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

PRINTING-MACHINE.

Application filed February 9, 1909.

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 following is a specification.

This invention relates to printing-machines adapted for ofiice use and so constructed that they may be run at. comparatively high speed by an unskilled operator to produce prints in imitation of typewritten work.

The invention has reference more particularly to mechanism for delivering the sheets from the printing position.

The invention involves the provision of a printing-machine having a bed on which a form of 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 therewith to effect.

the printing and in the other direction on the opposite side of the type-form and the bed to return the roller to initial position. In combination with these parts, a delivery device is employed adapted to reciprocate over the type-form and when moving in one direction to engage the edge of a sheet and move that. sheet from the printing position. This delivery device is moved automatically during the printing operation in one direction in accordance with the movement of the pressure-roller, and during this movement a spring connected to the delivery device is put under tension; at the end of this movement the delivery device is automatically released by the member which effected the movement and is retracted to its initial position by this spring.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure 1 is a plan view of the machine broken away in part; Fig. 2 is an elevation; Fig. 3 is a view of the operating mechanism of the delivery device, the view being taken just inside the side-frame shown in Fig. 2; and Fig. 4 is a detail View in section on line 4-4 of Fig. 3.

Referring to these drawings, the machine consists of a base A on which are mounted side-frames B, B, disposed parallel to each Specification of Letters Patent.

other. Extending between the side-frames and mounted for rotation in bearings formed 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 a for supporting the case 0 in which the type-form c is locked in the ordinary manner. An arc-shaped member 0 is mounted upon the side-frame B and provided with a number of holes into any one of which a pin 0 may be inserted to facilitate positioning the handle c.

The mechanism above described permits of raising or lowering bed 0 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 0 its ends being wound on the spools (Z mounted for rotation in bear ings carried by the side-frames of the machine. A pressure-roller E is adapted to coact with the page-form of type to effect the printing. This roller E is mounted for rotation in bearings formed in links of two endless chains 6, each chain lying adjacent to one of the side-frames. A shaft 6 is mounted for rotation in bearings formed in the side-frames and carries two sprocketwheels 6 on which the chains 6 run. At the other end of the machine are two stub-shafts 6 on each of which is rotatably mounted a similar sprocket-wheel for one of the chains 6. On one end of shaft 6 is a pinion c meshing with a gear mounted for rotation upon a stub-shaft projecting outwardly from the side-frame B. An operating handle 6 is secured to the gear 6 so that by turning this handle the sprocket-wheels 6 may be rotated and the pressure-roller E thereby moved in one direction over the type-form and in coaction with the printing faces of the type and then in the other direction below the page-form of type and the bed to return the roller to initial position.

The upper surfaces of the side-frames B, B are formed to provide ways F upon which guides f, f are adapted to slide. Extending between these guides and mounted for rotation in bearings formed therein, is a shaft H, on which is mounted a hook-shaped memher it. Secured to one end of the shaft H is an arm 72 having a pin 72, at its outer end. The opposite end of arm h is adapted to engage a pin if upon the guide f to arrest r0 tational movement of shaft H under the influence of a spring li secured at one end to shaft H and at the other to pin h. \Vhen the delivery device, consisting of the guides f, f, the shaft H and the member 71, is moved to the right in Fig. 3, the pin 7L2 engages a cam surface formed on the end of a strip I mounted on the side-frame B and shaft H is thereby rocked in its bearings against the tension of spring in. Strip I is adapted to be adjusted in the direction of its length and for this purpose is provided with slots 2' through which screws 2" extend.

The guide 7 has an upwardly extending flange 7', upon which is pivotally mounted a plate J. This plate is acted upon by a spring j to turn it in the direction to carry the edge of the plate into engagement with a pin j on the flange j. At its rear end, the plate J is extended laterally, as shown at K, and the end of this extension has a down wardly extending projection is (Fig. 4:). This projection is is adapted to be engaged by a pin extending laterally from a chain 70 which runs on sprocket-wheels 75 mounted for rotation on stub-shafts extending inwardly from the sidefra1ne B. One of these sprockets is connected by gears 70* with the gear 0 so that the chain 70 is operated in accordance with the operation of the chains 6 and the pressure-roller E. At its forward end the plate J is formed to provide a cam surface L, and when the delivery device is moved to the right as shown in Fig. 3, this cam surface engages a projection Z mounted upon the side-frame B and projecting over the strip I.

To the guide is secured one end of a cord M, the other end of which is wound upon and secured to a drum m rigidly mounted on a shaft m rotatably mounted in arms projecting from the side-frame B. A spiral spring m is connected at one end to the shaft in and at the other end to a plate at the side of the drum m.

In the operation of the machine, the han dle e is turned, thereby moving the roller E over the type-form to effect the printing, and at the same time the chain 7 is operated by means of the gearing above described. The operation of chain 6 causes the pin is thereon to come into engagement with the projection 70 on the plate J and the continued movement of the chain moves the entire delivery device along with it so as to carry the hook it over the type-form. This hook engages the rear edge of the sheet which has been printed, and carries the sheet along with it until the sheet falls into a delivery-tray P. Immediately after the hook it engages the edge of the sheet and before the hook reaches the edge of the typeform, the pin- 7L engages the cam surface on the strip I and is depressed thereby, thus raising the hook it above the plane of the printing faces of the type. Immediately after the delivery of the sheet has been accomplished, the cam surface L on the plate J engages the projection Z and the plate is rocked on its pivot thereby, against the tension of the spring j. This rocking move ment of plate J is sutfi :ient to raise the projection 70 above the pin Z1 so that the delivery device is released by the pin. During all this movement of the delivery device, the drum m has been rotated, thereby putting the spring m under tension, and as soon as the delivery device is released by pin is it is drawn back to its initial position by the spring m acting through the drum on and cord Id. When the delivery device reaches its initial position, its movement is arrested by a buffer m T he position of pin k upon chain L is such with reference to the position of roller E on chains 0 that the novement of the delivery device is begun immediately after the pressure-roller E has effected the printing of a sheet, and the delivery device is moved to deliver the sheet and then returned to its initial position while the pressueroller E is returning to its initial position below the page-form of type and the bed therefor.
