WILLIAM PHILLIPS THOMPSON, of the Firm of W. P. Thompson & Co., Patent
Agents, of 6, Lord Street, Liverpool, in the County of Lancaster, and of 323, High
Holborn, in the County of Middlesex, Civil Engineer. "IMPROVEMENTS IN AND.
APPLIANCES FOR REPAIRING BROKEN OR CRACKED SHAFTS, BEAMS, SWING BARS,
POLES, YARDS, AND OTHER LIKE OBJECTS." A communication from abroad by
Messieurs Chavignot et Gérard, of Paris, in the Republic of France.
This Invention is designed to enable the driver of a carriage.or other individual
to quickly repair a broken shaft or other straight stem or piece of timber by causing
several collars, bracelets, or bands to solidly embrace all the parts of the carriage
shaft or other stem at the point of fracture. Embraced by 'these collars against the
broken shaft is placed an armature of soft wire or bar metal drawn and annealed
so that it can bend and apply itself to the modification of formn which may result
from the accident. The centre collar is of a larger size so as better to imprison the
fracture. In the case where this fracture is perpendicular, or nearly so, to the axis
of the shaft, the said collar is furnished with interior claws or sharp projections to
bite into the wood. These claws, bent at a right angle out of the substance of the
collar, leave holes for the insertion of nails or wood screws so as to transform the
temporary repair into a permanent one.
The side bracelet collars are constructed of a less size than the large central
bracelet. The number of these bracelets can be augmented at will according to the
nature of the fracture.

page_text: Between each collar is placed a stay abutment piece, stretching piece, or strut.
These stays or stretching pieces are furnished with set screws destined to bite into
the shaft, so as to hold in the most solid manner possible the set of collars against
the shaft by means of the tension brought to bear on the armature.
The collars are made either an entire ring and wedged tight, or in the form of a
horseshoe cottered on to the shaft, or in other form, so that they can be made to
tightly embrace the shaft and armature. One good plan is to make them in two
pieces with flanges, so that they can be bolted together. If a little draw is allowed
the bolts hold them rigidly tight.
This Invention is equally applicable to the poles and swing bars, to the spokes
of the wheels, and to other beams, shafts, or sticks, or rods liable to fracture.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Phillips Thompson in the Great Seal Patent Office on the
4th December 1880.
WILLIAM PHILLIPS THOMPSON, of the Firm of W. P. Thompson and Co., Patent
Agents, of 6, Lord Street, Liverpool, in the County of Lancaster, and of 323, High
Holborn, in the County of Middlesex, Civil Engineer. "IMPROVEMENTS IN AND
APPLIANCES FOR REPAIRING BROKEN OR CRACKED SHAFTS, BEAMS, SWING BARS,
POLES, YARDS, AND OTHER LIKE OBJECTS." A communication from abroad by
Messieurs Chavignot et Gérard, of Paris, in the Republic of France.
I will describe this Invention by giving a literal translation of the Invention as
communicated to me by Messieurs Chavignot and Gérard with orders to file.
"We have designed, under the name of Attelles, an apparatus furnished with
several collars or bands to solidly embrace all the parts of a carriage shaft at the
place of fracture. It is this apparatus that we desire to protect by the present
Patent, referring to the Drawings for full elucidation of the description.
We claim as our Invention the armature of metal A of soft wire drawn out and
annealed so that it can follow on being applied the modifications of form that can
result from the accident; the collar in the centre B of larger size, to the better
imprison the fracture, especially in a case where the fracture is in a plane
perpendicular, or nearly so, to the axis of the shaft, the said collar being furnished
with interior points or teeth to bite into the wood. These points raised at a right
angle leave an opening 61, which permits, if there be room, the fixing of nails or
screws into the wood so as to transform the temporary repair into a permanent one.
The collars or bands C are constructed of size different from that of the large
band B. The number of these bracelets or bands can be augmented at pleasure
according to the nature of the repairs to be executed. The same remark applies
to the number of straining pieces or stays marked D. These straining pieces are
armed with a set screw destined to bite into the shaft to subject the entire set of
collars or bands to a rigid contact with the shaft.

page_text: It is intended that this apparatus shall be equally applicable to carriage poles,
palanquin poles, as well as to the spokes of wheels, and in general poles or similar
articles of all kinds.
Our trademark for this Invention is 'Je maintiendrai' (I maintain), the object
being to recall the cause for which the apparatus is constructed."
Having now given a literal translation of the communication forwarded to me,
I wish it to be understood that while speaking of the soft wire arinature B I do
not confine myself to the use of soft iron wire only, as in some cases bars of iron,
spring steel, or other material could be advantageously used, but that what I
believe to be new, and desire to protect under the herein-before in part recited
Letters Patent is,―
1st. The mode of repairing broken or cracked shafts, beams, swing bars, poles,
yards, and other like objects by binding a yielding armature, preferably of soft
iron wire, thereon by means of collars or bands and struts or straining pieces,
substantially as described.
2nd. The appliances for repairing broken or cracked shafts, beams, swing bars,
poles, yards, and other objects, substantially as herein described, no claim being
made for only one part taken separately, but only for each part as it is used in
combination for the purposes described.
In witness whereof, I, the said William Phillips Thompson, have hereunto set
my hand and seal, this Second day of December, in the year of our Lord
1880.
WM. P. THOMPSON. (L.S.)
