PRINTING-MACHINE.

SPECIFIICATION forming part of Letters Patent No'. 398,042, dated February 19, 1889.

Application tiled January 20, 1888. Serial No. 261,349. (No model) To @ZZ whom t may concern:

Be it known that I, HENRY H. HARRSON, of the city, county, and State of New York, have invented a new and Improved Printing-Ma' chine, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front elevation of my new and improved printing-machine. Fig. 2 is a side elevation of the same. Fig. 3 is a central sectional elevation taken on the line a: of Fig. 1. Fig. 4 is a broken detailed view of the paper-roll and spring-holder for the same.l

naled the roller C, of wood, hard rubber, metal, y

or other suitable material. Above the roller O is the type-roller D, in the tace of which is secured the type D', preferably executed in soft-rubber sheets. The gudgeons CZ of the type-roller D are held in open bearings d', made in the standards A A' which open bearings communicate with diagonal slots (Z2 in said standards, so that the said roller may be readily removed from said standards and replaced for removing or changing the type D', as circumstances require. Bearing upon the gudgeons (Z are the curved springs cl3, which press the type-roller down upon the lower roller, C, and the paper E. One end of each spring d3 is secured upon a fixed step, d', bya screw, d5, and the spring is curved at d to fit upon the gudgeon, and its opposite end, d?, is curved back to a horizontal position above the gudgeon, and upon this end acts the adj usting-screw d8, held in a lug, d, and by which the pressure of the spring upon the gudgeon may be regulated to regulate the pressure of the printing-wheel upon the pa per. By removing the screws d8 the springs d3 may be swung to one side ott from the gudgeons d, and the printing-roller removed from the machine through the diagonal slots cl2, as will be clearly understood from Fig. 2.

The paper E is wound in a continuous ribbon upon a drum, F, held to revolve between two Corresponding rearwardly projecting arms, F' F', of the side standards, A A'.' From this drum the paper passes between the rollers O D, which are revolved intermittently for drawing the paper along and printing the same with an impression from the type D', one complete impression being formed for each complete revolution of the type-roller D. G G' are the cutters or shears for cutting the paper E as it issues from between the rollers O D. The cutter G' is stationary, and its sharpv edge is on a line with the point of contact of the rollers C D, and a gnide-plate, G2, is held above it for guiding the paper over the cutter G'. The cutter G is like the blade of a pair of shears, and is pivoted at a, and is formed with an extension, a', to which the springs H H' are attached, which are attached also to the post I, rising from the base B at one side of the cutter G, and which springs serve to normally hold the blade elevated, as shown in Fig. l, and permit it to be closed by the lever J for cutting the sheets of paper.

The lever J and the rollers C D act in a certain relation to each other as to time, and are all operated from the same crank-shaft, K, through the mediumot" a mutilated gear-wheel,

L, formed with a cam, L', secured upon the said crank. The mutilated gear L meshes with the pinion M on the gudgeon b of the roller O and communicates intermittent motion thereto, and the roller O is geared tothe type-roller D by gear-wheels N N', so that the roller O communicates intermittent motion to the sai d type-roller. The lever J is fnlcrnmed upon the gudgeon b, as shown in Fig. 2, and at one end reaches under the extension a' of the blade G, and at the other end reaches under the shaft K, so that t-he cam L will depress the said end of the said lever and correspondingly elevate the opposite end of said IOO (l l) are at rest, and the blade (l remains at s This to the teltlj and applied through the rollers rcstwhilc the rollers C l) are in operation, so

that b v a single revolution ol' the crank K the rollers (l l) will. bc revolved a complete revolution, inkingl thctw'peD' and printing a strip P O to the type on the roller l). Alf'pon the hollow gudgeon 7.1 secured the pointer in", which acts between the. small lugs m m at thc end of the outer tuhe/`, which lugs act as stops to the pointer und prevent the inner tube 'from beingI turned too l'ar in either di l rection, and the pointer serves also as an Aindicator to assist in registering the holes` in ol' the paper li, and the blade G closed and rel' turned, thus ellccting the cutting ott' ol the printed portion oli' the paper.

The type is inked bythe two inking-rollers O P and the tubular ink-reservoir Q.

