To all whom it may concern.'

Be it known that I, CHARLES E. ROBERTS, a citizen of the United States, residing in Oakpark, in the county of Cook and State of Illinois, have invented a new and `useful Improvement in Automobiles, of which the following is a specication. h

My invention relates toautomobi1es, which term is herein employed as aA generic designation of all motor-vehicles, carriages, or velocipedes, and the improvements vhave reference more particularly to the means for or torque desirable undersuch conditions to allow the motor a slight start before it begins to actuate the gears is provided for by a dexible connection between the motor and `the motor-pinion. This is` one oftheA main features of the invention.

A further object of my invention is to simplify the running-gear, whereby the same may be made to removably clamp and support one or Ymore motors and will be rigid and strong, permitting the readyremoval of either motor independently of the other.

A further object of myinvention is `to hold the forward axle rigidly against horizontal oscillation While permitting it to oscillate vertically; and a still further object of my invention is to completelyincase the gears and, if desired, the motor and all moving connections between the motor and gears.

With these ends in view my inventionlcouunderstood from such description when read .board 22.

in connection with the accompanying drawings, in which- Figure l is a sideelevation, partly in section, of my improved automobile. Fig. 2 is a front elevation,partly broken away. Fig. 3 is a rear elevation. Fig. 4 is a plan ofthe running-gear. Fig. 5 is a perspective of the two axles and the connections between them. Fig. 6 is an enlarged horizontal section of one of the motors and its driving-gears. Fig. 7 is a section on the line W W of Fig. 6.

`In said drawings, 20 represents the body ofA the` automobile, having a seat 2l and dash- The body is supported at front upon a single spring 23, arranged parallel witband over the front axle 24 and at the rear upon side springs 25, arranged over and at right angles to the rear axle 26. The front spring is seated upon and clipped to a block 27,pivotally secured to axle 24 and capable of rocking endwise independently of the axle, being fashioned, as best seen at Fig. 5, to set down over and stradd'le the axle and secured thereto by a bolt or pin 28, passing through the depending members 29 of the block. The rear springs are clipped to axle 26 in any ordinary manner. The front wheels 30 turn on stub-axles formed on or secured in swiveled heads 3l, attached to axle v24 by vertical pivots 32 in the customary way and are controlled in steering by arms 33, connected together by the rod 34, which is united to both of them by spherical or universal joints 350. The rod 34 is actuated longitudi-A `body of the vehicle and having its lower end forked, so as to set over the crank 37, which is flexibly joined to it by pivot 33, and said crank being joined to a bracket 39, rigid upon rod 34, by a spherical universal joint 40. In the joints 35 and 40 the spherical shell or outside member is arranged with its opening for receiving the other member at the. loot-V tom, so that the shell is adapted to shed rain and dirt falling onto it.

The

axles

24 and 26 are connected together by twin reaches 45, rigidly attached to the latter and having loopsV 46 encircling the former. These loops allow independent rocking by axle 24, being `provided `with vertical sides, so that they guide the ends of the axle as they rise and fall witho ut interfering otherwise with the movements. The loops or the ends of the reaches to which they are attached are both joined to the springsupporting block 27 by arms 47, rigid andgpreferablyintegral with the said block, so that the reaches control the rocking of said block and the front spring,while allowing full independent rocking movement to the front axle.

The reaches are fashioned, as plainly shown at Fig. 5, so that their rear ends are adapted to receive and clampthe electric or other motors employed to propel the vehicle. The parts which thus. act are upper and lower semicircular arms 48, conforming to the exterior of the motors and adapted to be bolted to the rear axle, as at Figs. 1 and 3. A filling-block 49 may also be used between the turned-out ends of the arins,as shown in Fig. 1. The arms48 exertsuch holding powerupon the motors that the latter need no other fastening whatever to the vehicle, and the motors are thereby also rendered very rigid with the rear axle. The motors are inclosed in cases, preferably spherical, and each composed of

hemispherical sides

50 and 51 and a central ring 52, as will be understood from Fig. 6. The side 51 is provided with a separable portion 53, surrounding the axis and united to side 51 by bolts 55. The

parts

50, 51, and 52 are united by bolts 54, and the

parts

50 and 53 receive and support the cups 56 of the ball bearings provided for the shaft 57 of the motor-armature 58. The casing side 50 also supports the brushes 59 in position over the commentator-60.

