TAPlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 794,553, dated July 11, 1905.

Application filed April 30, 1902. Serial No. 105,274.

To all whom it may concern.-

Be it known that I, FRANK A. SANDsTRoM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Taping-Machines, of which the following is a specification.

My invention relates to improvements in machines for winding tape on wires or Wire coils; and the objects of my improvements are to produce a machine of this character which may be economically constructed, simple in operation, not liable to get out of order, and in which the wire may be easily handled with special reference to turning the sharp bends found in some coils for certain purposes.

My invention consists generally of a frame on which the operative parts are supported and which is adapted to be secured to a table, of a reel rotatably mounted in the frame and adapted to have the tape wound thereon and unwound therefrom, means for driving said reel, a device for regulating the tension of the tape when the machine is in operation, and a guide through which the tape is fed to the reel, all of which will be fully described in detail hereinafter.

In the accompanying drawings, which form a part of this application, Figure 1 is a side elevation of my improved machine. Fig. 2 is a view partly in side elevation and partly in longitudinal section. Fig. 3 is a top plan view with the tension devices omitted. Fig. 4 is a transverse section through the reel and its case or frame. Fig. 5 is a front elevation or View looking in the direction in which the tape is fed to the machine, and Fig. 6 is a side elevation from the side opposite to that from which Figs. 1 and 2 are taken and from which the tension devices are omitted.

Referring to said drawings in detail, A A represent two legs or standards which support the frame of the machine and have bolt or screw holes therethrough, whereby they may be fastened to a bench or table.

B B represent two complementary castings which form the frame of the machine and support the operative parts and also serve as a casing for the reel G, which is mounted in the cylindrical portion of said castings. The rear portions of the castings are secured firmly together in any suitable manner, and at their front end is a gap or opening 7), which serves as an entrance to the reel for the tape. The casting B is formed with bosses b and 6 which are drilled through, and in the openings pins 6 b are mounted. On the pin 5* a cogged drive-wheel D is mounted, which may be driven by any suitable motive power or operated by hand on the handle CZ. The teeth of the drive-wheel engage with corresponding teeth on the pinions e 6 which are respectively mounted on the pins 5 The forward or cylindrical portion of the castingB is formed on its periphery with overhanging flanges I), which serve as guides and side bearings for the reel. The casting B at its forward portion is formed with flanges 6 which extend toward the center of the cylindrical chamber, guide and form bearings for the reel, and leave a rectangular opening 5 into said chamber. To the upper side of the parts B B, near the opening 6', are secured pins ff, on which is slidably mounted a plate E. Said plate has a downwardly projecting and outwardlycurved extension f and has collars f formed thereon, which surround said pins. The pins are threaded and provided with wing-nuts f between which and the collars f spiral springs f are mounted on the pins and exert their tension normally on the collars, thereby pressing downwardly said plate.

Placed loosely in the cylindrical chamber, at the forward portion of the castings B B, is a reel G, which is preferably formed of a skeletonized cylindrical casting having a break or opening at one point, as at g, and extending between the two side walls of said casting and having bearings therein are rollers 9 which are adapted to rotate and to have the tape pass thereover circumferentially before it is wound about the wire or coil. Secured to one of the side walls of the reel by screws 9 is a cogged collar or annular rack g the teeth of which mesh with the teeth of the pinions e 6 whereby the reel is rotated.

At the lower side of the opening 6 in the casing there is secured to the latter a tapeguide H, which is formed of two wires bent to overlap each other in a horizontal plane and with their free ends bent upwardly, thus leaving a narrow opening between the wires through which the tape passes as it is fed into the machine or reel. The size and shape of the opening are such that the tape cannot pass therethrough unless perfectly flat, and the overlapping ends of the wires facilitate the insertion of the tape in the guide when the operation is started, inasmuch as the tape does not have to be threaded into the opening, but can be drawn in at the'side.

In the operation of my improved machine the end of the tape is inserted through the guide H and carried through the opening I) in the casing and the opening g in the reel and is passed once or twice around the rollers g and the end is then given one or two turns about the wire to be covered. The drivewheel D is driven in the direction indicated by arrow in Fig. 1, which serves to rotate the reel in the same direction, thus carrying the tape J around the outside of the reel or between the rollers and the inner cylindrical walls of the casing. As the tape is wound upon the reel it is also unwound therefrom and wound upon the wire K, and as the diameter of the latter is less than the diameter of the reel it is apparent that the tape will windon the reel faster than it will wind on the wire, so there will be several coils of tape around the reel; but the amount will be limited by the operator to the capacity of the machine. The tension device E being adjusted initially for one or two coils on the reel will automatically yield through the compression of the tension-springs f to the thickness of several coils of the tape on the reel, and, if desired, the tension can be adjusted by the wing-nuts. The tape may be first cut in the desired lengths before being attached to my machine, or it may be unwound directly on my machine from a spool, the latter being suitably supported in front of my machine,

and when the reel has the desired length of tape wound thereon the tape is severed near its spool.

It is apparent that various modifications may be made in the details of construction of my machine without altering its general construction 'or mechanical principles, and for this reason I do not wish to be limited in my patent to the precise construction and arrangement shown, but

What I claim, and desire to secure by Letters Patent, is-

1. A machine for winding tape on wires, composed of a cylindrical casing, a tape-winding reel rotatably mounted in said casing and adapted to receive the tape thereon and to have the tape unwound therefrom, means for driving said reel and a tension device attached to said casing.

2. In a machine for winding tape on wires or the like, a cylindrical casing, a reel rotatably mounted in said casing and adapted to have the tape wound thereon, rollers forming a part of said reel and directly supporting the tape, means for rotating said reel, and a tapeguide secured to said casing.

3. In a machine for' winding tape on wires composed of a casing and a reel rotatably mounted in said casing and adapted to have the tape wound thereon, an adjustable tension device secured to said casing and adapted to regulate the tension of the tape on the reel, substantially as set forth.

4. A machine for winding tape on wires, composed of a casing having openings therein to receive the wire and the tape, a reel rotatably mounted in the casing and having openings therein to receive the wireand the tape, means for driving said reel, means for guiding the tape to said openings in the easing and reel, and means for regulating the tension of the tape on the reel, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
