PRINTING-PRESS.

To all whom it may concern:

Be it known that I, AUGUSTUS W. VAUGHN,

a citizen of'the United States, residing at Adel, in the county of Dallas and State of Iowa, have invented certain new and useful Improvements in a Printing-Press, of which the following is a specification.

The Objects of my invention are to provide a printing press of simple and durable in position relative to the type asthis printing roller passes over said type. i

A further ob ect.1s to provide a mechanism which will automatically raise the frame over which the printing roller passes when said roller reaches its extreme ou tcr limit of movement and maintain said frame in a raised position While the roller is moved to its point of starting and thus prevent the paper from "being inked on the rear movement of the roller, and further to provide a mechanism for automatically releasing the frame from raised position and allowing it to move to its ing roller whie tical movement. h 1 My nvention consists in certain details 1n its lowered position as the .roller approaches its point of starting.

A- further ob'ect is to provide a ball bearli is designed to be placed on the ends of the shaft upon which the print ing roller is mounted and is designed to engage the lower portions of the frames for maintaining said printing roller, against verthe construction, arrangement and combinationof the various parts of the device,.

whereby the objects contemplated are attained as hereinafter more fully set forth,

pointed out in my claims and illustrated in the accompanying drawings, in whichv Figure l shows'a side elevation of the complete printing press.

The dotted lines in this view show the difierent positions of the mechanism'for raising and lowering the frame upon which the printing roller is mounted and the printing roller at its outer limit of- .movement in dotted lines. Fig. 2 is a cross sectionalview of the ball bearing roller which Specification of Letters Patent.

is mounted on each end of the shaft upon which the printing roller is mounted. This View shows said shaft in cross section also. Fig. 3 shows, in perspective, one end of the printing roller with the ball bearing roller mounted upon the shaft which bears it. Fig. 4 is a detail view of one end of'thcframe of theprinting press and of one side thereof and is a cross section cut through the line 4--4 of Fig. 5. Fig. 5 is a plan view of the complete printing press. Fig. 6 is a cross sectional view of the printing roller and shows in cross section the mechanism for adjusting the paper in position on said roller. This view also shows a portion of one of the frames for holding the printing roller against vertical movement.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the frame of the printing press which comprises four legs and connecting pieces between these legs. Mounted on the frame 10 and extending longitudinally of it are the tracks 11 and 12, each of said tracks having a rack 1.3 mounted thereon and extending longitudinally of them. .T he tracks ll and 12 are pivotally mounted at 14- near the feed ing end of the printing press and are thus mounted to allow the outer end of said tracks to be raised and lowered. The racks-13 are mounted on the outside of the top portion of the tracks 11 and- 12 so as to form a flat sur face inside of the racks u on which rollers hereinafter described are a owed to move as the. printing roller is moved outwardly and inwardl on the racks 1'3. Mounted between t ese tracks 11 and)? and near the central portion ofthenron the frame 10 is the form bed'15 designed to. hold in position. the

forms of type and plate which are to be printed. Firmly attached to the outside portion of each of the tracks 11 and 12 respectively are the frames 16 and 17, said frames being designed to maintain the printing roller ag'ainstvertioal "movement as it moves longitudinally of the rinting frame.

Mounted on each'of-the rac rs 13 is a pinion wheel 18 designed to move longitudinally of said racks. i wheels and firmly attached .to them is the shaft 19 upon which the im ression roll 20 is mounted. This printing r0 ler is of the ordilounted between said pinion nary construction having an opening 21 in its periphery and having the gri pers 22 rotatahly mounted in one side of t ie opening, said grippers being designed to be swung by a gearing to aposition for maintaining the paper firmly relative to the impression roll as shown in Fig. 6 ol' the drawings. A further description of this is not deemed to he necessary as this form of impression roll is common in various printing presses. Rotatahlv mounted on each end of the shaft 19 and adjacent to the pinions 18 are the arms 23, said arms extending inwardly from the impression roll and having the shaft 24 mounted between their inner ends. Mounted between these arms 23 and on the shaft 21 are the flanged wheels 25 and 26 designed to move longitudinally over the inner portions 27 and 28 respectivelv of the tracks 11 and 12 the pinions .18 nove longitudinally of the racks 13.

Extending diagonally across the frame and rotatably mounted lietween the arms 33 and in the supports 36 and 37 which. are attached to said arm is the s ireading roller 36, so constructed that it will not only rotate over the forms which are placed upon the form bed 15 as the impression roll is moved outwardly and inwardly, hutit will also move from the left to the right a slight. distance and from the right to the left so that the ink will he evenly distributed over the forms.

Mounted on each end of the shaft 19 and outside of the pinions lb is a ball or roller bearing .wheel 39 whose outer periphenv is designed to engage the under portion of the frames 16 and 17 as the shaft is moved longitudinally of said frames, the inner portions of the rollers 39 which are adjacent to the shaft 19 are cut away to receive the rollers or balls 40 which act on the interior of said rollers 39, and on the exterior of the shaft 19 as the shaft 19 is moved outwardly and inwardly above the frame It). It will be seen that as the shaft is rotated in one direction above the frame 10, the rollers 3.) will he rotated in the opposite direction as they pass over said frame 10 as they engage the frame 16 and 17, thus rotating the rollers 39 in the same direction as the shaft 19 is rotated.

