INSERTION-STRETGHING MACHINE.
Application filed September 21, 1925.v Serial No. 57,663.
My invention relates to a new'and useful improvement in the method of attaching flexible draw strings in a casing or hem of fabric, and is particularl adaptable for this purpose, where the, flexible draw string is elastic, or resilient, and of,less linear dimension than the hem or casing in which it is to'be inserted.
Where the insertion, which the draw string is termed in this specification? is of less length than the hem,jor casing, in which it is to be inserted, with methods now in use, it is necessary for the 'operatorinserting the insertion in the hem, to move the hem alongthe insertion at intervals, crowd ingthefabrie of the .hem,or easing, into tucks. On account of the binding of the fabric, when crowded into tucks on the insertion, the-operation is a slow and somewhat expensive one, and to avoid the" necessity of moving the fabric along the. inser-H tion, is one of theobjects of the present invention.
In-inserting the'insertion in thenhem or casing, the fabric is generally folded over the insertion, then stitched. This operation is a progressive one'throughout the length of the fabric. It is an object of the present invention, to provide a machine which willv serve to stretch the elastic, or resilient in-..
sertion'to the same'length as the material In inserting elajstie,or resilient insertion lnto a casing, or h ein, the casing, or,.hem,' is generally;uninterrupted, so thatthe elastic,
or resilient insertion is joined togetheifat its ends, when being inserted into thecasingor hem,of'the fabric, or it is joined together at its ends immediatelylafterward. The pres ent invention is particularly adaptable for inserting the insertion in material, which is uninterrupted, although, from the description it will appear that strips of fabric be operated upon bythe method andwith the machinedisclosed 1n the present 1nvention.

The various forms shownin-the different view embody the principles of the invention,
with slight variations and modifipations,
F'g. ,13. is a sectional view] takenion sub- Fig. 15is a fragmentary rear elevational substantially line 15.15 of a v Fig. 17 is a'sectional viewztaken onisuband theseflnodifications have. been shown to illustrate the adaptability ofthe invention 1 to various methods of operation and .to
various kinds of work. If desired, the feeding mechanism may be omitted, and the fabric fed by the hand of the operator assisting the fabric feed of the sewing machine.
The sewing machine illustrated in the, drawings is of the conventional type used for sewing fabrics and embodiesa head 27 I 34 may be mounted, if desired, on the bed 28 for adjusting the tension of the belting 32, as shown in Fig. 11. The bed 28 is supported by suitable uprights and 35 and 36 and 36'. A pedal 37 is connected by suitable rod 38 to the control mechanism of the machine, so that the operator, by moving the pedal 37, may turn the machine on or ofi'.- A pedal 39 is also pivotally mounted and connected by a rod 40 to a braking lever 41, which is designed to reduce the speed of the motor and bring the machine to a sto after the power has been shut off.
I i: the drawings, I have illustrated in Fig.
I -8,.the insertion of a resilient spring 42 in a casing or hem 43, formed in the fabric 44 of a tire cover. Rotatably mounted upon a suitable shaft 45 which is journaled in a bracket 45', which is mounted upon the upper end of the standards 35 and 36, or mounted upon the undersurface of the bed 28,, as desired, is a roller 46 provided, as clearly seen in Fig. 10, with a flange 47, and a peripheral groove 48, the outer face 49 thereof .being beveled adjacent its outer end. In the drawings, I have shown a pair of these rollers, the roller 46 being supported by :suitable bracket 46", and rotatable, although any desired number may be used.
In the form shown in Figs. 1 and 2, I have shown one form of mounting an adjustable stretching wheel. In the form shown in Figs. 1 and 2, this stretching wheel 50 is journaled upon a shaft 51, which is supported by a projection 52, projecting outwardly from the sleeve 53, which is mounted upon the standard A collar 54 is slidably mounted upon this standard 36 and provided with a set screw, whereby the position of the collar 54 may be fixed relatively to the standard 36. By fixing the position of thecollar 54 on the standard 36, the position of the sleeve 53 is also fixed.
Slidably mounted upon the standard 36 is a collar 55, which is provided with a set screw, so that it may be secured in fixed position on the standard 36. Positioned upon the standard 36, in embracing relation the arm 59 is a rod 63, which is between the collar 55 and the upper end of the sleeve 53, is a spiral spring 56, which, when the collar 55 is moved into close relation to the upper end of the sleeve 53, serves to engage the upper end of the sleeve and retain the lower end of the sleeve 53 in engagement with the collar 54. It is thus seen that the sleeve 53 is slidable within certain limits on the standard 36, the upward movement of the sleeve 53 being against the tension of the spring 56.
