'UNITED PATENT OFFIC.

JOHN E. EARLE, OF BROOKLYN, NEWv YORK, ASSIGNOR TO HIMSELF AND SAM. HATHAWAY.

MACHINE FOR MAKING TAPE TRIlVIlVIING.

Specification of Letters Patent No. 32,663, dated .Tune 25, 1861.

f7o all whom 'it may concern:

.Be it known that I, JOHN E. EARLE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Machine for Making Trimming from Tape or other Ribbon, and commonly called Tape Trimming; 2 and I do hereby declare that the following' is a full, clear, and exact description of the construction and operation thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view. Fig. 2 is a sectional view. Figs. 3, 4L, 5, 6, 7, show the manner of laying the five folds required in making the particular kind of trimming for which this machine is adapted. Figs. 8, and 9, represent detached parts of the machine.

Same letters and characters refer to like parts.

The nature of my invention consists, first, in folding the tape or other ribbon by means of pincers or folders formed of 'plates or wires or both or their equivalents, so arranged as at the right moment to move in to, (the tape being in or near the center around which the folders are placed,) and clasp the tape, and by a whole or partial revolution of the folders to fold the tape to the required form or angle, then withdrawing, when a second pair of folders in like manner as the first enters and lays the second fold and withdraws, and the successive folders continuing so to do until all the required fo-lds are laid and the web of the tape brought back to place of beginning; secondly, in a device for untwisting the tape (twist being caused by laying two folds in one direction and three folds in opposite direction making a twist in the tape of one half round,) by means of a continuous revolution given to the holder upon which the tape (from which the trimming is to be made) is placed turning it in the' direction to accomplish the result required; thirdly, in a device for carrying the tape from the last folders into the position required to receive the first folders, and retaining the tape in said position until the first folders or pncers have entered and taken hold of the tape,

having its bearing in the bracket Y Fig. 2; I the spool; L the tape or other ribbon; M spur gear through which a revolving motion is given to the holder H by means of the gear R on the edge of the `disk S through the pinion N and O on the shaft P.

Operation: In Figs. 3, 4, 5, 6, 7 the folders are shown in black when at rest, red when they are in position to fold, and blue when they have folded. The tape is shown in black before the fold is made, and yellow after the fold is made. When the machine is in motion the folder D, Fig. 8, by means of the action of the cam P acting through the rod O and lever M is moved into the position denoted by the red lines, the wire 1 passing above and the plate 2 below the tape L, (the holder C still retaining the tape in position 3); when arrived at this position the folder revolves by the action of the cam B through the agency of the rod A and levers WV and U, at the same time the holder C through its connection H2 and I2, Fig. 9, with the said lever IV( operating the folder D is raised from its position A3 to B3 and allows the tape to clear from its point the folder D turning until it attains the posit-ion denoted by the blue lines and carrying the tape from position 3 to the position 4L shown by the yellow lines. During this operation the second pair of folders E enters in the same manner as the first pair D and when at or about the position denoted by the dotted lines in Fig. 3 the first pair D withdraws and returns to the position of rest denoted by the black lines, and the second pair of folders continues to enter until the position denoted by the red lines Fig. l is reached, the plate 1 being above and the plate 2 below the tape (this folder is composed of two plates so that they may hold the fold already made by the first operation) and in the same manner as the first turn to the position denoted by blue lines, carrying the tape from position 4- (in black lines) to position 5 in yellow lines, the folder E remaining in this position until the third folder F enters to the position denoted by the red lines (the wire 1 being above and the plate 2 being below the tape) when the second folder E withdraws to first position shown in black lines Fig. 3. The third folders F turning in like manner as the first and second before described to the position denoted by the blue lines Fig. 5, carrying the tape from position 5 (in black lines) to position 6 (in yellow lines) the folders F remain in this position until'the fourth folders G enter to the position denoted by the red lines Fig. 5, when the third folder F withdraws to first position denoted by black lines Fig. 4. The fourth folder G turning in the manner of the first folder before described to the position denoted by the blue lines, Fig. 6 carries the tape from position G in black lines to position 7 in yellow lines. As in this position the fifth folder H cannot enter, the pressers E and F (being in position denoted by red lines Fig. 2) are by the action of cam S closed upon the tape and folders G and holding fast the tape, the folders G withdraw to first position denoted by black lines, then the fifth and last folders H enter to the position denoted by red lines Fig. 7 (the wire l being below and the plate 2 above the tape) and turns in like manner as the first before described, down and under to the position denoted by blue lines carrying the tape from position 7 to position 8 being the position first denoted at 3 in Fig. 3. The carrier D on the spindle I of folder H carries the tape down and around to the holder C then withdrawing leaves the tape in the first described position so as to receive the first folder D commencing another operation.

As in folding the tape there are three folds in one direction and two in the reverse, there is a consequent twisting of the tape, one half around when the five folds are completed, and the tape would so continue to twist at each full operation. To overcome this continuous twisting the spool holder H is made to revolve one half around (in the direction to obtain the required untwisting) during each full operation by means of the gears M and R and the pinions N and O thus leaving the tape untwisted at the close of each full operation.

As the trimming X is formed in the nianner before described, it is carried through the trough or guide G to the sewing 1nachine or other known device for fastening the folds so as to retain them in place for use.

Power may be applied to the driving shaft R.

I do not confine myself to this one particular description of trimming herein described as the several folders may be adjusted so as to fold in various forms. Neither do I confine myself to the precise construction herein described, reserving to myself the right to modify, so long as I do not depart from the general principles herein set forth.

Having thus fully described my invention what I claim therein as new, and useful, and desire to secure by Letters Patent is,

l. The folders D, E, F, G, and H, or their equivalents constructed and operating in the manner and for the purpose substantially as specified.

2.
