POTTERY-SPINNING WHEEL.

State of Ohio, have invented a certain new 'and useful Improvement in Pottery-Spinning IVheels, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a side elevation o f a spinning wheel embodying my invention; F ig. 2 a vertical section on the line 2-2 of Fig. 1; Fig. 3 ahorizontal section on the line 3-3 of Fig. 2,

and Fig. 4 is a detail view in side elevation of v designates a suitable frame having bearingsfor a vertical shaft 2 that at its upiper end cari-ies a spinning wheel 3, the sha t being provided with a fast pulley 4 and a loose pulley 5 for alternate engagement by a belt 6 receiving motion fromY a suitable source.

The shaft 2 is hollow or tubular, and vertically movable Within it is a n'icld-lifting rod 7, which at its upper end has a head or cap 8 to engage the bottom of a mold 9 in the spinning wheel. Also mounted in bearings in the frame 1 is a rotatable and vertically reciprocable rod or shaft 10 which, at its upper lend, supports and carries a disk plate 11,

having in its edge a series-as shown four' of semi-circular notches 12, each adapted to receive and support a mold, for which purpose the mold is provided at its top with an annular fiange formed by an annular groove 13 just below the to of the mold in a rim. or fiange on the in oll t iat rests upon the upper edge of the spinning wheel, the mold being placed in and removed from engagement with the plate or disk-notch by a horizontal movement. of the mold. The rotation of the mold-su porting plate or disk is for the purpose of 4lbringing the molds carried thereby successively into position in and out of alinement withthe spinning wheel, and its vertical Specification of Letters Patent.

` mold into the spinning wheel, and.4 then lifting it therefrom, these movements taking place in succession for the placing of a vessel to be operated upon n1 the spinning wheel and removing it therefrom, and all thesein c-vements are produced automatically, as will be hereinafter more fully described.

UNITED saires- PATENT ermee. l

The rib or former 14 which has an edffe corresponding to the interior surface to liev formed 'on the vessel is carried by an arm 15, to which it is removably attached, so that ribs of different configuration may be einployed, said arm being pivoted to a. vertically reciprocable-rod 16, so that the rib has a compound movement consisting of a vertical movement lto project it into the vessel within the mold, and cause it to engage and operate on the interior surface thereof, and to lift the rib out of the mold, and of a swinging movement to carry it to one side of the vessel in the mold when it has been removed therefrom, so that it will not hinder the lifting of the mold with the vessel therein from the spinning wheel, and to bring it again into position for action upon the vessel in the mold. To impart this compound motion to the rib, its carrying arm at its pivoted end has attached to it a pinion 17, which on one side meshes with a stationary rack .lfastened to the frame 1, and on its op osite side meshes with a similar rack carriedl by a pit-man 19, whose lower end is pivoted. to a crank pin on a worin wheel 20, so that by the revolution of the latter the pitman is reciprocated and its rack, meshing with the pinion, revolves the latter, thus imparting the swinging motion to the rib, and the vertical motion being produced by the action of the pinion upon the Vstationary rack 18. Contiguous to the ath of the rib or former, just before it com etes its movement away from the vessel in t e mold, is a plate or blade 21 conveniently made of sheet-metal sup orted by an arm 22 from the frame I, an having an edge which Will engage and clear or scrape from the rib or former any clay which may adhere thereto. To automatically shift the belt 6 from one pulley to the other, I attach to the verticall reciprocating rod-16 a belt shipper 23, whic when the rib or former descends into the vessel in the mold, shifts the belt into engagement with the fast pulley to cause the when the rib or former is lifted from the vesmovement is for the purposecf lowering a sel inthe mold, shifts the belt to the loose 4110 'spinning wheel.

G connected to pulley to stop the revolutionofthe spinning whee so that the rotation ofthe spinning Wheel is automatically controlled.

