Application November 11, 1933, Serial No. 697,678
4 Claims. (CI. 21—68)
The invention relates to baseball bats and more
particularly to an apparatus for treating the
same, and has for its objects to provide a base
ball bat impregnated with a suitable adhesive to
5 prevent separation of the adjacent woo‘d layers
10
With such objects in view, as well as other ad
vantages which may be incident to the use of
the improvements, the invention consists in the
apparatus and in the use of the parts and com
of the bat, as well as chipping, splintering or
binations hereinafter set forth and claimed, with
the understanding that the several necessary ele
checking of the outer wood layers, heretofore
ments constituting the same may be varied in
found to be prevalent in baseball bats as an inci
dent to the use thereof.
proportions and arrangement without departing
This application is a continuation in part of
our copending application, Serial No. 483,064,
?led Sept. 19, 1930, for Baseball bat, etc., now
Patent No, 1,936,579, issued Nov. 28, 1933.
A principal object of the invention is to pro
15 , vide a new and improved apparatus for individ
ually treating and thoroughly impregnating the
bats for the purpose described, while permitting
of variations of the treatment with regard to
individual bats, thereby obviating the necessity
of treating the bats uniformly without regard

no
for individual requirements.
A further object of the invention is to provide
an apparatus for impregnating baseball bats in
such manner that the entire cross sectional area
“ of the pore rings are impregnated for any de
sired extent along the bat barrel, and preferably
in one direction only, thereby insuring complete
induration of the area between adjacent layers
of wood ?ber without trapping or occluding the
air within said pore rings, the pressure of which
would otherwise result in certain portions of the
pore rings remaining free from impregnation.
A still further object is to provide an appa
ratus of the character described in which the
impregnating fluid containing an adhesive, to
gether with the air pressure for forcing the adhe
sive mixture throughout the pores of the bat,
are admitted simultaneously or coincidentally
from the nature and scope of the invention.
In order to make the invention more clearly
understood there are shown in the accompanying
drawings means for carrying the same into prac
tical effect, without limiting the improvements,
in their useful applications, to the particular con
structions which, for the purpose of explanation,
have been made the subject of illustration.

with a main line 3 ‘constituting a source of sup
ply of the treating material to the individual
tanks. A valve connection 4 is disposed on each
branch pipe 2 to regulate the flow of treating
?uid to the individual tanks. The treating, ma
terial in the desired state of fluidity is contained
within a main supply tank 5, the normal high
10 level of said treating material being indicated
at 5. The tank 5 has a ?lling opening ‘I normally
tightly closed by a ?ller cap 8. One end of the
supply tank is in communication with the pipe
line 3 which is also provided with a master con-'
trol valve 9. The supply tank is provided at
one end with a normally sealed closure 50 to per
mit access to the interior of the tank for the
purpose of clearing or renovating the same.’
An air compressor or pump is indicated at it
and communicates with an air'pressure tank H
by means of a pipe l2 having a control valve

interior of the tank H.
The treating material, preferably casein glue
or gelatin, is thoroughly admixed with water
and reduced to the desired state of ?uidity and

source connected to the pulley 15c.
this manner a ?uid and air tight chamber is
obtained in each tank i when the lower end of a
bat to be treated is inserted in said tank. Each 10
tank I is further preferably provided adjacent its
upper end with (a normally closed petcock or
valve 26 communicating with the interior of the
tank for releasing the accumulated pressure in
said tank after the bat has been treated and is
ready to be withdrawn. The opening of valve
26 also permits expulsion. of displaced air with
in the tank as the bat is inserted.
Each tank 5 is provided with an adjustable
clamping device generally indicated at 2'! for 20
removably maintaining the bats to be treated in
inserted position within said tank. As illustrated
each clamping member comprises a pair of sta
tionary upwardly extended strap members 21a
the lower ends of which are secured to the tank ‘I
and the upper ends of which are provided with a
series of spaced vertically aligned outwardly ex
tending projections or lugs 28. The clamping
member pro er consists of a horizontally disposed
guide plate or member 29 rigidly secured at its ii i)
opposite ends to 'a pair of downwardly extend
ing movable strap members 39 having a slid
ing or telescoping engagement with the station
ary strap members 2?. Suitable guides or bear

gasket 26 in turn clamped against the upper
surface of the packing by means of a cap mem
ber 25 having a ?uid and liquid tight threaded
connection 22 with the cylindrical wall of the
tank. A secure hermetic engagement is further
insured by providing a steel gasket or ring 2260
superposed upon a rubber or other ?exible gasket
ly provided with a semi-circular recess .36 of
sufficient diameter to receive the end of the
handle portion 37 of the bats 2d, yet preventing .

