MARVIN L. BAKER, OF ATLANTA, GEORGIA, ASSIGNOR TO WILLIAM M.

srois 'F' on NITU RE;

To all whom it may concern: i C

Be it known that I, MARVIN L. BAKER, a citizen of the United States, and a resident of-Atlanta, in the county of Fulton and State of Georgia, have invented certain new and use- 7 ful Improvements in Store Furniture, of which the following is a full, clear, and exact description, such as will enable those skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming a part of this specification.

The invention particularly relates to serving apparatus of'that class in which a roll of paper is mounted so that the web can'be drawn from thesame as it-is needed for wrapping purposes. J

It has for its object the provision of a printing mechanism whereby advertising and other matter may be impressed upon the web as the latter is drawn from the roll.

The lnventlon consists inthe novel construction, combinatlon, and arrangement of parts,

such as will be hereinafter fully-described,

pointed out in, the appended claims, and illustrated in the accompanying drawings.

I Fig. 4 is a detail view showing the inner side of one of the supporting-standards. Figs. 5 and 6 are detail views, respectively, showing a side ele 'vation and a plan of one of the brackets of the printing mechanism. Fig. 7 is a detail View showing one of the roll-supporting rods.

Fig. 8 is a longitudinal sectional view of the ink-magazine. Fig. 9 is a detail View showing the printing-roll. Fig. 10 is a detail view showing the transfer-roll.

The main frame of the machine may be of In the present instance it consists of the base 10, the standards 11, mounted onthe base, and

the top 12, secured to the upper ends of the standards. In the .inner faces of the standards are the opposite parallel grooves '13, leading from the front edges of the standards to the rear edges of the same and are inclined These grooves form elongated bearings or runways for the ends of the shaft 14, which carries the paper-roll. When the shaft carrying the 'pa- Specification of'Letters Patent. I

per-rollisin position with its ends registering with the grooves, the weight of the pa-' per-roll causes the ends of the shaft to travel toward the lower ends of their respective grooves.

- An impression-roll 15 is mounted adjacent to the lower ends of the grooves 13, with the ends of its shaft journaled in the fixed bearings 16 in the standards and in line with the said grooves. This impression-roll forms the platen with which the printing-roll coacts to form the'impressionon the web 'of paper.

the momentum imparted by the drawing off i of the web. It also engages with the impression-roll and as it is interposed between the two prevents the paper-roll from contacting. with the impression-roll.

' On the base 10 and in therear of the standards 11 and in a central position opposite to the middle part of the paper-roll are secured the brackets 18. I In the upper extensions 19 of the brackets'are the vertical slots 20, with which register the ends of the shaft of the printing-roll 21. The ends of the shaft are journaled in the bearings 22 in the lower ends of the vertically-movable rods 23, passing through the bosses 24, projecting from the sidesof the brackets 18. The rods are nor- 'mally held in a raised position by the spiral springs 25, interposed between the headsof the rods and the bosses 24. By means of this mechanism the printingroll 21 is forced against the impression-roll 15 with an elastic pressure. At the' ends of the printing-roll are the annular flanges 26 and intermediate of the latter is the depressed part 27. The typeplate 28 is secured on the depressed part 27, and the flanges 26 form bearing-surfaces for the impression-roll 15 and prevent the latter from contacting with the depressed part 27 and insure a proper engagement of the impression-roll with thetype-plate.

In'the inner ends of the bracket 18 are the horizontal slots 29, with which register thev ends of the shaft of the ink-magazine 30. The ends of the-shaft are journaled in thebearings in the inner ends of the rods 31,1 passing through the lugs 82. Interposed between the Interposed between the impression-roll and lugs and the heads of the rods are the spiral springs 33, which normally press the inkmagazine toward the printing-roll. Interposed between the ink-magazine and the printing-roll is the ink distributing or transfer roll 34, with the ends of its shaft journaled in the elongated bearing formed by the slots 29 in the brackets 18. Through the action of I the springs 33 and the intervening mechanism the ink-magazine is forced against the ink-distributing roll, and the latter in turn is pressed against the printing-roll with an elastic pressure. The ends of the distributingroll are reduced, as at 34, to receive and to form bearing-surfaces for the annular flanges 26 of the printing-roll, and the main central part of this distributing-roll fits in between the annular flanges. The relative dimensions of the flanges 26 and the reduced ends 34 are such as to prevent the main central part of the distributing-roll from contacting with the printing-roll, but which at the same time permit a proper engagement of the distributingroll with the face of the type-plate to ink the latter.

The body of the ink-magazine is a hollow cylindrical casing with apertures extending through the walls of the same. One of its ends is permanently closed, and the other is provided with a removable cap 35, screwed into the end of the casing. It is covered with a suitable fabric which will permit the escape of sufiicient ink through the apertures for the purpose of inking the type-plate. By removing the cap 35 the magazine can be readily filled with ink when desired.

A tearing-blade 36 is provided to aid in the severing of the web from the paper roll. It is carried by the arms 37, hinged to the under side of the top 12, and is normally pressed downwardly by the springs 38. The latter press the tearing-blade against the paper-roll and cause it to constantly engage with the same as the diameter of the paper-roll decreases and as the ends of the shaft 14 travel down the inclined runways 13.

A crank 39 is provided for turning the impression-roll. It is removably mounted on an end of the shaft of the roll outside of the main frame. By means of this crank the impression-roll can be rotated to aid in the preliminary insertion of the end of the Web between the different rolls, and it can also be used in printing on separated articles, such as paper bags.

The operation of the device is as follows: The paper-roll having been placed on its shaft and secured thereon by any suitable means, such as wedge-collars, is placed between the uprights of the frame with the ends of its shaft in engagement with the grooves 13. The weight of the paper-roll causes it to move down the inclined grooves until it engages with the friction-roll 17, journaled in the lower ends of the grooves.

blade 36.

The paper-roll is mounted so as to be rotated in the direction indicated by the arrows. The end of the web is passed over the friction-roll 17 and then under the impression-roll 15, from which it is carried over the paper-roll beneath the tearing- During this preliminary adjustment of the web the impression-roll can be rotated by the crank 39 to aid the adjustment. When the web is drawn from the paper-roll, the friction and impression rolls are rotated. As the printing-roll bears against the impression-roll it will be caused to rotate also, and as the type-plate passes the impression-roll the imprint will be made on that part of the web that passes between the impression and printing rolls at that time. The rotation of the printing-roll causes the distributing-roll and ink-magazine to rotate also. Through this movement the ink will be transferred from the magazine by the distributing-roll to the type-plate on the printing-roll.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is
