GUSTAVUS ZSOHEGH, OF INDIANAPOLIS, INDIANA.
IMPROVEMENT IN HEAD-BLOCKS FOR SAW-MILLS.
Specification forming part of Letters Patent No. 145,712, dated December 16, 1873 5 application filed November 8, 1873.
To an whom it may concern:
Be it known that I, GUSTAVUS Zsonnon, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and val uable Improvement in HeacbBlocks for Saw- Mills; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a plan view of my head-block. Figs. 2 and 3 are side views of the same. Fig. 4 is a sectional view of the same. Figs. 5, 6, and 7 are detail views of the same. Fig. 8 is a top-plan view of the same.
This invention has relation to headblocks for sawmills; and it consists in a certain novel construction of parts, whereby the knees can be adjusted singly or together, and moved either by means of a vibrating lever or by means of a crank-handle, as will be hereinafter explained.
The following is a description of my improvement In the annexed drawings, A A represent two head-blocks, which will be mounted on a log-carriage in the usual manner, and which have knees B B applied to them, and moved by means of screws 0 G. On these screws bevel spur-wheels a a are keyed, which engage with bevel-wheels b b on a horizontal shaft, D. The shaft D is supported by bearings D D extending out from the ends of the headblocks, and on one of its ends a crank-handle, J, is applied, by turning which the knees B B can be rapidly moved back and forth when the wheels c b are in gear. The wheels I) b are applied on their shaft by means of a feather and groove, so that they always turn with it, but may be moved endwise on it and disengaged from the wheels a a. By means of yoked levers c c, which are acted on by springs, (shown in Fig. 7,) the wheels I) b are held in gear with the wheels at a. E E represent two bearings, on which are secured a vertical semicircular guide, E, in which a lever, F, is applied. This lever F has its bearings on an axis, 3 and is constructed with toothed segments F F, which are concentric to said axis, and which engage with beveled spurwheels 9 g on the shaft D. The spur-wheels g g are constructed with ratchet-teeth e on their backs, which engage with ratchet-teeth on the faces of wheels d d on shaft D. The wheels 9 g are applied on their shaft by means of doubleheaded keys j j, (shown in Fig. 4,) which allow these wheels to turn freely on their shaft, but prevent them receivingendwise movement. The ratchet-wheels d d are prevented from turning on their shaft by means of the keys j 7', but are allowed to receive endwise movement. The tubular hubs of the ratchet-wheels d d are received into cups H H, and surrounded by springs s s, which act to keep these wheels in gear with the wheels 9. G G represent pins, which pass through the wheels 9 g, and bear against the inner faces of the wheels 01 d. These pins G G are acted 011 by means of finger-keys G G, which press the .wheels d d away from wheels 9 g, and thus disengage the ratchet-teeth of these wheels.
It will be seen, from the above description, that when the wheels 9 g d d are disengaged the knees B B can be moved rapidly by turning the crank J also, that either one of the knees can be moved independently of the other. It will also be seen that when the wheels 9 g d d are in gear the knees can be moved by vibrating the lever F.
What I claim as new, and desire to secure by Letters Patent, is
1. The wheels d d g g, applied on the shaft D by means of double-headed keys j j, the wheels (I d being acted on by springs s s, and the wheels 9 g engaging with segments F F on lever F, in combination with saw-mill headblocks, substantially as described.
2. The pins G G and their finger-keys G G in combination with the wheels (1 d g g and the springs s s, substantially as and for the purposes described.
3. The combination and arrangement of the wheels at b, yoked levers 0, wheels at d g g, and segments F F on lever F, and crank J on shaft D, as described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
GUSTAVUS ZSOHEOH. Witnesses:
CHARLES GoULoN, AnoLrn HARDER.
