IMPROVE- MENTS IN MACHINERY FOR SCOURING AND POLISHING BRASS AND OTHER METAL TUBES AND RODS
Year: 1884

page_text: I THOMAS KENDRICK of Summer Lane Birmingham in the County of Warwick
Manufacturer do hereby declare the nature of my said Invention for "IMPROVE-
MENTS IN MACHINERY FOR SCOURING AND POLISHING BRASS AND OTHER METAL
TUBES AND RODS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the Drawings hereunto annexed and to the letters and figures
marked thereon that is to say :-
This Invention consists of a peculiar arrangement and combination of mechanical
appliances by which an automatic reciprocating action is imparted to a band
charged with rotten stone or other suitable polishing medium and which band is
wound over the tube or rod under operation.
The machine is intended to apply more especially to the polishing of brass tubes
for bedsteads pillars and its object is to supersede the slow and laborious exercise
of manual labour to produce superior finish and regularity of surface and to attain
these results more economically and with greater speed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of the machine seen from above.
Figure 2 a side elevation of the same.
Figure 3 an end elevation between the two tables and slide beds.
I will now proceed to describe the Invention by the aid of these Drawings.
The machine is erected upon stands or legs A surmounted by a planed bed B.
and is put in motion by means of a disc-plate C acted upon by a band D. From
the disc plate C. the motion is transmitted to the rest of the machine through the
medium of levers E keyed on to the shaft F which takes its bearing in plummer
blocks at points G. Figure 2.
By means of this arrangement an oscillating movement is imparted to the radial
arms H which are also keyed on to shaft F and are fitted with powerful toothed
spring clips I (regulated by a cam and key) to receive the strips of list or other
substance which may be employed for the purpose of polishing the tube or rod.

page_text: The machine is provided with a reversible automatic action whereby the tube is
made to travel horizontally throughout its entire length during the process of
polishing without break or intermission.
This is accomplished by means of a shaft J. to which the disc plate C. is attached
and which shaft J. rests in plummer blocks K which are supported by projecting
brackets. To the end of this shaft J is attached a pulley L which acts by means
of a band M and pulley N upon a worm-spindle O. putting in motion the worm
wheel P. Figure 2. The worm wheel P acting directly upon a grooved chain
wheel Q, puts in motion the endless chain R. which traverses the entire length of
the bed returning over a second chain wheel S.
The object of this chain arrangement is to actuate the saddle plate T. which
slides along the bed B. to which chain it may be attached at will by a fork or
clip U which passes through the saddle plate T into the links of the chain R. and
is raised or lowered by the lever or handle V.
Upon the saddle plate T is constructed an appliance working in conjunction with
a second saddle plate arrangement W and consisting of chucks or jaws X with set
screws to receive the ends of the tube or rod to be polished.
This appliance is made adjustable by the wheel Y and the ratchet and spring Z.
the object of this being to enable the operator to overcome the difficulty presented
by any obstacle or projection upon the tube or rod (as for example the corner block
as shewn in Figure 2) by suspending the horizontal motion of the saddle plate T
and imparting a rotating motion to the tube thus allowing the list or other
polishing band to act upon the whole of its surface.
In operating upon tubes which may be too long or too weak to support the
strain of the polishing band I can insert a mandril to give sufficient strength
during the process.
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 :-
The peculiar combination of mechanical appliances which I have described
forming a machine adapted to work with an automatic oscillating action in
imitation of manual operation, a band of list or other suitable material for the
purpose of scouring or polishing brass and other metal tubes or rods.
