Our invention has reference to an improved brick and tile press.
According to our invention the movement and action of the dies is imparted and
controlled by a multiple screw (mounted in the framework of the press) which has
right and left hand threads, this multiple screw is actuated by bevel wheels or
friction gearing; when bevel wheels are employed a large bevel wheel is fixed upon
or secured to the said screw, this large bevel wheel gears with and drives two-
smaller wheels upon horizontal shafts mounted at the right hand and left hand of
the press, these shafts also carry friction clutches driven by pulleys and belts from.
any convenient motor.
The said friction clutches are put in and out of gear by means of levers worked
by the foot, by hand, or automatically.

COMPLETE SPECIFICATION.
An Improved Brick and Tile Press.
We, JOHN GILL, and JOHN WILLIAM BURNS, Engineers, of Holbeck Lane,.
in the City of Leeds, Yorkshire, 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:-
Our invention has reference to an improved brick and tile press.
Fig. 1, is a front elevation, aud
Fig. 2, an end elevation of our invention.
According to our invention the movement and action of the dies A and B is
imparted and controlled by a multiple screw C (mounted in the framework D of
the press) which has right and left hand threads E and F, this multiple screw C
is actuated by bevel wheels or friction gearing; when bevel wheels are employed
a large bevel wheel G is fixed upon or secured to the said screw C, this large bevel
wheel G gears with and is driven by two smaller wheels H upon horizontal shafts J
mounted at the right hand and left hand of the press in pedestals J and J' upon
arms Ja and J' upon the framework D. The said shafts also carry friction clutches K
and are driven by pulleys L (with which the said friction clutches engage) and
belts from any convenient motor. The said friction clutches are put in and out of
gear by means of levers worked by foot, or by hand.
The said lever arrangement consists of a treadle lever M, with a foot plate M¹,
the said lever M is pivotted or fulcrumed at N, and connected to vertical rods O,
fixed to shafts P upon which are arms P¹ carrying weights R. To these arms are

page_text: connected the levers S which operate the friction clutches K. For starting the
press by hand a vertical rod T is pivotted to the treadle lever M, and to a hand
lever W, pivotted at V.
X is the fly wheel for giving momentum to the top die A.
The bottom die B, for adjustment purposes, is connected to framework, as 5
ordinary, of which U and U' are the screwed uprights, H² and U³ the cross-bars,
and U and Us pillars connecting the die B to the crossbar U³.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
olaim is :-
1. A brick and tile press having the movement and action of the dies imparted
and controlled by a multiple screw having right and left hand threads deriving its
motion in the manner and for the purposes substantially as set forth.
"
2. In a brick and tile press the combination with the upper die of a multiple
screw, having right and left hand threads, driven by bevel or frictional gearing
from any convenient motor substantially as and for the purposes set forth.
3. In a brick and tile press the combination of the dies A and B, screw C,
framework D, wheel G, wheels H, shafts J, pedestals J' and J2 arms J and J,
friction clutches K, pulleys L, treadle levers M, footplates M', pivots N, rods O
shafts P, arms P', weights R, and levers S, with or without rods T, pivots V, and
hand levers W such as and for the purposes shown and described.
