Referring nowspeoically to the drawings, and in which like reference characters refer to `like parts throughout, side members lil and Il are provided which form the main portion of the Each ofthese side members has a base portion I2 which rests upon a table or any other level place to support the press,v and upwardly extending, integrally formed extensions I3, `I3 upon which some Lof` the .operating parts of ithe press are mounted. A front plate it is `provided which has ears I5, `It thereon on each side through which hollow rivets I6, It are inserted which pass through the side members -Ill and I I, respectively, with struckout upstanding portions il, I'Iat each sidethereof on the upper vface which formguidesrfor the paper as it passes.

into the printing press, as hereinafter described. A rear plate I8 is providedwhioh has ears I9,

each of the side frames IO and I I, providing the frame at the rear portion thereof with supporting means for the' paper, and also serving with the side members Il] and I fI and the front plate I4 to form a complete supporting frame for the press. It will be noted that theffiont plate Iii and the rear plate I8 are curved `downward to `conform `to the contour of the endsof each of theside vi9 ateach side thereof andthrough which hol- AloW rivets 20, `2() pass, which also pass through 'the printing operation,

members l@ and il and thus provide a neat appearing and suitable bed upon which the paper is received for printing and upon .which the paper is received after it passes through the printing press. The rear plate i8 has struckup portions 2i, i which serve as side guides for the paper after it passes through the press and while the printing operation is being performed thereon, in order to hold it in proper alignment with the printing press.`

A printing cylinder 22 is provided, mounted upon an axle 23 which extends through and is mounted in the side frame members lil and Il and which is bent at one end into a crank portion 2li to be grasped by the Operator in order to rotate the cylinder. The cylinder is mounted in fixed relation upon the axle 23 so that as the axle 23 is rotated the cylinder also is turned. Mounted on the cylinder 22 at each end thereof` are tires 25, 25 preferably made or" rubber or of other similar substance, which are held onto the cylinder by their elasticity and because of their shape and form perform five functions: First, means for holding the type bars in position .upon the cylinder second, frictional means for causing the rotation of the ink roller and impression roller; third, the spreading and holding of the paper as it passes between the cylinderand the pressure roller so that it is held in smooth position while being printed; fourth, the tires are so constructed that movement `of the cylinder is conveyed to the ink roller and impression roller and they are rotated only during the printing operation; and fifth, the tires have tread portions thereon the ends of which form stops for the paper placed in the press so that printing is properly placed on the paper.

The tires 25, 25 have treads 2S, 26 thereon which extend substantially three-quarters of the way around the tires and terminate abruptly forming shoulder portions at each end of the tread i portions, one set of which forms a stop for the Ipaper inserted in the press at the beginning of Ythe printing operation. The outer peripheries of these treads 26 have ribs 2l, 2l thereon extending circumferentially thereof, these ribs being formed with vertical faces on their outer sides and inclined faceson their inner sides extending outward to their edges which engage the paper as it passes beneath the printing cylinder when this cylinder is rotated and exert a lateral pull on the paper so as to hold it fiat and taut during thereby preventing wrinkling of the paper and holding it in smooth position while the printing operation is being performed. As the edges of the ribs are compressed, there is a slight movement outward until the vertical faces of the ribs appear undercut.

This movement lis dueto the long angle of the faces of the ribs on the inner sides and the vertical faces on the outer sides. The tread portions 25 also perform the function of contacting the inking roller and the pressure roller through rthe paper, hereinafter described, in driving them during the printing operation.

The tires 25, 25 also have V- shaped grooves 28, 28 in their sides oppositely disposed and inwardly opening and extending partially therearound, within which the ends of U-shaped type slots 29,23' are adapted to be received and held during the printing operation. These type slots 29, 29 have type such as 30, 33, with quads 3l, 3| being provided to hold the type mounted therein, the type and quads being made preferably of rubber or the like, and of the character and kind described and claimed in Patent No. 2,041,499 of May 19, 1936. The ends of the U-shaped type slots 29, 29 are V-shaped to correspond to the contour of the grooves 28, 28 in the sides of the tires, with the type slots being of sufficient length to fit snugly in the tires and about the periphery of the cylinder 22. These type slots 29, 29 are placed in position on the cylinder by simply exing the tires toward the outer ends of the cylinder and inserting the slots in the grooves 28, 28 in the sides of the tires, so that they are held in printing position upon the cylinder 22 and may be easily and quickly removed in the same Amanner.

An inking roller 32 is provided having the usual fabric or ink retaining member 33 thereon of substantially the same width as the length of the cylinder between the tires. The inking roller 32 is mounted on a bell crank axle 34 in the side members ill and l I, respectively, and terminating in a crank portion 35 having an inturned portion 355 vadapted to be received and held between struckup portions 3l, 3l in the frame member it. The inking roller 32 has a pair of drums 38, 38 on the crank portion of the axle 34 so that as the axle 34 is rotated the roller 32 is moved toward or away from the cylinder 22 and held in frictional engagement with the tread portions 26 of the tires so that as the cylinder 22 is rotated the ink roller 32 is rotated at the same peripheral travel, thereby inking the faces of the type which are oi' a proper height to press firmly against the inking member 33 and receive a supply of ink therefrom and without smearing the face of the type.

