HENRY F. BECHMAN, OF BATTIJE CREEK, IHICHIGAN, ASSIGNOR TO THE DUPLEX PRINTING PRESS COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 569,081, dated october e, 1896. Application filed Aprn 20,1896. serial No. 588,215. '(No model.)

To all whom it may concern,.-

Be it known that I, HENRY F. BECHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Printing- Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompaside means that side of press on which are nying drawings, and to the letters of reference marked thereon, which form part of this specieation.

This invention is an improvement in stationary-bed and locomotive-cylinder sheetprint-ing perfecting-presses of the type disclosed in my application for patent, Serial No. 567,020, led October 26, 1895.

The objects of this invention are, first, to simplify the sheet-transferring devices by substituting for transferreels vibratory sheet-carriers; second, t-o obviate the reciprocation of either bed; third, to improve the sheet-delivery mechanism; fourth, to provide improved and novel gripper-actuating devices; finally, fifth, to improve the press in various other details, all of which objects I accomplish by the means hereinafter described, and which are illustrated in the accompanying drawings, forming part of this application.

Referring to the drawings, Figures 1 and 1b representV longitudinal side elevation and section of the complete press, the drive-side frame being removed and the beds broken awa-y to shorten the iigures. Fig. 2 is a vertical transverse section through the press slightly enlarged on line 2 2, Fig. 1a. Fig.Y 3 is an enlarged side View of the sheet holding and transfer mechanism. Figs. et, 5, and G are longitudinal sectional diagrams of the press, showing the variousvtransfersof sheets passing through the press. Fig. 7 is a side elevation of the complete press. Fig. 8 is a detail vertical transverse section through the crank-wheels and side frames. Fig. 9 is an enlarged detail view of the upper cylinder and the mechanism for operating the stripping-fingers L2. Fig. 10 is a detail end view of cylinder B, showing the gripper-operating devices. Fig. 11 is a vertical section through Fig. 10. Fig. 12 is a detail view of the driving mechanism for shaft K. Fig. 13

` respectively. view of the gripper-tripping Vdevices of the is a detail plan View of lthe sheet-delivery tapes and carriers on the frame and carriage, Fig.' 14 is a detail sectional vibrating sheet-transfer mechanism. Figs. 15 and 16 are detail Views of parts D4 and O6 detached. Fig. 17 is a detail view of lever O8.

In the following description the drive located the driving pulleys and shaft, .the op- .posite side being referred to as plain side.

Crank or rear end means the end where the largecrank-wheels for driving the cylinder-carriage are located, and the other end of press is designated as front end.

A A are the type-beds, secured rigidly between the side frames of the press and preferably arranged horizontal and parallel, one

directly o ver the other.

B B are gripper impression cylinders adapted-to operate on beds A A', respectively, journaled in a reciprocating carriage formed o f sliding cross-heads C, which are supported and guided on the side frames and are moved horizontally back and forth to travel the cylinders back and forth over the beds bymeans of pitmen C', connected to crank-wheels C2 C4 on the main drive-shaft C3 at the crank end of press, the cross-heads, pitmen, and crank-wheels being exterior to the side frames, as shown. On one end of the upper cylinder B' is fixed a gear b, which meshes with a stationary cylinder-rack b', as usual. On the corresponding end of cylinder B is agear b2, which meshes with a cylinder-rack b4, which is slidably mounted on the side frame and is shifted endwise at the proper times by means of a connecting-rod b5, crank-lever h6, and cam bT on crank-wheel C2, as shown. The object of this is to give an additional amount of rotation to the cylinder B, as hereinafter explained.

