Improvements in Apparatus for Polishing Needles, Wire,
and the like.
We, LUDWIG BÜNDGENS and JOSEPH BÜNDGENS, of Aachen, in the Empire of
Germany, Machine Makers, 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 :-
The polishing machine shown in the accompanying drawings serves to rub or
abrade and polish needles and wires of all kinds, and the following are the details
of the same ;-
In the box a there are two oscillating rollers b of any desired shape in cross
section, the intervening space e between which simply serves to hold the needles
intended to be rubbed.
b
By drawing out the roller-shafts d the rollers 6 may be removed, to allow the
box a to be filled about one-tbird full of rows (laid side by side) of wire needles
and rubbing or polishing material. Thereupon the rollers bare restored to their
places and their shafts d are slipped in again; after which the needles or wires are
further laid in like manner until the rollers are covered over, to a corresponding
height. In order to hold the needles up and press them against the rollers b and
the walls of the box a, the latter is provided with a cover e formed in one or more
parts and pressed by springs g so that the shape of the box with its cover corresponds
to that of two hollow cylinders joined together side by side, in each of which one
of the rollers b rotates.
The cover e and box a are provided on both sides with notches for f¹ so that the
same by means of teeth, may engage with each other, and thus the cover e can form
no projecting edges in the box.
Through the reciprocating motion of the rollers the needles have a corresponding
rotary movement imparted to them whereby they rub against and polish each other.
The rollers may be actuated in any suitable manner, as e.g. by means of
mechanism, supported by the frame h, and comprising the driving-shaft i and crank
disc k, which latter, by means of the connecting rod actuates the lever arms m
connected with one of the rollers 6 and by means of the wheels n connected together,
causes the rollers to swing or oscillate to and fro.
Or by the use of ratchet wheels o and pawls p of which one is from time to time
released by the action of the cam q upon the lever r a gradual complete revolution
of the rollers b, over and above the to-and-fro swinging or oscillating motion thereof,
is obtained, whereby the underlying needles are brought uppermost, and the
uppermost, on the contrary, are brought down to the bottom of the box a which
has for its result a perfect and even polish and a thorough distribution of the
polishing materials.
If desired more than two rollers b may be arranged in each box a.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is ;-
1. A polishing machine for needles and wire comprising one two or more rollers
such as b located in a box such as a and surrounded with the articles to be rubbed
or abraded and polished and the material to be used for that purpose, and then
caused to oscillate substantially as described and illustrated in the accompanying
drawings.

page_text: 2. In the machine such as claimed in Claim 1 a rubbing box comprising a spring
controlled cover such as e and the box a so fitted together as to avoid by means of
teeth projecting edges in the inside of the box.
3. A modification of the machine claimed in Claim 1 wherein besides the
oscillation of the rollers b by the use of ratchet wheels and pawls such as op
whereof one set is from time to time rendered inoperative also a slow intermittent
complete rotary motion is imparted to the rollers substantially as and for the
purpose described and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete machine
for polishing needles wire and the like substantially as described and illustrated in
the accompanying drawings.
