DEVICE FOR DISPENSING, COATING AND CUTTING PAPER WEBS Filed DeC. l5, 1961 United States Patent O 3,199,490 DEVICE FOR DISPENSING, COATHNG AND CUTTNG PAPER WEBS Laddie Karlik, 410 E. 163rd St., Bronx, NSY. Filed Dec. 13, 1951, Ser. No. 160,406 1 Claim. (Cl. 118-43) The invention relates to a device for storing, dispensing and cutting webs of paper, such as toilet paper, and it is more particularly concerned with a device of the character indicated which includes means for applying a coating to toilet paper webs as it is dispensed.

The invention relates to a coating device for applying a pasty deposit of active chemicals onto the paper from a solid carrier medium composition having said active chemicals uniformly dispersed therein and preformed into a block to medicate and perfume the paper, said composition being the subject matter of my copending Iapplication Serial No. 160,404, and said medicated and perfumed paper product being the subject matter of my copending application Serial No. 250,012.

For the furtherance of physiological, prophylactic, therapeutic and deodon'zing effects it is desirable to provide paper which is medicated and perfumed. It is not generally feasible, however, to impart these properties to the paper, particularly toilet paper, at the time it is manufactured.

In accordance with the invention, there is provided a coating device which comprises a support frame including a housing; means mounted in said housing to support a roll of material to be coated; a cylindrical element axially in vparallel with said roll and mounted on a shaft within the housing; an end of said shaft extending through a wall of the housing for connection with drive means to effect rotation of the cylindrical element; a block of coating material disposed within the housing, free to ride in a horizontal plane passing through the axis of said shaft and bearing uniformly against an axial extent ofthe cylindrical element; a pusher and support plate carrying said block of coating material; means to bias said plate toward said cylindrical element to effect contact between the block and a web of material fed from said roll and passing between said block and cylindrical element; said cylindrical element having an abrasive outer surface to establish a frictional contact between the passing web and the block to effect the coating operation; a plate depending from the housing bottom; a slot extending transversely of said depending plate; the lower edge of said slot defining a cutting edge substantially parallel to said cylindrical element; a pair of spaced strip spring elements each attached at one end, and depending therefrom, at a respective end portion of said dispensing plate; a stretching cylinder mounted between the outer ends of the strip spring elements, disposed horizontally below said cutting edge, and in operative alignment to receive therebeneath and guide therearound said passing web for immediate travel through said slot; the spacing elements being so formed that an extent of `said web passed through the slot and subsequently pulled downwardly will ex said spacing elements to thereby carry the stretching cylinder against the cutting edge and thus serves to clamp the web at said edge to facilitate severing thereof.

The invention will be more particularly described by reference to the accompanying drawing, wherein FIG. l is a vertical sectional view taken along line 1 1 of FIG. 2;

FIG. 2 is a vertical sectional View taken along line 2 2 of FIG. 1;

FIG. 3 is a horizontal `sectional view taken along line 3 3 of FIG. 1;

FIG. 4 is a partial sectional view taken along line 4 4 of FIG. 3;

ICC

FIG. 5 is an elongated cross-sectional front view of the cutting means;

FIG. 6 is an enlarged cross-sectional view taken along line 6 6 of FIG. 3; and

FIG. 7 is another arrangement of the strip spring elements extending from the housing bottom straight downwardly. y

Referring to the drawing, in a housing 1 provided with a door 2, a lock 3 and a hinge 4, and suitably installed on a wall support 5, there is disposed a roll of material 6, to be coated, carried on a shaft 7 provided with a spring 8 for locking shaft 7, with the shaft bearing support 9.

The block 10 of the coating material is disposed on a support plate 12 and pushed forward by a pusher kplate 13 which is guided by connecting pins 14 and a pusher plate guideway piece 15, slidably movable in a guideway rabbet 16.

Means is provided to bias the pusher plate 13 toward the cylindrical element 24 by connecting each pin 14 with a cord 18 which passes over a pulley 19 to a spring 17, the other end of said spring being connected to an equalizer screw 20 which can 'be screwed inwardly and out wardly with respect to the supporting rod 21 for the purpose of lregulating the length and thereby the strength of the `spring 17, so that the block 10 of the coating material is free to ride in a horizontal plane passing through the axis of the shaft 25 and bearing uniformly against an axial extent of the cylindrical element 24.

