Abstract
A belt sanding attachment tool suitable for use with a driver such as a bench drill, the belt sanding attachment tool being a complete unit and removable from the driver, and suitable for work operations such as grinding, polishing, sanding, finishing and the like. The belt sanding attachment tool has a rotating spindle providing a dual function of firstly providing the primary support of the whole belt sanding attachment tool to the driver, and secondly, providing rotary motion to a driving drum spaced from a second rotatable idler drum to direct and move an endless belt between the two drums. An outward biasing means is provided by way of a spring within a telescopic arm to keep the endless belt in tension.
Description
- This invention is an improved Sanding Belt attachment with replaceable sanding belts, to be used in a workshop machine such as a pedestal drill or a similar device.
- This invention provides a telescopic arm with a bearing assembly, drive shaft and drive drum at one end, and a tracking drum at the other. The telescopic arm has a spring fixed within it to provide a suitable force outwards towards the tracking drum.
- The bearing assembly has an upper and lower bearing through which the drive shaft is fixed.
- The upper end of the drive shaft is tightened into the chuck of a pedestal drill, and the lower end of the drive shaft has a threaded hole.
- The drive drum having a male threaded shaft at one end enables it to be fixed and tightened into the threaded hole in the end of the drive shaft. This situation allows the drive drum to be removed and exchanged for drum of a different profile.
- The bearings in the bearing housing are spaced at such a distance apart so as to provide vertical stability at the drive drum end of the telescopic arm.
- At the opposite end of the telescopic arm is the tracking drum. The tracking drum has one bearing in the upper end and one bearing at the lower end. These two bearings allow the tracking drum to rotate freely on its shaft which is fixed on the outer end of the telescopic arm. The shaft that the tracking drum rotates on is slightly extended at the bottom end so as to engage into one of the slots or holes in the drill press table thus creating a solid and stable positioning for the devise in the horizontal plane.
- When the device is attached to the drill press it presents the sanding belt at 90 degrees to the drill press table, allowing many variations of sanding profile to be achieved.
- Included and as part of the device is a suitably shaped metal backing plate with a flatted area. The top edge of the metal plate engages with and is fixed to the telescopic arm. The flatted area of the backing plate is positioned to be behind the working area of the sanding belt between the drive drum and the tracking drum. This enables a flat surface to be worked. The metal plate can easily be removed allowing gentle convex curves to be worked in the same area. At the drive drum end of the device concave sanding and shaping can be achieved. The interchangeable drive drum arrangement adds versatility.
- Included and as part of the device is suitably shaped narrow drive wheel that replaces The drive drum. The outer edge of the wheel has a radius and carries a narrow sanding belt to allow detailed concave sanding.

- REFERRING TO
FIG. 1 The device shows thetelescopic arm 1 with thebearing assembly 2 at one end and thetracking drum 3 at the other. Thebearing assembly 2 carries one upper bearing 2 a and one lower bearing 2 b. Theupper end 4a of the drive shaft 4 is tightened into the chuck of the drill press or similar device (referFIG. 7 .) Thelower end 4 b of the drive shaft 4 having afemale thread 4 c allows the male threadedend 8 a of thedrive drum shaft 8 of thedrive drum 5 to be fixed in and tightened. This arrangement allows a drive drum to be easily replaced with a drive drum of a different size and profile. - The
tracking drum 3 has an upper bearing 3 a and lower bearing 3 b to enable it to rotate freely on itsshaft 9. Theupper end 9 a ofshaft 9 is fixed to the outer end la oftelescopic arm 1. The lower end ofshaft 9 has anextension 9 b to engage into a hole or slot in the drill table of the pedestal drill or similar device (seeFIG. 7).The locking nut 9 c holds the tracking drum in its correct alignment. The compressedspring 1 b within thetelescopic arm 1 provides a suitable outwards force towards thetracking drum 3. - REFERRING TO
FIG. 2 Shows the bearinghousing 2 with one upper bearing 2 a and one lower bearing 2 b. The drive shaft 4 being fixed between the two bearings and with theupper end 4 a engaged into the chuck of the pedestal drill is the driving end of the device. Thelower end 4 b with threadedhole 4 c will except the male threadedend 8 a of thedrive drum shaft 8. Thedrive drum shaft 8 is permanently fixed to thedrive drum 5. - REFERRING TO
