page_text: I, PAUL DIETRICH of 3 Nordufer, Berlin, Germany, Manufacturer, 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 railway materials and stock and has for its object
improvements in various constructions which are used in railway traffic.
The improvements relate firstly to a contrivance by means of which a waggon for
the conveyance of long pieces of wood can be changed into an ordinary bogy waggon
and with which the frame R proper does not require any bending, even on uneven
surfaces as the two cars connected with each other through the framing, are adapted,
in vertical direction as well as in horizontal direction to ride on the rails perfectly
independently of each other.
This contrivance is shown in the accompanying drawing by Figs. 5 to 9. Fig. 5 is
an elevation of a long wood car resting on frame M provided with bogies B and
holding device h. Fig. 6 an elevation of the same car changed by putting on the
frame R. Fig. 7 the plan of the latter and Figs. 8 and 9 the plan and side view of
the detachable pivots m m.
To change the long wood car (Fig. 5) into an ordinary truck (Figs. 6 and 7) the
device is removed and the frame R is connected by the horizontal turning pivots
with the frame M.
This manipulation is effected in a most simple and commodious manner.
Through the device M m the platform car R is both horizontally and vertically
perfectly independent of the position of the wheels of the two supporting bogies B.
By the use of detachable horizontal pivots m m screwed to the frame M the
platform is secured against displacement and cannot fall off the pivots, as the frame of
the vehicle keeps it in place.
The second improvement relates to a axle box for railway axles. This axle box is
shown by Figs. 10 and 11. Fig. 10 is a longitudinal section, Fig. 11 a side view of
the journal.
The U-shaped guide box K is secured to the frame of the car by supports t¹ t¹ with
fastening bolts s¹¹ and is filled with elastic material m¹ consisting of prepared cork

page_text: heated in oil or grease, rubber, leather or other suitable material. Against the cushion
so formed rests the axle box A, guided by the side walls K and bolts s¹ s¹, and
provided with a cover D of a suitable construction.
The axle box A is provided with a grease receptacle B which is kept closed above
by a cover plate c.
The cover D of the axle box A is hollowed and serves to receive the greasing
material from the grease box B.
The third improvement relates to a brake and consists in such an arrangement of
certain mechanisms, that the brake, when two cars collide, can be actuated automatically
and also at pleasure by a hand wheel by means of a screw. This automatic braking is
in no way impaired by the two other braking contrivances (lever and screw brake).
In the accompanying drawing Fig. 12 is a longitudinal section and Fig. 13 a plan
of this brake-contrivance.
A¹ is the brake, which can be pressed off or on to the wheels by angle lever w w¹.
w carries pivoted to it a rod s² guided in the tube », in which the rod b, to which is
directly fixed the buffer f is also guided.
When the buffer f receives a thrust the rod b presses on the brake A¹ by means
of s² w¹ w.
This is desirable on inclines of the railway, where the cars move more
quickly than the pulling device and when stopping the foremost cars.
Independent of this automatic brake, but acting on the same brakes are the screw
brakes m² m² and the hand lever brakes h' h¹, which are arranged on both sides of the
car and, notwithstanding their common action on the same brake, can act indepen-
dently of each other or supplement each other.
The hand lever brake h acts on pin t¹ of the buffer rod b and when the hand levers
are sufficiently drawn the loose coupling box t2 abuts against the tube and moves
The screw brake m² acts through the block o on the hand lever h¹ and is adapted to
pull the brake.
the brake.
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 :-
1. The combination of a turning frame M with horizontal detachable turning
pivots m m for the framing R for the purpose of changing a longwood car or other car
provided with turning frame M into a platform car (Figs. 5 to 9).
2. The combination of the axle box A with the casing K filled with elastic material,
the holders t¹¹ with bolts s¹ s¹ for the purpose of elastically supporting and guiding
the axle box A between the walls of the casing K and the bolts s¹¹ (Figs. 10
and 11).
3. The angle lever w¹ w with rod s² guided through tube ¹ the buffer rod 6 for the
purpose
of automatical braking and combined with the hand lever h¹ the loose coupling
box 2, the blocks o and screw brakes m² m² substantially as & for the purpose
set forth.
Dated this 11th day of September 1886.
