Application filed Inne2, 1927. Serial No. 195,944.
This invention relates to suction cleaner heads or tools, and while not limited thereto,
relates more particularly to a suction cleaner tool or head particularly designed: for cleaning irregular surfaces such as the slotted floors of railway cars and the like, and due to its novel contour said tool is also particularly adapted to cleaning in corners andunder low lying objects such as seats of railway cars and the like.
Another object of the present invention is i to provide a tool of this class having a brush three equalsides so that the brush may be removed and turned when its nose-point becomes worn, to present anotherof its three points, thereby permitting even wearing of the brush and greatly increasingits life.
Astill further object is to provide a novel means for securing the head or .tool to the suction tube of the cleaner which is simple in design and eflective in operation.
In the drawings- Figure 1 is a plan view of a tool constructed in accordance with my invention.
Figure 2 is a sectional elevation on the line II-r-II of Figure 1.
Figure 3 is a fragmentary sectionalelevation on the line III-.-III of Figure 1.
The cleaning head A of this invention; comprises a metallic body portion substantially 5 triangular in plan and composed of a relatively flat top wall 3 and 11. depending peripheral 'flange' i. The wall 3 and flange 4 are formed integral and combine to form a tri-' angular shaped receivingsocket having three equal sides and adapted to receive a triangular brush member B.
The top wall 3 of the body portion of the cleaning head is provided with a centrally arranged opening 5 which communicates with 4 a suction conduit stub 6 formed integral with the top wall of thehead A, and adapted to be secured to the end of the suction conduit or tube 2 of a suction cleaning apparatus.
The conduit stub 6 is of slightly greater diameter than the suction tube 2 of the cleaner so as to telescopically receive the end of the tube 2. The stub 6' is: slotted longitudinally,
as at 7 from it's free end inwardly for a portlon 0t its length and is also slotted circuinferentially, as at 8, from the 'slot" 7 for approximately one-quarter of its circumference,
the slots 7 and 8 intersecting and outlining a depressing or contracting tongue portion 9 in the side wall of the conduit stub 6 adapted to be contracted against the tube 2 and frictionally secure the head A on said tube. A
lug 10 is formed integral with the tongue.
The brush B comprises a rigid triangularly shaped body portion 15 preferably composed of wood and which has its lower or bottom face cut away around its edge to form an annular horizontal flange portion 16 in which two or more rows of bristles 17 are'mounted in the usual manner.
The interior of the brush liody, thatis, that portionwithin or surrounded by the bristles '17, due to the cutting away of the body to form the flange 16, projects downwardly a material distance along the inside of the bristles 17 for apurpose to bedescribed.
The interior of the brush body is cut away to form a substantially triangular hollow suction dom'e 18 which terminates at its upper' end in a circular outlet opening 19 which communicates through the opening 5 in the body of the headA with the suction conduit stub 6. Theside walls of the dome 18 are inclined or flanged outwardly at a materially greater degree at'the points of the dome 18 than intermediate such points, so as to more evenly distribute the suction throughout the dome,
The brush B is adapted to be remoiiably secured in the head A byv screws 20 which pass through openings in the top wall 3 of thehead A and are threaded into the body of the brush B. 1
The interior portion ofthe brush body 15 which projects downwardl along the bristles 17 serves as a shield or s 'rt to deliver the suction forces closer' to the article being cleaned, while the bristles are free to flex out-.-
wardly.
The point. of the suction head opposite toefiiciency becomes lessened and a. new nose point is necessary. Due to the novel shape of the cleaning head and brush, when the nose point of the brush becomes worn, it isonly necessary to remove the screws and remove the brush from the head A, then rotate the brush one-third a revolution so as to locate one of the other points of the brush at the nose point of the head and then remount the brush. The above operation may be repeat ed until all of the three points of the brush have become worn, and results in a materially longer life of the brush and also, in a more even wearing of the brush.
The bristles of the brush B are of material length so as to extend into the slots or depressions in the 'floor of a railway car or similar structure. It is well known that the slotted floors of railway cars and the like hecome partly, and sometimes wholly, filled .with dirt and foreign matter carried into the cars by passengers. The brush of the present invention will loosen the foreign matter and when pressed into the slots or depressions, serves as a flexible skirt to cause the in the cleaning head so that a stron suction is had to liftthe heavy particles 0 foreign matter out of the grooves of a car floor.
While I have shown and described one specific embodiment-of my invention, it will be understood that Ido not wish to be limcomposed of a relatively fiat top wall and a depending peripheral-flange, which wall and flange combine to form a triangular receiving socket having substantially three equal sides to receive a triangula shaped brush member, said top wall of said body portion being provided with a centrally arranged f openmg communicating with an integrally formed connecting conduit adapted to be connected to the suction conduit of a cleaning apparatus, said'brush comprisin a substantially triangular rigid body portion adapted to fit within said body ortion of said head,
a row of bristles secure in and adjacent the outer ed e of said body portion of said brush, the portion of said brush bod within said bristles extending downward y amaterial distance along and terminating short of the lower ends of said bristles and having its cen tral portion cut away so as to form a skirt flange within said row f bristles and a hol-' low suction dome terminating in a centrally arranged opening communicating with the opening-in said top wall of said body portion of said head, and means for removably securing said brush in said body portion of said suction forces to be confined to the area withh ead.
In testimony signed my name.
