PROVISIONAL SPECIFICATION.
Improvements in or relating to Movable Brake Shoe Holders.
I, ALPHONSE MOREAU, Manufacturer, of Oradour-sur-Vaynes, Department of
Haute-Vienne, in the Republic of France, do hereby declare the nature of this
invention to be as follows:
This invention relates to a movable brake shoe holder for carriage wheels
which allows of regulating the brake shoe rapidly and easily and secures the
friction of the whole surface of the brake on the circumference of the wheel during
the whole time when the brake remains pressed and maintains this shoe vertical
when the brake is loosened.
This movable brake shoe comprises the following pieces:-
A cylindrical iron rod connected to the brake.
A sole of cast iron receiving the shoe on one of its sides, and presenting on
the other side two ears traversed without friction by the rod. The sole has also
two oblong transversal openings for the passage of the screw rods or bolts serving
for the fixing of the shoe.
A cast iron ring is placed freely between the ears of the sole and traversed
without friction by the rod. This ring has a projection which serves to maintain
the shoe in a nearly vertical position when the brake is loosened.
A pressure screw serves for fixing the ring on the rod when this ring is in
the desired position.
An iron key is placed between the rod and the end of the screw for the purpose
of distributing the pressure of this screw and of preventing injury to the rod.
As soon as the screw is loosened, the shoc carrier being movable along and
round the rod, the regulating to the periphery of the wheel is nearly instantaneous.

Improvements in or relating to Movable Brake Shoe Holders.
I, ALPHONSE MOREAU, of Oradour-sur-Vayres, Department of Haute-Vienne,
in the Republic of France, Carriage Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described in and by the following statement:-
This invention has for its object a movable brake-shoe holder for carriages
and other vehicles which enables one to easily and rapidly adjust the brake shoe

page_text: relatively to the wheels, assuring the friction of the whole surface of the said
brake shoe on the rim of the wheel during all the time that the brake is in action
and keeping the brake-shoe in about a vertical position when the brake is
removed. This movable brake shoe holder is particularly remarkable:
1. because it can hold rigidly any shaped brake shoe or block which is taken
off as it becomes worn without the said brake shoe holder being at all damaged ;
2. because it does not comprise any weak organ such as a spiral metallic spring
or plate spring; 3., because its action or rotation on its axle bearing cannot be
accidently interrupted at any moment; and 4. because it can be instantaneously
removed from this axle and can be replaced in the same manner. This removable
brake shoe holder constitutes thus a most strong and easily manageable apparatus
which allows of a very efficient brake action.
When the brake is out of action, the brake shoe is held in about a vertical
position by a special arrangement of the brake shoe holder, so that this brake
shoe comes rapidly in contact with the wheel, through its whole length as soon
as the brake is put in operation.
In the annexed drawing I have shown a model of my movable brake-shoe
holder.
Fig 1 is a front view; Fig. 2 is a horizontal section on the line 1-2 of Fig. 1;
Fig. 3 is a side view of Fig. 1; Fig. 4 is a vertical section on the line 3-4 of
Fig. 1; Fig. 5 is a section on the line 5-6 of Fig. 3.
My movable brake-shoe holder comprises the following parts.
1. A cylindrical iron rod a in connection with the brake handle and serving
as a bearing for the other parts of the brake shoe holder;
2. A malleable iron plate or shoe b on one of the faces of which is adapted the
brake shoe or block and which is provided on its other face with two ears or
projections cc loosely traversed by the rod a. The brake shoe, which may be
of any shape, is fixed on the shoe or plate 6 by means of bolts, screws, or in any
other suitable manner, and the shoe or plate 6 has for this purpose two transverse
slots d d.
3. A cast iron socket f loosely set between the ears or projections of the shoe
or plate 6 and traversed by the rod a. This socket has a projection f¹ which
serves to keep the shoe b in about a vertical position when the brake is loosened.
4. A set screw 9 which serves for fixing the socket f on the rod a when this
socket has been adjusted at the required position.
5. An iron key h located in the thickness of the socket f and kept between
the rod a and the end of the screw g in order to distribute the pressure of this screw
on a larger surface and to avoid any damaging of the rod a.
The shoe band consequently the brake shoe being thus movable around the
axle a, it results that during any vertical displacement of the bearing rod a on
account of the variations of the load on spring vehicles or on account of the
jolting, the brake shoe follows always exactly the curve of the wheel and bears
against this wheel upon its whole periphery.
My brake shoe holder has besides the advantage of not needing a special shape
of brake shoe and of being of very simple constructions and easy of adjustment.
It can be understood that as soon as the screw g is loosened, the brake shoe
holder being movable along and around the rod a, its adjustment opposite the
rim of the wheel can be almost instantaneous.
I reserve to my self any change in the forms and sizes of my movable brake
shoe holder and to apply it to all sorts of vehicles, carriages, carts, motor cars, etc.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
-
1. A brake shoe holder for carriages and other vehicles adapted to have double
movement around its bearing rod and along this rod, so that when it has been

page_text: brought exactly opposite the rim of the wheel by its lateral movement, it is
secured in its proper position by a socket kept between its two ears or projections
and by a set screw and preserves its mobility around its bearing rod in order to
become automatically adjusted so as to be concentric to the wheel, substantially
as hereinbefore set forth.“
2. A movable brake shoe holder according to Claim 1, composed of a metallic
shoe b which receives a brake shoe or block on one of its faces and which has on
the other face two ears or projections c c loosely traversed by the cylindrical
bearing rod a connected with the brake handle, and a metallic socket f kept
between the two projections of the shoe and loosely traversed by the cylindrical
bearing rod a upon which it is fixed in the required position by means of a set
screw and a key h located in the thickness of the socket and kept between the
rod a and the end of the screw g, substantially as herein before described and
illustrated in the accompanying drawings.
3. A movable brake shoe holder according to Claim 1, provided with a shoe b
which receives the brake shoe or block on one of its faces and which has on the
other face two ears or projections c c loosely traversed by the cylindrical bearing
rod a connected with the brake and a metallic socket f provided with a heel or
projection f¹, located between the two projections of the shoe and loosely traversed
by the cylindrical bearing rod a upon which it is fixed by means of a set screw,
substantially as hereinbefore described and illustrated in the accompanying
drawings.
