Chapter XIII: Part 13

Figs. 420 and 421, are full-size drawings of my eccentric chuck on my upper mandrel, used for producing the foregoing specimens. In this case I have preferred a wood foundation, as not being so likely to run off as metal, on reversing the motion which is sometimes necessary on account of idle wheels for the connections. I used a piece of well-seasoned Spanish mahogany, taking care that the grain of the wood was at right angles with the length of the screw of the mandrel. A piece of brass is screwed at the back to prevent the screw cutting into the wood. Fig. 420 is a section, and Fig. 421 a front view of the chuck, and I think all sufficiently clear. I will just say the long fine threaded screw I cut up with the stocks and dies in the lathe, using steel wire of the necessary size. This I manage easily, and keep the wire straight _by allowing it to expand in length_. I chuck the steel wire concentrically, and removing the centre from the back poppet, substitute a brass centre with a hole the size of the steel wire, which is allowed about a quarter of an inch entry. I then turn down a little below the depth of the intended screw thread for about half an inch in length next the back centre, to allow the dies to come back to be tightened up, and which must only be done at the commencement and not on the return motion of the dies. The collar on the screw is a piece of brass with a hole of a size to drive on the wire tight, and is then pinned on and turned up true, and finished with the division marks.

OVAL TURNING AND ROSE CUTTING WITH TEMPLATES WITH MY
APPARATUS.

Figs. 422 and 423 are full size drawings of my chuck, with circular movement for templates for my upper mandrel, which has also a wood foundation. Fig. 422 is a section, and Fig. 423 is a front view.

By removing the eccentric chuck from the upper mandrel, and substituting the chuck Figs. 422 and 423 with a circular movement, to receive templates of any pattern, OVALS with the oval template can be turned and also with any irregular templates, patterns cut and placed in any direction over each other, by causing the templates to work against a rubber or roller as most desirable, with an india-rubber spring to keep them together.

The following illustrations will give some faint idea of productions from templates.

Fig. 424, is the production of an oval template and slide-rest movement, both mandrels making equal revolutions.

Fig. 425 the same as Fig. 424, with the patterns laid across each other by turning the circular movement of the chuck 12 divisions.

Fig. 426, is from an oval template, which is caused to make two revolutions to one of the lathe mandrel producing 4 waves and undulations and with the slide-rest movement. It will be perceived in this case the form of the _oval_ is superseded by another pattern, and shows how great a change in the form of patterns from templates my rose engine with change wheels effects.

Fig. 427, is also from an oval template, caused to make 5 revolutions to one of the lathe, and with the circular movement of the chuck and the slide-rest movement, and in this case the form of the oval is also superseded. Indeed, none but those who have made the matter their study would have the slightest idea that this pattern could be produced from an oval template.

Fig. 428, is also from an oval template, it is finer than 427, but is done in the same way by the template making _nine_ revolutions to one of the lathe mandrel.

The above are a few specimens of the oval, but sufficient to draw attention to the great variety of patterns that can be executed, and these illustrations have only been made to go even revolutions with the lathe mandrel; but of course can be made to go, as already described, uneven revolutions, laying the lines over each other for variety of patterns.

Fig. 429, is a curiosity from a square template with equal revolutions, the outside rim and inside pattern by the circular movement of the template chuck.

Fig. 430, is also from a square template made to go two revolutions to one of the lathe and with the slide-rest movement. The centre pattern with the circular movement of the chuck.

Fig. 431, is the production of a heart-shape template, and with the slide-rest movement and the patterns laid across each other, the mandrels making equal revolutions.

Fig. 432, is also from a heart-shape template made to go two revolutions to one of the lathe and the slide-rest movement. But in this case the slide-rest tool is used _on the opposite side of the lathe bed_ to the roller against the template, and therefore reversing the pattern, that is, the projections of the pattern are the hollows of the template, and _vice versa_. I have introduced it to show how easily patterns are multiplied in the most simple way. It will also be observed that the form of the template is superseded.

