摘要： An acoustical shield assembly and mating thread preguide unit include a series of acoustically insulated panels that substantially surround a sewing machine so as to be operative in attenuating any generated noise. A portion of the top panel, including a downwardly extending flange, is hinged to move between an opened position allowing access to the sewing machine and a closed position for mating with the preguide unit. The preguide unit is mounted to the sewing machine by a pair of adjustable mounting rods and includes two face plates spaced apart by means of a pair of spacer posts. Each face plate includes eyelets between the spacer posts for the passage of thread to the sewing machine. When the hinged portion of the top panel is closed, an elongated opening is formed between the downwardly extending flange and the top edge of the adjacent rear side panel of the shield assembly. The preguide unit is received in the opening with bearing surfaces of the spacer posts engaging both the downwardly extending flange and top edge of the rear side panel. The spacer posts serve to seal the ends of the elongated opening. Additionally, the exterior surface of the inner face plate seals against the interior surfaces of the downwardly extending flange and rear side panel adjacent the opening to provide maximum sound attenuation.
摘要翻译： 声屏蔽组件和配合线前导单元包括基本围绕缝纫机的一系列隔音面板，以便可以衰减任何产生的噪声。 顶板的一部分，包括向下延伸的凸缘，铰接在允许进入缝纫机的打开位置和用于与前导单元配合的关闭位置之间移动。 前置单元通过一对可调安装杆安装在缝纫机上，并且包括通过一对间隔柱隔开的两个面板。 每个面板在间隔柱之间包括用于使线通过缝纫机的孔眼。 当顶板的铰接部分关闭时，在向下延伸的凸缘与屏蔽组件的相邻后侧板的顶部边缘之间形成细长的开口。 前导单元被容纳在开口中，间隔柱的轴承表面接合后侧板的向下延伸的凸缘和顶部边缘。 间隔柱用于密封细长开口的端部。 此外，内表面板的外表面密封靠近开口的向下延伸的凸缘和后侧板的内表面，以提供最大的声音衰减。

摘要： The sewing machine has flaps hinged to the frame forming a carrying case therewith and are foldable downwards to form a worktable. The flaps are hinged along the base of the machine and are in two portions with connecting hinges enabling the outer edges of the flaps to rest on the base clear of the free arm. The connecting hinges have two hinging axis positions laterally separated and parallelly separated by a slideway, enabling the flaps to form a worktable either flush with the top surface of the free arm or below and clear of the latter. A lug holds the two portions blocked for the packing position of the flaps. A front flap may be one piece or of two hinged portions and attached to the front edge of the base.
摘要翻译： 缝纫机具有铰链到框架上的折板，形成一个便携箱，并可向下折叠以形成工作台。 翼片沿着机器的基部铰接，并且具有连接铰链的两部分，使得翼片的外边缘能够靠在自由臂上的基座上。 连接铰链具有两个横向分离的铰接轴位置，并且由滑道平行地分开，使得翼片能够形成与自由臂的顶表面齐平的下方的工作台，或者与后者相交。 凸耳保持两个部分被挡住，用于襟翼的包装位置。 前挡板可以是一个或两个铰接部分，并且连接到基座的前边缘。
