PROVISIONAL SPECIFICATION.
Improvements in Scouring and Polishing Small Tooth Combs
and other Combs, and other Articles of Horn or Analogous
Materials.
We, JOHN SUTHERLAND Manager of Messrs. Elrick & Co. Ltd. Rosemount
Works, and WILLIAM SCOTT Engineer of 4 Caroline place, both in the town and
County of Aberdeen North Britain, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in scouring clatting and polishing small
tooth combs and other combs, and other articles of horn or analogous materials, and
has for its object to effect the operations by apparatus acting automatically, and so
dispense with the usual hand labor.
In carrying out my invention the buffs are mounted upon horizontal axes, the one
buff being immediately above the other, so that the comb or other article is operated
upon between the peripheries. In a position approximately at the level of the
junction of the two peripheries, we provide a table which is capable of revolving upon
a vertical axis, the said table is provided with four or other convenient number of
sliding holders convenient number of slide holders carrying the combs or other articles
to be operated upon, the said slides working in V slots, and the said slides are pushed
forward or outward to a position between the buffs, and withdrawn therefrom, under
the influence of a cam, keyed upon a horizontal spindle, mounted upon a bracket
immediately above the table, the said spindle being rotated by belt & pulley-We
cause the table to be intermittently rotated or partially rotated so as to bring each of
the four (or other number) of the holders carrying the combs, in a position in front
of the buffs, and when so brought into position the cam is arranged to push forward
the slide; the said slide being withdrawn by the action of a spiral spring or the
equivalent of the same; we find it convenient to actuate the slides through the
medium of a pivoted lever, the free extremity of which is caused to act against
the end of the slide, the cam bearing upon an antifriction roller mounted upon the
side of the lever.
The intermittent motion to be given to the table may be offected by a pawl acting
upon a ratchet collar keyed upon tho spindle carrying the table, the pawl being
actuated in any convenient manner such as by a rocking lever actuated from an
eccentric keyed upon a vertical spindle which is driven from the horizontal shaft,
herein before described as being driven by band and pulley through the medium of
bevel gearing.

We, JOHN SUTHERLAND of Messrs. C. G. Elrick & Co. Ltd. Rosemount Works,
Manager and WILLIAM SCOTT of 4 Caroline Place Engineer, both in the Town and
County of Aberdeen, North Britain, 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 which relates to improvements in scouring, and polishing small

