"UNITED, sTATEs PATENT OFFICE.-
HARRY C. GAMMETER, OF CLEVELAND, OHIO, ASSIGNOR TO THE AMERICAN MULTI- GRAPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
DUPLICATING-MACHINE.
To all whom it may concern:
Be it known that I, HARRY C. GAMMETER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented acertaln new and useful Improvement in Duplicating-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention is designed to provide a simple and efficient printing device adapted for embodiment in a small office machine.
The machine prints with individual type mounted in longitudinal holders on one member of a couple which prints by rolling contact.
The invention is primarily concerned with --an inking ribbon and mechanism for carrying and feeding it, enabling the ribbon to travel forwardly with the type during impressions and to be drawn backward between impressions.
The invention includes also the arrangement whereby the ribbon may be fastened on its spool and whereby the used portion of the ribbon may beremoved and discarded. The aper feed operating conjointly with the ribbon feed and the means for reventing inopportune inking of the paper are also included within the present invention.
The invention may accordingly be most conveniently summarized as consistlng of the combinations of cooperating elements hereinaft-er illustrated and set out in the claims.

Serial No. 308,379.
tion in the ends of the base and are firmly fastened. to those ends by screws. This forms a very stiff and rigid frame.
B designates a shaft mounted in suitable bearings carried by the two end plates of the frame. On the end of this shaft is a crank C by which it may be rotated.
D indicates the printing drum whiclris a hollow webbed structure, as shown, having on its exterior parallel rails d, present-ing type channels between them, the type having grooves in their opposite edges whereby they may be held in such channels. The drum carries bushings cl surrounding the shaft. Mounted radially in the drum is a set screw E, adapted to extend into a reduced portion 5 of the shaft B. The head of this set screw occupies a recess (l in the drum, whereby it does not project sufficiently to interfere with the type. lVhen the set screw is loosened, the shaft B may be drawn out endwise, and the drum removed for the assemblage of type into its channels or the distribution of type already therein.
The printing drum, it will be seen, is adapted to carry a page form of assembled individual type, and by having this drum removable, the form may be removed intact and preserved for future use; or type may be assembled into, or distributed from, one drum while another is printing.
The feature of a removable holder for a page form of assembled type is claimed in my divisional application #574,660; filed Juy so, 1910.
oiiperatiug with the printing drum is an impression drum F, mounted within the base on a shaft G. The drmns D and F are geared together by the gears H and I respectively. The gear I is secured to the drum F, while the gear II is mounted on a framebushing a but is driven by lugs b on the tion of the impression platen. This enables the impression platen to'be overlaid or un derlaid' to provide for inequalities in the type. The soft covering f"'is secured at one end in a slot Pin the drum, while the other end is held by a spring bale f bending the covering into a recess 7 in the drum.
The shaft Gr of the impression platen is shown as having eccentric extensions 9 g mounted in bushings carried by the end members of the frame base. On the extension 9 is an arm J by which the shaft may berotated to adjust the impression platen with reference to the printing drum. To lock this lever J in various adjusted positions, while allowing its convenient release, I provide the ring K which seats in an annular groove in the end frame member A. The heads of screws 7c confine this ring in the groove while allowing it movement therein, and a thumb screw 70 furnishes means for clamping the ring in any desired position.- Mounted on the ring is a detent spring 10 with which the arm J is adapted to engage. A projection or pin on the inner side of this arm comes opposite an opening or depression k in the spring, holding the arm in'place. To release the arm, the spring is pressed toward the end plate of the machine.
In printing in imitation of typewritten v drum" itself,the ribbon passing around the uses considerable space in the drum, requirdrum. Such an an angement while efiicient,
chine has been designed to'make a very compact and simple structure, and I mount the .ribbon outside of the drum, using a larger portion of the drum surface for type rails.
In the present machine, I provide a spring barrel on which the ribbon P is mounted. This barrel consists of a central shaft n,
heads n and n thereon a tuben connect-.
ing these heads, and a spring or within the barrel, secured at one end to the shaft and at the other end to the headn. The shaft is freely j ournaled in the frame at one end and at the other end extends into a socket carried by a short shaft Q.- This shaft is pressed toward the drum by a spring 9 and its socket is so formed that it prevents the shaft having independent rotation. On the shaft Qis a head 9 and on the frame and the face of the head which bears against it are formed cooperating projections and recesses g Fig, 4c, holding the shaft Q against accidental displacement, while allowing adjustment of the spring by the turning of the head 9'. g
The ribbon P passes between the two drums, and at the rear thereof extends onto the receiving roll R, being held thereto by a suitable spring clip 1". This receiving rollis automatically rotated as the drums are revolved, by mechanism hereinafter explained, and thus takes up the ribbon gripped and fed forward-with the paper by ends in studs S and S, carried by the end frame members A and A. The stud S may be screw threaded in the frame, to allow the removal of the roller. The stud S is rigid with the frame and has loosely journaled on it a clutch T which may engage with the counterbore'd end of the roller. A spring 25 tends to prevent such engage ment. On the clutch T are formed teeth t which mesh with an idler V, which in turn meshes with the teeth of the main gear H.
