Improvements in and relating to Tile Presses.
I, ANDERS MARTINUS STRUSHOLM, a citizen of the United States of America,
residing at Woodbridge, in the County of Middlesex and State of New Jersey,
one of the United States of America, Gentleman, 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 has relation to ornamental tile presses, and consists in the novel
construction and arrangement of its parts.
In the accompanying drawings-
Figure 1 is a perspective view of my invention.
Figure 2 is a side view of the same.
Figure 3 is a sectional view, and
Figures 4, 5, and 6, are detail views.
My invention is described as follows:
It consists of a table, 1, having mounted on its top the two sets of perpendicular
guides, 2, 2, the upper ends of which are connected by the cross bar, 3, which
in turn is provided with a perforated ear, 4, and in the middle of said cross bar is a
threaded perforation in which works a screw, 5. Said screw has rigidly secured to
its upper ends the arms 6, 6, which have welded or otherwise secured to their
extreme ends the weights or balls, 7, 7. The lower end of said screw is loosely
journaled in the middle of a moving cross bar, 8, the ends of which extend through
the guides on either side and are provided with the perforations, 9, 9, (see Figure 3).
Said cross bar, 8, has on its under side in its middle, a socket, in which is located
a detachable die, 10.
To the top of the cross bar 3, just over the top of the guides 2, is secured, one on
each end, the elevated perforated shoulders, 11, 11, which are adapted to loosely
hold in their perforations the upper ends of the perpendicular rods, 12, 12, which
in turn pass down through the perforation in the cars, 4, of the cross bar, 3, and
through the perforations 9, in bar, 8, and their lower ends are pivoted to the upper
outer ends of the crank levers, 13. The upper ends of said rods are provided
with a thread and nut, 14. The thread working through the perforation in
shoulder 11, and the nut working against the under side thereof.
The spring, 15, works around the rod, 12, between the underside of the nut, 14,
and the upper side of the cross bar, 8; and working around the lower end of
said rod, 12, between the underside of the cross bar, 8, and the adjustable collar, 16,
is the spiral spring, 17.
The crank lever, 13, consists of the horizontal rod and the perpendicular rod,
which are integral with each other and pivoted at 18, (see Figure 3).
The lower ends of the perpendicular rods of said crank lever work in a perfora-
tion in the rods, 19, 19.
To the inner ends of said rods, 19, 19, are secured by screws or otherwise, the
rear ends of the forks, 20. The teeth of these forks enter perforations in the sides
of the mould, 21, and they are provided with suitable shoulders to prevent them
entering too far into the mould, and the longitudinal edges of the teeth are bevelled
as shown in Figure 6. This fork may have any number of teeth according to the
length of the tile to be pressed.
Preferably I use a mould, as shown in Figure 4, but the style of mould is
immaterial.
My invention is also provided with the usual treadle by which the tile is lifted
from the surface of the table after it is pressed, and as there is nothing novel in
this feature, it is superfluous to go into detail to explain it.

page_text: My invention is operated as follows :-
The clay is placed in the mould and the arms, 6, 6, are swung around, which
causes the die, to descend and enter the top of the mould. As.the cross-bar, 8,
descends, the springs, 17, 17, become compressed, and the teeth of the forks, 20,
are forced into the mould up to the shoulders, which will make slots in the under-
side of the tile which will have bevelled sides corresponding to the bevelled edges of
the forks.
When the tile is sufficiently pressed, the arms 6, 6, are swung around in the opposite
direction, this will first lift the die from the tile, and as the cross-bar, 8, ascends
the springs, 15, 15, will become compressed, which will lift the upright rods 12, 12,
which in turn will pull the forks out of the tile, but not out of the mould. The
treadle is pressed with the foot, and the tile is lifted out of the mould and
removed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A tile press consisting of a descending cross bar, 8, having perforated ends,
upright rods, 12, 12, working through the perforations in cross bar, 8, said rods
having their upper ends threaded and provided with the nuts, 14, 14, and their
lower ends provided with the adjustable collars, 16, 16, and pivoted to the
levers, 13, 13; springs, 15, 15, working around rods, 12, 12, between the under
face of nuts, 14, 14, and the upper face of cross-bar, 8; springs 17, 17, working
around rods, 12, 12, between the under face of cross-bar 8, and the upper faces of
collars, 16, 16; pivoted crank levers, 18, 18, the lower ends engaging the bars, 19, 19,
and forks, 20, 20, secured to the bars, 19, 19; substantially as shown and described.
2. In a tile press, the combination with a movable cross-bar, 8, carrying a die
thereon, of sliding forks, and a spring connection between the forks and the
descending cross-bar, substantially as described.
3. In a tile press, the combination with a mould, of a movable cross-bar carrying
a die thereon, sliding rods, forks projecting into the said mould, crank levers
connecting the said rods and forks, and springs secured to the said rods and bearing
on the said cross-head, substantially as described.
4. In a tile press, the combination with a mould, of a movable perforated cross-
head carrying a die thereon, rods having enlargements thereon passing through
the perforations in the said cross-head, springs surrounding the said rods and
interposed between the said cross-head and the said enlargements, forks adapted to
be projected into the said mould, and crank levers having their opposite arms
connected with the said rods and forks, respectively, substantially as described.
