The present invention has relation to a press for manufacturing earthenware covers for teapots and the like,and has for its object primarily to provide-for the more economical and expeditious manufactureof the article from clay dust or plastic clayiby the present pressing operation than was heretofore the case.

In order that this invention maybe clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of drawings, upon which 5 Figure 1 is an elevational viewofia press ing machine for manufacturing an earthenware cover fora teapot or the like, con structed according to the presentinvention.

Figure 2 is a sectional plan view of the pressing machine shown in Figure 1. 1

Figure 3 is a sectional elevation illustrating the dies in engagement, having completed the manufacture of the cover inone stroke.

Figure 4 is aplan viewpf the femaledie in the open position, to permitof theremoval oithe cover. 5 v t Figure 5 is a sectional elevation of the female die inthe open position, the cover being elevated ready for removal.

Referring to the drawings, the machine comprises a bed a whereon xtwo uprights or verticalcolumns a aremounted terminating at their upper extremity in astationary cross head (i A cross beta-m tt is-fixed across theuprights or columns, anda. main vertical screw 5 is adapted tooperate-in a tapped bush or aperturelinlthe cross-head a and is provided atits lower partvwitha member 72 adapted toslidably operate but not rotatein thecrossbeam a whichimemher at its lower part carries the male die 0 hereinafter more particularly referred to. The vertical screw 5 has arotary or swivel connection with the slidable member-$ and at its upper part carries a handle 6 in well known manner, which may be provided with any suitable retentive means, If. Mounted upon each of the upriglitsor columns ta is a cam device :61, having ineach'instance anarm d (see particularly iFigures Qand 4), the two arms being united by a connecting rod d incorporating a turnbuckle d or like adjusting device. One of the cam devices d carries an operating handle d. The female diecomprisesa base 6 whereontwo carrier members e are Slidablymounted.

These,carrier members are normally urged apart by means of compression springs e mounted on spindles 6 Each spindle e is attached toione carrier member adapted to slide in1relation to the complementary carrrerkmember. A one-piece annular female die element flsee particularly Figures3, 4 and5) is letinto a cavity in a stationary part eFofrthe base 6, so as to be readily detachable j therei'rom and interchangeable. Associated with each carrier member 6 are upper and lower diesections g and it respectively, adapted to operate aboveand below the one-piece annular female die elementlF. kThe upper die sections 9 are of semi-annular formation, and are located by means: offlanges bolted to the carriermemhere 6 (as illustrated). ()n their underside, they are recessed-to constitute an annular channely (seeparticularly Figure 5), with the upper part of the female die element f. The lower die sections hihavetheir extremities recessed and rounded (see particularly 1? igures 2 and 4) and are secured to the carrier members e -by vertical pins 6 whereon rollers e may be incorporated. Centrally iwithin tlre base 6 an aperture is provided, lwhereina central GOIlCfiLVltOllS die 21 is adapted to slide upon or in relation to a fixed rod normally protruding above the said die This central die 2' is adapted to be elevated :by suitable foot :mechanism 6 i" igure 1), :when the lower die sections 7t togetheriwitlrthe upper ones g) havebeen displaced respectively away from one another-(Figures Land 5). It'will be appreciated fromuthe foregoing that the carrier members e are capable of being slid upon Kthebase e and carryin the upper and lower die sections' gland h t ierewith in reference :to 'the stationary element 7. slidingwdisplacement is effected by means of theltwocams d co-operating with the rollers dzagainst the actionio fthe compression springs 5?.

The malerdie c is ofboss-hke formation 9 The inward (as illustrated), and is centrally apertured to i receive the rod j.

in operation, two carrier membersc supporting upperandlower die: sections gand the space between male and female dies (see again Figure 3), that is to say, pass beneath the lower sections it on to the central die i to constitute the knob is) (Figures 3 and 5), extend over the face of the female die 7 to constitute the dome or top 10 of the cover, pass into the undercut part 9 of the upper die sections 9 and adjacent part of the female die 7', to constitute the locating flange and extend around the upper part of the male die to form the annular wall k. During this operation the knob is centrally perforated by means of the pin j. In order to remove the completed cover, the handle 1 d is manipulated, the springs e forcing the carrier members 6 with their respective die sections 9 and it apart, the foot member 1' then manipulated, causing the central die 1' to elevate the finished cover (Figure 5) whence it can be easily removed off the die by hand without fracture.

It will be appreciated that by simply changing the one piece annular female die f and male die element 0 and upper and lower die sections 9 and h, the shape and dimension of the lid can be altered to suit different requirements.

In a modification of the present invention, instead of employing a detachable one-piece female die element 7', same may be incorporated permanently in the base 6, and instead of having detachable upper die section 9, the carrier members 6 themselves may constitute these features by being undercut to form the locating flange 70 The lower die sections it and central die section 1' are provided as in the previous instance. In this modification it will be ap reciated that only the one shape and size of cover can be manufactured. In each instance, it will be understood that by employing a onepiece female die element f, the article when pressed has for its main part a plain outer and inner configuration. That is to say, there is no diametrical line giving the appearance that the cover has been made in two halves.

\Vhat I claim as my'invention and desire to secure by Letters Patent is 1. Apparatus for the manufacture of an earthenware cover for a teapot or container comprising in combination a male die, a female die consisting of a one-piece concavitous bod part, opposed pairs of relatively slidable upper and lower die sections associated with said female die, the lower sections being adapted to assistv in constituting the cover handle, and the upper sections assist in constituting the annular wall and lateral locating flange of the said cover, and means for slidingly displacing the opposed pairs of die sections for the removal of the cover.

2. Apparatus for the manufacture of an earthenware cover for a teapot or container comprising in combination a male die, a female die consisting of a base, a detachable concavitous one-piece body part interchangeably supported thereby, opposed carrier members relatively slidable on the base, upper and lower die sections associated with each carrier member, the upper and /or lower sections being readily interchangeable, a central die section on the said body part, upper and lower and central die sections being adapted to constitute the external configuration of the cover including the knob like handle, body part, locating flange and annular wall, and to permit of its with drawal. r

5. Apparatus for the manufacture of an earthenware cover for a teapot or container comprising in combination a male die, a female die consisting of a base, a detachable concavitous one-piece body part interchangeably supported thereby, opposed carrier members relatively slidable on the base, upper and lower die sections associated with each carrier member, the upper and/or low er sections being readily interchangeable, a central die section on the said body part adapted to slide vertically for ejection purposes, a stationary rod associated with the said central die section, upper and lower and central die sections being adapted to constitute the external configuration of the cover including the knob-like handle, body part, locating flange, and annular Wall, and to permit of its Withdrawal.

In witness whereof I have hereunto set my 20 hand.
