POWER PRINTING-PRESS.

Specification of Letters Patent No. 24,357, dated June '7, 1859'.

To all whom it may concern:

Be it known vthat I, JEDEDIAH MORSE, of Canton, county of Norfolk, and State of Massachusetts, have invented an Improved Power Printing-Press; and I do hereby declare t-hat the same is fully described and represented in the following specification and t-he accompanying drawings, of which- Figure l, is a top view of the said press; Fig. 2, a front side elevation of it or an ele-y vation of that Side on which the fly-wheel is situated. Fig. 3, is an elevation of its opposite side. Fig. A, a vertical and `'transverse section, such being taken through the platen and bed. F ig. 5, is a longitudinal, central and vertical section. Fig. 6, is an elevation of that end at which the pile platform isA situated, such being termed the rear end. Fig. 7, a front end elevation.

Such other figures as may be necessary to a correct delineation of my improvements` will be hereinafter described.

rlhe nature of my invention or improvements may be considered to consist in the following-that is tosay: In a peculiar construction of the platen rails or those on which the platen is supported while being moved from over the movable bed, the same consisting in constructing each of said rails with an inclined chute or rise and a. depression, the purpose of the chute being not only to steer the platen clear of the sheet discharging rollers, but to form a rest for the lower or movable portion of the inclined feeding table; the depressions of the rails being to receive the rearmost wheels of the platen so as to hold the platen back or away from over the bed. Also, in an arrangement and combination of a slider with the operating cam of, and the pin or stud projecting from one of the rocker toggles of the bed, the purpose of such slider' being` to prevent an impression being given by the bed. Also, in the peculiar device or mechanism for gradually moving forward or to places the rocker toggles during falling of the bed. Also, in a combination of wheels,lever nippers, and devices for Operating or opening and closing the 'said ,nippers, the same being for receiving a printed sheet of paper from the carrying tapes, re-

' versing it, and so delivering it upon the pile table\tha,1J` theAY imprinted face of the said sheet shall be upward, in order that the imprint thereof may be easily examined.

Also, in ari'node of constructing the nippers for receiving the sheet of paper and drawing itvover the form of type.'` Also, in constructing* the lower' nipper with a raised lip on its front edge,`the saine being for elevating or bringing the paper up to the level of the type printing surface so as to enable the printing to be done close up to the nippers. Also, in a mode of applying and operating each of the sheet points. Also, in a. mode of operating' the frislet carrier or carriage.

)In the drawings above mentioned, A, ex-

hibits the press'frame; Bthe platen; C, the' movable bed; D, the frisket carriage; E, the pile platform; H, H, the arch rods, and I, the' arch bar, which supports the f platen; K, is the driving 'shaft and L, the

main cam. shaft, the two being gearedL together by gears,yM, and N, as 'shown in Fig. 5. The said driving shaft carries a fly wheel, O', and a spur gear, P, which is shown in dotted lines in Fig. 2,- Such driving shaft when the machine is in operation being rotated by power applied to it in any proper manner. The frislret carriage D, is a rectangular frame which is hinged to the inking roller frame F, at one side of it while its other side is supported by two arms a, ci, extending upward from aroeler shaft .7), arranged as shown in Figs. 2, 3, and 5. When this latter shaft is; turned or pan tially revolved in' its'bearings,Av the fri'sket carriage will ,be caused topass downward in an inclined direction underneath the carrying rollers of the endlessv tapes by which a lsheet o'fpaper after having been printed is removed from the' frisket, the loweri'nost pair of such carrying rollers and their tapes being shown at, c', c, and, d, ingFig 5. The remainder of them are omitted, as they are such as are in common use' in other presses. In such figure (5,) the frisket carriage when underneath the carrying rollers, is represented. The inking roller carriage or frame F, should be supported within or by thel frame, A, so as to be capable of moving horizontallyl therein or in a plane parallel to that of the upper surface of the platen.

