Invention of "AN IMPROVED FEED MOTION APPLICABLE TO MACHINERY EM-.
PLOYED IN CARD-TEETH-MAKING, CARD-SETTING, PIN-MAKING, AND OTHER
SIMILAR MACHINERY." A communication from abroad by Conrad Burkhard, of
Reichenberg. Austria.

PROVISIONAL SPECIFICATION left by the said Charles Walther at the Office
of the Commissioners of Patents on the 13th February 1878.
CHARLES WALTHER, of the City of Manchester. "AN IMPROVED FEED MOTION
APPLICABLE TO 'MACHINERY EMPLOYED IN CARD-TEETH-MAKING, CARD-SETTING,
PIN-MAKING, AND OTHER SIMILAR MACHINERY." A communication from abroad by
Conrad Burkhard, of Reichenberg, Austria.
This Invention consists in mounting a bolt or tongue on the feed lever so as to
receive its gripping motion upon the wire, being fed by means of a coil or other
suitable spring, and its releasing motion by a trigger finger, as herein-after
described. The extremity of this bolt or finger presses on to a pin or plate affixed
upon the feed lever, thereby firmly holding for the time being the wire which passes
between, and releasing the same when the feed lever takes its backward movement.
Motion is coinmunicated in the ordinary manner to the feed lever, and the trigger
finger herein-before mentioned is actuated by an eccentric or cam affixed upon the
driving shaft, the periphery or outside of which cam or eccentric is so formed as to
draw back the trigger finger by means of a connecting rod, and thus at the same
instant to draw back the bolt or tongue herein-before mentioned when the feed
lever is taking its backward movement, whilst the spring is free to act upon the
bolt or tongue and to grip the wire when the feed lever is taking its forward
motion..

CHARLES WALTHER, of the City of Manchester. "AN IMPROVED FEED MOTION
APPLICABLE TO MACHINERY EMPLOYED IN CARD-TEETH-MAKING, CARD-SETTING,
PIN-MAKING, AND OTHER SIMILAR MACHINERY." A communication from abroad by
Conrad Burkhard, of Reichenberg, Austria.
This Invention consists in mounting a bolt or tongue on the feed lever of wire
feeding machinery so as to grip the wire and draw it forward whilst the lever is
advancing in one direction by means of a coil or other suitable spring, and to
release the wire by a trigger finger when the feed lever is receding in the other
direction, the feed motion thus produced being applicable to the purposes above
mentioned.
On the accompanying Drawing the same letters of reference are employed to
indicate the same parts in the several views, and which I will now proceed to
describe.
Fig. 1 is a plan, and Fig. 2 a side view of a feed lever having my improvements
applied thereto.
A is the feed lever, the shorter arm of which rests against and is actuated by the
cam B carried by the shaft C in the ordinary manner. This feed lever is provided
with a long bearing A', which is bored out to fit accurately upon the pin or stud D,
and is further steadied in position by means of the washer D' and nut D2, which
latter screws on to the screw D³ formed upon the upper extremity of the stud D.
E is the tongue or bolt, which constitutes the feature of novelty in this Invention,
and is arranged to slide to and fro on the lever A by one extremity passing through
the cranked part of the lever A, as illustrated, and being embraced at or near the
other extremity by the metallic strap F. This tongue or bolt has a constant
tendency imparted to it to press up against the pin G by the action of the spiral
extension spring H, and thus the wire I, which passes between this pin and the
front extremity of the tongue or bolt E, is gripped and carried forward with the
feed lever in one direction. J is a trigger finger mounted upon the fixed pivot or
stud J, and having its finger resting upon the boss E' projecting from the tongue
or bolt, and connected at the other end, as illustrated, to a connecting link K, which
carries a friction bowl L resting against an eccentric M affixed upon the driving
shaft C.
The action of this wire feeding motion is as follows:-When the feed lever A is
advancing in the direction of the arrow the tongue or bolt E grips the wire I by
the action of the spring H, and draws or feeds such wire forward along with it, the
wire passing on through the wire guide N; but as soon as the feed lever commences
to retire again, the eccentric M is so "timed" upon the shaft C. as to push out the
link K, and thus the trigger J is caused to pull back the bolt or tongue E, and to
release the wire until the feed lever A again commences to advance, by which time
the eccentric M permits the spring H to resume full control of the bolt or tongue
and the wire I is once more gripped and carried forward.
Having thus particularly described and ascertained the nature of the said In-
vention, together with the best methods with which I am acquainted for carrying
the same into practical effect, I wish it to be understood that I do not confine
myself to the precise details, relative proportions, or dimensions of the various parts
of the improved feeding apparatus herein-before described, and illustrated on the
accompanying Drawing, as the same may be considerably varied without departing
from the Invention, but that I claim the use and application of the tongue or bolt E

page_text: when mounted and operated, substantially as and for the purposes herein-before
described, and illustrated on the accompanying Drawing.
In witness whereof, I, the said Charles Walther, have hereunto set my hand
and seal, this 9th day of August, in the year of our Lord 1878.
CHARLES WALTHER. (L.S.)
