page_text: Improvements in or relating to Spring Tyres and Rims.
I, HENRY DE LASPÉE, 153, Broomwood Road, Wandsworth, S.W., Manufacturer,
do hereby declare the nature of this invention to be as follows:-
1) The application of a tranans tyre between the tyre proper and the fillet; or
applying the same to wheels where these parts are in one; such as trams, traction
and railway wheels. (By the word "tranans" I attempt to convey, in a short and
concise manner; my invention of an additional tyre to wheels; which I place
between the tyre proper and the fillet: The theory, which I here propound, is
that of the flanged wheel on the railway: I make use of the fillet or the tyre for
this purpose.
"
My idea, in providing a tranans-tyre," is; to obtain the same smooth running,
of the railway, on an unprepared uneven surface or road. For this purpose I
provide either the fillet or the tyre with a groove. In the case of the tyre I
place it at the back and fix the tranans tyre to the outer surface of the fillet.
If I use the fillet for the groove I provide the tyre-proper with a
"
"
tranans-
tyre." By this means the "tranans-tyre" has a smooth and even surface in which
to travel. So that smooth travelling, over rough and irregular surfaces, may be
compensated I provide and fix or adjust, between the tyre-proper and the fillet,
on the outer edges, on both sides, springs shaped so as to have free movement
vertically and horizontally, but rigid laterally, when compressed into their places.
By this means the tranans-tyre travels in the grooves as the railway wheel
travels between. the rails; with equal smoothness. As the grooves shift with the
tranans-tyre," when in motion, without the advantage of a prepared road I
make use of the springs to regulate and adjust or compensate irregularities. By
this means I prevent vibration or bumping, and regulate the resilience. The
springs, being in tension readily give against any irregularity, according to its
magnitude; adjusting and compensating the variations and maintaining equili-
brium.

2) The application of a double set of single, or continuous springs, of various
shapes, to both sides, between the tyre proper and fillet.
3) In the application of additional, or more tyres or fillets for the purpose of
mounting spring tyres.
4) The construction and application of various shapes and forms, patterns and
designs of springs, in single sets or in continuous coils; filigrees; alternate
or pinnate bands; that will act vertically, horizontally and perpendicularly by
pressure, tension and expansion.
5) In the construction and application of various forms and shapes of tyres
and fillets, rims and tranans tyres, tranans guides: diaphragms and stays.
6) In the application of a diaphragm to the outer tyre, fillet, and rim.
7) In the construction and application of grooves, in the tyres and fillets, to
regulate and keep in place the various forms of springs applied.
8) In the construction and application of drilled pierced, punched or perforated,

page_text: round, square or oblong holes through the beadings, or other parts, of the tyres
fillets and rims, to hold and secure springs.
9) In the construction and application of concave channels, side guides or
grooves to regulate the travelling of the tranans tyre.
10) In the application of pressure to the springs on fixing them into place so
that they expand in equilibrium to the additional pressure or expansion when
in action.
11.) In the construction and application of a solid, or elastic, shield or cover
to the outer tyre; the tranans tyre; or concave channel, side guides, or grooves,
of metal, organic substances, their possible amalgams or compounds to silence or
ease the metal workings.
12.) The construction and application of a ribbed surface, or excoriated surface,
to the metal, gutta percha, celluloid or their compounds, of the outer tyre, to
prevent slipping.
13.) In the construction and application of a guard, screne, or cover, to both
sides, between the outer tyre and the inner fillet of the wheel to protect the springs
and interior against wet, damp, mud, or dust.
For instance
1.) I use steel, iron, copper, brass, aluminium or any other metal or mixture
of metals, wood paper pulb, celluloid, rubber guttapercha, or their compounds,
cork or composition containing cork, or all or any of them in combination or com-
pounded as may suit my purpose in constructing tyres, fillets, rims, inner or
outer tyres tranans tyres, tranans tyre guards or ways, dirt excluders and springs.
I construct the fillet in such a way that the surface of the circumferance,
facing the inner side of the tyre-proper, is concave to the extent of about the third
of a circle the center of which is further grooved, so that the spoke-ends are
sunk away, and covered. At both sides of the concavity I bring out a ledge,
turning the material at right angles towards the tyre, bordering the surface at
the angle with a ridge, leaving a narrow surface, I lap over the material, on that
side, facing the tyre, and carry it back innwards in line with the circle of the
concavity where I join it to the main structure, by braizing, if necessary. Thus
I obtain a hollow, nearly oblong beading on both sides of the fillet.
I now construct an inner, or tranans-tyre-guard or runner which I shape in
reverse of the fillet.
In the surface of the beadings, facing each other, of both these structures, I
punch, pierce or stamp-out square, oval or oblong holes, at suitable distances from
cach other, in such a way that the material, if fractious, parts divides or separates
and rolls back upon itself leaving a smooth surface to the edges.
I now construct the tyre-proper which I hollow out by bending the material
to about a third of a circle, wide enough to cover the beadings of the tranans tyre
guard, or nearly so, I turn under the edges, at right angles, to form a band on
both sides to fit close over or I may leave space between for a wad.
I cover, this tyre proper, with any of the organic materials, suitable, which
I may bring round, between the spaces, of the tyre proper and tranans tyre guard.
Exegency of manufacture may require that the concavity of the tranans tyre
guard be shallower than that of the fillet; if so, the beadings on the inner side
may have to be raised.
I construct the tranans tyre; which may be hollow or solid, and of organic or
inorganic material, and round, and fix it into the space of the concavity in the
fillet.
I now make the springs; which may be in one length or in divisions. The
material may be round, square or flat. I shape or fashion the continuous spring
in zig zag the apices of which I round nearly into circles. Those in sections have
_half circles continued out of each point with the circle at the apex as in the
continuous spring. I may also single springs shaped in parallel lines with both
ends circled where the ends may meet or be joined by braizing or otherwise.
I set up the wheel by putting the tranans tyre guard over the fillet and filling

