To all whom it may concern:

Be it known that I, BENJAMIN W. MORGAN, a citizen ofthe United States, residing at Atlanta, in the county of `Fulton and State of Georgia, have invented a new and useful Printing-Press, ofI which .the following is a specification.

This invention relates to that class of printing presses having a bed and a cylind'er coacting therewith. The object is to provide a novel presswherein theelements and combination of elements are extremely'simple and the necessary cycle of operationsis effectively produced4 and properly maintained, the .simplicity ofthe structure making the cost of manufacture ycomparativelychine. Fig. 2 is a similar view of the opposite side of l theimachine. Fig. 3 is a vertical longitudinal sectional view. Figl 4 is a detail cross sectional view through the operating means for the bed. Fig. 5 is a detail sectional view of the clutch member of the 'cylinder rotating means. Fig. 6 is a detail perspective View of one ofthe gages vand a portion of the paper-clamping device. Fig. 7 is a detail view showing the combinedoperating means for the paper-clamping device. Fig. 8 is a rear elevation of the cylinder and paperI-operating mechanism coacting therewith. Fig. 9 is a sectional view showing the fly-frame actuating mechanism. Fig. 10 is a cross Isectional view showing the driving and counter shafts and the various devices carried by the. latter. Fig. 11 is a vplan viewof the actuating mechanism for the cylinder elevating and lowering means. Fig. 12 is a detail sectional view taken on the line 12--12 of Fig. 11. Fig. 13 is a detail sectional view taken on the line 1313 of Fig. 5.

Similar reference numerals designate corresponding parts in all the figures of the drawings. I

In the ernbodimentnillustrated, a suitable supporting -frame 8 is employed, in the upper portion of which is mounted a horizontal longitudinally reciprocating bed 9, Carried upon rollers 10. This bed is provided-on its under side with a longitudinally disposed rack l1 and located beneath the same is a longitudinal bar 12, constituting, iI`1 effect, a part'of the'supporting frame. The bar 12 has a portion `between its'ends divided, as shown at 13,'to form spaced tracks, the upper edges of which have racks 14. A gear wheel 15 of comparatively large diameter meshes with the rack 11 of the b'ed and extends between the tracks 13. On the opposite sides of and secured to the gear wheel 15 areother gear wheels 16'of less diameter than the same and engaging the Specification of Letters Patent. Application filed January 12, 1905..

racks 14. "It will, therefore, lie evident that if these gears are reciprocated, the tralvel of the smaller gear 'wheels will be comparaively small, while the larger gear wheels will cause the .bed to move a relatively great distance. The means effecting the movement of the gear wheels, and consequently ofthe bed, is as follows: v

A drivingl shaft 17 is mounted'transversely inthe frameand carries a balancev or fly-wheel 18. This shaft may be 'operated by any suitable power, as will be clearly apparent, but, in the present instance, the press isto be run by hand, and therefore,`a handle'19 is shown, attached to said balance wheel., The 4driving,shaft 17 carries alpinion 20, meshing with a `large gear 21, secured to a counter shaft 22, also journaled transversely in the frame. The gear wheel 2l consti- 70 tutes, furthermore, a crank wheel, one of the spokes thereof carrying a crank pin23, that. can be secured in any of a line of openings 24, formed in said spoke. To the crank pin 23 is pivotall'yl secured a pitman rod y l25, which rod is connected to the common axle 26 of ',75 L j the gear wheels 15 and 16.A Thus, it will be seen that.; when motion is imparted to the main driving shaftl'17, the gear and crank wheel 21 will be revolved, thereby reciprocating the gear wheels 15 and 16 and effecting the' reciprocation o' the bed. Moreover, it will be 80 noted that the bed will operate slowly asiit reaches the l, ends of its movement, so that the shock of the reversal of such movement will be'redc'ed to a minimum.

