.wel tibia SAMUEL HUNTER, OF ANDREW COUNTY, MISSOURI.
Letters Patent No. 83,856, dated November 10, 1868.
The Schedule refelrrdd to in these Letters Patent and making part of the name Be it known tha-tI, SAMUEL HUNTER, of Andrew county, in the State of Missouri, have invented a new and useful Improvement in Sawing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and letters of reference mrlled there on, making a part of' this specilication, in w 1c Figure 1 is a front elevation Figure 2 is a plan view;
Figure 3 is an elevation of the side on which is the saw-gearing; and
Figure 4: is a rear elevation.
To enable those skilled in the art to make and use my invention, I now proceed to describe its construction and operation.
` Similar letters in the drawings refer to like parts.
This invention relates to a portable machine for saw ing logs, at the places where they are felled, crosswise into bolts, blocks, cord-wood, &c., or, by adjusting the sawin a vertical position, lengthwise, into boards', plank, or the like; and it consists in adjusting a peculiar and novel horse-power to the frame-work supporting the machinery; also in adapting a peculiar and novel belttightener to the same; and also in adapting the gearing, by means of which the saw is moved, to an adjustable gate, to which said saw is attached, as will hereinafter more fully appear.
In the drawings, A represents a substantial tiamework, mounted upon a stout carriage, B, by means of which latter the frame, with itsunachinery of various kinds, is transported from place to place. Upon the front part ofthe carriage B are two semicircular plates, a a', projecting forward, the lower plate a being supported at its centre upon the front cross-bar of the carriage, and attached at each end to the lower ends of the forward uprights 'h I1 of the flame-work, the upper plate a resting upon the lower plate, edge to edge, and pivoted at its extremities to the uprights I, so as to be capable of being raised upon its said pivots. Semicrcular notches, c,are cut at suitable points along the upper edge of the plate a, and similar notches, c', at corresponding points along the lower edge of the plate a', each pair of' notches c and c' forming, when the upper plate is shut down upon the mwen-circular holes, in either of which may be'placd the shaft d of the horse-power, the inner end of said shaft being secured in a pivoted uprght,.so that the shaft may be rotated around this upright as a centre, andransferred from one hole of the plate a a to another at pleasure, accordingto the direction it may be found convenient to give it, in forests and similar places, Where the maf chinery is more especially designed to be put in operation..
The shaft d is connected, by bevel-gearing, with a vertical shaft, e, held upright by a suitable bracket on slides upon said shaft, being supported at one=side by the spur-gear l', and at the other side upon the ends of the arms l, projecting beneath the spur-gear l' from the end of the gate m, which also sustains the said spurgear l. The gearing k" and l' .imparts the motion delived by belt from the main sheaves', by means of a crank, m', to a connecting-rod, m", joined at its opposite extremity to the saw u. The gate mis supported upon two vert-ical screws, mf m", placed in the near end or' the vflame-work, by means of which screws, which receive simultaneous rotation, in the same direction, through the agency of the connecting spur-gear o, the gate is moved up or down as'occasion may require, as
in cutting through alog, or withdrawing from the saine.
The upper end of the screws is provided with sheaves r r, roundeither or both of which the belt may be passed to assist in the operation.
On the top of the frame-work isa horizontal guideway, s, stretching crosswise half way, more or less, of the flame. Within the lguide-way slides a bar, s', provided at its outer end with a handle, s, and notched for a suitable distance upon its upper side, and pivoted at its inner end to or near the centre of a bar, t, the
forward extremity' of which is pivoted to the front up.-l
per cross-beam of the frame-work A, and to the rear extremity of which-is attached an upright roller, t. To the guide-way is pivoted a pawl, s", which is arranged to catch in the notches in the upper side .of the bar s', where a lever, n, pivoted to a side beam of the frame, nearly under the said bar s', is brought down so as to bring its eccentric-head, u', underthe bar s', and so elevate it against the pawl s. Whcl the bar s' is tiras elevated, it cannot be slid in or out, and is thus ni a condition efficiently to aid the roller t' inthe discharge of its function of a belt-tightener.
Having thus described my invention, What I claim as new, and desire to secure by Leiters Patent, is
The plates a, a', the lower rigid, the upper pivoted, provided with the orilices c c', adapted to varying the direction ofthe drivingshaft,'substantiallyasdescribed.
