This invention relates to a machine for marking successive outlines of a design ona flexible sheet of material, such as cloth, paper and the like. In the production of bedspreads or other like materials, it is necessary to rst mark a plain sheet of material with an outline-so that in subsequent operations, an ornamental design can be placed on the marked outline. After the design has been placed on the outline by any suitable means such as a tufting machine, the article is washed thereby removing the marks.

It is, therefore, an object of this invention to provide a machine which is capable ofreproducing in rapid succession, the outline of a pattern upon a sheet of material. One form of the invention comprises a pattern roll and an adjacent marking roll, between which the material to be outlined is passed. At the point where the markingr roll contacts the cloth, the direction of travel of the cloth is in an opposite direction, to the direction of travel of the marking roll, thereby producing a rubbing action at this point to insure that the material will be properly marked.

1t is another object of this invention to produce a marking machine comprising a pattern roll and an adjacent constantly driven marking roll between which a fabric or other material is adapted to be drawn, with means for yieldingly holding the roll and the fabric-in contact with the pattern.

Also means are provided for reciprocating the marking roil axially during the markingoperation so that an even wear of the marking material will occur.

It is a further object of this invention to provide an apparatus of the class described having an appliance for lifting the material to be marked and the marking roll out of engagement with the pattern and the pattern roll. In the manufacture of bedspreads, it is undesirable to have a seam intermediate the ends of the spread. Therefore, when a seam occurs in the material to be marked, it is necessary to stop the machine and then reposition the pattern and the pattern roli so that a design will begin at the seam. To reposition the pattern roll, the pressure exerted thereon by the marking roll and material to be marked must be relieved. *t

It is a further object of this invention to .-provide a marking apparatus comprising a liked marking roll and a iiXed pattern roll having a pattern therearound, between which a sheet of material to be marked is passed, the pattern roll being covered with a resilient :material of padding, such as sponge rubber to act as a .-base for the pattern. This padding will'enablethe pattern to give way to any irregularity inthe marking-roll and insure relatively uniform pressure; .In this form of the invention an axial reciprocation is also provided for the marking roll.

It is a still further object of this invention to provide a marking apparatus comprising a pattern roll having a pattern therearound, `over which flexible material passes to be marked, and a dye applicator roll normally contacting said pattern before it moves beneath the material. By thus positioning the various parts, the dye will be transferred from the applicator roll to the pattern, and thence from the pattern to the material to be marked. it is usually desirable touse a fugitive -dye in this form yof the invention so that when the finished fabric is washed the outline will disappear.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which-V Figure l is a plan view of my marking apparatus;

Referring morevspecically to the drawings,

the 'numerals it and H denote the side frames for my improved" cloth marking machine which have mounted thereon bearings i2 and ifi in which is journaled a shaft i5. The intermediate portion of shaft l5 supports a patternl cylinder iii, said pattern cylinderhaving a longitudinal groove il therein, for. the reception of the ends of a suitable pattern i8. kFigures 2 and 3 show the pattern i3 fixed inthe groove Il; whereas Figure 4 shows the pattern removed.

i By referring to Figures 4 and 8 it is seen that the pattern I8 has aplurality offraised designs I9 on the topside thereof, and at eac-h end a slide fastener' Eil is provided. When the pattern is placed around the cylinder i6 the two slide fasteners l 2li are' interlocloed with each other bya suitable .slide locking Vmember 2 2 in the manner shown in Figure 4. After locking the ends of the pattern, the interlocked portion is inserted within the groove I1 and then a bar 23 is inserted on top of the interlocked portion to firmly hold the pattern in position on the cylinder I6. When the pattern is installed on the cylinder the raised projections I9 are disposed on the outer periphery.

A suitable lap pin 26 has a roll of material 21 such as cloth or the like wound therearound. The ends of the lap pin are mounted in suitable forked

bearings

23 and 29, said bearings having their lower ends rotatably mounted in cantilevered supports 38 and 3l, respectively. These supports are carried by vertically disposed

shafts

32 and 33 which are rotatably mounted in

bearings

34 and 35, secured to side supports I0 and II, respectively.

