CHANGE-SPEED;GEAR-OPERATENG MEANS FR MOTOR-VEHCLES.-

Specification of Letters Patent.

.Application filed April it), 1?:15. Serial No. 20,430.

To all whom t may concern Be 1t known that l, WILLIAM H. Acerr,

a citizen of the United States, residing at' Batavia, in the county of Genesee and State f New York, have invented a new and useful Improvement in Change-'Speed--Gear- Operating Means for Motor-Vehicles, of which the following is a specification.

This invention relates to operating or shifting mechanisms for the change speed gearing of automobiles or motor vehicles of the kind nowk in general use, in which a change speed gearing is employed between the engine and the driving wheels of the vehicle for reversing the motion of the vehicle and changing the gear ratio with which the engine operates the driving wheels.

In these motor vehicles as commonly constructed a hand operated gear shifting lever is employed forA shifting the movable gear or gears of the change speed gearing for reversing the motion of the vehicle and changing the speed thereof. A clutch is also employed between the engine shaft, which turnsalways in the same direction, and the change speed gearing and this clutch is usually controlled by aV pedal which is depressed to release the clutch and is released to `canse the clutch to couple the engine shaft with the drive gearing 4of the vehicle. The change speed lever has to be actuated manually to place the desired forward or reverse gearing in action While the clutch is held released by means of the clutch pedal.

One of the principal objects of'this invention is to provide a practical and desirable operating mechanism for the change speed gearing by means of which the driver can, by thc movement of a conveniently located selecting lever or device, set the' mechanism for placing in action any desired change speed gearing and thereafter place the selected gearing into action by the operation of the clutch pedal. The operation of the selecting device does not shift the change speed gear but merely serves to select or determine thc gear which is to be placed in action, the shifting of the change speed gear being thereafter effected by other means, preferably by the clutch operating spring nnder the control of the clutch pedal. In this way the driver can at any ti1iie5eitlier whilethey vehicie inA motion or at rest, select any desired one of the several speed gearings andthcreafter place the selected gearing into action vby the operation of the clutch pedal without having to shift the change speed gearing by hand while holding the clutch pedal down to release the clutch, as is the case with motor vehicles as ordinarily constructed.

Other objects of the invention are to construct the mechanism so that the selecting lever or device can be arranged on the steering column. where it can be readily reached and easily operated without removing the hands from the steering wheel; also to provide means whereby the movable gear or gears of the change speed gearing can be shifted in opposite directions by like movements of the clutch pedal, thus adapting the mechanism to change speed gears in which the movable gear or gears are shifted in opposite directions to place different speed gearings in action; also to construct the .mechanism so that the select-ing device can be moved for any desired selection of gears and returned to the neutral position, or tov any desired different selecting position, without necessitating the actuation ofthe change speed gear; also to construct the mechanism so that the clutch pedal can be actuated to control the clutch in the usual manner without changing the' setting of the selecting means; also to provide locking means for preventing the accidental simultaneous actuation of more than one of the gear shifting devices, and for preventing the accidental release of the gear shifting devices from the operative shifting position; and to improve the mechanismin the various other respects hereinafter described and set forth in the claims.

A represents thecasing of the change the engine casing, C the steering column and D the clutch pedal of a motor vehicle, these parts being constructed and associated in the known manner employed in some makes of motor vehicles. The change speed gear, a portion of which is lindicated at E, Fi". 13, may be of any usual or approved construction and it is not shown or described in detail herein.