page_text: up the space between, on both sides, of the plain, in radius, with the springs,
the circle ends of which, I squeez or press, alternately, top and bottom, through
the sockets, which secure them by their necks.
I cover the space, on both sides, bounded by the ridges, in fillet and tranans-
tyre-guard beadings, with a shield in two parts; that which is fitted to the fillet
being narrower and sheething over that which is fitted to the tranans tyre guard I
join them together with a loose or elastic joint.
The object I have in adding a tranans tyre is to save the springs from strain
which I intend to act only on travelling over uneven or rough surfaces or obstacles
where they produce only a slight resilience; as it travels in the tranans tyre
guard on an even and smooth surface.
Again
2) I construct a fillet precisely similar to that in No. 1, but, in addition, I
corrugate the inner surface of the lower ledge of the beadings.
I construct a hollow tyre proper rounding the outer surface which I ridge,
or rib, or otherwise excoriate to prevent slipping I construct the beadings round
on the inner side under shelter of the tyre which are in all else a reverse of the
fillet beadings; save that the inner sides shape in circle with back of the tyre to
form a channel for the tranans tyre; which, in this case, travels on the inner
surface of the tyre the beadings acting as guides.
The

material may be round, square or flat. I shape or fashion the continuous spring
Those in sections
in zigzag, the apices of which I round nearly into circles.
continue in half circles out of each end with nearly a circle forming the apex,
as in the continuous spring. I may also use single springs shaped in parallel lines
of material with both ends circled; where both the ends meet they may be braized
or otherwise joined or left open.
I construct the tranans-tyre hollow or solid and of organic or inorganic material,
and round, and fix it into the space of the concavity in the fillet.
In the surface of the beadings, facing each other, of both these structures, I
punch, pierce or stamp-out square, oval or oblong holes at suitable distances from
each other, in such a way that the material parts, divides or separates and rolls
back upon itself leaving a smooth surface to the edges.
I cover the space on both sides, bounded by the ridges, in fillet and tyre beadings,
with a shield or cover; which may be in two parts; that in the fillet sheething over
that fitted to the tyre and united by an elastic or flexible joint.
I set up the wheel by putting the circle ends of the springs through the holes
or sockets in the beadings, top and bottom, of the fillet and tyre, on both sides.
The springs being compressed on fixing so that they keep the structure in tension;
by being so compressed they are able to follow the action by compensating
harmoniously all pressures.
I further illustrate
2*) In this case I use a similarly constructed fillet as No. 1, save that it is
narrower and that the beadings come closer together in which I drill or pierce, at
convenient distances apart, round or oval holes, in the sides, or plain, facing
outwards, at right angles; with, also, no space for tranans tyre.
The tyre I construct hollow, as before; but with a deeper ledge to bring the
beadings, which are set further back, level with those in the fillet I add a
diaphragm or stay in the hollow round the center of the back for additional
strength to the stability of the circle I make this diaphragm by lapping in material
at the center of the outer circumference, joined at the angles, which may be
braized or otherwise fastened together, broadening out into a hollow, in section,
pear shaped structure which may reach between the inner edges of the beadings
which it may support. I pierce the holes in the same, plain, of the beadings, as
in the fillet.
The outer edges of the main structures of the fillet and tyre are raised a little
in the circle to form ridges at the back of which I fasten the cover.

