SPECIFICATION forming part of Letters Patent No. '736,59 5, dated August 18, 1903.
Applicatiou'iiled June 8,1901. Serial'No. 63,739. (No model.)
To @ZZ whom, it may concern-a Be it known that LJosEPH ARNOLD GROEBLI,
residing atV New York, in the county of NewV York and State of New York, have invented certain new and useful Improvements in Machines for Making Trimmings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention has for its object to provide an improved apparatus or machine for the manufacture of a trimming which consists of a strip of fabric folded longitudinally and having a characteristic design, as an undulated or fluted outline imparted toits folded edge,and which may have alsoa thread wound spirally around it, the spiral following and conforming to the depressions along the edge.
.The apparatus preferably employed by me for manufacturing the article embodies gen-- erally devices for folding the strip, means for forming or impressing the edge so that it will present the desired outline, means for feeding and ironing or pressing the trimming, and means for winding the tread spirally therearound.
Hy invention consists, further, in certain mechanisms and appliances, as will he hereinafter more fully described and the novel features pointed out in the claims at the end of this specification.
In the accompanying drawings, Figure 1 is a plan View of a machine for making the trimming according to my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a sectional view of the folder and forming-disks on line A B, Fig. 1. Fig. l is a transverse section taken on line C I), Fig. 1. Fig. 5 is a View, on an enlarged scale, of a piece of the finished trim ming.
Similar characters refer to similar parts throughout the several Views.
1 represents the base-plate of the machine, 2 an upright support which has bolted to it the angle-piece 3, to which is connected the folding-guide f1, the shape of which is shown most clearly in Figs. 1 and 3,1 wherein it is represented as having its sides turned over,
as at 5, in order to turn in the rawv edges of the strip of fabric passed through it and toward the middle, as at 6, having bothits sides turned in in order to give a second fold to the fabric in the center thereof, all as will be well understood by any one skilled in the art.
I have shown a folder which givesadouble fold for the purpose of turning in the raw edges and then folding the fabric longitudinally along its center; but the preliminary folding of the edges can be dispensed with, if desired, and where in the claims I use the term folding-guide I intend that term in its broadest acceptation.
Arm 7, projecting from the supportZ, fur- Vnishes an end bearing for the shaft 8, which is driven by worm-wheel 9 and Worm 10 from the main driving-shaft 11, to which power may be supplied by a driving-pulley 12 or by other suitable means and which is supported in bearings on the base, as shown. carries a sleeve which provides a bearing for the other end of the shaft 8. Carried on end of shaft 8 and revolving therewith are two guiding-disks 13 13 and the forming-disk 14, having its periphery shaped,as here shown, by alternate concave portions and comparatively sharp elevated portions to present an outline which may be termed' scalloped or undulated. Key S passes through the disks 13 13 and 14: and through clamping-collars on each side thereof to lock these parts to shaft 8. In a sleeved bearing carried by an arm 15, projecting from the support 2 above arm 7, is supported the spindle 16 of a second forming-disk 17, which spindle is free to revolve in said bearing. Disk 17 has its periphery tinted or shaped with alternate con- Vexl portions and comparatively narrow concave portions, so that it will mate or mesh with disk 14 and be driven by contact therewith. These two disks are located adjacent the end of the folding-guide and lie in avertical plane, which is a plane passing through the center of said folding-guide, and they are thus adapted to act upon the central folded edge of the strip of fabric issuing from said foldingguide. The circular disks 13 13,
which lie close to the lower forming-disk 14:
Bracket 8".
on each side thereof, are of a diameter greater than the disk 14, so that they are adapted to act as guides both for the fabric passing between the forming-disks and for the upper forming-disk to insure its proper position with regard to disk 14. It is obvious that these disks might be made stationary with the forming-disk rotating between instead of having all the parts rotate together. These guiding-disks might be dispensed with altogether, and in their place stationary guideplates might be used to guide the fabric between the forming-disks and to preserve the position of said disks with relation to each other. It is necessary in order that the folded fabric may pass between the upper forming-disk and guiding-disks that there be a free space between such disks. In the present embodiment of my invention, as shown most clearlyin Figs. 3 and 4, I have provided for such free space by making the formingdisk 14 of greater thickness than the formingdisk 17, whereby space is left between the forming-disk 17 and the guidingdisks,which will allow the sides of the folded fabric to pass therebetween. It will be obvious, however, that the same result could be accomplished if the forming-disks were made of equal thickness and the guiding-disks arranged in such a way as to provide for sufficient space on either one or both sides of forming-disk 17. Rolls 18 and 19 are positioned to act as feeding-rolls for the fabric issuing from the forming-disks and likewise act to iron or press such fabric. As most clearly seen in Fig. 4, roll 19 is carried with the stud 20, which has a step bearing upon the upright post 21. The stud 2O is driven to revolve this roll from the shaft 8 by a chain of gears 22, 23, and 24, meshing with the gear 25 upon the stud itself. The bevel-gears 23 and spur-gear 24 are carried by the stud 26, which passesthrough and has a bearing in the cross-piece 27 of a U-shaped bracket rising from the base, the two legs of which areI indicated at 28 28. Collars are interposed between said cross-piece and the respective gears. The roll is mounted on stud 29, which is carried by arm 30, pivoted at 31 to post 32. The rod 33 has one end seated in a lug carried by the bracket 34, (shown in Fig. 2,) bolted to the post 21. This rod 33 passes loosely through thel arm 30, and between a head 35 on said rod and the arm 30 a spiral spring 36 is seated, thereby holding roll 18 normally in contact with roll 19. The pivoted arm and spring holding it, however, allow this roll to be drawn away from its companion roll for insertion of material or at other times, as desired, and likewise prevent injury to the material by furnishing a yielding bearing for one of the rolls. As will be obvious, the head 35 might be made in the form of an adjustable nut in order to adjust the position of the spring andthe amount of friction between the two rolls, of which roll 18 is driven by frictional contact with roll 19, as will be rsa-ses clearly understood and as is illustrated in connection with the same form of device in a further part of this machine. These rolls may of course be geared together, so that both rotate positively. An angle-piece 37, carried by the post 21, supports a guide 38, which presents a narrow longitudinal passage-way, through which the fabric passes after it has issued from between the pressing and ironing rolls. The course of the fabric through the machine is clearly illustrated in Fig. 2, and it will be .understood that the operative parts are alined, so as to be in position to act upon such fabric or trimming as it passes in a straight line from one end of the machine to the other.
