T0 ZZ whom t may concern.'

Be it known that I, ALBERT J. Huss, a citizen of the United Stat-es, residing at Springlield, in the county of Clark and State of Ohio, have invented certain newand usef ful Improvements in Motoiineter Locks, of which the following is a. specihcation.

rIhis invention has for its object the pro vision of means whereby a iiiotorineter will be secured in a radiator cap so that it will be guarded against loss :and against siii'i'eptitious removal. 'lheinvention seeks to provide a simple but efficient mechanism where'- by the operation of the motoiiineter and the placing and displacing of the radiator cap will be premitted but separationv of thezmotorin'eter trom the cap will be prevented eX cept through manipulation' by an authorized person. These objects, and other objects whicliwill incidentallyappear in the course of the following description, are attained in suc-h a device as is illust'ated in the accompanying drawiiig,and the invention resides in certain novelfeatures which will be particularly pointed out in the appended claims.

In the drawing: y

Figure 1 is a sectional elevation showing my invention applied toa n'iotorn'neter;V 4

Fig. 2 is a vertical section on the line 2,--2 ofFig. 1;

Fig. 3 is a horizontal section on the line 3 3 of Fig. 1, :and

Fig. e is a horizontal section on the line LA of Fig. 2. y

The motormeter 1 is of the usual construction having a stem or hollowbody 2 inserted through the cap 3 of the radiator 4. In applying my invention to the motorineter, the nut 5, whereby the motorn'ieter is securedpin the radiator cap, is first removed and atyoke 6 is then vfitted over the stein or body 2, the nut 5 being then retitted soas toclainp Vthe yoke against. the under sido of the radiator up. '.lhe yoke 6 is somewhat longer than the stein or body ot the iiiotoinieter so that it will depend below the saine when in place, as shown in Fig. 1, and upoii the lower end ot the yoke is hung a sleeve 7 having an eye S at its upper end to engage upon the yoke, and providedwitli a longitudinal slot 9 in its lower portion, the lower eiidof the sleeve being open for a purpose which will presently appear/ The slee-ve is also providedexternally between its ends with an annular recess ..10 adapted to. receive the tumbler rings 12 which encircle .tl'ie sleeve and have anv external diameter equal to the maximum external diameter of the sleeve whereby the outer surfaces of the tumblers and the sleeves will lie flush when the parts are assembled, as clearly shown in Figs. 1 and 2. Through the inner circumference of each tumbler ring is formed a longitudinally extending notch 13 which, when the tui'nblers are properly set, registers with the slot 9 in the sleeve. locking rod 114 has its upper smooth end iitted within the borexof the slee-ve 7, an'd upjon the upper smooth end ofthis lrod are lugs 15 which are adapted to lit withinthe grooves or spaces defined by the opposed inclined or beveled faces 1l of adjacent tunibler rings, as shown in Fig. 2. These lugs 15 arevtapered outwardly to conform to the ltapero'f the acesll of the rings and they are also disposeed in alinement longitudinally or' the locking rod whereby they may lpass through the slot 9 in the sleeve when the` parts are being assembled, and when the partsare asembled the spaces between adja cent lugs will each receive the inner edge or peripheral apex of one of the rings, as clearly shown in Fig. 2i. It will be understood,

of course, that the lugs may be connect-ed so as to form a continuo-us rib having notches in its outeredge. l y y Upon referring to Fig. `2, it will be noted that the vertical cross sectional outline oi a tumbler ring is a truncated triangle presenting a fla-t inner extremity to bear against the intermediate reduced portion of the sleeve or vertical wallof the recess 10,. faces diverging outwardly froinsaid extermity to engage opposite edges of the respective tapered lugs, and basal side faces extending radially outward from the `diverging'g face-s to bear against corresponding portions of adjacent rings or the ends of the recess in the sleeve. 'By this construction, the outer ciroumferences ofthe rings and the sleeve will be maintained iii hush relation.

The lower portion of the locking rod ist threaded, as shown at 16, and is adapted to pass through the upper end of the anchor 17 and the expander 18. The anchor 17 consists ot plurality of arms 1f) having tlieirends oi'itturiied, :is shown at 20, and

vcoi'iiiected at their upper ends by a central neck 21 thro-ugh which the locking rod passes and which isconstructed with notches 22 to receive lugs 23 formed on the' lower end oit they sleeve dTwhereby relative turning of the `s'leei'fe or' the anchor will'be prevented. The

expander 18 consists of a substantially conical body over which the arms 19 extend and having a projection 24 upon its outer surface to pass between any twoo-f the arms and by its engagement with one of the arms prevent rotation of the expander relative to the arms. rlhe threaded )ortion ofthe locking rod 14 passes througn and engages the threaded bore of the apex 25 of the pander, as clearly shown in Fig. 2.

Upon the outer surfacel of the 'several tumbler rings 12 are displayed in any convenient manner numbers, letters or other characters, indicated at 26, Iand graduations 27 are also formed or displayed iipon the rings adjacent the respective characters and in alinement therewith..` Similar characters 28 are formed upon the sleeve 7 immediately adjacent the lowest ring 12, as shown in Fig. 1. The notch 13 in 'each tumbler ring 12is disposed in radial alinement with one of the characters 26 upon the external'surlace of the ring so that it has a fixed position in the ring and the combination of' the lock may be varied by changii'ig the rings, as will be readily understood. In the manufacture ot the device, the sleeve is litted -with tumbler rings lset to a certain combination yof the letters, numerals or other characters dis,- played upon the outerfsurfaees of therinfis. The anchor and the expander are iitted upon the locking; rod with the arinso'ix the anchor close together so that they may be inserted -throught-he 4filling nipple of the radiator and clear the same. The head 29, which 'is formed on the locking rod immediately at the upper extremity of the threaded portion thereof, isthen turned so that rotation will be imparted to the rod and by its threaded engagement with the expander. 4will cause the expander to ride upwardly inasmuch as rotation of the expander will be prevented by the engagement of the projection 24 against one of the arms. .Y As a result of the movement of the expander upwardly upon the locking rod, the arms 19 of the anchor will be bent outwardly so that their 'extremities will project beyond the walls of the filling nipple ot the radiator and, consequently, any. attempt to withdraw the vdevice from the radiator will then be resisted by the engagement oi"- the extremity 20 against the innersnii'ace of the radiator. top. The tumbler rings are then set to the combination of tbe lock in which position the notches 13 inv all the rings will be in longitudinal alinement and adapted to register with the lugs 15 upon the rod 14. The sleeve, with vthe tumbler rings thereon, is then placed over the upper end of the locking rod and pushed home so ythat the end ofthe sleeve and the end ofY the neck21 will abut. The

rings are then shifted sothat the notches therein will be carried out of alineinent with the @spes/five lugs" 1 5 and il??r 111e? Will la@ engaged between opposedtapered surfaces of adjacent rings, the device being thus set so that the mot-ormeter cannot be separated from the radiator cap. Vhile I have shown. and described the lock as being secured in place by the nut on the motormeter body clamping the suspending yoke to the radi ato-r cap, it will be understood that the yoke ma be otherwise secured to the motormeter bo y, as by riveting or like means. From the foregoing description, taken 1n connecL tion with the accompanying drawing,a 1t will be seen that I have providedavery sim; ple device which will prevent theft. of the motormeter lwithout interfering with the temporary removal of the radiator cap when lilling or' the radiator is necessary and also permitting the removal of the motormetei for thepurp'ose of repairs lfthe person making the repairs kno-ws the combination controlling theseveral tumbler rings. g Having thus described the invention, I ciaim l.
