IMPROVEMENT lN PRINTING-PRESS ES.

Specification forming part of Letters Patent No. 48,493, dated June. 27,1865.

To all whom it may concern.

Beit known that I, JAMES SANGSTER, ol'Butfalo, in Erie county, and State of New York, have invented certain new and useful Improvements in Printing Presses; and 1 do hereby declare that the following is a full and exact description thereof, reference being had to the. accompanying drawings and the lettersof reference marked thereon.

The nature of my invention relates to improvements in card or ticket printing presses and it consistsin, first,a movable orrevolving bed with flat plain surface, upon which the tickets are printed and numbered; second, a revolving bed with azsmooth circular surface surrounding it, upon which the tickets may be numbered; third, insuspending the inkingroller-between two spring, one above and the other below.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I coustructmy press ofthe usual 1'natcrin1swrought and cast iron.

In the drawings, Figure 1 represents a side elevation of the press, showing the revolving bed with the device for giving motion to the same, also the crank which raises and lowers the type-bed, and the arrangement for giving the necessary motion to the inking-roller, the

device for holding-the cardboard or paper in place whileprinting, and. the screwfor adjusting the revolving bed. Fig. 2 is a back view of the press, showing the parts similar to Fig. 1, with the mechanism 'for giving the lateral or swinging motion to the distributingroller, also for giving the revolving motion to the inking-rollers and the driving-shaft; also the shaft on which the inking roller swings while inking the type.

The same letters in the several figures represent similar parts in each.

A A is the frame, and I P l are rods which bolt it together.

B is the revolving bed. G is the arm or lever that moves it.

E is a pawl, which swings ona center at the point E on the lower end of thelever. G. Its

lower point is pressed by the weightl into the teethot'the ring 0, which ring or wheel is fastened to the side of the revolving bed by means of bolts or screws.

J is a connecting-rod,fastened at the joint I of the lever G and at the joint N of the type-beam Z.

M is the main or driving shaft; N, a crank upon the same.

L is a connecting-rod, fastened at the joint N and connected with the beam, which holds the type and type-bed Z at thepoint N W is a connecting-rod, which gives motion to the inking-roller. I It is fastenedto the side of machine by ajoint at N, and at the opposite end to the crank X by the joint 1?. The

crank X is fastened to the shaft Y. The shaft Y works in boxes Y and Y. It holds the frame V V, which carries the inking roller while inking the type and while receivingthe ink from the roller R.

B and B are tapc-rollers. They are surrounded by belts or tapes, such as are shown by the dotted lines and marked B The lower sides of these belts press on the surface of the revolving bed for the purpose of confining the paper or cardboard to the surface of the revolving bed while being numbered or printed from a continuous sheet or roll.

A is. a box into which the shaft'lllworks. This box is made adjustable by the screw A, which, of course, raises or lowers the revolvin g'bed.

, O O and O 0 represent the plainor-flat surfaces on the revolving bed. I have shown but two rows of those plain surfaces. There may be one row, or as many more as there are difi'erent-sized cards to be printed.

.M in Fig. 2 shows thedriving-wheelt I is aleverwhich gives the lateral or swinging motion to the inkdistributing roller. It is con'- nected to the shaft of the inking-ro1ler at J in the manner more clearly shown in Fig. 4. At J and J i't swings or vibrates on ajoint atP, and is moved by the cam on the driving-shaft marked 1 y E and E are frietion'sprin gs, which may be made eitherot rubber or metal, for preventing a backward movement of the revolving bed. When the pawl E is drawn over the teeth in the ring 0 a friction-belt drawn around the revolving bed and fastened to the lower rods, 1?

The dotted lines X represent a ratchet-whceL.

It is placed alongside of the nrnnberingwhecls and revolves with them. I

X represents an arm which is fast to the shaft Y and moves with it. It is fastened with a set-serew,X ,an d is made adjustable, so that it can lie made fast at the proper point for working the numbering-wheels, or thrown back and made fast when it is desired to work the machine without using the numbering-'wheels. This arm'or lever X", as it works on the shaft Y, is shown in Fig. 6. It acts as a pawl at the point X and moves'the wheel X by the vibrating movement of the shaft Y. The wheel is kept from turning backward by the pawl X. The machineis operated'as follows: Of course it is intended to run it by steam. By turning the wheel M until the crank-pin N is carried downward the inking-rollers R, S, and Q are made to revolve, and the inking-roller S is carried in the line of a circle, as shown in Fig. 1, in the direction of the'arrow F and in doing so passes over. and inks the type, the springs U keeping-it up against the type while passing over. By continuingthe motion the inking-roller is carried still farther toward the arrow F and the type are brought down upon the paper F and F and give an impression. In the meantime the arm G, atihe point I, is brought, downward and the endv raised up, bringing with it the pawl E, the end of which passes over theteeth in the ring 0, the weight F keeping it down against the taco or teeth of the ring 0, This measures the distance of the feed, which feed is adjusted by moving and fastening thelower end of'the arm J into either oft'he apertures marked K K K. If desired, by still turning the'driving-wheel in the same directiofi the type are raised from the bed, the pawl E is forced forward,carrying. the revolvmoved one number ahead.

ing bed the length of one ticket-or the width of one ahead, and the paper isdrawn from the point F to F and the numbering-wheel is In case the tickets are cut first before going. into the machine, which I prefer, the paper or card-board is laid, between the slats or raised ledges F and F upon the fiat surface on the bed, as at F. These ledges or raised slat-s areplaced all around the revolving bed. I have shown but three, which is enough to explain the proper construction of a large working machine.

I do not claim as my invention a revolving cylinder or roller having plain surfaces or forms upon its circumference, into which the type areset and fastened for printing. Neither do I claim a moving surface upon which the paperis placed and then carried to the proper place to receive an impression, as thatis done by means of a belt or endless apron running upon two rollers, as in the'rulii'ig-machine, or by means of a platform running upon jrollers, as in the steel or copper plate printing-machines; but

What I do claim as my inventiomaml desire.

to secure by Letters Patent, is-

1. A revolving cylinder having anumber of plain surfaces upon its periphery or circumference for the purpose of receiving the paperor card-board to-be printed, and resisting the.

pressure ot'the type when brought down against it, when said cylinder'is so constructed as to move and present its plain surfaces, one at a time, at the proper an gle to-receivean impression.

2. The springs U and U2, between which the inking-roller S is suspended, for the purposes specified.

3. In combination with the revolving cylinder or roller B, three or more slats, suchas are shown at F, F, and Fflfor the purpose of holding the card-board or paper in place while being carried under the belts B and'B, and in the positionfto be printed when found necessary to feed or lay the cards or tickets in hand. p

4. In combination with numbering-wheels,a revolving roller or cylinder, upon -theperip'hery or circumference of which the tickets or cards are numbered.
