ROLLING-'UP on DEVELOPING MACHIN.

SPECIFICATION forming part of Letters Patent No. 637,587, dated Novembein 21, 1899'.

Application filed January 31, 1898I Serial No.668,1587. (No model.)

T all whom, it may concern:

Be it known that l, EDWARD I-IETT, a citizen 4 of the United States, and a resident of New York, (New Dorp) in the countyof Richmond, State of New York, have invented certain new and useful Improvements in Rolling-Up or Developing Machines, of which the following is a specification.

This invention relates to a rolling-up or developing machine designed to be employed in the lithographie or planographic art.

It also relates to certain hoisting mechanism associated with or forming part of such machine, but which may also be employed in other machines, such as turning-over machines, lithographie or planographic, or other printing-machines. Thepurposeofthehoisting mechanism is to facilitate the handling of the fornior printing-surface in removing' it from and depositing it into its place in such machine.

The invention consists of the structure and the various combinations of elements hereinafter pointed out.

In the accompanying drawings, forming part of this specification, and in which like letters of reference designate similar parts throughout, Figure l is a front elevation of a rolling-up machine embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a central vertical section thereof. Figs. 4 and 5 are a plan and a side elevation, respectively, of a detail. included within the invention; and Fig. 6 is a'fragmental view of another detail.

A is the main frame of the machine, provided with boxes ct, itting in and movable in the recess a in the main frame. The printing or form cylinder B has its shaft B rotatably supported in the boxes a and is driven by the gear-wheel B2, fixed on the shaft. The form or printing-surface b is in the form of a shell, which may be slipped on and off the cylinder B.

C is the main drive-wheel, carried on the shaft C, on which is also mounted the gear C2, meshing with the gear D, which in turn meshes with the gear E2 on the shaft E', which carries the main ink-distributing roller E. The ink-distributing rollers e, e, e2, and e3 carry the ink from the roller E to the forminking rollers f f' f2, which supply it to the printing-surface b. The rollers E, e, e', and e2 are connected from one to the other by gears', (see Fig. 1;) and the roller e3 is connected with the roller e2 by gears p', 192, and (See Fig. 4.) The inking-rollers e e e2 e2, gear p', and form-inking rollers ff f2 are mounted in a swinging' frame F, xed to the shaft E', on which turns the roller E, the frame being actuated by suitable mechanism, hereinafter described, whereby when the swinging frame is moved upward the inking-rollers are carried away from the form-,cylinder to permit the form-cylinder to be lifted from place or deposited in place. For the purpose of moving the swinging frame F with itsink- V`ing-rollers l mount a worm R on the side of the main frame, which meshes with a wormgear on the rear of the frame F at one side. A hand-wheel R on the shaft r2 operates the worm through the beveled gears r r. It' desired, a worm R and worm-wheel could be arranged for both sides of the frame F. The worm and worm-gear operate to lock the'frame at any position desired. The ink-roller E receives its ink-supply from the ductor G,which takes ink from the fountain H. The ductor G vibrates between the fountain and roller E, being carried by a pair of arms G', mounted on a rock-shaft g, which is operated by the arm g', made fast on the shaft g, the arm being intermittently actuated bythe cam c, carried by the main shaft C. The waterfountain roller J supplies water to the printing-surface through the ductor K, rider L, and dampening-rollers L and L2, the ductor K being supported by arms K', carried by the Avrock-shaft 7c, which is operated by the arms o, made fast on the shaft la. The arm lo is intermittently actuated by cam c on the shaft C' or cam similar thereto. The rider L is driven from the gear E2 by the gear M,wl1ich meshes with the gear E2 and with a pinion M', which is supported by links and is in engagement with the gear Z on the shaft of the rider. The rider L and rollers L' and L2 are supported by a swing-frameN, carried on a cross-rod N', so as to be capable of swinging on this rod as a center to and from the cylinder B. The gear M is carried on a pin which is secured to the main frame and'extends through slot n in the frame N, this slot thus enabling the frame N to move freely IOO '2 estasi without obstruction from the pin. The frame N is moved Aback and forth by crank P and cams P, carried on a shaft P2 and working in recesses N on the frame Y.

The inking-rollers e2 and es are given the usual longitudinal reciprocating movement coincident with their rotary movement. This is accomplished by the following means, (shown clearly in Figs. 4 and 5:) On the ends of the shafts of the rollers c2 and e3 at one side of the machine are the grooved hubs h and h', the grooves of which are engaged by the ends of a yoke j. This yoke is rigidly connected at its middle with a spindle j,which passes through the bracket h2, projecting from the frame F, and is made fast to one end of a vibrating arm j?, the other end of which is engaged by an eccentric o, carried by a spindle o', which is supported by the bracket h2. The spindle o' is provided with a worm-wheel o2, meshing with the worm p, projecting from the frame F, and provided with a gear p',

` which is in engagement with the pinions p2 and p3 on the shafts of the rollers e2 and e3. By this arrangement the roller e2 not only drives the roller e3 through the connectingpinions p2, 29', and 293, but through the worm 1J, worm-wheel o2, and eccentric o also causes the arm j@ to vibrate, thus giving a rocking movement to the yoke j through the connecting-spindlej. This movement of the yoke imparts the desired reciprocating vmovement to the rollers e2 and e3.

