A further object of the invention is to provide, in a manner as hereinafter set forth, a tool of the class referred to including a combined caris 'rying and retaining means common to a pair of oppositely inclined cleaning elements.

A further object of the invention is to provide, in a manner as hereinafter set forth, a tool of the class referred to including a holder for cleaning elements and with the holder having means to provide for the interchanging of the cleaning elements.

A further object of the invention is to provide, in a manner as hereinafter set forth, a tool of the class referred to including a cleaning element of the brush type having means to prevent the scattering of dust and also to keep dust, threads and other particles from getting caught in the bristles of the brush.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a cleaning tool which is simple in its construction, strong, durable, compact, thoroughly efficient in its use, adjustable, readily assembled and comparatively inexpensive to manufacture.

With the foregoing and other objects which may hereinafter appear, this invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and as are illustrated in the accompanying drawings wherein is shown embodiments of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figures 1, 2, and 3 are respectively an end view, a cross sectional view and a front elevation of the tool,

Figure 4 is a perspective view of the form of end retainer employed for the cleaning elements,

Figure 51s a cross sectional view of a modified form.

Figure 6 is a cross sectional view of still another modified form,

Figure 7 is a side elevation, broken away, of the form shown in Figure 6, and

Figures 8 and 9 are perspective views of the cleaning elements of the form shown in Figure 6.

The tool, with reference to Figures 1 to 5. includes an elongated carrier or holder 8, a handle I, a pair of oppositely disposed end retainers I. 9 of like form and a pair of oppositely inclined cleaning elements extended from the forward or leading corners of the carrier 8.

In Figures 1, 2, and 3 the cleaning elements are designated IO, N and in Figure 5 are indicated at l2, It. The difference between the form shown in Figures 1, 2, and 3 with respect to that shown in Figure 5 resides solely in the construction of one of the cleaning elements. Otherwise than that as stated the form shown in Figure 5 will be the same as that illustrated by Figures l, 2, and 3.

The carrier or holder i is in the form of an elongated substantially solid block it ofsubstantially rectangular parallelepiped contour. The block may be formed of any suitable material and preferably wood will be employed. The block it includes a rear flat upstanding rectangular fol- 35 lower face or side Ii, a horizontally disposed lower flat rectangular follower face or side it, a horizontally disposed upper flat rectangular follower face or side I1 and an upstanding flat rectangular leading face or side it. The ends of the block are of substantially square contour. when the tool is used, the block is disposed in a manner whereby the faces II and II will extend at a forward inclination from bottom to top and the faces 18, ll forwardly at a downward inclination from the face It. The leading-face it is of less length than that of the faces l5, l6, and H. The side faces I6, I! are of different lengths and of less length than that of the faces I! and II. The faces It, I! merge at their follower ends into the ends of face IS. The leading ends I9, 20 of faces l8, l1 respectively are spaced outwardly adjacent to the ends 2|, 22 of the face I I. The ends II, 22 are arranged inwardly with respect to the ends of face It. The width of faces l5, l8, l1, and I8 correspond. The block I4 is formed centrally with a threaded socket 23 opening at the rear face I! for the reception of the threaded end terminal portion 24 of the handle ,7 whereby the latter and carrier i are secured together. The socket I3 is intersected by the transverse and longitudinal medians of the block ll.

The block I4 is formed with a pair of oppositely disposed diagonally extending grooves 25,

- choring the ear '43 to carrier 6.

26 opening at their ends at the leading corners of block M. The groove is of greater depth and width than groove 26. The

side walls

21, 28 of groove 25 merge into the leading end l9 of face |6 and into the lower end 2| of the face l8 respectively. The side walls 29, of groove 26 merge into the leading end 20 of face l1 and into the upper end 22 of the face"|8 respectively.

With reference to Figures 1, 2, and 3, the carrier 6 is. shown as having extending into the grooves'25, 26 thereof cleaning elements IO, M respectively. The element I6 is of the brush type and includes a head 3| corresponding in length to that of groove 25. The head 3| is provided preferably with a pair of spaced parallel channels 32, 33 opening at the sides thereof. Anchored in and extending from the grooves 32, 33 are the

rows

34, 35 respectively of tufts of bristles arranged in a manner to form a flared brush- ,ing means. The head 3| is secured, by any suitable cementitiousmaterial, in groove 25, completely fills the latter,"is flush with the end |9 of face I6 and extendsbeyond the end 2| of face I 8. The element II is of the squeegee type am is formed of a series of flared laminations 36 of rubber. The element H is secured, by any suitable cementitious material, in and completely fills the groove 26, as well as extends outwardly from thelatter. The elements IO, N are dis posed at opposite inclinations with respect to each other and diagonally relative to carrier 6.

