PEINTIN(ir-PRESS. Y

Specification of Letters Patent No. 10,588, dated February' 28,1854. I

VTo all whom t may concern.:

Be it lmown that I, STEPHEN of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Printing- Presses, which I denominate a Combinaf tion-Press; and I do hereby declare the following to be a full, clear, and eXact description of the same, reference being had to .the accompanying drawings, making a part hereof, in which- Figure 1, represents a top View or plan of the press. Fig. 2 represents Aa View from one ofthe sides. Fig. 3, represents a view.

of the side opposite to Fig. 2, and Fig. V4f', represents a vertical longitudinal section through the'press; Fig. 5, a View of a detached portion.

Similar letters in the Several figures denote like parts.

The natureof my invention consists, more particularly, in the general arrangement of the various parts of a printing press,lso as to combine great utility, with the simplest and cheapest manner of construction. t

To enable others skilled in the art to make and use my invention, \I will proceed "to describe the same with reference to the drawin s.

glhe frame A may be suitably and sub- Stantiallybuilt of cast iron, and in proper ybearings therein is placed the shaft B, carrying the balance wheel C, through which motion may be given .to the several parts of the press by hand or any other power. At or about the center of the press onthe shaft B, is secured a spur wheel D, whichr meshes vinto and rotates a large gear 'Wheellv E, on; a`

shaft F., also supported in the frame A. Qn said shaft F, is also placed ythe eccentric pins `(one only being seen in the section Fig. 4;)

forforcing up the platen, or for throwing off the impression, and which will be, hereafter, more fully described. The shaft F, carries on its extreme ends, outside of the frame of the press, the two cam wheels G, (Fig. 2), and H, 3), in the face of which cam wheels are cut the ca m grooves (respectively) a, b, yinto which kpins c, c5 on the arms I, J, work andgive'tov the rock Shaft K, the motions necessary kto .operate P.

the springholders lo, as seen in the "and around the pulley T, which are forced up against the sheet by the rod Z.V

The spring holders/h, are hung on a rod f,

and in `said rod longitudinally is cut a slot (represented by a red line in Fig. 1,) into which av small projection on the boss or sleeve of the spring ts, and admits of said springs being run out or in on said rod f, so as'tobe adjusted to the size or shape of the paper to be printed upon. `Around 'the rod f, is coiled a small spring m, which winds up as the platen plate N, goes downthe spring holders la, being forced up against thepaper by the fixed rod .or bar n, against which they rest. `When the platen comes up, the uncoiling of thef spring Wo, throws out drawing, and releases the sheet. i The ink trough P, is hung upon the frame `by springs o, 0, which allows it, and ink f 'roller Q, hung in it, to adjust and adapt themselves to the intermediate ink roller R which, isplaced betweenthe ink rollers O,

Q, for conveying theuink from one to the otherI of, said rollers. On the end of the roller Q, is a ratch p, into which a weighted `pawl may work so as to'rotate the roller in theinktr'ough, and said roller may also be grooved with shallow small grooves, for

.betterV carrying up and distributingthe ink.

The roller O, may have a double thread or screw cut upon one of AVits ends .for giving it a' transverse motion, in addition to its rotaryinotion, which last it receives from the pulley S, ,on the shaft B yby means `of a twisted or crossed belt g, passingaround it, is attached to the axis of said roller O. Y

Thefpaper table AU,is so placed,.that the sheets,` or other thing to be printed upon may be conveniently placed `on the platen plate'N, where it is caught bythe spring holders, as before described and carried down -to where it is to receive the impression-the form having been previously inked by the rollers `e, e. `The eccentric pin r on the shaft F, thencatches into'the toggle arm V, and' forces up the platen against the form. Thebed W is permanentlyXedv to the frame by the screws s, s, and should be Asufhciently rigid to receive the pressure of .the platen. The guide piece L, hasarms t t,4at each end of it which unite inaspring plate (shown by dotted lines in` F ig: 4) said Vplate having slots in it through which set `pushing down said handle, the impression.

screws pass, by which the inking rollers may 'be allowed to yield or adjust themselves to thejplaten plate.

The' platen X, is hung` upon the curved arms Y, (one only being seen in Fig. 4)-

the other ends of v.said arms Y, being atV i tached to a rock shaft Z, which issupported inthe frame of the press. In the `same rock shaft Z, is also, placed, the Vspring arms u (one 'only being seen) which support the inling roller R, and which roller, whe'nlthe platen is forced up againstthe b ed or form, is thrown, by the partial rotatron' of said shaft Z, against the roller l '1n the lnk trough for the purpose of receivlngfanother supply of ink. j

The impression is regulated by means lof four screws o, c, (two only being seenin Fig. 4, in red lines) one at each corner of the platen, by which means a form may be workedin any part of the platen. The bed being stationary, and the platen vibrating, but confined at the two corners, cannot yield out of itsplane, these set screwstherefore make upa perfectadjustment of theimpresi sion. j

The toggle arm V, has a cord fw, attached to it which passes up and around a pulley m, to which there is a handle 4conveniently placed near where the paper is placedon the platen plate, so` that the operator, by may throwf'oif Fig. 5, represents a perspective view `of the spring arm or plate which` carries theguard i i vor guide plate h, detached from the press,

`and shown in placeinjdotted lines in Fig. 4,

inl which `l represents thejslots, and 2-the set screws therein to allow it to move-from the platen or platen plate,and 3 a coiled spring `behind it, (represented in dotted lines), one end of which spring'is fastened to said plate-the other endto the frame of the press, the object of the "spring being to allow the rollers` to adjust themselves'to the the extent of their movement. When `the rollers have passed down, and the impression is taking the guides z, (there being one at each side of the press,) as well asthc form or the spaces between the forms, so as to allow the sheet to come fairlyupllto the form.

for carryin the inking rollers to `andfroin the form,.t e Vspring plates with theguides i h, `at each endA of the rollers, for causing said rollers to pass over the form in a plane parallel to the form, their general motion being in the are of a circle, substantially as described.

2. I also claim hanging the platen X, and the intermediate ink roller R, to the same rock shaft Z, by their respective arms Y,

and u, so that the vibration of the platen, shall throw the intermediate roller, first, to the grooved ink roller Q, and then to the ink bearer O, for the purpose of receiving 410 Q and distributing the ink from the ink trough at every vibration of the platen subf Witnesses:
