Scheblers of that style with minor differences were used on a world of different vehicles and engines. Yours is a very early one,with that late looking pipe bushing in the intake reducing it down to the size of that double 90 manifold,I would guess it's a later adaptation. Hard to say what it originally came out on.

A Schebler model "D".

 

As Sagefunds says, they were used in several applications in the automotive, agricultural or stationary power industries and were popular in the aftermarket as well. The  friction-held "guillotine" throttle mechanism on this one was not well suited to the constant opening and closing of an automotive application and was probably used in a marine setting where you typically adjusted your speed a few times per outing, or a very early agricultural application where they were still employing a "hit & miss" type governing system to control the engine speed rather than relying on the carburettor.

The 1910 Fuller I used to have originally used that style 'gate valve' throttle. The car was missing its original carburetor when I got it, but original literature showed what it had had originally, and I was able to find one for it. So they were used on automobiles and still used at least as late as 1910. That said, they were not really popular as automobile carburetors, and other types, marine and industrial, did seem to use them more often.

Although there are similarities, that one is not quite the same as the one for my Fuller.

Cushman grain binder engine used them. Although this one is definitely reconfigured for a different application.

The Schebler models D and M, as mentioned earlier, were used on a large group of passenger, motorcycle, truck, tractor, agricultural, industrial, and marine applications. 

 

The model D came in 6 different physical sizes.

 

The model M came in 3 different physical sizes.

 

The earlier versions have no markings that will help with absolute application.

 

By the late 1920's, at least some of the tractor versions had the identification number STAMPED on the bowl. An example would be DX-320 used on a Hart-Parr.

 

Many of these carburetors have NO throttle; the throttle valve being incorporated in the intake manifold.

 

The "gate valve" throttle was early; not sure exactly when it was discontinued, but would GUESS very early 'teens.

 

The design is interesting in that the throttle casting could be interchanged with the air valve casting; thus the carburetor could be configured as either an updraft or sidedraft unit.

 

When rebuilt with a new air valve and air valve spring, these carburetors are some of the very best and most reliable of the early carburetors. Once engines with higher RPM became more common, these carbs became less useful.

 

Finding literature on these things is more difficult than winning an argument with the IRS!!! I have repeatedly begged for photocopies from O.E. factory parts manuals, with very little success. The original Schebler literature covers the 6 "standard" model D carbs, 3 Hart-Parr, and a couple of John Deere. The model M is simply a model D with a check valve.

 

There is another carburetor labeled "Acorn" which is identical to the model D, excepting the name. I do not know the relation of the Acorn to the Schebler.

Is it for sale ?   Can use it on a Sears Restoration project.
