GER/MD C LOW ATTORNEY United States Patent TAPE SPLICING APPARATUS Gerald C. Low, Watertown, Conn.

Application September 30, 1953, Serial No. 383,261

11. Claims. (Cl. 154-423) This invention relates to tape splicers and more particularly to an apparatus for connecting the joints between successively fed paper strips by means of short sections of Scotch tape fed at right angles to the direction of the movement of the paper strips.

One object of the invention is to provide an apparatus adapted to join fiat, flexible paper strips in end to end aligned relationship in the same plane.

This is accomplished by attaching under the adjacent, abutting surfaces of the ends of paper tapes, short pieces of Scotch tape at right angles thereto by pressing said aligned tapes into-firm adhesive contact with the Scotch tape located t-herebeneath.

A further object is to provide a device of the above nature, which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance and very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawings, one form in which the invention may conveniently be embodied in practice.

In the drawings,

Fig.- 1 represents a perspective view of the entire tape splicing apparatus as it appears when mounted upon a table.

Fig. 2 is a cross-sectional view of the same taken along the line 2-2 of Fig. 1 showing the construction of the winding reels.

Fig. 3 is an exploded view of one of the hollow tape mandrels, and a portion of the forward drive shaft of a winding reel.

Fig. is a plan view of the tape guiding scale located in raised position alongside of the path of the tape.

Fig. 5 is a top plan view of the splicing and cutting apparatus for feeding the Scotch tape at right angles to the paper tape strips.

Fig. 6 is a side view of the same, taken along the line 6--6 of Fig. 1, with a cross-section through the table.

Fig. 7 is a perspective view of the left-hand portion of the table, showing the rewinding reel and its supporting shaft swung down into inactive position.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral 16 indicates a rectangular table having a guide scale 11 located in longitudinal position adjacent the center of the table. The guide scale 11 is held in raised position above the table by means of a vertical support 11a secured thereto.

In order to wind up into a roll the aligned sections of the paper tapes T after they have been spliced together, provision is made of a take-up reel 12, the shaft of which has a front handle 13 which is counter-balanced by a Weight 14 located at the opposite side of said shaft from said handle. The handle 13 has an enlarged hub 13a.

Provision is also made of a shelf 15 connected to the left end of said table by a pair of hinges 16. This shelf 15 supports a rewind reel 12a, the construction of which 2, is identical with the take-up reel 12. The shelf 15 is adapted to be held selectively in horizontal raised position by means of a latch eye 17 and a swingable hook 18. The table 15 is provided with four angular legs 19 and a bottom shelf 20.

The take-up reel 12 is provided with a pair of front and rear

circular flanges

21, 22, and also has a rear shaft 23 rigidly connected to the flange 21 by means of collars 24 and 25-, saidcollars being adapted toengage the upper portion of the rear bracket 27.

Provision is also made of a front bracket 26, similar to the rear bracket 27, both of said brackets having bases 28, 29, which are secured by means of

bolts

30, 31, and

nuts

32, 33 to the table 10.

The shaft 23' is provided with a forward extension 34 which is adapted to fit within the rear end of a hollow mandrel 35 (Fig. 3), having a slot 36 extending throughout its length, said slot being adapted to receive the end of the first paper tape T which may be threaded therein for winding all of said paper tapes successively in aroll upon the take-up reel 12.

The slot 36 is provided with an enlarged forward end 37 for detachably receiving a rectangular drive pin 38 form-ing an integral portion of a forward shaft 39 hav' ing a pair of circular grooves 40, 41, which are adapted to selectively receive a vertical plunger 42 having a rounded bottom head 43 and a top handle 44.

The plunger 42 is mounted within a vertical bearing member 45 which has a threaded reduced lower end 46 adaptedto be screwed within the front bracket 26. Provision is also made of a spring 47 which presses downwardly upon the rounded bottom head 43 of the plunger 42. The front bracket 26 also has a cylindrical recess 48 for receiving the spring 47.

The flange 22 has a collar 22:: secured to the shaft 39 by a pin 22]).

The collars 24, 25 and the handle hub 13a are secured in place by means of

pins

49, 50, 51, as clearly shown in Fig. 2.

Splicing apparatus The splicing apparatus, for attaching the short sections of pressure sensitive materal, such as Scotch tape, transversely to the movement of the aligned paper tape T, comprises a rear bracket 52 having a base 53 secured to the table 10, as by screws, and said bracket 52 is rovided with a pair of parallel upstanding side plates 54, 55 for detachably receiving a horizontal shaft 56 which holds a two-part spool 58 of Scotch tape.

Provision is also made of a knurled knob 59 on one side of the plate 54, which may be removed to permit the Scotch tape spool 58 to be taken out of the bracket 52 and replenished whenever necessary.

The knob 59 is mounted upon one end of the shaft 56, the other end of which is provided with a collar 60 secured to said shaft 36 by means of a pin 61.

At a centralized point on the table 10, provision is made of a pair of vertically spaced Scotch

tape feeding wheels

62, 63, the former being relatively large with respect to the latter.

The bottom wheel 63 is mounted upon a shaft 73 carried by an angular bracket 63:! secured as by screws, not shown, to one side of a slot 72 in alignment with the top feed wheel 62, the axis of which is directly above it. The large feed wheel 62 is mounted on a shaft 64 carried by a bracket 65 secured to the table 10 and is provided with a lateral hub 66 which engages one side of the large feed wheel 62. Provision is also made of a collar 67 secured to the shaft 64 by means of a pin 68.

The large feed wheel 62 is provided with a side knurled knob 69 having a circular reduced ection 70 within which a set screw 71 is mounted, said set screw engaging the 3 shaft 64 for holding the large wheel 62 securely upon said shaft.

Provision is also made of a cutter blade 74 adapted to move up and down within a narrow slot 75 in the table directly in front of and spaced from the slot 72.

The cutter blade 74 is carried by a rectangular plate 76 secured to a vertical haft 77 which is mounted to slide vertically within an angular bracket 78 having a base 79, secured to the front of the table as by screws 80.

The top of the shaft 77 is provided with a handle knob 81 which is pressed upwardly at all times by means of a spring 82, (Fig. 6).

The pressure plate 76 is adapted to be limited in its upward movement by means of a vertical stop pin 76a on the bracket 78.

Provision is also made at the lefthand portion of the table of a horizontal cutter member 83 for severing the tape at any point whenever desired.

The cutting member 83 has a handle 84 at one end, and a pin 85 at its other end for pivotally securing it to the table 10.

Provision is also made of a pair of heavy transverse tension rollers 86 adjacent the

reels

12 and 12a to press the tape down upon the table to prevent over-running.

The rollers 86 are carried upon U-shaped wires 87 secured to the

brackets

26, 27, by means, not shown.

While there has been disclosed in this specification, one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclo ure, but may be modified and embodied in the various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
