MACHINE FOR WAXING OR-COATING PAPER.

SPECIFICATION forming part of Letters Patent No. 513,030, dated January 16, 1894.

I Application filed July 23, 1892. Serial No. 441,078. (No model.)

To all whom it may concern:

Be it known that we, JOHN W. BLISS and JOHN G. ERWIN, citizens of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Machines for Waxing or Coating Paper or other Fabrics, of which the following is a specification.

Our invention relates to the improved mech anism or apparatus for applying the wax or other substance used, to paper or other fabric, pressing and calendering the web of fabric under treatment, and automatically detecting holes or broken places in the web of paper, and preventing such broken and unmarketable portions from receiving wax or other substance, by severing the web, the object being to provide a combination of mechanism into one machine that will accomplish these results in the most rapid and economical manner.

We attain our object by the apparatus illustrated in the accompanying drawings, in which Figure 1 is a vertical, side elevation of the machine. Fig. 2 is a vertical sectional,front elevation of a portion of the machine. Fig. 3 is a top view of a portion of the machine, and Figs. 4, 5, 6 and 7 represent separate parts or portions of the machine, referred to but not clearly shown in Figs. 1, 2 and 3.

Similar letters refer to similar parts throughout the several views.

Referring to the drawingsz-A A, B B, and G O, constitute the frames or supports on each side of the machine.

Paraffine wax, or other material to be used, is prepared in a suitable receptacle or tank, conveniently located, from which it is drawn into the vat or pan F in which the hollow roll G is located with one third or more of its diameter submerged in the wax or material. When using material requiring heat, steam is conveyed into the roll through steam pipe E. The depth to which the roll G is submerged in the substance in the vat or pan, and the shape of the latter conforming to the surface of the roll, enables us to maintain the wax or material at a uniform consistency and temperature throughout the entire mass. The paper or other fabric N as it passes from the machine on which it has been made, or from rolls, reels or spools on which it'may. have been wound, is passed through the machine in the direction shown by the arrows, between carrying rolls D D, under knife Z, between rolls G and H andbetween carrying rolls D D, and from thence disposed of as desired. Whenthe balance weight M is in theposition shown in the drawings, roll H is sus- 6o pended at a sufficient distance above roll G to enable the operator to readily pass the fabric between the rolls untilit is caught between the carrying rolls D' D. Then by means of the connections between roll H and the hand wheel K-to the latter of which is attached the balance weight M whichcan be moved to any point on the rim of the wheel desired and fastened by set screw-roll H is lowered by turning the wheel in the direction shown by the arrow until the balance weight M has reached a point past the center at the top as shown by the dotted lines M. By this operation roll H as it descends bears the fabric down as shown by the dotted line to the surface of roll G where it receives the wax or other substance on the under side of the web. The weight of roll H together with that of the balance weight M exerts a pressure on the fabric between the two rolls, removing any surplus wax or material from the fabric, thus smoothing and calendering its surfaces. The hand wheel K and the eccentrics J J, are keyed to the shaft L. The straps around the eccentrics and the journal boxes I) b in which roll H operates are so constructed as to receive the ends of the'connecting rods I I which are provided with right and left threads. Thus by turning the hand wheel K, roll H is either raised or lowered and by turning the connecting rods I I, the distance between the eccentrics and the journal boxes is either increased or diminished, to adjust the machine to any thickness of fabric between the rolls G and H. Power is applied to the shaft of 5 roll G at the back side of the machine, either by gearing, or by belt and pulleys and transmitted from the shaft of roll G to the shaft of roll H either by belts, pulleys and counter shaft, or preferably by a pair of toothed roe wheels 0 0. Shown by Fig. 7. These wheels are of peculiar pattern, their teeth extending to an edge about one inch beyond their pitch lines, and the surfaces of the rolls respecthang loosely by their upper ends from the opera-ting in slots in the lower endo'f the anively which prevents their ridingmas Wellies causes them to drop into their proper working position, equalizing the speed of the rolls previous to their surfaces coming together on the fabric between them, thus avoiding any strain on the fabric. Should the webof {1 paper, passing into the machine contain broken or unmarketable paper by reason of holes or broken places, such imperfections are detected by the drags or triggersY which pins f on disks-U, while their lower ends rest; lightly on the upper surface of the fabric in front of carrying rolls D D. The-drags or triggers Y, pins f and disks or cams U may be ofany number :required, .and anyone of the drags dropping through such :im-perfections :in ith e' web, the pinor tooth on :the un- 1* derside of'iit eiseaught rbyithe corrugated :roll. t wihichbeing in 'motion drawsthe'tirigger for -1 ward until the tooth :passesont of connection 3 with the roll t.
