Description
i NITE ATES B. SMITH, OFVMILWAUKEE, W'ISGONSIN.
MACHINE non Momrsme sAsrLsTILEs; n
`Specification of Letters Patent No. 11,253, dated July 11, 1854.
To all w/lwme may concern.' l Be it known that I, J. B. SMITH, of Mllwaukee, in the county of Milwaukee and `State of Wisconsin, have invented a new and `useful Improvement 1n Machines `for Mor tisingSash-Stiles; 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, forming part` of this specification, in which parts.
The nature of my invention consists in a novel arrangement of mechanism, so as to constitute a mortising machine, capable of mortising both ends of sash stiles of any desiredlength, and of clearing out the mortises simultaneous with their completion, without the necessity of reversing the ends of thel stiles, `or` tightening and slackening the driving belt. This arrangement avoids the necessity of laying out the stuff, and enables me to effect a considerable saving of l labor and time.
tising chisels attached to the sliding stocks,
C, @,which slide up and down in the guides,
.D, D', which are attached to the central cross-pieces ofthe frames, A, and G. These chisels are set a' suiiicient distance apart for a sash stile, el, to lie between them; and B, with its stock C, and the guide, D, are
. made capable of moving so as to be adjusted nearer to, or farther from, D', when 1t 1s desired to mortise stiles of agreater or less length. Each of these chisels is worked by `a crank movement, a, b, c, said crank movements being connected to the pulleys, E, E, and through the peculiarly arranged band, H, and pulleys, F', F2, are set in motion,
two of said pulleys, those lettered E, E, be-
ing arranged in a movable or sliding frame, Gr, which is moved backward and forward by the screw, I. By thus arranging two of the pulleys in a movable frame, and connecting it to the movable chisel `and stock,
I am enabled to adjust it and the chisel at the same time by the screw, I, andto set the chisel so as to be capable of mortising a long or short stile. i
N, N', are two stationary j horizontal chisels, attached, to the stationary guides, D, D', of the chisels, B, B'. Stationary `chisels are employed for cutting horizontally as fast as the power chisels cut vertically, so that the mortise may be completed before the `stile "is removed from the machine, said stationarychisels, when the mortise is completed, being at the bottom of the same, and consequently, as` the movable bed is lowered by the treadle, serveto raise and discharge all thechipsout of the mortise. The stile, d, rests on a movable carriage, J, which is moved back and forth laterally by `the lever, e. This carriage rests on, and is fastened by means of the pins, 7i., z, to the movable bed, K, which is raised or lowered by means of the treadles and levers, L, L', L2, L3, which are operated by the foot; said pins, Iz., z, playing` freely` in the slots, z', in the bed, K, as the carriage, J, is moved back and forth laterally. p
M, is a hinged lever for holding the stile in place, and preventing its rising, while being mortised, as shown in the drawing. The driving belt, H, is passed round the pulleys, E, E, F', F 2, in the manner shown in the drawing, and by thus arranging it, the cutter B,can be adjusted, and the distance between it, and-B', diminished or increased without tightening or loosening the belt, as may be evident.
J, J, are adjustable stops forvregulating the length of themortise; and c, ic, are similar4 stops for regulating its dept-h.
rIhe operation of this machine is as followszThe piece to be mortised is placed on the carriage, asshown in red color, and the hinge lever, M, is brought over on to it, and `held with one hand to prevent it from being raised by the chisel in mortising. The movable bed,\K, is raised, (by applying the foot to the treadle, L,) to the position shown in thedrawing; and the stilemoved by applying the hand to the lever, c, to a position to. be operated upon by the cutters;` The power is now applied to the machine, and
the chisels B, B', caused to move up and down, and that, B, to gradually cut the mortise, in one end of the stile, of the required l depth, and the stationary chisel, N, as the stile is fed laterally toward it, to cut horizontally and loosen the part of the wood desired to be removed, as fast as the chisel, B, cuts vertically. As soon as the mortise is out ottn the required length and depth, the bed, K, is lowered by the treadle, L2, and lever, L3. This operation'lowers the stile, and as the chisel, N, occupies a position at the bottom of the mortise when completed, it is caused, when the bed is lowered, to retain the chips, and consequently to effect their discharge from the mortise. One end of the stile being mortised and completed, the bed is raised, and the opposite end of the stile is moved by means of the lever, M, in contact with the chisels, B, and N, and operated upon by said chisels in the same manner as the opposite end was operated upon by the chisels, B, N. ln order to move the chisels farther apart, or nearer together, so as to mortise different lengths of stuff, the screw, I, must be turned in the directions indicated by the arrows, l and 2, and if in the direction of the arrow, l, the distance between the chisels will be diminished; and owing to the arrangement ofthe driving belt, the part, t, of the same will be decreased in length, while the parts, will be increased in length; and thus the belt is always kept suiciently taut to drive the machine, andthe necessity of changing it avoided.
What claim as my invention, and desire to secure by Letters Patent, is-
l. The arrangement of the parts substantially as herein described, so as to constitute a 'machine capable of mortising both ends of sash stiles of any desired length, andl cleaning out the mortises simultaneous with their completion, without the necessity of reversing the ends of the stiles, or tightening or slackening` the driving belt, substantially as herein described. Y
2. I likewise claim the combination and arrangement of the vertical` power chisels, B, B', and the stationary chisels, N, N', with the movable bed, K, and sliding carriage, M, or their equivalents independent of the arrangement of the driving belt when used for lnortising sash stiles of only one length, and cleaning out the mortises, substantially as described.
