Serial No. 818,183.

To all whom it may concern Be it known that 1, JOHN Fmu, a citizen of the United "States, and resident of the city, county, and State of New York, have invented a certain new and useful Improvement .in SewingMachines, of which the following is a specification. I

I My invention relates to that class of sew ing or embroidery machines in which cording or analogous material is secured to fabric by means of a thread carried around or through said material and around the thread of stitching formed on the fabric.

More particularly my invention relates to a device by means of which machines of this class may be utilized to attach spangles, as they are commonly sold in strip or tape form, to the fabric by concealed stitches.

A further object of my invention is to provide a device of the character specified by means of which two strips or tapes of spangles may be simultaneously stitched to the fabric 0 as to constitute an ornamental, pleasing and unitary stripe of ornamentation' thereon.

My invention will be better understood by reference to the drawings in which Figure 1 represents, in front elevation, a view of a part of the head of a standard embroidery machine of the type specified, said head being provided with the device of my invention as made to attach a single strip of spangles; Fig. 2 is a view taken from the right of Fig. 1; Fig. 3 an enlarged detail view, taken from the same point of view as Fig. 2 but showing only the device proper as it appears while the strip of spangles is actually being sewed upon the fabric; Fig. A shows a plan view of a part of a strip of spangles after it has been sewed upon the fabric; Fig. 5 is a .view similar to that of F 8 but showing the device for simultaneously attaching two strips of spangles; Fig. (3 is a view of Fig. 5 taken from the right; Fig. 7 is a view showing the appearance of the two strips of spangles after they have been attached to the fabric by the device of Figs. 5 and (3; Fig. 8 is a view taken from the underside of Fig. 7; Fig. 9 is a perspcclive view of the device of my invention as used for attacl'iing a single strip of spangles; Fig. 10 is a similar .view of my device when arranged for attaching a pair of strips of spangles; Fig. 11 is a section taken along the line 11-11 of Fig. 10; Fig. 12 is a detail showing a plan view from below of the block 12.

Referring to the drawings the head, 1, of the machine is provided with the usual holding member, 2, for the needle, which member is adapted to be reciprocatcd vertically in the usual manner. A member, 3, usually employed in machines of this type to carry a suitable needle guide is also present, but the needle guide is removed and replaced by the device, 11, of my invention, which comprises, in substance, a combined needle guide and a guide forthe strip of spangles. This guide l comprises structurally a-clamping bar 5 having 'ertically arranged slots, (3 and 7, and a central bearing stud 8. Threaded spindles 9 and 10 attached to the member 3, and provided with clamping screws, eooperate with the two slots, (3, 7, to attach the clamping bar 5, to the head of the machine. By mutual adjustment of the two clamping screws of the two spindles t) and 10, clamping bar 5 may be rocked upon the stud 8 so as to accurately adjust the needle guide in corres 'iondence with the needle.

The lower end of the clamping bar is provided with an inwardly bent extension 11 which carries at its bottom the guides proper previously referred to, namely, the needle guide and the guide for the strip of spanglcs. These guides compris substantially a rehu tivcly thin flat block 12 held with its plane pcrpeinlicular to the bed of the machine and provided with an open longitudinal slot 13 extending from the bottom almost to the top of the block; this slot is slightly deeper on one side than on the other and this maximum depth is substantially equal to the diameter of the spangles. The top of the slot at the side of minimum depth, which is pref;- erably the side away from the member 11, is pierced with a hole 13 into which the needle is introduced and which serves to guide and determine the vertical line in which the needle works. This hole 13 is so located upon the top of the block that it partially overlaps the inner edge of the slot which edge is grooved beneath the hole so as to correspond therewith; the needle reciprocates in this groove and against the inner wall of the slot. The top ot the slot 13, on the left of hole 13' is gently curved upwardly and outwardly (as at 13", Figs. and 3) and a wire l-lsupported by the block just above this curved portion extends upwardly and outwardly and terminates in an elongated slot 15 arranged parallel to the slot 13 in a plane, preferably, parallel to the bed plate;

The stri of spangles shown in the drawings is the usual well known article of commerce in which a series of fiat circular spangles, or pairs of spangles, is threaded upon a thread so as to hold thespangles permanently in the same relative position to one another. r i

