Application filed December 8, 1908.

Now the present invention has for its To all whom it may concern: 1 Be it known that I, FRANK HINMAN j principal object to provide means whereby PIERPONT, a citizen of the United States, this spacing out of the characters may be temporarily residing at Horley, county of i automatically effected during the formation Surrey, England, have invented a certain j of said characters and without loss of time new and useful Improvement in Letterl or interference with the normal action of Spacing Mechanism for Type Casting and the mechanism for dimensioning the type Composing Machines; and I do hereby debodies to accord with the characters borne clare the following to be a full, clear, and thereby or the justification of the lines, to exact description of the same, reference bewhich end it consists, broadly, in equipping ing had to the accompanying drawings, the type casting and composing machine forming a part of this specification, and to with auxiliary or supplemental mold adjustthe figures of reference marked thereon. ing devices adapted to efiect an abnormal The present invention relates to the class variation or enlargement of the mold cavity of type machines in which the mold is proat the time each of said spaced type is provided with adjusting devices for varying duced, so that the bodies of the designated the dimensions of the mold cavity to corretype will be varied or increased, setwise, by spend with that of the character or space a predetermined amount corresponding with to be produced, and it is particularly adaptthe desired spacing. ed to pattern controlled type casting and As applied to pattern controlled autocomposing machines provided with a pluralmatic type casting and composing machines ity of matrices and means for selectively the invention also includes the addition of presenting the latter to the mold, for the signal interpretating devices responsive to production of justified lines of single type the pattern and operating to automatically which are afterward assembled in column couple and uncouple the auxiliary or suppleform. mental mold adjusting devices with the nor- 8 It is often necessary or desirable to space ma]. mold adjusting devices.

Heretofore it has been upon said interpretating devices, and when customary to effect this spacing or opening the pattern employed is produced, as usual, out of the characters by the insertion of upon a keyboard composing machine, means thin quads or spaces, and as the spacing reare provided for registering the additions quired is less than the thinnest space type made to the spaced type, to the end that due that automatic type casting and composing allowance may be made therefor in figuring machines are ordinarily capable of producout or computing the justification fraction ing, the insertion of such spaces is usually for the line.

mold '1; mold-blade 2; abutment slide 3;

normal wedge 4.;

justification wedges 5, 6; transfer blocks or 1 wedges 1, 8, locking 10d 9; adjustable limiting abutment 10; pattern or record strip 11; tracker bar or board 12; and pressure conduits 13 communicating with the stop pins of the primary gaging devices, the devices for coupling each justification wedge with its positioning mechanism, and the devices for reciprocating rod 9 to bring transfer wedges 7, S alternately into action and therebytransfer control of the mold-blade from the normal wedge alone to the normal vice versa.

In the patented machine the justifying spacesignal contains a perforation 14 not employed in connection with any of the character signals, and which operates to effect the lifting of rod 9Ifrom engagement with the actuating rod of transfer wedge 7, to that of transfer wedge 8. The transfer wedges are both normally retracted-with respect toabutment 10, and, in the absence of said perforation 14, rod- 9 operates to retain '7 in retracted position and permits transfer block Sto be advanced into contact with abutment 10 so that the normal wedge in conjunction with said transfer wedge Sdetermines the position of adjustment of mold blade 2 and the dimensioning of the mold. This is the condition when character and other non-justifying type are produced. When, however, a justifying space signal is presented, its perforation 14 effects an upward movement of rod 9 while both transfer wedges are in their retracted position, thereby releasing transfer wedge 7 and engaging transfer wedge 8, so that the former will be advanced into contact with abutment 10, thereby causing the adjustment of the mold-bladeto be performed by the normal wedge acting in conjunction with the ustifying wedges and transfer wedge 7. Thus the character and other non-justifying type are dimensioned, set ways, through the adjustment of normal wedge and the justiplus justifying wedges and ify1ng type through the normal and justifyn g wedges.

To effect the s acm out of the characters swung in the opposite direction.

terrupter or arresting means such as a dis-,

tance block 20 adapted to be interposed between the transfer wedge 8 and abutment l0 whenever the body of a character type is to be enlarged. The usual spacing required is approximately two units, and the distance block 20 is of such dimensions that when interposed it will interrupt or arrest the transfer wedge at such point in its traverse toward abutment 10 as to permit a two unit lateral displacement of the normal wedge and slide'3 when the mold blade is retracted into contact with said slide thus increasing the set-wise dimensions of the mold cavity a corresponding amount over and above the predetermined size as determined by the longitudinal displacement of the .normal wedge and corresponding with the dimensions of the character to .be produced. The effect of such adjustment is to produce a type whose body is wider than normal by an amount equal or proportional to the thickness of distance block 20,.the excess being applied on one side only of the body inasmuch as the seating of the matrix remains the same for the spacing as for normal type.

