    • Hoop propelling trundle comprising a handle with a normally closed loop on one end thereof having relatively spreadable resilient legs for forming an opening through which a hoop may be passed to secure it to or detach it from the loop. A bight is provided for engaging the hoop for propelling it and another bight or hook is provided for arresting its rolling motion. In one species, the two bights lie in the same plane and in another species they lie in angularly related planes. A slidable clip on the handle secures the hoop thereto with the handle disposed substantially in the plane of the hoop.
    • 环形推进桁架包括在其一端具有常闭环的手柄,其具有用于形成开口的相对可展开的弹性支脚,通过该开口可以通过箍以将其固定到环或将其从该环脱离。 提供用于接合环以推动它的弯头,并且提供另一个弯针或钩以阻止其滚动。 在一种物种中,两只蝙蝠位于同一平面上,另一种是位于角度相关的平面上。 手柄上的可滑动的夹子将手柄固定到其上,手柄基本上设置在箍的平面内。

    • A one-piece baffle member for use in the heat tubes of a horizontal fire tube boiler for spanning a part of the crosssectional area of the heat tubes in the portion thereof to which the heating medium normally gravitates to encourage deflection of the heating medium to a portion of the tubes to which it does not normally gravitate. The baffle member is stamped from generally flat sheet metal material having an elongated body portion extending longitudinally of a heat tube generally in the area of a diameter thereof, with a baffle portion bent upwardly from one end of the body portion extending transversely of the heat tube spanning the top portion of the heat tube. Feet portions are bent downwardly from the body portion for engaging the lower inside surface of the heat tube affording the sole support of the baffle member in the heat tube. The disclosure includes a method of fabricating the baffle member by stamping a blank therefore from a strip of sheet metal material.
    • 一种用于水平火管锅炉的热管中的一体式挡板件,用于跨越加热介质通常重力加热的部分的热管的横截面积的一部分,以促进加热介质的偏转 到其通常不会引力的管的一部分。 挡板构件由大致平坦的金属板材冲压成具有细长主体部分,该细长主体部分通常在其直径区域的热管的纵向延伸,挡板部分从主体部分的一端向上弯曲,该主体部分横跨热管延伸 跨越热管的顶部。 脚部从主体部分向下弯曲,用于接合热管的下内表面,从而在热管中提供挡板构件的底部支撑。 本公开内容包括通过从金属片材料冲压坯料来制造挡板构件的方法。