In the operation of my inventionthe strip of spangles, 16, to be attached to the fabric is wound upon a spool.(not shown). suitably held in the usual manner upon the machine. The end of the strip is threaded down through the tube 17 in the usual manner, then through the slot 15 and then into and through the slot 13 of the block 12. The cord side of the spangles should be facing the groove of the needle guide 13. By rea son of the twoslots 13 and 15 the strip of spangles is held on edge against the bed plate. The fabric to which the spangles are to be attached having been positioned, the

machine is operated in the usual manner and the needle 18 as it descends in the needle guide and groove will pass through the system of cords 19 which holds the spangles together and into the fabric. A the operation of the machine is continued the strip of spangles is sewed fast-to the fabric. lBy reason of the constant tension on the sewing threads the spangles, as soon as they pass out of the slot 13, begin to pass from the vertical position and eventually are drawn flat against the fabric. The stitch which holds the spangles fast upon the fabric is entirely invisible from the upper side of the fabric as appears from Fig. 4. The strip ofspangles may be placed upon the fabric so as to embody any desired design by rotating the head of the machine by meansof the usual crank holder.

The guide for use in attaching a pair of spangle strips to the fabric is very similar to the one just described for a single strip. except that a pair of slots is provided in the guide block, one slot for each strip of spangles, while the needle guide is widened (across the length of the strip of spangles) in order that the needle may be oscillated at each alternate stitch so as to alternately stitch through the threads of the two strips. More in detail the double guide comprises the block 20, held at the bottom of member 11, as before, and provided with a wide slot 21 and an elongated needle guide, 22, at right angles to the slot. This slot, 21, is in reality two slots, there being a thin central partition, 24:, in one side of the slot dependent from the roof of the slot 21. At one end of the block 20 is a guide 25 concaved inwardly toward the block and held upwardly and outwardly from the block by an arm 26.

In operation the two strips of spangles are held by suitable spools (not shown) fixed upon the machine and carried down the central tube 17 with their connecting threads adjacent and with the strips flat upon one the connecting threads being adjacent the spangles themselves will be pushed away from one another and against the outer walls of the slot 21. As the two strips pass the guide 25 they are positioned respectively by the pairs of grooves 25 and 26, the members of each pair being cut respectively in the guide 25 and the block 20. The needle, 18,- as it reciprocates vertically, lies at one side of slot 22 so as to pass through the connecting thread of the strip of spangles lying on the'corresponding side of slot 21, and then, at the next stitch, lies at the other side of the slot 21, so as to pass through the connecting thread of the second strip of spangles, and so on alternately. Each strip, is therefore, sewed fast to the fabric although the same thread is used to attach both strips. Because the strips lie so close together as they pass through the guide they will, after they are stitched upon the fabric and pass from the guide, incline toward and upon one another so as to roduce a unitary strip of spangles of wldth nearly double that of a single strip; the center line of this double strip will be raised so that the strip will be triangular in cross section. The double strip, like the single strip first referred to, may be stitched to the fabric in any desired ornamental design by rotating the head of the machine in the usual manner by the usual crank holder.

In making the device of my invention I do not needto make it exactly as shown and described so long as the various guiding elementsare provided and changes of form may be made within the scope of the following claims.

ll claim- 1. In a machine of the type specified, a device whereby a strip of spangles may be stitched to fabric comprisinga needle guide and means for guiding the strip of spangles on to the fabric'with the length of the strip parallel with and the plane of the strip perpendicular to said fabric and into and at one side of the needle guide so that the needle will pass through the cord holding the spangles together but will clear the spangles.

2. In a machine of the type specified, a device whereby a strip of spangles may be stitched to fabric comprising a block adapted to be attached to the head of the machine and slotted from below to a depth substantially equal to the diameter of the spangles,

means for guiding the strip into said slot, and means for-guiding the needle within said slot so as to pass throu h the cord holding the spangles together ut so as to clear the spangles 3. In a machine of the type specified, a device whereby a strip of spangles may be stitched to fabric comprising a combined needle guide and strip guide adapted to be attached to the head of the machine the strip guide including a slot for holdin the stri of spangles on edge against the abric wit the spangles at one side of the needle uide, in combination with means for intro ucing the strip into said slot.

4. In a machine of the type specified, a device whereby a strip of spangles may be stitched to fabric comprising a block provided With a guide for the needle and a slot opening from below for holding the strip on edge against the fabric the needle guide opening into the top of the slot and away from the side thereof against which lie the spangles proper.