The

retainers

8, 9 are. of like construction and each is connected to an end and the leading face of the carrier. The

retainers

8, 9 act to protect the ends of and prevent the cleaning elements, which are mounted in and extended from the carrier or holder 6. from shifting lengthwise of the latter. Each retainer includes a plate 31 having oppositely curved inclined forward or leading

corners

38, 39 and a forward or leading end 40 of less length than its rear or follower end 4|. The corner 38 is of greater length than corner 39 and has its ends aligning with the end |9 of face l6 and the end 2| of face |9 of carrier 6. The ends of corner 39 align with the end 20 of face H and the end 22 of face l8 of carrier 6. The sides 42 of plate 31 are flush with the faces Hi and ll of carrier 6. The end 4| of plate 31 is flush with the face |5 of carrier 6. The plate 31, at its forward or leading end, is formed with a tapered inwardly extending aperturedear 43 positioned against the face |8 of carrier 6. The aperture in ear 43 is indicated at 44 and through which extends a holdfast means 45 for detachably an- The ear 43 is disposed at right angles to the forward or leading end of plate 31. The latter, in proximity to its rear or follower corners 46, is formed with openings 41 for the passage of holdfast means 48 fordetachably anchoring the plate 31 to an end of the carrier 6.

With reference to the modified form in Figure 5 the cleaning element I2 is of the same form as element In. The cleaning element I3 is a polisher and of the squeegee type. The element |3 consists of a strip of felt 48 which is to be of the same contour as that of element The element l3 includes a contracted inner portion 49 completely filling groove 26 and a non-contracted outer portion '50. Otherwise than that as stated the form of tool shown in Figure 5 would be the same as that shown in Figures 1 to 4.

The

inclined corners

38, 39 of the plates 31 prevent the extending ofl'the plates to overlap the bristles at the ends of the rows outwardly adjacent to head 3|, as well as preventing the extending of the plates 31 to overlap the ends of elements l3 outwardly adjacent the carrier 8 whereby lateral end movement of the brushes and elements |3 will not be retarded when the tool is active.

With reference to Figures 6 to 9, the tool 48 includes a carrier or holder 49 and a handle 59. The carrier 49 is of the same form as the carrier 6, with the exception that it is formed with two pairs of spaced threaded openings extending inwardly from its leading face 5| to the

grooves

52, 53 which receive the cleaning elements. The openings of one pair are designated 54 and communicate with the groove 52. The openings of the other pair are indicated at 55 and communicate with groove 53. The openings 54 align with the openings 55. The

grooves

52, 53 are of like width and depth and are arranged in the carrier 49 in the same manner as the grooves I9, 20 are arranged in the carrier 6. Otherwise than that as stated the carrier 49 and handle will correspond to that of carrier 6 and handle 1. In the tool shown in Figures 6 to 9

retainers

56, 51, corresponding in form and arrangement to the

retainers

6, 9, are employed.

The tool 48 includes a cleaning element 58 of the brush type formed of a head 59, a body of bristles 66 and a resilient apron 6| encompassing the body of bristles. The apron 6|, at its inner end 62, is anchored to the outer face of head 59 and has its outer edge 63 positioned in proximity to the outer end 64 of the bristles 60. The apron 6| is preferably formed from a. sheet of rubber. The head 59, at one side, is formed with a pair of spaced aligning cavities 65. The head 59 is arranged in the groove 52 in the same manner as the head 3| is arranged in groove i9. When head 59 is positioned in groove 52, the cavities 65 align with the openings 54. The element 58 is detachably secured in groove 52 by a pair of binding screws 66 which extend through the openings 54 and bind against the walls of the cavities 65. The apron 6| acts to prevent the scattering of the dust or dirt and further acts to keep dust or dirt, threads and other particles from getting caught in the bristles.

The tool 48 also includes a cleaning element 61 functioning as a polisher and is of the squeegee type and includes a head 68 and a strip of felt 69 formed of a contracted inner portion 16 and a non-contracted outer portion 1|. The portion 1| is arranged within and secured to head 68. The latter has one side formed with a pair of spaced aligning cavities 12. The head; 68 is positioned in groove 53, and when so positioned j the cavities 12 align with the openings 55. The

element 61 is detachably secured in groove 53 by a pair of binding screws 13 extending through openings and bind against the walls of cavities 12.

The heads 59, 681 of elements 58, 61 respectively are of the same size whereby provision is had for the interchanging or selective positioning of the elements 58, 61 relative to the

grooves

52, 53.

The bristles may be anchored to head 59 in any suitable manner, but preferably head 59 will be formed with a pair of parallel channels 14. The tufts of bristles are anchored in the channels whereby they are arranged in parallel rows. The head 68 is formed with a groove 15 to receive and contract a part of the strip of felt 69.
