This invention relates to means for designing and'la-ying out rotatable shaping tools having plane rectangular bodies and whose end andbottom edges may be utilized for 5 effecting shaping cuts, and hasfor its object to provide a novel template, having the same length, breadth and area as the tool blanks, upon which the design for a tool mayb-e first laid outby inscribing the pattern and then 51o cutting away portions of one end and the bottom edge. The top edge of the ,template may be formed Ywith a right angle flange that overlies the top'edge of the tool blank, and adjacent said ange the body of the template i5 may be formed with lugs or ears toengage sockets in thetooll blank forholding the template and blank in coincidence while the pattern for ,the tool is being traced and ,inscribed o n one face yof the blank. After the 1,29 patternis inscribed upon oneend of the tool blank, the template may be reversed and mounted upon the opposite face of the blank, to enable the -tool-maker` to trace and inscribe thepattern upon the opposite end portion of the blank, after which the blank maybe cut away-by a profiling tool, ground, and finally sharpened to conform -tovthe said pattern. By this methodand means of designing, laying out, and transferring the patterns, shaptsi; ing tools of. this particular type may be truly balanced, and readily and accurately conditioned for performingplaimpas well asornamental shaping work. y The various features and parts of the in- 1552 vention will be understood from the detailed description which follows, and by reference to the accompanying drawing, in which- Figure 1 is a side elevation of a shaping tool blank, to which my improvement is ap`v 401 plied.- Fig. 2 is an endelevation of the same..

Fig. 3 isa front side elevationof the template blank showing the profilemarkings, andthe retaining flange andlugs. Fig. 4 is an end F1g.,.5 1s -an eleva-:

elevation ofthe same. y tional view showing l the blank template mounted upon andinter-locked with thetool blank, also showing `patterns for different styles of shaping, inscribed upon the checker field. Fig. 6l is an end elevation of thesame.

59.; Fig. 7 is a horizontal section taken on linev 7-7 of Fig. 5,showing the lugs in theretaining position. Fig. S is a side elevation of a tool blank showing a pattern tracedfrom a prepared template. Fig. 9 is a side elevation of a similar toolfblank, having its oppoV site ends cut to aV modified"patterinin the act of shaping a piece of work. Fig. l() is still another tool blank, whosebottom edge is formed to shape a rosette, the ends of this tool being formed to effect plaincuts. And Fig. llis a vfront face view of theteinplate, showing ythe llower right corner cut yawa Yto the` shape of' the pattern/outlined in Figs. 5 and`8.ff x n n In the drawing, 2 represents a plane rectangular ,tool blank having its top edge slotted at 2( 'to provide 1 upwardlyfacing tongues,`,as 2te-26.' V3represents.'the plane rectangular body ofthetemplate having the same length and breadthy but preferably being ofV thinner gage than the blank 2, so that when the template is mounted upon the blank, the said parts exactly coincide or register, except at the top where the template is formed with a right angle flange 3, that is adapted to overlie the top edge` of the blank 2 for preventing gravitative movement of thetemplate relatively to the", blank. Below the flange 3",.the'b0dy 3 isprovided with similar' lugs or ears 3a, which are punched and bent to form stops that project beyond therear face of the body, the same as the flange 8. The lugs 3a are disposed perpendicular `to the plane of the flange 8 andare spaced to correspond to thespacing ofthe edges 2c of the tongues 2a `to prevent lateral or endwise movement of theparts 2 and 3 (see Figs. 5 and 7 Substantially one-half of the area of one planeface ofthe template is stamped or otherwise scored with a checker pattern 3c" simulating the ordinary'V profile paper em-y ployed by engineers and others for accurately laying out lvarious designs, as may be understood .bythe ornamental patterns shown at dand' 3e in the lower right corner of Fig. 5. In practice, the tool designer inscribes the template Btwith a pattern for a new tool, fork example, as shown at 3d in Fig. 5. His next step is to cut away kthe template 3 alongy this inscribed line, as shown in Fig. l1. The telnsoA plate may then be mounted, as shown in Fig. 5, upon a tool blank, to enable the designer to trace and inscribe the pattern 3d, for example, upon the right end, .as 2d, of the blank, as shown by the full lines in Fig. 8. He next removes, reverses and mounts the template upon the opposite `face of the tool blank and repeats the tracing and inscribing of the same pattern on the latter face, as shown by the dotted lines in Fig. 8. The template may then be laid away for future-use. The tool blanks are nally operated upon by `a profiling tool, A

