Slriha, M614 Ave. E, Chicago 17, 1121., and Elijah R. Wagner, 9718 S. Peoria St., Chicago 43, ill. Filed Aug. 29, 1963, Ser. No. 305,253 3 Claims. (Cl. 226-189) The present invention relates generally to rolling-mill equipment and, more particularly, to adjustable rollingmill guides especially suitable for conducting workpieces along a rolling-mill conveyor table to a roll pass of a rolling-mill stand.

in the process of rolling structural steel sections, the sections are rolled through a plurality of roll passes. The sections are positioned for entry into each roll pass by guides made up of a pair of spaced side-guards located on the conveyor table leading to the desired roll pass. Considerable adjustment and manipulation of the side-guards is necessary to arrange the guide, especially in a reversing type rolling mill, for properly conducting the section to various roll passes in a multi-pass roll stand. Prior to our invention, the side-guards were usually aflixed to the conveyor table apron plates by means of T-head bolts which were secured by means for locking wedges in the manner shown by Patent No. 1,110,463. This arrangement was not altogether satisfactory since the side-guards tilted when the bolts were loosened. Further, when a force was applied to the side-guards as with a sledge to move them to a new or proper position, they frequently tilted, causing the bolts to bind and become diflicult to readjust. Also, when the side-guards were subjected to heavy impacts by the sections striking against them, the T-head bolts would allow the side-guards to drift so that frequent readjustment was necessary.

It is, accordingly, an object of our invention to overcome the aforementioned disadvantages by providing an improved rolling-mill guide which includes side-guards in the form of studded bars which can be easily and positively secured in stable position.

It is another object of our invention to provide an improved rolling-mill guide which includes side-guards supported on stools which are removably secured by locking pins to platens in the conveyor table.

It is a further object of our invention to provide an improved rolling-mill guide as set forth by the preceding object wherein the stools can be easily and quickly adjusted to a relatively large number of positions along the lengths of the platens to properly position the side-guards relative to each other and the roll pass of the mill stand to which material to be rolled is to be conducted.

It is still another object of our invention to provide an improved rolling-mill guide including side-guards and stools as set forth above wherein each of the stools is provided with a bottom flange on each side having spaced holes therethrough, and the platens are each provided with staggered rows of perforations with which the holes in the stool flanges are adapted to register randomly so that the stools can be secured in adjusted positions along the platens by means of locking pins removably inserted through the registered holes and perforations.

It is yet another object of our invention to provide an improved rolling-mill guide including side-guards and stools as set forth above wherein each of'the side-gumds is provided with pairs of spaced, depending studs, one of which fits into a rotatably adjustable eccentric bushing in one of the stools on one of the platens and the other fits into a slotted hole in one of the stools on the other platen so that the angular position of one side-guardrelative to another can be adjusted by rotatable adjustment of the eccentric bushings in the stools.

It is still a further object of our invention to provide an improved rolling-mill guide which can be easily and quickly positioned without using wrenches or similar tools.

These and other objects will become more apparent after referring to the following specification and attached drawings, in which:

FIGURE 1 is a plan view of a rolling-mill conveyor table having the guide of our invention installed thereon;

FIGURE 2 is a longitudinal sectional view taken along the line 11-11 of FIGURE 1;

FIGURE 3 is an enlarged partial plan view showing a stool of the guide of the invention with parts removed for clarity;

FIGURE 4 is an enlarged partial elevational view partly in section of the stool shown in FIGURE 3 but with the bar of the guide in position;

FIGURE 5 is a view similar to FIGURE 3 showing another stool of the invention; and

FIGURE 6 is a view similar to FlGURE 4 but showing the stool of FIGURE 5 with the bar of the guide in position.

