SPECIFICATION forming part of Letters Patent No. 468,973, dated February 16, 1892. Application filed September I6, 1890. Serial No. 365,176. (No model.)

To all whom it may concern.-

Beit known that I, CASPER L. REDFIELD, a citizen of the United States, residing at Chi# cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Matrix-Making Machines, of which the following is a specification.

My invention relates to machines operating to impress type-dies in succession into a maro trix material from which plates may be cast for printing; and the object is the production of a rapid and accurately working machine that employs a separate key for each type-die. This object 'is accomplished by means of the mechanism illustrated in the accompanying drawings, in which- Figure l is aside elevation of the machine; Fig. 2, 'a plan; Fig. 3, a central longitudinal section showing certain interior parts in ele- 2o vation. Fig. l is a horizontal section on the zigzag line a: x of Fig. 3. Fig. 5 is a transverse section through the typecarrying frame, some parts being omitted. Fig. 6 is an enlarged detail of the type-die and co-operating parts; Fig. 7, a detail of the diesocket attached to the die-carrier. Fig. 8 is a plan of thc feed-escapement. Fig. 9 is a central longitudinal section of the same; and Fig. 10, a sectional elevation, enlarged, show- 3o ing the spacing-keys and levers. Fig. 11 is a plan View of a portion of the lower drumhead, showing the lower guide-slots for the key-levers. Fig. l24 is a plan View of a portion of the upper drum-head, showing the upper guide-slots and the pivot for the upper A portion of the key-levers; and Fig. 13 is an enlarged view of the pivotal portion of one of the die-levers and connections.

The bed-plate of the machine consists of 4o an outer shell (designated 1) and an interiorremovable portion 2. To the bed-plate 1 is attached a frame-work 3, having panels et. In the interior part 2 is a longitudinal slot 5, in which is a rack 6, attached to the matrixcarriage 7, for moving it horizontally lunder the printing-point of the machine. At the extremes of the space in which the carriage travels are two pieces 8, which support a plate 9, that is provided -with a bushing 10, having 5o a countersunk gnide-hole 1l at the printingpoint for centering the dies.

On the plate 9, over the pieces 8, is mounted a ring 12, and supported on the latter is a drum-like shell 13, having in its lower head 14 radial slots l5, and in its upper head 1G 55 similar but shorter slots 17 in the same vertical planes as the slots 15. These slots are for admitting and guiding the die-carrying levers. On the upper head 16 is seated a circular frame 18, having a tubular central part 6o 19 extending downward through both heads of the drum 13 to form aguide for the piston 20, which carriesthe impressing-plunger 21, and on the top of the frame 1S is mounted another frame 22, having boxes 23 for ashaft 65 24:. The outer end of this shaft is supported in a box 25, mounted on the drum-head 16, and is driven by means of a combined pulley and Hy-wheel 26. The shaft carries an eccentric 27, which is connected to the piston 7o 2O by a connecting-rod 28 for reciprocatingiti When the machine is in use, the shaft 24 is constantly rotated, so as to keep the piston and plunger continuously reciprocating, and the die-levers are separately operated to carry 7 5 the dies successively to the center to receive the thrust of the plunger for making the matrix-impressions. l

The upper head 16 of the drum is recessed on top around its central opening to form a 8o shelf 29, having an inclined shoulder or backing 30, and on this shelf and in contact with the shoulder is a ring 3l, of round wire, on which are hung the type-carrying levers V32,

that depend through the slots l5 and 17. Thel 85 v upper ends of the levers 32 are b'ent outward at acute angles to form arms 33, and the angles between the arms andthe lev'erlbars are slotted, as shown at 34, to form bearing'fsfor the ring 31. By these means the levershang 9o loose and independent on the ring and can be separately lifted off without disturbing remaining levers on the ring. To prevent the possibility of the levers becoming displaced in operation, they are rounded at the bend, and the part of the frame 18 at which it turns into the downward extension 19 is curved, asshown at 35, so as to conform to the bend in the levers and present smooth bearings for the levers in case they are shifted slightlyinroo ward. The lower ends of the levers 32 are bent in the same planes, but in direction opposite the upper ends and at right angles to the straight portions to form arms 36, to which are riveted or otherwise connected the diecarrying sockets 37. In normal position the levers 32 have their lower ends resting against the ring 12, and they are held to this position by means of spiral springs 38. The springs may be given any desired tension by drawing their outer ends through holes 39 in the sides of the drum 13 and securing them .in their positions of adjustment by means of set-screws 40.

