Reduce rig time by customizing magnet, scraper, and brush tools for your application The MULTIBACK combination casing cleaning tool comprises an integral magnet section to capture ferrous debris, scrapers to dislodge difficult-to-remove debris, and brushes to disturb the sheath and other fluid built upon the inner wall of the casing or liner.
Clean the wellbore so it's ready for completion The strong, flexible scraper lantern has a series of metal blades that provide the force to contact and scour the casing ID to remove mudcake and cement sheaths— including associated gunk and solid debris—and place them in suspension.
When the blades 3 and 4c are swung within the handle, the hammer head 13 can be readily used for hammering glaziers points, and can also be used for pulling tacks and similar securing elements.
It is also to be noted that when either of the blades 3 and 1 is swung open, it will overlap and friqtionally engage the head 13 to steady the blade, and the handle can be so held that the head 13 will press against the opened blade in order to better manipulate the implement.
Having thus described the invention, wha is claimed as new is i A compound tool comprising side pieces, a partition between the side pieces and provided at one end with a projection having a tack-receiving notch in one of its lateral edges, and a blade pivoted between the partition and one side piece and foldable into the handle, the free end of the blade constituting a fulcrum when the blade is open and when the notch is in use, the projection bearing against the side of the blade when the blade is open and when the free end of the blade forms a fulcrum, thereby to reinforce the blade.

The tool In may be formed of any suitable metal, such as structural steel or the like, which can be hardened to resist wear, especially at the end thereof which is sharpened to the point I2.
When this point I2 becomes dull with wear, the tool can be readily repointed by the simple expedient of grinding the surfaces I! In operation, the glaziers tool I0 of the present invention is easy and convenient to use and expedites the glazing of windows, as shown in Figures 4, 5 and 6.
Figure 1 illustrates use of the tool to remove old putty 20 from a conventional window sash 2i, for which purpose the tool is grasped in such manner that its open side extends in sliding relation over the inner corner of the sash, while its point I2 digs into the old putty 20 for easy removal of the same from the glass and sash as the tool is moved along the latter.
After removal of the old putty and after insertion of a new pane of glass, either side edge of the flattened portion it of the tool, when employed as illustrated in Figure 5, may be utilized to drive glaziers points 22 into the sash.
The flattened portion I3 of the tool also serves to shape the newly applied putty 23 in place, as illustrated in Figure 6. From the foregoing, it will be noted that the present invention provides a one-piece glaziers tool of a simple construction which greatly facilitates the work of a glazier. It is a tool which is characerized in that it is provided with a readily resharpenable putty removing point and with integrally formed means to drive glaziers points into position and to shape newly applied putty.
The tool is further characterized in that the putty removing and putty applying means are formed at opposite ends of a one-piece body member of a length suitable to constitute in itself a convenient handle for utilization of either end of the tool.
