791,767 Jun. 06, 1905 Push-drill Zachry T. Furbish Philadelphia, PA This patent takes the the #40 and 41 Yankee drill and adds a spring tension adjustment to become a #44.
814,529 Mar. 06, 1906 Push-drill Zachry T. Furbish Philadelphia, PA Further refinement of patent 791,767. The patent pictures the top lid hinging off but I do not think that was ever used. The 1912 North Brothers catalog shows the #44 with the open magazine facing the chuck so when inserting a new bit the magazine isn't dumping it's contents into your hand.

842,107 Jan. 22, 1907 Removable-Blade Screw-Driver Selden G. North Philadelphia, PA The invention is for a replaceable blade screwdriver with blade storage in the handle. The blade storage is mentioned in the Patent but is covered by a different Patent Interestingly the Patent for the blade storage 858131 by Henry J. Aichele was filled on the same date as North's Patent but wasn't granted till six months later.Sold by North Brothers as the #65, came with 4 removable bits and storage in the handle.Sample marked ,'North Brothers MFG.Co. PHILA. PA. U.S.A. PAT.NOV.2,97-JAN.27,01 PAT.JAN.22,1907. The 1897 Patent593157 and the 1901 Patent 666507 both by Zachery Furbish.

858,131 Jun. 25, 1907 Cap for Magazine Tools Henry J. Aichele Philadelphia, PA Removable cap with a retainer that projects enough when the handle is inverted to allow it to be removed by hand.
This Patent for the blade storage was filled on the same date as Selden North's Patent 842107 for a removable blade screwdriver but wasn't granted till six months later.Sold by North Brothers as the #65, came with 4 removable bits and storage in the handle.Sample marked ,'North Brothers MFG.Co.

864,633 Aug. 27, 1907 Screw holder for drivers Thomas J. Fegley Philadelphia, PA North Brothers No. 15. One of these appeared in a Martin Donnelly auction. This is Fegley's third patent on this date. 864,631 and 864,632 are related to an ice cream freezer.

902,387 Oct. 27, 1908 Detachable-blade screw-driver Thomas J. Fegley Philadelphia, PA An improvement on Selden North's Patent 842107.By adding a spring in the blade track of the handle , the replaceable blade is held securely in place,Norths approach to the problem was to slightly bend the prongs of the replaceable blade, thus keeping it in place by friction.Sample marked ,'North Brothers MFG.Co. PHILA. PA. U.S.A. PAT.NOV.2,97-JAN.27,01 PAT.JAN.22,1907.

906,902 Dec. 15, 1908 Speed-change gear George O. Leopold Philadelphia, PA The competition heats up as North Brothers enters the 20th century with novel approaches to the breast drill. The mechanisms on the North Bros. breast drills are still considered the best by many.

948,850 Feb. 08, 1910 Chuck Thomas J. Fegley Philadelphia, PA
952,320 Mar. 15, 1910 Chuck Thomas J. Fegley Philadelphia, PA Used in the "Yankee" series of eggbeater hand drills. The jaws are kept spread apart by springs which are hidden from interference by bits or other objects pushed blindly into the chuck. The chuck is tightened by rotating the shell so that the threaded spindle proceeds inward along the chuck centerline. The attorneys were Howson & Howson, which firm exists to the present day.

977,957 Dec. 06, 1910 Ratchet Mechanism for Screw-Drivers, &c. George O. Leopold Philadelphia, PA
979,939 Dec. 27, 1910 Spiral tool-driver Thomas J. Fegley Philadelphia, PA The patent drawing shows the #75 Yankee "push brace". Fegley and Leopold's goal was to make a drill to be "....used in places difficult in access but which can be reached by a comparatively long tool, such as in car work, cabinet work, etc....." They also positioned the ratchet selector at the top where the operators hands were. And they installed a heavier, three jaw chuck. In the 1912 catalog they explained why they called this tool a brace. "It excels a bit brace in its greater rapidity and convenience in the lighter work ordinarily done by brace."

1,015,235 Jan. 16, 1912 Gearing George O. Leopold Philadelphia, PA This patent is for a speed change device which also serves as a spindle lock when changing bits.
1,021,538 Mar. 26, 1912 Gearing George O. Leopold Philadelphia, PA The same goal as Leopold's patent 1,015,235. It may be that the orientation of the shifter on the drill is different.

1,023,023 Apr. 09, 1912 Gearing George O. Leopold Philadelphia, PA The #50 drill is shown in the drawings. This patent is for a device that will lock the shaft at any point for the removal and insertion of bits. The #50 I own will not do that. The only patent date on that one is the 1897 patent.
1,033,712 Jul. 23, 1912 Chain Drill George O. Leopold Philadelphia, PA Improved, inexpensive feeding mechanism that allows the slack of the chain to be taken up by turning the spindle until sufficient pressure is exerted to engage the ratchet mechanism.

1,059,132 Apr. 15, 1913 Means For attaching handles to tools Thomas J. Fegley Philadelphia, PA Utility drills like this one benefit greatly from means to store and protect the bits used to bore holes. A further benefit is the ability of the manufacturer to ship the drill in a smaller, less expensive box made possible by the break-down feature of this handle. The patent attorneys were Howson & Howson, which firm exists to this day.

    Vise George O. Leopold Philadelphia, PA  
1,132,320 Mar. 16, 1915 Vise Thomas J. Fegley Philadelphia, PA Vise is designed to be used as either a bench vise or used as a clamp on a machine tool such as a drill. Utilizes a broad bearing surface and can be turned and locked one in position.
Applied to the Yankee No. 1992 which also carried their later patent 1144828.

1,236,848 Aug. 14, 1917 Clutch mechanism George O. Leopold Philadelphia, PA Rather delicate-looking shift mechanism for the North Bros. line of non-ratchet two-speed hand drills. This is _not_ the five-speed mechanism for the large breast drills, which added a ratchet to their speed selectors. Instead, it is an alternative mechanism used with the 1445 drills. US Patent No. 1,015,235 was the second alternative, the one actually applied to the two speed, non-ratchet 1445 drills.
