Specification'of Letters Patent. Patented June 13, 1922 Application led November 29, 1920i. Serial No. 427,140.

To ZZ `whom t may conce/m: I

lle it known that l. Gaizirntrr lV, lVoOnwAiio, a citizen oi'f the United States, residing at 5056 lllashington Blvd., Chicago, in the county ot Coolrand State oit Illinois, have invented a new and useful Improvement in Button Blocks, ot which the following is u specification;

This inventionV relates to button blocks and the like and is 'fully described in the "following sigieciijication and shown in the accompanying drawings in which:

AFigure 1 is a plan view ot the button block applied to the steering column ot an automobile lilig. 2 is an enlarged plan view ot theintei-ici' mechanism with the cover removed;`

Fig. 3 is an enlarged vertical section on the line IE5-l of Fig. 1;

Fig. 41 is a partial section on the line fi-Ll 1 and Fig. 5; y 5 is a partialv section on tlieline 5-5 ot Fi el; and I lil t3, T and 8 are partial sections on-the lines GWG, 7-7 and 8-8 ol Fig. 2.

ln the embodiment illustrated7 the button block consists el" a housing having Atop and` bottoni sections l() and 11 respectively, which are secured together hy fnieans ot bolts12. The lower section is clamped to the stationary tube 1B l'orming part oit the steering column and yis supported thereby, above the steering wheel. I i i 1 'llie button block is adapted to be, used with inv automatic shittii'ig mechanism disclosed in my application` Serial No.

zlQ-l. ln this case, however. the wires 15 actas tension members whereas the wires 915% etc., oit my previous application are under compression. The wires 49, (50, Sil, S5, S6 and 87 are tension members and the wires 15 can be connected directly to theseI to obtain the same previous disclosure. The wires 15 pass down through the` tube 16 which is rotatably mounted inthe tube 17 which in turn is rotatably mounted in the tube 13. vThe spark advance lever 18 and the hand throttle control lever 19 are mounted on the tubes 16 and 17 respectively,

and Control. the spark advance and throttle in a well known manner. o

Each of the wires 15 as previously stated, is connected to mechanism which shitts the transmission gears to reverse. neutral, 4first speed, intermediate speed or high speed, and

`pressure is applied to them.

. time. ot the levers 20 to 2Li-A inclusive so that-no two one Ot these wires is connected to mechanism.

ifor applying and releasing the brake. AThese wires are secured lat their upper end by means oit screws 15a to a seriesof levers 20, 21, 23, 2l'and 25 respectively which are pivotally mounted on pins 21 and are drawn downwardly by a series'of springs in the `rear shitting mechanism` (not shown). Plungers 26 are slidably mounted in the upper section oi the housing and have longitudinal guide-ways therein `in which slide pins 27 by which the plungers are prevented trom turning. Buttons 28 are secured to the upper end Oiitliese plungers and each is marked as shown in Figure `1 to designate vthe particular setting of the gears which it controls; R is YFor reverse, N tor neutral, 1 ttor first speedetc.

A plate 2S) issupported above the

levers

20, 21, etc., on posts 3() and has a series of itrictionally mounted thereon by means of screws 82, as to be movable when some y At the sideiot the housing, 'these stops engage abutment 11a fan-like stops 31 which are hingedly but;

and are sovtormed that they will permit but one oi? they lugs 33 `to pass these stops at any One ot the lugs 33 is placed on each ol the levers controlling the gear-shifting mechanism can be Operated at the same time ,lt will be Observed, however, thatl no lug is placed on the lever 25 which controlsqthe brake-operating mechanism as it is desired to be able to `apply the brake at any-time regardless oi the position olE the `gear shifting mechanism. ,f l

The letters and numerals on the buttons 23 are made with radium so to be visible in the darl'and openings 34 are formed in the upper housing section 10 vimmediately in iti-ont ot the controlling neutral and first, second and third speeds. `Above the arcuate plate 29 is secured an arcuate shift 35 having series olf' radium spots 36 therein which lie immediately beneath the openings 34. As

` shown in Figure`2 all of these radium spots 36 are covered except theone infront ot the button which had been last actuated. Thus the position of the transmission gears is lshown at night by means of the radium spot and in the day time the same spot while not luminous is readily visible for the reason that only one will be shownto be uncovered by the members 31. No radium spot .36`is )laced in Vlront oit the reverse button marked l Vlor the reason that they are seldom used and then only for a short time. That the gears are in reverse is indicated by the absence ot the radium spot in any ot' the openings 34.