1 and 2 represent the' two gear shifting rods ofthe change speed gear. These 'rods are, as usual, arranged in the change speed gear casing to slide endwise in suitable i guides or bearings, one of the guides for one a, ieg. i. Tir@ of the rods being shown at is shown shifting or operating n'iechanisin - i 7, 8, 9 and view, showing the in the drawings in connection with a change speed gear which gives three different speeds in a forward direction and a reverse motion of the vehicle, two of the speed gear ings being placed in action by the movement of one of the shifting rods, as 1, and the other two speed. gearings being placed in action by the movement of the other gear shifting rod 2. The shifting or operating mechanism which actuatcs the gear shifting rods 1 and 2 is preferably inclosed in a housing or casingl 11 which is bolted or otherwise removably secured on the open topped change speed gear casing A- in place of the usual cover or top plate of the change speed gear easing. l

5 represents a rock shaft which extends transversely in the casing 4 above the gear shifting iods'l and 2 and is journaled in suitable bearings (i at the opposite sides of the casing -l.. Gear shifting wheels or gears 10 are mounted to turn freely .on the shaft 5, there beingin the construcl tion shown folir of these wheels. one for moving each of the gear shifting rods 1 or 2 in one direction for placing in action one of the gear trains of the change speed gear. Each of the gear shifting wheels has a series of gear teeth on one portion of its periphery and a notch 11' for the engagement ot' a dog for turning the wheel, the remaining portion of the periphery of the gear being preferably cylindrical. 12 represents a yoke or dog-carrier which is secured to the shaft 5 to rock therewith and carries a series of dogs or devices 13, 14, 15 and 16, adapted to be engaged with the gear lshifting wheels 7, 3, 9 and 10,*respectively, for causing the latter to turn with the dog-carrier and shaft 5. In the construction shown, see Figs. 3-10 and 13, the yoke is of substantially U-shape, having a. cross bar or portion which extends substantially parallel with the shaft 5 adjacentto the peripheries ofthe shifting gears, and end legs provided with collars 17 which encircle the shaft 5 adjacent to its bearings 'and are secured thereto, as by pins 18. 'Each of the dogs 13-16 is arranged to slide towardand from the mneratinggear shifting wheelxin a pocket 19, Figs. 5, G and 12, in the cross bar of the dog-carrier, and each dog preferably has a spring-actuated bolt 20 arranged to slide in a guide pocket or recess 21 in the body of the dog into and out of the notch 11 in the cooperating gear shifting wheel. A pin 21' extending through the dog, through a slot 22 in the bolt 20 and projecting at its upper and lower walls of the pocket 19 in the dog-carrier, retains the dog and bolt in position and limits the movements of the ,dog land of the holt. The dog is retracted i ends into slots 23 in the I ox* moved away .from the eoperating gear shifting wheel by a suitable spring 24, conveniently located in a springseat 1n the dog carrier and engaging' a lag or eer 25 on the dog, and a spring 26, preferahlj)rv confined in spring pockets in the dog and holt 9.0. is provided for projecting the bolt into the notch ll of the cooperating eea-r wheel. As shown, the dogs are staggered, the alternate (legst/13 and 1:3 being disposed lower Vthan the other dogs 14 and 16 for a purpose hereinafter explained, and for the sake of compactness of construction the springs Qdi are located 'at the upper sides of the dogs i3 and 15 and at the under sides of the dogs 14 and 18. -n'the normal or neutral position ofthe parts, lin which all of the gear trains of the change speed gear are ont. of action, the several dogs lf3-1G are retained. as v,hereinafter described, in their retracted positions with the bolts Q() out of engae'ement with the gear shifting wheels .PZ- 10. so that the dog-carrier can he rocked up and down Witlrthe rock shaft 5 without the dogs engaging and operating;d any of the gear shifting wheels. If the dog-carrier isswung,

downwardly and one of the dogs is moved toward the coperating gear shiftingY wheel, the springr holt 2O of such dogwill he shoved back into the dog against the action of its projecting spring hy the retaining device hereinafter descril'ied until the holt-2O of the dog-carrier `is `brought. to a position opposite the notch 11 of the gear shifting;r wheel, when the holt will spring into the notch 11 and connect the dog' to the wheel so that when the dog-carrier is swung np- Wardly the gear shifting wheel will he turned therewith.

The dogs are adapted to he engaged or coupled with their respective gear shifting wheels hy a selectingr device which is provided with a series of cam lng's or parts 31.

