This hammer is in my shop in Haliburton and sorry but I'm not into video. Here is a picture of the rear cylinder and the valve/ air intake ports.The leather flap/reed valve at the top allows air to exhaust before the compression stroke begins, roughly half of the cylinder volume is used to push the ram down. On the down stroke of the rear piston the only new air introduced is through the 4 plugs at the bottom, removing them or drilling out one (as I have done, top right plug) to the correct size keeps the front ram from topping out. Depending on the wear of the front ram (which does leak to certain extent) you can adjust as needed. The front ram is 6" x 7" and is adjusted with shims of wood on either side using the large u-bolts.

The mill sold this hammer last year and it now resides in Haliburton.

Just an update if anyone is interested. The ram weight is 78 lbs (actual weight) and the hammer was patented in early 1890's by a Melvin Yeakley of Ohio. (Pat# 568395) The patent I came across was not for this exact hammer but for one that would have had improvements over the original design. It runs very well after being rebuilt and will be used daily. And no it's not for sale.

The only marking on the hammer is a small plate with the previous owners company name. (Hayes steel products machine #91)

Yes that's the one.

Not for sale. Just rebuilding it.

Ontario Canada.

Just wondering if anyone knows anything about this brand of hammer or can point me in the right direction . Searched for information but came up with nothing. It is a pneumatic hammer with a (40lb +-) rectangular ram. Any help would be greatly appreciated.
