The present invention relates to woodworking machines and more'particularly, to an attachment for veneer taping machines,having for its principal object to provide' means for cutting the veneer in specified panels 'or sizes, whereby each panel, being so formed,

may be properly matched.

Veneering is usually manufactured in thin strips of varying lengths and widths, which are known to the trade'as being inV their.

ilitch. form and all of the strips of veneer out of the same flitch have corresponding markings as to gure, grain and texture. In the working up ofiiitch veneer, these strips are first cut to their proper lengths, according to the grain of the wood, then carried through a veneer jointer, which latter puts a perfect joint on the opposite edges of each strip and finally, these strips are placed edge to edgel and brought into intimate contact upon a taping machine, which latter attaches these separate pieces togetherbymeans of adhesive tape, in order to form a panel. These panels of veneer strips are than cut to the desired length or width Vtomeet the required form or pattern and in matching these panels, considerable-waste is incurred. [Accordingly, it is a further object f thepresent invention to provide an attachment for ordinary taping machines, whereby these veneer panels maybe readily cut and matched while upon the taping machine, thereby not only effecting a saving in the material used, but

also, a saving in labor as well as effecting `a.

perfect match of the panels or faces thereof. .A still equally important 'object of kthe present invention is to provide aveneer cutting and matching attachment of the character aforesaid, which may be easily' and readily applied to an ordinary taping machine and when installed thereupon, willnot in any manner, interfere with the working of the taping machine, but is readily accessible upon the latter and capable of cooperation therei Y brought into intimate contact, whereupon Other objects of the ,invention will beV 1n part obvious and in part pointed out hereinafter. v

In order that the invention and its mode ofi operation may readily understood persons skilled in the, art to which it appertains, I have in the accompanying illustrative drawings and` in the detailed following description based thereupon, set out one possible embodiment of the invention.

In these drawings Y Figure-l isa side elevation of the attachment embodying the present invention, when applied to an ordinary taping machine;

Figure 2 is a plan view of the same;

Figure 3 isa fragmentary view in side elevation of the adjustable graduated bar, a portion of the taping machine and the Vframe which carries the motor driven cutter of my improved attachment; v Figure 4 is a detaill plan view of the adjustable graduated bar and its locking arrangement; and

Figure 5 is a detail end elevation of the attachment embodying my invention and the table ofthe taping machine.

Referring now more particularly to the accompanying drawings, wherein like corresponding parts are designated by similar reference characters throughout the several views, I have herein'shown in fragmentary elevation, a portion of a conventional veneer taping maehinewhich consists of a wooden bed plate or table A, providedjwith an extension B arranged contiguous with one end.

thereof. The usual bracket arm C of the taping machine support or frame has attached to its outer end, a presser head D,

having arranged thereupon, the usual water container E, taper holder or reel F, which latter supplies the tape having adhesive'v the tape from the reel F is fed and applied to the edges of the contactingstrips of veneer in order that the stripswill be fastened together, but, of course, itis understood that the jointsof these veneer strips are perfectly matched before applying the tape thereto. These panels so formed upon the taping machine have, heretofore, been cut in sheets or shapes to meet the desired pattern, and in this matching and cutting of the panels, not only considerable loss of lthe material is experienced, but, considerable time and labor is necesasry to complete the same.

Vith the present attachment applied to taping machines, it is possible that as the panels are formed upon the bed plate A, they may be readily cut in the exact lengths or widths desired to meet almost any pattern, and that section severed will be used in formA ing the next succeeding panel.

The attachment embodying the present invention, comprises a pair of equally spaced and parallelly arranged channel bars 1 which have one end lixedly secured by means of the bolts 2 to the bracket arm C of the taping machine, and their opposite ends connected together and held in spaced relation by means of the spacing bolt 3. As will be noted in Figure 1 of the. drawings, these channel bars 1 project from the bracket arm C and are suspended above the base plate A, as well as its extension B of the taping machine. The inner faces of these channel bars 3 have secured thereto, rails 4 forming a trackway in which are adapted to freely travel, the ball bearing rollers 5, which latter support the cutter frame.

This cutter frame consists of a pair of spaced inverted U-shaped members or sections, each of which comprises a central tubular portion 6 in which are mounted the stub shafts 7 of the rollers 5. These shafts 7 are retained against rotation within the tubular members 6 by means of the set screws S.

