IN'KING-ROLL TRUCK FOR PRINTING-PRESSES.
Specification of Letters Patent.
Application filed November 30, 1917. Serial No. 204,599.
controls the roll and holds it away from the type duringits travel in one direction, the
truck being operable to bring the roll to a position in which the roll engages the type when it travels in a reverse direction.
The roller to which the truck is applied is a supplementary or auxiliary roller which is operated and brought into contact with the type to ink them after the operation of the other rolls.
The object of an invention of this character is the even distribution of the ink. TVithout the supplemental roll the inking of the type surface is uneven by reason of the fact that during the first rotation of the ink rolls after leaving the ink disk the greater portion of the ink is deposited upon the uppermost or first type, the latter or subsequent type receiving only a comparatively small amount of the ink originally deposited'upon the rolls. The supplemental roll is kept raised from the face of the type after it leaves the ink disk, and is only per- I mitted to contact with the type upon the return stroke of the arm by which these rolls are carried. This insures a deposit of ink upon the lowermost type which results in an even distribution of ink upon all of the 7 type and insures uniform impressions.
It is an object of the invention to produce these and other advantages in a simple and expeditious manner without resulting in a corresponding reduction in efliciency.
The invention has as a further object certain details of construction which will be explained in detail in conjunction with the accompanying drawings, in which- Figure 1 is a sideelevation of a portion of a press having the invention applied thereto;" ,7
Fig. 2 is elevation of a portion of the structure shown in Fig. 1, showing the truck positioned upon the part of the press with whichit cooperates;
Fig. 3 is a central section of the truck shown in Figs. 1 and 2;
Fig. 4 is another section of the truck taken on line 4-4 of Fig. 5;
Fig. 5 is an end view of the truck; and
Fig. 6 is a central section of a modified form of the invention.
In the drawings the invention is illustrated as applied to a press of the type which employs a swinging frame 10 having the 1nk disk 11 and the swinging arms 12 to which the trucks are attached, which carry the ink rolls 13-13, and the supplementary roller 14. This frame 10 is actuated by the crank arm 15 connected to the gear 16, as is usual in this type of press. The swinging arms 12 carry the rollers 13-13 and supplemental roller 14' from the ink disk 11 across the face of the type and back again. These rollers 13 and 14 have trucks 16 and 17 respectively, provided at their opposite ends, which ride upon the tracks 18. The upper ends of these tracks terminate near the disk or plate 11 and the lower ends being beveled as shown at 19. This beveled portion 19 cooperates with the truck 17 of the supplementary roller 14 and actuates it and positions the roller 14 so that it engages the face of the type upon its movement in an upwardly direction. This position of the roller is maintained until it reaches the uppermost end of the track when the truck is brought into the path of the track and rides thereon during the downward travel thereof from the ink disk 11, holding the roller away from the face of the type. The truck generally designated 17 is mounted upon the end of the shaft 20 of the supplemental or auxiliary roller 14 by the member 21, which is made fast with the shaft 20 by the key 22. This key also limits the movement of the member 21toward the roller 14. The member 21 has a sleeve 23 which is passed over the end of the shaft 20. This substantially greater in width than the high tread 26 for the reason that greater tractionis necessary to operate the roller 14 when this portion rides against the track because when thisportion is in contact with the track the type are being inked by the supplementary roller 14, which is driven by this part of the truck.
This member 25 abuts against the flange 24, and is held against the same by the coiled springs 34. The portion 25 is provided with the apertures 3030 having the reduced portion 31. Into these bores are fitted the headed pins 32 one end of which .are driven into the flange 24 of the member 21. A coiled spring 34 is placed in the larger portion of the bores 30 3O and reacts between the head of the pin 32 and the shoulder 35 of said bore. This arrange ment tends to keep the collar having the treads 26 and 27 and the collar having the flange 24 together, as shown in Fig. 3, but permits them to separate when caused to do so by the beveled portion 19 of the tracks 18. These pins 32 further cause the two members 23 and 25 and their associated parts to rotate together to drive the roller 14, eliminating any relative rotation and the necessity of additional keys, etc., for this purpose.
An arrangement is provided whereby a relative adjustment of the parts 23 and 25 may be had, which is of advantage in that the treads may be arranged so as to properly cooperate with tracks of various widths. Should a condition arise in which the truck had to'be positioned on the shaft 20 approximately in the relation shown in Fig. 3, and the track 18 was found to be somewhat wider than illustrated, under these condi-' portion 19 for the proper operation of the device. To arrange for this contingency the member 21 1s provided with the adjusting screws 34 and the set screw 35, which may be operated to separate the members 21 and 25. The member 21 being fixed would naturally cause the member 25 having the treads to be shifted oradjusted with relation to the track 18. These set screws may be arranged in the flange 24 instead of in the member having the treads 26 and 27. V
In the modified form shown in Fig. 6, a single coiled spring 36 is used and the pins 32 are dispensed with. This structure contemplates the use of a collar 37 having aflange 38 and the screw threaded end portion 39. Over this collar 37 is passed the portion 40 having the treads 41 and 42, and the inwardly projecting flange 43. This flange 43 and the flange 38 form a recess which houses the coiled expansion spring 36, which reacts against these flanges.
I adjusted by the adjusting screws 47 similar to those shown and described in connection with the structure illustrated in Figs. 3 and 4.
The operation of the trucks which control the auxiliary rolls 14 is substantially as follows: As the inking rollers leave the disk 11in their downward travel with the rollers l3 13, the high part of the truck of the auxiliary roller rides over the uppermost end and upon the track 18, lifting this roller away from the type and holding it out of contact while the rollers 13-13 contact with the type and ink them. After these inking rollers 13-13 leave the printing surface of the type and are about to begin their return movement,.the high part of the trucks engages the beveled portion 19 of the track 18 and slips off. As soon as this occurs the low tread part of the trucks engages the top of the track, while the high part engages and travels along the side thereof, and as the rollers including the auxiliary roller 14 travel upwardly, the roller 14 is brought for the first time "into contact with" the printing surface of the type, distributing the ink which it received from the disk 11 upon the lowermost type. This insures the proper and even inking of the type so that when an impression is taken, all of the type will be equally pronounced. l/Vhile the roller 14 is inking the. type, the high part of the truck travels along the side of thetrack 18. This brings the low tread against. the track, which furnishes the traction necessary to rotate it. At this time the springs are compressed by virtue of the fact that bothof'these treads are secured by the pins to the part which is, immovably fixed to the shaft of the roller 14. When the high treadreac'hes the uppermost end of the track'i. passes from the side'of the track into the path 'thereof,'this being caused by the expansion of the springs, and upon its travel from the inking disk 11 the inking roller 14 will be lifted away from the face of the typeand the subsequent action will be a repetition of that just described.
Having thus described the invention what i combination of a truck having a high and low tread construction to cooperate with a track to raise and lower the truck, said truck being secured to an end of a roller and having means for adjusting the truck with relation to the track, said means being movable with the truck when same is moved to present the high and low treads to the track.
