DETAILED DESCRIPTION OF THE DRAWINGS

(16) For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.

(17) An illustrative embodiment of a sewing machine assembly 10 is shown in FIGS. 1 and 2. The sewing machine assembly 10 is configured change between a fixed motion mode as shown in FIG. 2 and a free motion mode as shown in FIG. 9.

(18) In the free motion mode, a user is able to freely maneuver the sewing machine assembly in lateral and longitudinal directions. The fabric remains in place, while the sewing machine is moved relative to the fabric to sew the fabric. This allows the user to create intricate patterns with the stitching.

(19) In the fixed motion mode, the sewing machine is fixed in place and the fabric is feed through the sewing machine to sew the fabric. In the fixed motion mode, a feed dog assembly may be used to pull the fabric through the sewing machine.

(20) Typically, a sewing machine is only operable in one of the free motion mode or the fixed motion mode. The user would then need to switch between different machines depending on the desired stitching.

(21) Therefore, the sewing machine assembly 10 is convertible between the free motion mode and the fixed motion mode as shown in FIG. 9. The sewing machine assembly 10 includes a feed dog assembly 14 that includes a feed dog mounted to the sewing machine frame 12 to reciprocate horizontally relative to the sewing machine frame 12 to pull the fabric therethrough when the sewing machine assembly 10 is in the fixed motion mode.

(22) However, a hopping foot is commonly used in the free motion mode, while a presser or walking foot is used in the fixed motion mode. The hooping foot may provide a substantially unobstructed view of the fabric compared to the presser foot when the user desires to create intricate patterns with the stitching. Additionally, the presser foot may need to align with the feed dog as the feed dog and presser foot work together to pull the fabric through the sewing machine.

(23) The sewing machine assembly 10 has a sewing machine frame 12, a feed dog assembly 14, a needle bar 16, a main presser bar 18, and a presser foot assembly 20 that allows the user to switch between a hopping foot and a presser foot as shown in FIGS. 1-9. The feed dog assembly 14 has the feed dog 30 mounted to the sewing machine frame 12 to reciprocate horizontally relative to the sewing machine frame 12. The needle bar 16 is attached to a frame head 28 of the sewing machine frame 12 and configured to linearly reciprocate relative to the frame head 28 along a needle bar axis 16A. The main presser bar 18 is attached to the frame head 28 of the sewing machine frame 12 and extends toward a frame base 24 along a main axis 18A.

(24) The presser foot assembly 20 is configured to be changed between an unused configuration associated with the free motion mode of the sewing machine assembly as shown in FIG. 8 and an in-use configuration associated with the fixed motion mode of the sewing machine assembly as shown in FIG. 2. In the unused configuration, the presser foot assembly 20 is spaced apart from the main presser bar 18. In the in-use configuration, the presser foot assembly 20 is coupled to the main presser bar 18. This allows the user to go back and forth between the free motion mode and the fixed motion mode.

(25) The presser foot assembly 20 includes an auxiliary presser bar 40, a presser foot 42, and an auxiliary presser bar mount 44 as shown in FIGS. 2-9. The auxiliary presser bar 40 extends along an auxiliary axis 40A between a first end 48 and a second end 50 spaced apart axially from the first end 48. The presser foot 42 is coupled to the first end 48 of the auxiliary presser bar 40. The auxiliary presser bar mount 44 is coupled to the second end 50 of the auxiliary presser bar 40.

(26) The auxiliary presser bar mount 44 is configured to be selectively coupled to the main presser bar 18 as shown in FIG. 9. The auxiliary presser bar mount 44 selectively couples to the main presser bar 18 to couple the presser foot assembly 20 to the main presser bar 18 in the in-use configuration to align the presser foot 42 with the feed dog. The auxiliary presser bar mount 44 offsets the auxiliary presser bar 40 from the main presser bar 18 to align the presser foot 42 with the feed dog on the frame base 24.

(27) Turning again to the sewing machine frame 12, the sewing machine frame 12 includes the frame base 24, a frame body 26, and the frame head 28 as shown in FIG. 1. The frame body 26 extends from the frame base 24.

The feed dog assembly 14 includes the feed dog 30, a feed dog drive system (not shown), and a feed dog cover 32. The feed dog drive system is configured to drive reciprocating movement of the feed dog 30 relative to the frame base 24. The feed dog cover 32 is configured to be selectively coupled to the frame base 24 to change the sewing machine assembly 10 between the free and fixed motion modes.

(29) The needle bar 16 is attached to the frame head 28 of the sewing machine frame 12 as shown in FIGS. 2 and 5-7. The needle bar 16 is configured to linearly reciprocate relative to the frame head 28 along a needle bar axis 16A. A needle 16N is coupled to the needle bar 16.

(30) The main presser bar 18 is mounted to the frame head 28 as shown in FIGS. 2 and 5-7. The main presser bar 18 extends from the frame head 28 toward the frame base 24. In the illustrative embodiment, a hopping foot 22 is configured to be selectively coupled to a terminal end 18T of the main presser bar 18 in an in-use position when the presser bar assembly is in the unused configuration so that the sewing machine assembly is in the free motion mode.

(31) The presser foot assembly 20 includes the auxiliary presser bar 40, the presser foot 42, the auxiliary presser bar mount 44, and a bias element 46 as shown in FIGS. 2-9. The bias element 46 is arranged in a presser bar hole 58 formed in the auxiliary presser bar mount 44. The bias element 46 is arranged in the presser bar hole 58 to extend between the auxiliary presser bar mount 44 and the second end 50 of the auxiliary presser bar 40 to apply a bias force to the auxiliary presser bar 40 to urge the presser foot 42 toward the frame base 24 of the sewing machine frame 12.