page_text: The beadings may also be of solid material; in which case, they are braized
or otherwise joined or attached to the main structure; which is made to border
them, against which they come.
I now construct the springs; which may be of round, square or flat wire or
band, in short lengths, or in circles. If I make them divided I take the lengths
and groove twice round each end so that they may fit into the material of the
hollow beadings at the enterance and exits of the holes. If I use flat springs I
make their ends cylindrical; which I also groove. If I use solid beadings, I,
instead of grooving the springs, make the holes larger so that I may pass through
springs with heads; or I may pass them through the ordinary holes and bend
the ends afterwards. If I make flat springs I form lips either first or
afterwards. In case of the circle or circular springs I groove them in a similar
manner to the others or I form cranks, on opposite sides, bending inwards, or I
put stops or butts; which all are intended to keep the springs in position after
fixing. If circle springs are used I shall have to alter the holes in the beadings
by cutting out that part to them on the inner surface which face each other,
and, in fixing the springs, I compress them at the crank or stop sides which
pass between each of the two beadings as the springs are inserted in the cuts, top
and bottom, in which they pivot. The half circle springs are fixed by bending
them and passing there ends through the holes top and bottom in the beadings
of fillet and tyre where the grooves catch in the material at the enterance and
exits.
I may cover the surface of the tyre with less refractory material of organic
origin.
I also cover the sides, in a similar way as before mentioned; but on the inner
side of the ridges raised between the fillet and tyre.
Again,
3) I construct a hollowed fillet in shape of a rim I turn the edges over inwards,
leaving a ridge and narrow surface on both sides, and carry the material round upon
itself forming square beadings over the main structure; the outer surfaces of
which, facing a similar structure at the back of the tyre, I indent with a shallow
groove, along the sides of which, I pierce or drill, at suitable distances from each
other, a row of square, oval or round holes, which pass through the beadings;
opposite their exits I indent the main structure. Or, if 1 use solid beadings, I
may groove the inner side of the fillet opposite to the row of exits. Both these
beadings may be braized or otherwise joined to the rim which may lap over at the
sides to form bounderies to the dirt cover.
I also construct a tyre which, being independent of spokes, I provide with a
diaphragm or stay, made by lapping in, at the outer circumferance, material so
that it meets at the angles, leaving the rest of the space hollow, in section, like a
syrop-drop. I cover the outer surface with organic material which is ribbed or
otherwise excoriated to prevent slipping. The beadings I construct similar
pricely to those in the fillet but in reverse.
I now construct springs which shall have independent vertical and perpen-
dicular action at both ends when in tension, expansion or compression I may
make them of round or square wire I coil or twist it into two circles, the stems
leaving the twin circles at the extreme tangents and on opposite sides, the inner
tangents going into one another from opposite sides of the circles, shaping, as it
were, rounded spectacle rims in which the bridge is waved lower on one side than
on the other and the stems similarly out of position.
I place the tyre over the fillet filling in the space between, on both sides, with
a radius of springs radiating from the pivot or hub; which I fix by pressing
them together and passing the stems into the holes in the beadings, top and
bottom, so that they impinge on the inner side in the indented or grooved part
of the main structures resting the ends of the circles in the grooves in the beadings
where they hold the structure in tension.
I cover the sides, between the boundaries of the ridges, in fillet and tyre, with