The cylindrical element 24 is arranged on a shaft 25 extending through a wall of the housing 1 and exteriorly having a handle 26 as drive means to effect rotation of the cylindrical element, said cylindrical element having an abrasive outer surface 24a to establish a frictional contact between the passing web and the block to effect the coating operation.

For the abrasive outer surface 24a of the cylinder element there can be supplemented or substituted a paper of a coarse-grained rippled surface which is used to easily abrade and evenly spread the material from the block onto the surface carrier for providing'a pasty deposit within and upon the cavities of said paper.

The block 10 of the coating material has a soft body for providing layers of a pasty deposit onto the web in an exact predetermined quantity according to the strength of the applied pressure, and can be of a desired width to vlimit the coating application to the middle portion of the web material.

For cutting the strip of material being unwound from the roll 6, the coating device is provided with cutting means which consists of a plate 27, formed either as a continuing extension of the paper guide 23 as shown in FIGURE 4, or as a separate plate attached to the housing bottom as shown in FIGURE 7, and depending downwardly near the housing bottom withdrawal slot Where it is provided with a slot 27a, extending transversely of said depending plate, the lower edge of said plate slot defining a cutting edge substantially parallel to the cylindrical element 24; a pair of spaced U-shaped strip spring elements 28 are attached at the lower outer ends of the plate 27, and extending upwardly as shown in FIGURES 4 and 5; or a pair of straight strip spring elements 28 are attached with :the plate 27 to the bottom of the housing and depending downwardly as shown in FIGURE 7, the outer ends of said strip spring elements being provided with a stretching cylinder 29, `disposed horizontally below said cutting edge, and in operative alignment to receive therebeneath and guide therearound the passing web of the material for immediate travel through the depending plate slot 27a, the spacing elements being so formed that an extent of the web material passed through the slot and subsequently pulled downwardly will ex said spacing elements 28, 29, to thereby carry the stretching Patented Aug. 10, 1965' cylinder 29 against the cutting edge and thus to clamp the web at said edge to facilitate severing thereof.

The substantial improvement of this new cutting appliance resides in the upwardly extending cutting edge disposed and protected ,in the slot of the depending plate to prevent injury Vand to perform the severing more easily, safely, conveniently and accurately while the web is pressed tightly on both sides of the plate against the cutting edge when a downward movement of the web with the hand is applied. v

When the device is used, the leading end of the material from the roll 6 is passed through the paper guide 22 and 23, between the block 10 and the cylindrical element 24, and then through the slot in the bottom of the housing 1 where it can be grasped with the left hand and drawn out for the desired length while at the same time the handle 26 is turned with the right hand to rotate and abrade with the'axial extent of the abrasive outer surface of the cylinder element the web against the block 10 of the coating material to thereby unroll, rub, polish, bland, gsanitize, medicate, scent and dispense said web outside of the housing where it can be cut off.

It will be understood that the device can be used without or with another cutting appliance than as specically indicated, and that the invention contemplates, within its scope, devices which may vary from the specitic example hereinbefore described and illustrated, with the intention of embracing all structure falling within the scope of the appended claim.

What I claim and desire to be secured by Letters Patent is:

A coating device comprising a support frame including a housing; means mounted in said housing to support a roll of material to be coated; a cylindrical element in parallel with said roll and mounted on a shaft within the housing; an end of said shaft extending through a wall? of the housing for connection with drive means to effect rotation of the cylindrical element; a block of coating material disposed within the housing, free to ride in a horizontal plane passing through the axis of said shaft and bearing uniformly against an axial extent of the cylindrical element; a pusher and support plate carrying said block of coating material; means to bias said plate towards said cylindrical element to eiect contact between the block and a web of material fed off said roll and passing between said block and cylindrical element; said cylindrical element having an abrasive outer surface to establish a frictional contact between the passing web and the block to eiiect the coating operation; a slot extending transversely of said depending plate; the lower edge of said slot defining a cutting edge substantially parallel to said cylindrical element; a pair of U- shaped strip spring elements each attached at one end, and depending therefrom, at a respective end portion of said depending plate; a stretching cylinder mounted between the other ends oi said spring elements, disposed horizontally below said cutting edge, and in operative alignmer to receive therebeneath and guide therearound said passing web for immediate travel through said slot;

Vsaid spacing elements being so formed that an extent of said web passed through .the slot and subsequently pulled downwardly wiil iiex said U-shaped spacing elements to thereby carry the stretching cylinder against the cutting edge and thus serves to clamp the web at said edge to facilitate severing thereof.
