29 Claims. (Cl. 112-400) This invention relates to sewing machines and more particularly to an improved high speed cross 1 stitch laying mechanism therefor, by means of which, ornamental stitching on the top surface of the work is obtained and which improvement is applicable to different kinds of sewing machines such as long and short arm, and also tocylinder sewing. machines. manufactured by the wellknown Metropolitan Sewing Machine Corporation,rthe present invention being an improvement upon that shown and disclosed in our contemporconstructed for aneously .pending application, Serial Number 489,048,fi1ed October 16th, 1930, and is especially higher speed and increased production. i 1

. The primary object of the invention is the provision of across thread laying mechanism in Which the movements ofnthe movable thread guide,

and loop carrying finger are reduced so that the thread carrierhas a movement slightly greater than the thickness of the thread carrying finger, and'the thread carrying finger has a movement back and forth in front of the needles slightly :greater than the width or spacing of the needles .so that the loops of thread drawn olf'by thehook are just sufiicient for the needles to step over and stitch the cross threaddown ontop oi the work.

These short movementspermit the laying of a perfect stitch at high speed withoutcomplicated take-up orthread controlv means, whereas, in the prior construction, thefinger for laying the loops in front of the needle had a considerable movement many times greater thanthe spacing or width of'the needle gauge. The shorter moveanismto be operated ata speed of 4,0003. P. M.

C or more without undue wear and tear.

The prior construction of cylinder machine re- ,quired long connections from the stitching position, reachingback to the main crankshaft "of the machine. In the long arm machine, the rock shaft extending from the stitching mechanism back to the rear end of the machine was employed. In the short arm machine, the connecting rods, oscillatinglevers, etc., reaching from the stitching mechanism back to the rear end of the machine involved a great deal of weight and a considerable number of joints that were expensive to manufacture and assemble and required constant caresuchlas lubrication and adustment in use, all of which has been eliminated in this improved construction.

Therefore, an object of the invention is the provision of improved cross thread laying mechanism, simple inconstruction and operation, in- II expensive to manufacture and assemble accurately, and which will lay the thread or threads close to and directly on the material being stitched and operative with two or more needles of either wide or narrow gauge or spacing.

Since the present improvement is-applicable to various kinds of sewing machines, only a brief description of such machines is deemed necessary herein to make clear the construction and operation of the present improvement, since it. is applicable to any multiple needle sewing machine.

In the drawings accompanying and forming part of this specification, Fig. 1 is a front ,vieW of a topv and bottom rotary shaft Metropolitan sewing machine havingthis improved cross stitch laying mechanism applied thereto.

The view also shows the stitching elements including presser foot, feed, the bottom looper and also the cloth and throat plates.

Fig. 6 is an enlarged detail partly sectional sponding parts in the several views. i

Before explaining in detail the present iml provement and mode of operation thereof, we desire to have it understood that the invention is not limited to the details of construction and arrangement of parts which .are illustrated in the accompanying drawings since the invention is capable of other embodiments, and that the phraseology which we employ is for the purpose of description and not of limitation.

In the machine illustrated, the machine base i has its trunk 2 joining the base and carries an overhanging arm 3 terminating in a head l to which is attached a face plate 5. A bottom rotary shaft 6 operates in the base and a top rotary shaft 7 operates in the arm 3. These shafts are supported for rotary movement in suitable bearings. The top shaft i carries the hand wheel 8. The bottom shaft 6 carries a belt wheel 9 and is provided with the well-known three-throw cranks ii) shown in Fig. 3. The top shaft has the three well-known cranks indicated by H in Fig. 1.

Three connecting rods 22 connect the cranks of the bottom and top shafts and transmit rotary motion from one to the other. The bottom shaft 6 operates the looper and feeding mechanism well known in the art and, therefore, a detailed description thereof is unnecessary. These mechanisms are covered and protected by a cloth plate l3 in the usual way. The looper it co-acts with the two needles i5 in the formation of the stitches. The looper threads and the needle threads are concatenated with a top cross thread for the production of the stitches.

if a third needle is introduced with its thread, the mechanism will then form a different type of stitch.

The top rotary shaft '1 operates the needles l5 which are held in a chuck it carried by the needle bar I l. The needle bar has clamped to its upper end a driving member is operated by a pitman connection l9 connected to a crank pin '20 carried by the needle bar driving crank 2i secured to the top shaft l for rotary movement.

