annexed, Figure l omitted; Fig. 2, a plan view showing the connection between the reach and the axle, the vertical body-spring being shown in section; Fig. 3, a vertical, sectional view showing .the springs connecting the axle tothe box and to the reach; Fig. 4, detail views of the devices connectingthe spring vandthe reach; Figs. 5 and'6, detail views of a modified form of devices'conne'cting the spring and the reach.

This invention will be best understood by a detail description of the form of devices I prefer using.

Referring to the drawings by letters, a desfront end of the buggy-box and rigidly connected to the same at its upper end and at its lower end to the front axle about midway the ends of the latter, and b the spring or springs connecting the rear end of the box to the rear axle, this spring or springs being of a spiral form, as shown, or any other form desired. The buggy-box is unsupported except by these springs, whereby it may yield in all directions. The central front spring not only affords a resilient support for the buggy-box, but also affords a sort of universal connection between the same and the front axle, whereby the axle will be free to yield in all directions. It will be observed that this spring connection permits the axle to freely turn in either direction in turning the v buggy around, the spring yielding torsionally The invention further consists in mounting for this purpose. This peculiarly-arranged spring. also permits the'front axle to vibrate vertically'without communicating any jar to the buggy-box? As will .be observed, it entirely avoids the use of the king-bolt andfifthwh'eelor circle and'simil'ar connections between the axle and, the buggy-box, thereby avoiding all wear and noise and rattling of the parts, which, as is obvious, is 'of great advantage. The ends of the spring may of course be connect-ed in any suitable manner without departing fromv the spirit of my invention. In the drawings-the upper coil of the spring fits over a circularboss on a plate 0, and said plate is bolted to the bottom of the box by means ofbolts (I, said bolts pass .ing up through lateral earsd, formed in the is a side elevation i'ofia buggy provided with my'iniprovements, the wheels on one side being:

upper coil, andllthrough corresponding ears on the plate. The lower coil of the spring fits around a boss formed on the upper side of a clip e, bolted around the axle,'said coil being slightly smaller than the main coil of the spring and being held in place by a short bolt 6, passing down through a hole in the upper side of the clip and having its head elongated to engage over said coil, the nut on said bolt being inclosed in a recess under the upper plate or bar of the clip. The clip 6 is divided diagonally and clamped over the axle by-suitable bolts 6 The letter f designates a coil-spring connecting the front end of the reach to the front axle, and g a central connecting bar or link,

also connecting the front end of the reach to the axle and serving not only to take up the draft strain, but also to keep said spring compressed. The front coil of said spring fits around a boss formed on the rear side of the clip a and is clamped thereon by means of an eyebolt 71, whose extended head engages over said coil and whose threaded shank passes through an opening in the rear plate of the clip and terminates short of the axle, the nut on this shank lying out of the way in a recess between the rear side of the axle and the rear wall of the clip. The rear end of the spring fits around a boss on a plate 2', bolted to the front end of the reach, being fastened thereto by a pair of bolts j, which pass through oppositely-projccting ears 7.7, formed on the end coil of the spring, and through corresponding ears on the plate t and the iron i on the reach. An eyebolt Z is threaded and riveted into a nut Z, which rests in a square central recess in plate i and is clamped to the reach by said plate, the four reduced corners of said nut resting in recesses in the inner face of said plate 1', the nut being there by held against withdrawal from the plate. 111 attaching the spring to the reach the spring is first compressed to the desired tension by means of a vise or other suitable instrument, the forward end of the spring having been first attached to the clip and the plate ihaving been placed in the rear end of the spring. As the spring is compressed the rigid nut Z will be passed through the central square opening in the plate 'i and said plate will be given a quarter-turn, so that the shoulders on the corners of the nut will come opposite the recesses in the rear side of said plate. lVhen the compression of the spring is eased up, said corners of the nut will enter said recesscs, and thereby lock the nut and the plate together, holding the spring in its compressed condition. It will be observed that the link or the rod g loosely connects the eyebolts and is free to swing in any direction.

It is obvious that anyothersuitable device may be employed for connecting the ends of the spring respectively to the clip and the reach. For instance, the devices shown in Figs. 5 and 6 may be employed. In this arrangement the reachiron is provided with a central opening for the passage of the threaded shank of an eyebolt m, whose elongated head engages over the rear coil m of the springfand clamps the same around a boss formed on said reach-iron. To permit the eyebolt m to be inserted into the coil m and turned quarter aroun d to extend over the coil, said coil is elongated, as shown in Fig. 6. The boss on the reach-iron is shaped so that the elongated coil will [it around it. This peculiar manner of attaching the reach to the axle has a number of importantadvantages. It will be observed that the draft strain is taken up by the endwise unyielding pivotal connection inclosed in the spring and that the expansive force of the spring takes up all the wear in the joints of said connection and prevents the same making noise and rattling however worn the joints may be. tion allow of a practically universal movement, permitting the front axle and the reach to yieldlaterallyindependently of each other. As is obvious, the axle will be permitted to rock or oscillate vertically when one of the front wheels passes over an obstruction without twisting or straining the body or reach, the spring taking up the torsional strain, thereby avoiding a very serious objection to the ordinary manner of attaching the reach to the axle. The draft strain will come upon the link connection and the backing strain will be divided between the spring and said link connection, the spring taking up most of this latter strain, its coils being pressed quite closely together for this purpose and for the further purpose of affording a lirm connection between the reach and the axle and keeping the desired tension upon the connecting-link.

I have shown but one spring connecting the body to the front axle and but one connecting said axle to the reach. It is obvious, however, that two or more springs maybe employed in heavier vehicles. \Vhere two or more springs are employed, they should be placed side by side, so that they will afford practically as free a movement of the front axle as the single springs. It will also be obvious that the connecting-link 1 may be omitted in light vehicles; but in that case the spring will be somewhat heavier and will not be compressed. It is likely, however, that in all cases a connection of some sort will be advisable to keep the spring compressed and take up the draft strain. Any suitable swinging connection may be employed instead of the rod shown, as the main function of that rodis to take the draft strain and keep the spring compressed.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. Inavehicle, the combination of the axles and wheels and body, suitable means for supporting the body on the rear axle, and a coilspring supporting the front end of the body on the front axle, said spring being connected at its respective ends to the axle and to the body whereby the spring may yield vertically and torsionally, as and for the purposes set forth.
