Specification of Letters Patent.

Patented Jan. 11, 1910.

Forest, in the county ofLake and State of; 4 .Illinois, have invented'a certain new and useful Improvement in Printing-Machines,

ecificat'ion.

and is directed to the provision of a machine adapted for ofiice use, which can be run' at comparatively high seed by an unskilled operator, and with which prints maybe produced in close imitation of typewritten work.

The invention involves the provision of a printi'n -machine having a bed on which a form 0 type is supported, an ink-ribbon coacting with the printing faces of the type, a rotatable pressure-roller, and means, such as endless carriers, for moving the pressureroller in one direction over the type and in coaction therewith to effect the printing, and then in the other direction on the opposite side of the type-form and the bed therefor to return the roller to initial position.

One object of the invention is to provide in a machine of this type improved operating mechanism whereby the machine may be operated either manually or from a source of power, the devices by which this'is ac-. complished being so arranged as to make the structure very ;compact and to permit of convenient operation. of the machine.

Another object of the invention is to provide an improved mechanism for delivering the sheets after they have been imprinted upon. This delivery mechanism includes a device adapted to engage the rear edge of a sheet after the latter has been imprinted upon and push the sheet ahead of it away from the printing position, this delivery de vice being arranged to reciprocate and being actuated in one direction by the mechanism for moving the, pressure-roller and then antomatically released and retracted by a spring.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which F igure'l is a plan view of the machine broken away and sectioned in part; Fig. 2 is an elevation broken away in part; Fig. 3 is a view in elevation of portions of the operating mechanism ta ken just inside the framemember shown in Fig. 2; Fig. 4 is a sectional elevation of the motor-driven operating device; Fig. 5 is a sectional elevation of the manual operating device; and Fig. 6 is a detail view in section on line 66 of Fig. 5.

Referring to these drawings, the machine consists of a base A, on which are mounted side-frames B, B, disposed parallel to each other. iExtending between the side t'rames and mounted for rotation in bearings therein, are two shafts C, C, connected together, so as to operate in unison, and one provided with a handle 0 for turning the two shafts. These shafts carry eccentrics, upon which is mounted the bed 0' for supporting the chase a in which the type-form c is locked in the ordinary manner. An arc-shaped member 0* is mounted upon the sideframe B and provided with a number of holes into any one of which a pin 0 may be inserted to facilitate positioning the handle 0. The mechanism above described permits of raising or lowering the bed 6 and the form of type thereon,

so as to accurately position the same, but it will be understood that any'other suitable mechanism for accomplishing this purpose may be provided. An ink-ribbon D overlies the printing faces of the type a its ends bechain lying adjacent to one of the sideframes. v

A shaft 6 is mounted for rotation in bearings formed in the side-frames and carries two sprocket-wheels e on which the chains e run. At the other end of the machine are two stub-shafts, e upon each of which is rotatably mounted a similar sprocket-wheel for one of the chains 6. The side-frames B and B may each be provided with inwardly extending flanges e and c and the roller E may have disks upon the ends thereof adapted to travel between these flanges so as to cause the roller E to move in a horizontal by power. Referring to Figs. 5 and 6, it i the side thereof adapted to be received within a similarly sha ed recess formed in the end of the handle On the side of handle F is a in f forming a pivot for a' pawl f, the emf of which is pressed by a spring f in a direction to carry it through a cut-away portion in the handle F and into a notch in the hub F, as shown in 6. lt will be seen that handle F, when rotated in a counter-clockwise direction as seen in Fig. 6, will cause rotation of hub I and ear f, thereby o erating the sprockets e an carriers a, but t at car f and hub f may be rotated in this irection, without causing rotation of handle F. On the other side 0 the machine,

the shaft e is extended through its bearing merely turnin Gear lshaft z" of an electric motor 1". fseen that'when the motor 1" is in operation,