On the stud S is a rigid flange 6 and a loose washer i which are secured by a pin against rotation. Between these washers isa plate I? journaled on 'the stud and having recesses containing balls t These balls normally occupy also recesses in the washers t and it". If the plate t be rocked on the shaft however, the balls are moved outof their recesses forcing apart the washers t and t and this forces the clutchinto en lOO gagement with the end of the roller R to cause the same to rotate with the clutch.
The plate t is shifted at the proper time to set the clutch by a rod Uconnected with the plate t at one end and at the other end with a bell crank U" which carries a roller U 'adapted to bear on a segmental cam f mounted on the impression platen. Whenthis roller U is in engagement with the lected that peripheral speed of the roller is substantially the same as that of the drums,
so that the ribbon is constantly wound in as it is fed forward by the cooperating sur-" I faces of the drums. At the same timethe positive pull of the roller R overcomes. any tendencyof the spring barrel N to cause backward slippage of the ribbon when gripped between the drums. A weak spring Ufl surrounding the rod U allows movement of the rod without jamming the clutch after the clutch is sufficiently tight.
To allow the coil of ribbon to be applied to the spring barrel without unwinding the coil, I mount it on a split sleeve n, this sleeve having one edge n doubled on itself to clamp the ribbon and having the other edge a turned inwardly to occupy a slot in the tube a preventing slipping. \Vhen the head Q is pulled endwise against the spring the spring barrel may be removed and the spool slipped into place over it.
.i In order to feed 'the paper-to the drums at the proper time, so that the paper and the ribbon will pass between them simultaneously, I provide the following mechanism. On the shaft V, rigidly mounted in the arms U and V*, are loose rollers V. Beneath the rollers are springs V carried by the frame of the machine. These springs are adaptedto bear against the under sides of the rollers and form stops for the paper which may be shoved toward the machine along the plate \V and beneath the guard \V. The rollers V being normally stationary, the paper, when shoved against the rollers, stops at the point where the springs V bear against them. As soon as the cam 7' allows the shaft V to swing downward, the rollers come into contact with the impression platen, and, rotating, draw the paper between them and the ends of the springs and then between the rollers and cidentally inking the paper'feed rolls Vf, 'I provide guardsm secured to the shaft V and extending over these rolls. The guards also hold the rollers in place.
From what has been described, it will be seen that the cam f initiates simultaneously the paper feed and the ribbon feed, enabling both the paper and the ribbon to be fed between the drums at the same speed as that of the line of type bearing on the impression platen. After the printed sheet is discharged from between the drums, the cam causes the release of the clutch T, as heretofore explained, and the ribbon winds back on to the original roller. A short section of the ribbon may thus be used over and over again until exhausted. \Vhen it is exhausted, the clip 1' which holds the end to the receiving roller is loosened, and the exhausted portion of the ribbon is cut off, the ribbon being again connected to the receiving roller. This method of operation has the advantage over using the ribbon for its full length continuously in that the impressions made by the section are more uni- To replenish the ribbon as it is used, I
provide an inking roller X which is adapted to bear directly on the type and ink them, so that the type furnish to the ribbon an amount of ink which corresponds to that which is taken off the ribbon by the impression. This inking roller may also allow direct printing, the ribbon being removed. The inking roller mayitself constitute an ink reservoir.
As shown in Fig. 7 the inking roller consists of a felt exterior a; mounted on the perforated tube m which is held by heads m a). The head adapted to receive the spring pressed bearing pin :0, as shown in Fig. 4, while the head :0 carries a gear :10, which, meshing with the main gear H, furnishes the means of rotation. The head 13 is hollow to communicate witlrthe interior of the roll, and a filling opening is provided in the head, which, when the roller is in use, is plugged by the screw w". The support for the roller allows its easy removal and for filling with ink either for direct printing or of the proper composition and color to replenish the ribbon.
It should be noted that while I have herein shown and described means for periodically reinking the fabric, such means are not claimed in this application, either broadly or in the specific form shown, but in my application No. 607,346, filed February 8, 1911, as a division hereof.
In printing matter with lines of type acting through a ribbon, it results that where the lines are short, as at the end of paragraphs and elsewhere, a portion of the ribbon is unacted upon, thus, ordinarily, leaving the ribbon comparatively fuller of ink at such points; and this inequality of inking in the, ribbon increases with successive impressions of the same matter on the same portion of the ribbon, resulting in giving a comparatively bad impression, when, with change of matter, a full line comes on such portion. For many classes of work this inequality of impression is immaterial and may be disregarded. However, to enable the very best result to be produced, I have incorporated with the ribbon printing my system of inking the type and letting it ink the ribbon. This obviates the difficulty by supplying to the ribbon ink at the exact place where it is removed, and this allows the same short portion of the ribbon to be-used over and over again, producing the same im' pression however the lines of type run. The ribbon is always in good condition unt l the fabric itself is worn out.
' The ribbon may originally be inked independently of the type or it may receive its ink solely from the type. In either case, the amount of ink impressed on the paper is even throughout the page, and thus a close imitation of typewritten matter may be made.

In a printing machine, the combination of the two members of'a printing'couple, of an inking ribbon, one end of which is carried independently of the couple, means for causing it to pass between the members during the impressing operation in the direction of feed of material printed, and means for drawing the ribbon back between the impressing operations.
