Letters Patent No. 97,384, dated November 30, 1869.
IMPROVEMENT IN FEED-correas.
The Schedule referred to in these Lettera Patent and making part of the same.
To all whom it'may concern:
Beit known that I, WARREN Genn, of Peekskill,
' in the county of Westchester, and State of New York, i have invented certain new and useful Improvements cutter, of a slotted knife-shaft, constructed with a space between the rings that hold the knives' in place,
and the journal-boxes, in which the shaft runs, so that when the rings are released, they can be moved on the shaft, so as to release .the knives,.in order that they may be removed or replaced without removing the shaft or journal-boxes.
To enable others skilled in the art to which my invention appertains, to make and use the same, I will now describe its construction and operation.
In the accompanying drawings- 'A represents the cutting-shaft, provided with spiral slots around its surface, into which are placed the spiralknives a a, as seen'in iig; 2.
These knives are held in place by caps or rings b b passing around the ends of the knives.
`The cutting-shaft A is pivoted inthe metal journalboxesl d d, secured to the forward end of the frame E.
It will be vseen that they knives a a do not extend' the'whole length of the shaft, butthat there is a space between the ends of the knives and the journal-boxes d d, to allow the rings b b, when detached from the knives, to move on the shaft, which allows the knives to be removed or replaced without removing the shaft. A
I usually make the cutting-shaft A of what is known as malleable-iron castings, as this is much stouter than ordinary castings.
B represents the pressure-cylinder, made of any suitable material and size, and pivoted above the cut ting-shaft A, in journal-boxes d d', secured to the forward end of the frame EL G is a cog-wheel, attached to one end of the cylinattached to the end of the shaft A.
On the other end of shaft A is secured the drivewheel D.'
F represents the feed-box secured to theupper end of the frame E, as seen in fig. 1.
f is the forward end of the bottom of the feed-box, and is hinged to the remainder of the bottom, as seen der B, and gearing into a corresponding ogwheel, C',
i in fig. 1,.
g is a spring, one end of which is attached to the frame E and the other end resting against the hinged bottom f, so as to allow the -feed to enter the cuttingshaft in a compact state.
h h, are screws, for adjusting the pressure-cylinders.
In operating machines -of this classit will often happen that the knife will' be placedFn in the machine in a reversed position, that is, with the bevel side forward) This causes the machine to work imperfectly and hard, besides frequently damaging the machine.
To avoid this diiiculty, I make the ends of the shaft of different diameters, anduse caps or rings of unequal diameter on their inside, and the knives being notched accordingly, they cannot he reversed and put in the machine without recutting the notch on the knife.
I iaving thus described my invention,
Y What I claim as new, and desire to secure by Let'-` ters Patent, is l l. Inthe construction -of feed cutters, a slotted knife shaft, constructed with a space between the rings or caps b b, that hold the knives a a a in place, and the journal-boxes d 1,iu which the shaft runs, so when the rings, or either of them are released, they can be moved onthe shaft, so as to release the knives, so they can )be removed or replaced without removing the shaft or journal-boxes, substantially as described.
2. A slotted knife-shaft, provided with knives bevelled on the back side, and provided with caps or rings of unequal diameter, so the knives cannot be reversed, substantially as described. In testimony that I claim the foregoing as my own,
I aiix my signature, in presence of two witnesses.
