Be it known that 1, CHARLES a citizen'of the United States, and a resident of Bar Harbor, in the county of Hancock and State of Maine, have invented a new and Improved Selective Controlling Mechanis Of which the following is a full", clear, and exact description. w

The invention relates to selective controlling devices for automobiles and other m'otor vehicles and machines, andthe object'of the invention is to provide a new and improved selective controlling mechanism arranged to enable the operator in charge of the machine to readily actuate the gear shifting mechanism or the brake mechanisms or other devices through the agency of a single pedal, thus leaving thepperators hands free for other work. Another object is to hold the selective controlling mechanism in the selected position on the operator removing the foot from the pedal. Another object is to permit of applying the selective controlling mechanism to devices to be actuated without requiring altering of the construction of such devices.

With these and other objects in view, the.

invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in' the claims.

. A practical embodiment of the invention is represented in the accompanying draw- Fig. 3 is an enlarged plan view of the pedal with parts shown insection; Fig.4 is a cross section of theselective controlling mechanism on the 'line' l4 of" Fig. 5 is a side elevation of the selective controlling mechanism arranged for actuating the gear set of a Ford automobile, parts being shown in section;

Fig. 6 is a sectional plan V16W'0'f the same Fig. 7 is a plan view of the selective controlllng mechanism arranged for actuating the service and emergency brakesof an auto-' mobile and F. Mans'ron,

' Fig. 8 is a sectional side elevationof a trolling mechanism shown in Figs. 1, 2 and 3 is mounted to swing up and down and to slide sidewise on a pivot 11 held on the outer ends of cylindrical casings 12 (see Fig.3) attached toarms 13 on a head 14 secured on the upper end of a stem'or a post 15. On thepivot 11 are coiled two springs 16ers tending into the casings 12 and pressing opposite sides of the pedal 10 to normally hold the latter in a central position, that is, approximately midway between the casings 12, but to allow of shifting the pedal sidewise either to the right or to the left or to .swingthe pedal up or down. In order to facilitate the sidewise movement of the pedal 10, the latter is providednear its for.- ward end with side flanges 17 and 18 adapted to be engaged by the "sides of the foot of pedal 10 is also provided at its rear end with a heel rest 1.9 to permit of conveniently rocking the pedal in an up and down direction.

On the head 1 1 is arranged a set screw 20 to limit thedownward rocking movement of the pedal 10. The stem 15 extends throughan opening 25 arranged in the floor 26 of theautomobile and the lower end of the stem 15 is adjustably secured in the split end 27 of a swing- 1 g-support 28 by'the use of a clamping screw 29, as plainly indicated in Figs. 1 and 2. The support 28 is provided with two side members 29 and 30 mounted to swing' at their free, ends on a. transverse rod 31' attached to the chassis of the automobile to permit the support 28 to swing up and down thus carrying the main pedal 10 bodily with it. From the'foregoing it will be seen that by the arrangement described, thepe'dal10 has an up and'down swinging movement on the pivot '11,'can be shifted sidewise on the pivot to the right or to the left, and moved bodily up and down with the swinging sup port 28.

From the under side of the pedal 10 dc l pends an integral arm 40 having its lower end 41 rounded ofii' and'adapted to engage either one of the bearings 42, 43', 4Aor 4E5 formed on top of selective members 46,47,

48 and 49,.arranged one alongside the other and inoiuited to slide forward and backward in a recess 50 formed in the top of the support28. Each of the bearings 42, '48, 44 and 45 is rounded off at the front and back (see Fig; 2)'to hold the pedal arm 40 against accidental 'sidewise shifting liable to be caused'by the action ofthe springs 16 in case either is compressed at the time the pedal is shifted from a central position to either the right or left. Each of the selective members 46, 47, 48, 49 is provided with a rearwardly extending pin 51 having a head 52 slidably engaging a recess 53 formed in a bolt 54, and the head 52 is pressed on by a spring 55 arranged in the recess 53 and bearing against the rear end wall of the said recess to yieldingly hold the bolt 54 on the pin 51. The bolts 54 of the several selective members 46, 47, 48 and 49 are adapted to engage keepers 60 formed in the heads 61 of actuating members 62, 63, 64 and 65 arranged one alongside the other, and between thesidearms 29 and 30 of the support 28. The rear ends of the actuating . members 62, 63, 64 and 65 are mounted to gage friction rollers 70 and 71 journaled on speed gear-of the gear set,

the upper end of a lever 72 mounted to rock on a rod 78 attached to thechassis of the automobile. The lever 72 is connected with a link 74 connected with the device onwhich the selective controlling mechanism is used.

