SEIIJECTIVE LEVER'.

- Ne. essaie.'

.To au www a may 6.5mm, l Beit known that We, THOMAS W. WARNER land FRANK H. Jones, citizens of theUnited at Muncie, 4in thel county of Delaware andv tate of Indiana, have invented certain new and useful Improvements in Selective Levers, of which the fllowing is a. ,I specification. i ,()ur present invention relates to that class bf, shifting levers, principally used in auto- .mobile construction, by

means of which either of a plurality of sub-levers may be p- ;erated from `a single main operating lever.

A Said invention consists'in' certain improvements 1n the constructlon and arrangement of arts 'of a device of thls character, as will Referring to thev drawi s, which are made apart hereof, and on Whic `similar reference characters indicate similar par-ts, Figure 1 is la side elevation of a structure of the charac- .ter in question, assembled ready Ytobe a plied to the machine upon which it is' to e `lsed; Fig. 2 a central vertical sectional view thereof, some parts, however, bein shown in elevation for pur oses of better i ustration; Fi 3 a sectlona view lookin toward the le t from the dotted line 3 3 in ig. 2; Fig. 4 a view looking toward the right from the dotted line 4 4 in Fig. 2, the position ofthe main lever .bei-ng indicated b means of ldotted. lines; Fig.. 5 ay sectiona viewwhen looking in the' direction indicated by the ar# rows from dotted line 5 `5 inl Fig. 2; Fig. 6 a

2, and Fig. 8 a view similar to la Fig. 2, but on an enlarged scale s alternative construction. 1

In said drawings the part marked 21 is an lportion of owlng an ordinary brake-shaft, and it carries on its end a brake-lever 22. As theseparts are not features of our resent invention they will not be further ascribed herein except ilci- 31 leading to oneelement of a reverslng gear (not shown)l or such like device to be o erated, and surrounding this sleeve-shaft 1s 'a second sleeve-shaft 41 leading to another ele-I ment 'of such reversing gear or mechanismto Patented Apr-'n 2e, 190e.

be operated. These several shafts, thus `sleeved together, rest in a bearing in or adj acent to a stationar uadrant-structure 51j, which is securely holte or otherwise fastened to the machine with which our improved selective lever is to operate.

Uv on the sleeve shaft 31 a sub-lever 32 is y attached. In the upper end of this r1 siii-lever isa slot, and within said slot is a 4 rlug 33 which is carried by the s ring arm or spring-actuated' arm 34. n This u 33 has a projecting point 33 which normal y extends into and engages with a notch in a flange on the structure 51, as will be presently described. The sleeve-shaft 41 has a sub-lever 42 rigidly secured thereto, and in its upper end it has a slot in which is mounted a lug 43 carried by a spring-actuated arm 34, and hav ing a projectmg point 43 which is adapted, like the point 33', to engage with a notch in a flange on the stationary part 51,V as' will be presently described. As will be readily, observed, the arrangement of these lu s, spring arms, and notches is such lthat subevers 32l and 42 are locked in their upright positions except when forcibly moved therefrom.

or otherwise rigidly secured to the machine. It embodies a segmental plate 52, having, as is'best shown in Fi 6, a central lar e slot or opening, and this s otvor opening is 'ou'nded on its two longer sides by the depending flanges 53 and 54. These lflanges, as best shown in Figs. 3 Aand 4, have the central" notches (already referredto) withv which the projecting points 33 and 43 are adapted tol engage, whereby the sub-levers are lockedin their upright position.