A central aperture 23 in each‘cap member 2! is
of’ suf?cient'diameter to permit the downward
insertion of bats of varying diameters within the
70 tank 5. The lower or'barrel ends of the bats 2%
to be treated are adapted to be inserted down
wardly into the tank through the apertures 23
in the upper cap members to a point appreciably
near but preferably spaced above the bottom
75 of the tank. The lower opening 25 of the ?exible
.he upper end Bio of each adjustable clamping
member is designed to rest upon the knob 38 or
plate projection 39 of the bat after the latter
has been inserted in the tank l and its handle
portion inserted laterally into the recess 35 of the
guide plate 2%. The clamp is then drawn down
wardly until the desired degree of insertion with
in the tank has been obtained. At this point
loop members or latches 49, loosely mounted on
the guide plate 29, are swung downwardly into
engagement with the proper lug or projection 28
to ?rmly lock or clamp the bat in position against
vertical'movement relative to the tank l. The
provision of a plurality of keepers or lugs 28 for
engagement with the loop members 43 renders
the apparatus ?exible for the purpose of accom
modating bats of various dimensions with the
assurance that a hat of“ any length may be readily
locked in engagement with the tank at the de
sired degree of insertion therein.
In Figure 6 a slightly modi?ed form of cham
ber or tank for the individual bats is illustrated.
Said chamber comprises a cylindrical tank la 75

having a downwardly and forwardly tapered im
pregnating chamber lb. A similarly tapered or
cone shaped rubber packing lo ?ts closely within
the impregnating chamber and is designed to
snugly and resiliently engage the end of the bat
the bats for the purposes of the invention. The
time of treatment varies according to the degree
of porosity, dryness and nature of the wood, as
well as the consistency of the fluid. In practical
operation it has been found that the time of
barrel after the latter has been inserted to the
treatment of the bats at a pressure of substan
tially 200 pounds per square inch in order to
thoroughly permeate the pores of the bat, re
quires about 11/2 minutes. (By a similar treat
ment at reduced pressure this period may be ex 10
tended to a maximum time of three-quarters of
an hour.) At the expiration of this time, the
glue or adhesive material in suspension may be
observed exuding from the bat barrels above
certain of the tanks l indicating that the portion
of the bat within such tank has been thoroughly
saturated. At this time the pressure is shut off
by closing the individual control valves 4 leading
to the tanks l. Pressure within each individual
tank I is relieved by opening the petcocks 26. 20
The clamps 2'! are then loosened and elevated

Communication with the branch pipes 2a in turn
communicating with the supply line So is afforded
10 by means of a threaded aperture 317 communi~
eating with the bottom of the impregnating
chamber. The described arrangement dispenses
with the upper and lower cap members for the
tank la and also requires the use of a somewhat
15 differently shaped flexible rubber packing
Ic.
In other respects the apparatus is substantially
as described with respect to the remaining ?g
ures of the drawings.
In the operation of the apparatus the impreg~
20 nating material, preferably casein glue in pow
dered form, or gelatin is mixed with water in
the mixer l5b to obtain the desired degree of ' to permit the bats to be tilted laterally from

barrel has been'found su?icient to properly treat

ate the pores of the wood of entrained air prior
to introducing the treating ?uid under pressure.
It has been found that the cells of the wood are

