other Materials.
I, HENRY HARRIS, of 21 Trinity Street, Boston, in the County of Lincoln, Hay
Merchant, do hereby declare the nature of said Invention to be as follows:-
My invention relates to an improved machine for compressing trusses of hay, straw,
and other materials, and it consists of a frame work in which a presser plate is adapted
to be moved upwards, or downwards, at will, as hereinafter described, so that when
the said plate is compressing the material upwards, for instance, the lower part of
the machine can be charged, or the previously compressed truss withdrawn therefrom,
or vice versa.
The presser plate is operated through bevil or other suitable gearing, and is
provided with tapped lugs, or eyes, travelling upon vertical screw threaded rods,
fixed at each extremity of the machine, and actuated by the above mentioned
gearing.
The machine is furnished at the top with a cover or counter-plate which receives
the upward thrust of the presser plate, and this counter plate is so arranged as to be
capable of being slidden laterally to the right, or left, through grooves or channels
formed in the upper part of the machine, the object of this arrangement being to
enable the said cover to be withdrawn, while the machine is being loaded from
the top.
In the downward movement of the presser plate, the material is compressed between
the latter and a base plate arranged within the machine. On each side of the
machine I provide two doors to enable access to be had to the compressed trusses,
either at the top or at the bottom of the machine, for the purpose of removing them,
as required.

page_text: Hinged flaps, arranged on each side of the machine, receive and support the truss
withdrawn from the upper part of the machine, in order to facilitate the loading of the
waggon or cart.
The upper doors are each furnished with a support, or supports, upon which the
cover or counter-plate rests, after it has been slidden out for the purpose of loading
the upper part of the machine, as above stated.
If desired, the machine may be mounted on wheels, and may be arranged to be
operated by hand, steam, or horse power.

An Improved Machine for Compressing Trusses of Hay, Straw,
other Materials.
and
I, HENRY HARRIS, of 21 Trinity Street, Boston, in the County of Lincoln Hay
Merchant, do hereby declare the nature of this Invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement (reference being had to the accompanying drawings and to
the letters and figures marked thereon) that is to say :—
My invention relates to an improved machine for compressing trusses of hay, straw,
and other materials, and it consists of a suitable framework in which a presser plate
is adapted to be moved upwards or downwards at will, as hereinafter described, so
that for instance when the said plate is compressing the material upwards in the upper
compartment of the machine the lower compartment thereof can be charged, or the
previously compressed truss withdrawn therefrom, or vice-versa.
The presser plate is operated through bevil or other suitable gearing, hereinafter
described, and is provided with tapped lugs or eyes travelling upon vertical screw
threaded rods mounted at each extremity of the machine, and actuated by the above
mentioned gearing.
The machine is furnished at top with a cover or counterplate which receives the
upward thrust of the presser plate, and this latter is so arranged as to be capable of
being slidden laterally to the right or left, through grooves or channels formed in the
upper part of the framing, the object of this arrangement being to enable the said
cover to be withdrawn while the machine is being loaded from the top.
In the downward movement of the presser plate the material is compressed between
said plate and a base plate, arranged within the machine.
At each side of the machine I provide two doors to enable access to be had to the
compressed trusses, either at the top or at the bottom of the machine, for removing
such trusses, as required.
Hinged flaps, or the like, arranged on each side of the machine, receive and support
the truss withdrawn from the upper part of the machine, in order to facilitate the
loading of the waggon or cart. The upper doors are each furnished with a support,
or supports, upon which the cover or counterplate rests, after it has been slidden
out for the purpose of loading the upper part of the machine, as above stated.
If desired, the machine may be mounted on wheels, and may be arranged to be
operated by hand, horse, or steam power.
And in order that my invention may be readily understood I proceed to describe
the same with reference to the accompanying drawings, in which:
Fig. 1 is a front elevation of my improved machine, Fig. 2 a horizontal section
taken on the line xx of fig. 1, and Fig. 3 a view taken from the rear end of the
machine.
The machine shewn is adapted to be operated by horse power.

