23 Claims.

This invention relates to a sewing machine of the general type disclosed and claimed in my copending application Serial No. 744,642, filed September 19, 1934.

5 A prime object of the invention is to provide a novel and improved sewing machine whereby the direction of feed of the Work can be changed at will approximately instantaneously at sharp angles without manual manipulation or turning of the work and without interruption of the operation of the machine to form in one continuous operation a plurality of lines of stitches extending in different directions and meeting at angles.

The invention is especially suitable for sewing two seams of a garment at angles to each other, or sewing a label to a garment with a continuous line of stitches extending around the marginal portions of the label, although many other uses of the invention will occur to those skilled in the art.

In accordance with preferred embodiment of the invention, 1 may utilize a sewing machine which includes a drive'shaft, a stitch forming mechanism, and a work feed dog which is operatively connected to the drive shaft by connections certain of which move the dog horizontally back and forth while he other actuates the dog vertically up and down, the dog being raised 30 and moved hor zontally in one direction in engagement with the work to move the latter and then being lowered away from the work and moved horizontally in the other direction to its initial position, so that the work is moved horizontally relatively to the stitch forming mechanism. In known sewing machines of this general character the feed dog is movable horizontally in only two directly opposite directions so as to move the work in one direction, but in my 40 aforesaid copending application and in my application Serial No. 736,806, I have shown means for also periodically varying the operation of the feed dog to reverse the work feeding movement thereof. My present invention contemplates a machine of this character wherein the operation of the feed dog can be varied at will to reverse the feed of the work, or to cause the work to be fed successively in directions at right angles to each other, or to cause the work to be fed diagonally. v

More particularly the invention contemplates rovel and improved means for horizontally actuating the feed dog back and forth in opposite directions, other means for operating the dog back and forth in directions at right angles to the first-mentioned directions, and means for causing a composite or simultaneous movement of the first two mentioned means for actuating the feed dog back and forth in directions diagonal to the first two named directions, whereby, for example a garter may be stitched to a corset by continuous lines of stitches arranged in the form of a rectangle and other lines of stitches disposed diagonally of the rectangle, in one continuous operation.

A further object is to provide a multiple direction sewing machine which shall embody two needles in the stitch forming mechanism and novel and improved work feeding mechanism whereby two parallel lines of stitches may be formed in one direction and a line of double stitches can be formed at the ends of said parallel lines and disposed at right angles thereto without turning the work and without breaking of or loose threads or loss of stitches.

The invention further has in view the cooperation with all of said means for horizontally moving the dog, of a common means for operating the dog vertically or up and down to engage and disengage the work.

Other objects of the invention are to provide a machine of the character described which shall be relatively simple, reliable, durable and inexpensive in construction and operation, and to obtain other advantages and results as will be brought out by the following description. Referring to the accompanying drawings in which corresponding and like parts are designated throughout the several views by the same reference characters,

Specifically describing the illustrated form of the machine embodying my invention, the reference character A designates the bed plate of the machine which has the usual standard B ther on formed with a goose neck C at one end of which is mounted the needle bar D. The needle bar is driven in the usual way from the drive shaft E of the machine which is journaled in the standard B and goose neck C. With the need bar and its needle. cooperates a bobbin mech anism F of the usual type, the needle bar and its operating devices and the bobbin and its .journaled in the bed of the machine.

operating parts constituting a stitch forming mechanism.

The machine also includes work feeding mechanism for moving work through the stitch forming mechanism, that is, between the needle and the bobbin mechanism, and as shown, this work feed mechanism includes a feed. dog I which is movable vertically and horizontally relative to the usual throat plate 2 in the bed of the ma-' chine, the dog being raised through the throat plate and moved horizontally in one direction in engagement with the work to move the latter and then being lowered away from the work and moved horizontally in the other direction to) its initial position. Cooperating with the feed dog in the usual manner is a known type of presser foot G. The dog is operated from the drive shaft E of the machine and as shown is mounted on a link 3 one end of which is bifurcated at 4 and has a pin and slot connection 5 with a crank 6 on a counter shaft 1 journaled in the bed plate of the machine. The other end of the link 3 is pivotally connected at 8 to a crank 9 on another countershaft ID The countershaft I is rotated alternately in' opposite directions by a crank arm H connected to the shaft and having a bifurcated end 12 in which rotates a cam l3 mounted on a secondary drive shaft I4 which is journaled in the bed of the machine and is driven by the usual crank and pitman connection l5 from the drive shaft E. With this construction, the counter shaft 1 is rotated alternately in opposite directions so as to vertically raise and lower the said dog I through the throat plate 2 into and out of engagement with the work.

