Improvements in Machines for Pouncing Hat-bodies.
I, GEORGE FREDLRICK LARKIN, of No 187, Broad Street, in the City of
Newark, County of Essex, and State of New Jersey, United States of America,
Manufacturer, 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 has ieterence to improvements in hat-pouncing machines, and
the object of the invention is to provide a machine of this geneial class, which
shall be very simple, and of a compact and effective construction, and which 18
especially adapted for the pouncing, sheating and finishing of hat-bodies, as well
as the lung of the hat-body after the same has been pounced
Heretofore hat-bodies have been pounced by the application of a granular
material, such as sand or emery, applied to the periphery of a rotary roll, or in
the case of crown pouncing, to the flat surface of a revolving disc or plate, which
18 brought against the hat-body on the evolving hat-block of the machine
Several objections are found to exist in the employment of such roll or disc,
provided with the granular material, the more serious objection being, that the
operator in bringing the granular surface of the 1oll or disc against the hat-body
may do so with greater pressure than necessary, thereby causing great heat due
to friction, which has a damaging effect upon the hat-body, and if not entirely
iuining the hat-body, giving the same a dingy and dull appearance, or, owing
to the hard material of which the 1oll or disc is made, the surface of the hat-
body will become unevenly pounced
My invention therefore has for its principal object to overcome these objectionable
features, by producing a machine for pouncing, sheating or finishing hat-bodies,
having a mechanism for applying to the surface of the hat-body, a moving granular
surface, in the nature of a flexible and endless belt, whereby a soft, even and
elegant finish of the surface of the hat-body will be the final result.
With these several objects in view, the invention consists in the novel con-
struction of hat-pouncing, shearing on finishing machine hereinafter fully set
forth, and, also, in the novel arrangements and combinations of the several parts,
all of which will be more fully described in the accompanying specification and
finally embodied in the clauses of the claim
The invention 18 clearly illustrated in the accompanying diawings, in which
Figure 11s a perspective view of the complete hat-pouncing machine, to which
the pouncing attachment embodying the principles of my present invention are
applied
Figure 2 is a plan view of the pouncing attachment, on an enlarged scale,
and Figure 3 is a side view of the same

Similar letters of reference are employed in all of the above described views,
to indicate corresponding parts.
In said drawings, A indicates a suitable machine-frame, comprising a table a

page_text: and supports a¹ and a². In suitable beaungs in the supports a, at the back, is
a shaft on which there is a loose pulley 6 and a fast driving pulley 6, and
63 18 a fork connected with a 1od b and a foot-piece 6, for forcing the diving
belt from the loose pulley b¹ upon the fixed pulley b³, or vice versa In suitable
bearings in the supports a' is the usual form of vertical shaft a' operated from
the belt 66 connected with the wheel on the shaft b, and at is the usual form
of foot lever for causing said shaft a to move vertically in its bearings, as will
be understood from an inspection of Figure 1
Said shaft extends through a table and has a hat-block thereon, on which
the hat-body to be pounced is secured in the usual manner
Secured upon the top of the standard or support a² is a yoke oi fiame e having
a beaning and arranged in sand bearing is a stem which 18 10tatively
airanged and secured in a hub of an upper yoke or frame c. The upwardly
extending arms of said voke or fiame e' have suitable beatings in which there
is a shaft 6 On said shaft is a pulley-wheel cover
which passes
a belt driven from a wheel 68 on the shaft b, as clearly illustrated in Figure 1.
Said upper frame or voke c is thus rotative horizontally in relation to the lower
frame on yoke e Pivoted upon
the shaft are the bearings d' of a yoke or
U-shaped frame d, to which is pivotally attached, in a bearing portion d³,
or bar f.
a lod
Said od or bar f is connected at its forward end with the hat-pouncing,
shearing or finishing attachment E, the same normally resting in the forked
end of a standard on the table a of the machine Said U-shaped frame d
has a rearwardly extending arm or 1od d³ on which there is a weight d acting as
a counter-balance to the weight of the attachment E, and facilitating the handling
of the same by the workman, while the machine is in operation
The said attachment E, which is more clearly illustrated in Figures 2, 3, 4 and
b, consists, essentially, of a frame e having a sciew-threaded socket e¹ for attaching
it on the screw-threaded end f¹ of the rod or bat f, as will be seen fiom Figure 4.
In the opposite end of said frame e 19 a similar screw-threaded socket e³,
into which is sciewed the end of a suitable handle e Said frame e
has suitable webs e and ef, connecting the longitudinal side-pieces e, whereby
certain open spaces and e' are formed in said fiame e In suitable bearing-
portions eo in the sides e, contiguous to the open space, 18 operatively secured
a pin or small shaft having a grooved or other suitable driving wheel hover
which passes a belt, said helt being operatively aanged over a driving wheel
or pulley on the shaft herein-above mentioned. On one side of the frame e
and secured directly on the projecting end of said pin or shaft h is a pulley-
wheel
Slidably arranged in the open spaces em the sides of the frame e, and
contiguous to the open space e, is a slide or block having a finger-piece or
handle projecting from one side of the said frame e, and a pin projecting
from the opposite side of the said fiame e, said pin 72 having a pulley loosely,
but operatively ananged thereon, said pulley being in alignment with the
pulley on the pin or shaft h, and a pouncing, shearing or finishing belt z
being arranged over said pulleys h³ and, the same being set in motion by the
pulley which is driven from the diving wheel h¹ and its belt h2, when the
operator has set the machine in motion
2
In order that the slide or block 18 operatively retained to slide back and forth
in the open space eli, as may be necessary, to keep the belt k taut and permit of
its yielding contact with the surface of the hat-body to be operated upon, said
slide or block has a pair of guide-arms and 2 which extend on opposite
sides of the slide or block and are adapted to reciprocate in suitable guide-
portions in the hub and in the pait es in said frame e, as clearly illustrated
in Figure 4. In order that the said block or slide may be normally forced up
against or in close proximity to the off-set e in said frame e, see Figure 4, said
block has a pair of oppositely extending screws or pins and , and on the

