- My invention has reference to embossing and printing presses, and consists of certain improvements which are fully Set forth in the following specification and shown in the accompanying drawings, which form a part thereof.
- the object of my invention is to provide an organized machine adapted to embossing and printing, driven by power, whereby speed, accuracy, and perfection of work may be accomplished.
- my object is to provide such features of construction as will enable the machine to be accurate in the movement of its operative parts, adjustable to meet all material requirements, and durable in construction.
- My invention consists of an embossing and printing press containing the following features of construction: first, a toggle operated plunger for giving the impression to the dies having an adjustable abutment, combined with an adjustable bushing between the abutment and the main frame of the machine whereby the rotation of the bushing causes an adjustment of the abutment in the direction of the thrust of the plunger; second, a vertically reciprocating wiper, combined with hand controlled ad justing devices for adjusting the reciprocation, whereby the bottom of the wiper may be caused to move to different levels to suit the level of the die of the reciprocating carriage; third, in combination with a web of wiping material and the wiper therefor, of means operating' upon the inked surface of said web for applying a solvent thereto before the same is wound upon a mandrel; fourth, an inliing roller combined with means for giving to it a reciprocating movement over the carriage and the die thereon, combined with means for spring pressing the inking roller toward it and hand controlled devices for regulating the spring controlled means,
- locking device for locking the carriage under the plunger at time of giving the impression which comprises locking projections on a swinging ⁇ link which engage a fixed stud during the time the lever is traveling after the beginning of the dwell or stationary period of the carriage takes place, and which disengage the stud when the link is swung upward into the position for projielling the carriage; sixth, means for feeding the wiping web from one mandrel to another, which consists of a continually rotating mandrel to wind up the web and an intermittently feeding roller for controlling the supply of the web to the continuously rotating mandrel, and power devices for intermittently rotating the feeding roller operated by the shaft from which. power is derived for operating the carriage, plunger, inlring devices, and wiper of the machine.
- FIG. 8 is a front elevation of the lower portion o't the machine, with part in section, showing the loclting means for the die carriage;
- Figs. 9 and l0 are perspective views of the locking devices shown in Fig. 8;
- Fig. l1 is an elevation of the inl; applying roller and its supporting devices;
- Fig. 19. is a side elevation of the same;
- Fig. 13 is a sectional elevation of a portion of the same; and
- Figs. le and l5 are plan views of details of the same.
- This main frame is the main frame of the machine and as shown consists of two side frames connected at intervals by cross frames.
- This main frame may be of any suitable construction.
- a guide for a vertical die carrying plunger 13 This plunger is forced upward normally by a sprino' 14. It is connected at the top with an acjustable abutment bloc 22 by means of a toggle 15 having the roller 16 at its hinge.
- This toggle is straightened by means of a cam 17 on the shaft 21 operating in connection with the roller 16, and this is the operation that takes place when the impression is being made by the' embossing die.
- a link 18 is provided from the hinge of the toggle and this is furnished with a roller 19 which is operated by a cam 20 also carried by the cam shaft 21.
- the hinge of the toggle is moved to the left in Fig. 2 and therefore draws the plunger 13 upward.
- two such links 18, rollers 19, and cams 2O are employed where great strength is required, one being preferably arranged upon each side of the central embossing cam 17.
- the abutment block 22 is more clearly shown in Figs. 5 and 6. It is circular in plan and is screw-threaded, so as to be adjustably held within a bushing 23 which is carried by a frame 27 and held between it and the main frame 2 above.
- This bushing 23 is provided with gear teeth 24 with which engage a pinion 25 adapted to be rotated by a hand wheel 26. It will be seen that by rotating the hand wheel 2G, the bushing will be rotated, and as the abutment block 22 cannot rotate, it is caused to be raised or lowered according to the direction of rotation of the bushing.
- the bushing may be clamped against movement by the following means
- the plate or frame 27 is split at one side and is provided with a stud 28 upon which a clamping nut 29 is screwed. By turning the nut 29, the plate 27 grips the bushing ⁇ and prevents it being turned either accidentally or by the action of the machine during the printing operation.
- the ink applying roller 31 which is preferably made with a plush surface, so that the ink may enter the recesses in the die.
- This ink applying roller receives the ink from a rotating ink roller 3() revolving in an ink well, it being driven by means of a sprocket wheel 67 and a sprocket chain G6 receiving power from a sprocket wheel G5 on the driving shaft G4, as shown in Fig. 1.