The lower cylinder B is provided with two sets of oppositely-disposed grippiiig-ngers D cl, mounted on transverse shafts D d', on

the ends of which are the T-heads. D2 d2, which are connected by links D4 d4 to arms D5 d5 on the ends of shafts D6 (Z6 Within the cylinder, on which shafts are springs D7, that tend to rotate the shafts in one direction, and

Ioo

thereby will hold the gripper-fingers open or closed, according as they are shifted by the movement of the T-heads. On the shaft of cylinder B, just opposite the T-heads, is a loose gear E, to whichare secured tumblingpins E' E2, respectively adapted to engage T- heads cl2 D2, as indicated in the drawings. Gear E meshes with a movable rack e on the side frame beside the inking-roller rack and is moved at the proper times by means of a rod e', connected to cam-lever e2 and a cam e2 on crank-wheel C4. (See Figs. 2 and S.) The Lipper cylinder B' is also provided with two adjoining but opposite sets of gripperfingers F f, mounted on shafts F' j', provided at one end with T-heads F2 f2. Said shafts maybe controlled by spring mechanism like the grippers on cylinder B, or in other suitable manner. On the end of the shaft of cylinder B', opposite T-heads F2 f2, is a loose gear G, to which are attached tumbling-pins G' G2, respectively adapted to engage T- heads F2 f2, as indicated in the drawings. The grippers on the upper and lower cylinders are actuated and operated substantially as described in my application aforesaid. Gear Gr meshes with a movable rack g, which is shifted at proper times by means of a connecting-rod g', cam-lever g2, and cam g3 on shaft C3.

The operation of the gripper mechanism is hereinafter described.

At each side of each impression-cylinder is a setI of distributing and form-inking rollers suitablyjournaled in the cross-heads and reciprocated therewith back and forth over the beds, ink being supplied thereto from stationary fountains I', as shown.

At each-side of the upper impression-cylinder and traveling therewith is a pair of parallel shafts J J and j j', respectively, which are journaled in the cross-heads above the inking-rollers I, and upon which are mounted tape-pulleys, as shown. Beside shaft J' is a shaft J2, also journaled in the cross-heads C and carrying a series of radial, horizontallydisposed arms J3, upon each of which arms are mounted tape-pulleys J4 J5, the latter (outermost) of which may be adjustable to enable the tapes J 6, which run thereover, to be tensioned. Beside shaft ,7" is a shaft J2, also journaled in the cross-heads and carrying a series of horizontal arms 92, on each of which are mounted tape-pulleys j4 said tape-wheels supporting tapes j, as shown.

Bevel-gears J S and js are fixed on the outer ends of shafts J j and mesh with bevel-gears K' on a rotatable shaft K, which is journaled in bearings K2, attached to the cross-heads, and in a bearing K2,attached to the side frame, and splined on the rear end of shaft K, beside journal K2, is a bevel-gear K4, meshing with a bevel-gear 7s, mounted on a stub-shaft k', journaled in the side frame, which stubshaft is driven by a train of gears k2 k2 from the feed roll or cylinder T, hereinafter referred to. By this construction the shafts J j are (during the operation of the press) continuously rotated in one direction,so as to cause the upper parts of tapes J 6 j to travel away from the cylinder B'. Obviously the shaft K has a reciprocating as well as rotary motion.

On shafts J j' are mounted stripping-fingers L, which are caused to raise and lower alternately at the proper times by means of crank-arms L2 on the ends of shafts ,7" J, having rollers L3 on their ends, which bear upon the periphery of one of the bearers of cylinders B' and enter cam-grooves L' in the bearer at the moment it is necessary to lower fingers L. (See Fig. 9.)

Overlying each set of tapes J G j is a board l, attached to the cross-heads, as shown.

At points beyond the limits of travel of cylinder B and in about the same plane as shafts J' j' shafts M m are mounted on the main frame, said shafts carrying arms M' m', having tape-wheels M2 m2, over which run endless tapes m2 M3, which are adapted to lead sheets back to the folding mechanism located at each end of press. Vheels M2 on arms M' are so arranged as to pass by and between wheels J 5 on arms J 4, so that a sheet of paper coming from the impression-cylinder on tapes J 6 passes onto tapes M2 and is delivered thereby into the folding mechanism, as indicated in the drawings, which, however, needs no description herein. Wheels m2 on arms m' are adapted to similarly coact with tapes j,

