Application September 26, 1938, Serial No. 231,770

.2 Claims. (01. 101-226) My invention relates to means for instantaneously imprinting upon a suitable receiving stock, such as paper or comparable wrapping material, an indicium or legend, particularly an advertisement of the user of the device.

An object of my invention is to provide an inexpensive and infallible means for imprinting an advertising legend on wrapping paper being dispensed.

Another object of my invention is to provide means generally useful in a store, for imprinting a selected legend upon wrapping material such as paper or bags.

A further object of my invention is in general to improve imprinting mechanisms.

The foregoing and other objects are attained in the embodiment of the invention disclosed in the drawing, in which-- Fig. 1 is a side elevation of an imprinter in accordance with my invention, aside of the housing being removed to disclose the interior;

Fig. 2 is a front elevation of my imprinter, a part of the housing being broken away to disclose the interior; I

Fig. 3 is a fragmentary cross-section transversely of the rolls, showing paper passing through the intermeshing portions of the rolls.

In its preferred form, the imprinting device of my invention includes a housing within which is disposed a plurality of rollers having corrugated portions so that they all are rotated together under the influence of withdrawal of a paper being imprinted, taken from a roll within the casing and passing between a pair of rollers one of which contains a die periodically brought into contact with an inking mechanism and with the paper so that thepaper as it passes between the rollers is periodically imprinted, the imprinted paper being severable from the remaining paper on the roll by tearing against an edge of the enclosing housing.

Although the imprinting mechanism of my in vention is susceptible of a great deal of variation, depending upon the particular environment in which it is utilized, and depending further upon the individual requirements of special papers, wrapping materials, and the like, it has been successfully embodied in the form disclosed in the drawing, in which there is preferably afforded a support 6 which conveniently can be a counter or table within a store at a convenient location. The entire mechanism is preferably included with an attractive enclosing housing 1 preferably. fabricated of metal and readily removable to disclose the interior. Within the housing I preferably provide a pair of uprights 8 each of which is secured to the base 6 by fastenmgs piercing an outturned foot |2 thereon; The distance between the uprights 8 is preferably variable by moving the fastenings H to accommodate rolls of paper of different widths. Each of the uprights at a convenient point in itsheight is provided with a bearing slot |3, which may be supplemented by a set-screw, and carries an eX- tended shaft IS on which a paper roll I1 is mounted. By suitable manipulation the paperroll l1 may be removed and. replaced. In advance of the uprights 8 I preferably provide another pair of uprights 2|, which are subfor securing it on the table or base 6. At their upper ends all uprights carry an outturnedvflange 26 through which fastenings 21 pass to engage a top strap 28 having therein a plurality of apertures 29 so that the uprights 8 and 2| are firmly held in any of several differently spaced positions. Mounted in extensions 3| from the uprights 2| are ball bearings or other suitable antifriction bearing members 32 in which a guide roller 33 is mounted, so that a paper sheet 34 extending tangentially from the roll I1 is passed under the guide roller 33 and is established at a fixed horizontal location despite variations in diameter of the roll 1 1 as the paper is utilized.

Journaled in the uprights 2| is a feed roller 36 mounted on an extended shaft 31 which at opposite ends is disposed in anti-friction or ball bearings 38 inhibited against removal but vertically adjustable by means of set-screws 39 in the uprights, so that the roller 36 rotates freely in a selected position. This roller is supplemented by a similar roller 4| mounted on an e tended shaft 42 likewise disposed in anti-friction ball bearings 43 restrained against removal by set-screw 44 in the uprights. Adjacent its end the roller 4|, which is fabricated of rubber or similar yielding material, is provided with a sponge or cushion rubber portion or with corrugations 46 comparable to small gear teeth, which interengage and virtually intermesh with comparable corrugations 4'! on the similarly fabricated roller 36. The sheet of paper 34 is passed between the rollers" 36 and 4| so that, as the sheet is withdrawn from the roll H, the rollers 36 and 4| are rotated in accordance with the surface speed of the paper, the intermeshing corrugations sponge rubber, making the rollers turn substantially in unison.

In accordance with my invention, I provide means for imprinting upon the paper sheet 34 as it is withdrawn, and correspondingly interrupt the mid-portion of the roller 4| to provide a printing die 49 thereupon. This die 49 may take the form of a removable, rigid metallic plate held by fastenings to the roller 4|, or can be a yielding plate of rubber or comparable material formed integrally with the roller. The die revolves with the roller 4| and during its revolution is inked by contact with an inking roller 52 which occupies H the central portion of an extended shaft 53. The

inking roller 52 can either be a surface inking de'-- vice or have an ink reservoir Within itself, but in either event is effective to ink the face of the die 49 during rotation thereof and carries corrugated; or sponge rubber portions 54 which interengage with the corrugated or sponge rubber portions 2!, being adjustably retained therein by setscrews 51 and 58 so that it can be moved into appropriate inking contact with the die roller. Due to the interengagement of the inking roller and the die roller, withdrawal of the paper sheet 34 keeps the inking roller in suitable actuation so that ink is evenly spread, and the diameter of the inking roller is somewhat smaller than that of the die roller so that a thorough distribution of ink is effected.

The paper which has passed through the rollers 36 and 4|, having been suitably imprinted, passes out of the housing 1 through an elongated slot 6| in the face thereof, which is partially defined by a lower trough 62 to act as a backing or stop for the paper when the operators fingers reach into the trough to grasp the imprinted sheet.

The slot is likewise partially defined by an upper tearing edge 63 which is preferably somewhat ping paper which is purchased at the standard rate, since it is originally plain and not imprinted, yet to have a wrapper bearing an advertisement or other suitable imprint. Furthermore, it is entirely possible, by reverse rotation of the roll IT, to withdraw the sheet 34 from between the driving rolls and, by the installation of a hand crank thereupon, to feed paper bags or other individual sheets of wrapping material through the rolls in order that they may be individually imprinted.

"The transverse or lateral adjustment of the device can be varied from time to time in accordance with major or minor variations in the width of the paper rollbeing utilized, the extended shafts facilitatingthis adjustment effected by the use'of selected ones of the numerous apertures 29.

' I claim:

1. A paper imprinter comprising, a frame, a support rotatably journaled on said frame to receive a paper roll, a pair of imprinting rollers journaled on said frame, a printing die incorporated on one of said rollers, the paper being adapted to be'unrolled and drawn in a path between said rollers while being imprinted by said die, and intermeshing corrugated portions of resilient rubber on adjacent ends of said rollers within said path, said corrugated portions being comparable to small gear teeth whereby the rollers turn in unison.

2. A paper imprinter comprising, a frame, a support rotatably journaled on said frame to.- receive a paper roll, a pair of imprinting rollers journaled on said frame, a printing die incorporated on one of 'said rollers, the paper being adapted to be unrolled and drawn. in a path between said rollers while being imprinted by said die, intermeshing corrugated portions 'of resilient rubber on adjacent ends of said rollers within said path, an inking roller journaled'on' said frame for engagement with the die of said die incorporated roller and having a corrugated end portion interengaging said corrugated portion of said die incorporated roller, the said corrugated portions being comparable to small gear teeth whereby the rollers turn in unison.
