ALBERT B. DICK, OF LAKE FOREST, ILLINOIS, ASSIGNOR TO A. B. DICK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

PBINTIN G-MACHINE To all whom it may concern:

Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Lake Forest, in the county of Lake and State of Illinois, have invented a certain new and useful Improvement in Printing Machines, of which the followin is a specification.

This invention relates to printing machines and is directed to the provision of a printing machine adapted for office use, which can be run at comparatively high speed by an unskilled operator, and with which prints may e produced in close imitation of typewritten work.

In accordance with the invention, there is employed a bed on which the type are supported, an ink-ribbon adapted to overlie the printing faces of the type, an impressionroller and means for moving the type and roller relatively to effect the printing of an impression.

One feature of the invention resides in the arrangement of the lines of type with reference to the impression-roller. I have found that by so supporting the type-bed that the lines of type are disposed at a slight incline to the axis of the im )ression-roller, much superior results are obtained, in that the impressions are more uniformly printed and are free from blurring, particularly at the edge where the initial coaction of the roller and type takes place. A page-form of type may be set up in a chase in the usual way, and this chase may oe mounted upon the bed of the machine in such a manner that the lines of type extend in a direction inclined slightly to the direction of the axis of the impression-roller, preferably at an angle of about fifteen degrees. This feature of my invention is applicable to printing-machines varying widely with respect to the construction and arrargement of the parts thereof. In order that the machine may be of comparatively small size and the parts thereof impression-roller rather than the type, and to give to this roller a continuous movement carrying it in one direction in coaction with the printing faces of the type and then returning it to initial position upon the other side of the type-form and preferably below the same. For this purpose, the impression roller may be carried by chains which pass over suitable sprockets arranged at opposite edges of the bed, and if desired, in order to Patented April 6, 1909.

Serial No. 435,155.

increase the capacity of the machine, two or more such rollers may be mounted upon a single pair of chains. With the machine so constructed, I employ a bed provided with means for accurately leveling it and means for raising and lowering it in order to secure a heavier or lighter coaction of the impression roller with the type. Also, paperguides of a peculiar construction are provided for facilitating the placing of the sheets in position for printing, and improved delivery mechanism for removing the printed sheets.

The preferred embodiment of my invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of the machine broken away and sectioned in part; Fig. 2 is a longitudinal section of the machine; Fig. 3 is a side elevation, certain parts being omitted; Fig. 4 is an end view broken away and sectioned in part; Fig. 5 is a transverse section; and Figs. 6, 7, 8 and 9 are detail views hereinafter referred to.

Referring to these drawings, the machine consists of a base A, on which are mounted side-frames B, B, disposed parallel to each other. Extending between the side-frames and mounted for rotation in bearings formed therein, are two shafts O, C, on each of which are'inounted two eccentrics c. The bed D is supported upon the shafts C, C, and for this purpose is provided with pairs of downwardly-extending integral guides c, the guides of each pair extending on opposite sides of the shaft C or C. A pair of guides c is provided at each corner of the bed D, and lie adjacent to one of the eccentrics c. In each corner of the bed, is a threaded opening to receive a screw 0 the lower end of which bears upon the periphery of one of the eccentrics 0. Another threaded opening is provided in the bed D extending into the opening for the screw 0 and this opening is adapted to receive a screw 0, the end of which engages the screw 0 and locks it in any position to which it is adjusted. It will be seen that by turning any one of the screws 0 the corner of the bed in which that screw is located will be raised or lowered, so that the bed may be accurately leveled. When this is done, the screws 0 may be tightened up, so that the correct adjustment which has been found will be retained throughout the operation of the machine. The shaft C 5 as an ordinary piece of furniture.

