Improvements in or relating to Blow-pipe Supports and the like.
We, GEORGE RUFFUS FORD, Machinist, and DAVID ALEXANDER, Machinist,
both of Michigan Trust Co. Building Grand Rapids, in the State of Michigan,
United States of America, 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 relates to a new and useful support for blow pipes, and analagous
purposes, and the invention relates to the coinbination with a blow-pipe, with
means for supplying gas, of a standard, and adjustable portion of the standard for
allowing a vertical adjustment, and a ball and socket adjustment furnishing means
for adjusting the blow-pipe with reference to the standard in any required direction
and the object of our invention is to obviate the necessity of moving and adjusting
the article to be operated upon, and to locate or mount a blow-pipe upon a standard
having sufficient adjustability to adjust the points of discharge of gas and air in
any required position upon the article operated upon.
This object we accomplish by means of the mechanism illustrated in the
accompanying drawing, in which,
Fig. 1 shows a side elevation of a standard with the blow-pipe mounted thereon
and containing our double adjustment, which is our preferred form.
Fig. 2 shows a vertical sectional view of the standard and a portion of the blow
pipe mounted thereon.
Fig. 3 shows a side elevation of a portion of the standard, and the adjustable joints
the same turned down so that the blow pipe is located at the side of the standard,
also illustrating the adjustable clamp.
Fig. 4. shows a vertical sectional view of the standard with the retaining bolt
raised in order to prevent the movement of adjustability of the lower half of the
ball and socket arrangement.
Fig. 5 is a sectional view on line 5-5 of Fig. 1.
Fig. 6 is a detail view of the clamp that holds the blow-pipe and allows the same
to be adjusted longitudinally.
:
Fig. 7. is a sectional view of a portion of the standard, with the support
containing a single ball and socket joint and also showing the clamp which attaches
the gas-pipe and blow-pipe to the movable portion which is secured within the
standard.
Similar letters refer to similar parts throughout the several views.
A represents the standard constructed of metal, or any suitable material.
B represents the blow-pipe, and C represents the pipe which conveys the jet of
gas; the connection between the blow pipe B and the gas pipe C being the
ordinary connection in blow-pipes.
E. represents a support which, in the example of our invention shown in Fig. 1,
is a socket, provided with a ball at its lower end, shown by G. L is the clamp
which engages adjustably with the gas pipe C so as to allow the gas pipe to be
moved longitudinally with reference to such connection.
M is a shank which fits into the socket E, and is adjusted vertically in said
socket E by means of a set screw H.

page_text: I-I are the clamping pieces which form the socket for the balls in making the
ball and socket joint. The screw J passes through the two parts I-I, and is
provided with a head or other means, as shown in Fig. 2, furnishing a convenient
means for clamping the sockets I-I upon the balls G, and the ball K, it
being understood that in this form of our invention we use a double ball and
socket joint, in which case the ball K may be formed on the upper end of the
standard A.
O is a rod or wire adapted to move longitudinally within the standard A there
being an opening extending upwards from the standard A. through the ball K and
into the ball G.
P, represents a pin or other suitable means for raising or lowering the rod Ó.
When it is desired to make the ball and socket joints rigid by means of the pin P,
the rod O is raised so as to pass through both balls G and K, when the standard
will be rigid, and the only adjustment which can be then made is a vertical
adjustment by means of the shank M and the adjusting nut H.
In Figs. 1 and 2, the rod O is lowered to the lowest point, so that both of the
ball and socket joints may be used and in Fig. 4 the pin P is raised, thereby raising
the rod O so that only the upper ball and socket joint can be used.
F is a valve whereby the flow of gas through the pipe C may be regulated or
shut off entirely through the will of the user.
.T represents a pin having a head to bear against one of the clamping pieces I,
and extending through it so as to receive the nut J, and by turning the nut J the
clamping pieces II are either drawn towards each other or moved from each other.
This pin T has a hole which allows the rod O to pass through it when moved
upwards into the ball G.
In many cases it will not be necessary to have the double ball and socket joint,
but a single ball and socket joint as shown in Fig. 7 will answer all practical
purposes as it will allow for a vertical adjustment and lateral adjustment of the
blow-pipe, and also allow the blow-pipe to be turned nearly a revolution; but
where it is necessary to direct the jet of gas upon the underside of an article to be
operated upon, we deem the double adjustment preferable. The double adjustment
also allows the operator to obtain a greater vertical adjustment than can be obtained
by a single ball and socket joint.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In combination with a blow-pipe, a standard and a ball and socket joint
whereby the said blow-pipe can be adjusted to any required angle with reference
to the standard, substantially as described.
2. In combination with a blow-pipe, a pipe for conveying gas, a clamp allowing
a longitudinal adjustment of the blow-pipe, a socket and a shank fitting into the
socket allowing a vertical adjustinent of the blow-pipe, and a ball and socket joint
allowing the blow-pipe and shank to be adjusted at any required angle, substantially
as described.
3. In combination with a blow-pipe, a ball and socket joint, a standard, and a
vertically moving rod and suitable means for operating said rod for converting
said standard from an adjustable one into a rigid standard, substantially as
described.
4. In combination with a blow-pipe and gas-pipe, a clamp for securing the said
blow-pipe and allowing of longitudinal adjustment with reference to the clamp, a
sbank fitting into a socket, and suitable means for adjusting said shank vertically
therein, a ball and socket joint allowing adjustment at any required angle, a clamp
for operating the said ball and socket joint, a standard. and a second. ball and
socket joint at the top of the standard allowing the double adjustment by means of
all the ball and socket joints, substantially as described.

page_text: 5. The combination of a blow-pipe, and the pipe furnishing the gas jet, a double
ball and socket joint, a standard, and a vertically moving rod within the standard
adapted to be moved from the standard into and through both of the ball and
socket joints, substantially as and for the purpose described.
Dated this 14th day of August 1895.