G, exhibits the inclined sheet receiving table, which is arranged on vthe top of the frame, A, and with respect to; the bed and platen as shown in the drawings. It is formed in two halves or parts, e, f, which are connected together by hinges, g, g, so that the inner part, f, may be turned or" folded over upon the outer part, e, such being for the purpose. of enabling the platen, B, to be moved from over.the bed or into position as shown in Fig. 8, which also exhibits the lower half or'portion, f, of the table, G, as turned backward. The said platen is sustained by four wheels, h, h, z', z', two of which, viz, z', are furnished with radial points or teeth extending at equal distances apart from and around their peripheries as shown in the drawings. The supporting wheels of the platenV rest and run on rails, a3, a3, each of which where it extends over the bed is horizontal or has its top surface parallel with that of the bed, but between the bed and the rear part, e, of the table G, each rail a3, is constructed with a rise or chute, 7c, and a depression or notch, Z, arranged as shown in Fig. 2. Furthermore, the top surface of each rail a3, is constructed with a series of holes or cavities m, mme, arranged at equal distances asunder and for reception of the teeth ofthe wheels, h, L. The object of the said cavities and teeth are to maintain the platen parallel to the vertical plane of its arch rods, H, H, while being moved away from the same. Furthermore, each rail a3, is provided with a rise or chute k, for the purpose of enabling the platen to run clear of the sheet carrying rollers while the said platen is being lmoved awayV from the bed. The notches or depressions, t, serve to receive the rearmost wheels, z', z', and thereby prevent the platen from being moved forward or toward the bed by the action of gravity.

The movable bed, C, is operated by means of pendulous toggles-S, S, and cams, 7', r. Fig. 9, representing a section taken through the bed, oneA of the toggles and its cam, the said cams being carried by the shaft, L. Such ligure also-exhibits the slider, R, and the mechanism for operating it, the slider also being shown in Fig. 7. By means of the foot treadle lever, a, arranged as shown in the drawings, the slider may be moved inward toward the adjacent toggle, S, from the side of which a pin or stud, o, projects. The slider, R, turns on a supporting rod or fulcrum, p, so that when moved toward and upon the cam, r,- it (the slider) may be elevated by such cam. The slider and the pin, 0, serve to estop the toggles and hold them out of action of the cams, r r, when it may be desirable to throw off the impression, or in other words, to prevent the bed with the form of type from being raised upward. A spring, g, shown in dotted lines in Fig. 7, serves to move the slider, R, away from the toggle whenever the treadle lever, n, is relieved from the pressure of the pressmans foot.

As the toggles immediately after an impression has been given'by them are sometimes liable not to be properly carried forward toward the front end of the machine there is applied to them a mechanism for bringing them forward gradually as well 'as for -insurlng their return to the proper positions for their cams to act upon them. To this end the front toggle is provided with a stud t, (see Figs. 4, and 7,) which is to operate in connection with a notched wheel u, arranged as shown in Figs. t, and 7, and formed as exhibited in side view in Fig. 10. This notched wheel is aixed to the side of or makes part of a gear, Q1, which is arranged as shown in the said Figs. 4, and 7, and engages with a gear, w, carried by the shaft L. The notch a@ of the wheel u, during rotation of the wheel and while the toggles are moving forward receives the stud, t, and by its action not only insures the return of the toggles but brings them gradually into the right place for being acted upon by their cams.

The next part of my invention relates to the mechanism for operating the frisket carriage. A connecting bar or rod, y, is ointed to one of the arms, a, and also to a bell crank, z, fixed on a shaft, T, arranged as shown in the drawings. This shaft, T, carries a peculiar formed gear or pinion, a', which is to operate in connection with another peculiar gear, b, lixed upon the main cam shaft, L, (see Fig. 5,) the forms of such gears being exhibited in the said figures. These gears, a, ZJ not only impart to the frislzet carriage its back and forth movements, but also, intervals of rest, as it is necessary that the frislet carriage should be stationary while a sheet of paper is being printed as well as while the process of supplying a sheet to the frisket is being carried on. Each gear, a, and, is constructed with two arcs of teeth, c', U, and cZ, CZ and the large gear has plane convex arcs, e, e, to operate in connection with reversed or concave arcs, f', f, -of the pinion, a, the whole being formed and arranged as shown in the drawings. While a convex arc, e', and a concave arc, f, are in contact, the pinion will have no motion, although the arc,- e, may move within the arc, f, but as soon as a toothed arc of the gear, b, encounters a toothed arc of the pinion, a', it will set the pinion in motion so as to rotate its shaft and produce a movement of the frisket carriage. The intermittent motions of the frisket carriage are thus secured by the conjoint action of the said pinion, and gear so constructed.