For actuating the feed dog horizontally back and forth to feed the work forwardly or backwardly, the counter shaft is rotated alternately in opposite directions. As shown. the

countershaft I0 has a pin l1 projecting laterally through a slot IS in the bed plate of the machine, the end of the pin being arranged to enter a slot in an actuating slide 2| so that the pin may have a hinged or pivotal connection with the slide and reciprocation of the slide will cause rotation of the shaft 10 alternately in opposite directions. As shown, the slide 2| is longitudinally reciprocable in a channel shaped guide 22 which is pivotally mounted at one end 23 on the bed of the machine.

One end of the slide 2| has a pin and slot connection 24 with one end of a lever 25 (see Figure 31) which is pivotally mounted at 26 on a horizontal axis on a bracket 2'! secured upon the top of the bed A of the machine. Carried by the lever 25 is a follower roller 28 which is arranged in the cam groove 29 of a box cam 30 (see Figure 2). This cam 30 is mounted on an auxiliary shaft 3! that is journaled with its axis vertical in bearings 32 and 33 and which has a worm gear 34 which meshes with a worm 35 on the drive shaft E. The cam groove 29 has cam surfaces 36 which will be hereinafter described in detail, so that upon rotation of the cam through the gearing 34 and 35 the lever 25 will be oseillated about its pivot to reciprocate the actuating slide 2| and rotate the co-untershaft if! when the pin I! is in the notch 20 so as to actuate the feed dog l horizontally and vary the operation thereof.

For engaging'alid disengaging the actuating slide 2! with the pin ii, the guide channel 22 is oscillated about its pivot 23, and for this purpose I have shown a knee operated lever 31 pivotally mounted intermediate its ends 38 on a bracket 39 secured to the front of the bed of the machine, one end of thelever 37 having a pin and slot connection 40 with a down-turned end of the guide channel and the other end of said lever having a knee rest adjustably connected thereto to be engaged by the knee of the operator. By pressing the knee rest M to the right in Figure lof the drawings, the guide channel may be swung to the left to cause engagement of the pin I! with the notch 20, and upon release of the knee rest, a tension spring 52 will swing the guide channel in the other direction to disengage the pin I! from the notch 20.

For controlling the reciprocation of the actuat ing slide 2| the cam surfaces 36 of the cam 30 may be of any suitable configuration, for example, as shown in my copending applications Serial Nos. 736,806 and 744,642; but for simplicity in explanation, I have shown the cam surfaces as formed and arranged to produce a continuous line of stitches of equal length. The cam surfaces for each stitch are identical, so that I shall describe only one.

Referring to Figure 2 of the drawings, each cam surface includes a dwell 43 which when engaged by the follower roller 23 actuates the slide 2| so that the feed dog is at the beginning of its forward feed movement in engageinent with the work as shown in Figure 6. In this position of the feed dog the shaft 7 has raised the feed dog into engagement with the work and holds it there during horizontal movement of the feed dog to the right in Figure 6. This horizontal movement is caused by an inclined surface 44 on the cam which causes the slide to be operated and move the feed dog to the end of its horizontal feeding movement; 1. e. at the extreme right of the opening 2 in the throatplate in Figure 6. When the feed dog reaches this position, the cam 30 has rotated to bring the follower roller 28 into engagement with another dwell 45 which interrupts horizontal move-- ment of the feed dog while the shaft '1 lowers the feed dogaway from the work. Thereupon the roller 28 is engaged by another inclined surface 46 which moves the feed dog backwardly or to the left in Figure 6 to the beginning of its forward work feeding movement. The dwell 43 then engages the follower roller to interrupt horizontal movement of the feed dog while the shaft 1 raises the feed dog into engagement with the work at the beginning of its forward feeding horizontal movement, whereupon the continued rotation of the cam 30 brings the next inclined surface M into contact with the roller to cause another horizontal feeding movement of the feed dog. This cycle is then repeated throughout the rotation of the cam, one stitch being formed during each horizontal feeding movement of the feed dog, as usual.