' The tubular piston-guide 19 has a collar 4l, that fits in a central opening Vin the lowerdrum head 14, andv immediately below this collar is a band of leather or other suitable material 42, serving as abuffer or cushion for receiving the strokes of the die-carrying levers when operated and forstopping them in proper position by contact of their shoulders 43 with the buffer.

Near the outer ends of the arms 33 are holes 44 and slots 45, in which are secured the lower ends of rods 46, that extend upward through holes 47 in the frame 18 and connect the die-carrying levers 32 with horizontal levers 48, that have their ends pivoted on a shaft 49, that is secured in the frame 3.

The free ends of the levers 44S are connected by wires750 to the free ends of anotherset of levers 5l, that are pivoted on a shaft 52 in the lower front portion of the machine. Each of these rlevers 51 is connected by a stem 53, which passes through thefront coverplate 54 -toan loperating-key 55, suitably marked Vto indicate the character it controls. Each lever-51 has an adjustable clip 56 attached to it and extending below and directly over one` of six transverse levers 57. The levers 57 :have their ends 58 bent at right angles and pivoted on a shaft 59, that is supported in brackets 60, attached to the side'panels 61 of the machine-case. The levers 57 -rest on the heads of pins 62, that are supported in a block 63 bysprings 64. f

On the shaft 59 at its center is a sleeve 65, to whichy are fastened two arms 66 and 67, the former extending horizontally under the levers 57 and in position to be engaged by them when they arev depressed, and the latter extending downward into a slot 68 in a horizontal bar 69. The bar 69 effects the operation ofa variable-feed escapement for the matrixcarriage, and the levers 57 and the pins 62 correspond in number to and determine the extent of the several feed movements. The clips 56 are attached to the respective levers 51 in position to engage the proper lever 57 for eecting the feed proportioned to the character operated by the particular lever 51. The levers 51 for all characters requiring like spacehavetheir clips arranged to co-operate with the same lever 57.

In the mechanism illustrated .provision is ished by the mere addition or omission of devices similar to those described. y

The bar 69 is capable of longitudinal reciprocation when actuated by the arm 67, and is guided in its reciprocations by posts 70, fitting in slots 71 in the bar, and is prevented from rising by nuts 71 on the posts. The middle portion of this bar is' somewhat elevated and spans a scape-wheel 72, that is fastened to the hub of a gear 7 3, which meshes in the rack 6. The bar 69 carries a free pawl 74 at one side of the scape-wheel, and to a pin 75 in the bar over the center of the scapewheel ispivoted a swinging lever 76, having retreating steps 77 on its edge and a holdingpawl 78 pivoted to its under surface diametrically opposite the pawl 74. -Thescape-wheel 72 has an initial tension in the direction of lthe arrow z, and when thejpawl 78 is in engagement with the teeth of the scape-wheel the lever 76 is carried around bv'the wheel until it is stopped by contact with an adjustable screw 79 on'a post 80.l g

On the bar 69 is a post 81, to which is attached a spring 82,with a tension to move the lever 76 in a direction opposite that in which it is moved when engagedbythe scape-wheel, so that when the pawl 78is free from the teeth of the scape-wheel the lever 76 will be moved away from the screw 79 until its movement is arrested by one of the series of stop-pins 62. The bar 69 carries another post 83-.on its top, against which a spring'84, that is secured to a post 85, bears and tends to move the bar toward the right, so as to cause disengagement of the pawl 74 and engagement of the pawl 78 with the scape-wheel. The portion of the bar 69 which is under the block 63 is slotted, as shown at 86, so as topermit thepins 62 to pass down through it into the path of movement of the lever 76, These pins 62 are arranged in a line radial to thescape-wheel, andas the steps 77 on the lever 76 are retreating steps the extent of the movement of thelever given IOO IIO

it by its spring 82 is determined by the particular stop-pin that has been depressed to 'engage one of the steps 7-7 and intercept the lever movement. `Vhen one of the characterselecting keys 55 is depressed, the appropriate lever 57 is likewise depressed, projecting the pin 62, which it engages, into the path of the stepped lever, and producing a partial rotais engaged by the corresponding step on the lever. This movement brings the pawl 78 in position to re-engage the wheel in rear of its former hold a distance of one, two,.or more teeth, determinable by the location ofthe particular stop-pin that has beenprojected, and

when the lever 57 is permitted to rise upon release of the operating-key the bar 69 is retracted to its initial position, causing the pawl 7 8 to enter and the pawl 74 to retreat from the scape-wheel teeth, and so permitting the wheel to revolve until the lever 76 is restrained by its stop 79. The measure of this escapement is governed by the number of teeth intervening between the Iirst and second engagements of the pawl 7 8.v

