I 4 Claims.

Thisinvention relates to improvements in printing devices of the character designed particularly for applying printed matter to wrapping paper.

The primary object of the present invention is to provide a device for use in connection with a stand carrying a roll of wrapping paper, to apply printed matter to the paper of the roll as the same is drawn therefrom for use.

Another object of the invention is to provide an improved printing mechanism of the character described which is so mounted upon the wrapping paper roll rack that it will not interfere with the placing of new rolls of paper on the rack for use.

Still another object of the invention is to provide a printing device of the character described which may also be employed for printing upon bags or individual sheets of paper as desired.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a View in front elevation of the structure embodying the present invention shown applied to a paper roll rack, portions of the structure being broken away and in section.

Fig. 2 is a vertical sectional view taken substantially on the line 22 of Fig. 1.

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral l indicates generally a paper roll supporting rack of the type commonly employed which comprises a base bar 2, a head bar 3 and vertical side bars 5 which connect the base and head bars in the manner shown. These side bars 4 are connected intermediate their ends by the shaft 5 upon which the paper roll 5 is mounted. This structure has added thereto, for use in connection with the printing device to be described, a means for preventing the overrunning of the paper roll 6 when it is turned in drawing a strip of paper therefrom. This overrunning preventing means consists of a spool having the hub portion 1 with an integral disk 8 at one end and a free disk 9 at the other end and upon the hub I is a coil spring III which bears against the disks and normally tends to force the same apart. As the axle 5 is extended through the huh I so as to position the spool at one end of the roll 6, one of the disks will be forced against the 5 end of the paper roll while the other will be forced against the adjacent upright 4 or a spacing member placed against the upright and having the shaft 5 extended therethrough. At the other end of the roll 6 a spacing sleeve ll is'l mounted upon the shaft 5 which prevents the roll 6 being pushed by the spring Ill from. proper position. f

The structure'for printing the paper of the roll 6 is mounted upon the top bar 3 of the roll" stand and comprises a pair of substantially C- shaped brackets, each of which is indicated generally by the numeral l2 and which has the top and bottom horizontal portions l3 and M respectively and the connecting intermediate per- 20 tion' [5. These brackets are secured'in backto-back relation, as shown, and mounted between the vertical portions ll thereof upon trunnions I6, is an impression roll I! over which the end of the paper from the roll 6 is trained, as shown 25 in Fig. 2.

Secured vertically upon the top of the portion 13 of each bracket l3 are two spaced parallel standards each of which is indicated by the numeral l8. These standards serve as guides .30 for the trunnions of rolls l9 and 20. Roll l9 has the relatively long trunnions 2| which pass between the adjacent standards and which are provided upon their outer ends with the pins 22 to facilitate the engagement with either trun- .35 nion of a crank 23.

The roll l9 constitutes the printing roll and While any suitable means may be employed for securing type or other printing figures against the peripheral face thereof the preferred method 40 is to use a sleeve 2 about which are formed, adjacent the ends, the tires 25 and upon which are formed between the tires the desired printing characters. These may be in the form of type giving the name and address of, and names of 45 commodities handled by, a dealer or they may be in the form of trade-mark symbols or any other characters desired. The symbols or type carried by the sleeve 24 are of sufficient height to have their faces in the same plane as the surfaces of .50 the tires so that the proper impression will be made upon the paper body as it is drawn over the top of the impression roll I! against which the tires and the type press when the roll i9 is r tated,

for wrapping articles.

The roll 20 lies above the printing roll l9 and constitutes the inking roll, the surface thereof being covered with the proper material to hold ink and transfer it to the characters upon the printing roll cylinder. At each end of the roll 20 is a trunnion 26 which positions between the standards [8 as illustrated and as will be readily seen the full weight of the roll 20 is upon the tires 25 of the roll l9 and the weight of'both of these rolls is transferred to the impression roll l1 through the tires and the printing characters upon the cylinder 24.

In order that the impression of the type upon the paper drawn over the impression roll may be more positively or firmly made, there may be provided the weight blocks 21 which have opposite faces grooved to receive the standards 18 between each pair of which a block is located. These blocks rest upon the trunnions 26 of the inking vwhich is of an elongated character and which has vertical ribs 29-at its ends for sliding engagement between the adjacent pairs of standards l8. A wick or other suitable transferring element is mounted in the bottom of the receptacle 28 as indicated at 30, and has contact with the inking roll 20 so as to transfer ink thereto. In addition to serving as a means for continuously applying it to the roll 20, the receptacle also acts as an additional weight upon the rolls. It will, of course, be understood that there may be used a roll of the type which soaks up theink and holds it for'transferral to the printing roll so that the 'ink delivering receptacle may be done away with and replaced merely by a weight bar. It will also be obvious that while it is preferred that the additional weight be used in order to make a sharp impression upon the paper, this weight bar or receptacle 28 does not have to be employed.

In order to protect the rolls from dust, a housing 3| is provided which completely encloses the upper part of the structure, the top thereof being provided with openings 32 through which the upper ends of the standards l8 pass and by which they are connected together and held against any relative movement.

Mounted in any suitable manner adjacent the impression roll I! is a blotting roll 33. While,

Y arms 34 oscillatably connected with the trunnions l6 of the impression roll and held down against stop pins 35 by springs 36. The paper strip from the roll 6 after passing over the impression roll I! between the latter and the printing roll 'l9 passes down between the impression roll and the blotting roll 33 where any excess ink is taken up by the blotting roll and the smearing of the printed matter prevented when the paper is used Mounted upon the brackets I2 beneath the blotting roll 33 is a tear bar 31 beneath the lower edge of which the paper is drawn. This bar is shown as having arms 39 which connect it with the brackets I2 but this particular manner of mounting the bar need not be adhered to as other means may be employed without departing from the spirit of the invention. v

From the foregoing it will be readily apparent that the present printing device for paper rolls may be mounted in such a manner upon the roll supporting rack I that itwill not interfere in any manner with the'mounting of new rolls upon the rack. At the same time the end of the paper roll as it is drawn between the printing roll and the impression roll will effect the rotation of the printing roll and the printing at intervals thereon of the matter carried by the cylinder 24. When the device is in use for printing the paper as it is drawn from the roll 6, the handle 23 will be removed as the necessary rotation is given to the rolls in the manner described. However, if it is desired to use the device for printing upon paper bags, sheets of paper, or other sheets of material, the end of the roll of paper is removed from between the rolls-l1 and IS, the crank applied to one of the trunnions 2| and employed for imparting rotary motion to the printing roll I 9 while the bags or sheetsare fed through between the printing and impression rolls.

This application has been re-filed for abandoned application No. 661,965, filed Mar. 21, 1933.
