SPECIFICATION forming part of Letters Patent No. 498,530, dated May 30, 1893.

Application filed July 27, 1891- Serial No. 400,832- (No model.)

To all whom it may concern.-

Beit known that we, SIDNEY \V. BRAINERD, residing at Cedar Rapids, in the county of Linn, and LEE 0. MANN and THOMAS E. MANN, residing at Gladbrook, in the county of Tama, State of Iowa, citizens of the United States, have invented certain new and useful Improvements in Bed and Cylinder Printing Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it eppertains to make and use the same.

This invention relates to hand printing presses, and embodies various improvements in the construction of the style of press described in Letters Patent. No. 355,407, issued to Thomas E. Mann on the 4th day of January, 1887.

The object of this invention, is, in general, to improve the construction of a printingpress having the essential characteristics of the press described in said Letters Patent, and with aview to the better adaptation of the press to the requirements of printing offices in many particulars, which will be hereinafter specifically referred to.

In the accompanying drawings, forming a part of this specification, Figure 1, Sheet 1, represents a partial side elevation of the simplest form ofpress embodying our invention; Fig. 2, a plan view of the same; Fig. 3, a partial end view of the bed-block at the end and its connected rail; Fig. 4, a fragmentary sectional elevation of the parts shown in Fig. 3, showing the construction of a device for adjusting the height of the rail at the outer end; Fig. 5, a central longitudinal section of 'the meeting ends of the middle and terminal rails and the connected iron parts; Fig. 6, a plan view of the same; Fig. 7, a central, longitudinal section of a portion of the trackdesigned to relieve the edge of the type-form from the pressure of the cylinder. Fig. 8 is a side elevation of'a modified form of the same; Fig. 9, a central, longitudinal sectionof the track at the middle, showing a device for elevating a portion thereof; Fig. 10, a sectional view of the timbers of the frame, showing the manner of connecting them, and Fig. 11, a transverse section of the parts shown in Fig. 6, on the line of the center of the conical socket therein. Fig. 12, Sheet 2, is a side elevation of one end of the press, showing the arrangement of the cylinder and inking device; Fig. 13, a plan view of the ink disk and contiguous parts; Fig. 14, a plan view of the'device for actuating the ink disk; Fig. 15 a front elevation of the step or bearing for the same; and Fig. 16, a detail of the bearing for the ends of the final ink-roller.

Fig. 25, Sheet 5, is a central, longitudinal section of one end of the cylinder; Fig. 26, a plan view of the same, with the gripper attached; Fig. 27, an end view of the cylinder, with the head detached; and Fig. 28 a fragmentary sectional view of the cylinder on the line of the center of a plug therein.

Similar letter of reference indicate corresponding parts.

Referring now to the drawings, the supporting frame for the bed consistsessent'ially of longitudinal beams A A resting on transverse beams A A. These are connected simply by dowel pins a, so that the timbers may be easily and quickly connected and disconnect ed. The construction is such as to give a strong, stable floor support for the iron bed U on which the type-form is placed, while in moving it is very convenient, the parts being detached by simply lifting off the upper ones,

and may then be handled separately.

On top of the beams A A rest the middle track-rails B B. These are separated at the of the track is in the socket-plate d.

ends by transverse bars B B the rails being drawn tightly against the ends of the bars.

by rod-bolts BB. Upon the ends of these middle rails abut the ends of the terminal rails B B, the inner ends resting in gains in the transverse bars B B, which rest on the bed-supporting frame, and the outer ends on terminal. floor-block A A, to which they are connected removably by dowels, as shown in Fig. 3.

To each end of the rails B B is connected a casting D, the rail fitting inside the casting, as shown in Fig. 11. By reference to Fig. 5 it will be seen that the rails meet within this casting, so that'the side flanges thereof, together with the abutting cross-bars B B afford lateral bearings for both the middle and terminal rails. Into the socket so formed the inner ends of the terminal rails slip, being attached or detached in a moment, and being held securely on all sides when in position. The upper edges of the rails are all faced with band iron 19 p 19, thus making a durable track for the cylinderE mounted to roll thereon. At the proper place for the cylinder to rest at each terminus is a depression I), which holds the cylinder until it is started down the incline of the track B by the hand of the operator.

While in the act of printing, the cylinder bears heavily on the type, as will be understood. In presses of this characteracominon difficulty has been the tendency to cut the paper and batter the type at the edge of the form as the cylinder rises upon it and leaves it. To obviate this we provide a slight elevation in the track as it approaches the edge of the form, the elevation extending to a point where the pressure of the cylinder will take effect on the first line of type, but without having to climb in order to do so. This may be a shoulder d formed on the upper face of the casting D, as shown in Fig. 8, but is preferably formed on an adjustable plate, F, having a slotf therein, whereby it may be accurately adjusted along the rail B, and fixed in place by a screw f. A larger, sectional view of the same is shown in Fig. 7. 7

As the same trouble would be experienced in the middle of the bed Wherethe two forms meet, suitable provision is made at this point to the same end. This consists in means for elevating the band-iron face of the rail'at this point. The device for that purpose is illustrated in Fig. 9. In the band-iron is a hole, and in this hole is set the shouldered head of a screw or bolt 19 having a suitable nut 19 set in a socket of the rail. By means of a screw-driver the screw may be turned and the elevation of the track at the middle accurately adjusted.