Near the front end of the' portion 2 of the bed-plate is a post 87, on which is a gear 88, that meshes with and moves the rack 6, and fastened to the gear 88 is a graduated disk S9, and above this disk and loose on the same post 87 is another gear 90, and a disk 91, in

which latter is iixed a post 92, to which is at-A tached the end of a coil-spring 93, the other end of which is fastened to the huh of the gear 88, which spring serves as the motor for the feed-escapement devices.

In mesh with the gear 90 is a -segmental gear 94, formed on one arm of a lever 95, which is pivoted on a post 96 in the bed 2. The outer arm 97 of the lever passes through a slot 98 in the panel 61 of the machine-case, and the lower edge of the slot has teeth 99, that are engaged by a lip 100 on the lower face of the lever-arm 97. The object of this construction is to permit a change at will of the tension of the spring 93, and consequently the force with which the carriage 7 is moved when released by the escapement. Thus, moving the lever-arm 97 toward the front of the machine will decrease the tension of the spring 93, while moving it in the opposite direction will increase the tension. The outer portion 1 of the bed-plate has a projection 101, the inside of which is cut away to let the graduated disk S9 clear the frame, when the plates 1 and 2 are separated by lifting on. the part 1. In this projecting portion 101 is a fixed pointer 102, covered by a glass plate 103. All the movements of the escapement affect the graduated disk 89, and may be read by means of the fixed pointer 102, so that at all times the sum of the feed movements may be ascertained to aid in the j ustitication of the line of impressions.

' and have the same connections as the levers 51, except that they are not connected by wires or otherwise to the upperlevers 4S, and consequently the depression of any one of them does not operate a type-lever. Tosupport the free ends of these levers 105 a spring 106 is provided for each lever. This spring may connect the lever with the machineframe, or it may be a spring placed around the stem 53A of the spacing-key, as desired.

Each of the spacing-levers is provided with a spring-pawl 107, co-operating with a ratchetwheel 108 on a transverse shaft 109, that carries a wheel 110, having graduations 111 on its rim'. A slot 112 in the cover-plate 54 enables the graduations tobe seen, and a fixed pointer 113 indicates the sum of the extra spaces thrown by the spacing-levers.

The graduated disk S9 and the graduated wheel 110 are used in conjunction in producing justified print from prepared copy. This conjoint use may be as follows, viz: Assuming each justified line to contain one hundred and thirty-two units of space, then when the last character of each line has been printed the dial S9 should register 132, or if it started at 132 and wasrun backward it should indicate at theviinish 0, to show that the lines are exactly o f the required length; but if the characters in words and the normal space between words of any particular line occupy a less number of units of space-as, for instance,

one hundred and twenty-iive units-and the copy indicates that seven extra units must be thrown in between words to produce a line of one hundred and thirty-two units in length, then the operator, when making the spaces between words, instead of striking the spacing-key controlling the normal space strikes one that controls one or more units in excess of the normal space,'and the extra amount of space thus thrown in is indicated by the wheel 110. Upon reaching the last space between words in the line, if the wheel 110 does not already indicate 7, the operator strikes a spacing-key controlling enough extra space to make up the required seven extra units of space, and then finishes the line of printing. If, upon reaching the last space betweenwords,

the operator sees by the indication of thev ICO wheel 110 that the required extra spaces have already been thrown, he uses the key controlling the normal space. Upon completion of the line of printing the indicators 89 and 110 are examined, and if the former-shows the line to be finished at the proper point and the latter that the number of extra units indicated by the copy have been added to the normal space between words it will be apparent that the work is correct and needs no prooffreading or correction. If, on the other hand,`the indicator shows the proper amount of extra space as being thrown in, but lthe indicator 89 shows that the line does not terminate at the proper point, but contains more o r less than the required number of units, the operators attention is thus called to the fact that there is an error somewhere in the last line of print, and by comparing the work with the copy he is enabled to locate and correct the error before proceeding further. Thus it will be seen that by the conjoint use of the indicators S9 and 110, when using prepared copy, the operator is enabled not only to justify the lines of printing, but to 'accomplish the justification without the work of proofreading and without loss of time.