page_text: material as before, by snaps clasps or cement. I propose that the cover shall be
elastic; stretching and shrinking with the resilience.
In another way.
4) I construct a fillet precisely similar to that in No. 3 and braiz or suitably
join the edges of the beadings to the main structure. On the inner upper corners,
forming the square of the beadings, I cut or sink a line or groove into which
I fix or rest the edges of a hollow superstructure, of an oval shape, forming a
tranans tyre; the rounded part facing the inner side of the tyre-proper; this I
may also cover with an organic material, less fractious, to any thickness I may
require.
I now construct a tyre-proper rounded to the center of the outer circum-
ferance which I rib or excoriate to prevent slipping and strengthen with a
diaphragm or stay by lapping in, at the outer center, material which I flatten
together to form the required structure at the back of the tyre 1 construct the
beadings precisely as in the fillet but in reverse. In the lines or grooves in the
inner upper corners of the beadings I rest or fix a superstructure; shaped, in
section, like a frustum, the outer and narrower part, facing the fillet, I make
concave or channelled, in which the tranans tyre travels.
I now make the springs, of square or round wire, for similar action as in
No. 3. To obtain this I coil or twist it in such a way that I form a circle at each
end of a bow, on different sides, with their stems continuing the line of the bow
but on different sides of the circles; like a pair of pince-nez.
These springs I compress between the fillet and tyre, inserting the stems
through the holes in both upper and lower beadings, round both sides in radius,
lodging or resting the butt ends of the circles in the grooves; when the springs
expand they keep the structure in tension. Thus the springs will compress or
expand in harmony to the perpendicular and vertical motion.
I cover the springs in the same manner as before mentioned.
Again; I further describe
5) I construct a fillet precisely similar to that in No. 3, save that the beadings
are narrower and that I sink the spoke ends in a groove which I cover to keep
the surface smooth.
I also construct a tyre precisely similar to that in No. 3 save that the beadings
are narrower, and that I fold in a diaphragm, in the center of the back, to form
a stay; which I make meet at the edges or angles, proloning the structure to
the interior where I keep it hollow and in shape, in section, like a parachute.
This diaphragm I intend as a check to the fillet, to prevent straining the springs,
by acting as a tranans tyre on the inner surface of the fillet. I may cover the
travelling parts of the surface with any organic substance suitable to allay
tremor.
The springs I make of round or square wire and shape them into single oval
circles the stems folding over on one of the longer sides at an acute tangent (like
a breeve on a line raised in the center).
I fix the springs between fillet and tyre, in radius, on both sides by compressing
them and passing the stems through the holes, in the beadings, top and bottom
abutting the ends against the back of the main structures. The ovaled ends
resting in the grooves.
I cover the sides between the ridges in the same way as before mentioned.
In a further description
6.) I construct a fillet in the same way as before mentioned, but I make the
beadings, in section, barrel shaped and use no grooves. Through the Hattened
surface in the beadings, facing the same structure in the tyre, I punch pierce drill
or cut oval, oblong, or square holes at convenient distances apart through and
out at the other side.
I also construct a tyre similarly as before; and the beadings, in section, barrel
shaped and make holes as in the fillet only in reverse. I also rib or otherwise
excoriate the surface to prevent slipping, and flatten the diaphragm together.