- the ink applying roller 31 is flexibly' carried on the upper end of the rocker arms 32, and these are rocked by links 33, bell cranks 34, rod 35, and cam 36 which is secured to the :am shaft 21. This cam is so timed as to its action that the ink applying roller 31 has been moved forward and held stationary at the time the carriage 4 is being moved backward and forward under it.
- the wiper 37 is raised so as not. to be in contact with the die during its travel to position to receive the ink, but when the carriage is moved forward toward its printing position, the wiper 37 is lowered for the purpose of wiping the surplus ink away from the surface of the die before the embossing and printing take place.
- each side of the machine there is a frame 45 which is guided vertically in guides 48 on the main frame 2 so that said frames may be reciprocated vertically.
- These frames are also provided with vertical slots 4b' through which retaining bolts 47 pass for holding them in position upon the main frame 2 and also for sustaining them when ⁇ cause.
- These frames l5 are each provided with two vertical studs 42. Sustained and guided upon these studs is the wiper plate 37, said plate resting upon springs 43e and held downward by springs 43, the tension of these springs being adjusted by hand nuts lll provided with clamping devices to hold them in their adjusted positions. By this means, the wiper is permitted to adapt itself to the die.
- 6l is a supporting shaft having a roll of paper in the form of a web, and this web, indicated at 5S, is guided over the rod 60, thence between the feeding rollers 59, 59a, thence over a roller 5athence under the forward end of the wiper pad, thence under said wiper pad, thence upward over the lubricating roller 55, thence backward around the rod 62a to the winding shaft 62.
- the tendency of the winding shaft 62 is to continually wind up the paper, but the feeding of the paper web is intermittently performed by means of the feed roller 59 which is given an intermittent rotary motion, there being enough paper fed at each operation to present enough clean surface to insure the wiping of the die to the requisite degree.
- the roller 59 is provided with a ratchet wheel 7l (Fig. l) and this is rotated intermittently by a pawl carried by a wheel 69 having a rotary reciprocating motion.
- This wheel 69 is rotated in one direction by the counterweight 78 and band 77, and in the other direction by means of the chain 72, the bell crank 73, the rod 7st, and the rocking arm 7 o, which latter is secured to the rock shaft 7 6 receiving its rocking motion from the lever 5 as described.
- the connection of the chain 72 with the bell crank lever 73 is vertically adjustable upon the long arm of said bell crank so as to vary the extent of throw of the lever.
- l provide a guide roller 55, over which the paper web passes immediately after leaving the wiper, and this roller is caused to run in contact with a roller rotating in a well o7 in which an oil or other solvent for the ink may be placed. If oil is employed, the paperis thoroughly oiled before passing to the winding mandrel and in this manner the several layei's of the web are also prevented from adhering to each other when being wound upon the mandrel.
- the winding mandrel receives its power by means of a sprocket chain 63a, driven from a sprocket wheel 65a and driving a sprocket wheel 63, frictionally carried by the mandrel 62 in any suitable manner so that there is always a tendency for the mandrel to rotate to take up all surplus paper, but the winding capacity of which is controlled by the operation of the feeding roller 59.
- Winding mandrels of this character are well U known and any suitable device of this nature may be employed.
- a sleeve 9 1 is provided with lateral arms 50 at each end which are connected by means of links t9 By rocking the sleeve 91, it is evident that the wiper will be reciprocated vertically.
- the sleeve is provided with an arm 92 4 and 7) which is connected to a link 98 extending upward and guided by the cam shaft 21.
- This link is provided with a roller Set that works in a cam 96, said cam being secured to the shaft 21. TWhen the cam shaft 21 is rotated, it is evident that the sleeve 91 will be rocked; and therefore, by properly proportioning the cam, the vertical. reciprocations of the wiper will be commensurate with and equal in number to the reciprocations of the carriage, and so that as the carriage moves toward the inking devices, the wiper will be elevated, and when it moves from the inking devices, the wiper will be depressed into wiping position. As the ordinary height of the die may vary with diderent dies, it becomes necessary to provide suitable means for automatically7 adjusting the location of the wiper so that in its reciprocations it will always properly coperate with the die.
- I provide an eccentric shaft which is journaled in the main frame 2 and supports the sleeve 91 on its eccentric portion.
