Beit known that I, JULIUS WE IMAR, a sub is employed for the several operating parts of ject of the Emperor of Germany, residing at the machine,and the said frameworkis formed Otfenbach-on-the-Main, Germany, have inor provided longitudinally with guide-rails 5 vented certain new and useful Improvements 2 2, in which the supporting guidepulleys 3 55 in Printing-Presses, (for which Letters Pat- 3 for the reciprocating carriage y are received. ent have been granted in England, No. 9,213, The said carriage is formed or provided on its dated May 9, 1894; in France, No. 238,442, `under side with suitable guide-tlanges 5 5, dated May 11, 1894; in Belgium, No. 110,109, which are adapted to the said pulleys 3, and

The said pinion also engages and construction, arrangement, and combinations moves over a stationary 113,01; n, and if, will zo of parts as will hereinafter be more particuthus be seen in what manner the said carriage 7o larly described. y is operated or reciprocated back and forth.

The invention has reference more particu To explain the operation, it may be stated, larly to what are known as rapid printingbrieiiy, that the pinion t imparts motion to the presses, and it has for its object to increase enlarged toothed wheel fr, and which latter,

25 the working capacity of the press and to simbeing eccentrically connected to the rod w, 75 plify the construction and arrangementof the causes the said rod to reciprocate, and which impression-cylinder, as well as the devices or action4 moves or reciprocates the carriage in connections through the medium of which an obvious manner. The said carriage by said cylinder is started and stopped at the being supported upon the guide-pulleys 3 3 3o proper intervals. is maintained in a straight line during the 8o The invention also has suc-h other objects movements thereof. The said carriage fy rein view as will hereinafter more fully appear ceives and supports a table y', upon which when taken in connection with the accompathe engraved stone or type-form is suitably nying drawings, in which" laid for the purpose of obtaining impressions 3 5 Figure 1 is a side elevation of a printing therefrom, and it is of .course obvious that 85 `press having my improvements embodied in the said table and type-form is reciprocated connection therewith. Fig. 2 isa vertical or carried back and forth with the carriage transverse sectional view taken on `the line as the latter is operated.

x a: of Fig. 1. Fig.` 3 is a detached side View While Ihave herein described in detail the 4o in detail of the devices which are thrown into particular means by which the carriage is op- 9o and out of engagement with the cam-groove, erated, it is apparent that any suitable conthrough the medium of which the impressionventional devices might be employed to the cylinder is actuated orstarted. Fig. 4 is a same end; but as I have found the present top or plan view of Fig. 3 in part horizontal arrangement exceedingly simple and reliable 45 section. J I prefer the employment of the same in use. 95

My invention is capable of being practiced The impressioncylinder a is suitably supin several different ways; but preferably I ported in bearings at the opposite sides of the resort to the use or employment of the de- `framework of the machine, and in order to vices substantially such asI have herein illusleave only as much surface as is required to 5o trated. Thus in the accompanying drawings obtain an impression I reduce the periphery zoe of said roller or cut out a portion of the body thereof, which construction also permits of the satisfactory operation of suitable sheetgripping devices which are employed, but Which, however, are not herein shown or described. In lieu of any special form of such. latter devices, any of the well-known or conventional forms of gripping devices are equally adapted to be used with my construction of impression-cylinder. The said im-v pression-cylinder a has attached or secured thereto at one end a toothed wheel or pinion Z), and the said wheel is provided with a steel tooth Z, the normal position of which coincides with a vertical line drawn through the axis of the impression-cylinder and the func* tion or purpose of which tooth will be more specifically referred to hereinafter.

Suitably supported in bearings at a point beneath the yimpression-cylinder and at that side of the machine at which the toothed wheelZJ-is located is a suitable short spindle or shaft o", upon which is held or supported, in a manner to turn, a vertically-disposed lever c, the upper end of the said lever being notched at e', so as to be engaged by the tooth Z, as will be explained.- The said lever c is formed or provided on its inner side at or near each end thereof with a lug or projection e2, which lugs or .projections fit into or enter corresponding notches or openings c3, formed at corresponding` points in the vertically-disposed arms d of a three-armed lever CZ, thethird arm of said lever CZ being indicated at Z3 and projecting forwardly and upwardl y at an angle of about forty-live degrees, (450.-) rlfhe said lever (Zis formed with or attachedto a hub D, which is movable vlongitudinally on'the shaft or spindle r, and the said lhub is provided with a groove D', in which is received the pins or lugs s, carried by the forked or bifurcated end f of a swinginglever f', which is providedwith a hub f2 and has its bearing or point of oscillation on a stud or pin f3, suitably secured in place upon the framework. The opposite end of said swinging or-oscillating lever f is provided with a projection g3, -which enters the cam,-groove g4 of a cam or eccentric g, which latterhas its bearing` upon `the shaft g,\the same as does-the enlarged toothed wheel a', hereinbefore referred to. The arm Z3 of the lever CZ is provided at its end with a pin a', which supports a roller a2 on each side of said lever-arm, and accordingly as the levers c and cZ arein or out of the proper positions toactuate and stop the.impression-cylinder one of said rollers CL2 will be in engagement with a cam-groove e and -the other will be received bya slot ina bridge d5.

