thatupon the starting or increase in speed ti res of my invention, it-ma y here he noted of many vehicles now in common use, the

,phssengers --0r freight thereon Qjare subjected,- onaccount of their 1nertia,toa'more or less violent shock, rendering riding Toftendisagreeable and "sometimes unsafe, 1 A simifound that the. abov e defects are due in 1 a considerable measure to" the lack; of, uni

torinity ofvchange insped or snddenness of change from or to a state of rest, "and I. prochange more uniform -endgraidnal. It may tilsohere-be noted th-at-j'pass'engers are exposed to a somewhat similar effect upon the vehicle rounding curves, due to centrifugal force. Thislast-mentioned effect takesvplace' to some extent even uponslight curves and results notonly in the above idisco'm rt -to passengers but in a considerable iiiSon the-roadbed 'a'tthe point at which same takes place. As these: last-mentioned-jefiects'z obtain to some extent uponslight ctirv es, 1s sometlmes impracticable, even with .ja,-ca're-' ful engineer or other operator, -.entirely to! prevent. the same.

Theziboi eaIid other 'de- 'fects are-remediedflin constructions-ofthe nature of those hereinafter described.

Referring now to the illustrative emb ocliin Fig. 1 a vehiclehlO which. in thlSFlllllj'lStl'fl-E tive embodiment is inthe form offa'n electrically -propel'led car deriving'current from a trolley Wire 11 through aitroll'ey 'poleil fl,

conductor 13 and a; controller 1-4. Leading from this controlle'r is aconductor 15fel ec triczilly. COIIIlCtGd, "51's he'r'einafter described,- n'ith a motor 16. -from which .thencircuit is carrie'chto the rai1'17' and completed in any 'Mo'iinted npon the -vehicle asbfv the pivotal so asitobe adaptedito nropelthe vehicle 10.

s ipport 18, or inany'otl eiibroadlv equivalent manner. is iv'hat maybe termed a heme '19 having thereon arigid arm 20. ointedto a bisfto11-rod21; as is-hest-shown- 1n Fig/2 of the drawings. The latter member is connected with a piston 22 vposi'tiio ned ina cylinder 23;

reln tiomto the vhic'leias port Piston 22 is perforated as shown at 26 and is thus adapted to move slowly through the fluid and act as a retarding device controlling the position of the swinging frame 19. in this manner, frame 19 is permitted to occupy a substantially vertical position irre-.-

spective of the inclination of the vehicle and yet any sudden swinging movement thereof 1s prevented. It may here be noted. that by the term inclination as used-throughout this specification and the following claims "with reference to a vehicle, is meant the po:

Mounted upon frame 19 is anabutment 27- having positioned adjacent thereto a'pile of tension of Wllllf-IS adjustable by nuts 31.

or equivalent device. Cond-uctor15 passes.

carbon blocks or other variable resistance medium 28, electrically connected with what may be termed a yoke 29,, also insulated from the frame. This, yoke is normally held against the "ariable resistance medium 28 as by mearisgof springs 30, the effective preferably adjacent pivotal point 18 and thence to a binding post .32 electrically connected,.as by means 'of conductor 33, with the abutment 27. The circuit leads thence through variable resistance medium28, yoke 29 andagcdnductor 34 to a binding post 35 connected, as by means of conductor 36, with I the motor 1.6.

Secured to yoke 29 is a flexible member 37, preferably a cord, wire or linkage, terminatingat a fixed point 38 and guided by. insulating'pins as shown at 39 and 40; Ad ditional guides 41 adjustable toward and away from one another as by wing nuts 42 are preferably provided so'as to insure that the effect of any such displacement upon the yoke 29 will be. in a direction substantially directly away from the variable resistance 28. betweenthese pins is a weight 43 of any desired form and preferably 'comprising a plurality of parts soas to be adjustable in efi'ect. This-weight normally rests in contact with a suitable abutment 44, best shown in Fig. 3 of the drawings, which prevents a forward movement thereof, assuming the car to be traveling in thedirection indicated the arrow in Fig. '1, and yet permits a substantially free, lateral or lagging displacement; There is also preferably mounted upon the frame an abutment 45 having thereon a resilient insulating washer or gasket 46 against which is positioned a car-' bon disk or other electrically conducting member 47 preferably substantially of the shape indicated. A succession of gaskets 46 ting with a series (if-disks 47, the adjacent aces of the clisks being Mounted upon this .member pretation of certain terms used throughout:

slightly separated one from another and the lowermostgasket being supported by a yoke 48. This yoke is connected as by .means of a spring 49 with a lug 50, the

tension of the spring being adjustableas by means of nut 51. The upper portion of yoke 48 is provided with an insulated lug to which is connected a member 52 flexible in effect and supported by means of the adjustable spring 53 vupon a lug or projection 54; Suitable guide pins are positioned. adjacent member 52 for a purpose similar to that'of the guide pins 39 and 40,

above described. Mounted upon member 52 is an adjustable weight 56 resting in contact wit-h an abutment 57 and preferably positioned within a curved recess 58 therein,

as is-shown in Fig. 30f the drawings,- so as to prevent lateral movement of this weight, or lagging thereof with respect to the direction of travel of the vehicle. It may here be noted that by the term lagging, as used. throughoutthis specification and the following claims, is meant arelative movement in a direction away from the direction of movement of the vehicle.

