J. R. HAINES 1,996,417 AUTOMATIC SHUT-OFF FOR SWITCHES Filed May 1, 1935 ATTORNEY Patented Apr. 2, 1935 mreo s PATENT OFFIGE 1,996,417 AUTOMATIC sun-r oFi FOE swlronzs Joan Ralph names, mama, is. .1. Application my 1, 1933, semi No.'668,831 's'oiai'ais. (01. zone) This invention relates to an improved steering wheel actuated shut off for switches for use in connection with direction signals as installed on motor vehicles, and particularly in connection with the type of "switch set forth "and claimed in the application of John Ralph Haines, filed March 25, 1932, Serial No. 601,279. 7
In switches of the type disclosed in the above identified application manual means are employed'for actuating the switch; either on or off. However in the present invention, wanes is the purpose to operate the switch manually, it is also the purpose to restore it t'oin'itial' position auto matically through the medium of a steering wheel of the motor vehicle.
Another purpose is to provide a lev'er with means 'to clamp the lever on a rotating rod or shaft of the switch, said rod or shaft carrying the type of frog as disclosed in the co peiidihg application above identified.
Another purpose is to'pr'ovide means mounted on the lever and cooperating with a segment guide on the top of the housing for the switch, said means adapted to engage with a notch in the segment for retaining the operating lever in its initial position, the ends of the segment guide acting to limit the lever in its two extreme positions, said positions being for holding movable contact arms of a switch frog in engagement with certain contact points of the switch.
It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.
The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawing and claimed.
In the drawing:-
Figure 1 is a view in elevation of a steering column with a steering wheel in section showing an automatic shut off as applied to a switch supported on the column.
Figure 2 is a plan view of the steering wheel with the automatic shut ofi applied to a switch.
Figure 3 is a sectional view on line 3-3 of Figure 2.
Figure 4 is a plan view of the switch showing the automatic shut off.
Figure 5 is a plan view with the cover of the switch casing removed.
Figure 6 is a detail view in elevation of a part of the switch casing showing a side view of the off with thejsihiit off lever in a position readyjto be restored to initial position.
p gure 7 is a sectional view through one of the actuators 20 as applied to'the spoke of the steers hs Figure 8 is a sectional view on line 6 0! Referring to the drawing l identifies a casing for housing a switc h s uch as disclosed mine above iiti li ion s d s ch nc udiing a switch frog 2 for cooperation; with certain contacts for closing circuits to prove whether or not certain direction signals or lamps are lighted. The s vvit'chfalso includesa rod or shaft 3"extend} ing through the to p'of the housingprovided with a square; or rectangular end 4; which" enters correspondingly shaped opening} of a switch lever 6; this correspondingly shaped opening is io rimedythe side'of the level is; split s Wn. at .fifi th e. jsa sc w. 1 af' ls if eme; n o w vewh amzwan is spac ed or split from the belly of the later. This screw tightens the wall toward the body of the lever, in order to clamp the lever on to the square or rectangular end of the shaft or rod.
The body of the lever is provided with a rectangular opening 8, in which a lug 9 of a detent I0 is pivoted upon a pin H. The lever engages under an arch l2 of a curved segment l3, which is a part of the top of the housing. This curved segment has a notch M, which receives a V- shaped lug l5 carried by one end of the detent. The other end of the detent has a lug IS with which one end of a coil spring l1 engages. The other end of the coil spring sets in a cavity IQ of the body of the lever, thereby so tensioning the detent as to retain the V-shaped lug on one end of the detent in engagement with said notch H. In this manner the lever is retained in its initial position, with the switch frog in its initial position.
The steering wheel I9 has two of its spokes provided with actuators 20. Each actuator consists of a block 2| including a band 22, which is secured upon the spoke as shown. This block 2| has a socket 23, in which a ball or spherical member 24 is mounted. The ball or spherical member is spring tensioned as shown at 25 and is adapted to ride over the V-shaped lug 26 on the upper face of the detent opposite the V-shaped lug l5, when moving the steering wheel in one direc tion, that is to say, when the switch lever has been actuated to its limiting position, for either having operated the switch when being moved to prove certain signals, or when having been moved to prove certain other signals. The spring tensioned ball or spherical member upon return of the steering wheel to its initial position for driving straight ahead, after having actuated the switch, the spring tensioned ball or spherical member engages with the V-shaped lug on the upper face of the detent, for restoring the lever to its initial position.
The invention having been set forth, what is claimed is:
1. A direction indicator switch comprising a steering-column-carried casing, a switch lever having a pivotal mounting on top of the casing for swinging movement forwardly or rearwardly to close either of two direction indicating cir-.
cuits, the casing on the top being provided with an arcuate segment straddling the lever to limit both the forward and rearward movements or so that the latter may impart movement to the lever except when the lug is engaged in the notch of said segment.
2. A direction indicator switch comprising a steering-column-carried casing, a switch lever having a pivotal mounting on top of the casing for swinging movement forwardly or rearwardly to close either of two direction indicating circuits, the casing on top being provided with an arcuate segment straddling the lever, a detent having a pivotal mounting intermediate its ends,
the detent being carried by said lever with one end overhanging the segment, a spring interposed between the other end of the detent and said lever to yieldingly impel the overhanging end of the detent toward the segment, the segment having a centrally disposed notch and the detent having a lug engageable in said notch to yieldably retain the lever in neutral position, and a steering-wheel-carried actuator for movement over the casing in rotation of the steering wheel,
the detent being disposed in the path of said.
actuator so that it may impart movement to the lever except when the lug is engaged in the notch of said segment.
3. A direction indicator switch comprising a steering-column-carried casing, a switch lever having a.'pivotal mounting on top of the casing for swinging movement forwardly or rearwardly to close either of two direction indicating circuits, the casing onthe top being provided with an arcuate segment straddling the lever to limit both the forward and rearward movements of the latter, a detent mounted on the lever and extended beyond the mounting to ride on the segment, a spring connected with the detent and carried by the lever to yieldingly impel the extended end of .the detent toward the segment, the segment having a centrally disposed notch and the detent having an element engageable in said notch to yieldably retain the lever in neutral position, and a steering wheel-carried actuator for movement over the casing during rotation of the steering wheel, the detent being disposed in lever is at either end or the segment when the v actuator is betweenthe ends of the segment but moving toward that end at which the lever is disposed.
