JAMES C. PARKER, OF WOODSTON, KANSAS.

PRINTING ATTACHMENT FOR PAPER-ROLL HOLDERS.

To all whom it may concern Be it known that 1, JAMES C. PARKER, a citizen of the United States, residing at WVoodston, in the county of Rooks and State of Kansas, have invented a new and useful Printing Attachment for Paper-Roll Holders, of which the following is a specification.

The invention relates to a printing attachment for paper roll holders.

The object of the present invention is to improve the construction of printing attachments for paper roll holders, and to provide a simple, efficient, and comparatively inexpensive printing attachment, adapted to be readily mounted in proper position on any ordinary paper roll holder, and capable of automatic operation by the same in removing the paper from the roll, and adapted to adjust itself automatically to the roll as the latter decreases in diameter through the consumption of the paper.

Another object of the invention is to provide a printing attachment, adapted without the use of springs to cause the printing roll to exert a relatively heavy pressure on the paper roll, and at the same time to enable the inking roll to exert a relatively light pressure on the printing roll.

The invention also has for its object to provide means for preventing the inking roll from dropping into contact with any blank portions on the printing roll, so that the entire surface of the printing roll or only a portion thereof may be utilized for holding type.

\Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that Various changes in the form, proportion, size and minor details of construction, within. the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the, drawings :Figure 1 is a front elevation of a paper roll holder, equipped with a printing attachment, constructed in accordance with this invention. Fig. 2 is a vertical sectional view on the line 22 of Fig.- 1. Fig. 3 is a front elevation of Specification of Letters Patent.

the attachment, the printing and inking rolls being held in an elevated position, so as to be out of contact with the roll of paper. Fig. 4 is a transverse sectional view. Fig. 5 is a detail sectional view of the latch for locking the printing and inking rolls in an elevated position. Fig. (3 is a detail perspective view of one end of the latch and a portion of the main slides on which the same is mounted. Fig. 7 is a detail perspective view of the horizontal supporting frame or bracket. Fig. 8 is a detail perspective view of one of the main slides. Fig. 9 is a detail perspective view of one of the auxiliary slides.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the printing attachment is applied to the top 1 of the main frame 2 of a paper roll holder by means of an approximately Ushaped horizontal frame or bracket 3, composed of spaced sides 4 and a transverse connecting portion 5, and preferably constructed of flanged metal to secure the requisite strength and lightness, and at the same time to provide opposite flanges for supporting spaced inclined guides (5. Instead, however, of supporting the guides in an inclined position by the frame or bracket, which off-sets the said inclined guides from the top of the main frame, the guides may of course be mounted directly upon the main frame in a vertical position at the upper portion thereof. The transverse connecting portion 5 is provided with perforations 7 for the reception of bolts 8 for securing the supporting frame or bracket to the top 1 of the main frame of the paper roll'holder, and the sides of the frame or bracket are provided with depending integral lugs 9, forming gage stops and fitting against the rear edge of the top 1 of the main frame, in order to position the attachment properly with relation to the paper roll 10 without having to measure the parts. The main frame 2 of the paper roll holder is composed of spaced sides or standards, connected at their upper ends by the top 1 and provided at the bottom with feet 12 to form an enlarged base, but any other desired construction of main frame may of course be employed. The roll 10 of paper is mounted on a wooden core or roll 13, which is journaled in suitable bearings 14 of the sides or standards of the main frame. Also the paper roll holder may be equipped with suitable means for cutting or tearing the paper, but as the specific construction of the paper roll holder does not constitute a portion of the present invention, and as the printing attachment is designed to be applied to various paper roll holders, further description and illus tration of the paper roll holder are deemed unnecessary.

The guides 6, which are inclined, are arranged radially with relation to the axis of the paper roll, and they are constructed of suitable metal, being provided with parallel 'front and rear side flanges 15 and 16, form 1ng grooves and receiving main slides 17, which fit snugly between the side flanges 15 and 16 which are movable upwardly and downwardly along the guides. The main slides 17 are oblong and are preferably provided in their outer faces with longitudinal channels 18 to reduce the frictional contact between the slides and the guides, and suitable anti-friction devices may be employed if desired. The guides, which are located above the plane of the bearings of the main frame, terminate short of the roll of paper, as clearly illustrated in Fig. 2 of the drawings, and they are secured at points intermediate of the ends by rivets 19, or other suitable fastening devices to the inner faces of the flanges of the spaced side port-ions of the U-shaped frame or bracket, which rigidly supports the inclined guides in their superimposed position above the roll of paper. The guides are open at their upper and lower ends so that the slides may extend below the guides and also topermit the removal of the slides from the guides.

The main slides are provided at their lower portions with opposite transversely alined bearing openings 20 for the reception of journals 21 of a printing roller 22, and they are provided in their upper portions with longitudinal grooves 23, extending downward from the upper ends of the main slides to points below the centers of the same, and forming lower shoulders or abutments 24, which are spaced from the bearing openings 20. The grooves 23, which are ar ranged at the inner faces of the main slides, form guides for supplemental slides 25, which are provided at their lower portions with transversely alined bearing openings 26 for the reception of journals 27 of an inking roller 28, located above the printing roller and adapted to supply the same with ink. The auxiliary slides 25 are oblong and are movable upwardly and downwardly in the guide grooves 23, their downward movement being limited by adjustable screws 29,