- This shaft 90 is secured at one end to a segmental gear 51, which engages a worm 52, controlled by a hand wheel 53.
- the eccentric shaft may be adjusted into diderent positions, the position shown in Figs. 3 and 4 being the yintermediate one. Looking at Fig. 3, if the eccentric shaft is rotated to the right, then the reciprocation of the wiper will take place'at a lower level. If on the other hand, the eccentric shaft is turned to the left, then the reciprocation of the wiper will take place at a higher level.
- the shaft 102 is loosely journaled in the ends of the rocking arms 32. Secured to this shaft 102 is an arm 103 having a hole near its end. Extending through this hole is a screwthreaded rod 105 which screws into a pivoted lnut 32a on o-ne of the arms 32. Rod 105 is provided with a rigid collar 106 against which the arm 103 rests and upon which it is spring pressed by a coiled spring 104 on the upper extension of the screwthreaded rod 105.
- a hand nut 113 is secured to the upper end of each bolt for raising it against the action of the spring when releasing the shaft.
- Pins 113"l are secured to the nuts 113 so that when the bolts are fully raised and slightly turned, they are held in such elevated position as will permitl the shaft to be readily withdrawn. Furthermore. when the bolts are in locking position, the pins 113 are received in grooves 113b which prevent the bolts l'roin turning and thereby maintain the dat side of the bolts presented to the shaft 31, as will he readily understood from Fig. 13.
- lllheels 11S may bc secured to the shaft 31n for the purpose of engaging the wheels 11 on the side of the die clamp 11 of the carriage 4 so that the inking roller 31 will be elevated until it over the rear end of the die clamp and will then be lowered into inking contact with the die, and again elevated out of contact with the forward part of the die clamp. and vice versa.
- the ink is thoroughl applied to the die and not to any other part of the machine.
- the flexible supjiiorting of the inking ⁇ roller combined with the means for relatively adjusting its distance with respect to the die carryingea Triage which l have here shown and described is exceedingly effective, but it is evident that the particular adjustments involved may be secured in many other modiied forms of apparatus.
- l have provided mechanism shown in Figs. 2, 8, 0, 10.
- the link 7, heretofore described, is secured to a locking head 97 which is provided with curved segmental parts 0S separated by segmental notches 90.
- Engaging the space between these segmental projections 98 and adapted to work through the lil() atraer segmental spaces 99 is astud 101 having a shank 100 which is rigidly bolted to the main frame.
- the stud 101 is elongated in one direction, and its length is exactly equal to the distance between the segmental pro jections 98 of the head 97 on the line of greatest diameter, so that when the stud is in a horizontal position, as indicated in dotted lines in Fig. 2, the projections 9S are respectively in Contact with its opposite ends. 1n this manner, the carriage is rigidly locked in position under the plunger 13 when the parts are as indicated in lig. 2. lllhen the lever is moved backward so as to swing the link i' upward and rearward, it will turn the head. 97 into a position which brings the segmental recesses 99 in horizontal alinement with the stud 101, so that a backward pull upon the carriage will cause the head to pass freely over the stud 101.
- Another feature is thatwhere, heretofore the feed rolls for the web have been caused to act upon it between the wiper and wind! ing mandrel l place them so as to act on the paper web before it reaches the wiper and provide means to prevent the web from being pulled backward from the winding inandrel.
- the advantage of this lies in the fact that the feeding rollers act upon ay clean por tion of the web, and there is no danger of the same sticking to the roller or of being ruptured.
- rlhe preferred -form of winding mandrel is shown in Fig. 16.
- the sprocket wheel 63 is inount d in its bearings 03g to rotate freely.
- the chuck G81 carries the square winding mandrel 62 in a detachable manner.
- rl ⁇ his chuck is on a shaft 63C extending through the hub of the sprocket wheel 03.
- rubber or leather friction ring 63d is interposed between the face of the sprocket wheel 03 and chuck G3i and the latter is pressed into frictional contact with it b y the spring 63 surrounding its shaft 63@ and acting upon a nut @3f which may be adjusted to vary the driving tension between the sprocket wheel 03 and chuck 03h.
- the width of the webs being changed to suit the width of the dies from which the printing is to be written.
- A. pawl 63h acts upon the toothed periphery of the chuck to prevent it being rotated by any pull upon the web which would tend to unwind the mandrel 62. The cause of such backward pull is the friction upon the web at the time the die is being wiped by the wiper.
