STATES PATENT OFFICE.
SVEN' MALCOLM BLANCH, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO FLEMING MACHINE COMPANY, OF WORCESTER, MASSACHUSETTS, A' CORPOELA'RION OF MASSACHUSETTS.
WIRE BRUSH.
Application filed September 28, 1923. Serial Nb. 665,451.
To all whom it may concern:
Be it known that I, Svnn MALCOIM BLANCH, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Wire Brush, of which the following is a specification.
This invention relates to a wire brush of the circular type adapted to be rotated on the axis of the circle and having the ends of the bristles arranged in" a circular plane for the purpose of removing substances from plane surfaces. It is particularly applicable for. removing carbon deposits from internal combustion engines, but is also capable of general application.
The principal objects of the invention are to provide a detachable construction of brush element which can be taken out and discarded when worn and replaced by a new element without necessitating the loss of the entire device; to provide a convenient means of holding the bristles in a head and clamp-- ing them thereon to still more securely hold them and to provide for locating the bristles on the head in such a position that there will be spaces between the groups of bristles which I find renders the device more eflicient for the particular purposes described above.
Reference is' to be had to the accompanying drawings in which Fig. 1 is a side view of a complete wire brush constructed in accordance with this invention and showing one way in which it can be used;-
Fig. 2 is a central longitudinal sectional view of the same;
Fig. 3 is a side view of the brush element removed from the rest of the device;
Fig. 4: is a plan of the same; and
Fig. 5 is a bottom plan or end view of the bristles.
In Fig. 1 I have shown the brush as mounted on a flexible shaft 10 which enters the head of the brush axially so that the brush rotates on its longitudinal axis and I have shown the brush as working against a plane surface as is done for the removal of carbon.
The brush preferably is made of a plurality of elements. One of these consists of the brush element itself and comprises a plate 12 shown as circular in form and having a central perforation 13. This also has a circular row of smaller perforations 14 around it near its edge. In each of these perforations 14 are inserted and driven in a group of wire bristles 15 so that they are retained in place by friction. I find it convenient to employ five in each group. These perforations of course are separated from each other and this provides a separation between the groups of bristles which extends clear to their operative ends. In this way the end of the brush that is designed to operate on the work has the equivalent of teeth. The spaces between the ends of the groups of bristles separate these groups in such a way that they act in that manner and there is no necessity of filing off the bristles at any point to form teeth to secure an efficient grinding action.
The ends of the bristles are allowed to project up above the plate 12 and are bent over inwardly in a radial direction. This is suificient to hold them in place and I find that this element is all that is really necessa to form the brush except to provide a astening means to secure it to a shaft. However, or the purpose of more securely holding it, I place a cup-shaped cap 20 over the top of the brush and pass the end of the flexible or other shaft 10 through this and the plate 12 of the brush element and fasten the three together against a shoulder 19 on the shaft by' means of a nut 21.
This constitutes a very superior brush for cleaning carbon from gas engines, the reasons for which have been stated above. The bristles are firmly secured in position in the brush element itself and with the cap on any tendency which they might have to become loosened is resisted at the outset. The separate brush elements can be kept in stock and sold separately to users to permit them to replace worn elements in their brushes at will.
I am aware of the fact that annular wire brushes have been designed and put on the market heretofore but so far as I am aware they have involved a continuous row of bristles. The result is that although the ends of the bristles would naturally be expected to dig into the 'work, they are so close together that such a brush has substantially the effect of a continuous surface.
' In other words, it has'no teeth. This brush is an im rovement over that because the groups 0 bristles are separated from each other-by spaces and therefore as they rotate they come up against the work in the same way as they would if the old form of brush were filed ofi at the ends of the bristles to form an irre lar or toothed surface.
Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim.
Therefore I do not wish to be limited to all the details of construction herein shown and described but what I do claim is In a brush, the combination of a circular plate havin a circular row of perforations therethroug near its circumference, a grou of wire bristles projecting through eac perforation to provide a single annular'row of groups with a hollow space within, and each headed over radially and inwardly on the back of the plate so as to extend toward the center, and a cap on the brush secured thereto against the projecting ends of the bristles to secure them in place.
In testimony whereof I have hereunto afiixed my signature.
SVEN MALCOLM BLANCH.
