(Cl. 183e-371);

This invention' relates to* aA suction cleaner i and more particularly to the constructionof'the casing' fora tank typecleaner:

It' is an object of" the inventionto provide a newcand novel suction cleaner'casing.` Another object is to provide a cleaner casing having a skeleton frame to support the relatively heavy parts of the suction cleaner mechanism. A further object is to provide a skeleton frame-for a cleaner casing having a'cover therefor'ofmetallic and non-metallic materials. Another object of theinvention is to provide a cleanerv casing having a skeleton framek and a non-metallic'J cover therefor which is formed directly about the frame andiattached thereto. 4Other objectsfand advantages of the invention will be apparent fromV the following specification and drawings` wherein'z' Figure l is a sectional view ofjithev cleaner. cas;u 111g;

Figure 2 is a section along the lineA 22-2 in Figurel; Figure 3 is a section along 'theline' 3-3 in 'Fig'- ure `1;

Figure 41s a perspective'vlewf of' theskeleto frame construction; andl 1 Figure 5 is a perspective view of the casing with certain parts removed'.

The embodiment of the invention herein disclosed comprises a casing lil having a skeleton frame includingatop side member Il of channel shape and two angle shaped bottom side members' I2 and I3. Theforward ends ofthe side members lare welded to the wallsof recesses I4, l5, and |16 ina. flange Il of anV L.shaped front end member 'and'lie flush with the vertical Wall I9,

while the rear ends of the side members' extend beyond an L-shaped rear endmember 1Z0 andare secured thereto-in walls of recesses similar to those in the frontend member. Between theend members I 5 and 20 is a transverse member 22 which is secured to the side frame members Il, l2, and I3' and forms with-the end members the frame-structure for a motor-elflamberl 23- and4 a suction chamber 24. The cover for the skeleton frame includes a metallic bottom plate 25 having a flat portion 25 and-upstanding marginal flanges 21 and 28 to cover the area between the bottom side frame members I2 and I3 and the remaining portion of the frame is enclosed by a non-metallic cover 30. The cover 3i! is attached to the frame by heating a sheet of non-metallic'material and then placing it about the frame and forming it to the contour of the frame. Thereafter the marginal edges 3I-3l of the cover 30 are placed between the 2- side frame members IZ4 and` I3 andi thee bottom plate 25, and thelatterandthe-'cover 30.'.zanfeese-4 cured to the sideirame membersv |2- andi |3355 means'of apluralityof rivets 33.

The opposite ends of" the casing IllY areclosed by` a suction end cap havingganV inlet. 36, and by an exhaust end cap 31 having an outlets38; A1 suitable latch 39 removably attachesthe. end. cap 35 tothe casing I0, while the rear end: cap 31 is secured by a screw 40 threaded intoabracketilll carried by the top side member` Il, and? another screw 42 is threaded into a bracket43mounted in a recess 44 in the end frame member'20;

Disposed within the suction chamber-24.1 isla dirt lteringbag 45 supported at its'openzendby an annular flange 4B of a bag supportingringgslll which is securedto the front end member. I8` by unshown bolts extending-through openingsfISfin the; vertical' wall I9 offthefvfrontnendmember; The rear end of the bag 45 ist supportedghy a pluralityof'arms', two of'which are identifledat 5I and 52, and a'b'ail 53 connects the armti.` to abag shawing mechanism indicated' generally at 54 of the type disclosed in the' applicationl of' Louis E. Segesman, lserialN'o. 599,147; nlediJune 131l 1945 now PatentNo. 2,498,098. The:ln'agshak,

ingmechanlsm is actuated by'a manually-openated lever 55 which is pivotallyf-mountedi in: the

opening56 of the bottom plate.-

In operating the bag shaking mechanism, the front end cap 35 is removed'and.the=c1eanerfcasing is up-ended to place the vertical' wall' |9 of the-front end member I8 on asupportingfsurface, and a piece of paper'is-preferably placed beneath theend frame member |8'to collectrthefdirtrremoved from the bag. Pressure is applied.' tof the bag shaking lever to operate the bag shaking mechanismk 54 in the' manner described in said pending application and the dirt is removed'from the bag and drops onto the paper; During: the bag shaking operation thepedal 55 pivotsiin; the opening 5B of the metal coveriplatel 25' and' the forceAv applied toA the pedal'Y is A transmitted. toa the metal cover plate 25 so that theP non'fmetallic cover 30 is not' subjected to the rela-tively large force applied to thebagshaking pedal55;

Disposed in the motor chamber 23 isa motor.- fan unit 6E), the forwardend of -which seatszin a resilient ring 6| mounted upon the intermediate member 22. The rear end of the motor-fan unit is mounted in a resilient ring 63 which seats in a spider member 64 attached to the vertical wall 65 of the rear end member 20 by bolts extending through openings B6 in the vertical wall 65.

In attaching the intermediate member 22 and spider 64 to the side frame member Il, l2, and I3, the vibration of the motor-fan unit is not transmitted to the non-metallic cover 30.

Openings are provided in the top side frame member Il for receiving bolts 'H to attach a handle 12 to the frame member so that the weight of the cleaner when it is lifted oi the floor is transmitted to the skeleton frame structure. A boss 'I4 is formed on the top frame member Il to which a swtch 15 is mounted. Holes 16 are provided in the metal bottom plate for attaching to the latter a pair of cleaner supporting skids 11.
