The lifting of cylinder l releases it from stop 4 and at the same time engages a pinion 2l on the cylinder with the teeth of a rack 22, which rack may move in a slideway in the frame, as will be described. The pinion 21 always comes into engagement with the rack 22 at the same place when the cylinder is lifted. When the cylinder is dropped by the rocking of shaft 16 back to normal position, the cylinder goes on and completes a revolution, thus bringing stop 3 again into Contact with stop 4, and the parts normally rest in this position.

The keyboard mechanism is best shown in Figs. 3 and 4 and will now be explained. Three keyboards, with banks of keys, are shown, but more or less might be used. The cylinder is divided circumferentially into as many spaces as there are keys on all the keyboards. In the example illustrated seventyeight spaces should surround the cylinder, each space having mechanism for the attachment of cards C. The cylinder should be long enough to contain about twenty six cards when an alphabetical index is employed. In an arrangement by numbers or other basic foundation to the index of course the arrangement would correspondingly differ.

The rack 22 slides in a way 23 in the frame or a slideway thereon. The rack is drawn up in the slideway when released from the pinion 2l by a weight 24, attached to a cord 25,

which cord is also attached to the rack and runs over pulley 26. The power which drives cylinder l is suiiicient to overcome weight 24 and lift the same when the cylinder engages the rackbar 22; but when disengaged the weight draws up the rack-bar and the movable keyboards.

The rack 22 is attached to a bar 30, which bar has a bracket 33, with its edges extending under the edges of the guides or pieces which form the slideway 23. Rolls or other antifriction devices 28 may be used to render the movement easy in the slideway. The shelf 34, which is rigid with rack-bar 22, extends under the keyboard 42`of the third alphabet.

Keyboard 42 has a bracket 43, extending into a guideway 42in the frame parallel with the guideway 23, and this keyboard 42 has a shelf 44 exactly corresponding to the shelf 34 of the rack-bar and extending under the next adjacent keyboard.

The two inner keyboards 42 and 52 are duplicates, and board 52 moves in slideway 53, but to a less distance than does the keyboard 42-that is, the rack-bar may slide in its way the length of the three keyboards, the keyboard next the rack may slide the length of two keyboards, the middle keyboard may slide its own length, and the outer keyboard v 62 is fixed. A downward projection 91 from each succeeding keyboard is engaged by the shelf of the keyboard next toward the rackbar. The movable keyboards are moved upward by the engagement of the shelf with this projection, and the projection on the fixed keyboard serves as a stop to prevent the other keyboards from moving too far under the influence of the weight.

The mechanism to ease friction in the sliding movement of 'the keyboards may be the same in each in stance or any usual antifriction mechanism. For convenience in construction the bars D, which constitute the covers of the slideways, are made removable and held in place by screws 36.

The outer keyboard 62 is firmly secured to the frame at the side of the slideways by any suitable holding means. For convenience of adjustment the outer keyboard should, however, be removable.

In Fig. 3 the keys and rock-shafts are shown on the keyboard on a small scale. In Fig. 4 only the left-hand keyboard is shown with rock-shafts and springs, parts being omitted from the other keyboards for convenience of illustration. Each key is a plunger, arranged so that its lower end may pass entirely through a hole in the keyboard and project below said board. The keys are normally held up by springs 65, resting on key-guides 66, attached to the keyboard. Each key has a pin 67 projecting at one side thereof and in position to engage a lever 68 on the rock-shaft 69 whenever the key is depressed.

Rock-shafts 69 are held in suitable bearings and extend alongside a range of keys. A lever 70 on the rock-shaft engages with a slide 71 near the end of the keyboard. Slide 7 1 is supported in suitable guideways and engages with a gate 72, which gate is pivoted to a bracket 73 on the keyboard. Normally each gate 72 projects below the end of its keyboard, as in Fig. 4. Thus gate 7 2 on the fixed keyboard 62 projects below said board, as shown in Fig. 4, and prevents keyboard 52 from moving down in its slideway; but when any key on board 62 is depressed ythe act of depressing it rocks one of the shafts 69 and swings the gate 7 2, so that its lower end moves away from the front of shelf 54 and let's the keyboard 52 slide down in its guideway. The force of the cylinder, rack, and keyboard connections impel this movement, as explained, and overcome the resistance of weight 24. The key, which thus serves to release the gate holding the neighboring keyboard, itself projects below its own keyboard and becomes a stop for its neighboring keyboard. Fig. 6 shows in detail how the bracket on a keyboard may engage a notch in the key of a neighboring keyboard and hold the key depressed after it is once depressed until it is released by the depression of cylinder l to set all the mechanism back to starting position.

