MOTOR-PROPELLED' VEHICLE.

SPECIFICATION forming part of Letters Patent No. 568,431, dated September 29, 1896.

Application filed March 16, 1896.

To all whom it may concern.-

Be it known that 1, CHARLES DELAHUNT, a citizen of the United States, residing at Olathe, in the county of Johnson and State of Kansas, have invented certain new and useful Improvements in Motor-Propelled Vehicles; and I do hereby declare that the followin gis a full, clear, and exact-description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The objects of my invention are, first, to provide for the end bearings of separate vehicle and motor supporting platforms, employed conjointly; second, to exclude dust, chaff, &c., from the motor; third, to reverse the movement of the traction-wheels and change the direction of movement of the vehicle, and, fourth, to throw in and out of gear the driving-shaft of the motor and the reversing-gear to the traction-wheels.

My invention consists in the novel construction and combination of parts, such as will first be fully described, and specifically pointed out in the claims. v

In the drawings, Figure 1 is a plan view of the combined motor-carrying and auxiliary Vehicles. Fig. 2 is a longitudinal side elevation of the combined motor-carrying and auxiliary vehicles carrying the reversing-gear to the traction-wheels, and for communicatin g power from the driving-shaft of the motor to the traction-wheels, and for throwing the same in and out of gear; also showing the truss supporting the platform and the worm-gear operating the forward axle of the combined vehicles, the threshing-cylinder, the gasolene-tank, and the conductors leading from the tank to the engine. Fig. 3 is a longitudinal side elevation of the combined motor-carryingand auxiliary vehicles opposite to that seen in Fig. 2, showing the powertransmitting devices to the threshing-cylinder.

Similar letters of reference indicate corresponding parts in all the figures.

Referring to the drawings, A represents the horizontal motor-supporting platform, which is mounted upon the traction-wheels B B at a point nearly equidistant from both ends of said platform.

0 represents the horizontal platform of the auxiliary vehicle, and is connected pivotally at the forward end by means of the ordinary king-bolt with the axle c, at each end of which axle are the guide-wheels C O. The platform 0 of the auxiliary vehicle is raised in position a considerable height above the line of the platform A and its rear end portion extended directly above and in parallelism withthe forward end of the platform A and to a point a short distance in advance of the point of connection of the traction-wheels B B with said platform.

The platform A is less in width than the A platform 0 for the purpose of affording room for the operating-gear hereinafter described.

To the forward end of the platform A is attached the lower end portion of a' bracket a, the upper end of which bracket is attached to the platform 0.

For the purpose of illustration I have shown upon the platform 0 an ordinary threshingmachine D, inclosed by thevertical side Walls 01 (1, ends cl (Z and top (1 To the upper rear end'portion of the threshing-machine D is connected a rearwardly-extended chest (1, which is provided with a cover (1 and within which chest is a threshing-cylinder d mounted upon a journal (17, which journal extends IOC through the side of the chest d and is provided on the outer end with a pulley (i To the rear end of the chest (1 and in line with one outer side portion of said chest (Z is attached the upper end portion of a standard (I the lower end portion of which standard is attached fixedly with the motor-supporting platform A at a point directly over the axle of the traction-wheels B B. Upon the other side of the threshing-machine and attached to the end of the case (1 is a standard (Z which is the same in construct-ion as the standard To the upper end of the standard d is attached one end of ahorizontal bar (1 the other end of which bar extends rearwardly a short distance and is supported by the brace-bar (Z Upon the standard (Z is attached a bar which is precisely the same as the bar (1 and braced in the same manner.

For the purpose of enabling the weight of the rear end of the platform O and its load to be carried by the platform of the motorvehicle a truss-rod (t is connected with the forward end and side portion of the platform A at one end and the other end extended to a point near the outer side portion of the upper end of the standard (Z and secured adjustably to a lug a in said standard, the rod a being bent slightly in passing the end (Z of the machine D. To the rear end of platform A is connected one end of a trussrod (t the other end of which rod is secured adjustably to the lug a on said standard. Upon the other side of the platform A are truss-rods connected with standard (Z in the same manner as described of the truss-rods a".

Upon the rear end of the platform A is arranged, in a parallel position, the cylinders E E of a gasolene-engine.