Distance block 20 is detachably secured to the slide 21 guided to reciprocate on a frame 22, and engaged by one arm-of a bell crank lever 23 provided with a shoulder 2a. The opposite arm of lever 23 is pin-jointed or otherwise correspondingly connected with one arm of a bell-crank site arm whereof is furnished with a shoulder 26. Coupled with a rod 27 and supported to reciprocate across shoulders 2-1, 26, is a double pawl 28, the point 29 whereof ouone side the pivot is adapted to enter below and engage shoulder 26, when the pawl is swung in one direction, while the point 30 below the pivot is adapted to enter below and engage shoulder 24 when said pawl is A spring 31 coupled with pawl 28 tends to hold the latter with its point 29 in the path of shoulder 26, and a piston '32 working in a cylinder 33 in or .on frame 22 operates in opposition to said spring to withdraw point 29 and advance point 30 into the path of shoulder 24:.

Cylinder 33 communicates through a branch pipe with one of the ports in the tracker bar leading to a stop pin designatlever 25, the oppoing a quad matrix other than the justifying space matrix, but interchangeable therewith, and rod 27 is indirectly coupled with locking rod 9, as through lever 34L engaging between a shoulder 35 and spring 36 carried by rod 27, said lever 3% also extending between collars 37 carried by rod 49 so as to partake of the movements of the latter. Normally distance piece 20 is maintained in its lowest or retracted position, out of the path of the transfer wedges, where it in no wise interferes with the normal operations of the machine, and to bring said distance piece into action it is only required that pressure be admitted to cylinder 33 at the time pawl 28 rises.

As before indicated the usual justifying space type signals are each composed of a designating perforation let (operating through trip rod e9 to couple locking rod 9 with the center pin actuating lever) and a perforation 38 controlling a stop pin of the series operating to control the position of the normal wedge and of the die case in one of its two way movements. "referably the signal for spaced type is associated with this justifying space signal by the addition of a perforation 39, Fig. 5. The port in the tracker board controlled by this perforation 39 communicates with and admits pressure to the cylinder 33, consequently when the spaced type signal is presented perforation 1 operates to couple up the pawl carrying rod 27 with the center pin lever, while perforation 39 operates through piston to tilt pawl 28, thereby withdrawing its point 29 and projecting point 30 beneath shoulder 24. As the center pin lever rises, to shift locking rod J, pawl 28 is elevated, and, by the engagement of its point 30 with shoulder 2i, tilts levers 23, 25, and elevates distant block 20 into the path of transfer wedge 8, as illustrated in Fig. 1. After the justifying space indicated by the signal has been cast locking rod 9 and pawl 28 return to normal position, and, pressure in cylinder 33 having been interrupted by the presentation of the next succeeding type signal, pawl 28 is tilted by its spring to withdraw point 30 and present point 29 beneath shoulder 26 of hell crank lever 25. The distance block 20 retains its elevated or operative position until the presentation of a space signal in which perforation 39 has been omitted and each type cast in the interval will have added two units or other predetermined uniform degree of increase in width on one side of its body. The omission of perforation from the space signal is the signal for closing the spaced out matter and returning to normal, and when such signal is presented rod 9 and pawl 28 reciprocate as before, but this time as no pressure is admitted to cylinder 33 the pawl is not tilted and its point 29 engaging shoulder 24L tilts levers 23, 25, to withdraw dis tance block 20 from the path of transfer wedge 8.

As is well known the casting machine with which the improvements are shown associated is so organized that the types are produced in the reverse order from that in which they are composed on the pattern, consequently in setting up the pattern the extra-spacing signal 39 will be formed in conjunction with the justifying space signal immediately succeeding the spaced out matter, the normal justifying space signal preceding said matter serving to cut out the extra spacing mechanism; and should it be desired to extend the spaced out matter over one or more justification spaces the perforation 39 will be annexed to their signals but no change in the position of distance block 20 will be occasioned by the presentation of said signals as the admission of pressure to cylinder 33 will again withdraw the point 29 of pawl 28 from the path of shoulder 24: and levers 23, 25, will not be disturbed upon the ascent of the pawl. If desired the spaced type signal perforation 39 might be arranged to control a port in the tracker board communicating directly with cylinder 33; but one of the ports controlling one of the stop pins can be utilized providing the matrix designated thereby is a blank or quad. The fact that the port with which perforation 39 registers also controls a row of matrices and that certain of the typesignals contain perforations registering with said port, to designate the row, does not interfere with its use in connection with the spaced type actuating mechanism, inasmuch as said type signals do not contain the perforations 1%, hence while pawl 28 will be tilted it will not be reciprocated to engage levers 23, 25, or either of them.

Believing himself to be the first to pro- ,duce justified lines composed in part of self spacing individual type, formed in the order of composition, to equip automatic type casting and composing machines with supplemental mold adjusting devices adapted to produce said self spacing type, and to control the production of the latter through the medium of a pattern or record strip, applicant desires it to be understood that the invention as claimed herein is not limited or confined to the special and preferred form of embodiment herein described and illustrated but includes as well other and equivalent means of adjustment and control adapted and operating to produce like results.
