Invention of "IMPROVEMENTS IN BRAKES FOR RAILWAY WAGON WHEELS AND
OTHER REVOLVING SURFACES." A communication from abroad by Julius
Fölsche, of Magdeburg, and Bruno Lange, of Neustadt, Magdeburg, both in the
Empire of Germany.
Sealed the 13th October 1877 in pursuance of an Order of the Lord Chancellor, and
dated the 17th March 1877
PROVISIONAL SPECIFICATION left by the said Arnold Budenberg at the
Office of the Commissioners of Patents on the 17th March 1877..
ARNOLD BUDENBERG, of the City of Manchester. "IMPROVEMENTS IN BRAKES FOR
RAILWAY WAGON WHEELS AND OTHER REVOLVING SURFACES." A communica-
tion from abroad by Julius Fölsche, of Magdeburg, and Bruno Lange, of Neustadt,
Magdeburg, both in the Empire of Germany.
This Invention relates to the construction of a brake especially suitable for
railway wagons, whereby shunting operations may be more speedily and effica-
ciously performed, and also applicable as a brake for other vehicles running upon rails,
and for retarding or stopping the motion of the fly wheels of winding engines and
other revolving surfaces.
As applied to railway wagons this Invention consists of a shaft, mounted hori-
zontally in suitable bearings affixed under the body of the wagon. This shaft
carries at one extremity a weighted hand lever and spring pawl taking into one of
a series of ratchet teeth formed in a stationary bracket; and at its other extremity
the same shaft is provided with a double cam, which by pushing the hand lever in
a contrary direction to that in which the wagon is running, and thus imparting a
partial revolution to such shaft, can be brought into contact with the revolving.
periphery or tyre of the wheel of the wagon, and thus be drawn in or caused to
turn upon its axis, so as to wedge itself fast and act as an effectual brake for
retarding or stopping the motion of the wagon, the return movement of such cam
and shaft being meanwhile prevented by the spring pawl engaging with the ratchet
teeth of the stationary bracket.
It will be readily understood that as the double cam is mounted upon the body

page_text: of the wagon, which is suspended upon springs, that the action of this brake is of an
elastic nature, and that its power for retarding or stopping motion increases in
intensity with the weight in the wagon.
The application of this brake to the other purposes mentioned will bo sufficiently
obvious from the foregoing without further explanation.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Arnold Budenberg in the Great Scal Patent Office on the 17th
October 1877.

ARNOLD BUDENBERG, of the City of Manchester. IMPROVEMENTS IN BRAKES
FOR RAILWAY WAGON WHEELS AND OTHER REVOLVING SURFACES." A com-
munication from abroad by Julius Fölsche, of Magdeburg, and Bruno Lange, of
Neustadt, Magdeburg, both in the Empire of Germany.
This Invention relates to the construction of a brake especially suitable for
railway wagons, whereby shunting operations may be more speedily and effica-
ciously performed, and also applicable as a brake for other vehicles running upon
rails, and for retarding or stopping the motion of the fly wheels of winding engines,
and other revolving surfaces.
In order that this the said. Invention may be the more readily understood, and
carried into practical effect, I have hereunto annexed a Sheet of Drawings
illustrating the improved brake as applied to one of the wheels of a railway
wagon.
Fig. 1 is a side view, and Fig. 2 an end view of so much of a railway wagon as is
necessary to illustrate the application of the improved brake.
Fig. 3 is a side view, and Fig. 4 an end view of so much of another construction
of railway wagon having the improved brake applied thereto.
Similar letters marked on the several views are used to indicate similar parts.
In all the views A is the body of the wagon, and B one of the wheels of the
same; C is a shaft, mounted horizontally in suitable bearings D affixed under the
body of the wagon; this shaft C carries at one extremity a weighted hand lever E,
and spring pawl F, taking into one of a series of ratchet teeth G formed in a
stationary bracket H, and at its other extremity the same shaft is provided with a
double cam I, constructed, by preference, of hard wood, which by pushing the hand
lever E in the contrary direction to that in which the wagon is running, and thus
imparting a partial revolution to such shaft, can be brought into contact with the
revolving periphery or tyre of the wheel of the wagon, and thus be drawn in or
caused to turn upon its axis, so as to wedge itself fast, and act as an effectual brake
for retarding or stopping the motion of the wagon, the return movement of such cam
and shaft being meanwhile prevented by the spring pawl engaging with the ratchet
teeth of the stationary bracket.
In the upright position illustrated in the Drawing the brake is out of gear with
the wheel, and it will be apparent that it is capable of acting in either direction.
J, J, are adjustable stops for preventing the hand lever falling too far, and also
to regulate the locking to the greatest nicety.
It will be readily understood that as the double cam I is mounted upon the body
of the wagon, which is suspend upon springs, that the action of this brake is of
an elastic nature, and that its power for retarding or stopping motion increases in
intensity with the weight in the wagon.
The application of this brake to the other purposes mentioned will be sufficiently
obvious from the foregoing without further explanation.
Having thus particularly described and ascertained the nature of the said Inven-
tion, together with the best methods with which I am acquainted for carrying the
same into practical effect, I wish it to be understood that I do not confine myself

page_text: to the precise details, relative proportions, or dimensions of the several parts, as the
same may be considerably varied without departing from the Invention; but what
I claim is, the combination of the hand lever E, ratchet bracket H, and cam I, as
and for the purposes described, and illustrated on the accompanying Drawings.
In witness whereof, I, the said Arnold Budenberg, have hereunto set my hand
and seal, this 16th day of October, in the year of our Lord One thousand
eight hundred and seventy-seven.
ARNOLD BUDENBERG. (LS)
