Definitions

  • My invention relates to saws, and my ob-' ject is to produce a saw adapted for general use, and particularly to crosscut-sawing, for which at the present time hand-operated saws are almost universally employed.
  • my saw comprises an endless chain provided with teeth and suitably mounted and guided, which is driven continuously in a single plane of motion.
  • This chain of teeth is adapted to be pivoted at one end in a suitable support, so that it can be swung bodily in an are against and through a tree, log, slab, or other structure.
  • Figure 1 is a side elevation.
  • Fig. 3 is an enlarged sectional elevation at one end of the frame.
  • Fig. 4 is a plan
  • Fig. 5 is a detail end view of a link of the chain with a tooth in place, the saw-frame being shown in cross-section/
  • Fig. 6 is an elevation showing a portable saw on horizontal work.
  • Fig. 7 is a plan view of the same.
  • Fig. 8 is an elevation of a mill-saw on vertical work.
  • brackets 2 which may be formed either in one piece or of separate parallel plates, both constructions being illustrated in the drawings.
  • a guide-wheel 4 having a deeplygrooved periphery
  • bracket 3 is adjustably mounted a su bstantially similar wheel
  • Fig. 2 is a top I plan of frame and guide-wheels with s'aw re-,
  • each link 9 in the tapering slot of each link 9 is set a saw-tooth 14, hav- 7S ing a tapered shank 15, which tightly fits the slot and shoulders 16, which bear upon the edge of the link adjacent to the slot.
  • An opening 17 is made at the base of each projection 13, partly in order to insure the accurate seat- 30 ing of'the shoulders on each tooth and partly to facilitate the extraction of any tooth by permitting the insertion of a suitable tool below its shank.
  • This frame, chain, and teeth constitute an endless saw, adapted to run continuously and to form a single saw-cut in the plane of its motion, and it is adapted to kinds and styles of sawing for which neither circular saws, band-saws, nor mechanically-operated reciprocating saws can be used, and for which hand-operated saws are always employed, the two-handled crosscut-saw being a familiar example.
  • FIGs. 6 and 7 the stump of the tree shown may represent a redwood stump as ordinarily left after felling and contains enough material to make a good bolt, but would ordinarily be left standing, as not warranting the expenditure of time and labor required to saw it through by hand.
  • My saw is in this case shown as mounted upon a portable skid 21 and furnished With driving power, such as asteam-engine, gas-engine, or motor of any kind.
  • the engine 22 is here shown as geared to the shaft of the guidewheel 4, which is extended into suitable bearings 23 on'the skid.
  • the continuously-moving saw is swung on its pivots and otherwise controlled by an operator at the handle 8 and cross-cuts the stump or tree quickly and easily and low down, thus utilizing material ordinarily wasted.
  • Fig. 8 the saw is supposed to be set up in a mill and to be employed in cross-cutting logs for bolts.
  • the frame is shown as hung in a-suitable floor-bracket 24 above the blocks which support the log, and is driven by a belt 25 from the mill-shafting.
  • the saw is thus perfectly free above the log and can be brought down upon and through it under control of the operator with greatfacility and despatch, the log resting upon floor-blocks.
  • a chain-saw structure comprising a chain-saw, a bar-frame therefor lying wholly within the cutting plane of the saw, having saw-supporting wheels at its ends and pivoted at one end on the axle of one of said wheels, and a handle at the outer or free end extending beyond the cutting range of the saw.
  • a chain-saw structure comprising a chainsaw, a bar-frame therefor lying wholly within the cutting plane of the saw, having sawsupporting wheels at its ends and pivoted at one end on the vertical axle of one of said wheels, and a handle at the outer or free end extending beyond the cutting range of the saw.
