Abstract
Abstract The hand-held tool head assembly comprises a housing connected to a flexible vacuum hose to a source. The housing has an elongated front wall with a plurality of openings defining a suction surface. An intermediate portion of this wall is cut-out and formed with a receiving structure for receiving inserts. A first insert has a front wall portion with openings so that when it is received in the cut-out portion it is flush with the surface openings on either side of the cut-out to provide a continuous elongated cleaning surface. A second insert is arranged to be substituted for the first insert and has a front undulating suction surface defined by transverse fins with channels therebetween, the side walls of the fins, the front tips of the fins and the floors of the channels all having openings communicating with the interior of the tool head to provide suction surfaces for drapery pleats received within the channels. By use of the second insert, the tool head can rapidly be converted to provide a cleaning device for drapery pleats.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
354 words
A drapery and drapery pleat cleaning tool head assembly for connection to a vacuum hose extending from a cleaning machine, said tool head assembly including, in combination: (a) a housing comprised of wide front ended top and bottom walls spaced relatively close together with left and right side walls converging towards each other in a rearward direction to merge with narrowed rear end portions of said top and bottom walls into a cylindrical portion having a rear end opening for connection to said vacuum hose, and an elongated front wall extending between the front ends of the top, bottom, left and right side walls, said front wall having a plurality of openings communicating with the interior of the housing to provide a front suction surface for engaging drapery material, a portion of said elongated front wall and corresponding extending portions of said top and bottom walls intermediate the front ends of said side walls defining a cut-out; and (b) insert receiving means secured in said cut-out for mounting in operative position different inserts whereby a first insert can be received in said insert receiving means, with a front wall portion flush with said elongated front wall on either side of said cut-out and with openings positioned to provide continuity with the openings in said front wall to define a continuous suction surface between the front ends of the left and right side walls for efficient cleaning of depending drapery material; or whereby a second insert can be received in said insert receiving means with an undulating front wall portion defining transverse fins with channels therebetween, the side walls and front tips of the fins, and floors of the channels having openings connecting with the interior of the housing, so that pleated portions of drapes may be received in said channels between the fins and end channel walls to enable the pleat surfaces and inner folds of the pleats to be subject to suction and thereby cleaned while portions of the drapes on either side of the pleated material are cleaned by the portions of the elongated front wall on either side of said cut-out.
Claim 2
Dependent Claim
354 words
A drapery and drapery pleat cleaning tool head assembly for connection to a vacuum hose extending from a cleaning machine, said tool head assembly including, in combination: (a) a housing comprised of wide front ended top and bottom walls spaced relatively close together with left and right side walls converging towards each other in a rearward direction to merge with narrowed rear end portions of said top and bottom walls into a cylindrical portion having a rear end opening for connection to said vacuum hose, and an elongated front wall extending between the front ends of the top, bottom, left and right side walls, said front wall having a plurality of openings communicating with the interior of the housing to provide a front suction surface for engaging drapery material, a portion of said elongated front wall and corresponding extending portions of said top and bottom walls intermediate the front ends of said side walls defining a cut-out; and (b) insert receiving means secured in said cut-out for mounting in operative position different inserts whereby a first insert can be received in said insert receiving means, with a front wall portion flush with said elongated front wall on either side of said cut-out and with openings positioned to provide continuity with the openings in said front wall to define a continuous suction surface between the front ends of the left and right side walls for efficient cleaning of depending drapery material; or whereby a second insert can be received in said insert receiving means with an undulating front wall portion defining transverse fins with channels therebetween, the side walls and front tips of the fins, and floors of the channels having openings connecting with the interior of the housing, so that pleated portions of drapes may be received in said channels between the fins and end channel walls to enable the pleat surfaces and inner folds of the pleats to be subject to suction and thereby cleaned while portions of the drapes on either side of the pleated material are cleaned by the portions of the elongated front wall on either side of said cut-out.
Claim 3
Dependent Claim
43 words
A tool head assembly according to claim 1, in which said insert receiving means includes opposed spaced surfaces having inwardly projecting keys with spring biased ball means therein whereby inserts with cooperating key ways and detent means can be removed and replaced manually.
Claim 4
Dependent Claim
51 words
A tool head assembly according to claim 1, in which the elongated extent of said insert receiving means is between one fifth and one half the overall distance between the front ends of the left and right side walls of said housing defining the opposite ends of said elongated suction surface.
Claim 5
Dependent Claim
96 words
A tool head assembly according to claim 1 in which said plurality of openings comprises two adjacent off-set parallel rows of openings, the dimensions of the openings as measured in the direction of elongation of said suction surface being greater than the spacing between successive openings so that the openings in one row overlap the openings in the adjacent parallel row to assure that all the surface area of a drapery is clean when the tool head suction surface is moved in a direction at right angles to the direction of elongation of said suction surface.
Claim 6
Dependent Claim
