HUNLEY BIBLE, OF SHERMAN, rTEXIA S.
WOOD-COLUMN-TURNING LATHE.No. 865,673.
To all whom it may concern:
Be it known that I, H-uNLEY BIBLE, a citizen of the
United States, residing at.Sherman, in the county of
Grayson and State of Texas, have invented certain
5 new and useful Improvements in Wood-Column-
Turning Lathes, of which the following is a specifica-
tion.
This invention relates to improvements in means
for turning and fluting colonial wood columns. and
10 has for its object, among others, the production of a
simple and effective device which may be used for
moving the carriage lengthwise of the lathe bed, and
for operating the cross-feed of same.
It has for a further object to provide the cross-slide
15 of carriage with a cutter head that may be swiveled
and locked in any desired position, thus bringing the
cutters for the different service required in operative
position to perform same.
It has for an object, further, to so dispose the rollers
2> upon which the carriage runs and the operating mech-
anism where they will be out of the way of the dust
and chips.
Still a further object is to decrease the frictional
contact, whereby the carriage can be made to run
25 easier.
Other objects and advantages of the invention will
hereinafter appear, and the novel features thereof will
be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accom-
30 panying drawings, which, with the letters of reference
marked thereon, form a part of this specification, and
in which-
Figure 1 is a side view in section, taken longitudi-
nally through the carriage base, showing the lathe car-
35 riage mounted in operative position upon a cross-sec-
tion of the lathe-bed, and illustrating the relative
construction and arrangement thereof. Fig. 2 is a
plan view of the same; Fig. 3 is a rear end view of the
carriage, and fragmentary side view of the lathe bed;
40 and Fig. 4 is a view showing the finished end of a col-
umn. Fig. 5 is a front elevation of the swinging head
with the ends of the spindle shown in section.
Referring now to the details of the drawings by let-
ter, A designates the wooden bed or shears of a lathe,
455 .to one end of which is secured in the usual manner an
ordinary lathe-head, and at the opposite end an ordi-
nary tail-stock, as commonly used on wood turning
lathes; neither of which is shown in the drawing.
Secured to outside of lathe shear, and extending
50 along front side of lathe, is provided a wooden track
B, capped with a thin plate of iron B' and spaced a
slight distance from the shear A by blocks B2. To
the outside of back lathe-shear, and extending the
length of same is provided a V shaped metal track C
55 carried by metal brackes C' and additionally sup-Patented Sept. 10, 1907.
ported by metal bar C2; on these tracks, B, and C, run
rollers which carry the lathe-carriage.
D is the base of the carriage made practically T
shaped by providing the rear end with lateral exten-
sions D', beneath which are overhanging aprons D2, 60
in which are mounted horizontal shafts E, carrying
guide roller F, having V shaped peripheries adapted
to run on the V track 0, and thus carry the rear pr-
lion of carriage. Extending the length of metal bar
C2 and secured thereto is an L or angle iron C3. The 65
downwardly projecting hooks C0 secured to outer
apron D2 pass along under projecting flange of the
angle bar thus holding the back portion of car-
riage to track C. Secured near front end of carriage-
base D, on the under side thereof, and preferably 70
made integral therewith, is a downwardly projecting
lug D3, provided with an outwardly projecting pin G
on which is loosely journaled a roller H adapted to
run on the track B and by which the front end of car-
riage D is carried. 75
Motion is transmitted to the carriage from a suitable
lead-screw, sprocket chain, or other equivalent device,
which may be driven in the usual manner by a driv-
ing-shaft or other prime motor, and when the feeding
device consists of a lead-screw I, as illustrated, it 80
passes through a downwardly projecting lug I' at-
tached to carriage-base D; the lug being bored and
threaded longitudinally to receive the screw. In
place of the solid nut as shown, one provided with
means for opening and closing it can be employed, 85
which would enable the carriage to be quickly drawn
back by hand.
The cross-slide DT is fitted in suitable guiding ways
D" upon the top of the carriage base D, and carries a
swinging or oscillating head J, around the base of 90
which is provided a circular recess J' that fits a circu-
lar raised portion J2 formed on the top side of cross-
slide D=, being movably held in this position by stud
bolt J3. At the side of swinging head J is a projecting
lug J to which is bolted a lever J by which the head 95
may be turned to any desired angle and then securely
locked. by the stop screw J. As shown, the cross-slide
D4 is operated by means of a screw K running trans-
versely of the carriage; said screw being journaled at
K' appurtenant to or integral with carriage base D, 100
moving the cross-slide D4 through the medium of nut
K"2 integral with said cross-slide. The cross-feed screw
K is provided at its forward extremity with the crank
K3 secured thereto, which may be operated, whenever
desirable to move the cross-feed. 105
The swinging head J carries two vertical standards
L, that terminate in journal boxes L', carrying the cut-
ter head spindle Lr that is provided with a pulley L
and preferably driven by an over head drum, not
shown. Secured to one end of the spindle L2 is a cut- 110Specification of Letters Patent.
