We, JOHN ROBERT JEFFERIES and FREDERIC WILLIAM GARRARD, both of the
Orwell Works, Ipswich in the County of Suffolk, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object improvements in horse rakes.
The improvements consist in a novel construction, combining adequate strength of
the parts with great lightness, whereby the total weight of the implement is much
reduced; also in novel means for effecting an automatic delivery to be put in action
by the foot of the driver and in conjunction therewith a hand delivery with self-
locking device; and an improved mode of regulating the height of the teeth from the
ground.
The rake teeth are by preference constructed of round steel, and are each attached
to a cast thimble for being strung on to the tooth-bar as usual. The upper ends of
the teeth are bent up at about right angles; and the thimbles are formed with a hole
to receive the bent-up portion of the tooth, and a groove on the underside for the
horizontal portion to lic in; an eye bolt slid over the tooth and passing through the
thimble with a nut at the top holds the tooth firmly in the fore and aft direction and
the bent-up portion prevents twisting. A small flat bar with holes in proper number
and distance apart placed under the nuts of the eyebolts affords a ready means of
coupling the teeth in pairs or groups as desired.
The frame is composed of a plain round bar of iron or steel on to which are slid two
castings which are clamped by a set screw at about two feet apart in the middle of
the length of the bar on the ends of the bar are placed cast caps, which are held
on and drawn towards each other by a light tie rod which takes a bearing against.
the intermediate castings, these having a notch for the tie rod to lie in. The tie rod
being placed vertically beneath the round bar, the strength in the vertical direction is
provided for. The end caps and intermediate castings have flanges to which are
attached flat bars projecting horizontally towards the front; the bars are brought
together, two and two, so as to form two triangles upon the round bar as a base;
the horse shafts are attached to the bars near the apexes of the triangles and the
footboard forms a strut between the same; thus a very strong horizontal truss of
eli

attachment of the bars for supporting the clearing frame towards the rear.
The end caps on the round bar are formed at the outer ends to receive other castings
to turn thereon; these latter have flanges with a slot hole, through which a bolt or
stud in the end caps passes, and may thus be clamped by a nut in any position within
the range of the slot. These outer castings contain the axle bearings for the road
wheels at a suitable distance from the centre of the frame bar; the axles of the road-
wheels may thus be set up and down for regulating the height of the rake teeth from
the ground.
The rocking frame consists of three castings which turn freely on the frame bar; to
the forward end of these castings is attached the lifting bar which is a flat bar extending
the whole width of the set of teeth; the ends of this bar are bent towards the front and
upwards to form the end bearings of the tooth bar upon which the rake teeth are
strung; three intermediate supports bolted to the lifting bar give sufficient rigidity
to the tooth bar. The centre of the tooth bar is slightly above the centre of the frame
bar, and the rake teeth are curved so as to rest upon the lifting bar and pass clear
underneath the truss rod, by which latter the rise of the teeth is limited.
The hand delivery is effected by a bent lever which is centred upon the footboard
and has a rule joint connection with a connecting rod attached to the central casting
of the rocking frame; the connecting rod is extended somewhat beyond the point of
connection with the rocking frame casting, and a spiral spring at the extremity
attached to an arm on the casting sorves to hold the rule joint steady against tremor
and prevents accidental unlocking of the rocking frame.
For the automatic delivery a spindle is mounted in bearings formed upon the two
central castings on the frame bar; this spindle is connected with either or both of the
road wheel axles (if connected with both a ratchet connection is used so that either
wheel may stand still in turning sharp corners; or the ordinary differential coupling
may be employed for the purpose); a second spindle is mounted in bearings upon the
shaft bars, parallel therewith, and a pair of spur wheels connects the two; the spur
wheel on the second spindle has a ratchet wheel attached or cast in one with it; this
ratchet wheel thus turns continuously with either of the road wheels. Upon the
spindle of the ratchet wheel is loosely mounted a lever which carries a pawl in a
position to engage the ratchet-wheel, and the pawl has a lateral projection which
.forms a treadle for the foot of the driver; a spiral spring attached to the back of the
pawl and a lug on the lever holds the pawl clear of the ratchet wheel. The upper end

depresses the treadle the pawl engages a tooth of the ratchet-wheel, the lever is then
carried round with the wheel, and its movement being conveyed to the hand-lever, the
unlocking and turning of the rocking frame, for raising the teeth, is effected in the same
manner as by the hand-lever alone. A fixed cam raises the pawl out of the tooth of
the ratchet wheel at the proper point, and the rake teeth fall by their own weight;
the spiral spring on the pawl restores the position of the treadle.
A seat for the driver is supported by a bent bar attached at the front to the foot-
board, and at the back to one of the castings on the frame bar.

