JAMES A. HOLFORD OF GUINSVILLE, INDIANA. Letters Patent No. 60,374, dated December 11, 1866.
--f "dige Scintille referrer tu in tlgisn tttert zitcut ma mating part nf its sane,
TO ALL WI'IOM IT MAY CONCERN:
Be it known that I, JAMES A. HOLFORD, of Guionsville, in the county of Dearbormand Statepof Indiana, have invented a new and improved Circular-Saw Mill; and I do hereby declare that'the following isa full, clear, and exact description thereof, which will enable others skilled in the art to make' and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a plan or top view of my improved saw mill; and
Figure 2, a front elevation of the same.
Figure 3 is a vertical longitudinal section of the carriage, taken on the line :c x, iig. 1.
Figure 4 is a vertical cross section of the same, taken on the line y y, g. 1.
Figure 5 is a detailed sectional view, taken on the line y y, fig. 3. i
Similar letters of reference indicate like parts. i
's This invention relates to certain improvements in circular saw mills by which the whole machine will work automatically in all its parts, and `by which the log when placed upon the carriage iscut into boards of the p requisite thickness, withoutrequiring the least attention from any men. ,i .i The invention consists, first, in a combination of certain parts of the machine by' whichanautomatc setting motion is attained, that is, the log, after a board has been cut off, is shoved forward the'thiekness of the board by the machine itself. This setting apparatus can be so regulated that any desired thickness of board may .be cut and set. V Second, my invention consists in an automatic feed motion, by which the motion of the carriage is reversed as soon as the leg is cut, the carriage then returns to it starting point, when the log is adjusted by the'aforesaid setting motion, and the machine is then again reversed so as to propel the log against the saw.
The driving pulley A, which is supported by the standardsa, standing on the floor B of the machine, drives by means of the belt bythe shaft C, to which thc saw D is attached. .Another belt, c, drives the conical pulleys E and F, which are connected by the belt d. The belt d can be moved up orrdown the conical pulleys` by means of the forked lever e, attached to a bar, f, below the Hoor B, andoperated by a lever, g, as seen, whereby the motion of the pulley F and its shaft, f, may be regulated. A pulley, f2, on the shaft f1 drives, by means of the belts iand t', the latter of which is crossed respectivclythe loose pulleys h and z" on the shaft K. A sleeve, h, travelling on a squared or grooved part of the shaft'Kfgivcsthe desired motion to the pinion K, when said sleeve is brought in contact with one of the pulleys l,l or z". The pinion K drives,I by Le means of the cog-wheel l, the shaft G on the outer `end of which a pinion gl is attached, which works into a i rack-bar, g2, attached to the under.` side of -thc carriage H. flwo stop-levers, `h2` and h3, at the ends of the clarria'ge, when coming in contact with the reversing lever h", reverse thc'motion of the carriage. The reversing lever is pivoted on a pin Z', and operates by means of a connecting rod, l", the sleeve L, whereby the irret'ion of the shaft G is reversed. The reversing lever h* is held in place by a'spring, m. The motion of the carriage may be stopped altogether by throwing the pinion gl out of gear, which is done by means of aflever, n, which, being connected to the outer bearings of` the shaft G by a connecting rod n', throws this bearing, and `with it the outer end of the shaft, down, when operated uponl for that purpose. The head-blocks I andK are metal bars, provided with teeth at their under side, so that the pinions o and p on the shaft L may operate them. The i shaft L, which passes longitudinally through the carriage, isprovided at its end with a ratchet-wheel, r, operated upon by pawls,r, pivoted to the lever r. The bars I and K slide in and are guided by their respective supports, i and K. When the carriage returns to the starting place, the lever r" is Aelevated by an incline, S, and the pawls 1" operate the ratchet-wheel r, shaft L, pinions o and p, and consequently also the head-bloeks1 and K. An adjustable rest for the lever 1* is formed by two guide-plates t, through which a pin' is passed at "sty the desired height, upon which the lever falls when the carriage is moved forward again ;"the height of the an pin t, will, therefore, designate the thickness of the boards to be cut, which is easily understood. The shaftL y is square for the purpose of always operating the pinion o, which is heldby the head-block support i, the latter sliding longitudinally on the carriage, whereby. a longer or shorter log may be placed upon the saw.
Having thus described my invention, I claim as new, nand desire to secure by Letters Patent- 1. The automatic log settingdevice, consisting of the head-blocksI and K, pinions o and p, shaft L, ratchet` wheel r, pawls 1", lever r, adjustable rest t, and incline S, all constructed substantially as andfor the purpose herein shown and described. v
2. I claim the automatic feeding device, consisting of the carriage H, `reversing lever h4, spring m, andv stop-levers 71,2 and ha, constructed substantially inthe mannerand for the purpose herein shown and described.
JAMES A. HOLFORD.
