COUNTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,773, dated November 16, 1897.

Application filed January 23, 1897- Serial No. 620,392. (No model.)

To all whom it may concern.-

Be it known that 1, ROBERT MIEHLE, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Counting-ll/Iachines, of which the following is afull, clear, and exact specification. I

Myinvention relates to that class of counting-machines or registers for indicating the impressions made on printing-presses or the number of operations or movements of other forms of machinery or their parts; and it has more especial reference to that type of counting-machines in which are employed a series of disks, which for convenience may be termed digit-disks, bearing on their peripheries the nine digits and one cipher, and means revolving in unison with such disks and actuated to impart the movement of one disk to the next succeeding-disk in the series.

One of the objects of my invention is to provide a counting-machine comprising the minimum number of simple parts which shall be of such form and arrangement as-to greatly reduce the cost of manufacture and the liability of the machine getting out of order.

A further object of my invention is to so construct and arrange the part-s as to enable the use of coil-springs wherever a spring or cushion is desired, and thus avoid the serious defect heretofore existing in counting-machines due to the blade-springs employed losing their flexibility or form after being in use a comparatively short time.

Another object of my invention is to impart the movement of one digit disk or wheel to the next succeeding one through the intermediary of positive means as contradistinguished from springs, and, further, to so multiply or gradually increase throughout the series the initial movement of the first of such means in the series that the last such means shall have the same movement as the first, or at least a sufficient movement to enable it to engage and operate the next disk, notwithstanding the lost motion in bringing the engaging surfaces of the said means into contact.

I/Vith these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts whereby the said objects and certain minor objects hereinafter appearing are attained, all as fully explained with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a front elevation of my improved counting-machine,

tional view taken on the line 5 5, Fig. 1. Fig.

6 isa similar section taken on the line 6 6, Fig. 1. Fig. '7 is a side elevation of one of the digit-disks. Fig. 8 is a sectional view of such digit-disk, taken on the line 8 8, Fig. 7, also illustrating the relation of such disk to two of the others. Fig. 9 is a diagrammatic view of the levers which impart the movement of one disk to the other, showing them in their normal position; and Fig. 10 is a similar view showing the levers in their engaging position.

The operating parts of my improved counting-machine are preferably arranged within a closed casing 1, which also serves as a support for the main shaft or pintle 2, mounted in the ends of the casing 1. Arranged loosely on this shaft or pintle 2 within the casing is the series of disks 8 4 5 6 7, each of which represents the nine digits and one cipher and which for the sake of convenience I have herein termed the digit-disks. Any number of these disks may of course be employed, according to the capacity of the machine desired, and each is preferably provided around its periphery with a widened band or flange upon which the nine digits and cipher are indicated, so that by forming openings 8 in the casing opposite each disk the progress of the registration may be observed.

The digit-disks are independent of each other and revolve loosely upon the shaft 2,

and each is provided with an extended hub or boss 9, which abuts against the hub or boss on the adjacent disk, and thus holds the disks the requisite distance asunder. Each of the disks on one side is provided with a series of lugs or teeth 10, which are ten in number and correspond in relation and arrangement to the characters or numbers on the periphery of the disk and which serve as means whereby motion or intermittent rotation is imparted to the disks to bring their numbers or characters successively opposite the openings 8 in the casing. Motion is imparted to the units-disk, which is of course the first one in the series on the right, bya pawl 11, which is of sufficient length to rest normally upon one of the lugs or teeth 10 of the units-disk and to be permanently in position for engaging with the next one of such lugs when the pawl is advanced, the end of the pawl being preferably notched or curved, as indicated in Fig. 5, so as to avoid slipping out of engagement with the tooth or lug 10. Arranged under the series of lugs 10 on each of the digit-disks is a combined holding-dog and alining-cam 2, pivoted upon a cross-pin 13, mounted in the ends of the casing 1 and each provided with a wedgeshaped or double-beveled cam l-l, whose apex is. adapted to engage between each pair of the lugs 10 as the disks are rotated. These combined holding dogs and cams 12 14: are each provided on their under side with a pin 15, inserted in the upper end of a coil-spring 16, whose lower end is socketed in a perforation 17, formed in a plate 18, resting upon the bottom of the casing 1 and being held in place by the simple means consisting of a ing 19 at each end passing through an aperture in each end wall of the casing and held in place by the front plate 20, which is itself removably secured in place by a pin 21, passing through the ends of the casing and through perforated cars 22, formed on each end of the inner face of the plate 20. By means of this pawl 11 and the double-inelined alining cam 14; it will be seen that when sufficient movement has been imparted to either of the digit-disks to cause one of the pins or lugs 10 to pass over the apex of the cam 14: the incline on the other side of the cam under the influence of the spring 16 will continue the rotation of the disk until the apex of the cam is midway between the two lugs bearing against the inclined surfaces and at such time the proper digit or cipher will be directly opposite one of the openings 8 in the casing and alined with the others on the succeeding disks. The advantage of this, it will be seen, is that it is not necessary that the movement of the pawl 11 be gaged to a nicety so long as it is sufficient to push the lug or tooth 10 over the apex of the cam 14, and in adapting the machine to universal use on diverse forms of machinery this feature is a great desideratum and cannot fail to be appreciated when it is taken into consideration that the moving parts in the various forms of machinery to which the eountingmachine may be attached will vary widely in their extent or degree of movement, and consequently great annoyance and difficulty would arise should it be necessary to depend upon the movement of the pawl 11 for the requisite and entire movement of the digit-disk.