32, S3 and 34;, each intended to engage the oater end of one of the dogs iii- 1li for mov-V ,iner the doe' toward its cooperating shifting 2fzear. Each dog preferahlv has an end lug or reduced outer end having; a beveled face adapted to engage the coperating cam of the selecting device for movingr the dog in\'ardly, a1ul with a `flat end face 3G adapted to engage a correspondine'v fiat end face 37 on the cam for holding: thedog` in its projected position. The selecting device shown consists of a sleeve which is pinned or otherwise secured on a tlat faced oar 535% which is held from turning,y and arranged to slide parallel with the axis of the rear shifting` \'heels in suitable guide. hearings 35) and 4t) in the casing 4. lVhen the selecting device is inthe neutral or inoperative position. `shown in Figs. l and 4, the several cams 31- 34 are out of the vertical planes occupied hv tile cooperating heveled lugs of the severa-l dogs. In this position ot the parts the roch shaft and dog-carrier l2 can he, rocked up amldown without causing either of the dogs to engage and he moved byA the cams of' the selecting device. if, however, the selecting device is moved, for instance, to the right. to the position shown in Fig. 10, the first cain 31 thereof will be placed in the vertical'plane of the reduced end of the cooperating dog 13. so that if the dog-carrier is then swung downwardlyv the first doe1 13 will engage the cam 31 and be' thereby moved into engagement with the gear shifting wheel 7. in this position of the parts the third carn 33. as shown in Fig. 10, is located below and in the vertical plane of the end lug of the second dot,r 1l. lint on account `of the staggered arrangement 'of the dogs labove explained, this dog1 will not engage the cam when thedogr-carrier is swung downwardly, the movement of the dog-carrier not being sutiicient to cause such en- Ljagrementfand thus only the first dog 13 will he moved to engage the cooperating gear shifting,` wheel 7. The cams 3l-34 are staggered correspondingly to the dogs lil-4G., so that the several dogs can be actuated by like niovemei'lts of the dog-carrier when the selectingl device is properly placed.

ily moving' the selecting;` device 30 an appropriate distance the second cam 32 thereof is brought into operative relation with the second dog 14. and by successive further movements of the selecting,r device the third and fourth cams thereof can be placed in operative, relation to the third and fourth dogs l5 and 1G, respectively, so that the selectingr device can hy appropriate movements thereof he placed in position to actuate anv one of the several dogs. n each operative position ot the selecting.,r device when one of the cams is in operative relation to the coii)erationdog, another of the cams will he located in the vertical planeofv another dog.y hat hy reason of the described staggered arrangement of the dogs and cams, only one dog can he operated when the dog-carrier is rocked in arriv operative position of the selecting device. The described staggered arrangement of the dogs and cams is desirable as it reduces the length of the selecting device and the distance which the selecting device has to he moved to operate the several dogsahout one half and makes possible a nmch more compact construction. The. selecting device is adapted to he moved to a neutral or inoperative position hetwecn cach two ot' its operative positions. in which all "of the cams l1-3f are out of' the vertical planes of the reduced endsl of the dogs so as not to operate. any of the dogs if the dog-carrier is rocked while the selecting' device is in such neutral position.v I

Fig. l shows the normal position of the dog-carrii r and dogs; Fig. 5 shows the position thereof when the dog-carrier hasheen swung dmijnwardly and the first dog 13 engaged with the rst gear shifting; wheel 7.

and Fig. 6 shows the position ofthe parts when the dog-carrier has been returned and has turned the first gear shifting wheel.

Figs. 16 and 17 show the second gear shifting wheel and its dog in positions corresponding to those shown in Figs. 5 and 6, respectively.

