I, MARK AMOS, of Westbury-on-Trym, in the County of Gloucester, Engineer,
do hereby declare the nature of said invention for "IMPROVEMENTS IN APPARATUS
FOR CRAMPING OR COMPRESSING, APPLICABLE ALSO FOR OTHER PURPOSES," to be
as follows:-
The apparatus constituting this invention consists of two arms or bars each of
which is furnished towards one end with a socket or oye. Each arm or bar is
passed through the socket of the other, both being thus loosely maintained parallel
and free to slide in the sockets. They are slotted or perforated at intervals, and
one arm or bar, which may be conveniently called the front arm or bar, is ranked
or curved at that end towards which tho socket thereof is situated, and a link is
carried thereby. One end of a lever of variablo longth is inserted in a slot or
perforation of the back arm or bar, and by means of a hook hinged to the lever
the latter is connected to the curved end of the front arm or bar. The outer ends
of the arms or bars are, by suitable connections or couplings, secured to frames or
platforms upon one of which is piled or stacked the material which it is desired
to squeeze or compress, the other being placed on the top of the material. By
operating the lever accordingly the outer ends of the arms or bars are brought
nearer to cach other and a compressing strain is thus exerted to compress the
material. Two or more of the compressing devices may be employed to compress
the same mass or bale of inaterial.
By means of a spring catch or pin fitting into the slots or perforations of the
arms or bars compression may be arrested and maintained at any desired degree.
It is intended so to act while the lever aforesaid is transferred from ono slot to
another or from one device to another. The device is also applicable for lifting
weights and for analogous and other purposes. The arms may be made tubular and
arranged to slide one within the other.

I, MARK AMOs, of Westbury-on-Trym, in the County of Gloucester, Engineer,
do hereby declare the nature of my invention for "IMPROVEMENTS IN APPARATUS
FOR CRAMPING OR COMPRESSING, APPLICABLE ALSO FOR OTHER PURPOSES
"and
in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement :—
Apparatus according to this invention comprises, under one form of construction,
a pair of bars each of which is furnished towards one end with a socket or eye.
Each bar is passed through the socket of the other so that the bars are loosely
kept parallel with one another. They are free to slide over the face of one another
in the sockets or eyes. Instead of perforating both of the bars, as described in the
Provisional Specification left with my application for Letters Patent, I prefer to
perforate one bar only with a series of perforations or holes situated at intervals
throughout such part of its length as may be desired. Upon the other bar is
formed a lug or car from which depends a link or shackle into which takes a hook
hinged to a lever employed to actuate the instrument in which, as adapted for
compressing a mass of material, the bars are coupled or connected to frames or
platforms embracing the material placed for compression. The bars may be coupled
to chains, bars, rods, or poles between which the material is placed.
The lever is preferably fork-shaped towards its lower end so as to fit over the
perforated bar. It is furnished with a spring pin for insertion in the holes of
the perforated bar when it is desired to bring the instrument into play. To the
unperforated bar is hinged a spring pawl or catch the spring of which tends to tilt
the pawl so that its lower end which is notched enters the holes of the perforated
bar as they are brought opposite to the notch of the pawl in the operation of the
instrument or apparatus. Thus the pawl serves as a means of maintaining the bars
approximately at the position to which they have been forced while the spring pin
aforesaid is withdrawn for insertion in a fresh hole of the perforated bar for
the purpose of still further compressing the material at the point at which the
apparatus is being applied. Or the lever may be removed to be employed in the
compression of the material at other points without relaxing the compression at
the point whence it is removed. The pawl readily leaves the holes of the
perforated bar in turn as the apparatus is operated, the spring of the pawl yielding
accordingly to the strain exerted.
By the employment of the apparatus above described a compressing strain is
exerted on the inaterial embraced, as aforesaid, between the platforms or frames or
chains or rods to which the bars are coupled or connected.
The apparatus is adapted, among other purposes, for the compression of stacks
or masses of green fodder known as ensilage. The temperature of such stacks
is controlled by regulating the pressure applied for compressing, great nicety in
control being obtained.

