Application led February 1, 1919. Serial No. 274,464.
To all whom z't may concern:
Be it known that I, HARRY M. FRENCH, a citizenof the United States, residing at Nor.- wood, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Coating-Machines, of which the following is a specnication.
rlhis invention pertains to coating machines and has to do more particularly with that classwherein a coating layer or lilm of paint is applied to a continuous strip or web of fabric, such, for instance,vas a-sheet of felt employed as floor covering or the like.
lt is essential to the production of a commercial article that the paint should be applied evenly and without streaks or stripes, and' the present invention has for its object the production of a mechanism automatic in its operation which will effect the even distribution of the paint to the surface of,
the web or sheet.
The structure is illustrated in the annexed drawings, wherein:
Figure 1 is a front elevation of the mechanism, the paint reservoir being omitted;
Fig. 2 a top plan view thereof; L
Fig. 3 a transverse vertical sectional View on the line Hl-IH of Fig. 1; y
Fig. 4 a similar view on an enlarged scale;
Fig. 5 a vertical sectional view on the line V-V of Fig. 4;
Fig. 6 a horizontal view on the line Vl* Vl of Fig. 4;
Fig. 7 an elevation of the ratchet mechanism and allied parts; and
Fig. 8 a detail section on the llne VH1- VH1 of Fig. 4. j
The web to be coated is designated by the numeral 1. It passes over a guide roller 2 to and about a feed roll or drum 3, said roller and drum being supported in suitable standards or frames 4, 4. The sheet is drawn forward about the drum 3 by suitable means (not shown) and paint or other coating material is applied thereto by a roller 5 to which paint is constantly supplied by suitable means, as, for instance, feed rollers 6 which are immersed in the paint present in a feed trough or reservoir- 7, Fig. 3.
Where paint is the substance applied to the web or sheet 1 by the ductor roller. 5, the paint on the sheet after it passes out of contact with said roller, will present a more or less streaky or ridged eHect and to smooth or evenly spread the paint l employ a doctor roller 8. Said roller is suspended by and has its bearings in two linksor arms 9 pendulously supported from machine screws 10 which take into brackets 11 secured to the inner faces of the main supporting frames or standards 4. Fach of the arms 9 is provided with an outward extension 12 at its lower end to which is pivotally attached a link or radius bar 13 and extending through each of the bars at their outer ends and secured thereto is a shaft 14. rlhe ends of said shaft find their bearing and support in eccentric bushings 15 mounted in the lower outwardly extending portions brackets 11. rlFhe bushings may be shifted in their bearings and the shaft 14 thrown toward' or receded from the doctor or spreading roll 8, the bushings being fastened in their adjusted position by bolts 16 which pass through slotted extensions or fianges 17 formed on the bushings and into the brackets 11. Shaft 14 is provided with hand wheels 18 and by turning the shaft thereof the roll 8 may be forced toward or removed from the web or sheet 1 through links 13 and extensions 12, which in effect form toggles. The degree of pressure exerted by the roll 8 upon the sheet 1, or more specifically upon tliecoating of paint carried thereby, may be readily determined by the adjustment of the eccentric'bearings 15, and by merely imparting a partial rotation to the shaft the roll 8 may be quickly wit; drawn from operative position and as expeditiously advanced to such position.
Roller 8 normally remains stationary, that is it has nocontinuous rotary movement, but inasmuch as paint skins and' other extraneous substances will from time to time collect of the upon the roller, it is found desirable to par-` tially rotate the roller periodically so as to effect a clearing thereof and preventing streaking which would otherwise occur. To
this end the axle of the shaft is prolonged at one end, as at 19, Figs. 5 and 6, beyond the link or hanger 9 and a ratchet wheel 20 is secured thereto. A bell crank lever is fulcrumedupon said extension 19, one arm 21 coperating with a cam 22 rotatable with drum or roll 3, while the opposite end' 23,
see more particularly Fig. 7, carries a pawl 24 which coperates with the ratchet wheel 20. The pawl is held in operative relation with wheel 20 by a spring 25, one end of which is attached to a pin 26 carried by the pawl, while the opposite end is secured to a pin 27 carried by an upwardly extending coated web then passes in contact with thev finishing or spreading roll 8, which, as above noted, smooths out the paint so that the web as it leaves the roll 8, has an even and continuous coating thereon. Once for each revolution of the drum, assuming there is but one cam 22 employed, the bell crank lever will be rocked and as a consequence roll 8 through the pawl and ratchet mechanism will loe turned the distance of one or more teeth, depending, of course, upon the amplitude of movement imparted to the bell crank. Such partial or step-by-step rotation will carry any extraneous matter upwardly away from the line of contact betweenI the roller and the advancing web, and
if carried over on the roller such matter may be readily removed. The roller may also be rotated through manipulation of handle 28, if for any reasonit becomes desirable so to do, as when first starting up the machine, or when, streaking occurs just after the roller has been shifted by the cam.
While I have referred to paint as the substance to be applied to the web, it is, of course, conceivable that the structure may be employed in connection with the application of coatin s of various kinds.
What is clalmed is l. In a machine for applying a coating to a web of material, the combination of means for advancing the web; means for applying a coating to one surface thereof; means for smoothing said applied surface; and means for 4periodically shifting said smoothing means. ,n
