Many people have fond memories of the Bell Punch Company.  Some reminiscences about the technical aspects of the ANITA calculators appear on other pages.  On this page are general  reminiscences about the company.


Penny Harrison, formerly Titheradge:
    "My father Philip Titheradge worked as Salesman / Sales Manager/ Area Manager for Sumlock in the 1960's-1974.

    During his time he worked out of Clerkenwell Road and then Finchley/Whetstone, (finishing at Northway House) and covering Herts/Bucks/Beds,

    He was recruited from his former job as a door-to-door Hoover salesman – he had gone to a call and the lady of the house invited him back that evening to speak with her husband.  This was quite usual and Dad thought nothing of it until, when he went back, the man of the house, Mr Derek Jones, said "my wife tells me I am to give you a job because you're too good a salesman to miss out on" and Dad said "fine, can I have the Hoover sale as well?" (and got it).

    I remember many Christmas dances… especially one at Lowestoft which must have been in 1971 or 2 when the cabaret artiste sang "Hey big Spender" to the MD and sat on his lap to my great (teenage) delight!

    I wish I could remember more names – Tony Woodiwiss was one of his colleagues, I recall (because of the unusual name).

    In the summer holidays he would take me out on his rounds provided I sat quietly in the car and read while he and his "demonstrator" went in to the office/factory to make the sale.

    One summer holiday (1973) I worked on the switchboard at Northway House and was very amused when two pay packets came through for "P Titheradge" – I know which one I wanted!

    I remember him passing out in Wall's when being shown the sausage production line, and being fascinated at RAF Cranwell…and so much more. Especially the winter of 1963 when he dug himself in and out of snowdrifts to carry on making the sales.

    He did very well for the company and for himself. Our family were very lucky through that as we could afford a continental touring holiday every year; I went to private school from 13 and of course we had use of the company car.

    Sadly, he and his colleagues were "made redundant" in 1974 on the company's being taken over although I was led to understand they were one of the first groups of people ever successfully to fight and win compensation for this.

    Dad regularly brought calculators home – they were reminiscent of sewing machines in size, weight and cases – and let me "play" with them and I was allowed to stay up late for the elections of the early 60s as he and his team were to be seen in the background calculating the results!

    I would be so happy to hear from anyone whose parents worked with Dad – and happy for you to put them in touch." [You can get in touch via this site].



John Clements:
    "I read with great interest on the reminiscent page the account by the daughter of Philip Titherage.

    So here is my story.

    I joined the bell punch company in 1958 as a mechanical calculator mechanic.  I worked out of the Clerkenwell office.  The managers of the department were Ted Grist and Len…  Also Cyril May who I had got me the job.  (He was my commanding officer in the Air training Corps Squadron that I belonged to in Richmond Surrey).  Along with; Tony Bell, the diminutive Arthur…. Tony Rocco, et al (the years have dimmed my memory for names but I can still see their faces).  I worked on the range of mechanical calculators, Sumlock, Plus etc.  The Electro/mechanical range up to the SUMLOMATIC.  We were a happy team of mechanics.  Having received our daily quota of machines to repair and service we retired to the cafe around the corner on Clerkenwell Green for breakfast.  We worked on our own and when we had finished our quota we were allowed to go home.  Becoming a skilled mechanic I very often returned around midday to my home in Richmond.  I travelled all over London and became very familiar with it.  I remember one company I visited was just across the street where I lived!

    At that time I became interested in amateur radio and after attending night school I eventually obtained my amateur radio certificate in 1962—The year of the big freeze.  I also at that time contracted TB and the company very generously paid me a full wage and held my job for the three months while I was in hospital.  It was also around that time that the company was developing the Electronic side of the business and I pestered the life out of my bosses to be allowed to transfer over to that side of the business.  I was accepted and was given a three years part time day release course at Southhall college in Electronic servicing.  It was a 5 year course but I managed to complete it in three.  During the time up to the closing of the company I worked on the complete range of electronic desk calculators produced by Sumlock Anita Ltd.  I was transferred to the Ealing branch under the sales manager Bill Snowball.  In the Anita service dept. My boss was George Dunkley who had worked on the development of the Anita's at Uxbridge.  Other engineers were: Dave Woods, Ernie Batson,.  That is where I met my wife to be Norma Samson.  It was during this time that the company took on a German machine made by NIXDORF called the "CONTI" I was one of the few in the company to be trained on this machine.  I was chosen because of my mechanical and electronic experience.  I remember it had a ferrite ring memory.  Unfortunately mechanically it was not the pinnacle of German Engineering by any means.

    In 1968 I got married and moved yet again to the Norwich branch and that is where I met Philip Titherage.  As he was now the regional manager covering our area of Norfolk, Suffolk and Cambridgshire.  He only made brief visits to the sales department though so we didn't see much of him in the service department.

    Colleagues in Norwich were; Mike Cole, (Supervisor), Norman Williams, Bob Doig, Mike Mallet, Mac Bottolf, Tony Bell. Chris Woods etc.  At the shutdown of Sumlock Comptometer, and after 16 years with Sumlock, I was made redundant and spent a few months unemployed but eventually returned to work alongside my former pals.

    On the close down of the company, each of the 32 branches were offered a buyout.  Mike Cole and the others struck out on their own.  The business became a very successful independent entity under the name of SUMLOCK BONDAIN.  So now we could engage in the service and repair of all types of electronic equipment.

    I left in 1978, after the breakup of my marriage, to work abroad in Saudi Arabia and Bahrain.  That was where I saw the last Sumlock machine I was to see in the flesh so to speak.  It was in the company owners office, sitting in an honoured position on a window sill.

But then that's another Story!
