IMPRVEMENT IN APPARATUS FOR SHAPING- EARTHENWARE.

Theschedule referred to in these Letters Patent anc making part of the-same.

To all whom it lmag] concern Be it known that I, JOSEPH H. BADDELEY, of Greensborough, in the'county of' Greene, and StateV of' Pennsylvania, have invented anew and improved Apparatus for Shaping Earthen Jars; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being had wherein the clay is moulded to the required exterior 4 H form, and in the employment therewith of. a tool, adapted to shape the interior of the jar, and to f'orm the chime for the cover.

Also, in au arrangement of' the support of the said tool, for holding it while turning, and for removing' it from the finished jar, for the removal of the latter from the lathe, all as hereinafter' more fully specified.

The drawingrepresents a sectional elevatioirof' my impro-ved apparatus.

I place a plaster of' Paris moulding-jar, A, on the table B of' the lathe, and place the clay vtherein for the jar to he formed; and by the use of the tool-G,

Qsuspended from above so as to ,be gradually pressed down in the mould, to act upon the clay as the lathe is revolved, I shape the said clay within the jar up against the sides thereof, the said tool G being arranged at the distance from the inner wall of' the mould for the thickness of the wall of the jar to be formed.

'.lhis tool C is provided with a cleft, D, to shape the chime, near the top, for the support of the cover, and it is provided with a scraper, E, projecting over the topot' the mould, to remove any surplus metal.

The said tool is suspended from a bar, l?, hinged to thestandard G, which is jointed at the bottom, and free to swing toward or from the mould.

t The other end of the bar F'passes through a slotted support, and is notched at the under. side, Where it passes through the said slot, the vertical wallof the notch being atthe side of the post opposite' to the mould, 'and the inclinedwallon the same side with the mould. A

This notch limits the movements of the post Gr away from the mould, and causes the bar and the tool, thereon to lie-properly guided wheupressed downupon the clay, and to rise for disengaging the chime, when it is drawn through the slot from the mould.

I represents a holding-paavl,l provided with a han` dle, and arranged to bear against the post G,'pressiug it and the bar F in the direction' to hold the tool Qup to its work, and the notch in the bar against thepo'st rIhe parts are arranged in this position when the work is conn'ncnced, and so maintained during'theoperation; but when the work is finished, the pawl I is turned up, the bar E drawn back, and the tool O raised up and away from the work so as to disengage the cleft from the lip or chime formed by it, without breaking or disturbing it, and then the bar is swung over on the joint with the post G, and the tool C thereby removed from the finished jar.

I am aware that tools for a similar purpose with 'mine have been operatedby a lever, pivoted to `a swinging or vibrating post, and I do not claim them, except in combination, as hereafter specified.

Having thus described my invention, I claim as new,.and desire to secure by Letters Pat ent- 1.- lhe combination, with a moulding-jar, of a scraper, E, and clefted tool C D, al1 as shown and'described. i

2. 'lhe clefted tool C, in combination witlrnotched bar F, oscillating post G, dog I, and slotted-post Gr, all arranged as set forth. JOSEPH H. BADDELEY.
