Be it known that I, LEWIS F. Huts, of Salem, Columbianapounty, btat of Ohio, have inventedcertain news ind useful Improvements in Steam Land conveyances; and I do hereby declare that the following is a full clear, and exact description thereof, reference being had to the accompanyingdrawing s. making -a mm of this specification, in whichi Figure 1 is a plan view of the steam land conveyance.

' The main object of my inventioais to so construct a steam carriage for common roadsthat the entire framework and the driving machinery, togetherwith the engine and boiler, can be mounted upon springs, and motion v communicated to the h-anspoiting-wheels by means of flexible or compensating connections, thereby Iireyentiu g injurious jars. and shocks being communicated to said machinery, and affording an easy-running carriage, as will be hereinafter described.

, Another object of my invention guiding the machine, as will be hereinafter described.

In the accompanying drawings, A represents a rectangular frame, which is supported'at its rentend upon two semi-elliptic springs a a, the lower one, a, of which isconnected by links to two goose-necks that are a secured to bearings through which the axle B passes. The forward portions of said gooseuiecks are'prolonged 3 which are secured to the sidesof framc A,"near the middle of its. length with said pendants, The forward end of I said frame A is supported by means of springs, b b binndn, upon the o longitudinal springs c cextcnd across the 11:10.0, and are These two springs have attached to theirends the two bolted .-to hearings through which this axle passes. diagonal springs b b, and transverse spring b", and secured. A king-bolt, L

tothe two diagonal springs the transverse spring c'is allow this axle to betui'ned tothe right or left for guiding the carriage. In or'derto l:

al rods, e e, which rods have their hearings on the front side of the transverse frame a person upon the frame Acan-turn them and, thus more t turn it around. The trnnsrerscframe D consists of two transverse bars wh ants a, and adaptcd to serve as hearings for three large spur-wheels, ff f, and also for a pinionspur-wheel, g, which latter has its bearings sufiiciently elevated for it to engage with the two wheels ff, as shown in fig. 1. The shafts it h, of the two spur-w on the rear ends of these shafts I large 'ber'el'spnr-wheels E E, on the axle B, as shown infig. 1. By these means the turn said axle andwith it the. rear driving-wheels F F, when these wheels are clutched to, their axle, and while is a horizontal sectional view of the front part of the carriage, showing the mode of melting isto provide for making the forward guide-wheels as wellas the rear wheels driving-wheels, the same time to allow of a free movement being communicated to the shaft of said wheels in ,passcs vertically through the transverse spring, 0, and through a transverse spring, c,

which is secured to the frame 'A, and thus connects the front axle G to this frame by a pivot joint, which will ecp the rule 0, in its,

g and to steady the spring frame which is interposed between it and the frame A, Iemploy a segment, G, which is' sccured at its ends to the reai cnds of the longitudinal springs c a, so as to be concentric ll allow the segment to slide freely through it either to the right or any lvgelsff, have universal or gimbal joints, 1' 1", applied to their extremities, and hiln' nc el pinion spur-wheels jj are keyed, which-engage with the teeth of wheels f'f are csusedto 1 forreceiv ing the clutch-plates a t, substantially sa described.

new V2 this is the case the jointed shafts h It will, by their flexure, allow freedom of motion to the frame A, without causing any strain or binding of the shaft at its joints. The central or intermediate spur-wheel f communicates motion to the bevel spur-wheel k, whicli has its hearings in the centre of a transverse bar, In, by means of an extensible shaft, G,- which is also provided with gimbal or universal joints, 2' i. This bevel-wheelie engages with the teeth of a-large bevel-wheel, E wliiolr-is keyedto thomiddlo of the length of thefrontaxle C, and transmits motion from the wheel 1" to I this agile in whdtevon position this a'xle may be adjusted. The shaft G is made extensible, so that it will accommodate itself to the obliquity given to the front axle C, in guiding the I machine. The gimbal joints 1' serve the same purpose on the shaft G as the gimbsljoints on the rear drivingshafts h h. The short shaft of the pinion driving-wheel g carries on one end a balance-wheel, H, and on the other end a crank-wheel, I, to the face of'gwhich latter a pitman-rod, J, is connected which receives its motion from the cross-head J} of an engine, J "This engine is suitably secured to thecarrisgc frame and driven by means of steam which is generated in an uprightboile'r, K, located near therear end of frame A, and suitably supported thereby. The steam pipe L, which forms a. communication between the steam chestof the engine and the boiler,

may be made flexible, so that the jars and concussions in travelling over rough roads-shall not open the joints and allow steam to escape. The transporting-wheels F F, which are applied to the forward'ahd rear axles B and C, are constructed with smooth-surfaced felloes, which are perforated to receive throughthem a number of radial rods,'l l, which are applied to knuckle joints mm that are pivoted to the circumference of two sliding collars, n 1 upon the hubs of the wheels. The inner collarsm are constructed with annular grooves in their peripheries, in which rings or yokes, r, are fitted loosely, as shown in figs. 3 and 4. These rings 1) have yoked levers, M, pivoted to them, which levers are pivoted to vibrating arms M in such manner that the two collars n can be moved upl to or from the collars p at pleasure. When the collars n are moved toward the collars p,

the knuckle joints m m will project the ends of allthe rods 1 l beyond the circumference of their respective wheels,- as shown in fig. 4, thus enabling these wheels to hold firmly to the surface of the ground'in rolling over it. The inner ends of the hubs of the wheels F F are chambered forreeeiving within thennthe clutch plates s r, by which said wheels can be afliaed to or made loose upon their shafts at pleasure y In the accompanying drawingul have only represented one of the transporting-wheels adapted for a traction-wheel, but in practice both frontiaud rear wheels will have the extensible rods 1 I applied to them, as describedabove The mode of communicating motion to the guide-wheels from the engine, ivhich I have above described, enables-me to make these'guide wheels driving-wheels, and torotate their axle at all times without having the driving-gear work hard. The entire machinery which is used-to move the carriage can be properly housed in so as not to be exposed to injury, and the guiding apparatus as well as the levers for. operating the traction-spurs can be arranged so that it can be worked fromthe top of the carriage by the person-who rides thereon. The frame A may be constructed of wood or metal, and whileI prefer to mount it upon its forward and-rear axles, as I have herein shown 'and described, still, the supporting springs may be differently arranged wiphout changing the principle of my livention. I

Having thus described my invention, what I claim as new, anddesire to seeureby Letters Patents, is-.

1. In combination with the frame of a land conveyance, which is mounted upon springs and adapted for' sustaining the motive power and driving-gear, claim the use of gimbal-j'ointed shafts for transmitting motion to the axles of the transporting-wheels, substantially as described.

2. The use of the glmbal-j'ointed and extensible shaft G. for communicating motion to thc-forward axle of the guiding wheels, substantially as described. I

3. Supporting the forward part of the frame A upon the guidingaxle by means of springs, when said axle is sustained in part by a sliding segment, and operated by means substantially as described.

4. The arrangement of tlicjointed driving-shafts G, h h. beneath the spring frame A, substantially as described. v

5. The application of extensibl'erods l l to-the transporting-wheels of a land conveyance, said rods being 7,

so applied: that they can be made to protrude beyond the circumference of-.tho wheels or. drum within the same at pleasure, substantially as described;

6. Constructing the inner ends of the hubs of the transporting-wheels with recesses which. are adapted LEWIS F. min Witnesses:
