Patented Oct. 15, 1935 UNITED STATES PATENT OFFICE GUIDE Application December 29, 1933, Serial No. 704,567

1 Claim.

This invention relates to guides, and more particularly to those used for guiding hot rod from the end of a mill to an adjacently disposed reel, although not limited thereto.

In the manufacture of hot rod, considerable difficulty is met in satisfactorily guiding the work-piece to a reel, largely for the reason that the velocity of its trailing end is retarded by the usual curved tubular guide. While the rod is in the rolls of the mill they force it through the curved tube to the reel, but as the trailing end leaves the rolls it has to be pulled along by the rotation of the reel. This results in the forma tion of small diameter coils, and a pigtall at the end thereof. In addition to this, certain grades of high-carbon material have to be rolled at increased temperatures, otherwise they will stick in the curved tubular guide.

One object of the present invention is the provision of a novel guide for red mills which will completely overcome the usual friction encountered, and thereby obviate the difficulties referred to.

Another object is to provide a novel device of the class described which may be cheaply and easily manufactured and installed on existing types of rod mills.

These and further objects of the invention will be apparent after referring to the drawings, in which:

Figure 1 is a plan of the apparatus of the invention as used on the exit end of a rod mill.

Figure 2 is a side elevation.

Figure 3 is an end elevation.

Figure 4 is an enlarged side elevation.

Figure 5 is a sectional View on the line V-V of Figure 4.

Figure 6 is a fragmentary sectional end elevation.

Referring more particularly to the drawings, the numeral 2 designates the exit rolls of a conventional rod mill. A rod shifter housing 3 is positioned adjacent the rolls 2, and provided with a feed-in tube t. A rod shifter B is pivoted on the upper portion of the housing 3, as at l. The housing also carries a manifold S which is pro vided with rod'outlet tubes it! and l2, which convey the rods from the shifter 6 to reeling devices, as at I3 and Hi. Each of the reels I3 and M is provided with a conventional bundle conveyer, as at 15 and [6, respectively.

According to the present invention, a curved conduit l8 of substantially rectangular crosssection is mounted between the end of the delivery tubes IE3 and I2 and their respective reels I3 and I4, and are each held in position by means 5 of a vertical support W. A plurality of bolts 20 are arranged along the upper edge of the curved conduit it in a line conforming substantially to its axis, while a similar series of bolts 2| are disposed along the lower edge of the conduit l8 in 10 curved spaced relationship.

The bolts 2i! and 2| are held against movement by means of nuts 22 on their ends, and each carries a pair of ball bearings 23 suitably maintained in spaced relationship. A plurality of rollers 24 15 are counterbored on their sides, as at 25, to receive the ball bearings 23 and thus be mounted one on each of the bolts 29 and 2i. Each of the rolls 24 is provided with a grooved periphery, as at 26. It is found, in practice, that best results 20 are obtained by locating the bolts 20 and 2| in ofiset relationship with respect to each other.

When processing high-carbon steels, it is especially important that rods are not coiled while in contact with water from the mill. In order 25 to obviate this possibility, the under sides of the curved and substantially rectangular housings l8 are each provided with a removable plate 28, which is disposed relatively adjacent its vertical support 19. The plate 28 is held in position by means of capscrews 29, which may be quickly removed when necessary.

While I have shown and described one specific embodiment of my invention, it will be understood 5 that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined in the following claim.

I claim: 40

In a guide for rod mills, a support adjacent the reel for said mill, a conduit disposed between said support and said reel, a plurality of upper and lower shafts secured to said conduit and defining a curved path between them, at least one antifriction bearing on each of said shafts, and a grooved roller mounted on each of said bearings, said upper shafts being offset with respect to vertical planes through said lower shafts.
