PRINTING-PRESS.

Application filed February 27, 1920.

An object of the invention is to provide a simple, inexpensive and eflicient printing press, whereby sections of ribbon or tape of difl'erent lengths and widths can be printed simultaneously on the press.

Another object of the invention'is to provide a press so arranged, that the result of the printing on the ribbon is at all times before the operator of the press, and does not require the stopping of the press for the purpose of inspecting the work.

With these and other objects in view, the nature of which will more fully appear as the description herein proceeds, the invention consists in the novel construction, combination, and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar. characters of reference indicate corresponding parts in all the views.

Referring to the drawings, 7 is the frame, in which the supporting drum 8 is mounted to revolve; ,The frame 7 also carries pairs of rollers 9 at the front and rear ends of the Specification of Letters Patent. Patented Now 23, 1920.

frame. A 'bed' 10 is mounted on the pairs of rollers 9 so that it also rests on the drum 8.; I

the said drum 8 being adapted to take up the pressure which is applied to the bed. A type carrying plate 11 is mounted on the bed 10, suitable means being provided on the v bed and plate for securing one to the other.

The frame 7 hasuprights 12 which receive the bearings of the D roller 13. The bear ings 14 of the D roller are mounted slideably in the uprights, and the direction of the sliding motion of said bearings is in a plane passing through the axis of the D roller and the drum 8. In consequence, the pressure applied by the D roller to the bed 10 is taken up bythe drum '8. The D roller is" actuated by means of arms 15 disposed to one side of the frame as best shownin Fig. l

The frame 7 supports a receptacle 16 at the rear end of same adapted to carry the rollers of tape 17 whichiare to be printed .upon. The ends of the ribbons of the rolls located in the receptacle 16 are passed over a roller 18, revolublymounted in a frame 19, which is attached to the uprights 12 of the frame 7 and extends rearwardly of the press. From the roller 18 the tape passes over awooden brace 20, which. is secured to the. frame 19. This brace 20 is adaptedto receive pins.21, which provide the desired spacing between the rows of ribbons to be printed upon. 1 (SeeFigQQ) QThe ribbons then pass over the D roller. ,From 'the Q) roller the tapes arethreaded'through t gripping device22, and fromthere over a roller 23,1which revolves continuously in the frame 19 in thei direction indicated i arrow in Fig. 1. The means for revolving the roller 23 are not showninthe drawings. The'grippingdevice 22 ismounted to slide in the frame 19, the sliding .rnotion being mp r e there y t e dl t us h me u a r zcl s, le e .2 Wh Qh E i connected; to the gripping devieeby links 25, said lever 2 i-"being fulcrumedqon the r m 7 19 ee n 6.) t e sh ter arm 26 of said lever 24 beingengaged between two pins 27 adjustably mounted in a A plate 28.which is rigidly secured to the bed 10. By varying the relative position of the pins 27 it is possible to vary the stroke of the bed 10, in consequence, varying the quantity of slack of tape 17 throughthe medium of the extension 29 of the bed 10.

' Theframe 30 of 'thegripping device 22 carries two alining shafts 31, each provided.

: effect of the jaws upon the tapes.

at its outward extremity with a rocker arm 32; the ends of the arms 32 being provided with rolling pins 33, each adapted to engage a corresponding cam track 84 which is hinged at 35 to the frame 19. The track 3st has a portion 36 adjustably mounted thereon (see Fig. 2) whereby the operative length of the track may be varied.

Each of the shafts 31 carries a jaw 37 constrained to move with its shaft 31 and rocker arm 32. The jaws 37 are maintained against their corresponding stops 38, by a corresponding spring 39. The movement of the jaws 3? toward the bottom 40 of the .i'i'rame 30 is produced by the cam tracks 34 when the roller pins 33 of the rocke'r arms are operatively engaged therewith.

The bottom 40 of the frame 30 is preterably provided with groove ell, adapted to receive the ends of the jaws 37 and bind the tape between the bottom and the jaws, and thereby prevent the tape from slipping when the gripping device is movedrearwardly by the motion oi the lever 2 By varying the operative length of the cam tracks 34, the amount of tape fed is varied accordingly, although the jaws 37 will always engage the tape at the time the roller pins 83 reach the top oi the track, 34. (See Fig. 3). The length of the time during which the engagement is maintained between the jaws and tape depends on the length of the tracks, which as previously stated, are adjustable.

As the gripping device 22 slides forward "the rocker arms 32 will ride under the cam track 34 (see Fig. 2) and raise the said track 3% when passing the cam ends of same, and allowing the said track to drop to the original position onto the frame 19, to be in a position to engage the rolling pins 33 of the rocker arms 32, when the grippingdevice moves rearward. The engage ment oi" the jaws 37 with the bottom 40 of the frame 30 is best illustrated in Fig. 3.

The bottom 40 of the frame '30 carries a wooden bar 42 into which pins 43 maybe placed to maintain thedesired spacing between the rowsoi tapes, as best shown in 1* The ends of the jaws are provided with slits' l l to make the ends of the jaws more flexible and to increase the gripping This arrangement also permits the proper'gripping by the device oi tapes of different thicknesses;

By providing independently operable jaws .tape being printed upon when the track is longenior the gripping" device operating .1: A ,a IIOIII the longer track will. debit greater lengths of tape sections. It may be here remarked that the extension 29 or" the bed is only to provide suiiicient slack "for the gripping device, and that slack is always slightly in excess of what the maximum debit of the gripping device maybe.

As the l) roller is revolved to bring the tape into engagement with the type carry ing plate 11, the bed is moved rearward by the engagement of the arm 45 with the projection 46 of the bed, the gripping device slides forwardly without engaging the tape. The movement of the bed rearwardly pro; duces slack in the tape 17, by pulling it from the rollers carried in the receptacle 16. It cannot pull on the tape located above the bed for a part of it is pressed by the E3 roller against the type. As the i) roller is returned to i.ts initial position, the bed is moved forwardly by the weight 41:5

and causes the gripping device to slide rear- The tapes fed by the gripping maintain the tapes between the .D roller and the said roller 23 taut.
