Year: 1876

page_text: LETTERS PATENT to John Hancox, of Hungerford, in the County of Berks,
Foreman to Messrs. Cottrell and Co., Engineers, for the Invention of "IM-
PROVEMENTS IN ELEVATORS OR APPARATUS FOR RAISING WHEATSHEAVES,
STRAW, HAY, AND OTHER SUBSTANCES."
ealed the 1st December 1876, and dated the 2nd June 1876.
PROVISIONAL SPECIFICATION left by the said John Hancox at the Office of
the Commissioners of Patents on the 2nd June 1876.
JOHN HANCOX, of Hungerford, in the County of Berks, Foreman to Messrs.
Cottrell, and Co., Engineers. "IMPROVEMENTS IN ELEVATORS OR APPARATUS FOR
RAISING WHEATSTEAVES, STRAW, HAY, AND OTHER SUBSTANCES.'
In the Specification of Letters Patent, No. 2666, granted the 9th day of August
1873 to William Charles Cottrell, there is described an elevator or apparatus for
raising wheatsheaves, straw, hay, and other substances, which elevator is constructed
with a folding trough in two parts, provided with a slotted sliding joint arranged
to prevent undue tightening or stretching and consequent breakage of the rack
chains when folding up or closing together the component lengths or parts of the
trough.
Now the present Invention relates to the troughs of such elevators, and consists
in a method of constructing the lower length of trough in two parts or sections,
the one arranged to slide for a certain distance within the other so as to obtain a
greater length of trough without increasing the length of the elevator carriage.
For this purpose the upper portion of the lower length of trough is constructed
with a part capable of sliding in the lower portion, and arranged to slide within
the latter when operated by means of racks and pinions provided for the purpose,
one rack and pinion being arranged at each side of the sliding portion of trough.
The pinions are keyed on a spindle arranged to be worked by spanners fitting on to
the ends of the spindle. The sliding portion of the trough is kept in its extended
position relatively to the lower portion of the trough by means of bolts provided
with plates and screwed handles or nuts arranged to be tightened up as required.
Price Gd.l

page_text: When these screwed handles or nuts are unscrewed the sliding portion of the trough
is free to be moved lengthwise, either for lengthening or shortening the compound
trough as the case may be.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Hancox in the Great Seal Patent Office on the 1st December
1876.
JOHN HANCOX, of Hungerford, in the County of Berks, Foreman to Messrs.
Cottrell and Co., Engineers. "IMPROVEMENTS IN ELEVATORS OR APPARATUS
FOR RAISING WHEATSHEAVES, STRAW, HAY, AND OTHER SUBSTANCES."
In the Specification of Letters Patent, No. 2666, granted the Ninth day of August
1873 to William Charles Cottrell, there is described an elevator or apparatus for
raising wheatsheaves, straw, hay, and other substances, which elevator is constructed
with a folding trough in two parts provided with a slotted sliding joint arranged
to prevent undue tightening or stretching and consequent breakage of the rake
chains when folding up or closing together the component lengths or parts of the
trough.
Now the present Invention relates to the troughs of such elevators, and consists
in a method of constructing the lower length of trough in two parts or sections, the
one arranged to slide for a certain distance within the other so as to obtain a
greater length of trough without increasing the length of the elevator carriage.
Fig. 1 shews in side elevation so much of an elevator as is needful to illustrate
the manner of carrying out the Invention.
Fig. 2 is a plan view of parts of the trough shewing the fastening of the sliding
part to the other part of the lower or compound length of the trough.
Fig. 3 is a plan of the under side of the lower or compound length of trough
shewing the positions of the adjusting racks.
Fig. 4 is a cross section taken in the line A, B, of Fig. 2, giving in detail the
mode of fastening the sliding part to the other part; and
Fig. 5 is a cross section through the main frame shewing the positions of the
rack pinions.
The upper portion (a) of the lower length of trough is constructed with a part (b)
capable of sliding in the lower portion (c), and arranged to slide within the latter
when operated by means of racks (d) and pinions (e) provided for the purpose, one
rack and pinion being arranged at each side of the sliding portion of trough, as
shewn. The pinions (e) are keyed on a spindle (f) arranged to be worked by
spanners fitting on to the ends (g) of the spindle. The sliding portion (b) of the trough
is kept in its extended position relatively to the lower portion (c) of the trough by
means of bolts (4) provided with plates (i), wood blocks (k), and screwed handles (7)
(or nuts) arranged to be tightened up as required. When these screwed handles or
nuts are unscrewed the sliding portion of the trough is free to be moved lengthwise,
either for lengthening or shortening the compound trough as the case may be. The
iron plates and blocks form grooves for guiding and steadying the sliding
portions of the trough.
This Invention may obviously be applied to elevators of various constructions.
And having now described the nature of the said Invention, and explained in
what manner the same is to be or may be performed or carried into practical effect,
I hereby declare that I do not claim as of my Invention or the exclusive use of any
of the mechanical parts herein-before described and shewn, when considered
separately and apart from the combination or application thereof in manner and for
the purpose specified, but what I consider to be novel and original and therefore
claim as the Invention secured to inc by the herein-before in part recited Letters

page_text: Patent is, the combination of parts constructed, arranged, and operating as described
and shewn whereby the length of the elevator trough is made adjustable by the
sliding of the one part of the trough within the other."
In witness whereof, I, the said John Hancox, have hereunto set my hand and
seal, this Twenty-ninth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
JOHN HANCOX. (L.S.)
