CHARLES P. CASE, or TROY, PENNSYLVANIA.
Letters Patent No. 92,266, dated July 6, 186?l IMPROVEMENT IN SAW-FILING MACHINE.
The Schedule referred lto in these Letters Patent and making part ofthe same.
To all whom it may concern.-
\ Be it known that I, CHARLES P. OASE, of Troy, iu
the county of Bradfbrd, and State of Pennsylvania, .have invented a new and valuable Improvement in Saw-Filing Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and' operation of the same, reference being had to the annexed drawings, making a part of ythis specification, and to the letters and iigures of reference marked thereon.
Figure l of the drawings is af front view of my inventiou.
Figure 2 is a sectional View through line y y ofig'. 1.
F'gnre 3 is atop view, showing machine applied to circular saw'.
Figure 4 is a view of file-holder and slide.
My invention relates to devices for Bling mill-saws; and
It consists mainly in constructing and arranging means whereby the teeth of either Straight or circular saws may be led with perfect accuracy, and with great despatch, either by a belt or gear from machinery, or by hand-power.
The letter A of they drawings represents a frame constructed of an L-form, as shown on fig. l, upon the front or longitudinal part of whichI attach the hollow bedplate B, and cross-heads c, in the manner represented.
Resting and arranged to slide upon these cross-heads c is the frame I). fIt is adjusted and attached to said cross-heads by means of sliding boxes, which clasp said cross-heads, and are united to said frame by means of screws, as shown at cl in fig. l.
The letter E represents a ratchet-wheelconnected with the shaft c, which said shaft has a screw` cut on its rear end, that works in a thread cnt in the head of a standard at the point g. This crank-pinion and shaft furnish means by which the frame D is moved back and forth upon the cross-heads c.. It is drawn forward by means ofthe crank, and is moved rearward usually by means hereinafter mentioned.
The letter h represents a lever, attached atits front or lower end to the Shaft lc bymeans of a sleeve-head, while its rear or top end rests loosely upon the shaft o, described hereafter.
The letter t represents a spring attached to the front bar of frame D,fand is slotted to receive and hold the lever It, as shown.
The lever k is pivotedto an arm extending from the front side oi' frame D. It is notched near its top, as shown in iig. 3, to adapt it for work in the side of the slot in spring i, in which it rests. llhe office of these notches, in combination with the spring 1', lever h, and
Iset-screw I, next mentioned, is to raise, lower, and regulate the pawls n, as hereinafter set forth.
.the pitman.
not attached so firmly in the slots y ,as to prevent this Y Letter l is a thumb-screw, arranged as shown.
The letters n represent pawls afixed to the side of lever hfand they are united with the springt' by means of chains or cords, as shown. rIhese pawls actnate the ratchet-wheel E, and in conjunction with the devices heretofore and hereafter described, serve to move the frame D rearward, and feed the files to the saw. By using two pawls I am enabled to move the pinion half a notch at ea'ch revolution ofthe machinery, and I may move it still more slowly by the use of additional pawls.
The letter H represents a band-wheel, to which I sometimes apply a crank for hand use.
The letter o represents a shaft, to which the'wheel H is connected. This shaft rests upon the frame D in suitable journals, and serves as the working-shaft Y ofthe machine.
The letter o is an arm extending from 'the front side of shaft H, inside its wheel, and letter s is an arm attachedto the rear end of said shaft at the rear of the frame D. .y
rlfhe arm r has a catch or pin near its upper end, which, at eachrevolution of shaft H, serves to raise the top end of lever Tt, and thereby operate the pawls above described.
The letter K represents a pitman, attached at one end to arm s, and at. the other to the filing-frame P, in the manner shown. I attach to the rear side of. frame D a sliding frame, which moves longitudinally, thereon, and -which I call the filing-frame. It is attached to frame D by grooves and iianches, lor by any other suitable means, my object heilig to givefit easy play, and arrange it for lubrication in the best possible manner. -It is marked P on the drawings. y
The letters o represent arms attached to the rear side -of frame P, and are made adjustable thereon by meansof slots and set-screws, as shown in fig. 4.
In the arms c, and in the manner represented on fig.
4 and 3, I attach two files by means of suitable set-v screws. They are placed in an angular position with each other, and thereby adapted to work-upon-both the top and bottom of a saw-tooth at the same time.
The plate by which the frame I? is united to frame D has slotted openings for screws, as shown at y on fig. 3. rlhe object of this device is to give the fileframe a lateral movement, and thereby to relieve the files from the saw-tooth at each return movement of It must. be observed that thescrews are lateral movement of the file-holder.
, rlhe above and foregoing devices are intended more particularly for filing circular saws, although they are susceptible of use for many other purposes.
To file an upright saw, I make use of the devices i shown on the right-hand .portion of tig. 2, and which are partially represented on fig. 1. They consist mainly in a hinged frame, adjustable at any desired angle, and removable at will, in which an upright saw may be s ccurely held and adjusted vertically, or sidewise, and thereby brought to the tiles above mentioned in any desirable manner.
The letter R represents the hinged frame attached to the rear end of frame A.
lhe let-ters S are plates attached to frame A, and extending upward by the sides of frame R, and having out in them respectively slots corresponding to segments of eireles. I
The letters a are thumb-nuts, arranged to work in the slots last above mentioned, and secure the frame I in the position desired.
`The letters e' represent a series of rollers, operated by the bevelled pinion-gear shown on fig. 2.
The saw to be filed is placed, and is held between these rollers c' in the manner shown on said fig. 2, and it is moved forward at will by means of the pins al', that rest against its back, and are operated bv means of the screw and crankJ markedT.
, The saw is moved up or down by means of' the crank and bevelled gear operating the rollers e.
One great advantage secured by the mode'of adjustment'provided by the circular slots and thumb-nuts in the plates S is, the operator can adapt the position ot' the saw to the shape in which he desires to form the tooth, and thereby adapt it to the kind of timber in which he desires to use sueh'saw.
By means of the screw anderank 'l, the pins d', thumb-screw l, (which operates to lift the pawls from their ratchet,) and the other devices mentioned for holding an upright saw firmly in place, I am enabled to keep Such saw properly gauged by the tiling-process alone,and thereby secure another important advantage.
fie-2te The L-portiou of frame A is dovetailed into the main frame, and thereby made removable at will.
This device is essential, for the reason that,lin-iliug circular saws the L-portion should be entirelyde tached. l
Between the lever K and the front side of' the frame, and resting upon the arm in which said lever is pivoted, l affix a block" of solid India rubber, that serves as a spring to aid the movements of said lever. I sometimes also place similar blocks of India rubber'between the rollers e' and the frame thereof, or upon the jonrnals of said rollers, to aid in the movements of. the4 thumb-nuts a', pins cZ, crank and screw T, and bevelled gear, as described, constructed and arranged to operate substantially as and for the purposes specilied. 4. The above-described machine for filing san s, both on the upper and lower side of a tooth, at one operation. i
In testimony that I `claim the above, I have hereunto subscribed my name, in the presence of two wit,-
nesses.
