Specification of Letters Patent NO. 24,626, dated July 5, 1859.

To all whom it may concern:

Be it known that I, GEORGE P. GORDON, of New York, in the county and State of New York, have invented certain new and useful Improvements in the Construction and Operation of Printing-Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference placed thereon.

Qf the drawings, Figure 1, is an elevation of the first or B. side of the press, as it is to be operated, taken from the outside of the machine, certain parts being indicated by dotted lines, which will be hereafter described, the red lines showing the sheets of paper, in the several positions they may assume. Fig. 2, is an elevation of the L. side of the press, from the outside. Fig. 3, is a longitudinal section through the center of the machine looking from the B. side and toward the L. showing the position of the parts when open so as to get at the form, that is to take off one or put on another, or to prepare the form for work, by overlaying underlaying, or otherwise.

Nature of inocnti0n.The nature of my invention consists principally in providing a horizontal bed, for the form of types, which has an alternating reciprocating motion, and carries with it the ink-distributing cylinder, which having been properly supplied with ink, and the same distributed, conveys the distributed ink to the rollers which supply the ink to the form. Also, in a new arrangement of crank, cam and connecting-rod, with such reciprocating bed as to give it its alternating reciprocating motion through a common set of gearing. Therewith subjoining a stationary feedboard, having gages which alternately rise and fall, as the grippers advance to receive the sheet and take it to the impression, and again rise, so that the next sheet may rest against the gages, to be taken by the grippers. And further, in arranging two sets of grippers with a fly or deposit board, so that one set shall receive the sheet and draw it from the feed-board and carry it directly to the form of type, and the impression, under the platen, where the secondset of grippers take the sheet, peel it off the type, and carry it to the fly-board where the second grippers drop and deposit the sheets one after another in rapid succession.

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

As presented in Fig. 1, of the drawings, a main shaft (a), which gives motion to all parts of the machine, is upon the B side of the press, shown in its position, and upon the L. side of the press is placed the flywheel, and on the B. side 1s the driving pinion (6). This pinion gives motion to themain spur-wheel (b) placed upon the cranked shaft (0) upon which is placed on the opposite side of the press, the wheel which forms a connection with the platen (D) through the connecting-rod (d). On the B. side of the press is another and similar connecting-rod placed eccentric from the center upon the outside of the spur-wheel (b), which will be known as ((l'). The dotted lines in Fig. 1, show the form of a cam (f), which is intended to operate the two part lever-cam (g, g), which is in one piece. This last cam, through the levercam (p), operates the feed-gages attached to the underside of the feed-board, causing these gages (i, z) to rise and fall at the proper times, so that the sheet may be fed to or against the gages. The twosets of grippers will be known as A and B. The set A will be the feeding grippers, whose ofiice it is to take the sheet from the feedboard, as the grippers drop from their elevated position, and carry it directly to, and upon the form of types. The slot or open cam designated by letter O in the drawings performs the duty of guiding the grippers A to their proper places, their fulcrum being the movable arm attached to some point of the reciprocating bed.

The grippers A, consist of two parts, upper and lower, each being held firm in its position by springs on either side of the press, so that the lower and upper parts will be compelled to connect and separate at the proper times, so that there may be no suspension, for want of taking the sheet when it has been placed to or against the gages (2', i). To the lower part of the grippers A, is by means of a cross-bar (70) attached a sort of cam or lever (Z), which is influenced by and actuated, when in motion by the one pieced lever cam (g, g) which causes these feeding grippers to open and receive the sheet as it is fed to the gage and carry it directly to the type, so that when the reciprocating-bed arrives under the vibrating platen gives the impression to the form as it lies in position parallel with that of the bed, even though the bed, may be placed horizontal, vertical or on some angle at variance with these positions. The two part lever (g, g), consists in two arms each at angular positions in relation to the other, nearly forty-five degrees, but may be varied to suit contingent circumstances; but of these two parts I desire to more particularly explain: viz, the one arm (9) extends from its axis downward where its lower end rests upon the cam from which it receives its motion from the dotted line cam Fig. l; the motion of the said arm (0), together with the motions of the reciprocating bed controlling the grippers A, in all their movements. On the opposite side of the press a lineal cam (p) performs a corresponding office, the shape being somewhat similar, compels one side to act in contact with the other, so that by the cams on both sides of the press cause the grippers A to actin harmony. The second set of grippers B, or flying-grippers, I will set forth as follows: viz, at the back end of the bed are hinged the axes of the two cams, one on either side the press, and these are to act in harmony in all the movements. (These cams carry the grippers B, which will be presently described. Within these cams (see 9 in drawings) is lineal slot governing and controlling the various movements of the grippers, B, or secondary actors in the process, as they take hold of the sheet from the type, by means of the several motions of the press, then convey the sheet over the fly-board (r) where it drops and leaves it properly piled upon the pile-board in an even heap, the form and position of the board being such that the sheet will necessarily adjust itself to its position so as to make an even pile, one

