' This invention concerns a binding tape feeding cage adapted for use in association with a sewing machine or the like.

According to the invention there is provided a bracket having perpendicularly disposed arms for engaging on a suitable support such as a sewing machine table. A reel is adjustably mountable on one end of one of the bracket arms. A spacer plate is adjustably mounted in the reel. A roll of tape can be inserted in the reel which is provided with a plurality of rollers at the periphery thereof for supporting the roll of tape. The adjustable plate permits the available space for the tape in the reel to be adjusted to accommodate tape rolls of various thicknesses.

. It is therefore a principal object of the invention to provide a cylindrical cage or feeding a roll of binding tape, the reel being provided with a" plurality'of peripherally disposed rollers and an axially movable spacer plate.

A further object is to provide a cage or reel of the character described with a mounting bracket for adjustably supporting the reel with respect to a support.

' Another object is to provide a reel of this kind with a device to take the strain otf of the tape.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of invention.

FIG. 2 is an end view of the device.

FIG. 3 is a sectional view taken FIG. 2.

FIG. 4 is a side view of the device, on an enlarged scale, showing a supported roll of tape in dot-dash lines.

FIG. 5 is a sectional view taken on line 5-5 of FIG. 4.

FIG. 6 is a perspective view of the spacer plate.

In FIGS. 1-5, there is shown a binding tape feeding cage 10 made in accordance a device embodying the on line 3-3 of with the invention, including an L-shaped bracket 12 having arms 14 and 16. Arm 14 is bent at right angles to arm 16 and has spaced holes 18 for receiving screws by means of which the device can be mounted on a table such as a sewing machine table in a convenient position for use. Arm 16 has a hole 19 at its lower free end for receiving a threaded stud 20 of reduced diameter at the end of a rod 22. Nut 23 is screwed on the stud. The rod may be inserted telescopically in a tubular sleeve 24 secured axially to a circular plate 26 of reel 30. Brace bars 28 spaced circumferentially around the sleeve reinforce its attachment to the plate 26. A thumb setscrew 32 in sleeve 24 permits the rod 22 to be secured in a desired position with respect to plate 26. A plurality of pins 34 are secured in circumferentially spaced array around one half of the cage and rigidly space plate 26 from circular plate 27. Mounted on the pins are tubular rollers 36 which freely rotate on the pins. A tubular nipple 38 is secured to plate 27 and extends axially therefrom outwardly in axial alignment with sleeve 24.

A circular spacer plate or disk 40, as best shown in circular plate 26 of the reel for supporting and "ice FIG. 6, has an axial shaft 42 which passes through hole 43 in plate 27 and is slidably disposed in the nipple 38. A thumb setscrew 45 inserted in the nipple adjustably secures the plate 40 in a desired spacing between the

plates

26 and 27.

A roll R of tape T, as shown in dotted lines in FIGS. 4 and 5, can be inserted loosely in the reel and supported on the rollers 36. As the tape T is drawn up while in use such as in sewing to a garment, the roll turns freely on the rollers. The roll is confined between opposing

parallel plates

26 and 40 whose spacing is slightly greater than the axial thickness of the roll R. A particular advantage of this arrangement is that the roll floats freely and is not confined at its center as in conventional roll and spool holders. Thus the tape can be withdrawn from the roll as fast as required without danger of straining or stretching the material of the tape.

In order to take the strain off of the tape during the binding operation, I have provided an additional pin 50 disposed tangentially of the reel by means of a bracket arm 52 which is secured to the outer surface of the reel by means of adjacent pins 34 extending through holes in the arm 52. A tubular roller 54 is sleeved around the pin 50 and is secured thereon by a screw 56. One end of the pin is secured to the bracket by a nut 58 and its other end is free and is spaced slightly outwardly of the peripheral edge of the circular plate 27, as best shown in FIG. 5. In use, the free end of the tape T on the roll R is slipped over the roller 54 on pin 50 and guided upwardly to the sewing machine. The moving roller 54 takes the strain 01f of the tape during this tape binding operation.

The device is fabricated of inexpensive metal parts which can be assembled and secured by welding in conventional metal working machinery at low cost. The device is rugged in construction, long lasting and troublefree in use.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

l. A binding tape feeding device, comprising a pair of flat plates, a plurality of pins rigidly secured between the peripheries of the plates for substantially halfway around and holding the plates in fixed, spaced, parallel disposition, freely rotatable tubular rollers respectively sleeved on the pins between the plates, a spacer plate adjustably disposed between said pair of plates, means for adjusting and retaining the spacer plate in a selected position between said plates and parallel thereto, said means comprising a rod extending axially from said spacer plate, a tubular nipple secured to the one of said plates and extending axially therefrom, said rod being slidably received in said nipple, and screw means for holding the rod in a selected position in said nipple whereby the spacer plate is held in selected spacing from the other of said plates, said pair of plates being circular, a sleeve extending axially from the other of said plates, a bracket having a shaft telescopically received in said sleeve and screw means for fixing the shaft in position in said sleeve, said bracket having perpendicularly disposed arms for supporting the device upon a support, said shaft being secured to one of said arms, and brace bars secured between the sleeve and said other plate holding said sleeve in axial extension from said other plate.
