page_text: We, LEONARD SHIPWAY HULANDS and HUBERT CHARLES EDWARD HCLANDS,
of Yatton Keynell, Chippenham, Wiltshire, Engineers, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to improvements in appliances for picking up roads,
hard ground, or macadamised surfaces or in that class of apparatus known as
scarifiers.
We carry our invention into practice in manner as follows:-
We attach to either an ordinary self-moving, or traction engine, or to a self-
moving road roller, or any other suitable roller, or vehicle an apparatus designed
as hereinafter described and set forth.
We attach to the axle of the engine, one or more traction bars by preference
we use two traction bars; on each side of the engine or both ends of the driving
axle arranged as will be now described.
The cap or caps of the driving wheel axle is, or are, removed and a sleeve
formed on one end of the traction bar is passed over it, the caps are then replaced
this bar will hereinafter in these presents be called the traction-bar, another
sleeve is fitted over the axle between the horn-block and the boss of the driving
wheel, or in any other suitable place or part other than the axle of the driving
wheel, but in order to avoid the necessity of taking off the driving wheel or for
greater convenience of attachment to other parts of the engine, I prefer to make
this sleeve in halves; these halves being bolted together when they are in their
required positions; the traction bar with the split sleeve will be hereinafter
called, the inside traction bar. Either one, or all of the traction bars can be made
in two parts and bolted together for greater case of adjustment as regards their
lengths.
Across the top of the tender of the engine and more or less parallel to the
driving axle, is fixed by suitable attachments or means; one or more bars such
bars will be hereinafter called, the thrust bars. Attached to the thrust bars is
what will be hereinafter called the trunnion-nut, this nut as its name implies
has two trunnions working in trunnion bearings thus enabling it to move in a
certain required directions about its axis; this trunnion nut is screwed and in
the screw of the trunnion nut is fitted, a spindle or shaft threaded a portion of
its length which will be hereinafter called the regulator shaft the function of the
regulator shaft is to raise or depress what will hereinafter be called the tines or
picks. The tines are fixed to a bar or framing attached to the ends of the traction
bars that is the end furthest from the axle a distance or "A" shaped piece is
carried up from the tine framing and on the top of this A shaped piece or part
of it nearest the thrust bars, is formed a hole hereinafter termed a bearing and
into this bearing is fitted an unthreaded portion of the regulator-shaft: collars
being fitted on the screw both above and below the hearing the regulator shaft
is prolonged so that one end butts against the tine framing, and thus uptakes any

page_text: thrust, and transmits it to the thrust bars. The tines or picks may be pointed
either at one, or both ends or may be arranged in manner as follows,-
"
One tine may be placed at more or less right angles to another somewhat in
the manner of a chevaux de friese;" the tines are fixed to a bar which is free
to revolve in suitable bearings, but at the same time can be fixed in certain
required positions by means of suitable catches or detents; instead of a regulator
shaft as herein before described the tines and attached framing can be raised or
depressed by means of a plunger rod, whose line of action or path is much the
same as the regulator shaft, the plunger rod being fitted at its top or thrust bar
end to a slotted lever, in the slot of which lever works a pin or rofler attached to
the plunger rod; or the plunger rod may be fitted with slings and guides, and a
lever fitted to the sling the lever being kept in certain required positions by work-
ing at the side of, or between quadrant pieces through which quadrant pieces
holes are made at certain required distances and through these holes pins are
arranged so as to keep the lever in certain required positions.
The method of working this apparatus is as follows:-
The engine or other vehicle to which the appliance herein before described has
been attached being placed on the part of the road or ground it is desired to pick
up then by means of the screw or lever the tines are depressed to a desired
point below the surface of the road, the engine is then started and the road is
ripped up by means of the tines ploughing below and through its surface.

Improvements in Machines for Breaking Up Roads and the like.
We, HUBERT CHARLES EDWARD HULANDS, of Yatton Keynell, Chippenham,
Engineer, and LEONARD SHIPWAY HULANDS, of Yatton Keynell, Chippenham,
Engineer, 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; -
Our invention relates to improvements in appliances for picking up roads,
macadamised surface and other hard surfaces.
In order that our invention may be the more clearly understood we annex
hereto one sheet of drawings which are to be taken and read as part of these
presents.
Figure 1. Is a plan of the arrangement for fastening in the picks.
Figure 2, is an end elevation of the entire arrangement fitted to back of engine
tender.
Figure 3 is a side elevation of the arrangement fitted to back of engine tender.
Like letters apply to like parts in all the figures.
B is the back of the tender to which a girder or other suitable crosspiece A is
fixed, this crosspiece is extended to a suitable distance over the outer edge of the
driving wheel H-H'.
To the crosspiece A are fixed brackets I carrying a gimble nut 1) free to move
in bearings 1 E is the trunion of the gimble nut, the gimble nut is threaded
and in the threaded piece works the screwed shaft F. Fitted to the axle C of
the driving wheel H is the sleeved end K' of the framing J J1 J" made of "H
or other suitable section iron. The part J of the framing is bent so that it is
parallel to the tread H of the driving wheel H the part J" is then bent up parallel

page_text: to the part J. To the end J is fitted split sheaves K connected together by bolts
and nuts K
On the upper side of the part J' is fitted the bridge piece N and to the top por-
tion of the bridge piece is fitted the cap M secured to the bridge piece by means
of the bolts Z.
In the cap M is formed a recess L in which works the enlarged end part X of
the unscrewed part of the shaft F this enlarged end of the shaft being free to
revolve. P are the picks secured to the framing J by means of eye bolts T.
The picks P fit into the aperture S of the eye bolts T over the shank of the eye
bolt is fitted a straining plate Q against which straining plate the nuts and
bolts tighten and thus clamp the picks P between edge S¹ of the eye bolt and
the part of the frame J J^J Gis a hand wheel attached to the screwed
shaft and by means of which the frame is lowered and raised as required.
The method of employing this apparatus will now be described.
The engine or other suitable vehicle to which this our apparatus is attached
having been brought to the place which is desired to have picked up. The
frame J JJ is depressed towards the ground by means of the hand wheel G
and the screw F, and as far below the surface as is desired. The vehicle to which
the apparatus herein before described is attached is now set in motion the picks
are thus dragged through the ground and the surface is scarified in the required
manner. It is obvious from the foregoing description that this apparatus can
be attached to one or more of the axles of a self moving or otherwise moved
vehicle, or engine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A combination and arrangement of an apparatus as herein set forth and
described for breaking up macadamised or other hard ground.
2. The attaching of the apparatus as herein set forth and described to the
axles of self-moving and other vehicles and engines.
3. The method of raising and lowering the framework carrying the picks by
means of a screw & screwed trunion nut or their equivalents in the manner as
herein set forth and described.
