Patented Dec. 19, 1911'.
To all whom it may concern:
Be it known that I, Orro H. MOHR, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented new and useful Improvements in Vacuum Cleaning Apparatus, of which the following is a specification.
The invention relates to vacuum cleaning apparatus and particularly to a cleaning tool provided with a dirt receptacle for collecting and retaining the dirt and dust.
In the operation of vacuum cleaners in which the suction device is removed somewhat from the cleaning tool, much of the energy of the suction is lost in transporting the dust and dirt through the long length of hose and in the friction of the dust and as it passes through the hose.
In the present invention I contemplate separating thematerial carried by the air current, from the air at apoint on or in close relation to the cleaning tool, so that the material will be carried only a short distance by the air.
In carrying out my invention I preferably place a dirt receptacle on an extension of the cleaning tool constituting a handle and connect such receptacle to the handle in such a manner that all of the dirt laden air passing through the cleaning tool is diverted into the dirt receptacle. Inthe dirt receptacle between the inlet'and the outlet I arrange a screen or arresting. means so that the irt and dust is deposited in the receptacle and the air passes through. The receptacle is so arranged that it can be readily removed when it becomes full, so that the dirt may be emptied. A The object of the invention is to provide a dirt receptacle on the cleanin tool adapted to retain all of the dirt raised, so that the loss'of energy due to the carrying of the dirt through the long conductor to the suction means is obviated.
With this and other objects in view, as Will more fully hereinafter appear, the invention consists of certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it be ing understood that various changes in the form, proportion, size and minor details of Referring to the drawings,

comprises the usual head having therein the be tubular and are shown as being connected with the usual flexible or other conduit leading to the suction means. and 12 constitute a handle for moving the tool about a floor, or other. surface to be cleansed. The dirtreceptacle 15 is attached to the air-line,.between the suction means and the inlet 2 of the cleaning tool in close relation to the cleaning tool. The receptacle is preferably located on the handle. The cleaning tool or the handle is connected to any suitable suction means, not shown in the drawings, by a single conductor through air is drawn. The material removed from the floor or other surface by the air is, therefore, carried only a short distance and deposited in the dirt receptacle and the energy of the suction is not absorbed by carrying the material through the conductor.
It is evident that when a long conductor connects the cleaning tool with the suction sumed in carrying the material through the conductor and in the friction of the material in the conductor. By the use of the present invention, however, all of the coarser material is removed from the conductor at a point near the cleaning tool, thereby greatly increasing the efficiency of the cleaning apparatus.
The coupling 4 for connecting receptacle with the air line consists of the elbow 5 havingtwo passages 67 extending therethrough. he passages are separated from each other by the central rib 8 Figure 1 is a and 12 which may.

dirt laden air therefore enters the dirt re- The passage 6 is contacle through other circumstances, I provide a guard ceptacle through passage 6 and passes out through passage 7 when the dirt has been removed. A circular plate 13 having a depending flangel is provided on the lower end of the elbow and preferably integral therewith. The dirt receptacle 15 is preferably cylindrical in shape and is provided with a screw thread at its open end to enage a similar thread on the depending ange 14. A washer or packing ring 16 is generally provided 15 and the plate 13 joint. A tube 17 extending into the receptacle is secured in passage 6 for conveying the dirt carrying air to the lower part of the receptacle. The outlet from the recepthe passage 7 is covered by a screen 18 to prevent the dirt from assing out of the chamber. The screen 18 is made of larger superficial area than the area of the outlet to increase the efiiciency of its action. In the drawings I have shown the screen 18 to be cylindrical in shape, closed at bottom and top except at the offset por-' tion where it is attached to the ferrule 19 which fits the passage 7 It is to be understood, however, that the screen could be made in other forms and receptacle between the inlet and the The receptacle 15 is preferably made of.

When an amount of dirt has been collected in the receptacle, it is unscrewed from the cap 13, emptied, and screwed back into position. In the preferred construction, as shown in Fig. 1 of the drawings, the receptacle is, so ocated that it depends below the handle of the tool during the cleaning 0 eration and assumes a more or less incline position, so that the dirt tends to gravitate to the lowest part of the rece tacle and collect below the screen 18 and inlet pipe 17. The screen 18, is of sufliciently fine mesh to arrest ractically all of the dust or dirt during t e passage of air through the apparatus, and the receptacle is of course removed and the dirt emptied before it rises high enough in the between the receptacle. to form an air tight adapted to serve as a To prevent injury to ceptacle', and arranged to receptacle to interfere with the tree passage of the air.