The abutment 45 is in electrical connection, bymeans of a conductor 59, with a binding post 60, which in turn is connected with conductor 13, through a suit-able switch 61, and a connection 62 is provided from the yoke 48 to the binding post 35 andthence v through the motor 16, asabove described.

The electrical connections of this illustrative'embodiment of certain features of my invention may be briefly reviewed by this-description or the following claims, it

may here be noted that the term vehicle is used in its road sense and the expression inertia controlled 1s used to denote that-charact-eristic of a body by virtue of which it is adapted to change its position or condition relative to another. body by reason of its inertia. It-may also here be noted that by inertia l" is'meant tendency of a bodyto resist change to or from a state of rest or change in the rate of speed at which, it travels. v

The operation of the above illustrative embodiment of myinyention is substantially as follows: Assuming that the vehicle is started .suddenly, as by completing a 011'- .cuitthrough the controller.14, the same will tendto lurch forwardjhnd the weight 43 by virtue of its inertia will tend to lag to- .bet 7 to be displaced and to draw upon ke 29. In this manner the pressure evanable resistance 28 is released to a 1 at'cr/or'less extent and the electrical resistance thereof.proportionately increased, thusten'ding to cut down the current flowing through the motor 'and to affect its speed or the rate of increase of its speed. In

this manner, by a' suitable adjustment of the variable resistance, the pressure thereon, the weight and other factors, the tendency of the car to lurch forward 'is checked to any desired extent and the weight 43 then returningt-oward the abutment 4a the variable resistance isvagain reduced and the current supplied "to the motor proportiosjiately sed. The forward lurch of the car is lllblefl H thus transformed into a series of quickly succeeding anctmiliute lurches of any de sirechmagnitude.and the speed thereof thus built up substantially urifcrmly tothe desired point. By. proper adjustment, this rate of increase ofspeed may be regulated until the caris started as suddenly as is desire and yetwith .a material gain in the uniformity ofaccelerat-io-n. 7 It will be .seen that the quickly succeeding impulses by which the speed is built or cut down may be of such an exceedingly minute characteras to render the rateof change ofspeed substantially uniform. .Theabove would hold true to a greater or less extent irrespective of the value to which the resistance is increased,-and manyof the advantages of this invention would be'obtained if the resistancewere brought 'to an infinite value.

as by a suitable proportionment of weights, springs and other factors. The above effect takes place in a substantially-identical manner upon the sudden increase ,ofspeed of. the car while the same is running.

Upon the vehicle rounding a curve the Weight {l3 is laterallydisplaced with re'-' spect to the direction, of travel, due to its centrifugal force, and a corresponding decrease in current supplied to the motor re sults on account of'the increase in-the variugal force uponrounding a curve the de-- sired magnitude without altering the weight.

r or changing the effect of the lagging of the same.

shown mounted upon the frame 19 is, to a certain'extent, the contrary of the first mode 'of operation described inasmuch as the Weight'56 is adapted upon a decrease in speed 'of'thecar, or the stopping thereof, fde lnove I forwardly, in the direction of [The operationsef the remaining devices- Increment of the car, and, by means of the flexible member 52, draw upwardly on the yoke 48 and compress the several resilient gaskets 46 so as to bring thedisks 47 into more or less intimate contact, In this man- 'ner a greater orless current is supplied to the inotor ld'independent of the condition of controller 14, and the same is driven in. a forward direction so-as to neutralize the too sudden retarding'elfect'of the brakes 64- or equivalent means actuated by air cylinder 64s or any other desircdmechanism.

Switch 61 provided so' as to cutout the. last described mechanism, if desired.

The retarding device or dash-pot piston 22 operates in a well known manner to pre vent a quick swinging of the frame 19 with desired result, may nevertheless perform their functions independently and many of the advantages of the con oint use be real- -a consequent decrease in effectiveness of the ,weights l3 and 5G-an'd. yet to permit a slow bcseen that l have provided I ized. It will also be seen that the apparatus above described although distorted for pur-I posesofillustration, may be formed cheaply and compactly and be readily and ineXpen-' sively mounted upon'vehicles, 'now' in use. Moreover, by virtue of a direct control by means of inertia, to which are due many of the defects which it is desired to eliminate i in apparatus of the general type above described, it'is well adapted exactly to overcome these defects. I I

Although I have set forth what I-believe to be the exact mode of operation,nevertheless I do not intend that this invention be limited by statements of-theory of action herein made. v

In Fig. of the drawings is shown. a different embodiment of certain-features of my invention, indicativeof its broad character, in which a weight (35, upon a yehicle G6 is supported by means-of an adjustable spring GT'fand is connected as by a flexible I member 68 with a band brake (39 operatively' mounted with relation to one of the wheels of. the vehicle. A. suitable abutment T0 is provided to prevent forward movement of the same and it will readily be seen that by virtue of the lagging or lateral swinging of thisweight. many ofthe advantageous features of the above described embodiment arerea-lized. y 31's n iany changes could be made in the above construction and many apparently widely different embodiments of my inveni 55 rate of change of speed thereof.

I desire it also to be understood that the language used in the "following ClillIIlSlS' intended to cover all of the generic and specific features of the invention herein clescribed and all statements of the scope of the inventioinwhich, as a matter of language, might be said to fall therebetween,
