Complete Specification Left, 28th July, 1900-Accepted, 29th Sept., 1900
Medical Percussion-hammer with Pencil.
I, JULIUS MÜLLER, of Kenzingen, in the Grand Duchy of Baden,, Germany,
Practising Physician, do hereby declare the nature of this invention to be as
follows:
This invention relates to an advantageous combination of the medical per-
cussion-hammer with a plain or coloured pencil or dermatograph (as often
styled).
Heretofore, these have had to be carried as separate instruments with the
result that commonly enough the advantage of noting affected parts point by
point by the pencil has been foregone, or made from memory, the pencil itself
being left at home.
The exact medical examination now more than ever demanded is greatly
facilitated if the limits of affected parts as determined by percussion are at
once traced upon the skin, and therefore it is highly desirable that the appropriate
pencil should be always at hand. Alternative bringing and leaving behind of
this implement is vexatious and wastes time, so that for long it has been a
desideratum to have both instruments united in one. The object of my inven-
tion is to provide such union so effected that without additional weight each
instrument can be conveniently manipulated.
The invention consists in the adjustment of a pencil on the opposite end of
the hammer head or, better still to slide up and down within the handle.
In the accompanying drawing in which like letters denote like parts.
Figure 1 gives a view of my invention with its appurtenances in two com-
pleted forms.
Figure 2 shows in two representations full details of how the pencil can be
arranged to slide in the hammer handle of Figure 1.
In Figure 1, (A) is the hammer and (a) the handle, while (b) betokens the
pencil which as per the dotted lines is adjusted on the opposite end of the
hammer head. More serviceable is the arrangement of the pencil in the
hammer handle, as shown by the continuous lines.
.
To serve this purpose the hammer handle is hollowed out and the pencil in
its normal state is placed therein, projecting only just far enough to be caught
by the fingers and drawn forward. But that the pencil may be held steady
at any place a spring (c) is fixed within the handle (a) which presses strongly
on the broad opposite side of the pencil. For the better manipulation and
sliding of the pencil in the handle there may as well. however, be screwed into
the pencil a pin (e) carrying on its outer end a head (d) convenient for handling.
A slit (a) in the handle, wherein the pin (e) works up and down provides that
a proper length of pencil shall be available during use.

I, JULIUS MÜLLER, of Kenzingen, in the Grand Duchy of Baden, Germany,
Practising Physician, 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 an advantageous combination of the medical per-
cussion hammer with a plain or coloured pencil or dermatograph (as often
styled).
Heretofore, these have had to be carried as separate instruments with the
result that commonly enough the advantage of noting affected parts point by
point by the pencil has been foregone, or made from memory, the pencil itself
being left at home.
The exact medical examination now more than ever demanded is greatly
facilitated if the limits of affected parts as determined by percussion are at
once traced upon the skin, and therefore it is highly desirable that the appropriate
pencil should be always at hand Alternative bringing and leaving behind of
this implement is vexatious and wastes time, so that for long it has been a
desideratum to have both instruments united in one. The object of my inven-
tion is to provide such union so effected that without additional weight each
instrument can be conveniently manipulated.
The invention consists in the adjustment of a pencil on the opposite end of
the hammer head or, better still, to slide up and down within the handle.
In the drawings left with the Provisional Specification wherein like letters
denote like parts.
Figure 1 gives a view of my invention with its appurtenances in two com-
pleted forms.
Figure 2 shows in two representations full details of how the pencil can be
arranged to slide in the hammer handle of Figure 1.
In Figure 1, (A) is the hammer and (a) the handle, while (b) betokens the
Dencil which as per the dotted lines is adjusted on the opposite end of the
hammer head. More serviceable is the arrangement of the pencil in the
hammer handle as shown by the continuous lines.
To serve this purpose the hammer handle is hollowed out and the pencil in
its normal state is placed therein projecting only just far enough to be caught
by the fingers and drawn forward. But that the pencil may be held steady
at any place, a spring (c) is fixed within the handle (a) which presses strongly
on the broad opposite side of the pencil. For the better manipulation and
sliding of the pencil in the handle there may as well. however, he screwed into
the pencil a pin (e) carrying on its outer end a head (d) convenient for handling.
A slit (a) in the handle, wherein the pin (e) works up and down provides that
a proper length of pencil shall be available during use.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
-
A medical percussion hammer combined with a pencil or dermatograph as
above so that the combination is practically one instrument.
