CLEANER osisme,
Original application filed April 12, 1919, Serial No. 289,617. Divided and this application filed March 24:,
' 1920. Serial No. 368,249.
To all-whom it may concern: Be it known that 1', JAMES B. KIRBY, :1 citizen of the United States, residing at I Cleveland, in the county of Cuyahoga and .5 State of Ohio,.have invented a certain new and useful Improvement in Cleaner Casings, of which the following is a full, clear, and
j j .exactdescription, reference being had to the-accompanying drawings.
This'inve'ntion relates to suction sweepers and especially to a sweeper of the type shown in my Patent No. 1,157,288, issued February 21, 1918, and in my application filed April 12, 1919, Serial No. 289,617, of
which the present case is a division. The
objects of the invention are the provision of a new, improved, and simplified device of this character which may be made from sheet metal and from a minimum number of parts; the provision of a suction sweeper casmg of strong and rigid construction which is susceptible of cheap and'rapid manufacture; while further objects and advantages will become apparent as this description proceeds.
In the drawings accompanying and forming a part of this application, Ihave shown one embodiment of my invention in which Fig. l'is asideelevation and Fig. 2 a central sectional view of my improved casing (the .30 carryingand operating means being. shown phantom); Fig. 3 isa sectional view corresponding to the broken line 3-3 of Fig. 2; and Fig. 4 is a perspective View of the fan casing alone priorto assembly;
In, its preferred form my improved casing consistsof three parts which Idenomi nate the fan chamber, nozzle, and dust-pan. The fan chamber is made from a flat sheet of metal by drawin the same into pocket form, and in itspr ferred construction has a U-shaped side wall comprising a pair of straight portions 11 connected together by a curved portion 2, the margins of the side wall being connected by flat walls and 4 respectively. This forms a pocketshaped chamber having its square end open as shown in Figs. 3 and 5, in addition to which the sides 3 and 4 are formed with circular openings 5 and 6 respectively. The open end of said chamber is formed with an oiltturned shoulder 7 surrounded by a rim 8, thus producing a rectangular recess which surrounds the entire device.
The collecting nozzle overlaps the top of said chamber and is preferably of a flaring or fan shape, its narrowest part surrounding and enclosing the opening5, and
its body broadening with increased distance from said opening to its forward extremity Where it projects beyond the limits of. said fan chamber. This nozzle has a body portion 10 and side--walls'11-11 which meet the top 3 of the fan chamber substantially perpendicularly, said walls having at their lower margin an inturned lip12 which extends in an-unbroken plane entirely around is bent to form a cylindrical segment 15,
whose end walls are bent downwardly to constitute ears 14-14 which extend beyond the plane defined by the lip- 12. I
The cylindrical segment 15 terminates-in a straight depending lip 16 which constitutes one side of the inletv mouth, while the cars 14, 14 terminate flush therewith as shown at 17, 17 to form the ends of said mouth.
The dust pan consists. of a single, approxi-f 4 mately triangular sheet of metal having the portion adjacent to one of its edges depressed to form a receiving ledge 18 and the other two edges left in the same plane as shown at 19 to interlock with the bead 14. The apex of the angle defined between the two last mentioned sides is cut away upon the arc of a, circle as shown at 20 so as to register with the aperture 5, the dust pan and nozzle being fitted together in such wise that the portion 20-of the one and the lip 12 of the other constitute substantially'a circle of the same diameter as that aperture. A- sheet metal neck-piece 21 passes through this aperture'and is flanged outwardly at each end so as to clamp the three parts together.
- The depressed portion of the dust pan is connectedwith the undeflected portions by inclines whose slope varies at different points, being greatest at the middle oint 22 where the distance between the le ge and the fan chamber is smallest and least at the points 23, 23 where this distance is greatest. The forward margin of this ledge portion is turned upwardly to form a flange 24 which .is parallel to the lip 16 and constitutes one side of the inlet mouth, while the ends of the ledge portion are formed with integral upturned ears 25, 25 which fit'inside and are secured to the ends 14, 14 by rivets 26.
It will thus be seen that the entire casing is made from three pieces of sheet metal stamped or drawn to the requisite fornnand secured'together by the seam 14, neck 20 and rivets 2626. The portion of the nozzle defined by the cylindrical segment 15 which constitutes a brush chamber, and the brushing mechanism may be of any suitable or desired type as also may the operating mechanism. The latter preferably comprises a suitable fan 31 mounted in thei'an chamber and driven from the carrying wheels 32 through the instrumentality of suitable gearing located inside a housing 33 secured to the bottom of the fan chamber, said wheels serving to support the fan chamber, at an oblique angle to the horizontal with its open end elevated, all as described and claimed in my patents and applications hereinbefore identified.
, It will be understood that many changes in shape and detail of construction can be made within the scope of my invention which is defined in theclaims hereto annexed.
Having thus described my invention, what I claim is X 1. In a casing for suction sweepers, a collecting nozzle, a dust pan and a fan chamber, the nozzle and dust pan being each made of a single piece of approximately triangular sheet metal joined together at two of their edges, theremaining edges being bent one downwardly and the other upwardly and spaced apart to define an inlet mouth, the apices of the edges which are joined together being rounded in opposite directions to define an opening and said fan chamber having an opennig registering therewith.