mounted in threaded openings 30 in the lower ends of the auxiliary slides, and projecting downwardly therefrom and arranged to rest upon the shoulders or lower end walls 24 of the guide grooves 23. The screws limit the downward movement of the auxiliary slides and are adapted to be set to permit the inking roller to bear against the type 31 of the printing roller with the desired pressure, and they prevent the inking roller from dropping into contact with the body portion of the printing roller at any blank spaces between the type. By this construction, there is no liability of applying ink to such blank portions of the printing matter, and liability of smearing the paper with ink is eliminated. This will enable the entire surface of the printing roller or only a portion thereof to be utilized for holding the type or equivalent means for printing the advertising or other matter on the paper as it is unreeled from the device. The adjustable screws 29 also permit the use of printing rollers of various sizes, larger or smaller printing rollers being employed according to the quantity of matter desired to be printed on the wrapping paper. The adjusting screws 29 enable the auxiliary slides, which carry the inking roller, to be raised or lowered to arrange the same at the proper elevation to cause the inking roller to occupy the proper posit-ion with relation to 'the printing roller. By means of the relative adjustment of the main and auxiliary slides, they may be arranged so as to secure the proper contact between the inking and printing rollers, when there is type in the printing roller and at the same time prevent contact between the inking and printing rollers where there is no type in order to enable blank spaces to appear in the printed matter without causing a smear. The inking roller, which may be of any de-' sired construction, is provided with a suitable absorbent pad 32, and the type or other printing means of the printing roll may be of any preferred construction and may be mounted on the printing roll in any desired manner. The main slides with which the printing roller is connected are relatively heavy and cause the printing roller to bear againstthe roll of paper wit-h considerable pressure, which is relatively heavier than the pressure of the inking roller, as the auxiliary slides are light compared with the main slides. Also the pressure of the printing roller is the result of the combined weights of the printing and inking rollers with their respective slides, while the pres sure of the inking roller is produced only by the weightof such roller and the auxiliary slides.

The nnreeling of the paper from the roll 10 rotates the latter, which, through frictional contact with the printing roller, 0p-

erates to rotate the latter, so that the type or other printing devices thereof are brought into contact with the paper and caused to print on the same. The inking roller is also rotated through frictional contact with the printin roller, and the ink is thereby caused to be dlstributed to the type. The printing roller is provided at its ends, or other convenient points with flanges 22 of rubber or other suitable material, such as spring metal, arranged to contact frictionally with the roll of paper, whereby when the paper is unreeled from the paper roll, rotary motion will be positively communicated to the printing roller and through the printing roller to the inking roller. The rings 22* cause a smooth uniform rotation of the printing roller and the type, which is preferably constructed of rubber projects sufficiently beyond the plane of the peripheries of the rings 22 to secure a proper contact with the paper. The paper roll engaging rings 22 also avoids any irregular motion of the printing roller at points or spaces Where there is no type, and prevent such portions of the printing roller from coming in contact with the paper. WVhen it is not desired to use the printing attachment, the latter is held in an elevated position, as illustrated in Fig. 3 of the drawings, by means of a latch 33 consisting of a transverse rod connected at its end portions with the main slides by plates 3% and provided at an intermediate point, preferably adjacent to one end of the main slides with a projecting sleeve 35, forl'ning a handle and adapted to enable the latch to be partially rotated to extend terminal arms 36 into slots 37 of the front flanges 15 of the fixed inclined guides 6, and to withdraw the arms 36 from the said slots. The ends of the rods are bent at right angles to form the terminal arms 36, and the main slides are provided at their frontedges with recesses 38 in which the end portions of the latch are secured by the said plates 34. The plates 34 are fastened in the recesses 38 by screws 39, or other suitable fastening devices, and they have angularly bent approxiniately L- shaped portions 40, fitted against the upper end walls of the recesses 38 and extending partially around the end portions of the latch. By this construction, the latch is secured to the main slides and it serves as a brace or connecting means for the said slides. When the terminal arms 36 are swung outward to their engaging position, as illustrated in Figs. 5 and 6, they fit against the upper end walls of the recesses 38. The upper end walls of the recesses form stops to limit the outward swing of the terminal arms of the latch, which is adapted to firmly support the main slides with the printing and inking rolls in an elevated position.

The auxiliary slides are connected by a handle 41, provided at the central port-ion with a U-shaped bend and having spaced terminal L-shaped portions 42, fitting in longitudinal grooves 43 in the upper portions of the auxiliary slides and engaging inclined openings 4% at the lower ends of the grooves 43. The L-shaped portions 42 have inclined terminal arms 45, extending upwardly and outwardly and passing through the inclined openings in the auxiliary slides and projecting beyond the same, and extending into longitudinal slots 46 of the main slides. The inclined terminal arms of the handle form hook-shaped portions, and the upper end walls 47 of the slots 46 of the main slides are inclined and extend upwardly and outwardly, whereby when the handle is grasped and lifted, the auxiliary slides will be moved upward until the projecting portions of the terminal arms engage with the inclined walls of the upper ends of the slots 4C6. The main slides will then rest upon the terminals of the handle and owing to the inclination of the parts they will be held against the outward lateral movement. This will enable the slides and the inking and printing rollers to be removed from the fixed inclined guides without liability of the parts becoming disconnected from the terminals of the transverse handle. The transverse handle also operates in the nature of a brace for spacing the top portion of the printing attachment when the device is in use, but

the main slides are preferably connected by a transverse brace 1-8, consisting of a rod having its teri'ninals bent at right angles to form arms 49', which are secured in sockets 50 in the upper ends of the main slides 17. The sockets are located at one side of the groove 23 in order to arrange the brace be yond the plane of the auxiliary slides. This brace 48 rigidly connects the upper end of the main slid es and cooperates with the handle T1, the latch 33 and the rollers in spacing the slides and in maintaining the parts of the printing attachment firmly in proper position.
