Improvements in Hand-trucks.
I, ROBERT HAIGH RAYNER, of 36, Bayswater Road, in the City of Leeds, County
of York, Mechanical Engineer, 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;
-
My present invention relates to certain improvements in hand-trucks, the objects
being (one) to so arrange the bearings for the front or end axles that axles of
polygonal or oval or elliptical form in cross section may be used without it being
required to reduce, round, or turn the ends of same in order to enable them to
revolve in the bearings, by which means such axles may be uniform in cross
section their full lengths.
(Second) to so arrange the bearings for the centre axle of my improved truck
that the wheels may be secured to a square polygonal, oval or elliptical cross
sectional shaft of uniform section its full length and the same may also freely
revolve in said bearings.
(Third) to so construct the end rails or uprights of my improved truck that
single bend only is formed at the top thereof so considerably economising its
manufacture, and to so bend the said uprights that novel suitable and con-
venient handles are formed therein thus dispensing with the usually attached
cross handles, and also to further improve the construction of said uprights or
end rails that they may be more firmly secured to the bottom and sole of truck
than is possible when using uprights as hitherto constructed and by which
means greater strength is secured for the frame part of my improved truck without
additional cost.
To attain these objects therefore I employ the various improvements sub-
stantially as herein described and set forth by the aid of the accompanying
drawings in which:
Fig. 1 is an isometric perspective elevation of my improved truck.
Fig. 2 is a sectional elevation along the axis of front or end axle and wheel.
Fig. 3 is a cross sectional elevation on line a a and Fig. 4 a plan of bearings
shown at said Fig. 2.
Figs. 5 to 12 are cross sections of axles of various forms which may be con-
veniently and economically used in combination with the said bearings.
Fig. 13 is a cross section of improved boss for front or end wheel working on
a square sectional axle.
Fig. 14 is a sectional elevation along the axis of middle axle of my improved
truck with wheel and bearings.
Fig. 15 is a cross section on line b b and Fig. 16 a cross section on line ce
of said Fig. 14, and Fig. 17 is a plan of bearing shown to left in Fig. 14.
Fig. 18 is a sectional elevation and
Fig. 19 an end view of foot of my improved upright or end rail.
Similar letters of reference denote corresponding parts in each view:
In order to attain object one aforesaid I will refer to Figs. 2 to 12 in which
D represents the axle which may be in either or any of the forms shown, and

page_text: of equal section for its full length. E represents my improved block or carriage
which is formed with a pocket or recess e circular in form, and within bears a
circular bush or carrier H having a recess, indent or pocket corresponding to
the cross sectional shape of the axle D. The wheel W is first placed on the shaft 1)
whereon it is free to move laterally in the usual way and then the ends of said
shaft are placed within the bushes H and the bearings are secured to the soles S of
truck (see Fig. 1) when the axle may freely revolve with the wheel W as will be
obvious. Referring to Fig. 13 the boss w¹ of front or end wheel may have
stripping pieces w² to bear on the shaft D so as to reduce friction during the lateral
movements of the wheel W.
In order to attain object two aforesaid I will refer to Figs. 14 to 17 in which
J represents a carriage arranged in two lateral halves, each half having a circular
recess or pocket therein which are secured together by a staple j', and to the bottom
of truck subsequent to placing therein a block, bush or disc K which has a circular
outer periphery to correspond with said recesses and a hole through its centre
corresponding with cross sectional shape of axle 1), or instead of forming the carriage
in two lateral halves I may divide it vertically as shown to the right in Fig. 14
and in cross section at Fig. 15 where L represents the carriage having a cap
each having a semicircular recess for the reception of the disc or bush K. The
wheels Ware fitted to the shaft D on the outer sides of the bearings and they are
free to revolve together as will be obvious.
In order to attain object three aforesaid I form malleable feet M as shown at
Figs. 1, 18 and 19 which are preferably of web section and have flanges m¹ and m²
extending respectively down the ends and on the top of floor of truck and are
secured by bolts or screws as shown. The top parts m³ of said malleable feet are
extended in the form of vertical pins and either threaded or corrugated, and they
receive the ends of the wrought iron or other tubes M which form the remainder
of the end rails or uprights. These end rails bend to one complete curve or
sweep at the top (as shown at Fig. 1) so saving the cost of the two angular bends
hitherto generally employed and I likewise bend vertical handles m in said
uprights so saving the cost of two separate attachable handles.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed. I declare that what I
claim is
1. As an improvement in hand-trucks the combination with a front or end axle,
of polygonal or oval form in cross section and of uniform section its full length,
of a carrier carriage or box having a circular recess with circular bush free to
revolve therein and carrying the end of said shaft substantially as described.
(2). As an improvement in hand-trucks the combination with a middle axle
square polygonal or oval in cross section and of equal section its full length of
a carriage or box divided either vertically or laterally and having recesses for the
reception of a circular bush free to revolve therein and which bush carries said shaft
through centre of same substantially as described.
(3). As improvements in hand-trucks the combination of malleable feet and
wrought iron tubing secured thereto the latter having one complete bend at its
apex and bent out vertical handles and all secured to the trucks substantially in
the manner described and illustrated.
