WIRE COVERING MACHINE.

lnylununllunnnnunu; i A Y Y Inventor: bybdufg Atty platform are rotated simultaneously in the same direction, so that as the sliver indicated at g is spirally wound about the wire d, it will be compressed to size and compacted in a manner to matte the fibers of the sliver or other material, and bring' the coveredwire to substantially tlie saine diameter throughout.

The frame a above the compacting die f supports a braiding mechanism h of the usual and well known construction, including tensioning devices h', an actuating gear train h2, and a slotted plate k3, for imparting the desired direction of travel to the various spindles supporting the spools containing th'e cords or strands from which the braid is formed. s The operation of this braiding mechanism is old and well known infthis art, and description of further details thereof is therefore not essential.

The gear train h2 haspower transmitted thereto through the gear h, the shaftl h of which has a wormz' thereon meshing with the worm wheel i', the shaft of which is connected by a suitable gear train j--j` with the feed drum e. The shaft h5 also has a hand crank i2 by means of which the m a chine may be hand operated when setting up for a run thereof.

Since the strips of sliver or other material will ordinarily be at least an inch in breadth,

it is apparent that to properly synchronize the various functions in a machine, it is essential that the platform b shall have but one rotation Vor cycle thereof during thatinterval in which the braiding mechanism shall have covered a length of wire corren spondinglwith the breadth of said sliver, and

that the functions of the l platform and the braiding mechanism sha be' so synchrolnized asto secure 4a uniform finish'v of the product.

To secure the desired result, I provide a ar connection between the gear b2 upon t e edge of the platform b andthe gear h* `transmitting power to, the braiding spinldles, the ratio of this gearin being' such as a secure the desired relative speeds of the platform and said braiding mechanism. This gearin consists of a shaft k having at one end t ereof a ar lo meshing with the gear h, and carrying a ar k" meshing with the gear b', If desir power may be aplied to the sliver winding mechanism an also to the braidin mechanism through v the `pulley k' upon sai shaft'lc.`

One or more containers c may be mounted upon the platform gb* aecordin to the number of 4plies of the sliver whic are to be applied to the w-ire d. g Ordinarily at least two such plies would beapplied.

The operation of the'- herein described device ssubstantially as follows .I

When startingv a machine, the end of the wire d W 111 be secured to arope or cord the invention.

which will be fed through the opening b of the platform b, through the compacting die f', and about the feed drum e. In starting the machine, the sliver wind- .ing mechanism and the braiding mechanism may be actuated through thehand crank 2 until a suiiicient length of wire has been covered with sliver and had the braid applied thereto, to 'ensure proper 'conditions during a continuous run of the machine. This actuation of the shaft i by the hand crank i2 will ensure the actuation of both the braiding mechanism and the sliver winding mechanism at the proper relative speeds, through the gears h* and b and the gears icl-k2 upon the shaft k.

Vhen this condition has been established,`

power is applied to said shaft lc and thereafter the machine will run automatically,

drum e, which speed will be determined and controlled by thecapacity of the braiding mechanism. As the wire with the sliver thereon passes through the die f', it will be tightly wound thereon and compacted so as to matte the fibers of the sliver, and when two or more plies of sliver are used, secure a proper bond between the succeeding plies, vwhich should be' so set with relation to the wire that .the abutting or lapping edges of one ply will lap those of the other, thus securing continuity in the matted body thus applied to the wire.

After leaving the die fi 'there will be a slight tendency of the compacted sliver to expand and the outer fibers thereof to spring outwardly, so that these fibers will be caught in the meshes of the braid and entangled or roo enmeshed therein so as to ensure a firm bond application of the asphaltum 'or othericom:

position to the covered wire, and durin the final finishing operations of sizing and ironiio ing, portions of said sliver will be forced -4 over the ed es of the braid and thus more firmly4 bon thebraid to the body of the covering.-

It is not my intention limitjthe inven.