- Vlhile lf have shown the details of con struction which l have preferred and employed in the commercial forni of press embodying my improvements, do not confine myself to these specific details, as it is eviw dent to one skilled in the art that the same general adjustments may. be accomplished by other forms of the said details without departing from ⁇ the spirit of the invention involved in them.

To all 'whom it may concern: A
Be it known that f, EDWARD M. Locriwoon, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Embossing and Printing Presses, of which the following is a` specification.
My invention has reference to embossing and printing presses, and consists of certain improvements which are fully Set forth in the following specification and shown in the accompanying drawings, which form a part thereof.
The object of my invention is to provide an organized machine adapted to embossing and printing, driven by power, whereby speed, accuracy, and perfection of work may be accomplished.
lli/fore specifically, my object is to provide such features of construction as will enable the machine to be accurate in the movement of its operative parts, adjustable to meet all material requirements, and durable in construction.
My invention consists of an embossing and printing press containing the following features of construction: first, a toggle operated plunger for giving the impression to the dies having an adjustable abutment, combined with an adjustable bushing between the abutment and the main frame of the machine whereby the rotation of the bushing causes an adjustment of the abutment in the direction of the thrust of the plunger; second, a vertically reciprocating wiper, combined with hand controlled ad justing devices for adjusting the reciprocation, whereby the bottom of the wiper may be caused to move to different levels to suit the level of the die of the reciprocating carriage; third, in combination with a web of wiping material and the wiper therefor, of means operating' upon the inked surface of said web for applying a solvent thereto before the same is wound upon a mandrel; fourth, an inliing roller combined with means for giving to it a reciprocating movement over the carriage and the die thereon, combined with means for spring pressing the inking roller toward it and hand controlled devices for regulating the spring controlled means, whereby the roller may be adjusted normally to vary its elevation with respect to the carriageupon which the die is clamped; fifth, a. locking device for locking the carriage under the plunger at time of giving the impression which comprises locking projections on a swinging` link which engage a fixed stud during the time the lever is traveling after the beginning of the dwell or stationary period of the carriage takes place, and which disengage the stud when the link is swung upward into the position for projielling the carriage; sixth, means for feeding the wiping web from one mandrel to another, which consists of a continually rotating mandrel to wind up the web and an intermittently feeding roller for controlling the supply of the web to the continuously rotating mandrel, and power devices for intermittently rotating the feeding roller operated by the shaft from which. power is derived for operating the carriage, plunger, inlring devices, and wiper of the machine.
My invention also embodies details of construction which, together with the features above specified, will be better understood by reference to the drawings, in which:
Figure l is a side elevation of my improved embossing and printing machine; Fig. 2 'is a sectional side elevation of the same; Fig. 3 is a sectional elevation on line cc-oi of i showing my improved wiping devices; Fig. Ll is a plan view of the same; Fig. 5 is a sectional elevation of the reciprocating embossing die plunger and means for operating` and adjusting it; lEig. 6 is a plan view of the same; Fig. i' is a cross sectional view showing a detail of the power devices for vertically reciprocating the wiper; Fig. 8 is a front elevation of the lower portion o't the machine, with part in section, showing the loclting means for the die carriage; Figs. 9 and l0 are perspective views of the locking devices shown in Fig. 8; Fig. l1 is an elevation of the inl; applying roller and its supporting devices; Fig. 19. isa side elevation of the same; Fig. 13 is a sectional elevation of a portion of the same; and Figs. le and l5 are plan views of details of the same.
2 is the main frame of the machine and as shown consists of two side frames connected at intervals by cross frames. This main frame may be of any suitable construction.
3 are two guides arranged horizontally and adapted to guide the reciprocating carriage 4 which is provided with the adjustable die clamp 11. This carriage 4 is connected with a rocking lever 5 by means of links 6 and 7 which are hinged together upon a transverse shaft 7a forming in effect a toggle. The ends of the shaft 7 u are provided with rollers S which run in guideways 9 and 10, the part 9 thereof being hori- Zontal, whereas the part 10 is curved and concentric with the axis of the hinge joint vof link 7 with the carriage 4. By this means, when the carriage is in the position shown in Fig. 2, the backward movement of the lever 5 will first cause the link 7 to swing backward and upward without disturbing the carriage, and subsequently when the rollers 8 pass above the curved part 10 of the guides, the links 7 and 6 will have straightened to approximate alinement and a further movement of the lever 5 will cause the carriage 4 to be moved backward under the wiper and toward the ink-well.
