page_text: LETTERS PATENT to Henry Mulliner, of the Royal Borough of Leamington,
in the County of Warwick, Carriage Manufacturer, for an Invention of
*IMPROVEMENTS IN CONNECTION WITH CARRIAGES FOR COMMON AND OTHER
ROADS."
"
PROVISIONAL SPECIFICATION left by the said Henry Mulliner at the
Office of the Commissioners of Patents on the 10th January 1880.
HENRY MULLINER, of the Royal Borough of Leamington, in the County of
Warwick, Carriage Manufacturer. "IMPROVEMENTS IN CONNECTION WITH
CARRIAGES FOR COMMON AND OTHER ROADS."
The object of this Invention is moulding india rubber or rubber compound into
special form, and combining therewith a plate of metal arranged between the rubber
and the lower spring plate of a carriage spring to reduce noise while travelling,
also to prevent strain usually caused by roughness and inequalities of the road.
The rubber or rubber compound is nearly square in shape, and has deep recesses
on two of its sides, into which the legs of the axle clip engage, the projecting lips at
each end of the recesses serving to hold the rubber in position.
The rubber is hollow, and the interior is shaped to fit recessed portions of the
axle, the shoulders of the recesses preventing slip or end on play of the rubber,
and the pressure of the rubber lips against the clip any side slip or lateral play.
The plate bears upon the top surface of the rubber, and is shaped to prevent the
rubber being squeezed from excess of top pressure.

the said Henry Mulliner in the Great Seal Patent Office on the 9th July
1880.
HENRY MULLINER, of the Royal Borough of Leamington, in the County of
Warwick, Carriage Manufacturer. "IMPROVEMENTS IN CONNECTION WITH
CARRIAGES FOR COMMON AND OTHER ROADS."
The object of this Invention is moulding india rubber or rubber compound into
special form, and combining therewith a plate of metal arranged between the
rubber and the lower spring plate of a carriage spring to reduce noise while
travelling, also to prevent strain usually caused by roughness and inequalities of
the road.
The rubber or rubber compound is nearly square in shape, and has deep recesses
on two of its sides, into which the legs of the axle clip engage, the projecting lips at
each end of the recesses serving to hold the rubber in position.
The rubber is hollow, and the interior is shaped to fit recessed portions of the
axle, the shoulders of the recesses preventing slip or end on play, the rubber and
the pressure of the rubber lips against the clip preventing any side slip or lateral
play. The plate bears upon the top surface of the rubber, and is shaped to prevent
the rubber being squeezed from excess of top pressure.
My Invention is clearly represented in the annexed Drawings, in which Figure 1
shows the moulded rubber or rubber compound block A with two projecting lips
B, B, on two of its sides, forming between them recesses C, C, into which the legs
D, D, of the clip strap E, Figure 2, engage as before described.
Figure 3 represents the top plate F with curved edges G, G, for pocketing and
preventing the rubber spreading beyond fixed limits under excess of weight or
otherwise. This plate rests upon the rubber, as in Figure 4, which is an end view
with the axle H in section, the axle baving cheeks or shoulders I, I, on its two
sides, as in Figure 5, that the rubber block A is prevented shifting from its position
when slipped over the axle into the recesses J, J, and in the position which it
occupies directly under the spring K, as shown by Figure 4.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,—
The combination of the plate F and moulded rubber block A between the springs
and clips of carriage axles, as described, and constructed and arranged as shown in
the annexed Drawings.
Secondly. I claim the employment of curved side edged metal plates between
rubber blocks (which encircle the axles of carriages) and the springs of carriages, as
described and shown in Figures 3 and 4 of the annexed Drawings.
In witness whereof, I, the said Henry Mulliner, have hereunto set my hand
and seal, this Eighth day of July, in the year of our Lord One thousand
eight hundred and eighty.
