ALBERT F. HECKEL, OF GALVESTON, TEXAS.
CUTTER-HEAD,No. 834,299.
To all whom it may concern:
Be it known that I, ALBERT F. HECKEL, a
citizen of the United States, residing at Gal-
veston, in the county of Galveston and. State
5 of Texas, have invented a new and useful
Circular Saw, of which the following is a
specification.
This invention relates to cutter-heads for
shaping and dressing jambs; and its object is
io to provide a .compact and durable device of
this character which is adjustable, so as to
produce door-jambs, pulley-jambs, and vari-
ous other articles requiring the use of rotata-
ble plow-bits, rabbeting-knives, &c.
15 A still further object is to combine one or
more saws with the cutter-head, so that the
completed articles may be cut from the stock
during the dressing and shaping operation.
Another object is to provide a saw which is
20 so constructed as to permit the knives on the
cutter-head to extend thereinto, and thereby
insure the dressing of the stock up to the saw
cut.
With the above and other objects in view
25 the invention consists of a rotatable head
mounted on a mandrel in any well-known
manner, and secured to the mandrel at one
end of the head are one or more circular saws
having oppositely - disposed parallel slots
30 therein,. the slots of all of the saws alining.
Dressing-knives are adapted to be secured
upon opposite faces of the head, and one end
of each knife projects into one set of slots in
the saws, so as to insure the dressing of the
35 stock up to or Past the saw cut. Knives
having cutting edges of any suitable contour
for producing' grooves, rabbets, &c., are
adapted to be fastened to the other faces of
the cutter-head.
40 The invention also consists of certain other
novel features of construction and combina-
tions of parts, which will be hereinafter more
fully described, and pointed out in the
claims.
45 In the accompanying drawings is shown
the preferred form of the invention.
In said drawings, Figure 1 is a front eleva-
tion of a cutter-head arranged to produce a
dressed pulley-jamb and two parting strips
50 from rough stock at one operation. Fig. 2 is
an end view of the device, and Fig. 3 is a sec-
tion on line x x, Fig. 1.
Referring to the figures by characters of
reference, 1 is a mandrel of the usual form and
55 on which is disposed a head 2, having secur-Patented Oct. 30, 1906.
ing-bolts 3, adjustably mounted in slots 4,
formed in opposite faces of the head. The
mandrel extends beyond the head and is
adapted to clamp one or more circular saws
5 in position thereagainst. Where a plurality 6o
of saws are employed, the same are spaced
apart at desired distances by means of wash-
ers 6, and a tap 7 is utilized for clamping a
ring 8 against the saws, so as to hold them
tightly in position upon the mandrel. Each 65
of these saws has two oppositely-disposed
parallel slots 9 therein, and when aplurality
of saws are employed, as shown in Fig. 1, the
slots thereof are placed in alinement. Dress-
ing-knives 10 are adapted to be secured upon 70
opposite faces of the head, and each is adapt-
ed to be held in place by means of bolts 3,
which extend through slots 11, formed with-
in said knife in the usual manner. One end
of the knife is extended through one set of 75
lining slots 9, so that the extremities of said
knife will lie flush with the outer face of the
outer saw 5. The bolts 3, extending from
the other faces of the head, are placed in en-
gagement with cutting-tools, the working 8o
edges of which are of any desired contour.
Where it is desired to produce a pulley-jamb,
an edging-tool 12 is secured to the head, so as
to form one edge of the jamb, and a plow-bit
13 is clamped upon the head at a desired dis- 85
tance from the edging-tool for the purpose of
producing a groove. Where the cutter-head
is arranged to produce a pulley-jamb and
spacing-strips, the saws 5 are spaced apart a
distance equal to the width of the groove 90
produced by the plow-bit 13.
When the parts have been assembled in
the manner described, the head is rotated by
means of any suitable mechanism, and rough-
dressed stock is fed thereto. The saws 5 will 95
rip the stock, so as to produce two spacing-
strips 14, and the dressing-knife 10 will pro-
duce a finished outer surface thereon and
upon the jamb 15. At the same time the
edging-tool 12 will dress one edge of the jamb, ioo
while the plow-bit 13 will cut the groove 16,
said groove being of the same width as either
of the strips 14. It is of course understood
that all but one of the saws may be dispensed
with, if desired, and in such case two-width, [05
stock may be fed to the cutter-head, so that
at the first cutting operation a finished jamb
will be cut from the stock, after which the re-
maining rough portion of said stock can be
fed to tie head and a second jamb produced. 1oSpecification of Letters Patent.