A further improvement in the construction This has a conical socketd in its upper surface adapted to engage with a corresponding conical spur on the tread of the cylinder. Inasmuch as the cylinder passes from end to end of the and braced by the band-irons c 0.

track without gearing or like continuous connection with the track, to keep it in relatively the same position respecting the type-form,it is necessary to provide some means for righting any slight variations that the cylinder may make in moving back and forth, as set forth in the Letters Patent above referred to.

The improvement consists in the applicato the rail-castings D D of socket-plates I! in corresponding inner grooves in the casting D, as in Fig. 11, and held in place by means of a set-screw d. This admits of longitudinal adjustment of the socket-plate as will be seen in Fig. 2. Opposite this plate on the other rail is a transversely adjustable socketplate d fitting in a recess in the top of the casting D. This plate is provided with slots 61 through which pass the holding screws, and by means of which the plate is adjusted sidewise. It will be noticed that the plates of the same kind are placed diagonally opposite each other on the trackl This construction and arrangement admitof a careful adjustment of the plates both longitudinally to suit the periphery of the cylinder, and laterally, to correspond with its length.

Provision has also been made for the vertical adjustment of the outer ends of the rails B, to vary the incline thereof. Under the rail is placed a bolt a with a head adapted to support the rail, and provided with a nut a seated in a socket or recess a in the fioorblock A. By turning the nut the rail may be raised or depressed at will, with the effect of correspondingly increasing or diminishing the speed with which the cylinder moves. This is specially useful, also, in truing up the frame of the press on an uneven floor, and serves furthermore to compensate any unevenness in the weight of the cylinder at the respective ends thereof.

To the outer ends of the rails BB are connected uprights G 0 adapted to support the feed table 0. The parts are strengthened The former is secured to the rail and support on the back side, with a foot connecting with the .table.

The other curves forward and-connects with the table near the forward edge. This may be simply a continuation of the iron track, and its form is such as to support the table, serve as a bumper for the cylinder at the end of its movement, and give symmetry to this part of the press.

In the figures of Sheet 2 are shown the details of a self-inking device. The heads of the cylinder E are provided with an axleE,

One of these has lateral flanges fitting 1 jam-nuts, thus permitting a careful and nice adjustment of the roll with respect to the travelers g g.

Between the tracks at each end of the frame is mounted an ink-disk I-I, adapted to revolve in a suitable bearing or step I. This disk is set on an incline, as shown, the lower edge thereof being lower than the inking-roll at any point in its movement, and the upper edge projecting considerable higher than the track. As the cylinder moves to either end of its path the inking roll is carried up the face of the ink-disk, which being supplied with ink transmits it to the roller. This in turn inks the type first after the passage of the cylinder and again in advance of the cylinder as it returns, thus giving the customary double inking of the type.

Suitable provision is also made for turning the ink-disk. On a pivot is attached to the upright C is hung an arm K, curved forward at the upper end, where it is provided with a small roll it" and a weight, as of lead, 10. To the other end of the arm is hinged a rod K adapted to slip in a bearing 10" attached to the rail B. On this rod is pivoted a dog K", weighted at the lower end, and adapted to engage with the ratchet-teeth formed on the under side of the disk. A collar it limits the backward movement of the rod K. The operation of this device is as follows: lVhen the parts are in the position shown inthe fu'll outlinein Fig. 12 the roll it rests on the rim of the cylinder, and the dog is thereby pushed forward and down the under face of the disk (the farther side). As soon as the cylinder moves away from that position the upper end of the arm K is liberated, while the pawl 1 engages with the ratchet. Now if the weight k be heavy enough, the upper end of the arm will at once fall, moving the disk under the roll h still resting upon it. In practice, however, the weight is not made sufficiently heavy for this, which would be injurious to the roll and detrimental to the proper distribution of the ink on the disk. But the instant the roll leaves the ink-disk, the weight of the upper portion of the arm K carries the pawl back, as indicated by the dotted lines, thereby turning the disk alimited distance. This distance may be regulated by moving and setting the collar It. By providing the step I with slots 1' t' the same may be vertically adjusted by the bolts t" i, see Fig. 15.

The inking device just described is automatic so far as taking the ink from the disk and spreading it on the face of the type is concerned. On Sheet 3, however, is shown the detail of a device for automatically supplying the disk with ink.

