WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN HORSE HAY RAKES."
communication from abroad by Edmund D. Reynolds and Oliver B. Reynolds, both
of Brockton, Massachusetts, United States of America.]
[A
The object of this Invention is to provide improved means for raising and locking
the teeth of a horse hay rake, and adjusting the angle of the teeth and the height
of the tooth bar for fastening in the teeth and attaching the driver's seat to the
standard; and the said Invention comprises series of toggle levers combined with a
hand and foot lever, a lever with a spring catch and ratchet to adjust the angle of
the teeth, an adjustable hinge, connecting the tooth bar with the axle, a slotted seat
standard combined with a peculiarly constructed spring attached to the driver's
seat, a novel construction of the wheel, and other improvements herein-after
specified.
The tooth bar of the rake has fastened to it the teeth after passing through a
plate on the rear face of the bar, the said teeth being provided at their upper ends
with suitable openings for their attachment to the bar by screws, bolts, or other
suitable devices.
Extending between the rear portion of the shafts is a cross bar serving to support
a lever, which is provided with a spring catch and ratchet to adjust the angle of
the teeth through the medium of a bar acting on the tooth bar. On the said tooth
bar are secured two ears, between which is pivotted the lower point of a double

page_text: toggle. The inner toggle is formed of links and an extension of a bar. The peak
of the rear toggle is pivotted in a bight made in the end of a bar, and combined
with the toggle is a stop on the same pivot, which keeps the toggle from passing
too far beyond the line of strain. The other end of the last-named bar is pivotted
to a hand lever, which has its lower end attached to the axle. The pivot which
connects the said hand lever and bar is provided with a head, which engages in a
slot in a bar which is pivotted to the foot lever on the cross bar.
The tooth bar is hinged to the axle by an adjustable hinge made as follows:-
Against the axle are two plates having the centre portions of their upper and lower
edges turned over to clasp the corners of the axle and leave projecting lugs at each
corner. Between the aforesaid plates and slotted plates are clasped U shaped rods,
which pass through eyebolts on the tooth bar. The lower end of one leg of each of
these rods is bent at right angles and passes through a hole in the said slotted
plates, which are provided with a series of central holes. There is a plate having
a hole in one end and hooked at the other, and a single bolt passes through this
hooked plate, the slot in the slotted plates, the rods and the other plates into the
axle. Along the rear side of the aforesaid tooth bar is a plate pierced with holes,
through which the teeth pass, the same being bolted to the lower side of the said
bar. This plate acts as a brace for the teeth.
The top of the seat standard is slotted, and a spring is provided with a button,
the shank of which slides into the slot. The lower end of the said spring has a
tongue turned inward to enter the slot and keep it from tilting.
The central portion of the wheel hub is provided with recessed portions for the
reception of the spokes; each recess is provided with a central projection cast in
one piece with the said central portion, thus strengthening the casting. Each of
the spokes is provided with a slot, which when the spokes are inserted in the
mortises of the hub fits snugly over the said projections, and a transverse pin passes
through the spokes and projection to secure the said spokes. Two flanges are
secured upon opposite sides of the said central portion by bolts and nuts in the
usual manner, one flange being in one piece with the axle box, which extends
through the central portion and flange. When the hub is taken apart for packing
the spokes remain in the said central portion, the projections keeping the spokes
from leaving the recesses.

page_text: rods p is bent at right angles and passes through a hole 9 in the said slotted plates
5, 5, said plates 5 being provided with a series of central holes 8, 8.
O is a plate having a hole in one end and hooked at the other end. A single
bolt passes through the hook plate O, the slot in the slotted plates 5, rods p, and
plates 3, and into the axle. The slotted plate provided with the holes permits the
adjustment of the tooth bar to and from the axle and the teeth in relation to the
ground. Along the rear side of the tooth bar is a plate Y pierced with holes y, y,
through which the teeth pass, and the said teeth are bolted in a suitable manner to
the lower side of the bar. This plate acts as a brace for the teeth.
The top of the seat standard P₁ is slotted, and the spring P¹ is provided with a
button, the shank of which slides into the slot. The lower end of the spring P has
a tongue x turned inward to go in the slot and keep it from tilting.
A¹ is the central portion of the bub, provided with the recessed portions 2* for
the reception of the spokes. Each recess is provided with a central projection 3*
cast in one piece with the portion A¹, thus strengthening the casting. Each of the
spokes is provided with a slot 4*, which when the spokes are inserted in the
mortises of the hub fits snugly over the projections 3* and is secured thereto by a
transverse pin 5* passing through holes in the spokes B¹¹ and projection 3*, as
shown in Figure 8*. The two flanges 6* and 7* are secured upon opposite sides of
the portions A¹ by bolts and nuts in the usual manner, the flange 7* being provided
with the axle box extending through the portion A¹ and flange 6*.
When the hub is taken apart for packing the spokes remain in the portion A³,
the projections keeping the said spokes from leaving the recesses.

Having thus fully described, the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it under-
stood that I claim,-
:
First. The toggle raising and lowering device in combination with the foot lever
and connecting rod, as above described.
Second. The adjustable hinge, consisting of the plates, the U shaped rod, and the
hook plate, as above set forth and for the purpose specified.
Third. The cross bar, the lever, and the ratchet, in combination with the bar for
adjusting the angle of the teeth, as and for the purpose set forth.
Fourth. The plate Y pierced with holes in combination with the rake teeth and
the bar D, as and for the purpose set forth.
Fifth. The slotted seat standard in combination with a spring provided with a
bent tongue, as and for the purpose set forth.
Sixth. In a three-part wheel hub the recessed central portion having the pro-
jections 3* cast integral therewith and in combination with the slotted spokes, as
and for the purpose set forth.
Seventh. The combination of parts comprising the wheel hub with the recessed
central portion provided with the perforated projections 3*, the spokes formed with
the central slots and transverse holes, the transverse pins 5*, and the flanges 6*
and 7*, as above set forth and for the purpose specified.
'
In witness whereof, I, the said William Robert Lake, have hereunto set my.
hand and seal, this Fifth day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