ground, and sharpened ready for effecting shaping cuts according to the various patterns, as maybe understood by consulting Fig.`9. In the latter view, the toolV 2f isy fashioned to effect a slightly modified cut, as vcompared withFig. Y8but the principle involved is s'ubstantiallytheV same. The tool in Fig. 9

is shown in the act ofl shaping a piece of w0rk,'as A,to impose an integral molding, as A along one corner` of the work. Fig. l0 shows a tool 2m which has been fashioned to shape al rosette,las B, the pattern for the rosette having beenoriginally laid yout upon the checker portion` of a' template (not shown), and afterwards transferred to the Y tool, as explained'. In the tool 2m', however,

' the ends .2d-2e are preferably leftplain, and' may be sharpened-in order to facilitate sinkingthe tool intofwoodor other material in'whichthe rosette 'is formed.,

AI claim, is-

Inf practice,the tool blanks 2, as well 'as the template blanks 3, yare prepared, andsuppliedv tothe users,A by the' manufacturer of the shapling machines, and the users ordinarily do their own tool :designing and' conditioning, as explained'. By this arrangement, the manufacturers of l furniture, :planingmill vprodnots, or the like,` may create regular orV special Y designs, and the templates therefore may be kept in stock, and may be used repeatedly, for reproducing thevarious shaping patterns. y Having thusdescribed my invention, what l. A template rectangular body,` a portion of one plane face ofl said body being inscribed with a checker ,arrangement of lines, one edge of said body beingv bent and' adapted to overlie the corresponding edge of a tool blank, said body be-Y low said bend being formed with lugs adaptled to cooperate with said bent edge for interak p for transferring shaping, patt-ernsto tool blanks comprisinga plane-A with a flange adapted to overlie a slotted edge of the tool blank and being formed below said flange with lugs adapted to engage said slots to inter-lock the body with the tool blank, said template being adapted to be mounted rston one side and then on the-other of a tool blank to enable the pattern to be transferred in like manner to both ends of the blank. f A

'3. A template for laying out designs upon shaping tool blanks comprising a plane angular'bodyfhaving a flange at one edge adapted to overlie the corresponding margin of the tool Yblank and having a plurality of stop lugs to interlock with the blank below said flange tov hold the template and blank in true coincidence, one facev of saidbody being inscribed with a criss-cross arrangement of profile lines, said lines extending Yfrom the middle towardsl one end of thebody and adapted when .inscribedv with the outlines of a tool pattern to be cut away along said lines to enable a tool-maker to inscribe the pattern upon the opposite faces of the tool blank by the reversing of thertemplate, substantially as described. 'n 1 v 4. A Itemplate comprising a plane rectanfgular body having' theV same? length and breadth as a toolblank, a portion of one face of said body being ruled to provide a checker field to aid in accurately designing the patterns for shaping tools, 'said bo'dybeing adapted to be cut away along the lines of a pattern andto'be mounted upon-atool blank to enable the tool-maker to trace and inscribe thepattern upon saidblank, one margin of said body being bent to formafiange adapted to overlie the corresponding edge of the tooll blank and. said bo'dy'also having aV plurality of stop lugs to inter-lock and hold said body and blank in coincidencewhile thepattern lying'within the limits 'of' the checker field is being inscribed -upon the Aopposite faces of the tool blank. f

5. A template for tracing shaping patterns upon tool blanks having sockets in one edge,-

comprising a substantially plane body having the same length and breadth assaid blank, one margin of saidy body being formedwith a flange adapted to overlie the socket-edge of the blank,` said body belowsaid' flange be# ing punched to provide stop lugs that faccina' the same direction as saidgflange, said lugs,V being adapted to engage said sockets and toi' cooperate with said flange for interlocking the template withV the tool blank to effectthe registering ofsaid'parts when V they are brought together, fone -end portion 'of said body being adapted -tobecut away 'to conform to the outlineof a shaping pattern to enable a tool-maker to inscribe said out-line upon the opposite faces of the tool blank by the reversing of the template.
