Abstract: An embroidery machine includes an outer ring, an inner ring, a pair of screw mounts, a lever, a nut, and an adjusting screw. The outer ring includes a dividing portion. The inner ring and the outer ring holds a workpiece therebetween. The screw mounts are disposed at the dividing portion to oppose each other. The lever is disposed at one of the screw mounts and rotatable about a rotation axis. The nut is slidably held in the lever at a position eccentric from the rotation axis. The adjusting screw is mounted across the screw mounts and threadedly engaged with the nut. A shortest distance between a first surface of the one of the screw mounts and the nut is defined as a specific distance. The specific distance when the lever is at a second position is longer than the specific distance when the lever is at a first position.

Abstract: A presser device includes an attachment body, an adjustment member, and a presser body. The attachment body includes an attachment portion and a shaft. The attachment portion is attached to a presser bar included in a sewing machine and extending in a first direction. The shaft extends in a second direction that intersects the first direction. The adjustment member is configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction. The presser body includes an insertion hole and an insertion portion, the insertion hole penetrating in the first direction. The insertion portion is configured such that the shaft is inserted therethrough. The presser body is configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member.

Abstract: An embroidery frame includes a mounting portion to be mounted on a sewing machine and a frame portion. The frame portion has a first frame, a hinge portion, a second frame, a first clamping portion, and a second clamping portion. The first frame is connected to the mounting portion. The hinge portion is connected to one end of the first frame. The second frame is connected at one end to the hinge portion such that the second frame is able to rotate with respect to the first frame. The first clamping portion is configured to clamp the first sewing object together with the first frame while the second frame is open with respect to the first frame. The second clamping portion is configured to clamp the second sewing object together with the second frame while the second frame is open with respect to the first frame.

Abstract: A sewing machine includes a first thread spool base having a first thread spool pin and a first guide member, and a second thread spool base having a second thread spool pin and a second guide member. The first thread spool pin is inserted into a through hole of a thread spool. The first guide member has a first thread guard portion that guides a needle thread delivered from a thread spool mounted on the first thread spool base to the sewing machine. The second thread spool base can be attached to and removed from the first thread spool base. The second thread spool pin is inserted into a through hole of the thread spool. The second guide member has a second thread guard portion that guides a needle thread delivered from the thread spool mounted on the second thread spool base to the sewing machine.

Abstract: A container includes a cover body and a holding body, and is removably mounted on a needle plate of a sewing machine including a horizontal shuttle. The horizontal shuttle includes an inner shuttle that includes a bobbin containing portion. The cover body is plate-shaped, is removably mounted in the needle plate in a position above the horizontal shuttle, and includes a through-hole and a first face that occupies the same plane as a top face of the needle plate when the cover body is mounted in the needle plate. The holding body is disposed inside the bobbin containing portion and includes a side wall and a bottom wall. The side wall encircles an area of a second face in which the through-hole is formed. The second face is a face on the opposite side of the cover body from the first face. The bottom wall is opposite the second face.
