Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed May 16, 1914. Serial No. 839,046.

To all whom it may concern Be it known that 1, CLAIR L. VAN N'nss, a citizen of the United States, and residing at Akron, in the county of Summit and State ofOhio, have invented certain new and useful lmproven'icnts in Insulating-Heads, of which the following is a specification.

I This invention. relates to certain new and useful improvements in insulating heads, and is an. in'iprovement upon the type of ill-- in my Patent #1,l00,002, June 16, 191 the present invention, like the one just referred to, being preferably, though not necessarily, of the multiple form/ The presentinvention has for its main object to provide means in' an insulating head, for adjusting the wire guider or guiders so as to compensate for the side pressure within the insulating chamber against the wire being insulated, and thereby absolutely having a detachable point or nipple, where-- by different sized nipples may be used with the same guidcr-spindle, obviating the ne- 5 cessity of changing guiders for different sized wires, and effecting a considerable saving in cost. 1

Other objects of the invention will appear as the same is hereinafter more fully described and claimed, and in describing the' invention in detail, reference will be had .to the accompanying drawings illustrating preferable embodiments of my invention, it being understood that although herein illustrated as a multiple formol insulating head,

I do not limit or confine myself to such construction or arrangement, as the forms of guider and die shown may be used singly in an insulating head.

In the drawings: Figure 1, is a longitudinal sectional view of an insulating head showing a preferred form of guidcr anddic construction, the relief valve of the insulating' head being partly broken away, Fig. 2, 5b is a view of the same form oi insulating head, the view being partly in elevation,

sulating head shown, described, and claimed partly broken away, and partly in longitudinal section, Fig. 3, 'is a horizontal fragmentary view of part-oi an insulating head, illustrating a modified form of wire guider 6g and mounting therefor, Fig. 4, is a similar view showing the die which is used with the lorm ol' guider shown in Fig. 3, and Fig. 5, is an end view of the guider shown in Fig. 3, the insulating head being broken away. 5

Insulating heads of the type here "shown are known generally as side delivery type, that is, a type in whichthe material with which the wire is coated is fed to the side of the wire instead of in line with the wire, the latter type of devices being gener-v ally known as straight delivery devices. The insulating head lere shown, like in my patent referred to, isadapted to be attached to a suitable compressor from which the material is fed into the insulating head. As the construction of the insulating head per se, and the relief valve therefor are fully shown and described in my patent, they will be referred to and described only generally herein,

i The insulating head, like in my patent, is shown as consisting of a main member 10,

' and. a cap-plate 11,the two members forming an insulating chamber 12, for which a relief valve 14, (fully shown. and described in my prior application) is provided.

As stated,'thc present invention relates particularly to the wire guider, and the manner in which the same may be adjusted.

As shown in Figs. 1 and .3, the construction embodies a mounting in which both the wire guider and the die are received, such mounting comprising a gu'ider-sleeve 15, and a dieslceve 16, mounted respectively in the main member 10, and cap plate 11, and connected together by tie-bars 17, spacedequidislant, and having their inner edges rounded off so as not to interfere with the passage of the plastic material onto the wire.

p The guider-slecve is provided at its inner end with a seat 18 and at its outer end has a head 19 which abuts against the outer face of the main member 10, and has a rounded or convex outer face forming an external seat 20. This guider-sleeve 15 has its bore 21 tapering, being widest at the outer end oi" the sleeve, and through this tapering bore is received the hollow-spindle 22 of the wireguider. The said spindle of the guider is formed at its inner end with a head 23 rounded for seating engagement with the seat 18 and having 'a threaded socket for the reception of the threaded shank 24 of the guider-point or nipple The head and nipple 25 are each preferably provided with fiat surfaces 26, or their equivalent, in

order to enable implement.

Outside the guider-sleeve 15, the guiderspindle carries a pillow-block 27, which has a concave inner face 28 that seats upon the convex outer face 20 of the sleeve head 19,

gripping by a wrench or like being held in any position thereon to which it may have been adjusted by lock-nuts 29.

The mounting or connector for the guider and the die is locked at the other end by a. lock-nut 30, threaded onto the outer end of the die-sleeve 16, said sleeve being also interiorly threaded to receive the die 31.

In the construction shown in Figs. 3, 4t,"

same reference numerals have been used on all those parts which are identical with the construction of Figs. 1 and 2.

3 The die 31 in this construction is mounted in a die-sleeve 16' threaded into the capplate 11, and for This pur ose provided at its outer end with a head 1 In order that the sleeves 1-5 and 16' may be threaded into the members 10 and 11 respectively, the peripheries thereof will be fiat-faced as shown for the head 28 of the-sleeve 15,

that they may be readily gripped by a wrench. j I j I In Figs. 1 and 2, the three upper guiders are shown in difierent adjusted positions, the one at the left being shown with the guider ,point or nipple perfectly alined with the die, the one inthe center shown slightly adjusted so as to'somewhat off-set the nipple point with respect tothe die, and the one at the right hand side of the figure shown adjustedto the full limit permitted.

The adjustment of the guider is efi'ected by a slackening of the nuts 29 and then delivering a side blow mpon theplllow block 27. The guider it is-to. be observed 15 clamped between two curved seats that have a spherical movement on a. common-center. Whena blow is delivered on-the plllow-block -27, it reverses the nipple point, 'slnce the seat center is within the limits of the length of. the guider member.

By this simple and effective adjustment it will be noted that I am enabled to readily and quickly adjust the wire guider nipple with respect to the die, so as to compensate for the side pressure within the chamber 12 against the wire being insulated, as with a rigidly held guider, it has been found that the pressure of material against the wire will throw it out on a curve through the die,.

- causing eccentric insulating of the wire,

which 1s, by thls construction, wholly eliminated, simply by moving the guider point or nipple over at an opposing angle to the'side pressure delivered.

In practice, any one or more of the openings may be blanked as shown in my prior application, or a filler block may be inserted in the chamber 12 as shown by dotted line 32, Fig. 1, the inactive guiders being of course removed.

What I claim is:

1. An insulating head comprising a wire die and a wire guider, the opposed terminals of which are disposed in parallelism,

the two members in fixed relation to each other whereby to displace both ends of the first member.

3. An insulating head comprising a wire die, and a wire guider bodily and swingingly adjustable relative to the die whereby to displace both ends of the guider.
