Improvements in Machinery for Making Felt Hats.
I, BENNO BARUCH, of the Firm of F. Bambus & Co., 67, Chaussee Strasse,
Berlin, in the German Empire, Hat 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 :-
My invention relates to an improved machine for preparing the sheet of wool
for the felting cone in the process of making felt hats.
In the machines at present in use, a quantity of material is unnecessarily
worked into the felt cone, which material must be again removed during the
subsequent operations.
By my invention I provide means for removing at the commencement of the
operation, and before the felting has commenced, of most of the wool which
would afterwards have to be removed in the felted state from the partly finished
hat, being the portion finally trimmed off the edges of the brim after
felting.
I effect this by means of a little cutting comb which comes into operation as
soon as the forming of the sheet of wool into shape for the hat body and the brim
begins to take place, which comb is operated by means of the devices illustrated
in the accompanying drawings in which:
Figure 1 shews a perspective view of that end of the machine upon which the
cone apparatus is placed.
Figure 2 is a section on the line x-x of Fig. 1.
Figure 3 is a section on the line y-y of Fig. 1.
Figure 4 is a perspective view of the cutting comb.
Figure 5 is a detail for the release of the actuating mechanism for the cutting
comb.
The shaft which bears the cutting comb a is revoluble in a special bearing c
placed at the hinder part of the frame of the machine. The said shaft b receives
a rocking motion by means of the crank d and the crank rod e from the pulley f.
This pulley is actuated by means of the belt g as soon as the fork h is moved so as
to transfer the said strap from the loose pulley f¹ to the fixed pulley f. The
movement of the said fork h is effected by means of the bar k controlled by the
spring. The bar k is provided for this purpose with an adjusting arm m, which
arın is adjustable by means of a sleeve n placed upon the bar k. . The said bar
also possesses a brake cone o which is also adjustable by means of a screw. Upon
the said cone o there rests a doubly bent angle lever q pivoted to the machine
frame at p, which lever stands under the influence of the spring r². The arm m
and the brake lever q for the cone o are under the control of the arms 8 and t
attached to the shaft 6. The shaft 6 connects to a controlling apparatus of known
construction, (which forms no part of my present invention), illustrated in the
drawing diagrammatically in Figure 3.
The machine is operated as follows:-
When the hat brim is to be formed, the operator depresses the treadle z (Figure 3).
This causes the arm y to rise, and revolves the shaft attached to it which in turn
causes the arm w to move aside and consequently the counterweight supported

thereby falls down. The counterweight v is fixed on the shaft 6, and consequently
revolves this until the first tooth of the partially toothed worm wheel 5 strikes
against the worm on the continuously revolving shaft 2 which is the main driving
shaft of this portion of the apparatus. The shaft 6 is now caused to revolve until
the bars fixed thereon strikes against the pin m of the horizontal bar k kept
normally in its place by the aid of the spring 1. The bar k is now moved inwards
against the spring, causing the belt h to shift the belt g from the loose pulley f¹ to
the fast pulley f. The eccentrically attached bar e is thereby set in reciprocating
motion conveying through d and b a to-and-fro motion to the cutting comb a.
The bark is held in position for a short time by the angle arm of the brake
lever q which slides up over the cone o and drops down behind its base under the
pressure of the spring ; on the shaft 6 continuing to turn, the arm t' depresses the
other end of the brake lever q, against the pressure of the spring r, until the bent
arm of q liberates the cone o and allows k to spring back, shifting the belt from the
fast to the loose pulley accordingly and throwing the cutting comb out of use. The
operation can then be repeated by depressing the treadle z.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Adjustable mechanism for the cutting comb in felt hat machines characterised
by the arrangement that upon the actuating of the cutting apparatus by means of
the worm wheel 5 thereof, (which apparatus is held in check during the period in
which no rim is to be formed by means of the weight v and the supporting arm w,
whereby the bar k is moved by an arm such as 8 and the fixed belt pulley f is put
in gear by means of a fork / connected to the said bark whilst during the latter
part of the revolution of the shaft 6 the said bark which has been hitherto
held by means of the cone c and the angle lever q is again released, the counter
weight is again replaced upon the supporting arm wand the fork h is shifted
with the belt and throws the pulley out of operation substantially as described.
2. In the mechanism set forth in Claim 1 the arrangement of the cutting comb a
upon the shaft b, which latter is set in quick motion by means of the crank d and
rod e, by means of the belt pulley f, substantially as described.
3. The improvement in mechanism for the manufacture of felt hats, substantially
as set forth and illustrated in the accompanying drawings.
