To all whom it may concern:

Beit known thatI, l-InRvnY D. GANsn, of St. Louis, Missouri, have madea new and useful Device for Operating a Set of Levers, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part ot' this specilication, in which- Figure 1 isa view in perspective ot'a device; Fig. 2, aplan; Fig. 3, a side elevation; Fig. 4, a longitudinal vertical section upon an enlarged scale, taken on the line 4 4 of Fig. 2; Fig. 5, a similar section, the parts being as when a key is depressed; Figs. 6 to 23, details upon various scales, Fig. 6 being a front elevation, partly in section, showing the mechanism for operating the slides; Fig, 7, a bottom view oi' the slides; Fig. 8, a view from the front, showing the means for adjusting the rockframe; Fig. 9, a view vfrom the front, showing the means for adjusting the slides transversely in the device; Fig. 10, a side view of one of the tumbler-rods; Fig. l1, a view in perspective of the forward end of a tumblerrod; Fig. 12, a view iu perspective of the rearward end of a tumbler-rod, the rod having the pendant attached; Fig. 13, a sectional view ofthe part to which the tumbler-rods at their inner ends are jointed; Fig. 14, a view in perspective 'from the rear of the part last referred to; Fig. 15, a view in perspective, showing the mode ol' hinging the levers; Fig. 16, a top view of the slides upon an enlarged scale, the slides, for the purpose of illustration, being spaced apart more than in practice is necessary, and the positions of the tumbler-rods being indicated by the crosslines; Fig. 17, a view in perspective ofthe slides; Fig. 18,21. view in perspective showing the slides in part, and showing a tumblerrod ready to fall when the slide D2 shall have been moved to the right; Fig. 19, a crosssectiou ofthe part shown in Fig. 18; Fig. 20, a view in perspective showing the parts exhibited in Fig. 18, but the slide D2 is moved to the right and the tumbler-rod is in the notches in the slides; Fig. 21,a cross-section of the parts shown in Fig. 20; Fig. 22, aview in perspective of the slides in part, (two, D2 and D3, ofthe slides must be moved to the right before the tumbler-rod can fall;) and Fig. 23, a view of the parts shown in Fig. 22,

but the two slides D2 D3 have been moved to the right and into position for the tumbler-rod to drop. y Figs. 24 and 25 illustrate a modication in the construction of the slides and tumbler-rods.

The same letters denote the same parts.

rllhe aim of the present invention is to provide for moving any one, as desired, of a set of levers by means of one or more of another set of levers, the levers of the operating set being less in number than those of the set operated upon.

The invention is adaptable to various mechanisms which have a number of levers or parts requiring to be separately moved-type-setting or telegraphing mechanisms, forinstance. It is especially valuable iu connection with a type-writing mechanism, as it enables the operator with, say, half a dozen levers to accomplish all that is now feasible with the ordinary type-writer, the key-board of which contains as many levers as there are types to be moved. y

Considered generally, the device consists of the set of operating-levers, a set of independently-movable slides, a set of movable tumbler-rods, and the set of levers operated upon. The slides in number correspond to the operating-levers, and the movement of the siides are responsive to the movements, respectively, of the operating-levers. The movements of the tumbler-rods are determined by the positions of the slides. The tumbler-rods in number correspond to the levers operated upon, and the movements of the levers operated upon are dependent on the movements, respectively, of the tumbler-rods.

In the drawings, A represents the base of the device.

B B2 B3, Ste., represent the levers to be moved, and C C2 O3 C* C5 C the levers for effecting the movement of the first-named levers.

rlhe operating-levers C C2, Snc., can be considered and hereinafter will be styled keys,77 the operators hand being applied to the forward ends, c 0, of the keys as to the key-board of a type-writer, causing the ends c c to be depressed as desired, and through the mechanism hereinafter described producing the desired movements of the levers BB2, 85o. The

keys O C, 85e., turn upon a fulcrum, a..

IOO

Springs c act to recover the keys when the ends c c are released by the operator.

