SPECIFICATION forming part of Letters Patent No. 637,567, dated November 21, 1899.

Application filed November 13, 1895. Serial No. 568,795. (No model.)

To all whom it may concern:

Beit known that I, EDWARD HETT,a citizen of the United States, and a resident of New York, (New Dorp,Staten Island,) in the county of Richmond, State of New York, have invented new and useful Improvements in Transfer- Presses, of which the following is a specification.

My improvements relate primarily (although not exclusively)'to transfer and printing presses such as are adapted to do lithographic work, and especially such as involve the use of rounded or cylindrical printingsurfaces-such, for instance, as are shown in my applications for patents serially numbered 718,570, filed May 27, 1899, and 537,582, filed February 7, 1895, and such as are well adapted to carry out the methods of my applications serially numbered 703,082, filed January 23, 1899, and serially numbered 695,281, filed November 2, 1898. r

The object of my improvements is to perfect the operations and mechanisms involved and to better adapt the apparatus to practical use.

The accompanying drawings, which form a part hereof, represent a lithographic transfer-press which embodies my improvements.

Figure 1 is a side elevation of the machine. Fig. 2 is a longitudinal section taken on the plane of the line 2 2 of Fig. 5. Fig. 3 is a rear elevation of the machine. Fig. 4 is a top view with the rear portion broken away to enable the other parts to be shown on a larger scale.

The machine of the drawings is a so-called transfer-press used in lithographic work and is in its general features and purposes and operations similar to the transfer-press shown in my pending application filed J anuary 23, 1899, and serially numbered 703,082. A reciprocating bed is adapted to carry the setting-up plates. A cylindrical lithographic surface is adapted to be driven positively with the reciprocating bed while the latter is reciprocating under it, to be moved toward and from the path of the reciprocating bed whenever desired and to be driven positively printing-surface. This swinging frame car r in the dam enin -rollers is swun bva y b o b chain of mechanism including a worm and a Worm-"wheel; The printing-surface has an adjustable stop limitingits motion in the direction toward the inking and dampening The water-supply roller is vibrated rollers. toward the water-distributing rollers by an imp sitive driving mechanism -that is to say,

one working through a spring connectionwhereby thecontact between the rollers is at alltimes a spring-pressure contact and whereby also when the supply-roller meets with any positive obstruction to its vibration toward the distributing-rollers the furthermotion of the driving mechanism is expended in straining the spring. The frame has two slideways for the bed, side frames for the driving mechanisms, the printing-surface,

the dampening devices, and the main ink-' distributing roller,a back frame for the swinging ink-frame, the ink-fountain and the vibrating ink-roller and the .back ink-rollers, and braced supporting-legs. The brass was tor-rider is positively driven and through a chain of gear-wheels carried on a chain of links, whereby it is positively driven whatever the position of the swinging frame cardriving-shaft of the machine 14 is by proper rying the water-roller. The chain of links carrying the'chain of gear-wheels driving the printing-s11 rface have holding-arms to secure them in place when uncoupled from the printing-surface, and there are otherdetail features of novelty, as shown.

A description in detail of themachiue a.

the drawings is as follows: I

The frame of the machine consists of two slideways 10, two side frames 11, a back frame 12, and braced supporting-legs 13. The main reversingmechanism (not shown) adapted to be driven in either direction. It carries a .double friction-clutch 15, adaptingit to drive either the intermeshing beveled gear-wheels" 16 (and so through suitable gear connections the bed-reciprocating screw 17 and the printing-surface when it is lowered) or the intermeshing WOI'IIL and worm-wheel '18, (and so through suitable gear connections the driv has oneach side a rack 22, which is made vertically adjustable, as indicated in Fig. 12, the bolt-holes in the racks being vertically elongated for that purpose, enabling the bed to be used with setting-up plates or with impres- Sion-surfaces of different thicknesses. These angle-piece 23.

shaft 27, they carry on their center pivot a racks take into pinions 71 on the shaft of the printing-surface when the latter is lowered into contact with the setting-up plate or impression-surface on the bed, whereby the bed and printing-surface are driven relatedly and positively together whenever the bed is under the printing-surface and the printing-surface is lowered to the bed. In practice the racks 22 and pinions 71 willbe marked and-the pinions always so lowered that a gi ven tooth of the pinion will take into the same recess of the rack, whereby with'the arrangements immediately to be described a whole series of accurate and related transfers or prints may be made. The bed 21 has a steel angle-piece 23, forming one end and one side of its recess for the reception ofthe setting-up plate or impression-surface, and on the other side and end of that recess it has adjusting and fastening devices 24, adapted to take against the side and end of the setting-u p plate or impression surface and to adjust andsecure the same snugly and reliably in place in the corner formed by the steel angle-piece, as shown in Figs. 11, 13, and

