FRIEDRICH CARL GLASER, of Berlin in the Kindom of Prussia and Empire of
Germany, Engineer and Patent Solicitor. "A NEW OR IMPROVED HORIZONTAL
BAND LOG SAW." A communication from the Firm of Isaakson and Company of
Hamburgh Germany.
This Invention relates to the application of a band saw as a horizontal log saw as
I will proceed to describe by reference to the accompanying Sheet of Drawing, upon
which it will be seen that a transverse support E, such as is usual in horizontal saw
frames, carries the two pivots or axles for the Driving pullies J J of the band saw
and that by means of the screw rods or spindles L L, the bevel pinions M M and
the crank handle H, this support E may be moved up and down. The driving
pulley K is fixed' on one of the aforesaid pivots, and the tightening of the saw is
effected by a known arrangement by means of the hand wheel F. The log of wood
to be cut is carried up to the saw D on the slide carriage A on which it is firmly
held by the claws C, and the movement of the slide is effected by screw gear which
is in connection with a suitable mechanism (such as friction pullies &c) for the
purpose of obtaining a variable motion, according to the dimensions and hardness
of the wood log. GG are friction rollers for carrying the sawblade.
The important advantages which this construction presents as compared with
other horizontal frame saws consist in a larger yield of sawn material and in a
smaller loss of wood.
This latter results from the teeth of this sawblade being less set than in other
cases, inasmuch as here the saw always cutting in one direction only, the saw teeth
are more easily withdrawn from the cut-opening.

by the said Walter Alfred Barlow in the. Great Seal Patent Office on the
19th July 1882.
WALTER ALFRED BARLOW of 6 St. Paul's Churchyard in the City of London
Patent Agent and Engineer. "IMPROVEMENTS IN MEANS FOR EFFECTING ELECTRO-
HYDRO-THERAPEUTIC TREATMENT OF PATIENTS AFFECTED BY DISEASE.". A com-
munication from abroad by Messieurs L. Encausse et Canésie of Paris France.
The system of treating diseases by means of absorption through the skin of
certain medicinal substances has of late years become more and more employed.
In many cases recourse is had to electricity.but in most cases the use of both modes
is indispensable. Meanwhile nobody has yet combined the two treatments in such
a way that all the necessary apparatuses are under hand in the same chamber
which would thus be a complete electro-hydro therapeutic chamber.
The apparatus is disposed in a chamber so that the whole treatment by both the
cutaneous absorption and by electricity is effected in a regulated and simultaneous
or successive manner and this will be done without exposing the patient to any
change in the temperature, which change is always injurious.
In order that the said Invention may be readily understood there is hereunto
annexed two sheets of drawings.
The chamber is constructed as follows:-.
-A steam box A (Sheet 2 Fig 1) made
of wood contains two electrodes a band in the cover of said box is an opening e¹
for the head of the patient. A seat g and a foot stool g' are placed inside the box
upon a false bottom pierced with holes f. The two electrodes are in connection
with a regulator for the control of the volume of the current which may be so
regulated as to be of the strength required.
Steam arrives under the false bottom through a pipe h the end whereof is
furnished with perforations, the condensed steam is carried away by means of a
waste pipe and the steam freed of its moisture is then diffused in the box.
Two air traps 1 and 2 are provided so as to allow a certain quantity of air to
enter thus preventing the temperature becoming too elevated. A box B for
medicinal substances is shown at Fig. 2 Sheet 1 and Fig 2 Sheet 2. Its only new
feature is that it is provided with two steam pipes.
Inside the chamber is placed a ball of vaporization C (shown in Sheet 2 Figs 3
and 4) into which steam arrives through a pipe a and this steam charged with
medicinal chemical substances by its passing through a box containing the said
medicinal substances is then discharged into the chamber by means of a tap B.
The said ball is provided with an automatic blow off apparatus constructed as
follows two washers ✗ perfectly in contact are placed one upon the other and a
float 5 is fixed to the top washer & so as to cause it to turn with it whilst the
bottom washer is fixed and in connection with the blow off pipe & and in the
fixed washer there is a hole corresponding to the said pipe 6.
The movable washer has a slot w which may take a position just over the hole
of the fixed washer and in this latter case the water of condensation which is in
the ball of vaporization is driven off through the blow off pipe . This automatic
blow off apparatus will thus clear the steam of moisture.
A resting couch M (shown in Sheet 1 Fig 4) which may be warmed by means of
a system of pipes D situated under it, is placed in the chamber, there is also a
wardrobe N heated by the same system of pipes D which pipes are also used for
the purpose of carrying steam into the chamber. H indicates a washtand or toilet
table and K a looking glass.

page_text: A regulator G for the temperature of the steam (shown in Fig 5 Sheet 2) is
provided having two springs 8 and 8¹ with tension screws V fixed to two tubes 5
and 6 in line with each other and screwed into a middle piece 7 in which may run
horizontally two slides 9 and 10 upon which press the said tension screws.
Through the expansion of the tubes 5 and 6 under the action of the temperature
the springs 8 and 8¹ approach and also the tension screws which thus act upon the
slides and close the passage of the steam when this latter is too hot.
"There is placed in the chamber A an articulated framed arm-chair (shown in
Fig 6 Sheet 2) for the purpose of treatment by electricity.which arm chair is
composed of movable, pieces which may be placed in any position by means of
thumb screws and. special pieces.x are fixed.anywhere upon the said arın chair for
the purpose of fastening the electric wires.thereto.
The regulator R for electricity is composed of an induction apparatus.so.con-
structed that a regulating button is attached to a bar or rod which may be pushed
in or pulled out and this said bar or rod puts the cylinder in or out of action which
cylinder regulates the strength of the current.
Having now described the nature and particulars of: the said Invention as
communicated to me I claim.
