W'LLIAM DUN BAR, OF LARRABEE, PENNSYLVANIA, ASSIGNOR OF ON EHALF TO JUDSON J. NEVMAN, OF BUFFALO, NEV YORK.
EDGER.
SPECIFICATION forming part of Letters Patent No. 311,422, dated January 27, 1885.
Application tiled July 17, 1884.
' To aZZ whom t may concern:
Be it known that I, WILLIAM DUNBAR, a citizen of the United States, residing at Larrabee, in the county of McKean and State ot` Pennsylvania, have invented certain new and useful Improvements in Lumber-Trimmers, of which the following is a specification, reference being had therein to the accompanying drawings.
1o This invention is for the purpose of trimming both ends of hemlock and other lumber at the same moment and cutting the sticks in lengths running from four to twenty-four feet, and when there are bad places in the larger r 5 sticks to cut them out by raising intermediate saws by levers at the same moment that both ends are cut. The device is also for cutting ties, slab-bolts, Src., cutting ties of sixteen feet in halves, and trimming the ends at the same 2o time.
The main object of this invention is to out off the two ends of lumber, leaving the sticks in exact lengths or sizes, and simultaneously with this cutting out, when required, by intermediate saws the bad spots or parts of the lumber; and the invention consists of the combination and arrangement of the four saws for this purpose, and also in an automatic combined series of stops for the extreme end of the lumber to rest against, and at the same time indicate the length ofthe stick to be cut, all as fully hereinafter explained.
In the drawings, Figure l is a top plan of the entire machine, only the usual table being removed; Fig. 2, a front side elevation; Fig. 3, an elevation of one end, showing the operation of levers, Src., which throw up the combined stop and indicators.
A A indicate portions of the rectangular to frame work which supports the operating parts, and A in Fig. 2 the upper part or table.
B is the prin cipal operating sa w-shaft, which runs the entire length of the machine, and
with its ends journaled in boxes in the ends of the frame, as shown in Fig. 2. In Fig. lit is not shown, as it runs directly under other parts. On this shaft B, for a short distance, is cut a screw-thread at each end, and on these 5o threads moves a frame, b, (one at each end,)
'carrying a saw, a a. The upper part of the (No model.)
saw-frame slides on a shaft, c, and the lower part on a guidesrod, c', (see Fig. 2,) the same at both ends of the machine. These saws a a receive motion from pulleys d d, (see Fig. 1,) and the screw-thread on shaft B is right-hand at one end and left-hand at the other, and when desired to move these saws farther apart to-cut the ends of longer sticks the operator turns a hand-wheel, e, on a shalt, f, which op- 6o erates a beveled gein-wheel, g, at its other end, which meshes into a small beveled gear, l1., on the end of the main saw-shaft B, thus throwing these end saws farther apart, or drawlng them together to their limit.
At the opposite end from the operators frame O is the frame O, both being parts of the main frame, but narrower, as shown .in Fig. l. This frame Ois provided with a'serles of levers, Zi Z, at the bottom, which are plvoted in the lower front cross-piece ot' the frame, as shown at k, Fig. 3. At the opposite end each lever is pivoted to an upright stick, Z, the top coming level with the table through loose clamps. These levers stand a foot apart, and the upper ends are painted to ind1cate 1n feet the distance or length apart of the main saws. This is done as follows: On the bottom of the saw-frame b, at this end, is a wheel, a. (Shown in Figs. 2 and 3.) As the saws are thrown go apart as before explained this wheel n strikes each lever t' in succession until the .one is struck that throws up the stick Z, indicating the number of feet required. ln Fig. 2 1t 1s shown on the rst lever Z, and that has thrown g5 up the stick, called a combined stop and indicator,7 against which the stick or st1cks to be sawed are pushed. In Fig. 3 the last lever, i, is the one on which wheel a rests, and it has thrown up the last indicator and stop Z. Every foot the operator moves the saws a a counts two feet-one at each end; therefore these stops are painted 18, 20, 22, and 24 feet, the saw always being opposite the indicator and kept there until all the lumber of that length is sawed.
Zhen bad spots in the sticks or lumber are observed by the operator, he steps on the footlevers 19p,which are so fulcrumed as to throw up intermediate saw-frames and saws c a, 103 either or both. One is used when short sticks are to be cut, in connection with one end saw a. The saws are shown up in Figs. l and 2.
When a bad place is cut out, the leversv p are released, and the saw and frame drop belowl the table by their own weight.
rIhe exact construction or operation of these saws and frames I do not claim, and therefore any more particular description is omitted. Only their combination in connection with these extension end saws is new. It isl four feet from saw c to saw a at the operators end, four feet to next intermediate saw, a, and eight feet to extreme end saw a, and the two end saws have eight feet extension. Ihus both ends of lumber can be cut simultaneously in lengths of from four feet to extreme length of the machine. The usual chains, ss, and their Wheels u u are employed for carrying the lumber on the table to and from the saws. w w are the usual lumber-rests next saws c a.
rIhe great novelty of this machine is that it unites in one simple device severa-l important points, such as cutting both ends of lumb'erat once and into exact lengths required; also outting out bad places therein atsametime,which saves greatly in labor,.in Weight, and consequently in freight in shipping such lumber, thiswork being done on the ground instead of after being shipped.
I am aware that it is not new to use two-or more saws adapted to be adjusted on an arbor.
/Vhat I claim is- 1. In a lumber-trimmer, the combination and arrangement of the end saws,a a,on screwshaft B, the intermediate raising and lowering saWs,a, a, thesaw-frame b, provided with the Wheel n, and the pivoted 'levers i fi i, with the stops and indicators Z Z Z pivoted thereto, all substantially as and for the purpose specified.
2. In a lumber-trimming device, the end C of the main machine, provided with the pivoted levers z' t' ,equidistant apart, having the upright stops and indicators Z Z, pivoted thereto and operated by the movement of the savv- 'fraine b, having the wheel n at the bottom coming in contact with said levers, all substantially as and for the purpose specified.
In testimony whereof` I affix'my signature in presence of two witnesses.
WILLIAM DUNBAR.