The sheets are transferred from cylinder B to cylinder B' at each end of the press by the following means: At each end of bed A' is a vibrating or swinging sheet transferring mechanism. The rear transferring mechanism consists of two or more arms N, which are roughly triangular and pivoted at one corner to brackets A2 on the rear end of bed A', as shown. These arms N are connected by transverse bars N N2, to which bars are attached a series of curved fingers N3, which bend approximately on the arc of a circle having the pivots of the arms as its center. One arm N is connected by a link N4 to a sliding bar N 5, which is reciprocated at the proper time by a pitman N6, connected to a crank-arm N on a stub-shaft N8, journaled in the side frame on the drive side of press, said stub-shaft being driven by gears N9 N10 from shaft C3. In the arms N, adjoining and parallel with bar N is a gripper-shaft O, carrying fingers O', and on one end of shaft O is a crank O2, to which is connectedv one end of a rod O3, the upper end of which has a boss O4, which engages a slot O5 in a plate O6, attached to the hub of the adjoining arm N, and which boss also engages a slot O7 in one end of a bell-crank lever 08, pivoted to the side frame and vibrated by means of pitman O9, connecting it with a cam-lever O10, engaging a cam O11 on shaft N8. These devices are adapted to open the gripper-fingers O' at the proper times, the fingers being closed by springs O19 on shaft O. At the opposite end IOC IIO

of bed A' is a duplicate sheet-transferring mechanism, which is in every way identical with that already described. The parts of this second transferring device,'lettered n n' n2 a5 n4 o o' o2 o3 o4 o5 o6 o7 o8 o9 010, correspond in construction, arrangement, and mode of operation with corresponding parts lettered N, N', N2, N2, N4, O, O', O2, O3, O4, O5, O5, O7, O5, O9, and O10, above described, and detailed description of the front transferring mechanism is therefore unnecessary. The cam-lever 040, however, is actuated by a cam O12 on a shaft O12, driven by gears O54 from the cutting-roll t. Further, the forward set of transferring devices are reverse to the rear set, and as arms II rise arms/n descend, and vice versa, as indicated in the drawings.

The transfer-arms N n do not deliver the sheets directly to the upper cylinder, but to superimposed sheet-holders arranged as follows:

I will describe the rear sheet-holder first. P P designate hangers pivoted to cranks P', attached to a transverse shaft P2, journaled in brackets P5, adjustably attached to upper extensions of the side frames, as shown, and provided with adjustable stop-bolts P4 P5 for regulating and arresting the vibrations of arms P when shaft P2 is rocked (at the proper times) by a pitman Q, connected to a crank Q' on the outer end of shaft P2, which pitman connects with a cam-lever Q2, pivoted on the plain side of press and operated bya cam Q3 on a stub-shaft Q4, driven by gears Q5 from shaft C2, as shown. When the shaft P2 is rocked, hangers P are raised or lowered, as indicated in Fig. 3.

On the inner sides and lower parts of hangers P are ribs P6, which. engage a pivoted guide P7, having a pivot PS, journaled in the side of casting P5, as shown in Fig. 2, so that when the hangers are raised and lowered they will also be oscillated and guided to move accurately. On the lower ends of hangers P is a transverse gripper-bar R, beside which is a gripper-shaft R', carrying ngers R2, adapted to be closed against the bar by means of springs R3 on shaft R', or otherwise suitably arranged. On shaft R' is a short arm R4, having a roller R5 on its end, which is adapted to be engaged by the inclined lower end of a trip-lever S, depending from a horizontal rod S', journaled in hangers P. The trip-levers can be drawn backward, so as to force down arm R4 and cause it to rock shaft R' and open fingers R2 by means of a slide S2, mounted in a guide-casting S5, attached to casting P2, said slide projecting past the trip-lever and having a roller S4 on its inner end, which engages the lever when the slide is drawn backward. The slide S2 can be reciprocated by means of a connecting-rod S5, attached to a pivoted lever S15, having a roller Si on its lower end engaging a cam ST on shaft Q4.

