Specification of Letters Patent.
Patented Nov. 28, 1905.
Application filed June 13, 1903- Serial No. 161,344.
T0 (1.2] whom it may concern:
Be it known that I, ABNER GREENLEAF, a citizen of the United States, residing at'thc city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Justifying Mechanism for Composing-Machines, of which the following is a specification.
This invention consists in a mechanism for effecting the justification of lines of composition in composing-machines, such as type-setting, type-casting, and linotype machines.
The invention will be described as applied for casting justifying-spaces which are usable for justifying lines of printers type; but it will be understood that it is applicable to all classes of composing-machines.
In the accompanying drawings, Figure 1 is a side elevation of an apparatus embodying the invention. Fig. 2 is a front view of part of the apparatus shown in Fig. 1. Fig. 3 is a view partly in section on the line 3 3 of Fig. 1. Fig. 4 is a plan view of the justifiercylinders. Fig. 5 is a section on the line 5 5, Fig. 4. Figs. 6 and7 are details of the ratchetand-pawl mechanism.
Referringto the drawings, Fig. 2, the spacekey 1 is connected by link 2, lever 3, and link 4 with an arm 5, which is loose on shaft 6. The arm 5 carries a pawl 7, which moves a ratchet-wheel 8 one tooth or unit each time the space-key is depressed. A suitable holding-pawl 9 is provided for the ratchet-wheel. The ratchet-wheel 8 is fast on shaft 6, and on the shaft is a series of disks 10, Figs. 1 and 3, each disk being provided with a single tooth 11 and said teeth being arranged spirally about the shaft 6. The purpose of these teeth will be explained further on.
Adjacent to the shaft 6 is a block or casting 12, in which is mounted a series of small cylinders 13, all of exactly the same diameter. In the cylinders 13 are closely-fitting pistons 14. The lower ends of the cylinders open into a tubular reservoir 15, and the pistons preferably project into said reservoir when they are in their lowest or normal position. The reservoir 15 communicates with a large cylinder 16, in which there is a piston 17, connected with the piston-rod 18. The piston 17 is shown in Fig. 5 in its highest position. Below the lower end of the piston-rod, as shown in Fig. 5, is an outlet19, communicating with the upwardly-extending pipe 20, in which there is a valve 21. The reservoir 15 and the cylinder 16 and stand-pipe 20 are normally filled with suitable liquid, such as oil or glycerin, and the piston 17 is normally in its highest position, as shown in Fig. 5. lVhen in this position, any air or gas in the liquid will naturally pass out of the opening 19 and up the stand-pipe. The upper wall of the reservoir 15 is inclined to the horizontal, so that air and gas will not stand or be trapped in it.
Each of the pistons 14 is normally locked in its lowest position by a bolt 22, Fig. 3, which engages a neck near the upper end of the pis ton. Above the pistons 14 is a universal bar or head 23, which is connected to a slide 24, having a movement parallel with the movement of the pistons 14. On the under side of the head 23 are a series of sliding bolts 25, each adapted to slide into engagement with a second neck on its corresponding piston 14, thus locking the piston to the head 23. The bolts 22 and 25 of each piston are connected by a rocking lever 26 in such manner that when the bolt 22 is withdrawn from the piston the bolt 25 is engaged with it, thus freeing the piston from bolt 22, which locks it in stationary position, and locking it to the head so that they must move together. Each bolt 22 is engaged with the upper end of a lever 27, pivoted on a rod 28. The lower end of each lever 27 cooperates with one of the disks 10, and for this purpose it is provided with two curved surfaces corresponding to the periphery of the disk and an intermediate notch to receive the tooth on the disk. This engagement of the disk and lever is similar to the well-known Geneva-stop movement.
The operation of the device thus far as described is as follows: Each time the space-key is operated in composing a line the ratchetwheel 8 is rotated one tooth, carrying with it the shaft 6 and the disks 10. It is presumed that the parts stand in their normal position before commencing each line of composition, in which position all of the pistons 14 are down to their lowest limit and are locked by the bolts 22. When the shaft 6 is turned for the first space, one of the levers 27 is rocked and the corresponding piston 14 is unlocked from its stationary position and locked to the head 23. It follows that a number of pistons 14 corresponding to the number of wordspaces in a line will be released from their stationary position and locked to the head 23 and that the remaining pistons will be locked in their stationary lowest positions. If now the valve 21 be closed and the piston 17 depressed, the released pistons 14 will be raised, together with the head 23, and as they are all looked to the same part they will rise an equal distance. It will be evident that the amount of upward movement of the head 23 will be inversely as the number of pistons moving with said head-that is, for a given downward movement of the piston 17 there will be agiven upward movement of the head 23 if one piston 14 be released. If two pistons 14 be released, the movement of 23 will be one-half as great. If three pistons 14 be released, the movement of 23 will be one-third as great, &c. The teeth on the disks 1() are so arranged that one of the middle pistons 14 is first released. The pistons on opposite sides thereof are alternately released afterward, thus distributing the pressure on the head 23 uniformly. To economize space as much as possible, the pistons 14 are arranged in two rows, as shown in Fig. 4. it will be evident that the apparatus illustrated in Figs. 3, 4, and 5 is adapted to divide the shortage of a line by the number of word-spaces in the line, the shortage being represented by the movement of the piston 17, the number of word-spaces being represented by the number of pistons 14 released, and the quotient being represented by the movement of the head 23. For convenience of construction the cylinders 13 are made much smaller than the cylinder 16, thus imparting to the head 23 a movement greater than the actual quotient above referred to,but proportional to the quotient. If the pistons 14 and 17 were exactly of the same diameter, the movement of 23 would be exactly the quotient of the movement of 17 divided by the number of active pistons 14.
