Sept. 15, 1953 w. J. FISHER STOCK GUIDE FOR ROLLING MILLS AND THE LIKE Filed May 20; 1952 William J. Fisher IN V EN TOR.

Patented Sept. 15, 1953 UNITED STATES TENT OFFICE STOCK GUIDE FOR ROLLING MILLS AND THE LIKE 2 Claims.

The present invention relates to new and useful improvements in stock guides for use in guiding strips to rolling mills and other metal working machines.

An important object of the invention is to provide a guide roller mounting pivoted adjacent each edge of the strip and in each of which a pair of fixtures for double pairs of rollers are pivoted for independent self-adjusting movement of the pairs of rollers to compensate for imperfections and possible inaccuracies in the contacted edges of the strip.

Another object of the invention is to provide easily removable pivots for the fixtures to quickly remove and replace the pairs of rollers as a unit, when necessary.

A further object of the invention is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view;

Figure 2 is a perspective view on an enlarged scale of one of the roller mountings; and,

Figure 3 is a sectional View taken on a line 3-3 of Figure 2.

Referring now to the accompanying drawings in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of my invention, the numeral 5 designates a mounting frame composed of a top 6, bottom 1 and a pair of end walls or spacers 8 rigidly fixed to each other substantially in the form of a box having an open front and an open rear.

A pair of U-shaped or channel-shaped fixtures 9 are positioned on their sides in the front of mounting 5 and are pivoted for horizontal swinging movement on pins Ill removably supported in a vertical position in the top 6 and bottom I of the mounting. Pins H] are retained in the mounting by a locking key ll fitted in a keyway l2 in the upper end portion of the pins and with the keys resting on the top 6 of the mounting. Spacing washers I3 are positioned on the pins between the top of the fixture and the top 6 of the mounting and also between the bottom of the fixture and the bottom I of the mounting.

A pair of rollers M are rotatably mounted in the open front of each of the fixtures on vertical 2 pins l5 and with the rollers protruding beyond the fixtures and mounting.

Alined openings I6 are formed in the top 6 and bottom I of the mounting to receive the upstanding pin ll of a carrier l8 on an adjusting screw l9 having oppositely threaded portions, whereby a mounting 5 may be positioned at each edge of a metal strip 20, as it is fed to a metal working machine 2| between the rollers, to adjust the mountings relative to the strip by means of screw it.

The mountings ii are free to pivot on the pins I? and the fixtures 5 for the pairs of rollers M are free to pivot on the pins ID to compensate for a possible defect or inaccuracy in the edge of the strip. By providing the mountings with independently pivoted pairs of rollers greater assurance is made possible for accurately guiding the strip centrally in the machine.

In View of the foregoing description taken in conjunction with the accompanyin drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprebended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A stock guide of the class described comprising a roller mounting having an open front, means pivotally supporting the mounting for horizontal swinging movement adjacent an edge of work traveling along the open front of the mounting, a vertical pin in the mounting, a roller fixture pivoted on the pin for horizontal swinging movement at the open front of the mounting, quick releasable locking means holding the pin in the mounting, and a pair of guide rollers journaled in the fixture and having a portion of each roller protruding beyond the open front of the mounting for contact with the Work.

2. The combination of claim 1, wherein said locking means comprises a keyway in the pin, and a key engaged in the keyway and resting on top of the mounting.

WILLIAM J. FISHER.