page_text: frame e are another set of screws or pins 2 and 3, said sciews or pins / and
having a connecting spring, and the sciews or pins and 3 a connecting
spring, which constantly act to draw the said block or slide in the direction
of the arrow in said Figure 4
The operation of the device is as follows.-
After a hat-body has been placed upon the block upon said vertical shaft n³
and the mechanism of the machine has been set in operation to cause the iotaly
motion of said shaft, its block and the hat-body thereon, the operator lifts the
pouncing attachment from the support g, and brings the moving belt in opera-
tive contact with all the parts of the hat-body The rotary motion of the rod f
in the bearing in said frame d, and the pivotal motion of said frame d on the
shaft co, as well as the rotary motion of said shaft and the frame or yoke in
which it revolves, allows the operator to twist the rod f to bring the device E
in the several positions upon the top or clown and the sides of the hat-body, as
will be clearly evident.
The said belt is provided with a granular surface of sand or emery, which
serves to diess and remove the han in the hat-body, in the manner of pouncing,
shearing or finishing hat-bodies, and owing to the yielding condition of the belt k,
when pressed against the surface of the hat-body, no damage can be done to the
hat-body by excessive heat or pressure
Owing to the sliding arrangement of the slide or block and the parts con-
nected therewith, the shape of the contact surface of the belt & will corespond
to that of the hat-body on the block, whereby a greater surface of the hat-body is
pounced, sheared or finished at one time, than 1 means of the constructions now
in use for these purposes, and with much better results in that a better finished
and a more even surface of the body is produced
The belt, which is usually but a piece of sand or emely paper on cloth, is of
a simple and cheap construction and is quickly and readily replaced by a new
belt when worn out with constant use
As an extra precaution, to prevent too great a pressure upon the belt due to
careless handling of the attachment E, I have pivoted upon a pin or screw mon
the frame e, as will be seen from Figures 2 and 3, a lever oi bai a piovided with
a slotted end n, which is arranged over a 1, no on said frame e by means of a
washer o and a nut on thumb-screw can be locked in its properly adjusted
position against the side of the frame e On a pin extending from one side
of said lever or bar n, at a suitable point between the pulley-wheels h and 7³
18 a roller on wheel of a flexible material, such as rubbci, which arts as a
cushion against the under surface of the moving helt k, when the latter 19 forced
to assume the curvature indicated in dotted outline in said Figure 3 Owing
to the arrangement of the slotted end of the bar and the thumb-screw 9,
said wheel 3 can be brought farther away or closer to the under surface of the
belt, as will be clearly understood
When it 18 desired to use the attachment for luring the hat-body, after it has
been pounced, the sand or emery belt can be removed and a felt or other suitable
belt can be arranged over the pulleys h³ and 3, said belt being previously sub-
Jected to a treatment of vaseline or other suitable substance of a greasy nature.
By my improvements herein set forth, a simple and efficient machine for the
purposes stated is the result, for operating upon a hat-body with less liability
to injury by the belt, than by the ordinary Bouncing roll or pouncing disc
covered with a surface of a granular nature, and the machine can be run more
economically and with better results in producing a more finely finished surface
of the hat-body
To prevent any curling of the edge of the belt k, with constant use, I have
secured upon the top of the frame e, by means of screws, or in any other suitable
manner, a plate p, which extends upwardly and slightly against the upper edge
of the belt k, nearest the side of the frame e, and is in slight contact with said
edge of the belt, substantially as represented in said Figures 2 and 3.