The vertically disposed shaft 33 has a laterally extending arm 31 to which is pivotally secured one end of a rod 38, the other end of said rod being pivotally secured to the lower end of a hand lever 39. The intermediate portion of lever 39 is pivoted as at 40 to a rack 4I, said rack being engaged by projecting dog 42 which is normally pressed into engagement with the teeth in this rack by means of a suitable compression spring 43. A vertically disposed link 44 and pivoted lever 45 are employed for raising the dog 42 out of engagement with the rack when it is desired to rotate the lever 39 about its pivot point 40. It is seen by observing Figures l and 2 that when the lever 39 is rotated, that the cantilevered supports 30 and 3I together with the beam 21 will be shifted laterally of the machine. This is necessary to aline the sheet material with the ldrum I6.

A layer of sheet material 48 is drawn from` the beam 21 upwardly over a spreader roll 49 and then downwardly beneath another roller 50. After leaving the roller 50 the material 48 contacts the outer periphery of the pattern I8 on cylinder I6 for a substantial distance. The rollers 49 and 50 are mounted between side frames I8 and ll.

The spreader roller 49 has left-hand threads 49a on the far end and right-hand threads 49h on the near side (Figure 1). The normal direction of rotation of the roller 49 is clockwise in Figure 2, therefore, at the point the material 48 contacts the roller 49, the direction of travel of the roller will be opposite to that of the direction of travel of the cloth. These opposed directions will produce a spreading action to keep all portions of the sheet material taut. In order to produce this counter rotation of the spreader roll 49, a suitable pulley 55 is provided on one end thereof upon which a belt 56 is mounted. This belt is also mounted upon a pulley 51, which is secured to the end of a shaft 58. The shaft 58 is rotatably mounted in` the side frames I0 and I I and has a roller 59 mounted on the intermediate portions thereof (see Figure 3) beneath which the cloth or other material 48 passes after leaving the pattern I8 on the `cylinder I6.

' This roller 49 is positively driven by a suitable gear 68 on the end of shaft 58 (see Figure 2), which gear meshes with a pinion 6I on a shaft 32, said shaft 62 being rotatably mounted be- Shaft 62 also has a pulley 64 Xedly secured thereon upon which a belt is mounted. This belt is connected to a suitable source of power, not shown, for operating the cloth marking machine. It can be seen that since the shaft 58 rotates in a clockwise manner in Figures 2 and 3, that a simlilar direction of rotation will be imparted to the pulleys 55 and 51, and the spreader roller 49 to cause the sheet material tobe 'spread laterally of its line of travel.

The gear 60 (Figure 2) also meshes with an idler intermediate pinion 66, and this pinion,

. inturn, meshes with a gear 61 on the end of a transversely disposed shaft 68. The shaft 68 is rotatably mounted in the side frames Ill and I I and has xedly secured on the intermediate portion thereof, a roller 69. 'Ihe rollers 59 and 69 (see Figure 3) support a take-up roll of material 10 which is formed from the layer of material 48 after it passes over the pattern cylinder.

Both'the rollers

59 and 69 rotate in a clockwise direction, but due to the fact that the gear 61 (Figure 2) has a few less teeth therein than the gear 60 the rate of rotation of the roller 69 is slightly greater than the rate of rotation of the roller 59; consequently, there will be a tendency While the take-up roll 19 is being formed for this roll to gradually become more compact.

Between the rollers 5u and 59, the sheet material 48 is adapted to contact the pattern I8 on the cylinder I6. At a point Where the material contacts the pattern, it is` desirable to place a suitable marking roller, such as indicated by reference character 15, which is mounted around transversely disposed shaft 16. shaft is rotatably mounted in bearings 11 and 18 which are slidably mounted in slides 19 and 8D on sidewall members I8 and II, respectively. Secured to each of the bearings 11 and 18 is a cord vS2, said cord being adapted to pass over a roller 83 and thence downwardly. On the lower end of each cord is a suitable weight 84 which normally maintains tension in the cord 82 and serves to hold the marking roller 15 against the portion of cloth 48 which is disposed around the pattern cylinder. In other words, the weights 84 resiliently and yieldingly hold the marking roller 15 in contact with the cloth and the pattern on the pattern cylinder.

