3 Claims.

This invention relates to brush holders and combined brush holders and chisels.

Arc welding is now generally carried out by an electrode which is consumed in the welding process. This electrode ordinarily consists of metal and other materials which, after the weld has been completed, leaves a crust or slag on the work. It is necessary to chip and brush this slagaway.

It is the object of the present invention to provide a tool which can be used to chip this residuum of! the work and brush the weld clean. For this purpose I employ a tool which has a shank which supports both a chisel holder and also a brush holder. These tool holders are very simple and cheap in design but very eflicient for the purpose in view as will appear as the description of the details is bad.

In the drawing:

Fig. 1 is an elevation of the tool.

Fig. 2 is a cross section through the tool on the line 2--2 of Fig, 1. 1

Fig. 3 is a cross section through the tool onthe line 3.3 of F18. 1. r e

' The tool comprises a handle I having a rodlike shank 2 which flts into a chisel-holding head 3. 4 is a chisel which may be secured in said head by means of the set screw 5. The shank 2 passes through an opening 8 in the chisel-holding head and is anchored therein by the rivet 1. This rivet I also anchors the brush holder at one end thereof. The brush holder comprises clip is constructed of spring metal and comprises a pair of end members 8 and I II with turned-over portions 91': and Ilia adapted to flt over the wooden block H which forms the bristle-holding member of the brush. The sheet metal of the clip is turned over to form the'brackets [2 which straddle the top of the chisel-holding head and are secured to said chisel-holding head with the same rivet 1 which secures the shank in place. The sides of the clip are turned up to form wings I 3 which hold the wooden block of the brush from lateral movement. At the right-hand end or the clip the spring lugs M are turned out to form a pair of spring jaws which can straddle and grip the shank, as plainly shown in Figs. 1 and 3.

In order to fit the brush within the brushholding clip, all that is necessary is to place a tool, such as a screw driver, in the recess IS in the top of the end. In of the clip and pry it back to the dotted-line position shown in Fig. 1. Thereupon the brush may be removed and the new brush inserted, placing it under the turnedover end9a of the end wall 9 and dropping itbetween the turned-up wings I3. The. sprun out end IU of the clip is then allowed to spring back and engage over theother end of the wooden block of the brush. This makes a very simple and efi'icacious means for removably retaining the brush in .the holder. At. the same time it provides a holder that may be easily swung free from the shank of the tool by simply disengaging the-spring jaws 14 from the shank. This may be desirable in removing the brush from the shank or for other purposes.

The brush is supported on one side of the shank while the chisel projects out at right angles on the other side of the shank.

What I claim is: 1. A tool holder having in combination, a shank, a handle therefor and a brush-holding clip comprising a sheet metal member having spring end walls for removably holding the brush and provided with turned-over brackets, a fastening device passed through the brackets and the end of the shank to pivot the clip and a pair of spring jaws on the clip adapted to straddle the shank.

2. A tool for the' purposes described comprising, a handle, a shank and a brush-holdin clip, for holding a brush having a bristle-retaining block, comprising a stamping of spring steel having a channel portion and end portions with turned-over parts for engaging the bristle-retaining block seated in the said channel portion and one of the end portions having a recess by which a screw driver may be engaged with the end portion to pry it out to release the brush, the clip being also provided with spring lugs for securing it to the shank by simply for-sing the lugs over the shank. 4

3. A tool for the purposes described comprising,

' a handle, a shank and a sheet metal stamping of spring metal comprising two spring end portions having turned-over ends adapted to engage over the ends of the brush block. and having turned-over ears or brackets at one end for connection with the end of the shank and having near the other end a pair of, spring l ws eng ing around the shank, one of the ends being provided with a recess for the insertion 01' a screw driver or other tool to pry the end outwardly to release the brush and receive another.
