Abstract
Abstract A routing template assembly has been devised which is specifically adaptable for routing out slots of different widths in panels, boards and the like, such as for example, in forming slots in side wall supports for insertion of shelf sections. The template is characterized by a slotting guide which is adjustable in width depending upon the width of slot to be formed, adjustment being accomplished by setting the spacing between spaced parallel guide edges of the slotting guide to correspond to the desired width of the slot plus the diameter of the router guide bushing less the diameter of the routing bit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
242 words
In apparatus for routing elongated slots in a workpiece in which a router bit is adapted to be inserted through a guide bushing, the combination comprising: a stationary frame including a workpiece-receiving area and a stationary guide in overlying relation to the workpiece-receiving area in which the guide edge extends in a direction parallel to the intended length of the slot to be formed; adjustable template means mounted on said stationary frame including a second adjustable guide edge disposed in coplanar spaced parallel relation to said stationary guide edge, said stationary and adjustable guide edges defining guide opening means therebetween in overlying relation to the workpiece for guiding the router guide bushing along the guide edges to form a slot or predetermined width in the workpiece; and adjustment means between said adjustable template and said stationary frame to position said adjustable guide edge with respect to said stationary guide edge at a spacing corresponding to the intended width of the slot to be formed in the workpiece plus the diameter of said guide bushing less the diameter of said router bit, said adjusting means including adjustable sizing means between said adjustable template means and said frame movable a first distance independently of said adjustable template means and being further movable a second distance in the same direction as the direction of movement for the first distance to cause movement of said adjustable template means over a distance corresponding to the second distance
Claim 2

In apparatus for routing elongated slots in a workpiece in which a router bit is adapted to be inserted through a guide bushing, the combination comprising: a stationary frame including a workpiece-receiving area and a stationary guide in overlying relation to the workpiece-receiving area in which the guide edge extends in a direction parallel to the intended length of the slot to be formed; adjustable template means mounted on said stationary frame including a second adjustable guide edge disposed in coplanar spaced parallel relation to said stationary guide edge, said stationary and adjustable guide edges defining guide opening means therebetween in overlying relation to the workpiece for guiding the router guide bushing along the guide edges to form a slot or predetermined width in the workpiece; and adjustment means between said adjustable template and said stationary frame to position said adjustable guide edge with respect to said stationary guide edge at a spacing corresponding to the intended width of the slot to be formed in the workpiece plus the diameter of said guide bushing less the diameter of said router bit, said adjusting means including adjustable sizing means between said adjustable template means and said frame movable a first distance independently of said adjustable template means and being further movable a second distance in the same direction as the direction of movement for the first distance to cause movement of said adjustable template means over a distance corresponding to the second distance
Claim 3
Dependent Claim
40 words
In apparatus according to claim 1, said stationary frame having a workpiece-receiving area defining a longitudinal guide path for movement of an elongated workpiece lengthwise therethrough, said stationary and adjustable guide edges extending transversely of the length of the workpiece.
Claim 4
Dependent Claim
233 words
In apparatus for routing elongated grooves in a workpiece in which a router bit is adapted to be inserted through a guide bushing, the combination comprising: a stationary frame including a workpiece-receiving area in which the guide edge extends in a direction parallel to the intended length of the slot to be formed; adjustable template means mounted on said stationary frame including a second adjustable guide edge disposed in coplanar spaced parallel relation to said stationary guide edge, said stationary and adjustable guide edges defining guide opening means therebetween in overlying relation to the workpiece for guiding the router guide bushing along each of the guide edges to form a resultant groove of predetermined width in the workpiece; and inner and outer adjustment means between said adjustable template and said stationary frame, said inner adjustment means disposed between said adjustable template means and said frame, said outer adjustment means defined by adjustable sizing means on said adjustable template means movable a first distance independently of said adjustable template means corresponding to the diameter of said router bit and being further movable in the same direction as the first distance for a second distance to cause corresponding movement of said adjustable template means when said inner adjustment means is loosened to permit movement of said adjustable template means a distance corresponding to the width of the groove less the diameter of said router bit.
Claim 5
Dependent Claim
233 words
In apparatus for routing elongated grooves in a workpiece in which a router bit is adapted to be inserted through a guide bushing, the combination comprising: a stationary frame including a workpiece-receiving area in which the guide edge extends in a direction parallel to the intended length of the slot to be formed; adjustable template means mounted on said stationary frame including a second adjustable guide edge disposed in coplanar spaced parallel relation to said stationary guide edge, said stationary and adjustable guide edges defining guide opening means therebetween in overlying relation to the workpiece for guiding the router guide bushing along each of the guide edges to form a resultant groove of predetermined width in the workpiece; and inner and outer adjustment means between said adjustable template and said stationary frame, said inner adjustment means disposed between said adjustable template means and said frame, said outer adjustment means defined by adjustable sizing means on said adjustable template means movable a first distance independently of said adjustable template means corresponding to the diameter of said router bit and being further movable in the same direction as the first distance for a second distance to cause corresponding movement of said adjustable template means when said inner adjustment means is loosened to permit movement of said adjustable template means a distance corresponding to the width of the groove less the diameter of said router bit.
Claim 6
Dependent Claim
54 words
In apparatus according to claim 3, said stationary frame having a workpiece-receiving area defining a longitudinal guide path for movement of an elongated workpiece lengthwise therethrough, said stationary and adjustable guide edges extending transversely of the length of the workpiece, there being inner and outer adjustment means at opposite ends of said guide edges.
Claim 7
Dependent Claim
38 words
In apparatus according to claim 3, said outer adjustment means being defined by a stationary sizing block and an adjustable sizing block movable in a direction toward and away from said stationary block normal to the guide edges.
Claim 8
Independent Claim
162 words
The method of routing a slot in a shelf unit and the like, comprising the steps of: a. placing a template having an adjustable guide opening therein over a workpiece in which a slot of the desired width is to be formed; b. setting the width of the slot in one direction of movement between the guide edges to conform to the diameter of the guide bushing for a router bit to be employed in forming the slot; c. increasing the width of the slot in the same direction of movement as in step (b) an additional distance to conform to the width of the shelf to be inserted into the slot less the width of the router bit; d. fixing the spacing between the guide edges; and e. advancing the router within the guide bushing along each guide edge with the router bit extending through the opening formed therebetween to form a resultant slot of the desired width in the workpiece.