Each section of the cutter frame is formed with a pair of parallel and depending rods 9 which are adjustably connected at their lower ends to a pair of longitudinally ei;n tending pl ates or bars 10, and secured to these bars 10 is the frame of a suitable electric motor 11. The armature shaft of this electric motor has keyed thereto, a cutting member l2 which may be a circular knife, or saw, and the purpose of which will be later set forth. The depending rods or arms 9 of the forward section of the cutter frame, have adjustably connected thereto, by means of the set screws 13, bracketsll which carry a housing 15 for the cutter 12, as is shown arranged therein. One edge of this housing 15 is provided with a lip extension 1G so that the veneer strips or panels may .be readily passed below the housing to the saw, which is arranged above the table A of the taping machine, whereas, projecting from the opposite side of the housing 15 is a projection 17 known to the trade as a splitter which latter is for the pun pose of keeping the veneer from binding during the cutting operation.

From the foregoing, it is obvious that this suspended cutter frame may readily travel in a longitudinal direction upon the bea-ms 1 and upon the setting of the motor 11 in rotation, the strips of veneer or panels, as they are fed below the housing 15, may be readily cut, but, in order to retain this suspended cutter frame in the desired position along the table A, I provide an adjustable locking device, which will now be described.

One of the depending bars 9 of the cutter' frame has adjustably connected thereto a bracket 19, by means of the set screw 18. This bracket 19 has a sleeve formed therewith, through which extends a rod E20 and this sleeve 19 may be retained in any adjusted position upon the rod 2O by -means of the set screws 21. This rod has suitable graduations thereon, which as shown in the drawings, range from 1 to 50 and indicate inches, but it is to be here understood that these graduations may be in fractions of inches, as conditions or preference may dictate.

Secured to the rod 20, but adapted to oscillate thereupon, is a sleeve having a handle 22 formed therewith and which handle is provided with a lug projection Q3 which latter is adapted to be seated within any one of the notches of the rack bar 211. This rack bar has one en d secured by means of the bolts Q5, to the frame of the presser head, whereas,

its opposite end is connected by means of the bracket 26,to the bracket arm 8 of the taping machine. Depending from this rod 20 and detachably Yconnected thereto by means of the nut 27, the latter engaging the threaded end of the rod 20, is a depending plate 28 forming a guide and indicator, and the lower end of this guide plate 28, as will be noted from Figure 1 of the drawings, projects adjacent the upper face of the bed plate A of the taping machine.

The handle 22 projects from one side of that side of the taping machine to which the operator stands for controlling the same, and the operator, by lifting upwardly upon this handle 22, will release the lug 23 from engagement with the rack bar 24, whereby upon movement of the rod 20 in either direction, the cutter frame will be caused to travel within the channel beams 1, and when it has assumed the described position along the base plate A of the taping machine, the handle 22 may be released, whereupon it will again be seated within one of the notches of the rack bar 24: and retained against further longitudinal movement. Also, the cutter frame is retained in the desired position upon the rods 20, by means of the set screw 21 whereby the panels of veneering of various lengths or widths, or that which equals the distance between the indicator 28 and the saw blade 12, may be readily cut when placed upon the table A of the taping machine, and the motor to which the saw is attached, set in motion.

The strips of veneer, after they have been passed through a ointer, are placed upon the table A,`e'dge to edge, and brought into intimate contact. The contacting edges of the veneer strips are passed below the presser .head of the taping machine, whereat they are glued together by the tape, in the customary manner. These strips or separate pieces of veneering which have been joined together by means of the tape form a sheet of veneering until one edge thereof contacts with the indicator 28. Itis from this sheet of veneering the panels `of a known or required form or pattern are cut. The cutting blade l2 should be adjusted and retained in this adjusted position upon the rod 2O so that the distance between this cutting blade and the pointer 28 will be the same vas the width of the pattern of which the panels of veneering follow. l/Vhen this sheet of veneering which has been formed uponthe bed plate A is of greater Width than the distance between the cutter l2 and the pointer 28, the motor 1l is set in operation whereupon'the cutter 12 will sever from the sheet of veneering so formed, a panel which is equal to the distance between the cutter and the pointer 28. That portion or section of the sheet of veneering which has been severed, will still have one edge with a perfect joint thereon, to which,

may be secured, by means of a taping machine, additional strips of veneering until a second sheet is formed.V After the cutter frame has been locked in the proper position upon the rod 20, it is obvious that duplicate panels of veneering may be readily cut from the sheets as formed upon the bed plates, and' each panel will be properly matched and cut in the desired width, while upon the taping machine. That portion of the veneering which has been severed from the sheet formed upon the taping machine as heretofore been wasted, but with my improved attachment, these sections or pieces which have been severed from the sheet can still be used in forming the next panel, thereby not only saving in the material'used, but also in the labor required to properly out and match these panels. Y

Manifestly, the construction shown and described is capable of many modifications and those modifications that are within theV scope of the claims, I consider within the spirit of my invention.