page_text: A is the framing in which is the presser plate B adapted to travel upwards or
downwards in said framing, C is the base plate, and D the counterplate or cover
adapted to slide in grooves formed in the upper part of the framing. The presser
plate B is provided at its ends with tapped eyes or nuts c¹, c', travelling over
corresponding screw threaded rods d d¹, one being a right hand screw thread and
the other a left hand screw thread, and said rods are mounted between the upper and
lower cross frames of the machine. These screw threaded rods are here shewn as
projecting beyond the ends of the framing, but if desired they may be set further
back and arranged in openings left between the end framings, or between the
uprights or standards of the end framings, and the tapped eyes or nuts may be
provided with a bearing or arms carrying friction rollers travelling in the openings
between the framings, or between the uprights or standards, so as to ensure the
smooth and easy working of the presser-plate either upwards or downwards.
Instead of using two screw-threaded rods, four may be used, two being placed at
each, end of the machine. The presser-plate is provided on its upper and lower
surfaces with grooves or channels a, a', for the reception of the twine, wire, or cord
for tying the trusses after they have been compressed. The counterplate or cover D,
and the base plate C, are likewise provided with corresponding grooves or
channels a, a, a, a², respectively, for the same object.
Extending beneath the under framing of the machine, and mounted in bearings, is
the main shaft e, on which are keyed bevil wheels ff into which engage respectively
bevil pinions g g', keyed on the lower ends of the screw threaded rods d, d. On this
shaft e, is also mounted a spur wheel h which is caused to engage alternately with
the spur pinions, as hereinafter mentioned. The spur pinion is keyed on the
driving shaft h*, and the spur pinion 2 is keyed on an independent shaft 7³, both of
which are maintained in suitable bearings. The shafts * and ³ also carry,
respectively, other spur wheels hª hª, hª h³°h³ ; hª and hª being of the same size and
serving to transmit the power from the prime motor. The spur-wheels
thrown into gear by any suitable clutch arrangement (not shewn in the drawings
for sake of clearness) when it is desired to obtain power, and the spur wheels hⓇ /
are thrown into gear when it is desired to obtain speed. When working the presser
plate upwards the spur pinion 2 is thrown out of gear by another clutch arrangement
not shewn, but is thrown into gear, and h¹ thrown out of gear when working the
presser plate downwards. At the end of the driving shaft * is a universal joint for
connecting up the horse gear.
are
The gearing herein described and shewn in the drawings is only illustrative of
one method of working the machine, and I do not restrict myself thereto, as it is
obvious that other arrangements of gearing may be adopted which would perform
the same purpose equally well.
E, E¹, E, E, are the doors by means of which access is had to the interior of the
machine, either for charging; or for withdrawing the compressed truss.
G are hinged flaps, or a platform, arranged between the upper and lower doors,
and extending entirely around the machine, or arranged on cach side thereof. On
these flaps, or on this platform, the compressed truss from the upper portion or
compartment of the machine is received prior to transferring it to the waggon
or cart.
H are supports or brackets on the upper doors E, E³, to receive the cover or
counterplate D, when slidden outwards, and it is desired to charge the machine from
the top. Or, if desired, these supports or brackets may be fixed to the framing.
Although I have described and shewn my machine in which the presser plate is
arranged to be worked upwards and downwards, so as to compress one truss upwardly,
and the other downwardly it will of course be obvious that I can arrange the machino
horizontally, so that the presser plate may be worked laterally, in which case when
the said plate is compressing a truss in the left hand portion or compartment, the
right hand portion or compartment may be charged, or the truss previously
compressed may be removed, or vice versa, the gearing being modified to suit this
arrangement.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In machines for compressing trusses of hay, straw, and other materials, the use
of a single presser plate adapted to be moved upwards or downwards, or laterally,
through the intervention of suitable gearing, so that when the said presser plate is
compressing the material in one compartment of the machine the other compartment
can be charged, or the truss previously compressed therein removed, or vice versa,
substantially as herein described.
2. The improved machine for compressing trusses of hay, straw, and other materials,
having its parts arranged, combined, and operating substantially as hereinbefore
described and as shewn with reference to the annexed drawings.
