PRINTING-PRESS.

SPEGlFIGATIGN forming part of Letters Patent No. 731,790, dated June 23, 1903. Application filed May 6, 1899. Renewed October 30, 1902. Serial No. 129,508. (No model.)

I which the following is a specification, referprinting-machines where the paper is takenence being had drawings.

My invention relates to that class of platen therein to the accompanying from a continuous web or roll, and has for its object to construct a press that is especially adapted for book and newspaper work.

The invention particularly consists in a stationary platen having a curved face and a reciprocating type-bed in operative relation thereto supported by means of pitman-rods,

so that it will be free to rock thereon, said pitman and cranks imparting a rocking motion thereto, so that but a small strip of the paper will be printed upon at a time, thus insuring perfect contact and combining all the advantages of a cylinder-press with those of the platen-press.

The invention further consists in the construction of the press in an exceedingly simple form, so that it maybe manufactured at such a price as will bring it within the reach of the ordinary job printer, thereby enabling him to do high-classwork.

The invention further consists in the arrangement of the inking device and in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described, and shown in the accompanying drawings, in which Figure 1 is a side elevation of a double-deck press of my improved construction. Fig. 2 is a section therethrough on line a; 00, Fig. 1. Fig. 3 is a longitudinal section through the type-bed and guides, showing the inking carriage and roller in elevation. enlarged sectionthrough. one corner of the type-bed, showing the manner of pivotally securing it to the upright. Fig. 5 is a section through one of the slotted bearings in the upright, suspending the outer end of the inking-table. Fig. 6 is a side elevation, showing the curved platen and the type-bed cooperatingtherewith, in full and dotted lines. Fig. 7 is a plan view of one of the type-beds.

Fig. at is an In illustrating my invention I have taken a double-deck press of my improved oonstruction, in which A is the base and B the four corner uprights stationarily secured thereto, as shown in Fig. l.

O is the drive-shaft, secured upon the base A in suitable bearings a and provided on its ends with the fly-wheels D D and the drivepulley D.

E represents suitable pinions secured upon the shaft just inside of the bearings and meshin g with the gears F, secured upon the crankshafts G G, said shafts being supported in suit-able bearings on the base on opposite sides of the shaft 0.

Connected to the crank-shafts G G are the pitinen H, their upper ends engaging in the pockets I in the type-bed J, and K is rib formed on the under side of the type-bed to strengthen the same andalso forming a guide for the pitman. The base of the pockets I are form ed with the rounded portion 1), so that the upper ends of the pitmen will have a rollvery little lubrication.

L L are the upper and lower platens stationarily secured by means of suitable collars upon the uprights B, as shown, their under faces being slightly curved.

M represents four corner-uprights loosely supported in the base-plate, as shown, and of somewhat shorter length than the uprights B. Loosely secured to the top of these uprights is the upper type-bed N, the type-bed J being likewise secured to the uprights near their middle portion. Sleeved upon the uprights M, below the type-bed J, are the springs O, which rest with their lower ends upon the base A, thereby greatly easing the shock in the lowering of the type-beds and relieving the pitman of its weight in the normal position of the parts. One of the cranks G is slightly offset in relation to the other to correspond to the curve on the face of the platen, so that one end of the type-bed will strike upon the platen slightly in advance of the other end, thereby imparting a rolling contact to the paper passing over the curved face of the platen, and thereby insuring a perfect and even contact throughout, which enables me to run off the finest class of work upon a press of this kind. In order to permit of the slight tilting mg contact therein, thereby requiring but g of the type-bed, I preferably connect them to the reciprocating uprights M by means of the connection shown in Fig. 4, in which the collars and. edges of the openings are suitably curved to correspond to the amount of inclination desired. I may accomplish the same re sult by means of a loose fit, the springing of the uprights, or bya ball-and-socket connec tion.

P represents uprights to one side of the press a distance away equal to the movement of the inking-carriage, a suitable crossbar connecting it to the framework.

Q represents the inking-tables pivotally secured to the uprights P by means of slotted bearings, as shown in Fig. 5. I may, however,

' to lower, the

accomplish the same purpose by merely having the inking-table slide upon the cross-bars R, as shown in Fig. 2. The inner end of the inking-table is pivotally secured to the edge of the type-bed in suitable bearings formed thereon.

S is an idler-pulley secured to the framework, and T is a belt, one end passing over the idler-pulley and secured to a cross-pin d on the type-bed J.

T isa transverse shaft secured in bearings upon the uprights P, upon which is rotatably mounted the pulleys T and T towhich are respectively secured the ends of the belts T and T. a

U represents idler-rolls over which the belts T pass for the upper set of inking-rolls, while V is a pulley loosely sleeved upon the shaft V, to which the ends of the belts T are attached, a coil-spring of sufficient power to draw the inking-carriage back across the typebed during the separation of the parts being sleeved on the shaft V, having one end secured thereto, the other end being attached to the pulley V.

The inking device preferably consitss of three or more rollers e, connected to a suitable bracket f, having the flange g, to which the belts T are attached, and the lip h, traveling in the guide-groove 7;, formed alongside of the chase and secured to the type-bed by means of the screws 7'. It will thus be seen that as the type-bed J moves upward the belt T will move therewith and the pulleys T and T caused to rotate, thereby drawing the inkingcarriage, through the medium of the belts T across the type and inking-table (to the-position shown in dotted lines in Fig. 2) against the tension of the coil-spring mounted upon the shaft V as soon as the type-bed J begins pull upon the belt T being released, and the coil-spring (now being under tension) will draw the inking-carriage back across the type-bed to the position shown in full lines, suitable stops being provided to limit the movement of the carriage.

It will be noticed that the inking-carriage enters and leaves the guides on the type-bed only when the inking-table and type-bed are shown in dotted lines, thereby prein line, as

[ venting all danger of jamming or sticking of the inking-carriage in the guides.

WV is the paper roll, mounted upon the bracket and passing over the idler-rolls Zin contact with the platens L L to the folder. Not shown.)

X is a roll from which the offset-sheet passes over the idler-pulleys m to the empty roll n, where the offset-sheet is wound up again. These rolls are preferably secured in notches cut in the cross-rods 0, so that when the paper has run off one roll it can be rolled along the rods 0 to the bearings in the opposite end and the same offset-sheet again fed through. It will thus be seen that the paper as fed through is printed first on one side and then on the other, the offset-sheet being used to prevent the smudging of the paper upon the side already printed upon.
