GEORGE R. CLARKE, OF MONTELL, TEXAS, ASSIGNOR TO HENRY H. TURNER
AND ALBERT TURNER, OF DANBURY, CONNECTICUT.
POUNCING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 602,978, dated April 26, 1898.
Application filed December 17, 1896. Renewed October 1, 1897. Serial No. 653,746. (No model,o all whom it may concern;
Be it known that I, GEORGE R. CLARKE, a
citizen of the United States, residing at Mon-
tell,Uvalde county, Texas, have invented cer-
5 taro new and useful Improvements in Pounc-
ing-Machines,of which the following is a speci-
fication.
This invention relates generally to a ma-
chine for pouncing the crowns' of hats, and
10 specifically to certain improvements on the
machine embodied in my application, Serial
No. 577,650, filed February 1, 1S96, and now
pending.
The features of improvement will be here-
15 inafter described and carefully distinguished
from the old features of the machine as shown
in the said pending application.
In the accompanying drawings an embodi-
ment of the improved machine is illustrated.
20 Figure 1 is a side elevation of the machine
as it appears at the termination of the pounc-
ing operation, the base of the pedestal being
in section. As the operator stands at the
right in Fig. 1 and facing the machine this
25 view shows the left-hand side thereof. Fig.
2 is a front elevation of the upper part of the
machine, on a larger scale than Fig. 1, show-
ing the parts in the position they occupy at
the beginning of the pouncing operation; and
30 Fig. 3 is a side elevation as seen from the right
in Fig. 2. These views, Figs. 2 and 3, include
the novel features of this invention. Fig. 4
is a face view of the pouncing-pad detached.
I will first briefly explain the general con-
35 struction and operation of the machine, as
more fully set forth in the above-mentioned
pending application, and then describe the
novel features.
On a hollow pedestal or frame 1 is mounted
4o a head 2, which is carried by an upright hol-
low shaft 3 in the pedestal, and during the
pouncing operation said head is turned slowly
around through about a quarter-revolution.
When the operation is completed, the driving
45 mechanism is automatically thrown out of
gear, (as here shown by shifting a belt,) and
the head may be then unlocked or discon-
nected from its shaft and turned back again
to the starting-point. The hat II to be pounced
5o is fitted on a block clutched to a horizontally-mounted shaft in the head, and this shaft is
driven, through intermediate mechanism,
from an upright shaft 4, extending through
the hollow shaft 3. The hat is thus rotated
slowly about its axis at the same time that it 55
is carried about with the head 2. The main
driving-shaft 5 in the base of the frame or
pedestal drives the shafts 3 and 4 through
any suitable gearing. In Fig this consists
of a peculiar differential gear, which is fully 6o
described in the said pending application. As
the hat H is rotated it is pounced by a pounc-
ing-pad 6, carried by an arm 7 and held up to
the hat by a spring in a casing S on the ped-
estal or frame. The pad 6 receives motion 65
in a closed curved path through the medium
of a counter-shaft 9 in the frame, driven from
the main shaft 5. On the end of the shaft 0
is a crank 9V, to which the lower end of the
arm 7 is coupled, and the said arm has a slid- 70
ing bearing at 10 in a frame 11, hinged to the
pedestal 1. All of this is clearly illustrated
and described in the said pending application.
I will now describe with more particularity
the means employed for giving to the hat 75
what is called an " oval" motion about its
axis, premising that as a hat-crown is ellip-
tic or oval in cross-section and the pad is
held up to it by a yielding spring-pressure it
is desirable that the center of rotation of the 8o
hat shall be moved to and fro during the ro-
tation toward and from the pouncing-pad in
order to compensate for the elliptical form
of the hat - crown, and thus avoid variable
pressure of the pad on the hat during its ro- 85
tation.
On the upper end of the shaft 4 is fixed a
bevel-wheel 12, which gears with a bevel-pin-
ion 12', fixed on a counter-shaft 13, mounted
in bearings in the head 2 perpendicular to 90
the shaft 4. On the shaft 13 is fixed a gear-
wheel 14, which gears with a similar wheel
14X, of twice; its size, fixed on the shaft 15,
which carries the hat 11 and which is rota-
tively mounted in a bearing-piece 16, mount- 95
ed loosely on the shaft 1.3, at its foot, and
adapted to swing or oscillate about the axis
of said shaft 13 as a center. The shaft 15 is
substantially parallel with the shaft 13, and
the oscillation of the bearing-piece 16 does xoo