The construction and relation which the le` versc and CZ bear to each other is such that they are never disengaged from each other butare always in a position to operate conjointly or in unison, as will appear. The camgroove referred to and shown is formed in a pendent portion constituting practically a herein.

part ofthe carriage y, and the general shape of the same is such that when-the carriage is at its rearmost position the horizontal or straight portions thereof will be on opposite sides of the said levers c and CZ. Also formed with the said carriage on its upper edge at the side corresponding to the toothed wheel b is a rack b2, which engages said toothed wheel immediately the latter has been actuated or started, as about to be explained. Vhen the carriage y has arrived at the end of its return stroke, or when the same is in the position indicated at Fig. l and is about to be sent forward again, t-he eccentric g, acting upon the lever f', moves the three-armed lever CZ into such position that the inner one of the rollers a2, carried at the end of the arm Z3 thereof, will be carried into the forward end of the cam-groove e, and then as the carriage starts forward through the medium of the operating mechanism described, the said lever CZ will be brought forward on its axis 1', the arm Z3 being first thrown downward by reason of the shape and direction of the cam-groove, and the lever e being also rocked forward by virtue of the described connection of this lever with the said lever d. As the carriage g/ continues to move forward the said levers e and (Z will be gradually restored to their original position by virtue of the intermediate inclined portion E of the cam-groove, so that by the time the carriage hasreached thc limit of its forward movement-and the roller a2 of the third arm of the lever (Z is carried into the straight portion E' of the cam-groove the said lever (Z will be in readiness to be moved or shifted on the spindle r, so as to be carried out of engagement with the camgroove. The engagement is broken at about the ltime the carriage reaches the end of its'forward movement, and on the return movement of the carriage the cam-groove has no effect uponthe levers. lVhen -the arm d3 of the llever CZ is thrown downward by the operation above described, the connection of the upper end of the lever c with the tooth Z of the toothed wheel Z) gives to the impressionroller an impetus or initial start, and said wheel Z) becomes im mediately engaged by the upper rack b2, and the impression-cylinder is carried around and over the stone or type-surface, in an obvious manner.

l may employ any suitable devices for feeding the sheets to be printed upon 'to the impression-cylinder, as well as any preferred form of devices for gripping or taking'hold of the sheets and holding them in position while being carried around by the impressioncylinder; but I have preferably omitted any such devices herein. In like manner l may employ any preferred or conventional form of inking rollers or devices, together with dis` -tributing and moistening devices; but have also purposely omitted to show such devices action of the impression-roller is obtained through the medium of devices which are ex- It will be observed that the desired l roo ceedingly simple in construction and arrangement, and it will also be seen that the action of said devices is at all times perfectly reliable.

Located above the impression-cylinder a a set of delivery devices for the sheets is employed; but inasmuch as the same forms no part of my present invention, and could be substituted for any of the approved conventional forms of such devices, no specific mention thereto need herein be made.

Without limiting myself to the precise details of construction and arrangement shown and described, I claim as my invention- 1. In a printing-press the combination with the impression-roller having the pinion provided with the lateral tooth the lever c in movable 'connection with said tooth, the threearmed lever d movably connected with said lever c, a reciprocating carriage having a rack engaging the pinion of the cylinder and provided vvith a cam-groove, and means for shifting the said lever d into and out of engagement with said groove at the completion of the forward and return movements of said carriage respectively, substantially as described.

In a printing-press the combination of the reduced impression -cylinder provided with the pinion having the lateral tooth, the lever c vertically disposed and in movable connection with said tooth, the lever d in movable connection with said lever c and having the forwardly-proj ectin g inclined arm carrying a roller, a reciprocating carriage having a rack engaging the pinion and provided with a cam-groove, and means for shifting the lever d into engagement with said cam-groove at the limit of each return movement of the carriage, substantially as described.
