'To ALL WHOMLIT MA-Y' coNoaRN; n i Be it known that we, WILLIAM H. DoANn, Gnamrr. V. OaroN, `and WILLIAM E. LONDON, of Cimzinnati,v

l ,Haniilton county, State of Ohio, have invented a new and improved AUpri'glitfrSlfulping, Co'rnering, and Mould- -ihg Machine.;4 and we do hereby declare that the following is a full, clear, ander-act description thereof, reference being' had to the accompanying drawings, making a part'of.thisnspecication, in whinh.-

l*lignre v1 is a front elevation of themachine, complete.

Figure Zisa transverse section taken in a vertical plane throughthe centrelpi' .this machine. y Figures 3 and 4 are views of themovable cutterhend, appliedtoy the upper end-of'the.spindle.

,Figure 5 is a cross-section through the cutter-head; yigurcs 6 and? are enlarged views showing the movable supportfor the guard-cage. '5`"5Similar letters of reference indicate corresponding parts inthe several figures.

First, lina' cutter-head'formed in two parts independent ofthe fguid'collars g,'s' *iasy to receive bits of various lengths, 'and with a rectangular eirtension to support the cutters and break-irons; secondly, in the use i of adjustable break-irons in'conjunction -with moulding-cutters, whichfarehc'liihped and held in place upon a stud between movable collarsfor the purpose of preventing theslivering 4the stuiv while cutting, and also for regulating lthe depth of cut, as will be hereinafterv` described ;t hirdly, iii providin'gi,for supportingla vertically adjustable shield or guard upon the surface of the table, and near thoputters, lin such manner that this Y"shieldshall n ot be in the'way of' the stu' during the action of the cutterspaiiid in' such manner as to dispense `-with theuse of alframe overhanging for supporting such shield, asfwill behereinafter described..

ATo enable others skilled in' theart to understand our invention, we -vwill jgdescribe its'construction andl 4o eration.

y p The table consists oil a horizontal top A, upon which the stu' is place to-b'e cut, anda `frame, B, which supports saidtop and also the cutter-spindle. The spindle'G is supported'atlits'l'ower conicalend upon a step, a, and near its upper end by means of a journal-box, Zz, which latter is secured rigidly to the frame or stand B. The

- step a is constructed with al male screw-thread upon it for receiving theIw'heels'ID and E," the hubs of which beur p against theends ot' a box, c, through which the screw-step a is allowed to in ove up and down loosely. The handwheel D, which rests upon the top of the box c, -is used for raisingorlowering the step and its spindle,'and the hand-wheel E is used for securing the step and the wheel D rigidly in place after adjustment. The keyltenon "ci, which .projects from the box c, and enters a vertical groove yin thescrew-step a, as-shou'n in iig. 2, prevents the step from turning with the wheelD. The wheel E serves as a kind of jam-nut for the step and upper wheel, and holds these parts so tight that-the rotation'of 'the spindle and ,jarring-lof *the machine will not allow wheel D to become loose. Betweenthe step a and upper bearing b a belt-drum, F, is secured to the spindle C,

- by i'ineans of .which motion is communicated to the latter from 'any convenient motor. The upper end of the spindle C has a screw-hole madecentrally in it for receiving a male-screwz,"d, whichis forled on the low'er end of the stud g. This allows-of. the use of -studs or cutters of di'erent lengths and kinds upon a single spindle,

and obviates thel necessity of 'relnoving the spindle when a cutter-head' is to be changed. The stud g is constructed with a cylindrical collar or flange, g', upon it, which forms the gauge against which the stuii' is held during the cutting operation. Onthe upper end of.,the stud g'a screw-thread is cut-'for'receiving a nut, g. Between this nut g2 and the gauge-collar g1, two loose collars h la, constituting an independent',v cutter-head, "formedin two parts, and two cutters 7c k, are confined, as shown in i'igs. '3 and 4. These two halves, h, are made alike, and have each a rectangular extension, k', for lateral support of the cutters, and also two grooves, t'z', into which the ends ofthe cutter-blades 7c 7c iit. These grooves are madesli'ghtly taperin g so as to cause the tapering or slightly bevelled ends of the blades c to fit snugly in their places'when the nut g2 is tightly tied up. Each blade k has a break-iron, 7c', secured to its inner side by means of screwsl]` which pass through oblong slots made through` the blade k, and enter the break-iron. Thlese caps or break-irons are also supported by being firmly clamped aga-inst the rectangular extensions h. Thus the latter can be adjusted and set as may be required.

These ,break-irons have those edges nearest the cutting-edges of blades 7c' clb'e'velled so as to forni double heels, therefore, for breaking the chips and'preventing slivering or tearing of the wood. The rectangular Vmoved around the axis of the cutter-head, and alsoV adjusted vertically, substantially 'as extensions I/of the collars h'serve as side bearings for thaeutters,and prevent lateral vibration thereof. The cuttcrs'lc c can be readily removed by unscrewing4 the nut giand slipping off tlleuppcr collar It, and cutters' of diiferent siaes introduced in their places.V By having both collars 7th removable,'others'otl different sizes' can be usecl intheirV stead without the necessity of changing the stud which receives said collars. .Anopen-v Work shield, G, is arrangedover the cutters to prevent'injury to the hands of the Workmen. This shield is con neetedby means of asleeve and set-screw to a post, m, and Vmay be raised and lowered and secured at any desired height above the surface of the table-top, t The post m issccured to a horizontal bracketym", whiclris formed on a flanged ring, y), that is-let into the annular recess which is formed in the table-top A, concentric toV .the axis ofthe spindle C. "lIhis ring p is held down in place by means o'ifanother ring, r, which is. also recessed into. the table-top, as shown in figs. 2 and 7. 1 Thenpper surfaces of both rings are Hush ivith the surface of theY tabletop, so as not to bein the way of the stui' which is presented to thc cut' is. The inner ends of the raised bracket mare rounded, as shown in fig. (i,` and constitute abutments against which the stuE-impinges, so

4that said bracket, with its ring p; will be niovedraroulnd in advance of the stuff, and will consequently not be in the way. ly this arrangement a safety-shield caribe supported upon the table-top Without the employment of an auxiliary frame. As hitherto, the shield will always be arranged conecntri'ca-lly over the cutter-stud, and will protect the hands of the operator fromcoirtact' with the rotary cutters, 'The machines are constructed with a single spindle, or with two spindles to rotate in opposite directions, to'suit the lnature; of the work to be perf formed'. l 1 t A Having thus described ourinventiori, what we claim as new, and desire to .secure by Letters Patent, is- 1. The combination of the adjustable break-irons t c with the cutters k 7c, and the removable collars L h, all constructed and arranged in the manner and for the purpose desribed.

2. The application of the shield G- to a post, m, which is allowedto revolve around the cutter-head, substantially as described. y y A i i 3. Sustaining the safetyshield Gr upon the table-top A,` by'means which will adinit of said shield being described. y