'The selecting device is shifted to place it in its several operative and neutral positions by suitable operating means which are preferably such. that the selecting device is operated by a handle or lever which is mounted on the steering column where it can be readily reached and moved by the driver without removing his hands from the steering wheel. As shown, the'slide bar 38 lwhich carries the selecting device 30 is provided at one end with rack teeth 41, see Figs. 14 and r15, which mesh with a pinion 42 which is secured to-a shaft 43 journaled in a suitable bearing 44 inthe upper portion of a divided box 45 which is detachably secured to the adjacent side of the casing 4 and serves to inclose the rack arid pinion.. A rock arm 46 is secured to the upper end of the shaft43'and connected by a rod 47 and a rock arm 48 to a shaft 49 which is journaled in a suitable bearing supported on the engine casing at the base of the steer- 30 ing column and is connected by a` pair of bevel gears 50 to a shaft 51 which extends axially through the steering column and is provided :lat its upper end with an operating handle or lever The outer end of this handle 52 preferably swings adjacent to an arcshaped plate or quadrant 53 whiehis secured to the steering column and is provided with suitable indicia to indicate the several posi tions of the selecting device. Thus by moving the handle 52/to the reverse, first, second or third speed position indicated on the quadrant 53, the selecting device 30 is correspondingly moved and placed in position for actuating the dog of thecorresponding gear shifting wheel. Between each two of the four operative positions are indicated on the quadrant neutral positions, and by moving the handle 52. to any one of these neutral positions the selecting device will be moved to one of its several neutral or. inoperative positions. Any other suitable operative connections from the selecting device, 3() to an operating member on the steering post or located inother convenient posi-v tion could be used.

54, 55, 56 and 57 represent toothed racks which are arranged to mesh with the teeth of the gear shiftingwheels 7, 8, 9, 10, respectively. The rack 54, is arranged above and meshes with`the teeth at the upper side ot' the wheel 7 and the rack 55 is arranged below and meshes with the teeth at the nunder side of the next wheel 8, these two racks being connected or formed on the two '65 legs of a U-shaped piece which straddles the 4and the other double rack 56-57 is opera- 'two gear shifting wheels in the same d1- l tion to produce each of shaft 5 and gear shifting wheels with its two legs in the respective planes of the wheels.- The other pair of racks 56 and 57 are similarly joined in a U-shaped piece and arranged respectively above and below and meshing with the other gear shifting wheels 9 and 10. The first double rack 54-55 is operatively connected to one of the gear shifting rods, as 2, of the change speed gear,

tively connected to the other gear shifting rod 1. lf the gear shifting wheel 7 'is turned in one direction by its coperating dog 13 the double rack 54-55 will move in one direc tion and move the shifting rod 2 in one direction, whereas if the second gear shifting wheel 8 is turned in the same directionv the double rack 5455 will be moved in f the opposite direction and cause the opposite movement of the shifting rod 2. In a similarmanner if the gear shifting wheel 9 is turned in one direction it will move the other double rack 56%57 andthe shifting rod 1 in one directiom and if the fourth wheel 10 is turned in the same direction it will cause an opposite movement 'of the double' rack 5(3-57 and an opposite Inovement of the gear shifting rod 1. Thus one of the shifting rods 1 and 2 is adapted to be moved in opposite directions by movements of two of the gear shifting Wheels in onev and the same direction, and the other shifting rod is adapted te be moved in opposite directions by movements o'f the other rection. In other words, thegear shifting wheels are turned in the same directhe opposite movements of the shitting rods. The 'aeks 544-55 'and 56-57 can be operatively connected to the shifting rods in any suit*- able way. As shown, the rack 54,--55 is pivoted to a lever 58 which is fulerumed at its upper end at 59 in theeasing 4 and has a rounded lower end extendingtl'lo yinto a seat in a collar or Dart 60 secured to the shifting rod 2. The other rack 56-57 is simllallyfpivoted to a lever 61 which is suitably fulcrumed at its upper end at 62 in the casing 4 and has a rounded 11|t lower end extending into a seat in a collar or part G3 secured to the other shifting rod'l. Figs. G and 17 show, respectively, the opposite movements of the rack 54-55 andy lever 58 produced by turning the wheels 7 120 and 8 respectively in the same direction.

The shaft 5 and dog- -arrier 12 are rockedv for turning the gear shifting wheel after the selecting device has been set by suitable actuating rier is actuated 'through the medium of the clutch operating pedal and spring 'ofthe vehicle so that when 'the pedal is depressed to release the clutch in the usual manner the dog-carrier 12 is lowercd'to place one 130 means.

