' Application filed June 16, 1903. Serial No. 161,741;

To all whom it may concern:-

Be it known that we, WINFIELD PERRY PEM- BROKE and CHARLES JOSEPH PEMBROKE, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Carbon-Paper Machines, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved machine for coating carbon-paper, removing wrinkles therefrom and preventing theformation of wrinkles therein, and

for marking the paper; and with this and other objects in view the'invention consists of a machine of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form'a part, in which the separate parts of our improvement are designated by suitable reference characters in each-of the views, and in which Figure 1 is a right-hand side elevation of our improved machine; Fig. 2, a front view thereof; Fig- 3, a sectional side view of the left-hand side of the machine, and Fig. 4 a transverse section of the machine in the'position shown in Fig. 3.

In the practice of our invention we provide a main frame (0, comprising suitable side members (0 connected in any desiredway, and a rear extension a and in the front lower portion of this frame is mounted a dopebox (o Rearwardly of the main frame and supported by the extension (0 is a paper-roll 6, provided with a shaft or end trunnions 6 mounted in bearings or supports If, the upper part 6* of which is held in place by means of screws or bolts 6 so that friction may be applied to the shaft or trunnion of the paper-roll b.

At the front of the main frame and revolubly in the dope-box a is a dope-roll c, the

shaft or trunnions of which have bearings at 0 and ab'ovethe dope-roll c and slightly in front thereof is mounted an ironing-roll d, having shafts or trunnions (Z At the back of the machine and at the top.

windingroll 0 is provided with a sprocket wheel eflas shown in Figs. 1 and 2, and said shaft is also provided with a cone or stepped pulley e.

Mounted in the left-hand side of the main frame is a stub-shaft z, provided with a cone or stepped pulley c and the pulleys e" and i are geared in connection by a belt or band 11 The stub-shaft is provided with a pinion i which meshes witha pinion i which operates in connection with a gear wheel i on the shaft of the dope-roll 0, and the object of this gearingis to turn'the dope-roll in the same direction as the paper-roll t in the operation of the machine, as hereinafter described, and

the object of the gearing consisting of the cone or stepped pulleys e and i and the belt or band i is to'give the dope-roll c a variable speed with relation to the speed of the winding-rolle.

Passing over and around the sprocketwheel a on. the shaft c is a drive-chain 7a, which is crossed'intermediate of the windingroll 0 and the ironing-roll d and passed around a pinion 71? on the shaft of said ironing-roll. The shaft of the ironing-roll d is also provided with a sprocket-wheel and the shaft of the cold-roll f with a similar sprocket-wheel 70 and passing around these sprocket-wheels Z0 and it is a drive-chain K0 and the sprocketwheels 70 and 7c are of the same size and provided with the same number of teeth; but the sprocket-wheel 70 on the shaft ofthe ironingroll is but one-third of the diameter of the sprocket-wheel on theshaft of the winding-' roll 6, the object of this being to give the ironing-roll a speed three times greater than that of the Winding-roll. The shaft of the cold-roll f is provided with a pulley f which is preferably of the same diameter as the coldroll itself, and mounted on this pulley is a belt j', which is crossed between the cold-roll and the smoothing-roll and passed around a pulley f on the shaft of said smoothing-roll, and the diameter of the pulley f is preferably about onequarter that of the pulley f whereby the speed of the smoothing-roll g is preferably made four times that of the coldroll.

The means for marking the paper is of the following construction. A disk on is secured to the shaft of the ironing-roll, and this disk is provided on its outer face with radially-arranged convolutions m and arranged longitudinally of the ironing-roll and at the front upper portion thereof are bars or, three of which are shown, and these bars are connected in the form of construction shown with segmental boxes 71?, which rest on the bearings of the shaft (Z and are movable thereon, and one of said bars is provided with a projecting member 72 which projects downwardly radially across the face of the disk at, and said member a" is also provided with a spring-finger 0, which bears on the inner face of said disk, and as the shaftd is turned the disk on will give the bars a an oscillating movement longitudinally of the ironing-roll. The bars 77/ are provided with longitudinally-arranged and inwardly-directed teeth, needles, or reeds, or similar devices which are adapted to bear on the surface of the paper as it passes over the ironing-roll, and this gives the paper in the operation of the machine as hereinbefore described a mark which may be seen when the carbon-paper is held up to the light.

The shaft (Z of the ironing-roll is the powershaft of the machine and is provided with a pulley 9', to which in practice is applied a band, belt, or similar device, and the machine may be driven by any suitable power.

In practice the paper .9 is wound on the paper-roll b, and'one end thereof is passed over the smoothing-roll g beneath thetensionroll 7t, over the roll 0, in front of and over the ironing-roll (Z, backwardly over the coldrollf, and under and around and secured to the winding-roll It will be understood that the dope may be placed in the box a" atany time, but is preferably placed therein after the paper has been arranged as described, and when the power is applied the ironing-roll (Z, the cold-roll f, the winding-roll c, the paperroll (Z, the smoothing-roll g, and the dope-roll 0 will be turned in the direction of the arrows (1:, as shown in Fig. 1, and from this it will be seen that the ironing-roll (Z and cold-roll f are turned in a direction opposite to that of the other rolls. The smoothing-roll gis intended to take out any wrinkles that may be in the paper 5 and also prevent the formation of any wrinkles therein, and the object of the tensionroll it is to facilitate this operation and to also give a greater surface of the paper for the dope-roll c to operate upon, this last object being accomplished by placing the tensionroll 71/ comparatively low. It will also be understood that the paper-roll is also under tension by means of the bearings thereof, and this tension may be increased or decreased, as desired, and this also aids the smoothingroll (I to accomplish the result for which itis intended. The dope is applied to the surface of the paper as the latter passes over the dope roll 0, and the amount of dope deposited upon the paper and the condition thereof on the paper may be regulated by the speed of the dope-roll, and that speed, as hereinbefore stated,is variable and may be regulated by means of the belt i and the stepped or cone pulleys c' and 7: and the movement of the dope-roll c in the direction in which the paper is moved also aids in properly distributing the dope on the surface of the paper.

It will be understood that the bars a and their connected parts may be detached whenever necessary in order to pass the paper around the ironing-roll, and said bars may be dropped back into position before the machine is set in motion. It will also be uuderstood that our invention is not limited to the means herein shown and described for giving the bars 92 a movement longitudinal of the ironing-roll, and any suitable mechanism may be employed for this purpose.

The ironing-roll (Z is preferably moved at a much greater rate of speed than the dope-roll, as hereinbefore stated, and also at a much greater rate than the speed of the windingroll, and as the paper passes from the ironing-roll it is held taut and perfectly smooth by the tension devicehereinbefore described, and in this operation of the ironing-roll the bars 02, as hereinbefore described, are oscillated longitudinally of said roll, and the teeth, fingers, or reeds p on said bars bear on the doped surface of the paper and form thereon the mark hercinbefore referred to. this mark being undulated or wave-like in appearance. transversely of the paper. The mark produced in this manner forms no part of the invention herein described and claimed. but is made the subject of a separate application for Letters Patent of the United States filed by us on the 27th day of March, '1903, Serial No. 1et$),795.

After the paper leaves the ironing-roll it passes from the cold-roll f, the speed of which is the same as that of the ironiugroll, which chills the surface of the paper and thoroughly dries the dope, and from the cold-roll j" the paper passes to and is wound on the windingroll (a, from which it may be removed at any time, and this winding-roll 1 may be of any preferred diameter.