The front sheet-holder consists of parts arranged, constructed, and operated like those of the rear sheet-holder. The parts p p' p2 Pspfipspsprps q ql Q2 Q37. 7.17.2 7^3.475 7.6 SSI s2 s2 s4 S5 S5 S5 of the front holder correspond with parts P P' P2 P2 P4 P5 P6 P7 P8 Q Q' Q2 Q3 R R' R2 R2 R4 R5 RGSS S2 S3 S4 S5 S6 S5of the rear sheet-holder, and further description thereof is unnecessary. The cam q2 is mounted on the outer end of a stub-shaft Q7, journaledV in the plain side frame and driven by gears g8 Q9 from the cutting-cylinder t', as indicated in the drawings, and the cam S5 is also mounted on shaft g5. The front sheetholder, however, is reverse to the rear sheetholder to operate properly in conjunction with the front sheet-transfer mechanism.

In the press shown the lower cylinder is fed with sheets at each end of its travel, which sheets are supplied from a web. At the rear end of press the web W is led to two cutting-cylinders T T',between the main shaft C5 and the beds, the female cutting-cylinder T being driven by a train of gears N9 Z541@ from shaft C2. (Indicated in dotted lines, Fig. 7.) This cylinder also serves as a feedcylinder, a set of feed-tapes T3 and suitable tape-rollers T4 being employed in connection therewith. From the cylinders T T' the web W' or sheet passes between tapes T5 and guides TG, arranged as shown in the drawings, onto adjustable fingers T9, whereby its edge is presented in position to be caught by the grippers d on cylinder B when the latter is at the end of its rearward travel. At the front end of the press the web is led to a pair of similar cylinders t', feed-tapes t2, and presenting tapes and guides t5 t6 to fingers t, by which the sheets are presented in .position to be caught by fingers D on cylinder B When it is at the front end of its travel. The cylinders T T' and t t' are intergeared, and cylinder t' may be driven from cylinder T' by means of a bevel-gear T9 on the end of cylinder T', meshing with a bevel-gear T7 on a horizontal shaft T8, which is jonrnaled on the driving side of the frame and extends back through the boss of the cross-head (see Figs. l and 7 to the rear cutting-cylinder, a bevelgear t7 on shaft T8 meshing with a bevel-gear t2 on cylinder t', driving the latter. By this means the action of the feed mechanism at both ends of press is made synchronous.

However, I do not confine myself to the particular means for imparting movement to the parts herein shown and described,

Operation The cutting-cylinders are geared v so as to make one revolution to one revolution of main crank-shaft C3. Shaft N8 revolves once for each revolution of the main shaft C2, thereby shifting bar N5 horizontally and causing the front and rear sheet-transferring devices to rise and fall, and fall and rise, respectively.

For simplicity of explanation I will trace the passage of one sheet through the press, indicating its position at various stages by letters. Supposing the parts to be in the position shown in Fig. la, where the cylinders IOO IIO

are at or about the rear end of their stroke. As cylinder B starts forward grippers CZ take a sheet from the fingers T9, and it is printed on one side from the forms on bed A before the cylinders reach the forward end of their stroke. 'At the forward end of their stroke fingers d on cylinder B release the sheet and the grippers on front transferarms n close thereupon. Vhile the cylinders move backward, arms n lift the printed sheet up, and, as the cylinders reach the end of their back stroke, surrender the sheet to the front sheet-holders p. During the next forward stroke of the cylinders the front boardl passes beneath the sheet hanging from holders p, and said sheet is laid upon the board Z smoothly and evenly, and while the cylinders are at the forward end of their stroke the holders p are lowered to the position shown in dotted lines, Fig. 3, and the sheet surrendered to the grippers F of cylinder B. Then at the next backward stroke of the cylinders the sheet is printed and perfected upon the forms on bed A', and before the cylinders reach the rear end of stroke the sheet is partly delivered onto the tapes J6. This operation is alike foreach sheet taken from iingers T", and the same operations are performed by the cylinders, transfer-arms N, holder n, board Z, and tapes j for each sheet taken from fingers t9.