The crank pin 2 has a member 22 supporting an extension crank 23 to which is attached by a shoulder screw 24 the pitman connection 25 which operates the cross thread mechanism.

Thus, connected with the top rotary shaft is a double crank, one for driving the needle bar and the other for operating the cross thread mechanism.

The bottom end of the pitman is connected by 'a shoulder screw 2'6 to a crank arm 2?, see Fig. 6. This'crank arm is part of a shaft 28 which operates in a bearing 29 at the lower end of the machine head and between the needle and presser foot bars. To the opposite end of this shaft is attached as at 3G a crank arm 36. This arm carries a ball stud 32 that operates in a socket 33 of a connecting rod see Fig. 4. The opposite end of this connecting rod has a socket 35 that connects with a ballstud 36 secured to an arm 31 of the rock member or lever 38 carrying the thread loop finger 33 having athread engaging hook 40. This finger is adjustably secured to the member 38 and this member or lever 38 has a bearing on the presser bar #32.

A'collar 43 is secured to the presser bar just below the member 33 and carries a control piece M attached at 45 to the collar the upper end being bent at right angles to hold the member 38 in place on the presser bar during its up and down action. The presser barcarries the usual presser foot shank ll and presser foot 58. The

upper end of the presser bar d2 has clamped to ice guide piece 49, see Fig. 5, carrying a bent,

overhanging wire that co-acts with a presser foot lifting lever 5|. This lifting lever is pivoted to the back of the arm 3 as at 52, see Fig. 1, and has its rear end connected at as 53 to a downwardly extending rod 54 reaching down through the table for operation by the usual knee or foot lifting lever that is commonly used for raising the presser feet of sewing machines and by means of which the presser foot may be lifted from the work plate at will by the operator. The presser foot is held against the throat plate by a presser spring 55, see Fig. 1.

The collar 43 is provided with clamping means 56, see Fig. 5, that securely fastens it to the presser bar 42 and has a forwardly extending arm terminating in a vertical cylindrical bearing 51, see Figs. 5 and 6. In this bearing operates an oscillating thread guide 58 having a thread eye 59 at its bottom end in its laterally extending L-shaped portion. A collar 60 is secured to this member at the bottom of the bearing 5'! and. a crank arm 6| is secured to the top of the oscillating thread guide, givingto it its movement. A link 62 is connected to this crank arm by a shoulder screw 63 and a shoulder screw 84 con- 1 nects its opposite end to an arm 65 of the lever or member 38.

The operation of the thread carrying finger 39 across the path of the needles directly in front thereof cooperates with the thread eye 59 which operates from front to rear of the needles and, therefore, at right angles to the movement of the finger 39 so as to pick up the strand of thread and carry it to the right as shown in Fig. 4 to form a loop so that the needles will straddle the strand of thread extending from the eye 59 to the thread hook in the manner shown to form the stitches. The movement of the thread guide 53 is just a trifle greater than the thickness of the thread engaging hook 40. The movement of the hook is just sufficient to pass the needles from right to left to position the loop of threads for the right hand needle to enter. These short movements enable the use of a very light construction of parts capable of the highest speeds without vibration, noise or undue wear and permits the use of the mechanism for short stitches without skipping. The cross thread mechanism has a rise and fall movement with the presser foot and will accommodate itself to all thicknesses of goods being stitched. A precise amount of thread is manipulated for the requirement of the stitch. No excess takeup or see-saw action is necessary, as is usual in other machines. By the cross thread mechanism operating from the needle bar crank, the parts are entirely hidden within the head of the machine for convenient lubrication, adjustment and care. All connections are short and as direct as possible reducing the mechanism to its simplest possible form.

The stitch produced by the cross thread finger is indicated at 66 in Fig. 8. The bottom portion of the stitch is indicated at '61 and the fabric at 68. The feed dog 69 acts against the bottom of the stitch G1 and the presser foot 48 acts against the top of the stitch'BG-in the feeding of the work through the machine. The presser foot is provided with a roller 10 for conveniently guiding lace, tape or other material.