(32) The auxiliary presser bar mount 44 includes a mount body 52, a mount arm 54, and a fastener 56 as shown in FIGS. 3-8. The mount body 52 defines the presser bar hole 58 configured to receive the second end 50 of the auxiliary presser bar 40. The mount arm 54 extends from the mount body 52 toward the main presser bar 18 at an angle relative to the mount body 52. The mount arm 54 defines a presser bar groove 60 configured to receive the terminal end 18T of the main presser bar 18. The fastener 56 extends into the mount arm 54 and the main presser bar 18 to couple the presser foot assembly 20 to the main presser bar 18.

(33) In the illustrative embodiment, the angle of the mount arm 54 relative to the mount body 52 corresponds to the offset of the feed dog 30 relative to the main presser bar 18. The angle of the mount arm 54 relative to the mount body 52 is about 90 degrees in the illustrative embodiment.

(34) The mount body 52 includes a housing member 62 and a cover plate 64 as shown in FIGS. 3 and 4. The housing member 62 is formed to define the presser bar hole 58. The cover plate 64 is coupled to the housing member 62 to close a portion of the opening to the presser bar hole 58. The cover plate 64 has a through hole 64H that receives the auxiliary presser bar 40. Fasteners 66 extend through the cover plate 64 into the housing member 62 to couple the cover plate 64 to the housing member 62 in the illustrative embodiment.

(35) The auxiliary presser bar 40 is formed to define a shoulder surface 68 as shown in FIGS. 4 and 7. The bias element 46 engages the shoulder surface 68 to apply the bias force to the auxiliary presser bar 40.

(36) In the illustrative embodiment, the auxiliary presser bar 40 includes a rod 70 with a lip 72 as shown in FIGS. 4 and 7. The rod 70 extends along the auxiliary axis 40A. The lip 72 extends circumferentially around the rod 70 and radially outward from the rod 70 to define the shoulder surface 68. The bias element 46 extends around the rod 70 and engages the shoulder surface 68 defined by the lip 72 to apply the bias force to the auxiliary presser bar 40.

(37) In some embodiments, the rod 70 and the lip 72 are a single integral component. In the illustrative embodiment, the lip 72 is a washer 72 coupled to the rod 70. The washer 72 is arranged around the rod 70 and a peg 74 extends through the rod 70 to couple the washer 72 to the rod 70. The peg 74 blocks the movement of the washer 72 relative to the rod 70.

(38) In the illustrative embodiment, the main presser bar 18 has a first axial length 18L and the rod 70 of the auxiliary presser bar 40 has a second axial length 70L as shown in FIGS. 4 and 7. The second axial length 70L of the auxiliary presser bar 40 is less than the axial length 18L of the main presser bar 18.

(39) The presser foot 42 has a lead edge 76 and a trailing edge 78 as shown in FIGS. 3 and 4. The trailing edge 78 is spaced apart horizontally from the lead edge 76. The presser foot 42 is aligned with the feed dog 30. The presser foot 42 may also be configured to be selectively coupled to the first end 48 of the auxiliary presser bar 40 as shown in FIG. 4.

(40) In the free motion mode, a hopping foot may be selectively coupled to the main presser bar 18. However, in the fixed motion mode, the presser foot assembly 20 is coupled to the main presser bar 18.

(41) A method of using the sewing machine assembly 10 may include several steps. The method may begin with the sewing machine assembly 10 in one of the free motion mode and the fixed motion mode. The user may desire to switch the sewing machine assembly 10 to the other mode.

(42) To switch the sewing machine assembly 10 from the fixed motion mode to the free motion mode, the user begins by changing the presser foot assembly 20 from the in-use configuration to the unused configuration as shown in FIG. 9. To change the presser foot assembly 20 from the in-use configuration to the unused configuration, the user removes the fastener 56 from the auxiliary presser bar mount 44 and the main presser bar 18 so that the presser foot assembly 20 is free to move away from the main presser bar 18. The user then spaces the presser foot assembly 20 away from the main presser bar 18.

(43) After the presser foot assembly 20 is in the unused configuration, the user may change the hopping foot 22 from the unused configuration to the in-use configuration as shown in FIG. 9. The user may use the fastener 56 to couple the hopping foot 22 to the main presser bar 18. Additionally, a feed dog cover 32 may be placed over the feed dog 30 to cover the feed dog 30 as show in FIG. 9.

(44) To switch the sewing machine assembly 10 from the free motion mode to the fixed motion mode, the steps are repeated in reverse. The user may remove the feed dog cover 32 and move the hopping foot 22 to the unused configuration so that the presser foot assembly 20 may be coupled to the main presser bar 18.

(45) In some embodiments, instead of changing the presser foot assembly 20 from the unused and the in-use configurations, the user may uncouple the presser foot 42 from the first end 48 of the auxiliary presser bar 40 and couple the hopping foot 22 to the first end 48 of the auxiliary presser bar 40. The feed dog cover 32 would be placed over the feed dog 30 if the hopping foot 22 is coupled to the auxiliary presser bar 40.

(46) Another embodiment of a sewing machine assembly 210 in accordance with the present disclosure is shown in FIGS. 10-15. The sewing machine assembly 210 is substantially similar to the sewing machine assembly 10 shown in FIGS. 1-9 and described herein.
