SPECIFICATION forming part of Lettes Patent No. 761,560, dated May 31, 1904.
' A .lippnootiooo tied November 14,1395. senor No. 568,917. (No model.) 2
To @ZZ whom it mag/ concern- Be it known that I, WILLIAMI-I. R. ToYE, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and-Improved Printing-Press, of` which the following is a true and exact description, reference being had to the accompanyingdrawings, `which form a part of this specification.
My invention relates to the construction of printing-presses, and especially tovwhat are known as multicolor-printing presses, my object being to providea press of this kind in which the type-forms may be flat and in which l5 the machinery shall be simple, easily gotten at for adjustment, and especially well adapted for good and accurate work.
The nature of my improvements will be best understood as describedin connection with the drawings, in which they are illustrated, an
in which y Figure 1 is a side elevation ,of the press embodying my improvements; Fig. 2, a crosssection on the` line m fr of Fig. l; Fig. 3, a cross-section on the line y y' of Fig. 4C; Fig. 4, a cross-section on the line z z'of Fig. 3; Fig. 5, a central longitudinal section through the air-pump, which forms a detail of my mechanism; and Fig. .6 is a side elevation of a portion of the platform D, showing how the racksections are secured to it.
A indicates the framing of the machine, which carries tracks or guideways A.
B is the main driving-shaft, to which are attached fast and loose pulleys, (indicated at B and B2,) B3 indicating a driving-belt. Secured also to the shaft Bare spur-wheels B4 B4 and a cam- B2. The spur-wheels B2 B2 engage with and drive gear-wheels C' C, which 4O4 are secured to a shaftC, to which shaft is also secured agear-wheel C2 and two sprocket- --wheels C3 C3, supported on rollers E. Resting in tracks or guides A is a table or platform D, which, as shown, is provided with a depending slotted arm D2. The platform is adapted and intended to support a series of type-forms-'such as are indicated at G, G', and G2-and on veach side of the type-forms are registering surfaces, (indicated at D2) and on one side of each type-form is a sectional rack D3. These rack-sections are in the construction shown adjustable longitudinally, beingr fastened to the edge of the `table by bolts passing through slots, as shown at cl3, Fig. 6.
Ev indicates a suitably-supported shaft lying parallel and in the same horizontal plane with the shaftfC'and having secured to it sprocket- .wheels (indicated at E/ corresponding with the sprocket-wheel C3 on the shaft C. y
F F indicate drive-chains, one running over each pair of sprocket-wheels C3 and E', and F indicates a pivoted block adapted to slide in the slotted arm D2 and having its pivot secured to the two chains FF. It is obvious, of course, that the slotted block will revolve with the chainsF F and will by its revolution cause the slotted arm D2 and the platform D, to which said arm is secured, to reciprocate, thus giving to the type-forms the desired reciprocating movement. This particular mechanism for actuating the platform D and the typeformsv supported upon itis, I believe, novel and forms a feature of my invention; but it will be understood that any device for reciprocating the platform may, if-desired, be used .in connection with the other features of my invention.
The shaft C not only drives the sprocketwheels, but through its pinions C2 and idlergear-wheels H it drives the shaft I, the gearwheel Hengaging with gear-wheels K2, which are secured to said shaft in a manner to be hereinafter described. The shafts I, I', and I2 each support a segmental impression-cylinder, (indicated at J.) This segmental -impression cylinder or surface is preferably cast with and as a part of the shaft I, the segmental surface being connected with the shaft by arms .I and a counter-weight, as indicated at J2, being preferably cast on the back of the shaft to balance the segmental impression-cylinder. On one side of each segmental impression-surface J, I provide a segmental rack J 3, so placed and arranged as to register with and engage the segmental racks I)3 when the impression-cylinders come into operative relation to the type-forms carried by the reeipro` adjustment thereof on the shaft I. CarriedV by the hubs K are carrier-sheaves K4 and also gear-wheels K3, said gear-wheels serving to drive the shafts I, I, and I2 and said carriersheaves to support and actuate flexible carriers, (indicated at L,) and to which carriers are secured the gripping devices l l, &c., the carrier-slieaves being provided with recesses (indicated at c) at the points where the gripping-bars come in contact with such sheaves. Motion is transmitted from the shaft I to the shaft I by means of the gear-wheels M2 M M. Mounted on the shafts N are also supported guide-sheaves, around which pass the iieXible carriers L, as indicated in the drawings. M otion is transmitted also from the shaft L to the shaft I2 by means of similar gearing, (indicated at M3, M4, and M) also supported on shafts N, which carry as well guide-slieaves for the flexible carrier-bands. Other guidesheaves for the carrier-bands are supported and actuated' by a shaft P, to which shaft is secured gear-wheels P2, driven from the gear K2 on shaft I through an idler-pinion P.
The function of the cam B2, secured to the shaft B, is to drive the piston of an air-pump (indicated at O) and from which passes a pipe C', connecting, through a pipe O2, with the shafts N, all of which arehollow and provided with perforations, as best indicated in Fig. 2, and th rough which perforations the blast from the air-pump constantly issues. The reason for this construction is that by means of the blast issuing from the shafts N the sheets passing over such shafts are kept from coming into actual contact with them. Q indicates a sheet-delivery device by which sheets of paper are delivered to the grippers on the carrier-bands, and R indicates a receiving device upon which are deposited the sheets after they are taken from the grippers by the take-off roll T.
S S S indicate inliing-rolls for the typeforms G G G2.
The action of my improved press is simple, andindeed obvious from the drawings and description already given. Each sheet receives as many impressions as there are printingcouples in the machine in passing once through the machine. Ait the same time ample protating segmental impressioii-surfaces corresponding in number with the type-forms and each said impression-surface bcingadapted to operate in connection with one of the series of Vtype-forms, each said impression-surface being secured to one of the series of shafts, means for actuating the reciprocating table and the rotary impression-surfaces whereby each impression-surface makes one complete revolution coiitemporaiicously with each complete reciprocatory movement of the table, carriersupporting sheaves secured to each shaft on each side of the impression-segments by means permitting their angular adjustment, a continuously-inoving endless-belt carrier passing over said sheaves and successively between each type-form and its impression-surface and moving at the same speed as the impressionsurfaces, a series of sheet-grippers secured to said carrier at a distance apart equal to the distance traveled by a point on the impressionsurface during a complete revolution and means for supporting and guiding the carrier between the impression surfaces whereby each gripper and a sheet held therein is made to pass successively between each printingcouple. i