The next part of the press to be described is the mechanism for removing the sheet of paper from the table,G, to and over the bed or form. This mechanism consists mainly in nippers applied to the frisket, D, they being exhibited at, V, V, in Fig. 1.

Fig. l1l, exhibits a vertical section and Fig. 12, a rear elevation of the frisket and its nipper apparatus, the nippers being represented therein as open. Each of them consists of two aws, f4, g4, hinged together as shown at, L. The upper jaw f4, of each pair of nippers is fastened to a shaft, i, whose journals are supported in projections or bearings, lc', 7c', extending up from the frisket, D. Each jaw, g, rests on a rod, Z, which extends from one to the other of two levers or lifters, m, m', which rest on the inking roller frame, F, and serve to support the lower jaw, g4, level, particularly while it is approaching toward the sheet table, Gr. The said lower jaw, g4, is furnished with a small bend or projecting lip, n, the same being made to extend upward in front of the adjacent or outer edge of the upper jaw, f4. The purpose of this lip has been hereinbefore mentioned.

A spring o', arranged at the back of the frisket as seen in F1g.,12, presses against arms p, p hinged to and extending downward from one side of the shaft as shown in the drawings, such spring serving to close the nippers, On the shaft, 71, being turned in its bearings so as to elevate the upper jaws of the nippers, the lower jaws of the said nippers by being supported upon the rod, Z, will at the same time be depressed or tipped downward. Thus, while the nipper jaws are being opened each will move away from the other. The opening of the nippers is effected at the proper time by the pressure of a bent arm 1"', upon a stud or projection, s, extended from the shaft, z", the said bent arm, 1", extends from a lever, s4, whose fulcrum is shown at, t', see Figs. l, and 2. Directly underneath the said lever is a bevel gear, u, which carries in rear of its range of teeth, two cams, 11, w, one of which is shown by a red line, while the other is exhibited by a blue line in Fig. 2. The outer end of the lever, 84, rests on the cam o, while that of another lever, carrying a stud, y, rests on the cam, w. A shaft, z, extends along the side .of the machine as shown in Figs. 1, and 2, and carries four bevel pinions, a2, b2, c2, and, (Z2.rr Motion is imparted to the said shaftfzfrom the driving shaft, K, whose spur gear, P, engages with another small gear, f2, carrying a bevel gear g2, which in its turn engages with a pinion, c2. Furthermore, the bevel gear, u, engages with and is rotated by the pinion, 02. That bevel pinion which is at one extremity of the shaft, z, serves to impart motion to a bevel gear, h2, which may be supposed to operate the main shaft of the ink cylinder. The lever, m', and its stud, y, actuate abent lever, 2, applied to the underside of the part, f, of the table G. The lesser or inner arm of said line 2 presses against a lever, 7a2, arranged as shown in Fig. 5, and also in Fig. 13, which exhibits a section of the said lever and the pointing apparatus connected with it and applied to the part f, of the table, G. The point or pin for pointing a sheet of paper preparatory to its being printed and while it is being laid on the table, G, is shown at, Z2, in Figs., l, 5 and 13. It extends from a foot cam, m2, constructed and arranged with respect to it and the lever, 762, as shown in the drawings. A spring, a2, serves to press the lever against the cam, such cam being provided with a locking notch or recess, 02, formed in its heel and for the reception of the adjacent arm of the lever, 7a2. This locking recess serves to enable the said lever to maintain the point in an upright position while the sheet of paper is being printed. After the printing of the sheet has taken place, and the nippers have seized the sheet, the lever, 702, by the action of the bent lever, 2, will be moved away from the point so as to allow the said point to be drawn downward into an inclined position by the sheet of paper while the said sheet is being drawn by the nippers away from the table, G. By such means the sheet will be drawn off the point and subsequently it will be elevated into an upright position by the act-ion of its lever, 762, against the cam, m2, such lever being actuated by its spring, m12. If more than one point is to be used, each additional one should have similar appliances.