D D2 D3 Dl D DG represent a set of slides. They are arranged transversely in the device, and they are supported so that they can be independently moved endwise a short distance to the right. In the present device the slides rest at their ends upon the posts Fi E. These posts are arranged one at each side ofthe device, and are attached to and extend upward from the base A. The posts also serve, by means of b ackcts j", to support a cross-bar, F. The slides longitudinally in the device are confined by guides c. The endwise movement of the slides is limited by the stops G G', Figs. 1, 2, 3, 9. The stops, by means of the screws g, are made adj nstable for the purpose of adjusting the termini of the movement of the slides.

H H represent another pair of posts, which are att-ached to and extend upward from the base A at each side thereof.

l represents an oscillating frame, which at z' 'i' is hinged to the posts H H, and which extends thence toward the rear end of the device, the rear end bar, fi', coming in the rear of the slides D D, &c. r1`hc forward end bar, i2, of the frame, in connection with the plates t il", serves to support and hold the forward ends of a set of so-called tumbler-roda7 J' J J, 'Ic., but in such manner that the rear ends of the tumbler-rods and the rear end of the oscillating frame can, when desired, be opened slightly apart. The tumbler-rods toward their rear ends pass above the slides D D?, &c., and rest in a slotted guideplate, if', which is fastened to the bar i.

The shape of the tumbler-rods is shown in Figs. 10, 11, 12, and the inode of connecting the rods and the parts i2 i t" is shown in Figs. 4, 5, 13. Reference in this respect is also had to Fig. 14. The rear ends of the tumbler-rods project through the slotted guide-plate i, that is attached to the bar fi, and beyond the plate 'i5 the rod ends are extended to project above and beyond the cross-bar F', and at their extremities are provided with pendants j, Figs. 3, 4, 5, 12. The oscillating frame at its forward end is counter-balanced, the counter-balances 'if' fi being attached to the arms i7 il, which project forward from the frame, as shown more distinctly in Figs. 1, 4, 5. The counter-balances are adjusted perfectly, so as to j ust overcome the weight atV the rear end of the oscillating frame and lift the tu mbler-rods out of the slides, it being my intention to render the oscillating frame sensitive to the force used in depressing its rear end. Springs, such as is, may be used in connection with or in place of the countenbalances. The springs lead from the posts H H to the arms i The osciilating frame is also provided with an arm, i, which extends from the bar i downward, and at its lower end is furnished with a bearing, il, which 's preferably in the form of a friction-roller and vertically adjustable upon the arm if.

K represents a rock-frame which is attached to and which rocks upon the bearing k. The frame is extended from the bearing horizontally and vertically, the horizontal portion lo being furnished with a cross-bar, It", upon which the keys C ji, ttc., when depressed, strike. From the bar 7:. an arm, It, extends upward and forward and so as to encounter the roller il as the rock-frame is turned on the bearing 7a. The arm at its extremity is supplied with acurved rub plate, 7a", the rub-plate being adjustable upon the arm if to enable the rock-frame to properly move the oscillating frame, as hereinafter described. The vertical extension ki of the rock-frame serves to impart motion to the pendants, as hereinafter described.

Springs, L L, at each side of the device and extending from the bar k2 upward to the posts F/ E', serve to uphold the horizontal portion of the rock-frame and to keep parts as shown in Fig. 4. The connection of the springs L L with the posts E E is made adjustable, as shown in Fig. 8.

M M represent cross-plates extending crosswise in the device, above the keys C C, die., and held in the posts lil E.

