Abstract
A tool-supporting bench for use with electrically-powered tools such as circular saws, routers, planes, sanders or grinders has a workpiece- supporting surface (19) and two parallel rails (7 & 10) mounted on a vertical frame member (4) which extends from the surface. A cradle (2) in which the tool can be mounted, e.g. by means of a mounting plate, is slidably mounted on the rails so that it can be moved over the surface in an accurately-controlled way. Rails perpendicular to the first rails can carry the cradle for cross-cuts, and arcuate working can be achieved using a part-circular rail (24). <IMAGE>
Description
SPECIFICATION
Tool Supporting Bench
This invention relates to a tool-supporting bench for use with electrically-powered tools such as circular saws.
Portable circular saws may be mounted on a work bench by the use of a mounting plate to which the saw is attached. Such mounting plates facilitate the use of the saw on a portable combined work bench and vice. Whilst such an arrangement permits, with careful use, the making of saw cuts of adequate precision for many purposes, accurate crosscutting of long pieces of wood requires careful marking and manipulation during cutting. A further disadvantage of such an arrangement is that the cutting sector of the circular saw blade is directed upwards, and thus care must be taken that sufficient downwards pressure is exerted on the workpiece to ensure that it is not displaced during the cut. This downwards pressure must be exerted in such a way that theoperator"s hands are kept well clear from the saw blade.
Saw benches used in timber yards, for example, may avoid some of these problems by mounting a circular saw to slide along a rail or rails above a cutting bench. The cutting sector of the saw blade is thus directed generally downwards to cut timber located on the bench.
The bench may be provided with stops to locate the timber enabling accurate cuts to be made quickly. This type of saw bench has a fixed saw, and can therefore not readily be used for other operations, such as planing or routing, and is typically so constructed as to be a permanent fixture rather than readily transportable.
According to the present invention there is provided a tool-supporting bench for use with an electrically-powered tool, comprising a workpiece-supporting surface, a rail located above said surface and parallel thereto, and a cradle slidable along the rail and arranged to carry an electrically-powered tool whereby the tool may be guided across the surface.
Two parallel rails may be provided and the cradle may have bearing members which slidingly engage the rails.
Preferably the rail or rails is or are supported by a vertical frame member upstanding from the workpiece-supporting surface, and the bench may be adapted to fold up to reduce its bulk for storage or when being transported, thus making the frame particularly useful for amateur woodworkers, who may have limited space available, and for builders, enabling precision joinery to be carried out on a building site.
The bench may have two mutually perpendicular rails or sets of rails, the cradle being slidable along either rail or sets of rails to enable both cross cuts and ripping cuts to be made, for example, when a circular saw is being used in the cradle.
The cradle may be adaptable to receive alternatively a circular saw, a planar, a sander, a grinder, a router, or any other such powered tool.
This adaptability may be achieved by providing in the cradle adjustable supporting bars for the tools or means for receiving a mounting plate for each tool, the plate being adapted to mount a particular type of tool.
The bench is suitably formed of metal tubing or box section members and/or angle section members. The workpiece-supporting surface may be defined by a framework or by a wood or other material sheet fixed to the framework.
Reference is made to the accompanying drawing in which: Figure 1 shows, a partially cut away, a toolsupporting bench according to an embodiment of the invention; and
Figure 2 is a partial view of the bench shown in
Figure 1 with a modification.
The tool-supporting bench comprises a main frame 1, which is shown supported on trestles for use at a building site for example, and a movable cradle 2. The main frame may alternatively be mounted on an existing work bench, in a workship for example, thus avoiding the need for trestles.
The main frame 1 is formed principally from box section steel tubes and angle section steel strip and has a base sub-frame 3 and a back subframe 4 upstanding from the base sub-frame 3.
Five vertical rectangular supports 5 are hinged to the back sub-frame 4 and are swing out perpendicular to the back sub-frame 4 to support a top rail-support sub-frame 6 which is also hinged to the back sub-frame 4 and may be folded downwardly, as indicated by the broken section 6a in the drawing. The supports 5 and the rail-support sub-frame 6 may be connected by means of pins, bolts, latches or any other suitable connection.