The next part of the mechanism to be described is that for receiving the sheet of paper from the carrying tapes, reversing it and placing it on the pile platform, E, or a pileJ of paper thereon. At the rear end of the "machine, there is a shaft p2, (see Fig. 6,) which carries two or any other suitable number of wheels, r2, r2, see Figs. 5, and 6, and is revolved by a bevel gear, 82, that engageswith the pinion, a2, herein beforedescribed. Each of t-he wheels r2, at its circumference carries a nipper lever t2, which plays on a fulcrum, a2, and isformed with a projection, o2, extending below, the fulcrum and affixed to a zigzag or other proper spring, w2, carried by the wheel and arranged as shown in Fig. 5. The said nipper levers, t2, while the wheels are being revolved are moved successively against and by two stationary bars, m2, y2, arranged as shown in the drawings. As the sheet of paper is being delivered from the carrying tapes, it will be vreceived upon the peripheries of the wheels, r2, r2, and underneath the jaws, a2, a2, of the nippers. Now, while the said jaws, z2, are being moved forward with the sheet, they will be carried in contact with the bar, and by it will be closed down upon the sheet. In this manner, the sheet of paper becomes connected to the wheels which as they continue to revolve will carry it along with them and it will be turned over so as to bring its printed side uppermost. The sheet while being held by the wheels will fall upon the pile table or the pile of paper thereon and be discharged from the wheels; the said discharge of the sheet taking place by reason of the tail or longer arms of' the nipper leversbeing borne against the bar, y2, as they pass by the same. The nipper may be continuous stretching across, being fixed to arms on the end of the nipper shaft, or there may be separate nippers attached to arms movable on the nipper shaft or, on movable wheels as above described. Vith nipper stretching entirely across the sheet it may be received on an inclined plane and the nipper be attached at both ends to an endless band and the sheet drawn down the inclined plane under the end of the same and delivered printed side up on the table.

Having thus described my improved power printing lpress, Vwhat I claim as new therein and as my invention is as follows:

l. I claim the improvement in the construction of each of the platen rails, a3, a3, the same consisting in the chute, le, and a notch or depression, Z, arranged therein and with reference to the rollers or tapes substantially in manner andV for the purpose as herein before specified.

2. I also claim the arrangement and combination of the slider R, with the operating cam and the pin or stud O, on the rocker toggle, such slider being actuated by a foot treadle, n, a spring g, and the cam, r, of the toggle substantially as described.

3. I also claim the mode of insuring the return movement of the toggles and their gradual forward motion, after each impression has taken place, the same being accomplished by the'notched wheel, w, 0r its notch, m, as described.

4t. I also claim the mode of constructing the gears, a', and, for operating the fl'isket carrier, viz, with the toothed arcs, c, c, (l, nl', and the concave and convex arcs, c', e, and, f, f, unprovided with teeth, the whole being arranged so as to operate together substantially as specified.

5. I do not claim the subject of the United States Patent, No. 7205, but I claim the combination of two or any other suitable number of wheels, r2, r2, lever nippers t2 (applied respectively to them) and their opening and closing bars m2, y2, or mechanical equivalents for such bars, the same being substantially las and for the purpose described.

6. I also claim the above specified mode of constructing each of the nippers, V, V, for receiving the sheet of paper from the table, Gr, viz, so that each jaw may move away from the other, while the upper is being raised, the same producing the advantages not only of insuring the passage of the lower jaw underneath the sheet of paper'simultaneously with that of the other jaw over it, but of both jaws closing upon the paper at one and the same time so as not to lift it out of place.

7. I also claim the mode of constructing the lower jaw, g4, of each pair of nippers, V, viz, with a lip or bend, n, arranged thereon and for the purpose described.

8. I also claim the mode of applying and operating each of the points, Z2, viz, hinging or jointing it to the table, Gr, and combining with it a stop, m2, and lever, 71?, or the equivalents therefor, the whole operating or being made to operate substantially as described.

9. I also claim the improved method of operating the frisket carrier, the same consisting` in causing it to descend and pass in an'incline'd aosition under the delivering tapes and rol ers, while the nippers, V, V, may be approaching the sheet table, Gr, the same enabling the press to be made lower and shorter than when the frisket carriage is moved horizontally under the said delivering tapes or rollers.