Coacting with the bedl and located over the same is a rotatable cylinder 27, journaled in the upper ends of vertical standards, each comprising sections 28 and 29. The-upper sections 28 arevprovided with enlarge ments 30, constituting bearings for gudgeonsl 31 of the cylinder, while the lower sections 29 are provided carried by a rock shaft 34, journaled transversely inv (the supporting frame 10. The sectionsare connected at their adjacent ends by adjusting screws 35, threaded into said sections and having jam nuts.3,6, adapted Ato bear against the ends of the same to prevent the acci- '95 lmovenientof the link. 'The head lis provided on opposi'te sides ofthe slot withl'projections 37p, the rear faces of which are inclinedthe front facesbeing pr`efthe cylinder.

erably andat iightanglesto the adjacent faces of v "the'head These projections are disposed in the path of movement of a pin-40, carried by a disk 4l, adjustably secured on the counter shaft byvmeans'of a set by means of a coiled spring 43, interposed between the head and the adjacent side of the framexlt will thus be apparent that, during the reciprocation of the bed, the revolution of the crank disk' 41 will cause this crank pin 40 to alternately engage the opposite square shoulders of the projections 37,'thereby moving the'link in oppositel directions, consequently, moving the rock shaft and elevating and depressing The movement of the` cylinder is, 0f course, timed to the action of the bed, so that when said bed is'm'oving in one direction, the cylinder is depressed, 'and in coacting relation with the same,

'and when moving in anoppos'ite direction, said cylinder is elevated so as to'be entirely free of such bed. lf a reverse movement of the mechanism should take place, the pin 40 will successively ride over the inclined sides of the projections, and thus forcing the head 37a away from. the diskv and againstl the tension of the coiled spring 43 will .not effect the movement of the link and all danger of injury or breakage to the parts will b e avoided. The throw-off movement of the cylinder can also beaecomplished at any time through-the medium of a foot treadle lever pvoted at one Vend to the frame and having a link connection 41a with an aim 42, that is attached to the rock shaft 34.

In order to secure an initial rotation of the cylinder' prior to its operation over the forms on the bed, said cylinder is driven directly from the driving-mechanism so that a rotary movement of the same is secured'.

independently of the bed. .As shown in Figs. l, 5 and '13, the main or drive shaft 17 carries at itsouter end,y

f and preferably just inside the balance wheel 18, a pulengages said cylinder.

ley 44, which pulley has a clutch connection with the shaft through said balance wheel. To this end, the.

said wheel is provided in the face adjacent to the halance wheel with a recess 45, having an inclined bottom and terminating at one end inan abrupt shoulder. In a socket in the hub of the fly-wheel is slidably mounted a pin 46, yieldingly urged outwardly against' the pulley 44 by means of a spring 47, located behind said pin. This pin is arranged to engage in the recess 45 and thus turn the pulley 44. A belt 48, passing about the pulley 44, also extends around a pulley 49, secured to one of the gudgeons 3], of the cylinder. The speed of rotation given to the cylinder by the belt and pulley connection with the driving shaft is synehronous with the motion pf the bed when the `The purpose of this belt drive is to secure the movement of the cylinder independently of the bed, so that the paper may be carried and fed around to thc proper position to take the forms without the necessity of cushions or bearings in ad- Vance of the forms to effect a preliminary rotation of the cylinder.