Fig. 433, is another illustration of the heart-shape template, but made to go five revolutions to one of the lathe, with the circular movement of the template chuck, and the slide-rest movement, and in which case the form of the template is entirely superseded.

Fig. 434, is also a similar illustration to 433, only finer; they can be of course as fine as desired.

The above are, I think, sufficient to illustrate the productions from templates, some very pretty patterns can be executed. My object is more particularly to exhibit the use and extended application of my rose engine, and it will be perceived the last two are not the most easily working templates.

The variety of patterns that can be executed with this engine are so innumerable that one may say they are infinite. Well may you in your article quote what Bergeron says of the rose engine, "that it is necessary to know thoroughly the particular one in use."

I also make use of the cogwheel on my mandrel, by connecting it by a spindle and the change wheels with a large compound slide rest, for executing spiral turning, and also with my slide rest for ornamental turning, for small spiral work; and with a chuck with a circular movement I can cut several spirals to one stem.

In concluding my description I will say the specimens given have all been cut on a plain surface, and this has been unavoidable on account of printing, but for the information of those unacquainted with the rose engine, the very great advantages of which over the eccentric and geometrical chucks are that the work can be executed on concave or convex surfaces. I make use of mine for ornamenting the roofs of temples and Chinese pagodas, either domed, curvilinear, or circular pointed, by representing them covered with shingles, &c. The geometric chuck will produce very beautiful intricate lacework, but not more so than my apparatus, as they both are on the same principle of change wheels, and can both produce equally fine work; but with my apparatus the work is always concentric with the mandrel, and therefore much more pleasing to execute.

(From the _Weekly Times_.)

"Technical education forms just now a topic of more than
ordinary importance, and, as far as we can see, 'The English
Mechanic' fills a large space in providing technical food for
the workmen of Great Britain. There is scarcely a subject in
the scientific or mechanical world that is not practically
described in this excellent journal, and all the technicalities
explained with a particularity quite remarkable. Here the
workman in all departments of trade will find something to
interest him, and many things explained by which he will be
able to make the best use of his knowledge. The editor is
always anxious to satisfy the cravings of his readers by giving
every information possible to those who may require it. The
trouble taken in this department is apparent on reference to
the 'Letters to the Editor' and 'Replies to Queries,' both
of which form original, very important, and useful features
of the magazine. Under the head, also, of 'Our Subscribers'
Exchange Club,' a means is opened for persons to exchange one
article for another on mutually advantageous terms, and for this
accommodation no charge is made. For instance, one correspondent
says he has a silver watch which he would exchange for 'The
Lives of Eminent Men;' another wants 'a cottage piano' for 'a
three-horse power horizontal engine;' and a third has 'a hand
sewing machine,' which he would give for 'a parallel sliding
vice.' The illustrations of 'The English Mechanic' are worthy
of all praise; they are drawn with an exactness which is so
necessary, and so much appreciated by workmen, and are also well
printed. Throughout the whole publication there is a visible,
a practical, and technical knowledge of a high order--a kind
of knowledge that is highly prized by all mechanics and men of
science."

W. J. CUNNINGHAM AND CO.

Beg to call the attention of the Public to their newly-invented Ornamental Wood and Metal Cutting Machine. Its extreme simplicity of construction precluding the possibility of speedily getting out of order, having no springs, and its peculiar adaptability to all kinds of fret-work render it at once an acquisition and an indispensability where accuracy, expedition, and high finish are required. The working is exceedingly easy, requiring no more exertion than an ordinary Sewing Machine for ladies' use, and making as little noise. Its great utility, combined with neatness of construction, fits it not only for the workshop, but the drawing-room of the amateur. The saw takes the place of a pencil in the hands of the operator, enabling him to produce the most elaborate artistic designs in wood-work. Box or other hard texture woods, 1 inch thick, are as readily sawn through as the finest veneer; metallic plates of 1/8 inch thick are also speedily pierced. Magnificent specimens executed by this machine, which have been universally admired for their extreme delicacy and perfection, and acknowledged to be unrivalled, may be seen at the inventor's address. The length of stroke of the saw can be varied to the work in hand. A simple mechanical contrivance is attached for blowing the sawdust from the saw whilst working, also a Circular Saw.

