We, ROBERT SOMMERVILLE and JOHN RICHARDSON, of the Firm of Sommervillo
& Richardson, Engineers and Blacksmiths, Murdoch Terrace, Dundee Street,
Edinburgh, North Britain, do hereby declare the nature of this invention to be
as follows:
This invention relates to a glazing machine for laundry purposes and is
particularly applicable for the glazing of linen such as collars, cuffs, shirt fronts
and such like.
It consists in the employment of two rollers carried between standards. The
top or larger roller, of metal, is internally heated by means of gas burners.
The under or smaller rollers is covered with indiarubber or other material. The
two rollers are rotated by means of gearing at the side of the machine operated
by hand or power, the gearing being such that a motion of more rapid rotation
is given to the upper or heated roller.
The under or rubber roller is kept in contact (when the machine is in operation)
with the heated roller by means of eccentrics keyed upon a shaft below the
rubber roller which eccentrics bear against sliding bushes of the rubber roller.
The end of the eccentric shaft is carried in a bush or bearing in a frame or box
at the outside of the machine standard; the same arrangement at the outside of
the other standard of the machine. The said bush or bearing of each end of
the eccentric spindle rests upon a rubber block or other spring within the box.
The amount of pressure for the eccentrics to exert against the sliding bearings
of the rubber roller is regulated by means of a pinching screw, or its equivalent,
which passes through the bottom of the bearing box of the eccentric shaft, and
against the underside of the rubber block, but the extent of the upward adjust-
ment of the said shaft is regulated by means of a tapered cutter which is provided
across the top of the bush box. By moving the said cutter backwards or forwards
by means of a screw, the rubber roller, through the medium of the eccentric shaft,
is thus set relatively with the heated roller so that the wear of the rubber roller can
be taken up by adjusting the cutter. When the machine is in operation and it
is desired to bring the rubber roller into contact with the heated roller, the
shaft carrying the eccentrics is given a motion of a partial rotation by means
of a lever at the one side of the machine, so that varying or gradual pressure
may be given to the rubber roller against the heated roller.

page_text: We, ROBERT SOMMERVILLE and JOHN RICHARDSON, of the Firm of Sommerville
and Richardson, Engineers and Blacksmiths, Murdoch Terrace, Dundee Street,
Edinburgh, N.B., 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 a glazing machine for laundry purposes and is
particularly applicable for the glazing of linen such as collars, cuffs, shirt fronts
and such like.
In the accompanying drawings
Fig. 1 is an elevation and
Fig. 2 an end view of our improved machine.
Referring-to-the-said_drawings, we employ two rollers, carried between stan-
dards A the top-or larger roller B being-of-polished metal and heated internally
by means of gas jets supplied from a Bunsen burner C. The under-or-smaller
roller D is covered with indiarubber and the two rollers are rotated, through the
toothed pinions E driven by power or by hand, at the same speed, the diameters
of the rollers however being preferably in the ratio of about 3 to 1 so that the
larger has a slipping action around the smaller roller, thus effecting the desired
glazing..
The employment of the rubber roller, in combination with the heated metal
roller ensures the surface of the article being glazed evenly, as the rubber of
the lower roller yields to the fold or turned in edge of a collar, for example, and
presents an even surface to the glazing roller. By the use also of the rubber
roller the life of the articles to be glazed is increased as the wear is found to be
diminished.
.
The upper roller B is mounted in fixed bearings in the, standards, the journal b
being tormed as a trunnion to allow the gas heating tube E to pass there-through.
The spindle c of the lower or rubber covered roller C is carried at each end
in a sliding bush which is acted upon from below by an eccentric f keyed upon
the shaft which is carried in adjustable bearings f. The end of the shaft f
is fitted with a handle G which when turned to the position shown in the figures
causes the eccentrics to raise the sliding bushes Fand bring the rubber roller
in contact with the upper. By rotating the handle until it is arrested by the
regulated
stop g the rubber. roller is lowered. The pressure between the rollers
and adjusted by a pinching screw which acts upon the under side of each of
the bushes or bearings f.
His the table by which the work is fed to the machine and J the table which
conducts the work from the machine to the receiving receptacle, both of the
said tables being preferably connected removably to the supporting brackets j
by any convenient arrangement such as by a button or snib at each end of the
tables, so that the tables can be removed" at will.
If desired to obtain a greater heating effect from the gas jets, we may dispense
with the ordinary Bunsen burner, as shewn, and substitute therefor a burner
having a large bulb and air duct, the bulb being say three in inches in diameter;
the said bulb to the underside of which the gas tap is secured, being screwed to the
depending arm of an elbowed tube which forms the connection between it and
the tube E¹.
In lieu of employing rollers of different sizes driven at the same speed, we
may if desired employ rollers of the same size driven at different speeds to effect
the slipping action between them.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is:-
1. The general arrangement, construction and combination of parts constituting
the glazing machine for laundry purposes, substantially as herein before described
and shewn in the accompanying drawings.
2. In glazing machines for laundry purposes, the combination with the heated
metal roller B of the rubber covered roller 1; operating substantially in the
manner as and for the purposes hereinbefore described and shewn in the accom-
panying drawings.
3. In a glazing machine for laundry purposes, the means whereby the rubber
roller D is raised or lowered into or out of contact with the metal roller B, con-
sisting of the sliding bushes F carrying the spindle C of the rubber roller D,
acted upon by the eccentrics f through the handle G; or the mechanical equiva-
lent of the said parts; substantially as herein before described and shewn in the
accompanying drawings.
