- Specification of Letters Patent. Pmtcgmtedl Dgqg 14L 1915 Application filed August 21, 1913. Serial No. 785,846.

To all whom it may concern Be it known that T, STEPHEN I. FEKETE,

a citizen of the United States, residing at' enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to shifting devicesarm at the steering wheel, so that the desired adjustment I of the change speed gearing shall be automatically obtained on the movement of a part,'in this instance the 'clutch lever. T secure this object in the device illustrated in the accompanying drawings, in which, I I

of the steering post 0.

e is the casing for the change speed gearmg.

7 is the clutch shifting. lever having the pedal 72. at its upper end.

k 71, indicate different positions of the pedal h, corresponding to different positions of the lever f. The clutch lever f is pivoted at g.

7c is a lug extending downward from the pivoted end of the lever f. i

z 2' is a casing secured to the side and toward one end of the casing 6 so as to pro-.

trude beyond the right hand end of said casing as shown in Fig. 4.

u is a bearing surrounding an aperture passing through one end of the casing 2' i.

s is a rod adapted to reciprocate through the aperture in the bearing a. The rod 8 is provided with fins t which fit into slots in the walls of said bearing and prevent any relative angular motion of the rod s. Said rod is interposed in the line of travel of the lug is so that if the lever f is turned about the pivot 9, it will first come into contactv with the rod 8 and then press said rod into the casing i 2".

m m indicate rods by which the gear wheels of the change speed gearing are shifted to provide theadjustments for the difierent speed ratios. The gear wheels and shifting rods are of an ordinary form and need not be particularly described. They are illustrated in Fig. 10 and the relative position of the shifting mechanism thereto is shown. The rods mm. are forked, as indicated at 14 in Figs. 4 and 9 to engage over the circular cams 13 upon the ends of the shifting lever hereinafter described.

6 is a lug extending inward from the wall of the casing z i which is opposite to the wall through which reciprocates the rod 8.

n n are shifting levers pivoted in parallel outer ends which engage the forks 14 of,the

rods mm. vTheshifting lever a is provided with a lug upon one side or its pivot and l .upon the other side; and the lever a is pro- ;vided withcorrespondlng lugs 5 on opposite sides or" its pivot.

m is an arm integral with the lever and extending first at right angles to the arms thereof midway between the ends of the lever to w then bending outward as shown in Fig. 4 and extending along the outer wall of the casing i,

y, is a lug extending outward from the outer end of the arm wand engaging ina slot 11 ill-a wall or portion of the casing i i. The slot 11 branches at its end farthest from the rod 8 upward into a branch 11 and downward into a branch 11". The rods 0* 1' bear at their ends opposite .to those upon which are. fixed the gear wheels 2 2 upon the outer ends of the lever arms w w and are held thereagainst by the springs Q, .g. z is a gear wheel secured to the end of the rod 1' remote from'the lever to 'w and 2 is a slmilar gear wheel similarly located upon. the-end of the rod 7 I 2, is an annular cam extending from the free face of the wheel a, concentric there-.

with, and 3 is a similar cam so extending from the gear wheel .2 The teeth of the

gear wheels

2 and 2 engage with each other so that-they shall have proportionate angular movements. I 12 and 20 areslots in the

annular cam

2, and 21 and 22 are slots. in the cam 3. These 40 slots have a definite angular position about as indicated in Figs. 6 and 7 of the drawmgs. The annular cams 2 bear against the lugs 4, 4= to hold the lever n. in a position approximately parallel to the face of said cam and to hold the corresponding shifting rod m in the position in which its gear wheels are disengaged; the annular cams3 bear against the

lugs

5 and 5 to hold the arm n in a corresponding position and the other shifting mechanism in its neutral posi tion. If a slot in the annular cam 2 comes opposite one of the lugs 4 or 4? the other of said lugs will be in position to bear agalnst the cam andthe lever 11. will'be 1 brought by the movement of the gear wheel 2 toward said lever, into a position slant mg toward said gear wheel upon. the side where the lug cut away portion. The lever arm a may be oscillated in the way just described with reference to the arm n. This is illustrated in FFi s in which it will be seen that the lug 5 on the lever arm n is opposite the slot 22, the lug'5? being upon the outer surface of the cam 3. The movement of the wheel 2 adjusted throu h the rod .18,. gear wheels comes opposite the slot or- .said wheel would oscillate the lever n in the oposite direction.