The justifier above described may be adapted to any composing-machine, such as a typesetting, type-casting, or a linotype machine. In the present case it is illustrated in connection with mechanism for setting a mold to cast justifying-spaces.
Referring to Fig. 1, 29 indicates a lever which is rocked after the keys for selecting or indicating a line of composition have been operated. Connected with the lever is a cam 30, which rocks the lever 31 during the first part of movement of lever 29 and holds said lever 31 stationary during the balance of said movement. The first movement of lever 31 through link 32 closes the valve 21, and thereafter said valve remains closed until the handle of lever 29 is again raised. To the inner or rear end of lever 29a second lever 33 is connected by link 34. The inner end of lever 33 carries a pin 35, which is pivotally connected to thelower end of a link 36. During the first movement of the lever 29 and while the valve 21 is being closed the link 36 moves down without effecting any operation. When the valve 21 is closed, the upper end of slot 37 in link 36 engages a pin 38 on an arm 39. The arm 39 then engages a pin 40 on segment 41, which segment is in mesh with rack-teeth on the piston 18. As the piston moves down under influence of lever 29 the segment 42 is rocked upward, rotating agear 43, fixed on a sleeve 44. The sleeve 44 carries a pinion 45, which meshes with a rack on the slide 46, which compresses the line of matrices or type 47 against an abutment 48, and thus the movement of the parts 35 to 46, inclusive, and of the piston 17 and rod 18 is proportional to the shortage of the line. The downward movement of the piston 17 produces an upward movement of the pistons 14, which have been locked to the head 23, and consequently the movement of the head 23 a distance which is proportional to the quotient of the shortage divided by the number of word-spaces-that is, proportional to the justifying-space required for the line. The movement of head 23 is communicated, by means of a rack 49, gear 50, and rack 51, to a pinion 52, which is fast on the shaft 53, upon which the sleeve 44 turns. Upon said shaft 53 is an arm 54, which engages a pin 55 on a sector-gear 56, which is loosely mounted on the shaft 53. The sector-gear 56 is" in mesh with a pinion 57 on a shaft 58, and on shaft 58 is a second pinion 59, which operates a slide 60, having-rack-teeth. The movement of the slide 60 for each line will be equal to or proportional to the justifying-space required for the line. As shown in Fig. 1, the slide 60 is integral with the body piece 61 of a mold, and its movement regulates the moldopening 62, in which justifying-spaces may be cast. It will be evident to those skilled in the art that the justifying mechanism above described may be used in any of the well known composing-machines by modifying the manner of applying it. After the body-piece 61 or the part controlling the justification for a line has been set by the downward movement of the handle 29 the handle is raised and the parts are restored to their initial or normal position, with the exception of the part 61 or other part controlling the justifier. The operator is thus enabled to proceed with the composition of a new line immediately after setting the justifier for the preceding line. The means for restoring the parts to normal position are as follows: After the justifier is set the handle 29 is raised to its uppermost position. This causes the pin 35 to engage the upper end of a slot 63 and raise a link 64, rocking a lever 65, which is connected by link 66 to a detentpawl 67. As shown, pawl 67 is mounted on an arm of an elbow-lever 68, pivoted at 69 to the main frame. In the short arm of the lever is pivoted a cam 70,- which is normally held stationary by the pawl 67 and which has a tendency to move into contact with the constantly-rotating roller 71, driven by pulleys 72, belt 73, and gears 74 75 from the driveshaft 76. When the pawl 67 is withdrawn from the pin on the cam 7 0, the cam rotates into contact with the roller 71 and the eccentricity of the cam causes it to rock the lever 68. When the cam has made a single revolution, it is again caught and held by the pawl 67.- The end of lever 68 is connected by spring-link 77 with slide 24:, which carries the head 23, and said head and the displaced pistons 14: are drawn down to their normal position. As these pistons 14: are drawn down the piston 17 is forced up. To assist in moving the piston 17 to normal position, a rocking lever 78 is connected at one end to slide 24, and at the opposite end it is connected by a link with the slide 79, operating under a toe or projection'80 on the piston-rod 18. The body-piece 61 may be returned to normal position by'hand or any suitable mechanical means. -A pin 81 on the lever 68 operates in a link 82, and when lever 68 reaches its lowest position link 82 is slightly drawn down, rocking a lever 83 and forcing up a slide 84, which raises the pawls 7 and 9 and releases the ratchet-wheel 8. A spring 85 on the shaft 6 returns said shaft to its normal or starting position, causing the bolts 22 to lock the pistons 14: in their lowest or normal position. The parts are thus all automatically returned to normal position and the composition of the succeeding line may be immediately commenced. The upward movement of the lever 29 opens the valve 21. The lever 29 is only momentarily held in its highest position, when it is ready to drop slightly to normal position, as shown in Fig. 1.
