SPECIFICATION forming part of Letters Patent No. 634,658, dated October 10, 1899.

7 Application filed December 8, 1898- Serial No. 698,622. (No model.)

To all] whom it may concern:

Be itknown that I, CHARLES E. BRINKL WORTH, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in 'Piate-Printing and Embossing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which forma part of this specification.

My invention relates toimprovements in plate-printing and embossing machines, its

object being to simplify the construction of parts, concentrate the same, and increase their effectiveness. 7

Referring to the drawings, 1 is the powershaft, journaled in an arm 2 on the front por- Fig. 6 is an enlarged detailfront view of the revolving ink-removing 'tion 3 of the main frame. Upon the powershaft 1 is rigidly mounted the large handwheel 4 for turning the same, although my improved machine can be operated by any other than hand-power, if desired.

' 5 is a small gear-wheel rigidly mounted on the power-shaft 1 and intermeshin g with the large gearwheel 6, which is rigidly mounted on the rear end'of shaft 7, (see Fig. 2,) which is journaled in bearings in the front portion 3 and rear portion 8 of the main frame. Upon the front projecting end of this shaft? is rigidly mounted the wheel 9 for carrying the impression-bed, which consists'of the metal socket 10 in removable dovetailed engagement with the periphery of the wheel and the flexible bed 11 seated thereon. The bed 11 may be of felt or any'other analogous material which will produce the proper impression.

12 is another shaft journaled in the front andrear portions 3-and 8 of the main frame and above the shaft 7 Upon the rear projecting end of this shaft 7 is rigidly mounted shaft 16, upon which is rigidly mounted the gearrwheel 17 of equaldiameter with the gearwheel 14 and intermeshingwith the same. Upon the shaft 12and in front of the gearwheel 1 is rigidly mounted the plate or die carrier 18, which consists of a curved arm, as shown, to facilitate the adjustment thereon of the plate or die.

19 is a screw-threaded shank adjustable in a radial socket in the outer end of the curved arm 18 by means of the nuts 20 20. The outer end of the shank 19 has the attached block 21, to the outer face of which is removably and adjustably secured the printing plate or die 22, in which are cut or engraved the inscriptions to be printed or embossed;

The means which I employ to secure the printing-plate 22 upon its block 21 consists of the plate 23, having its,ends 24 turned up at right angles thereto, so as to lie close againstthe ends of the block 21 and be adj ustably so:

cured thereon by the screws in the slots 26, which have open ends to facilitate the removal of the printing plate or die 22.

The means which I employ to ink the engraved plate or die are arranged as follows:

27 is an arm see Fi 5 which is ri idly seadjusted by means of the nut 35, which is locked in its predetermined position by the nut 36. A spiral spring 37, interposed between the socket 29 and a nut 38, permits the inkingpad to yield slightly under pressure. The pad 32 receivesits ink by passing contact with the roller 39, which is caused to revolve in an open receptacle 40, suspended from the arm 15 of the main frame and containingink,through which the roller 39 passes. This roller is caused to revolve in the same direction to that of the inking-pad by the crossed belt 41, which passes around a pulley 42, (shown in dotted lines,) rigid with the roller 39, and a pulley 43, rigid on the shaft 16.

The means which I employ for first removing a large portion of the surplus ink deposited on the printing plate or die 22 by the inking-pad 32, thus preparing it for a much more thorough action of the wiping-strip, are as follows: 44 is a brush having its shank 45 (see Fig. 6) journaled in a socket 46 at the outer end of an arm 47, (see Fig. 7,) secured to an open extension 48 of the frame and of such a length as to bring the brush 44 in line with the rotating printing plate or die. Rigid with the shank 45 of the brush 44 is the pulley 49. Two pulleys 50 50 are rigidly mounted on the shaft 51, journaled on opposite sides of the open frame 48 and at right angles to the revolving shank 45 of the brush 44. A belt 52 passes around the front of pulley 49, then down around the rear sides of the pulleys 50 50, and around a pulley 53 (shown in dotted lines) on the shaft 12, by means of which a rotary motion is given to the brush 44. In Fig. 6 is also shown in detail the means for properly alining the shaft 12 to insure an even impression of the printing plate or die 22. The journals each consist of the separate sections 54 and 55 in removable engagement with each other, the upper section 54 being in screw-threaded engagement with the adjusting-bolt 56, which is raised or lowered in a screw-threaded socket in the plate 57, the bolt being turned by the pin 58 in its upper end.

The pressure-pad for effecting the cleaning of the printing plate or die by means of the insure its perfect register.

wiping-strip before the impression is taken is constructed and arranged for operation as follows: 59 isa lever pivoted near its center, as at 60, to the vertical arm 61 of the main frame. Its outer arm 62 is provided with the adjustable counterweight '63, and its inner arm 64 has its outer end (35 bent upwardly at an angle to make it practically parallel to a tangent of the circle which the printing plate or die describes atthe point of contact of the wipingstrip with the printing plate or die. Upon this outer end 65 of the arm 64 of the pivoted lever is adjust-ably secured the pressurepad (56, preferably of felt, held in position by the tightening-belt 67, working through the carrying-frame 68 against the upper side of the arm 65. The operative surface 69 of the pressure-pad 6G is curved in a circle concentric to the circle described by the printing plate or die and is preferably covered by a strip 70 of a material with a slightly-roughened surface. To bring the pressurepad down toward the passing printing plate or die 22 for the cleaning operation,I have provided the rigid arm 71, secured to one side of the outer end 05 of the lever-arm 64. The lower end of the arm 71 is turned inwardly and rides against the inner surface 72 of the rim 73 of the gear-wheel 14. Upon the surface 72 of the rim is the inwardly-projecting portion 74, (see Fig. 9,) having the long curved concentric central portion 7 5 and the inclined ends 76 and 77, theoperation of which, in connection with the arm 71, will be fully explained hereinafter.

