METAL-HANDLING TABLE.

Application filed April is, 1924. Serial No. 706,958.

-My invention relates to devices particularly adapted to receive hot metal as it'comes from the shears in rolling mill practice, such devices having a function of delivering the metal received thereon, upon another table beneath.

It is my object to provide a machine which will take the piece direct from the shears, and will have sufiicient resilience so that when the shears are handling heavy pieces w shears, or any other conveyor, and then to provide means of separating the rollers while at the same time dropping the sheet through onto another conveyor or any suitable table.

In connection with the above features I provide for a table which is adjustable for different widths of piece, without interference with a drive which operates in all positions without special adjustment. I

These various objects and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Figure 1 is a top plan view of the device.

Figure 2 is an end elevation of one side thereof, partly in section.

Figure 3 is an end elevation on a smaller scale of the whole machine.

Figure 4 is a side elevation of the whole machine.

Referring to the drawings, it will be noted that considerable detail is omitted, it being understood-that conventional beams and the i like will be employed for the purpose of supporting the parts. The shears is indicated at 1 with the upper blade thereof at 2. Mounted on standards 1 in front of the shears is a cross beam 3, and a heavy shaft or axle 3* for the two ends of the machine. on which beam and axle the two halvest of 4 X- tending lengthwise over beam and axle are shafts 1 and 4, which are right and left hand threaded, to engage the saddles of the table parts and adjust their position laterally. These shafts are driven simultaneously by means of a hand wheel 5, and a train of beveled gears generally ,noted at 6 (see Figure 1). The lateral shafts 6, form- ,24 between the cross pieces.

ing part of the gear train at 6, as indicated, are at a slant because of the fact that the axle 3 is below the cross beam 3.

On the beam 3 are two sliding

saddles

8, 8, in which are slidably mounted pairs of heavy bars 9, which bars are maintained upwardly by springs 10, 10, thereon. The saddles have nut elements 11, through which the screw shaft 4 passes, so that revolution of the screw shaft moves the saddles to and from each other.

The bars 9 are formed with hooks at their lower ends which engage cross bars 12, held in the lengthwise housings of the device. As shown in Figure 2 these housings, marked 13, may be formed of side channels and top and bottom plates of metal.

At the end of the device away from the shears the housings 13 are formed with saddles 14:, which ride and rock on the axle shaft 3. These housings also have journals 15 for the drive shaft system of the table rolls, and nut elements 15 for the screw shaft 4*.

Secured on the underside of the side hous- Ings all along the two halves of the mechanism are journal boxes 16 for the table rolls. The rolls are shown at 17, and their spindles or shafts 18 pass through the said boxes, and terminate in shoulders or studs, 19, whereby the spindles are pulled lengthwise, thereby spreading the rolls apart, as will be described.

The side housings also carry knock-off bars 20, shown as bars of angle iron, which are so arranged as to wipe over the tops of the rolls, on the two halves of the machine as said rolls are withdrawn.

Down the center of the table, above the rollers so as not to interfere with the feed from the shears'is a screw shaft 21, which operates the gauge 22. The gauge has a threaded portion through which the screw shaft passes, and isheld against revolving by side bars 23, supported on the beam 3, the screw shaft being rovolubly held in a journal At the end of the table away from the shears the screw shaft 21 terminates in a head 25, held against lengthwise motion and revolved by a hand wheel 26. The gauge has been omitted from Figure 4., to expose other mechanism. It depends to a point between the rolls and acts as an abutment for the metal piece as it is fed through the shears, indicating the point at which the shears should sever the piece to give the desired length.

The rolls are driven as follows :-On the spindles 18 are sleeves 27 which lie between the pairs of journals 16 for each roll spindle, thus being held against lengthwise movement, said sleeves being keyed to the spindles. On the sleeves are fast sprockets 28 for chains 29, and sprockets 30 from which power is transmitted from every other sleeve to the sleeve next adjacent. By this means some of the rolls are driven direct and some driven from the rolls next to them.

The drive for the rolls is independent, being from a pair of motors 31 mounted on the two housings. The motors drive by means of gear trains generally noted at 32, the shafts 33, which have beveled gears 34 thereon. The gears 34 drive each a. sprocket shaft 35, mounted on top of the side housings along with the motors and shafts, there being two sprocket shafts on each half of the machine. Sprockets in pairs as at 36, drive chains 29, and chains 37 extend from the driven sleeves 27 to the sprockets 30 on adjacent sleeves as has been noted.

The mechanism for withdrawing the roll spindles, thereby separating the rolls laterally of the machine. and droppingthrough any metal lying on the rolls. is by means of an air or steam cylinder 40, the piston rod 41 of which has a crank 42 thereon, said crank serving to rock a shaft 43. The shaft 43 is mounted in journals 44, on the two side housings, and preferably has a universal joint at 45 to provide for uneven position of the two sides of the machine.

This shaft 43 has beveled gears 45 at its ends, the shaft being splined to the gears and the gears held against moving with the shaft by means of attachments on the journal boxes at the ends of the shaft.

Mounted in journals 46 along the outside of the two side housings are shafts 47, which have gears 48 meshing with the gears 45, so that the shafts 47 are rocked when the piston rod-is set in motion.

The shafts 4-7 have cranks thereon, as at 49. which engage the studs in the ends of the roll spindles. so that the rocking of the two shafts 47 will withdraw the rolls, resulting in a dropping of the metal held thereon.

The roll withdrawal and the lateral movement of the two side housings 13, are simultaneous and alike on both sides of the machine, being driven each from a single power means. The two side housings carry the entire table mechanism, and should the cross piece 13' at the forward end of the housings be depressed by a piece of metal as it is acted upon by the shears, or by'the shear plunger, if desired, the springs and hook bars, supporting the housings at the front will permit the entire device to give downwardly, while it will rock on the axle shaft at the rear. The side-shafting 6 of the lateral adjusting mechanism for the two housings is mounted at the front of the machine by means of rocking journals 6 (Figure 1), and at the rear by rocking journals 6. Thus these shafts will not 1nterfere with the depression of the table by the shears.

The machines constructed in accordance with the structure shown and described, operate very rapidly and smoothly to receive pieces from the shears, and drop them through onto any other form of table lying directly beneath. Such a table is indicated by means of a driven roller 50, and crop buckets 51 are shown, as a. means for transporting crops from the shears. When cropping the table device described is rendered inefiective by withdrawing the rolls so as to leave a clear space through which the crop will drop when out ofi by the shears.

It will be evident that the essential objects of my invention can be accomplished by the use of other mechanical equivalents for the mechanical devices described, as being employed to accomplish the several functions.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
