VCCA Home Forums TECHNICAL - 1945 AND NEWER 1946-1948 47/48 jacks part 2

I think Kevin has been moving into the new home stead for some time now. My interest in in the 48 jack

Gene, you said " some '53/'54's has a roller on the ratcheting part that ran on the jack post". So, is that picture one of those?



Bruce, the picture in the '48 accessories book you posted, looks like a dead ringer to this. Note the corners on the base. So, question is, WHEN did this jack become the one supplied with the car. Perhaps early '48, mid '48, late '48, or '49???
Another ?. The lower lift height. In '48 it is stated at 7 5/8". '49-'54 is stated at 6". Questions??????

The picture is of the original correct jack from my 1950. I can't remember for sure as to where the location of the roller was on SOME 1952-1954 jacks.

The patent number on my 1950 jack is 2,433,537.-same as the earlier post.

The base in the ad picture above looks smaller than mine. Also mine has no bottom plate or "legs" just a single stamping.
The jack in the picture is in the 1948 parts book umder the part number shown....I believe that is a 1948 jack. That number is also in the 1947 accessory list.

From 1949 Engineering;
The tool equipment supplied with the 1949 models consists of an improved bumper jack and handle. The redesigned bumper jack has a larger base for greater stability, and a heavier column for increased strength. The base is now 8" square, where as it was 7" in 1948. The minimum height of the jack has been reduced from 7 5/8" to 6", to accomodate the new bumpers. The column mount is now ofset from center of the base, and the instruction tag specifies the proper position for operation of the jack. The jack handle is designed to serve also as a wheel wrench and hub cap remover. The hammer,wrenches, screw driver, pliers,and tool bag formerly supplied, are eleminated for 1949.

So Gene, To me, that seems that the '48 "supplied" jack is not the one shown above. It may have been the "accessory" jack, but not the standard. The '48 standard is going to look more like Dick's '47. Also confirmed earlier by Johnny. That Engineering Manual seems to bare this out. Reading the text, it also confirms that the lower height was indeed 7 5/8 for '48.

As to the patent #. Dick's jack had "patent applied for". Ed's believed '48 jack had 2433537 on it. Since that number was assigned or approved on December '47, that would indicate, to me at least, his jack was made after that date. That patent number carries through for many years.

I agree with all the above.

I have 3 different jacks ariving with in the next 2-3 weeks..One may arive today...2 of the 3 have the patent# 2433537..The last jack I will receive has been deamed to be the correct 48 jack,this jack comes from a "VCCA member in the know"
If I end up with the 48 accessary universal jack shown in the acc.book,I will be happy and have documentaion as needed for judging.You I will keep you all up dated!

Received the 1st one...It is not working and has no base but has many of the same thing as does Dicks and Eds..The roller underneith the bumper support is new...Same as Genes



The W



The spring at the bottom of the shaft



and the same patent#



Thoughts

Looks like a mirror image to Gene's '50.

Wondering, how much space is left on you jack wall of fame?

The Jack in the Box"41"jack"is now on the wall,the 40 is in its own box ...Would that be UPS???...Sounds like a jack trade to me?Will the Chef have the correct 48 jack soon?

Gene, we now know that the jack patent was issued to M. G. Ward in Dec. '47. I'm going out on a limb and speculate that he is the designer of the '46 through '54 and maybe later. Their is a "W" stamped on these jacks and that's all. Could we assume that GM and maybe others licensed the design and made the jack themselves. I can not find any more info on Mr. Ward. Thoughts.

Makes sense to me

No doubt!!

I only hope it is the "standard" jack that would have been in the car when new. At least, that's the one I want.

Good hunting!

I am sure GM made no jacks. With the W stamped Ward made the jacks or another company with the W being the first letter in the name.

I learned something today. There is a roller on my jack as was pointed out by the aroww a while back. Never looked that close at the jack before. That means 1949-1954 jacks are the same.
My jack also has the stamped W.....by the looks the jack was used only a few times.

Then I checked out the nice 1955 jack I have. Has patent pending and a stamped W.....and the rolller.

I can't get at my '57's jack but hope to later in the week.

You have to give this thread credit. It has stayed on subject through the many posts.

That is because, for me at least, to clear up the questions that were never really answered back in 2007. Hopefully we will stay on task until the mystery of the '48 jack is cleared up.

Wonder why only a "W" on the jack and not a name or company???

Just kidding.


So their must have been enough of a change after '54 to apply for a new patent.

Let's not give up soon,I have 2 more jacks to show

Bruce, and others, look at this. 48 jack, 2003 thread.

Same questions in 2003. I wonder if we will get any further this time around?

Saginaw Division of GM made jacks but they were a different type than being discussed. They were sold through United Motors Service.

I think we are getting closer...Too bad all the pics in the old posts are lost

Hey Bruce, I just finished reading that earlier thread, and low-and-behold, look who was the last poster in that thread.

With your persistence, we will get some answers THIS time around.

What do you think, possibly a match? The base that is. Note the circle in the front. The jack that is marked as 1950, pretty sure it's the universal, same as '48 universal. One in the same.

I got the second jack.Looks just like Genes
. The base is 8x8.I would say the base in the pic looks like the accessory jack , doesn't look square?

I remembered to take a look at the jack in my 48. Has the W and patent # 2,433,537, and the spring in the bottom. Looks just like the picture of the 50 jack. Just about everything is original on my 48, other than the engine has been changed twice according to the paperwork I have. Of course I changed out the wiring harness a couple of years ago.

Hi Keith,
Does your jack base look like the picture above? If yes, do you see any numbers on the bottom? Like maybe 2400235??? If it looks different, how about a picture???

Russell, did you buy that base I do not see it on e-bay any more???
