William A. Sessoms, Bonifay, Fla.
Application September 17, 1937, Serial No. 164,410
11 Claims. (Cl. 30-121)
This invention relates to turpentine hacks and
pullers and more particularly to improvements
therein whereby such tools may be used more
Í effectively in the hands of unskilled persons per
ß4 mitting successive cuts to be made having uni
form depth and thickness.
This application is a continuation in part of
my application Serial No. 114,706, filed Decem
ber 7, 1936 and issued Oct. 19, 1937 as Patent No.
I0' 2,096,384.
In the use of a turpentine hack and puller, it
is advantageous to` have a form of tool which
may be readily operated by unskilled hands so as
to obtain with certainty cuts of proper dimen
1‘5'7' sions on a tree so that the life for the operative
period of the tree is increased and the yield of
tured at a lower cost than the forms as shown
and described in the said application by which
increased accuracy of the cutting operation is
obtained.
With these and other objects in View the in 5
vention comprises the various features herein
after more fully described and particularly de
ñned in the claims.
The invention is illustrated in its preferred and
modified forms in the accompanying drawings,

depth of cut.
Another object of the invention is to provide a
form of turpentine tool having an elongated
30= guide member which is readily demountable to
permit sharpening of' the knife member.
Another object of the invention is to provide a
form of adjustable guide in connection with a
turpentine tool by which adjustment of the guide
35= can be made with variations in the curvature of
the cutting edge of the knife member so as to
obtain equal cuts in depth and thickness on both
the left and right cuts on the face of the tree.
Another object of the invention is to provide a
40 form of adjustable guide to provide for a range

ameter than would be otherwise necessary for
obtaining the same size of cut.
Another object of the invention is to provide a
form of turpentine tool having a simplified con
50 struction which may be more easily manufac
tured than the forms heretofore developed, as
illustrated and described in the patent above re
ferred to.
Another object of the invention is to provide a
55. form of turpentine tool which may be manufac
ably held. The body portion 8 of the turpentine
Integrally connected to the body portion ß is
a head or enlarged portion IG in which is a groove
or channel IB in which the shank 20 of a knife
member 22 may be rigidly held. In order to
fasten the knife member in place, an opening 24
is preferably provided in` the shank of they knife
member and an opening 26 having an internal
screw thread is provided in the head I6, a stud
bolt 28 being provided to securely hold the knife
member in place.
The blade portion 23 of the knife member is
22
2,129,790
preferably made in the form of a loop positioned
symmetrically with respect to the body portion 8
of the tool, the edges 2l and 29 of the knife
member being sharpened to provide cutting edges
for the tool.

streak. Furthermore, if this construction were
used with a ñxed guide member, later cuts would
be shallower than the ñrst cut for the reason that
in the later cuts the guide edge 35 would con

tached on either side of the body portion of the
tool. The knife member may have a cutting
edge on both the forward and rear face of the
knife so as to be reversible in position in the
channels I8 and I9.
In order to guide the cutting edge of the tool
during a cutting stroke, an elongated rectilinear
guide member 3S is provided, the guide member
being preferably mounted in a substantially
V-shaped seat 32 having side members 34 and 36
20 carrying suitable stop members 38 and 40 respec
tively by which adjustment in the lateral move
ment of the guide to either side of the knife
member 22 may be obtained.
The stop members, by which the extent of the
25 swinging or lateral movement of the guide mem
ber is determined, may comprise set screws or
the like which may be held in any given or set
position by means of lock washers 42 and 44,
although any equivalent means adapted to limit
30 the lateral movement of the guide member to any
desired amount may be employed.
In order to suitably hold the guide member 3Q
in place in the V-shaped member, the lower edge
3| of the guide member is preferably cylindrical
35 in form so as to fit a corresponding cylindrical
opening S3 at the base or bottom of the V-shaped
member, whereby the guide member 30 may be
readily mounted or placed in position by sliding
the member inwardly in the direction of the knife
blade until the rear end ofthe cylinder engages
the wall portion or stop 46. The forward end
of the guide member, may be held in place by
means of a spring member 48 which abuts the
forward end of the cylindrical part 3| and is
connected to the body member by means of rivets
5G or other suitable fastening means.