is extended through the side-frame B and carries an operating handle d. Secured on each of the shafts C, C, just inside the sideframe B, is a crank d and the ends of these cranks are connected by a connecting rod d Secured to the outer side of the frame B is an arc-shaped piece d in which are two lines of openings (1 On the inner side of the operating handle (1 (Fig. 5), is a block in which are two pins d pressed toward the areshaped piece d by suitable springs. The ends of these pins are rounded and are adapted to enter a slight distance within the openings d in the piece d so as to hold the handle of in any position to which it is moved. These pins, however, do not enter into the openings d a sufficient distance to permanently lock the handle cl, so that by applying a little force to the handle it may be readily turned. A stop pin d suspended by a chain (1 from a pin on the side-frame B, may be inserted in any one of the openings (1* to arrest the movement of the handle (Z. Thus, by turning the handle 01 the shafts C, C may be rotated and the eccentrics will raise or lower the bed D. When the correct position of the bed has been found, the pin d may be inserted in the opening at the side of the handle (I so that if the handle is moved to the right in Fig. 3 to lower the bed, it may be moved back again to the position which was found to give the desired height of the bed D, its movement being arrested by pin (1.

The type E are set up in lines and locked in a chase e, in the usual manner. This chase, with the type therein, is positioned upon the bed D so that the lines of type will be disposed at a slight incline to the impression-roller which extends between the sideframes B, B. This position of the lines of type is best shown in Fig. 1. To facilitate arranging the type in this manner, the chase e is provided with notches in the forward edge thereof, and pins e are provided extending upwardly a short distance from the bed D, so that when the chase is placed upon the bed it may be moved forward thereon. until the pins 6 lie in these notches; when this has been done, the proper angular disposition of the lines of type will have been secured. When the lines of type are thus arranged and the impression-roller is moved into coaction with the type, the roller will engage a line of type at one end thereof, and this might result in a slight tilting of the roller if means were not provided for guarding against it. I therefore provide blocks or supports for holding one end of the impres sion-roller in the proper relation while the other end only is bearing upon the printing faces of the type. These blocks are shown at F in Figs. 1 and 5. As thus shown, they are formed integral with bars f which may be inserted in the chase and locked therein At one end, the bar f has an extension adapted to overlie the side-member of the chase e and which connects the barf with the block F. The block F is of such size that its upper face lies in the same plane as the printing faces of the type, and in setting up the type the block is so positioned that when the roller is moved into position for printing it will engage the block F at one end before or simultaneously with its engagement with the type E at the other, so that the roller will be held against movement out of the horizontal position. A block F with its bar f is arranged at each end of a page-form of type within the chase a, so that movement of the pressure-roller into and out of coaction with the type will be effected without such a tilting movement of the roller as would cause blurring of the impression, and such other blocks F may be employed at other points as may be necessary, as when a date line is set up, spaced apart from the body of the pageform of type, or when the matter set up consists of tabulations.

Secured to the chase c at one edge thereof is a paper-guide G shown in Figs. 1 and 9. This guide consists of a strip 9 slotted as shown in Fig. 1, so that it may be secured by screws g to the chase c at various positions along the side of the chase. The edge of this strip g extends down along the outer side of the side-member of the chase and has a stud fixed thereto. Secured to this stud and extending upwardly therefrom, is a spring 9 the upper ends of which engage the under side of a flange on the upper edge of the guide G, which is provided with vertically disposed slots through which screws g extend into the strip g. At its end, the guide G is bent to provide a portion which extends at a right angle to the main portion of the guide. The sheets are fed into position from a feed-board G mounted upon the side-frame B, and are positioned by moving one side edge of a sheet into engagement with the guide G and the end of the sheet at the corner thereof into engagement with the end-piece g.

