Application filed April 14,

To all to 7mm it may concern:

Be it known that I, JOHN IVHITAKER, a citizen of the United States, residing in North Wales, Pennsylvania, have invented certain Improvements in Inking Attachments for. Check-Writers, &c., of which the following is a specification.

One-object of my invention is to provide means for supplying ink to the inking roller of a check writing machine.

A further object of the invention is to provide means whereby the ink supplying means will be projected against the roller at each movement of the type cylinder.

Heretofore, the general practice has been to use a felt inking roller and when it was necessary to reink the roller it was taken out and the ink distributed over it. In many in stances, however. after the machine was used for a considerable length of time, the users neglected to reink the roller-the result be-- ing an imperfect impression-end when the roller was reinked the ink was often supplied in greater quantities than was necessary, which aused a blurred impression.

By my invention the roller is supplied with an even quantity of ink so that the impressions are always the same.

In the accompanying drawings:

Figure 1 is a side view, partly in section. illustrating my invention as applied to one form of check writer;

Fig. 2 is a perspective view of the ink reservoir;

Fig. 3 isa sectional plan view of the ink reservoir; and v Fig. 4 is a longitudinal sectional View on: the line 4-4, Fig. 3.

1 is the base of one form of check writer, having an overhanging portion 2 in which is located the type cylinder 3. This cylinder is carried by a shaft 4. and the different types on this cylinder can be brought into printing position by suitable mechanism, not shown. An impression is made by operating the handle 5, shown by dotted lines. The shaft 4 is mounted in eccentric bearings 7 and pivoted at 8 to one of these hearings is a link 9 connected to anarm 1 on a rock shaft 11, which actuates the mechanism that feeds the check, or other paper, through the machine. 7

12 is an inking roller mounted in bearings 13 secured to the casing of the machine, as

shown in Fig. 1. This roller, in the present instance, is made of felt and bears upon the type, as clearly shown in the drawings. This is the construction of one form of apparatus now in use. In order to reink this roller 12, the cap plate 14: must be removed and lnk supplied directly to the roller. This is objectionable for the reasons statedabove.

15 is a reservoir made as clearly shown in Fig. 2, having two slotted arms 16 projecting at the forward end and adapted to span the pivot pin 17 of the inking roller 12. At

the rear of the reservoir is a depending arm 18, which is connected to an arm 19 on the rock shaft 11 so that. as this shaft is rocked, thev reservoir will have a movement toward and from the roller. The reservoir is open at the forward end, as at 20, and mounted in the reservoir is a wick 21 of felt. or other suitable material. The end of the wick projects through the opening 20 at the forward end of the reservoir, as shown. The reservoir is tapered at the forward end so as to pinch the wick at this point and it is held at this end by teeth 22 formed, in the present instance, by bending down the edge of the plate 23, which is bent down at the back and forms the rear of the reservoir, and is preferably brazed to the body portion of the reservoir at the sides and rear, but it may. be made detachable. if desired. 24 is a cap, which is provided with a cork adapted to fit the filling opening of the reservoir.

I preferably make the wick 21 rectangular with a hollow center, and, in order to keep the wick in motion. and to prevent the ink settling, I provide a rod 25, which extends through the forward end of the wick and is attached to a light pring plate 26 shaped, in the present instance, as shown in Fig. 3, and which bears against the inner surface of the side walls of the wick. The outer end of the rod is bent to form a head which comes in contact with the inking roller when the reservoir is moved toward the roller. The wick, in the present instance, is longer than the reservoir, and assumes the shape shown when placed in position.

By the above construction. a considerable quantity of ink can be carried in the reservoir and the wick will supply only a given quantity to the roller. This supply will be uniform throughout the width of the roller. Every time an impression is made, the reservoir will be moved toward the inking roller,

and the wick 21 will come in contact with the surface of the roller, supplying the surface with the proper quantity of ink. By

' this construction it is almost impossible for an imperfect impression to be made on a check, or other paper, being printed.

When it is necessary to refill the reservoir, the plate 14 can be detached and the cap 24 removed, and a certain quantity of ink poured into the opening, the wick distributing the ink uniformly over the surface of the roller.

I claim:

1. The combination in a check writer, of a type cylinder; means for rotating the cylinder; a platen; means for moving the cylinder towardand from the platen; an inking roller arranged to supply ink to the type of the cylinder; a reservoir having a wick; and connections between the reservoir and the means for moving the cylinder toward and from the platen so that, when the cylinder is moved, the reservoir will be moved in contact with the roller.

2. The combination in a check writer, of a type cylinder; a roller for supplying ink to the type of said cylinder, said roller having pivot pins; a rock shaft actuated as an impression is made; a reservoir mounted on the pivot pins of the roller and connected to the rock shaft; and a wick in said reservoir so arranged in respect to the inking roller that when the rock shaft is moved the wick in the reservoir will be projected in contact with the inking roller.

3. The combination in a check writer, of a type cylinder adapted to be turned to bring certain type into alinement for printing; means for moving the cylinder to make an impression; a rock shaft connected to the mechanism and having an arm: an inking roller; a reservoir; means for guiding the reservoir; an arm on the reservoir connected to the arm on the rock shaft; and a hollow wick in the reservoir projecting through one end thereof and adapted to come in contact with the inking roller on the movement of the reservoir.

4. The combination in a check writer, of a type cylinder; an inking roller; means for moving the type cylinder to make an impression; a rock shaft connected to said means; a reservoir having forked arms; pins for guidin'g said arms; a downwardly extending arm at the rear of the reservoir; an arm on therock shaft to whichsaid arm is connected, the reservoir being open at the forward end and narrower at this end'than at the body; a hollow wick mounted in the reservoir and projecting through the open end and arranged to bear against theinking roller on the movement of the type cylinder toward the printing position; and an opening in the reservoir for supplying said reservoir With ink.

5. The combination in a check writer, of an inking roller; a reservoir movable toward and from the roller; a wick in the reservoir; and a rod extending beyond the wick and arranged to move the wick within the reservoir when it comes in contactwith the inking roller.

6. The combination in a check writer, of an-inking roller; a reservoir movable toward and from the roller; a hollow wick in the reservoir; a rod having a head at one end and extending through the wick and having a spring plate at its inner end bearing against the side portions of the wick and arranged to move the wick as the rod is actuated.