7 The cams 68 and 69 are disposed in opposite directions and are adapted to engage friction rollers 75 and 76 journaled on the upper end of a lever 77 mounted to rock on the rod 73 and connected by a link 78 with the device on which the selective controlling mechanism is used and in which a change is to be efi'ected, In case the selective controlling mechanism is used on'an automobile, the actuating member 62 controls the high member'63 controls'the first speed, the actuating member 64- controls the second speed, and the actuating member 65 controls vthe reversing mechanism. Itwill be noticed that the cams 66 and 68 arearranged to impart a forward swinging movement to the levers 72 and 77 on swlnging the actuating members 62 and 64 downward, and the cams and 67 and 69 are so arranged that a rearward swinging movement is given to the levers 72 on swinging the actuating members and downward. It is understood that the actuating members 62, 63, 64 and65 together' with their cams-66, '67, 68 and 69 form swinging cam arms adapted to actuatethe levers 72 and 77, as above explained,

the actuating The arm of the pedal 10 is provided with a spring 85 bearing-with its free end ona transversely extending rod 86 held on a cover 87 fastened to the top of the support 28 and extending across theselective members so as to hold the same against upward movement in the recess 50 in which the selective members are mounted to slide, as previously explained. A set screw 88 mounted on the arm 40 engages the spring 85 'to permit of adjusting the tension of the said spring; It will be noticed that when the pedal 10 is shifted sidewise, the arm 40 and the spring 85 move with it, and the free end of the spring 85 slides transversely on the rod 86. The spring 85 holds the pedal 10 normally in uppermost position as shown in Fig. 1. The cover 87 is provided at its forward edge with forks or guideways 89 into which the lower end (if the arm 40 is adapted to ass on swinging the pedal 10 downward tlius holding the arm 40 against accidental sidewise movement as long, as the pedal is pressed down.

One of the side arms 29 or 30 of the support 28 is provided at its fulcrum end with an angular arm 90 connected by a link 91 with the throw-out clutch mechanism to throw out the clutch whenever the support 28 is swung downward, as previously eX- plained. Thus the throw-out clutch is actuated immediately prior to a change in the device on which the selective controlling mechanism is used. It will also be noticed that the-usual spring 'of this clutch causes the support 28 to return to normal upper; most position when releasing the downward pressure on the support.

In order to prevent accidental sidewise shifting of the arm 40 and its pedal 10 during the time the support 28 swings down and up, or an actuating member-62, 63, 64 or 65 is down in selective position, the following arrangement is made: Each of the heads 61 of the actuating members 62, 63, 64, 65 is provided with a double cam 95 engaged by a friction roller"96 journaled on a bar 97 mounted to slide in a bearing 98 attached to the under side of the support 28. The bar 97 is pressed rearwardly by a spring 99 to hold the correspondin friction roller 96 in engagement with the corresponding cam 95. Each of the bars 97 is pivotally connected with a locking arm 100 fulcrumed at its lower end at 101 on the support 28, and each locking arm 100 is provided with a rearwardly extending locking fork 102 normally out of the path of the arm '40 but adapted to engage the said arm 40 on swinging the support 28 downward owing'to the friction ,roller 96 traveling down on the '.lower portion of the double cam 95. It is understoodthat whenever ,the support 28 is swung downward, as "previously explained, and one of the actuatlng members 62, 63, 64

y or 65 is carried along then the friction rollers actuating members remaining in uppermost 96, in engagement with the cams 95 on the arms 100 areswung rearwardlyand their .forks 102: move into the .path of the arm 40 thus pretenting s'idewise shifting ofthe arm 40 and consequently ofthe .pedal- 10. During the: return movement of the support and while the selective actuating member re-- mains in lowermost position, the friction roller 96 of this actuating member travels on the upper portion of its cam 95 and hence the corresponding locking member 100 is caused to swing rearward-so that its fork engages the arm 40 and locks. the same against sidewise movement. It is understood that during the return movement of :the support 28 the friction rollers 96 of the non-selective members reengage their cams ing in lowermost position.