The matrix carriage 7 has a lnovement lengthwise of the machine only, and is adsions in a line.

IIO

. 4 Y Gast/3 the lever is retracted by a spring 123, that is attached to a post 123 on a cross-bar of the carriage 7. The depression of the lever causes the /pawl it carries to engage the ratchetwheel and cause it to turn .the shaft 118, thereby causing the toothed wheels to engage the matrix-strip at its under side and advance it the proper distance to space for a line.

The piston 2O is made hollow for the sake of lightness, and the plunger 21 has an enlarged body 124, that screws into the piston and is held in position by a jam-nut 125. The lower end of the plunger has a tapering recess 126and its face surrounding the recess is reduced to a narrow edge 127. The stem 128 of the type-die has its upper end 129 of conical form to fit in and be engaged bythe walls of the plunger-recess 126, so as-to bring the axes of the plunger and die in line when in contact. This construction enables a die to be thrown under the impressing device While the latter is rapidly reciprocating and insures that itfwill either catch in the countersink 126, and thus be accurately depressed at the printing-point, or it will slip outside the plunger and be held there until thenext plunger reciprocation.

The die-stem 128 has a tiange 130 at one side, in which is secured a pin 131 parallel to the stem, and in the socket-piece 37 is a guidehole 132 for the pin. The die is supported in its socket by a spring 133, seated on the bottom of the socket and bearing against a collar 134.- on the die-stem. The lower end of the die is beveled, as shown at 135, to correspond with the countersunk guide-hole 11 in the plate overlying the matrix material. Adjacent to this countersink is a guide-hole 136 for the pin 131. The die is thus guided at its upper end by means of the recess in the plunger and at its lower end by the countersunk guide-hole and the pin and its guide-holes in the die-socket and plate, so as to insure its sides, and these are supported on the outside section 1 of the bed-plate by the four posts 139. The object of`this.construction is to enable the parts 1, 8, 9, and 12 to be removed without disturbing the drum 13 or the diecarrying levers 32, and so enabling the dies to be removed and repaired when desired.

In use the operation of the machine is as. follows: The plunger 2l being rapidly recip- 55, which transmits motion to the lever 51 and by the wire to the corresponding lever 48, thence through the rod 46 to the arm 3370i: the die-carrying lever 32. The latter lever is thus swung toward the center until its shoulder 43 comes in contactwit-hthebuffer 42, and before the die 'can be Withdrawn by releasing the key it is caught by the plunger 21 and is forced down through the guide-v hole 11 into the matrix material on the carriage 7. Immediately upon the release of the ykey and the rising of the plunger 21 the diecarrying lever 32 is drawn back against the ring 12 by the action of its spring 38. 'The depression of the lever 51 causes its clip 56 to descend upon the lever 57, over which it is located, and depress it. The lever 57 in turn `engages and depresses the pin 620n which it rests, and forces the lower Vend of the pin down through the slot in the bar 69 and into the path of the stepped lever 76, and this de pression of the lever 57 causes it to engage and depress the arm 66, and thus turn the sleeve 65 and with it the arm 67, which serves to slide the bar 69 toward the left. Such movement of the bar 69 frees the pawl 78 from engagement and causes the pawl'74 to engage the scape-wheel yand hold it vuntil the operating-key is released and the bar is permitted to be returned toward theright by its retracting-spring 84. Y The release of the pawl 78 allows the stepped lever 76 to be swung around by its spring 82 until the proper step 77 comes in contact with the particular pin 62 that has been depressed by the operation ofthe selected character-key. The result of this operation is that the escapement appropriate for the character selected occurs after the impression has been made instead yof before. In manipulating the spacing-keys-for throwing in extra spaces between words or' letters all of the operations follow that occur when a character-key is struck, except that a die is not presented to the printing-point, and the register-wheel 109 is'operated to indicate the sum of the spaces thrown;