page_text: We, JOHN ROBERT JEFFERIES and FREDERIC WILLIAM GARRARD, both of the
Orwell Works Ipswich in the County of Suffolk, Engineers, 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:-
This invention has for its object improvements in horse rakes.
The improvements consist in a novel construction, combining adequate strength of

locking device; and an improved mode of regulating the height of the teeth from the
ground.
The rake teeth are by preference constructed of round steel, and are each attached
to a cast thimble for being strung on to the toothbar as usual. The upper ends of the
teeth are bent up at about right angles, and the thimbles are formed with a hole to
receive the bent-up portion of the tooth, and a groove on the underside for the

the bent-up portion prevents twisting. A small flat bar with holes in proper number
and distance apart placed under the nuts of the eyebolts affords a ready means of
coupling the teeth in pairs or groups as desired.
The frame is composed of a plain round bar of iron or steel on to which are slid two
castings which are clamped by a setscrew at about two feet apart in the middle of the
length of the bar; on the ends of the bar are placed cast caps, which are held on and
drawn towards each other by a light tie rod which takes a bearing against the inter-
mediate castings, these having a notch for the tie rod to lie in. The tie rod being
placed vertically beneath the round bar, the strength in the vertical direction is
provided for. The end caps and intermediate castings have flanges to which are
attached flat bars projecting horizontally towards the front; the bars are brought
together, two and two, so as to form two triangles upon the round bar as a base; the
horse shafts are attached to the bars near the apexes of the triangles and the foot-
board forms a strut between the same; thus a very strong horizontal truss of the
round bar is secured. The castings aforesaid have likewise Hanges for the attachment
of the bars for supporting the clearing frame towards the roar.
The end caps on the round bar are formed at the outer ends to receive other castings
to turn thereon; these latter have flanges with a slot hole, through which a bolt or
stud in the end caps passes, and may thus be clamped by a nut in any position within
the range of the slot. These outer castings contain the axle bearings for the road

page_text: wheels at a suitable distance from the centre of the frame bar; the axles of the road-
wheels may thus be set up and down for regulating the height of the rake teeth from
the ground.
The rocking frame consists of three castings which turn freely on the frame bar:
to the forward end of these castings is attached the lifting bar which is a flat bar
extending the whole width of the set of teeth; the ends of this bar are bent towards
the front and upwards to form the end bearings of the tooth bar upon which the rake
teeth are strung; three intermediate supports bolted to the lifting bar give sufficient
rigidity to the tooth bar. The centre of the tooth bar is slightly above the centre of
the frame bar, and the rake teeth are curved so as to rest upon the lifting bar and
pass clear underneath the truss rod, by which latter the rise of the teeth is limited.
The hand delivery is effected by a bent lever which is centred upon the footboard
and has a rule-joint connection with a connecting rod attached to the central casting
of the rocking frame; the connecting rod is extended somewhat beyond the point
of connection with the rocking frame casting, and a spiral spring at the extremity
attached to an arm on the casting serves to hold the rule-joint steady against tremor
and prevents accidental unlocking of the rocking frame.
For the automatic delivery a spindle is mounted in bearings formed upon the two
central castings on the frame bar; this spindle is connected with either or both of
the road wheel axles (if connected with both a ratchet connection is used, so that either
wheel may stand still in turning sharp corners; or the ordinary differential coupling
may be employed for the purpose); a second spindle is mounted in bearings upon the
shaft bars, parallel therewith, and a pair of spur wheels connects the two the spur
wheel on the second spindle has a ratchet wheel attached or cast' in one with it; this
ratchet wheel thus turns continuously with cither of the road wheels. Upon the
spindle of the ratchet wheel is loosely mounted a lever which carries a pawl in a
position to engage the ratchet wheel, and the pawl has a lateral projection which
forms a treadle for the foot of the driver; a spiral spring attached to the back of the
pawl and a lug on the lever holds the pawl clear of the ratchet wheel. The upper
end of the lever is attached by a connecting rod to the hand lever. When the driver
depresses the treadle the pawl engages a tooth of the ratchet wheel, the lever is then
carried round with the wheel, and its movement being conveyed to the hand lever,
the unlocking and turning of the rocking frame, for raising the teeth, is effected in
the same manner as by the hand lever alone. A fixed cam raises the pawl out of
the tooth of the ratchet wheel at the proper point, and the rake teeth fall by their own
weight; the spiral spring on the pawl restores the position of the treadle.
A sent for the driver is supported by a bent bar attached at the front to the foot
board, and at the back to one of the castings on the frame bar.
And in order that our invention may be better understood we will now proceed to
