I PHILIP UNWIN ASKHAM of the Yorkshire Steel Works Napier Street Sheffield
in tho County of York Steel Manufacturer do hereby declare the nature of my 'said
"Invention for AN IMPROVED TRUCK FOR LIFTING AND CARRYING HEAVY WEIGHTS
AND LONG ARTICLES to be as follows:
30ind out bonus violaci
The apparatus or appliance consists of a pair of wheels upon which is mounted,
or to the axles of which is fixed, a bow shaped frame so formed as to leave a clear
way under the frame and between the wheels for the articles to be lifted and
carried.

On the said frame, or on the short, end offa lever of which the frame is the
fulcrum, is mounted a pair of tongs, dogs, clips, or chains, either fixed or capable
'of being actuated by a long lever or handle fixed or fitted to the bow shaped frame.
Between the frame and the end of the said lever, or the handle, is a holder, dog,
clip, or chain, sliding or otherwise; for, supporting or carrying one end, or tho
greater part, of the article to be lifted and carried.
In using the apparatus the end of the lever or handle fixed or fitted to the frame
is elevated so as to depress the tongs, dogs, clips, or chain, to grip, or be secured to
the article at the front end, and after the lever has been depressed, the article to be
lifted if a long one-is secured to the holder on the lever or handle at or towards
the back end thereof and on bringing the lever or handle to a horizontal position or
thereabouts the article is, lifted clear of the ground to a position in which it can be

page_text: hook, n, is fixed to the frame, c, to which may be attached a hauling rope, or chain,
a hook, p, is similarly fixed, and may be used either for haulage or suspending
purposes, q, q; are two flat springs, which cause the clips, e, to open outwardly
when the long axis of the can, g, is turned vertically (a position the reverse of that
shewn in Figure 2), several holes marked, r, may be provided in the clips, e, by
means of which the arms of the same may be lengthened or shortened as required.
In Figures, 4, 5, 6, and 7, which represent enlarged views of the expanding,
elliptical cam, g, is the body of the cam; g', the flange of the same; s, s, are the
expanding segments of the cam which can be adjusted inwards, or outwards, from
the body of the cam, and fixed in position by the set screws, t, t, by this device,
the action of the cam may be increased and the range of the arms of the clip, in a
corresponding degree extended. The centro hole, u, in the body of the cam, g,
receives the square end of the hollow spindle, rod, or bolt, h, which is turned by the
handle, i, at the end of the shaft or lever, d.
When in use the action of the improved truck and its several parts, is as
follows; after the truck has been wheeled to, over, or astride of the article to be
lifted and moved, care should be taken that the centre of suspension (the clips) is
somewhere near the centre of gravity of the article to be so lifted and moved, this
may easily be ascertained by making a trial lift or lifts; by preference the point at
which the article is suspended should be so arranged that the portion of the article
to the front of the truck, should be slightly heavier than that portion which is at
the rear, the reason for this will be presently shewn.
The handle, i, at the end of the shaft or lever of the truck, is turned from the
horizontal position (A. B.) to a vertical position (CD) as shewn in the drawing,
Figure, 2, by this movement the elliptical cam, g, is turned with its short axis,
between the upper and shorter arms, of the clip, e, which close inwardly, towards
the cam; by the action of the springs, q, q; which at the same time cause the lower
and longer arms of the clip, e, to open outwardly, towards the wheels of the truck.
(This last named movement may be made before the truck is brought into position
as previously described) The shaft or lever, d, is then elevated at the handle end
which causes the extended, or gaping clips, to be correspondingly depressed, so that
when they are in a suitable position for clipping, or gripping the article to be
lifted. The handle, i, is turned back to horizontal position, (A, B,) when the long
axis of the cam is again turned into its horizontal position, between the upper and
shorter arms of the clips, c, which are thereby opened outwardly, causing the lower
and longer arms of the clips, e, to close inwardly, and clip or grip the article to be
lifted; The handle end of the shaft or lever, d, is then lowered to its normal,
(horizontal), position when the article held by the clip is raised clear from the
ground and may be moved as desired. If the article so lifted be a long one and
care has been taken that its heaviest end is to the fore part of the point of
suspension, then the rear end will incline upwards and will come in contact with
the holder or clutch f, which will have previously been placed in a convenient
position on the shaft, or lever, d, by this method the necessity of any other means
of suspension beyond that afforded by the clip e, would be dispensed with.
The Improved truck as herein described may be used for a great variety of
purposes, but amongst those for which it is specially well adapted, may be named,
the lifting and carrying of railway, and tram rails, points and crossings; pipes,
bars, axles, rolls, guns, shot and Shell, and it may also be employed for lifting and
carrying steel crucible pots, into and out of the Melting Furnaces.
The Improved truck may be fitted with duplicate sets of clips specially adapted
by the form and disposition of the lower arms, for taking hold of and lifting a
great variety of special articles for example The clips used for railway work
would have a different form to clips used for lifting shot and so forth.
A hoop, loop, catch or chain may be used on the lower arms of the clip, e, to
secure them together when the weight is suspended, and to prevent them being
strained or sprung open.

page_text: Duplicate Cams may also be supplied with the truck when required to have a
greater range of gripping power than can be obtained by the expanding elliptical
cam already described..
Wheels of various diameters may also be used with the same truck.
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
(1
(1.) The construction of an improved Truck for lifting and carrying heavy
weights and long articles, by means of adjustable automatic appliances fitted to
the said truck, for taking hold of, and raising from the ground, such heavy weights
and long articles, and holding or suspending the same, clear of the ground, whilst
being so moved or carried by the said Truck.
(2) The particular arrangement of mechanism of such Automatic appliances,
consisting of the tong shaped clips, the expanding elliptical cam, and the hollow
spindle which actuates the sanie, by the handle of the truck which is affixed to the
said spindle.
(3) The application of an expanding elliptical cam, with adjustable segments by
which the action of the cam may be increased and the range of the arms of the
tong shaped clips extended.
(4) The application in conjunction with the same truck and automatic appliances
of duplicate long shaped clips having varying lengths and form particularly at the
lower ends of the Arins of the same, so as to adapt the truck and appliances to a
variety of similar uses.
(5) The combination of the foregoing appliances, devices and mechanism-with-
-the-form and construction of truck herein described and illustrated by the
accompanying drawings Figures, 1. 2. 3. 4. 5. 6. and 7.
