The lower or mouth end of this opening is preffollowrng detailed description taken in conn erably formed a little larger than the inner end, Wlth fimwmg mmmg better to allow the brush to be quickly applied part of thls Speclficatlon; F to be undjerstood and removed from a binding post which is usual- 50 however, that the description and drawing are 1y tapered slightly. b w y of illusiretlons only and that changes In A somewhat similar washer is is positioned certain features of construction, combination against th outer end of th id t b l b h and a ran t f pa ts ay e s rted t back 15, and the lower annular edge portion of without departing from the spirit of the inventhe larger end of the holder is rolled in, as at 55 tion or the scope of the accompanying claims 19, upon the washer 18 to secure it and the tubular brush in position and against turning within the holder.

The upper end portion of the implement includes a closure shell 20 that is adapted to fit the smaller end portion 12 of the holder and to be secured thereto as by means of a thread or joint 21 as shown in Fig. 3. When this shell is secured to the holder, it serves as a handle for the operation of the tubular brush portion of the implement, while the larger cylindrical portion serves as the handle for the manipulation of the implement when the shell is removed and the internal brush used.

The .internal brush 22, which is used for cleaning out the hole 23 of terminal 24, see Fig. 2, is preferably made, as shown in the drawing, to include a spiral series of wire bristles 25 which are secured in that relation between two twisted wires '26 that extend centrally through the spiral series of bristles. The shank portion 27 of this brush is disposed out at a right angle, see 28, Fig. 5, and then bent around to form a ring 29 of a size to snugly engage the inner wall of the holder and the face of the washer 14 in a way to hold the brush against rotation independent of the holder. This produces a simple, practical and inexpensive form of internal brush, besides a simple means of securing it in the holder, yet in a way which will permit of its detachment and replacement should occasion require.

In Figs. 6 and 'l I have shown a somewhat similar construction of brush though the wires of the shank portion are disposed to form a loop 30 that is bedded or molded within a disk 31 of any suitable material, the annular edge of which is of a size to snugly fit into the lower end portion of the smaller end 12 of the holder, so as to be secured therein if desired, by a simple indentation or punch of the metal of the holder.

From the foregoing it will be apparent that I have produced a double ended brush. I have provided two distinct types of brushes in a single holder, one a tubular form of brush for cleaning external cylindrical surfaces, and the other an internal brush for cleaning inner walls of cylindrical surfaced and have mounted and provided the same with means whereby the said brushes may be entirely enclosed when not in use. The brushes are so arranged that total length of tool is reduced to a minimum, facilitating their use on batteries installed where clearances are limited. The same is designed to be inexpensively manufactured and adapted to be. sold at a small price and especially to form a convenient and needed tool for an automobile or motor boat tool kit.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a brush of the class described, the combination with a cylindrical holder, having an internal annular shoulder substantially mid-way of its length, a brush disposed central within and extending from one end of the holder and including a bristle supporting stem terminating at one end in an annular flexible supporting member seated against the inner wall of the holder, and means for securing said supporting member against said shoulder.

2. In a brush of the class described, the combination with a cylindrical holder having an internal annular shoulder substantially midway of its length, a brush disposed central within and extending from one end of the holder and including a bristle supporting stem terminating at one end in an annular supporting member that is seated against the inner annular shoulder of the holder, and means for securing said supporting member against said shoulder.

3. In a brush of the class described, the combination with a cylindrical holder having an internal annular shoulder substantially midway of its length, a brush disposed central within and extending from one end of the holder and including a bristle supporting stem terminating at one end in an annular removable flexible supporting member that is seated against the inner annular shoulder of the holder, and means for securing said supporting member against said shoulder.

4. In a brush of the class described, the combination with a cylindrical holder having an internal annular shoulder substantially midway of its length, a brush disposed central within and extending from one end of the holder and including a bristle supporting stem terminating at one end in an annular supporting member seated against the inner annular shoulder of the holder, a tubularform of brush mounted in the other end of the holder against said supporting member, and means for securing said tubular brush and supporting member against said shoulder.

5. In a brush of the class described, the combination of a cylindrical holder, one end portion of which is of a larger inside diameter than the other, forming an internal annular shoulder between said different diameters, an annular member seated against said shoulder, a tubular form of brush mounted in the larger end of the holder against said annular member, a sec--