N N`l N3 N Ni NG represent a set of L-shaped levers, journaled at a fn, in the plates M M', and at one end, a', bearing upon the keys C' C2, &c., respectively, and at the other end, ai, con nected with the slides D D2, &c., respectively. Springs N1l N, Sac., supported upon bearings m m between the plates M M and pressing against the ends n ofthe levers NNi, die., act to turn the levers N N, e., on their bearings u n whenever the forward ends of the keys C G2, dre., are depressed and when the levers N N, the., are thus turned the slides D D?, Src., are moved endwise (to the right as seen) upon their bearings, and, when the keys C C", Src., rise again the slides are moved endwise to the lei`t,or back again to their original positionwthatis, each of the keys C' Cl C C C C is, through the levers 1 N N3 N4 N3 N, respectively, connected with the slides D D2 D:j

D1 D D in such manner that when any one of the keys is moved upon the fulerumc the particular slide with which the key moved is connected is moved endwise upon the posts lil E, the depression ofthe key allowing the slide to be moved in one dircctionnalnely, to the right-and the spring c at the rear end of the key being of su fficent strength to overcome the spring Nu and cause the slide to be moved in the opposite direction.

The keys C C, rte., are preferably provided with adjustable plates c c?, to make the Contact ofthe keys with the levers N N2, dac., exact and uniform, and the ends a2 a? of the levers are connected with the slides D D D Dl Di D" preferably as shown in Figs. 4, 5, (i, the slides in the edges toward the levers being notched at d and also at d, and the ends n engaging in the notches cZ-that is, each slide has a single narrow notch d to receive its particular lever end n, and, in addition to the I OO TIO

narrow notch, has other and wider notches, d2 d`, the object of which wider notches is as follows: It is desirable to have the lever ends n2 at their' extremities wider than the thickness of the slides they are respectively moving; but when thus made each end a2 would interfere with the other slides were it not for the wide notches d in theotherslides. The notches dz, however, and which are suitable arranged and of suitable width therefor, provide room foreach lever end 11jl to move its respective slide without striking or interfering` with the movement of any other slide.

IThe slides in the edges opposed to the tumbler-rods are notched, as seen more distinctly in Figs. 16 to 23. The object of these last-named notches is as follows: For each of the levers B )2, &c., there is a corresponding tumbler-rod, J J', 85e., and the desired movement of the levers B B2, che., is effected by previously moving the tumbler-rods JJ, &c. The movement of the tumbler-rods is accomplished by means of the notches referred to in the upper edges of the slides, the notches pro viding spaces into which the tumbler-rods can drop. It only remains to control the dropping of the tumbler-rods, so that they shall be dropped in the proper order, as desired. This is determined by the location of the notches in the upper edges of the slides D D" D3 D" DU.

The distribution of the notches along the several slides is made upon the following prineiple: In order to allow any tumbler-rod to fall, six notches, (there being six slides in the present case,) one in each slide, must be in line beneath the rod. As many keys as are depressed to allow that rod to fall, so many notches must, before the depression of the keys, have stood, not beneath the rod, but a little to the left thereof, ready to be brought to their place beneath the rod when the keys shall be depressed and the slides moved by them to the right; but as many keys as are not depressed for the production of the movement of the tumbler-rod, so many notches are already standing under the tumbler-rod, waiting to have those others just named brought into line with them. For example, the letter A (the present invention being here illustrated as an attachment to a typewriter) is com manded in this device by the depression of the single key marked A in Fig. 1 of the drawings. Accordingly beneath the A tumbler-rod (meaning the tumbler-rod which is connected with and effects the movement of that one of the levers B B2, &c., marking the letter A in the type writer) all the five slides that respond to the other keys CL C3 C C5 C must have their notches standing ready While the notch of the slide of that one A key stands out ofline to the left. Fig. 1G of the drawings shows the slides in plan view, the place of each tumbler-rod beingindieated by a cross-line, and the slides are shown as they stand when no key is depressed. In this figure the fifth line of notches, coming from the left, belongs to the letter A,as above described. Next,on the right, come the notches of the numeral 8, whoselever comes in that order in the Remington typewriter, to which this form of device is adapted. The numeral 3 is commanded in my system, to be hereinafter explained, by the three keys at the left of the key-board. Accordingly the three slides which respond to these keys (these are the three lower slides, as shown in Figs. 16, 17) are seen to have their notches to the left of the line of the tumbler-rod. Next come the notches of the letter Z, which letter is commanded by the two keys marked in Fig. l Iand U. The notches of the corresponding slides (designated by the letters IandU at the left of the slides in Fig. 17) accordingly are seen to stand at the left of the Z rod. The remainder of Figs. 16, 17 shows in the different combiuations the two classes of notches thatl have now been described-namely, those which stand in the line of the tu mbler-rod, ready to receive it, and those which must be moved up into line by the depression of the keys C C2 C C" C5 Cl'. The endwise movement ofthe slides is in the present case about one-sixteenth of an inch. That, therefore, is the distance to the left at which the out-ofline notches must stand in order that the depression of the proper keys` may bring them into line.

