To all fio/tom, it may concer/L Be it known that I, HARRY l. C.' Bnowivr., a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful improvements in Counting-Machines; and l do hereby declare the following to be :i full, clear, and eXactdescription of the invention, such as will enable others skilled in the art to which it appertains to nia-ke and use the saine.

My present invention relates to improve nieiits in counting machinesr of the type in which two or inore wheels, displaying numerals l, 2, et cetera to 9 and O on the periphery, are mounted side by side on a coininon central shaft. Y

More particular the objects oi my invention are: to provide a devicevor' the charac-` ter named which will furnish a continuons register of a cycle olf movement, such as iw-ivolutions, oit inechanisin'to whichv it ina-y be coupled, whether the said cyclebe reversed in direction or not; in which the setting of the counting wheels in their several positions around the central shaft is performed by means which are independent and corrective of the train actuating the wheels; in which the wheels may be readily reset to any desired reading; and 'of such design that a complete instrument oi' small size may be constructed thi"oughoutl of ineX- pensive, dependable parts.

To the accomplishment of these objects and such others as may appear'hereinaiter,

my invention comprises the novel construction and combination oi' parts hereinafter described and pointed out in the appended claims, reference being had to the accom,- panying drawings.

ln the drawings in which the same reference characters' designate like parts throughout the several views. Figure l is an end view in elevation of the device, a guard (if with opening 29, used to cover all the numerals except those appearing in the central line, is shown in Fig. l, but the construction and purpose of such lguard being; commonlyA understood, the guard is elsewhere omitted. Fig. 4 is a front view in elevation of Fig. l. Fig. 2 is a sectional view on theline e-c of Fig. l seen in the direction of the arrow, comprising-'only parts which are not suiliciently disclosed by Fig. l.V Fig. 3 is an isometric view of one of the counting wheels complete with ratchet and cam. Fig. 5 1s an isometric view oit' one of the pawls used for actuating the counting wheels. Fig. 6 is a diagram showing the action between the parts displayed in Fig. 2. Fig. 10 is an isoinetric view ot the central shaft on which the counting; wheelsare supported. Figs. 7 and 8 are respectively end and front assembly vieWs of llig. l0 and the bracket member .in which it is supported. Fig. 9' is an isometric view of the shaft which drives the mechanism with circular ca-ins in their p0- sition thereon. y y

Referring to the drawings; in Figs. 10, 'l' and 8, A Vrepresents a cylindrical shaft ot relatively large diameter, a and a are cylindrical bosses centrally disposed on the ends of A, and by means ot which A is supported in the bracket il. rlhe bracket H comprises the `two plane parallel wings i and 7L', of like shape and connected at the rear by the cross piece lt; the upper right hand `corner of 7i, Fig. 7, being broken away to display notch j in wing 71,. Holes f and f', lin and it respectively, receive bosses c and c respectively, when the wings of the bracket, which is preferably made oit' ,a resilient material as steel, are slightly spread apart. Holes ,Q/ and fa/ form bearings for a shaft Y, Figs; l and el. Returning to Fig.l l0, l, 2, 3, el. and 5 are sockets of cylindrical bore, uniform size and depth,and having their axes in the same plane and `parallel to each other; the plane containingy the axes ot the sockets, passes above the alisoi:l shaft A for reasons which will vbe explained under Fig. 6. A hole ,c/passing trom end to end of -shaii't A and paralleling' the axis thereof. forms a. bearing for the driving shaft B, Fig. 9. Fig. 3 represents a coinplete counting wheel, of which wheels five are used in thepresent machine: on the peripherjgf of the wheel appears the usual series of numerals or digits, viz; 0, 1 et cetera to 9 in order in the counter-clockwise Vdirection and at intervals of 36 degrees. The digits i'nay be printed for sight readily only or they may beV raised types for printing.V

-halls V, is such that in 21S "Il 'rises higher, until itltakes commaiul and throws the hall into'the approaching notch ahead ofv the action of the prime actuati means. By this action of the hall, the se.- ting of the counting wheels in their sei-'eral vangular positions, is made, independent and corrective of any variations in the length of stroke of the pawls.

ln Fig. 1, the. hraclrc ll'is attached to a plate hy rivets 18, tit the holes Q8, l? ig. 8; the plate and the spindle '19, are similar in appearance and function to the plate Q and the spindle Q shown. in the drawings of my Patent lo. 942,883 granted December 14th, 1909 aud entitled Huh odometers, to which art, among others, my present invention is adapted.