, 10, is a gear wheel having a broad face, its teeth engaging the teeth of the gear wheel 2 (Fig. 3). i

'7 is the shaft upon which the gear wheel. 10 is keyed. The shaft 7 rests in bearing .8 in a casing 9 which incloses the wheel 10 and communicates with the casing 11 i. The shaft 7 (Fig. 1) passes to a position adjacent to the lower end ofthe steering post 0 and at this end is provided with a beveled gear wheel 15.

16, is a A ,eveled gear wheel, its'teeth engag- 9 ing the teethof the gearwheel 15. The beveled gear wheel 16 is secured to the lower .end of a shaft 18 which extends through the steering post 0 and is provided at its upper end with a lever arm 17 ada pt'ed to pass over 5 a quadrant 19 upon which are placed the indications of thevarious change speed gear adjustments; thus N'stands for neutral, L

for low speed, I for intermediate speed, H for high speed and R for reverse.

The operation of the above described device is as'follows: If the'lever .17 is turned to the position shown in Fig. 2 registering with the letter N the gear wheels .2 z? are 103 16 and 15, rod and gear wheel 10 so that the cams 3and 2 are in positions inwhich lthe elevated portions of the cams are opposite the lugsfi, 4, 5 and'5i as shown in Fig.

6, and when the clutch lever It is pressed downward the rod sis pressed in forcing the lever arms w 'w against the ends of the rod r andr pressing said rods. toward the levers n n and thus forcing said levers into position approximately parallel to the faces of said wheels (Fig. 4:). which corresponds to the neutral position of the change speed gearing. If the lever: 17 is turned to register with the letter L on the quadrant 19 the

gear wheels

2 and 2 are turned through the mechanism above describeduntil. the slot 22 is opposite the lug 5, on the lever n Now if the clutch lever k is oscillated, the rod 8 is-forced inwardas before forcing the rods 1", 4" forward. The'teeth of the gear wheel 10 and the lever arm 'n? are rocked to the position shown in Fig. 9 thus drawing out the gear shifting rod. m with which it engages and throwing inthe'low speed gearing adjustment. In this movement and in the other movements in which the lever arm n or the lever arm n is oscillated the lever to 'w is turned about the pivot 12 as indicated in dotted lines in Fig. 5. During the first part of the travel of the rod 8 the plug y moves in the slot 11 and holds the arm as in its intermediate position. During the latter part oftravel of said rod when one of the levers n or n is being oscillated the aboutits pivot 'v and the lug 3 is brought into one of the branches 11 or 11 of the slot 11 and engages against the wall of said slot, as shown in Fig. 5.

The manipulation of the speeds and the reverse will be obvious from the above description. When the gear Wheels 2 a are turned so that the slot 12 comes opposite the lug 4 the lever arm n is oscillated to produce the intermediate adjustment of the change speed gearing. When the slot 20 comes opposite the lug 45* said lever is oscillated in the opposite direction to produce the high speed adjustment andwhen the slot 21 comes opposite the lug 5 the lever n is oscillated to secure the adjustment for reverse motion;

Tt will be observed that in the above described apparatus when the gearing is moved to its neutral position the rods r and r move at an equal speed and the action is direct and when a gear is moved into engagement with another gear one of said rods is held stationary and the other is moved.

The pivotal point of the integral lever arms w to changing from the center in the first case to the end of one of said arms in the second case and the power being .applied half way between the ends of said arms so that the speed of the moving part is doubled, thus securing prompt engagement and a greater leverage to overcome the frictional resistance to disengagement.
