i'NxINe MEGHANIS'M.

Application led December 27, i923. Serial No. 682,956.

The invention relates to an inking mecha# nism or device and among its many useful applications has particular utility in connection with a machine for endorsing or otherwise marking checks or the like.

My invention contemplates provision of an improved inking device or mechanism and has for' its objects: to provide an inkl ing mechanism composed of few parts simply Iand compactly arranged whereby convenience and accuracy in the operation thereof is insured; to provide an inking mechanism which may be readily and convenientlyv assembled within or removed from a check endorsing machine or the like; to provide an inking mechanism so designed as to prevent the accumulation of a superfluous quantity of' ink on the inking roller and in which the continuous feed of the proper amount of ink to the inking roller is-definitely effected;

to provide 'an inking mechanism characterized by the provision of inl; supply con# trolling elements which 'may be conven4 iently adjusted to increase or decrease in quantity the continuous supply of ink -to the inking roll.

In addition to the general objects recited above, the invention includes among its advantages, such other improvements and advantages in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In the accompanyin drawings, forming a part of this specification, and showing, for

urposes of exemplication, av preferred orm and manner in which the invention may be out limiting the claimed invention specifically to such illustrated instance or instances:

Fig: 1 is a plan view of a portion of a check endorsing machine or the like, hav ing assembled therein an inking device or mechanism constituting a preferred embodiment of the invention. Y

Fig. 2 is a side elevation of the same.

Fig..3 is a longitudinal vertical sectional view on line 3 3 of Figil.

Fig. 4 is a transverse sectional view on line 4--4 of Fig- 2. Y

Fig. 5 is a perspective view` of the ink scraping or Adistributing element.

Referring to the drawings, "1 and 2 designate a pair of co-extending arms which are r rigidly secured at their lower ends to the employed 'and practiced, but with frame of a check endorsing machine (not shown) and having pivotally and adjustably mounted in the free ends thereof by means of stud shafts 3, 3', a second pair of arms or bracket members 4 and 5.V 'Mount- 60 ed in suitable bosses 6 and 7 in the free ends of the

members

4 and 5 and extending inwardly therefrom are a pair of supporting trunnions 8,v 8. These trunnions through the intermediary of ball bearings (not B5 shown) of which their ends are fashioned to constitute the cones, support the oppo-Y site ends of a printing or type roller 10, and

provide a substantially frictionless bearing construction for the said type roller. The printing roller 10 is adapted to cooperate with an impression roller l0L during the operation of the check endorsing machine. The printing roller 10 is further provided with a removable type plate' 11 75 carrying the fixed type l1a on its upper' surface and having a substantially rectangular aperture 12 through which projects 'the changeable data 12, contained within the roller 10, to be printed on the check and 30 which data is in alignment with said aperture when the plate 11 is positioned on the` roller'lO. The check endorsing machine o f which the present improvements may constitute a part, is preferably automatic in 86 operation and is actuated by the check or other piece of paper to be marked by the printing roller l0, the said roller 10 being actuated by the insertion of the check to be marked or endorsed by means of the feed 90 roll 11b. The particular mechanism cooperating with the inserted check and by which the intermittent rotation of the print ling roller 10 is obtained, forms the subject matter of a co-pending application Serial Number 596,728 and as the same is set forth in detail therein, win not. be further described. y

Integrally formed with the arms or

members

4 and 5 is a rearwardly extending tail 100A portion 4a having adjusting means atV its rear portion (not shown) by means yof which the

arms

4 and 5 and printing roller 10 carried thereby zmaybe properly adjusted or -positioned with respect to t e impression roller 10a. l i

Formed integrally with the inner surfaces of the members or

arms

4 and 5 and suitably positioned thereon, is a pair of oppositely disposed bosses 13 having journaled 110 thereon by means of stud shafts 1'5 a pivotally mounted supporting frame 17. The,

frame 17 is provided with a pair of upwardly extending armsA 18 yterminating in adjustable yoke members 18a forming bear-` or any preferred ink absorbing material. A

rearwardly projecting tail portion 22 of the frame 17 terminates in a socket-ed boss 23,

' which constitutes a seat for a spring-pressed plate or plunger 23a. A coil spring 24 is seated in a recess 25 formed in a boss portion 26 of the rearwardly extending tail portion l 4a of the

arms

4 and 5 and bears at its upper end against the lower side of the plate or plunger 23u. A set screw E27-is threaded into the boss 23 of the frame 17 and bears at its lower end against the upper surface of the plate or plunger 23". It will be apparent that by means of the arrangement described that any desired adjustment of the frame 17 may be effected by means of the set screw 27 to bring the inking roller 20 into` proper cooperating operation with the printing or ty e roller 10.

An ink receptac e or well -28 is provided, having depending curved arms 29 at either end terminating in hub portions which are journaled on the stud shafts 15 and 16. The ends of the ink receptacle 28 are provided with bearing portions 30 which may be of U-shape, and which bearings form journal supports for the shaft or shafts 31 of a removable ink supply roll 32. T he supply roll 32 may be of vany desired or preferred material and is rovided with a smooth surface adapted w en the roller is in position'- to be partially immersed in the ink contained within the receptacle 28. A compression spring 33 is or may be provided and is seated in a recess 34 formed 'in the frame 17 and is seated at its upper end in an oppositely disposed recess 35 formed in the receptacle 28 (Fig. 3). It will be seen by this latter described arrangement that, the spring 33 bearing upward against the receptacle 28 maintains the ink supply roller 32 in a yielding and constant rolling engagement with the inking roller 20. Thisy yielding engagement of the rollers 2 0 and 32 may be further varied to any desired extentV by means of an adjusting set screw 14 hav# infr threaded engagement in a boss 16 provided at one vend of the ink receptacle 28 and bearing atits free end against the frame 17.v

An adjustable ink scraper or member 36 'i is rovided and is seated at each end upon sultablyflattened portions of the ink receptacle 28 and. projects inwardly to adjustablyv end against the scraper and bear at their other ends against upstanding lugs 38 preferably integrally formed on tlleink receptacle 28. Adjusting screws 39 are provided having threaded engagement with the lugs 38, said screws being threaded at their inner ends into the ink scraper 36. The adj usting screws 39 provide means for properly adjusting the scraper 36 with respect to the ink supply roll 32 according to whether a thin or thick film of ink is desired on said roll. Forward movement of the scraper 36 is limited by means of one or more screws 40 passing through suitable slots or recesses 41 in the ink scraper, said screws having threaded engagement with the inli recepL tacle 28. Y

AThe operation of the improved inkingv the set screw 27 to bear with desired pressure against the printing roller 10- so as to completely engage the surface of the type contained within and on the surface of the roller 10. .The desired frictional engagement between the ink supply roller 32 and the inking roller 20 is eifectedby means of the set screw 14. This engagement is preferably such that the ink supply roller barely touches the inking roller with suicient pressure to cause the rotation of the former when the inlring roller is turned by hand.

The ink scraper 36 is adjusted by means of the adjusting screws 39 into the desired cooperative relation -with respect tothe ink supply roller 32 so as to leave a thin lilm of ink upon the surface of; the roller when the same isl rotated within the ink receptacle by means of inking roller 20. It will be apparent that the adjusted relation of the ink scraper 36 with respect to the ink supply roller may be such as to result in a thin or thick film of ink being contained on the ink supply roller according to the will of the operator, such adjustment being effected by means of thel screws 39. Y Y