Mounted for rotation in bearings formed in the side-frames, is a shaft H, on which are mounted two sprocket-wheels h. At the 0pposite end of the machine, a stub-shaft h is provided extending inwardly from each of the sideframes and each carrying a sprocketwheel 7t. Sprocket-chains 7L2 run on the sprocket-wheels it, one adjacent to each of the side-frames of the machine. The pressure-roller I is carried by these chains 7L2, it being arranged to rotate loosely upon a shaft 71, the ends of which are received in bearings formed in links of the chains. Adjacent to each end, the shaft 2' is provided with a disk i. When the pressure-roller is in coaction with the type, the disks 1' lie between guides 6 extending inwardly from the side-frames, so that these guides cause the roller I to move in a horizontal plane. A second shaft J extends between the chains 7L2, its ends being carried by links of the chains and arranged for rotation in bearings formed in those links. A hook-shaped member j is carried by a sleeve j, which is secured by means of a set-screw upon the shaft J. The links of the chains in which the bearings for the shaft J are formed are extended as shown at j in Figs. 2 and 6, and their edges are provided with flanges. These flanges are adapt ed to coact with the lower guides i in order to insure movement of the shaft J in a horizontal plane when that shaft is moving above the page-form of type. Secured to shaft J at one end thereof, is an arm K, and a spring 7c is fixed at one end to this arm and at the other to a stud Zr upon the member 3 so that the spring tends to turn arm K and shaft J upon the axis of the shaft until the arm engages the stud 7c. The arm K is adapted to coact with a cam 7c secured upon the side-frame B, as shown in Figs. 1 and 6. This cam has slots formed therein, to receive screws whereby the cam may be secured to the frame B in various positions of adjustment along the length of the frame.

An ink-ribbon L is arranged to overlie the printing faces of the type, and its ends are carried by spools Z. These spools are mounted for rotation in bearings Z secured upon the inner faces of the side-frames in any suitable manner. The bearing for one end of the left spool (Fig. 1) is shown in detail in Figs. 7 and S. A stub-shaft Z extends inwardly from the side-frame B, and has a sleeve Z loosely mounted thereon and pressed inwardly of the machine by a spring Z. Depending from this sleeve, is an arm Z the end of which normally lies in the path of a pin Z carried by one of the chains 7L2. A spring 111, fixed at one end to the finger Z and at the other to a pin m on the side-frame B, normally holds the finger Z against the pin 1%, as shown in Fig. 7. On the end of the sleeve Z ratchet-teeth Z are formed, adapted to coact with similar teeth on the end of the spool Z. Thus, as the chains are moved, the pin Z engages the end of the finger Z and. retates the sleeve Z against the tension of the spring m, and in rotating thus the sleeve carries with it the spool Z. When pin Z disengages and passes beyond the finger Z the latter is retracted by its spring on to the position in which it is shown in Fig. 7, and sleeve Z turns back independently of the spool Z, since the sleeve is caused to move away from the spool Z by the ratchet-teeth Z against the tension of spring Z After the sheets are imprinted upon, they are delivered into a tray P. As the sheets lie at somewhat of an angle to the leng th of the machine, I provide guides for .-uiding them so that they will move substantially in the direction. of the length of the machine and (Fig. l) adapted to coact with the ed; and upper surface of the sheet. The guide ,9 for the other edge of the sheet is preferably secured to the bed D and extends forwardly therefrom, as shown in Fig- 1. This guide is provided with parallel walls be ween which the sheet passes and a wall 12" (hr s. eland 1) extending between these parallel walls and arranged at an incline so as to guide the sheet into the tray P.

Preferably the chase e is closed at the bot tom thereof, as by securing the recta -.lar frame constituting the chase upon a hin sheet of metal, as shown at U in Fig. 2. in order to give the page-form of type a slight amount of resiliency, a pad of rubber ll is laid over the upper face of the bed l) and between the bed and the bottom plate 0 of the chase.

If desired, a cam-strip l may be secured to the base A of the machine (Fig; 5), in position to coact with the arm K as the latter and the shaft J are moving back below the pageform of type to initial position. strip acts on the arm I; to turn the shaft J and hold it in such a position that the hooked member is disposed in a substantially horizontal plane, as in this way the path of movement of the shaft J may be closer to the shafts C, C, and the parts of the machine more compactly arranged.