page_text: tooth combs and other combs and other articles of horn or analogous materials has for
its object to effect by machinery what has hitherto been done by hand.
In order that our Invention may be readily understood and easily carried into effect
we will proceed to describe it with reference to the accompanying drawings, Figure 1,
sheet 1, of which is a side olevation, Figure 2, sheet 2, a plan and Figure 3, sheet 3,
an end elevation on a larger scale of our machine, Figure 4, sheet 1, sectional elevation,
and Figure 5, sheet 2, a plan of our slide or holder with tongs us when holding the
articles to the buffs.
In carrying out our Invention we employ an ordinary pair of scouring, clatting or
polishing buffs as required, the said buffs being mounted in suitable bearings which
are capable of vertical adjustment so as to enable the distance between the two faces
to be regulated as also to adjust in case of wear.
Immediately in front of the said buffs, we mount our improved machine, which
consists as follows:-
A, is a cast iron sole plate on to which is secured the cast iron standard B, which
carries a rotating table C, the said table being formed on the top end of the spindle C",
which works in suitable journals b, b, formed on bracket B. This table C, has
mounted on its top side a suitable number of slides or holders D, preferably five though
we may use any other convenient number, these slides or holders D, (as shown more
particularly in Figures 4, and 5), work in grooves d, formed in suitable brackets E,
either formed on or fixed to the table C, by suitable means, and provided with
openings e, on their undersides for allowing of suitable springs E, to work in, the one
end of each of the said springs being fastened to the said brackets as at e', the other
ends being fastened to the slides or holders D, as at e², the object of the springs E',
being for withdrawing the holders D, from the buffs when required. The pushing
forward of these slides or holders being effected by means of the lower end of a
swinging lever F, Figures 1, 2 and 3, which is operated upon by a suitably shaped
cam F, keyed on the one end of a horizontal cross shaft. F, carried in suitable
bearings, formed on the bracket G. This shaft having mounted at its other end
the driving pulleys H, as also a bevel or mitre spur wheel H, which works into
another bevel or mitre spur wheel H³, keyed on the top end of the upright shaft J,
which is carried in suitable bearings j, formed on the standard K, this standard having
also provision formed on it for supporting the top bracket G. The said shaft J, has
mounted on it near its lower end an eccentric L, with strap L', and rod L³, the end of
this rod L, being attached to the one end of a double lever M, carried by a pin or
stud m, the other end of this lever is fixed to the one end of a pawl N, which works
into a ratchet wheel N, keyed on spindle C, thus giving the necessary partial rotation
to the table C, and slides or holders D, the said pawl N, being kept in its proper
position at all times by means of the small spring n, and più n¹.
The slides or holders D, bave mounted on thein one or more pairs of tongs P,
(preferably two pairs on each slide,) for holding the combs or articles to be operated
upon, the said tongs being so arranged that each pair presents the article they hold to
a different part of the buffs' faces from that of the others, so as to cause an equal
wear of the buffs. And to allow of the said tongs to be opened, we employ a small
gradiant or quadrant Q, carried in a suitable bracket fixed to or formed on the
standard B, underneath the table C. This gradiant Q, being for the purpose of
raising the pins R, by means of their lower ends rubbing along the top of the gradiant,
these pins it, being mounted immediately underneath the top arm of each pair of
tongs, so that on the pins being raised they also open the tongs and allow the articles
to he withdrawn or put in, or if desired for closing the tongs gradually while the
articles are being placed therein we may mount another quadrant S, which is capable
of being raised or lowered and is carried in a suitable bracket S', fixed to or formed
on the standard B, this bracket also carries a small rocking shaft or pin s, upon which
is mounted a suitable cam T, and lever U, the end of which is attached to the one end
of a connecting rod V, the other end of this rod being again attached to the one
arm of the lever M, at v, so that on this arm of the lever M, being moved backwards

page_text: or away from the table, the cam T, allows the quadrant S, to be lowered and thus
allow of the tongs being closed by the springs W, which are mounted on the top of
the slides or holders D.
The working of the machine being as follows; suppose the various parts are in the
positions shown in the drawings, and the power is applied to driving pulleys H, the
shaft F, is caused to rotate along with the cam F1, thus causing the lever F, to be
pushed outwards and with it the slide and tongs marked 1, thus presenting the articles
in the tongs between the faces of the buffs, while this is being done the shaft J, is
being rotated and with it the eccentric I, which causes the lever M, to pull the pawl N,
backwards ready for its next forward stroke, this movement of the lever M, also
causing the quadrant S, to he lowered by means of the cain T, thus gradually closing
Immediately
the tougs on slide marked 4, after the articles have been placed therein.
the cam F, passes its outmost point the lever F is pulled back by means of the small
spring, the slide with tongs marked 1, being thus allowed to be pulled away from
the buffs by means of the spring E', after this has taken place the paw! N, begins to
push the ratchet wheel N', partly round, and with it the table, slides and tongs, till the
slide and tongs marked 5, take up the same position as those marked 1, at the
same time the lever M, which operates the pawl N, by means of the eccentric L,
causes the cam T, to partially rotate and thus raise the quadrant S, ready for the
ends of the pins R, which have been raised while passing along the gradiant Q,
after which the motions are repeated.
The buffs and the machine may be driven either separately or jointly by any
suitable means.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same. is to be performed we declare that what we
claim is :-
First. In scouring, clatting and polishing combs and other articles of horn and
analogous materials, the general arrangement and construction of our machine to