An equally valuable invention is W. J. C. & Co.'s PATENTED DRILLING APPARATUS which is with the greatest advantage combined with the Sawing Machine, enhancing and enlarging its range of usefulness, or it may be adapted to a lathe, or as a distinct machine. Its great advantages over the ordinary lathe for drilling purposes must be apparent when by the addition of this apparatus to a 5 inch centre lathe the operator is enabled to drill in the centre of three or more feet, and the drill being vertical and worked by leverage, greater accuracy and facility is ensured. For ornamental purposes it surpasses all hitherto contrived methods, not being limited to one centre around which to describe curves, angles, circles, or any other mathematical figure, the operator is at perfect liberty to describe every conceivable device the fancy can dictate.

Advantages and Capabilities of this Machine.

Transcriber's Note:

1. Page 38, Bunhill-row, Covent-garden and Charing-cross seems to be
an old-fashioned way of writing.

2. Italics are shown as _text_, bold is shown as =text=.

3. Carat characters are shown as ^X.

4. This table of contents has been created by the transcriber to aid
the reader.

5. Footnote 20, Page 183: Footnote marker is missing.

6. Page 238: starting the 3rd table, there is a fraction 33-1/14. This
has been changed this to 33-1/16, as it seems to be a mistake.

7. Spelling errors such as guidepiece, sawgates, swiveljoint, tongueing
and whiteing have been retained as they are in the original.

8. Discrepancies with 3/4-inch and 1/4in. have been retained as in the
original.

9. Inconsistencies with images:

a. Page 22: Fig 31D is incorrect in the book as E. Changed to 31D and
the fig. no. on the image has been removed.

b. Pages 36 & 38: numbers 53-56 are repeated.

c. Page 74: It seems the reference (Fig. 126) should be Fig.116.

d. Page 89: There is no Fig. 137 or a reference to it.

e. Page 99: The number 9 on the image is back to front. There does not
seem to be a Fig. 148, although it is referred to (page 98).

f. Page 98: Fig. 148 is incorrectly numbered on the image as 143.

g. Page 100: There is a 2nd reference to Fig. 149, which it seems has to
be an illustration of a pattern, but there is no 2nd Fig. 149. It
seems the Fig. nos. mentioned in the reference should be 150 to 153.

h. Page 104: The illustration is incorrectly numbered as 153 (should be
156).

i. Page 107: The number 9 on the image is back to front.

j. Page 111: The number 6 on the images is back to front.

k. Page 112: Fig. 166 incorrectly numbered as 165.

l. Page 141: There is no Fig. 204. (assumed to be the top image above
Fig.205).

m. Page 159/160: Number repeat for Fig. 229.

n. Page 160: There is no Fig. 230. Possibly the 2nd no. 229.

o. Page 178-184: Numbers 246-255 are number repeats.

p. Page 185/6: There is no Fig. 257, but no reference to it either, so
it is assumed this was an omission by the author.

q. Page 189: There is no Fig. 261, although it is referred to on page
189. The reference has been changed to Fig. 262, which it pertains
to.

r. Page 201: Fig. 284 is out of sequence, it appears on page 209.

s. Page 207: It seems the reference should be to Fig. 290, not 296 which
has no L in the figure.

t. Page 231: Fig, 319 is referred to, but there is no Fig. 319.
Presumably the first figure on Page 233.

u. Page 236: Illustration top un-numbered, presumably 4.

v. Page 278: Figs, 422/3 is referred to, but there are no Figs. 422/3.
Based on extensive research, comparing two different copies of a
matching edition, and correlation of illustrations with the text,
it appears that the inconsistencies in numbering within the book make
it seem that something is missing. The images are in fact Figs. 420
and 421.
