Be it known that we, FRANK- B. Manny and Jessie D. Wane, both citizens of the United States, and both residing-at Savannah, in the county of Ghatham, State of G?1igia, have invented certain new and usefu I mprovements in Turning and Fluting Machines, of which the following is a specification. I a v This invention relates particularly to a machine of thegeneral type disclosed in our prior Patent No. 1,175,969, March 21, 1916, or turning. columns or posts of wood, from rough material to give them a round, tapered, or gther desired form. 4

' This inventi'on'has for its object the provision of a machine o'fthis general type capable of producing grooves, flutes, or ribs on round-or tapered columns or the like of various diameters as'desired-for purposes of ornamentation.

Theinvention has further for its object- 1 the provision of a slidin frame carrying a cutter for formin peripieral beads on the column, caps, or ases, which frame is adjustable into and out of operative position so as not to interfere with the operation of the fluting or grooving mechanism.

Another object of the invention resides in the provision of a carrier for the cutter carriage which is adjustable toward and away from the machine so ;as to accommodate work of various diameters, together with a templet cooperating with said carrier in anyadjusted sition.

" A still rther object; of this invention is to provide means for/automatically and 'manually controlling the operation of the machine so that accupwy and simplicity These objecjstd'gether with attendantad- "vantages will be a parent as the invention becomes better .un erstood by reference to the accompanying specification and draw ings forming a part thereof, throughout the views of which like-characters of ref .erence have beenused to designate like parts.

Referrin nor more particularly to the draw ngs t e lathe bed 1 may be of any suitable constru ction, andis supported on legs 2 placed at suitable intervals throughout the length )f the lathe bed. Mounted on the opposite ands of the lathe bed are the head stock 4 ani the tail stock 5, the latter of which may be constructed in any usual 'or well known -manne 'r. The head stock preferably com; rises a shaft 6 having a fast p ulley 7 and a hose pulley B'carried thereby.

or the pur e of providing a relatively slow drive or the work, a supplemental drive pulley 9 n .ay' be provided on the shaft "-10 extending a; right angles to the main shaft of the head stock and carrying a worm 11 meshing witl. the worm wheel 12 mount-.

ed onthe end oi the head stock shaft. This reduction mech tnism may be thrown into and out of 0 e1 *ative pos tion by means of the lever'13 pivoted to the; headstock in any desired manner at one end and having a spring lock 14 lor holdin' the worm in osition. A spring contiQl ed clutch mem er 3 'slidabl secured by a 'pin and slot connection to t e shaft may be em 'loyed' too eratively 'cou le'the .worm whee -12 to thes aft,

Secure 'in'an v desired manner to the rear .of thelathebed there is provided a shelf 15- havingsuitablel iraceslficoiiperatin'g with the supporting-1e of the lathe bed. Mounted on the shelf 5 in a hollow carrier 17 for the lathe carriag {e which hasmounted thereon the turning a rid fiuti mechanisms. The

I turning mechanism pre erably comprises a rotary cutter 18 mounted on the shaft 19 carrying a drivepulley 20 adjacent one end. The shaft 19 is grooved lon tudinally at 21 and the cutter is connected ereto by keys 22 in such manner that the cutter while bein operatively driven by the shaft is free to s 1de longitudinally thereon throughout the length of the machine so as to operate upon the work from end to end. i

' The shaft 19. passes through posts 24 on the lathe carriage and is joumaled therein by m ans of the sleeve 25 formed integral with, or connectedin any desited manner to the hub 26 from which the cut is 18 radiate. Mounted on the sleeve 25 i mediate the length thereof, and preferab between the posts 24, is a friction drive pulley 27 with which the friction wheel 28 on the shaft 29 is adapted to mesh at certain times throughout the operation of the machine as will be hereinafter described. The friction wheel is secured to one end of the shaft 29 which on the'work throughout as much 0 length as desired, and that the flutlng cutis joumaled in the pivotally mounted bracket 80. Intermediate the ends of' the shaft 29 is mounted a fluting or grooving cutter 31. By reason of the pivotal mounting of the bracketviQ on one of the posts 24 it will be apparent that the fluting cutter may be brought forward into cutting position so as" toform ribs, grooves or flutes on the work depending on the construction of "thecutter blades, and then thrown backwardly into inoperative position. For moving the friction wheel 28 into en' gagement with the drive pulley 27 when the cutter is swung forwardly, we have shown a cam guide 32 carried by one of the posts 24 and cooperating with a suitablyformed lug or set screw 32' on the bracket 30. This construction makes the control of the fluting cutter automatic, and increases the safety factor of the machine by having idle parts at rest.