treatment any and all entraineclair. This is
permitted by enclosing only the portion of the
bat to be treated within the individual pressure
tanks l and leaving free and exposed the upper
portion of the bat topermit ‘the escape of en
trained'air under pressure applied from within
said tank.
This entrained air is or may be
chie?y present in the pores or spring growth of
the bat which is of appreciably greater porosity
10 than the adjacent cells of the bat strata, com
monly called the meat or substance of the wood.
The invention however contemplates the use of a
vacuum within the tanks Iprior to introducing
the impregnating ?uid, should such additional
step be advisable under certain conditions.
The described treatment is a decided advantage
over placing the entire‘bat within a sealed tank or
impregnating chamber for the reason. that in
the latter instance the ?uid under pressure is
forced into the pores of the bat adjacent the sur
face ‘thereof at a plurality of points along the
bat barrel, which frequently results in trapping
a portion of the air between the ?uid advancing
under pressure within a particular stratum ‘or
strata from opposed directions. This condition
would deter or prevent the thorough impregna~
tion of the bat barrel at the point where such
entrained air is trapped and which point is sub
ject to the greatest strain and use, thereby re~
30 quiring more thoroughpermeation for protection.
The removal of the tapered spur as at the end
of the bat barrel prior to the treatment effectu
ally aids the complete penetration of the impreg
nating ?uid throughout the center or core of the
bat barrel. The presence of such spur end 313
acts to prevent the impregnation of the ?uid at
this point and this is not so much because of the
additional material but for the reason that the
spur’marks of the lathe compress the wood at
40 the end of the billet to seal the pores thereby pre~
venting‘access of the glue to the bat at this area.
By treating the bats individually in the tanks
i in accordance with the invention above de
scribed varied and individual requirements may
be satisfactorily served as to certain bats, as it
may be desirable to effect a more thorough im~
pregnation in certain instances than in others
due to the material of which the bat is made and
the degree of porosity of the wood or for other
considerations.
In these respects theinvention
affords distinct advantages over treatment of a
for any desired portion of or along its entire
extent by varying the time of treatment and
the depth of the tanks l. The practice of the
invention as above described permits of very
rapid penetration of the wood thereby resulting
in economies in operation and increased produc
tion. The treatment does not discolor the wood
or otherwise render the same di?icult to stain or
?nishin any color.
Individual bat treatment 10
insures uniform penetration of the barrel portion
and permits of adjusting the degree and time of
penetration to accommodate bats having di?er
ent degrees of hardness. There is no core left
of untreated wood and a stronger and more solid
ly permeated barrel is obtained.
.

‘
It will be understood that when one set of
batsrhave been impregnated in the tank I and
removed and placed on the usual drying racks,
another set of bats is immediately placed and 2,0
locked individually within the tanks and the
proper control valves manipulated to permeate
and impregnate the bats with the adhesive in
accordance with the method above described.
This arrangement permits convenient and rapid 25
handling of the ‘bats to treat a considerable num
ber of ‘the same within a comparatively short
space of time. There is no soaking of the bats
with consequent serious gain in weight, and the
method is further attended by little or no waste 30
of impregnating material.
The submerging of the ?rst assortment of bats
to be treated in the empty tanks l and except
for a few minutes of treating, as to subsequent
assortments, reduces the possibility of swelling 35
to a minimum and enables the bats ordinarily to
be thoroughly and completely dried in seven
days. The swelling of the bats, a disadvantage
which is obviated by the-invention, causes en
largement of the grain which in theact of drying 40
would result in cracks due to uneven contraction
or expansion.
7
The penetration of the pores of the wood by
means of the glue renders the ?nished bat water
proof and not susceptible to moisture absorption. 45
This is an advantage for the reason that the
penetration of moisture softens the wood and
renders the bat incapable of driving the ballas
far as a dry-moisture-proofarticle.

portion of the bat barrel to illustrate the varying

material, these porous cells, indicated at A will 55

The invention presents further advantages
over existing methods in that the impregnating
fluid and air pressure are admitted simultane
ously to the treating chambers I, through a single
port 2 thereby dispensing with the necessity of
60 separate valves, tanks and connections for the
air and treating fluid respectively.
Due to the thorough and complete impregna

tion or" the bat ‘barrel including the core portion
thereof it is possible to store the treated bats
inde?nitely. When a bat of certain speci?ca
tions is required, which might necessitate an ap
preciable reduction in diameter, it is possible
to' turn down the barrel to any required diameter
without reaching a portion of the barrel which
has not ‘been impregnated.
_
In accordance with the present invention the
bat is impregnated from the bottom end only
through the grain to about 12 or 14 inches along
' the barrel.
This prevents any possibility of air
75 pockets left unpermeated. and. it will be further
be ?lled or lined with the material. With a sub
stantially heavy or thick solution the porous cells
B of smaller diameter will be substantially ?lled
with the impregnating material such as casein
glue or gelatin and this may be also true to a
considerable extent at least as to the porous cells
so
of intermediate orlarger diameter. When the
impregnating .?uid isof relatively thin consist
ency, such as one part of adhesive to eight parts
of water, only the walls of the porous cells of 65
larger diameter will be lined with the adhesive as
indicated at C in Fig. 13, This may alsorbe true
as to certain of the smaller porous cells B present
in the wood. Fig. 13 graphically illustrates that
the impregnating material does not necessarily 70
?ll the porous cells with adhesive with consequent
material increase of the weight of the bat, es
pecially when the adhesive contains a higher pro
portion of water or other mixing fluid. N everthe
