I WILLIAM WILSON HORN of Somerset Chambers 151 Strand London of the firm
of Horn & Son Patent Agents do hereby declare the nature of this invention to bo as
follows:-
In this my invention I support the whole of the mechanism on a suitably formed
stand preferably constructed of two flat pieces of wood or iron placed one above the
other, the upper one supported upon the lower one by four or more suitable pillars.
Upon the upper part of the stand, and projecting over one side are two cylinders,
which revolve on two shafts running parallel to one another and journaled in bearings
placed at suitable distances apart. The revolving cylinders are covered on their
surfaces by an elastic covering adapted to receive the articles to be burnished. The
peripherys of said cylinders are also surrounded by suitable bands and are provided
with spring clamp bars for holding the articles to be burnished in place.
The opposite ends of the parallel shafts are provided with worm wheels which take
up the rotary motion communicated to them by two worms supported on two vertical
shafts which are suitable journaled on the lower bed plate of the stand and pass
through the upper bed plate of stand. The lower ends of these said shafts are also
provided with worn wheels, and receive the motion communicated to them by a worm
supported on a horizontal shaft suitably journaled on the lower bed plate of the stand.
Upon the said horizontal shaft is keyed or otherwise fixed a conical pulley which is set
in motion by a driving belt, which transmits the rotary motion from an upper
horizontal shaft, suitably journaled upon the upper bed plate of stand. On one end
of this said upper horizontal shaft is keyed the main driving pulley, and on the other

page_text: ikoyed a disc provided with a projecting pin which transmits a reciprocating move-
ment to a connecting rod, which in turn gives motion to a bar running in a suitable
guide. To the end of this said bar and at right angles to it are fixed the burnishers
which come between the revolving cylinders and are pressed outwards against the said
cylinders by means of suitable springs Upon the upper bed plate and elevated
above the revolving cylinders by a suitable stand, is situated a liquid reservoir which
is provided with leading pipes in combination with a screw stem extending through
the pipes and projecting below the latter to guide and direct the drip to the
burnishers.
My improved burnishing machine is also provided with a fixed knife holder, and
also a rotating knife cylinder or drum.
The mode of working my machine is as follows:-
Motion is transmitted to the upper horizontal shaft by the main driving belt and
pulley which causes the burnishers to reciprocate between the revolving discs upon
which is clampled the articles to be burnished, the said articles to be burnished revolving
as the burnishers move with a to and fro movement upon their surface.

page_text: An Improved Burnishing Machine.
I, WILLIAM WILSON HORN, of 151 Strand Middlesex, Patent Agent (communi-
cated to me from abroad, by George B. Kelley of Rockford Illinois, United States of
America,) 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 invention relates to new and useful improvements in Burnishing-Machines, of
which the following is a full description, reference being had to the accompanying
drawings, in which-
Fig. 1 is a longitudinal section of the drum or cylinder and its shafts; Fig. 2, a
detail showing the construction and application of the burnishers; Figs. 3. & 4 detail
views in part section of an alternativo form of the construction and application of
the burnishers. Fig. 5 a detail of the angular portion of the burnishing rod, with
its sides partly broken away at the ends; Fig. 6a perspective view, and Fig. 7 detail
of a drip-faucet. Fig. 6 is on a reduced scale.
The object of this invention is to provide a machine in which the articles to be
burnished can be easily attached and detached, to make the machine continuous in its
operation, and to generally improve its construction and operation. The nature of
my improvements will be found embodied in the claims.
In the drawings, A represents the bed-plate; A, the base-plate; B, a liquid-
reservoir ab, the cylinder or drum; c, elastic or rubber covering; d, a table-
knife in position; e, sockets or holes for the reception of the articles to be
burnished, the upper or inner ring of the cylinder; y, the outer ring, having a
flange, hij, shafts; k, friction-clutch; 112, worm-wheels; 1113, worms; m, shaft-
cap; a, hand-wheel; o, screw-cap; P, angular section of the burnishing-shaft, pl, its
supporting bracket or box; y, section of burnishing-shaft carrying the burnishers;
, adjustable connection for the pitmans; t, crank-wheel having an adjusting-
groove, ;
', cone-pulleys, arms or sockets for attaching the burnishers to
their bar;, springs; x, movable shafts or spindles carrying the burnishing-tools;
3, power shaft and pulley y', belt; ac, spring-clips for holding the upper or
outer end of the articles to be burnished: ', support for reservoir; e'; pipe from
reservoir, having branches, drip-faucets; 4, cut-off valve or stop.
;
The bed-plate A can be made in the form shown or in any other suitable form, and
it is to be connected to, or with the base-plate A', as shown, or to any suitable
supporting-iable or frame-work, and it be readily understood that the machine may
be operated when in either a vertical or horizontal position or at any intermediate
angle.
The drum or cylinder a is preferably cast in the form shown, with its supporting
hub & projecting inwardly.
The outer end is provided with a band, which partly holds the elastic rubber or
bed in position, and to which the clips or clamps a 6₁e are attached. These clips
are made as shown in Fig. 1, the part a' being pivoted and given a proper pressure to
hold the end of the article by the spring 6, which bears against the arm or projection
which is rigidly attached to the form f The inner end of the cylinder is
provided with a metal ring, y, which has a Hange, h, projecting slightly above the

