EDWARD HETT, OF NEW YORK, N. Y.

ROLLING-UP MACHINE.

SPECIFIATION forming part of Letters Patent No. 637,589, dated November 21, 1899.

serial No. 709,877. (No motel.)

Application filed March 21,1899.

Tc 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,) in the county of Richmond and State of New York, have invented certain new and useful Improvements in Rolling-Up Machines, of which the following is a specificat-ion.

This invention relates primarily to a rolling-up or developing machin'e designed to be employed in the lithographie or planographic art.

It also relates to certain means whereby a printing-surface may be moved from one position in the machine in which it is mounted to another or whereby the printing-surface may be moved away from the other parts of the machine, so as to facilitate its withdrawal from the machine. Such means may be employed in a rolling-up machine, as shown in the accompanying drawings, or may be employed in other machines working with or upon a printing-surface-such, for example, as a turningover or transferring machine or a printing-press. l.

It also relates to novel mechanism conveniently employed in carrying out the method set forth in my pending application filed October 2l, 1899, Serial No. 734,378, whereby a prepared lithographie surface may be preserved and made ready for use in printing with a colored ink without the necessity of addition al treatment preparatory to applying said colored printing-ink.

Fhe invention consists of the features and combination of features hereinafter set forth, and specified in the claims.

In the accompanying drawings, forming part of this specification and in which like numerals of referencedesignate corresponding parts in the several views, Figure 1 is a Side elevation of a rolling-up machine embodying my invention. Fig. 2 is a front elevation thereof. Figs. 3 and 4 are sectional elevations taken on the lines 3 3 and 4 4, respectively. Fig. 5 is a fragmental view showing a detail, and Fig. 6 is a fraglnental view showing another detail.

Referring now to the specific mechanism embodying the invention and shown in the drawings, 1 is a rotating cylindrical support,

ou which is mounted a curved and generally cylindrical printingsurface and preferably removable lengthwise from the support.

3 is a swinging frame carrying inking- rollers 4, 5, 6, 7, and Sand fixed on a shaft 9, carried by the main frame 10. Loose on the shaft 9 is a main ink-distributing cylinder 11. The side of the frame 3 is provided with gear-teeth 12, meshing with the worm 13011 the wormshaft 14, on which is fixed a gear 15, meshing with the gear 16 on the shaft 17. The shaft 17 carries also a fixed gear 18, which meshes with the gear 19, fixed on the sleeve 37 on the handshaft 20. Thus the hand-shaft, through the train of gearing indicated, is capable of moving the inking-frame 3 so as to carry ,its inking-rollers to and from the printing-surface 2.- 21 is another inking-frame carrying inking-rollers 22, 23, 24, 25, and 26 and fixed on the shaft 27, on which is loosely mounted the main ink-distributing cylinder 28. One side of the frame 21 is provided with gear-teeth 29, meshing with the Worm 30 on the tubular shaft 31, surrounding the shaft 14, and on which is fixed a gear 32, meshing with the gear 33,xed on the tubular shaft 34, surrounding the shaft 17. vThe shaft 34 rvcarries also the fixed gear 35, mesh-ing with the gear 36, Xed on the shaft 20. A hand-wheel 38 on a toothed hub 39, provided with a latch 40, is loosely mounted on the shaft 20 and may be moved into engagement with a recessed head 41, fixed on the shaft 20, or into engagement with the recessed end of the shaft 37, and may be locked by the latch 40 in either position. Thus by means of the train of gearing indicated the inking-frame 21 may be moved so as to carry the hiking-rollers to and from the printing-surface 2 and the hand-wheel 38 may be utilized for the purpose of operating either the inking-frame 3 or 21, These inking-frames, it will be seen, are on opposite sides of the printing-surface, so as not to interfere with each other.