and swing the locking members 100 forward out of the path of the arm 40 which latter, however, is held locked by the other fork controlled by the selective member remain- In order to move the arm 40 into engagement with the selective member 49 for the 7 reverse actuating member 65, it is hecessary for the operatorto actuate an auxiliary or supplemental pedal 110 arranged alongside the flange 17 of the main pedal 10. The auxiliary pedal 110 is mounted to swing loosely on the rod 11 as the fulcrum, and is.

pivotally connected by a link 11-1 with "a lever 112 fulcrumed at 113 near the lower end of the pedal arm 40. A spring 114 connects the arm 40 with the lever 112 to normally hold the free end of this lever 112 in engagement with'one side of a 'lug 115 arranged on thetop of the plate 87 intermediate the selective members 48 and 49. As.-

the lever-112 is mounted on the pedal arm 40 it is evident that the latter cannot be shifted sidewise into engagement with the selective member 49 until the lever 112 is swung upward out of engagement with the lug 115 on, pressing the auxiliary pedal 110. From the'foregoing it will be seen that by the arrangement described the pedal arm 40 cannot be'moved into engagement'with the selective member 49 for the reversing mecha- Y nismunless the auxiliarypedal 110, is'first pressed prior to shifting the ma n pedal 10 sidc'wisefrom the left'to theright;

The operation is as follows:

When the several parts are in the position shown in Fig. 1 then the automobile is running at high speed owing to the actuating member 62 bemg in lowermost position, and the other members 63, 64 and 65 as well as the support 28 being in uppermost posiv tion. Now when it is desired to change to,

say, second. speed then the operator swings the 'pedal down and bears down on it ,to impart a downward swinging movementto the support 28 whereby the arm -90 and the link 91 release the clutch. On swinging the pedal 10 downward, as above mentioned, the selective member 46 is caused to slide rear Iward by theaction of the pedal arm 40 and ing member 62 'touppermost position; It is understood that the tension of *the spring for returning the support 28 is greater than that of the spring 85. During this return movement of the actuating member 62, its cam 66 acts on the friction'roller 7 0 and thus allows the lever? 2 to return to normal neutral position thereby throwing out the high speed gear and leaving the gear set in neutral position. The pedal 10, is now released to permit it to return to normal uppermost position by the action of its spring 85 thus unlocking the actuating-member62 by withdrawing the bolt 54 of the selective member 46 from the keeper 60 of the actuating mem ber 62. The pedal 10 is now shifted side- -wise until the arm 40 engages the selective of the actuating member 64. Then the op erator bears down on the pedal to swing the supper-152,8 downward, and in doing so the selective actuating member 64 .is carried along, whereby its cam 68 acts on the fricf tion roller 7 5 andthe lever 7 7 to throw the second speed gear of the gear set into action.

The operator next. allows the pedal 10 to 'swingupward to disengage the bolt 54 of.

the selective member 48 from the keeper 601 of the actuating member 64, and then the f operator allows the support 28 to return to uppermost position with the actuating member 64, however, left in lowermostposition.

'VVhen it-isfdesired now to change from second speed to reverse then the pedal 10 is swung downward and pressed to swing the support 28 downwardwhereby the shot-out bolt 54 of the selective member 48 snaps into the keeper of the actuating member 64 to return the latter to uppermost \position on re turning the support 28 and the pedal 10 to their uppermost positions. The pedal 10 is now released thus unlocking the actuating .member Gaby withdrawingthe bolt 54 of the selective member 48 from the keeper 60 of the actuating member 64. On returning the actuating member 64, its cam 68 acts on the friction roller 77, thus imparting a return swinging movement to the lever 77 whereby the second speed is thrown out of action and the gear set is returned to neutral position. The operator now presses on the auxiliary pedal 110 to swing the lever 112'out of engagement with the lug 115 and then the operator shifts the pedal 10 farther to the right until the arm 40 engages the selective member 49. The above described op-.