page_text: lower end of the rubber or other elastic bed. The knives d, or other articles to be
burnished, have their points inserted under the flange and their upper ends
clamped and held by the clamp a¹. The spring 6" allows the arm a¹ to be opened for
the purpose of inserting and taking out the articles.
C
;
The bed c is made of a continuous rubber band entirely surrounding the cylinder a,
and provided with suitable molds or recesses, e, to receive projecting portions of the
articles to be burnished. These molds or recesses will vary according to the shape or
contour of the articles to be burnished, the form shown being adapted to table or
case knives.
Different rubber beds may be applied to the same cylinders but
ordinarily it will be preferable to have complete cylinders adapted to the different
articles to be burnished where there is any considerable difference in shape or
length, or a brass or other metal sleeve or collar may be made to fit and fasten to
the same cylinders and to this sleeve the flange and band with its clips or
clamps ac and elastic bed may be fastened, and the whole removed or changed
for different lengths or sizes, without removal of the cylinders or drums from the
shafts.
The flange h, with the ring g, is usually made adjustable, so as to lap more or less
over the cylinder, and removable so that the covering e may be changed without
removing the ring and for this purpose the projecting flange at the lower or inner
end of the cylinder is omitted and the inner portion of the ring g made wider and
provided with any suitable attaching and adjusting devices; bui. this will not be
necessary when only one kind of article is to be burnished. The cylinders a are
primarily supported upon the shafts, which are hollow, and through which the
shafts j pass.
The worm-wheels are attached to or made a part of the shafts, and the worm-
wheel (formed in one piece with or fitted upon the shaft i) is provided with a
bevelled recess to receive the friction clutch k which is formed with a corresponding
bevel. The friction clutch is loosely screwed upon the screw which screw forms
part of the shaft j. By turning the wheel n (which wheel is attached to the shaft j
by a set-screw) the screw draws the clutch against the worm-wheel 7 causing the
said wheel and clutch to impinge, and shaft i to move longitudinally on the shaft j
thus clamping the hub & between the shoulders of the shaft and the collar m,
(which collar m may he loose upon or suitably secured to shaft i) and the boss of the
wheel, when the said collar m is loose as shown. The cylinder is thus compelled
to rotate with the shaft when desired. The shaft is fitted at its upper end with a
screw-cap o, which tends to keep the wheel in place and relieve a portion of the strain on
the set-screw of the wheel n. The shaft is supported in the brackets or bearing-boxes
Fig. 6, and the shaft is reduced in diameter, as shown in Fig. 1, at its bearing-points, so
that the shaft i does not have any endwise movement. The inner ends of these shafis
are provided with worm-wheels t, which are driven by the worms P. These worms
are supported in suitable bearings, or by the hed-plate through which they pass, and
between this and the base-plate they are provided with worn-wheels P operated
secondary worms which are driven by the cone or conical polley ², which is
connected with its opposite come pulley by a cord or other suitable belt, the cone
pulley u being attached to the shaft of the driving-pulley y. By this arrangement a
slow movement is given to the cylinders, which movement can be varied by shifting
the belt on the cone-pulleys, and the speed is increased or diminished according as it
is desired to have the article to be burnished remain a greater or less time under the
burnishing-tools. The section P of the burnishing-shaft is made angular to prevent
its rotating, and it slides in the bracket or box p', which is, or may be provided with
a renewable bearing-sleeve. To the upper or outer end of this section, the section 7
is attached by a set-screw or otherwise, and to this section y any desired number of
burnishing-tools may be attached by collars and set screws as shown in Figs. 2, 3 and
4. The parts are tubular, and, as shown, the arms a are located within the tubular
portion. The arms are made to conform (by the springs acting upon the arms) to
the varying surfaces of spoons, forks and similar articles which are to be burnished
so that while the bowl and upper surface of the spoon or article is being burnished in
by