In the construction shown7 the clutch operating pedal is' secured to the usual rock shaft 6l which is operatively connected with the `vehicle clutch. This shaft extends transversely through and is suitably journaled in the change speed gear casing A and is provided at one end with a rock arin G5, see Figs. 2, 3 and lS-Ql, which is connected by an adjustable link (3G to an arm or lever G7 which is suitably f'iilerunied at`68 on the easing l. This lever 67 is pi'ovided with a laterally projectingstud or roller G9 which extends into a slot 70 in an arin 71 secured to one end of the rock shaft 5. Then the clutch )edal is depressed the arm 65 and lever 6l? are raised` thereby swinging' the arin 71-upwardl1v and lowering the dog' carrier 12 to the position shown in Fig. C, in which one of the dogs lil-1G is adapted to engage the cooperating gear shifting wheel. lVhen the pedal is released it is returned by the usual spring (not shown) and swings the dog-carrier upwardly and turns the gear shifting' wheel. The arm 7]. is preferably provided with a face 72 which is' curved eoneentrically with tlie'fulcrunz of the lever (3T and lorms a continuation of the lower side ot' the slot in the arm 71, so that when the clutch pedal is raised and the dog-carrier has been raised .to the limit ot' its movement, the clutch pedal and the lever Gl' can continue 'their' inoveinent to insure the proper operation of. the eluteh, the .stud acting' as 'a lock to prevent the movement ot the dogcai'i'ier and Prear shifting mechanism while the clutch isv inaction. 73 indicates an adjustable screw or stop for engaging the arm 71 to limitl the downward movement of the dog-carrier. 74. represents a spring which acts .on the llever aria f3.3 in conjuagtion withv lthe usual clutch spring tor -producing the a'ear shitting' action ot the ineclninisin: This spring;i could, it desired, begnade to entirely relieve the cluteh spring er it can be omitted and the elute` aie-ne or other suitable, spring' used.

collar or ring is loosely sleeved on the shaft 5 at one side of each of the gea-r shifting wheels 7-10 The locking rings serve 'to eparate or space apart the gear shitting wheels. rlhe locking rings are held from turning with the shaft by suitable means7 such 1to1' instance, as a finger H1 projecting` from each ring into a socket S2 in the top of the casing el, and each of the rings is provided with a radially projecting' arm or part 83 provided at the side thereof facing the adjacent gear shifting wheel with ribs 8l which are curved con'- ceiitrically with 'the shaft 5. The bolt 20 of each of the dogs 1316 is provided with a finger which extends at on'e side of the col'iperating gear shifting wheel and is provided with correspondiugly curved ribs which are adapted to interlock with the lribs Sl on the locking' ring. `When one of the dogs has been inovcd b v its selecting cani into the notch 11 inthe cooperating ,Qear shittniacr wheel and the dog-carrier 12 is swung' upwardly to turn the wheel, the.

This moves the selecting device 30, as explained, to a position to place the cam 32 in opcrativerelation to the 'gear operating dog 14. The clutch pedal is then depressed and released and this causes the operation of the dog-carrier 1Q to cause the dog 14 to'engage and turn the gear shitting wheel S in the manner described. The .rotas tion o't this wheel moves the rack Fil-55 and the gear shifting rod 2, thereby placingthe lirst forward speed gear train in action. The diiver can then change to any other desired gear by tirst shitting the selecting lever 52 to the required point indicated and again operating the clutch pedal in a similar.

manner which will anse the operation of the required one of the gear shitting wheels 710 and produce the desired gear change. After setting the selecting lever 52 tor a desired speed, it can be changed back to a neutral position or any other gear changing position before the clutch pedal is actuated withoutI atl'ecting any change in the mechanism other than the shitting ot the selecting device SO. The pedal can be operated to release and apply the clutch at will while any speed gear is in action without,- changing the gearing, provided the selecting lever is not changed in the manner before explained.
