GUIDE FOR WEAVING COlLED-WIRE FABRIC.

SIECIFIGATION forming part of Letters Patent No. 464,693, dated December 8, 1891.

Application filed April 13, 1891. Serial No. 388|6B7. (No model) To aZZ whom, it may concern.-

Be it known that I, ABEL H. FROST, 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 the Manufacture of Coiled- Wire Fabric; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates particularly to means for guiding the coilsin machines for weaving coiled wire.

The invention has no bearing upon the coilforming mechanism. Any of the well-known forms of mechanism for this purpose may be used in connection with my improved guides, the specific purpose of the guides being only to direct the course of the coils after they leave the coil-forming mechanism and to hold the last of the finished coils in suitable position for the intertwining of the coil being proj ected from the coil-forming mechanism.

In the accompanying drawings, Figurel is a section in line a b of Fig. 2, looking toward the left, in which my improvement is applied to a pair of jaws. Fig. 2 is a plan. Fig. 3 is a detail view of a portion of said jaws. Fig. 4 is an end view of a pair of rolls embodying my improvement. Fig. 5 is a side view of a portion of said rolls. Fig. 6 is a longitudinalvertical section through said rolls.

In Fig. 1, A is the bed of the table, supporting the jawsB and C. Said jaws have their mouth directed upward and are as long as the fabric to be woven,and they maybe made separable in any suitable manner. The drawings show the jaw B bolted rigidly to the table A by bolts 13, while the jaw'C is hinged to said table. Posts A rise from the table near the jaw C, and expanding springs A located between said posts and the upper end of said jaw, press the latter normally against the jaw B. The lever C is applied to said jaw C in such manner as that it may be pressed down to draw the upper portion of said jaw away from the jaw B. These jaws are preferably made to meet face to face. When so made there is obviously no clear space between said faces for the passage of coils, but for each coil there is a spiral passage D through the material of thejaws, such passage having its axis in the joint between the two jaws and being larger in cross-section than the wires of the coil, so that there will not be any material friction in the movement of the coil through said spiral passage. When thus constructed, a half of each of said spiral passages is in each jaw, and when the jaws are separated the inner face of each shows rows of oblique cavities, as in Fig. 3; These coils are usually formed of two wires projected simultaneously and side by side; but these wires sometimes separate and diverge in the ordinary machines; but it will be seen that in these complete spiral passages the wires will not thus diverge. On the other hand, they are held together throughout the entire length of the machine. The path of the coil being formed always links through the path of the last-finished coil. This must be. the case when the coil being formed intertwines at each turn with the last-finished coil. Hence the adjacent spiral passages D are made to intertwine; but they do not communicate with each other. Each is a distinct passage by itself, and the new coil, in passing onward between the jaws, cannot take a wrong course, because every attempt to move laterally is met by the wall of the passage through which it is moving. Thus the forward end thereof can never hit the last-finished coil and divide or be deflected by the latter. The progress of the coil being formed is as definite and restricted as though the last-finished coil were not near it. Furthermore, if the pitch of the coil being formed varies a little, the coil is compelled to travel over the space measured by the spiral passage. If the pitch is slightlyincreased, so as to lengthen the coil, the walls of the spiral passage retard the forward end of the coil and make it travel over the spaces measured by the turns of the spiral passage, and if the coil is slightly shortened by decrease of pitch the walls of the spiral passage tend to extend the coil to the standard made by the spiral passage. The spiral passage holding the last-finished coil also performs an excellent function in that it holds the last-finished coil in a fixed and definite position with reference to the path to be traversed by the coil being formed. It will be seen that the movement of the coil being formed is made delinite in every respect, and that it cannot fail to properly intertwine with the last-finished coil, and that the two wires of which the coil is composed cannot diverge. \Vhen a coil has been finished, it is severed between these jaws and the coil-forming mechanism by hand-nippers or by any of the automatic cutting mechanism heretofore devised. Then the jaws are separated and the fabric raised by hand or by mechanism, so that the lastfinished coil will rest in the spiral passage next the lowest, the latter being left empty. The new coil is then projected into the lower passage and the fabric again raised.

In Fig. at a pair of rolls E are provided around their peripheries with oblique cavities, forming complete spiral passages D between the meeting port-ions of such peripheries. The cavities may be so arranged as to form two complete spiral passages between the rolls. In operation a coil is first projected into the passage farthest to the left in Fig. l. Then the rolls are turned in the direction indicated by the arrows, so that the coil is shifted toward the right and a new spiral passage is formed at the left. Then another coil is projected into the new spiral passage and made to intertwine with the first coil. Then the rolls are again turned in the direction indicated by the arrows, so that both coils are shifted to the right, and still another spiral passage is formed at the left. Then another new coil is projected through the spiral passage now at the left and made to intertwine with the latter of the two previously-made coils. Then the rolls are again shifted and more coils added in the same way.

t is deemed unnecessary to show the manner of mounting and progressing these rolls, because fluted rolls or rolls having projections upon their peripheries have been heretofore used to hold and progress coiled-wire fabrics.
