This portion of the machine is constructed substantially as described in the prior application above referred to. The tape from the supply roll 13 passes upward and over a cross member into an inclined tape guide, which may be constructed as follows An inclined table or support 21 extends substantially the length of the side plate 12, and may be projected into grooves in the side plates 12, as clearly illustrated in Fig. 3. Slots 22 at each side, and a center slot 23, extend longitudinally of the table, substantially from end to end thereof. The function of these slots will be presently described. The table likewise is provided with a plurality of pairs of longitudinal corrugations 24,

25 and 26, which extend substantially from end to end thereof, and not only serve to stifien the table, but also receive similar corrugations 27 and 28 on the adjustable tape guiding members 29 and 30. The edges of the guidemembers 29 and 30 are turned 1nedges'of the tape 31.

' be given a capacit ward, forming recesses adapted to receive the The guide members are secured to the table 21 by means df'screws 32.v Threaded openings 33, adapted to receive the screws 32 are provided adjacent each of the corrugations 24, 25 and 26,'so that the guide members may be adjusted to accommodate any of the three widths of gummed tape in common use. If desired, the, machine may for handling more or different widths o tape than those which have been illustrated.

In Fig. 7 I have shown a modified form I of table and guide device in which the table 21 is provided with longitudinal slots 24' instead of corrugations,and the guide members 29' and 30 comprise deep corrugations, or loops, adaptedto be sprung into said slots, and thereby retain the guide members without the aid of screws.

The means provided for grippin the tape and moving it along the guide mem ers, comprise a sheet metal carriage 34 having upstanding cars 34 which are bent to form latei'al extensions or loops 35 which extend into and are slidably received in recesses 351 along the top edge ofthe frame plates 12. The ends of the lower part of loops 35 project beyond the upper' part, and are curved upwardly at 35*, asseen-in Fig. 4, to facilitate sliding of the carriage alongthe plates 12. Downwardly projectin rms 36 extend through the slots22 at tide sides of the table 21, and are connected beneath the table by an apron 37 A projection 38,, struck up from the middle of apron 37 extends upward through the center slot 23 and terminates in a flat face adjacent to the tape.

Extending between the upstanding cars 34 of the paper feed carriage is a rod 39 to which is pivoted a finger piece 40, comprising a gripping member or presser 41 overlyin the projection 38, and with pro ection 38 orming a tape gripping device. The finger piece is urged away from tape gripping position snugly, and without excessive friction, insuring easy and noiseless operation. The tape feeding member may be returned to the Fig. 1 position at the end of each feeding stroke, by any suitable means such as a coil spring 44 attached to the carriage at 45, passing around a roller 46 at the upper end of the table 21, and fixed to one of the side plates. The tape may be held against buckling or wrinkling by longitudinal guide wires 47 and 48, which pass through and are secured to a vertical flange 49 on a transverse plate 50, secured at the lower end of the machine adja cent the shear 19. The upper ends of wires 47 and 48 are similarly secured to an adjustable transverse bar 51, extending between the frame members at the top of the table 21. By providing relatively small diameter wires 47 and 48 to prevent buckling of the tape, the surface of the tape is substantially uncovered and it is easy to get to the tape to remove it if it becomes stuck in the machine, or to clean the table 21 and the tape guides if they become gummy from the tape.

Figs. 8 to 11 illustrate a double grip tape feeding mechanism, applied to this type of tape serving machine. In this embodiment of the invention, the supporting table 54 is received between but spaced from the side plates 55 and 56. The upper end 59 of the table is curved downwardly about a cross member 20 and the lower end is secured adjacent the shear by screws 60. The body of the table comprises a center section or strip 61 and outside sections 62 and 63 integral with the ends of the table with slots 681 and 691 intervening between the edge portions 62 and 63 and the center section. The outer edges of the sections 62 and 63 are bent upwardly and inwardly to form tape guiding grooves 64 and 65, and each of the table sections may be stiffened by a longitudinal corrugation 66.

The double grip tape feeding device may comprise a carriage of sheet metal constructed as follows: An apron 67 passing transversely beneath the table is shaped to conform to the configuration of the table, having corrugations 661 adapted to receive the corrugations 66, and upwardly projecting sections 68 and 69 adapted to enter the longitudinal slots 681 and 691 between the center and the outside sections of the table. The ends of apron 67 are curved upwardly and inwardly at 671 and 672 to encircle the inturned edges of the table, and terminate in upwardly extending cars 70 and 71. The carriage rides upon the table 54. Between the cars 70 and 71 extends a rod 72 on which are pivoted the downwardly extending ears 73, 74 of a finger piece 75 which is urged in a counter clockwise direction (Fig. 10) by suitable means, such as a spring 76 and is stopped by the engagement of lugs 77, 78, with parts 671 and 672 of the feed carriage. A pair of gripper members 79, 80 which may be integral extensions of the metal of the finger piece bent to form fiat'hottomed loops extending over the slots 681 and 691 toward the projections 68 and 69 of the transverse apron 6T. lVhen the finger piece is rocked about its pivot against the tension of spring 76, the tape will be firmly gripped between the gripping members 7 9 and 80 and the projections (i8 and 69 respectively. The tape is thus engaged at two difierent, transversely aligned positions and when the carriage 75 is moved down the table 54, positive and straight feeding of the tape is insured.

The tape feeding device may be returned to the upper end of the table by a spring 81 attached to a lug 82 on apron 67, and extending over a roller 83 on the frame. The movement of the feeding device by spring 81 is stopped by the engagement of an abutment 810 with apron 67.

The middle part of the tape may be guided and prevented from buckling by a guide bar 87. secured at its ends to transverse bars 85. 86, suitably attached to the frame.

It will be seen that I have provided a novel and effective means of engaging wide tape in such a way as to insure positive and accurate feeding. as well as a broadly novel and effective means of adapting a machine to tape of different widths. The invention is .not. therefore, to 'beconsidered as limited to the specific embodiments which have been illustrated and described, but is to be construed as extending to all equivalent devices falling within the scope of the appended claims.