A cyclometcr S may be secure l upon the side-frame B and operated by a iinion. on the end of the stub-shaft for one of the sprockets Zr at the left end of the machine.

The machine may be operated either manually or by means of a suitable motor. in the drawings, 1 have shown the shaft l l extended throne-h its bearing; in the frame B and provided 'with a pinion Zr which meshes with a gear 7L5 carried by a suitable stubshaft on which an operating handle 71 is mounted.

l n rum'iing the machine, the operator turns the handle 7t with the ri; ht hand and feeds the sheets from the tray G to the printing position with the left hand. The sheet is properly positioned by movi it into engagement with the body and end portions of the side-guide G. The rotation of the shaft H and the movement of the chains Zt brings the roller 1 upward at the rig it end. of the machine, so that the disks i on the shaft of the roller enter between the uide-llan es i and from then on the roller l moves in a horizontal plane in coaotion with the ty ie to the left end of the machine. Just before coming into coaction with the type, the roller engages the guide G and depresses it This camagainst the tension of the spring 9" until its upper edge lies in the plane of the printing faces of the type. As the roller comes into engagement with the type adjacent to one side of the page-form, it engages at its other end. one of the blocks F, so that there is no tendency to tilt the roller 1, such as would cause blurring or uneven printing of the impression. After the roller has passed beyond the type, the hook is brought by the chains 71 to the position in which it is shown in 6. At this time, the members j are bearing upon the lower guide-flange i so that the shaft J must also move in a horizontal plane. W hen the arm K is in engagement with the stud 76, as shown in Fig. 6, the end of the hook extends a slight distance below the plane of the sheet which has been imprinted upon, so that the end of the hook is carried between the sheet and the ribbon L. Just as the end of the hook passes under the sheet, the end of the arm K engages the cam 762 and is depressed thereby against the tension of spring 7c, thus raising the end of hook and the rear edge of the impression-sheet which overlies the hook. Then, as the movement of the shaft J and the hook continues, the sheet is moved along by the hook from the printing position. In this movement, the sheet is guided by the guides 19 and p so that it falls into the tray P.

It will be seen that the adjustment provided for the cam 7.." permits of so positioning this cam that the hook will be raised immediately after its end passes under the edge of the sheet, in order to lift the end of the hook above the plane of the printing faces of the type.

As thus constructed, the machine may be run at comparatively high speed by an unskilled operator and the copies produced thereby are evenly and uniformly printed and may be in close imitation of typewritten work. If the impression is a little heavier or lighter than is desired, it is only necessary to turn the handle (Z in one direction or the other, so as to rotate the shafts C, C, and the eccentrics 0 carried thereby, andv thus raise or lower the bed D the slight amount necessary to give the desired impression. Also, if it is desired to operate the machine without imprinting upon a sheet, the handle 61 may be turned to the right a considerable distance, so as to lower the bed D so n'iuch that the roller I will not effect the printing of an impression. The positioning of the pin d in the proper hole d" in the member d permits of returning the handle (Z to the exact posi tion it had before the bed D was so lowered.

Arranging the type as herein disclosed, so that the lines thereof extend at a slight angle to the axis of the roller 1, offers a number of important advantages. In this way a sharper definition of the characters printed is obtained and the impressions are more free from blurring. Also, less pressure need be exerted upon the pressure-roller and for this reason the machine can be operated more rapidly, with less effort and without jarring when the roller engages the type. It will be seen that because of the angular arrangement of the lines of type with respect to the axis of the pressure-roller, the latter contacts at one time with type in several lines, preferably three or four when wide spacing of the lines of type is employed; therefore, the roller is in contact and is printing from a much smaller number of type at any one time than would be the case if the lines of type extended in the direction of the length of the machine or in the direction of the length of the pressure-roller, and as a consequence less pressure need. be exerted by the roller upon the type through the sheet and ribbon.
