RUNNING-GEAR FO'R MOTOR-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 631,627, dated August 22, 1899.

Serial No. 708,755. (No model.)

To all whom it may concern:

Be it known that I, JOHN WASHINGTON EISENHUTH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and usefulImprovements in Running-Gears for Motor-Vehicles; and I do here by declare. the following to be a full, clear, and exact description of the invention,such' as will enable others skilled-in the art to which it appertains to make and'use the same;

My invention relates to improvements in running-gears for motor-vehicles; and it consists in a runningfgear comprising front guidewheels-and rear wheels, one or both of which may be employedfor propelling the vehicle, the propelling-wheels being provided with internal gearing, a pinion for engaging said internal gearing and mounted upon a suitable shaft, whereby it may be connected with any suitable means of propulsion, the construction being such that dust or dirt is excluded from the gearing.

It also consists in arunning-gear comprising drive-wheels and front guiding-wheels, the said guiding-wheels being mounted upon independent shafts, segmental gears secured to each of the said shafts, and intermediate connecting-gearings providedwith hand operating means for moving the segmental gears simultaneously to turn the guiding-wheels.

It also consists in certain other constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a top plan view of my improved motor-vehiclerunning-gear, portions of the samebeing shown insection to better reveal the construction of the parts. Fig. 2 represents a longitudinal Vertical section through the said running-gear upon a line passing through one of the steering-heads. Fig; 3 represents a front elevation of the steering apparatus. Fig. 4 represents a top plan View of a portion of the said running-gear, illustrating a different means for bracing the framework thereof; and Fig. 5 represents a similar view showing the manner of strengthening the said frame when it is designed for use upon-heavy trucks.

1 in the drawings represents my improved motor-vehicle running-gear, 2 the rear Wheels thereof, and 3 the front or steering wheels.

The rear axle 4 is mounted ina sleeve, as 5 5 5, forming a part of the frame of the vehicle. The axle 4 projects beyond the sleeve 5 at each end thereof and carries the rear wheels 2 of the vehicle. The rear wheels 2 are preferabl y formed with inwardly-extending hubs, as 6, between which and the axle 4 are interposed 1 roller bearings, as 7. Antifriction- Washers, as 8 8, are interposed between the ends ofrthe rollers in the said bearing, and an antifriction-washer, as 9, is interposed between the hub 6 and the end of the sleeve 5. The hub 6 is held in position upon the axle 4 by means of a nut, as 10, engaging suitable screw-threads formed upon the ends of the axle. The ends of the axle andthe nuts 10 7o are preferably inclosed by a dust-proof cap, as 11, which is screw-threaded upon a portion of the hub 6. The rim of each wheel 2 is preferably formed in two parts, one portion, 12, of which is formed integral with the Web'portion extending to the hub 6, while the other portion, 13, engages ball-bearin gs which are interposed between it and a disk, as 14, formed upon the sleeve 5., Theportion 13 of the rim is suitably joined and secured to the 8b portion 12, the two parts forming a peripheral groove to receive a tire, preferably of rubber, as 15, said tire being of any suitable or desired construction. Upon the inner periphery of the rim portion 12 is formed an internal gear, as 16, said gear being located approximately upon the central vertical plane of the wheel. The gear 16 is adapted to be engaged and actuated by meansJof a pinion,

as :17 which is secured upon the outer end of 0 a shaft 18, mounted in the frame 1. This shaft 18 finds hearing at its inner end at 19 in the frame of the running-gear and preferably has an end friction-bearing, as at 20, in the said bearing 19 to receive its end thrust. 5 The shaft 18 also extends through the disk 14 and is provided-with a suitable bearing, as at 21, formed therein. The shaft 18 may be connected in any suitable manner with the motor for receiving power andthuscommu- 10o nicating the same through the pinions17xto the internal gearing 16 or rotating the drive wheel or wheels and propelling the vehicle.