In this'improved mechanism, it will be seen that the needle and crossstitchmovement isobtained from a rotary top needle driving .shaft and note. rock shaft through the medium of adouble crank,

:one for operating .the needle bar :and the other for operating the cross stitch mechanism, thus very much simplifying the connecting means and eliminating many joints and points of wear and I operating weight and also shortening the movement of the parts so that there is no interference with high speed of the mechanism. This construction permits one finger of the cross stitch mechanism to pass in front of the needle and the thread carrier 58 to move from front to rear of the needle or at right angles to said finger and as the cross threadstitch mechanism operates around the presser bar in addition to having a rise and fall movement therewith, the construction is very much simplified, the cost of operation decreased and adds greatly to the stand-up-ability of the mechanism under continuous use. Furthermore,

an important advantage of operating the needle and cross stitch mechanism from a rotary shaft instead of a rock shaft is that precise timing and relation of movement with respect to the needle operations as well as the feed is obtained since, witha rotary driving shaft it is possible to select any position in the circle of 360 degrees, so that the relative movements of the various parts that must function within very close limits at the high speeds at which these machines operate to handle delicate threads and yarns, is not limited on the rotary shaft drive like it is on the rock shaft or needle lever drive machines and then, too, the

connections for operating the cross stitch mechanism are more direct on the rotary shaft machine rotary operatingthread take-up finger I5.

than they are on the rock shaft or needle lever machine since, on these types of machines, several connections are necessary leading from the cross stitch mechanism back to the means of drive, either leading down to the bottom shaft of the machine or to some auxiliary moving part to select a timing so that the fingers will operate in timed relation with the needles to place the cross thread for forming the stitches as desired;

An improved thread control and tension release mechanism isalso shown in this machine but this forms the subject-matter of a separat application. The threads leading to the needles I5 are indicated by II. These threads pass through eyelets I2 and around tensions I3. From there they pass to stationary thread guide I4 and past a This finger is attached to one of the crank shaftbearings at I6, see Fig. l, and because of this, has the ;,same rotary motion as the crank pin of the shaft or the rod operated thereby. This thread finger cannot wind up or in any way tangle the threads and is, in a true sense, a rotary take-up.

At the opposite side of this take-up finger is I another eyelet ll, guiding the threads from the a minimum of thread with the least amount of friction possible and at the same time, control the size of the loops deflected by the needles, regardless of the character of work being stitched. The cross thread is indicated by 83, see Fig. 1, and passes from the eyelet 84 to the tension 85 secured to the face plateELand froml thereto the crank arm eyelet 86 from where it is guided direct to the thread eye 59 of the finger 58.

The conduct of this thread is direct and with no take-up action whatever. The amount {of thread drawn off by the thread hook is precisely that which is required for the formation of each stitch. The looper thread 81 passes through a thread; guide 88 and a tension 09 and then to an eyelet 90 and then to the eye of the thread take-up finger 9|, which finger is adjustably secured in a socket 92 of the crank pin bearing 93 carried by one of the crank pins I0, see Fig. 3. The thread passes from this finger to a guide 94 andthen down under the bent end 95 of the take-up finger 96 adjustably secured in the socket 91 to the crank pin bearing 98 carried by a second crank pin I0.

The thread extends from underneath this finger up over the bent end 99 of the finger I which is adjustably held in a socket IOI to the crank pin bearing I02 carried by the third crank pin. These pins are located at 120 degrees with respect to one another and travel in a rotary path around the major axis of the shaft 6. Therefore, the ends of these three take-up fingers are traveling in a circle and act upon the threads with gentle contact for perfect control. From this third finger, the thread passes through the guide I03 and from there to the end of the thread tube I04 and thence emerges from the other end of the tube at I and passes direct to the looper as at I06.

This thread control means insures a perfect stitch formation and eliminates the skipping of stitches, tangling and winding up of threads.

To protect the fingers and prevent injury of the operator of this high speed operating machine, a metal guard I01 is secured as at I08 to the face of the machine base and is so formed that its convex side will guard and prevent the fingers from striking any moving object while I the concave side I09 provides clearance for free operation of the thread and convenient threading of the parts.

For convenience and ease in removing the work from the stitching position, .a tension release or opener is provided for the needle threads II as indicated by IIO, see Fig. 2. The opener is carried by the arm III of a sliding member 2 secured in position by shoulder screws H3 for endwise movement. The end N4 of an upstanding arm I I6 of the lever II'I operates in a slotted portion I I5 of the slide I I2. The lever lII ispivoted at IIB to the rear wall of the machine frame and has a slotted end II9, see Fig. 1, through which a pin I20 projects. This pin is carried by the foot lifting lever 53.
