PROVISIONAL SPECIFICATION.
New or Improved Machinery for Mixing Mortar for Building
Purposes.
We ROBERT PILGRIM, of 96 Upland Road, Gentleman, and JOHN PEMBERTON,
of 75 Ulverscroft Road, Labourer, both of East Dulwich in the County of London,
do hereby declare the nature of this invention to be as follows:-
This invention relates to machinery for making mortar for building purposes, by
which the mortar is mixed better and more quickly than heretofore.
According to this invention, I have two tanks of suitable form, preferably.
mounted on wheels, and through the first tank, which I term "the lime-runner,'
I pass a spindle on which I fix a number of claws or blades, for mixing the lime
and water, by which the lime is slaked. I also fix a movable sieve on this tank,
and I provide a slide to protect the aforesaid sieve from being damaged by the
claws or blades aforesaid. I also provide a spring blade for clearing the core out
of this tank, and when the lime becomes slaked and fit for use, it is passed into the
second tank, which may be similar in form to the first one. This tank I term the
"mortar-mixer," and this is also provided with a mixer, for mixing the mortar,.
and in this second tank the lime is mixed up with the sand or sand and hair. The
above machinery may be worked by hand or power.
- Suitable outlets are provided in the aforesaid tanks.

New or Improved Machinery for Mixing Mortar for Building
Purposes.
We ROBERT PILGRIM, of 96 Upland Road, Gentlemau, and JOHN PEMBERTON
of 75 Ulverscroft Road, Labourer, both of East Dulwich in the County of London,
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:-
This invention relates to machinery for making and mixing mortar for building
purposes, by which the mortar is mixed better and more quickly than heretofore.
According to this invention, we have two tanks of suitable form, preferably
mounted on wheels; the first one we term the "lime runner"; we fix a moveable
sieve on this tank and a slide to protect the sieve from being damaged. When the
lime becomes slaked, in this tank, and fit for use, it is passed into the second tank,
which may be similar in form to the first one, but is provided with mixing mechanism

page_text: hereafter described, and this lauk we term the "mortar mixer"; in this latter tank,
the lime is mixed up together with the sand and hair or the sand only.
The above machinery may be worked by hand or power.
And in order that our said invention may be better understood we will now
proceed to describe the same with reference to the drawing accompanying this
specification, in which
Fig. 1 shews a front elevation of the lime runner and
Fig. 2 side elevation of the mortar mixer.
Fig. 3 plan of the whole machinery in position.
The same letters denote the same parts in all the views.
a shews the first tank or "lime runner," 6 the second tank, or "mortar mixer."
Both of these tanks are preferably mounted on wheels. A sieve c is fitted to the
lime runner a. el is a moveable cap. A sliding cover d is provided to the sieve c.
Through the mortar mixer & we pass a spindle e on which we fix a number of claws
or blades f. 9 shews a spur wheel, a pinion, and i a hand wheel, for actuating
the blades f.k shews a trap door at the bottom of the mortar mixer 6, opened and
shut by means of the handle l, m is a catch for securing the trap k, n shews a
shoot, broken off at Fig. 1.
The action is as follows:-
The lime is slaked in the tank or lime runner a; the lime may also be mixed in
this tank by means of a larry. The slide d is then drawn up so as to allow the
slaked lime to pass through the sieve c and run into the second tank or mortar
mixer by the shoot, and after having introduced the sand and hair, the shaft e
is rotated either by hand or power so as to mix the mortar by means of the
blades f.
The spur wheel g is keyed on to the shaft e, said wheel engages with the pinion
connected with the hand wheel i which latter may be rotated by the handle o.
When the mortar is sufficiently mixed, the flap or door k is opened so as to
discharge the mortar. In order to open the door k, the lever l'is raised; this
lever works on a rod p which rod also forms the hinge of the flap k; and through
the end of the lever l'another rod p' passes, which rod is fixed to the bottom of the
Hap or door ; it will thus be seen that upon withdrawing the catch m and
raising the lever l, the flap or door will open, the reverse action will close it.
It will be seen that we have shewn the framework of the tanks a and b mounted
on wheels to facilitate their transport we have also mounted the tanks on stages of
different heights (see Fig. 1) the one communicating with the other by means of
the shoot, as shewn at Fig. 3, which is the position we prefer.
The sieve may be changed for one of a coarser or finer mesh as may be desired,
by unscrewing the nuts and taking off the cap c'.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The new or improved machinery for mixing mortar for building purposes.
2. In machinery for mixing mortar the employment of rotating blades fitted in a
tank for the purpose set forth.