It will be noted by examining Fig. 1 of the guiding-wheels.

drawings that the rim 13 is comparatively small and extends only a short distance toward the axial point of the wheel. The disk 14, on the other hand, is of considerable size and reaches to within a short distance of the said rim portion 13, thus closing the internal gearing 16 entirely within the wheel and protecting it from dust or grit of any kind. Since the rim portion13 moves with the wheel 2 and the disk 14is stationary,I employ rollerbearings, as 22, which are interposed between the peripheral grooyes formed in the said rim 13 and the disk 14. These grooves form seats or bearings in which the balls may run. In order to protect these bearings from dust or other foreign substances, I form an overhanging flange, as 23, upon the disk 14, as seen in Fig. 1.

'Both of the rear wheels 2 maybe constructed in the manner above described, in which case a second shaft, like the shaft 18, wilLbe employed and connected with a source of power for communicating movement to the wheel upon the other side of the vehicle.

The steering mechanism also forms an important feature of my invention. The front wheels 3 are mounted upon short shafts, as 24, roller-bearings, as 25, being interposed between the said wheels and the said shaft to reduce the friction. To the innerends of each of the short shafts 24 are secured vertical guide-spindles,as 26,which find suitable bearings in the guide-heads 27, formed upon each side of the vehicle. Each of the steeringheads 27 is formed so as to receive upper and lower ball-bearings, as at 28 and 29, which engage the said spindle 26 and support the same in its vertical position. The lower balls 29 rest against a peripheral shoulder 30, formed upon a spindle 26, and engage a raceway, as 31, formed in the lower end of the head 27. The.upperballs28 run in a suitable raceway, as 32, also formed in the head 27, and both of the ball-bearings thus formed are adjusted and held in place by means of a cone, as 33, secured in place upon the spindle 26. This cone 33 is held in place by means of a washer 34 and aeap or nut,as 35. A binding-nut, as 36, holds the cap-nut 35 against accidental displacement. It will thus be seen that each of the wheels 3 is mounted so as to turn freely and in such a manner that there is little chance for friction between the parts. To the lower ends of the spindle 26 and just inside of the inner ends of the short shafts 24 are mounted segmental gears, as 37 37, the said segmental gears 37 37 being semicircular in shape. Interposed between the segmental gears 37 37 and meshing with each ofthem is an actuating pinion or gear wheel, as 38, secured to the lower end of a vertical shaft 39. The shaft 39 engages bearings, as at 40, in the frame of the vehicle and extends upwardly to a suitable height, being provided at its upper end with a hand operating-wheel, as 41, by which it may be turned to actuate the If desired, the haml-wheel 41 may be replaced by means of a hand-lever without departing from the spirit of my invention. The steering-heads 27 27 are preferably braced with respect to each other by means of rods or tubing, as at 42 42. These steering-heads 27 are also braced with respect to the frame 1 by means of diagonal tubing 43 43. The said tubing is connected at the front of the vehicle to each of the heads 27 and at the rear to bearings 21 upon the disk 14. The central portion of this bracing structure is held in place by a coupling, as 44. By crossing the tubing thus in the center of the vehicle a larger space is allowed for the turning of the wheels 3 upon their spindles. I also mount upon the coupling 44 antifriction-rollers, as 45, which limit the inner movement of the wheels 3 and prevent them from coming in contact with the braces.

In some forms of vehicles, where it is not necessary to use such heavy bracing, the tubing 43 may be replaced by means of diagonally-arranged cables, as 46 46, as illustrated in Fig. 4 of the drawings.

In making strong trucks for very heavy work it is sometimes necessary to further brace the framework of the vehicle to withstand the strain, and in this instance I employ brace-rods 47. (Shown in Fig. 5 of the drawings.) \Vhen the braces 47 are employed, the diagonal braces may be used or not, as may be desired. The bearing 19 is. braced with respect to the bearing 40 by means of a longitudinal brace rod or tube, as 48, and the said bearing 19 may also be braced with respect to the sleeve 5 by means of a rod or bar, as 49.

It will be evident from the above description that I am enabled to produce a runninggear which is particularly well adapted for motor-vehicles and one in which the drivinggearing can be completely inclosed to protect it from dust or other foreign substances which are detrimental to the same. It will also be observed that the steering mechanism is of a simple and yet effective construction and that it can be readily controlled from the vehiele.