Briefly the function of each mechanism is as follows: The holders p take 4a sheet of paper from the front transfer-arms n when the impression-cylinders are at crank end of stroke and transfer-arms n are at their highest position and transfer the sheet to upper cylinder B when it is at front end of stroke. The holders P take the sheet of paper from the rear transfer-arms N when the impression-cylinders are at front end of stroke and arms N are at their highest position and afterward delivers the sheet to upper impression-cylinder B when it is at the rear end of stroke. Rear transfer-arms N take a sheet of paper from lower impression-cylinder B when it is at crank end of stroke and deliver it to holders P when impression-cylinders are at front end of stroke. Front transfer-arms n take a sheet of paper from impressioncylinder B when it is at front end of stroke and transfer the sheet to holders p when impression-cylinders are at rear end of stroke. Both impression-cylinders B B travel the same distance, and both would therefore naturally rotate the same amount; but a proper rotation for the upper impression-cylinder is not enough for the lower impressioncylinder, as the grippers on lower impressioncylinder carrying a sheet must be advanced farther to deliver said sheet to the transferarms. This extra rotation of cylinder Bl is accomplished by the sliding rack b4, above derotated back to its position proper for printing after having delivered one sheet and taken on a new one. From the roll of paper at the crank end of press the WebWV is led over the idler-roll W', around the female cutting-cylinderT, thence between the cutting-cylinders T and T', whereby a sheet of paper is partially (only three or four narrow strips of paper holding it) severed from the web. The partially-severed sheet is then carried down by the carrier-tapes T5 (which run slightly faster than the web, so as to keep the sheet straight and smooth) to the lower impressioncylinder B. The gripper d (shown closed in Fig. 1) then closes on the incoming sheet and firmly holds it, and as the impression-cylinder B starts on the forward stroke the remaining narrow strips of paper, which hold the sheet to the web, vare broken and the sheet is carried around by the impressioncylinder, passing over the type, where one side of the paper is printed. Impression-cylinder D upon arriving at the forward end of its stroke transfers the sheet just printed to transfer-arms n, which are at their lowest position, as previously explained. This transfer of sheet is effected by the cylinder-grippers d opening and the transfer-arm grippers ol closing on said sheet, as hereinbefore described. Lower impression-cylinder B then starts upon its backward stroke, its opposite grippers D closing upon a sheet of paper at feeding-fingers t at front end of press, and during the back stroke of cylinders transferarms n rise to their upper position, as shown in Fig. l. In this position the transfer-arms n surrender the sheet of paper to the holders p, and at the same time impression-cylinder B is transferring the sheet of paper taken from the web at the front end of the press to transfer-arms N.

Once more the impression-cylinders B and B' travel to the forward end of their stroke. Thus the following operations occur: First, the sheet of paper held by holders p is transferred to upper impression-cylinder B; second, the sheet of paper held by transfer-arms N is surrendered to holders P, and, third, the sheet of paper held by lower impression-cylinder B is surrendered to transfer-arms fn. An instant later, when lower impression-cylinder B has started on its backward stroke, a new sheet is taken by it from feed-fingers 9 at front end of press, it being understood that the lower impression-cylinder takes a sheet of paper from opposite ends of the press at every revolution of crank-wheels, thereby securing a printed sheet every time the impression-cylinder passes over the type.

Then the impression-cylinders are on their backward travel about the middle of the stroke, and at a time when the advanced edge of the sheet being printed upon the upper irnpression-cylinder B is just above stripping- ICO IIO

fingers L, grippers F open and the sheet is switched out upon delivery-tapes J 6. Then when impression-cylinders are again at crank end of stroke, the following transfers take place: First, the sheet of paper on deliverytapes J6 is transferred to folder-tapes M3 second, the sheet of paper held by holder P is surrendered to cylinder B'; third, the sheet of paper held by transfer-arms n is transferred to upper holder p, and, fourth, the sheet of paper on lower impression-cylinder B is surrendered to transfer-arms N. On the next forward stroke of impression-cylinders the same takes place, the sheet on upper impression-cylinder B being delivered to front folder-tapes ll 3 and transfers of all other sheets in the press taking place, as previously described.

