T 0 all ywhom z'l may concern Be it known that I, VILLIAM POTTER, a citizen 4of the United States, and residing at New York city, in the county of New York and State of New York, have vinvented certain new and useful Improvementsv in foodworking Machines, of whichthe following is a specification', such as will enable' those skilled in the art to which it appertains to make and use the same. f

This invention relates to woodworking machines and particularly to machines of this class designed for-the? purpose of reproducing in a workpiecei a predetermined contour from a sample or model in thepro; duction of molding strips, finishing strips 4and various other kinds and classes of woodwork, and also toa machine of this class designed to produce dado work, Vand the object of the invention is to provide a machine of the class and for the purpose specified, which by reason of its construction will produce the desired resultsl in the most eff-ective, simple, accurate and efficient manner,

and with this and other objects in view, the

invention consists in a machine ofthe class specified which is simple in construction and operation,'and eliicient in use andwhich is .constructed and operated as-hereinafter described and claimed. Y.

The invention described f and claimed herein is an improvement on that shown and described in a prior applicationl liled 'June 13, 1922, Ser. No. 567,942, and is fully disclosed in the following specification of which the accompanying drawing forms a. part, in which the separate parts of -my iniprovement are designa-ted by suitablereference Characters in each of the views, and in 'whichz-n i F ig. 1 is a front machine. l .l

Fig'. 10 is a diagrammatic view of a part of the construction'shown in Fig. 9 of the drawing. Y i

Fig. 11v isapartial section Von thev line .11-11 of Fig. 9; and

bottom table members 15 and 16 joined tothe side members 14 Vby longitudinalrods 17 as clearly shown in Figs. 1, 3 and 9 oftheV drawing, and the lower ends of the side memberslt are preferably .braced by other the drawing.

' The top table lmember in the construction shown is composed of three forwardly and backwardly directed units 151,' and one of lthese units is located centrally of the frame and the othertwoat'the opposite sides vof the frame. The table memberV 16 is similar- 'ly formed and viscomposed of separate units` 16a spaced in `the manner ofthe units 15a.

Mounted upon the vbottom table member A16 or the separa-te units-thereof-i-s a forwardly and backwardly movable slide plate' 19 which has a tongue-and groove connecv tion withthe table member orthe separate units thereofaasshown at 2O in Fig. 1 of Y.the drawing. Substantially centrally of said plate is a standard 21 which is connected withrthe bottom: of another forwardly and backwardly movable slide plate 22 mounted vupon'V the ktop table member-15 or the sepalili in threaded engagement therewith, said shaft having a bearing at 25 atthel back of the frame of the machine, said bearing being to raise the plane 58 and the parts in connection with which said plane is mounted in the backward movement of the plane over a work-piece as hereinafter set forth.4 i

The slide plate 22 which is movable upon the top table member '15 is preferably provided with a wood facing`59 which is cut out at intervals to form three apertures 60 Vas clearly shown inFig. 2 of the drawing, vsaid apertures forming four forwardly and backwardly directed members 61. Pivoted to the opposite sides of three-of the members 61 as shown at 62 are forwardly directed ngers 63, the free ends of which'are pointed as shown `at 64 to engage-the inner edge of a suitable workpiece 65 'placed on the top of the slide 22, said workpiece being shown in full lines in Fig. 4 of the drawing, Yokeshaped members 66 are pivoted to the separate pairs of lingers 63 at the'opposite sides of the members 61 and extend beneath said members as clearly shown in Fig. ofthe drawing, and bolts or screws 67 are passed through the crossheads of said yokes, and

suitable lock nuts 68 are vmounted on the bolts or screws for retaining the yokes in predetermined positions of adjustment. Normally the fingers 68 or the separate pairs thereof are in a depressed and inoperative position and theyv may be raised into the position shownin'Figs. 4 and 5 by properly all adjusting ent.

The slide 22 is provided with projecting plates 69 located at the front portionof the apertures 60 and these plates form a straight edge against which lthe workpiece may be placed as shown in Fig. 4 of the drawing, that is to say, a workpiece which extends longitudinally of the 'front portion of the machine or a workpiece which isto be fashioned to vreproduce a molding or Vother strip, as is illustrated in Fig. 9 of the drawing.

I also mount and cou'ntersink in the wood facing 59 of the slide 22 at the fronto'f the the lock nuts 68, as will beapparvmachine a plurality of spaced clamp rods 70. the outer ends of which are hook-shaped inform and pointed as shownat7l to engage the inner edge of a workpiecel and the inner ends thereof are provided with winged nuts 72, which serve to move the' hooked ends thereof into operative land inoperative positions and it will be apparent that the hooked ends of said rods are free to move through apertures 73 in the facing59.

In the use of ,my improved machiney in dado work, I preferably provide one end of 4the slide 22 with an upstanding square edgev 74 shown in Figs. 1, 2 and 3 of the drawing, vagainst which a suitablev workpiece 75indicated in dot and dash lines inFigs. 2and 3 may be placed, and in holding said workpiece in position I employ a bar 76 indicated in full and dotted lines in' Fig. 2 of the drawing, and shown in full lines in Fig.

3 of the drawing, said rodbeing pivoted as shown at 77 to an arm 78 pivoted to thev slide 22 as indicated at 79. Another similar arm 80 is pivoted to the slide 22 as shown: at 81 and mounted in connection with the free end thereof is a vertical shaft-82 on which is mounted a coil spring 83 andthe upper gend lof the shaft 82 is threaded to receivean adjusting nut 84. The free end -of the bar 76 is cut out to engage the shaft. 82 beneath the nut 84 and the bar 6 servesto hold the workpiece'` 75 firmly in Vposition upon the slide 22 in the operation of cutting grooves transversel of said workpieceasn indicated at75EL in ig. 3 .of the drawingfin what is known as dado work. 85 may1 be mounted on the bar 76 and adjustable thereon to bear upon or to operate upon the top face ofthe workpiece and-two lof `these sleeves or bushings are indicated in-full and dotted lines in Fig. 2 ofthe drawing. f f

`The operation of my improved machine will be readilyunderstood from the :foregoing description when taken in connection with the `accompanying drawings IandQfollowing statement. When usin the machine Sleeves kor bushings Y for reproducing moldings anc other wood l strips of` a predetermined.contour, the .patterns or models of the strip to be reproduced are first placed in the holders 37 and adjusted'to proper:positions therein and secured in such positions by. the movable jaw' members 39. after which aworkpiecesuch as 65 is mounted'uponfthe front endrportion-of the slide 22 and extends longitudinally of the frame, said workpiece being heldin position by the fingers .63 and rodsf70 as will be apparent. The fingers 43 in vthe heads 42 are then placed uponthehighest points of the patterns or molds, the'plane adapteror mounting is placed on the bar "52 anda 'suitable plane mounted in connection therewith,

and said 'plane by'meansoffthe screws 46v is adapter 54 forwardly `and backwardlyiover the bar 52 and in each forward'and backward movement, the shaft 24 is rotated1 by hand one or more times, which operation will move the slides 19 and 22 forwardlycr b'ackwardly a slight extent. vThe above operation is repeated,and as the work proceeds the workpiece will be graduallyicu't and fashioned to correspond to the contour of yfthe; V'patternsior; models (supported fon-:the
