INDICATING AND CALCULATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 388,518, dated August 28, 1888.

ApplieationtlerlDeeember18, WSG.

To all whom, it www! concern:

Be it known that l, lniLir You, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in indicating and Calculating Machines; and I do hereby declare that thc following:r is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being` had to the aeeompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to indicating `and calculating machines; and it consists in the conA struction and combination of parts hereinafter particularly set forth and elaimed.

In the accompanying drawings,Figurel represents a perspective view of an indicating and calculating machine embodying my in vention. Fig. 2 represents a vertical trans verse section of the same from front to rear, partly broken away,looking toward the toothed wheel O, hereinafter described, the keyframe being in its highest position. 14`ig. il represents a view similar to Fig. 2. except that the toothed wheel C is partly broken away and the key-frame in its lowest position. Fig. 4 rep resents a detail view of the laterally-movable bar U, its supportingdevices, from which it is slightly separated in this ligure, and a part of the spiral hereinafter described. Fig. 5 represents a detail view in rear perspective of the key-frame, the supplemental frame attached thereto, and certain additional devices. Fig. represents a partial transverse vertical section ofthe wheel (l, spiral (Y, and shaft M, with some other parts being shown in elevation. Fig. 7 represents in detail perspeetive the sliding pin which operates the laterally-moving bar U. Fig. S represents one ofthe keys in detail perspective. Fig. tl representsin detail the two spring-pressed pawls l and 2 and the key-frame and shaft whereby they are su pported, a part of the toothed wheel (,l being shown in outline. .Figa l() represents a similar View in elevation taken from the other side, the devices for automatically locking the toothed wheel at the end of the downward Serial No. 222,011. (Model.)

movement of the key-frame being shown in part also. Fig. 11 represents the computation-wheel in detail elevation, with the indicator-platc and means for turning the latter back to zero, said means being partly in vertieal section. Fig. 12 representsa detail plan view of the indieator-plate, the'stem thereof being in erossseetion. Figs. I3 and 14 represent enlarged detail plan views of the bar U, the arm Q, and the spring-pressed pin l, with a part of toothed wheel C shown in section, the former View being taken when the said bar is moved sidewise by said pin, the latter when it is in its normal position. Fig. l5 represents the bar U, pin l, and a part of wheel tl in side elevation.

A designates the frame of the machine, consisting of two upright side castings, which are fastened to a suitable bed. These side plates or castings have bearings formed in them for two horizontal transverse shafts arranged in the same transverse vertical plane, the upper shaft being marked M and the lower one rlhe computation-wheel consists of the spiral C and a toothed wheel, (l, attached thereto by studs c, so as to leave an intervfniing space, c. The spiral has its periphery graduated in figures from Oto 99. The computation-wheel as a whole is fast on shaft N, and of course turns therewith. '.lhe teeth of wheel C are beveled on their forward face, using this term with reference tothe direction of rotation of said wheel. They admit between them two spring-pressed pins or pawls, l and 2, which are similarly beveled on their upper sides and mounted in a vertically-vibratory key-frame, l. The downward motion of said frame causes a corresponding partial rotation of said wheel by reason of the engagement of said pawls with the latter. When the keyframe is to be raised for another impulse, the said pawl 2 is first withdrawn by hand from such engagement, the pawl l being automatically withdrawn by the return of bar U, hereinafterdescribed. 'lhiskey-frameispivotedon shaft N and provided with an adjustable counterbalan(1e-weight, l. A toothed segment, ll, rigid with said key-frame l, meshes with a pinion, Bi", formed with a sleeve, M, turning on shaft M. rthis sleeve also carries an IoO indicator-wheel, J, provided on its periphery with two parallel series of' numbers in large type, those ou the right being visible through the i'ront window of the ease and those on the left through the back window of the case, these two series being arranged in reverse or der the one tothe other. Shields m are normally held between these figures and the windows, said shields being carried by the ends ot' a bar, K, turning on sleeve hl, but provided with a coiled spring,l\", which ordinarily holds it horizontal. From this bar a rod, l, extends down to a long arm, tg, ot' a vibnatoryY frame, E, mounted on a fixed shalt. ll, under frame ll. This frame lfl is provided with a shoulder, lf', which engages with and locks the toothed wheel C when said frame ll is depressed. The frame B is normally locked by a fixed plate or flange, lli, which is raised from the bed of' the machine, and an arm, (l, extending downward into contact with said plate or flange f'rom a supplemental frame, F, mounted on a transverse shaft, l, the latter being fixed inthe key-frame?. Ou this shaft I a series of keys, l, is individually pivoted, each key being provided with a rearwardlyextending end below the rear cross-bar, l, of supplemental frame F, so that the depression of' the front end of a key will result in lifting said cross-bar 1/ and rocking said frame F correspondinglyon its pivot. llach key has also a downwardlyextending arm, provided with a shoulder, g', arranged to come in contact, when lowered a predetermined distance, with the rear cross-bar, H, of pivoted frame E, thereby rocking said frame. The independent downward motion of' the tront end of' each key is limited by the keyrf'rame l.

The frame lil is normally locked by a flange,

. U', raised under the rearwardlyextending arm Q of' said frame. This flange forms part of a laterally-movable bar, U, which is supported by its stud u in a lateral slot, d2, of' aplate, D2, rigidly attached to the frame A.. Said bar U extends upward in a curved line into the space between the graduated spiral and the toothed wheel C. It has a peripheral recess, U2, near its upper end, the material at the lower inner corner ot' which is rounded or beveled at u, Fig. 4. This rounded corner receives the oblique lateral impact ofthe cors respondugly-beveled point u of' the springpressed pin l, already .referred to as carried by frame B. There are thus independentlocking devices for the key-frame and for the toothed wheel, and devices which operate the shields m, and these are successively unlocked by thc downward pressure ol' the operator-s finger on any one ofthe keys.