I do not limit myself to the employment of the vibratin g sheet-transfers with the particular construction or arrangement of printing mechanisms herein shown, for obviously, for instance, the transfer mechanism would be useful in a press wherein the beds and cylinders were both reciprocated, and therefore I refer to the following claims for the definitions and limitations of my invention and the novel and useful parts and combinations of parts involved therein and useful in printing-machines.

I would remark that grippers on top impression-cylinder are not open, as shown in Figs. 4 and 6, except when taking or delivering sheet of paper, and it is not necessary, nor do I contemplate, having the grippers of cylinder B tumble entirely over, but just open enough to take or deliver sheets. Indeed, practically no grippers on press tumble entirely over, except those on lower impression-cylinder, but in the diagrams especially I have shown the grippers tumbled fully for sake of clearness.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

25. The combination of the stationary bed and reciprocating cylinder, having a grippershaft, the shafts J, J beside the cylinder and traveling therewith, the shaft J2 carrying arms J2, tape-wheels J5 on said arms, and tapes J 6 arranged substantially as described; with the stripping-fingers L on'shaft J", and means for oscillating said shaft, so as to cause the fingers to strip the sheets from the cylinder into the tapes during the travel of the cylinder, the delivery-tapes, and the arms M' for the purpose and substantially as described.

26. The combination with the stationary bed, and reciprocating cylinder,`the shafts J, and J2 beside and traveling with the cylinder, the arms J2 on shaft J2 carrying tapewheels J 4, and the tapes J 6 arranged substantially as described; and means for driving the tapes in one direction; with the stationary shaft M, carrying arms l\ with rollers M2, and the tapes M2, substantially as described, adapted to receive the sheets from tapes J6 when the cylinder is at the end of its stroke, all substantially as described.

27. The combination with the cylinder B having gripper-shafts,provided with T-heads, D2, cl2, the spring-controlled shafts D6, d, having arms D5, d5, and the links D4, d4 connect- IOO IIO

ing said arms to the T-heads, with the loose gear E carrying pins E E2 respectively adapted to engage said T-heads, and means for regulating the rotation of said gear, independent of its travel with the cylinder, all substantially as and for the purpose set forth.

28. In a printing-press the combination of a type-bed, a reciprocating gripper-cylinder, a device adapted to temporarily suspend the sheets substantially as described; and means for transferring printed sheets from the cylinder to the holder, and mechanism for removing the'sheets from the holder, substantially as and for the purpose described.

29. In a printing-press the combination of a type-bed, a reciprocating gripper-cylinder, and a sheet-holder above the bed; With a vibrating sheet-transferring mechanism adapted to take printed sheets from the cylinder and deliver them to the sheet-holder; and mechanism for removing the sheet from the holder, substantially as and for the purpose described.

30. The combination of a stationary bed and reciprocating gripper-cylinder; with Vibrating sheet-transferring arms at each end of the bed, adapted to take printed sheets from the cylinder; means for simultaneously vibrating said transfer-arms, in opposite directions; and means for removing the sheets from the said arms, substantially as and for the purpose set forth.

3l. In a printing-press the combination of a type-bed; a reciprocating cylinder; sheetdelivery tapes mounted on the cylinder-carriage, and adapted to receive the sheets from the cylinder; and means for driving said tapes; a fixed set of tapes beyond the range of travel of the cylinder, but projecting into the path of travel of the moving tapes, so as to alternate therewith when the cylinder is at the end of its stroke, whereby the printed sheets are transferred from the cylinder-tapes to the fixed tapes While the cylinder is at the end of its stroke, substantially as described.

32. In a printing-press the combination of a type-bed; a reciprocating cylinder; sheetdelivery tapes mounted on the cylinder-carriage, and adapted to receive the sheets from the cylinder; stripping-fingers also moving with the cylinder adapted to direct the sheets onto the tapes; and means for drivingsaid tapes; a fixed set of tapes beyond the range of travel of the cylinder, but projecting into the path of travel of the moving tapes so as to alternate therewith when the cylinder is at the end of its stroke, whereby the printed sheets are transferred from the cylinder-tapes to the iXed tapes While the cylinder is at the end of its stroke, substantially as described.
