SEWING-MACHINE.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed January 31, 1916. Serial No. 75,392.

To all whom it may concern Be it known that 1, ROBERT L. LYONS, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in sewing machines and particularly to sewing machines adapted at a single operation to sew to a piece of material a stay located at one side of said material and a button located at the other side of said material. The present machine being for the general purpose of the machine described in my U. S. Letters Patent, dated November 16, 1915, No. 1,160,423.

The purpose of the present invention is to simplify and improve the stay or stay button holding device in order that, in some classes of work, said stay or stay button may be positively held from independent lateral movement and may be yieldingly held by means adapted tobe acted upon by the presser foot to positively hold said stay or stay button from movement in one direction during the sewing operation and to permit the release movement of said stay or stay button after its attachment to the material.

Other objects of the invention will appear from the following description.

The invention'consists in such novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, represents a side elevation of the improved machine parts thereof being in section.

Fig. 2, represents a sectional plan view of the sameas taken on line 22 Fig. 1, a stay or stay button being shown in its holder.

Fig. 3, represents a sectional enlarged view of parts thereof taken on line 3-3 Fig. 2, showing the work after the sewing operation andbefore the thread is broken or severed.

Fig. 4, represents a similar view showing the work raised by the lifting of the button clamp and the stay about to leave its yielding holder member.

Fig. 5, represents a cross sectional view of the work approximately as it will appear as on line 55 Fig. 4: after the release of the stay from its holder member while the main button still is retained by the arms of the button clamp.

Similar charactersof reference designate corresponding parts throughout.

The term stay, used herein, is intended to refer t0v a stay button or any rigid or flexible reinforcing device or material adapted to so reinforce or distribute the pulling or cut-' ting action of stitches which attach a button or other article to a piece of material as to reduce the liability of said stitches being pulled through said piece of material.

Although my new invention is not necessarily restricted in its use thereby, it is to be understood that the invention is particularly applicable to button sewing machines having vibratory button clamps or work holders adapted to effect movement of the work relative to the stitch forming devices during a series of operations of said devices, said machinespreferably having cooperating means to effect the breakage of the thread.

As shown in the drawings the machine herein employed to illustrate this invention 6 indicates the bed of a sewing machine hav ing the standard 7 furnished with the arm 8 which carries the head or guide member 9 in which is slidably mounted the needle bar 10 furnished with the needle 11. J ournaled in bearings of the bed 6 is the shaft 12 which, through any usual and well known mechanism, not shown, is adapted to operate the needle bar 10 and the looper 13 which latter is positioned as usual relative to the path in which needle ll'operates.

Shaft 12 has the usual worms 14 and 15 through which the gears 16 and 1 7 of the button clamp controlling or moving cams 18 and 19 are driven. These cams 18 and 19 have the cam grooves or ways 20 and 21 the walls of which act against the followers 22 and 23 to effect vibration of the arms 24 and 25 which vibration or vibratory movement is transmitted through the shafts 26 and 27, journaled in bearings of the machine, and through connections usually employed for such purpose, to effect movement of the button clamp or work holder 28 relative to the needle whereby a group of stitches may be sewn.

Button clamp Or work holder 28 has the base 29 having secured thereto the cloth plate 30 of novel construction in that this plate 30 has the opening 31, of a size or diameter slightly greater than the distance which this portion of the work holder is moved in the vibratory action of the button clamp, and in the body of this cloth plate 30 above said opening 31 is the stay receptacle 32 of a. diameter larger than the opening 31 whereby the body of said cloth plate 30 em bracing said opening 31 constitutes a supporting member for a stay and the wall 33 of said receptacle 32 constitutes a holding device or means which prevents independent movement of the stay or button received by said receptacle. At the upper surface of the cloth plate is positioned and preferably secured the spring bearing member 34 which at its free end overlies the receptacle 32 somewhat and has the semi-circular or other suitably shaped opening or clearance 35 having the indicator slot 36 extending radially of said clearance or at least in a direction to permit this slot 36 to receive a part of a group of stitches.

The button clamp has the button holding arms 37 so mounted. in the usual manner that they maybe swung upward to facilitate the placing of the work in position for operatiop and the removal of said work after the operation. The provision herein shown for raising the free ends of said arms 37 comprises the chain 38 connecting said arms with the lifter arm 39 of shaft 40 which latter is journaled in bearings of the machine and may be operated in any desired manner.

The stay A is usually a button or similar member of a size and shape to be received by the receptacle 32 within its holding wall 33. This stay or button A usually has two or four holes, as the case may be, and one purpose of the slot 36 of spring member 34 is to indicate the line on which the bar between the holes of the button should extend while the button clamp is at rest in order that, during the operation of such button clamp, said holes may at suitable times be brought into registry'with the path of the needle. This slot, notch or indicator 36 of course is also of assistance in arranging the position of the stay or button A relative to the proposed position of the button B which is placed in the usual manner between the button holding arms 37 of the button clamp whereby the holes of said stay andsaid button may be in registry.

The stay or button A is placed in the receptacle 32 either by lifting the free end of the spring bracing member 34 and placing the stay A in said receptacle or by introducing the edge of said stay beneath said free edge of said member 34 and then pushing said stay into said receptacle after which member 34 will bear against and frictionally engage the surface of said stay sufliciently at least to retain the same in the position, to which it is adjusted by rotation in said receptacle, to permit the needle to pass through its holes in the sewing operation.

After the placing of the stay A in position the free end of the button clamp, arms 37, is raised and the material C, to which the clamp is raised tofacilitate the removal of the button B from the arms 37, approximately as shown in Fig. 4, the free end of spring member 34 will be raised by reason of its engagement with the stay A and this stay A will of course be raised with the button B to which it is attached. The work may now be drawn from the machine and the member 34 will then spring back into place. It is of the work is in the position shown in Fig. 4 another stay may be placed in the receptacle 32.

Having thus described my invention I claim as new anddesire to secure by Letters Patent.

1. A stay and button sewing machine comprising a work holder having a cloth plate provided with a needle openin and a recess constituting a stay receptac e extending from said needle opening, means to frictionally engage a stay in said receptacle, and button holding means mounted on said work holder.

2. A stay and button sewing machine comprising a work holder having a cloth plate furnished with a needle opening and a stay receptacle extending from said needle opening, a spring member carried by said cloth plate and overlapping said receptacle, and button holding means mounted on said work holder.

3. A stay and button sewing machine comprising a work holder having button holding arms and a cloth plate furnished with means to sustain a perforated stay underlying said .button holding arms, said cloth plate having means to indicate the position of the perforations of the stay relative to the perforations of the button.

4. A stay and button sewinomachine comprising a button clamp, a clotli plate mounted to move coincidently with said button clamp and having a stay receiving cavity and means to indicate the location of the holes of a stay in said cavity relative to the path of the needle.