64 represents an adjustable plate supporting the brushes, and the head of a plug closing an opening giving access to the brushes. These features are not fully described or illustrated, as they form no part of the claims herein.

The preferred construction of the mechanism connecting hand-lever 85 with the levers 84, by which the brakes are set, is that illustrated, the lever 85 being on the end of a shaft 90, carrying a crank 91, connected by a vertical rod 92 to an elbow-lever 93, pivoted at 94 and having its further end forked or otherwise-adapted to embrace a horizontal rod 95, adjacent to the nut 100 on the end of the rod. When the rider moves lever 85 backward, the parts described will cause a forward longitudinal movement of rod 95, and as said rod is joined to the center of a cross-bar 99, connecting the operating-levers 84 of the brakes of the two motors, it will be seen that the brake-shoes of both brakes will be set in operation thereby., The movement just mentioned of the rod 95 will also store up power in the spring 96, which encircles the rod and is conned thereon between the collar 97, secured to the rod, and the stationary stop 98, so that when the driver releases the lever 85 said spring-will return the parts to normal position. The electric currents may be and preferably are controlled by the same lever 85, and a portion of the mechanism for that purpose may consist of the segment 101 on the shaft 94 and the-pinion 102. This mechanism is not completely shown, as its construction is well understood.

Not only are the motors rigidly held by the reaches, so that they have no movement independent of the rear axle, but I also couple them together, so that neither can move independently of the other and so they will remain in alinement with each other. This is done by means of a tubular connection 103, having outstanding fianges 104 and flanged nuts 105, threaded on the exteriors of the axial projection 106 of the parts 53 of the casings of the two motors and engaging the flanges 104.

The armature-shaft 57 of each motor actuates a shaft 107, carrying a pinion 108, meshing with and driving the gear 109, mounted loosely on the rear axle 26, but rigidlyjoined to one of the rear wheels. These gears are inclosed in a casing consisting of side plates 110 and 111 and a rim 112, and the shaft 107 is stayed from the axle 26 by a strong metal bracket 113, iitting the enlargement 114 on the axle and also inclosing the shaft and supporting the cups 115 and other outer parts of one of the ball-bearings provided for said shaft 107. The cup of the ball-bearing at the other or outer end of said shaft is shown at 116 and is supported inanut 117,threadedinto the shaft-cavity and formed partly between the bracket 113 and partly by the side platellO. The cone opposed to cup 116V is shown at 116 and is locked in its adjustable positions by a screw 116l. large enough to admit pinion 108 and is closed by cap 118, so as to exclude all dirt and moisture at that point.

The shafts 57 and 107 are not made absolutely rigid with each other, but, on the contrary, are coupled together in a manner which not only provides the necessary elasticity or torque permitting the motor to move slightly in advance of the driving-gears, notwithstanding both are rigidly held so that they cannot change their locations with respect to each other, but which also permits the very ready disconnection of the two when necessary for repairs or other reason. The coupling device is a dat bar of metal 120 let into slots 121, formed in the proximate endsof the two shafts. The bar is loose in the slots, but cannot escape therefrom so long as the retainingrings 122, which are placed over the shafts and close the edges of the slots, are in place. To disconnect the shafts, it is only necessary to take off one of the rings, when the bar slips ont of its slots very easily.

The casing of each motor is also joined to the adjacent bracket 113 by connections adapted to be readily separated and to prevent access of wat-er and dirt to the ends of the motor and pinion shafts and the couplingbar just described. These connections con- The shaft-cavity is made' IIO tially as specied.

sist of two tubular and

telescopin g sections

123 and 124, each entering one of the annular grooves 125 or 126, formed in the retaining-- rings 127 and 128 of the ball-bearings. After being entered in the grooves a ring-nut 129, threaded on the smaller section, is turned up against the larger section and keeps the sections expanded, so that they cannot 'escape from the grooves. Itwill be noticed that these covering-sections are easily positioned and as easily disconnected from the casing an bracket.

By connecting. the operating-levers 84 of the brakes of the two motors by the equalizing-bar 99 I am enabled to apply the handpower equally to both brakes by the use of a single hand-lever, and the mechanism also permits the setting of the brakes very quickly.

I hereby expressly reserve for a divisional application, filed December 14, 1900, as Serial No. 39,846, any claims to which I may be entitled based upon the brake mechanism herein shown. Y