In accordance with the invention, the direction of feeding movement of the feed dog may be reversed at will, and as shown in Figures 1 to 6 inclusive, this reversing movement is effected by manipulation of the worm 35 on the shaft E. The worm 35 has a key or feather and spline connection with the shaft E so as to move longitudinally of the shaft, and has a circumferentiallygrooved collar 4'! in which rides a follower roller 48 on a pin l9 connected to a reversing slide 50 reciprocable in a guide bracket 51 on the top of the goose-neck of the machine.

next

The reversing slide is reciprocated by an operating bar 52 slidably mounted in the bracket 5| in a direction at right angles to the plane of reciprocation of the reversing slide 50. The operating bar has a cam slot 53 which engages a pin 54 on the reversing slide so that upon movement of the operating slide in opposite directions, the reversing slide is reciprocated in opposite directions respectively. Any suitable manual or automatic means may be utilized for moving the operating slide, but I have shown a foot lever 55 connected by a chain or cord 56 to one end of the operating slide for moving the slide in one direction, a tension spring 51 being provided for moving the slide in the other direction upon release of the foot lever. If desired, a handle 58 may be provided on the operating slide for actuating it in both directions.

The ratio of the movements of the various parts is such that when the reversing slide 55 is moved in either direction, the worm 35 is slid on the shaft E a distance sufiicient to rotate the cam 30 in one direction or the other relative to the follower roller 28 a distance adequate to cause a reversal of movement of the feed dog. This manipulation or adjusment of the cam is schematically illustrated in Figures 9 to 11 inclusive. Assuming that in Figures 9 and 10 the cam is rotated in the direction of the arrows and the follower roller 28 has moved from the position of Figure 9 to the position of Figure 10 so as to have completed a forward feeding'movement of the feed dog, operation of the reversing slide 50 to the right in Figures 2, '7 and 8 will cause the cam to be moved in the opposite direction as indicated by the arrow in Figure 11 so that the roller and cam will be returned to the same relation as shown in Figure 9. This will result in a movement of the actuating slide and feed dog backwardly or in a direction opposite to the movement effected during operation of the parts from the position shown in Figure 9 to the position shown in Figure 10. Therefore, upon resumption of normal rotation of the cam 30 in the direction of the arrows shown in Figure 9, the feed dog will feed the work backwardly. In other words, the dog will engage the work while it is moving from right to left of Figure 6 instead of while it is moving from left to right. This reversal of movement of the feed dog may be effected at any time and in any position of the feed dog. When this reversing movement of the feed dog takes place while the shaft 1 is moving the feed dog downwardly away from the work, no stitches will be formed during the reversal, but when the reversal is made while the feed dog is in engage,- ment with the work, a stitch will be produced on top of the next preceding stitch. Obviously movement of the operating slide 52 in opposite directions will cause reversals of movement of the feed dog in opposite directions respectively. Preferably, the feed dog has a knurled surface to properly grip the work on movement in both directions.

In Figures 43 to 56 inclusive are illustrated the operations of the feed dog in forward feeding and reverse feeding of the work. Figure 43 shows a line of stitches formed upon forward feeding of the work and Figure 44 shows the position of the feed dog i at the end of the .forward feeding movement where the dog is in its upper position in engagement with the work W shown in dot and dash lines. Figure 45 shows the dog lowered away from the work as the result of movement of the shaft 1 while Figure 46 shows the movement of the dog to the beginning of its forward feeding stroke but out of engagement with the work. Figure 47 shows the dog raised into engagement with the work preparatory to beginning the next forward feed of the work and Figure 48 shows the dog at the end of the forward feeding. When the operating slide 52 is actuated to reverse the direction of the work with the feed dog in the position shown in Figure 48, the dog is moved backwardly as shown in Figure 49. Thereupon the dog is lowered away from the work as shown in Figure 51 and then forwardly out of engagement with the work as shown in Figure 52 and then upwardly into engagement with the work as shown in Figure 53 and then backwardly in engagement with the work as shown in Figure 54 so as to move the work backwardly. This results in a reverse stitch designated by the reference character a in Figure 50. The dog is then moved downwardly away from the work after which this cycle of operations may be repeated to form a double row of stitches designated b in Figure 58.

