TYPE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No.. 248,047, dated October 11, 1881.

Application filed May 28, 1881. (Model.)

To all whom it may concern Be it known that I, WILLIAM A. LORENZ, of the city of Brooklyn, State of New York, have invented a new and useful Improvement in Type-Setting Machines, of which the following is a full,'true, and exact description, reference being had to the accompanying draw- 1n gs.

It has been found to he a matter ot' the utmost importance, in the practical Working of type setting and distributing machines, to di-' minish asmuch as possible the losses of time which occur in the necessary transferring of the typefcases from the distributing-machine back to the setter, and vice versa.

One of the objects of my invention is to enable a full case to be substituted for one which has beenemptied in the shortest possible time and with the least possible exertion.

Heretofore, in substituting a full case forl one which has been emptied, it has been necessary to raise such case above the frame in whichitrests, and to drop ittherein from above. This has been found to be a diflicult operation, owing to the great Weight of the full cases, and there has been a liability to pi77 the type by carelessly removing the case from the supporting-frame. I avoid these difficulties by pivoting the cradle in which the type-case rests, so that it can be rocked down within reach of the operator, and subsequently raised to its position of operation in the machine.

' My improvement has a special relation to that class of type-setting machines in which the type are held in combined cases, and is shown as applied to one invented by C. W. Dickinson and myself.

It is very desirable in this class ot' machines that the cases should be easily removedwith- Vout disturbing the relations of the type, for the reason previously mentioned, and it is also desirable that these cases should be as large as possible,`in order to supply the setter with the fewest possible changes of the cases.

In makin gthe cases large they become heavy and less easily managed.

Part of my improvement is intended to aid the operator in handling Vheavy cases, and in,

leaving undisturbed the relations of. the type 5o in the cases when removed.

my back plate 5 Fig. 3, the plan of the same; 55

Figs. 4, 5, and 6, views'of my adjustable race.

The frame or cradle A, Fig. l, is pivoted on the shaft B, fixed to the cradle-stand P, on which it can be rocked by the handle A2, pivoted at A3 into a vertical position resting on 6o the bearing A,.or` into a horizontal position resting on the bearing O. Fast to this cradle are the glass'plate K, the guidefbar E, the

roller F, and the rest-bar W. A machine typecase, C, is shown in the cradle A in its vertical position standing upon the support-bar J,

behind the glass K, against which it is held by the wedge-roller L. When the-case is in place the lowest letter in each channel of the case, as at T, is in front of its plunger D, which 7o the depression of the keyD' will, through X X X, force against that letter, pushing it forward until it rests against Vthe roller F, when gravity, acting upon its free foot, dropsit into its channel in the back plate, Gr, down which it slides to the race I. When the case A is rocked backward into the horizontal position shown in the dotted lines any letter that may have been accidentally leftin the guide-'bar falls back into the case, the roller L drops from M to 8o M, and the case is easily withdrawn from the cra"- `dle, sliding on the shelves Q and the rollervat M. The end of the -full case is then lifted upon the shelt' Q and the case slid into its place,

the cradle is rocked upward, the roller L falls 8 5 forward behind the case, holding it firmly against the glass K, and the operation of typesetting can again proceed.

Attached tothe bottom of the cradle A are two springs, S and S', which have hold ofthe 9o short lever R, attached to the bottom ot said frame, and bear against arms R and R2. The object of these counterbalance-springs, which are made ofthe desired tension, is to allow the rocking of the cradle into its upright or depressed position without unnecessary jar or shock. This rocking can be readily accomplished by means of the handle A2, pivoted at A3, the point of which enters a' socket at f.

In order ro-operate the cradle the handle roo X3, which, when moved downward, actuates another lever, Y, which strikes against the line of bell-cranks X, and withdraws any of the plungers D which may have been accidentally detained in the type-cases. By holding this lever X down from the stop X3 by means ot' the screw X, the keys D are locked and the machine cannot be operated. The use of this safety-lever and cradle obviates the danger of injury to the machine from the detention ot' plungers in the case to be removed, and the danger of throwing into pi any column of type whose lowest letter may project into the guide-bar when its case is removed.

