JUSTIFYING DEVICE FOR COMPOSING -MACHINES.

SPECIFICATION forming part of Letters Patent No. 753,336, dated March 1, 1904. v

' Application filed August 24, 1897.

.To all whom) it may concern.-

Be it known that I, JAMES A. WATSON, a citizen of theUnited States, residing at Washington, in the District of Columbia, have invented certain new in J ustifying Devices. for Composing Machines, of which the following is a specification. I

The present invention relates to justifying mechanism for matrix-making and other composing-machines. As illustrated in the drawings, it is applied to matrix-making machines; but it will be understood that certain features of the invention are applicable to other composing-machines, such as those which 'cast or set type.

The object is to justify lines of composition by automatically and uniformly increasing or decreasing the normal word-spaces of the lines the amount necessary to bring the lines to the standard length or'column width.

The invention will be described in detail in connection with the accompanying drawings, in which Figure 1 is a plan view ofjustifying mechanism embodying my invention. Fig. 2 is asection on the line 2 2, Fig. 1. Fig. 3 is a plan view illustrating a modification; and Fig. 4 is a section on the line 4 4, Fig. 3.

The justifier requires to be set either manually or automatically prior to the final production of each line. As illustrated, it is adapted to be set by keys and key-levers. It

is to be presumed that before setting the justi-' fier for any given line the number of wordspaces in that line and aggregate width of the word-spaces necessary to justify have been calculated or, what is practically the same n total variation space or amount to be added to or subtracted from normal spaces has been calculated. "In the case illustrated in the drawings I apply the justifier to a supplemental feeding device, which produces a movement additional or supplemental to that of the main feeding device.

In Figs. 1 and 2 A indicates a matrix-car-- riage which is connected by a rack 1 and pinion 2 with a ratchet-wheel 3, which is urged and useful Improvements v consists of a right-and-left that the'number of word-spaces and the Serial'No. 649,360. (No model.)

erated by a magnet 6. Any suitable feeding;

device may be substituted for that illustrated, such device being mounted upon the slide 7. The parts 1 to 6, inclusive, and their equivalents I shall designate as the .main feeding device B. The slide 7 is moved by a supple.- mental feeding device C, which, as shown, screw 8, one end of which operates on the threaded bearing 9 on the slide 7 and the other end operates in a fixed bearing 10 upon the main frame. The screw is driven bypinion 11 and gear 12,. friction-wheel 13, the friction-wheel 13 being connected to gear 12. The pawl is carried on an arm 15, which is connected by a link 16 to the justifyinglevers, to be presently described. The pawl 14 engages the disk 13 frictionally. so that the slightest movement of the pawl will be communicated to the disk and through it to the slide 7 and matrix-carriage A. r

The justifier proper consists, as shown ,in

and cooperating-pawl '14,

Figs. 1 and 2, of a dividing-lever D, a multiplying-lever M, two adapted to be applied to said levers, r espectively, and two series of keys d mfor operating said fulcra, respectively. The dividinglever D is pivoted to a connecting-rod 17, which slides in a guide 18. The opposite end of the lever is normally drawn back by a spring 19 against an adjustable stop 20, and it is provided with an armature 21 adjacent to a magnet 22, by means of which it may be drawn forward agalnst a stop 23. The stops 20 and 23 may be adjusted so that the movement of the dividing-lever at the stops will be equal to the movement required to be given the connecting-rod 16 in order to produce a unit movement of the matrix-carriage A.

The lever M and slide 17 are drawn to the right by a spring 24 against a stop 25, andthe other end of lever M is drawn to the left by a spring '26 against an adjustable stop 27. The fulcra d are arranged along the lever D at'regular fractions of its effective length, which isthe distance between thestop 20 and pivot 28, the first fulcrum being one-half of series of fulcra d m,

The movement permitted between the stops 20 23 fulcra m are similarly arranged along the leis divided by the number of. spaces in the line, ver M, being placed at fractions. of its eifectand if this amount be the total variation space ive length, which is the distance between pivot then the proper fractional movement will be 7 29 and pivot 30.
