Description:

This invention relates to a cleaner or duster, which includes two or more dusting members preferably arranged in general parallelism so that they may be used simultaneously to embrace and to dust or sweep two sides of an extended member.

One object is to provide a duster conveniently usable for dusting a plurality of sections or slats of a Venetian blind. Another object is to provide a duster which will dust simultaneously two sides of a molding, a pipe or any other projecting part.

Another object Is to provide in connection with such a duster means for readily adjusting or varying the intervals of the dusting members with respect to each other so that they may be adjusted to dust the slats of a Venetian blind or some analogous device irrespective of the distance between the slats.

Another object is to provide in connection with a duster of the type generally indicated removable dusting fingers. A still further object is to provide rotatable or shiftable dusting fingers so arranged that without complete removal from a handle they may be moved to bring different portions of their surface into contact with the article to be dusted.

Another object is to provide a dusting finger suitable for use in connection with a handle and preferably removable therefrom.

Other objects will appear from time to time in the specification and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:-Figure 1 is a side elevation of one form of the duster; Figures 2 and 3 form together a separate transverse section taken at line 2-3 of Figure 1 on an enlarged scale, showing the handle and a cleaner finger both in section and separated from each other; Figure 4 is a transverse section through the cleaning finger taken at line 4-4 of Figure 3; Figure 5 is an elevation showing the side of the handle and the holes or sockets arranged to receive the engaging parts of the cleaning fingers; Figure 6 is a side elevation with parts in section, showing the core of a cleaning finger;.

Figure 7 is a plan view showing the develop"0 ment of a portion of the cleaning finger covering; Figure 8 is a side elevation illustrating a modifled form of the device to which a handle may be applied; Figure 9 is a side elevation generally similar to Figure 1 but showing a modified form of finger attaching means; Figure 10 is a sectional detail taken on an enlarged scale at line 10-10 of Figure 9; Figure 11 is a view generally similar to Figure 10 showing a further modified form of finger attaching and adjusting means.

Like parts are designated by like characters throughout the specification and drawings.

In the form shown in Figures 1 to 7, inclusive, IM a handle I is used. This handle may have a relatively reduced portion and an extended portion 2 provided with a series of sockets 3. The handle may be narrowed or cut away as at 4 to provide a convenient finger grip and may also have a perforation 5 by means of which it may be hung or through which the thumb or finger of a user may penetrate. It will be noticed that the perforations or sockets 3 are located as shown particularly in Figure 5 at different distances 90 from each other. This is to permit an adjustment of the relative positions of the cleaning fingers, that is to say, to permit the cleaning fingers to be adjusted to provide intervals of work receiving crevices of different size between them so that they may be suited for cleaning blinds or other articles in which the elements to be cleaned are of different sizes or are situated from each other at different distances. Thus fingers may be Inserted in the sockets marked X and six fingers will be used and the intervals between them will be different from those occurring when the fingers are located in other holes. The fingers may be inserted in the holes Y and then only five will be used and the intervals between them will be different from those occurring when the fingers are inserted in the sockets X.

Other holes or sockets are provided to permit the arrangement of fingers in many different ways 4P so, for example, that fingers may be arranged at intervals of 1 inch, 11/4, 11/2, 2 inches and other variations. This will, of course, necessitate the use of dif1ering numbers of fingers in a given handle and in some cases even fingers of different sizes. Fingers can, of course, be spaced so that the intervals throughout are not uniform. Ordinarily this is not the case but it is within the contemplation of the invention that for certain special purposes it might be desirable to have the fingers arranged at any given time with unequal intervals and the arrangement of sockets shown permits that just as it permits the other variations above discussed. This is true of all forms of finger securing means. Some modified forms of these means will be described below and f are illustrated. I As shown in Figure 6 the core or body of a a cleaning finger may consist of a member 6 which 1 is conveniently of wood but may be of any other 1 material and has preferably a rounded end 1.

It may be perforated at 8 to receive a nail 9.

This nail is as shown preferably pointed at each i end and is provided with one or more wings or ]0 feathers 10. The nail is driven into the perforation 8 and is retained therein and held against turning. Obviously a screw might be driven into the wood instead of the nail or the nail might be driven in without a preformed perforation or if made of suitable material an end of the body 6 might be reduced so that it could of itself be inserted directly in the perforation without the need of any such intermediate member as a nail. The nail will be of such size that when inserted in the perforation 3 it is retained by a friction fit but may be removed and may be turned when sufficient force is applied.

While the fingers may be provided with any form of dusting or cleaning material one convenlent form is illustrated which comprises the skin of some animal in which the skin is secured to the body of the finger and hair projects outwardly to furnish the dusting medium.

As shown in Figure 7 a skin II is spread flat.

At one end as at 12 it is straight, at the opposite end it is cut into notched or angular portions 13 which conveniently fold together about the rounded end 7 of the body 6. The fur or hair 14 is retained on the, skin and when the skin itself 33 isn position about the body as shown for example in Figures 1, 3 and 4, it projects outwardly and makes a relatively continuous dusting and cleaning member. As shown in Figure 8 a body 1,, generally similar to the body is shown. It is 4 perforated with one t hreaded perforation 16 and a second threaded perforation I7. A handle 18 is shown as received in the perforation 16 and might be received in the other perforation optionally. The body 15 is provided with perfora4.) tions 3 similar to the perforations 3 shown in Figures 1, 2 and 5 and is also provided with angularly disposed perforations 19. The spaced relationship between the perforations 3 is the same as that described above in detail in conh0 nection with Figure 5 and the spaced relationship between the perforations 19 is also the same. An advantage of having angularly disposed perforation s 19 is that by means of a handle and the position of the perforations the oi cleaner may be used to clean a blind or some other article at a height above the head of the user. Other advantages, of course, will suggest themselves to any user. While the form of Figure 8 shows both the straight perforations 3 and 00 the angularly disposed perforations S9, either might be omitted so that a handle might have merely straight perforations or erely angular perforations or both.