Mounted on the main frame is a pair of hoisting-arms S, provided with recesses s at their upper ends to receive the ends of the shaft B' of the form-cylinder B. These arms S are arranged to move up and down in slideways S and are provided with actuating mechanism whereby the printing-cylinder when the inking-rollers and dampening-rollers are moved away from the printing-cylinder, as above described, may be lifted from its normal working position up above the main frame` into the position shown in dotted lines, Fig. 3, for the purpose of removing from orfixing on the printing-cylinder Ba printing surface or shell b. In the present embodiment of the invention this actuating mechanism is constructed as follows: Screws T, supported on the sides of the main frame, work through threaded collars s', fixed on the arms S. When the screws T are turned, the collars s are carried up or down, as desired, and with them the arms S. The screws T are provided with beveled gears t, which engage with the beveled gears i' on the shaft T', which is driven by the shaft U, whose gear u meshes with the gear t2 on shaft T. The shaft U has a beveled gear fa', which meshes with the reversed beveled gears fu or o on the main shaft C'. These gears o and o' are loose on the shaft C', and between them is a clutch W, operated by the rod NV', whereby either of the gears o or n' can be made fast on theshaft Ci'. Both are in mesh with the gear u', but only the one which is made fasten the shaft by the clutch drives the shaftU for the time being. The shaft U may thus be turned in either direction by the shaft C', whereby the hoisting-arms S are raised or lowered, as desired. One of the collars s is detachable from its arm S, the attachment and detachment of these parts being eected by means of a removable pin s2, passing through apertures in the collar and arm, as shown in Figs. 1 and 3.

X is a transporting-stand having a revoluble arm provided with blocks and adapted to support a printing-surface in taking such surface from or putting it on the form-cylinder.

O is a drip-pan supported underneath the form-cylinder to catch the drip when the print-l ing-surface is being rolled upor developed.

Suppose now it is desired to fix a printing-'surface h in the rolling-up machine to develop it. The hand-wheel R' is firstturned to swing the frame F upward and with it its inking-rollers,as above described. The crank P' is then turned to swing the frame N back andwithitthedampenng-rollers. The form-v cylinder B is then free from all obstructions to its upward movement. The main shaft is now turned slowly, the gear v on the mainshaft having been first made fast on this shaft. This movement of the shaft C operates through the train of gearing already described to lift the arms S, Whichin turn lift the formcylinder B-,together with its shaft and the bearing-boxes a, above the main frame'and into the position shown in dotted lines, Fig. 3. The stand X being in proper position beside the machine, its arm carrying the printingsurface, is brought into alinement with the shaft B' of the form-cylinder, and the bearing-box a next the stand X having been re` moved the shaft B and armsX are connected at their abutting ends, so as to form for the time being a straight rigid shaft.

In Fig. 6 is shown convenient means for securing theabutting ends of the shaft B' and arm .r together. of the shaft, and :r2 is a sliding bolt, which may, as shown, be spring-pressed. The bolt slips into the socket and effects the connection desired. The collar s' and arm S are now disconnected by drawing out the pin s2, and the arm S, which is the one on the side next the stand X, slips down out of the way of the printing-surface, which is then slipped along the arm a: and onto the form-cylinder B, where it is secured by suitable means. The arm is then brought up to support the end of the shaft B', the arm .cc is withdrawn, the bearing-box a is put on the shaft B, `and the shaft O -is rotated, the gear o' having been previously clutched on the shaft and the gear o unclutched. The screws T are in this way reversed and the arms S lowered to bring the form-cylinder B,with its printing-surface b, into the proper place in the machine.

The machine shown in the drawings is a rolling-up or developing machine, and it is to be understood, of course, that the printing- IOO IOS

IIO

b' is a socket in the end surface before being mounted in this machine has already received the transfers which are to be developed. In carrying out the developing operation the printing-surface is preliminarily etched by being gummed up and dried in the usual way, after which it is washed off with water to remove the gum and, as is usual, is again washed with water and turpentine to remove the ink. The dampening-rollers are then applied to the printingsurface by swinging forward the frame N and the printing-surface is slowly rotated. The frame F is then s-wung down to bring the inking-rollers into operation with the printingsurface, which is then inked, resined, and fully etched with dilute acid ,and washed off and retched, if necessary. It is of course obvious that the etching may be prolonged until it becomes deep etching and the surface developed so as to become a relief or intaglio printing-surface. The printing-surface is in this way rolled up or developed in the machine shown in the drawings and is then ready to be taken from the form-cylinder and transported to a printing-press or a proper place of storage and used as a printing-surface. The operation of taking the printingsurface from the rollin g-u p machine need not be described, as it is the reverse of the operation of putting it in the machine and will be readily inferred from the foregoing description.
