IMPROVEMENT 1N STEAM-casamos.

@In Srlgcmle reuma it in tigen rttcrs intent :no making part stikt' same.

TO ALL WHOM IT MAYACONCERNz p Be it known that we, Zancc P. Droemer: and IsAAc Gasse, of Newark, in thecountyot Essex, and State of New Jersey, have. invented a newandzuseful Improveinent in Locomotive-Apparatus; and fue do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the annexed drawings, making part oi' this specication, in which- Figure 1A is a perspective view,

Figure 2 is a plan, and

Figure 3 a front elevation of the walking-mechanism.-

'lhe same letters in all the iigures indicate identical parts.

This` invention 'consists in connecting a steam-engine or other motor to a system of levers, which, inimitation of the action of the legs of a man, by the reciprocziting motion of the piston, are made to walk over the ground, and dra'w a vehicle attached thereto. I

In the annexed drawings, A is a boiler, constructed as shown, to resemble' 'in form the outlines of the human body. Thehoiler is one of that class in which the fire-box is in the centre, and the waterjacket around the same. It is unnecessary tov describe this part ofthemechanism, as there is nothing peculiar in it. B is a steam-engine, of Awhich the pston-rod`0 is attached to a ptman, D, which drives the double crank E. Any motor may be applied to this crank instead of the steam-engine. A coiled spring, with clockfworlgmay be used 4to drive a toy machine constructed on the same principle. The cranks communicate a reciprocating motion to the connecting-rods F F, Vwhich are attached to the arms G G of two bell-crank levers, of which the arms G' G represent the thigh-bones of a man. 'There are two of these hell-crank levers attached to one'eenneetingrod, forming one thigh. They ar-e pivoted to a'rod, which passes-through hangers attached to the base of the boiler. The lower end of the arms G G are pivoted upon transverse rods, forming the knees, to which reds are also pivoted two reds, H, which forro the lower part of each leg. These rods are lpivoted-to lugs on the l pieces I I, which form the feet, at points represented' by the ankle of a man. The vertical oscillation of the arms G G will cause the legs tooscillate backwards and forwards, and as the cranks E are set opposite to enc another, the legs will be alternately operated in different directions, just as the legs of a. man move alternately in walking. Arms K K are attached to the rods, to which the bell-cranks are pivoted. These arms have slots in their lower ends to receiver. set-screw, passing through slots in the upper ends of the rods L L. AThe latter rods'are placed between the arms G' G', and are attached by pivots to the rods M, which, extending-above the knee-joints, have slots, through which -the 'pivot forming the knee-joints of the arms G and rods H passes. This rod, extending downwards, is pivoted to lugs at the heel of the foot-pieces I I, as clearly shown ing-L s the rods L l'J are attached to the arms K Kl, and as the latter Aare inclined in front of-the arms G G,and

as the two sets. of rods turn, therefore,'upon di'erent centres, the foot is turned down at the toeas one leg falls behind the other, and the knee bent, so that as the foot is thrown forward, it is raised by bending the knee, to step over any obstacle, the foot being turned downwards at the toe before being placed on the ground. This action may he increased hymoving the setserew', by which the rod Lis attached' to the arm K, nearer tc the .lower end of the slot in the latter. The length of the step .is controlled by the lever N, held in any required. position by a pin passing into a hole in the are O.. T'his lever is attached to two eonncetingrods, P'P, attached te rods Q Q, which, being pivoted on the knee-rod, extend-below it, and are bifureated at the lower en'd at Q), said bifurcations pressing against the front of the-rods H H. Elastic bands, R R, are passed around the rods Q, Il, and M, below the knee, n nd immediately.above the bifurcations Q. Insteadvof this spring, a spring like that shown in dotted lines may he used. The machine 'must be supported by a frame, running on wheels` have shown it attached to a cart. The front part of the shafts U is made circular, and the body is attached thereto by eyes, so that it may he turned by cords S, attached to a tiiler, T, The driver may, by means of the tilier, turn the machine as may be desired. This cart can be used on smooth ground; for rougher ground, lateral supports of wider hase may be necessary, or the boiler may be changedv in position, so as to lower the een'tre of gravity'. The purpose of the spring R is tti-straighten the leg, when th'e foot has been drawn haelt' in passing an obstacle.

A .l'bo reverse movement of the apparatus is regulated by the same lever, N, by xylrielithe length of the steps il regulated. When the lever is in the A{irst hole of the arc 0, as shown in fig. 1, tlio machine will make its longest steps; when n tbe second holo, tbe steps will be shertenetlyn the third or middle hole, it will not step;

in the fourth hole, it will move backward with abort steps; in the` liftlr hole, it:` will move backwards with long steps. Y Y

' Having .fully explained the construction und mode of operating this apporatus, what we eloim'ns ourinven tion, und desiro'to secure by Letters Patent, is-

.1. The combination of the crankl E, connecting-rods E, boli-crank lovers G G', and rods H H, the sniilports being arranged to-produco an alternately-stepping motion, substantially as described.

2. The combination of tbe-rods G G and H H )vitll the rods L L and M M, and foot-pieces I l', substantially as described. f v

3. The combination of the rods II H n'nd Q Q', substantially as ond for tbepurposc set forth.

4. The foot-piece I, pivotegi to the rods H eentrolly, end at the heel to the rod M, when said rols are so actuated us to cause an oscillating motion of the foot, substantially as 4amd for tbc purpose set forth.

5. The combination 'of the lever N, rods P und Q, with tbe rods G and H, substantially as and for the 6. The arrangement of the circular support U to the machines, und the `cordsS nml tillcr'T, substantially as set forth. i

In testimony whereof, wo have signed our names to this specification in the presence of two subscribing witnesses. i.
