OF FULTON, NEW YORK.
IMPROVED HEAD-BLOCK FOB. SAW MlLLS.
Specification forming part of Letters Patent No. 40,248., dated October 13, 1863.
,Blocks upon Saw-Mill Carriages; and I do ,hereby declare that the following is a full and exact description of the same.
The nature of my invention consists in adapting to the head-block of a saw-mill carriage a chain propelled by a lever, and chainwheels, as hereinafter described, designed to obviate the irregularities and inconvenience occasioned by the screw commonly in use also, in adapting a dog and rack to such headblock in the manner hereinafter described, for the purpose of protecting the head-block from injury by the concussion of heavy logs or timbers against the same.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
I construct 'my head-blockas to size and shape like those in ordinary use.
I adapt to the head-block a flat chain with double or single links. I cause the chain to revolve on wheels having in their perimeter cogs adapted to the links of the chain. I cause the chain to revolve by means of a lever, to which is attached a ratchet-dog moving a ratchet-wheel. Above the ratchet-wheel I construct a circular index, to which I adapt two stops, adjustable at pleasure, designed to regulate the thickness of the board or timber while in the process of being sawed. To the ratchet-wheel I attach a female coupling, as shown at P on the accompanying drawings, about four inches in diameter. Into this I insert a male coupling. This coupling is held firmly in'its place by means of two dogs at tached to a knuckle-joint. I
The object of attaching the female coupling is for the purpose of connecting and disconto the log for the purpose of taking off a slab of equal thickness at each end from a log of greater diameter at one end than the other. The knuckle-joint I expand or contract by means of a rod drawn by a screw, the latter being propelled by a hand-wheel, as shown at 1' in the drawings.
1 construct adjustableboxes, as shown at K, for the purpose of keeping the chain taut and taking up any slack that may be occasioned by friction or use.
To give additional strength to the headblockand preserve the chain from .strain, I
construct a rack, into which is inserted a dog, as shown at L.
This improvement in the use of a chainmeans of the couplings. I Thecoupling is designed to connect two head-blocks constructed as above described by means of a shaft or rod. These new in use are connected .by a band or belt- My invention obviates the irregularities of a belt movement. I mark upon :the index inches. andpa'rts of inches by adapting the stops to any given measurement. Each full sweep of the lever will propelthc stakeB a regular and uniform distance.
On the accompanying drawing, letter A represents the frame. Letter B represents the stake. Letter 0 represents the chain.
- Letter d represents the ratchet-wheel. Letter e represents the chain-wheel shafts. Letter f representsthe lever. Letter g representsthe circular index. Letter h represents the stops on the index. Letter '5 represents the groove in hand-wheel. LetterK represents the movable boxes. Letter Z represents the dog for the stake. Letter 0 represents the carriage for the head-block. Letter P represents the female coupling. Letter 4 represents the sleeve-containing pin passing through the rod ofv the male coupling to which knucklejoint is attached. Letter 1' represents the hand-wheel and nut. Letter s represents the ears that hold the sleeve to hand-wheel. Letter t represents the groove in hand-wheel.
2. The combination-and arrangement of the Y female coupling P, sleeve q, ears s, handwheel 1', groove t, and knuckle-joint or their equivalent, constructed and arranged reletively with each other, to operate as and for the purpose described ME LANOT HON W. DAN KS.
