INKING MECHANISM FOB PRINTING-MACHENESJ mamas.

Specification ofitetters Eatent. NQV.1@-.914;

Application filed December a; 1913. Serial No. 80 1,6112

' improvement is fully set torth in the followspecification and, shown in the accompanying drawings.

The present invention relates to inking mechanisms for a printing machine of the type having grooved type faces such as used in check protecting or check writing ;ma-

chines, and an object of the invention is to so construct the inking roller that the latter will not be cut or worn out by contact with the type faces.

Tothis and other ends the invention con= sists in certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 isa side view of a check writing machine like that shown in my application #675,184 filed F ebruary' 3rd, 1912, parts of the casing bein away to illustrate the broken rint in w eel and the mking roller which ornis the subject of the, present application; Fig. 2 is an en-- larged sectional view of the inking roller and adjacent parts of the machine. Fig. 3 shows the roll in plan; and Fig. ishows the roll in longitudinal section and enlarged with a line of type inengagem'ent therewith.

In my application for patent aforesaid, the printing wheel 1 is mounted to turn about an axis 2 and carries on its periphery the lines of ty e 3 projecting from the wheel and grooved -or the purpose of cooperating with-the serrated die mounted below the wheel and not shown. As this printing 1 wheel rotates, the peripheral tvpe are carried over an inking roller 4-. In my applicationbefore mentioned, this roller had a smooth cylindrical surface and, being made of fibrous material, it is soon cut or worn out by the teeth of the type wheel, the grooves of which run'spirally about the wheel.

In this invention, the type Wheel and the inking roll are caused to rotate together so that the peripheral speeds of the two are the same, thus doing away with anycutting action of the gg'ooved type on the inking roller. Prefer ly this resultis cheated by depict of no What my be obtained-fora" cent: each. by addressing the "Commissioner .ribs 5 being substantially equal to the width of the lines of type so that the type engages the periphery of the inking roller between the longitudinally-extending projections.

According to the above construction, when the printing wheel 1 rotates in either direction, the successive lines of type 3 thereon enter between successive projections 5 on the inkin roller to receive ink from said roller, this being due to the roller being driven by the interlocking connection-between the longitudinally-extending projection and thelines oftype. In this way, the peripheral speed'of the roller is the same as the peripheral speed ot the printingwheel or member andcensequently the serrated faces of the lines {it} type donot cutor saw on the peripheryoi'theroller. That portion of the roller engaged-by the printing member does howeverzconform to the shape of the type faces and becomeserrated. I A further advantage of this inking rolleris that it cooperates withopposite edges of the lines of type and gives a better inking of the t e. V

iVhat I claim as my invention and desire to secure by Letters Patent isz:

1'. In a printing machine. the combination with a printing wheel having'lines of type projecting therefrom parallel with the axis of turning of the wheel, "of aninking roller cooperating with said 'printingwheel and having portions projecting. therefrom to engage between the projecting lines of type on the printing wheel to establish driving connection with the wheel.

2. In a printing machine of the class described, the combination with a movable printing member, of an inking roller cooperating therewith and formed with .projecting portions interlocking with the print ing member to he turned by the latter.
