CHARLES E. ADAMSON, OF MARION, INDIANA, ASSIGNOR TO ADDRESSOGRAPH COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

DUPLICATINQMACHINE.

Application filed June 14, 1909, Serial No. 502,040. Renewed February 2, 1917.

To all whom it may concern:

Be it known that 1, CHARLES E. ADAMsoN,

a citizen of the United States, residing at litiarion, in the county of Grant and State of Indiana, have i vented certain new and useful Improvements in Duplicating-Machines, of which the following is a specificationu My invention relates to improvements in drplicating-machines, such as are used for imitating typewritten-letter work.

The primary object of my invention is the production of a simple and inexpensive machine of this character which possesses all the advanta es and the perfect printing qualities of complicated and expensive machines.

Another object of my invention is the provision of a tilting-carriage arranged for reciprocating movement over a type-bed and so constructed that by means of its tilting movement, the impression-roller may be moved toward and from the type-form on said bed so that in the movement of said carriage in one direction, the impressionroller is in contact with the sheet of paper placed upon the ribbon-covered type-form and during the movement of said roller in its opposite or return direction, said roller is elevated to travel in a higher plane, out of contact with said sheet of paper.

Another object of my invention is to so arrange and support the impression-can rings that during its forward movement, the pressure exerted by the operator in moving it forward, will naturally tend to force the impression-roller against the ribbon-covered type-form, and in drawing the said carriage backward, will naturally tend to move said impression-roller upward, away from the type-form, thereby obtaining he mprint of the typeform upon a sheet of paper laid upon the inked-ribbon during. he movement of said carriage in one direction only. a

A. still further object of my invention is to provide the carriage with a pair of guide rollers traveling and confined in a pair of guide grooves or tracks and serving as a combined pivot and rollers for the carriage, so that the latter may be moved back and forth and tilted on said rollers at any point unthin range of its movement, thus enabling post cards, letter-heads of different sizes, or any other matter to be printed upon with Specification of Letters Patent.

out compelling the operator to move the impression-roller the full length of the type-bed.

With these and other objects in View my invention consists in a type-bed, suitable guide-grooves or tracks, and a printingmember movable lengthwise of said typebed and arranged to be tilted so as to raise or lower the impression-element, as may be desired; and it also consists in the construction, arrangement, and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.

Fig. 9 is an enlarged transverse section taken on line 99, of Fig. 2.

Referring now to the drawings in detail, like letters of reference refer to like parts in the several figures.

The reference letter A designates a support, preferably formed of wood, and provided centrally with a receptacle a. in which the sheets of paper after being printed upon this improved machine, may be placed. The machine rests upon said support and comprises a frame B having a flat bed C and an upstanding flange D at each side; the edges of said flanges being round at their rear ends, as at (Z, for a purpose to appear hereinafter.

Secured to the upper edges of said flanges are retainer-strips E; each strip being curved at its rear end to conform to the curved end of the flange D to which it is secured and at its other end it is bent at a right-angle, as at e. Said retainer-strips overhang the inner faces of the flanges D and provide guide-grooves or tracks F closed at their rear ends by the curved portions of said strips, as at 6 and at their other ends bv the bent portions 6 of said strips. Each of said retainer-strips is notched out at its front end, as at G.

Set upon the type-bed is a chase H held against lateral movement by chase-retainers h, k arranged lengthwise on the type-bed and separated from the guide-grooves or tracks F by intervening spaces I. The chase retainers it, 71, consist of angle-plates screwed or otherwise fastened to the typebed and the chase-retainer 72, has a friction-strip J and a securing-strip j by means of which latter said friction-strip is held to said chase-retainer; screws or other suitable fastening-means being provided for the purpose.

K are ribbon-rollers arranged at opposite ends of the type bed, from one of which an inked-ribbon K is to be paid out to be wound upon the other; and for the purpose of accomplishing this automatically, a pawl and ratchet-feed L is provided, said feed being of any common construction.

M designates the impression-carriage which is adapted to be reciprocated on the frame and it comprises a casting having a cross-bar m connecting side-members m said side-members being notched at their front ends, as at m to receive bearing-boxes N in which are held opposite ends of a spindle at having an impression-roller n rotatable thereon. Between one end of said impression-roller and the adjacent side-member of the carriage, a distance-sleeve n is placed which surrounds the spindle 7t. Each of the sideanembers of the impression-carriage is provided with vertical bores n extending from its lower edge to the notch formed therein and the lower ends of said bores are threaded and receive threaded plugs 0, between the upper ends of which plugs and the bearing-boxes, spiral springs 0 are interposed. Said springs serve to cushion the impressi0nroller in its travel over the sheet of paper laid upon the ribbon-covered type-form so that the impression-carriage will move easily over said type-form and so that an even impression will be obtained on the paper. For the purpose of holding the impression-roller with the desired pressure against the ribbon-covered type-form, adjusting-screws P are arranged at opposite ends of the impression-carriage;