It will be seen, that since each notch", which, so long as its key is untouched, stands in line under la given tumbler-rod, itself moves to the right, when its key is touched, that movement breaks up the line of notches for that tumblerrod, and prevents it from falling. For example, the letter B in this device is commanded by the key marked A, in connection with the next key to the right of it. An examination of the A row of notches in Figs. 16,17 will show that, although the combination of keys used in producing B will bring the one A notch up into place for producing A, that combination will at the same time draw the notch on the next slide to the right and out of place, so that while the B tumbler-rod can fall the A rod cannot. In this way throughout the system the combination that produces any one line of notches under its proper tumblenrod breaks up every other.

The system of combinations used in this device is found very convenient; but I do not limit myself to it. It is shown in full in Figs. 16, 17. Its main features are as follows: The key marked C', Fig. 1, is not used at all for the production of letters, but comes into combination for producing punctuation -marks and numerals. The remaining ve keys produce the letters, as follows: rlhe keys marked A E I O U produce each by itself the vowels with which they are marked-that is, the key marked A produces A, thekey marked Eproduces E, and so on. For the production of the consonants,keys are combined according to the following plan: Any vowel-key that is simultaneously depressed with the key next to the right of it will. produce the consonant which in the alphabet stands next after that vowel,

the A key with the next producing the letter- B, the E key with the next producing F, the I key with the next producing J, and so on.

In making addition to the U key, since there is none beyond it, the live lettered keys are used in a circle-that is, the operator adds to the U key the A key,going round from the top of the key-board to the bottom. Thus theU key with the A key produces V. By extension of this system any vowel key in combination with the two keys next above it produces the second letter after that vowel. So A with two additional keys produces C, E with two additional keys G, and so on. A with three additional keys produces D, E with three additional keys produces Hgand so on. This systeimby using the keys in a circle, provides for nearly the whole alphabet, as appears from Figs. lo', 17. Those figures will also show what departures from this system have been made from necessity or for convenience of lingering. The combinations used for punctuation will appear from the same figures. The numerals are produced as follows: Number l is the sameas the letter I. Number 2 is produced by combining the two keys at the extreme left of the keyboard, number 3 by three keys, and so on up to Aft-er this 'the first key on the left combined with the third-that is, skipping the A keyproduces'. These saine with another key on the right produce 7, and on to i). The letter O is the cipher.

