Definitions

  • the present invention relates to suction cleaners and more particularly to a new and improved filter adapter therefor.
  • Filter adapters heretofore proposed are ob- J'ectionable for various reasons chief among which are their mechanical complexity, high cost, difficulty to operate, tendency to rupture paper filters opposite the clamping means, and inadequate clearance between the seating tube and clamp. for convenient replacement of the filter.
  • the present invention overcomes all of the above mentioned shortcomings of prior adapters and provides a very simple, inexpensive and highly effective. construction.
  • the unique clamping means; forming an important feature oft e. invention acts to gather the filter neck tightly about, the. seating tube in an air-tight manner and to lock. it. in place pos iv ly.
  • Th clamp is .0 designed as to. open easily, and in so doin ,v to move to a position entirely removed irony. the seating tube so as not tov interfere in any manner with, the removal or replacement of. the filter.
  • a filter adapter for a suction eaner o the like which is; characterized by uniqueness, simplicity, low cost, ease of p,e1a,-. 1 ef tiv e s, nd convenience.
  • Another object is the provision of; av novel a a t r a d fi r cl mp h ch. c t-hers the filter inlet about a tubular support so, as. to, form a fr c i n l g ip and seal between. he fi t r nle and the suppcr nc tu e- A, fi r her b e t,- is t e r vis on, of an. adapter a d fi t r amp hi h oe n t cause the filter o rup e pp i e cl p n means.
  • Figur 1 is a side of a suction cleaner with. the filter adapter shown in enlarged scale. and in vertical section; and
  • Figure 2 is a top plan View on line 2 --.2 of. Figure 1.
  • FIG. 1 An illustrative embodiment of; the invention is shownas. comprising a suction cleaner ⁇ 0; of; any well known type.
  • the cleaner body is supported on wheels l3 and a propelling handle l4 is pivotally connected to the cleaner body inany desired manner.
  • the exhaustair passageway I5, is: cast integrally with the cleaner body 1G and opens. upwa dly and rearwardly, as indi cated in Figure 1.
  • the filter adapter assembly includes a bag ring Hi which can be removably secured to exhaust conduit l5 in any preferred manner.
  • the inlet end of a flexible rubber bellows H is secured to the inner periphery of ring [6 as by a split ring keeper l8.
  • the inlet end of the bellows serves as a sealin gasket between ring it and exhaust conduit 15.
  • a tubular filter seating adapter I9 is attached to the upper end of bellows H by a sheet metal sleeve 20' which is locked in place on inwardly extending flange 21 by beading 22.
  • spring 25 acts. normally to. hold the adapter and the filter closely adjacent the underside of propelling handlev M. If the handle is lowered; the adapter and. filter pivot downwardly about; hinge 24. If, on the; other hand, the, handlev is raised, spring 25 urges; the adapter and filter to. follow it u r ward'ly.
  • a apter tube l9 may e circular or or any other cross-sectional shape and its discharge. end may be of; smaller diameter than its lower inlet e d t iacilitate placement of. a filter thereover,
  • One or more longitudinally extending areas of its: surfac are depressed. as indicated at 26., As here shown-there is only one longitudinal de pr ssicn 26 extending upwardly from the; base, r member is and terminating somewhat short oi the upper end of the adapter. In pra ti it has: been fou dthat onesuch depression is adequote and, th s i particularly true when using a. lterbag having. an, inlet. neck of reduced diameter as; is common practice.v However,.
  • the adapter is designed for use-with a. filter having a lar e inlet ne k, it may be desirable. tohave a. plurality of depressions at spaced. points around the adapter.
  • the purpose of the dc.- Dresslons is to receive gathered portions of the filter neck, in such manner that the filter firmly grips adapter tube IS. The manner in which this is accomplished will become more apparent below.
  • the clamping device for gathering neck 21 of a paper filter 28 comprises a plate 29 pivotally connected to the upper end of arm 23 by a hinge 30.
  • of the shape shown in Figures 1 and 2 are secured to the underside of plate 29 as by the lateral inturned edges thereof.
  • One end of a leaf spring keeper 32 is secured to the base of tubular member l9, while its free end is positioned to latch over the edge of opening 33 in plate 29. When so latched, spring 32 looks the filter clamp in the position shown in Figure 1. In this position, resilient fingers 3
  • Operation ator'then takes a new paper filter bag 28 and telescopes its inlet end 27 downwardly over adapter tube I9.
  • the filter neck is of suihcient diameter 'to slide easily over the adapter tube and, preferably, its end is cut off at an angle tothe filter center-line as an aid in guiding it onto the adapter.
  • a notch 38 interfits with a locator abutment 39 located on the lower side of the adapter tube and assures that the longer side of the filter neck will overlie depression 26 in the adapter tube. After the filter is in place, the operator simply pivots the clamping device downwardly until it is latched by leaf' spring 32.
  • the present device provides an adapter and a filter clamp therefor which is extremely simple in construction and in operation.
  • the size of the filter neck may vary over a considerable range in view of the large gathering capacity of resilient fingers 3 I. These fingers act to gather all excess material of the filter and to draw it tightly about the" tube. Thereafter the resiliency of fingers 3