In operation, the pulley 44, being actuated by the drive shaft` f7, revolves the cylinder wih a steady continuous motion until the forms reach the cylinder on the impression stroke, wnerenprn; the movement of the cylinder is accelerated synr-ln'onously with the moti Jn of the bed, the policy of the cylinder therebeing urged towards said disk Lyric esame upon driving the pulley ofthe main shaft and causing it to overrun the motion of said main shaft. This overrunning is permitted by the pin clutch between the fly wheel and the adjacent pulley. Said pulley being now operated at a greater rate than the fiy wheel, the pin lwill ride up'the inclined bottom of the recess 45 and will frictionally bear against the adjacent face of the pulley. When the forms leave the cylinder, said cylinder stops momentarily of until the pin carried by the hub reaches-the recess, and, riding down in said recess, abuts against the terminal shoulder thereof, whereupon the normal motion is again imparted to the pulley, and consequently to the cylinder. The means for feeding the paper to the cylinder is as follows: AnA inclined feed table 50 is mounted upon the frame 8 above thebed, and has its lower end'disposed directly over the cylinder. In spaced relation to said lower end are'located the upper ends of guide strips 51, extending in rear of and beneath the cylinder, and preferably slightly spaced from the same. These guide strips are secured to collars 52, which, in turn, are supported on a rock shaft 53, the rock shaft havingv a rotary movement in said collars. ends of the guide strips are rigidly attached bar 54, secured beneath the cylinder, as 3. The upper ends of the strips 5l are turned, as shown in Fig. 6, and have a gages, each consisting of a pivot portion 5G, journaled in said bearing and having at one end a downturned stop finger 57, movable into and out of coactiou with the cylinder.' The opposite end of the pivot portion is provided with a crank 58, that extends outwardly and beneath an arm 59, rigidly afiixed to the rock shaft 53, by means of a set screw G0, which permits the adjustment of said arm on the rock shaft. The free ends of the arms 59 (one being located at each end of the rock shaft 53) carry a paper-clamping device in the form of a roller 6l, journaled to and between said arms and movable into and out of coaction with the cylinder when the arms are swung. This roller is groovcd spirally, so that it spreads wrinkles out of the paper passing thereunder. A bel'l crank lever G2 is jonrnaled on one side of the frame and one arm thereof has a link connection y63 with one of the arms 59. The other ol" horizontal arm ofthe bell cranklever G2 extends over a cam 64, mounted on the counter shaft 22, and has a pivoted dog 64, that rides uponthe active or peripheral surface of said cam. lA weight (i5 may also be adjustably mounted on thisvarni of the lever in order to secure the proper action of the parts, as hereinafter described. i

The operation of the feediiu,r means, above described, may be briefly outlined as follows: During the movements of the bed and cylinder, the cam (i4 is, of course,

to a cross shown in Fig. preferably upbearing for rotated.` Consequently, at predeterminod intervals` the horizontal arm of the bell crank lever is raised by said cam and the arms are thus swung. upwardly, so that the roller (il is carried away from the cylinder. As the stop fingers 57 of the gages are heavier than the cranks, it will therefore be evident that said stop fingers will drop into coaciion with the cylinder and lightly rest against the saine. Consequently, if paper is now fed from the table 5U, it will pass freely under The lower .llO

the roller (il and abut against thel stop lingers of the 0 gages. As the movement of the cam continues, the

dog '64 of the horizontal -arm of the bell crank lever will reach the inner part oi said cam so as to permit the arm to d rop. The result is that the clamping roller 61 will move downwardly into coaction with the cylinder, clamping the paper thereon, so that the rotation of said cylinder will cause the paper to be fed downwardly and properly to the forms of the bed. The downward movement of the arms 59 will cause a simultaneous movement on the part of the crank 58 of the gages, so

that the stop finger will be raised to permit the free passage of the paper therebeneath. It'will, of course, be understood that these movements are also properly timed with respect'to the operation loi the bed and cylinder'.

The delivery mechanism will now be described: Located beneath the feed table and above the path yoi movement of the bed 9 are sets of upper and lower endless tapes 66'and 67. The upper of these tapes, designated 66, pass around the cylinder 27 andare driven thereby, while they also run around a roller 68, located beneath the upperl end of the table. The lower tapes 67 of the sets pass about rollers 69 and 70, the rear roller 70 being disposed directly adjacent to the cylinder 27, and just in advance of the lower guide strips 51. This roller 70 has attached to it a pulley 71,

located-at one side of thc machine and in engagement with the driving belt 48 of the cylinder. Consequently, it will be apparent that these tapes all move synchronously with the cylinder at all times and without regard to the variableness oi the speed of its rotation'.

