IMPROVEMENTS IN APPARATUS FOR SHAPING CLAY WARE
Year: 1884

page_text: I, FREDERIC GROSVENOR, of Eagle Pottery, Boden Street, Glasgow, in the
County of Lanark, Potter, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN APPARATUS FOR SHAPING CLAY WARE," to be as follows:-
My Invention relates to an improved arrangement of apparatus for shaping
articles of clay, in which the articles to be operated upon are held stationary while
the shaping tool or profile rotates and moulds or shapes the ware.
The apparatus is especially applicable for shaping such articles of hollow clay
ware as jelly cans or pots which are partially shaped in a jolly or other machine,
and afterwards transferred to and finished in a separate machine.
According to my Invention I fix on any suitable framing a strong stud or
spindle overhanging the end of the frame and upon the end of the stud I screw or
otherwise fix a block which serves to support the jar or other article to be shaped.
Between the carrying frame and the block I fit a loose belt pulley which rotates
upon the stud or spindle and on this pulley I joint or pivot a shaping tool or
profile whose shaping end is over the neck of the jar. A projecting end or tail
piece is formed on the shaping tool and this is acted on by a sliding cone, eccentric
or similar device fitted on the stud and brought into operation by a pedal and
crank, or by hand. When the tail piece is raised the profile or shaping end of
the tool is brought into contact with the article to be shaped, and a greater or
less degree of pressure being applied the tool acts to a greater or less extent on the
article.
The shaping end of the profile may be retracted by a spring on the completion of
the shaping operation.

page_text: I, FREDERIC GROSVENOR, of Eagle Pottery, Boden Street, Glasgow, in the
County of Lanark, Potter, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention relates to an improved arrangement of apparatus for shaping
articles of clay, in which the articles to be operated upon are held stationary while
the shaping tool or profile rotates and moulds or shapes the ware.
The apparatus is especially applicable for such articles of hollow clay ware as
jelly cans or pots which are partially shaped in a jolly or other machine and
afterwards transferred to and finished in a separate machine.
In the accompanying drawings which serve to illustrate my invention Figure 1
is an end elevation and Figure 2 is a sectional side elevation of a modification of
the improved shaping machine. Figures 3 and 4 are sectional views illustrating
modified arrangements of parts of the apparatus.
The improved apparatus comprises a framing, composed of standards A which
carry a strong stud or stationary spindle B overhanging the end or each end of the
frame; and upon the end of the stud or spindle B I screw or otherwise fix a
block C which serves to support the jar D or other article to be shaped. Between
the carrying frame A and each block CI fit a loose belt pulley E which rotates
upon the stud or stationary spindle B and is driven by a belt F from a pulley G
on a countershaft H and on the pulley E I joint or pivot a shaping tool or profile I
whose shaping end i is over the neck of the jar D. A projecting end or tail piece J
is formed on the shaping tool I and this is acted on by a sliding cone K or
eccentric or similar device fitted to slide on the stud or on the eye of the pulley E
and brought into operation by a hand lever L and forked lever or by hand.
When the tail piece J is raised by the cone K the profile i or shaping end of the
tool I is brought into contact with the jar D or other article to be shaped, and a
greater or less degree of pressure being applied the tool acts to a greater or less
extent on the article. An adjustable stop is provided to regulate the extent of
movement of the lever L. A longitudinal movement may also be imparted to the
shaping tool I (in cases where the article D is to be faced) by depressing a hand or
foot lever N whose arm N¹ fits in a collar on the eye e of the pulley E.
The shaping end of the profile may be directly retracted by a spring on the
completion of the shaping operation, or the hand lever L by which the cone K is
operated may be retracted by a spring L¹ as is indicated in the drawings.
The machine may be fitted. with a single block and operating tool and pulley or
it may have a block fitted at each end as shown in which case the parts. are merely
duplicated. The counter shaft is however fitted with two sets of fast and loose
pulleys and belt shifters g are provided for each set so that the one profile may
be driven while the other is out of action or both may be driven simultaneously.
A hinged bracket M may be provided to support the overhanging end of the block
with the jar D.
In lieu of pivotting the profile or tool I on the pulley E I may pivot a lever J
thereon and fit the profile I to slide in guides in a radial slot in the puliey as

page_text: indicated in Figures 3 and 4. The end movement of the cone K tilts the lever J'
which acts on the tool I and presses the tool i towards the longitudinal centre
line of the stud B. As the cone is withdrawn the lever J is retracted by an
elastic band i¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of parts forming the improved apparatus for shaping clay
ware substantially as herein described.
2. In a machine for shaping clay ware the combination of a central stud and
carrying block supporting the article to be operated on, and a rotating pulley or
tool holder carying a shaping tool or profile arranged to act to a greater or less
extent on the article substantially as herein described.