The invention also contemplates a lateral or sidewise feeding of the work, and for accomplishing this result, I have shown the feed dog laterally horizontally reciprocable. Specifically the crank 9 has a keyed or feather and spline connection with the shaft l so as to slide longitudinally of the shaft and is influenced in one direction by a compression spring 59 interposed between the crank and a collar 60 on the shaft The crank has a lateral arm 6| to one end of which is connected a pull rod 62 the other end of which is connected to one arm 63 of a bell crank lever 64 which is journaled on a stub shaft 65 on the bed of the machine. The other arm 66 of the bell crank has a head 61 to engage a notch 61' in the actuating slide 2|. With this construction, when the actuating slide is connected to the head 61, reciprocation of the slide by the lever 23 will cause oscillation of the bell crank lever 64 and consequent horizontal lateral movement of the crank 9 and feed dog I (see Figure 42). This horizontal lateral movement of the feed dog has a timed relation to the vertical motion of the feed dog effected by the shaft 1, corresponding to the timed relation of the horizontal longitudinal movement of the feed dog and said shaft 1. The bifurcated end I2 of the link 3 slides longitudinally of the pin on the crank 6 to compensate for the sliding of the crank 9 longitudinally of the shaft [0.

Another feature of the invention is means for causing feed of the work in directions which are composites of the longitudinal and lateral feeds, that is, a feed of the work diagonally. This diagonal feed may be effected by causing oscillation of the crank 9 and longitudinal movement thereof on the shaft ID at the same time; in other words, by causing the actuating slide 2| to engage both the pin I! and the head 61 of the bell crank lever 64. In order to so simultaneously connect the pin l1 and the head 61' to the actuating slide I have shown the arm 66 of the bell crank lever as extensible. In Figures 12 to 16 inclusive, this arm 66 includes a main portion 69 on which is longitudinally slidable an extension portion at the end of which is mounted the head 61. A latch H is pivotally mounted on the extension ill to cooperate with openings 12 in the main section 69 for holding the extension 10 in adjusted positions. When it is desired to connect the head 61 to the actuating slide 2| simultaneously with the connection of the. slide to the pin ii, the extension i9 is slid outwardly into the position shown in Figures 15 and 16, while when it is desirable to connect the actuating slide 2| to either the pin I! or the head 61, separately, the extension 10 is slid inwardly into the position shown in Figures 12 and 14. When the extension is in this position, the actuating slide 21 may also be located in neutral position,

that is, unconnected with either the pin it or the head El as shown in Figure .12. As shown, the head 61 and pin ll are preferably located at opposite sides of the slide 21 to facilitate these operations.

In operation of the mechanism, when the actuating slide 21 is in neutral position as shown in Figure 12 the slide may be reciprocated by the lever 25 without any horizontal motion of the feed dog. To cause horizontal longitudinal motion of the feed dog, the actuating slide 2! is swung to the left as shown in Figure 13 to engage the pin 17, while when it is desired to cause simplylateral motion of the feed dog, the actuating slide is swung to the right as shown in Figure 14 to engage the head 61, while when diagonal motion of the feed dog is desired, the actuating slide is swung into engagement with the pin I! after which the bell crank arm 66 is extended to engage the head 6? with the actuating slide, as shown in Figure 15.

Figure 17 is a schematic plan view of the feed dog operating mechanism with the parts in neutral position, while Figure 18 shows the parts in the position assumed for beginning longitudinal horizontal movement of the feed dog. Figures 19 and 20 show the actuation of the slide 2! and the feed dog E successively in opposite directions.

Figures 21- to 23 inclusive show the corresponding steps in the horizontal lateral reciprocation of the feed dog. Figure 24 shows the position of the parts preparatory to beginning diagonal horizontal actuation of the feed dog, while Figure 25 shows the completion of the adjustment of the parts for such diagonal lateral motion.

Figures 26 and 27 show the operation of the parts successively in opposite directions during diagonal actuation of the feed dog and Figure 28 shows the disconnection of the head 81 from the actuating slide.

