HENRY I. ROSENBLUM, OF NEW YORK, N. Y.

MACHINE FOR LAYING- FABRICS.

Application filed September 18, 1918. .Serial No. 254,597.

To all whom it may concern:

Be it known that I, HENRY I. RosENBLUM, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Laying Fabrics, 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.

This invention relates to apparatus used in the manufacture of garments of various kinds and classes and particularly for use in the laying of fabrics in piles on a table prior to placing the patterns on said piles and cutting garments or parts of garments therefrom, and the object of the invention is to provide an apparatus of the class and for the purpose specified which involves a machine movable longitudinally of the table and which is designed to lay cloth or sheets of cloth of any width in piles of any desired length to be operated upon as above set out; a further object being to provide a machine of the class specified which is designed to lay either one or more sheets or plies of fabric on the table in a single operation or at each movement thereof over the table; a still further object being to provide means for automatically recording the number of sheets or plies of cloth in a pile; and with these and other objects in view the invention consists in an apparatus of the class and for the purpose specified, constructed and operating as hereinafter described and which is simple in construction and operation and efiicient in use.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which I Figure 1 is a side View of a table partly broken away and ShOWIDg my improvement in connection therewith;

Fig. 21 an enlarged detail view of one of the folding members which I employ and shown in the same position as illustrated in Fig. a of the drawing; and,

Fig. 22 a sectional view on the line 22-22 of Fig. 21.

In the practice of my invention I provide a table 20 upon which the cloth is to be laid, said table being of predetermined length and width and at the front side thereof is a board 21 secured to the table 20 by brackets 22 and between the board 21 and corresponding edge of the table 20 is a space 23, as clearly shown in Fig. 3 of the drawing.

My fabric laying machine 24 is mounted to move longitudinally of the table 20 and board 21, or on a rail 25 on the top face of said board, and in the construction thereof I provide two pair of vertical standards 26 at the front and back of the machine, each of said pair being connected at the top by a cross head 27, approximately centrally thereof by a cross member 28 and adjacent to the lower ends thereof by another cross member 29, and each of these constructions constitute front and back frame members 30 and 31 respectively, which are connected at the top by forwardly and backwardly directed rods 32 coupled with the top cross head 27 as shown at 33, and also connected adjacent to the bottom thereof by forwardly and backwardly directed rods 34 coupled with the standards 26 as shown at 35, and the forwardly and backwardly directed rods 34 are joined adjacent to the front and rear ends thereof and inwardly of the frames 30 and 31 by cross rods 36.

The top cross head members 27 of the frames 30 and 31 are extended at the left and right as shown at 37, and the end portions thereof are connected by cross rods 38 upon which are mounted gage devices 39, which serve to guide the fabric as it passes over the rods 38, as hereinafter described. The cross members 29 at the base of the frames 30 and 31 are also extended as shown at 40 and the end portions thereof are each connected by a pair of forwardly and backwardly directed guide rods 41 as clearly shown in Figs. 2 and 12 and between which the material passes as hereinafter described, and the front cross member 29 is provided at its ends with forwardly directed hand pieces 42, whereby the machine may be moved longitudinally of the table 20 and rail 25.

The above described construction constitutes the main skeleton or framework of the machine and, in practice, I adjustably secure to the lower end portions of the vertical members 26 of the frames 30 and 31, depending roller supports 43, and grooved rollers 44 are rotatably mounted in the supportsof the front frame 30, while plain rollers 45 are rotatably mounted in the supports of the back frame 31, as clearly illustrated in Fig. 3, and by means of these rollers, the machine may be freely moved longitudinally ofthe table 20 and guided in this movement by the engagement of the grooved rollers 44 with the rail 25.

Mounted upon the forwardly and backwardly directed rods 34 is a main bottom platform or table 46 ugon which the fabric to be laid upon the table 20 is placed, as illustrated at 47 in Fig. 12. A supplemental top table orplatform 48 is mounted upon the forwardly and backwardly directed rods 32 joining the top cross head 27 and upon which other fabric 49 may be placed.