14. Two forms of adjusting and fastening devices are shown in Figs. 11, 13, and 14. Either or both may be used or still other forms. In practice the setting-up plates an'dimpression-surfaces will be accurately cornered to correspond to the corner formed by the steel Thus a whole series of accurate and related transfers or prints may be made. Under the ordinary zinc setting-up plate used in transferring work in lithography itwill be found useful to employ a rubber blanket or sheet one-quarter of an inch thick or thereabout. Both prints and transfers are the better for it. p

The printing-surface or surface onto which the transfers are to be made and from which prints are subsequently to be made is a tube or cylindrical form 25, carried on a form-cylinder26 and readily'removable therefrom and replaceable thereon. The shaft 27 of the form-cylinder may be driven either from the beveled gearwheels 16 through the reciprocating bed, as already explained, or it may be driven from the worm and Worm-wheel 18 through the shaft 19 and the chain of gearwheels 28 on the chain of links-29,.as shown. (See Fig, 8.) lhe upper link of the chain of links has at its upper end a split and hinged collar 30,-which is adapted to embrace the shaft 27 of the form-cylinder and be locked thereon and carried thereby. This collar may be readily unlocked by unscrewing the nut from the split part of the collar, when the upper part can be thrown up and back and the upper gear-wheels 28 thereby unmeshed.

This unmeshing should always be done when it is desiredtolo'wer the printing-surface and drive it-from the beveled gear-wheels 16 through the reciprocating bed or when it is desired to lift it out of the machine, as hereinafter described. To hold thechain of links 29 in place when they are uncoupled from the holding-arm 31, which has a hook that is adapted, as shown in Fig. 8, to take over some part 107 of the frame. The upper link 29 also carries loosely pivoted on itaholding-arm 122, which when to be used is intended to be swung by hand until its foot rests upon the adjacent upper edge of the frame-piece 121, where when the holdingarm 31 is sprung down into its holding and locking position the arm 122 will hold the upper link 29 so that its seat for the shaft 27 is exactly lined with the slideways at the sides of the machine, whereby the shaft 27, with the sliding boxes and all that it carries, may readily be lifted out and replaced.

The shaft 27 of the form-cylinder is carried in sliding boxes 32, which slide vertically in suitable slideways 33in the side frames of the machine. These sliding boxes are adj ustabl y and removably mounted on the heads of pressure bars or rods 34, as shown, two nuts 103 on the pressure-bars below the sliding boxes being the means of adjustment and of locking or fixing the adjustment and one nut 104 on the pressure-bars above the sliding boxes being the means of securing the sliding boxes in the thus-adjusted position on the pressurebars. The pressure-bars are raised and lowered by an eccentric 35, worked by a lever 36. This gives great power both in the raising and in the lowering. When the pressurebars 34 are raised, an eccentric 105, loosely pivoted on the bars just above a projection of the frame, revolves by its own weight, and thereby locks the bars in their upper position, as shown in Fig. 23. To lower the bars, the eccentric 105 must firstbe revolved back. An adjustable stop 106 limits the upward motion of the pressure-bars and so limits the motion of the printing-surface toward the inking and dampening rollers. The slidingboxes 32 have an internal brass lining 37, (shown in Fig. 9,) the inner vertical face of which regulates the lengthwise position of the revolving form-cylinder, taking the wear incident to such regulation. To render it adjustable to take up for this wear, this internal brass lining 37 is externally screw-threaded and its seat in the sliding box is correspondingly internally screw-threaded. To adjust the brass lining inward or outward toward or from the end of the form-cylinder, it is therefore necessary only to screw or unscrew it in its seat and then to lock it in its adjusted position, as by the pin 38.