With the feed dog moving horizontally either longitudinally, laterally or diagonally the dog may be caused to move in either of the other two directions at the will of the operator. Furthermore, the feed dog may at will be caused to feed in either of opposite directions longitudinally, laterally or diagonally. In Figure 57 the feed dog is shown as having been changed from backward longitudinal feeding to lateral feeding, the dog being disengaged from the work at the begin ning of lateral feeding of the work in the direction of the arrow. Figure 59 shows the dog raised into engagement with the work at the beginning of the feeding movement while Figure 61 shows a dog at the end of the feeding movement. Figure 62 shows the dog being lowered away from the work and Figure 63 shows it returned to the initial position shown in Figure 57. With the dog moving in this manner, a lateral line of stitches 0 may be formed. In Figure at the direction of lateral movement of the dog is shown as changed so as to reverse the direction of feed of the work as indicated by the arrow,

the dog being disengaged from the work. Figures 65 and 66 show the dog atthe beginning and ending of its feeding movement respectively, while Figure 6'7 shows the dog lowered away from the work at the end-of the feeding movement. This operation will result in a double line of lateral stitches 0 shown in Figure 64. Figure 68 illustrates a change in the movement of the dog from lateral feeding to diagonal feeding, the dog being shown out of engagement with the work. In Figure '70, the dog is shown as moved out of engagement with the work to the beginning of its diagonal feeding motion while Figure 71 shows the dog raised into engagement with forward longitudinal feeding, Figures '75- to '77 showing the cycle of operations of forward feeding from a line of stitches e. In Figure 78-the position of the dog is shown as again changed to feed diagonally in the direction opposite to that illustrated in Figures 70 to '72 inclusive so as to form a diagonal line of stitches f; Figures 80 to 82 inclusive show the steps in the cycle of movement of the dog. In Figure 33 the direction of movement of the dog is again illustrated as longitudinally forward to form a stitch g, Figure 84 illustrates the end of the forward feed movement. In Figure 85 the dog is shown as stationary as when the-machine is stopped.

All of the stitching hereinbefore described, is formed with a single needle, out the invention is of course susceptible of use in a two. needle machine. Here two needles are used, parallel rows of stitching hand i may be formed as shown in Figures 8'7 and 39 or arow ofdouble stitches k may be formed in one operation as shown in Figure 88. By feeding the work longitudinally parallel rows Z of single stitches may. be formed, and then by feeding the work laterally a row of double stitches m may be formed at right angles to the rows Z. scribed is simply illustrative of the many different forms of stitching which may be accomplished with my machine, and it will be understood by those skilled in the art that the machine may be used for making various forms of stitches without departing from the spirit or scope of the invention. a

It will be understood from the foregoing that the drive worm 35 in connection with the re? versing slide 50 may be utilized for reversing the direction of movement of the feed dog when the dog is moved either longitudinally, laterally, or diagonally.

Instead of manipulating the worm 35 to reverse the direction of feeding movement of the feed dog, I may move the follower roller 28 rela- The stitching detively to the cam. A structure for accomplishing 19 journaled in the bed of the machine and having a crank arm 86 which is connected by aslide.

link 8! to the bracket. Obviously, by sliding the bracket laterally, the position of the follower roller 28 relative to the cam may be varied as shown in Figures 39 to 41 inclusive. This adjustment corresponding to that illustrated in Fig ures 9 to 11 inclusive for efiecting reversal of the direction of movement oi the feed dog.

To compensate for the sliding movement of the bracket, the pin and slide connection between the lever 25 and the actuating slot 2! must permit lateral movement of the lever relative to the slide, and as shown in Figure 34 the slot in the lever may be elongated as indicated at 83 to slide laterally of the pin or stud 84 on the actuating The machine shown in Figures 29 to 36 otherwise operates in the same manner as the machine shown in Figures 1 to-6 inclusive.

Figures 37 and 38 are schematic comparative views of the two ways of causing relative adjustment of the cam and follower roller, Figure 3'7 showing the adjustment eiiected by movement of the worm 35 as shown in Figures 1 to 6 inclusive, while Figure 38 shows the adjustment efiected by moving the bracket as shown in Figures 29 to 36 inclusive.

Instead of moving the followerroller 28 relative to cam 30 for reversing the feed, I may provide any suitable known type of reversing mechanism for simply reversing the direction of rotation of the cam.

While I have shown the cam 39 in the form of a box cam, it will be understood that a plain cam 82 may be utilized as shown in Figure 32. However, where a plain cam is used, a spring 10A must be provided for holding the follower roller in engagement with the cam (see Figure 3 of the drawings).

It will be understood that the invention is also susceptible of use in a sewing machine having a vibratory or oscillating needle bar.

While I have shown and described my invention as embodied in certain details of construction and as utilized for certain purposes, it should be understood that this is primarily for illustration of the principles of the invention, and that the machine may be embodied in other details of structure and used for other purposes without departing from the spirit or scope of the invention.
