This invention relates to an improved dnstr ing tool particularly adapted for removing dust and dirt from Venetian blinds but also useful generally for cleaning the surfaces of other articles and parts.
A primary object of the invention to provide an improved dusting tool of simple, light, durable construction, easy and convenient to handle and by which dust and dirt can be rapidly and thoroughly removed from Venetian blinds.
Anotherobject of the invention is to provide an improved dusting tool of the character referred to adapted to be attached to the suction pipe of a vacuum cleaner whereby dust and other foreign matter on Venetian blinds loosened by the dusting or brushing element of the tool will be removed by the suction, the dust and dirt passing through openings in the brush head to the suction pipe of the vacuum cleaner.
The invention ,cornprehends a dusting tool comprising an elongated, light, tubular body or men-i ber and an elongated dusting or brushing element of general rectangular shape, and another object of the invention is to so form the elongated tubular member that the elongated. .r 1e.a ;l of the brushing unit can be compactly fitted thereon and securely attached thereto by simple means providing for the quick and easy assembly of the parts.
A further object of the invention is .to provide an improved tool of the character mentioned having a brushing unit with a head provided with air openings so shaped and arranged as to provide efiicient suction substantially throughout the full area of the dusting or brushing element.
A still further object of the invention is to provide a dusting tool comprising an elongated tubular continuous body part or member to which a brushing unit is attached, one-end of the tubular body or member constituting a handle tor the tool and which handle portion is offset upwardly from the main portion of the tubular body part or member so that,;in use of the dusting tool,-the hand of the operator grasping the handle or the tool will be spaced from the slats of the Venetian blind and will not rub against the slats in'the brushing operation.
The invention, with other objects, novel features and advantages thereof, and'the particular construction, combination and arrangement .of parts comprising the same, will be understood trom the following detailed description, when considered in connection with the accompanying drawing forming part hereof and illustrating one embodiment of the invention.

While a preierred embod ment of th inve tion is illustrated in the drawing, it Will be 11 d rstood that mi r .ohane s and .m diiisa may be made n the part cular c n t uc ion s own, a d the invention ma be em o ied in th r o m a wi ap ea to thos sk lled the art and falling within the scope of thelappe de la ms w t ou p rt n ii'om ihespiri Of the inv nti Rei r ins t a e l desc t o f th a t u a mb dime t o th in tion i lustrated in the drawing; the construction ,of dusting tool shown includes an elongated tubular nieinber '11 having .at one end a laterally curved portion l 2 terminating in a longitudinal portion 13 forming a h dl o th du t ng t oland which h dle p rtio is adapt d to te escopicall en age the hose ,or suction pipe of a conventional vacuum cleaner, said handle portion 1 3 being offsetlabove the main part of the elongated tubular member and extending substantially parallel .th'erewr The tubular-member .ll is provided in s under.-
sideforwardly-of the ,laterallycur'ved Withalongitudinalrecessllmextending to o1:- ward e ds-a d r ess e g formed by stra h longitudinally extending ,bottom faces '15 .of the forward side wall portions .l..6' and the be, red transversely extending end .iace portions ill! of said tubularmemlqe The tu ula m mber 1 isclp e a it orwa d endib adow wa d an u ward y maime wa l po on 1 Pr je ting 3 forwardly from the bottom portion of the tubular member II at the inner end of the recess [4 is a pointed penetrating attaching portion or prong [9.
The elongated tubular member H is shown as constructed from a length of light metal (preferably aluminum) tubing or pipe of circular cross section and equal diameter throughout, the same at one end being bent upwardly and then outwardly to form the upwardly extending portion l2 and handle portion 13, the reces l4 being provided by cutting away a part of said length of tubing along the forward under side thereof. As shown in Fig. 5 of the drawing, two slits 20 are made in the reduced part of the length of tubing, starting a short distance from the forward end thereof. The partially severed portion between the slits 20 is then flattened and its side edges trimmed to match up with the side edge portions 21 so that, when said intermediate portion is bent down and secured along its side edges 22 by welding or soldering, to the adjacent edge portions 21, it forms the downwardly and outwardly inclined end wall portion l8 closing the forward end of the tubular member. Instead of forming the tubular member H in the manner described, it may be formed by molding the same from any suitable metal or plastic.
The tool has a dusting unit comprising a head or base 23 and a dusting element 24 secured thereon, the dusting element being shown as consisting of bristles. The head or base 23, which is of elongated general rectangular form, fits into the longitudinal recess M in the tubular member H as shown in Fig. 1, one end of said head or base fitting against the curved transversely extending end face portion ll of the tubular member, and the head or base at its upper side fitting against the straight longitudinally extending bottom faces l5 of the forward reduced side wall portions 5. The head or base 23 is provided in its top face with longitudinal grooves 25 to receive the lower marginal portions of the side wall portions l6 and a suitable cement 25a is placed in said grooves to provide an air-tight seal between the parts.
