PRUVIDIUNAL ŊFEULTIVATION,
Improvements in Hand Trucks for Railway Luggage and other
Purposes,
I, HARRY CROWTHER SLINGSBY, of 13, Bath Street, Leeds Road, in the City of
Bradford, Wholesale Bottler, do hereby declare the nature of this invention
to be as follows:-
This invention more particularly relates to improvements in that type of hand
trucks for which Letters Patent No. 14,347 were granted to me on the 26th July
1894.
I lock the two centre wheels by sliding bolts or rods mounted in suitable guides
and engaging holes or their equivalent in the wheels. These locking bolts are fixed
to opposite ends of an approximately vertical lever rigidly secured to a rod or bar
mounted in suitable bearings and extending to each end of the truck or to a
suitable position beneath handle. The ends of said rod or bar are cranked or
suitably bent and a vertical or suitably inclined rod is coupled to each cranked
end. The vertical rods are supported in suitable guides or slides formed in or
projecting from any convenient part and extend up close to the underside of the
handles. A looped handle or finger piece is provided at the top of each vertical
rod located in such a position that it can be laid hold of and lifted up to the handle
when the latter is laid hold of to manipulate the truck and the parts are so
constructed and arranged that the act of lifting the vertical rods in this way
slightly turns the cranked lever rod below and thereby withdraws the bolts or
their equivalent locking the wheels.
Dated this 9th day of January 1899.
Improvements in Hand Trucks for Railway Luggage and other
Purposes.
I, HARRY CROWTHER SLINGSBY, of 13, Bath Street, Leeds Road, in the City of
Bradford, Wholesale Bottler, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention more particularly relates to improvements in that type of hand
trucks for which Letters Patent No. 14,347 were granted to me on the 26th July
1894, and its object is to provide efficient means for automatically locking a
wheel or wheels of this type of truck.

page_text: To fully describe my invention reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar figures of
reference indicate corresponding parts in each of the views.
Figure 1, represents a side elevation of a truck fitted with my improvements.
Figure 2, is a view of the underside of the same.
Figure 3, is an end view of Figure 1.
I lock the two centre wheels 2, 2 by sliding bolts 3 and 4 the ends of which
engage one of the holes 5 in such wheels. The bolt 3 slides through a guide eye
in a downwards extension 6 of the bearing bracket 7 on that side, and the
bolt 4 passes through a guide hole made in the side beam or frame 9. These
locking bolts are pivoted to opposite ends of the approximately vertical lever 10
rigidly secured to the rod or bar 12 mounted in bearings 13, 13 secured to the
underside of the bottom 14 of the truck. The ends of the rod beyond the
bearings 13 are cranked upwards at 15 to clear the sliding wheels 16, 16 at each
end and the extremities 17 are bent over towards one side and engage eyes 18
formed in the lower ends of the rods 20 one of which is provided at each end.
The rods 20 pass through guide eyes in the bottom 14 of the truck as well
as through guide eyes in the brackets 25 fixed to the end frames 26 of the
truck. A looped handle 28 is formed at the top of each rod 20 in such a position
that it can be laid hold of and lifted up to the handle 30, when
the latter is laid hold of to manipulate the truck, whereby withdrawing the
bolts from the wheels 2 and consequently unlocking them. When the handle 28
is released the weight of the parts tends to return the bolts to the position
shown and re-lock the wheels as soon as any of the holes 5 come opposite the ends
of the bolts.
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:―
"
The combination with the locking bolts 3 and 4 engaging the holes or their
equivalent in the wheels, of the lever 10, the bar 12 and the rods 20 all arranged
and operating substantially as herein shown and described and illustrated in the
accompanying drawings.
