hue/Wm f TATES IMPROVEMENT IN SAWlNG-MACHINES.
Specification forming part of Letters Patent No. 123,223, dated January 30, 1872.
To whom it may concern Be it known that I, GEORGE S. Brace, of Drayton Plains, in the county of Oakland and State of Michigan, have invented a new and useful Improvement in Sawing-Machines; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which my invention is shown and set forth in perspective.
The nature of this invention relates to an improvement in the construction of a combined sawing-machine and saw-buck, by the use of which the labor of wood-sawin g is materially lessened. The invention consists in the peculiar construction and arrangement of the various parts, as more fully hereinafter set forth.
In the accompanying drawing, A represents a suitable frame, which supports the operating parts of the device, and to the prolongation of which the saw-horse B is secured, one of the legs, 6, of the said horse forming a brace to steady the upright portion of the frame. D is the main driving-shaft, running in suitable boxes, a, secured to the frame, as shown. Motion is communicated from this driving-shaft to the counter-shaft E by means of the geared wheel I), and pinion c, or their known mechanical equivalents. F is the balance-wheel, se-
cured to the counter-shaft E, and one of its arms is provided with a wrist-pin, to which is attached, in the usual way, the pitman G. H is a pair of parallel curved rods, the opposite ends of which terminate upon the same plane, and are finished as slides I, between which work the cross-heads I, which are connected together by the curved connecting-rod J. The saw K is secured between these cross-heads, as shown. The curved rods H, which form the slides, are pivoted at their inner ends by means of journals working in the boxes d. The opposite or outer ends of these rods are secured to a cord, e, which passes up over a pulley at the top of the standard L, and thence downward to the treadle M, to which it is secured for the purpose of elevating the outer end of the saw, when desired. N is a knee, pivoted to the frame, and its under side is provided with one or more spurs, to hold the stick of wood from turning while being operated upon.
The object of curving the rods H and J is to allow the saw to pass entirely through the wood, while they form a suitable frame within which and by which the saw is operated.
VVh-at I claim as my invention, and desire to secure by Letters Patent, is-
A combined sawing-machine and saw-buck, wherein the frame A, buck B, shafts D, E, balance-wheel F, pitman G, slides I connected together by the curved rods H, cross-heads I secured together by the curved rod J, saw K, cord 6, pulley and standard M, and knee N, all constructed and arranged to operate substantially as set forth.
