IMPROVEMENTS IN THE CONSTRUCTION OF COLLIERY CORVES AND OTHER SIMILAR VEHICLES
Year: 1881

page_text: LETTERS PATENT to Joseph Trippett and Frederick Hallam, both of Sheffield,
in the County of York, for an Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF COLLIERY CORVES AND OTHER SIMILAR VEHICLES."
PROVISIONAL SPECIFICATION left by the said Joseph Trippett and
Frederick Hallam at the Office of the Commissioners of Patents on the
30th September 1881.
JOSEPH TRIPPETT and FREDERICK HALLAM, both of Sheffield, in the County of
York. "IMPROVEMENTS IN THE CONSTRUCTION OF COLLIERY CORVES AND OTHER
SIMILAR VEHICLES."
This Invention relates to the construction of colliery corves and other similar
vehicles.
As ordinarily constructed the side frames of the corves are of wood, having
buffer hoops or shoes, and are consequently weak, and the pedestal bearings are
bolted thereto, and there is little or no provision for a supply of lubricating
material.
Our Invention consists in making the said side frames of metal, preferably cast
steel or malleable cast iron, and having in combination therewith the buffers,
pedestals, and oil or grease boxes and pockets for the end frames, bosses for the
tie rods, and with or without an upper flange (or flanges), to which can be secured
the side (or side and end) boards or sheets. The metallic frame can be in two or
more parts joined together by bolts and packings, or it may be in one piece.
The side frames may be connected by wood end frames and tie rods in the
ordinary manner.

In the accompanying two Sheets of Drawings, Fig. 1 (Sheet 1) is a front view
in elevation, and Fig. 2 is an end view in elevation of a colliery corve with outsido
bearings fitted with our improved metallic frame. A, A¹, is the frame in two parts
joined by bolts M and with elastic packing C; the half of the side frame A is
shown with an oil or grease box B having a hinged lid, and the half of the side
frame A¹ (as a modification) is shown with an oil or grease box B having a sliding
lid E; G, G¹, are the steps or brasses which are fitted into the horn or pedestal
plates or guides J, which are cast with and form part of the side frame; H, H¹, H*,
show three of the four wrought iron corner bolts or staves which secure the top
frame of the corve to the metallic side or under frame A; K, K¹, show front and
end views of a wood corve body, the vertical stancheons or frames of which are
let into the top flange of the metallic side frames A, as shown at L, the said flange
being thickened for that purpose; N shows one of the horizontal tie rods which
secure the metallic side frames A in position; O, O', 0, 0³, (Fig. 2, Sheet 2) are
pockets in the side frame to receive the ends of the wood cross ties, as shown at P
(Fig. 2, Sheet 1).
The same letters of reference refer to the same detail parts in each view.
Fig. 1 to Fig. 10 (Sheet 2) show detail views of our improved metallic frames;
Fig. 1 is a front view in elevation, the left half of the frame A being shown with a
hinged lid D to the oil or grease box B, and the right half A' (as a modification)
being shown with a sliding lid E to the oil or grease box B; Fig. 2 is a back or
inside view in elevation of the opposite frame A3, A3; Fig. 3 is a top view or plan;
Fig. 4 is an under view (looking upward from the ground) of the sido frame A, A';
Fig. 5 is a left end view of the half frame A¹ (Fig. 1) looking from left to right;
Fig. 6 is a vertical section of the frame A' as taken through the dotted line Y, Z,
(Fig. 1); Fig. 7 is a left end view of the frame A' (Fig. 2) looking from left to
right.
Fig. 8 is a vertical section of the frame A³ as taken through the dotted line
W,X, (Fig. 2) and looking from left to right.
Fig. 9 is a vertical section of the frame As as taken through the dotted line
T, V, (Fig. 2) and looking from left to right,

page_text: Fig. 10 is a vertical section of the frame A³ (Fig. 2) as taken through the dotted
line R, S, and looking from left to right..
A, A¹, are the two halves of one side frame of a corve; B, B¹, are the oil or
grease boxes forming parts of the half frames A, A'; C is the elastic packing of
india rubber, leather, or other suitable material; D is the hinged lid of the grease
box B; E is the sliding lid of the grease box B¹; G, G', are the brass steps or
bearings fitted into the pedestals or horn plates J, J; M, M, are the bolts which
secure together the two half frames A, A¹; Q, Q', are bolts fitted to the pedestals
J, J', to prevent the corve being raised out of its bearings. With our improve-
ments the use of separate buffer hoops, as hitherto fitted to corves with wood
frames, is obviated, and the pedestal, cast with the frame, is so formed that the
brasses or bearings used therewith are interchangeable. The improved frames can
be made so that the corve will rest on the axle between the wheels instead of
outside, as illustrated by the accompanying Drawings, and without departing from
the essential features of our Invention.
The flanges can or will be cast with bosses for the transverse and vertical tie
rods and for the upright frames of the corve body.
The extreme ends of the frames can or will be formed with pockets for the
insertion of blocks of wood or other suitable material for buffing.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the herein-before
in part recited Letters Patent is,―
The construction of the frames of colliery corves and other similar vehicles with
the oil and grease boxes, and the pedestals or horn platos and solid buffers or buffer
pockets formed therewith, and with or without pockets, recesses, or bosses for the
cross timbers, tie rods, and vertical framework of the corve body, and with or
without an upper flange for securing the boards or sheets of the corve body, the
said frame being made in one piece from end to end, or being made in parts and
joined together with an elastic joint, substantially as herein-before specified and
as illustrated in Fig. 1 and Fig. 2 (Sheet 1), and Fig. 1 to Fig. 10 (Sheet 2) of the
accompanying Drawings.
In witness whereof, we, the said Joseph Trippett and Frederick Hallam, have
hereunto set our hands and seals, this Twenty first day of March, in the
year of our Lord One thousand eight hundred and eighty two.