In the illustration I have endeavored to simplify constructions, and I have not expected to show working` dimensions of parts, but only to indicate the general principles of constructions. Mechanical skill can make many changes` without departing' from the general principles above outlined.

I do not here attempt to describe mechanism for holding the index-cards tothe face of the cylinder. Such means are common in this art.

By preference I attach a hand-rest SO to the frame in front of the cylinder and cover the rear part of the cylinder with a shield oreasing 81. The face of the cylinder is arranged to support the index-cards in well-known manner, and the entries may be made on the cards either before or after their attachment tothe cylinder and on either or both sides thereof. The position of the cards on the cylinder causes them to hang suspended from the lower side of the cylinder and to incline either rearward or forward on the upper side of the cylinder, the line where the cards drop over being the line for inspection, as is usual.

The operation of the machine is as follows: Assuming that the operator desires to inspect a particular name properly arranged among the cards on the cylinderwfor instance, the name y"Hellerf He first lifts the cylinder to starting position by means of lever 18 and connections. Then the operator will depress the key H in the fixed keyboard. Immediately the gate at the end of the keyboard 62 is lifted, and the cylinder l begins to rotate, drawing the rack-bar 22, and by this means drawing down both 'of the inner keyboards until keyboard 52 is stopped by its bracket 54 engaging the depressed key H, when the mechanism comes to a stop. The operator then depresses a key E on the keyboard 52. This releases the gate holding the keyboard 4Q and permits this keyboard to move down until it is stopped by the key, when the machine comes to rest. The operator then depresses the key L in board 42, and the sliding rack is in likle manner released, and the machine moves to its final position, which brings the cards in the peripheral space which contains all names beginning with the letters "H EL to position for inspection at the front of the machine. The fourth letter in the name being L7 he now directs his attention to cards bunched under that letter in the alphabet running lengthwise of the cylinder where all names having' the first four letters H E LL should be found. Then the inspection has been made, the hand-lever 18 is rocked back, lowering cylinder 1 and releasing' it from rack QQ. The

Simultaneously the weight Q4 draws back the bar 22 and the keyboards connected thereto, the depressed keys are lifted by their syjirings, and the gates which hold the keyboards from sliding' down their guideways fall to their holding position.

Suitable buffers may be provided to take up the jar of stopping', such as are common in the general mechanism of the character described. The same is true of the stops to limit the movement of keyboards in the slideway.

The general principle on which the machine with three keyboards operates may be stated as follows: I take a certain space and divide it into twenty-six equal spaces, the number corresponding' tothe number of letters in the alphabet. Beginning' at one end I take the alphabet and designate the first space by "-A, the second by 1), following with the balance of the letters in the regular order they occupy in the alphabet. Thus h designates the eighth, e the fifth, and l the twelfth space, Sac., starting from the front or a space. Now by triplicating this arrangement and letting' a of the second rest against z vor last space of the first and a of the third rest against Z of the second we have seventyeight spaces from the first, inclusive, covered by three alphabets. Now by depressing' key "h I bring the first space or afinthe second alphabet to the eighth space from the beginning of the first alphabet. By depressing e of the second alphabet I bring a of the third alphabet to the fifth space of the second or the thirteenth of the first. Depressing next the l key in the third alphabet, I bring the rack to the twelfth space of the third alphabet or to the twenty-fifth (S-l- .5d-12:25) space from the first space of the combined alphabets. This has moved the cylinder around to within twenty-five of its peripheral spaces from its starting-point or a distance of' fifty-two ofI its peripheral spaces. By a similar operation the keys H A L would move it to the twenty-first space from its starting-point,(S-l-l-l-IQ: 1.) Now the only difference between H A L and H E L is the middle letters A7 and IQ and their relative positions to LA or first letter of the alphabet produce the difference in the results twenty-five and twenty-one. Thus a combination of spaces marked by the letters of the three alphabets and manipulated by keys standing' at the entrance of each one of the spaces serves to distribute the names among' the seventy-eight alphabets running lengthwise of the cylinder. In other words, each circumferential space on the cylinder does not correspond to a letter in the alphabet, but to a combination of three letters of the alphabet, and yet there are seventy-eight spaces, because there are seventy-eight possible combinations.
