Parkinson’s Patent Perfect Vise

Welcome to part I of this potted history of the quick-release woodworking vice – a history that will culminate with the venerable and arguably never-bettered Record 52 1/2 vice.  Many of us own or have used one of the quick-release woodworking vices, but I wonder how many people are familiar with the history?  We have much to thank a chap called Joseph Parkinson for.  Parkinson did for vices what Leonard Bailey did for bench planes: he pioneered a design that become a de-facto standard and dominated the market for well over a century.

Parkinson’s Patent Perfect Vice

David Fell’s father worked at the company founded by Parkinson and has created a web site that provides some background information on the business (J Parkinson and Son, Shipley, Yorks) and about the man himself, who was clearly an impressive chap:
http://www.parkinsonshipley.co.uk/

The company survived into the second half of the 20th century and according to the account in a booklet produced to celebrate the centenary of its founding (summarised in the site above), Parkinson invented his quick release vice in 1884, having come a cropper in his dealings with a customer who had copied the design of his ‘handy’ line of vices and then started up in competition with him.

Having had his fingers burned once before he registered patents for the new invention in multiple countries during the next year or so. Here is the US patent (1886): US361445

…and here is a picture of the workings taken from the Canadian patent (this patent shows a picture of the joiners vice, omitted from the drawings in the US application)

Unfortunately the text of the Canadian patent is hand written and not very well scanned which makes it almost illegible so we have to go just on the drawing for details.

c.f Fig 6 for the woodworker’s vice: there is a spring loaded flat bar (k) which engages with a groove in the base of a half nut (N). The bar is attached to a lever (L) next to the vice handle and when squeezed the lever causes the flat bar to pivot downwards, taking the nut with it and disengaging it from the screw. In this position the vice moves freely back and forwards.

Although not completely clear in the picture, it is almost certain that the spring that holds the bar/nut in the engaged position for the woodworker’s vice is directly under the half nut, rather than next to the trigger (which is the familiar arrangement today).  C&J Hampton (Record) – who copied Parkinson’s QR mechanism – used the same arrangement up until the early 1930s:

d
old C&J Hampton (aka Record) vice – you can just see the spring through the hole in the under carriage

C&J Hampton eventually found a better solution and moved the spring to the inside face of the vice.  This meant that the half-nut used in the QR mechanism could  be housed in a removable casing so it could be extracted for cleaning without first having to remove the vice from the bench.

In turn Parkinson adopted this improvement in their vices:

this is the QR design that Parkinson eventually settled on: the large watch spring on the inside face of the jaws applies twisting pressure to the flat bar.  The flat bar engages with a notch on the underside of the half-nut which is pushed on to the screw until the lever connected to the bar is compressed, whereupon the half nut disengages and the vice jaw can moves freely back and forth.

Having invented an effective quick-release mechanism Parkinson was able to use a buttress thread for the screw. These threads apply a strong force in one direction at the expense of their effectiveness in the reverse direction (not a problem when the vice can be opened without the screw using the quick-release lever).  See, for example, toothpaste tops for an example of this type of thread:

Parkinson called the new range of vices the ‘Patent Perfect’ range, and in the terminology of the day it was an ‘instantaneous grip vice’ – the earliest reference to the term we have settled on in recent times ( ‘quick release’) was about 15 years later, in a patent filed by an American.

The vices were clearly successful (and well built), since the frequently turn up for sale on ebay UK in working condition today. An early model is shown above (note that the vice runs on parallel cast ‘sliders’ rather than the round steel guides in later vices from Record et al.  Note also the unconventional (for the UK) spelling of ‘vise’ – no doubt to contrast this range with his older range of vices.

There are a number of references to Parkys in books aimed at headmasters and teachers – perhaps their adoption in classrooms helps explain why there are so many around.  Mind you they also had a decent production run – the distinctive design shown above, with the unadorned front jaw and cast steel sliders, was made at least until 1930 (more on that later).

Type study

We know the Parkinson perfect instantaneous grip was made from 1884/5 onwards, the earliest picture I can find of the woodworkers’ model is from the Charles Nurse 1891 catalogue1)available, with other catalogues, from taths.org if you sign up as a paying member, and it shows a design I have not seen elsewhere:

Image

…  this appears to be  the very first model and we’ll call this the ‘mark I’ (1885 onwards).

The ‘mark II’ model has cast iron sliders and a distinctive front face design with “Parkinson’s Patent Perfect Vise” cast in a semicircle around the handle can be seen in this 1905 catalogue by Melhuish:

Melhuish’s No. 15 Catalogue of Woodworkers’ Tools

Thus the best we can say is about Mark II is is it was introduced before 1905.

The catalogue below shows the Mark II being sold alongside the Record pattern  that would eventually displace it (note that by this time Record had adopted steel rods – an improvement over fragile cast iron sliders):

Image
John Hall catalogue ~19272)archive.org has this catalogue dated as 1910, but there is no date on the catalogue and I do not think it can really have been produced before 1927, which is when Miller Falls introduced their electric drills (see p. 80 where they are listed

The 1930 catalogue entry below shows the mark II Parky but (this time with two screw holes rather than three).  It is likely that this is one of the final outings for the old Parky ‘steel slider’ design:

Image
Buck & Hickman 1930

As you can see, Record undercut the price of the older Parkinson mark II vice and, since theirs was an improved design, it is likely that they would have quickly eroded Parky’s sales. Indeed, by 1930 much of UK QR vice production – and there were numerous competing makers – had switched to using a Record-like design.

We’ll call the mark III version of Parky’s range the ‘Record Pattern’ – as we can see from the B&H catalogue above, this version was introduced alongside the traditional Mark II cast steel slider version.

This version has a newly designed front face, as is shown in their 1937 catalogue 3)The catalogue was actually published in 1940, but a cover note explains it is a reprint of their 1937 edition but with updated prices.  Note that the tables have truly turned and at this stage Parkinson are making an exact copy of their competitor’s model, going as far as licensing the ‘screw and nut cover’ idea from Record (more on that in a subsequent post):

1940 catalogue

By 1935, at least according to the Buck & Hickman’s catalogue below, the Mark II pattern was no longer available.

B&H 1935

So in summary, the timeline seems to be roughly:

  • mark I: 1884/5 initial quick-release model introduced – see Charles Nurse catalogue above
  • mark II (introduced between 1891-1905) new design of front jaw (see photo of vice painted in red above).
  • mark III (~1930) – Record Pattern introduced (steel sliders and newly designed front jaw – see advert immediately above).  This was initially sold alongside the mark II until the earlier model was discontinued in the second half of the 1930s)

Before Joseph Parkinson’s quick-release mechanism could conquer the world of woodworker’s vices he had to overcome the competition.  There are two notable examples: The ‘Syers’ standard instantaneous grip vice and the ‘Riley’ instantaneous grip vice.  Before we get to those we will take a brief detour into US made vices in the next post4)incidentally much of the information in these vice-related posts is summarised from information that was first published (by me!) on www.UKworkshop.co.uk – a tremendous forum if you are interested in woodwork

1 thought on “Parkinson’s Patent Perfect Vise”

  1. Very interesting post. The owner of our last house left a brute of a heavy vise when they sold their house about 12 years back. I’ve kept the vise and just made a workbench. On cleaning the vise I’ve discovered the lettering only last week. it’s a parkinson perfect 16 and works beautifully. From your description it appears to be the mark 3 version. Looking forward to the next post.
