I'LANING TOOL.
Application filed April 28, 1924. Serial No. 709,467.
My invention relates to finishing or dressing tools and its primary object resides 1n providing a tool of very simple constructlon which is particularly adapted for the use of joiners, carpenters, cabinet makers and other artificers to smooth the edges of boards and other work-parts at a true angle to a guiding surface with which the tool engages.
Another object of the invention 1s to provide a tool of the above stated character which in association with a stock or holder of suitable design, comprises an abrasive element which is readil adjustable to present a fresh surface t ereof to the work when the portion priorly used is incapacitated by wear or by the adherence of abraded matter.
Another object to provide in combination with the tool, removable and interchangeable parts which adapt it for use in smoothing and olishing rounded and rabbeted edges; a urther object is to provide a tool of the above described character which is easily adjusted to fit boards or other parts of different thicknesses or widths, and still other objects reside in details of construction as will fully appear in the course of the following description.
An embodiment of my invention has been illustrated in the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views and in which Figure 1 represents a perspective view of the finishing or dressing tool in an inverted position;
Figure 2, a transverse section of the tool 111 its operative position to the work, taken in a plane indicated by the line 2-2 in Figure 1 Figure 3, a similar section in the plane designated by the line 33 in Figure 1;
Figure 4, a cross section of the tool showing its ada tation for smoothing edges of half-round orm;
Figure 5, a similar view showing the tool inits modification for planing quarter-round edges;
Figure 6, a fragmentar perspective view of one of the parts emp oyed to adapt the tool for the uses illustrated in Figures 4 and 5;
Figure 7, a fragmentary perspective view of an abrading element differing from that shown in the other views and adapting the tool for use in smoothing half-round edges;
Figure 8, a transverse section through the tool illustrating the method of using the abrading element shown in Figure 7;
Figure 9, a similar section showing an abrading element of the type depicted in Figure 7, modified for use in smoothing quarter-round edges;
Figures 10 and 11, similar cross sections showing modifications of the abrading element for dressing edges of boards formed for groove-and-tongue connection; and
Figure 12, a cross-seetion showing means for clamping the abrading element in place.
Referring more specifically to the drawings, the reference character 5 designates the stock or holder of the tool, comprising an elongated top or hearing member 6, a guide member 7 fixed upon the bottom surface thereof and an adjustable guide member 8 provided with bolts 9 which project loosely through transverse slots 10 of the top.
The guide members extend longitudil'lally of the top at right angles to its lower or bearing surface and in parallel relation to each other and they are slotted as at .12 for the insertion of an abrading element in sheet form which in the ordinary uses of the tool. lies fiat against; the under surface of the top as shown in Figures 1, Q and 3 of the draw- 'ings.
The abrading element hereinbefore referred to consists in the form of the invention showing in Figures 1, 2 and 3 of a sheet- 15 of sand-paper, emery cloth or other similar material which fits loosely through the spaces 12 which separate the guide-members from the surface of the bearing members.
In the operation of the tool, it is placed over the edge of a board or other work-part 16 as illustrated in Figure 2, with its guidemembers slidably engaging upon the sides thereof. By moving the tool lengthwise of the board under pressure of the hand upon the top 6, the abradin element smooths the edge in a plane at rigdit angles to the sides engaged by the guide-members and after the active port-ion of the element becomes worn or clogged'by the abraded wood particles, a fresh portion is readily substituted for the other by sliding the sheet through the slots of the guides.
It will thus be evident that by the use of my invention the edge of a board is readily and accurately dressed,- trued and squared to produce a perfect joint in connection with other similarly prepared parts of the work; that the labor may be expedited atwill by feeding the abrading element through the slots of the guide members; that for many purposes the tool provides an eiiicient substitute for the ordinary plane at present in common use, without the necessity of adjusting and sharpening knives or chisels; that the adjustability of the movable guide member adapts the tool for use on work of ditle'rent widths; and that but little practice is required forthe etlicient operation of the tool even by persons inexperienced in carpentry.
The tool may be composed of wodd or metal and it will be apparent that several variations may be made in the form of its parts and the method of their co-operative connect-ion within the spirit of the invention as herein defined. V
The tool may be adapted for quicker or coarser work by substituting for the sandpaper or emery cloth of the above described form of the invention, a flat metalplate having its surface toothed, ribbed or otherwise sharpened as shown in Figure 7, and I desire it understood that in the term abrasive element as employed in this description and the hereunto appended claims, is embraced any abrading or cutting substance in sheet- 'fOlll'l or in the special form required for smoothing rounded or broken-line edges as will now be explained.
Referring first to Figured of the drawings, two templets or formers 18 are placed in the space between the guide members to conjointly provide a bearing for the sandpaper, in conformity with they semi-circular edge of a board 19. The templ'ets may be made of sheet metal as shown in Figure 6 and theyare provided with flanges 20 which are inserted in the slots of the guide members to hold tl'i'e-teinplets in place.
The sheet of sandpaper is passed through the supplemental slots ltof the guide members and the tool is operated as before;
in the modification illustrated in Figure 5, but one insert is used to adapt the tool for use in smoothing the quarter-round edge of a board 21 and the sheet of sandpaper is in this instance passed through the supplemental slot of one of the guide members and through the regular slot of the other member.
In order to maintain the contact between the guide members of the tool and the sides of the work, the inserts are let into shallow recesses 28 in the inner surfaces of the guide members as plainly shown in Figurest and 5.
Figures 8 to 11 inclusive illustrate a method of smoothing edges of different shapes by means of correspondingly formed metal plates of the type shown in Figure 7. Thus in Figure 8 a metal plate 17 placed in the supplemental slots of the guide members, has a ridge 22 of semicircular section which engages the half-round edge of the board 19 and in Figure 9 a plate 28 is ollsct by a bend 28 of (punter-round section to engage the correspondingly formed edge of the board 21, the portions of the blade at opposite sides of the offset being inserted respectively in the supplemental slot 14 of one of the guide members and the slot or space 12 of the other member.
The plate 29 shown in Figure 10 has a ridge 24 of channel section to smooth the faces of the grooved edge of aboard and its portions at opposite sides of the ridge pass through the spaces 12 of the guide members to engage the surface of the edge at opposite sides of the slot. In Figure 11, a plate 30 passed through the supplemental slots of the guide members is formed similarly to that shown in Figure 10 to engage the edge faces of a board 26 provided with a tongue 27.
The plate shown in Figure 8 has been extended at opposite sides of its rounded portion to plane wider boards with rounded tongues.
,In Figure 12 of the drawings has been illustrated a simple appliance for clamping the abrasive element in place for the purpose of avoiding lost motion during operation of the tool. The appliance as shown consists of a spring-urged pin ill which is movably mounted on one of the guide members to forcibly engage the abradant sheet and thereby oppose its movement upon the surface of the bearing member 6. It will be understood, however, that other means may be employed to produce the same result, as for example, by omitting the slot in the movable guide member and clamping the member upon the abradant sheet by the nuts on the bolts.
What I claim and desire to secure by Letters Patient is:
1. A dressing tool comprising a bearing member, slotted guide members spaced there- 'on, an insert in the space between the members substantially conforming with the work, and an abradant element passing through slots of the guide-members and engaging with the insert.
2. A dressing too] comprising a bearing member, slotted guide-members spaced there- 5 on, an insert in the space between the members substantially conforming with the work and having a flange in a slot of one of the guide-members, and an abradant element passing through slots of the guide members and engaging with the insert.
In testimony whereof I have afiixed my signature.
CARL G. KROOK.
