Description
YLFEI'ERS, PNOTILUTNOGRAPHER, WASHINGTON. D C.
have invented certain `shaped, so as. to correspondwith a @sind giedre LUCIUS J. COBB, .OF
CHICAGO, ILLINOIS.
Letters Patent No. 103,568, (lated .May 3l, 1870.
VIMPROVEMENT IN RESAWING-MACHINE. A
The Schedule referred to in. these Letters Patent and making part of the same.
To all 'whom it'anay concern: Be it known that I, LUcIUs J. COBB, of the city of Chicago, in the countyiof Cook and State of Illinois, p new and ,useful Improvements in Machines for Resawing Planks, Src.; a'ndI do hereby declare that the following is a full, clear, andA exact description thereof, reference being had to the 'accompanying drawings making apart of this specification, in Which-- Figure I represents a side elevation. Figure 2, a top or plan viewl Figure 3, a modification of the mode of belting the machine; and" L Figure a modification of the' gearing by which the feed-roIlers are'operated.
The nature of myinvention consistsjn an improved mode 0foperating the feed-rollers, and in tbe several combinations hereinafter set forth.
To enable others skilled in theart to make and use. my invention, I will proceed to describe the improved machine.
. Y .lhe frame A 1s made of Wood or iron, as may be desired, and, when made of wood, is seven feet long and four feet wide for a forty-inch saw. When made of iron, the size can be reduced, and it will vary according to the size of the saw to be used.
The saw B i`s made very thin, and is attached to its shaft in any of the usual modes, and is placed in the middle of the machine, between the bars k k.
The shaft is supported in sliding journal-boxes, which are fitted to the inside of the frame c, and are held in said frame by having the ends project beyond the sides thereof with a flange, or by being made V- projection fitting them inside ofthe framea.
At each end of these frames or boxes a, I insert lon" screws, land c, the inner ends of which press against the journal-boxes, and, by means of these screws, the saw can be moved forward or backward, and also accurately adjusted to the line of cutting.
iVhen the machine is rst setup, the screws c will be run in nearly their entire length7 and the screws b drawn out, as shown, so that, as the saw wears away, by unscrewing c and screwing b, the saw-teeth are kept `in the same position relative to the pressure-bars or jaws D. i
Near the outer edge of the saw I insert or attach pressure-blocks or guides, d, to the bars 7c, which guides are held in place by the set-screws e, and, as they be.- come worn, they are advanced so as 'to be kent in contact with the sides of the saw. The attachment will be simplified byl making these guides of hard wood,
. with a screw-thread made upon them, and thereby save the intervention of a set-screw. By the `use of these nruides, I am able to use a ,very thin saw, of a` lar e i diameter, which is desirable in saving timber an` in lesawing wide boards, and by the use oi' these guides withthe thin spreader or guide E, the back lash or scraping of the rear teeth of the saw upon the boards is prevented.
The bars 7.; are placed above the saw-shaft, and arc supported in front bythe cross-bar U', and at the rear by a tail-block, or-by other suitable means.
At the front end of the machine two iron crossbars U are located, and their inner faces are grooved, as shown at figs; I and 3.
In this groov at the'top, I first place a center bar, j, and on each si e of this center bar a separate frame, T 'Il'. 0n each of these frames l l" are placed the feedrollers and the devices for operating them.. fllhestI rollers are about seven inc-hes in diameter and eighteen inches in length, and are provided with suitable bearings at the base in thefiames 'I T", andai: the top lu the beam or bars M.
The bars M are supported and held by the posts F.
I adjust the space between the two sets of rollers by vmeans of a post or bar, H, which is bolted to the main frame A, and provided., at its upper end, with a screw, i, which passes thgough it, and has its nut in 'anIl'nplright or post, G, thelower end of which is secured to the'outer edge of the frame T.
From the upper end of this post G Athere is a ver tical plate, G', passing to the supportingost F.
At the outer end of this plate there 1s a slot, h,
through which the screw g passes into the top of the post G, by means of which the feed-rollers can be adusted with reference to the frames T, and, when properly adjusted, the screw g is turned down and the rollers are held as placed, and the rollers are adjusted with reference to the space between the two sets by means of the screws i ofthe posts H; and on one side I place a'spring, R, or a weighted lever, so that the rollers will yield without breaking when required. l
The feed-rollers are operated by means of the wheels P, on their upper ends, connecting with the worms or bevel gear-wheels O' Aon the shaft N. r
Ihe shaft N is supported by the arms O which project from the bar M, and :ne provided with suitable bearing-boxes.
'Ihis shaft also supports the loose arm or bar L.
rIhe bars L, at their front ends, are branched, so as to furnish the supports of the shaft X, as shown,and, being pivotally connected with the shafts N, the bearings oi' the shaft X are self-adjusting, so that there can be no unusual friction or binding when the two sets of feed-rollers are moved toward or from each other, or one or both of them placed in an incline@ position.
I from it by additional -belts or bands.
The collars of the wheels W rest against the bearings, so'thatthe gearing, with the wheels V, is not disturbed by any movement ofthe feed..
"llhe wheels lV are made to revolve with the shaft by means of the usual slot and key, the key'being so Ilttedthat the shaft can slide through the wheels.
Power is applied, by means of a belt, to the drive- -wheel Y, and communicated from the pulleys J to the t and K. I design, in'use, to use saws as large as sixty Ainches (five feet) in some of my machines, and, .in that case, it will be necessary to use additional guides, d, above those shown, to keep the saw steady, and with suchv guides I can use saws of that diameter and three thirty-secondths of an inch in thickness, and saving about one-half of the power required to do the same work with the machinery now in use. The jaws D are in common use.
The operation will 'be obvious from the description.
Having thas fully described my machine,
What I claim as' new, and desire to secure by Letters Paten-t, is-
1. The combination ofthe wheels P, located at the top of the feed-rollers, with theavorms or wheels O',
shafts N and X, wheels V and W, and movable frames T and T', substantially as set forth.
2. The arms L, when supported on the shaft N, and provided with bearings for the shaft X, substantially as specified.
,3. The combination of the movable frames T and T with the posts H and screws i, for adjusting the space between the feedrollers, so as to produce boards ofV equal thickness, substantially as described.
' 4. The plate or bar G', provided with the slot it, n combination with the standards G, post F, and crossbar M, for adjusting the pitch of the feed-rollers, sub s tantially as spe'eied.