page_text: I coil or twist round or square wire in such a way that I form alternate circles
or rings to which on the furthest point from the stem, are formed bills or lips,
like those formed in dress hooks but in a straight line, not bent over, (like a
ducks bill), the stem-line waving in zig zag to each alternate circle, forming
one continuous spring for each side or radius; they may also be constructed in
sections of alternate one and two circles. I also make single springs; forming the
bill or lip, first by folding the wire in two making the bill and then a circle
bring the wire parallel for a short distance and again making a circle following
it by a short stem which may be braized together.
I compress the zig zags from the bills and fix the bills through the holes
alternately top and bottom of the holes in the beadings of fillet and tyre where
they hold the structure in tension. The single springs are fixed by compressing
the two circles towards each other which opens the parallels into ovals; the
bills are fixed in the same way as with the continuous springs.
I cover the works in the same manner as before mentioned.
I also, in another way
7.) I construct the fillet and turn the sides outwards upon themselves forming
beadings of two rectangular sides; the vertical sides backing each other; the
horizontal sides facing similar structures in the tyre I cover these with a corru-
gated bottom radiating at right angles I surmount the vertical sides with a, in
section, frustum; inverting the upper end to form a channel for a tranans tyre
I join the edges to the main structure; or the fillet may be made in one piece
with the horizontal sides corrugated.
I now construct the tyre proper rounding it to the center circumferance and rib
or excoriate the surface to prevent slipping I construct similar beadings as in the
fillet but in reverse, and surmount the vertical sides with an oval shaped tranans
tyre joined on by braizing, or the whole tyre may be made in one piece and dealt
with as in the fillet I cover the tranans tyre with organic material so that it acts
noislessly.
I now construct, of round or square wire, springs which I coil several times for
each circle which branch out alternately in zig zag waves, in one continuous
spring, for each side. It may also be construct in sets of three coils, one at each
point and one at the apex.
I place the tyre over the fillet and fill in the space in each side with a set
of springs by placing the coils alternately top and bottom into the corrugations
in the beadings where I hold them in position with flat rings which at the same
time form a boundary and surface against which I afix the cover. It may also
be ridged out of the material of the main structure. The coils being of such a
bredth that they hold the structure erect and prevent collapse.
To illustrate another method
8) I construct a fillet of before mentioned materials and shaped as No. 6 and
sink the spokes in a groove which I cover for strength I slope the material out-
wards and turn in the edges, leaving a ridge I form beadings, inside and under
the structure, in section, a bulged frustum the base facing a similar structure in
the tyre. Through these I drill or pierce, at suitable distances apart, round or
square or oblong holes so that they impinge on the inner surface of the main
structure which is here indented or grooved on the enterance surface. I indent
or sink spaces round each hole.
I also construct a tyre with similar beadings in reverse; the rounded outer
surface I lap in at the center to form a diaphragm at the back meeting at the
edges or angles, which may be joined, bringing it out at some distance in the
interior in a round hollow tranans tyre, to act as a support to the springs, under
strain, by travelling on the inner surface of the fillet.
In this case I construct the springs each in two parts, each part shaped like
a sickle the rounded end; or crump, circled at right angles to form a hole; the
other end I turn back slightly and form a stem. I now pass the stems of each

page_text: through the holes in the other and so combine them forming circles; the stems
standing out as axels to each pole.
I put the springs in position by pressing them at the poles together and passing
the stems through the holes in the beadings top and and bottom of fillet and tyre on
both sides of the radius abutting the rings into the sunken spaces around the
holes.
I cover the works with material as before and in the same manner.
I finally further illustrate these principles for heavy traffic by a tyre for cab
wheels
9) I use wrought iron or tyring steel I construct the fillet, or superstructure
by working the material from the outer band, leaving a given surface or ledge,
into a center raised structure, at right angles; which I groove or invert to
make a channel, leaving the under side hollow. I chase out a line, on both sides
of the center structure, in the surface of the ledges along the sides of which, at
suitable distances apart, I drill or punch, a single row, of round or square holes.
I construct the tyre proper by slightly rounding the material to the outer
center where I lap in material to make a tranans tyre which also acts as a stay
or diaphragm, in section, shaped like a pear drop I also groove out or chase a line
on the underside on both sides in the ledges facing these in the fillet and drill or
punch similar holes only on the opposite border of the grooves.
For this illustration I take, say, the spectacle spring of No. 3, of much stronger
make. I place the tyre over the fillet and fill the space between on both sides,
by pressing and passing the stems through the holes, top and bottom and resting
the butt ends of the circles in the grooves where they are held in place.
The inner edges of the outer surface of fillet and tyre I chase out a space into
which I fit the cover over which I put a flat ring and screw to the main structure.
I apply the same principles to motor cars trams, busses and, even, railway &
traction wheels.
I may say that though I have not particularized the material to be used in each
instance set out yet I claim the right to have done so only avoiding mention in
each case to save repetition and for the sake of brevity.
In conclusion I may say that it is open to me, and my intention, to use any of
the springs, fillets or rims or tyres or tranans tyres or superstructures, here
described, and all or any of them in combination with each or every shape, not
alone as I have here combined them, but as may suit my purpose as varying the
principles which I here seek to protect; or as exegency or manufacture may
require by taking one for the other or any of the various constructions and
intermanipulating them as the case may demand.
It is intended that drawings or drafts shall be delivered with the Final
Specification so that errors of omission or misdiscription may be discovered
and rectified by their help.
As there are some structural additions or differences I must add another
illustration
2**) I make the fillet and tyre as in No. 2* but I bring the beadings under, on
their inner sides, in line with the circle and drill or pierce round or square holes
through them, at convenient distances apart, in line also with the circle, and rib
or excoriate the tyre to prevent slipping.
I make the springs of square or round wire or flat band and in simple, given or
suitable, lengths: which I bend into arcs as I pass them through the holes, top
and bottom, in the beadings of fillet and tyre and abutt the ends against a
short diaphragm in the fillet and against that in the tyre. I cover as before.
Or I make a fillet and tyre without beadings but turn the edges at right angles
into plain which I pierce with holes, as before I corrugate the structures radiating
with their circles, the grooves, in the inner sides, in line with each hole: at a
convenient part, of these grooves, from the border I make two cuts crosswise into
the material and press the middle of them back outwards. in reverse groove of
the corrugation, so that it may form a guide or hole in which the spring continues,