Secured approximately, centrally of the cross rods 36 which join the rods 34 are blocks 50 in which are mounted vertically movable racks 51 at the bottoms of which are cross heads 52 connected by two rollers 53 and a central cross rod 54. A forwardly and backwardly directed shaft 55 passes through each of the blocks 50 and the front end thereof extends beyond the front frame 30 and is provided with a hand-piece 56. Secured to said shaft within the blocks 50 are gear wheels 57 which cooperate with the racks 51 to move the same vertically in the blocks 50 when the shaft 55 is rotated. Pawls 58 are pivoted to the top of the blocks 50 as shown at 59 and cotiperate with the gear wheels'57 to hold them in any desired position.

The above described rack construction constitutes a vertically movable guide member 60 through which the fabric passes in the operation of laying it upon the. table 20, and by means of which the fabric is laid smoothly upon the table and also stretched or drawn taut, and as the sheets or plies of fabric increase, said guide member is moved vertically so that the rollers 53 rest upon or have a slight clearance with the top sheet or ply.

I also preferably employ four shoe members 61, one of which is shown in detail in Fig. 10, and the operation of two of which is shown in Figs. 17 to 20 inclusive, and each of which consists of a downwardly curved head portion 62 having an aperture 63, with offset portions 64 and 65 therein, and said shoes are provided with arms 66 having an elongated slot 67. The arms 66 are adapted to be adjustably connected with the roller supports 43 or to brackets 68 secured at the opposite sides thereof. The connection of the shoes 61 with the roller supports 43 is such that said shoes will extend outwardly from the right and left hand sides of the frame, as clearly shown in Figs. 1 and 2 to form two pair of shoe members 69 and 70, the pair '69 being at the right of the machine while the pair 70 is at the left thereof, and it will be noted that the right hand pair are set a predetermined distance lower than the left hand pair, as clearly illustrated in Fig. 1.

Two supplemental frame members 71 and 72 are connected with the table 20 in the manner shown in Fig. 16, and these frames each consist of front cross plates 73 to the top faces of which are adjustably connected strips 74, having central block portions 75 to which are secured forwardly and backwardly directed angle irons 76 secured to similar blocks 77 on strips 78 adjustably mounted on rectangular fiat plates 79, which Figs. 17 to 20 are placed upon the table20. Said frames, as above described, are preferably secured to the table 20 at predetermined points and theframe 71 remains permanently in one position, while the frame 72 is adjustable toward and from the same, but it will be understood that the frame 71 may also be adjustable, and said frames are also preferably reinforced by stay wires 80 connected with the end portions of the front cross plates 73 at 81 and tothe angle'irons 76 as shown at 82, and turnbuckles '83 are mounted in said wires whereby the tension thereof may be regulated.

The above described construction pertaining to each of the frames 71 and 72 is common and in the construction shown in Figs. 1 to 13 and 16 to 22 inclusive, the blocks 75 and 77 of each of said frames are provided centrally with vertical rods 84, and mounted on said rods are vertically movable guide and folding members 85 at the top of which are adjustably connected horizontal plates 86, having downwardly directed pins 87 in one corner portionthereof, which pins are adapted to cooperate in the recesses 63 of the shoes 61 and the offset portions 64 and thereof, when-said shoes strike the bottom'faces of the plates 86 and raise the members 85 on the. rods 84. h

The members 85 are provided in one face thereof with a plurality of vertically arranged holes 88 and with which are ad'- justably connected fingers 89 around which the fabric laid'upon the'table is adapted to pass, and which form the folding members for said fabric when in their normal position, as shown in F gs. 17 and 19 and at the right of'Fig. 1 6 but saidfingers-are moved outwardly into the position shown in Figs. 1, 2, 4, 18 and 20 and at the left of Fig. 16 by the shoes 61 operating upon the plates 86 and pins 87 thereof, which-operation raises the members 85 and rotates them' one-quarter revolution, as illustrated in inclusive and as hereinafter described. V

The guide and folding members 85 of the frame 71 are shorter than the corresponding members of the frame 72 and the pair of shoe members 69 are adapted to cooperate with the guide members 85 of the frame 71 while the pair of shoe members cooperate with the guide members 85 of the frame 72,

and when said guide members 85 are in their depressed or operative position, lugs 90 on the bottom portion-thereof coiiperate with a pair of upwardly directed lugs 91 oneach of the blocks and 77 to hold said members from rotation, and one of said lugs 91 on each of said blocks is beveled as shown at 92 to permit of the passage of the 90 thereover, while :the members 85 are raised and rotated.

