. of'New Rochelle, in the count of Wcstchester and State'of New Yor have invented pertain new and useful Improvements in Trip-Resets for Flush Mountings, ofwhich the following is a specification.

' My invention relates to a'flush mounting for odometers and similar instruments which include mechanism requiring a, manual resetting of certain of-the mechanical parts and constitutes a continuation of the subject-matter of mylcoending. application, Serial-No. 33,255,'file June 10, 1915.

One of the -objects of my invention isto provide a simple construction for positionmg an odometer in a mounting arranged so that the instrument or at least 'the mechanism thereof isin rear of the mounting but the manual control'for resettin the same is conveniently accessible from t e front of with a hollow cylindrical bearing 14' exthe mounting.

A further object of the invention is to provide a-construction which can be easily and quickl actuated and which will be free of loose p ay ofany of the parts.

Various other ob ects and advantages of the invention. willbe in part obvious from' an inspection of'the accompan ing drawings and in part willbe' more fu ly set forth in the following particular de'scriptionof one fornr of ,mechanism embodying my-invention, and the invention also consistsin certain'new and novel features of construction and combination of parts hereinafter set forth and'claimed.

In the drawings:

Figure 1 is a plan view looking down upon an odometer positioned on a mounting and disclosing a preferred embodiment my invention;

Fig. 2 is a detailed enlarged view partiall in ig.1;and

Fig. 3 is a fr ientary front view of the device shownin ig.2

In the following description and in the claims, arts will be identified by specific application to similar parts as the art will permit.

In the drawings there is shown a mount- 66 ing 4 which may be in the form of a plate Specification of Letters Patent.

in section ofiparts of the device shown Patented Dec. 2, 1919.

' Application filed .1 and 16, 1%115. Serial No. 34,344.

constituting part of the complete instrument The mounting has an opening 5 in which is fixedly positioned the odometer 6 with the front facing 7 thereof substantially flush with the front 8 of the mounting and with themechanism containing casing 9 thereof projecting rearwardly of the rear face 10 of the mounting.

The revolution counter mechanism of the odometer includes a pair of gear wheels 11 and 12 with a third gear wheel 13 normally constituting a gear connection for driving one of the gear wheels 11 from the other gear wheel 12, by locking the two together.

In orderto reset the counter mechanism it is necessary to rotate the gear wheel 11 independently of the gear wheel 12 and this is accomplished by shifting the third gear wheel 13 and rotating the same manually.

For this purpose, the casing is provided 11 and 12 by means of a spring 16 housed within the bearing. The outer portion 1'Z of the shaft is enlarged to provide a shoulder 18 within the bearing to engage one end of the spring 16 and to provide a relatively long sliding fit between the shaft and its bearing.

A manually actuated wheel 19'is loosely mounted on theenlarged portion of the shaft and is maintained in position fixed against movement longitudinally of its axis -of rotation and in engagement with the outer end of the bearing-by means of the. s ring 20. This spring is housed within t e hub 21 of the wheel and bears thereagainst and ;-against a shoulder 22 formed on the shaft adjacent its outer end. The

' wheel is of relatively large diameter so that a portion thereof may project through an opening 21-} in the mounting. The periphery of the wheel is provided with a knurled surface 24 to facilitate the rotation of the wheel when engaged by a finger 'of the operator moving across the projecting portion of the wheel.

The outer face of the hub '21 is provided with a pain of diametrically extendim slots 35 constituting one element of a clutfin'the coactiug element of which is a pin '26 set in the outer end of the shaft amt projecting.

, laterally from opposite sides thereof. The

clutch is normally maintaii'ied in inoperative position by means of the springs 16 and 2t). In order to shift theshal't longitudinall v againstthe action of these springs, the outer end thereof is engaged by a manuall a tuated control memher 1T preferahlyfin the form of a hell crank lever. One arm 2B of this lever provides a hearing surface for engaging the end of the shaft which' across the hend hy an angle memher 3.? extonding across the rear side of the, bar 32} and fastened to tho levcriry means of a rivet :30.

In operation, it will he understood that the parts are normally in the positionshown in Fig. :2. in which gear \vheel.l mav he considered as the driving memher of the odometer mechanism and. geared to the driven memhor It by means of the shil'tahle. gear whccl til. Should it he desired to reset the. mechanism by the manual rotation of the goar \vhcol ll. the gear wheel 13 is shifted longitudinally of its axis of rotation until it is in engagement sololv with the gear whoel ll, in which position the gearwheel- 13 may he rotated hv the manual actuation of the wheel 15). In order to bring the wheel 15) into operative connection with the gear wheel 13. the operator presses upon the thnmliiiece. 30 thus swinging the, lever about its fulcrum into heariug engagement against the outer end of the shaft 15 to move the pin element of the clutch into engagement with the slot element; 2; and

against the tension of the s rings 16 and '30.

the springs 16 and 20 to react on the szhaft 15 thereby to reset the gear wheel 13 into v its locking engagement with the gear wheels 11 and 12 and simultaneously act to move' the clutch'into an inoperative position. v

By means of a device of tlns character it is possible to mount the odometer flush with theouter face of any suitahle mounting such as the dash-hoard and at the same time provide a positive control for theresetting mechanism positioned in rear of the mounting. j

\crv little of the mechanism need pro- 'ject through the mounting and in this way the mlometer-mav he mounted in position without dost roving the neat appearance provided hv' tlush mounting of such instruments. There are no rotating parts projects ing through the mounting and the'mannally actuated wheel is normally disconnected from the mechanically actuated parts of the mechanism when in its nornuil position, The shaft is mounted upon relatively long hearings so that any loose play hetween the parts is reduced to a minimum and itis 0bvious that the spring pockets may he utilized This shitting ot' the shaft, ln'eaks the locked gear (ollllectiolj hetweon the. gear wheels 11 and 12 and moves the gearwheel 12% into mesh with the gear wheel 11, so that. the' l'otationof the manually actuated wheel 1!) will cause. the gear wheel-l3 to rotate the gear wheel 11 in either direction desired and thus ohtaiu either a forward or a reverse setting of the counter indicative elements of the odometer.

lieleasing tension upop the levers-permits as oil pockets.

The mounting may he sold withthe mechanism and .casmgas a part thereof, thus .providipg a neat and simple type of instrument particularly designed for Tlush mounting.

\Vhile I have shown aml doscrihedfnnd ha ve pointed'out in the annexed claims, certain novel -fea'ttn'es .of my invention, it will he understood that various omissions; substitutions and changes in theform and details of the device illustrated and in its operation may be made h thoseslgilled in the artwithout departing trom the spirit of the invention.
