The Following is an explanation of what history items have been located from


The Ashton Valve Company

Boston Ma.


The Ashton whistle drawings, bills of material, and foundry specifications were recovered from 14 rolls of 35 mm filmstrip. These film rolls appear to be dated to 1937 they seem to be a complete copy of all drawings on file at that time. A complete cataloged list of all Ashton whistle drawings and bills of material is made available through the web site only, and prints of all are available by mail order only.

The search for whistle drawings


This project is being conducted on my own time.


No bills of materials survive save 2 or 3. So the search began by sitting down to the aperture card machine and seeing what drawings survived. The aperture card file first began in the 1970s and at that time all surviving paper and cloth drawings were photographed and place on negatives. After searching through 40 years worth of drawings about 750 whistle drawings were located and retrieved to paper and scanned to printable files. They are all made available through the web site by mail order only. (ONLY PARTS MARKED WITH ( D&PC ) IN FIRST COLUMN ARE AVAILABLE) (all prints are on 13 X 19 quality paper. (warning if you order a drawing of a nut expect a drawing of a nut)


After cataloging these drawings it was apparent that there is a percentage of drawings missing. Luckily the parts card file was found to be better than 99% intact. Searching the part card file produced a more complete catalog of the Crosby whistle product line.


In the whistle parts warehouse web page

This is a large page. If you are on dial up service give it time to load. Saving this would be a convenience.


Each drawing was catalogued into the list. Information from the drawings on the list in columns are:


     part number

     pattern number

     drawing or trace date

     whistle size

     cup style


     special notes


The part cards added:


     part card dates

     replaces part number

     replaced by part number

     material composition


The part card date in the list relates to the replaces and replaced part numbers. If a replaced by part number is listed then the date is the date the part was superceded. The replaces part numbers on a number of cards have dates, but a new column was not added for them. If a replaces number is shown and no replaced by then the date shown is the date the part was instituted.


In all cases if a drawing was missing I included as much information as possible on the catalogue listing from the part card. (the additional is in available blank spaces on that row) A good number of the so called missing drawings may not actually have ever existed in the first place. Many specials and prototypes may have only had hand sketches for parts that traveled with the orders paper work.


Column Key for the Bell/Code column


The column marked bell/code contains a sorting number, which in the case of the chimes is the cup number( 1,2,3 )

4 is a code for organ whistles

5 is a code for compound auto whistle valves

5.5 is code for globe valve type whistle valve

6 is code for automatic compound whistle valves

5 and 6 seam to blend a bit

7 is a code for hand and electric operated whistle valves

8 is code for balanced piston whistle valves

9 no nine

10 long bell commons built after 1915. 6 inch 8 inch and 10 inch size

11 is a code for a whistle recording device. (dont know if ever built)

no code = Both drawing and part card do not contain a description as to what whistle they went too, also in the case of electrical components shared for automatics


Many parts have multiple listings of used on whistles. The list in this case has a part row for each whistle it was used on and the size and code columns altered for each different whistle. By coding and multi entries, performing a search by size column then code column and then by part description gives the sorted list that you see here. The sorting gives us a rough bill of materials for each item over the years. Some shared parts with other Crosby products may still be missing.


Crosbys part numbering system began in 1900 with the part number matching the drawing number. Hence a retrace of then current product drawings began, this I believe continued for 10 years. The old drawing numbers are crossed out on the part cards. Some of the old numbers have been included in the list, but a portion of them I did not record and is incomplete as yet. If a listing in the Catalog has an entry in the old drawing number column then that part was created before 1900 with the drawings showing the date that it was traced from the old prints. References to the old drawing number on part cards for the most part ends around 1910, and all part numbers after then being new parts.


It seems that the old Crosby common whistles were not traced to new drawings and allowed to fade away. Chime whistles being the focus of whistle business with others were traced to new drawings. Of course new developments also appear as years go by.



( Many more products are underway, give me some time. )



Crosby Foundry Specifications web page


The foundry specs were found in an engineers notebook that miraculously survived from the twenties. Five note books one of which contained information on the foundry specs current in1923. The current system of material identification was first issued in 1939, and had most of the early compositions dropped from the listing. This engineer also did some work on the whistles and has a section devoted to his dealings at that time with the whistles.
