SPECIFICATION forming part of Letters Patent No, 580,505, dated December 11, 1894.

Application tied November 15,1893. serial No. 491,014. (No man.)

To all whom it may concern:

Be it known that we, RICHARD CLARK and LOUIS M. OROM, citizens ofthe United States, residing at Warsaw, in the county of Coshocton and State of Ohio, have invented a new and useful Printing-Press, of which the following is a specification. i Our invention relates to improvements in printing presses, and to that particular* class thereof employing a stationary type-bedand a traveling impression cylinder arranged thereover.

The objects of our invention areto provide a press of of the above class, the samebeing so arranged as to readily receive and automatically emit or discharge the paper after-,printing and whose capacity for rapid printingis increased. Various other objects and advantages of the invention Will appear in the following description and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawingsz-Figure l is a plan view of a press embodyingjourlinvention. Fig. 2 is a side elevation thereof;` jfFig. 3 is a vertical longitudinal centralsectionalview. Fig. 4 is a transverse vertical sectional- View. Fig. 5 is `an enlarged view in crosssection of the revolving cylinder. Fig. 6 is an enlarged detail in perspective of the carriage for conveying the cylinder.

Like numerals of reference indicate like parts in all the iigures of the drawings.

In the practice of our invention we employ any suitable bed-frame. In the present instance, however, We have illustrated one simple form thereof. In the construction shown We employ a pair of lower basesills 1, from which rise standards 2 that support the longitudinally disposed upper sills 3, the sides of the vframe being connected by suitable crossbars or beams 4. The sills 3 constitute a track and are provided at their outer sides with cleats or Iianges 5, Whose upper edges are above the sills to retain the cylinder carrying carriage, hereinafter described, thereon. Arranged upon the frame thus constructed isthe cylinder carrying carriage, and

i1 the same consists of opposite sides 6, which are reduced toward their ends, and isof a width to fit within the cleats 5. Rollers 7 are located at the four corners of the carriage andare designed to move upon the track,

cheap and simpleconstruction and which as before stated, is formed by the upper sills 3. `The sides `6 are at their centers provided with bearings 8, in which are jour-` naled the ends of a transverseshaft 9 which accommodates and passes through the im-` its surface covered with any desired covering,

as shown. A l Standards 1.1 rise from `the sides 6 ofthe cylinder carrying frame, and at their upper ends are provided with slotted lugs 12 in which are loosely mounted the opposite eX- tremities of the axis `13 of a paper-grasping roll 14. Inasmnch as the lugs 12 are slotted, l l it Willbe seen that the roll 14 mayraise and lower, but ordinarily runs in surface contact with thecylinder 10 by which it is revolved. `At opposite sides of the cylinderwe mount `pression cylinder l0. This cylinder 10 has upon the sides 6 the transverse guard-bars 15,

and the same are provided `at intervals with yielding substantially` triangular` guard-fingers 16, which are curved at their inner sides to embrace the opposite sides of the cylinder, as best shown inFigs. 5 and 6. Below these l guard-bars in bearings 17 ateach sideof the cylinder l0, We journal loosely a pair of inking-rolls 18, `whose lowerfsurfaces are-in .the same plane as that of the cylinder 10. Above `the inkfrolls we journal at each side of the cylinder 10, in bearings 19, the axles of a gnide-roll 20.

Hinged leaves 21 are arranged'upon the ends of the cylinder-carrying frame, and are disposed normally inward toward the cylinder thereof, being supported at their inner ,l endsby cross bars 22 which span the frame at each side of the cylinder, and complete iiies on which the printed sheets are allowed to accumulate.

Opposite superimposed frames 23 are horizontally disposed above the opposite ends of the framework of the press, and these frames support inclined feed-tables 24 which decline from their outer ends toward their inner endsl and have extended in front of such ends the4 substantially horizontal extensions or plates 24a. Each feedtable is provided ,at opposite sides or ends with arms 25 that are inwardly disposed and connected at their inner ends and have upturned cam or hook-shaped ends 26. Each frame 23 comprises in its make-up a cross-bar 27, and to each cross-bar is attache'd a pair of coiled springs 28. Pairs of IOO tapes 29 are connected at their extremities to the inner ends of these coiled-springs, pass over and around the rolls 20, and are connected thereto. The rolls 20 are connected by intermediate guidetapes 30 which are wound reversely thereon so that the rolls revolving in the same direction will cause the tapes to wind upon one of them and unwind from its companion.

At the center of the framework we locate in the cross-bars 4 of the bed-frame vertical adjusting-screws 31 whose lower ends are so shaped as to receive a wrench. The upper ends of these screws are swiveled to the under side of the type-bed 32. At each side of the type-bed and supported bycleats 33 We locate inking-tables 34 which are in a plane with the type-bed. Paper-receiving tables 35 occupy the ends of the framework below the frames 23.

Any means may be .provided for reciprocating the cylinder-carrying carriage over the type-bed. In the present instance, however, We have illustrated one form which we will proceed to describe. We locate in transversely opposite pairs of bearings 36 crankshafts 37, connecting the two by means of an intermediate rod 38a. Both ends of one of the crank-shafts 37 are extended to form rock-arms 38, which by means of links 39, shown in Figs. 1 and 2, are loosely connected with the extended ends of the shaft 9 of the impression cylinder. The remaining shaft 36 has one or both of its ends extended, and is designed to serve as a handle 39L where the press is operated by hand, or to be connected with any suitable motor for vibrating the same.