As above stated, the various tumbler rods J J', 85e., are respectively connected with the various levers B' B2, &c., and the dropping` of the tumblerrods is a condition precedent to the movement of the levers. The particular mode of operating the slides D D, the., in order that the tumbler-rods shall drop, and the means for connecting the tumbler-rods with and for operating the levers B B2, &c., are as follows: As a key-say the key Gilis depressed, as in Fig. G, the lever N at once acts to shift the corresponding slide,l`), endwise to the right, as described. The tumbler-rod J as yet has not dropped, as it cannot drop until the oscillating frame l has turned downward on its hinges t' By continuing to depress tlie lever C, however, it encounters the 1ockfraniel(tlie forward edge of which stands a little below the lower surface ofthe keys) and bears the forward end of the rockframe downward,as seen in Fig. i5. This downward move ment of the rock-frame brings the rub-plates 7u lc4 against the rollers 'im/m and causes the oscillating frameto be turned downward, as desired, upon its hinges. The set of tumblerrods moves with the frame l; but that tuinbler-rod J that is over the coincident notches drops thereimas seen in Fig. 5. The pendant 7' upon the end of the rod has dropped with the rod and suiiciently to bring its lower end in front of the vertical extension 75 ol" the rockframe. The pendant andthe extension are so relatively adjusted as to provide for the descent of the pendant before the upper end of the extension moves forward to encounter the i)eiula1it,for by rocking therock-frameforward, as described, by means of the key C the eX- tension ki is caused to strike and bear against the lower end ofthe pendantj. The pendant works up and down without friction in a perforation in thc lever B. rEhe levers B B2, &c., as seen in Figs. 4, 5, l5, are attached to the cross-bar F by means of the straps f, which in turn hang somewhat loosely upon pins on the bar F. This allows the rear ends of the levers B B2, &c., by the application of a slight force, to be sprung downward, as in Fig. 5, and when the force is removed the typewriter (or other) levers with which the levers B B2, ttc., are connected act to draw the rear ends ofthe levers B B, Snc., up again into their original positions, as in Fig. 4. Now, when the frame K is rocked forward, as described, thelower end of the pendantj is swung forward and the lever B thereby inclined, as shown in Fig. 5, and the desired movement of the lever B thereby obtained. On releasing the key C" it, by reason ol' the action of the spring c', rises, the rock frame, being actuated by the springs L L', rocks backward, the oscillating frame, by reason of. the counterbalances i i, is turned upward upon its hinges, the tumbler-rod is lifted out of the slides, the lever B is allowed to spring upward, and the slide D is caused to slide back again into its original position, when the operation can be repeated.

To facilitate the working of the device, an electrical attachment may be annexed to the device.

t represents an electro magnet suitably su pported in the device, and so as, when the electrical connection is established, to act upon an armature, r, which is attached to the rockfraine K', and thereby draw the part of the rock-frame with which the armature is immediately connected toward the magnet. The operation of this feature of the device is as fol l o ws BL represents a frame arranged beneath the keyboard and turning upon the bearings lr'. When any key is depressed, it encounters the frame R2 at its rear end and bears it down. A hook, r2, Figs. l, 3, which is suspended from the frame R, drops with the frame. The hook upholds a rod, r, that is in the circuit of the magnet, and when the hook drops the rear end of the rod r also falls, and so as to come in contact with the pin 1*, which is also in the circuit ofthe magnet. The circuit now being completed, the magnet acts upon the rockframe and supplements the force applied to the key. As soon as the key is released and rises a spring, yr", acts to lift the rear end oll the frame R2, whereupon the circuitof the magnet is broken and the rock-frame is free to be rocked backward. l

O represents the spacer. Itis pvoted at o. It is operated simply by throwing the hand upward from the key-board and lifting the l'orward end ofthe spacer. f

In Fig. l the rods P are shown to illustrate the connection of the levers B- B`, rte., with the mechanism of a typewriter, the rods extending from the levers B' B2, Sie., upward, suitably to form the connections with those levers of the type-writer which move the types. The type-writing mechanism is not here shown. Its construction is well understood, and it can be used with the present device by simply hooking the upright rods P over those levers of the type-writer which terminate in the several keys of that instrument and in the spacer. When the device is employed to operate the levers of other mechanisms, the connections leading from the levers B B", &c., are suitably moditied to snit the special mechanism in question.

In thus employing but few levers to operate many all the various parts of the mechanism above described are of value; but the principal feature of the device I consider to be the combination of the slides and tumbler-rods, for, while the other features of the device can be more or less varied, these two features must be retained. The slides and tumblerrods as a combination, however, can be modied in this: the notches can be made in the tumbler-rods and the place of the slides can be taken by straight edges of thin metal, which are made by their respective keys'to move or tilt forward to suit the notches of the tumblerrods, as shown in Figs. 24, 25.

I am aware that heretofore in type-writing devices there has been used the combination of movable plates having pcrforations, so that each change in position shall present a difierent opening through the entire series of plates, and I make no claim thereto.