. sheet succeeding the other as they are successively supplied at the feed board. These lineal slots are in their movements controlled by fixed studs in the sides of the platen, which platen (D) vibrates upon its own 7 axis, so that, by the united action of a horizontal bed, having an intermittent reciprocating motion and a platen having a reciprocating vibrating motion will bring the grippers B at the proper times to their proper places, so that these grippers will take the sheet at the time and perform the operations before described. The fiy-board when the press is in operation is stationary, (see 1" in drawings), but to facilitate making forms ready and like work may be turned over so as to be out of the way. Besides the foregoing the grippers B, are in the operation of opening and closing further controlled by the spring (25 and trip-lever, or cam w), the first serving to close and keep closed the grippers, during all the time the sheet is to be held until it is dropped upon the fly-board. By reference to Fig. 1 in the drawings, a lever-cam will be found 22) which being acted upon by the trip (14) opens the grippers B, so that the sheet may be dropped as before described. The grippers B must come close up to the platen when at full impression, in order that it may be sure to seize the sheet on its margin at the proper time to secure its taking the sheet. The better to insure this the chase is made so as to form a part of the press, its front side having raised parts, at intervals, and the grippers to fall in the open spaces or in tervals leaving the elevations ('w) in red, Fig. 3, so that the lower jaw of the grippers B, will be sufficiently low as to pass beneath the sheet and this as the upper and lower jaws close upon the sheet secure and carry it to the proper place for deposit and piling, as before described.

Attached to, and forming a part of the under side. of the bed, is a fixed cam (:0 see Fig. 3), which being an open cam will be best explained by reference to the drawings. A vibrating arm (y) works upon its axis (a) through the connecting-rod 00), by whose, combined movements with the cranked shaft (0) all the necessary opera tions as heretofore set forth, are performed and controlled. In order the better to control the regular lateral movement of the reciprocating-bed as well as to give a revolving motion to the ink-distributing cylinder which travels with the bed, and substantially forms a part of the same, is a rack, (see as Fig. 3,), to compel the bed to keep parallel with the frame, at the same time it governs the main inkdistributer (66).

(0, c) are the ink-rollers, which having received the ink from (a), convey and impart it to the form of types to be printed from (7)).

Having thus described the construction and operation of my machine, what I claim as new and desire to secureby Letters Patent, is

1,. Taking the sheet from the feed-board, by grippers or their equivalents, and presenting it directly to or upon the form of types, thence conveying it to the place of impression, so that it may be printed.

2. The combination of a reciprocating bed with a set of sheet receiving grippers, so that the movements of the bed may control the action of the grippers, in order that the sheet may be taken from the place of feeding to the' place of printing, by such grippers.

3. The combination of a vibrating platen, having a stationary or fixed axis upon which to vibrate, with a reciprocating bed.

4. The combination of a set of sheet piling grippers; Which will peel or take the printed sheet from the face of the type and pile it on its place of deposit, with a reciprocating bed, operating substantially as described.

5. By use of automatic grippers, piling the sheets tlirecttv before, or in front of, and under the eye of the operator, so that he may at once detect any liTlPOl'fQCtlOll in the impression.

(3. The combination, in one and the same machine, of a set of grippers to take the sheet and carry it to the place of printin with another set of grippers to take the sheet from the form and pile it substantially as described.

7. The arrangement and construction of a chase, as described, in combination with the piling grippers, operating substantially as set forth.

8. The giving a reciprocating vibratory motion to a bed, or carriage, allowing the necessary intervals of time for the purpose of receiving the sheet, or the impression, either or both of them, by means of the cam t'orniing a part of the bed, the cranked shaft, the vibratingarm and the connecting-rod, or their equivalents, all of which is herein fully described and set forth.
