DRAFT EQUALIZERS:
This subclass is indented under the class definition. Subject matter wherein the group of subclasses indented
hereunder comprise means for effecting and utilizing the pull of
two or more draft animals, so that the load will be proportioned
to each animal in accordance with unit strength or varying conditions
of pull; also means, where the line of draft relative to the load
is offset, to overcome and prevent so-called "side draft".
(1)
Note. Conventional doubletrees involving only structural
features and attaching means in the line of draft will be found in
this class, subclasses 90+.
Subject matter under "Draft Equalizers" wherein
the draft animals are arranged in a longitudinal aligned relation,
there being any number of animals abreast.
This subclass is indented under subclass 9. Subject matter wherein the pole is offset relative to the
team, i.e., three on one side and one on the other side of the pole.
This subclass is indented under subclass 15. Subject matter wherein an intermediate evener is used to
connect at least two of the draft animals to a main evener or its
equivalent.
This subclass is indented under subclass 18. Subject matter wherein there is a possible adjustment of
position of the singletrees relative to the evener or of the evener
relative to the load to proportion the load according to the strength
or position of each of the draft animals.
This subclass is indented under the class definition. Subject matter comprising devices involving no special harness
modification for quickly detaching draft animals from the vehicle;
usually the driver can operate this disconnection from a position
on the vehicle, as in case of the animal or animals running away.
Harness for Working Animal,
subclass 69 , for devices of like purpose involving harness
modification or special arrangement of harness, with special vehicle
attachments to cooperate therewith.
This subclass is indented under subclass 21. Subject matter wherein upon operation of the detaching device,
brakes are operated to stop the movement of the vehicle.
This subclass is indented under subclass 36. Subject matter wherein the pole body is capable of attachment
to the rest of the pole in a plurality of positions.
This subclass is indented under subclass 36. Subject matter wherein the pole is socketed to a part of
the vehicle and can be slipped into or out of such position.
This subclass is indented under subclass 41. Subject matter wherein the pole has an adjustable rear-end
portion to vary its width to accommodate it to varyingly spaced
axle clips or equivalent axle fastenings.
This subclass is indented under subclass 44. Subject matter wherein thills are so constructed or positioned
relative to a vehicle that the draft animal travels to one side
of the center line of draft.
This subclass is indented under subclass 46. Subject matter wherein the thills may be selectively positioned
to the vehicle, so that the draft animal travels either in the line
of draft or to one side thereof.
This subclass is indented under subclass 50. Subject matter wherein pole tips are provided with means
for preventing accidental removal of conventional neck-yoke centers
from the ends of poles.
(1)
Note. Devices for a similar purpose where the neck-yoke center
is modified will be found in this class, subclasses 51 and 53.
This subclass is indented under the class definition. Subject matter including devices for attaching thills to
a vehicle; usually such connection is made to the axle; one of the
elements of the coupling is formed on the thills.
This subclass is indented under subclass 52. Subject matter including devices adapted to prevent separation
of the thills and vehicle in case of disconnection of the coupling.
This subclass is indented under subclass 52. Subject matter wherein the thills as a whole can be disconnected
from the vehicle by any one of two or more couplings.
This subclass is indented under subclass 52. Subject matter wherein the coupling can be disconnected
by movement of the thills to a special position other than the one
in which the thills are normally placed.
This subclass is indented under subclass 60. Subject matter including devices for attachment to conventional
couplings of the type indicated to prevent rattling of the couplings.
This subclass is indented under subclass 61. Subject matter wherein the antirattling device is formed
as a part of means for securing the pin or bolt in place.
This subclass is indented under subclass 60. Subject matter including special means for holding the pin
or bolt in place other than by conventional nuts, cotter pins, etc.
This subclass is indented under subclass 52. Subject matter wherein one of the elements of the coupling
is a member having opposed lug-engaging or -carrying jaws.
This subclass is indented under subclass 72. Subject matter wherein one of the elements of the coupling
is a separable eye adapted to clamp the transverse member of the "D".
This subclass is indented under subclass 52. Subject matter wherein one of the coupling elements is a
ball and the other is a socket to receive the ball.
This subclass is indented under the class definition. Subject matter including devices for supporting the thills
of the vehicle in any position so that the ends are held above the
ground.
This subclass is indented under subclass 81. Subject matter including devices separate from the vehicle
or thills adapted to engage the thills and some other part of the
vehicle to prop the thills in raised position.
This subclass is indented under the class definition. Subject matter including devices for supporting the pole
of the vehicle in any position so that the end of the pole does
not contact with the ground or the animals are relieved of its weight.
This subclass is indented under the class definition. Subject matter including patents relating to whiffletrees
and to their connections to the pole, thills, or forward part of
a vehicle, unless the invention is such as falls under the definition
of draft equalizers.
This subclass is indented under subclass 90. Subject matter including the connecting means between the
elements of a whiffletree or between the whiffletree and pole, thill,
or forward part of a vehicle.
This subclass is indented under subclass 96. Subject matter wherein the link or clevis is supported resiliently
or consists of resiliently connected parts.
This subclass is indented under subclass 96. Subject matter wherein the link or clevis is so mounted
or constructed as to permit change in the line of draft relative
to the drawn vehicle.
