SUPPORT FOR SPEEDOMETER-GEARING. i t

To all wiz-om it may concern:

Be it known'that I, Anni-:ur L', Soren, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Chio, have invented a certain new and useful Improvement in Supports ior speedometer-Gearing, ing is a full, clear, and exact deserii'ition.

This invention relates to improvements in devices for supporting' the driven gear members for speedometers or other measuring'instruments in proper relation to the.

gear on the front Wheel of a inotorgvehiclc. It is customary at the present time and, in fact, almost 'the universal practice 'to support the driven gear which meshes with the gear on the front wheel and also the other gears which transmit the movement of the driven gear to the flexible-shaft leading to the speedometer by meansoi' a rather complicated clamping device which isfastened about an arm extending outwardly fromithe steering'knuckle. `This clan'iping,r device is objectionable not only because of its complicated construction and nuniber of parts of which it is composed, but also for the reason that it is liable to slip along the arm on-which it is mounted.

The main object of the present invention is to do away with this clampingdevice and to provide for the elements above mentioned, a supporting means which(requires a less number of parts, which is simple i-n Construction, easily applied to or removed from a steering knuckle, which permits the use of certain standard parts of the coni' struction commonly employed, and which holds the supported elements in proper' pothe present time and does away with the liability of disarrangeinent ot' the coperating gears, such as occurs bythe slipping of the clamping' device at present employed.

The above and other objects are attained by my inventionwhich may be briefly summarized as consisting in certain novel details of construction andA combinations and v`arrangements of parts which will bc described in the specification and set forth in the appended claims.

positively and securely than atl Specification of Itetters Patent. Application led May 5, 1910. Serial NO. 559557' of which the t'ollow- -ing taken substantially `which supports former being adapted to be Pa touted Octn, 1911.

Reference is `had to, theaccompanying sheet of' drawings, wherein* Figure l is a sectional view through the frontaxle looking' in the direction of the front wftieel having the gear which iileshes with the driven gear torming part of the transmitting' mechanism between the front. wheel and the speedmoter, or other speed of," distance measuring' device, this section bealonglhe line l-l of Fig'. 2, lookine in thefdircaftion indicated by the arrow; -l ig. 2 is a plan view ot the same showing the hub of the front wheel referred to; Fig. 3 is an enlarged vertical sectional view through the steering' knuckle 65 and a portion ot.' the speedometer gears-upporting mechanism.

teierring' novv to the tig'ures'ol thel drawing, l0 represents a `portion ol the't'ront axle having' at 11,'(Fig. 1)-, a yoke portion 70 in the usual 'manner a steering' knuckle l2 shown by dotted linges in Fig. 1 and shown partially by full l in liig'. Il.' This steering knuckle supports in the usual manner the front wheel of a motor vehicle, the hub ot" this wheel being shown in Fig". i2 at lf3. 'l`heknuckle 12 is provided` as is usual, with two arms 14 and l5, the connected to the steeringY column, `andy the latter being com nected by a'i'od 1G to a correspondini;` arm on the steering' li'nuckle supporting the opposite t'ront wheel so that the steering mov`ement' inmarted to one knuckle and one front wheel will be transmitted to the other front wheel. These two arms 14 and-"15 are formed in one integral piece havinga shank 'portion 17, which is beveled, as shown, and is usually secured in a suitable:beveled opening in the vertical;'portion ,ofy the 90 knuckle l'by means of an ordinary nut 22 and are employed for transmitting movement of the gears 19 and 20 to a flexible shaft contained within a lflexible tube 23 and extendingto. the speedometer oriother measf uring instrumentl on the dashboard of the vehicle. These parts just described may be .of any -usual or suitable construction. The

Acasing 22 land ,the gears contained' therein,

-ng jaws whic U- as well as the spindle 2land gear 20 are 28 which is fixed to the steering knuckle and onto the end of which the clamping niember 27 is .rigidly secured. In the embodi.

ment of my invention here shown, the member 28 isa s ecial nut which is screwed onto the threade end 18 of the member having the arms 14:` and15,and replaces the ordinary nut which when screwed onto the threaded portion 18 of said member secures the latter g to the knuckle. This. nut is provided ,with an extension having inl its .outer end l'a threaded socket 29, and the clamping member 27, as well as the other parts carried thereby are supported and secured in proper position by means of 'a boltl or. screw 30 which passes'through the jaws of the clam ing member 27 and is screwed into the soc (et 29, it being understood that this nut 28 Iis of suicient length that when the clamping device .27 isfasteiied onto the end thereof, the gear 20 will be in proper relation with respect to the gear 19. However, an adjustment of the gear 20 is permissible because of the arm 2G and the member 24 f which is'clamped thereto. It will be noted that when this bolt 30 which clamps the member 27 'to the end of the nut 28 is tightened, it not only rigidly fastens vand supports the speedometer gears to the clamping nut 28, but also clamps the member 27 securely to the arm 26. y

This construction' which I haveprovided has been found by long usage to be veryeffective and possesses all the different ad-` vantages above enumerated. At .the same time it is inexpensive and can be applied with slight modifications to practically ,all machines. Having thus described myinvention, what I claim and desire to Secure 'by Letterslat- 1; In combination with avehicle wheel and steering knuckle having a vertical portion supporting the wheel and apair of steering arms, a gear carried by the wheel,