H represents my improved gate, which is readily removed from the machine without altering ils adjustment or disturbing any ot the other parts.Y

a a represent the pendulum with the gate attached; I), the pivots; c, the stand; d, the adjustable stand; c, the adjusting-spring ofthe pressure-screw, and g the stop-screw.

By arranging the adjusting parts away from the throat ot' the back plate, G, they are not aiiected by dust and dirt, as before, and therei'ore preservctheirdelicacyintact. This pendulum a a can he removed with its pivot b from the support-stand d, cleaned, and returned without interference with its other parts.

Figs. 2 and 3, Sheet 2, represent improvements in the back plate, G, of the machine. It is desirable that each type, ot' whatever weight, should occupy, as nearly as possible, the same time in passing` from the case through the back plate to the race. To accomplish this I make the back plate of different heights, as shown in Fig. 2. The center division, of grooves is made longer or higher than the wing-divisions y and z. I make the center channels, k and lr, ot' a little longer than the inner channels, m m, of the wings, and the outer channels, 0 o, ofsv longer than the outer ones, p l), of y and z. .Type ot' equal weight will pass through these two sets of channels p and o in approximately equal times, as the channels near the center impart less friction to the moving type, but being longer give to this faster-moving type a greater distance to traverse.

Fig. 3 represents a top view of this back plate, G, showing the grooves to increase in depth (for the heavier type) in the x division from the center outward, while in the wingdivisions they increase in depth outward from the mdivisiou. This construction of the back plate and its grooves equalizes the time occupied by the type in falling, and permits the key-board to be more satisfactorily arranged.

In Fi". 2 is likewise shown an attachment for the insertion into the line which is passing from the setter of quadrats or longer distillguishing type or spaces for the purpose of indicating to the justifying-operator, who justities the type as they pass from the machine, that a paragraph should be made at that point. The distinguishing type or space usually employed is of a greater length than the type which are being set in the apparatus, whereby the eye of the justifier is readily directed. A series of these quadrats or long spaces rest in the channel u, (shown on the let't side of the back plate,) the lowest one resting against the corner or shoulder c, each quadrat resting against and supported by the one below it in the line. The last quadrat, having its foot resting against the shoulder c, has its upper end against the shoulder or guide on the opposite side of the channel. If the finger of the operator be pressed into the hollow w', which exposes the quadrat to the action of the finger, it is obvious that the lower end of the quadrat will be raised free of the shoulder fu, since the upper end of the shoulder q acts as a i'ulcrum or bearing-point, and the type will then slide down the channel u into the race.

Figs. 4, 5, and 6 represent improvements in the race whereby the same is made adjustable, while means are provided for sustaining the type as they pass down such race.

i represents the stationary side of the race; l, the movable side. The side t is provided with the openings s s, to allow the escape of any dirt which may pass out with the type, or which might serve to impede its progress iu the race. The fixed side t' and the bottom a of the race are one piece. The side lis made adjustable on the pivot r by means ot' the eccentric pivot h, having the milled handle h. By turning this handle on the eccentric pivot the adjustable side pivoted at r can be thrown into the position shown in Fig. 6, where the channel is closed. Attached to the adjustable side l are the pressure-springs t and t', which serve to maintain the type upright in the channel.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a type-setting machine, the combination of a pivoted type-casc-supporting frame with a wedge-roller, which serves the double purpose ot' locking the ease within the frame when the frame is elevated, and also serves as a roller for the support and withdrawal ofthe case, substantially as described.

2. In a type-setting machine, the combination of a series of reciprocating plungers with a hand-moved safety-lever, by means of which the plunger can be certainly withdrawn from the type-cases, substantially as described.

3. In a type-setting machine, the combination of operatin g-keys and a locking apparatus, substantially as described, whereby the operation of the machine can be prevented, excepting when the keys are unlocked by the operator.