Upon the upper side and extreme rear end portion of the platform A are the journalboxes ff, in which are mounted, in a trans verse direction to the platform A, the crankshaft F. In each cylinder E E is a pistonrod F, which is connected with the respective cranks upon the crank-shaft. Upon the top 61 of the threshing-machine D is a gasolene-tank G, with one end of which is con nected the upper end of a conducting-pipe g, the other end extending in a downward direetion adjacent to the side (1 of the machine to a position a short distance above the platform A, thence bent at an angle, and the other end connected with the inlet-openings to one of the cylinders E and by means of a branch pipe with the other cylinder E. Beneath the cylinders E of the gasolene-engine is a closed air-purifying chamber H, which consists of a rectangular frame attached rigidly to the under side portion of the platform A. In the lower part and forming the bottom to said chamber is a closely-fitting rectangular frame 7, over which is extended a cover 1?, of chamois-skin, the outer edges of which skin extends over the edges of the frame Z and is secured to the outer sideportion by tacks or other suitable manner, as seen in Fig. 1]. The bottom of said frame is composed of cloth t the outer edges of which are extended over and secured to the sides of the frames in the same manner as described of the chamois-skin i. To the cylinder E of the gasolene-engine is connected the air-pipe c, the lower end of which pipe extends downwardly and through the sides of the chamber 11 to a point above the screen 1'. Connected with the pipe 6 is the jet-pipe e for the gasolene, so as to mix the oil with the air before entering the cylinders,as commonly employed in gasolene-engines.

To the outer end of the crank-shaft 11, which extends a short distance from the direction of the side of the platform A, supported by the traction-wheel B, is attached a balance-wheel K, and upon the other end of said shaft, which extends a corresponding distance from the direction of the side supported by the traction-wheel B, is attached a band-wheel K. Over the band-wheel K is extended one end of a belt or band It, the other end of which belt is extended over the pulley (Z on the shaft (1 of the threshing cylinder (1, and the two ends connected together in the usual manner. The tension of said band is regulated by the belt-tighteuer on the standard cl 011 the inner side of the traction-wheel B and secured rigidly to the spokes on said wheel is acog-gear L, concentric with the axis and about one-half the described diameter of said wheel. Upon the inner side of the traction-wheel B is attached fixedly a coggear L, which is precisely the same in construction as the gear L.

In the direction of the rear end of the platform A, and journaled in suitable boxes 011 the under side portion of the said platform a short distance from the gear L on wheelB is transverse shaft m. One end of shaft on extends nearly to the traction-wheel B, and upon said end is a small gear M, which engages with the cog-gear L on the wheel B. On the other end of shaft on is a gear M, which meshes with the cog-gear L on the wheel 13.

On the shaft m, between the gear M and the adjacent side of platform A, is fixed the differential or compensating gear N, which is the ordinary gear in use for increasing the velocity of one traction-wheel in describing curves in the track, and as more clearly shown in Fig. 10, which shows the larger spur-wheel a, the bevel-gear a, and the beveled pinions 77?, whereby in turning a curve one of the traction-wheels is accelerated in the same degree in which the other is retarded. Upon the crank-shaft'F, a short distance from the balance-wheel K and feathered on shaft F, is a small movable gear 0.

Upon the side of platform A, at a point nearly equidistant from the respective gears a and 0, is attached the gear-shifting device I. Said device consists of separate flat plates 19 p of equal size and arranged a short dis-' tance apart and secured in said position by bolts 1?. The plate 1) is secured rigidly to the side of the platform A in nearly an upright position. In the outer plate 19 is a curved slot 19 which is described from the center of the shaft m, carrying the differential gear N. Between the plates 19 p is a sliding plate 19 which is narrower in width than the plates 13 13, so as to move between the bolts p 19 which unite the sides of said plates p p. In length the sliding plate 13 is also shorter than the plates 1) p, and upon the face of said plate opposite the slot 13 is attached rigidly a journal 19 which extends through the curved slot 19 upon which journal is a large cog-wheel R, which engages with the cog-wheel n on the shaft m. On the upper end of plate p is an ear 19 to which is pivotally attached a link 19 On the upper ends of the respective plates 13 p are ears 19 between which is fulcrumed a lever 19 the inner end of which lever is pivotally connected with the link 19 on plate 19 the end of the lever extending in the direction of the rear end of platform A.

To the lower side and rear edge portion of the plate 19 is attached fixedly a horizontal extension 1), upon the face of which is a sleeve 19 in which sleeve is inserted one end of an operating-rod p. In the rear edge portion of the plate 19 are notches 19 p", ar-

ranged one above another and beneath the line of the journal p which receives the inner end of the rod 13 Upon the inner end of the rod 19 which enters the notches in the plate 19 is an enlargement 19 On the rod 19 between the enlargement p and the inner end of sleeve p is a spiral spring 19 The outer end of the rod 19 extends to a position near the rear end of platform A and is connected with a bell-crank operating-lever S, pivoted to the side of said platform.