Power is applied to reciprocate the lever 5 from the band wheel 68 as follows: The band wheel 68 rotates the shaft 64 and this, through a pinion 83 and gear S4, rotates a shaft 82. By means of a clutch 87, this shaft 82 rotates, through the medium of pinion 35 and gear 86, a cam shaft 21. At one end of the cam shaft is a crank which, by the link 88, operates rocker arm 89 secured to a rock shaft 79 upon which the rocker arm 80 is secured. A link S1, hinged to the lever 5 and forming a detachable connection'with the rocker arm S0, enables the lever 5 to be rocked synchronously with the rocking of the arm S0.
Arranged at the front and upper portion of the machine at 12 is a guide for a vertical die carrying plunger 13. This plunger is forced upward normally by a sprino' 14. It is connected at the top with an acjustable abutment bloc 22 by means of a toggle 15 having the roller 16 at its hinge. This toggle is straightened by means of a cam 17 on the shaft 21 operating in connection with the roller 16, and this is the operation that takes place when the impression is being made by the' embossing die. To raise the plunger 13, a link 18 is provided from the hinge of the toggle and this is furnished with a roller 19 which is operated by a cam 20 also carried by the cam shaft 21. By this mechanism, the hinge of the toggle is moved to the left in Fig. 2 and therefore draws the plunger 13 upward. Ordinarily, two such links 18, rollers 19, and cams 2O are employed where great strength is required, one being preferably arranged upon each side of the central embossing cam 17.
The abutment block 22 is more clearly shown in Figs. 5 and 6. It is circular in plan and is screw-threaded, so as to be adjustably held within a bushing 23 which is carried by a frame 27 and held between it and the main frame 2 above. This bushing 23 is provided with gear teeth 24 with which engage a pinion 25 adapted to be rotated by a hand wheel 26. It will be seen that by rotating the hand wheel 2G, the bushing will be rotated, and as the abutment block 22 cannot rotate, it is caused to be raised or lowered according to the direction of rotation of the bushing. This enables a very accurate adjustment of the plunger 13 to suit the thickness of the dies and to enable exactly the right pressure to be applied without danger of injury to any of the working` parts or to the dies. Then the adjustment. is made, the bushing may be clamped against movement by the following means The plate or frame 27 is split at one side and is provided with a stud 28 upon which a clamping nut 29 is screwed. By turning the nut 29, the plate 27 grips the bushing` and prevents it being turned either accidentally or by the action of the machine during the printing operation.
When the carriage 4 with the die clamp thereon is moved backward, the ink is applied to the surface of the die by means of the ink applying roller 31 which is preferably made with a plush surface, so that the ink may enter the recesses in the die. This ink applying roller receives the ink from a rotating ink roller 3() revolving in an ink well, it being driven by means of a sprocket wheel 67 and a sprocket chain G6 receiving power from a sprocket wheel G5 on the driving shaft G4, as shown in Fig. 1. The ink applying roller 31 is flexibly' carried on the upper end of the rocker arms 32, and these are rocked by links 33, bell cranks 34, rod 35, and cam 36 which is secured to the :am shaft 21. This cam is so timed as to its action that the ink applying roller 31 has been moved forward and held stationary at the time the carriage 4 is being moved backward and forward under it.
Then the carriage 4 is moved backward, the wiper 37 is raised so as not. to be in contact with the die during its travel to position to receive the ink, but when the carriage is moved forward toward its printing position, the wiper 37 is lowered for the purpose of wiping the surplus ink away from the surface of the die before the embossing and printing take place.
I will now describe the construction and operation of the wiping devices, referring more particularly to Figs. 2, 3, 4 and 7.
At each side of the machine, there is a frame 45 which is guided vertically in guides 48 on the main frame 2 so that said frames may be reciprocated vertically. These frames are also provided with vertical slots 4b' through which retaining bolts 47 pass for holding them in position upon the main frame 2 and also for sustaining them when `cause. These frames l5 are each provided with two vertical studs 42. Sustained and guided upon these studs is the wiper plate 37, said plate resting upon springs 43e and held downward by springs 43, the tension of these springs being adjusted by hand nuts lll provided with clamping devices to hold them in their adjusted positions. By this means, the wiper is permitted to adapt itself to the die.
