PRINTING ATTACHMENT FOR PAPER-BAG MACHINES.

SPECIFICATION forming part of Letters Patent No. 428,153, dated May 20, 1890.

Application iiled July 2, 1889. Serial No. 316,300. (No model.)

.To a/ZZ whom it may concern.-

Be it known that I, EDWARD STANLEY, of Bridgeport, in the county of Montgomery, State of Pennsylvania, have invented certain new and useful Improvements in Printing Attachments for Paper-Bag Machines, of which the following is a speciiication.

The purpose of the invention is to provide a new, simple, and efcient means for print= ing, marking, 01 numbering completed paper bags as they are delivered fromthe machine.

In the accompanying drawings, Figure l is a sectional view showing the delivery-rolls of a bag-machine and the printing-rolls which constitute my improved attachment; Fig. 2, a rear or end View of the same; Fig. 3, a view of the ink-fountain detached; and Fig. 4 shows in detail the edge of the type-carrying roll in section and elevation.

A B represent the delivery-rolls of any ordinary bag-machine, and X may representl a paper bag passing from the delivery-rolls through the printing-rolls C D. C is the upper friction-roll, which may have a surface covered with rubber, cloth, or any suitable material to render it more or less elastic.

D is the lower type-carrying roll, operating in conjunction with the roll C and driven at the same speed that the bag X is traveling, and makes one revolution to each bag. In the face of this roll a transverse tangential recess is formed, within which a type-holding segmental plate D is secured by a screw CZ.

E is the type-block, having thereon the numberszor letters to be printed upon the bag. In the drawings it contains the matter Standard 2. It is seated in a socket in the plate D and secured by a screw d', passing through the under side of the plate.

F is the inking-roll. It is of the same diameter and is geared to run withthe roll D. A central transverse hole or passage f is formed in it, and within this hole the inkingfountain G is secured in such position that its pad g will make contact with the typeblock E as the rolls revolve.

The body of the ink-fountain is composed of a tube G', screw-threaded at each end. One end is closed by a solid cap G2, and the other l receives an open face or ring cap G3, the open ing in the cap being preferably about ,the same width as the bore of the tube. A piece of cloth, felt, or other suitable porous or fibrous material g, placed within the ring-oap G3, is clamped at its edges between the cap and the end of the tube. IVithin the tube G is a closely-fitting cup-shaped plug II, having a number of apertures 7L in its head, and between the plug and the cloth g a suiiicient number of disks or pieces of woolen cloth or other suitable material g are placed. In filling the fountain with ink the cup His pressed outwardly against the cloth g g and the tube is filled with ink, and the end of the tube is then closed by the cap G2, which is provided with a Washer II. The centrifugal force developed by the rotation of the roll keeps the ink against the pad, and the quantity of ink upon the surface of the pad may be regulated by varying the number of cloth or fibrous disks g.

NVith this attachment bags may be marked with as great rapidity and easev as they can be delivered from the rolls A B. The face of the pad g is by the centrifugal action kept supplied with ink, and once in each revolution the pad inks the type-block, and once in each revolution of the rollD a bag is printed and delivered from the machine.

I claim as my inventionl. The combination of the type-carrying roll, the inking-roll having a passage therein transverse to its axis, and thev removable yink-carrying tube'arranged in said passage, and having an inking-pad adapted to supply ink to the type, substantially as set forth.

2. 'Ihe combination, with a roll F, having a transverse central passage f formed therein, of an ink-fountain secured in said passage, consisting of a tube having a removable cap G3 and a pad g.

3. In combination with a rotating roll or support, an ink-fountain consisting of a body or tube G', having a removable ring-cap G3, an interior perforated plug H, and adapted to hold the cloth or fibrous materialg g', substantially as set forth.

4t. In combination with a rotating roll or support, an inkefountan G, consisting of a In testimony Wheleof I have hereunto subtube G', a solid removable cap G2 closing it scribed my name. at one end and a removable l'inH-eap G3 u )on T the other end7 the perforated pllg H, andlthe EDVARD STANLEX' 5 cloth or brous material g g', forming the Witnesses:

pad and interposed between the plug and the A. R. PLACE, rng-cap- E. L. IIALLMAN.
