To all whom it may concern:

Be it known that I, OWEN LEE CHESNUTT, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Tape or Web Printing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will ena'ble others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in tape or web printing machines, and has for an object more particularly to provide a compact, inexpensive and efiicient device for association with, for instance, the rolls of wrapping paper employed in department and like stores for the wrapping of bundles, to the end that advertising matter or the name of the proprietor of the store may be successively printed upon the wrappin paper so that this matter will become wi ely circulated.

Another object of the invention resides in providing a neat and compact device for the above purposes which is capable of attachment to existing forms of wrapping paper stands and rolls, and which will at all times effectively print the paper irrespective of the size of the paper roll and which is always accessible for the purpose of making any needed repairs and for the supplying of ink to the inking roller.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Fig. 1 is a view in side elevation of a paper roll and stand illustrating the im: proved printing device associated therewith;

Fig. 2 is a plan view of the same;

Fig. 3 is an end view of the improved printing device with a portion of the stand shown in section;

Fig. 4 is a view in side elevation with parts broken away of a modified form of a paper stand and roll and with a modified form of an improved printing device applied thereto;

Fig. 5 is a section taken on the line 5-5 in Fig. 4:; and

Fig. 6 is a plan view withparts broken away and with the housing or cover removed of the bracket and parts carried thereby.

Referring more particularly to the drawin s, and for the present to Figs. 1, 2 and 3, 1 esignates a roll, for instance, of wrapping paper mounted to turn about an axis 2 in a stand or supporting frame 3.

In accordance with the invention 1 provide a printing roller 4 adapted to roll in contact with the outer periphery of the paper roll 1 in order to print desired matter upon the wrapping paper just prior to its being pulled from the roll'1. The name, for instance, of the store proprietor, or the manufacturer of specific articles in which the paper 1 is wrapped may produced upon the wrapping paper by the printing roller 4: which receives a supply of ink constantly and uniformly fro-m an inking roller 5, the surface of which lies in contact with the type surface of the printing roller 4. I also provide a blotting roller 6 which rotates in con-v tact with the periphery of the paper roll '1 in rear of the printing roller 4 so as to effectively blot the ink prior to the papers being handled in the actual wrapping of the bundle, which would otherwise be smeared and the message contained on the paper lost.

The rollers 4, 5 and 6 are provided with trunnions, journals or shafts 7, 8 and 9 which are fitted in the corners or angles of a pair of triangular plates 10 fitted at opposite ends of the rollers and provided with slots 11 and 12 for slidingly and adjustably receiving the trunnions 7 and 8, which are provided with nuts as shown to tighten against the plates. The slots 11 and 12 have their mouths or entrance portions near corners of the plates 10 and the slot 12 is directed toward the axis of the printing roller 4:, there being coil springs 13 connected between the trunnions or the nuts thereon whereby the ink roller 5v will be yieldably drawn constantly toward the printing roller and in this way a uniform supply of lnk will be constantly distributed over the type surface of the latter.

The other slot 11 in the plates 10 moves from one corner toward the center of the plate and provides for the adjustment of the printing roller 4 toward the blotting roller 6 and also inwardly of the plate so as to accommodate various curvatures in the different sizes of the paper roll 1. As this roll 1 is diminished 1n diameter as it becomes used, the rollers 4 and 6 accommodate blotting of the paper is had.

themselves to this new curved periphery so that at all times anefi'ective printing and.

Arms 14 are. ivoted substantially centrally as at 15 to both the plates 10, the

arms being preferably formed in one piece witha transverse rod or shaft 16 journaled in angle pieces or other supports 17 affixed at one side to the. stand of the paper wrapping roller. 'A coil spring 18 is wound about the shaft or rod 16, havmg one end 19 secured to the stand 3' and the other end '20 coiled about one of the arms 14. The sprmg isso tensioned and arranged as to cause the rollers to bear yieldably against the wrapping paper roll'l and to follow this roll down to or near its axis as it decreases in size through use, it beingvunderstood that the plates 10 may revolve about the pivots 15 to allow the printing rollers 4 and 6 to both simultaneously and at'all times bearagainst the wrapping paper.

Referring more, particularly to Flgs. 4, 5 and 6, a similar pyramidal arrangement of printing, inking and blotting rollers is herein shown in connection with a wrapping paper ta e or other roll 21 mounted in a slightly ifi'erent t pe of stand 22 and including as a part t ereof a top plate or bar 23 to which is removably afiixed as by the use of bolts 24 with butterfly nuts 25, the

flat upper portions 26' of brackets '27'which are twisted as indicated at 28 and extend down diagonally with respect to the paper roll21.

These brackets 27 are preferably formed of thin metal strips bent so that the diagonal portions have their thinner portions lying substantially vertically to better resist the weight imposed thereon. In the lower portions of the brackets is journaled a drum 29 over which the web or paper moves from the drum as it is bein drawn off. The printing and blotting ro lers which have been numbered similarly 4 and 6 bear against the web as it passes about the periphery of the drum 29. A slightly different form of support is shown in these figures, the triangular plates 10 being pivoted at 30 in arms 31 which are curved at their upper ends 32 and are ivoted as represented at 33 to the brackets 2 The pyramidal rollers may thus adjust themselves on the arms 31 in the manner already described and they are protected by a housing or cover 34 likewlse of a pyramidal or triangular structure provided with slots 35 secured as by nuts and bolts 36 to the arms 31. A door 37 is formed at one corner of the housin 34 near the inking roller 5 in order to give access to the same for the purpose of providing a fresh supply of ink. The door 37 is hinged as indicated at 38 and is closed by gravity, being provided with an overhanging lip 39 to afford a tight joint at its free edge. Coil springs 40 are connected between the lower portions of the ar'ms3l andthe brackets 27 for the purpose of moving the printing device as a whole toward the paperweb.

In use, the-improved printing device is associated with, for instance, wrapping paper rolls and any suitable impression may e made thereon in accordance with that given the printing roller 4. The paper is. thus printed as it is ulled from the wrap.--.

ping roll' and it-is a s0 blotted by moving against the blotting roller 6. The triangular plates in which therollers are secured may oscillate about their pivot points 15 as in the case of Fig. 1, or 30 as in the case of Fig. 4,

thus preserving the necewary active contact with the web by the printing and blotting rollers. Moreover the spring 18 in the'first formof the invention and the springs 40 in the second form move the rollers as a whole 1 against the web resulting inthe effective printing and blotting of the same.

It will be appreciatedfrom the foregoing that I have provided. an exceedingly small devicewhich may form an accessory forthe wrapping paper rolls and their stands as ordinarily used in stores without great expense and with small cost may reproduce the proprietors name or some desired advertising matter continuously upon the wrapping paper which will consequently be circulated roadcast.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope ofthe following claims.

What is claimed is: 1. In combination, a stand, a pa' er roll supported in the stand, a bracket a ed to the stand, a drum journaled in the bracket over which the paper web is led from the roll, printing and blotting rollers bearingon the web as it passes over the surface of said drum, an inking roller in. contact with said printing roller, and means for supporting and yieldin ly urging said printing and blotting rol ers against the web, substantially as described.

2. In combination with a stand having a web roll thereon, a bracket removably secured to the stand, a drum journaled in the bracket over which the web is adapted to be bracket and arm for drawing the printing and blotting rollers forcibly against said tape or web, substantially as described.

3.
