One of the criteria you can use to measure success is if something stands the test of time. The Ace Aceliner model 502 was made for over 50 years with almost no changes. I think that qualifies as being very, very successful.
If you have one of these fasteners the reasons for its longevity become readily apparent. Solidly built, surprisingly heavy-duty, and dependable as death and taxes. If that’s all the Aceliner [note 1] had going for it you wouldn’t be surprised by its success. However, add in the unique styling and thoughtful ergonomics and what you end up with is one of the best looking, best built staplers ever made.
There were a total of four plus versions of the Aceliner manufactured. The first versions all have the same specifics. Each weighs 1 pound 4 ounces and measures 7.75 inches long by 1.7 inches wide by 2.7 inches in height. They are made with all steel parts which according to literature was “triple-chromed”. There are also two rubber feet and a plastic handle. The handle was made of a plastic known as catalin as was the decorative plastic disc inside the push-rod head [note 2].
The 502 was advertised, and the bottom of the stapler states this as well, as needing Ace no 2025 or 20253 staples. However, the no 2025/20253 staple is exactly the same size as a standard-size staple so standard staples will work just fine. The magazine will hold a full strip of 210 staples. There is also a sliding anvil that will allow you to change between permanent and pin clinches. And of course you can use the Aceliner as a tacker by rotating the base 180 degrees.
One of the questions that often comes up in regards to the Aceliner is how to load it. The Aceliner is a rear-loading machine. To load, simply pull very slightly up and then out on the rear push-rod head. The head is the part on the rear that is a chrome round ring surrounding a colored plastic disc. Pull the rod all the way to the end and then swing it upwards. You can then insert your staples. Very easy once you do it once or twice. There is a button on each side of the body that when depressed allows you to lift the handle as you would with a standard stapler. However, you cannot load staples this way. The purpose of this feature is to allow access to the inside in order to clear jams or fix any issues that come up with the internal mechanism.
The Aceliner was advertised starting in 1941 through at least 1992. These were still being manufactured in 2001 and into the 2000’s but there is very little information about this. In total there were four plus known versions of the Aceliner. You can determine which version you have by using the following information:
- Version 1 (1941 – 1961) rounded smooth top, front of body is blank, has three patents listed on bottom of base plus “OTHERS PEND”
- Version 2 (1962 – 1971) rounded smooth top, “ACE” etched into front body, has four patents listed on bottom of base plus “OTHERS PEND”
- Version 3 (1971 – 1992) scalloped top with rectangular inset with in script molded into it. “ACE” etched into front body. Along with this, later models of this version will state “USE ONLY ACE NO. 20253 STAPLES”.
- Version 4 (approximately 2000’s) same styling as v3 but weighs slightly less at about 1 pound
I’ve also composed the following chart showing which handle colors are known to have been available in which years [note 3].
Chart Notes:
a) the color names used in 1941 were how they were originally listed by Ace. By 1945 all colors were identified by one word descriptions.
b) year gaps simply signify that I could find no advertisements, catalog listings, official Ace literature, etc. that mentioned available colors.
c) color gaps signify only that no reference could be found to that color in any literature, etc. for that year. In other words, it’s not only possible, but likely, that in 1949 you could purchase an Aceliner with a mahogany, green, or black handle. But nothing official has yet been seen to corroborate this. However, you probably wouldn’t have seen a grey handled Aceliner until 1961.
UPDATE: In August 2021 I published my newest book Staplers, Stapling Machines, & Paper Fasteners Volume 3: Ace Fastener. In this book you’ll find a greatly updated write-up on the history of the model 502 Aceliner which includes info on all TEN versions of this stapler!
Patent and Other Information:
- Aceliner Stapler Instruction Sheet
- Patent 2059020 Stapling Device (filed 01/15/32, granted 10/27/36)
- Patent 2066157 Stapling Machine (filed 01/28/33, granted 12/29/36)
- Patent 2107169 Stapling Machine Core (filed 08/27/34, granted 02/01/38)