The giuflgeons c oli' the roller O are held in open bearings c in the standards A A', and

said roller is held in contact Awith the roller I l) by a coiled spring, O', at cach end. The lower end ot" each of these springs is made fast to a lugl on the standard, while to its upper end is secured a ring, c2, which slips loosely upon the gudgcon c. These rings or sleeves may be @asiliremoved from the said gudgeons, thus ('letaching the springs from the roller @,which, owing to the open bearings c, may be readily removed and replaced, which necessary to remove and replace the typeroller lf).

The giu'lgeonsf olf the upper inking-roller are likewise held in open bearingsf", formed in the end pieces, l R, which are pivoted at /t to the standards A A', and on each of the gndgeons is placed a loose ring, f2, to which is attached the upper end o'l a coiled spring,

I, the lower end ol? which is made fast to the standards. lv slimiing the rings f2 oft' from the gudgeonsfthe wheel P may be lifted out ot' the hearingsj". lfor holding the roller P in contact: with the roller O, the end pieces, R R", iurn on pivots 7i lor that purpose, and owing to these pivots the roller lf may be pushed bach awa)` from the roller() when the same is to be removed from its bearings. The ink-reservoir (.2 is join-nailed in the said end pieces, Vit' l{,and in a trough, lt, which serves to catch an)r drip ot' ink.

The reservoir is inade oll twotubesM/'P/Q one placed within the other. The outer tube,j, is l'orincd with a seriesoi' holes, j?, and the inner with a correspoinling series' ot' holes,j3, and around the outer cylinder is placed a lelthj". The outer tubc,j, is open at one end and t'ornwd with the annular liange 'i at the opposite end. The inner tube, j", is formed with a giu'lgeim, 7.', at one end and with a hollow giulgeon, li", at the other, which passes through the openingl 1T in the end ot' theouter tubehj. lhe inner tube, 1j', is lilled with ink through this hollow gudgeon lt", and is closed b v a plug, 7:?, which t'orms one of the journals for the hiking-roller. liv turning the inner tube so that its holes'ji do not register with the holes/"f ol' the outer tube the [low ol inl; will be stopped, but by tu rn i ng the inner tube to bring` its holes into registration with the holes ol the outer tube inl: will be supplied the two tubes.

The drum l?, on which the paper E is wound, is composed of the end disks, p p, and the core F2, to one end oil which the disk p :is attached. One end of the core Fi is recessed, as shown at q, to receive the head oi the rod. F3, held in a sleeve, F4, attached to the arm F of the standard A. The rod F3 is provided with the small rod F5, which passes through the said arm F', and in the sleeve Fll is placed the coiled spring F, which constantly presses the rod F3 into the recess q, thus holding that end of the drum, the opposite end being held by a stud, s, attached to the opposite arm, F', of the standard A. The diskp is attached to the'rod F3, as shown in Fig. 4, and said disk is provided with a rod, t, by which the said disk and rod may be conven iently drawn to the position shown in dotted lines in ligx 4f, for releasing the core F2 and for receiving another core fitted with paper.

The roller C is prevented from turning back b v a spring-pawl, S, which engages with. the teeth of the gear-whecl N, as shown clearly in Fig. 7, and the type roller is prevented from turnin g too i'ar by hand or by momentum by the pawl T7 formed with the arm u and toe u', which latter engages with a toe, u, on. the hub of the pinion M. lhe arm u projects in the path oi the cam L and is struck. thereby, so that the cam at the proper time lifts the pawl T out ol engagement with the projection u? and releases the parts. To cause the pawl T to drop suddenly at'ter the cani L has passed the arm u, l form said pawl with the extension r and connect to this the lower end of the spring` i", which is connected at its upper end to the standard, so that the spring exerts a constant tension upon the pawl.

Having thus described my invention, what l claim as new, and desire to secure by Letters p Patent, is-

l. In a printing-machine, the standards A A, having the open bearin d and diagonal slots di, reaching to the same, in combination with the type-roller D, lower roller, C, gudgeons d, springs d3, pivoted to the standards and arranged. to rest upon. the gudgeons d, and thc screws di, held in studs attached to the standards and adapted io hold the springs (Z3, substantiall)T as described.
