npplication December 19, 1947, Serial No. 792,703

The present invention relates to improvements in brushes and, more specifically, to a brush for paintersenamelers, varnishers and the like, with which inl-Hann economic and simple manner a completepainting job can be done with the use of a single brush. :For painting, enameling, or varnishing a house or furniture, a painter needs an expensive set of brushes, which if not in-use con-4 stantly deteriorates,- so that its useful period of lifeis reduced. Y

M Itv practically impossible for apainter to clean thoroughly a brush whichA is going to be used fora few'hours later during the same day.

For the painting of walls and ceilings usually a brush of 6" in width is used; for the woodwork a brush or 4" is used; for trimming a brush 3" or 2;-then for painting small parts and for retouching a l brush is needed. From this set of brushes only thebrush 1" can be cleaned and usedw the 4same day, because it'v iseasy to remove the solvent used for removing the oil Vand pigment from this small brush. From a bigger brush it is impossible to remove the solvent, mostly it is vleft to evaporate overnight. A brush soggy with solvent spreads a thin film of paint which tends to run, and also the solvent keeps dripping for a long time, injuring other surfaces which were vpainted or are going to be painted. A painting` job done with a brush which contains solvent, in a few months shows that the painter had no'skill in his art, because the paint peels or cracks. If the brush is put aside without cleaning, in one or two hours the bristles become stiff and fragile and break at the points where the pressure requiring flexibility is exerted.

Another reasonA for the destruction of a brush is the accumulation of pigment at the base of the bristles, which is removed only in part at the cost of a few hours labor and by the application of strong-solvents which slowly kill the flexibility of the bristles.

Moreover, the rapid destruction of a brush also resultsv from the fact that the frontal and lateral bristles are subjected to almost all the friction and wear out more quickly than those at the center rows.

Therefore, one object of the present invention is the4 :provision of a sectional brush consisting of narrow sections more or fewer of which can be attached to one another for the purpose of enlarging or reducing the width of the brush; sections which are not in use temporarily can be kept in a solvent in order to avoid the bristles becoming stiff and the pigment set at the base of them. Said sections are of a small size, so that i claim. (o1. -202) with the help of a paper or rag 'all solvent easily can be removedthus avoiding dripping and dilution ol the material used forfpainting.

Another object of the presentinvention is the provision of a sectional brush whose sections canbe interchanged easily with one another and without the application of any considerable VV amount of skill, so that a constant excessive wear of one and the sa.; e bristles at the end portions of the brush will be avoided.

Still another object of the present invention is the provision of a sectional brush which, although it is only one unit, will substitute an entire-set of separate crushes of different length and width, thus greatly reducing the expenses for paintingand varnishing equipment.

With the foregoingand other objects in View which will appear as the description proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinaftermore fully described and pointed out in the claim, it being understood that changes may vbe made in the construction and arrangement of parts Without departing from the spirit of the inventionas claimed.

ln the accompanying drawing the preferred forms of the invention have been shown.

in said drawing:

Figure 1 is a front elevation of a preferred ein-1 bodiment of my invention;

Fig. 2 is a side elevation of the same;

Fig. 3 is a front elevation of a modification; and

Fig. 4 is a side elevation of the modiiication of Fie'. 3.

The numeral l denotes a center brush head.

section having flat, parallel sides and being provided with bores which are extended there.

through at right angles to said flat sides. A hanvdle portion 1 extends from the upper extremity of the section l and preferably is made as a unit therewith as in the instance shown, and bristles 8 are attached to lthe lower portion of the section sides of the section l are a plurality of lateral brush sections. In the present instance there are bolts Il) and nuts Il. g through bores in the lateral sections 2 to 6 and ten sections 2, 2', 3, 3', 4, d', 5, 5', 6 and 6'. These lateral sections, which also are provide-d with bristles B, are' detachably connected to one Y another and to the center section l by any suitable means, for instance by means of a pair of The bolts I0 are extended 3 2 to 6' inclusive. Said bores register with the bores in the center section I. ,f

With this arrangement it is -easy to interchange the various lateral sections with one another. For instance, the sections 6 and 6 can be interchanged with the sections 2 and 2', and the sec- `tions and 5' can be interchanged with the sections 3 and 3', so that the bristles of the outer sections are not subjected constantly to excessive wear.

Also the width of the brush can be changed easily by attaching more or fewer lateral sections to the center section. Bolts of ldifferent length preferably are used in connection with variations of the number of lateral sections attached to the center section I. y

Since the bristles 8 are made of a uniform length, which is just the right length for the largest possible brush width attainable with this device. it is desirable to reduce the effective length of the bristles in correspondence with a reduction of the width of the brush. I prefer to carry out this feature of my invention in the manner shown in Figs. 3 and 4 ,1 Where it will be seen that a clamp I2 is used for this purpose. In Fig. 3 only four lateral sectionsv 2, 2', 3 and 3 are attached to the center section I by means of short bolts and nuts II. The clamp I2 consists of any suitable resilient material, such as sheet steel, plastic material, or/the like. It has a perforation I5 in its back lIII for extending therethrough the handle 1. A pair cf blade portions vI6 and I'I arel adapted tol press with their lower extremities laterally in opposite direction against the bristles 8, thus reducing the effective length of the bristles 8 to that portion of them which protrdes beyond the lower extremities of the "bladeportions .I6 and I'I, as shown in Fig. 4.' Lateral overlapping tongue sections I8 and I9 may be extended rectangularly from the blade portions I6 and I'I, in order to prevent a sidewise dislocation of the bristles 8. For each width of the brush, or for each pair of lateral sections, and for the center section I, preferably one clamp I2 is furnished with the device.

SinceI certain changes maybe `made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limited sense.

It is also to be understood that the following claim is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent in the United States is:

A sectional brush comprising a brush head center section provided with a handle and bristles and having at side portions from which a pair of reinforced bores are extended through the brush head center section, a plurality of lateral brush sections each of which consists of a narrow brushhead with bristles thereon and having flat side portions and being Vprovided with a pair of reinforced bores which register with the bores insaid' center section, a bolt provided with anut being extended through each row of registering boresin said sections for detachably connecting said lateral sectionsv to one another and to said center section, and a U-shaped clamp consisting of a perforated back portion and a pair of resilient blade portions extending downwardly from said back portion and being slipped over the brush, thereby the handle 'being extended through the perforation in the back portion of the clamp while the lower sections of said blade portions press upon the bristles in opposite lateral direction.
