UNITED STATES VILLIAM H. SNYDER, OF WAYNESBOROUGH, PENNSYLVANIA.
SAW-Mlm. SET-WORKS.
SPECIFICATION forming part of Letters Patent No; 316,299,V datedApril 2l, 1885.
' Application tiled October 18, 1884. (No model.)
' to be 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 the feed mechanism of saw-mill head-blocks whereby the headblocks are advanced across the log-carriage to feed the log or stick of timber across the line of the saw each time preparatory to sawing a board from the log.
My invention consists of certain novel combinations, with such feed mechanism, of mechanical devices for operating it automatically at the required times, which combinations are specifically pointed out in the claim at the close of this specification.
In order that my invention may be clearly understood, I have illustrated in the annexed drawings, and will proceed to describe,a form thereof as applied to a common style of sawmill.
Figure 1 is a plan view of so much of a sawmill as is sufficient to clearly illustrate the nature and application of my invention. Fig. 2 is a longitudinal sectional elevation thereof. Fig. 3 is a transverse section.
The same letters of reference indicate identical parts in all the figures.
A refers to a portion'of the log-carriage upon which a common head-block, B, is mounted in the usual manner, and which runs on the ordinary ways, C O. A rack .on the under 'more pivoted pawls, h h,which rest on ratchetwheel F. Spur-wheel G is engaged by a rack, I, the stem or'shank I of which is arranged in suitable cross-guides, i, of the log-carriage.' This shank of this cross-sliding rack is connected by a pin, i', to a lever, K, which is fulcrumed on a cross bar, 7c, of the log-carl riage, and carries at its extremity, on its under side, a horizontally-disposed anti-friction roller,A k. The lever K is so applied and formed that its antifriction roller is below the frame ofthe log-carriage. Y
Some distance in advance of the saw, and between the ways of the log-carriage, is placed a fixed longitudinal rail, L, of considerable length,andhavingalongitudinal slotorgroove, Z, T-shaped in cross-section. A cam-plate, M, is mounted on this rail L in position to operate on lever K by its camway m, which is formed by the ribs m m on its upper surface. The camway m is a straight-way made flaring at both ends, so that the anti-friction'roller of lever K can enter it with ease from either end. The cam-plate is clamped to the rail L by a clamping bolt, l', which projects up through the slot in the rail. This clampingbolt passes through the cam-plate' near one end, its axis intersecting the center line of way m, and has a round stem so that the camplate can be turned on it, in order that` the camway may be turned from a position parallel with the ways of the log-carriage, Ywhere it will have no effect on lever K, to such angular position as may be required to enable it to vibrate the lever K through suchy an arc as will cause the head-block to be advanced by the feed-gearing the necessary distance for sawing boards of a given thickness. The camplate is constructed with an arc, m2, marked with a scale, and a sliding pointer, m3, is mounted in the slot Z of rail L. The lines ofthe scale represent inches and fractions thereof, and are so placed that any line opposite the pointer will indicate the exact thickness of the boards that `may be successivelysawed from the log so long as lthe cam-plate'occupies that position. The scale and pointer thus afford the means for adjusting the cam-plate speedily and with precision. Thev arc'm2is slotted, so that a second clamping-bolt, Z2, may be conveniently applied to securethe camplate to rail L.` The cam-plate is made longitudinally adjustable on rail L,'in .orderthat its position may accommodate itself. to the travel of the log-carriage, which necessarily changes with the length of the logs. The camplate should be fixed in such position that immediately after the log-carriage in retrograding has carried the log entirely beyond the I OO saw the anti-friction wheel k of'lever K will enter camway m, and the retrogression of the carriage must continue until said anti-friction wheel k has traversed the Whole length of said camway. The lever K is thereby turned, as indicated by dotted lines in Fig. 1, and the rack I slid so as to turn spur-Wheel G and arm H to move the pawls h 7a on ratchet-wheel F. As the logcarriage returns, lever K is turned back by the camway m to the position it is shown in by full lines in Fig. 1. This return motion of lever K Vmoves the crosssliding rack I, spur-wheel G, and pawls h in areverse direction, so that the pawls will now turn ratchet-wheel F and the feedshaft E, to which it is secured, whereby the head-blocks will be laterally advanced to feed the log the required distance.
My devices for automatically operating the 2o feed-gearing may be applied to various kinds on carrying a pawl for turning said ratchetwheel, the cross-sliding rack and the lever for sliding it both mounted on the log-carriage, and a stationary camway for vibrating the said lever.
In testimony whereof I afx my signature Ain presence of two witnesses.
