A Novel Construction of Trolly and Gear for Lifting and Shifting
Fowl and like Houses on Poultry and like Farms.
I, THOMAS JAMES FENN, of Palace Plain Works, Norwich, Norfolk, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, a novel construction of trolly or vehicle which
can, after being pushed or run under a fowl or poultry or like house, have certain
appliances raised to lift the house bodily for shifting or for locating it where
desired.
The invention is chiefly intended for use on poultry farms and winged game
breeding establishments where such houses have to be shifted from one part of a
farm to another from various causes for the protection of the birds against
climatic changes and also for keeping the respective breeds apart.
According to my said invention, I construct a skeleton frame and mount it
on low wheels so that it can be pushed or run under a fowl or like house, the
floor of which is built above the level of the ground and has the two side walls
and one end below the floor to rest upon the ground, the other end or it may be
one side having a fall down or hinged flap with battens on for enabling the fowls
to enter and leave and which as a rule is closed up at night as a protection against
foxes and other destructive animals.
The trolly frame has one or more longitudinal rods or shafts with worm gear
where desired, these being arranged for operating pinions set eccentrically on
toothed wheels, a portion of which, say, the peripheries serve as rollers which can
be raised, to come into contact with the under bars of the house, and so lift it
bodily off the ground for moving it to any part of the ground on the bearing
wheels of the trolly. Instead of the circular motioned wheels for lifting purposes,
knuckle links can be operated by the worms, or it may be a threaded rod, which
when rotated by a winch handle in one direction will bring the knuckle joints
closer together and be separated by a reverse motion of the shaft for lowering.
The trolly is movable by hand or animal labour.

This invention has for object, a novel construction of trolly or vehicle which
can after being pushed or run under a fowl, or poultry, or like house, have certain
appliances raised to lift the house bodily for shifting or for locating it where
desired.
The invention is chiefly intended for use on poultry farms and winged game
breeding establishments, where such houses have to be shifted from one part of a
farm to another from various causes, for the protection of the birds against
climatic changes, and also for keeping the respective breeds apart.
According to my said invention, construct a skeleton frame and mount it
on low wheels, so that it can be pushed or run under a fowl or like house, the
floor of which is built above the level of the ground and has the two side walls
and one end below the floor to rest upon the ground, the other end or it may he
one side having a fall down or hinged flap with battens on for enabling the fowls
to enter and leave, and which as a rule is closed up at night as a protection against
foxes and other destructive animals.
The trolly frame has one or more longitudinal rods or shafts with worm gear
where desired, these being arranged for operating pinions set eccentrically on
toothed wheels, a portion of which, say, the peripheries serve as rollers which can
be raised to come into contact with the under bars of the house and so lift it
bodily off the ground for moving it to any part of the ground on the bearing
wheels of the trolly.
Instead of the circular motioned wheels for lifting purposes, knuckle links can
be operated by the worms, or it may be a threaded rod which when rotated by
a winch handle in one direction will bring the knuckle joints closer together and
be separated by a reverse motion of the shaft for lowering.
The trolly is movable by hand, or animal labour..
My invention will be fully understood by reference to the annexed drawings.
Figure 1 plan view of trolly in which eccentric discs are used as the fowl house
lifting appliances under control of worm gear and a winch handle.
Figure 2 similar view of a trolly in which the lifting of a fowl's house is effected
by lever appliances also operated by worm gear and a winch handle.
Figure 3 side or sectional elevation of a trolly with disc eccentrics pushed under
a fowl house.
Figure 4 similar section or elevation of a trolly pushed under a fowl house and
having the lever appliances operable by worm gear and winch handle.
Figure 5 end elevation of a hand trolly under a fowl house.
A, trolly frame. B, handle for moving it, or shafts for an animal can be fitted
to the frame A if so desired. C, winch handle. D, shaft. E, E, worm screws
thereon. F pinions in gear with worms E, these being on cross
shafts G, G, to which are also affixed the eccentric discs H, H, to bear in
direct contact with the bottom or under side of flooring, or against the bottom ties
or joists of a fowl house I, or with a platform J of the trolley itself,, said platform
being held within limits, in any desired manner.
The trolly is shown mounted upon four bearing wheels K, K, K, K, rigidly
arranged but the front wheels may be in connection with a turning appliance, or
a single front castor wheel may be fitted to facilitate its easy movement to any
desired spot. The platform J may be secured to the lifting appliances, as by
the example, Figure 4, where they are toggled by links L, L, to the platform in
opposite directions or fore and aft for ensuring a vertical rise of said platform,
the levers L being on sliding toggle joints M.
Figure 1 shows a single pair of worms E, E, for operating the four eccentric
discs H, H, but at Figures 2 and 4, I employ an intermediate cross shaft N for
giving motion to the second set of levers L, L, thus equalizing the strain and
putting the appliances in better balance than by the method shown by Figure 1
to which such intermediate shaft is also applicable if so desired.

page_text: I have not shown a fowl house lifted clear of the ground but it is readily under-
stood that the height to which it could be lifted is determined by the eccentricity
of the discs, or of the travel of the toggles and links and to enable such a trolly
to be used for the purpose explained I keep the flooring well above the ground by
the side boards and to enable the birds to get in and out when the house is
located, I provide a fall down or fold flap P which serves as a staging during the
daytime and as a shutter at night time to enclose the birds.
The, trolly herein described with a platform is available for the transport of
ordinary articles, goods, or appliances, such as moving straw, fowls food, and the
like about a poultry farm.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
-
1. A trolly with lifting appliances operable as and in the manner described and
substantially as represented on the annexed drawings for the purposes set forth.
2. A trolly frame enclosing and supporting worm gear appliances whereby a
poultry house can be raised and lowered and be retained in either position through
the movement of a hand winch to enable such a house to be lifted and shifted to
any desired part of a farm or place as explained and substantially as shown
whether said trolly has a platform or not as specified.
