JAS. B. LOWRY, OF NORTH EAST 'lONVNSHEIP, COUNTY, PENNSYLVANIA, AND PHILANDER' EGGLESTON, OF MAYVILLE, NEYV YORK.
SAWMILL.
Specification of Letters Patent No. 2,120, dated June 11-, 1841.
To all whom it may concern:
- Be it known. that we, JAMES B. Lower, of the township of North East, Erie county, and State of Pennsylvania, and PHILANDER EGGLESTON, of Mayville, Chautauqua county, and State New York, have invented a new and useful Improvement in Sawmills. for Sawing Timber; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification.
Figure 1 is a perspective view of the saw mill., Fig. 2 is a section showing the lower vibrating beam, chains, feeding rods, &c. Fig. 3 is a section showing one of the lower slides and stirrups; Fig; 4 one of: the upper slides and stirrups.
Similar letters refer to corresponding parts.
The frame A may be the same as that used for similar purposes, and. may be varied in the construction to. suit circumstances. There must be twobeams Z), b, above the saws and two below them; said I beams must be about twenty inches wide and ten inches thick and secured to. posts 0, c, by means of tenons. made to, fit into mortises made in the posts so that each pair of beams will have about 15 inches space between each beam (this however will be governed by the width of the saw) and they must be a suitable distance apart to sustain the guides (Z in their proper position (to. be described hereafter). This: will be governed by the length. of the saws, the lower beams b 6 must be placed with the upper edge level and parallel with the joists. About t feet from the center of the beams transversely there are metallic guides. cl inserted and secured tov the inside of the beams by arms Y, Y, passing over the edges of the beams in notches made for the purpose, in the upper edges of the beams b b to receive them and in blocks Z, attached to the lower edges of the beams b, b, when the beams are not sufiiciently wide to. support the guides (Z without the blocks ZI Said guides (Z must be sufficiently long to hold the stirrups to their places when the saws are in motion, their length being determined by the length of the crank and they must be placed para lel t each oth r and perpea dlCLLltll tothe floor so that the stirrups E Wlll work freely. Said guides (Z may be from two to. 4 inches wide and about one serve to, raise or depress them, and serve also, to tighten the saws as will hereafter more fully be described. There are two posts, 6 Fig. 2 being one of them, attached to the lower pair of beams 7) b projecting downward about four feet from the lower edge of said beams 6 or sufficiently far to allow the lower working beam H to work freely (as will be hereafter more fully described). Said working beams H HF must be made of such length that when. supported at their center and resting on pivots or gudgeons, the ends of said beams will receive the chains j to be hereafter described. To. do, which the most outward surface of the segments at K described as being fixed onthe ends of the working beams. H H will be nearly perpendicularly under the guide (Z. The working beams H may be constructed of wood or metal and must be made of a size suited to the material of which they are constructed and. in reference to the power to. be applied.
On the ends of the arms of each beam H described as radiating exactly from the center of the working beams H are fixed the segments K, which segments .ought to. be about 8 feet long, or such length. as will correspond with the stroke of the saws, said segments, must be smooth on their surface and sufliciently thick to. support the chains.
The lower working beam H may be placed between two posts 6 Fig. 2, formed in the same manner as the posts 6 above described, and corresponding with them in everyrespect except their length and position. Both working beams have journals or pivots Z at the center of suiiicient strength to sustain them firmly against the pressure arising from tightening the saws and also from the operation of sawing. nals or pivots work in boxes F (metal or wood) inserted in the posts 6 e in the upper pair of beams 12, Z) and in the posts 6 c of the lower pair of beams (7) b Said boxes must be made adjustable by means of keys and slides so arranged as to keep the said boxes from moving in a lateral direction. 7
There are four flat chains 7' j which connect the saws with the ends of the working beams H. Said chains are fastened to the beams H by attaching one end of the chains to each end of the working beams at the upper end of the segment K on the upper beam H by bolts or staples at m, m. The other end of said chains are fastened to the stirrups s by passing a link between two loops of the stirrups S at the upper end in S and by passing a bolt or pin through the loops and link. Said chains j ought to be as wide as the saws and made strong with as short links as possible. The chains j, 7' are attached to the lower working beam H at the lower end of the segment at n, n, in like manner to thosedescribed above.
