The present Messrs。 Fox of Derby; who continue to carry on the

business of the firm; claim for their grandfather; its founder; that

he made the first planing machine in 1814;*

 'footnote。。。

Engineer; Oct。 10th; 1862。

 。。。'

and they add that the original article continued in use until quite

recently。  We have been furnished by Samuel Hall; formerly a workman

at the Messrs。 Fox's; with the following description of the

machine:   〃 It was essentially the same in principle as the planing

machine now in general use; although differing in detail。  It had a

self…acting ratchet motion for moving the slides of a compound slide

rest; and a self…acting reversing tackle; consisting of three bevel

wheels; one a stud; one loose on the driving shaft; and another on a

socket; with a pinion on the opposite end of the driving shaft

running on the socket。  The other end was the place for the driving

pulley。  A clutch box was placed between the two opposite wheels;

which was made to slide on a feather; so that by means of another

shaft containing levers and a tumbling ball; the box on reversing was

carried from one bevel wheel to the opposite one。〃  The same James Fox

is also said at a very early period to have invented a screw…cutting

machine; an engine for accurately dividing and cutting the teeth of

wheels; and a self…acting lathe。  But the evidence as to the dates at

which these several inventions are said to have been made is so

conflicting that it is impossible to decide with whom the merit of

making them really rests。  The same idea is found floating at the same

time in many minds; the like necessity pressing upon all; and the

process of invention takes place in like manner:  hence the

contemporaneousness of so many inventions; and the disputes that

arise respecting them; as described in a previous chapter。



There are still other claimants for the merit of having invented the

planing machine; among whom may be mentioned more particularly

Matthew Murray of Leeds; and Richard Roberts of Manchester。  We are

informed by Mr。 March; the present mayor of Leeds; head of the

celebrated tool…manufacturing firm of that town; that when he first

went to work at Matthew Murray's; in 1814; a planing machine of his

invention was used to plane the circular part or back of the D valve;

which he had by that time introduced in the steam…engine。  Mr。 March

says; 〃I recollect it very distinctly; and even the sort of framing

on which it stood。  The machine was not patented; and like many

inventions in those days; it was kept as much a secret as possible;

being locked up in a small room by itself; to which the ordinary

workmen could not obtain access。  The year in which I remember it

being in use was; so far as I am aware; long before any

planing…machine of a similar kind had been invented。〃



Matthew Murray was born at Stockton…on…Tees in the year 1763。  His

parents were of the working class; and Matthew; like the other

members of the family; was brought up with the ordinary career of

labour before him。  When of due age his father apprenticed him to the

trade of a blacksmith; in which he very soon acquired considerable

expertness。  He married before his term had expired; after which;

trade being slack at Stockton; he found it necessary to look for work

elsewhere。  Leaving his wife behind him; he set out for Leeds with his

bundle on his back; and after a long journey on foot; he reached that

town with not enough money left in his pocket to pay for a bed at the

Bay Horse inn; where he put up。  But telling the landlord that he

expected work at Marshall's; and seeming to be a respectable young

man; the landlord trusted him; and he was so fortunate as to obtain

the job which he sought at Mr。 Marshall's; who was then beginning the

manufacture of flax; for which the firm has since become so famous。



Mr。 Marshall was at that time engaged in improving the method of

manufacture;*

 'footnote。。。

We are informed in Mr。 Longstaffe's Annals and Characteristics of

Darlington; that the spinning of flax by machinery was first begun by

one John Kendrew; an ingenious self…taught mechanic of that town; who

invented a machine for the purpose; for which he took out a patent in

1787。  Mr。 Marshall went over from Leeds to see his machine; and

agreed to give him so much per spindle for the right to use it。  But

ceasing to pay the patent right; Kendrew commenced an action against

him for a sum of nine hundred pounds alleged to be due under the

agreement。  The claim was disputed; and Kendrew lost his action; and

it is added in Longstaffe's Annals; that even had he succeeded; it

would have been of no use; for Mr。 Marshall declared that he had not

then the money wherewith to pay him。  It is possible that Matthew

Murray may have obtained some experience of flax…machinery in working

for Kendrew; which afterwards proved of use to him in Mr。 Marshall's

establishment。

 。。。'

and the young blacksmith was so fortunate or rather so dexterous as

to be able to suggest several improvements in the machinery which

secured the approval of his employer; who made him a present of 20L。;

and very shortly promoted him to be the first mechanic in the

workshop。  On this stroke of good fortune Murray took a house at the

neighbouring village of Beeston; sent to Stockton for his wife; who

speedily joined him; and he now felt himself fairly started in the

world。  He remained with Mr。 Marshall for about twelve years; during

which he introduced numerous improvements in the machinery for

spinning flax; and obtained the reputation of being a first…rate

mechanic。  This induced Mr。 James Fenton and Mr。 David Wood to offer

to join him in the establishment of an engineering and machine…making

factory at Leeds; which he agreed to; and operations were commenced

at Holbeck in the year 1795。



As Mr。 Murray had obtained considerable practical knowledge of the

steam…engine while working at Mr。 Marshall's; he took principal

charge of the engine…building department; while his partner Wood

directed the machine…making。  In the branch of engine…building Mr。

Murray very shortly established a high reputation; treading close

upon the heels of Boulton and Wattso close; indeed; that that firm

became very jealous of him; and purchased a large piece of ground

close to his works with the object of preventing their extension。*

 'footnote。。。

The purchase of this large piece of ground; known as Camp Field; had

the effect of 〃plugging up〃 Matthew Murray for a time; and it

remained disused; except for the deposit of dead dogs and other

rubbish; for more than half a century。  It has only been enclosed

during the present year; and now forms part of the works of Messrs。

Smith; Beacock; and Tannet; the eminent tool…makers。

His additions to the steam…engine were of great practical value; one

of which; the self…acting apparatus attached to the boiler for the

purpose of regulating the intensity of fire under it; and

consequently the production of steam; is still in general use。  This

was invented by him as early as 1799。  He also subsequently invented

the D slide valve; or at least greatly improved it; while he added to

the power of the air…pump; and gave a new arrangement to the other

parts; with a view to the simplification of the powers of the engine。

To make the D valve work efficiently; it was found necessary to form

two perfectly plane surfaces; to produce which he invented his

planing machine。  He was also the first to adopt the practice of

placing the piston in a horizontal position in the common condensing

engine。  Among his other modifications in the steam…engine; was his

improvement of the locomotive as invented by Trevithick; and it ought

to be remembered to his honour that he made the first locomotive that

regularly worked upon any railway。



This was the engine erected by him for Blenkinsop; to work the

Middleton colliery railway near Leeds; on which it
