Inventor W. H. Ward

The Ward Axle, Brake & Coupling Company was an ambitious, short-lived 1880s railroad technology startup based out of Monongahela City and Pittsburgh, Pennsylvania.
Managed by inventor W. H. Ward, the company sought to solve the two deadliest mechanical crises facing late-19th-century rail travel:
inefficient manual hand-brakes and lethal link-and-pin car couplers.
A "Power Brake," Not an Automatic Brake
"the Ward Brake is not an automatic, but a power brake."
Complete Engineer Control (Forward & Back)
The brake was entirely under the control of the
engineer (or trainmen) at will for either forward or back,
the same as by the best of air or known vacuum brakes."
High Efficiency for Freight Use Mr. S.W. Haines,
the Superintendent of Motive Power and Rolling Stock,
gave it a stellar review: "for a freight brake with wheel shoes
he could recommend it as the best he knew of."
The Million-Dollar Contract: On March 1st (circa 1885), the
company signed a massive $1,000,000 syndicate deal
with wealthy Pittsburgh capitalists and railroad executives.
The Moving Halt Engine moving at a "lively speed" with
full steam actively left on. The brake completely overpowered
the engine's propulsion, bringing the train to a smooth stop without
shutting off the boiler steam.
The Grade LockTrain positioned on a downward slope where gravity
alone would cause a rollout.The brake was locked down, and the
engineer opened the throttle completely.
The engine could not move a single inch against the brake’s
holding power

Harry Hayward, manager for the Reliance Foundry Company Monongahela Pa.
The inventor of a new Mine car car wheel which promises to revolutionize the manufacture of that branch of the pit car industry.
While the principle is applicable to all wheels and pulleys, the most promising field for its practical development is in the coal car, where the constant friction in the bearings makes the renewal of the car wheel a frequent occurrence and a heavy expense.
The patents on the wheel are owned jointly by Harry Hayward and David Gregg. of Monongahela
The peculiarity of the new wheel is due to the method used in the construction of the bearings. It is as in such a manner that when the bearings become worn they can be taken out and replaced by new ones and the wheel will be again as good as new at about one-fourth the original cost.
Special arrangements for lubricating the wheel are also provided for and this feature will greatly reduce the wear on the bearings. The new style wheel can be produced at the same cost as the old style ones hence sold at the same price.
The saving is in the cost of renewal which has to be frequently made, and with the new wheel is only one-fourth what it now 's with the old style ones in use.
The first shipment of the new product went forward yesterday, an experimental order of twenty wheels being sent to the Humphries Coke works at Vance's Mills It is confidently believed that in a short time the wheel will be in general use in mines and that the old style ones will be regarded as too expensive for economical use.
Track shives are also made in the same manner. It will be even more economical in this branch than in the wheels themselves, as the shives can be cast of much harder metal and therefor wear much longer.

1st Removable Wheel Bearing
The 1904 Haywood-Gregg patented design introduced a removable wheel hub and integrated, sealed bearing assembly, whereas earlier industrial mine car wheels relied on a primitive, single-piece cast iron construction
The design utilized a closed-hub system with a sealed end cap. This served a dual purpose: it acted as an internal oil/grease reservoir that could lubricate the wheel automatically for weeks, while completely sealing out damaging coal dust and grit.
Mine car Wheels were replaced with new ones and the worn wheels were scrapped before this invention