42 is the dampening-frame, carrying the dampening- rollers 43, 44, and 45 and mounted loosely on the shaft 9. It is moved so as to carry its rollers to and from the printing-surface by means of the hand-shaft 46, which earriesa fixed worm 47, meshing with agear 48 on the shaft 49, on which are xed two arms 50 and 51, engaging pinsprojecting from the sides of the frame 42. The shaft 4.6 has a hand-wheel 52. l

The supporting-,cylinder 1 is fixedona shaft 53, which is supported bysuitable means, so

as to be movable and in order that the print-V ing-surface 1 may be moved from one position in the machine to another, for the purpose to be presently explained. In one position the printing-surface is supported in the rollingup `machine, herein shown as in position" to be operated in conjunction with the linkingrollers, as shown in full lines in the ,several figures of the drawings. In another position it issupported over the drip-pan 54, carried by the main frame. In Fig. 4 the printingsurface is shown in this latter position in broken lines. The printing-surface is moved from one position to another by means of a pair of swinging ,arms carried by the main frame and'arranged to engage the-ends of the shaft 53.` These swinging larms are an important feature of my invention, and I will now proceed to describe them and their accessories, referring to one arrangement therethe shaft 57 may be pivotally supported by f the frame in any other suitable manner. As shown in the presentembodiment of the invention, the shaft 53 is not only carried from one position to another by the arms 55 and 56, but is also supported by these arms when in rotative operation. This arrangement has its advantages, but it is not essential, since it is obvious that the shaft may, if desired, be supported by suitable bearings on the main frame when in rotative operation and at such times be disengaged from the arms 55 and 56, which would then be employed only for moving the shaft from one position to another. In the present arrangement the main frame has open recesses 58, arranged to receive the shaft' 53 and limit its backward movement toward the inking and dampening rollers, so that its operating position with respect to these rollers will-be predetermined.

59 and 60 are a pair of swinging arms fixed on the shaft 61 and connected, respectively,

i by links 62 and 63, generally-adjustable, as

shown, with the arms 55 and`56, by means of which the arms 55 and 56 maybe operated to move the shaft 53. The arm 59 is extended to provide an operating-handle 64, which carries a latch 65, arranged to engage notches in ascgmental piece 66, whereby the arms, and

so the printing-surface, are locked in different arms 55 and 5.6 is their availability inthe operation of removing a printing-surface from the machineor in the operation of mounting a printing-surface in place in the machine. The printing-surface 2 shown in the drawings is removable lengthwise from its support, and when itis to be removed from the machine the arms 55 and 56 are swung forward into the position shown in brokenlines in Fig. 4. An arm 67, supported at one end vby suitable means and forming part of an apparatus such as Ishown in `application filed by me on June 13, 1895, Serial No. 552,641, renewed July 12, 1898, Serialv No. 685,764, is then brought into alinement with the shaft 53 on; oneV side of the machine and the arm and shaft coupled together by suitable means, as by the bolt 68. (See Fig. 5.) Y The printing-surface 2 may be then slipped from the cylinder 1 upon the arm 67, the arm 56 having first been disconnected from the shaft 53 and moved out of the way. In order that the arm 56 may thus be moved out of the way, it is especiallyl constructed to admit of this operation, being preferably collapsible. The arm 56, as shown in the drawings, (see Figs. 2 and`6,) consists of a piece 69, pivoted on the shaft 57, and a piece 70, mounted to slide in a recess on the piece 69 and having a recess at its upper end to receive the end of the shaft 53.

Toggle-arms 71 and 72, having a sliding bolt 73 passing through their joint and arranged to enter a recess in the piece 69 are pivotally connected to the lower end of the piece 69 and to the lower end of the piece 70. In this arrangement when the arm 56 is to be disengaged from the shaft 53 to permit the printingsurface 2 to be removed from the support 1 the bolt 73 is withdrawn from the recess in the piece 69, and the piece then slidesdown beneath the shaft 53, the toggle-arms 7lv and 72 bending at the same time at their joint. The arms 55 and 56 are useful not only in moving the printing-surface away from the inking and dampening rollers, so that it may be removed by slipping it lengthwise from its cylinder 1,but they may be used to carry the shaft 53 forward, so that it may be deposited upon a suitable support in front ofthe machine or may be taken from the machine in any suitable manner. It is obvious that these arms may be used in moving a printing-surface from one position to another in connection with various kinds of machines using a printing-surface and for various purposes, and hence I do not wish to limit my claims for them to a rolling-up machine or to any other particular machine.

