HENRY M. NIGHOLLS, OF LOCKPOR'I, NEW YORK.

COATING-MACHINE.

Specification of Letters Patent. Patented D c 13 1921 Application filed January 8, 1921. Serial No. 435,964.

To all whom it may concern.

Be it known that I, HENRY M. NIoHoLLs, a citizen of the United States, residing; at Lockport, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Coatingwhich will be comparatively inexpensive to manufacture and more certain and efiicient in action than those which have been heretofore proposed.

With these and other objects in view, the invention consists in the novel. details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views:

Figure 1 is a diagrammatic side elevational view partially broken away of a machine made in accordance with this invention;

Fig. 2 is a lan view of the parts shown in Fig. 1; and

Fig. 3 is a sectional view takenon' the line -33 of Fig. 2 looking in the directionsaturate it, it is well known that the strip of. felt in threading through this tank, passes over rolls on the top of the tank I and down under rolls immersed in the liquid asphalt, whence it passes again upwardly over other rolls which are located on top of the tank. It is also well known that should the felt strip not be started exactly right over the first upper roll, or should it get started more or less wrong in its pathv urin the coating operation, a great deal of di culty arises, owing to the'fact that ,the said felt strip will have a tendency to move toward one end or the other of the said rolls.

Stated in other language, there has always been encountered a great deal of difficulty in the saturating tank to get the paper to run straight. The paper is carried out of a straight path sometimes on account of a slippage which it ex eriences due to the properties of the liqui asphalt and to the var ations in the thickness of the paper itself which Wlll cause the paper, even tho gh it be started straight at first, to creep first to one side and then to the other side of the tank. This said creeping of the saturated paper ir felt, will ultimately cause a breakage and therefore a loss in production.

I have observed also that in the manufacture of this said asphalt coated paper the sheet or strip is apt to travel to that side of the roll over which it first gets started wrong, and I have therefore devised a means of lowering or raising one end 01 each of the lOWer or immersed rolls so as to correct the path of the paper in the saturating tank after it has once gone wrong, and thus guide the paper in a perfectly straight path throughout the saturating operation, and have thus succeeded in'increasing the efficiency of the apparatus.

The means by which these desirable results are accomplished will be understood from the following description of the drawings, in which 1 indicates any suitable tank for holding molten asphalt or other liquid coating material, 2, 3, and 4 stationary guide rolls mounted on said tank, and 5 brackets carried on the outside of said tank for holdin the vertically disposed pairs of standar s 6 and 8 resting on the floor 7 or other support of said tank, as best shown in Figs. 2 and 3. The upper portions of one pair of the standards 6 and 8. are joined by a member 9 carrying the screw shaft 10 operated by the hand wheel 11, working in the nut 12 carried by the slidable member 13, all as will be clear from Figs. 1 and 2.

Itthus results that as the wheel 11 and screw shaft 10 are turned the member 13 may be moved up and down relative to standards 6 and 8.

' Each standard 6 is provided with a connecting member such as 14 and 15 slidable on its own standard 6, and overlying the top edge of the tank 1. Likewise, each of the standards 8 is provided with a similar connecting member such as 16 and 17 disposed similarly to the members 14 and 15. Said members 14 and 15 are provided with the lugs 18 through which passes the resilient or easily bendable rod 19 andv said connecting members 16 and 17 are provided with the lugs 20 through which passes the resilient or easily bendable rod 21. The

rods 19 and 21 are provided with the pinions 22 taking in the racks 23 with which the inner pairs of standards 24 and 25 are provided.

It thus results that upon turning the handles 26 carried by the rods 19 and 21,

the pinions 22 will raise and lower the racks 23 and with the latter will move the inwardly pairs of standards 24 and 25. During this last mentioned motion, the connections 14 and 15, 16 and 17, will remain stationary and serve as guides for said pairs of standards 24 and 25, as will be readily understood.

At the lower ends of the pair of standards 24 is supported on suitable bearings a lower roll 30, and at the lower ends of the pair of standards 25 is supported a lower roll 31. The strip of felt 32 or other ma.- terial to be coated, as will be clear from Figs. 1 and 2, first passes over the stationary roll 2 down into the tank 1, under the lower roll 30, up'out of said tank over the stationary roll 3, down into the tank under a second lower roll 31 and up out of the tank over a stationary roll 4, whence it may be passed one or more times down into the-tank again, or else if sufficiently coated, it may be carried out of the tank result, I, in this machine, turn the hand wheel 11 so as to move upwardly or downwardly the cross member 13, whose ends 35 underlie the extreme ends 36 of the members 15 and 17, see Fig. 1, so that said ends 36 will be moved upwardly or downwardly, all aswill be clear from the full lines in Fig. 1 and the dotted lines in Figs. 1 and 3.

The movement of the said ends 36 of the two members 15 and 17 will cause corresponding movements of the lugs 18 and 20 of the said members 15 and 17, and therefore, said movements will cause corresponding movements in the handle portions of the resilient or bendable rods 19 and 21 and in the pinions 22 carried by said rods. But, owing tothe resilient nature of the said rods the pinions 22 located near the ends of the said rods opposite to the handles 26 will not be moved. The movements of these said first named pinions 22 will. cause corresponding movements of the corresponding standard 24 and in the corresponding standard 25 which can slide upwardly and downwardly through the said connecting members 15 and 17 respectively.

Stated in other language, since there is nothing to prevent the said last two mentioned standards 24 and 25 from rising, supposing the movement of the ends 35 to be upwardly, then the corresponding pinions 22 meshing with said standards 24- and 25 will rise with the corresponding lugs 18 and 20 and will carry said standards 24 and 25 bodily upward, thus canting the rolls 30 and 31, as will be clear from Figs. 1 and 3. Should it be desired to cant the rolls 30 and 31 in an opposite direction it is only necessary to lower the member 13, whereupon the members 15 and 17 will be lowered. and with them the corresponding ends of the rolls 30 and 31, so that no matter in which direction the wheel'll .is turned, there will be a. canting of the two axes of the rolls 30 and 31, as is indicated by the lines 40, and 41, shown in Fig. 3.

Suitable pawls shown in Fig. 1, but not lettered, prevent the pinions 22 from turning during the above described operations. When, however, the handles 26 are turned, said pawls are thrown out of engagement by hand.

It'therefore follows that an adjustment of the wheel 11 will slightly cant the axes of the rolls 30 and 31 to the end that the path of the felt or other strip 32 may be kept straight at alltimes.

Of course, it is obvious that other materials than felt and paper may be coated by this machine, and it is further obvious that other materials than asphalt may be used in the tank 1.

Accordingly, it is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore I do not wish to be limited tothe above disclosure except as may be required by the claims.