The slides E and stirrups s, s before alluded to for guiding and supporting or connecting the saws are as follows, viz. The upper slides E, E are constructed in part of a piece of fiat metal in such form that their length will be about eight inches and their breadth about twelve inches or f of sufficient width to extend from the guides of one beam to those on the opposite beam, with a groove in the middle of each edge to admit the guides (Z or to allow the slides. to move freely up and down the guides, the grooves are made wider, or reduced in; width as occasion may require, one side being made movable, and is governed by,
to keep the saws from deviating from a right line. The iron strap or stirrup s which composes another section of this connection of the saws and chain, is made out of a bar of iron about five eighths of an inch square and about five feet long, the ends of which are then brought and welded together to an oblong form, the sides being straight and parallel to each other, about seven inches apart, the ends forming a loop, the ends are brought over the slide until nearly together to admit the saws between them, leaving a loop of about two inches below the slide to admit the iron pin which unites the slides and chain together. This form of bending produces two loops at the other end of the slide, through whicha bolt passes to connect it With the chain Said jourabove described. The iron bars straps or stirrups, above described may be secured to the slides by nuts and screws.
The lower slide E Fig. 3 differs from those above described by being formed to run on two guides in front, and one in the rear of each stirrup, the distance between the two grooves should be about eight or nine inches forming nearly a semi-circle at 00.
The feeding or propelling the carriage is performed by rods W WV in Fig. 2 made of iron or wood or both, and attached to the lower working beam on each side of the fulcrum and about one third of the distance from said fulcrum toward the segments, said rods are attached (by being split to pass on each side of the beam) with a bolt passing through eyes formed in the end of each portion of the rod, and into the said beam. Or they may be made with a joint or hinge fastened to the top of said beam H, and secured by bolts or staples. Said rods "W l/V pass upward through the floor, and also through mortises in knees 79 such as are commonly used to Work the hands on the rag wheel with holes in the upper end to regulate the feed. There is also a lever T projecting downward from the lever working beam at the center, about four feet long and six inches square said lever is secured to said beam by a tenon and braced by rods of iron passing from the segment on the end of said beam at n, a to near the end of said leverT. To the lower end of said lever is attached a horizontal pitman 10 which communicates with the balance crank L which may be propelled by a belt passing from a drum wheel or may be propelled by any power used to propel other machinery.
hen one saw is to be used the place of the other may be supplied by an iron rod.
The advantages derived from this improvement consists in lessening the friction, dispensing with the weight of the saw gate and applying all the power to cutting lumber. The weight being thus taken from the crank, it will wear much longer as well as also the boxes in which it runs. lVhere two saws are used, it will be seen that one is ascending and the other is descending which serves to regulate the motion, consequently better adapted to being propelled by strap or cogs, put in motion by horse or any other power, than any other kind of mill driven by crank motion, also the saws being. balanced, the velocity may be increased to any extent desired without injury to the parts, or danger arising from fire or any other inconvenience, other than what would arise from any rotary motion, and from the increased motion it is susceptible of, in this arrangement, the feed may be light and consequently the saws may 2,120 be thinner than in the ordinary way, and hat we claim as our invention and the work be done better, more even and which we desire to secure by Letters Patent smooth. The power being applied to cutis ting in place of raising the saw gate is a The combination of the slide E and stirsaving of from one half to three fourths rup S by which the chain and saw a are of the power so used. This arrangement, united as herein set forth.
combination and improvement possesses all JAS B LOVRY the advanta es of a rotar motion with a T perpendioulzi r stroke and 11 strained saws PHILANDER EGGLESTOL' leaving nothing in the way to obstruct the Witnesses:
free and open passage of the mill excepting TM. P. ELLIo'r,
the saws and feeding Works. SILAS LAMSON.