As shown in Fig. 2, the wheel 50 is provided, on its periphery, with a groove 57. With the form shown in Figs. 1 and 2, the spring or elastic tape 42 (Figs. 9 and 10) which,.it is desired to secure in the casing, or hem 43 of the fabric 44, is placed upon the rollers 46 and 46, and the wheel 50 engaging in the grooves 57 and 48, the fabric being previously placed upon these wheels, as shown in Fig. 8, so that the spring or elastic insertion serves to press the fabric into the grooves 57 and 48. The operator will then fold the fabric over the spring 42, or the elastic tape, and start the machine operating, continuing to guide the folding of the fabric over, as the material travels in response to the feed of the machine. Should the machine feed and the automatic feed described herein, prove inadequate, the operator may assist the movement of the material around manually, the rollers 46 and 46 and the wheel 50 rotating to facilitate this movement.
By adjusting the relative position of the.
In the form shown in Figs. 4 and 8, a pair of wheels 58 and 58 are used, these wheels being attached to sleeves, as already described, and the sleeves being connected by a suitable shaft 58", which serves to move the wheels 58 and 58 vertically on the standards 35 and 36 in unison.
In the form shown in Figs. 6 and 7, the wheel 50" is suitably journaled on a shaft 59 projecting from the free end of an arm 59, which is pivotally connected, at its opposite end, to a pedal 60 pivotally mounted at one end to a sleeve 61, which is mounted on the standard 36.
Projectingthrough a lug 62, formed on pivotally connected to a bracket 64 mounted on the pedal 60. A spiral spring 65 is mounted on the rod 63, in embracing relation, so as to bear, at one end, against the lug 62,:1nd at the opposite end, against a nut 66, which is threaded on the rod 63. The arrangement is such that when the spring 42 is placed on the wheels in operative position in association with the fabric 44, the free end of the pedal 60 may be moved downwardly to effect the proper tension on the spring 42, a suitable catch 67 being provided for engaging the pedal 60, to retain it in its properly adjusted .position. W
I have illustrated an automatic feed, whereby the fabric may be fed by rotating, the wheels 46, instead of the operator assisting the movement of the fabric'manually. I have shown in these figures, last mentioned, mounted 011 the bed 28, a housing 68, into which projects a shaft 69 which is connected to the operating shaft upon which the fly wheel 33 of the machine is mounted. Mounted in the housing is a gear 70. A crank 71, having a stud 72 projecting from one face'of the free end, is mounted on the shaft 69, within the housing 68, said stud 72 being adapted for engaging between the teeth of the gear 70. The arrangement is such that as the operating shaft of the machine is rotated, the stud 72 will serve to rotate at intervals the gear 70.
Mounted upon the shaft 73, upon which the gear 70 is fixedly mounted, is a disc 74, which is exterior of the housing 68 and adapted to engage the periphery of a disc 7 5, which is rotatably carried, at one end, of a link 76, the other end of which is pivotally connected to the housing 68.
Projecting outwardly from the link 76 is a stem 77, which is projected through a lug 78 formed on the housing, a suitable spiral spring 79 being mounted upon the stem 77 1n embracing relation, and adapted to engage the face of the lug 78, and at its opposite end, the edge of the link 76, so as to press the disc 75 into contact with the periphery of the disc 74 sufliciently to establish a friction sufiicient to drive the disc 75.
This disc 7 5 serves as an idler and is adapted also to engage the periphery of a disc 80, which is mounted upon the shaft 81, upon which the roller 46 is mounted.- It is consequently seen that upon a rotation of the operating shaft 69 of the machine, that the roller 46 may be caused to rotate. If desired,a pair of discs 80 may be employed for rotating a pair of shafts, each connected witlli one of the wheels 46 and 46 on which user.
In the form shown in Figs. 11 and 12, I have shown the invention applied to a horizontal work table 82, in which is formed an elongated slot 83, through which is projeeted a shaft 84, upon which is rotatably mounted the wheel 85, having the peripheral groove 86 and otherwise constructed as is the wheel 50. Thewheels 87 and 88 are also provided for engaging the spring 42. By moving the wheel 85 relatively to the wheels 88 and 87, the adjustment already described may be had. j
While I have illustrated and described the preferred form of structure, I do not wish to limit myself to the precise form of structure shown, but desire -to avail myself 1, In a machine of the class described adapted for securing an endless yieldable insertion in the hem of an endless strip of fabric comprising: rotatable engaging means for engaging said fabric and said insertion, said engaging means being positioned interiorly of the loop formed by said'fabric and said insertion; rotatable stretching means movable relatively to said engaging means and being positioned in the loop formed bysaid insertion and said fabric, and adapted for stretching said insertion to the same length as said fabric preliminarily to the securing of the same therein.