page_text: The apparatus may be also employed for compre-sing bales of wool and other
inaterials and for other purposes.
Under a modification adapted for compressing materials contained within a
chamber or analagous receptacle, as for instance, ensilage contained in a silo, the
perforated bar is anchored at the lower end in the floor or in a frame upon the
floor, and is partially embraced by a socket formed in the upper end of a forked
bracket-like compound bar which corresponds to the unperforated bar of the
modification previously described and is fitted with a spring pawl or catch. This
compound bar is made to stand upon a platform which surmounts, as ordinarily,
the mass of material. The hand lever, suspended from a link depending from the
compound bar is actuated to compress the mass by the exertion of a downward
stress upon the platform or cover. After having been compressed to the desired
degree at one point the material is similarly acted upon at other points, there
being a requisite number of anchored perforated bars disposed as desired in the
receptacle.
Referring to the appended drawings, Fig. 1, Sheet 1, represents an end view of
an apparatus constructed and arranged in accordance with my said invention.
Fig. 2, represents a side view, and Fig. 3 a view of the lever by which the
apparatus is operated.
The bars A and B are placed face to face and are loosely kept parallel by the
sockets or eyes a and b formed on one end of each, as shown. The bar A is
pierced at desired intervals throughout any desired extent in its length. Upon the
unperforated bar B is formed the lug or ear c from which depends the link or
shackle d. Into the link d takes the hook e of the lever femployed to actuato the
bars A and B which, as adapted under one method for compressing a mass of
material, are. coupled to platforms or frames, as indicated at Fig. 4, placed above
and below the material or otherwise as may bo suitable.
The lever fis preferably forked towards its lower end so as to fit over the bar A..
The arm g pivotted at g₁ to the lever f is provided towards its lower end with a
pin h which by the action of the spring upon the arm g is caused to extend
across the limbs of the fork of the lever. Pressure exerted by hand inwardly upon
the outer end of the arm g counteracts the said tendency of the spring i and
causes withdrawal of the pin h. Thus the pin his readily transferred from one
hole of the bar A to another in operating the apparatus. To the bar B is hinged
the spring pawl or catch the spring of which tends to tilt the pawl so that its
lower end which is bent or notched enters the holes of the bar A as they aro
brought opposite to the extremity of the pawl as the apparatus is operated. Thus
the pawl k serves to maintain the bars approximately at the point to which they
have been forced while the pin his withdrawn to be inserted in a fresh holo of the
bar A for the purpose of still further compressing the material at the point at
which the apparatus is being applied.
Or the lever may be removed to be employed in compressing the material at
other point without relaxing the compression at the point whence it is removed.
The notch of the pawl k readily leaves the holes of the bar A to pass from one to
the other as the apparatus is actuated, the spring yielding accordingly. The
bar A may instead of being perforated be serrated at one edge so as to constitute a
rack into the teeth or notches of which the spring pawl k would take. Instead of
employing flat bars, as shown in the drawing, tubular arms may be employed one
of which is inserted in the other both arms being free to move in a manner
substantially similar to that in which the flat bars are moved.
Instead of arranging the material which it is desired to compress between
platforms it may be embraced by chains or their equivalent passed at desired
distances apart over bars rods or poles placed longitudinally on the top of the mass
and connected at the bottom to bars rods or poles disposed transversely under the
mass or bale and as the compression proceeds links or lengths of the chains are
taken up accordingly. The connection of the chains or other bands to the platforms,
frames, bars, rods, or poles may be made in various way's.

page_text: If desired the longitudinal and transverse bars, rods, or poles aforesaid may be
dispensed with or those at the top may be retained and those below dispensed with
and vice versa.
In the modification of the apparatus shown in elevation at Fig. 1, Sheet 2, and
in plan at Fig. 2, Sheet 2, it is adapted for compressing material enclosed in a
chamber or receptacle. Fig. 3 Sheet 2, represents a sectional plan of a silo or
chamber for containing ensilage or green fodder and is furnished as shown with
perforated bars A disposed conveniently in the silo. These bars A are anchored at
their lower ends. The compound bar B, Figs 1 and 2, (Sheet 2) which corresponds
to the unperforated arm or bar B of the modification first above described, is fitted
with a link or shackle & and is adjusted in position on the transverse planks N of
the cover or platform by which the material is covered and through which pressure
is brought to bear thereon. The side of the socket of the compound bar B at
which the bar A is received is preferably open. The other side is closed as shewn.
By means of a lever connected to the link d in a manner similar to that herein-
before described with reference to the first modification, pressure is exerted on the
platform and the material below is compressed accordingly.
The spring pawl or catch & pivotted to the compound bar B maintains tho
compound bar and platform at a position to which they have been forced while
the spring pin of the lever is being transferred to a fresh hole. The bolt x
maintains the platform in position when the compound bar B is removed from one
perforated bar to another. The compound bar is so removed after compression has
been effected to the desired degree at any one point. It may then be applied at
any other point, the perforated bars being arranged accordingly.
It will be seen that under both forms of construction the apparatus may be
employed for raising weights or for exerting strains for other purposes.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to bo performed, I declare that what
I claim is
Apparatus for cramping or compressing, applicable also for other purposes,
constructed arranged and operating substantially as hercinabove described with
reference respectively to Figs. 1, 2, 3 and 4, Sheet 1, and to Figs. 1, 2, and 3,
Sheet 2, of the appended drawings.