said screws being threaded through the earriage above the notches m therein and having reduced lower ends to provide shoulders p which bear against the upper edges of the bearing-boxes while the reduced lower ends thereof pass through bores 19 in said bearing-boxes and enter bores in the side members of the carriage beneath said boxes. The extent to which the bearing-boxes may be elevated by the springs 0 is therefore governed by the shoulders p on said adjusting-screws and said boxes are held against removal by the lower reduced ends of said screws. When said adjusting-screws are adjusted to hold the bearing-boxes in the desired position so as to cause the impression-roller to move over the ribbon-covered type-form with proper pressure, they are held in adjusted position by means of locknuts 39 The impression-carriage is provided with a rearwardly extending handle Q to be grasped by the operator in moving the earriage back and forth on the frame. Said carriage is also provided with two pairs of guide-rollers or wheels R, R one of each pair being at each end. The wheels R are of greater diameter than the wheels R and approximately correspond in size to the height of the guide-grooves F. Said wheels are rotatably held on stub aXleS r secured in the ends of the carriage, the axles of the wheels B being coincident, also those of the wheels R so that the carriage will travel in a straight line without binding.

The wheels R serve as pivots or fulcrums on which the carriage may be tilted, as shown in Fig. 7, and they are arranged in a vertical plane to one side but preferably in advance of the axis of the impression-roller so that when the carriage is tilted, said impression-roller is slightly elevated to relieve the same of pressure, as shown in dotted lines in Fig. 7. The wheels R by reason of their being of smaller diameter, permit the carriage to be tilted and in addition to serving as traction-wheels, they also serve as stops to limit the extent to which the carriage may be tilted.

As the handle of the carriage is in a plane in rear of the impression-roller and the rollers R are in a plane to one side or in advance of the axis of the impression-roller, the tendency in forcing the carriage forward on the frame of the machine, is to bear down upon the handle and in so doing, cause the impression-roller to be forced against the sheet of paper placed uponthe ribboncovered type-form, and during this movement ofthe carriage, the smaller guidewheels R travel in contact with the lower walls of the guidegrooves F. During the return movement of the carriage, the tendency is to draw upward on the handle while drawing the carriage backward, thus causing said carriage to be tilted until the small guide-wheels R strike the retainer-strips or upper walls of said guide-grooves, thus causing the impression-roller to be moved away from the imprinted paper. It is to be noted that the carriage tilts on :a center beneath the axis of the impression roller and within the guide grooves F.

Between the chase H and the chaseretainer h, a paper-gage S is inserted which has atone end an inwardly projecting'lip s that extends over the adjacent side of the chase and acts as a stop for the end edge of the paper. This gage may be moved lengthwise between the chase-retainer and the chase so as to bring said stop at any desired point.

A finger-guard T is provided which is angular in cross-section to provide a vertical securing-member adapted to be clamped between the securing-strip j and the chase and a slightly inclined guard-membert extending inward over the marginal portion of the inked-ribbon so that the sheets of paper placed upon the latter will extend over said finger-guard with the marginal portion of the paper separated from said guard by an intervening space F, which permits of inserting the finger beneath the extending portion of the paper so that it may be easily taken hold of in order to remove it, without possibility of taking hold of the inked-ribbon underneath the paper. This guard assures a quick removal of the paper, and as the speed of the machine is governed entirely by the dexterity of the operator in placing the sheets of paper upon the ribbon-covered typeform and removing the same therefrom, the importance of said guard will be readily understood.

The notches G formed in the front ends of the retainer-strips E permit the removal of the impression-carriage from the frame; it being simply necessary to force the carriage forward until the guide-wheels R are positioned underneath said notches, after which, upon tilting said carriage, said rollers may be passed upward through said notches and the carriage then forced forward until the pair of smaller rollers R are in line with said notches. The entire carriage can then be lifted from the frame.

The pawl and ratchet-feed L at the rear end of the frame is arranged to be actuated by the impressioncarriage so that with each rearward movement of said carriage, the inked ribbon is fed over the type-form in a manner common to machines of this type. By curving the rear ends of the retainerstrips E,they act as stops to limit the rearward movement of the carriage. The smaller pair of guide-wheels R which travel along the under side of the retainer-strips during the rearward movement, roll in contact with said curved rear ends and as the operator draws upward on the handle of the impression-carriage while pulling the same backward, it checks the further rearward movement of the carriage in a noiseless manner.
