EDGAR T. NEWSOME, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO ASBESTOS PROTECTED METAL COMPANY, OF CANTONQMASSAOHUSETTS, A CORPORATION OF MASSACHU- APPARATUS FOR FINISHING THE SURFACES OF FIBRQUS LAYERS.

Be it known that I, Enema T'I-IoMAs NEW- soMri, a citizen of the United States, residing in Boston, county of Suffolk, and btateof Massachusetts,have invented an improvemerit in Apparatus for Finishing the Sur fiiees efl ibrous Layers, of which the following description,- in connection with the accompanying drawings,.1s a speeifieatlon, like letters on the drawings representing l ke (pa This invention relates to apparatus for finishing the exterior sin-faces of a hbrous lily'e'r, and is especially designed and adapt- "out in'thela'ims' at the end of this specificaedgfor, imparting smooth, compact andfirru extrnal surfa ces to protected metal sheets comprising a metal sheet or hody and layers of asbestos, mined-til v'vool or other fibrous material cemented thereto. To this end, the

fapparatus is proi ided with a plurality of "beater rolls havingfiexible members secured tothei njand between which the protected metal sheet is fed. Provision is made for 'app'ly ing a firiishi-ng liquid or composition ;tothe1 ,prqteeting layers as the sheet is fed features of this invention will be pointed tion; r g l Fiiur es 1 and 2', are plan views to be read "tie 'read togetilieref the apparatus shownin ferred tli.

Above the feed rolls a, b, is arranged pipe 10 for supplying aeoating or finishing liquid (:OIXIPOSll'lOT], with which the iihrous layers of asbestos, mineral wool or like non-eomhustible material may" be well moistened, said pipe being closed at its ends by suitable plugs 12 and provided on its underside with perforations (notshown), through which the finishing hquidmay be discharged upon the upper roll a and upon the upper surface of the protected metal sheet, as thelatter is fed through the rolls a, (1, and into the trough when the protected metal sheets are not passiugthrough the feed rolls. The lower roll 71 may revolve in a suitable pan, trough or receptacle 13 in which the finishing liquid accumulates and rises to the level ofaIrovei-liow pipe-let, which is of su'iiiei'cnt height to insure the lower feed roll!) being immersed in the Fur ishing liquidi n'hich is applied to the layer cemented to the lower side of The of the ashes-t the metal sheetby the roll 6. perforated pipe 10'is connected u'itlra'suita hle source ofsupplyfor thefinishing. liquid by a pipe 15 provided with"a-shut-oit' valve 16.

The feed rolls a, b, have cooperating with them a pair of beatei's by which the n1oistened fibrouslayers are hammered or beaten so as to render them smooth," compact and firm. The beaters retferred. to, are preferably made as herein slrown andconsists of a pair-ofirolls or shafts-17,18,1 aving affixed thereto a largenmnber of flexible devices or members, which-for the best results are loops of strings, cords, leather, ete. 20,

In the present instance, the delivery rolls are shownas four in number and two are positively driven, onev of said rolls being employed as the mainior drivingshaft for gears 40, 41'.

The driving shaft 19 is also provided with a sprocket ,wheel 32, which is connected by a link chain 33, with a sprocket'wheel 34 on the shaft of the delivery roll 6, which shaft is provided with a se'eond'sprocket wheel 35,. which. is connected by link chain 36 to sprocket wheel 37-0'n'fthe feed roll 21 nearest to the beaten "The up Jer'.feed roll a, is driven from the lower iced roll b by the The ulley's 28, -29, are substantially' small sotliat the beater rolls may be rotated at a high spwd. i In operation (with the ap aratus herein shown, the protected metals eet,'indicated by the line 140, is placed by the operator 'npon the supporting, rolls 2', Fig. 3, and