page_text: and still further away from the border, and along the groove I cut crosswise an
arc with the circle facing the border and the base in line with the spokes the
inner piece of this are I press from outside at right angles into a lip or rest
or ledge against which I abutt one end of the springs which I pass through the
border holes and through the other holes and in this way fix them. I cover as
before.
Or I construct the fillet and tyre without border and make two such double
cuts across the corrugations; through which pass the springs which are secured
as in the former.
The two paragraphs closing No. 9 description apply to these forgoing addi-
tional descriptions and I wish them so to be considered.
Referring to No. 2**
Or I do without the corrugations and let in a flat band on the inner side round
where I cut twice through the material to form a guide hole for the springs; this
band I turn up at both edges in shape of a trough; that side turned up facing the
border I pierce with holes opposite to those in the border. The material of the
trough being sunk into the material of the structures level with them.
pass through the holes in the borders and through the holes in the nearest sides
of the trough the hair-springs which abut with their ends against the other and
further sides of the troughs which act as a stay to their further movements.

Improvements in or relating to Spring Tyres and Kims.
I, HENRY DE LASPÉE, 153, Broomwood Road, Wandsworth, S.W., Manufacturer,
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:-
The object of my invention is by means of improvements relating to spring tyres
and rims to be enabled to construct a wheel combining lightness, resiliency, and
stability to a high degree.
In carrying out my invention I use springs of a great variety of form between
the felly and the tyre. I can also use an additional tyre, which I term the
"tranans" tyre, thereby distinguishing it from the tyre proper, and implying the
easy movement of the improved wheel. The "tranans" tyre may be secured
to the felly or to the tyre proper, and when the springs are compressed, the
"
tranans tyre fits into a corresponding groove or curved surface in the opposite
part of the wheel. This surface I call the track. Between the track and the tyre
proper may also place an elastic diaphragm or wad to improve the resilience of
"
the wheel.
To show clearly how my invention is carried out I furnish drawings in which
the same parts are represented by the same letters throughout.
Fig. 1 is a diagram of part of wheel with a portion of cover K removed showing
springs Con one side in tension.
Fig. 2 shows the spring C before being placed in the wheel.
Fig. 3 is a transverse section through the wheel.
The spokes A are secured to the felly B, and, in preference, to a depression B
in the felly. The felly, which is made of steel or other suitable material, is
concave within facing the tyre. On both sides of the cavity a ledge or beading is
made in the felly by bending it outwards, then downwards, then backwards, and
finally upwards, the end being braised to the felly. These beadings are shown
at B, B. E is the "tranans" tyre of india rubber or other suitable material
solid or hollow. F is the ordinary tyre. Within this is a structure H which

page_text: I call the track made of steel or other suitable material, and shaped somewhat
similarly but in the reverse position to the felly. The beadings of H are shown
at H. Between the tyre F and track beadings H' I place elastic diaphrams
or wads J, the tyre being brought over as shown in the drawing at S, S. The
springs C are placed in position by pressing the circled ends D alternately into the
felly and tyre track beadings B' & H¹. K, K, are coverings or envelopes between
the beadings of the felly and the track to enclose springs C, made of celluloid, or
light metal, or other suitable material, that part covering the felly beadings
being attached with a flexible or elastic joint K¹. The beadings B¹ of the felly
extend beyond the envelopes K as shown in Fig. 3 so that moisture may drop off
clear and not percolate into the interior of the wheel. G is an elastic covering
on the outer tyre.
Fig. 4 shows another form of spring.
Fig. 5 is a section showing a modification of the arrangement. The track is
reduced to the curved guide pieces F2, F2, made from a continuation of the
material of tyre F. The flexible joint K is here shown in the middle of the
cover K, which cover is in two parts, the felly part moving on the inner side
of the tyre part. The tyre F is shown with corrugations F', F¹.
Fig. 6 is another form of spring.