For moving the carriage longitudinally of the shaft, it is. provided with a depending lug 83 hiivjng an interiorly threaded openin formed. thereinadapted to cooperate wit the screw-drive shaft 34 driven through the medium ofulleys 35 in either direction. By reason of this screw feed 'it will be apparent thatthecar'riage may be moved longitudinally so that the rotary cutter ma act ter may also form a rib or groove for any length desired, thele h of the cut bein' automatically. controlle as will be. descri hereinafter. I

In order'that the machine may be used for cutting tapered columns or .Ithe like, there may be provided an angle" iron 36 mounted on the shelf 15 tothe rear of the carrier and-supportingatemplet'or attern 87. For' cooperation with the temp at, the

g -is provided with a rearwardly P the 1.11am v carriage-mrrier by means of levers 41. For

permitti movement of the carrier in accordanoe ith'the' design on the faceof the templet there may be provided a pivot 42 extendi --ind'hav1 a oose sleeve 44' thereon c0- operatin -with"'the sides of the carrier. .In '0 er that the machine may be used to operate upon-'columns or posts of relatively llrge diameters it is necessary that'nieans for moving the rotary cutter and the fluting cutter-to and from the work be provided. In the embodiment of our invention disclosed in thealrawings this means is shown as compris ng slots "45 formed in the upper surface of the shelff35-through-which the pivot 42 for the carrier and the eye-bolts 46 for the angle ron may pass and have relatively unrestrlcted lateral movement toward and from the lathe *bed. For accomplishing this lateral movement of the carrierand templet in unison there may be provided a lever 47 secured to, the rod 48 which is connected at suitable intervals vthrou hout ,the length of the machine to lugs 49 ormed on the base of the angle iron 36 through the medium of toggle links 50. The lever 47 is in turn connected with the carrier 17 by the link 51 havin pivotal connection at each end. From t e foregoing it will be apparent that when the lever 47 is moved toward or from the-o erator to accommodate the insertion of wor of different diameters,

that the carrier and the templet will be moved in unison in a corresponding direction. For locking the carrier in adjusted'po sition the pivot i's preferably screw threadthrough an opening in the carrier ed at its lower end -and;provided with a nut 'i eye pass and which is adapted tocooperthe .angle iron is free to move, but when the I bar is swung through the medium of the handle 59 that the I-circular face thereof engages th'e locking. plates, the angle iron is clamped in its adjusted As before h e lrotafl' cutter-18 p r es Pan th tapered column, and -the"fluting cutter s then swung intoiposi'tion to form ornament tions extending ongitudi'nally of the 1 as desired. If it is desired to form a column hav' a plurality of jlutes, this may be accomplished by holding the column stationary and moving the cutter 18 longitudinall thereover, the column then being turned su ficiently to permit the cutting ofanother flute at any desired angle to the flute or flutes already formed. In order that the carriage may be automatically controlled after it has traveled the desired length, we have shown van automatic belt shift comprising a tappet rod- 60 extending substantially the entirelength of the machine and supported on the carriage bythe upright 61 which has the a per end thereof turned atright angles to t e main body thereof as shown at 62 to a form a support for the bracket 39 when the same is swung to its rearward or inoperative position. Admstably mounted-on the rod 60 are stops fi lrwhich may be set at any desired position and which are operated by the upght 61 atithe desired limits of its travel to slide the tappet longitudinally. longitudinal movement of the tappet rod is utilized through the mediign of the belt shiftin member 65 to slide 'edrivin belts ffromt e pulleys onto the loo'se pu ey 66 sometimes to stop the operation -cftthe machine for in the desired order, or vice versal As it is desired to shift the belt manually various purposes, we have rovided a lev r 67 pivoted intermediate its ength to the ea rier 17 and having its opposite endconnect- I t ed through the medium of-the opera-tor.

This con- 'struction is found convenient when it is desired ito roughout a comparatively short ion of its length and when it is not dewe preferab form the fast ulley 7 with a plurality of eoncentri'c ann arly arranged perforations 76 adapted lac-receive a pin 77 M a spring lever 78 securedin anyconvenof a bolt andslot' a pulley Ylroduce ornamental efiects on the' In .of the cutters that t e I be successfully employed for metal or stone ient manner to t as lathe bed. By this con struction the work may be held in an desired position wiiile being ornaments and may be moved to the desired extent to properly s ace the )mamentations. In grder that t e fluting :utter .31 may cut a. groove I or bead longitudinally of the column and not spirally thereof, it is essential that the carrier duringth is operation be held against pivotal movemer t. A This is accomplished by providing a swim gi carrier and ads pte depression in the arm 80 secured to the an;

latch 79 secured to the p to engage a notch or gle iron .carryirg the te'mplet, This' coni struction render; the move the carrier so taste cause thesame'ito follow the contc ur of the templet.

After the calm has been turned to the I desired shape an lspi tably ornamented, there may be formed thereon'a peripheral head by means of the be tding cutter SI-mounted on the shaft 82 suit ibly ournaled on the frame 84 slidin in the gropv edguides 85 on the lathe bed low theiifiperrface thereof: The frame is slid ve rti y-i'nthe guides 85 by means of the handle 86 attached to the 'counter-baIa-nceL lever 871by-theshaft 88,

For driving the beading cutter there may be em loyed a jack shaft-90 driven by the pulley 1 and transmittin 'motion to'the cutter by the driver 92 an the belt 94, said belt pass" around 95 or the shaft 82 an thence around the idler pulleys 96, one of which may be. yieldingly held'iu' position by' the' spring 97; The. rran such that ,whenj ilhe ame is slid downwardlyinto inoperative position the belt passes loosely around the pulley. 95 so that the heading out er is not driven at this time.

weight 40 inefiecti veto ment of vpulleys is.

As soon, howev| :r, as the frame islifted into operative position the, belt is automatically tightened due to thearrangementvof the pulleys and the cutter is rotated to form a ead of desired formation o'n the column or 0th piece of v ork carried by the lathe.

T$is-jmmhim may also be used fer-formingbase -or capital members by attaching a face plate of any well known construction to the head stoc k, in place of the center, and

then securing the base or capital members thereto. When so attached they may be operated u ter and in the desired manner.
