Description
CREASE ELIMINATING DEVICE
FOR A SEWING MACHINE
This invention relates to a crease eliminating device for a sewing machine; particularly, this invention relates to a device which can automatically adjust the distance between the pulling wheel and the needle plate of a sewing machine so as to provide the pulling wheel with a suitable pulling speed and pressure to be applied on a cloth material being sewed, thereby preventing creases forming in the material.
Generally, when sewing a cloth material or the like on a sewing machine, the material has to be kept flat and slightly taut; otherwise, the material being sewed may crease.
Frequently, when a tailor sews a garment or the like with a conventional machine, he (or she) has to pull the cloth material with both hands at the front and rear parts of the cloth material to prevent creasing;- materials such as silk fabrics or plain cloth are particularly susceptible to creasing. Therefore, the only way of eliminating creasing is to pull the cloth material during sewing.
It is known to provide a sewing machine with a pulling member, which is usually situated behind the sewing assembly. The pulling member is merely a pulling wheel structure situated behind the pressing foot of the sewing machine. During a sewing operation, the tailor can maintain the cloth material in a flat and taut state upon pulling the cloth material forwards, and therefore a sewing machine equipped with such a pulling member can allow faster sewing. However, when sewing a thicker cloth material, the pulling. wheel pushes the pulling member upwards a small distance so as to increase the distance between the pulling wheel and the needle plate, thereby allowing the cloth material to pass smoothly.
Unfortunately, when the pulling wheel is pushed upwards by the thick cloth material, the pulling member cannot be raised; in other words, the pulling member usually has to be adjusted and set at a given height for the thickness of a given cloth material and therefore the pulling wheel can only work properly with cloth material of the set thickness. If a pocket or a cuff portion is being sewed, so that the thickness of the cloth material is increased, the thicker cloth material is unable to pass through the pulling wheel because the whole assembly is unable to move. The cloth material may therefore jam, or the pulling speed and pressure applied to the cloth material may vary thereby causing creasing in the cloth material.Briefly, the aforesaid conventional pulling member is unable to keep the cloth material flat and taut if the thickness of the cloth material is liable to change; on the contrary, the pulling member can cause creases in the cloth material because it cannot provide the correct pulling speed and pressure; in which case the quality of the garment sewed deteriorates.
In view of the aforesaid drawbacks of conventional sewing machines, the inventor has developed a swinging arm with a pulling wheel; by means of a minor adjusting screw, a downward pressure is applied to the swinging arm so as to maintain a distance between the pulling wheel and the needle plate, and that distance is adjustable in accordance with the thickness of a cloth material being sewed. The pulling wheel can therefore adapt to cloth material having different thicknesses and can pull the material with the correct pulling speed so as to prevent creasing; this is the prime object of the present invention.
Another object of the present invention is to provide a pulling wheel which is detachably mounted to one end of a drive shaft. Several pulling wheels may be provided each having a different form (varing in shape or width, for example) to suit various cloth materials.
Still another object of the present invention is to provide a swinging arm having a pulling wheel, which can swing free at a given angle; that angle can also be varied by adjusting the position of a movable rod, and then the position of the pulling wheel will also be varied in front or rear direction, whereby the distance between the pulling wheel and the pressing foot will be changed; in other words, the present invention is compatible with various kinds of sewing machine.
In conventional crease-eliminating devices, the pulling member and its driving motor are mounted on the left and right ends of the sewing machine base respectively; mechanical power is transmitted with a transmission shaft across the mid-portion of the sewing machine base; such an arrangement may be inconvenient to the sewing machine operator in use.
A further object of the present invention is to provide a driving motor, whose power supply is controlled with an electronic circuit, and whose mechanical power is transmitted with a belt; the two parts are mounted on the rear end of the device so as to minimise inconvenience in use,
An embodiment of this invention will now be described, by way of example, with reference to the accompanying drawings in which::
Figure 1 is a perspective view of an embodiment according to the present invention;
Figure 2 is a disassembled view of the embodiment shown in Figure 1;
Figure 3 illustrates the manner of operation manner of one aspect of the present invention;
Figure 4 illustrates the manner of operation of another aspect of the present invention;
Figure 5 is a sectional view of the aspect of the invention shown in Figure 3;
Figure 6 illustrates the manner of operation of a further aspect of the present invention.