Referring more particularly to the drawings, reference numeral 2 designates a horizontally-disposed roller conveyor table of a structural steel rolling-mill utilized for conducting structural workpiece sections to a rolling-mill pass. The table 2 is provided with the usual driven rollers 6 arranged in spaced, parallel relation. The guide of the invention, which is designated generally by reference numeral 8, includes a pair of perforated platens or apron plates it} and 12 arranged in spaced, parallel relation in the conveyor table 2 extending transversely thereof with each platen being disposed between a pair of rollers 6. The perforations la in each platen are arranged in stag gered rows, as best shown in FIGURE 1, for a purpose which will become apparent.

A pair of spaced stools l6 and This removally mounted on the platens 1d and 12, respectively, by means of lockingpins 25} which are removably inserted through one of a plurality of holes or perforations 22 in a bottom flange 24 on opposite sides of each of the stools l6 and 18 and one of the perforations 14 in the platens,

The staggered rows of perforations 14 in the platens 1d and 12 and the holes 22 in the bottom flanges of the stools provide relatively small intervals of adjustment for the stools along the lengths of each of the platens. ln other words, by providing three staggered rows of perforations in the platens and three holes in the bottom flanges of each stool, each of the stools can be moved to a relatively large number of positions along the length of its respective platen and be secured therein by means of two locking pins, one inserted through each flange of the stool through a hole 22 in registry with a perforation 14 in the platen.

An overhanging guide plate 25 may be provided adjacent the bottom of one end of each of the

stools

16 and 18 to hang over and engage one edge of each or" the platens so as to guide the stools along the platens when they are adjusted therealong.

The stools 16 on the platen ltl are each provided with a vertical hole as therethrough having a countersunk portion 28 in the bottom end thereof. A bushing 39 having an off-center or eccentric hole 32 therethrough is rotat ably fitted in each of the holes 26;. Each of the bushings Ed is provided with a circumferential flange 34 at its up per end which enlarges the upper end of the bushing to an outside diameter greater than the diameter of the hole 26 into which the bushing is fitted so that the upper end of the bushing projects upwardly of the hole 26. A plurality of radially-extending knobs 36 are circumferentially spaced about each of the flanges 34 whereby the bushings can be manually grasped and rotatably adjusted in the holes 26 of the stools 16, for a purpose which will become apparent.

Each of the stools 18 is provided with an elliptical or transversely-elongated hole 37 extending vertically therethrough and having a countersunk portion 39 in the bottom end thereof.

A pair of spaced bars 38 extends substantially transversely across the platens 1t and 12 with each of the bars being supported by a stool 16 on platen 1t and a stool 18 on platen 12. Each of the bars is provided with a pair of spaced, parallel studs 40 depending from the underside thereof. One of the studs 46? on each bar fits snugly into the bushing 30 of the stool 16 supporting the bar adjacent one end and the other stud fits slidably in the elliptical hole 37 of the stool 18 supporting the bar adjacent its opposite end.

Each of the studs 49 is provided with a threaded, undercut portion 42 on its bottom end which projects into the

countersunk portions

28 and 39 of the

stool holes

26 and 37, respectively. The bars are prevented from lifting vertically out of the supporting stools by means of washers 44 and nuts 4'6 which are affixed to the undercut portions 42 of the studs.

Normally, the bars are disposed convergently at the ends thereof leading to the desired roll pass of the roll stand, as best shown in FIGURE 1. The desired position of the bars 38 relative to each other is attained by adjustably positioning the

stools

16 and 18 on their respective platens 1t) and 12 after the bars have been secured platen, the stool need only be moved slightly to achieve the desired registry of holes and perforations. The multiplicity of perforations 14 in each platen and their staggered arrangement make it possible to bring about registration of one of the holes 22 with one of the perforations 14 without moving the stool a great amount.

When the

stools

16 and 18 have been thus properly adjusted so that the bars are arranged in the desired position, a locking pin 20 in inserted in the' registered hole 22 and perforation 14 on each side of each of the stools. After the stools have been thus secured in adjusted position, the knobs 36 on each of the bushings 39 may be grasped and the bushings 3t) rotatably adjusted to bring about any fine adjustment in the angular relationship between the bars 38, if necessary.

While one embodiment of our invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