Secured to the opposite ends of the angle Secured to one end portion of the plate 73. vof the frame 72 is a bracket 96 to the ,7

top of which is secured an'upwardly inclined finger piece 97 which is adaptedto cooperate with a registering mechanism 98 secured to the front frame 30 of the machine, and by means of which the number of plies or sheets laid upon the table may be, auto matically recorded.

llhe registering mechanism 98 consists of 2a cup-shaped annular casing 99 within which is mounted an annular wheel 100 rotatably mounted on a shaft 101, having a bearing in a cross member 102 secured to the back face of the casing 99 as shown at103 in Fig. 6, and one side. edge of the wheel 100 is provided with a plurality of teeth or projections 104 in connection with which a finger 105 operates, said finger; passing through a slot or aperture 106in the wall ofthe casing 99, as shown in Fig. 6 6 ofthe drawing. 7

The casing 99 is adjustably supported on the bottom cross rod 29 of the front frame 30 by means of a plurality of 'sleeves107,

and a plurality of tensional devices 10 8 are mounted within the casing 99 and cooperate A with the front face of the wheel to hold thesame against accidental rotation, said 'tensional; devices being controlled by adjusting screws 109. The'periphery of the wheel 100 is provided inwardly of the teeth or-projections thereof with a scale 110, as illustrated in Fig. 6, the numerals ofwhich correspond with the number'of teeth or prov jections on said wheel, and as the wheel is advanced by the 'fi-nger 105, the recording of this operationmay be noted through an aperture 111 in'the casing 99.

The finger 105 is operatedthrough the lever 112 pivoted'to the front frame 30 at' 113. V Pivoted to one end of the lever at 114 is a vertically movable yoke 115, consisting of'front and back plates 116 and 117 connectedat the top and bottom by pins 118 fand 119. The yoke 115 is guided bythe cross members 28 and' 29', as clearly shownin Figs. 5 and 6.

Inthe operationof the machine over'the 7 table 20 andwhen the same reaches the right hand end of said table, the finger 97' will strike the pin 119 ofthe yoke 115 and depress the same, which operation will also 100 a fraction of a revolution to record 'on the scale 110 the number of plies'or sheets depress the finger 105 and'rotate the'wheel I laid upon the'table and, in practice, I"preferably connect the finger 105 and lever 112 by a spring 120, which normally holds the finger in proper position. The lever 112, or the free end thereof is provided with a spring 121 which is connected with the frame 30 as shown at 122 and serves to hold the yoke 115 in its proper position.

The roller supports 43 of each frame 3031 are preferably connected by cross rods 123, said rod of the frame 30 being bent outwardly and downwardly to-a slight. extent as shown at 124, which aids in guiding the yoke 115 in its vertical movement.

The cross members 28 and 29 of each of the frames 3031 are connected approximately, centrally thereof, by vertical rods 125 which extend above the cross rods 28 and to the top of which are secured arcshaped bearing seats 126, and a forwardly and backwardly directed shaft 127 mounted in the bearing seats 126, or bearing'members 128 on said shaft are placed in said seats. Secured to the shaft 127 inwardly of the ends thereof are blocks 129 carrying or supporting triangular-shaped bodies 130, which are adapted to pass into and support what are known as bolts of fabric, as indicated in dotted lines at 131 in Fig. 3, and said construction involving the shaft 127, blocks 129 and triangular bodies 130 form a rotary support for said bolts, whereby the fabric thereof may be unwound and laid upon the table 20 as hereinafter described.

In Figs. 14 and 15 of the drawing, I have shown a slight modification of that shown in Figs. 1 to 13 inclusive, which consists in removing the members 85 from the rods 84 and securing supplemental rods 132 in holes 133 in the blocks 75 and 77 to form two vertical standards at the opposite sides of each of the supplemental frames 71 and 72 be tween each. of which are adapted to be placed two cross rods 134, the front ends of which are provided with hand-pieces 135 bent at right angles thereto. The object of the construction shown in Figs. 14 and 15 is to provide hand-operated means for producing the fold in the fabric in the operation of laying the same upon the table 20,

which is automatically produced by the fingers 89 on the members 85 in the construction shown in Figs. 1 to 13 and 16 to 22 inclusive.