in the side-frame B and a worm-gear H is loosel mounted on this end of shaft .e'. has a flan e h on the side thereof, the inner surface 0 which is conical-shaped. Splined on shaft e between the gear H and the side-frame B is a. clutch-member h having a conical-shaped surface corres 0nding to the interior surface of flange. provided with pads h of such material as will givea good frictional en agement between the clutch-member h an the flange h. The clutch-member it has a circumferential groove k adapted to receive pins on the ends of bifurcated arms h" of a lever hlpivotally' The mounted u n the side-frame clutch-mom r h is normally held away from the gear H in the position shown in 4,'by a s ring h arranged between the si e frame B and the lever h; but the clutch member may be moved into enga ement with the gear H by means of a ban le I pivotally mounted upon the side-frame B at the other side'of the machine, in a position convenient for the operator. The shaft a upon which "handle I is'mountedhas a crank i-to which is pivotally connected one end of a connecting rod 2', the other end of which is pivotal] connected tothe lever h. The gear H mes es with a worm i on the It will be it may be caused to actuate the machine by handle I inv a direction to move the clutc -member h against the tension of spring h into engagement with the ar H. Thus by manipulatin the handle fthe machine-may be operated %y the motor continuously or intermittently, and in the latter case by movements of any extent desired, 'and by releasing the handle I the motor is thrown out of driving relation and the machine may be operated as is desired by the handle F.

The adjacent edges of the flanges e on the side-frames of the machines are formed,

as shown in Fig. 1, to provide ways J upon which guides j, 7" may slide, and a shaft 7" extends between these guides and is mounted and lgage the rear edge of a sheet after the latter s been imprinted upon and to deliver the sheet. A sprin 1;" acts upon the shaft 7' in a. direction to epress the free end of the hook j and hold the hook in the position in which it is shown in Fig. 3, in which position further rotational movement of shaft 7' is revented bi a. suitable stop.

n the gui e j s a depend'ng finger K ada tedto be engaged by a pin is carried v by a p tek which is secured to the chain e and which plate is extended downwardly so as to provide a portion adapted to travel upon t e fiangele to cause ,pin is to move in a horizontal plane. Thus when pin it is carried into engagement with finger K b the chain e, the continued movement 0 the chain and pin will cause movement of finger K, guides j and and the parts carried by the guides, and tfur'ingthis movement a pin in on an arm k secured to the shaft j will engage and be depressed by a cam-surface on the endof a strip is secured upon the side-frame B. When pin is is depressed :thus, the shaft 7' isrotatedsomewhat, so as just after the latter has engaged the edge of a sheet and before the end of the hook comes up to theedge of the type-form. In order that this movement of the hook may be made to take-place at the proper time, the strip. is is proyided with longitudinalslots, through which screws k extend, so that by loosening the screws the strip is may be adjusted in the direction of its length. After the rod 7' has been carried to a position beyond the end of the type-form, the pin is is carried downwardly by the portion of the chain 6 to which it is a'flixed traveling around the sprocket a, and the pin is at this time disengages thefinger K,' as indicated by the dotted lines at the right of Fig. 3'. At this time, the delivery of the printed sheet has been accomplished, and means are provided for returning the delivery device to its initial position.

The guide 1' has affixed thereto one end of a cord L, the other end of which is wound.v

upon a drum I which is loose upon a short shaft Z rotatable in 'a' bearing formed in a piece 1 projecting from the side-frame -B.

Pivotally mounted on the drum is a pawl Z pressed by a spring against the teeth of the ratchet-wheel I mounted upon the shaft 1'.

To the shaft Z is fixed one end ofa spiral spring Z, the other end of which is fixed to a pin 1 upon a plate l which is rigidly secured to the arm I. Thus. when the delivery device is moved to the left in Fig. 1, the cord L turns the drum Z anduby means of the pawl and ratchet winds up the spring Z",

so that this spring is under considerable tension when the delivery device reaches the end of its movement; then as the delivery device is released by the pin is, the spring acting through the drum Z and the cord L, retracts the delivery device to its initial position at the right of the machine, as shown in Fig. 1

The operation of the delivery mechanism will be readily understood from the foregoing description. The rollerE and the pin is are so positioned upon the chains that the pin engages finger K just after the roller E completes the printing of the impression, and as the roller is. 'returning beneath the bed to its initial position the hook 7' is moved to the left in Fig. 1, engages the rear edge of a sheet, is raised by the coaction of pin k and cam is and pushes the sheet ahead of it from the printing position to a delivery-tray 1 When the delivery of the sheet is accomplished, the finge r K is released and the hook 7' is returned to its initial position by the spring-actuated drum before the roller E is brought upwardly into position for printing another impression. The tension on the spring Z may be regulated by means of a suitable key applied to the squared end of shaft 2, it being only necessary, in order to increase the tension of the spring, to hold drum Z with one hand .While turning the shaft Z with the other.

Having now described my invention, what I claim as new therein anddesire to secure by Letters Patent is as follows bed, 8.
