CHARLES W. MAYER, 0F ROCHESTER, NEW YORK.
SATURATING-MACHINE.
Application led April 18, 1917.
To all whom t may concern Be it known that I, CHARLES W. MAYER, a citizen of the United States, residing at Rochester, in the county' ofl Monroe and State of New York, have invented certain new and useful Improvements in Saturating-Machines, of which the following is a specification.
Thisinvention relates to saturating machines. Particularly it relates to machines for saturating paper or other fabricated web with substances which may be forced thereinto by the combined action of heat and wiping-in mechanism. It is to be distinguished from coating machines and from impregnating machines, as will be seen.
The object of my invention is to saturate the web with any desired substance capable of 'being forced into the same by using the minimum amount of such substance, as distinguished from impregnating a web by submersion, or squeezing in, or any of the common methods which effect filling without regard to the quantity of material used. Also, to be able to so saturate webs of the lightest tissue with the minimum amount of saturating material. As a concrete statement of this object, this machine fully saturates and renders waterproof a paper web weighing but eleven pounds to the ream (24 x 36 inches) using less than one-half pound of wax to the ream. Or, further to show the attainment of this object, it saturates perfectly a web of paper tissue weighing seven pounds to the ream (same size) without any strain upon the web lor danger of tearing the same.
A' further object of this invention is to eliect such saturation Awithout employment of the various submersion, squeezing operations, coating and heating-in operations, and the like which produce either creasing, wrinkling, tearing the fabric, or distorting or buckling the same, especially withv a very light or tissue fabric; and furthermore, a most important object is to provide full control at all times with reference to speed, pressure and amount of saturating material employed.A
A further object is to effect the saturation by the combined action of preheating and wiping-in the saturating material by a resilient buff while the web is firmly held against a heated drum.
I shall describe in v invention adapted to saturating a web of paper with wax. But
Specification of Letters Patent.
Patented Dec. 24, 1918.
Serial No. 162,988.
while such is a main, typical use, I do not limit my invention thereto.
Since I employ a number of mechanisms well known in the art, I shall not describe them in detail, but shall assume persons skilled in the art to be familiar therewith.
Referring to the drawing herewith, which is a side elevation, lis the stock spindle upon which the roll of fabric is placed. This spindle is provided with adjusting and tensioning means for regulating the travel and tension of the paper. From this spindle the web passes over the preheating cylinder 2. This cylinder is heated by steam or hot water in well-known manner. It is positively driven b v gearing connecting it with the power-shaft 17 which is driven by a pulley 18 belted to any desired source of power.
After passing over this preheating cylinder and contacting a substantial arc of its surface, it passes down and around the large drum 3. This drum is likewise heated and heated to a high temperature, and is positively driven by gearing connecting it with the cylinder Q.
Thus before the web comes in contact with the buff 4, it is thoroughly heated through from both sides, so that it attains substantially the same temperature as the drum 3. This thorough preheating is essential to saturation with minimum amount of material because, whatever the temperature of the material applied, or whatever the temperature of the buff, for unless the temperature of the web is substantially that of the melted material, full saturation will not occur andthe capillary flow will be checked, or stopped, with the result that there will be but sen'ii-saturation or semi-coating. 9 is steam or water heated piping and the heat rising therefrom keeps the buff hot, and a deliector l() directs the heat over the peripher)Y of the buff.
The butf l is a built-up bul-f, made of factory cloth cut in disks, placed over a square shaft and compressed and held axially of the shaft. It is compressed suliiciently to give it rigidity, and still be sufficiently iexible to flatten out in Contact. with the web to give a three or four inch rub against the web. Since this bul-l' is run at the speed hereafter described, the centrifugal action tends to keep the saturating material from soaking in toward the axis and thus keep it upon the periphery for application to the web.
l'lO
' and which is heated in well-known manner.
This coating roll contacts the buff, and rotating in the same direction to that of the buff, applies the heated liquid to the bud.
An adjustable doctor 12 removes the surplus liquid carried up bythe coating roll, and serves initially7 to regulate the amount of material to be applied.
The web, after passing over more than one-half of the periphery of the drum 3 after leaving the buff, during which time the saturat-ing substance is thoroughly heated into the fiber, passes around the roll 14. This roll 14 is gear-driven from the drum 3 and has the same peripheral speed. It is a cooling roll, cooled with water circulation; but under some conditions of fabric 0r saturating substance, it may be heated, through hot and coldpipe connections in well-known manner, to prolong the heating-in processpermitting the roll next described to perform the cooling.
From the roll 14 the web passes around the cooling roll 15. This roll is water cooled, is driven from the roll 14 by gearing, and has the same peripheral speed.
