Application filed April 22,

To all zit/m it may concern:-

be it known that we, SWAN SMITH and Oscivn ll". llAll'MERQUlS'l, citizens of the United States, residing in Ramsey county, in the State of iv'linnesota, have invented new and useful Improvements in Printing-Presses, of which the following is a specification.

Our invention relates to printing presses of the cylinder ie.

its object is provide a simple, durable and eflicient pr: s having a reciprocating impression cylinder and a movable bed adapted to coact with the impression cylinder.

A. further object is to provide in a printing press of this class means for manually dropping the bed and discontinuing the operation of the inking mechanism irrespective of the movement or position of the impressicn cylinder.

A further object is to provide means for insuring a perfect register-between the impression cylinder and the bed.

In the drawings Figure 1 is a side elevation of our improved press; Fig. 2 is an end elevation. of the same with the feeding platform removed; Fig. 3 is a sectional view taken on the-line of Fig. 2 and Fig. 1- is a detail sectional view showing the cylinder and bed with its operating mechanism.

Referring to the drawings, we have used the reference numeral 10 to indicate the press frame, 11 the impression cylinder, 12 the bed, 13 the feeding platform and 1a the delivery platform.

The in'ipression cylinder 11 is rotated continuoi'isly and is adapted to move backward and forward above the bed 12 from the feeding platform 13, where it rests to receive a sheet of paper to the delivery platform 14, where it again rests to dischar e the printed sheet. The carriage members 15 are movable on the slides 16 of the frame 10 and form bearings in which the ends of the cylinder supporting shaft 11 are journaled. The cam shaft 17 in the frame 10 is provided with a double faced cam 18 and is operatively connected through. the gear wheels 19 and "20 with the power pulley 21. A segment provided at each end with a cam roller 23, is fixed to the rock shaft 24: on he frame 10. Each face of the double cam 4' 1- A 1 Patch ten Jan. ll, Natal.

18 engages a roller 23 and when rotated rocks the shaft backward and forward. A pair of upwardly extended levers are fixed at one end to the rock shaft 24:, each lever being pivotally attached at its upper end to a connecting rod 25 which is also pivotally attached to one of the carriage members 15. Thefaces of the cam 18 are angularly spaced apart, each comprising a neutral low portion, an active outwardly extending part, a neutral high portion and an inwardly extending part. The active portions cause opposite strokes of the cylinder 11 and the neutral portions retain said cylinder for a predetermined interval at the end of each stroke.

The cam shaft 17, counter shaft 27 and shaft 28 are respectively provided with meshing spur gears 29, 30, and 31 and the shaft 33, journaled in the frame 10, is driven. by the shaft 28 through the beveled gear wheels 3% and 35 located respectively on the shafts 28 and The cylinder supporting shaft 11 is driven continuously from said shaft 33 by means of the spiral gears 36 and 37. The gear is fixed on the shaft 11 and its meshing gear 37 is feathered on the shaft Said gear 37 is retained in mesh with its companion gear 36 and is shifted on the shaft 33 by the arms 38 of the bracket39 on the carriage member 15 adjacent to. said shaft 33.

To insure perfect registry between the inipression cylinder 11 and the type form in the bed wehave fitted the cylinder 11 with a gear l0 and the bed 12 with a rack. at]. adapted to mesh with said gear when the cylinder 11 is in contact with the form.

The bed 12 slidable on its posts 12 of the frame 10 is normally elevated when the cylinder 11 moves forward, thus causing said cylinder to bear against the form contained in said bed and is lowered to prevent contact between said form and cylinder as the latter moves back. Slidable journal boxes or bear ings beneath the bed 12 receive the eccentric shafts 43 which are journaled at their ends in frame 10. is provided. with an arm said arms be ing connected by a link ii? to synchronize the movement between. said shafts. The lever l6 is loosely mounted at one end on Each of these shafts one of the shafts 43 and is provided with a curved slot 47 to receive the bolt 48 by means of which said lever is .adjustably secured to one of thearms 44. The free end of the lever 46 is connected by the link 46 to the free end of the cam lever 49, which is pivotally mounted at its other end on the frame 10. This lever is provided with a cam roller 50 arranged in engagement with the inside cam 51 on the counter shaft 27, and is intermittently oscillated by said cam. Said lever 49 operates through the link 46, lever 46 and arms 44 to rock the eccentric shafts '43, thuselevating the bed 12 on the forward stroke of the cylinder and lowering it on the return stroke of said cylinder.