38 is a heavy cloth, one end of which is clamped at le() to the top of the wiper plate 37, and which cloth extends under the wiper plate and over the opposite end, and is put under tension by a rotary shaft having prongs and provided with a locking device as shown at el in Fig. 3. lnterposed between the said cloth or web 38 and the bottom of the wiper plate 37 is a filling 39 of gro-und cork or other elastic substance. This pad, formed by the parts 3S and 39, has its ends tapering and more particularly the rear end so as to permit the passage of the die while applying a considerable pressure.
6l is a supporting shaft having a roll of paper in the form of a web, and this web, indicated at 5S, is guided over the rod 60, thence between the feeding rollers 59, 59a, thence over a roller 5athence under the forward end of the wiper pad, thence under said wiper pad, thence upward over the lubricating roller 55, thence backward around the rod 62a to the winding shaft 62. The tendency of the winding shaft 62 is to continually wind up the paper, but the feeding of the paper web is intermittently performed by means of the feed roller 59 which is given an intermittent rotary motion, there being enough paper fed at each operation to present enough clean surface to insure the wiping of the die to the requisite degree. The roller 59 is provided with a ratchet wheel 7l (Fig. l) and this is rotated intermittently by a pawl carried by a wheel 69 having a rotary reciprocating motion. This wheel 69 is rotated in one direction by the counterweight 78 and band 77, and in the other direction by means of the chain 72, the bell crank 73, the rod 7st, and the rocking arm 7 o, which latter is secured to the rock shaft 7 6 receiving its rocking motion from the lever 5 as described. The connection of the chain 72 with the bell crank lever 73 is vertically adjustable upon the long arm of said bell crank so as to vary the extent of throw of the lever. This is shown at 73a and it is evident that by adjusting this connection with the chain nearer to the pivot point of the bell crank lever, the smaller will be the rotation of the feeding roller 59, and consequently, the shorter will be the length of the paper web 58, which is fed under the wiper at each inking operation of the die. lt is evident that various Vwith the frames 45.
other means for causing a rotary recipro* eating motion may be employed for operating this feeding roller in lieu of that shown.
is the paper web takes up a gieat deal of surplus ink from the die, it is desirable to prevent the said ink causing the paper web to adhere to the guides leading it to the winding mandrel 62. For this purpose, l provide a guide roller 55, over which the paper web passes immediately after leaving the wiper, and this roller is caused to run in contact with a roller rotating in a well o7 in which an oil or other solvent for the ink may be placed. If oil is employed, the paperis thoroughly oiled before passing to the winding mandrel and in this manner the several layei's of the web are also prevented from adhering to each other when being wound upon the mandrel.
The winding mandrel receives its power by means of a sprocket chain 63a, driven from a sprocket wheel 65a and driving a sprocket wheel 63, frictionally carried by the mandrel 62 in any suitable manner so that there is always a tendency for the mandrel to rotate to take up all surplus paper, but the winding capacity of which is controlled by the operation of the feeding roller 59. Winding mandrels of this character are well U known and any suitable device of this nature may be employed.
l have heretofore referred to the vertical reciprocation of the wiper so as to clear the die when the carriage is traveling backward to receive the ink and to be depressed into contact with the die after the inking and .on its way to the forward part of the machine under the reciprocating plunger 13, and l will now describe the means which I employ for accomplishing this result. A sleeve 9 1 is provided with lateral arms 50 at each end which are connected by means of links t9 By rocking the sleeve 91, it is evident that the wiper will be reciprocated vertically. The sleeve is provided with an arm 92 4 and 7) which is connected to a link 98 extending upward and guided by the cam shaft 21. This link is provided with a roller Set that works in a cam 96, said cam being secured to the shaft 21. TWhen the cam shaft 21 is rotated, it is evident that the sleeve 91 will be rocked; and therefore, by properly proportioning the cam, the vertical. reciprocations of the wiper will be commensurate with and equal in number to the reciprocations of the carriage, and so that as the carriage moves toward the inking devices, the wiper will be elevated, and when it moves from the inking devices, the wiper will be depressed into wiping position. As the ordinary height of the die may vary with diderent dies, it becomes necessary to provide suitable means for automatically7 adjusting the location of the wiper so that in its reciprocations it will always properly coperate with the die. To accomplish this, I provide an eccentric shaft which is journaled in the main frame 2 and supports the sleeve 91 on its eccentric portion. This shaft 90 is secured at one end to a segmental gear 51, which engages a worm 52, controlled by a hand wheel 53. By turning the worm, the eccentric shaft may be adjusted into diderent positions, the position shown in Figs. 3 and 4 being the yintermediate one. Looking at Fig. 3, if the eccentric shaft is rotated to the right, then the reciprocation of the wiper will take place'at a lower level. If on the other hand, the eccentric shaft is turned to the left, then the reciprocation of the wiper will take place at a higher level. It is therefore evident that while the extent of reciprocation is substantially the same for all adjustments, the maximum point of depression may be made to vary through a wide range, and consequently compensate for all sizes or thicknesses of dies which may be secured to the carriage 4. It is evident that while this particular mode of adjusting the reciprocating devices is well suited to the purposes of the invention, other means may be employed for accomplishing the same results in substantially the same manner.