The main ink-distributing roller 39 is carried by the side frames of the machine and is driven from the worm and worm-wheel 18 through the shaft 19 and shaft 40 and gear connections. The shaft of this main ink-distributing roller has at one side of the machine other side of the machine a wheel 45, having a spiral peripheral groove in which works a pin on the end of a lever-arm, as shown, the other end of the lever being connected to the two iron riders 43 and 44, so that the revolving of the main ink-distributing roller also oscillates the two iron riders axially. The shaft of the main ink-distributing roller also has a cam 46, which vibrates one arm of a bell-crank lever 113, the other arm of which carries the bearin gs of the vibrating or ductor roller 47, whereby that roller is with little friction and positively vibrated between the ink-feeding roller 4 8 (in the mouth of the inkfountain 49) and the main ink-distributing roller 39. The ink-feeding roller 48 has its bearings in the ink-fountain and is rotated by hand by a handle 50, which through a pawl works a ratchet-wheel on the ink-feeding-roller shaft. The back frame carries the ink-fountain on two brackets. The back frame also carries the back ink-spreading roller 51. The swinging frame 52 is centered with the main ink-distributing roller, but has its bearings in and is carried by two brackets 79 from the back frame of the machine, as shown in Figs. 4 and 9. The shaft of the main ink-distributing roller passes loosely through the brackets 79. Thus weight is removed from the shaft of the main ink-distributing roller and wear is reduced. The swinging frame 52 has one of its strengthening cross-bars 53 lengthened at both ends, so as to rest upon adjustable stops 54 in the side frames of the machine when the swinging frame is in its lowest position, (see Figs. 10 and 4,) whereby the swinging of the inkingrollers 55, which are intended to contact with the printing-surface, is adjustably limited as a whole in the direction toward the printingsurface. The inking-rollers 55, which are adapted to contact with the printing-surface, are each of them adjustably mounted in the swinging frame, being mounted in sliding boxes 56, which permit an adjustment namely, by screwing them toward or from the printing-surface. The two iron riders 43 and 44 and the first leather ink-roller 42 are also mounted in sliding boxes, as shown in the drawings, and are adapted to be adjusted by hand screw-wheels, both to adjust them to the adjustment of the inking-rollers 55 and also to permit of their being screwed up wholly out of contact with the rollers 55, as when the press is notin operation. The swinging frame 52 is swung up and down by a hand screwwheel 57, Fig. 1, through suitable connections, as shown in Figs. 2, 3, 4, and 6, including a worm 58 and, driven by the worm, a wormwheel 59. Thus power is attained and self-- locking in any position. The entire train of mechanism is hand-wheel 57, gears 80, shaft 81, beveled gears 82, shaft 83, worm 58, wormwheel 59, shaft 84, pinions 85, and rack 86 on the swinging frame 52.

The water-supply fountain is of any suitable construction. It is suitably supplied with water. It is shown in the drawings as a roller 60, in which case itis rotated by a series of belts 114 114 115.

The last of the series, 115, may have springs in it or be arubber hose or an endless chain with sprocket-wheelsto permit the vibratione5, arm 92, adjustably fixed on shaft 89 by set the brass rider when permitted (Shown in Figs. 2 and 7.-)

of the water-supply roller. The water-sup? ply roller is vibrated toward and from the brass water-rider6l in the following manner: The shaft of the main ink-distributing roller 39 has a cam 62, which through suitable connections rocks the arm63, (see Figs. 2, 7,15,

and 16,) which takes against and rocksthe arm 64 (on which the bearings of the watersupply roller are carried) toward the brass water-rider 61. Between the cam 62 and the arm 63 is a spring 65. In its working adjustment it is strong enough and strained enough vibration of the water-supply roller withthe rise of the cam 62, then the further positive motion of the rise of the cam 62 is merely taken up by the spring, the spring being thereby much further strained. The watersupply roller falls back by gravity away from r I ycam 62and spring 65, a stop 99 on the frame being taken against by a projection 100fi n the arm 64,

this limitingthe backward movement. The train of mechanism from cam 62 towaterroller 60 is cam 62, roller-arm 87 rocking hub 88, loosely mounted on shaft 89, arm 90, solid with rocking hub and carrying pin 91, spring screw 93 to properly strain spring 65 between arms '90 and 92, the spring tending to keep the arm 92 and pin 91 in contact, arm 63, fixed with arm 92 011 shaft 89, and, finally, arm 64, carrying'roller 60. The swinging frame 66 (see Figs; 2, 7, and 15) is pivoted in theside frames of the machine at 94 and carries the bearings-0f the brass water-rider Gland of the dampening-rollers 67; that contact with the printing-surface. It is swung by a hand screwwheel 68, (see Fig. 1,) the connection including a worm 69, a worm-wheel 70,.shaft 95,