A pair of hangers 40 depend from the opposite sides of each of the feed-tables, and being provided with bearings accommodate a transverse shaft 42 located under each of said tables. The intermediate portion of each shaft is upwardly cranked,as at 43, and passes through an elongated slot 44 to a point above the base 23 of each feed-table. One of the outer ends of each shaft 42 declines toward the center of the machine forming an arm 45, the extremity of which is inclined or slightly upwardly bent as at 46 and arranged in the path of the journal 9 of the cylinder. The opposite sides of the inclined feed-tables .24 are slotted, as at 47, and in the same there are mounted for movement transversely disposed slide-bars 48, which at their centers are connected to and adapted to be actuated in one direction by the crank portions 43 of the shafts 42. It is to the end of these slide-bars 48 that the arms 25 are connected.

In the operation, the paper is fed by attendants from the inclined feed-tables 24to points over the edges of the extensions 24a. The cylinder-carriage advances toward the projecting paper, and the journal 9 which projects beyond the arm 39 thereof strikes the inclined end 46 of the adjacent arm 45, causing the same to elevate and hence rock the shaft 41. This action of the shaft 4l allows the arms 25 to recede in advance of the approaching cylinder until it has reached the limit of its backward movement. In the meantime, the paper-grasping roll 14 has arrived in contact with the cam ends 26 of said arms 25, so that as will be obvious, the roll 14 iscaused to rise and hence passes over the end of the paper on the plate or table extension 24a. As the carriage recedes the paperroll 14 travels down the cam ends 26 of the arms 25 and engages with the paper, clamping it upon the revolving cylinder. The Weight of the arms 45 is sufficient to return the parts to their normal position.v The cylinder, it will be observed, is revolved in that it runs in contact with the track 3, and the tapes 30 move under the cylinder in the same direction as the travel of the latter, so that the sheet of paper engaged by the papergrasping roll 14 is fed to the fingers of the cylinder and continues under the fingers until it arrives in contact with the guide-tapes, which continue the movement of the paper and carry the same under the cylinder to the opposite side thereof. Of course when the paper arrives under the cylinder it is in contact with the type, so that an impression is made upon one side of the paper. At this point the guide-tapes 30 conduct the paper from under the cylinder and deliver it upon the leaves 21. By this time the carriage is at the opposite en d of the machine, Where the operation described is repeated, and in moving from thispoint to the starting point the second sheet is printed and delivered. At intervals when a number of sheets have accumulated the leaves 21 are reversed and dump the contents upon the tables at the ends of the machine. The inking-rolls, it Will be seen, travel over the ink-tables 34 and serve tosupply the face of the type with the necessary ink. The coiled springs 28 give tension to the tapes 29 and serve to revolve the guiderolls 20, and aid in the operation of the guidetapes 30.

It will thus be seen that we have provided a machine adapted to rapidly print and automatically feed or carry through the press the successive sheets of paper, the said machine being of cheap and simple construction, comprising few parts, and those of simple formation.

We do not limit our invention to the precise details of construction herein shown and described, but hold that we may vary the same to any degree and extent within the knowledge of the skilled mechanic. At this point further attention is directed to the manner of feeding the unprinted sheets from the opposite feed tables to the impression cylinder. It has already been noted that the operator or feeder manipulates the unprinted sheets on the tables 24 so as to bring the edges of the same over or slightly beyond the edges of the table extensions or plates 24., and toward the approaching impression cylinder. When IOO IIO

the impression cylinder approaches the sheet of paper thus positioned, the paper roll `14, engages with the upturned cam or hook shaped ends 26 of the movable arms 25 at that end of the machine, and the shape of these ends willcause the roller 14 to raise above the paper, which is held by the feeder, and to pass to a position over the extensions or plates 24a. .I ust before thishas taken place the arm toward which the cylinder has approached has been lifted by the engagement of one end of the journal 9, therewith, so as to move the upwardly disposed crank portion 43, of the shaft 42 in a direction which relieves the weight of the arm 45from the slide bar 48 connecting one end of the-arms 25, so that there Will-be nothing to interfere with the paper roll 14, carried by the carriage, from pushing the arms 25 in front of the same, as it rises up the cam ends 26, this movement being necessary to carry the paper roll above the sheet of paper and back from the edge thereof.` As the impression cylinder commences to retreat from the feeding table,

which has just been referred to, the paperv roll 14 travels down the cam ends 26 of the arms 25, and rolls `over the sheetV of paper, which will not move until the said roller reaches the edge of the feed table or at least the extension 24a, thereof, at which time the friction of the small roller on the cylinder will cause the paper to be rolled between the roller and cylinder and moved under the guides at one side of the cylinder, until caught by the tapes passing under the cylinder, and since the carriage is during this time moving toward the opposite feed table, an impression will be made on the sheet of paper and the same delivered to one of the ities.

It will of course be understood that when the carriage carrying the impression cylinder leaves one of the tables, the arm 45 at that end will lower, and will of its own weight again project the arms 25 inwardly to dispose the cam ends 26 beyond the inner edge of the table extension or plate.