The head or base 23 is provided at its forward end with a short beveled face 26 against which the lower end of the inclined end wall (8 of the tubular member ll fits, the construction being such that a complete air-tight seal is provided between the upper part of the head or base 23 and the marginal portions of the tubular member l l, the reduced forward portion of said tubular member forming a suction chamber 21 at the upper side of the head or base 23.
r The head or base 23 at its rear end is secured to the tubular member II by the pointed prong or spur 19 which enters the inner end of the head or base when the latter is forced longitudinally into position into the recess 14. After the head or base 23 has been seated in the recess l t, with its inner end in engagement with the attaching prong or spur l9, it is tightly clamped to the tubular member II by a screw 28 extending transversely through an aperture 29 in the tubular member H and entering into the head or base 23. As will be understood, this particular fastening means is simple and efficient and provides for the quick and easy assembly of the parts. The head or base 23 is provided with a plurality of elongated air and dust openings or slots 30. through the head or base 23 from top to bottom thereof, the sameproviding passages leading These openings or slots 30 extend.
from the under side of the head or base through the same to the suction chamber 21 at the upper side of the head or base. The elongated openings or slots 30 are arranged to extend parallel with each other transversely of the head or base at an inclination to the longitudinal axis of the same. This particular arrangement is especially advantageous in providing for efficient suction throughout the full area of the bottom of the head or base 23 and the bristles 24, and for the picking up of dust and dirt loosened by the bristles 24 as the tool is moved in contact with a surface in a path transversely of its longitudinal axis.
The invention broadly comprehends the use of any suitable dusting material on the head or base 23 in place of bristles. When a cloth or fabric is employed as the dusting element, it will be provided with uitable openings extending through the same and registering with the elongated openings or slots 30 in the head or base 23.
In Fig. 8 of the drawing, is shown an adapter coupling member 3| to provide for telescopically connecting the tubular handle portion 13 of the tool with the suction pipe or hose designated 32 of a vacuum cleaner when the diameter of the vacuum cleaner suction pipe is such that the tubular handle l3 of the dusting tool will not snugly fit directly into or over the same as desired, said adapter coupling 3 I as shown, being of tapering formation.
It will be understood that my improved dusting tool is adapted to be employed as a brush for cleaning Venetian blinds or other articles or parts without being connected with the suction pipe of a vacuum cleaner, as well as for use as an attachment for vacuum cleaners.
In the use of the brushing or dusting tool as a simple brush without being connected to the suction pipe of a vacuum cleaner, the Venetian blind to be cleaned is first raised to approximately twenty (20) inches to the top of the window by the pull cord and the slats closed through the tilt cord. Then, take the brush and, with a crosswise motion, go over the entire slats. Next. reverse the slats by the tilt cord and go over that side of the blind. Then reach behind or underneath the Venetian blind with the brush or dusting tool and repeat the cross-wise brushing motion. After the top slats are cleaned, lower the blind about twenty (20) inches more and continue the brushing operation as before until the entire blind slats and tapes have been thoroughly cleaned or dusted.
When the dusting tool is u ed as an attachment for Vacuum cleaners, the tubular handle being connected with the suction pipe of the conventional vacuum cleaner, the same procedure is followed as before in cleaning Venetian blinds but. in this case, the dust and dirt on the Venetian blind, as it is freed therefrom by the brushing element, will be picked up by the suction from the vacuum cleaner, the dust and dirt being drawn upwardly through the slots or openings 30 in the head or base 23 of the brushing unit into the suction chamber 21 and passing outwardly through the tubular handle portion [3 to the vacuum cleaner pipe 32.
It will be noted that the invention provides an efiicient dusting tool of simple, light, durable construction. The elongated brushing unit with its head fitting into a recess in the under side of the elongated continuous tubular body member.
. results in a compact satisfactory construction,
and the special means for attaching the head of the brushing unit to the elongated body member affords a simple, eificient attaching means that provides for the quick and easy assembly of the parts.
The improved dusting tool is easy and convenient to handle, the upwardly offset tubular handle portion formed continuously with the tubular body part or member providing for operating the dusting tool without the hand of the operator, rubbing against the surface being cleaned, and the beveled forward end of the tubular body member making it easy to insert the tool into the space at the front of the Venetian blind without the same catching into adjacent drapes. As will be appreciated, the particular arrangement of the elongated openings or slots in the head of the dusting unit extending at an inclination to the longitudinal axis of the same provides for especially effective cleaning action as the brush is moved sidewise longitudinally along the slats of a Venetian blind.
