Improvements in or Additions to Slip-ladders.
I, HENRY CRUDGINGTON of 106 Newton Road, Sparkhill, near the City of
Birmingham, Cabinet Maker, 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 relates to appliances known as slip ladders or slopes, for the
transporting or moving of heavy bodies, principally employed in the loading and
unloading of waggons.
In the said appliance, which consists of a long frame, composed primarily of two
sides, connected together by rings or tie bars, no antifriction devices are employed,
and the objects to be transported are moved bodily, or made to slide upon the sides,
hence considerable resistance is offered to the transportation, moving or sliding of
the said bodies.
The object of my invention is a rollered slip ladder, which can be used both as
a rollered inclined plane, over which bodies are slid, or transported by sliding or
moving the same upon the rollers as bearings, or as a ground trolly, upon which
goods packages or the like may be placed, for the transportation of them upon
level or other surfaces.
Figure 1 of the accompanying drawing, represents in perspective a waggon or
like slip ladder, constructed, arranged and provided, according to one form of my
said invention.
Figure 2 represents a longitudinal vertical section of the same, whilst Figure 3
is a cross section, showing one of the rollers, which turn upon the tie rods, in
section.
Figure 4 represents the said slip ladder in use as a ground trolly.
It is understood that when the said slip ladder is in use in connection with
waggons, carts or the like, that the same is placed as an inclined plane from the
rears of them, and may be used, when not in use, to form the end to the said waggon
or cart.
The same letters of reference indicate corresponding parts in Figures 1 to 4.
a, a are slides or side pieces, separated by rollers b, and connected together by
tie rods or rungs c, upon which the said rollers 6 are mounted, and around which
they rotate as bearings.
The peripheries of the rollers upon the top side, or upon one side, project or
stand out beyond the surfaces a², of the said sides a, so that there is a complete
clearance of the frame made thereby, which frame has hook'ended terminations a³.
The extreme ends of the tie rods or rungs take and are secured within the
opposite sides of the frame as represented in the cross section Figure 3.
To convert the slip ladder into a ground trolly, the same has only to be turned
over, when the rollers which extend beyond the frame, come in contact with the
ground, as set forth in Figure 4.
Figure 5 represents a brewers' dray slip-ladder, and Figure 6 represents a cross
section of the same.
In this form the waist 6, of the roller bis reduced, making as it were a
double cone, for the guidance and transporting of barrels, either up or down the
ladder.
By employing rollers with concaved waists, a complete clearance of the sides a,
is made, as the barrels are transported and guided by the rollers. The rollers b
are mounted upon tie rods or rungs c.
Figure 7 represents a still further form of my invention. In this arrangement
narrow rollers or wheels b, are mounted upon end portions of the tie bars or
Prion 77

page_text: rungs c, adjacent to the sides a, and with the peripheries of the said rollers or
wheels standing above the top sides of the frame.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is
First In a slip-ladder, providing the same with rollers or cylinders, disposed
between the sides, and with the peripheries of the said rollers or cylinders, coming
above, or extending beyond the plane of one edge, or both edges or sides, as set
forth.
Secondly In a rollered slip-ladder, mounting the rollers upon the tie bars or
rungs, as set forth in Figures 1, 2, 3 and 4.
Thirdly-In a rollered slip-ladder for barrels or the like, providing the frames
of the same with concave-waisted or double coned rollers, as set forth in Figures 5
and 6.
:
Fourthly In slip-ladders, the construction and arrangement of the parts as
set forth in Figure 7.