A longitudinal fixed rail 7 is secured to the free edge of the top sub-frame 6, and transverse fixed rail 8 runs along a cross-member 9 of the top subframe 6. A detachable longitudinal rail 10 may be secured to the lower free ends of the vertical supports 5 when these supports are fixed
perpendicular to the back sub-frame 4. A
detachable transverse rail 11 may be secured to a
central support 5a to enable the cradle 2 to be
used for cross-cuts.
The cradle 2, shown in Figure 2, is constructed
of angle section metal members and has an
adjustable frame member 12 which partially telescopes within two side members of the tool
carrying frame member 13. Locking screws 14
are used to clamp the adjustable frame member
12 relative to the tool-carrying frame member 13.
On the uppermost bar 1 2a of the adjustable frame
member 12 is mounted a runner bar which is
arranged to run along the fixed rails 7 and 8. On
the opposite face of the tool-carrying frame
member 13 is slidably mounted a mounting bar
1 6 which also has a runner bar which can run
along the lower detachable rails 10 or 1 1. All the
rails contain ball races on which the runner bars
bear. The position of the mounting bar 16 can be
fixed by means of screws (not shown). The tool to
be used is mounted within the tool-carrying frame
member 13. The size of the frame member 13
relative to that of the tools which it is to be used
is such as to ensure that the operator's hands
need not be placed near the tool, increasing the
safety of its use.The tool is located by means of
an adjustable bar 18, and provision may be made
in the frame member 13 for mounting different
shapes of bar or a mounting plate to which the
tool may be secured.
The base sub-frame 3 is provided with a
workpiece-supporting surface 19 of chipboard
sheet upon which are located an adjustable
wooden fence or stops (as shown) against which
the workpiece may be located during the cutting
or other operation being carried out on the
workpiece.
By positioning the parallel rails of a pair of rails
in different horizontal and vertical planes from one
another, the rigidity of support given to the cradle
is very high, ensuring high accuracy of movement
of the cradle and thus of the resultant cut, for
example, in the workpiece.
In addition to the rails described above, other
rails may be provided in the bench to permit
working at a variety of different positions along its
length. This may also permit additional cradles to
be used, thus enabling different operations to be
performed at different parts of the bench without
having to change tools in the cradle or transfer
the cradle to a different set of rails. As shown in
Figure 2, a pair of rails 20 and 21 is mounted on a
frame 23 which is hingedly mounted to the back
sub-frame 4 and additionally guided by a semi
circular guide rail 24. The rails 20 and 21 mount a
smaller cradle 25 which may carry a router, for
example, enabling routing of a workpiece at a pre
determined radius through to 1 800.
The bench 1 may be used to support a plurality
of different powered tools. In addition, as shown
in Figure 1, a non-sliding cradle 26 can be
mounted between adjacent supports 5 using
slidable brackets 27 whereby the height of the
cradle 26 relative to the surface 19 may be
selected. A router, sander or like tool may be
mounted in the cradle 26, permitting a workpiece
to be worked on by propelling the workpiece
under the cradle 26 on the surface 19. The cradle 26 may also be used to mount a lathe.
The back sub-frame 4 or the supports 5 may be used to mount detachable round tubular columns for use as drill stands, and other tools may be hung on the bench when not required, for example on hooks engaged in a sheet of perforated hardboard or the like, secured to the back sub-frame 4. Electric power sockets may be provided at suitable locations on the bench, the necessary wiring running within the box section members, a single connecting cable then being used to link the sockets to an electric power supply. A wood-working vice 28 is shown in
Figure 1 mounted on one end of the bench.
The bench permits accurate working of a workpiece by electrically-powered tools, particularly of the type which are intended to be hand-heid, or at least portable. For example, saw cuts may be made at any desired depth in the workpiece.