The lifting of the\meld=carrying -late or disk 11 is automatically accomplis ed uby means of an arm 24 attached to and projecting at right-angles from the pitmanli) and a disk or wheel 25 on tlie rod or shaft 10 which l supports said plate 'or disk, said arm being Amold-carrying disk or plate, moves horizon- Atally into engagement with a ratchet tooth and thereby rotates the wheel and its shaft. On the descent of the arm 24, the mold-carryino' disk or plate descends automatically by the action of gravity and places a mold with a new vessel to be operated on in the Simultaneously with the rising and falling of the mold-carrying plate or disk, the mold-lifter is raised to lift the mold containing the finished vessel from the spinning wheel and descends back into the` spinning wheel, the raising of the lifter being accom lished by means of an arm 27 attache to the vertically reciprocating rod 16 in such 'a position as to engage the lower end 'of the lifter-rod 7 when the vertically reciprocating rod 16 is raised, and the lifter descending by gravity as the arm 27 descends when its carrying-rod 16 moves downward. I also mountupon the vertically movable rod 16 a horizontal arm 28, which extends in position to have contact with the bottom of the spinning wheel to act as .a stop or brake to arrest the revolution thereof. by the time the belt is shifted from the fast to the loose ulley, thus avoiding the inco"venience W iich would result from the continued revolution of the spinning wheel and mold, due to their momentum.

vWater or other liquid, such as coal oil, should be supplied to the vessel being molded, and I provide means for automatically delivering water to the interior surface of the vessel being operated on. Such means may have various forms. Thus I may provide a tank or receptacle 29 located sufficiently above the spinning wheel so that the liquid will ass therefrom through a tube or 'pipe 30 w ose discharge end is at the roper point for the deliverv of the liquid to tile vessel being molded, the water orother liquid being supplied to the vessel by a pump 31 that is autoinaticaly operated by its' piston being the belt-shipper 23f .A pipe or' tube 32 runs from the umplto the tank or receptacle. .I preferab y mount the tank or receptacle on the rib-carryin' arm 15, so that the discharge of water may be controlled by the movements of said arm. arm is lowered or moved into )osition for operating on the vessel in the mo d, the pipe 30 will be placed in' such' osition that water iwill constantly flow or drip from the tank 30 into said'vessel, while when said arm is lifted to taks: the. 'rib out of .the vessel iii the mold, the pipe 3() will be lifted to .cause the stoppage of thcilow of water. I also mount on the arm 15 a tool to scrape orclean the upper edge of the mold, 'which consists of a shank 8'0 33 adjustably attached to the arm 15, and carrying a knife or blade 34 at its end to engage any clay. adhering to the mold and scra e it olf, when the arm 15 is in position to I a so may provide for delivering a jet of water to the rib or former after each operation of the blade 21 on it, to Wash it.

The operation of my s inning wheel is as followsz-With the mol carrying disk or 90 plate in an elevated iositon, moldswith the vessels to be form therein are placed, one

at a time, in the notches or recesses in the -A plate or disk, and the latter, with the mold,

directly above the spinning wheel,' descends, 95

carrying such mold into the spinning wheel, the pitman 19 descendin at t e same time, and throuvh the rack an pinion mechanism described tbringing the rib or former downward into the vessel, and also moving downward the bar which carries the belt-shipper 23, so that by the time the rib or former ias reached its operating position, the belt will be shifted from the oose to the fast pulley,

and the revolution of the spinning wheel with the contained mold will take place at a rapid rate of speed. The rib oi' former having operated on the vessel being made for the desired length of time, which is determined by the rat-e of revolution of the worin wheel '119 20, the pitnan will, by its upward movement through-the rack and pinion mechanism, lift the rib or former out of the vessel and swine it to one side, and at the same time, the lbelt shifter will move the belt from the tight to the loose pulley, and the moldcarrying disk or plate will be lift-ed to lift the mold containing the newly formed vesselA out of the spinning wheel, bein@r supplemented by the mold lifter 7, and the lifting 12g,

of the mold from the s inning wheel being accomplished, the mol carrying disk-or plate will be revolved a quarter of a turn to remove the mold with the newly-formed vessel from over the spinning wheel, and to "1,25 bring the next mold with a vessel tobe operv ated on into position over the Spinnin wheel, ready to be lowered therein. It n be observed that all the operations are automatically performed, excepting the mount- 13;]
