MCABTHUR, DECEASED, ASSIGNOR T0 AMERICAN SHEET AND TIN PLATE company, or PITTSBURGH, rENNsYLvANrA, A conforma-roar on NEW JERSEY coNvEYnR Application led February 8, 1928. Serial No. 252,850.

.between a heating furnace and hotmill, and

has for its object the provision of apparatus which will materially reduce the labor necessary in handling said sheets or plates and also will provide hotter platesthan the hand methods eretofore generally used.

'I-Ieretofore, the sheets or plates have been enerally removed from the heating furnace.

hand and the o erator would throw or s ide the sheets or p ates across the mill floor to the hot vmill roller. The sheets would then lay on the cold-mill iloor untilthe roller was ready for them and contact, even for a short time, with the cold mill floor would materially cool the sheets or plates. v

The mill operator or attendant would then be compelled to struggle with the sheets and gri them with his tongs, then lift them up and) feed them into the hot mill/rolls.

The present apparatus provides a conveyer for feeding the hot sheets from the furnace to the mill and then rovides an elevated support lwhich holds t e sheets in elevated position in readiness for the roller to swing them into the bite of the hot mill rolls. Furthermore, the support is provided with spaced supporting means which have a materially less cooling eifect than a solid plate or floor would have. l

In the drawings- Figure 1 is a side elevation partly in section showing my improved apparatus applied to a hot mill.

Figure 2 is a plan thereof.

Figure 3 is an enlarged plan of thecaster table for receiving the heated sheets from the conveyer. 1

Figur'e 4 is a side elevation thereof.

Figure 5 -is an enlarged sectional detail showing the manner in which the ball casters are mounted.

Figure 6 is a side elevation of a slightly.

modified form ofxapparatus in which the caster table is dispensed with.

e Figure 7 is a' sectional elevation through the sheet receiving skids of the modified ape paratus of Figure 6.

Referring more particularly to the drawings, the numeral 2 designates the heating furnace as a whole which has its heating chamber 3 provided with a disk roller-ty e conveyer 4 adapted to continuously feed tlie sheets being heated through the furnace and discharge the heated sheets through an openin or doorway 5.

he particular type of furnace shown in the present drawings forms the subject matter of a separate application and, therefore, will not be described in detail. It will also be understood that any suitable continuous sheet heating furnace may be used in carrying out the present invention.

A gravity conveyer A is arranged to receive the heated sheets as they are discharged from the furnace 2. The conveyer A comprises a supporting framework 6 having upper siderails 7 which are inclined downwardly from the furnace toward the hot mill B. A plurality of disk conveying rollers 8 are journaled in the si de-rails 7, the disks of 'one roller 8 being staggered with relation to the disks of the next roller. The lower or mill end of the conveyer A terminates in a supporting table C which is located slightly to the one side of the mill.

The table C may be of any suitable construction which will support the hot sheets above the mill iioor in readiness to be grasped by the tongs in the hands of the mill attendant or operator, and which will support the hot sheets at spaced intervals so as not to unnecessarily/*cool them.

In the present embodiment of my invention, I havel shown thetable C as composed of a ball bearing caster table, which consists of a base-plate 10 supported by suitable framework 12, and having spaced apertures 13 therein which form sockets to recelve beari cups 14 each of which contains and forms a earing for a ball caster 15. The cups 14 have retaining flanges 16 which overlie the base-plate 10, and a cover-plate 17 having apertures 18 therein is fitted over the cups 14 and overlies the flan s 16. l

The cover-plate 1 is secured at spaced in- 2 amm tervals, as at 19, tothe base-plate, and serves to revent displacement of t e bearing cups. uitable side guiderplates 20 are arranged alon each side of the conveyer A to prevent 5 disp acement of the sheets as they `are travelin from thel furnaceto the mill. a

n operation, the sheets will move from th 1 furnace down along the conveyer A by gravity and since the rollers 8 are of the disk-type,

lo there will be the minimum of contact between the sheets androllers and consequently little cooling will take place. The `conveyer A will deliver the sheets to the table C where the' sheets will be supported on approximately a ,5 line with the bite of the rolls of the hot mill by the casters 15. The casters 15, being spaced, will form spaced oints of contact and, therefore, again the s eets will be subjected to a minimum cooling eiect.

The table C, being positioned as shown,

materially reduces the labor ofthe mill attendant or operator since it is notnecesszary vfor him to lift the sheets from the floor up into the bite ofthe rolls as heretofore.' j

In Fi res 6 .and 7, I have shown a slightly f modifie form of sheet handling apparatus a in which a pair of spaced upwardl inclined skids C1 are rovided to receive't e heated sheets insteadp of the table C.

While I have shown and described one specific embodiment of my invention itwill4 be understood that I do not wish tp be limited thereto since various modificationsv may be made without departing from the scope thereofas defined in the appended claim.

c1aim A sheet conveyer mechanism for conveying hot sheets to a stand of hotrolls in a sheet rolling mill, com risin an inclined avity-v 4o conveyer having sk-li e conveyer-ro 1ers onl f which the sheets ride, and a horizontalcaster table at the lower end of said conveyer, said table being positioned verticallyso that the tops of the casters are approxlmately on a line with the bite of the rolls of the mill to which the sheets are being conveyed, and said casters bein adapted toy form spaced points of sup rt or the heated sheets from which the mi attendant may readily feed the sheets 5o into the mill.

In testimony whereof, I have hereunto set m hand. y ARTHUR MOAR'IHUR.`
