Re: other loads was D8 Bulldozer as a Flat Car Load

Nice photos!

The dozers shown are D7 types with LeTourneau blades. They had an odd (for Caterpillar) rounded hood that tapered and curved towards the back. No other Cat had such a hood. They are about the same size as a D8, but were lighter and less powerful. Both were used extensively in WWII.

I do agree that the LeTourneau scraper shown would be an excellent item for some manufacturer to model (they are available in 1/48 scale). These seem to have been the most successful of many scraper types of the period. They are mechanically complicated and a challenge to model well. All “actions” were activated by cables driven by winches on the tractor. They came in several sizes. The basic scraper “bowl” could be pulled by either a crawler tractor or an integral 2-wheeled tractor (the “Super-C Tournapull”).

Bill, Dennis, Dan, Folks,

Lots of interesting photos out there. I agree with Dennis that there usually isn’t a lot of cable/chain for example for WWII era loads, but there usually is some. With respect to dozers, here is a photo from the Farmall factory of artillery tractors  and cranes loaded on last (note that to the right, they are in motion being loaded!)

Another attached photo (Delano, I think) circa 1944 show new dozers with attached blade assemblies.  Cat D6 or D7 I’m guessing?

What I would love to see is a LeTourneau towed scraper model in HO. Similar to the one in the attached photo from the Signal Corps Archive.

From spending all lunch browsing the web, all I can say is don't confuse modern practice with what was required in our era. Photos of modern loads show little or no blocking, but lots of cable tie downs. Steam era practice was lots of custom fitted blocking and few if any tie downs. I recall the dozer that fell off the flatcar in Downers Grove, causing a spectacular wreck on the Q three track mainline, fell because someone forgot to nail the blocking in place. Nothing was said in the ICC report about tie downs.

I'm certain that "S" inside a hexagon is a foundry stamp. From your information I
conclude that ASF holds the patent.

From my limited info, Symington-Gould is the only foundry I could find that uses an
"S" inside a hexagon.

Tim

I'm not sure about the Symington-Gould foundry stamp, but it is ASF (American Steel Foundries) that is stamped on the upper left truss-member. In the center is stamped Vulcan, which was an ASF trade-name. There is a patent date of 10-6-96 on the left diagonal. This date routinely appears on ASF Andrews and Vulcan trucks of the teens and twenties, and reflects the original patent awarded to one J S Hardie, the rights to which were later acquired by ASF. The sideframe in Hardie's patent bore only a passing resemblance to an Andrews or a Vulcan; it was the removable journal box bolted into the pedestal jaw that was patented.

BTW, based on the CBCs, the "Andrews" and "Vulcan" trade names seem to have come into play in about 1909 and 1916 respectively.

Also note that, on this truck, the top chord appears to be a U-channel, while the rest of the truss is T-shaped. I assume this was a short-lived transition on the way to the full U-channel version. I don't think this "mixed truss" arrangement was in any way common, but I have seen a couple of other examples. There is a Gould-manufactured "Vulcan" sideframe advertised in the 1909 CBC that clearly has both U- and L-section elements.

Re: D8 Bulldozer as a Flat Car Load

So apparentlythis is NOT the one now offered by Rio Grands Models.

The photo on the EH webside does show the undersized tracks that haunted the earlier Canon models kit ... I think they are the same. It’s odd that they did such a good job on the engine and chassis of the tractor, but goofed-up badly on the tracks.

However, the GHQ tractor is a great, and far better, model of this same prototype.

Largely true, with exceptions … like logging railroads which moved a lot of equipment around by rail over their own systems. The early tractors were usually purchased with only basic equipment, usually including winches.

Blades, scrapers, rollers, etc. were then purchased from any of a number of after-market suppliers. This lead to a LOT of variety, and some real "Rube-Goldberg" monstrosities.

Any thoughts if any dozers were equipped with the after market blades at the Cat factory? My gut feeling is the tractors came naked, and after market accessories like blades and rippers were added by the purchaser.

Usually the case until after WWII.

Just an aside, I have memories of when the Chicago expressways were excavated during the fifties, and recall cable rigged dozer blades with the block mounted on the top of the nose over the radiator, but never saw one with a full overhead frame.

I recall seeing LeTourneu overhead-rigged cable blades on Cat tractors with rear winches in the 1950’s. By then front mounted winches were the preferred system. Such had the winch mounted on the front below the radiator (chin), with the cable running up to a set of sheaves mounted above the radiator (forehead), then down to the blade. This was a much simpler and more compact arrangement, but largely limited to just worknig a front blade. In a few more years the hydraulic accessories would take over the market.

It should be noted that early tractors were not so often used as bulldozers. They mostly pulled graders, elevating graders, scrapers, rollers, rippers, and wagons. The utility of the dozer blade was not so obvious at first. As the front mounted blade became the norm for much earthmoving, the tractors were modified to match and the front mounted winches became common.

If you’re interested in such machines, investigate the Historic Construction Equipment Association (HCEA). They have national and regional meets around the country, and a website < http://www.hcea.net >. Their meets are lots of fun … giant “sandbox" for a weekend, with all sorts of old machinery rooting, digging, pushing, plowing, and hauling earth, accompanied by matching sights, sounds, and smells. Tremendous action everywhere, but with almost nothing being accomplished!

Nowadays one rarely sees a “naked” crawler tractor … they are still occasionally used to pull scrapers as they have more “pull” than a wheeled tractor, but they’re too slow for most current practice. Today crawlers are mostly seen as bulldozers, rippers, and scraper-pushers. Lately there are a bunch of big 4-crawler "rubber-band” tracked machines making inroads since they are midway in performance (“pull” vs. speed) between metal-tracked machines and weeled tractors.

Re: D8 Bulldozer as a Flat Car Load

Daniel A. Mitchell
 

Mostly correct. Various tractos could have blade made by many diffeent maufacurers. The design of the blade often was determined by the way the tractor was outfitted … mostly either front or rear mounted winches. And, while hydraulics were around, very few tractors used them until well after WWII (early rubber hsoes and seals were very poor and troublesome).

Many/most such early tractors had rear-mounted winches that were suitable for operating towed scrapers. Thus, to use this configuration with a front blade, some method to route the cable forward was needed, This could be in a side-mounted tube, or an overhead gantry. The very popular LeTourneau blades used such an overhead structure. These are modeled by both GHQ and Artitech. Both are suitable for any period from WWII to the 1970’s … they lasted a long time.

Once proper flexible parts became available (1960’s) hydraulics almost totally took over from cable-control motions. Still, the old machines continued in use for many years.

One thing to keep in mind is during this era, Caterpillar built the tractor, but the various blades were after market parts, likely installed at the distributor that sold the machine. So, if these are supposed to be a shipment of new machines, rather than company MOW equipment, they would be shipped without blades and all that overhead cable rigging.

I “think” this is/was the old Canon kit, which may have ended up with RGM. The few photos i’ve seen all exhibit the same qualities and problems. The body was quite nice, but the tracks were very poor, and undersized. perhaps RGM has corrected this?

The “RD” denoted a tractor equipped with a gasoline engine, as opposed to the "D” tractors that were strictly Diesel. The RD8 is otherwise the same tractor as the early D8.