The guide member 3i) may be readily removed
from the seat member 32 by depressing the spring
member 48 and withdrawing the guide member
from the cylindrical seat 33 in the V-shaped
member 32.
’
The upper portion 35 of guide member 30 may
also be cylindrical in form so that, in the use of
the tool, the upper rectilinear portion or element
55 ofthe surface thereof will contact the face of a
tree during the cutting stroke, and a lateral rec
tilinear portion or element of the surface of the
cylinder which is uppermost during use of the
tool will contact with the under surface of the
60 last formed streak or cut so as to guide the tool
and assure a cut of uniform depth and thickness.
By the term “depth” is generally understood the
distance of a cut into the sap wood of the tree,
while by the term “thickness” is understood the
65 distance or height of a cut up the tree, corre
spending to the thickness of a streak.
It may be explained in connection with the
form of device illustrated in Figs. 1 and 3 of the
drawings, that if the guide member were fixed in
the position indicated in full lines in Fig. 3 of
the drawings, the tool would have to be turned
a very considerable amount in order to obtain a
cut with the guide edge 35 against the face of the
tree, and the streak would slope upwardly pro
75 ducing what is known as a slab streak, which is
tact with an outwardly curved surface.
As the
subsequent cuts would be made, the tool would
By the use of the form of tool in which the 10
guide member may be moved laterally so as to
‘be positioned slightly to one side of the knife
member, as indicated in dotted lines in Fig. 3
of the drawings, the knife member is guided by
the guide member so as to make progressive cuts
of the same depth into the sap wood.
By the use of a shifting or laterally movable
guide member to be shifted or moved from one
side of the body member to the other in changing
the cutting stroke from one side of the face of 20
a tree to the other, a smaller or narrower knife
blade than would be necessary for obtaining cuts
of a given size or thickness, may be employed.
This construction has the advantage furthermore
that the force employed in the cutting stroke is 25
more directly in line with the cutting edge so
that the lost component of force in making the
cutting stroke is very appreciably less, and there
is less tendency to lose a stroke because of en
countering knots, knurls or variations in hard 30
ness of the bark and sap wood to be cut through
during the cutting strokes.
Instead of the form of guide member as illus
trated in Figs. l and 3, I may employ a modiñed
form as shown in Figs. 4 and 5 of the drawings 35
having a lower cylindrical portion 52 adaptedto
ñt the hollow cylindrical opening 33 of the
V-shaped holding member 32, a central body por
tion 54 and an upper guide portion 56 to which
is connected the outwardly extending fins or
rectilinear guide edges 58 and 6€) which extend
upwardly and outwardly preferably at an angle
of substantially 45° with the central portion 56.
During use of the tool in making a cutting stroke,
one of the lateral guide edges or extensions 53 or 45
60 rides on the under surface of the last cut
streak so as to guide the tool and to determine
the thickness of the cut in making the next
streak.
The central extension or edge member 56 rides, 50
during a cutting stroke, on the face of the tree
and serves to guide the tool during the stroke to
determine the depth of the cut into the sap wood.
It will be understood that the form of the guide
member may bewaried in form as desired to ac
complish the desired purpose in guiding the tool
without departing from the invention as defined
in the claims.
The form of knife member 22 and mounting
therefor is illustrated in its preferred form in 60
Figs. l and 2 of the drawings, by which the cut
ting curvilinear edge of the knife is distributed
equally and symmetrically on each side of the
central plane of the body member 2 so as to pro
vide substantially the same form and character 65
of cut on each side of the face of a tree.
It will be understood however that in the
manufacture of the knife blades, a considerable
variation occurs and in exceptional cases the edge
portions of the blade are not symmetrical with
respect to the shank of the knife member. In
these cases the stops limiting the lateral move
ment of the guide member in each side of the tool
may be adjusted so that the cuts obtained with
3
2,129,790 .
the tool on each side of the face of the tree will
be substantially the same.
