REVERSTNG MECHANISIYI HAVING STATIONARY SLEEVE.

Application iiled April 13, 1921. Serial No. 461,144.

To all 'whom t may concern.' y

Be 1t known that T, DAvinC. liLAU sMEYnR, a citizen ofthe United States, and residing,` at

36355 Burch Ave., 'itlyde'Park, Cincinnati,

. means therefor'.

Such motion-reversers, present many mechanical problems on account of the necessity of simultaneously attaining strength,

precision, durability, reliability, smoothness,y

nate directions thereto, with the effect that.

the rate between it and each Aof the gearsin turn is twice the absolute rate of the gear itself. As a result, eachgear in reality runsl twice as fast on its bearing` as it would if said bearing was iixed.

It hasjfor long` been recognized thatthis condition was provoca-tive of undue wear but no cure, compatible with other structural necessities, has heretofore been developed.

By virtue of the structure herein proposed,

this defect has been eliminated without,

however, necessitating the sacrifice of certain other very desirable structural characteristics.

The high relative motions previously noted, together with the degree of looseness occasioned thereby and incidental thereto, likewise obtained between the movable parts of the clutch and, considering the nature of the bearings resorted to, had the effect of 'prohibiting` the use of certain very desirable types of clutchg'notably, so-called fedisk clutches, and also cone clutches. This prohibition followed from a tendency to accentuate the eccentricity which much needs @ne prominent defect of exist `to some extent initially, and to a great extent in time, due to the impossibility of yattaining' absolute precision in any mechanism. This invention proposes a construction admitting of the use of laterally-operating clutches which, for purposes of definition, are herein termed disk clutches; this term being employed to contemplate the various species of clutches characterized by having two or more flat or conical friction surfaces, such for example, as either multiple orsingle disk clutches, or cone clutches.

`Furthermore, in motion-reversers of this description, a plurality of parts are of necessity arranged in co-aXial relation and the smoothness of action, durability, and general efficiency depends very largely upon the initial` precision and maintenance of the coaxial relation. An objective of this invention is to provide a structure whereby this co-axial relation, from the manufacturing standpoint, may accurately be obtained initially and maintained subsequently without entaihng undue cost, or undue manufacturing diiliculties. ,Moreoven it is not only nec-- essary that the gears` shall initially be arranged to intermesh accurately with respect to' their pitch-lines, but also provision must be made, whereby they may be adjusted in this respect to compensate their wear.` This adjustment must also be compatible with the presentation of a correct operative relation with the clutches associated with the gears. This desideratum is likewise provided for in an effective manner by the structural arrangement herein proposed it bein achieved without intei,"feiing with the attainment of compactness.

Other objects and advantages will be in part indicated in the following description and in part rendered apparent therefrom in connection with the annexed drawings.

To enable others skilled in the art to so fully apprehend the underlying features hereof that they may embodythe same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed as a part of this disclosure, and in such drawings like characters of reference denote corresponding parts throughout all the views, of which kFig. l is a longitudinal section showing the general assembly of the element of this device. Fig. 2 is a transverse section taken tudinal section showing a still. further modification in which the clutches are mounted directly on the shaft.

'the trame is therecteristically provided with n'ieans Afor providingv stationary journals for the mounting` oit tivo con.ersely-rotat bevel-gears. A convenient Way ot achievu g that end is illustrated in ll es. l and wherein indicates a bracket internally projecting' troni a side-wall et the casing; it hein; l'lrrily allixed thereto by a screw 2l. This bracket provides an elongated bearing-element 3 in the nature olt :L stationary sleeve; the ends l and 5 of which constitute stationary journels or lecturingl inerehers on which the fears are rotatably inountcd.

Theshape et the ln'acket is7 ot course. immaterial so long.; as it adniits oit being` ar janged in the intermediate position shown and it isj ot' coursey .immaterial vl-ether the journals l or 5 are into@ "il With sai-.fl bracket 2 or are otherwise ritw lly atteched to it.

These gears are rotatably.l aswell es trenslatebly. mounted on the journals Llend 5 (as 'for eil eniple 'through the agency of the brass bushiup; ll.) so as freely to admit oli movement against the said thrust bearing. ln the course of time, suiiicient weer Will-take pla e to impair the original precision ot the intermesh and, therefore. provision niedefor adjustingy the gears toward the 2 2.

lnasinuch as both the gears 9 end l!) are journaled on a single stationary clement, they admit ot bei f held very .3 y in an accurate coa2;ia.i relation; there being' no intervening loose element to iinpeir the preV4 cision ot the niount. ln pre vious motion rcversers, the opposed bevel gears were habitually inountedon u rota uieulier; this member being in turn suitably coiuiectcd to seine other eleinfnitV et the trai 1 ssion trein. 'l'hrough the agency of approiiriate clutel esj either gear could be connected with said rotary member so Vthat the two would rotate together as a unit' leaving` the other rear lree to rotate independently ot the member on which it 'was mounted but in a direction opposite thereto. The relative nioiiou between the tivo yves accordi n t. i;, i as tast as il the nienber hed had no rotation itself. This c idition tended towards preunu'nrc ivear and occasioned v ier re` placements and troubles; not vithstendiiug The instant extreme care in lubrication. construction avoids this dilliculty in a man ner entirely compatible With conipactness and other dcsideretuins.

The `gear 9 is of sinall diameter and its bore is comparatively small so that. while infrinittinf the `gear 8 to be set close to the central. axis ot the spindle, it will nevertheless rnn smoothly. lillhile such rear 9 niay have its outer portion congurated in any manner appropriate to the type oi clutch used, it will be noted that the example illustrated presents a very desirable characteristic; to Wit, it merely hes a sii ple disle like flange le o;c small diameter termed on its end; thereby avoidingthe complicated cup-like lorinetions heretofore demanded to meet the necessities of clutches of the e3;- pending' ring type previously required 'for various structural reasons in mechanisms ol" this general nature. lt is, ot course, much cheaper to manufacture lgears of the simple forni shown in the herein lillustrated preferred embodiment this invention.y since the disk-tienne lil may not only he rende inteerel with the itsel't but may be il'orin ld from the ori` -nal blank Without requiring the removal of any Agreat amounts ot stock which, of course. of hielrgradt expensive steel.