- Patent 2832959 Stapling Device (filed 08/25/55, granted 05/06/58)
- Design Patent 127378 Stapling Machine (filed 03/26/41, granted 05/20/41)
Notes:
- The correct spelling for the no 502 is “Aceliner” not “Ace Liner”. This two-word version probably came about due to the inscription on the bottom of the staplers. ACE was placed above LINER but that was simply due to space limitations.
- Even back in the earlier 20th century there were different types of plastic. It’s something of a pet peeve of mine when someone says that old plastic is “bakelite” simply because its old. It seldom is. You especially see this on online auction sites. It has pretty much the same standing meaning-wise as words such as “rare”, “antique”, “vintage”, and “art deco”. All these terms along with “bakelite” are essentially meaningless on auction sites.

I’ve got three Aceliner staplers I bought together as part of a larger lot of used staplers. They don’t match any of your four versions, and appear to fit in between versions 3 and 4. The engraving on the bottom says “USE ONLY ACE NO. 20253 STAPLES MADE IN USA” but unlike my other Aceliners, there is a seam in the staple tray on the front (below the “ACE” inscription) and not on the underside of the staple tray. Also, the push rod is not held captive like my older Aceliners, but is easily removed when one is loading staples. There are some other differences, but those are the main ones.
I don’t have a scale handy, so I cannot confirm that these are the same weight as your Taiwan-made version 4 (although the redesign appears to use less metal), but they are marked as made in the USA. I’ll try to take some photos so you can see the differences.

The 20253 staples thing is from a late model version 3. I also have push rods that can be completely removed but the jury is still out on if that is purposeful from Ace or not. I’d love to see the pics. The seam on the front of the magazine is very likely a late change to the model 3 as it would allow the use of cheaper pressed metal designs. We’re all learning together and I love this kind of feedback!

Here are the photos (if this lets me post a link): https://imgur.com/a/GB2mAtL
I kept my five Aceliners in the same order in all the photos; from left to right, version 1 in black, early version 3 in tan, and three of the late version 3 (version 3.5?) in walnut, black, and a darker tan. I discovered there are number codes in the side of the staple tray, visible once the top is opened. There’s no code on the version 1, “471” on the early version 3, and “389”, “389” & “278” on the other three. These are constant with a month & year date code, but this is too small of a sample to be certain of that.
Engraving aside, these are the differences in the three “new” version Aceliners:
1) Staple tray construction, with the “interlocking puzzle piece” seam on the front, and no seam on the underside.
2) Different rubber feet, attached with a different sort of rivet.
3) Hole on the side of the staple tray, letting one see if staples are loaded.
4) Pusher rod is not captive. The track that allows the captive pusher rod to be pulled up and out of the way when loading staples is completely missing.

It’s impossible to say without seeing it, but the two most likely issues are a spent spring or a tiny divot in the rail. Try a little machine oil on the rail and see if that works. You may need to replace the spring and if so you will likely have to procure a donor machine and take the spring from there.

I have an Aceliner 502 which worked fine with standard staples for about 25 years until 1 day the staples and the end of the push rod refused to move all the way forward. I can force the push rod forward without the staples, but not with the staples. The push rod is removable.
I’ve checked numerous times, even probed with dentist’s tools, there is nothing blocking the staples.
Is it possible that a buildup of the staple adhesive is the problem?
Coincidently, another brand stapler that uses the same staples which I’ve always used is exhibiting the same problem. Any ideas why and how to fix it?

Without seeing the actual stapler it’s difficult to diagnose. I don’t believe it is caused by the adhesive. However, consider changing staple brand to one of the more mainstream brands like Swingline. These older staplers were designed with slightly thicker wire staples than you currently find, especially in the off-brands. You can also press the button on the side of the body to lift the handle and take a look inside to see if there is any debris or stickiness on the rails.
