stationary, the. burnisher being shown as mountedon a flexible shaft connected to an Be it known that l, Gnonon owns, a subject of the King of Great Britain and lreland, residing at 100 Evering road, Stoke llewington, in the county o't London, England, have invented certain new and use ullrnprovements in Burnishing anc Scaritying Devices, and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the, same,reierence being had to the accompanying draw'n'gs, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to burnishing and scarifying apparatus, the object of the inburnisher in the distended condition as-.

the combustion chamber of an internal coinnisliedpor scarilied by a burnisher of the form shown in Figs. 1 and 2. Figs. 4: and 5 are respectively, a front elevation and a side sectional elevation of a second form of barnisher in th'e distended condition.

In carrying out the invention according to one form the burnisher a, Fig. 1, comprises a plurality of steel links or chain mail so as to form a circular disk, when rotated, as indicated in Fig. 2. The disk is'niounted at or near its geometrical center on a socket I), screwed or otherwise secured to :the end of a flexible shaft 0, which may be incased as scaritier which can be readily passed through comparatively small and awkwardly shaped apertures or passages into interiors of various shapes and dimensions, and then expanded and rotated within said interiors so as to burnish or scaiity the Walls oi said interiors or other parts therein, theburnisher or scariiier automatically adapting itself to irregularities or variations in the shape tor f. q

So long as the shaft 0, is still or only slowly rotating, the bnrnisher or scarifier a, remains in a collapsed and compact form as the operator.

The invention is particularly applicable to the buruishing or scaritying ot' the comhustiou chambers, piston-heads and jj like parts oi? internal combustion engin to remove carbon and other depos' y from without the necessity for ,(lismoiinting the cylinders. y i Q The apparatus, according to the inven* tion, comprises a burnisher or'scai'iiier, con sisting ot a plurality of steel or like elements loosely linked together and mounte on the end of a flexible shaft or extension thereof, which may be rotated at a suitable speed by any suitable means, such as an electric or other motor. i The elements are preferably in the form ot'stcel links, wires or chain mail and are also preferably intermesh'ed and symmetrically arranged in the term of a flexible disk of circular, square or other outline mounted at or near its geometrical center on the. shaft. Some of the elements, for instance,- on the outer edge of the disk, may. be provided with serrations or cutting teeth.

The accompanying drawings illustrate easily inserted through any convenient orilice, such as a valve port 7, Fig. 3, or spark plug hole, into the combustion chamber lb, of the cylinder 1', which is to be operated upon, the piston In, of such cylinder being brought into its innermost position as indicatedin tions of the cylinder being exposed to the action of the burnisher or scarifier. When the burnisher or scaritier a, is rotated it expands, under centrifugal force, and adapts itself to the irregular shape of the interior surfaces to; which it is applied, and while rotating it may be moved in any require direction by the operator, by means 0 th flexible shaft 0, or casing d, thereof, thus scaritying and loosening the deposits wit which the burnisher or scarifier a, is brought into contact.

cated in Figs. 4 and .5, some of the elements of the burnisher or scarifier may comprise links a, as inthe form previously described,

but others, r'or instance. at the outer edges of the disk, may be in the form of plates Z, having serrations or cutting teeth at.