The shaft 16, which supports the marking roller 15, has a sprocket 86 xedly secured on one end thereof (see Figures 1 and 2). Upon this sprocket is mounted a chain 81 which is also mounted upon a second sprocket 88 on shaft 62.

The intermediate portion of chain 81 is contacted by a suitable tightener pulley 89, said pulley being pivoted as at 90 on the side frame II. As the shaft 62 and pulley 64 rotate in a counterclockwise manner in Figure 2, a similar rotation will be imparted to the marking roll 15, at the point of contact with the pattern cylinder and the material to be marked, is in an opposite direction to the direction of travel of the material 48, and the pattern cylinder; consequently, a rubbing action will be effected.

In order to insure that all portions of the periphery of marking roll 15 will wear uniformly, a suitable means for axially reciprocating marking roller 15 and its shaft has been provided. This reciprocating means comprises a suitable cam 92 having a meandering serpentine groove 93 therein which is fixedly secured around the shaft 16. groove 93 and this pin is'supported by the bracket 18. It is seen that as the marking roll 15 rotates that the pin 94 which remains in a fixed position will cause the cam to reciprocate toward and away from theobserver a slight amount thereby causing the marking roller to move axially as it rotates and more evenly distribute the Wear on This a A stationary pin 94 is adapted to iit in mixed with coloring pigment.

the marking material. The marking material may be composed of any suitable material-such as a chalk-like f ormatiomor it. may be composed of an oleaginous. material such necessary to discard the marked bedspread which includes the seam or it is necessary to stop the machine and reposition the` pattern cylinder so that the pattern will begin at the seam. The latter method will eliminate waste of at least ay portion of a bedspread.

When it is desired to reposition the pattern and the pattern cylinder, it is necessary to release the frictional contact of the marking roller I5 and the sheet, material 48.` In order to do this, a

-pair of spider members |08 and ||l| have been rotatably mounted around shaft I5. These spider members. have arc rims` ||l2 and |03 respectively integral therewith, said arc portionsbeing on a slightly greater radius from the axis \|.5 than the periphery of the pattern cylinder. Between the arc members |02 and |03, suitable transversely disposed rods |84 are secured which are adapted to move in close proximity to the periphery of the pattern I8 on the pattern cylinvder I6. When in normal position the spider members are as shown in Figure 2; whereas when in an operative position, so that the cloth or sheet material 48 Will` be raised from the periphery of the pattern cylinder, the spiders are in the. position shown in Figure 3. The arc member |02 and |03 have secured thereto as at |06 .and IU'I, suitable cords |08 and |09. The other ends of these cords extend upwardly and are secured to pulleys Im and respectively, said pulleys, in turn, being secured to a transversely disposed shaft ||2. The ends of the shaft ||2 are rotatably mounted in bearings |I4 and H5. The bearing E I5 (Figure 2) has a pivoted dog I I6, the free end of which is adapted to engage ratchet I I'I, which ratchet forms an integral part of pulley Upon one end of the shaft ||2 a crank |I8 is placed, which is used for Winding the cords` |08 and |09 around the pulleys I lll and III to thereby cause the spider members |08 and I0! to movev .f from the position shown in Figure 2 to the position shown in Figure 3, at which'time the material 48 will lbe removed from binding contact with.

the periphery of the pattern roll IB.