The heel of the pawl 11 is provided with a perforation into which is inserted a pivot-pin formed on or secured to the inner side of one end of a lever 2t and projecting through a slot or opening 25, formed in one end wall of the casing 1. The pawl 1.1 is sleeved loosely upon the pin 23, and it is held from inward movement or from slipping olt' such pin by the face of the disk 3, as will be understood from Figs. 1 and 3, and it is prevented from rising sufficiently far to slip over the periphery of the disk by the top of the casing. The outer side of the pawl 11 is provided with a pin or lug 20, to which is attached one end of a coil-spring 27, whose other end is connected to a ing or hook 28, formed on the upper side of the arm 24-, thus holding the pawl normally down in engagement with the teeth or lugs 10. The arm 24: is provided with a squared or angular boss 29, (shown in dotted lines in Fig. 3,) which is pierced bya protruding end of the shaft 2 and upon which shaft the arm 21 oscillates. This angular boss 20 forms the means of attachment of the actuating-arm 230, whose hub 2-31 is slipped over the boss 20 and held against displacement by a collar 32, secured to the end of the shaft 2 by a set-screw 33 or other suitable device, the arm 30 being provided with a series of perforations 31, whereby it may be attached to the part of the machine whose movements it is desired to count or register. In order that the pawl it may be returned to its normal position and the arm 30 raised without depending upon the return movement of the part of the n'lachinery to which the arm is connected, one end of the lever 24: is provided with an inwardly-projeeting pin 34-, upon which is pivoted the upper end of a rod 35, passing through a coilspring so and having a shoulder 37 hearing against the upper end of such spring, while the lower end of the latter passes through a perforated car 38, formed on one end of the faceplate 20 and through which car the rod passes, as clearly indicated in Figs. 1 and 3, so that when the arm 30 is depressed the spring 36 will be compressed, and when the pressure upon the arm 30 is released the spring will return such arm and the pawl 11 to their normal positions. The lever 2i, car 38, and rod are so disposed that the leverage of the end of the lever 24-, which effects the compression of the spring St, will gradually increase with the downward movement of the arm 30, and the resistance of the spring :3 to the downward movement of such arm 3 will consequently be uniform substantially throughout the entire stroke of the arm 3U and thus avoiding the necessity for employing a very strong spring .in order to get the requisite tension at the final end of the return stroke.

Each of the digit-disks is provided with an aperture 30 and upon one side with a pair of bosses 40. Arranged between and pivoted to the bosses 40 on the units-disk 3 is a lever ll,

whose end opposite the opening 30 is provided with a lateral. projection L2, which protrudes through the opening and extends from the'right-hand side of the disk or toward the adjacent end of the casing, while the opposite side of such lever 41 is provided with a projecting edge 43. Secured to the end of the casing 1 is a stationary cam 44, which is arranged in the path or line of rotation of the projection 42, and with the inclined face of which the inclined edge of the projection 42 engages at each complete rotation of the units-disk, and thus forces the edge 43 of the lever 41 to the left and causes it to engage with one of the pins or lugs 10 on the next disk 4, which is the tens-disk. At the ninth stroke of the pawl 11 the projection 42 is carried over or opposite the flat surface 44 of the cam 44, and while in this position the edge 43 is in engagement with one of the pins on the disk 4. When the pawl 11 makes its next stroke, the projection 42 will be carried across the flatface 44 without permitting the projection 42 to recede to its normal position protruded to the right, and while so passing the face 44 the edge 43 of the lever 41 will impart a tenth-rotation to the disk 4 and if the disks have been properly set will bring the first digit or number 1 opposite the opening 8 and in line with the cipher on the disk 3, which advances a tenth-rotation with the disk 4, and thus registers ten downward strokes of the arm 30. The cam 44 may be secured to the end of the casing 1 in any desired way; but I prefer to form such cam on a hub-like portion 45, through which the pin or pintle 2 passes. This hub 45 is provided with atongue 46, which fits in a complementary slot formed through the edge of the end of the casing, as shown in Figs. 1, 3, and 5, and which tongue and slot hold the hub 45 and cam 44 from rotating on the pin 2. For the sake of greater strength the outer side ofthe tongue 46 may be provided with a lip 47, projecting downwardly against the face of the end of the casing and thus holding the tongue and hub 45 against inward movement. The boss or hub 9 of the disk 3 may, if desired, be let into the hub 45, as indicated in Figs. 1 and 5.

