SALVATORE BELLOTTI, Engineer, and Count GRÉGOIRE DE CHOCH, both of No. 51,
Rue des Petites Ecuries, in the City of Paris, Republic of France. "AN IMPROVED
APPARATUS FOR MENDING, JOINING, OR FISHING BROKEN SHAFTS, POLES, AXLES,
MASTS, CONNECTING RODS, AND OTHER FRACTURED PIECES."
The object of our improved apparatus is the immediate, and, so to say, instan-
taneous mending or joining together of broken shafts or poles of carriages, axles,
carriage springs, shafts of ambulance litters, et cetera. It may also be applied to
the repairing of the masts, oars, and rudders of ships, telegraph posts, ladders,
scaffoldings, driving shafts, connecting, rods of engines, and to every kind of rod
liable to breakage.
The great feature of our improved splints or fishes is that they do not need to be
made for this or that thickness of pieces, the necessary adjustment for obtaining the
proper pressure for joining and binding the two parts taking place directly the
apparatus is applied; therefore with a few different sizes of splints, broken pieces of
any dimensions may be repaired.
Our system of splint or fish is composed of two, three, or a greater number of
rings or collars opening on a hinge and closed by a screw or catch. These rings are
connected by longitudinal bars, splints, or fishes, some of which form part of or are
cast with one of the two jointed parts of the collars so as to form one whole; the
others, similarly arranged to the first, being attached to the other jointed part of the
collars by screws placed in these latter, the tightening or loosening of these screws
decreasing or enlarging the circle of prehension of the apparatus according to the
thickness of the pieces to be joined. The pressure of the splints is also given by
these screws, which are pointed so that the pieces to be joined are not only held
together by pressure but also by penetration, whereby any longitudinal slipping of
these pieces after being seized by the splint is avoided. The longitudinal bars or
splints might also be provided with pins or projections for the same purpose.
We may in certain cases, for example for bent or curved shafts, fit our apparatus
with bars or splints jointed lengthwise, and we may use round, square, oval, or
other shaped collars.
On the accompanying two Sheets of Drawing, Figures 1 and 2 (Sheet 1) represent
two longitudinal views of an apparatus embodying our Invention at two different
Price 411

page_text: angles, and Figure 3 (Sheet II.) represents an end view of the same. Similar letters
of reference denote similar parts in each of the Figures respectively.
A, A¹, are the parts forming the rings or collars hinged at B, these two parts are
bent over to form flanges at C, C, for closing the collars. For this purpose a tenon
D turns on the flange C¹, its square head E entering a mortise in the other flange C;
by turning the tenon D to an angle of 90° it cannot leave the mortise, and the two
parts of the ring are then closed; F, F, longitudinal iron bars or splints, wrought or
cast with the part A of the collars; G, G₁, screws turning in the part A of the
collars. The head H. of these screws is squared, so that they may be turned by a
key, and the other extremity ends in a point I to penetrate into the pieces to be
joined by the aid of our apparatus. J, J, longitudinal bars or splints, into which
the ends of the screws G, G, may turn freely, so that by screwing and unscrewing
them with the part A of the collars, these splints J, J; may be brought close to or
moved further from those F, F, in order that the pieces K, K, to be joined may be
firmly pressed by all the splints and form a rigid whole.
As aforesaid, for certain applications of our apparatus the bars, splints, or
fishes may be broken, that is to say, jointed in the direction of their length, or they
may be curved.
The number of collars and bars, fishes, or splints will vary with the strength of
the fastening required.