The shaft 28'is provided with an inking roller 52. This roller is supplied with ink from the ductor roller 53, which gathers its supply from the fountain roller 54. Ink distributing rollers 55 on' the frame 10 are provided for said roller 52. The form rollers 56 on the carriage members 15 contact with the roller 52 at the end of their forward stroke to receive a supply of ink therefrom. Ve arrange and operate the ductor and fountain rollers as follows: The ductor roller 53 is mounted in a pairof arms 57 extending from the shaft 58 j ournaled in the frame 10. The lever 59 on thisshaft is pivw otally connected through the yoke 60 with the eccentric stud 61 on the beveled gear Wheel 34 and is operated thereby to swing' municated through said link, lever and.

ratchet to rotate the fountain roller 54 and supply the same with ink.

During the operation of a printing press it is often desirable to prevent contact between the form andimpression cylinder during one or more strokes of the latter, and 7 it is then of course desirable to discontinue the action of the inking mechamsm. WVe

- have provided the following mechanism whereby the bed may be instantly lowered and the inking operation automatically discontinued. The free end of the lever 46 on one of the shafts 43 isprovided with the slideway 69 terminating at one end in the socket 70. The connection between the link 46 v and this lever consists of a pin 71 in said link adapted to rest in said socket 70. In the normal operation of the press this pin is retained in said socket and the cam lever 49 rocks the eccentric shafts 43 through the link 46, lever 46 and arms 44 as above described. o havesupplied the guide bar 72-with a pivotal and slidable mounting at one end on the frame 10 and have arranged the bell crank '73 in operative connection with said bar and the foot lever 74 on said frame. A slight movement of this lever 74 raises the guide bar which removes the pin 71 from the socket 70. The displacement of this pinchanges the pivotal connection between the lever-46and the link 46 to a slidable one andpermits the spring 75 between the bed 12 and link 45 to act and move the arms 44 to position lowering the bed regardless of the position or operation of the cam lever 49. In shifting this guide bar 72 to position releasing the pin 71 from its socket 70, said bar is also moved forward and extended into the path of the arm 76 on the shaft 58 to prevent the rotation of said shaft and the engagement of the ductor roller 53 with the fountain roller 54. As above described, the ductor roller is thus swung from the fountain roller 54.to the inking roller 52 by the connecting mechanism between the shaft 28 and the beveled gear-Wheel 34, and is then returned by thespring 63. The guide bar '72 prevents the movement of the shaft 58 when turned, by the action of said spring. .WVe have provided the arm 76 with a spring dog 77 movable in one direction. This resilient dog is intended to prevent damage to the guide.

bar 72 in case said bar should be extended into the path of the arm 76, as the ductor roller 53 passes from the fountain roller 54 to the inking roller 'Means are also pres cut for receiving sheets of paper from the cylinder 11 and moving the same to. the delivery platform 14. The rock shaft '7 8 is supported on the frame 10 and provided witha lever 79 which is supplied with a connecting rod 80 attached to the spur gear 31 on theshaft 28. Swinging arms 81 fixed on this shaft, carry rods 82 and 83 adjacent to each other. The rod 82 is adjustably secured in said arms8'1 while the second rod 83 is loosely mounted therein. The rods 82 and 83 are respectively provided with a plurality of co-acting jaws 84 and 85 and the upper rod 83 is also provided with a spring actuated roller arm 86 adapted to yieldingly secure said rod in position and normally hold the pairs ofjaw s together. The arms 81 are oscillated backward and forward over the delivery platform. At the end of. their backward stroke the roller arm 86 engages the cam surface 87, and, the jaws 85 are opened to receive a sheet of paper as the same is stripped from the cylinpler by the fingers 88. arms 81 the roller arm 86 is disengaged from the cam surface 87 and the jaws 84 and 85. grip and carry the sheet forward over the delivery platform.
