The Tobin bolting system looks for all the world like Ansley H. Fox's Patent No. 714,688 granted Dec. 2, 1902, assigned to Philadelphia Arms Co. though PAC didn't use it. I've always suspected that patent wasn't used because it was applied for Jan. 17, 1902, when Ansley was still employed by Winchester Repeating Arms Co. The patent for the Philadelphia Arms Co. locks was done with Ansley's brother, Harry Hunter Fox's name and the PAC ejectors patent was done under the name Max Wirsing, both of Baltimore.