The operation of the counter is' as follows z-The revolution of the shaft B, with its cams 21 and engaging the slots 13 and 1e, causes the hail X to describe an angular movement about the anis of shaft Y. .fr line .e-e, joining the center of the shaft Y with the center of the paul shaft passe-1f;

through 'lo of thearc 'ar-ir when 'the hail attains the left hand limit, F l.` of this angular movement; and through te when at the right hand limit. vTheposition of rest of the counting wheels, determined by the position the pawls are retracted far enough to allow them to fall into the ratchet tooth notches; and the movement of the hail from position w to fw', provides traverse of the pawls needed to rotate the wheels throughV the angle of one tooth or digit interval. The .notch j in it', allows the pawl P5 to follow ratchet fr, to the end of the stroke. The provision of duplicate eccentric cams, engaging duplicate slots in the hail, propels the hail at each end thereof, which results in smoother and more uniform motion of the pawls than would he obtained with hut onel cam. Y

The action of toe counting mechanism proper as follows :-Pawl P5 remains in continuous engagement with the ratchet 715 of the units counting wheel, so that for each complete stro-lie of the hail, the unit counting wheel registers the net succeeding digit. Pawl P, however rides on the cam 0 carried bythe units wheel and therefore re# mains inoperative until the notch in c, 0ccurs in the position shown in Fig. 1, in other words, remains inoperative Vuntil the digit nine of the units wheel has assumed its place in the register sight, line ilO--ifl Fig. 4l. `When P, is allowed to drop, it engages the ratchet ff', attached to the tens wheel, and will traverse the latter through one tooth or digit interval upon the next forward bail stroke to fw', the units wheel meanwhile passing to digit 0. Thus the register will pass from 9 to 10, from 19 toV Q0, et cetera up to 89 when the next succeeding w position will register 90. This position of the tens wheel, presents the notch of cani c, to pawl P3, hut if E, were allowed to drop at this point into Aigagement with ratchet r3, attached to the hundreds wheel, the register would move to 191 with the next to posi tion of the bail. The lip 16 of P3, however, prevents the action alluded to in the following way. At registration 90, l?, cannot drop, the notch in 0 having been carried forward with the digit nine of the units wheel, hut remains in the inoperative or elevated position, and while it so remains sustains P3 also in the 'inoperative position through the lip 16, which overlies 13 as shown in Fig. 4f. lhen the units wheel again registers nine, will drop and engage r4, at the same time allowing P1, to drop and engage r., ratchet of the hundreds wheel. The lips 16 of the pawls to the left, Y

overlie the pawls to the right, hence the pawls to the left are supported by those to the right, so that?, engaging the thousands wheel, ratchet r2, must remain inoperative until the units, tens andl hundreds wheels Iall have assumed the position which presents their respective digits 9, in the line iO-i1; Likewise P1 engaging fthe ten thousands wheel ratchet c, must remain inoperative until the registration 9999 has appeared.

Thus a. vcontinuous registration progressing hy units is secured up to 99999, after which the register returns to 00000, and begins again to register upward.

Referring again to Fig. 6, it is to he noted that the degree of Obliquity of space 3 to circle Q. determines the direction and amount of the motive eEect of the forces Q/ fr and o o exertedhy the points o and v.respectively, upon circle V. Thus, if space 3 he made normal with respect to (al, the angles made hy ,r-fz/ v and o-Jv with the sides of 3, will he equal; and in consequence, forces exerted by points o and fv alike in etect upon circle V. Also,`as 3 recedes from the normal, the forces become unlike; that which is approached having less and less effect upon circle V, and greater and greater effect in resisting rotar tion between the counting wheel and shaft A... In an arrangement of 3 normal to Q, the counter wheels and shaft A. would loe rotatable with respect to one another with equal facility in either direction; in the arrangement shown. in the drawing the wheels andsha-ft have hut a single direction each, of rotation with respect to one an other. Between these extreme positions, however, the action ofthe balls to position Athe wheels undergoes no change. In the lio the sides of 3, is used primarily to make room for the operating; shaft B, but other relationship between 3 and Q might be advantageously used in several variations'o the present mechanism. Stiii other modificationsmight be made in the herein described. apparatus Which could be used ffithout departing 'trom the spirit of /iy invention.

Having thus described my invention, what claim and desire to secure by. Letters PatH nt of the United States, is:

l. In a coimting` machine, the combination ot a cylindrical sui.i ,ting member, oi? a countine' Wheel han/ing;` a central bearing and rotataoiy mounted on said member, the inner wail of the bearing of said Wheel being1 provided with arcuate notches spaced a uniform distance apart, therearound, mechanism operatively connected with said Wheel, and imparting successive partiairotations thereto, and in ans contained Within said member, and intei posing a yielding resistance to the rotation of said Wheef upon said member in onedire tion, when actuated jy' said-mechanism, said means seating in said notches successiyeij,T and ioeking said Wheei against rotation relative to said meinber in the opposite direction.

2. In a Counting` machine, the combination oit a supporting member, an indicating Wheel, having a bearing and rotatable upon said member, the bee-ringwail ofsaid Wheei being` provided with a plurality otnotches, spaced a uniform distance apart around the Wheel and forming; projections between said notches havingsloping sides, a mechanism for rotating the Wneei in one direction, a yieldably mounted means contained Within said member, and seating in said notches Vsuccessiveiy as the wheel is rotated, said means locking the Wheel against rotation relative 'to said member in the opposite direction, said means operating against the rear side of each projection after it has passed the iine ot movement of said means, to accelerate the Wheel movement independent of said mechanism.. v
