3 Claims.

. 1 The present invention relates to means to facilitate the marking of either the end or side edges of pieces. y

One object of the invention is to provide simple yet eiective means to facilitate the stamping'of identifying marks on the ends as Well as the sides of slabs, billets, or the like, in such manner that the marking is always, visible when such workpieces are .stacked in storage.

A further object is to provide means for supporting fluid-operated marking devices on an arm swingable to a predetermined position for engagement with either the end or side edge of the slab or like'workpiece, in such a way that the vmarking devices have a swivel connection with the arm so that the latter need not4 necessarily be accurately aligned with the end or side 1 edges of the workpiece.

The above and further objects of the invention will be fullyapparent from the following detailed disclosure when read in connection with the accompanying 'drawings and the appended claims.

In the drawings: Figure 1 is a plan view of a: slab or billet -runout conveyor table having juxtaposed thereto improved slabs, billets, or similar work- Y 2 A holder 30 is swiveled ona vertical. bolt I2 'which is adapted to be adjusted at a desired radial distance from the axis of rotation of the pedestal VHi. An angle 34 is secured bya bolt 36 in oneA of several holes '38 located'at radial distances to suit the particular work to be marked. The angle 34 acts as a stop to vlimit the extent of swiveling motion of the holder about "the axis of the bolt 32'. The holder carries one or more a marking device incorporatingl the herein.

claimed invention.

Figure 2 is a side elevation of the apparatus of Figure 1. 4

Figure 3 is a section on line IlI-III of Fig- -ure 2.

- Figure 4 isa fragmentary plan of Figure 3.

Figure 5 is a horizontal section on line V--V of Figure 3.

Figure 6 is a detail section on line VI--VI of Figure 1. n

Referring in detail to the drawings, I0. represents one side frame of a conventional form of slab or billet run-out table, usually equipped with a multiplicity of power-driven conveyor rolls I2.

Mounted in juxtaposition to the run-out table is a bracket or frame memberl I4 rotatably supporting a pedestal IB in aligned bearing portions I8. At its upper end the pedestal carries a stub shaft 20 serving as a fulcrum support for an arm 22, which is apertured at 24 to provide clearance with respect to the upper vend of the'pedestal.-

An adjusting screw 28 is threaded through the hub-28 of the arm, and provides means for adcylinder 56 having asuitable piston therein for reciprocating a piston Vrod 58 carrying a rack 80 meshing with a pinion 62 secured to the lower portion of the pedestal I6. A valve 84 controls the supply of motive uid fed Afrom pipe -IB to the cylinder 5B by way of a pipe-68. A plunger 'I0 -reacting against a spring 12 carried in a cylinder 14 suitably mounted in a bracket I6 serves to cushion the swinging action of the parts.

In normal operation, for ,marking identifying numbers or letters on the end face e of the slab or billet, the arm 22- will occupy the full-line position shown in Figure 1. With the parts in this position, it is merely necessary for the operator to admit compressed air by a manipulation of the valve 50, whereupon the pneumatic hammer 42 will causethe tools. to indent'suitable marks on the end edge e of the slab or billet. By ma.- nipulating the valve 64, compressed air is admitted to one end of the cylinder, thus swinging l the arm 22 to the dotted-line position indicated at 22B. This will move the marking devices 44 to the position shown indotted lines, so as to facilitate applying identifying marks to the side edge s of the billet. When in this position it will be apparent that the swivel connection 32 provides an arrangement whereby the holderY can be propi erly brought into substantial parallelism "with the justing or leveling the armso that identifying marks or indicia can be located or spotted with precisionon either the end edge e or the side edge sof the slab or billet B supported on the table.