Referring now to the means for flexibly supporting the inking roller 31, l will refer more specifically to Figs. 11 to 15. The shaft 102 is loosely journaled in the ends of the rocking arms 32. Secured to this shaft 102 is an arm 103 having a hole near its end. Extending through this hole is a screwthreaded rod 105 which screws into a pivoted lnut 32a on o-ne of the arms 32. Rod 105 is provided with a rigid collar 106 against which the arm 103 rests and upon which it is spring pressed by a coiled spring 104 on the upper extension of the screwthreaded rod 105. By turning the rod 105 it is screwed into the nut 32"L and therefore will cause the shaft 102 to take different positions of adjustment. To lock the rod 105 against accidental unscrewing, l provide a collar 107 having one er more teeth 10i421 which may engage one or more of the recesses 108 on the arm 103. furthermore is carried on the rod by a spline connection, so that it does not turn on the rod, but will rotate with it and has capacity f for longitudinal adjustment.
Secured to the shaft 102 are arms 11T, and these arms are each provided with lateral projecting pins 117% Loosely sleeved upon the shaft 102 are two bearings 109 which are provided with transverse apertures 114 into which the lateral pins 11721 eX- tend with freedom of considerable motion (Fig. 13). Plungers 115 carried by the bearings 109 are spring pressed upward by springs 116 so as to make a spring support The collar against downward thrust by the pins 117. The bearings 109 have notches 110 for receiving the ends of the shaft 31a carrying the inking roller 31. The shaft 31a is locked in position in the bearings by spring bolts 111 which are pressed downward by coiled springs 112. A hand nut 113 is secured to the upper end of each bolt for raising it against the action of the spring when releasing the shaft. Pins 113"l are secured to the nuts 113 so that when the bolts are fully raised and slightly turned, they are held in such elevated position as will permitl the shaft to be readily withdrawn. Furthermore. when the bolts are in locking position, the pins 113 are received in grooves 113b which prevent the bolts l'roin turning and thereby maintain the dat side of the bolts presented to the shaft 31, as will he readily understood from Fig. 13. lt will now be understood that if a pressure is applied to the roller 31 upward, the bearings 109 will rock upon the shaft 102 and this up 'ard movement will be resisted by the coiled springs 11G so that the inking roller 31 will be elastically supported` and hence. will be caused tO follow any level or irregularity in the surface of the die to which it is applying ink. illoreover, the normal level of this inkine' roller is readily adjusted by the screw rod which adjusts the shaft 102 and thereby changes the normal position of the bearings 100 with relation to the level of the die carriage. lllheels 11S may bc secured to the shaft 31n for the purpose of engaging the wheels 11 on the side of the die clamp 11 of the carriage 4 so that the inking roller 31 will be elevated until it over the rear end of the die clamp and will then be lowered into inking contact with the die, and again elevated out of contact with the forward part of the die clamp. and vice versa. In this way, the ink is thoroughl applied to the die and not to any other part of the machine. The flexible supjiiorting of the inking` roller combined with the means for relatively adjusting its distance with respect to the die carryingea Triage which l have here shown and described is exceedingly effective, but it is evident that the particular adjustments involved may be secured in many other modiied forms of apparatus.