The operation of the machine, as shown in Figs. 1 to 13 and 16'to 22 inclusive, will be readily understood from the foregoing description whentaken in connection with the accompanying drawings and the following statement. In laying a single ply or sheet of material upon the table 20, the same being taken from a pack such as that shown at 47 in Fig. 12, or from a bolt indi-' cated in dotted. lines in Fig. 3, the end portion thereof is threaded through the machine by first passing it over one of the rods quarter revolution, which moves the fingers 89 thereof outwardly into the position shown in Fig. 2 and at'the left of Fig. 16, after which the machine is moved to the right, in which operation the members 85 at the left of the table drop by gravity and the fingers 89 thereof move inwardly as shown in Fig. 17, and the cloth or fabric passes thereover to form a fold in said cloth or fabric at the left hand end of the table as shown at 136 in Fig. 12 of'thedrawing. When the machine reaches the extreme right of the table, the shoe members 7 0 will coeperate with the guide andfolding members 85 at said end of the table to raise and rotate the same which operation mgves the fingers 89 of said members 85.from the position shown in .Fig. 19 to'that shownin Fig. 20, and by again moving the machine to the left said guide members will drop gravity and the fingers 89 thereof agaln move inwardly into the position shown in Fig. 19 and at the right of Fig. 16 so as to permitthe cloth or fabric to pass therearound and'thereover to form a fold 137 at the right hand end of the table. In both of the above described operations of the guide and. folding members 85, the pins '87 thereof operate in the offset portions 64 and 65 of the shoe members 69 and 70,:and said offset portions also serve to operate the pins 87 to turn the members 85 and to move the fingers 89 thereof, as above described.

The above described operation is continued until all of 'the fabric in the stack or bolt is exhausted, or until the desired number of plies or sheets are produced in the pile and, as hereinbefore stated, when the machine reaches the extreme right of the table the registering device 98 is operated to record the number of plies laid upon the the fingers 89 thereof from the fold and places it upon the top of thefabric laid by table to raise the same and rotate them onedetails of construction for carrying my inthe advance of the machine over the table. The fingers 89 at the opposite end of the table holds the material in proper position in this operation.

terial by'the-pins 94 asshown at 95, and the operation will be exactly the same as in the laying of a single ply or sheet.

The operation of the construction shown in Figs. 14 and 15 will be exactly the same as that shown in Figs. 1 to 13 and 16 to 22 in-' clusive, except that the automatic folding of the fabric as it is laid upon the table is done away with by removing the guide and folding members 85, and when the machine reaches the extreme left or right of the table 20 one of the cross rods 134 is placed" upon the top of the fabric with the other crossv rod therebeneath, and as the plies or sheets increase the bottom cross rods at each end of the table are withdrawn and placed upon the top of the, fabric thus leaving two cross rods 134 at each end of the table at all times. This last describedmethod of operation is not preferred by reason of the fact that much time is lost in the manipulation of the rods 134, but it will be found necessary to use this method of folding the fabric when thin or silky fabrics are laid upon the table 20. The automatic folding device shown in Figs. 1 to 1'3 and 16 to 22 inclusive is particularly designed for use in connection with strong andheavy fabrics.

Each pair of th'e cross heads '41 are pro-' vid'ed adjacent to the front and rear ends thereof with gage devices 138, which guide the fabric as it passes between said rods and prevents the shifting of said fabric forwardly and backwardly in the operation of laying it upon the table.

While I have'shown and described certain vention into effect, it will'be understood that I am not necessarily limited to such details, as various changes therein and modifica tions thereof may bemade, within the scope of the appended claims, Without departing from the spirit of my invention or .sacrificing its advantages.

It will be understood that asthe plies or sheets of the fabric increase upon the table in the operation of the machine the fingers '89 of the members 85 are raised on said members by properly inserting said fingers Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