To the upper end of the floor-block A is attached an ink-fountain J. In this is mounted the fountain roll h, in the usual manner, near which is the upper edge of the disk. On the disk is mounted an independent roll h, with bearings extending from each end thereof. The backward portion of the hanger g terminates in a fork g adapted to catch the hearing at either end of this roller as the cylindermoves toward the end of its path, and thus push the roll to the upper edge of the disk and upon the fountain roller h. Having gathered a little ink on its surface thereby, it runs down the disk again by its own gravity as the cylinder moves away, transmitting the ink on its surface to the disk. In order to hold this intermediate roll from the possibility of moving endwise on the disk so as to get out of the path of the forks above referred to, the slotted guidesLma-y be provided, in which the ends of the roll shaft move. also serves as a stop for the roll in its descent. Slots Z and Z permit inclined and vertical adjustment by means of bolts Z Z, so that the roll may be made to clear the disk entirely at the lower end of its movement and allow the disk to turn. It is to be understood that these guides might be dispensed with, leaving the roll free to follow its own course down the disk. has been thought desirableto confine the roll to some extent, and the guides have therefore been added as a supplemental feature.

To keep the fountain roll supplied with ink from the trough, we provide means for automatically turning it. To its axle is secured a ratchet M, and on the swinging arm K is mounted a pawl N with a suitable spring 47..

By the oscillation of the arm the ratchet is automatically turned, imparting like movement to the roll.

To adjust the ink-trough and its roll vertically the flange of the trough may be provided with slots j 3', through which pass fastening bolts j j. r

In the figures of Sheet 4 are shown devices for changing the incline of the ink-disk and the position of the feed table. The former is illustrated in Fig. 22. In this case the step I has a socket 0 which permits the shaft H of the disk to swing a limited distance. The upper portion of the shaft has a bearing in a hole 0 of the plate 0. The plate is provided with a slot 0', through which passes a bolt 0'', the head of which is secured to the block A by a plate P screwed thereto. Besides performing its own proper function in supplying ink to the roll, the disk serves in an important degree to retardthe cylinder as it approaches the end of its track, and bring it gradually to a state of rest. This is due in large measure to the inclination of the disk, so that by changing the incline of the disk the resistance is varied. This incline of the disk also aids in the starting of the cylinder, owing to the weight of the roll and its connections traveling down it. Itis to be noted, further that the automatic inking devices above described all serve as buffers to the cylinder, and tend to stop it at the end of its path without the sudden shock which might at times take place without them.

We provide for the adjustment and easy removal of the feed table 0 by making slots 0" This was the original intention, but it The guide IIO in the brackets c and c, and connecting the table thereto by thu nib-screws c' c.

In the figures of Sheet are illustrated the details of the cylinder and grippers. The cylinder is composed of straight staves E E, grooved at the edges and connected by strips of hoop or band iron 6 e. The joint should also be closed with white lead, pine tar and resin, or other like substance to render the same water tight. For the same purpose the inside of the cylinder is coated with a pitch composed of tar and resin. Over the ends of the wooden cylinder thus made are fitted neatly the iron heads E E. These have an axle E to which is secured a hand-wheel T (shown in Fig. 1, Sheet 1). The heads also have an overlapping annular flange E',

which is turned perfectly true inside and out with a suitable taper inside, the outer faces of said flanges forming the tread of the cylinder on the tracks before described. Each of the head-flanges is provided with the conoid e, the purpose of which has been already described. These heads are bolted on the ends of the cylinder by suitable rod-bolts e" e, and are leaded or pitched to make a water-tight joint in the same manner as the staves. Our object in making the cylinder tight is to prevent the escape of dust, when the cylinder is filled with a dry substance, or liquid, when filled with water or other liquid. The advantage of this construction will be apparent when it is understood that a cylinder filled with scrap-iron and the like ordinarily weighs as much as all the rest of the press combined. It is therefore desirable to so construct the cylinder as to admit of the purchaser filling it, and thus avoid paying first class freight on dead weight of comparatively inexpensive material. The difficulty is obviated by filling the cylinder with water, or sand, or both, when it reaches its destination. To this end, the side of the cylinder not covered by the tympan blanket is provided with one or more plugs S, large enough to admit the filling material. To opposite sides of the cylinder are connected the grippers Q Q. These consist of a shaft Q, preferably of square material, with bearings turned at the ends and mounted in boxest 25. At intervals the shaft is slotted or inortised, and in these mortises are fitted the gripper blades q q. At least one of these should extend some distance back of the shaft and bear under a contractile spring 5, which thus tends to raise the points of the gripper blades. On the other side of the shaft is a button R, the lip 'r of which may be swung over the blade by the hand of the operator, and thus hold the gripper down upon the paper. On the release of this button the gripper of course fiies up automatically and releases the paper.

Fig. 27 represents the relative position of the parts as the cylinder approaches the bed B. The blades (1 are adjustably secured to the shaft by set-screws q. The length of these blades, and their adjustment in the shaft renders it possible to adapt the cylinder to the printing of varying sizes of paper without shifting the position of the boxes it. Thus, supposing that in the position shown in the drawings, the grippers are adapted to hold an eight column paper, by extending the blades to their full limit it may be possible to print a six column paper, without disturbing the shaft bearings, the blanket, or any other parts of the cylinder or its covering.
