SPECIFICATION forming' part of Letters Patent No. 539,319, dated May 14, 1895.
Application filed April 26, 1894. Serial No. 509,087. (No model.) l
' a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to head-blocks for vsaw mills and consists in certain improvements in the construction thereof, as will be hereinafter fullyset forth and pointed out in the claims.
The invention is illustrated in the accom` panying drawings, as follows:
Figure 1 is a side View of a head-block embodying my invention,with parts broken away to show interior parts and with the base A in vertical longitudinal section on the line 1 l in Fig. 2. Fig. 2 is a plan of the base A, with parts broken into section. Fig. Sis a side elevation of the base A. Fig. 4 is a transverse section of the base A on the line 4 4 in Fig. 8. Fig. 5 is a like section on the line 5 5 in Fig. 3, with the knee and rack-bar shown in dotted lines. Fig. 6 is a detail View showin g the construction and operation of the rackbar. Fig. 7 is a View, partly in section andl partly in elevation, from the line 7 7 in Fig.-
6. Fig. 8 is a perspective view of the auxiliary rack-bar D. p
A is the base of the block; B, the knee; C, the setting shaft; O,thepinion on the shaft, C; D, the rack-bar carried by the knee; and D', an auxiliary rack-bar contained within the rack-bar, D.
The rst part of the invention relates to4 the.'
construction of the base, and the improvements in the construction thereof are as follows:
The web, ct, ofthe two sides of the base is made serpentine in horizontal section as seen clearly in Fig. 2. The object of this is, rst, to give the greatest possible strength with a minimum of metal, and, second, to afford spaces for the ends of the cap holding bolts, a?, and the operation of the nuts thereon, as is seen in Figs. 3 and 4. The top of the base has ahorizontal flange capping'the serpentine portion and this in turn is faced with steel plates, a', which are held in place by counter- Vsunk bolts, a2, which pass through said plates and horizontal flange into a space in the serpentine sides where they are secured by nuts, and these plates form the upper lip of the knee grooves, b. (See Fig. 4.) The knee grooves, b, and the tongues on the knee that slide therein'become worn, and means should be provided to take up this wear, and this is effected by the use of the face plates, a', for
when the parts become worn, the plates can f be removed and the top surface of the base on which they rest can beplaned off sufficiently, and the caps be replaced.
The sides of the base are made with shaft openings therein sufficiently large to allow the pinion, C', on the shaft to pass through them, and a bushing, A, is fitted therein to form a journal-for the shaft. The object of this construction is to facilitate the putting `middle portion of the carriage are put in place, and the shaft, C, is then lput in place. The pinions are then put on, each end of the shaft and brought to place between the walls of the base and keyed by keys, c, and the bushings not yet in place are put in place. Thus it will be seenthat by having the shaft openings in the Walls of the base large enough to allow the pinions to pass through them'and filling said openings with bushings, A', access can at any time be had to the keys, c.
My remaining improvements relate to the construction of the rack-bar in the knee, and the object thereof is to provide means for taking up wear of the cogs, and prevent lost motion.
In Fig. 6, the arrow on the pinion, C', shows IOO its direction of motion, when the knee is moved forward. lBy observing Fig. 7, it will be seen that the rack bar, D, has a central longitudinal groove in which is contained the auxiliary rack-bar, D. By observing Fig. 8, it will be seen that the bar, D', has at its forward end a slot opening, d', and at its rear end an eye, e', at right angle to the direction of the slot, CZ.
Vhen the bar, D', is in place in the bar,D, it is held at its forward end by the pin, d, (see Fig. 1,) which passes through the slot, d', and it is held at its rear end by a screw threaded pin, E, which extends from the bar, D, and passes through the eye. e', and by nuts, e e, on the pin, E, the bar, D', can be held firmly against longitudinal motion or it can be ad.-
the two bars out of alignment, and when the pinion is moving the knee forward, it bears only on the cogs of the bar, D, and when movthe face plates, a', onthe top of said base;
and the bolts, a?, passing through the. face plates and horizontal iianges on the base with their nuts `placed in the indentations of the side walls, for attaching said plates to said base.
2'. Ina saw-mill head-block, the combination with the knee; of the rack-bar, D, carried by said knee, and having a longitudinal central groove in its face; an auxiliary rack-bar contained witliinsaid groove; `and `means for adjusting the auxiliary barlongitudinally of the inain bar, substantiallyasand for the purposes set forth.
In testimony whereof I aix mysignature in presence of two witnesses.'
