Work Apron

次回、この記事の日本語版を投稿します。

As anyone who has worked in Japan knows, the vast majority of companies have uniforms.  And even for those smaller privately owned shops and craftsmen,  there is the work apron known as maekake in Japanese. 

Worn around the waist and tied off in the front, work aprons not only help to keep the user's clothes clean, but also serve an important advertising function.  Let's take a look at this tidbit of history, a maekake which dates back around 60 years.162

Work aprons are used by a wide variety of shops, and are certainly not limited to bicycle shops.  Typical work aprons are made of a coarse indigo colored woven fabric with the proprietor's shop name, address and advertisement printed in white.  Let's start at the top and work our way down.

At the top in Kanji it reads "Yamaguchi Bicycles and Maruishi Bicycles".159

Printed in the middle of the apron are the emblems for Maruishi and Yamaguchi bicycles along with the silhouette of a bicycle.  Note the detail in the silhouette, full chaincase, headlight, front fender ornament, rear rack, stand and even a generator on the rear wheel.

Printed in large characters just below the bicycle emblems and silhouette is the name of the bicycle shop which reads Azuma (Bicycle) Shop.
161

Underneath the shop's name is the address and telephone number.
The telephone number "333" reflects just how old this work apron is, a three digit telephone number.  But, what a lucky telephone number three "3's"!

I ran a quick search for these maekake and was surprised to see various old one's up for grabs on Ebay.  Appears these maekake are gaining popularity. One can even have a custom printed maekake made from a company called Anything (Japanese website).

スポークベル (後半 ロッド式)

I'll be back with another English post soon until then stay trued and happy wheels.

現代では滅多に見かけない回転式ベルについて以前紹介したことがありますが、
前回の記事では、
それよりもっと珍しいケーブル式スポークベル(下記)について取り上げました。

ロッドブレーキは、ケーブル式ブレーキの元祖であることと同じように、
ロッド式スポークベルは、ケーブル式スポークベルの元祖です。
今回、取り上げるのは非常に珍しいロッド式スポークベルです。

ケーブルの代わりにロッドがあり、後は基本的に同じです。
ロッド式なので、実にシンプルで機能的な構造です。

シンプルで機能的で良いですね。
ケーブがないので伸びないし調整不要。
それは古い自転車の魅力の一つ、頑丈でシンプルなのでローメンテです。

Spoke Bell (Part 2: Rod activated type)

次回、この記事の日本語版を投稿します。

In the previous post I mentioned that I have written about bicycle bells in the past, with a focus on revolving bells,  and we took a look at another kind of bell rarely seen today the cable operated spoke bell shown below.

It was also mentioned in the previous post that just as rod brakes preceded cable operated brakes, so too did rod operated spoke bells precede cable operated spoke bells.  Thus, in this post we will take a look at a very rare rod activated spoke bell.

The basic opertion is exactly the same only instead of a cable, rod linkage is utilized. As can be expected, the mechanism, right down to the adjustment rod linkage, is ingeniously simple, yet functional.

Here is the lever used to activate the spoke bell.  Compare this with the cable activated spoke bell lever. (Click on photos to enlarge.)

Note the rod linkage and the thin rod, at the bottom of the photo, which runs all the way down to the bell and is connected to the spring held clapper.

At the normal resting position the spring held clapper is away from the spokes.P1290872

Note the rod attached to the spring held clapper.P1290859_2

Pressing downward on the lever pulls a rod connected to the spring held clapper up and into the spokes.

Simple, functional and effective.  No cable stretch or adjustment to worry about.  That is one of the things that I like about these old bicycles, not only are they strong and sturdy, but they are virtually maintenance free!