Between the lugs 40 and in the aperture 39 of each of the succeeding disks is pivoted a lever 48, (see Figs. 6, 7, and 8,) each of which is provided on one side with a projection 49, which extends laterally to the right through the opening 39 and on the other side with an edge 50, which is elongated in the plane ofoscillation of the lever on which it is formed. The proj ection49, however, is arranged nearer to the pivot of its lever than the outer extremity of the edge 50,"and such projection 49 is preferably elongated transversely or substantially transversely of the edge 50. These projections 49 and edges 50 are the same on all of the levers 48, with the exception of the projection 49 on the tens-disk 4, whose edge or surface is slightly rounded, as clearly indicated in Figs. 1 and 8. All of the levers '41 48 are held in their normal positions with the projections 42 49 protruding from the right-hand side of their respective disks by means of coil-springs 51, interposed between one end of each of the levers and the disk to which it is pivoted, the under or inner side of such end of the lever being provided with v a pin or lug 52, entering one end of the spring 51, while the side of the disk is provided with a countersink 53, in which the end of the spring is seated, and a central pin 54, which enters the spring.

The ends of the levers carrying the edges 43 50 are located directly opposite or under the cipher on each disk, and in the use of the machine all of the ciphers are arranged in line opposite the openings 8 in the casing, and when so arranged they will be one-tenth of a rotation past or this side of the flat surface 44 of the cam 44. Consequently when the beveled projection 42 reaches the cam 44 on the ninth stroke it will force the projection 42 to the left and cause the edge 43 to engage with one of the pins or lugs 10 of the unitsdisk 3 and the next or tenth stroke will carry figure 1 on the latter disk, which is adjacent to the pin or lug 10 thus engaged, opposite the opening 8 in the casing. The disk 4 will thus receive a tenth-rotation at each complete rotation of the disk 3,and all of the other disks will remain at restuntil the projection 49 on the disk 4 and the beveled projection 42 have arrived at a position in line with the plain surface 44 of the cam 44, whereupon such cam having forced the beveled projection 42 to the left and crowded the edge 43 against the projection 49 the lever carrying the projection 49 on the disk 4 will in turn crowd its edge 50 over into engagement with the pin 10 corresponding to the figure 1 on the hundreds-disk 5, and as the arm 30 continues to descend the three disks 3 4 5 will rotate in unison as long as the beveled projection 42 is in engagement with the plain surface 44 of the cam 44, and in so rotating a tenth-rotation will be imparted to the hundreds-disk 5 as well as to the

disks

3 and 4, and the numeral 1 on such disk will be brought down opposite the opening 8, thus registering one hundred downstrokes of the arm 30. As soon as the beveled projection 42 has cleared the surface 44 the springs 52 will return the levers 41 48 to their normal positions, and the levers will be free to rotate or revolve with their respective disks without engaging with any parts of the adjacent disks until another complete rotation of the units-disk has been accomplished, whereupon the edge 43, carried by that disk, being forced to the left at each complete rotation, will successively engage with one of the pins or lugs 10 on the disk 4 11 will crowd the edge 50, carried by the disk 4, against the pin 10 corresponding to the numeral 2 on the'hundreds-disk 5, and thus impart a tenth-rotation to such latter disk, and as soon as the surface at is cleared by the projection 42 the parts will resume their normal position, as before explained, and the rotation of the two disks 3 and 4t will continue at the ratio of ten to one without molesting the disk 5, excepting at each tenth-rotation of the disk i, and after the disk 5 has received nine such partial rotations its projection 49 will have arrived at a position in line with the cam 4i and the projections 4-2 40, carried by the disks 3 and l, and as the projection 4:3 rides up the cam ll the edge 50, carried by the disk l, will be forced against the projection lfhearried by the disk 5, and consequently the edge 50,carried by the disk 5,will be projected between two of the pins carried by the next disk or thousands-disk 6, and as the arm 30 completes its downward stroke the beveled projection will slide across the plain face ll? of the cam et-it and the disk (3 will be compelled to rotate in unison with the disks 3, i, and 5 for a tenth-rotation, or until the projeetion L2 is no longer crowded to the left by the cam it.

Having thus described the operation of the device up to the thousands, the operation of the remaining disks will be readily understood, and it will also be seen that the c011- tinued operation of the machine will eventually bring all of the ciphers together and opposite the openings in the casing 1; but should it be desired to reset the disks at an earlier or any other stage any one of the disks from 4- up maybe rotated in either direction by the thumb, and the units-disk may also be similarly rotated by raising the pawl 11 b y means of the projecting pin 20.

