A. A. HANSCOM, OF SACO, MAINE.

INK-ROLLER.

Speccation of Letters Patent No. 20,710, dated June 29, 1858.

To all whom it may concern:

Be it known that I, ALPI-Inns A. HANS- ooM, of Saco, in the county of Yorke and State of Maine, have invented certain new and useful Improvements in Hand Inking-Rollers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nat-ure of my invention consists in suspending and adjusting the inking roller in a rolling frame in the manner that will be hereinafter described.

That those skilled in the arts may use and manufacture my invention I will proceed to describe its construction and operation.

In the annexed drawings, Figure l is a side elevation, Fig. 2 is an end view, Fig. 3 a top view of the cross frame of the carriage.

B, is the inking roller. C represents a carriage in which this roller is suspended the triangular pieces (ci d) being a p0rtion of said carriage in which are secured the small wheels (e e) 0n which the carriage rolls. Screws are secured to the upper portion of these triangular pieces (CZ CZ) which pass through the connecting crosspiece as seen in Fig. 1 and are made fast by means of nuts (o). These pieces may be made adjustable, the screw of one working in the slot (i) for the purpose of bringing the wheels nearer together so that the carriage may be adjusted to suit different sized frames for forms.

(m m) are rods, which are provided with screws (a at their upper extremity pro vided with holes at their lower extremity, into which pass the small shafts in the ends of the roller B.

(S) is a piece of metal of the peculiar form herein shown of which, s s', are part-s, and through which the rod passes.

(n) is a plate provided withascrew, which screw passes through the crosspiece C, the carriage and metal piece (S), and by means of nut (u) secures said piece, S, to the carriage. The screw of plate works in the slots, h h., thus allowing the roller to beadjusted longitudinally.

(c c) are nuts which pass over the screws (c a) and by means of which the roller is adjusted vertically.

In the operation of this roller it will be seen that the wheels (e e) roll upon the frame in which the form is placed and these wheels may be brought closer together to suit the size of the frame. The inking roller being provided with ink is lowered by means of nuts (c c) on to the type. The operator then by taking hold of the handles (g g) may roll the carriage backward and forward over the type until suiiciently inked.

The advantages of this arrangement are many: among them the following will readily occur to a practical printer:

l. The roll moves more easily over the form: because the force which propels it is not constantly pressing it more heavily upon the type, and because it touches nothing but the type, and does not fall into open spaces in the form, such as occur between the pages in a book form.

2. It prevents the too hard pressing of the types into the ink roll (when soft) and consequent inking of their sides below the face, which inking tends to make a foul impression, and has always been a perpleXity to the printer, especially in working open forms, such as blanks. By applying the ink solely to the face of the type, this roller enables the pressman to obtain a clean impression upon the paper.

3. It prevents the cutting of the composition of the roll when used on open or rule work enabling the printer to work the most diflicult forms of this sort as easily as commoln forms, and with as little injury to the rol 4. The roll will keep clean much longer; for it cannot fall upon the furniture (wood &c. by which the types are locked up) and gather upon its surface the dust or dirt thereon.

5. It saves ink; because it applies ink only to the face of the types, Where it is wanted which is not generally the case with the common roller.

6. It prevents the smutting of the margins of the paper when no frisket is used; because not inking the furniture, there is no ink thereon to smut the margins.

7. It admits of the same graduation of the pressure of the ink roll upon the ink table which it does upon the types, and may thus facilitate t-he distributing of the ink upon the roll, and prevent tearing the composition of the roll when soft and sticky.

Having thus fully described my invention what I claim is* l. The employment of the several parts specified for the purpose of adapting the carriage to different sized forms, as set forth.

2. Suspending the inking roller (B) in the rolling` carriage (C) constructed in the manner herein set forth; and regulating,

.and statoning said roller by means of screws (a a) and nuts (o c) for the purpose of making an adjustable hand roller for inking type, the peculiarities and advantages of which, are herein fully described.
