Another object is to provide avariator wherein the selecting gears are arranged in tie-rs, making it possible to place the shafting substantially in a circle common to all tiers, thereby providing ready' setting means.

Another object is to provide variating means whichwill compute only at the 'figures' at which it is set.

Another object is to provide variator'mechai-"- nism having the operating shafts =arrang'edsubstantially circularly about a centrally disposed difierenti'al' or output means permitting the" use of selecting means operating'circularly, this being made possible by carrying: the shafts through: the 1 2 such a way as to properly compound certain of the gearing.

Another object is to provide a variator which is compact and strong, and is so" constructed and the use of simple tools and fixturesnecessary' for. assembly.

Another object of the invention is to provide a form of variating mechanism in'which the groups 0 of gears are all of substantially the same size" and so disposed that the center lines of the shafts thereof are on the same periphery so as to provide" varied.

'Another object of the invention is to provide groups of gears of substantially the same size-- mounted on drive shafts, the axes of which are on a common periphery, connecting means forthe selecting gears being through differential or lecting gears being movable by rotative setting or setting means for predetermined price ranges to engage the selected of said selecting-gears for said ranges, and the zero setting of any of saidpredetermined price ranges being accomplished ,by the same rotative setting.

Another object is to provide avariator wherein selector rings are providedfor setting the device, the rings being so constructed and arranged that a ring can only make one selection ata time; yet selection may be easily accomplished ash isdone-a only by a rotative movement, the movement and;

relation of the parts being such that; gears do not have to be felt for, as where the faces ofgears must be meshed.

0: Another object of the invention is to provide variating mechanism wherein the setting means is so arranged that it must be positively-and-en tirely set or it will be inoperative, and in the set-' ting one of the setting means must be moved to a predetermined position from its locked position prior to setting the other setting means.

When in such alignmenta setting of the, tens portion of the variator is indicated. In the embodiment shown the-tens shows that it is setfor ten cents. An-l other index marked 218 is provided in the knob 264,, which index must. be. moved into alignment with.:theg1pointer 216 in order to set the knobs 280 and 282 of the cents and tenths of cents portion'of the variator.

Theknob- 264 is provided. with the push button 1 284 engageable with a slidable rod 286 (Figures 4 and 8), therod extending inwardly through the pawl carrier :288-andengaging one end ofthe paWl290. The pawl 230 is pivoted as at 292 to the pawl [carrier and the opposite end 294 of the pawl -is urged into engagement with the fixed ratchet 296 by means of the spring 298., The fixed ratchet has spaced notches 291 correspondingto-:thepositionsof engagement of the gear I52 and the selected gears I24, I26, etc; The pawl carrier 288 is provided with the 66-tooth gear 300 meshing with the 32-tooth idler gear 302 (Figure 8). which in turn meshes with the gear I58. Thus rotating the shaft 260 causes rotation of the gear I58 through gears 300 and 302, it beingseen that itisfirst necessary to depress the button 284 to cause releaseof the pawl 294 from the engaged tooth of the ratchet 296.

The shaft 260. can be-rotated in only one directionv andafor thispurpose the pawl 304 (Figure 8) is provided pivotally connected to the shaft 306, a spring 368 being provided for urging the pawl toward engagement with the gear 306.

Shaft 366 is provided with the '10- tooth gear 3M (Figures 2 and 9) meshing with the 32,-tooth idler 3I6 which in turn meshes with gear 208, gear 3I6 being rotatably mounted on the fixed shaft 3I8, said shaft, being carried by the support 262. Thus rotation of shafts 366 rotates gear 288 to move the gear 2 I4 bodily to positions to engage selected gears I32, I34, etc.

Knob 282 is provided with the shaft 320, said shaft being provided with the YO-tooth gear 322 (Figure 11) meshing with the 32-tooth idler gear 324 pivoted to the shaft 3 I 8 and meshing with the gear 2m. Thus rotation of the shaft 320 causes rotation of the gear 2H} and, consequently selectively moves the gear 222 to engage the selected gears I32, I34, etc. indices 325 from zero to nine, corresponding to thetenthsindications, said indices being adapted wto be aligned with pointer 321 on the housing 22 for readily reading the tenths setting.

Knob 282 is provided with the I is in alignment with the index 216. The pawl 328 is pivoted to the shaft 336 and is provided with the inner arm 330 (Figures 9 and having the spaced pawls 332 and 334 adapted to engage in ratchets 336 and 338 respectively provided on idlers 3i 6 and 324. The ratchet teeth on ratchets 336 and 333 are so spaced as to represent the movement between the adjacent selected gear drive shafts 30, 50, etc., so that when the pawls 33d and 332 are in engagement, that is, in the position shown in Fi ure 9, engagement between the idler 2 I4 and the selective gears I32, I34, etc., and engagement between idler 222 and the selective gears I32, I36, etc., is insured.

The spring 343 is secured at one end to the support 342 and at the other end to the arm 344 provided on pawls 328, 333 and 332. The pawls 332 and 33 3 are thus urged into engagement with the ratchets 338 and 336 as shown in Figure 9 and in that position, unless the notch 326 is moved into alignment with the pawl 328, the shafts 306 and 32% cannot be rotated as a positive lock is provided between pawls 328 and th carrier 288. When the variating mechanism is being set, that is, when the notch 326 has been moved into alignment with the pawl 323, unless the gears 2I4 and 222 are in engagement with one of the gears I32, I36, etc., it is impossible to set the knob 264 as the pawl 328 cannot be moved out of the notch 323, due to the fact that unless the gears 2I4 and are in engagement with the selected gears, the ratchet- s 338 and 336 are so disposed as to prevent reception of the pawls 332 and 334 so that pawl 328 cannot be removed from notch 326.

It is to be understood that this application is not to be limited by the exact embodiments of the device shown, which are merely by way of illustration and not limitation, as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
