NTTED STATES JOHN A. GEEK, OF HADLYME, CONNECTICUT.
INIPROVEM ENT IN SAWING-MACHINES.
Specification forming part of Letters Patent No. 52,039, dated January 16, 1866; antedated January 10, 1866.
Toall whom it may concern:
Be it known that I, JOHN A. GEER, ofHadlyme, in the county of New London and State of Connecticut, have invented a new and Improved Sawing-Machine; and I do hereby declare that the following is a 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, Sheet No. l, is a vertical section of my invention, taken iu the line w x, Fig. 5; Figs. 2, 3, and 4, detached views of parts pertaining to .the same; Fig. 5, Sheet No. 2, a vertical section of the same, taken in the line y y, Fig. 1; Fig. 6, a vertical section of the same, taken in the line z e, Fig. 1.
Similar letters of reference indicate like parts.
This invention relates to a new and improved sawing-machine, designed for sawing curved work, such as fellies for wheels, and other articles which are in the form of portions of circles.
The object of the invention is to obtain a simple device for the purpose specified, and one which will operate with but little friction and will admit ofbeing manipulated or worked by an attendant with the greatest facility.
A represents a framing, on which a horizontal platform or bed, B, is secured, and C is a driving-shaft, placed in the lower part of the framing, and having a crank-wheel, D, on its inner end, to which a pitmau, E, is attached, the latter operating a saw sash or gate, F, which works on guides a, attached to a suitable support, G. To this sawsash there are attached two pairs of saws, H H H H', the saws of each pair being at such a distance apart as to saw the stuttl of the required width, as shown clearly in Fig. 1.
I l represent two shafts, which are fitted in permanent bearings, and have each a corrugated roller, J, on them, said rollers being par-k allel with each other and having their Lipper surfaces projecting a tritle above the surface of the bed B. The shafts I I have toothed wheels b on their inner ends, into which a wheel, c, gears, the latter being on a shaft, JX, which has a ratchet, K, upon it. The wheel c has two wheels, d d, gearing into it at opposite sides, and these wheels d d have their axes in the outer ends of bars e e, the inner ends of which are fitted on the shaft J". (See Fig. 2.) The axes of the wheels d d have barsfftitted on them, through the outer ends of which the journals of shafts L L pass, said shafts having wheels g g on them, which gear into the wheels d d.
The shafts L L have their bearings in an adjustable frame, L", which may be adjusted higher or lower by means of set-screws h. The shafts L L also have corrugated rollers IVI on them, which are directly over the rollers J. These rollers M J constitute the feed, and they are operated by means of a pawl, N, which engages with the ratchet K, and it receives its motion from a rock-shaft, O, which is operated from the saw-sash F by means of an arm, P, connected to the saw-sash by au elastic bar, Q.
The arrangement of the gear-wheels b b c d d g g admits of the shafts L L rising or falling to conform to the variation of the thickness of the stuit' or wood which is between the rollers M J, the bearings of the shafts L having springs R resting or bearing upon them to admit ot' this vertical movement or yielding of said shaft.
The stuitl or wood from which the fellies or curved articles are sawed is clamped to' an arm or bar, S, by means ot a dog` T. This arm or bar S is titted in a swivel-socket, U, attached to a slide, V, which is placed on abar, W, and secured thereon at any desired point by means of a set-screw, h'. The bar S may be moved in the socket U, and secured therein at any desired point by a set-screw, t'.
In consequence of the loa-r S working or turning from the socket U as a center, it will be seen that the wood may be sawed in the form of a curve, which will be a portion of a circle, of which the socket U is the center, and by shifting the socket U on its bar W the curve may he varied-that is to say, sawed in the 'form of a portion of a larger or smaller circle,
as required.
Both pairs of saws are provided with a precisely similar means for feeding the stuff or wood to them but the saws H' H are shown as provided with feed-rollers J', similar to J of the other saws. The upper free rollers, M',
however, which correspond to the rollers M ot' the other pair of saws, H, are simply titted in an adjustable frame, LX X, corresponding to the frame LX of the saws H, and have springs cx resting 0n their bearings bx; but no gearing;` is employed to give the rollers M apositir'e motion. This latter plan may be used in certain cases; but the one previously described as used in connection With the saws H H is preferable.
Having thus described myinventioml claim as new and desire to secure by Letters Patentl. The combination ofthe adjustable pivoted