page_text: one holder or cylinder the back of the corresponding spoon or article may be
burnished in the holder or cylinder on the opposite side so that however varying the
surfaces may be, the movements of the burnishing tools will have corresponding
movements, and without giving any greater or additional pressure to projecting paris
of articles of irregular form, they can be properly burnished in all their parts, but it will
be readily understood that the arms, which carry the burnishing-tools, may fit on
the inside and the springs be located on the outside of the tubular arms e. which
gives a steadier support to the arms and a freer movement to the springs w.
For the purpose of preventing the arms c from getting entirely out of their
sockets, the armi e may be slotted, as shown at Fig. 2, and a limit pin or projection be
applied to the arm in proper position; but as the arms are always in the
same relation to the cylinders when in operative position, and the feed is from the
side, they cannot get out of place when limit devices are omitted.
The burnishing-wheels or tools in the outer ends of the arms are of the usual
construction, and they may be all alike, or they may be different, so that for knives or
other articles having handles of wood or other non-metellic material suitable burnishers
may be applied for burnishing or polishing such material, and the remaining
burnishers be adapted to different material. They are separately adjustable along the
section .7: so that they will work in their proper position, and a greater or less throw
or limit of movement may be given them by moving the wrist-pin in the slot
toward or from the centre of the crank-wheel t, and the position of all may be
changed by screwing the section in or out, so as to lengthen or shorten the distance
between the inner end of the pitman and the section p, which carries the section 4.
This change of position may be made at any time by simply unshiping the pitman
from the wrist-pin or the wheel and giving the screw-section a suitable number of
turns to obtain the desired position when the pitman is replaced. The groove t¹ is a
dovetailed groove, and the wrist-pin is attached to a suitable block sliding in said
groove, which may be provided with a set screw or other device to lock or hold it in
the desired position.
The
The liquid-reservoir B is supported by the standard or post d', and it is elevated
sufficiently to give a slight pressure in the tubes and it is provided with a tube or
pipe, el, having a stop or cut-off valve or plug, h. The pipe e is forked, and its
branches are located over the burnishing-tool, so that the drip from the faucets g
will be in the proper relation to the tools and the article being burnished.
tubes may be re-enforced by collars where the faucets gl pass through them, and
the upper side of the passage is screw-threaded, as shown in Fig. 7, full size. The
stems of the faucets are tapered to a point which extends below the tube and forms a
guide for properly directing the drip, which drip may be increased, diminished, or
cut off by turning the stem, as by turning it backward the screw portion of the
stem lifts it so as to increase the drip-space, and turning it forward diminishes or
closes the drip-space, so that the amount of drip can be easily regulated. The
pipes, instead of being forked from the pipe el, may lead direct from the reservoir,
and additional pipes leading to other machines may be connected with the
reservoir B. The liquid placed in the reservoir is such as is ordinarily used in
burnishing.
It will be understood that by the use of the hand-wheels either or both cylinders
can be loosened, and that when the friction-clutch is thrown off, the cylinder may be
revolved by hand in either direction, so as to enable the operator to discharge the
entire number of articles burnished and to refill the cylinder, if it is desired to so
operate the machine; but the motion of the machine is such that the burnished
articles may be taken out and fresh articles supplied without stopping the machine, so
that its operation may be continuous, if it is desired to operate it in this manner.
The preferable size for a cylinder is one which will hold forty-eight articles to be
burnished; but it is evident that the cylinders may be adapted to a greater or less
number, as the elastic bed-plate and the springs we will cause the burnishing-tools to
come in propor contact where the articles do not conform in line or shape to the
surfaces of the cylinder.

page_text: By this construction I obtain a simple and efficient burnishing-machine, which
can be operated either continuously or in any other manner, as may be desired,
which is simple in its construction and efficient in its action, and the movements and
operations are such that a number of machines can be operated by a single attendant,
and thereby greatly reduce the labour and cost heretofore required in burnishing
small articles.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I declare that what I claim is :-
1. The cylinder a and elastic covering c, adapted to receive articles to be
burnished, in combination with the band hand spring clamp-bars a substantially as