eration is then repeated, that is, the pedal 10 is swung downward to move the selective member 49 rearward to engage the bolt 54 thereof with the keeper 60 of the actuating member 65, andthe support 28 is now swung downward and with it the actuatingmember 65 which by its cam 69 acting on the friction roller 76 actuates the lever 77 thus throwing the reversing gear-of the gear set into action.

lVhen the selective controlling mechanism is used on the gear set of a Ford automobile see Figs. 5 and'6) then the arm 40 of the pedal 10 's adapted to engage three selective members 200, 201, 203 having spring-pressed bolts 204 adapted to engage keepers 205 on the free ends ofactuating member 206, 207

and 208 mounted to swing on the rod 31 on which the support 28 is mounted to swing up and down. The actuating member 206 controls the high gear of the gear set, the actuating member 208 controls the low speed and the actuating member 207 controls the reversing mechanism. The actuating members 206 and 208' are provided with cams 210 and 211, while the actuating member 207 is provided at its fulcrum end with an angular arm 212 connected by a link 213 with the reversing mechanism 21 to actuate the same. The-cams 210 and 211 engage friction rollers 220 and 221 journaled on arms 222 and 223 secured to the high speed clutch shaft 224 connected by an arm 225 and link 226 with the low speed clutch 227. The sup port 28 is normally held in uppermost position by a spring 230 connected with an angular arm 231 on the fulcrum end of the support 28.

The operation is as follows Normally the high speed gear is in action (see Fig. '5) and when it is desired to change to neutral position, it is only necessary to press the pedal 10 downward to actuate the selective member 200 and to engage the bolt 2041 thereof with the keeper 205 of the high gear actuating member-206. On bearing down on the pedal 10 a downward'swinging movement is given to the support 28 thus carryingthe high speed actuatinginemher 206 along to, shift the gear set to neutral position. The operator new releases the 28. is swung downward into the actuating member .bearing on the in lowermost position and to allow the support 28 toreturn to uppermost position. When it is desired to throw in the low gear, the pedal 10 is shifted sidewise to engage the arm 40 with the selective member 203 and then the pedal is swung downward to cause the selective member 203 to be shifted rearwardly to engage its bolt 204; with the keeper 205 of the actuating lever 208. The operator then bears down on the pedal 10 to swing the support 28 downward thus carrying the actuating member 208 along and thereby moving thegear-set into low speed position. The operator now releases the pedal 10 to withdraw the bolt 20 1 of the selective member 203 from the actuating member 208 to leave the latter in lowermost position whileallowing the support 28'to return to uppermost position.- r v 1 When the gear set is in high gear position.v and it is desired to go to low speed position, then it is only necessary for the operator to shift the pedal 10 sidewise to engage the arm 40 with the selective member 203 and then the operator swings the pedal 10 downward to lock the selective member 203 to the actuating member 208, and then the support lowermost position with the actuating m'ember 208 and the latter is left-there on releasing the pedal 10 and disengaging the selective member 203 from the actuating member 208. When running in low gear and desiring to change to high gear, it is only necessary'to press down the pedal 10 to pick up the actuating member 208 and to return it touppermost position thus going automatically into high gear. When using the selective controlling mechanismfor controlling the service brake and the'emergency brake of'an automobile, for

The support 28 is provided with an angular arm .305 connected bya link 306 with the service brake so that when the support 28 is swung downward by the operator pedal 10 then the service brake is=applied. When the pressure on the pedal is released, the support 28 remains normally in uppermost position thus releasing the service brake.

The actuating member 303 is provided at its under side with a cam 310 a friction roller 311 journaled on a lever 312 connected by a link 313 with the emergency adapted to engage neoapee brake to actuate the latter -onswinging the actuating member 308 downward at the time the arm 40 of the pedal is in engagement with the selective member 300 and has actutime the arm 40 is in the position'shown in.
