Specification of Letters PatentNo. 26,647; `dated Januar'ywl, fi
To all lwhom it may concern: y n.
Be it known that I, THOMAS H. BURLEY, of the city, county, and State of NewYork,
have invented a new and Improved `Ma-V chine for Cutting Dovetails; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part vof this specification, in which- Figure l, is a plan or top view of my invention. Fig. 2, is a side sectional `view of the same. Fig. 3, is a horizontal section of the framing of the same showing a plan of the feeding device. Fig. 4, is an end view of the same. Fig. 5, is a perspective view `of the dove tail joint formed by my invention the joint being disconnected.
Similar letters of reference indicate` corresponding parts in the several figures.` a
The object of this invention is to obtain a machine for cutting dovetails `suchas eX- tend entirely through the work and are used for securing together the sides of boxes and similar purposes. a
i The invention consists in the employment or use of rotary cutters arranged with movable beds o n which the work is placed, substantially as hereinafter described, whereby the dovetails may be rapidly and perfectly formed and applied to cheap work, such as common boxes, which .could not hitherto be done on account of the expense of forming the dove tails.
To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.
A, represents a rectangular frame which may be constructed in any proper way to support the working parts of the machine. On the upper part of this frame A, two parallel shafts B, C, are placed, said shafts running in suitable bearings a. T o one shaft B, a series of arms b, are attached radially or at right angles. These arms are` of equal length and project from the shaft at opposite points in two rows, as shown plainly in Fig. l. To the end of each arm a cutter c, is attached obliquely. These cutters are of chisel form and are connected to the arms by set screws CZ, which pass through slots in the cutters and admit of the adjustment of the same to compensate for wear. The position of the cutters relatively with their arms b, is plainly shown inFig. 2.
In the frame A, and at the outer side of the shaft B, there is placed a vertical frame `D. This frame D.hasal"fucaiffacig@a each side of it and onlthe` topuofframeiDf a tilting bed E, is placedmsaid bedfbeing fitted on y centers .77,1 the "louter `one .being shown in Fig. 4. `In `consequence.ofxhaving` thebedfE, fitted on` thecenters f, f, itniay` be inclined in either direction, as shownfn` black and red in Figli, F11and securedzin either position by a,catch,fg,` ,The front edge of the bed E, is recessed asshown at Iz, Fig.` 1, in order to allow. the cutters to, pass,` through and"` perrnit the bed.' 1thoroughly i support the..worl wliilebeing actedgonlfby z the cutters. Intoeach rack e,`,e,of theframe D, a pinionz', gears].gThesegpinionsfare `placed on a shaftpifffonwliichfarealso placed two toothed wheels j, la, oneof which` j, is` considerablylargertthanthe other 1, 1as shown plainly Fig., Into.thelarge` wheel j, a pinionfhgears, pinionbeing` on a sleeve m, whicliiisplacedzlooselyvon al l shaft G. .On thisfshaft there isa similar sleeve n, with apinion o,` onyit,` the p inlono, 5
inner end of the sleeve n, aconical `heady?,`
the shaft by afeatherandgrooven. This sleeve s, has a sockett, at one end anda conical head u, atthe other, and byuadjust-J ing this sleeve s, either sleeve m, or '11 may be connected and made `to turn with the shaft G, as desired. i
To the shaft C, radial plates a', are at-` tached at two opposite points. Theseplates .l have each arms b', at their outer edgesand i to each arm br, a c utter c', is attached. p The a cutters c', are recisely similar to thecutters i,
c, or shaft B, uttheyha-ve a `different posii tion relatively with their shaft, the `cutters c', being placed in oblique planes as shown clearly in Fig. 2, said position being `dueI to the taper form oftheplates a.'
On the frame A, andat the outer side a the shaft C, a bed H, isplaced. This `,bed 1` i has racks cl', attached to its under surface,
one at each side, and into these racks pinions e', e', on a shaft I, gears. The inner edge* of the bed H, is notched :or recessed asshown f f at f', to allow the` cutters c to pass through while acting `on the work. y. The inner edge of the bed H, is oblique andparallel `with the planes in which the rows of cuttersfc, are
being connected by a; train ofwheelsp,with` .805
thesmaller wheel c,onfshaft To the,
placed. The outer part of the bed H, is attached to the racks eZ', by pivots g', and through the inner part of the bed H, set screws h', pass, in order to adjust the position of the bed as circumstances may require. On each bed E, a clamp bar J, is placed, said bars resting on springs and having their ,ends fitted in guides o', on which nuts j', are fitted.
The operation of the machine is as follows :-In order to cut the pins Zt of the dovetail the board Z, is secured on the bed F, by its clamp bar J, the inner edge of said board being flush with the inner edge of the bed E. VThe frame D, isY lowered tothe extent of its downward movement and motion is given the shaft G, by any convenient power. The operator by actuating a lever m, and shifting the sleeve s, connects the sleeve m, with the shaft Gr, and the pinion Z,
rotates the shaft F, through the medium of the wheel The pinions z', z', in consequence of gearing into the racks e, e, of the frame D, elevate said frame and bed E, and the latter is inclined so that the cutters c, as they rotate and the board Z, rises will cut the inner, edge of the board Z, and form rectangular recesses with obliquesides, fthe Obliquity of the sides being due to the incli* nation of the bed. When the recesses are cut, the operator by shifting the sleeve s, connects the other sleeve n, and consequently the pinion 0, with the shaft Gr, and the frame D, and bed E, are fed downward and when fully depressed, the sleeve s, is again shifted so as to connect the pinion Z, with shaft Gr. The operator then shlfts the position of' the bed E, so that it will be inclined in an opposite position and as the bed E, ascends the sides of the recesses in the board Z,
acted on by the cutters will be cut in an opposite oblique position with the sides first cut and the pins k, will be formed as shown clearly in Fig. 5.
In order to cut the recesses ax, of the dovetail that receive the pins Zc, the board bx, is secured on the bed H, in an oblique position which is determined by guides c", see Fig. l. The inner edge of the board ZJ", is adjusted flush with the inner edge of the bed H, and the bed H, as the cutters c rotate is fed by turning shaft I, toward said cutters which will cut recesses in the inner edge of board bx, said recesses having parallel sides.V When' the first cut is made the bed H, is moved back, the board X, invented on bed H, and a succeeding cut made. By this arrangement the recesses are made in dovetail form as shown at (ZX, Fig. 5, to receive the pins 7c.
rlhis machine performs its Work rapidlyand well and all dovetailing which extends entirely through the Work, such as dovetailing for boxes, etc., may be done at a small expense.
I do not claim the rotary cutters c, in connection with the horizontally moving bed H, for they or their equivalents have been used; but,
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,
The employment or use of the rotary cutters 0, in connection with the rising and falling tilting bed E, arranged substantially as and for the purpose set forth.
THOMAS H. BURLEY.
