IMPROVEMENTS IN MACHINES FOR GRINDING POLISHING GRAINING AND OTHERWISE PREPARING STONES AND PRINTING SURFACES
Year: 1885

page_text: ALEXANDER HERVEY SEGGIE Broughton Market, Edinburgh, Scotland, Engineer,
do hereby declare the nature of my invention for IMPROVEMENTS IN MACHINES
FOR GRINDING POLISHING GRAINING AND OTHERWISE PREPARING STONES AND
PRINTING SURFACES, to be as follows:-
In a machine having a compound swinging arm with universal joints provided
with elongating spindle, guided in two bushes, fixed at certain distances, which
permits the apparatuses which for grinding, are made with radial projections and
perforations for sand and for polishing and graining suitable for grasping and
making use of, the polishing and graining materials.
In a machine, with the iron frame so designed and with gearing so arranged, the
driving bevel pinion, being above the driven, that head room is economized, thereby
securing important advantages, in the efficient working of the machine.

page_text: ALEXANDER HERVEY SEGGIE Broughton Market Edinburgh Engineer I do
hereby declare the nature of my invention for IMPROVEMENTS IN MACHINES
FOR GRINDING, POLISHING AND OTHERWISE PREPARING STONES AND PRINTING
SURFACES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
1st In a machine with the Iron frame so designed and the gear so arranged, the
driven bevel pinion A being above the driving Bevel pinion, A' that headroom is
economized, thereby securing important advantages in the efficient working of the
machine.
2nd In a machine having a compound swinging arm, B with universal joints and
provided with an elongating spindle C of certain fixed weights, guided in two
bushes K K fixed at certain distances, which permits the apparatuses for grinding,
polishing, graining and otherwise preparing the surfaces, being moved freely and
steadily over it, thereby producing even and level surfaces.
3rd In a machine having in combination with the swinging arm and elongating
spindle, an apparatus for grinding D, consisting of a circular disc, provided with
radial projections and perforations to receive the grinding sand, and with catches
on top for connecting to joint on elongating spindle.
4th In a machine, having in combination with the swinging arm and elongating
spindle, an apparatus consisting of a rectangular cast iron box, E with or without
screws for grasping the material for polishing, graining and otherwise preparing
the surface, and provided with catches on top for connecting to joint on elongating
spindle.
5th In a machine, having in combination with the swinging arm and elongating
spindle, an apparatus consisting of a rectangular cast iron frame F of a fixed weight,
for grasping the material for polishing, graining and otherwise preparing the
surface, provided with catches on top for connecting to joint on elongating spindle.
6th In a machine, having an apparatus for graining Zinc and similar surfaces
consisting of a rectangular block of wood, G, provided with circular projection or
projections, faced with Zinc, which can be used in combination with apparatus
described in No 5.
7th In a machine, provided with an arrangement H for disengaging the grinding,
polishing or graining apparatuses, which arrangement consists of two sliding
snibs S S¹, carried in the lower joint on the elongating spindle, provided with two
nobs and held in position by a spiral spring, which on being compressed by pressure
applied to the nobs on the sliding snibs, allows the snibs to pass clear of the catches
provided for them on the aforementioned apparatuses, thereby detaching either or
any of the apparatuses as may be.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed what I claim is
1st A machine, having an iron frame of the design and arrangement of gear as
above described.
2nd In combination with the foregoing a compound swinging arm and elongating
spindle of the construction as described and provided with the separate apparatuses
for grinding, polishing, graining and otherwise preparing the surface, all substan-
tially as herein before described.
3rd An arrangement for disengaging the grinding, polishing, and graining
apparatuses as described above.