As shown in Figures 9 and 10 the handle I is 63 generally the same as that shown in Figures 1 and 2 but the perforations 3 have been omitted and a different means for securing the fingers is provided. This comprises a member which is conveniently made of a metalstrip 20, bent at its ends as at 21, 21 and secured to the handle by screws 22 or otherwise. The fingers are generally the same as those shown in the earlier figures, comprising a body 6, to which is secured the skin II and which is perforated to receive a TB nail 9 having the wings IS as shown in the earlier orms. The nail 9 is secured to a gripping meni,er 23 which has at one end a flange 24 inwardly Lnd downwardly bent to engage the strip 20; at ts other end it is inwardly bent to provide a lange 25 in which is seated a thumb nut 26. 3y this means the individual fingers may be enraged upon the strip 20 and may be moved along t or removed from it entirely.

As shown in Figure 11 the handle differs somewhat from those shown above. There is a handle portion 27 reduced at 28 to be engaged by the user. The handle is enlarged at 29 and.provided with a dovetail groove 30 which may or may not receive a reinforcing lining 31. The construction of the fingers is the same as that above described but for each finger there is a receiving block 32 shaped to correspond to the shape of the groove 30 and the lining 31 if the latter is present. The block 32 is perforated as at 33 to receive the outer end of the nail 9. A suitable number of thumb nuts 34 is provided so that the individual blocks may be held in adjusted position. By the construction of Figure 11 any desired number of fingers may be inserted into the groove 30 and they may be put in any desired position, being secured by the thumb nuts which may be effective to engage the individual blocks or may be arranged merely to press the lining 31 Inwardly and to engage all of the blocks. It will be realized that whereas I have herewith shown and described a practical operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of the invention and I wish, therefore, that my showing be taken as in a sense diagrammatic.

While the skin is shown as cemented to the core, It might be otherwise fastened. It is convenient to use cement but the core might be slotted and a portion of the skin might be caught or pinched In the slot. A variety of other means for attaching the skin to the core might be In particular the number and shape and dis- 45 position of the dusting fingers may be almost infinitely varied. Any one of the dusters shown may or may not be provided with a handle and one or more handle sockets may be provided, if that is desired. While I have now spoken of the o5 duster as having particular application for cleaning Venetian blinds or moldings or projecting members, it may be used for cleaning a flat surface, and also it may be used with any desired number of fingers. For example, it may be used with only two fingers. While ordinarily it is preferable to shape the handle so that the fingers may be adjusted toward and from each other to vary the interval between them, for some purposes the handle will be so made that the fingers are secured to it and have no such adjustment. If an installation of Venetian blinds is sufficiently large to justify the use of a single duster for them alone, it will ordinarily be unnecessary to provide for adjustment of the fingers toward and from each other.

While I have spoken of the dusting or cleaning fingers as being removable, this language is to be taken as meaning fingers which for practical purposes are removable, even though they might 70 . be secured very tightly to a handle. Conceivably fingers of whatever shape and material might originally be fastened, for example, by gluing to, the base or body portion of the duster, and yet it would be a simple expedient to break the glue TS so as to permit rotation of the finger or removal and replacement, and such a device, even though in a sense the fingers would initially be nonremovable, is within the contemplation of my invention.

I claim: 1. In combination in a duster, a base portion and a plurality of separate, removable dusting fingers, each finger comprising a body portion and brushing parts projecting generally at right angles to the exis of the body portion, and means for positioning said fingers at different intervals with respect to each other whereby to define at different distances from each other work receivSing crevices into which the brushing parts of Ssaid finger project, said means comprising a plurality of sockets, carried by said base, and a socket engaging portion on each of said fingers, whereby the fingers may be removably engaged in the desired socket there being provided a greater number of sockets in said base than there are fingers supported thereby.

2. In combination in a duster, a base portion and a plurality of separate and removable generally aligned dusting fingers, each of said fingers comprising a body portion having laterally disposed cleaning elements, and means for positioning said fingers at different intervals with respect to each other whereby to define at different 3O distances from each other and between the opposed lateral cleaning elements of adjacent fingers work receiving crevices, said means comprising a plurality of sockets carried by said base and a frictional socket engaging portion on each of said fingers, there being a greater number of sockets in the base than there are fingers supported thereby whereby the fingers may be removably engaged In the desired sockets and said fingers may be adjusted individually about 49 their respective axes in said sockets to present new portions of said laterally disposed cleaning elements of adjacent fingers across said crevices when desired.

3. In combination in a duster, a base portion including a handle in combination with a plurality of separate, removable fingers and means for supporting said fingers upon said body at selective, variable intervals with respect to each other, said means comprising pre-formed sup60 ports on said body and frictional support engaging members on said fingers there being a greater number of supports on said body than there are fingers supported thereby.