It will also be noted that the arc members |[l2'y move this roller away from the pattern roller at the same time the sheet material`48 is being removed therefrom. The ratchet I II and pawl f H6 serve to hold the spider members in raised posi- Y tion, but when it is desired. to return the members 'to lowermost normal. position the ratchet H5 is rel-eased thereby allowing the shaft ||2 to rotate in a clockwise manner and release the spider members. When the spider membersv are in raised uppermost position, as shown in .Figure 3, the

'cylinder I6, may. be-.repositioned by a partial roas .paraffin I8 as designated by the. slide fasteners 2li and 22 and slot'I'I, will coincide with the seam. This repositioning is effected by means of a suitable hand wheel |20 which is iixedly secured on the end of pattern cylinder shaft I6. Figures 5 and 6 showa slightly modified form ofv the invention in which like reference characters. will applytolike partsand a description will be made only of theparts and arrangements which differ from those of the preceding form. In this form, the side frames I and H have suitable-slides |39 and |3| mounted thereon, in which is `adjustably mounted bearings |32 and S33, respectively. Journaled in these bearings arethe ends of shaft I6 which carries the marking material l5. The bearing |32 has a cap plate 34 secured to one side thereof (see `Figure 6), which plate rotatably confines the righthand end of a threaded rod |35 against the bearing. This rod has its intermediate portion threadably secured in upstanding projection |36 of the slide |3|J and a suitable hand wheel |3'I is provided on the extreme left-hand end thereof for turning the rodA |35 and thereby adjusting the position of bearing |32 and its associated parts relative'tc the stationary slide |39. Likewise the slide IBI hasI asimilar upstanding projection |38, and this projection has threadably mounted therein the intermediate portion of rod |39, said rod having a hand wheel |40 on its left hand end and having its right hand end rotatably secured to one side of the bearing |33 by means of a plate |4I. This plate |4| extends inwardly toward the marking roll and has a pin |42 extending laterally therefrom whichl penetrates a suitable serpentine groove |43 in a cam |44 which cam is xedlysecured. around the shaft l5. As the marking roller I5 rotates the stationary pin |42 will cause the cam |44 and its associated roller I5 and shaft l to move axially back and forth, and produce an even wear on the periphery of the'marking roller as it engages the sheet material 48 and the pattern on the cylinder I5. It is. therefore seen that the marking roll remains in a stationary position so far as movement toward and awayfrom the pattern cylinder is concerned.

The pattern cylinder I6 differs from that of the preceding form in that its periphery has a resilient padding such as sponge rubber |48 secured thereto and over this sponge rubber the pattern I8 is adapted to fit. The sponge rubber affords the necessary resiliency between the two cylinders to account forl any irregularities in either member. When the marking roller I5 has worn a substantial amount, i-t is only necessary to adjust the rods |35 and |39 to move the marking roll into closer engagementwith the pattern on the pattern cylinder.`

Figure 7 shows another modified form of the` invention in which a liquid dye is applied to the pattern I8 directly andthe pattern, in turn, appliesthe dye solution-to the material 4S. In this formofthe invention, the pattern cylinder IS is rotatably mounted between two side frame members |50 as well as members 49, 5|), 59, t2 Disposed beneath the pattern cylinder Il6 is a rubber covered applicator roller itl., the ends Vof which are rotatably mounted in suitable bars such as |52. These bars are penetrated by upstanding dowel pins |53 which are anchored in a trough |54. 'In order to resiliently hold the roller |5I. in contact with the cylinder |51, suitdowelpins |53,y between theupper side of the Git trough tt and-the lower side ofthe bar I 52. Disposed in this troughis a solution such as a fugitive dye |56 and this dye solution has the lower portion `of the applicator roll |5| submerged therein. As the pattern cylinder I6 is rotated in a counter-clockwise manner in Figure '7 the frictional contact of the sheet material 48 on the periphery of the pattern I8 will drive applicator roller |53 to cause it to gather dye solution 15B from the trough and apply it to the projections I9 on the pattern after which these projections I9 will transfer the solution to the material 4B to print the same. In this form of the invention, it is preferable that the background of the pattern be made of non-absorbent material and the raised portions I9 be made of absorbent material so that only the raised portions will transfer dye tothe fabric.

' Both of the modified forms shown in Figures 5, 6, and 7 may have the means shown in the preceding form for removing the sheet tobe marked from contact with the pattern roll fo-r positioningr the pattern roll.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used" in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims. 1