In order to prevent accidental actuation oi the reverse button, I have provided its plunger 29a with a releasing pin 37 as shown in Figs. l, 4 and 5 which must be pressed inwardly before the button Q8 can be depressed. The pin 3T is slidable in a hole in the upper housing section l() which is at right angles to the hole in which the plunger 529 's slidable, the peripheries ot' these two holes slightly overlapping as shown in Fics. 4and 5. The plunger Q9 has notch 29') which is a continuation of the periphery o't' the hole in which the pin 37 is slidable when the plunger 292L is at the top ol: its throw. The pin 3T also has a notch 3T which coincident with the periphery7 oit the hole in which the plunger 29 is slidable. The hole 37, however, is normally held out oit coincidence with the periphery ot the hole in which the pin 29 is located, by means oli a spring Thus it will be vseen that the reverse button cannot be depressed until the releasing pin 37 is pushed in until the opening 37 therein comes into regis ration with the plunger 29a. The pin 37 is prevented trom turning by the pin 39 which is guided in the slot 40.

A Afiat arcuate strip 4l lies upon the arcuate ledge il forming part ot the lower housing` section il, as shown in Figure 3 and is held thereon by means oli a series ol guides 42. The strip 4l. is broadened as shown in Figure 2 into a plate 4l to which is secured a yoke 43 as shown in Figure 8 in which is slidably mounted the eccentric 44 which is secured to the revolving tumbler 45 ot a wel l known type oi lock which is mounted in the housing. The arcuate strip 4l has secured thereto a series oil? blocks 46 which lie. at one side ot the path ot the levers 20j 2l, etc.. as shown in Figures 2 and G when the strip ell. is moved to the unlocked position. Thiy 's done by means oli the key 47 which. turns the tumbler 45.

With the engine running` the brake remains applied only so long as the lever is depressed. ln order. theretore, to lock the lever 25 so that it cannot be moved either to set or release the brake, a pin 25 as shown in .Figure is secured to the outer end therro't and a block i611 is secured Ato 'the plate Ll l,

so that as the plate 4lu is moved by means of the key 47 it will withdraw the block 4C and permit movement ot the lever 25, se `ting and releasing the brake. As the plate 4l, however, is moved back to its locking position as shown Vin dotted lines, the block 4G is moved into the path ot the pin Q5 so that it cannot be depressed 'trom the Al'ull line position shown in liigure 7. It the plate 4ln is moved while the lever 25 is in the depressed position as shown in. dotted lines, the plate 41a will pass over the pin Q5 thereby preventing the brake from being released.

The arcuate strip 4l is also provided with hooks 41h which are adapted to engage he lugs 10b secured to the upper housing section l() as shown in Figure (i, thereby securely locking the upper and lower housing sections together when the key 47 is removed.

While I have shown and described but a single embodiment oit my invention, it is to be understood that it is capable ot many modiiica'tions. Changes7 therefore, in the construction and arrangement may be made without departing from the spirit and scope ot the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view ot the prior art.

What I claim as new and desire to secure by Letters Patent is:

l. A. button block comprising a series olE buttons, a series ot levers, each movable by a button7 an element movable by each lever. means tor preventing more than one ol." said levers being moved from its normal position at a time, and means uncovered by said last mentioned means ilor indicating which button was last depressed.

A. button bloclr comprising a series oi" buttons7 each ot' which is operatively connected to a member to be moved. a housingfor said members consistingl el? top and bottom sections and a lock for locking` said sei-- tions together and tor locking all ol'A said members against movement.

A button block comprising a .series ol buttons, a series ot levers, each movable by a button. an element movable by each lever. a series oit spaced members 'tor preventing more than one oli said levers being` moved Ytrom its normal position at a time. and means opposite each button and visible in the dark and norn'lally covered by said spaced members, said means being` uncovered by the last operated button tor indicating which button was last depri-issed.