For the purpose of reversing the movement of the traction-wheels B B and the intermedi ate gear for transmitting power from crankshaft F to said wheels upon the crank-shaft F is loosely connected the upper end portion of a flat swinging plate T, upon the lower edge portion of which is a flanged extension t on both sides of said plate, which is curved in a described line the center of shaft F. On the outer side portion of the swinging plate T is a journal t, upon which is a pinion which meshes with the gear 0 on shaft F and is thrown into engagement with the cog-wheel B. On the side of the platform A, beneath the lower swinging end of the plate T, is a grooved guide plate or shoe U, the bottom of which is curved at u and perforated at a in a vertical direction. To the outer side and lower end portion of plate T is pivotally attached the inner end of an operating-lever W. Between the pivotal point of the lever IV on plate T and the outer end of said lever is a locking-rod w, pivoted at its upper end to said lever, the lower end entering the perforation u in the bottom of the grooved guide in plate U.

For the purpose of operating the forward axle and changing the direction of movement of the vehicle a rod V extends from a point near the balance-Wheel K along the side of the platform to the forward end of said platform and is provided with a worm-gear c, which actuates a pinion c on the shaft 0 around which shaft is looped a chain if, one end of which chain is attached to one end of the axle and the other end to the outer end of said axle.

For the purpose of preventing dust, &c., enveloping the engine a horizontal fixed shield or plate X is attached to the standards d d a short distance above the cylinders E E of the engine and extends horizontally to a position over the extremity of platform A and is nearly of the same width as said platform. Said shield is supported by the rod w, extended from the outer edge of the shield to the bracebar c1 To the outer edge of shield X is attached one end of a cloth curtain Y. The other end of the curtain is extended entirely around the rear end and sides of said shield and downwardly to the platform A. Beneath the chest 61 containing the threshing-cylinder, is the water-tank Z for supplying water to the water-jacket of the engine in the ordinary manner.

In the operation of the improved motor-propelled vehicle the gasolene-engine which is employed renders the operation of the vehicle, which contains in threshii'ig-machines combustible substances, free from danger by fire, and as a motor the employment of the threshing-machine may be readily made within the walls of a granary or within the barn.containing the wheat to be threshed and thus out of exposure to weather. The dust arising from the machine is purified in passing through the screen Z and excluded by the shield K.

After starting the engine and for the purpose of operating the threshing-machine the gear 0 is moved by hand out of engagement with the gear R and pinion 25 in the direction of the balance-wheel N, into the position as seen in dotted lines in Fig. 1. The power from shaft F is transmitted to the band-wheel K, and thence by the band or belt 1:; to the threshing-cylinder d, and the threshing or other work continued without loss of power in its transmission. When the movement of the vehicle is desired in a forward direction, the engine is stopped and the gear 0 moved into engagement with the gear R on the shifting device and the pinion t on the swinging plate T. The engine is then started and the power transmitted from shaft F, through the gear 0 and R to the differential gear N, and thence to the traction-wheels B B, the direction of movement being controlled by the rod V, which actuates worm-gear o and the pinion 1; and the shaft '0 thus winding one or the other portion of the chain '0 and moving the axle of the forward wheels 0 O.

gear R, n, and M.

In changing direction of movement the differential-gear N permits one of the tractionwheels B B to turn faster than the other and describe a short curve. W'hen the movement of the vehicle is desired in a reverse or bacle ward direction, the lever S is operated and the end of the rod p is withdrawn from the notch in the plate p and the plate lowered in position, the rod automatically engaging the notch above and interlocking, so as to hold the plate in position. In this movement the gear R preserves engagement with the cog gear at on the shaft in. The lever "W is elevated sufficiently to lift the bolt to out of the perforation u in the groove to of the guide U and the lower end of the swinging plate T thrust forward and causing the pinion t to engage with the gear R. The power from the shaft F is then transmitted to gear 0 and I and the gear R, and thence to the differential gear N and to the traction-wheels and reversing the direction of rotation of the said The bolt on lever V is then placed in one of the perforations a and the plate T held firmly in position. As soon as movement of the vehicle is completed the lever \V is operated todisengage the pinion 1? from gear R, and the gear 0 shifted so as to throw said lever out of engagement with the gear 25 and the power of the engine is then transferred to the band-pulley K, or the gear-shifting device operated to throw the gear B into engagement with the gear 0, as the power is required.

Instead of the threshing-machine D, I may employa receptacle for grain, using the power of the engine to effect its removal, thus making a motor-wheel of great utility and of great adaptability when change of location is found necessary. The equipoiscd trussed platform enables the great weight of the threshing-machine to be sustained, and with the motor a counterbalance is obtained, the weight of the threshing-machine offsetting or reducing the vibrations of the platform during the operation of the engine.

Having fully described myinvention, what I new claim as new, and desire to secure by Letters Patent, is-

1. In a motor-propelled vehicle, the combination with an equipoised trussed platform having traetioinwheels of a motor at one end ofsaid platform and an auxiliary or separate platform having traction-wheels at one end, and an endwise bearing upon the end of the motor-supporting platform opposite to said motor, and suitable connections of one of said platforms with the other, substantially as shown and described.