From the roll 15 the web passes to the wind-up roll 16, which is belt-driven by a belt 19 driven from the shaft 17. An adjustable belt-tightener 20 is provided to regulate the pull of the wind-up roll 19.
The coating roll 5 is driven by sprocket and chain connection 21 with the shaftv of the drum 3, through changeable gearing of well-known type.
With such general description, I will now describe the adjusting and change-speed mechanisms more specifically. The buff 4 is adjustable in two directions,-irst, toward and away from the drum 3, and second,vtoward and away from the coating roll 5. Taking the latter adjustment first, the bearings of the buff 4 are mounted in yokes 6 which are pivoted on the shaft of the coating roll 5 and which have slots or openings for the bearings of the buff 4. Rigidly con nected to the bearings of the buff 4 are racks 7, which are in mesh with gears 24. Secured to the yokes 7 are gear-segments 26, and in these gear-segments is journaled a transverse shaft 27, on which are rigidly secured the gears 24. A crank 28 on this shaft serves to rotate the gears 24 and thus to move the buff 4 radially toward and away from the coating roll Gears 8 are rigidly mounted on a transverse shaft 11 which is journaled in bearings on the frame of the machine, and which shaft has a crank 13 which serves to rotate the gears 8, swinging thesegments 26, and thus moving the buff 4 circumferentially of the coating roll 5 and toward and away from the drum 3.
This adjustability of the buff serves not only t0 regulate the amount of material applied, but with the Wear of the cloth ofthe buff in use, such adjustment is necessary, as is also the other adjustment toward the drum 3.
While movement of the buff 4 toward and away from the coating roll 5 is tangential to the drum 3, the diameter of the drum is 30 so great and theadjustment of the buff so slight thatl no substantial disturbance of the adjustment between the buff and the drum occurs.
The change-speed gearing for varying the speed of the buif is indicated in broken outline at 25, and the change-speed gearing forv the coating roll is similarly shown at 29. In both cases the change-speed is well-known sliding-key construction which can be operated from one side of the machine while it is running. Other known forms of changespeed apparatus may be em loyed, but I have found this type the most a aptable.
While the operation will be clearly understood from the foregoing description, it should be noted that, aside from the buif and coating roll, all the other web-contacting rolls have a common peripheral speed, so that at whatever speed of operation, there is no undue strain upon even the lightest tissue. It is also to be noted that by having the buff and the coating roll both adjustable as to contact and as to speed as well, perfect saturation with minimum amount of material to a degree wholly unattainable by the revious methods above referred tocan be .o tained.
Having thus described my invention, I claim 1. In a web saturatingl machine, the comb'i- 110 nation of a heated drum over which the web travels, and a combined liquid-applying and buing roll traveling in contact with the web on said drum.
2. VIn a web saturating machine, the combination of a pre-heating roll over which the web passes, a heated drum over which the web passes, said drum and roll being located on opposite sides of the web to heat both sides thereof, and a combined liquid-applying and buliing roll traveling in `Contact with the web on said drum.
3. In a web-saturating machine, the combination of a heated drum and a heated roll between which the web Ipasses to heat both sides thereof, and a combined liquid-applying and batting roll coperating with the drum, the web passing between the drum and the bufiing roll subsequent to its passage between the drum and the heating roll.
4. In a web-saturating machine, the combination with a relatively large heated drum, of a heating roll, and a combined liquidapplying and buffng roll,` said rolls cooperating with the drum at differentradial positions, the web passing first between the drum and heating roll and then between the drum and buiing roll.
5. In a web-saturating machine7 the combination with a relatively large heated drum, of a heating roll, and a combined liquid applying and buiing roll, said rolls coperating with the drum at different radial positions, the web passing irst between the drum and heating roll and then between the drum and buiiing roll, the latter traveling at greater peripheral speed than the drum.
6. In a web-saturating machine, the combination with a drum over which the web travels, of a combined liquid-applying and buiing roll acting on the web as it travels on said drum, a liquid supply roll cooperating with the buiiing roll, and means to adjust the buffng roll with respect to the drum and also with respect to the supply roll.
7. In a web-saturating machine, the combination with a drum over which the -web travels, of a combined liquid-applying and buiing roll acting on the web as it travels on said drum, a liquid supply roll coperating with the buiiing roll, means to adjust the bufiin roll radially with respect to the supply ro l and tangentially with respect to the drum.
8. In a web-saturating machine, the combination with a drum over which the web travels, of a liquid-supply roller, and a combined liquid applying and butling roll cooperating with both the drum and the sups ply roller, said buiiing roll being adjustable with respect to either the drum or the roller, without materially varying its adjustment with respect to the other.
In testimony whereof I have hereunto set my hand and aliixed my signature in the A presence of two subscribing witnesses.