As shown in Figures 1 and 2, an embodiment of the present invention comprises a frame 1, a movable rod 21, a supporting rod 22, a main support 3, a swinging arm 4 and a driving motor 5. The frame 1 is used to attach the crease eliminating device to a sewing machine; the frame 1 includes a fixing base 11, an upper frame 12 and a lower frame 13. The fixing base 11 has a screw hole 111, and the fixing base 11 is fixedly mounted to the frame of a sewing machine by means of a screw bolt so as to attach the crease-eliminating device to the sewing machine. The upper frame 12 and the lower frame 13 are parallel to one another and are furnished with two sets of co-axial sliding holes 121 and 131 respectively so that the movable rod 21 and the supporting rod 22 can slide up and down between the upper frame 12 and the lower frame 13.
The movable rod 21 is provided with a stop block 211 which limits the downward movement of the rod 21.
The lower end of the movable rod 21 is fixed to the main support 3; the extent of downward movement of the main support 3 depends upon the position of the stop block 211; therefore, adjustment of the position of the stop block 211 by means of a fixing screw 211 changes the limit of downward movement of the main support 3 i.e.
the height between the main support 3 and the needle plate. This height determines the angle of the swinging arm 4 and therefore determines the position of the pulling wheel 47 (i.e. the distance between the pulling wheel 47 and the pressing foot) for the purpose of adjustment.
The upper end of the movable rod 21 is mounted
inside an elasticity regulating screw 213, which has a through hole to allow the movable rod 21 to move up and down. The outer surface of the screw 213 has threads whereby the screw may be fixed to the upper frame 12. A spring 212 is mounted between the lower end of the elasticity regulating screw 213 and the upper portion of the movable rod 21 so that the movable rod 21 is forced downwards so as to press the stop block 211 onto the top surface of the lower frame 13, and to keep the main support 3 within a positioned limit controlled by the stop block 211. Further the elasticity regulating screw 213 may be used for changing the force of the spring 212 applied to the neck portion of the movable rod 21. The rear end of the lower frame 13 is furnished with a pulling handle 2112.Since the end of the pulling handle 2112 which is connected with the lower frame 13 has a cam portion, operation of the handle causes the stop block 211 and the movable rod 21 to be elevated when the handle 2112 is pulled upwards; the main support 3 connected with the lower end of the movable rod 21 is lifted up simultaneously. The pulling handle 2112 not only lifts up the stop block 211, but also can hold the stop block at its highest position. The cam may operate in one of many ways known in the art, and therefore its function is not described in detail.
The supporting rod 22 is also connected to the main support 3; therefore, it can move up and down simultaneously with the movable rod 21 to assist the movable rod to guide the main support 3. The movable rod 21 and the supporting rod 22 are mounted on the main support 3 by means of nuts, and a base plate 32 is also mounted under the main support 3 with the same nuts.
Both the movable rod 21 and the supporting rod 22 can be guided within the sliding holes 121 and 131 to move up and down between the upper frame 12 and the lower frame 13; therefore, the main support 3 can be moved up and down relative to the frame 1.
The lower end of the main support 3 is attached with an axle 31 for pivotally connecting the swinging arm 4 with the main support 3. The extended end of the axle 31 is mounted with a driven belt wheel 52. The front and extended portion of the base plate 32 on the main support 3 is mounted with a small elasticity adjusting screw 321 and a lifting stopper 322. The adjusting screw 321 is movably mounted in the base plate 32, and the lower end of the screw 321 is attached to a stopping rod 3211; a spring 3212 is mounted between the stopping rod and the base plate 32 so as to provide a downward pressure upon the swinging arm 4, and also to provide a pressure upon the cloth material. The downward pressure of the spring 3212 applied to the swinging arm 4 may be adjusted by adjusting the distance between the adjusting screw 321 and the stopping rod 3211.The lifting stopper 322 is used for limiting the maximum lifting limit of the swinging arm. The stopping screw is a screw bolt threadedly attached to the base plate 32 for adjusting the maximum lifting limit of the swinging arm 4 in accordance with the thickness of the material being sewed. The rear side of the main support 3 is provided with a motor frame 33 for attaching the driving motor 5 thereto.
The swinging arm 4 of the pulling wheel 47 includes a wedge-shaped box, in which'a driving bolt wheel assembly and a gear train assembly are mounted for transmitting the driving power from the axle 31 to the pulling wheel 47. The swinging arm 4 is pivotally mounted to the main support 3 by means of the axle 31 and two bushes 40. The swinging arm 4 can not only pivotally swing about the axle 31, but also can transmit the driving power, via the axle 31, to the driving wheel 411 of the second belt wheel assembly. The axle 42 of the driven belt wheel 52 is provided with a driving gear 43, which is engaged with an idle wheel 44 and a driven wheel 45. The driven wheel 45 is mounted on a shaft 46; one end of the shaft extends out of the swinging arm 4, and is attached to the pulling wheel 47.One of the front sides of the swinging arm 4 is mounted with a guide fork 48, which has a U-shaped slot 48, for receiving the pressing foot rod so that the swinging arm 4 lifts up simultaneously with the pressing foot.
