SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Peter Jensen in the Great Seal Patent Office on the 13th January 1877.

These improvements are as follows, and are illustrated by the accompanying
Sheet of Drawings, of which Figure 1 is a vertical longitudinal section; Figure 2,
a vertical transverse section; and Figure 3, a detail of a machine constructed
according to this Invention.
The material for the brick or other article to be moulded is put into a box or
mould A and pressed by means of a pressing ram or piston B, which moves in
guides C, C, and is worked by a connecting rod D and crank shaft E. The
machine is actuated by means of fast and loose pulley F, F1, on a shaft G, which
carries a pinion H gearing into a wheel K on au intermediate shaft I, which also
carries a pinion L gearing into a wheel M on the shaft E.
The clay is fed into the machine during the return stroke of the piston from a
hopper, shoot, or passage N, above which a pugging or mixing appliance may be
placed, if required, and as here shown, and which may consist of a horizontal
spindle P, provided with knives and enclosed in a cylinder Q, which is supplied
from a hopper R. The pug-mill shaft is worked from the pinion L on the aforesaid
intermediate shaft by means of a wheel 1. A brick or tile having been formed
and the superfluous material, if any, squeezed back into the shoot N by an outlet
thereinto formed at a, the mould A turns upon its axis one-fourth of a turn, so that
the brick is turned downwards; this is effected by a cam disc s on the crank
shaft E, provided with a groove b, in which works a pin c fitted to a lever or
link T, which thus is pushed backwards and forwards, one end of it being guided
by its fork-shaped end on the crank shaft, the other end taking on to a pin d on the
mould box A; the further end U of this lever T is bent up, and a small lever vis
here jointed on to it, the slotted lower end of which is connected to a rod w, that
by means of the studs f, f1, is connected to a plate e forming the bottom of the
mould A. While the mould is turned the rod w will slide in the slot of the lever v,
and as soon as the moulded brick has got away from the piston the rod will have
reached the end of the slot, and being pushed by the small lever thrust the brick
out of the mould. In order that the rod be not pushed down so as to produce a
canting action there are on the other side of the mould provided a corresponding
lever T, pin d, and small slotted lever v¹. The moulded brick then falls on an
endless band E, which is worked from the crank shaft E by means of strap
pulleys m and n.
A steam pipe y is provided having a stoppered perforated end, and leading steam
into the pug mill or other part of the machine above the pressing mould.
And having thus fully described the nature of this Invention, I declare that
I claim
Firstly. The mechanism for actuating the pressing mould, constructed and
operating substantially as set forth.

page_text: Secondly. The mechanism for pushing the moulded article out of the mould,
constructed and operating substantially as set forth.
Thirdly. The application of steam to the material to be operated on in machinery,
constructed substantially as described and shewn.
In witness whereof, I, the said Peter Jensen, have hereunto set my hand and
seal, this Twelfth day of January, in the year of our Lord One thousand
eight hundred and seventy-seven.
