IMPROVEMENT IN MOTIVE POWER FOR CARRIAG-ES.

The Schedule referred tain these Letters Patent and making part of *the same derstand and use the same, reference being had to the accompanying drawings making part of' this speci-f lication. o

'lhe figure is a. side view .ofv the device illustrating my invention, partly in section and applied to a car. My invent-ion consists in a motive power intended to he applied to cars,carriages, andv vehicles generally, and is derived from a series of' arms having elastic feet,

' and made to revolve so as to take hold ofthe ground,

the bed -ofa road, or any foundation especially laid therefor, and thereby propel the conveyaiice with great rapidity, safety, and surety.

ln the drawings- A may represent a vcar, carriage, or conveyance of any sort.

In thc present case I, have represented a car having one of its platforms extended so as to support 'its lvm'lt'ing-parts, which form the propelling power.`

l From the platform there arisesstalulanl a o., which form the bearings of the shaft to which the fly-wheel b is secured.

A series of gearing, c, is connected with the Hywheel iu order to communicate motion to a wheel or `hub A', which is secured to a shaft properly mounted on arms or standard rising from the platfbrm.

'lo this hub or wheel there aresecured arms 'l B, \\`hich.radiate t-l1erefiom,-and may be'construeted of wood or metal, either flat, round, or tubular, in the f'orm of' a curve or right lille, and of any number, thickness,vand length, suitable for the purpose. intended.

The hub and arms 4thus produce an'anned wheel A" B. I To cach of the outer ends of the arms is fixed an elastic foot, C.

In the 'present case these feet consist of pieces of` rubber, I), rigidly connected to tubes E, which are made to slide over the arms B, or the latter may slide over the former.

A slot, d, and pin,- c are respectively formed wit-h each tube audarm,`to `limit the play of the foot, the pi n being adjustal'ile therefor.

Elastic springs maybe interposed between the tubes and arms in order to throw ont the former, although this can be accomplished bythe rubbers D, which may project suflicientl y into the tubes so as to be compressed when the feet are forced towardthe center.

The arm B, could be made of'l elastic material, and thereby' dispense with the interposed springs.

The operation is as follows:

Power of' any kind is to be applied to the flywheel" b or. elsewhere, to cause rotation of' the ar'ms B B. If hand-power is employed, a crank should be connected to the fly-wheel or its shaft.

0n rotating 'the arms the feet reach the ground or bed, or foundation of the road, and take hold thereof, and consequently connnunicate motion to the car or .conveyance A.

It will be seen that the distance from the axis of' the arms and feet to their extreme ends is greater than that from the axis to the ground or bed, 'consequently the arms and legs could not pass the center were it not that the feet are elastic, and thus give.

The momentum of' the conveyance and power derived from .the fly-wheel and gearing will assist the arms and. legs in their operation, and thus render the device easy of manipulation, and produce a rapidity 'of' propulsion and strong power.

,lhe liub A maybe dispensed with, and the arms B be secured directly to its shaft, but itis preferable to use the hub in view of the strain on the arms, whereby the connection between the arms and shaft must be made extremelyqstrong, and this is accomplished when the hub is employed. l l

It is n'otnecessary that the aforesaid devi'ce be particularly located on the front o r rear plat-form of a vehicle, as it is equally applicable to the sides thereof. In the lat-ter case an armed wheel is placed on each side, both having the same shaft and a single fly-wheel and set of gearing arranged on said shaft.

In some cases rubbers I) may be applied directly to ytheends of the arms. In either case said rubbers takeiii-rn hold 'of' the ground, bed, o r foundation, to assist in propellingr the vehicle, and likewise'prevent slipping ofthe arms. l

rlhe device tln1s `specilied is simple, practical, and

useful.

Having thus described my invention,

What I claim as new, and desire to secure by Let, ters Patent, is

1. The series of rotating armsB B, operated by suitable mechanism and power, and applied to a ve-v hicle to operate, substantially as set forth.

2. The rubber' I), applied to the armed wheel A ,13,-s0 .as to come in contact with the ground or road, substantially as and for the purposes described.

lhe rotating arms Ii, carrying elastic feet C, substantially as and for the purposes described.

The above signed by me this 8th day of liebruary, 1870.` "i