78 is a wiping-strip, preferably of tough paper, which is interposed between the pressure-pad 66 and the printing plate or die 22 to receive upon its lower surface the surplus ink wiped from the printing plate or die. This strip 78 is intermittently fed from a roll 79, mounted on the arm 80 of the frame at its right-hand side. It passes between two feeding-drums at the right-hand end of the frame, the upper one of which is shown at 81. The lower drum is behind the ratchet-wheel 82, which operates in conjunction with the spring-pawl 83 on the carrying-frame 84, in which the drums are mounted. To the axle 85 of the lower drum is secured the slotted arm 86 in adjustable engagement with the pitman-rod 87, the inner end of which is secured to the outer revolving end of the crankarm 88, rigidly mounted on the shaft 12.

I have provided my improved machine with an automatic device for holding the sheet in fixed position, so that when the printing plate or die and the impression-bed meet the interposed sheet in passing contact it will prevent the accidental displacement of the sheet and This device is constructed and arranged as follows: A lever is pivoted at 89 to the depending arm 90 of the frame and consists of the lower short arm 91 and the upper long arm 92, which has pivotally secured to it at the point 93 the pitman-rod 94, the curved end 95 of which. is in looseengagement with the eccentric cam 96, rigidly mounted on the 'shaft12. To the lower short end '9l of the lever is rigidly secured .the spring-arm 97 at practically right angles My improved machine, which I have just describedindtail, operates as follows Power being applied, the wheel 9, carrying the impression bed 1O 11 hasimparted to it a positive rotation, while the gear-wheel 14 and plate or die carrier have an opposite or nega tive rotation imparted thereto. The impression-bed and printing plate or die are so adjusted as to meet in bearing contact through the opening in the table 100. card to be printed upon or embossed is placed across the opening 101, so as to receive the impression therethrough, itbeing held at the proper instant by the spring-pad 98, which prevents it from being accidentally thrown out of register as the printing and impression-bed swing together in bearing contact; As the shaft 12 continues to revolve, its attached eccentric cam throws the pitman 94 over to the left, carrying with it the long upper arm 92 of the pivoted lever, which causes its short lower arm 91 to be thrown to the left. This has the effect of raising the spring-pad 98 from bearing contact with the sheet immediately after the impression is made, so that it canbe removed and the next sheet placed in position to be held by the again descending pad 98, as before. The gearwheel 14 imparts to the intermeshing gearwheel17 a motion of positive rotation, which causes the inking-pad 32 to swing up into passing contact with the rotating printing plate or-die 22 and ink the same, the pad 32 having received upon its surface a quantity of ink by its passing contact with the inkroller 39, revolving in the same direction. As the now inked printing plate or die 22'continues its further rotarymotion, it comes in passing contact with the revolving brush 44, which as the plate or die is passing removes a large proportion of the superfluous ink and prepares the plate or die for the effective action of the pressure-pad 66, which it next meets in passing contact. Just before such contact the revolving crank-arm 88 has pulled the pitman 87 over to the left, which carries with it the slotted arm 86, which in turn operates the feeding-drums and interposed wiping-strip 78 to present to the action of the pressure-pad a clean portion of such wiping As the gear-wheel lat rotates in strip.

' son with the pr nting 'jecting portion '74 The sheet or plate or die diminary cleaning of the plate or die--that is, in negative rotation, as indicated by the arrow in-Fig. 9the turned-in end of the rigid arm 71 strikes the inclined end 7 (l of the proand serves to abruptly pull the pressn re-pad (carried on the pivotedlever) down in bearingcon tact with the printing: plate or die which has now reached this point. As the rigid arni 71 rides along the concentric portion75, it preserves an effective bearing contact of the pressure-pad against the interposed wiping-strip 78 during the entire contact of the printing plate or die. This arm 71 reaches the inclined end '77 of the projectingportion 74 just as the printing plate'or die is passing away from contact withthe pressure-pad, and as it rides down such'in- V clined" end 77 it releasesthe pressure-pad 66,

which islthen thrown upwardly by the action of the counterweight 63, ready for the next succeeding operation. This wiping action just described effectively removes from the face of the printing plate 'ordie all of the ink except that'whieh fills the engraved or out lines thereon, next succeeding printing or embossing in the manner already described. The operation of my improved machine as just described en-- ables me to print or emboss in a rapid, accurate, and reliable manner. The proper impression can be quickly and accurately adjusted, andthe improved means which I employ for cleaning the surface of the printing "plate or die enables me to thoroughly remove all the superfluous ink, and thereby preserve the printed or embossed sheet or card free and clean of all blemishes. The action of the revolving brush 41L renders the wiping action much more complete than it would he were the revolving brush omitted. Then, too, the novel series of actions of the pressure-pad due a to the rigid rod Tl-viz. first, the abrupt contact; second, the uniform wiping contact, and, last," the abrupt release from contact serve tdmake the wiping action as perfect and effective as is possible in a mechanical manner. a

The devices which I employ to perform the cycle of operations from one printing or embossing to another-viz., the inking, the preprinting-plate, the final wiping of such plate, and then the printing or embossing-are all arranged in a compact form are exceedingly easyand simple of adjustment, and perform the work of printing or embossing fromv engraved plates or dies in a perfect manner.
