Abstract: This invention relates to a combined surface treating and polishing and suction cleaning apparatus having rotatable brushes movable over a surface. A movable control shutter in a first position covers an opening in the air passageway of the suction cleaning component of the apparatus so that it will operate properly as a suction cleaner. When the control shutter is in its first position mechanism for dispensing liquid wax from a container onto the surface is rendered inoperable. When the control shutter is in its first position a vessel for holding a body of liquid treating agent cannot be removably mounted on the apparatus for dispensing such liquid onto the surface. In the second position of the control shutter the opening in the passageway of the suction cleaning component is uncovered so that atmospheric air will be drawn into the air passageway by a fan and the apparatus cannot operate properly as a suction cleaner. When the control shutter is in its second position the mechanism for dispensing liquid wax from its container is rendered operable. When the control shutter is in its second position the vessel for the liquid treating agent can be removably mounted on the apparatus for dispensing such agent onto the surface. The mechanism for dispensing wax from its container and the mechanism for dispensing liquid treating agent from the vessel include parts which are common to both mechanisms, such parts operating in one way to dispense liquid wax from its container when the vessel for liquid treating agent is not mounted on the apparatus and operating in another way to dispense liquid treating agent from the vessel when it is mounted on the apparatus.

Abstract translation: 本发明涉及一种组合的表面处理和抛光和抽吸清洁装置，其具有可在表面上移动的旋转刷。 在第一位置的可移动控制闸板覆盖设备的抽吸清洁部件的空气通道中的开口，使得其将作为抽吸清洁器正常工作。 当控制闸板处于用于将液体蜡从容器分配到表面上的第一位置机构使得不可操作时。 当控制挡板处于其第一位置时，用于保持液体处理剂体的容器不能可拆卸地安装在用于将这种液体分配到表面上的装置上。 在控制快门的第二位置，抽吸清洁部件的通道中的开口未被覆盖，使得大气通过风扇被吸入空气通道中，并且该装置不能作为抽吸清洁器正常工作。 当控制挡板处于其第二位置时，用于从其容器分配液体蜡的机构可操作。 当控制挡板处于其第二位置时，用于液体处理剂的容器可拆卸地安装在用于将这种试剂分配到表面上的装置上。 用于从其容器分配蜡的机构和用于从容器分配液体处理剂的机构包括两种机构共同的部件，这些部件以一种方式操作，以便当液体处理剂的容器不是从其容器分配液体蜡时 安装在设备上并以另一种方式操作，以便当其安装在设备上时从容器中分配液体处理剂。

Abstract: THIS INVENTION RELATES TO EQUIPMENT FOR INDICATING A PREDETERMINED PRESSURE DIFFERENTIAL BETWEEN GASEOUS FLUIDS AT LOW AND HIGHER PRESSURES. A HOLLOW SLEEVE OF CONICAL FORM HAS AN INNER TAPERED WALL. THE LARGE END OF THE HOLLOW SLEEVE IS IN COMMUNICATION WITH THE GASEOUS FLUID AT THE HIGHER PRESSURE AND ITS SMALL END IS IN COMMUNICATION WITH THE GASESOUS FLUID AT THE LOW PRESSURE. A MOVABLE MEMBER OF CONICAL FORM, WHICH HAS A TAPERED OUTER WALL, IS DISPOSED WITHIN THE HOLLOW SLEEVE WITH THE SMALL END OF THE MEMBER AT THE SMALL END OF THE SLEEVE. THE MEMBER, WHICH IS SPRING BIASED FROM THE SMALL END OF THE SLEEVE, HAS A SIGNALLING SYSTEM PART MOUNTED THEREON. THE PART AND MEMBER ARE IN ONE POSITION WITH RESPECT TO THE SLEEVE WHEN THE PRESSURE DIFFERENTIAL BETWEEN THE GASEOUS FLUIDS IS LESS THAN A PREDETERMINED VALUE AND IN A SECOND POSITION WITH RESPECT TO THE SLEEVE WHEN THE PRESSURE DIFFERENTIAL BETWEEN THE GASEOUS FLUIDS IS AT THE PREDETERMINED VALUE. THE RELATIVE POSITION OF THE PART AND MEMBER WITH RESPECT TO THE SLEEVE IS DEPENDENT UPON THE VELOCITY OF AIR FLOWING FROM THE LARGE TO THE SMALL END OF THE SLEEVE THROUGH A GAP BETWEEN THE SLEEVE AND MEMBER. THE PART IN ITS SECOND POSITION SIGNALS THAT THE PRESSURE DIFFERENTIAL BETWEEN THE GASEOUS FLUIDS IS AT THE PREDETERMINED VALUE.
