Application filed November 18, 1914:. Serial No. 872,786.

To all whom it may concern:

Be it known that I, ALFRED BROWN, a subject of the King of Great Britain and Ireland, and resident of Denton, near Manchester, England, have invented certain new and useful Improvements in or Relating to Machines for Making Hat-Brim Wires and the like, of which the following is a specification.

This invention refers to machines for making the wires used with the brims of felt and silk hats for the purpose of preserving the correct shape of the brimsa At present, there are no means, other than the eye, whereby the operator may determine the correct position in which to fix the wire relatively to the brim. In these circumstances the wire is often wrongly fixed in the brim and as a result the brim quickly loses its correct shape and the hat has to be treated as a job hat and sold at a reduced price.

This invention has for its object a machine which will mark the wire at one, or two points and, preferably,' at the two points which should come opposite the usual mold marks in the hat, so that by the aid of the markings on the wire and those in the hat the operator may be able to unerringly fix the wire in its correct position.

In carrying out the invention, the marking of the wire is preferably effected simultaneously with the forming of the wire into the usual oval and arched shape, that is to say, in the wire-shaping machine are two small emery wheels, which engage the wire and either lie in a plane parallel with the wire, or in a plane at right angles thereto. When in the same plane as the wire they rotate at a speed equal to that of the wire as it is drawn through the machine by the usual devices. Said emery wheels are continuously rotated, so that on the wire pausing in the usual way while the wire is being cut off after each shaping operation, the said wheels remove a portion of the-metal or the usual blue coloring and thus leave what may be termed a mark in the length of the wire.

When the wheels lie in a plane at right angles to the wire one or both of them will be held normally clear of the wire and only touch the wire each time it is stopped-for cutting off purposes. The marking of the wire may occur at one point only or at two points in the length of the wire and in the case of two points such points when the wire is shaped to the required oval will lie diabrim.

Upon the accompanying drawings,

Figure 1 illustrates a plan of the improved apparatus by which a brim wire is marked, the apparatus being arranged alongside the usual brim wire shaping machine.

Fig. 2 illustrates a cross sectional elevation of Fig. 1 (in part) on line 06-00.

Fig. 3 illustrates a plan of the brim wire.

In practice it is found preferable to arrange the marking wheels a, 0; at right angles to the wire as shown and to hold the wheel a away from the wire while the wire is "being shaped into the usual oval form, and allow it to act upon the wire only when the cutting off operation is taking place. The wheels are carried upon spindles running through blocks 6, o and receive rotary motion through bevel wheels 0, c, 0, 0. The block b is mounted upon a slide and the bevel wheels 0 0 are adapted to slide with the block, the bevel wheel 0 being held in mesh with the wheel 0 by a plate d, and the wheel 0 being free to slide on the shaft 6 while keyed to it.

The marking wheel a: is normally held clear of the wire by means of an eye bolt f, a chain 9, a lever h, and a cam z of the wireforming machine, such cam only allowing the wheel a under the force of a spring j acting between the stop 76 and block b to touch the wire once in each revolution which corresponds with the traverse of the wire for making a complete brim wire, the feed of the wire being stopped as usual while the wire is cut off and such stoppage being made use of to allow the wheels a, a to mark the w1re.

With the machine altered to make brim wires of larger or smaller size the speed of the cam automatically determines the correct marking of the wire.

The Wheels a, a may be of emery (or emery covered), or they may be steel disks, it being sufiicient to remove the usual blue coloring from the wire to afford the desired mark see Fig. 3.

Instead of the mark, or marks being formed by removing a portion of the surface of the wire, the mark, or marks may be formed by portions of the wire being pinched or reduced in diameter or otherwise altered in shape, or the markings maybe produced by burnishing.

What I claim is V In a machine for making hat-brim wires and the like, in combination, two rotary eutter disks, a spindle for each disk, a bearing block for each spindle, a stationary base plate upon which one of said blocks is relatively fixed and the other of said blocks is slidably mounted at a slight distance apart and between which a wire to be marked passes, shaft bearings on the said plate, and

1 a shaft supported in such bearings at right angles to the disk-carrying spindles, a bevel wheel on each disk-carrying spindle, further bevel wheels, one of which is fast on and rotates with the said shaft and meshes with the bevel wheel on the disk-carrying spindle of the fixed block, and the other of which bevel wheels is slidably keyed upon the said shaft and meshes with the bevel wheel on the disk-carrying spindle of the sliding block, a forked plate on the sliding block engaging the slidable bevel wheel, a spring for moving the sliding block toward the fixed block, and means for moving and holding the sliding block away from the fixed block and periodically releasing the sliding block, and a spring for moving the slidable block when released toward the fixed block to allow the disks to approach and mark the wires, as set forth.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

ALFRED BROWN.