The mam lever 61, is (pivotally mounted on a rin loosely mounts on the sleeve-shaft 31--t e lower end of said main lever being forked, and ysecured to said rin bv a pivot 63, as 1s best shown'in Fig. 3. aid ring has an extension containin a hole to receive the pivot, and the pivot 1s located below the shafts, on the opposite side thereof from the oint wherek the main leverr and the sub- 'eveis engage, thus decreasing the necessary The structure 51, as b fore stated, is bolted sideway movement of the handle end of the Imain lever Without increasing the length of the sub-levers and the sizeof t quadrant structure. This mainV lever 61 lxtends up through the large` slot or opening kin .the segmental plate 52, and terminates 1n 'a suitable handle by means of which it can coiiveniently be operated. At a point opposite the spring-actuated lugs 33 and 43, this lever has projections 64 and 65. These projections, as is clearly shown in Fig. 2, :ire olf such torni and character that when the lever 61 occupies a central position in the large slot or opening in the segmental plate 52 the said projections will have no effect upon tht` lugs 33 and 43, but said lugs will remain in engaged position, and the sub-levers will remain locked at that point. The lever 61, however, is capable of being swung sidewise, and, when pushed in 'one direction oi' the other, will disengage the lug against which it is pushed. lf, tor example, the lever 61 is ushed toward the right, the lug 3 will bo orced over until its point 33 is beyond or behind the flange 53. At the same time the lug 65 will follow in the same diiection until it is entirely free of the 'flange 54. Meantime the lug 64 has forced the lug 33 partly out of its slot in sub-lever 32 and has itself become engaged with said slot. When the parts have reached this oint, the main lever 61 and the sub-lever 32 ecoine in el'lect one lever, and, when moved back and forth, will rock the sleeve-shaft 31, to any point within the predetermined limit of movement, at the will of the operator. The point 33 of the lug 33, assoon as the movement in question begins, will pass behind the flange 53, and

can not thereafter escape therefrom until it is brought back to upright position, where said lug-point is again opposite the notch in said flange, when it will rengage therewith unless he d forcibly out of such engagement.

Nhen the lever 61 is .thrown to the left (as the parts are arranged in Fig. 2), the operation is practically the same with respect to the sub-lever 42 and the shaft 41 which it operates as that which has just beendcscribed. The rejection 65, however, differs in one respect om the projection 64. Said projection has an upturned lip 65', which, when the lever 61 is forced over, passes to a oint behind theflange 54. Then, when the ever 61 is swung in one direction or the other, in o erating the sub-lever 42, this upturiied lip, Y eing engaged behind the flange 54, prevents the lever 6.1 from being moved sidewise until its return to its middle or upright osition. Likewise, when this main lever is swung to the right, and so engaged with or operating the sub-lever 32, this upturned' lip 65 will, when the lever is swung to one side or the other of its u right osition, bear against the adjacent side of t e ange 54, and it thus serves also to hold the main lever into its engaged or operative position with the sub-lever 32. The subelevers are thus bott;- iield to their middle position et all timesy except when the main lever has been moved sidewise the full distance provided for b the construction and thus fu ly engaged wit i one of them, when the one so engaged can be swung back and forth as desired, the

other, meanwhile, being securely locked in place. All movements of these levers and the attached mechanism except such as purposely otlected bythe operative are ellcctu#- ally precluded.

As will be observed, there is formed on the segmental plate 52, on one side of the slot or opening therein, a detcnt 71. A pawl 72 is pivotally mounted on the lever 61, and a push rod T3 extends upwardly into and through the handle portion of said lever, terminating in a knob Tat. .A spring 75 exerts a pulling torce on the rod 73, and normally holds the pawl 72 into engagement. lt may be disengaged, when desired, by simply pushing down on the knob Tft. The purpose of this is to prevent the lever from being ordinarily so moved as to cause the gear controlled by this leverr to be thrown to the reverse position. .-'llie lever can thus be manipulated, at will, l'or any ofthe other movements desired, without any danger of unintentionally reversing the travel of the apparatus being manipulated. When it is desired to reverse the travel of such apparatus, however, it can readily be done by pushing down with the thumb ou the knob 74, and then throwing the lever el over to the reveise position.

ln tho alternative view, Fig. 8, we have shown a little different construction, in which thc lugs in the slots at the upper ends ol the sub-levers, instead of being carried by arms which are in themselves springs, are carried by pivoted arms `134 and 1111- which. are

actuated by springs 135 and 145. The tlanges on tlie segmental section :32 and the projections on the main lover 61 are also somewhat diiicrently arranged, although having the same e'll'ect, and being substantially the same in all essential respects.
