ATTORNEX Patented Feb. 5, 1935 UNITED STATES FEED MECHANISM FOR GATHERING TABLES AND THE LIKE Clarence L. Taylor, Youngstown, Ohio, assignor to The Aetna-Standard Engineering Company, Youngstown, Ohio, a corporation of Ohio Application March 23, 1932, Serial No. 690,732 reclaims. (01. 193-29) This invention relates to feed mechanism for gathering tables and the like.

Mechanism of this type is commonly employed to feed bars which are being cut from a billet in rapid succession, as by means of flying shears,

to a gathering table, on which the bars are permitted to accumulate and cool, and from which .theyare periodically removed.

A gathering table, such as is commonly employed for this purpose, is divided by a longitudinally extending partition into two sections, and after one of the table sections has become filled, the feed mechanism is usually moved into registry with the other table section to divert the bars thereto and permit the removal of the bars from the other table section.

A primary object of the present invention is to provide means for effecting a movement of the feed mechanism from its position of registry with one table section to the other table section and at the same time preventing a bar or bars which may be coming through the feed mechanism from striking the partition of the table during such movement of the feed mechanism.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth .530 in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings:

Fig. l is a plan view of the feed mechanism showing, in dotted lines, portions of the flying shear table and gathering table; Fig. 2 is a longitudinal cross section through the feed mechanism; Fig. 3 is a transverse cross section through the feed mechanism, taken on the line 3-3 of Fig. 1; and Fig. 4 is a cross section through the feed mechanism, taken on the line 44 of Fig. 1.

The feed mechanism, which is generally designated A, is positioned between the discharging throat of a flying shear table B and a skew gathering table C, which is divided longitudinally as by means of a sectional partition D. The mechanism includes a guide or trough 1, having a bottom 2 and side walls 3, which at one end of the guide, form a constricted mouth, adapted to register with the discharging throat of the flying shear table. At the other end of the guide, a constricted throat is formed by offset portions 3a of the side wall, which provide ledges 3b and 30. At a point intermediate the ends of the member 15, having in its upper edge a V-shaped guide,.the side walls are extended downwardly to form bearings 3d for the support of a freely rotatable roller 4, a portion of which extends through an opening in the bottom of the guide.

A hanger 5 underlies one end of the guide and 5 forms a thrust bearing for the support of a post 6, in the upper end of which is journalled a pin 7. The guide 1 has depending portions through which the ends of the pin 7 extend. This mounting permits pivotal movement of the guide in ver- 10 tical and horizontal planes. A freely rotatable roller 8 is suitably supported underneath the opposite end of the guide 1.

Underlying the other end of the guideand extending transversely thereto is a frame 9, which 15 supports spaced rollers 10 and 11, and an air cylinder 12, in which a piston 13 and its connecting rod 14 is positioned for reciprocal movement. To one end of the piston rod 141s, secured a switch 20 recess defined'by walls 16 and 17.

As clearly shown in Figs. 1 and,3, the piston 13 is at one extreme of its stroke, and in this position the throat of the guide is maintained in registry with one side of the gathering table by the wall 1'? of the recess in the switch 15 and the roller 10. When it is desired to position the guide so that its throat is in registry with the'other sideof the gathering table, air is admitted into one of the ports in the cylinder 12, thereby moving the switch 15 to its other extreme position, as shown in dotted lines in Fig. 3. This movement of the switch prmits the roller 8 to move down into the recess in the switch, and the forward end of the guide, due to its own weight, moves downwardly to the position shown in dotted lines in Fig. 2. When the wall 16 of the recess in the switch strikes the roller 8, the guide is again moved upwardly and into contact with the roller 11.

The operation of the guide is as follows: With the guide in the position shown in Fig. 1, the bars, which may be of considerable length, pass through the mouth of the guideand over the roller 4. The forward end of the bar strikes the side wall an adjacent the ledge 3b, is thereby diverted to the throat of the guide, and continues to pass onto thetable section with which the throat of the guide is in registry.

Assuming that this table section has become filled with bars and that it is desired to feed the bars to the other table section, if the guide were simply moved transv rsely to bring the throat thereof into registry with the other table, and if the forward end of a bar happened to emerge 55 from the throat of the guide during such transverse movement, it will be readily seen that the bar might strike the partition D of the gathering table. Even if the transverse movement of the uide occurred after the bar had started onto the table section, the bar would be caught between the side wall 3a adjacent the ledge 30 and the partition D. In order to avoid the possibility of either occurrence, the guide is moved after a bar has started onto the table section, and by causing the forward end of the guide to be lowered in the manner described, it will be seen that the baris lifted out of the throat of the guide and continues to pass over the ledge 30. By the time the bar has passed through the guide, the transverse movement of the guide has been completed, and the next bar will strike the side wall 3a adjacent the ledge 30 and be thereby diverted to the throat of the guide, passing therethrough onto the other table section.

Othermodes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
