Dalton Adding Machines

The Dalton Adding Machine Company began operations in Cincinnati, Ohio in 1902. The principle product was then a ten key printing adding machine. This was probably the first ten key adding machine and featured a two bank keyboard and not the four bank keyboad number arrangement that most modern five finger touch systems use. Early printing adding machines were called "listing machines". All of the Dalton machines were key set with a hand crank or, later on, motor operated. In 1923, the company boasted that it offered a total of 152 models, divided into different groups accoring to construction, adding or listing, calculating, bookkeeping, statement preparation, fractional capability and British currency capacities.

Sometime around 1927 the Dalton Adding Machine Company was purchased by the Burroughs Corporation and Burroughs simply discontinued all the Dalton models. One might say they purchased and then killed their competitor.

In addition to the machines we have posted here we do have a few in "as found" condition as well. We also have some water mount decals we had made up for the Dalton and for other early adding machines and typewriters. They are available on a first request basis until we are out of stock.


Early Dalton 10 Key Adding & Listing Machine serial #7843

This very early Dalton adding and listing machine features plate glass all around and it is in exceptional condition. It has not been restored and is in its original condition. We would grade it at 2,2. It looks great and is in good working order. It only needs a new ribbon to be operating like it did when it was new in 1904. The only flaw we can find is that the back glass plate appears to be a little loose.

While we have had several Daltons over the past 30 years or so, this is without a doubt in the best original condition as well as the earliest Dalton we have ever offered.

Our price includes free packing and shipping anywhere within the USA and there would be an additional $200 international shipping charge (due to weight and size) for anywhere outside of the USA.

Dalton 10 Key Adder serial# 40556

This Dalton 10 Key Adding Machine has been fully restored. All the casting had been sandblasted with apricot pits and repainted using 3 stage automobile paint to closely resemble the original Japaning finish.
All the artwork had been carefully and professionaly duplicated and covered with at least three clear coats. The mechanism was cleared with high pressure air and also pressured oiled with a very light mechanical oil.

The last patent date shown is 1912 and we would estimate this machine was manufactured in the 1912-1915 time frame. When we fully restored this machine some years ago it was functionally properly but now while the parts and gears do move it only functions sporadically and needs an adjustment to funcion properly and as intended. If you actually wanted it to print out you would also need to add a new ribbon which one can usually get at Staples or Office Max from a cash register or computer printer replacement ribbon. Also, it does not have ribbon covers. That is why we have given it a "3" rating for function. Our current condition rating estimate is 2,3.

There is free shipping anywhere within the USA via US Parcel Post and an additional $100 to ship anywhere outside of the USA via US Priority International mail.

Dalton Plate Glass Listing Machine serial #9742

This machine dates to around 1904 and when considering that the first machines didn't show up until 1902 this particular one is truly an early model. It has beveled plate glass all around. The plate glass was first used by Burroughs around 1900 and it was purely a marketing feature to show the customer that the gears were cranking and that the machine was truly calculating the answer and not being fed the correct answer by a con man salesman. See the Burroughs story. This machine has been restored and we estimate its condition rating as a 2,2. The machine does appear to be working as intended but there is no ribbon.

There is free shipping anywhere in the US and an additional $80 to ship it overseas via US Priority International.
