MACHINE FOR WTTING PAPER.V

Specification forming part of Letters Patent No. 28,895. dated June 2G, 1860.

To a/ZZ whom it may concern.-

Beit known that I, ANDREW OvEREND, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Machine for Vettiug Paper Preparatory to the Printing thereof; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side elevation of my invention; Fig. 2,a side sectional view of the same; Fig. 3, a sectional plan or top view of the same; Fig. ga horizontal section of the same, taken in the line Fig. l.

Similar letters of referenceindicate corresponding parts in the several figures.

The object of this invention is to obtain a machine by which paper may be moistened in a very expeditious and thorough manner preparatory to the printing thereof.

The invention consists, substantially, in the employment or use of a reciprocating frame, perforated water-supply tubes, feed and receiving boards or platforms, and a holding device arranged for joint operation, as hereinafter described, to effect t-he desired end.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A representsa framing, which may be constructed in any proper way to support the working parts, and B B are two parallel ways secured horizontally in the framing A at its upper part. On these ways a frame or carriage Gis placed, said carriage being provided at each side with rollers l) l), which run on the ways B B. The carriage C is formed of a rectangular frame having wires fitted longitudinally in it at a suitable distance apart, as

shown clearly in Fig. 3.

In the lower part of the framing there is placed horizontally a driving-shaft D,on one end of which a wheel E is secured. This wheel E has a heartshaped recess or groove c at its inner' side, in which recess. or groove a pin d at `the upper end of an arm F is fitted. The lower end of the'arm F is attached to a shaft Gin the lower part of the framing, said shaft being provided with an arm H, which extends upward and passes through an eye e at the outer part of the carriage C.

I I J J are four tubes, which are placed in the framing A, two above and two below the waysB B of the carriage C, as shown in Figs. l and 2. These tubes I I J J communicate with a water-reservoir or with pumps, and the under sides of the upper tubes I I are perforated, and also the upper sides of the lower tubes J J, as shown at e in Fig. 2.

At one end of the driving-shaft D adjoining the wheel E there' is placed an eccentric K, which bears against the lower end of an" arm or lever L, attached to one side of the framing. The lever L has connected to it a pawl M, which engages with a ratchet N at one end of a shaft O, which is directly above the shaft D and in the same axial plane.

At about the center of the shaft O there is a pinion P, which gears into a vertical rack Q, attached to one end of a platform R. This platform R is iitted between guides ff in the framing, as shown in Fig. Ll. To each side of the platform R a vertical rod or bar S is attached, the upper ends of which form bearings for a shaft T, on which a roller U is placed. The bars S pass through suitable guides g, attached to theframing. (See Fig. l.)

On the upper part of the framing' A there is placed a platform V, which is directly over the platform R and nearly or quite equal in length to it. (See Figs. l and 2.)

To the inner side of the wheel E there is secured a curved arm X, the form of which is shown clearly in Figs. l. and 2, mostly by dotted lines. Against the outer side 'of this curved arm X the upper end of an arm Y bears, said arm being attached to one end of a shaft Z, which is in the lower part of the framing A and has a spiral spring A on it, said spring keeping the arm Y in contact with the curved arm X or with-a stop attached to the framing A.

To the shaft Z two curved arms B B are attached. These arms'B B extend upward above the platform R nearly to the ways B B, and their upper ends are connected by a plate C. To the ends of the ways B B and over t-he plate C there is placed a rod D', the ends h of which are bent at right angles with its main portion and are fitted in loops or eyes z', attached to the ways B B. One of the ends 7L of the rods D' is bent inward a short distancetoward the center of the framing, as

shown by the dotted lines in Fig. 3, and to the front end of the carriage C at one side there is a swinging pendantj.

Through the platform R four rods 7c pass, each rod having a spiral springl placed on it. The rods 7c are fitted loosely on the platform and the lower ends of the springs Z rest on the platform. To the upper ends of the rods k a plate E is attached. This plate E is parallel With the platform R and rests on the springs Z, the rods 7a serving' as guides.

The operation is as follows: The paper to be moistened (shown in blue) is placed on the platform V and is folded in quires or in bundles of any suitable number of sheets. The roller U rests on the top of the pile of sheets on the platform V and the wheel E is rotated by any convenient power. As the wheel E rotates, a reciprocating movement is given the carriage C by means of the groove c, arm F, shaft G, and arm II, and each time the carriage C reaches the termination of its stroke when moving in the direction of arrow l the attendant places a bundle of paperon the carriage C,

and the carriage in moving in the direction indicated by arrow 2 passes between the perforated tubes I I J J, and the paper on the carriage has water ejected against its upper and lower surfaces, the water being ejected through the perforations e of the tubes. As the carriage C approaches the termination of its stroke in the direction indicated by arrow 2, the pendantj strikes one of the arms 7L of the rod D and elevates said rod, so that the edge of the quire or bundle of paper on the carriage C will pass under said rod. As the carriage C recedes or moves in the direction of arrow l, the rod D drops on the paper, holdin it on plate C', and the carriage C moves from underneath the paper, which, When the carriage is fully from underneath it, is allowed to drop on the plate E by the removal of the plate C outward from underneath the rod D', thc plate C being actuated or thrown outward from the rod D at the proper time through the medium of the arms I3 Y X, the spring A at the' proper time throwing back the plate C toward the rod D', so that the rod D may hold the succeeding bundle or quire of paper at the return of the carriage C. Each time the carriage C reaches the termination of its movement in the direction of arrow l the eccentric K actuates the arm L, and the latter moves the pawl M, which actuates the ratchet N sufficiently for the pinion P to slightlyv elevate the rack Q, and consequentlythe platforms R V. rIhis elevation of the platforms occurs just at the time the operator removes a. quire or bundle of paper from the platform V, and the movement is essential in order that the paper on V be relieved for an instant of the pressure of the roller U to enable the operator to remove the top quire or bundle from V. As the paper is fed off from the platform V, is moistened, and dropped on the plate E', the latter, with platform R, descends as the roller U rests or bears on the top quire orbundle on V. Consequently the paper on E will not be allowed to come in contact with the lower tubes J J.

The machine, it will be seen, works automatically, one operation being required only to feed the paper to the carriage C and remove from time to time the moistened paper from the plate E. The water maybe ejected through the tubes I J either by hydrostatic pressure or by pumps.

IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The reciprocating carriage C, combined with the perforated water-tubes I I J J, the feed and receiving platforms V R t', and the paper holding and discharging device formed of the rod D and plate C', or their equivalents, arranged for joint operation, substantially as described.

AND. OVEREND.
