Manufactured by Frick Co. - Waynesboro, Franklin County PA

Abstract: This invention relates to that type of sawmill head-blocks wherein an under dog is provided as well as an upper dog, so that the log or board may be held at the bottom as well as at the top. The object of my improvement is to so arrange the under dog that it wilt be entirely out of the way and to provide a strong and compact mechanism for operating it. My improvement consists in arranging this under dog in a chamber or recess formed in the head-block, and combining it with an eccentric and eccentric-rod for raising and lowering it. Claim: The combination, substantially as before set forth, of the saw-mill head-block constructed with a chamber, the under dog pivoted to the head-block within said chamber, the eccentric in said chamber above the dog and journaled in the side of the head-block, and the eccentric rod and strap for connecting the pivoted dog with the eccentric.

Manufactured by Frick Co. - Waynesboro, Franklin County PA

Abstract: This invention relates to that class of traction-engines in which the traction-wheels are driven from the crankshaft of the steam-engine through the medium of a train of gear-wheels of which the driving-pinion on the crankshaft can be shifted, so that it may either be thrown in gear with the next wheel or disconnected therefrom, according as the steam-engine is to be used for propelling the machine or for driving other machinery. Our invention consists, mainly, in fitting a part of the said pinion in a guide, one or more on the fly-wheel, which guides also serve as clutch-teeth for driving the pinion, so that the usual driving-spline on the crankshaft may be dispensed with. Claim: The combination, substantially as before set forth, of the flywheel constructed with a ring-flange, and with guide-ribs on the interior side of said flange, and the shifting-pinion constructed with wings which are engaged by said guide-ribs.
