UNITED "STATES SPECIFICATION 1b @ZZ whom it `may northern:

ne it known that I, HENRI ED'ELINE, eri-f gineer, of 108 Rue de la Reunion, Paris, in the Republic of France, have invented certain new and useful Improvements'in Struts or Rest-Bars for TwolVhcel Vehicles, of which the following is a specification.

This invention relates to a strut or rest-bar, the length of which can be varied, for twowheeled vehicles-such as carriages,tipcarts, tumbrils, dse-which strut will serve also as a third wheel. l i

The strut of the usual type presents serious inconveniences, for in order that it shall be eiiicacions it is necessary that it should have such a length that its lower end should be a -very'short distance from the ground, and

- animal..

under these conditions it happens that on Vbroken ground it is found too long, and consequently causes inconveniences. Again, it may .Wound the hind quarters of the draft- The strut which forms the object of `this invention is such that its length may be regulated, and this may be varied,according to the cha'racter of the ground over which the vehicle has to pass. Besides it may serve as a thirdwheel,l its lower end being lprovided with a wheel or roller which will roll on the ground,and thus provide a third point ddppu for the vehicle and avoid that the load shall Weigh too heavily on the draftanimal. The connection between the wheel and the fixed part of the strut is made by means 0I springs, which give a certain elasticity to the system when the carriage rests on its strut. In this manner the rolling of the Wheel on the inequalities of t-he ground does not cause shocks. This strutis represented in the annexed drawings, in which- Figure l is a sectional elevation. Fig. 2 is an elevation, partly in section and at right angles to Fig. 1. Fig. 3 shows on a reduced scale and in front elevation the4 application of the strut to a tip-cart looking from the front of the vehicle. Fig. et is a corresponding pian View, and Fig. 5 is a side elevation,

` of the tip-cart with the invention applied thereto. 1 v

'This apparatus is adapted -to the frame of the vehicle in any suitable position, according to the class of vehicle. For a tip-cart,

for instance, it is placed at the back of the t shafts, but in front of the axle,

connecting the shafts to the body.

The apparatus includes a tube or support A,

which is slotted at o and is fined to the crosspiece of the shafts and containing' a second tube or carrierB, provi'ded'with alug b2, which works in the slot,so that this tube Bis prevent-f1 ed from turning. To ahead or block bat the top end of this tubeB is attachedascrew C, which extends upward through `a nut D., to which a miter-wheel d is attached, the said miter-wheel (Z being driven by a pinionE, operated by the attendant by means of a handlefon the pinion-shaft F. (See Figs. 3 and 4.) A third tube G, to the lower end of which is pivoted at h in any convenient manner a caster or wheel frame H, carrying a wheel I, (crit may be a pivoted frame for two wheels,) is inclosed in the tube B, the said tube G containing a strong spring J, which has its abutment at one end at the bottom of the tube and at the top against the head b of the screw C, which head is provided with a guidedod b for the spring J. Thus the wheel-frame H elastically supported.

The tube G is formed with vertical slots g, in which engage lugs b3 on the tube B, an arrangement which assures the guiding of this A tube G in its vertical displacement and 'pre-f vents it from becoming disengaged from the tube B under the pressure ofthe spring J.

The tube A is held perfectly rigid by means of suitable stays A from the shafts and crosspiece or any other part of the vehicle.

The working of the apparatus is as follows: The attendant actuating the handle f, and thustnrning the geared. uut D d, regulates the maximum length of the strut computible with the nature of the ground on which. the

roller is to run. By tu ruing the geared nut D d so as tod rawthe tube B intothe tube A the'tube G will be raised by the lugs b3, which act on the upper part of the slots g,and the total maxi- -mum length of the strut will be diminished.

Inversely, by pushinglout the tube B from the' tube A the length will be increased.

In this manner, the length of the strut having been regulated for the wheel to roll on a good road, when the cart arrives at an uneven part of the road the attendant will diminish the length of the strut to any requiredexf the shafts.

tent. l On goodground the lstrut will rest onl the ground-by'its rollers or wheelsI and con stitntes a third wheel, which eases considerably the draft-animal, which is known as the shaft-horse. vBy reason of the'springs J the tube G, With its rollers, can be displaced vertically and automatically in-the tube B, according to the inequalities of the road, which gives-,an easy movement.

, This'apparatus su ppresses the employment of'rest-bars, seeing that the shafts will be supported'. When. the shaft-horse stumbles or falls, it Williind/itself suspended, and the action of thevsprings Will assist in raising it toitsfeet again. Further, when the vehicle -isftippe'd to discharge the contents the strut remains vertical and supports the Weight of These various characteristics of the apparatus giveconsiderable relief to the draft-animal. i v
