PRINTING DEVICE.

Specification of Letters Patent.

Patented April 13, 1909. Serial No. 431,896.

To all LlilL-O'II'L Lt may 0011mm:-

Be it known that I, Wanroan L. McCAarr,

a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Printing Device, (Case B,) of which the following is a specification.

This invention relates to printing devices, and hasspecial reference to a device adapted to be used to repeatedly print the same arrangement of characters or words on a con tinuous web.

One object of the device is to provide an improved general construction of such mechamsm.

Another object of the invention is to pro vide an improved form of contact between the printing roller and the web to be imprinted.

The invention consists in general in a web actuating printing mechanism including a platen of a cylindrical form having type thereon, an in ring roller for said form together with certain im rovements in the support for the inking r ler.

e invention further consists in certain novel details of arrangement and combination of arts hereinafter fully described, illustrated in the accompan ing drawings, and specifically set forth in t 1e claims.

' In the accompanying drawings like characters of reference indicate like arts in the several views, and Figure 1 is a ongitudinal section through the device. Fig. 2 is a transverse section on the line A-A of Fig. 1. Fig. 3 is a perspective view of the bottom portion of the web roll support. Fig. 4 shows a modified form of spring for pressing the printing roller against the inking roller and p laten. Fig. 5 is a detail perspective view of the loose-jointed frame used in con nection with this invention.

The device is contained within a casing which is provided with a suitable cover 11 having erforations therein adapted to register with similar perforations in the easing 10 and receive a headed rod 12 having an eye at the small end to receive a lock 13. The casing is further provided with an opening 14 adapted to receive a web 15 and an exit opening 16 for said web. At one end of the casing there is provided a plurality of slots 17 having enlarged ortions 18.

Standards 19 having s otted upper ends, as indicated at 20, are spaced apart and re- 1 ceive a rod 21 whereon is mounted a web roll 22. In the slot above the web roll is a headed bar 23. This bar fits loosely in the slot 20 and at all times presses firmly against the web roll 22 so that it forms'a tensioning device therefor. Below the web roll 22 is mounted an arm 24 whereon is supported a web-guiding tube 25. Adjacent. the lower end of the tube .25 is a roller 26, this roller being mounted at the bottom of the web roll supports 19. The web roll suports are provided with headed lugs 27 having flattened portions 28. The heads 27 are somewhat smaller than the enlarged 0 enings 18, but larger than the lower on s of said openings, as at 17. These lugs are disposed on the bottom of the standards in commensurate relation to the slotted openings 17 and the length ohthc lugs is such that when the heads 27 are inserted in the openings 18 and pushed down to the reduced portion 17, these heads will closely engage the inner side of the casing and thus lock the standards. 19 firmly against the same.

Mounted in suitable bearings within the casing is an inking roller 29 provided with a fixedly attached gear 30. Adjacent this inking roller is a roller platen 31 provided with a similar gear 32, the platen being mounted for rotation in suitable bearings on the casing. Beneath the inking roller and platen is a tensioning roll 33 provided with a gear rigidly attached thereto, as at 34. The gear 34 meshes with the gears 32 and 30. The web 15 passing down through the tube and under the roller 26, enters the casing through the opening 14, passes under the roller 33 over t 1e platen 31 and out through the opening 16. The platen 31 and roller 32 are so arran ed as t'o-dianieter and gear ratio, that the r0 ler 33 revolves ata lower rate of speed than the platen 31. The web 15 is thus con stantly tensioned so that it will lie snugly against the platen 31. Beneath the-inking roller 29 is a drip pan 35 adapted to receive any surplus of ink that may escape from said roller.

A frame 36 is pivoted to the casing, as at 37. The pivotal connection 37is so arranged that the pivot pin is of slightly smaller diameter than the hole through which it asses. and the space between the head of t 1e pin and the casing is slightly greater than the thickness of the frame sides. The frame sides are extended upward, as at 38, and

1 ranged to receive suitable type characters.

these extensions are connected by a rod 39 loosely mounted therein.

served that by means of the looseness of the various parts one end of the frame may be 7 moved without affecting the other. At the j outer end of the frame each of the sides is provided with a slot 40 extending. downward 5 from the end of the frame and angled up- 3 ward, as at 41. The portion 41 of this slot 5 forms bearings for a printing roller 42 ar- This roller 42 is positioned to contact with the inking roll 29 and the web 15 as it is drawn over the platen. Mounted on the rod 39 is a weight 43, and arms 44 having screw- I threaded ends are attached to the sides of the frame 36. Upon the upper end of these 1 arms, and bearing against the casing cover y when the same is closed, is a rubber or other i spring 45. i

, It will now be plain that any inequality in either the inking roller or the platen 31 will i be met by the yieldable loose frame 1nounting for the roller 42 and that this roller will I be kept constantly and firmly in contact both with the inking roller and the platen or web thereon without regard to the inequality of g the surface or irregularity of movement. I

In the form shown in Fig. 4 the spring ,30 .45 of Fig. 1 is replaced with a spring 46 attached to the loose-jointed frame and the a bottom of the casing, so that it acts in a man- I ner precisely similar to the spring of the preferred construction.

In the operation of this device the Web is drawn'through the printing mechanism by any suitable means, as by that shown in the patent to inc, the application of which bears Serial No. 397,926, and which was filed October, 17, 1907. This causes rotation of the platen 31 by reason of the friction of the web thereon, and thus in turn rotates the inking i it is not desired therefore to confine the in. vention to toe exactform'lmrcin shown and rotation of the inking roller combine to rotate the printing roller and there is thus impressed on the Web a repeated series of the characters or words of the type held on the inking roller.

It is obvious that changes may be made in the form and proportions of this device withroller. The-movement of the web and the I out departing from the principle thereof, and

described, but it is wished to include all such that properly come within the scope. of the invention. a
