AN IMPROVED TRUCK OR TROLLEY FOR MOVING HEAVY MATERIALS
Year: 1884

page_text: I GREENWOOD ASHWORTH Mechanic 26 Bengall Street Keighley Yorkshire do
hereby declare the nature of my invention for AN IMPROVED TRUCK OR TROLLEY
FOR MOVING HEAVY MATERIALS to be as follows:-
It is a small machine that can be used for moving heavy materials of any
dimensions.
It is made in wrought & cast iron or any suitable material in which it can be
made.
It is composed of two separate parts connected by a chain (Y), one end of which
is fastened to a roller (b) in the fore part, & passes through a guide (a) on to the
roller (b) so as to keep the fore part straight with the back. The reverse action of
this roller is checked, by a small catch wheel (U), and the roller is moved by hand
with a small wheel at the side (Z) so as to separate each part any distance.
The fore part (Fig 1 2 & 3) is supported on three wheels (K-K, D), the move-
ment of which is either to balf right or half left, according to the action of the
handle (C) at the front, which is attached to the fore wheel (D).
To this fore wheel is fastened a semicular plate (E), which works along with it
in the centre of which is grooved a semicular space (F), in which works a small
pulley (G), the space being about " larger than the diameter of the pulley.
The pulley works on a pivot (or stud) (ƒ) which is connected to a crank (I)
which passes to the back, being then attached to the back wheels (K-K) thus
directing the back wheels in the same course as the front wheel (D).
The crank (I) is connected & works on a pivot at each back wheel.
The back wheels are bolted to an inch plate (W), on the top of which is fastened
the casting (L) this casting forms the body of the truck. To (L) is fastened a
plate (M) covering the whole surface at the top.
Under this plate (M) are small hooks (X-X) to which can be fastened a rope
or chain to hold fast any material that is being moved. In the said plate (M) are
two small holes (N-N) in which to insert bolts to fasten planks etc. to increase
temporarily the width of the truck, this completes description of fore part.
The back part Figs 4, 5 & 6. is of the same height & width as the fore part but
narrower & is supported on three wheels (0-0-0) similar to the wheels of the fore
part, but which are fixed. These wheels are fastened to an inch plate (P), on the
top of which is fastened the casting (R) or body of the truck. Two holes (S-S)

page_text: are bored in this casting through which the chain passes, after which if required
the chain can be utilized by carrying it forward & around the material that is
being carried thus forming a self grip. On the top of the casting (R) is a similar
plate (V) to fore part. The plates V & E at the top of back & fore part of truck
are so shaped that when drawn together they form one combined truck, But when
extended the material that is being moved acts as the combining power to each
part of the truck. Thus causing the wheels of (fig. 4, 5, 6) to take the same course
as those of Fig 1, 2 & 3.
Fig 7 Shows the plan of the crank (I), the semicircular-plate (E), the space (F);
(the handle (c) being straight out) & parts of front wheel marked as in Fig. 1, (d)
& (e) with studd passing through' centre of wheel; also where crank is attached
with a nivot to book urhoala .
right or left.
Fig. 9. Elevation of a studd (f) used in working the three wheels in fore part
of truck, also used to act as the pivot for crank at the back wheels & pivot for the
pulley to work on in the semicircular space.
Fig 8 Shows (an enlarged section of the semicircular plate, showing how the
crank (I) is attached to the plate (E)) & also the pulley (c) working on the studd.
(N.B) It can be made to any strength or size as cases require.

page_text: When any heavy material about to be moved is placed on both parts of truck
it must essentially follow that the back part of truck must follow the fore part; as
the material being moved acts as the combining power to both parts of truck
because it is bound to the truck by chain (C).
It may be made of any size or strength and of any suitable material.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
I I claim as the principal feature of my invention the manner in which the three
front wheels (B, B, & B3) work in one direction, according to the action of the
handle, which is either to half right or half left.
II The manner in which the three front wheels direct the course of back
part (A) when any material being moved forms the body.
III Making the truck in two separate parts so that it can be made to carry any
length of material, and when the truck is loaded, the chain from the front part
passes along to back part, and can secure the material being moved in the manner
of a self grip, as it is checked from slipping by the catch wheel.
IV The manner in which the three wheels in fore part are attached to body.
V The combination of the semi circular plate I with the crank N substantially
-as-and-for-the-purpose described.
VI The manner in which the crank moves the back wheels, (B,-&-Bg)-in-the
same direction as the front wheel (B.).
VII The use of either one or two pulleys in connection with the semi circular
plate as described.
VIII The construction, form and design of complete truck throughout.