I will now describe the driving mechanism of the machine whereby the printing-surface may be driven in connection with the inkingrollersor dampening-rollers or alone.Y

74 is the driving-shaft, on which are mounted loosely the small and large gears 7 5 and 76. 77 is a clutch-lever fixed on the shaft 7 8, which carries an arm 7 9 for operating the clutches 80 and 81 on the shaft 74, and there- IIO by locking either of the gears and 76 on the driving-shaft. FiXed on the shaft 57 are the large and small gears 82-and S3, meshing with the gears 75 and 7 6, respectively. Fixed on the shaft 57 is a gear 84, meshing with a gear 85, carried on a stud on the arm 55, and meshing with the gear S6, fixed on the shaft 53. By the train of gearing described the printing-surface may be driven whatever the position of the printing-surface may be, the shaft 53 remaining in operative connection with the driving-shaft when the shaft 53 is in its extreme forward position as well as when it is in its extreme rearward position.

The shaft 57 also has fixed thereon agear S7,

meshing with a gear 88, which meshes with a gear S9. The gears 8S and 89 are carried by studs on the main frame on one side of the machine. (See Fig. 4.) Thegear 89 meshes with a gear 90, loose on the shaft 27 and meshing with the gear 91, carried on a stud on the main frame. The gear 91 meshes with a gear 92, loose on the shaft 9. The shafts 27 and 9 have, respectively, loosely monunted thereon the gears 93 and 94 on the side of the machine opposite from the gears 90 and 92, the gears 93 and 94 being geared in the usual manner with the smaller inking-rollers of the inkingframes 21 and 3, respectively. The gears 90 and 93 are rigidly connected to the inkingcylinder 28, and gears v92 and 94 are rigidly.

connected to the inking-cylinder 11. The gear 94 is also geared with the dampeningrollers, as shown in Fig. 3. Thus the inking and dampening rollers may be driven from the driving-shaft 74 in conjunction with the printing-surface. It will also be seen that the inking-rollers of the frames 3 and 21 may be driven separately in conjunction with the printing-surface. The small and large gears 75 and 76 are provided to change the speed of the printing-surface and the inking and dampening rollers from a higher to a lower rate, or vice versa. In the practical use of the rolling-u p machine shown in the drawings the printing-surface is dri-ven in conjunction with the dam pening-rollers and the inkingrollers of the frame 3 when in the position shown in full lines in the several figures. The inking and dampening rollers are then moved away from the printing-surface and the printing-surface is carried by the swinging arms 55 and 56 into the position shown in broken lines in Fig. 4 over the drip-pan, where the ink is washed off and etched in the usual manner. When the rolling-up operation is satisfactorily finished, the printing-su rface is removed from the machine and when required is mounted in a printing-press.

In the machine already described, and illustrated in the accompanying drawings, I have shown efficient mechanism designed to be used in economically carrying out my improved method. In these drawings the inking-rollers of the frame 3 are intended to be used in the well-known rolling-up operation of the printing-surface.` When this operation has been completed and the black ink employed in such operation has been removed, the inking-rollers of the frame 2l are used Ato-apply the light-colored preserving body. The printing-surface is then removed from the machine and is ready to be used in printing without further treatment. The printingsurface may be used immediately in printing or may be stored away for a time.

The terms lithography and lithographic are herein used in their broader significance and without reference to whether the printing-surface is stone, Zine, aluminium, or other material the printing with which is dependent upon the mutual-repelling properties of grease and water.
