UNITED STATES WILLIAM F. INMAN, OF CHICAGO, ILLINOIS.

TAPE PRINTING .AND MOISTENING DEVICE.

Application filed February 6, 1922. Serial No. 534,555.

To all whom it may concern:

a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tape Printing and Moistening Devices, ofwhich the following is a full, clear, and exactdescription;

My invention relates to improvements in tape printing and moistening devices, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a tape printing and moistening device which is adapted to use any width of tape.

A further object of my invention is to provide a device of the character, described in which the printing roller for the tape may be changed at will, whereby the reading matter on the tape may be varied.

A further object of my invention is to provide a novel inking means for the print- A further object of my invention is to provide a novel spring means for varying the pressure exerted by the printing roller on the tape.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims; I

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a side elevation of the device, Figure 2 is a section alongthe line 2-2 of Figure 1, and

Figure 3 is atop plane view of a portion of the device.-

In carrying out my invention. I'provide a casing 1 which has a tape roll receiving compartment 2 therein, and which has a water receiving compartment in the front end tlereof. The casing 1 carries 2. moistening roller 3 over which the tape 4 is adapted to be passed. It will be observed from Figures 1 and 2 that the roll of, tape 5 is carried by a shaft 6, which in turn is secured to the side wall 7 of the comparta ment 2. The tape 1 is passed through a slot 8 in the cylindrical wall of the'casing 2, is passed over a flat block-shaped portion 9 that is carried by the casing 2, and then is passed down around the roller 10, which ,is carried by the casing 1. A spring clip 11 normally keeps the tape 4 out of contact Be it known that I, WILLIAM F. INMAN,

with the moistening roller 3.

The means by which the tension on the roll 5 is varied at will, comprises a flexible disc 12 and a flexible disc 13' which are disposed on each side of the roll 5 and are loosely mounted upon the shaft 6. As clearly shown in Figure 1, the discs are each provided with a' lug 14 which is adapted to engage with a lug 15 carried by the casing 1, thereby preventing the rotation of the discs with the roll. tape 4 as being narrower in width than is the width of the casing 2. It is essential that the roll 5 be centered with respect to the casing 2, and to this end, I provide sleeves 16 which are disposed on the shaft 6 and which abut against the outer surfaces of thediscs 12 and 13. The sleeves 16 are of such length, as to center the roll 5 with respectto the casing 2. In case a roll of wider. or less width is used, the sleeves 16 may be entirely done away with or may be varied in length so as to automatically center the roll of tape. A cover plate 17 is mounted on the shaft 6, and is securely held against the peripheral wall of the casing 2 and the outer end of the sleeve 16 by means of a nut 18 which is screwed onto the threaded portion 19 of the shaft 6.. 'It will be seen from this construction that by merely rotating the nut 18. the discs 12 and 13 may be moved so as to vary the gripping force on the. roll 5. It is obvious that the greater the gripping force exerted by the discs 12 and 13 on the roll 5. the greater the force required to remove the tape 4 from the device.

The roll of tape 5 has a gummed surface,

ing roller is adapted to engage. 'A

As clearly shown ,in Figure 1, the housing may be swung from the full line position to the dotted line position, and may be rigidly secured to the block 9 by means of the pins 22 which In Figure 2, I have shown a I are inserted through openings 23 in the i 1 housing and into openings in the block 9.

The housing 20 is p'rovidedwith alined slots 24 therein which are adapted to slidably receive the trunnions 25.0f a printing roller 26.- The printing roller. 26 is yieldingly held in engagement with the tape 4 by means of a spring 27. The spring 27 is rigidly secured to a nut 28, and the nutturn is through the wall of the casing 20.

spring 27 is bent at suchran angle that. when adapted to receive a bolt 29 which projects The the. bolt 29 is rotated, it willexert a greater or less pressure against the trunnions 25.

The roller 26 is supplied with ink by means of ink rollers30 and 31 which havetheir trunnions 34 and35, respectively,'slidably disposed in slots32 and 33. The roller 31 is adapted to contact with the roller 30,

which in turn is adapted. to contact with the roller26. A spring 36 is carried by the housing and is adapted to yieldingly hold the roller 31 againstth'e roller 30. In

this manner, the rollers 31,30, and 26 are always contacting each other. A cover 37 is pivotally secured to the top of the housing 20st 38', and is adapted to normally close an opening 39 in-the housing 20. -When' it is desired to add more ink to the printing -roller 26, the cover 27 is moved about its pivot 38 so as to permit theliquid ink to be poured onto the rollers 31 and 30. It is a well known fact,'that by providing the roller between the roller '31' and the roller 26, the ink is "uniformly spread throughout the entire length of the printing roller 26. In thisvmanner, the ink carried by the-printed surface of the roller 26 is uniformly. disposed on' the tape 4Q The tape 4 is automatically centered with respect to the roller 26 bydneans of tape guides-40*which are disposed on each side of the tape and are carriedby the block 9 -(see Figures 1 and 3) Each of the guides comprisesfa strip of metal which is U shaped and which has its ends bent upwardly so as to provide tape guiding surfaces 41. It will be observed .from the drawing that two guides are mounted on each side of the housing 20 and. are disposed on opposite.

isplacedfin the water compartment (not shown) and the desired amount of tape 4; is passed over the wetting roller so as to be moistened and is .then' severed from theroll of tape by means of the cutting edge 13. As the tape at is removed from the device, it passes beneath the roller 26 and receives the inked impressions of the chanacters carried by the roller. In this way, the tape is printed as it is used, and the printing matter may be readily changed at will by merely changing the printing roller 26. As

heretofore stated, the pressure of the roller "26 on thetap'e 4; may. be varied at will by merely rotating the bolt 29.- The forcerequired to remove the tape from the device may also be varied at will merely rotating the nut 18 as has hereinbefore been de-' scribed. v I From the foregoing, it will be observed that I have provided a simple and eiiicient device in which a roll of tape is printed as it is withdrawn from the device, and in which the spring tension on the roll of tape may be varied at will. It is also to be noted that/I have provided a device in which a tape of any width may be readily used. The

device is very simple in operation and is .not likely to easily get out of order.