A plate, D, attached to the frame A has a gravity-paw] pivoted to it, which engages with the teeth of wheel C and prevents said wheel and the spiral from turning backward. A spring -pressed friction rod, D", works through said plate and bears against the spiral (l, locking the machine until withdrawn hy hand. After withdrawal it is held out of' contact with said spiral by stu ds d on the sides of' said rod, which come in contact with the outer end of a fixed tube, ll, which ineloses and guides said rod Dil. Thesaid tube is longitudinally slotted at d'l inward from said end, to allow the said studs and rod to be drawn out and turned for such locking.

The fixed upper shaft, M, has au arm rigid therewith, which has a tubular bearing, T, formed in its end. This has a recess, t, on its inside, which is engaged by a lug, s, formed with a. small bar, S, pivoted within a stem, R, and forced by a spring, n, into such engagement. This stem, recessed on one side to receive said pivoted bar, extends through said tubular bearing, and bears at its lower end an indicator disk or plate, T', provided with a circular series of' openings, 6, near its edge. These openings successively expose the successive figures on the periphery ot' the spiral C. the plate or disk heilig turned by the contact of' said rotating spiral with downwardlyeX- tending crown teeth 5 ot' said disk. By foro ing inward said bar a it is disengaged from bearing T, so that the plate or disk may oe turned back to Zero. Its edge or peripheral part is graduated between the openings (l.

The operation ot' the machine is as follows: The graduated spiral (1 and the indicatorplate T both are set at zero. One ofthe keys is then pressed by the operatorsfinger, so that its rear end will lift the rear erossbar ofsupplemental frame F. This causes said supplemental frame to rock on its pivot-shaft l and removes the arm (l from contact with fixed plate lli, thereby leaving key-f`ramc Il at liberty to rock downward. The continued pressure of said key causes this downward rocking ot' said key-trame. rlhc obliquely-beveled pin 1, carried by keyframe l, sinniltaneously moves the har U laterally by the contact of its obliquely-bevcled point with the correspondingly-beveled lower inner corner, u2, of' the material bounding recess U2. This lateral shifting of' bar U removes the lockingllange U from under the rear arm, t), of the lower frame, F. Simultaneously the pawl 2,carried by keyl`rame ll, engaging one of the teeth of wheel (l, turns said wheel and the spiral C', and this latter turns the indicator plate or disk T, as before stated. The downward motion of frame ,l continuing and the supplemental frame F being carried thereby, the arm G of' the latter frame soon comes in contact with the rear cross-bar ol' frame 1G. rocking said frame backward, so as to put its shoulder E into contact with one of the teeth C, thereby locking said wheel. The depression of rigid arm U as said frame l rocks backward pulls rod L downward, and thereby rocks the arm K, so as to remove the shields m from the fig ures of wheel J which at the time are opposite the front and rear windows of the case.

These figures are determined by the length and shape of the arm G or the position there on of the shoulder g', since the segment lil, moving with the vibrating key-frame vl3,turus the sleeve M andthe wheel J during the downward motion of said frame, and since this motion is greater or less according to the distance traveled by said arm G before coming in eontact with the lower frame, ll, and causing its flange E to engage the wheel (l. As the keys will have the shoulder g at different distances from their lower ends, the depression of each key will cause a ditl'erent figure of wheel J to appear through the windows of the ease from that which would be exhibited by similar pressure on any other key. This difference in their action ou wheel J would be paralleled by the corresponding action of the keys and intervening parts on spiral (V and indicatorwheel ,l", which are equally controlled in their forward motion by the tilting of frame l". After cach depression of key-frame ill the machine is automatically locked against upward motion by the spring-pressed pawl 2, the end ot' which then comes in contact with the unbeveled upper side of one of the teeth of wheel C. \Vhen this pawl is withdrawn by hand, the key-frame may be raised, the pawl 1 riding upward free of the teeth of said wheel. All the parts then return to their original position, except the wheel (I, the spiral (1, the shaft N, the indicator-plate l`/, and the stem T. All of these parts have been advanced more or less to a predetermined extent, and this advance they do not lose, it being with them a stepbystep motion forward until intentionally turned back by hand. At cach downward motion of key-frame 'l the rotary step-bystep motion of indicator plate 'll' is but very slight, since a complete revolution of spiral C moves the said indicatorplatc only through the distance indicated by one numeral of its series. Thus said indicater-disk is in function a hundrcdswhcel, the spiral C taking' the place of a unit-wheel. (')f course the keychoscn for cach impulse will correspond to the sum which is to be registered. '.lhis will be shown bythe numeral cxposed on each side of wheel J, and the same numeral or numerals indicating the same advance will appear on the spiral C' through one of theopcnings in theindicator-plate 'll'. lhc return ot' the bar U to its original position as the kcy-frame rises is effected by the action of a replacing spring, n, and this also withdraws the pawl or pin 1 from engagement with wheel (l, as already stated.

1. The combinationofthepivoledkey-frame with a key, ll", pivoted thereto, a supplemental frame, F, pivoted to frame l and arranged to be rocked by said key, an arm on Said supplemental frame, a fixed plate engaged by said arm to lock said frames B F until said key moves said arm out of the way of said plate by rocking the frame F, a wheel bearing numerals on its periphery, and intermediate devices whereby said wheel is operated by said frame, substantially as set forth.