Mounted on the extreme right end of the shaft 19 is an arm 41 the shaft 19 being rotatable in said arm. Pivotally attached to the inner end of said arm is a second arm 42 which is pivoted at its lower end to the frame 10. ltotatably mounted on the frame 10 and near its inner end is the gear wheel 43. Pivotally attached to the gear wheel 43 and adjacent to the lower end of the arm 42 is an arm 44 designed to swing the arm 42 on the pivot 45, and as the gear wheel 43 is turned. Rotatal ly mounted on the frame 10 and in mesh with the gear wheel 43 is the gear wheel 46 which is capable of being driven by means of the crank 17 or from a ower wheel. As the gear wheel 46 is turner in one direction, the upper end of the arm 42 will be moved to its outer limit of movement and will correspondingly move the impression roll to its outer limit of movement, and as the gear wheel 46 is rotated in the opposite direction, the upper end of the arm, 42 will be moved inwardly and the printing roller will he also moved inwardly. 'lhroughout the entire specification 1 mean by the inner end of the machine that end where the papers to be printed are placed upon the machine.

Extending across the outer end of the frame and through the slots 48 in the tracks 13 is the rod 49 having the arms 50 firmly mounted at each end thereof. At the lower end of each of these arms 50 is a curved slot 51 designed to receive the pins 52 which are on the frame 10. As the upper ends of the arms 50 are at their inner limit of movement, the pins 52 will be at the inner ends of the slots 51 and the tracks 13 willbe at their lower limit of movement. \Vhen the upper ends of the arms 50 are moved to their outer limit of movement, the pins 53 will be at the outer ends of the slot 51 owing to the fact that swinging the upper ends of the arms 56 auses the lower portion in which the slots 51 are, to he moved inwardly, and as the slots 51 are curved upwardly from their inner ends to their outer ends, the tracks 13 will he in a raised position when the pins 52 are at the outer ends of the slots 51.

livotally attached to the upper end of one of the arms 50 is a rod 53 which extends longitudinall of the frame 16 and outside of it to the pivotally mounted lug 54 to which it is pivotally mounted. This lug,5el has its pivotal point 55 at its upper end and the arm 53 is pivotally attached to it at 56. The lower end of the lug '54- extends below the portion of the frame 1.6 upon which the roller 39 rolls and is designed to be engaged by the shaft 19 as said shaft passes by it.

When the impression roll is moved to its outer limit of movement, the shaft 19 engages the upper end of the arm 50 and causes it to be swung to its outer limit of movement and causes the outer end of the tracks 11 and 12 to be swung upwardly and the tracks will he maintained in their position until the impression roll is drawn to its inner limit of movement, and the shaft 19 engages the lower end of the lug 54 which causes the upper end of the pivotally mounted arm 50 to be drawn inwardly and thgs lower the outer ends of the tracks 11 and 1.2.

Mounted above the upper inner portion of the frame 11 and at the rear of the frames 16 and 17 is a feeding table 57 inclined from its "signed to allow -the printing roller 30 to be passed under it and toallow the papers to be printed to pass over the feeding table- 51 and the guiding plate 58 into the grippers 22 which are mounted on the impression roll 20. Attached to the inner upper portion of the frames 16 and 17 and between said frames is the rod 59 having a-series of guides 60 attached thereto, and extending outwardly and downwardly therefrom so that their lower ends engage the outer edge of the plate 58. These guides 60 are weighted so as to engage the plate 58 and constantly keep the paper being fed into the impression roll 1n a un form position so that'the grippers 22 on the rinting roller will grasp the paper and t us it will be wound around said roller. As the rod 59 is rotatably mounted, it will be seen that the lower end of the guides 60 will swing upwardly and downwardly and thus allow the paper to be passed between said guides and the plate 58.

In practical use, the operator laces the paper to be printed on top of the ceding tale 57 and operates the mechanism of the device by means of the crank.47,which opera tion causes the impression roll to be moved from its inner limit of movement after the pa er has been engaged by the impression rol 20 and the grippers 22 over the forms of type which are mounted on the form bed 15 to the outer end of the frame 10. As it appreaches the outer end of said frame, the

shaft upon which the impression roll is mounted engages the upper end of the arm which causes the said upper portion to be moved outwardly, 'which causes the" outer end of the tracks Hand 12 to be swung upwardly. Then by reversing the rotary movement of the crank 47, the impression roll moves inwardl until the shaft 19, upon which the printingroller is mounted, engages the lug 54, which causes the upper end of the arm50 to be drawn inwardly, the outer ends of the tracks 11 and 12 t0 move to their normal limit of movement, and the device is then in position for printing the next sheet. The ink cylinder 31 is constantly rotated on account of its engagement with the rollers 29 and 30 and a constant feeding of ink from the cylinder to these rollers is provided for} Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, therefor is 1. In a printin press, a frame, a pivotally mountec upon which the impression 'roll of the press is designed to be mounted, an arm pivotally attached to said track, having a slot near its lower end, a pin in said frame and extending into said slot, so arranged that as the upper end of the arm is'moved limit of movement outwardly,