. forked arms 96, and pin 97 on swinging frame 66, whereby power and self -locking are socured. The swinging frame 66 strikes against astop 98 on the arm 64 (which carries the water-supply roller) when that swinging frame 66 is swung backwardly toward that roller, the two rollers 61 and 60 at such time being just clear of each other, as indicated in dotted lines in Fig. 15,whereby the two rollers are prevented from striking against or resting'on each other at such time. On the other hand, when the arms 64 swing toward the swinging frame 66 it is the two rollers 61 and 60 that contact and not the frame 66 and the stop 98, all as clearly shown in the drawings. The worm-wheel70 in the train of mechanism which swings the frame'66' has on it an adjustable stop 72, which takes against the side frame, as shown in Fig. 1, and thus ad- 'be in "positive driving connection with the driving-shaft 19, whatever the position of the swinging frame 66, for this swinging frame 66, like the swinging frame 52, isoften to be swung while the parts are running. To describe it in detail, this end is accomplished in the following manner: Gear-wheel 116, fast on driving-shaft 19, meshes with gearwheel 117, the latter with gear-Wheel118, the 5 latter with 119, and the latter with 120. Gearwheel 120 is fast on the shaft of the brass water-rider 61. Gear-wheel119 is carried on the center or connecting pin or pivot of a chain of two links 74 74, the outer end of one of which is carried loosely on the shaft of the brass water-rider 61 andthe outer end of the other on the same shaft as gear-wheel 118. The shaft of gear-wheels 117 and 118 are, like that of 116, not capable of reciprocating motion.

The bath 75 is made of suitable material to resist the action of the acids used in etching, and it isadapted to be mounted in the slideways 10 of the main frame and lunder the printing-surface, as shown in Figs. 17 and 18, so that the printing-surface can be lowered .into it, as indicated in dotted lines in Fig. 19,

and revolved in it. This bath 75 has a suitable inlet, such as the funnel 75, whereby water orgum and water or acid and water may be introduced as desired, and a suitable drain 76 for draining oif whatever may be in the bath. This drain is shown with a twoway cook 77, whereby the liquor drained off may be saved or may be allowed to run to waste. 78 is the water-supply pipe. It may have a branch 102 to the water-supply roller 60, reaching the same through a bushing, the branch including a filter 101, as shown in Fig. 1.' Heretofore lithographic surfaces have been ordinarily washed and etched and otherwise prepared for printing by the use of brushes, sponges, ac. My improved means of accomplishing such operations, whereby a roundedor cylindrical lithographic surface is revolved in or-moved through a body of liquor held in a bath, (either washing liquor or etching liquor, or otherwise,) produces more perfect and delicate work.

One of the pinions 71 on the shaft 27 that carries the form-cylinder is loosely and removably keyed on that shaft, as shown in Figs. 17 and 22, so that the printing-tube may be readily removed from and replacedv on the form cylinder 26. To accomplish this removal, it is only necessary tovunscrew the securing-nuts 104 at each end of the shaft, unlock and throw up and back the hinged collar 30, raise the shaft 27 and sliding boxes 32 out of the slideways 33 by any suitable hoisting apparatus (as by that shown in my application serially numbered 685,7 64, filed July 12, 1898,) slip off the loosely-mounted pinionwheel 71 at one end of the shaft, and then slip off the printing-tube 25 from the formcylinder 26 or slip both printing-tube and form-cylinder off from theshaft, as desired. Any suitable means may be resorted to to accurately place the printing-tube 25 on the form-cylinder 26, when replacing it, and to hold or fix it in such place, as a groove or slot in one and a lug in the other to fix and hold circumferentially and a stop and lock or catch to fix and hold longitudinally. These details are not shown in the drawings.

The ink-fountain 49 is preferably an airtight ink-fountain, as shown. Figs. 3 and 24 show a portable ink-reservoir of suitable size to hold a considerable quantity of ink. It has an outlet 107, adapted to be securely attached to the inlet 108 of the air-tight inkfountain and to be readily detached therefrom, as by the screw-collar 109, and it also has a containing-cylinder 110 and a pressure device 111, adapted to force the ink out through the outlet of the reservoir into the ink-fountain-ats, for example, the pistonhead, screw, and hand-wheel shown. This entire pressure device can be readily screwed on or unscrewed from the reservoir. The portable pressure ink-reservoir has especial importance in connection with the use of airtight ink-fountains, because the supply-inlets -to such ink-fountains are small, and it also has importance in connection with multicolorprinting and especially with multicolor lithographic printing, for the mixing and manipnlation of the colors may be done away from the press and conveniently and in a cleanly way and without rendering the press uncleanly or getting the ink dirty, and quickdrying inks may be handled in this way and kept from the air.

The operation of the machine will be clear from the above description to one skilled in lithographic transferring.

Many features of the invention are capable of use in machines whose general form and construction are very different from that of the drawings, and many of them are capable of use in presses other than transferringpresses and in work other than lithographic work, although they find their best use in ,tube or cylinder, after receiving the transfer,

as described, is subsequently developed into a printing-surface or into what character of printing-surface it is subsequently developed, whether into a lithographic-printing surface or otherwise.