The proper positioning of the inturned portion 36 between the struckup portion 3l of the frame holds the ink roller 32 in proper adjusted position both with respect to engagement with the tread portions 26 of the tires and also to engage the type 3U. The free end of the bell crank axle 3d has a rubber sleeve 39 tted thereover to hold it in position, the sleeve member being fitted tightly over the end and frictionally engaging the end of the axle member 34 to hold it in po- -sitio-n in the frame to prevent slipping of this broller 32 so that a plurality of layers of material are provided to form the ink carrying and retaining member 33. This member is easily removed irorn the roller 32 if desired for purposes of cleaning or supplying a different color ink, or the entire roller can be removed by taking the rubber sleeve 39 off the `end of the axle 34 and drawing this member free of the frame and the entire roller 32 removed from the axle and a new cr diiferent roller placed on the axle 34.

A pressure roller 4l is mounted upon a crank axle 42 which has a right angle crank portion 4'3 at one end thereof and terminates in a handle portion 44 which normally in printing position of the pressure roller extends upwardly in a vertical direction alongside of the side member Il and rests against the sleeve 39 on the free end of the axle 34, being held in this position by a spring 5, one end of which is secured to the crank porytion 43 of the axle 42 and the other end anchored `lines 5i, til of to a pin 46 mounted'in the side frame member il The spring l5 yis under tension in two positions, one ras described when the pressure roller is inoperative position with respect to the cylinder las shown inFigure 2, and in inoperative po.-

ysiti-on with the pressure roller 4'I lowered as shown in Figure 5, and out of engagement with the cylinder 32. VWhen they lever 44 is turned to inoperative position the crank `portion is beyond the center or the axle 132, the handle rests upon a stud iSd in the side member Il and the lever is held in this `position by aspring 45. The eccentric portion oi thev axle 42. provides means Awhereby the pressure roller H may rotate freely` `and at the Sametime provides means for the automatio ci'neration of the press with respect to thickness of paper, fromy thin sheets to cardboard, with the printing pressure kept constant `throughout thisrange of thickness. in Figure 3, the tires are spaced upward from the table a suicient distance to allow for the insertion `or" any paper, however thick, anda constant uniform pressure is maintained by the spring t5 .on the paper during the printing operation, regardless of its thickness. As the press is rotated forthe purpose of inki-ng the type, the

ressure roller is lowered so itis clear of the type so asto prevent inking the roller when paper is vnot fed throughthe press.

`In operation of the devicetype and type slots 2t .of the iorrn shown in Patent No.` 2,041,499 are used, with the exception that the type slots are pointed at each of their ends' to vfit into position in thegrooves iii of the tires as heretofore de-` scribed, around the periphery of the printing cylinder 22. .ln addition to the kind of type shown and described in the above named patent,

as shown..

vcharacters or the like, as may be desired. Also a pliuality of quads, such as 3i, maybe provided having face cemented or otherwise secured thereto,` on whichrnay be a pictorial illustration, a comic character, or `any other attention directingor arresting illustration, which may be fitted into the combination to make the printing more attractive or desirable. i The cylinder 22 is calibrated yvii-th lines 5i), 59 extending the length of the cylinder andother lessor length placed `midway between the lines 5t, the spacing of the lines 5t, til being such that when translated to the printed sheet they represent one-half inchland the shorter line..` Ptit, 5i represent cnemquarter inch. This providesan accurate means of scaling the layout for the printed material. The type bars may ,be place in slightly angular positiony on the face of the cylinder toiorm lines of printng diagonally on ythe printed page for attention directing or grotesque presentation if desired. u

The inking roller 32 has had the ink carryingv As shown vthe type, as

Both the type and theouads are preferably of A5 ,rubber or some other resilient material' similar it to function properly, the lever 44 is moved into the position shown' in Figure 2 of the drawings,

Vthus bringing the pressure roller it up in printing Vposititui asshownl in Figure 3, The cylinder 22 `is rotated to a point just short of where the tread 5 portions of the tires are about to engage the inking roller, in which position the opposite ends 52, ill? ci the tread portions of thetires are slightly behind and abut against the pressure roller M to ies f pre srre roller secures accurae registry of the J5 the press, and aiso enables accurate stry oi the paper Yif it is desired to print in two or more colors by running the paper through the 1re-ss after the inning roller has 5 been d and a different type set-up made.

At the same time the forward line of type comes paper, the pressure roller ii `forming also an impression base for the type as it passes over the paper, so that as the, cylinder is rotated the paper `in eiiect is pulled between the roller Kil,

which thus acts both as` a" feed and a pressure 153.5 roller. The printed paper is carried'throughover the rear plate i8 between the guides 2i, 2i pro-` vided thereoinjand ejected at the back side of For other impressions the cycle of o; antityof ink beine' added tothe inl-ring roll as sempre'` proper thereto, and various l'rinds and sizes of type'can provided, with various miscellaneous characters, quads and the'lilre, sothat endless amounts produced on the small press at minimum of `cost exceedingly cheap in operatien,` ,both in cost of the and the materials `its operation. l.