The rear end of the swinging arm 4 is furnished with a descending stopper 49; when the main support 3 is lifted upwards, the front end of the swinging arm 4 falls downwards until the stop screw 49 engages with the bottom end of the movable rod 21. If the main support 3 is moved upwards continuously, the swinging arm 4 also lifts up.
The driving motor 5 drives the pulling wheel 47; the power supply of the motor is controlled with an electronic circuit. The sewing machine has a step motor, the rpm and direction of rotation of which are input to the electronic circuit; the circuit processes the aforesaid data and then generates an output which is fed in to the driving motor 5. This then drives the pulling wheel 47 at a suitable speed and direction in accordance with the speed and direction of the sewing machine; in other words, the pulling wheel 47 rotates in accordance with the speed of the sewing machine to pull the cloth material being sewed. Since the electronic control circuit maybe of a type well-known in the art, no further details of its theory and function are given.
The driving motor 5 is mounted on a motor frame 33; the axle of the motor 5 is mounted with a belt driven wheel 51. The driving wheel 51 and the driven wheel 52 on the axle 31 of the main support 3 comprise a first belt wheel assembly so as to transmit the power of the driving motor 5 to the axle 31.
The automatic adjustment feature of the present invention can adapt to any thickness variation of the cloth material on the sewing machine (as shown in
Figures 3 and 4), and this feature is achieved by means of the pivotal connection between the swinging arm 4 and the main support 3. When the thickness of the cloth material is increased, the pulling wheel 47 is pushed upwards against the downward pressure of the minor adjusting screw 321 to cause the swinging arm 4 to move upwards, and therefore the distance between the pulling wheel 47 and the needle plate becomes greater.
Therefore, the distance between the pulling wheel 47 and the needle plate can be adjusted automatically via the swinging arm 4 in accordance with the thickness of cloth material to be sewed; the pulling wheel 47 will accordingly apply a suitable pulling pressure to the cloth material so as to prevent creasing of the material.
Screws are preferably used to mount the apparatus of the present invention to a sewing machine, the screws attaching the fixing base 11 to the rear side of the sewing machine frame. The height of the main support 3 may be set by adjusting the position of the stop block 211 on the movable rod 21; as a result, the swinging arm 4 will also be moved by the main support 3 to change the distance between the pulling wheel 47 and the pressing foot. Therefore, the change in the height of the stop block 211 can change the position of the pulling wheel 47 so that the apparatus of the present invention can be adapted to various models of sewing machines.
Since the swinging arm 4 can swing up and down a given small angle, a suitable distance must be maintained between the pulling wheel 47 and the pressing foot so as to prevent the pressing foot from hindering the upwards movement of the pulling wheel. A maximum thickness of a cloth material may be used in a sewing machine with the present invention by adjusting the distance between the stopping screw 322 and the swinging arm 4; moreover, when the pressing foot is raised (when changing the sewing direction, the pressing foot has to be lifted to move the cloth material), the stopping screw 322 can also provide a second lifting movement of the whole device; in other words, when the pressing foot is to be lifted up, the swinging arm 4 will also be lifted up as a result of the guide fork 48 (as shown in
Figure 6).When the pressing foot is lifted up continuously, the swinging arm 4 is stopped by the stopping screw 322 when then swinging arm 4 has completed it first portion of movement. If the pressing foot is continuously raised, the swinging arm 4 causes the main support 3 to raise until the pressing foot reaches its top limit (determined by the stopping screw 322); this is the second portion of movement of the device. It is apparent that a device accordng to the present invention can not only have the main support 3 lifted up with itS own pulling handle 2112, but can also have the main support 3 lifted up by lifting up the pressing foot (when changing the sewing direction on a cloth material).The swinging arm 4 presses downwardly to provide the pulling wheel 47 with a downward pressing force to be applied to a cloth material being sewed,
The downward pressure of the swinging arm 4 is generated by means of a small adjusting screw 321 so that the pulling wheel 47 applies a pressure to the cloth material being sewed,
Briefly, since the swinging arm 4 and the main support 3 are pivotally connected, the device has an automatic adjustment functioh whereby it can adapt to the thickness of various cloth materials; this feature is not taught by any sewing machine. However, the description and the accompanying drawings merely illustrate embodiments of the present invention; any person skilled in the art may devise modifications or changes, such as changing the transmission structure of the belts or the gears, which are deemed within the spirit and scope of the present invention claimed.