Fig. 7 shows in section another modification of arrangement for the wheel. In
this case there is no tranans" tyre. The felly B is made in the form shown,
the beadings B being turned in and back, then downwards, and finally in again,
but not carried back and braised as in Fig. 3. The straight ends of springs C
in Fig. 6 are inserted in holes of these beadings and of the corresponding ones F2
of tyre F. The ends of flexible covering K are secured in the narrow grooves of
beadings as shown. The tyre F is turned inwardly to form a stay L which prevents
the tyre going out of circle. The elastic covering G is furnished with corru-
gations G. The curved parts of springs C rest in grooves or indentations in the
beadings B¹, Fa, as shown in Fig. 7.
Fig. 8 shows another form of spring.
Fig. 9 shows in section a modification of the whole arrangement of the wheel.
The straight ends of springs C pass through beadings B1, F2, and parts of the
curves of the spring are inserted in grooves or indentations on the said beadings.
The tyre F forms an inlap L as shown. The corrugations are filled with
india rubber or other suitable material. The edges of the beadings B are bent
in so as to form grooves rectangular in section as shown at E¹. The tranans
tyre E rests upon or is secured to these grooves E. Corresponding grooves are
made in beadings F for track H. The "tranans" tyre E can in this case be
made of thin metal.

Fig. 11 shows in section a modification of the whole arangement of the wheel.
The straight ends of springs pass through beadings B¹, and the other ends
through beadings F2 and rest on notches F in tyre F. The inlap L is furnished
with an elastic covering L', which on compression of springs fits in B3 a curved
surface formed on the inner side of felly B. 14 are solid beadings secured to
beadings B¹ of felly B. The beadings F are also solid and secured to beadings F²
of tyre F.
Figs. 12, 13, & 14 show other forms of springs.
Fig. 15 shows in section another modification of the whole arrangement of the
wheel. The beadings B & F are made approximately oval or barrel shaped as
shown. The straight ends of springs C pass through them. The tyre F is corru-
gated at F and the centre bend is filled with india rubber G or other suitable
material. There is a small inlap L.
Fig. 16 shows another form of springs.
Fig. 17 shows in section another modification of the whole arrangement of the
wheel. The curved parts of springs fit into curved recesses in felly B and tyre F.
The tyre F is continued so as to form "tranans" tyre E which is covered at E²

page_text: with india rubber. The fеlly D is continued so as to form a corresponding sit
or track P to receive E³ on compression of springs C.
Fig. 18 shows another form of springs.
Fig. 19 is view of part of circumference of wheel with cover removed.
Fig. 20 is section of same.
The curved ends of springs rest in sockets in felly B & tyre F, and the straight
ends of adjacent springs are pushed through orifices D and pass through
beadings, thus securing springs.
Fig. 21 represents part of circumference of heavy wheel.
Fig. 22 is section of same.
The felly and tyre are in this case solid and no beadings are required, the
springs being secured in the mass of the felly or tyre. If provided with a flange
this type is suitable for railway & similar wheels.
Figs. 23 & 24 show wire lengths which function as springs in the case of light
wheels shown in diagram in Fig. 25 and in section in Fig. 26. The felly Bis
made with small inlaps O and the tyre F also. The spring C as shown in Fig. 24
is passed through holes in the inlaps O of felly and is secured in a notch in the butt
end inlap 01. At the other end it passes through the inlaps O of tyre F and ends
in a slight notch on inlap L. The form of spring C shown in Fig. 23 with
twists R should be inserted so that the twist R comes flat against the envelope
or covering in contact with the inner surface of outlaps R₁ of felly and tyre.
Both the tyre and felly as shown in Fig. 26 are continued a little beyond the first
inlap, as shown at R¹, to form a groove for the insertion of covering K, which is
not shown in this figure. Q is thin strip of sheet steel or other suitable material
secured by the spoke A as shown in Fig. 26. This serves as a guide to inlap L if,
on compression of springs, the said inlap L should diverge a little to one side.
Having now particularly described and ascertained the nature of said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