Next to the guide 38 is a device for winding a thread spirally about the trimming, said device consisting of a tubular arbor 39, which has its bearing insleeves 40 40, carried by supports 41 41 from the base. This arbor is driven by a gear 42 thereon and intei-mediate gear 43 from gear 44 on the main driving-shaft. This device for winding the thread or rotary twister-head, as it iscom- Inonly called, comprises, further, a disk 45, which carries brackets 46, furnishing supports for the thread-spool 47, from which the thread passes through a guide-or eye 48 in a lug on the back of the disk, through the cenr ter of the hollow arbor, through a second eye in the end of bracket 49, adjustably supported upon the end of the arbor for purposes well known in the art, whence it is carried around the trimming as the twister-head is revolved during the passage of the trimming through lthe machine. A second pair of feeding and ironing rolls 50 51. receive the trimming as it issues from the rotary twister-head and pass it on to any desired point. lower roll 50 has its shaft 52 supported on an arm projecting from an upright 53 and is driven from the main driving-shaft of the machine through worm 54, worm-wheel 55 on shaft 56, gear 58, connecting gear 59v and gear 60 on the end of shaft 52, as is clearly shown in Fig. 1. Roll 51 is revolubly held by spindle 61, which spindle is carried in the end of the arm 62, pivoted at 63 to support 53, and is held yieldingly in contact with the roll 50, from which it is driven by frictional contact or by-gears by means of the spiral spring 64, held between the nuts 65 upon the rod 66 and the arm 62 in a like manner, as has been described in connection with the adjustable roll 18 and as will be readily understood from an inspection of Fig. 2.
In general the operation of my machine is clearfrom the foregoing description. A strip of fabric a is fed into the folder, which is shaped as shown, so that the raw edges are turned in, as shown at b, Figs. 3 and 5, and the entire strip is further given a longitudinal fold along its center. It then passes between the forming-disks, the upper one of which passes down into the center of the fold on the inner side of the edge and the lower IOC Ifo 5 The TIOv
'leases of which coacts therewith on the outer side of the edge to shape the fabric in conformity with the design which has been given to the peripheries of the forming-disks. This action is clearly shown in Fig. 3, wherein the fabric is shown at o as having still astraight edge. At d the operation is shown partially completed, and at e the trimming is completed so far as the characteristic design to be given to its edge is concerned.
For the purposes of this specification it is immaterial whether it is said that the fabric is bent, folded, impressed, or distorted into the desired form. The function of the forming-disks is analogous to that of roller-dies, and such function is clear whatever terms are to be applied thereto.
While I have shown disks the peripheries of which are shaped so as to give the fabrica scalloped edge, it is clearly to be understood that the shape of these disks or rollers may be changed to give any desired shape or configuration to the edge of the fabric. If desired, heat may be applied to the formingdisks and pressing-rolls, whereby the pressing of certain materials will be facilitated and the appearance of the finished article somewhatimproved, although this isin nowise necessary to the successful working of the machine. Suchheatingmaybeaccomplished in any desired manner, or any of the single parts may be heated without heating all the others in a manner well known in the art.
The fabric passes from the forming-disks through the first pair of feeding and ironing rolls which have their axes perpendicular, so that the plane of the trimmingis not changed, then through the guide 3S and the rotary twister-head, by the revolution of which as the trim ming is passing through a thread will be wound spirally around the trimming, following and conforming to the depressions in the edge thereof, as clearly shown in Figs. 2 and 5. The proper ratio between the feeding movement of the trimming and the rotation of the twister-head in `order that the thread may be wound -properly to conform to the outline of the trimming is obtained by proper proportioning and adjusting of the gear 43. Issuing from the twister-head the trimming passes between the second set of feeding and ironing rolls 50 5l.
I have illustrated what I consider the preferable form of my invention; but I do not desire to be strictly limited thereto, as various changes in details may be made without departing from the spirit of my invention.