If desired a central opening or slot through
the body portion 4 of the tool may be employed
for mounting the knife member as is illustrated
in connection with Fig. 9, hereinafter more fully
described, or two single knife members may be
used if desired of the form illustrated more par
ticularly in Figs. 8 and ,l0 of the drawings in
connection with a modified form of the device in
which a chip catcher attachment is employed.
Referring to Figs. 6 to 10 ofthe drawings, an
improved form of turpentine tool is illustrated
which is similar in form to that shown and de
, scribed in connection with Figs. 1 to l1 inclusive
of my copending application Serial No. 114,706
Patent No. 2,096,384, above referred to.
In this improved form of the invention a slot
'Hl is provided in the body portion of the tool to
20 permit mounting separate knife members l2 and
‘M of similar form so as to be symmetrically ar
ranged when mounted in place in the body mem
ber.
In order to> suitably hold the knives in proper
25 spaced relation, a wedge member 16 is preferably
provided which is adapted to flt into the exten
sions 'i8 and 80 of the slot 'l0 to rigidly hold the
blade members in place.
.
In order to catch the chips as they are cut dur
30 ing a stroke to prevent the chips falling into the
turpentine cup, a rear tray or chip catcher 82 is
detachably provided at the rear end of the tool
and a forward removable tray or chip catcher 84
is provided at the upper or forward end of the
35 tool.
The rear tray 82 is preferably open at its for
ward end so as to permit chips or pieces of wood
to fall or slide along the tray and are held in the
tray by means of retaining walls or sides 86, 38
40 and by the rear wall or transverse retainer wall
Q0 which is preferably bent forwardly to form
a pocket 92 to hold the chips during a cutting
stroke. The transverse wall member 90 may be
located if desired at an intermediate portion of
45 the tray instead of at the rear end thereof.
The rear tray member 82 is also preferably pro`~
vided with lateral rectilinear guide members 94
and 96 which serve to guide the tool on the face
of the tree during cutting strokes on each side
50
of the face.
'
Upstanding rectilinear members or projecting
edges 68 and 99, are also preferably provided at
the upper portions of the side walls 36 and 8B
respectively, which serve to guide the tool during
55 a cutting stroke under the shoulder or cut surface
of the last-cut streak to obtain the desired pre~
determined thickness of cut.
`
The tray member 82 is preferably mounted so
as to be removable Vand adjustable in position
60 with reference to the cutting edge of the knife
member in a manner similar to the corresponding
adjustable guide member as described in my pat
ent above referred to.
Referring now to the forward chip catcher or
The vforward end of the tray is preferably bent
up so as `to form a forward retaining wall W6
which prevents the chips from flying forward
out of the tray, the wall being sloped forwardly
so‘that as the forward end of the tool is released
or turned downwardly after a stroke is completed,
the chips in the tray will fall to the ground.
In the portion of the tray immediately under
the knife members ‘l2 and ill, I preferably provide
an elongated slot H0 which registers with the 10
slot 1i), so that the wedge member ‘i6 projects
therethrough and may readily be forced out of
engagement with the knife members by striking
the projecting portion of the wedge member.`
It will be understood that in the operation of 115>
the turpentine tool, the chips are released from
the cutting edge of the knife member in a direc
tion toward the forward end of the tool into the
tray 84 and in any sudden jar or false stroke of
the tool the wings lilll, liiß serve to hold the chips 20'
in the tray and prevent them from falling into
the turpentine cup to cause discoloration of the
turpentine gum.
`
The manner in which parts of the device may
be attached and the manner in which the tool and
parts thereof operate are believed to be clear from
the drawings in connection with the above de
scription and from the specification of my Patent
No. 2,096,384 in which .the parts not particularly
referred to herein are fully described.
It will be understood that modifications or var
iations may be made in the improved form of the
device of my invention as shown and described,
without departing from the spirit or scope of the
invention as defined in the claims.`