At 'one endof the frame and directly beneath the delivery portions of the tapes 66 and 67 is journaled a fly-frame that ordinarily maintains an upright position. This ily-frame consists of a rock shaft or bar 72, having the usual fingers 73, the upper ends oi which are located contiguous to the tapes 67. The rock bar 72 has a bracket 74, to which is pivoted the lower end of a link 75, the upper end of said link being pivotally connected to 'another link 76, swingingly suspended from its upper end and having attached to its lower end a spring 77, said spring being connected to the rock bar 72, through the medium of an ear 78, carried by said bar. A roller '79, journaled upon the suspended link 76, rides upon the peripheryroi a cam 80, .which cam is carried by the counter shaft 22 and is constructed so that, during the greater part ol' its rotation, the flyirame will be held in elevated position against. the tension of the spring 77; but, at a certain point in its travel, the roller 79 is permitted to move inwardly toward the shaft, thus allowing the spring 77 to operate and swing the ily-frame downwardly, as shown in Fig. 9. This movement is, oicourse, timed to the other mechanism, so that the operation of the ily-frame will take place just as a printedi sheet is delivered from the tapes.

Inking mechanism, operated in a peculiar manner by certain of the elements already described, is also employed. As shown, this inking mechanism com` prises spaced inking rolls 8l, over and in engagement with which is located a distributing roll o2. A lountain 83 of'any desired construction is provided with a l'eed roll 84, and a transmitting roll 85 operates between the feed roll 84 and the distributing roll 82. The said feed roll is -given a step by step movement, and lor this purpose, at one end of the same is secured a ratchet Wheel 86, engaged bya dog 87 carried by an oscillating llever 88. To the lever is connected a link 89, that is also pivotally connected to the link 37, already described. This link 37 has a longitudinal reciprocatory motion, and consequently the link 89 will be given a similar movement. The lever 87 is thus oscillated and the dog successively engaging the teeth of the ratchet wheel 86, will move the same,` The transmitting roller 85 is journaled in arms 90, which are pivoted to the arms 59. As the arms59 have a swinging movement, it will be apparent that the transmitting roller will be moved from the feeding roll 84 to the distributing roll 82.

Assuming the press driven by any suitable power, it will be evident that when the bed reaches the limit of its lmovement; in one direction, the cylinder will be elevated and simultaneously with this elevation, the

clamping roll 6l will be moved away from said cylinder while the gages will, as a consequence, drop into coaction therewith. Paper is thereupon fed beneath the clamping roll Glpand against the gages. As the bed moves to the opposite limit of its movement, `the clamping roll is depressed, the gages are elevated, and the paper is thereupon fed downwardly, so that it will be in proper position to pass beneath the cylinder as the form returns and said cylinder is depressed to printing position. As said cylinder takes the form, it will-also take the faster motion thereof, and the papervwill be delivered by the guides between the coacting stretches ofthe tapes 66 and 67. These tapes will deliver it over the iy, which, at the proper instant, is operated to remove the sheet from the machine. Simultaneously with the elevation and depression of the cylinder is the action of the iced roll of the inking fountain, and s imultaneously with the movement of the clamping roll- 6l is the movement ol' the transmitting roll 85 of ythe inking mechanism. lt will be apparent that the mechanism employed for securing this cycle of operations is comparatively simple and that said elements may be properly adjusted so that the proper iro-operation can at all times be secured.

From the foregoing it is thought that the construction, operation, and manyl advantages of the herein described invention will be apparent to those skilled in the art, without further description` and it will be uuderstood that various changes in the size, shape, proportion, and minor details oi construction may be rcsorted to without departing from the spirit 'or sacrificing any of the advantages of the invention.