1n the printing operation, it is most essential that the carriage 4 shall be locked in fixed position at the moment that plunger 13 is descending to `give the impression. and to accomplish this in an automatic manner, l have provided mechanism shown in Figs. 2, 8, 0, 10. The link 7, heretofore described, is secured to a locking head 97 which is provided with curved segmental parts 0S separated by segmental notches 90. Engaging the space between these segmental projections 98 and adapted to work through the lil() atraer segmental spaces 99 is astud 101 having a shank 100 which is rigidly bolted to the main frame. The stud 101 is elongated in one direction, and its length is exactly equal to the distance between the segmental pro jections 98 of the head 97 on the line of greatest diameter, so that when the stud is in a horizontal position, as indicated in dotted lines in Fig. 2, the projections 9S are respectively in Contact with its opposite ends. 1n this manner, the carriage is rigidly locked in position under the plunger 13 when the parts are as indicated in lig. 2. lllhen the lever is moved backward so as to swing the link i' upward and rearward, it will turn the head. 97 into a position which brings the segmental recesses 99 in horizontal alinement with the stud 101, so that a backward pull upon the carriage will cause the head to pass freely over the stud 101. ln this manner, the carriage is released or unlocked whenever the link 7 is swung to approximately a horizontal position, butis always locked when the said link is in a vertical position. llt is evident that this mechanism is in effect the movement of the parts 98 with the link 7 as a bolt to engage an obstruction found in the part 101. Zthe parts 98 therefore constitute in effect curved bolts which engage opposite sides of the stud 101 when locking the carriage in position.
lferetofore, in presses of this character, considerable diiiiculty has been experienced in properly feeding the wiping web and l have provided special means which greatly improves the control and operation of the web. It will be evident that the downward movement of the wiper 3i would stretch and break the paper if the rollers 54 and 55 were supported in stationary bearings and this I obviate by placing these rollers upon the reciprocating frames d5 so that they move synchronously with the wip-er plate. The paper web is led from the feed rolls 59 to the guide roller 5d and also from the roller to the guide rod 62a in a horizontal direc tion so that the vertical reciprocations of the rollers 5d and 55 do not put the web under any tension over that required for its normal feeding.
Another feature is thatwhere, heretofore the feed rolls for the web have been caused to act upon it between the wiper and wind! ing mandrel l place them so as to act on the paper web before it reaches the wiper and provide means to prevent the web from being pulled backward from the winding inandrel. The advantage of this lies in the fact that the feeding rollers act upon ay clean por tion of the web, and there is no danger of the same sticking to the roller or of being ruptured.
rlhe preferred -form of winding mandrel is shown in Fig. 16. The sprocket wheel 63 is inount d in its bearings 03g to rotate freely. The chuck G81 carries the square winding mandrel 62 in a detachable manner. rl`his chuck is on a shaft 63C extending through the hub of the sprocket wheel 03. n., rubber or leather friction ring 63d is interposed between the face of the sprocket wheel 03 and chuck G3i and the latter is pressed into frictional contact with it b y the spring 63 surrounding its shaft 63@ and acting upon a nut @3f which may be adjusted to vary the driving tension between the sprocket wheel 03 and chuck 03h. For nar row webs 5S less tension is reqtiired than for wide webs, the width of the webs being changed to suit the width of the dies from which the printing is to be donc. A. pawl 63h acts upon the toothed periphery of the chuck to prevent it being rotated by any pull upon the web which would tend to unwind the mandrel 62. The cause of such backward pull is the friction upon the web at the time the die is being wiped by the wiper.
1While l have shown the clutch 87 as applied to the shaft 82 it is evident that it may be applied anywhere between the driving pulley and the cam shaft 21, and as this forms no part of my invention itwill not be necessary to describe it in detail. lt will suffice to say that, as in numeroustypes of machines, it is designed to be able to stop the machine after each impression if so desired.
.ris practically all of the operative mechanism of the press receives power from the cani shaft. 21", it is. only necessary to d'islenu said cam shaft through the driving shaft 64.- to stop the operation of the printing mechanism. This is accomplished by means of the clutch 8T which may be of any suitable construction and siifted by a lever S7 arranged on the side of the machine.
Vlhile lf have shown the details of con struction which l have preferred and employed in the commercial forni of press embodying my improvements, do not confine myself to these specific details, as it is eviw dent to one skilled in the art that the same general adjustments may. be accomplished by other forms of the said details without departing from `the spirit of the invention involved in them.