The purpose of rounding or beveling one edge at least of the projection 49, carried by the tens-disk 4, it will be seen is to enable the projecting edge 43 of the tens-disk to engage therewith and force it inwardly or to the left while the tens-disk is still moving, it being understood that should such edge be straight or squared, like the edges a9 50, carried on the succeeding disks which come opposite each other before actual engagement, the edge 45, carried by the units-disk, would hang on the projection L9 without deflecting the latter to the left. The corner of the edge 4-2 is beveled off to enable it to sooner start in between the pins 10 without engaging the wrong one. It will also be seen that in order that the disks may be free to rotate without liability of frictional contact with each other or with any of the parts carried thereby it is necessary to have more or less lost motion or space between the projection 4:9 on one lever and the edge 50, carried by the other lever, and that ordinarily this lost motion between the parts would entirely consume or take up the move ment of the projecting edge 4-3 of the first lever or one carried by the unitsdisk, so that the movement imparted to the succeeding levers would be gradually decreased and ultiteav're mately become insullicicnt to project the edge 50 far enough to engage between the lugs or pins 10 on the succeeding disks. In order that the movement of the first lever therefore may be multiplied upon the second and that of the second upon the third, and so on throughout the series, to a sullicient extent to compensate for the lost motion between the engaging parts, I employ the described relation of the projections 1-9 and edges 50. The principle of this operation may be best understood from the diagrams shown in Figs. 9 and 10. In these figures I have designated all of the projections on the right-hand sides of the lovers +t1 48 with the numeral it? and all of the edges on the left-hand sides which engage with the pins 10 with the numeral 50 for the sake of convenience. In Fig. 9 the first are shown in their normal position with a slight space between the projections l0 and edges 50, and in Fig. 10 they are shown in their engaged position or the position that each lever assumes when pushing its companion lever into a position for engagement with the pin or lug 10 on the next succeeding disk. lVhen the first lever ll is oscillated to the left, its edge 50 nearest its pivotal point or fulcrum will engage with the projection 40 on the next lever 48, and as the lever ll continues to move to the left the projection 49 on the lever -l8 and the edge 5001: the lever ll will make relative movements which will bring the outer extremity of the edge 50 against the projection 4-9, and in this way the long stroke produced by such outer extremity of the edge 50 will be imparted to the lever 48 at a point nearer to the fulcrum of the lever 48 than the engaging-point of the edge 50 on the lever i1 is to the fulcrum of such lever 41. Hence the lever ll will more farther at its outer end than does the outer end of the lever &1 after contact; but this additional movement is lost orbroken up in the space between the first and second levers -18, and consequently the movement of the first lever 4C8 after it touches the second lever it will be only equal to the movement of the lever l1 after the latter engages with the first lever l8. Hence, while each lever in the series after the first receives from its companion a movement which is greater than the movement of such companion whilein contact therewith, such increased movement, being proportioned to the space between the lovers, is consequently absorbed by said space, and as a result the increased movement is not manifested in the third leverlrom any given starting-point and all the lovers move the same distance.

The front of the casing 1 is provided with a hinged cover 51, which opens upwardly and. in which the openings 8 are formed. This cover is provided with a fastening consisti' 3 of a catch 52, which engages over a teeth :3 on one end of the cover, and adjacent to which tooth is formed a thumb-piece 5- by means of which the cover may be thrown upwardly,

the catch being simultaneously disengaged from the tooth 53 by a thumb-piece 55, formed on the catch 52, so that by one movement of the thumb the catch is disengaged and the cover raised. The catch is pivoted upon one end of the pin 21, which comes through the end of the casing 1, and the lower end of the catch is provided with a projection 56, between which and an ear 57, formed on the plate 20, is interposed a coil-spring 58, one-end of the spring being let into the projection 56,

.while its other end surrounds a pin 59, formed on the inner face of the ear 57. The outward movement of the catch is limited and the spring 58 prevented from jumping out of place by a shoulder 60, formed on the catch and engaging on the top of the ear 57.

61 represents perforated flanges for convenience in attaching the machine to any suitable support, and 62 is an extended portion of the casing forming a hood over the slot 25 in the end of the casing for excluding dust.

The pivot-pins 40, which pivot the levers 41 48 between the lugs 40, are held in place at one end by the pintle or pin 2 and at the other end by a cross-pin 40, the lugs 40, as well as the hub or boss 9 of the disk, being bored straight through, as shown at 4:0 in Fig. 7. Hence it will be seen that when the pin or pintle 2 is removed the pivot-pin 40 may be driven out. endwise by inserting an instrument in the outer end of the bore 40",

the pin 4:0 being slightly smaller than the bore 40 so as to leave a space for the passage ofthe punch or ejecting instrument.
