Improvements in Cork Cutting Machines.
I, HENRY WEINZ, of 2637 Penn Avenue, in the City of Pittsburg, State of
Pennyslvania, United States of America, Merchant, 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 relates to certain new and useful improvements in Cork Cutting
Machines, and the object thereof is to provide a machine that may be operated
without employing skilled labor and also make a complete tapered cork at one
operation, as well as effect a saving in the cork.
In describing the invention in detail, reference is had to the accompanying
drawings forming a part of this specification, and wherein like numerals designate
similar parts throughout the several views in which :-
Fig. 1, is a plan view of my improved cork cutting machine, and as it would appear
when on its forward stroke.
Fig. 2, is a side view of the same partly shown in section and as it would appear
when on its backward stroke.
Figs. 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 are enlarged views of various detail parts of
the machine, some of which are partly shown in section.
Reference to the drawings for the details of the machine the numeral 1 designates
the bed plate, which is provided with the upright standards 2, 3, 4, and 5 which have
suitable bearings formed thereon and are provided with the caps 7, 8, 9, 10, 11, 12
and 13. The main shaft 14 is loosely fitted within the bearings of the said
standards 2 and 5 and upon this shaft is secured the loose pulley 15, tight pulley 16,
gear wheel 17 and crank 18 the shaft 19 which is loosely fitted within similar
bearings upon the said standards has secured thereto the gear pinion 20 and bevel
gear wheel 21, the said gear pinion 20 is adapted to mesh or operate with the said
gear wheel 17.
The shaft 22 which is loosely fitted within the bearings of the standards 3 and 4
has secured thereto the bevel pinion wheel 23 and gear wheel 24, the said bevel
pinion wheel is adapted to mesh or operate with the said bevel wheel 21.
Secured to the standard 4 and cap 10, is the hollow sleeve 25, which has suitable
collars formed or secured thereto at intervals as shown. Loosely fitted within the said
sleeve 25 and the bearing of standard 3 is the hollow shaft 26, which has a thread
A hollow
formed upon its rear end and has the spider 27 secured to its forward end.
coupling 28 is loosely fitted over the threaded end of the said hollow shaft 26, and is
held in place by the jamnuts 29 and 291. A link 18 is loosely connected to the
said coupling 28 by a pin 30 at one of its ends and is connected at its opposite
end by the pin 31, to the crank 18. The pulley wheel 32 has the hollow tubular
portion 321 formed thereon and is fitted over the said hollow shaft 26 and between
the standards 3 and 4. A key 33 is secured or formed within the said tubular portion
of the pulley wheel 32 and projects down into a key way 34, which is formed within
and extends along the hollow shaft 26, so that the said shaft may have a horizontal
movement during the revolving of the same by the wheels, 41 is a gear pinion
secured to the said tubular portion 32¹ of the pulley wheel 32 and meshes with the

page_text: gear wheel 24, a loose pulley 42 is also fitted upon the said tubular portion. The
guide box holder 35 is loosely mounted upon the stationary sleeve 25 and has the
outwardly projecting lugs 36 and brackets 37 formed thereon.
Pivotly connected between the said lugs 36 are the guide boxes 38, which are each
provided with an opening into which are loosely fitted the rods 39. The said guide
boxes are adapted to be inclined to any suitable angle and secured when adjusted by
the screws 40 and 40¹. Formed upon the ends of the said rods 39 are the hollow
boxes 43 which have the slide blocks 44 loosely fitted therein and the screws 45 are
arranged at each end of the said boxes so that the slide blocks may be adjusted and
held in place.
Pivoted within the said slide blocks are the ends of the arms 46,
which are also pivoted at about their middle within the slide boxes 47 of the spider 27,
the said slide boxes 47 are capable of being adjusted by means of the screws 48. To
the forward ends of the arms 46 are secured the knife holders 49, which are provided
with the bushings 50 and 501 into which are fitted the knives 51, which are held
secure therein by the set screws 52. A bracket 53 is secured to the standard 5 and
has loosely fitted within its upper extremity the rod 54 which has a thread upon that
end whereby it may be adjustably held to the said bracket by the jam nuts 55 and 551
the said rod 54, is stationary and extends through the hollow shaft 26 and projects
out even with the ends of the knives when the machine is on its back stroke as
shown at Fig. 2.
Secured to the bed plate and in front of the knives is the upwardly extended
frame 56, having the adjustable frame 57 attached thereto and upon which the cork
is placed or held against when in the act of cutting out the corks.
In operating the machine, power applied to either of the tight pulleys 16 and 32
but preferably the former, and when in operation the crank 181 on its backward
movement forces the knives to gradually open (as shown at Fig. 2) by drawing the
shaft 26 backward the length of the crank stroke, and the said shaft during all times
is revolving as well as the spider 27, and the other mechanism including the guide
box holder, and when the knives are in their backward position, the cork board is
then placed in position upon the frame 57 in front of the knives and when the device
is on its forward stroke the revolving knives gradually advance into the cork board
and close, thereby cutting a tapered cork (large end first) and when on the next
backward stroke the stationary rod 54 forces the completed cork out from between the
knives. A graduated scale is arranged as shown upon the ends of the guide boxes
and the brackets at the end of the guide box holder so that they may all be adjusted
alike.
In order to cut corks of various sizes and tapers the arms 46 are adjusted at their
pivoted points within the spider 27, and boxes 43 upon the rods 39, as described in
detail, as well as adjusting the guide boxes 38 by the screws 40 and 40' and the
throw of the crank may be adjusted by means of the screw pin 31 of the crank and
the coupling 28 and jam nuts 29 and 29¹ upon that end of the hollow shaft 26.
