SAIV-SEITING MACHINE.
Specification of Letters Patent.
Patented Nov. 11, 1913.
Application filed March 17, 1913. Serial No, 754,826.
To all whom it may concern:
Be it known that I, Fnnnnnrc GALPIN, a citizen of the United States, residing near 'Villiamsfield, in the county of Knox. and State of Illinois, have invented a new and useful Saw-Setting Machine, of which the following is a specification.
My invention. relates to devices for setting the teeth of saws, and the primary object is to provide novel means for successfully and with great facility accomplishing that end. And while the invention relates primarily to use of the peculiarly shaped co-acting wheels (presently described) as a means for setting saw-teeth, it will be manifest that by turning either shaft (as 12) to actuate its wheel (as 19) said wheel will impart movement in the contrary direction to the other wheel (as 26) and thereby to its shaft, and inasmuch as the couples thereof are flexible relatively to each other, also as later herein described, a flexible gear is provided.
It is an object to provide means the relative positions of some of the elements of which may be readily altered to effect setting of saw-teeth widely difierent in con struction (or constructive details) and size, as regards length, breadth, and thickness.
Another object is to provide co-acting tooth-setting wheels having peculiar and novel structural characteristics.
Also it is an object to so construct each tooth of each wheel that when certain elements are dispensed with and the manner of operation changed, whereby the saw is guided and moved between said wheels, it will be fed forwardly by said teeth.
It is to be understood from that which precedes, and as well from the description soon to follow, that the broad idea of my invention contemplates not only means which move longitudinally of and on a held or stationary saw, but comprehends also certain changes in said means whereby the saw may be moved through a portion of said means while the latter is not moving as a body, or traveling, but is rotating as in the other manner of operation. Concisely stated, the device has two modes of operation, either the saw being moved through the for carrying my invention into effect, Figure 1 is a side (or end) elevation; Fig. 2,. a similar view, but partly in section and some of the elements not shown, while some are in changed relative positions from that shown in Fig. 1; Fig. 3, a rear elevation; and Fig.
4, an enlarged fragmental detail.
3 Referring to the drawings by numerals and uniformly employing the same one thereof to designate the same part in each of the views, 2 indicates abase on which are secured a pair of standards 3,4, and a pair of table-supporting legs 5, 5, on which is supported a table 6. The standards are prothese are mounted the gudgeons 7, 8 of a swinging frame 9 provided with a guideway 10. 11 is a crosshead sliding in said way and apertured for the passage of a shaft 12 on which is keyed a pinion 13 which meshes with the teeth of a rack 14 seated on an offset projection 15 on said frame 9.
16 is a spacing collar.
17 is a crank-arm on the the handle thereof.
Axially fixed on the forward end of the shaft 12is an oval gear wheel 19, the top of each tooth of which is longitudinally arcuate', as shown best in Fig. 2-a contour with which I have achieved the best results. .Each tooth top is provided with a longitudinally arranged groove 37 for a purpose presently described.
Mounted in hearings in the lower portions ,of the standards 3 and 4 are the gudgeons 21, 22 of a swinging frame 20 provided with a guideway 24 in which a crosshead 23 recip rocates. This crosshead also is transversely apertured for the reception of a shaft 25 for which it is a bearing, and said shaft is either integral with or fixed to an oval gear-wheel 26 in mesh and preferably identical in construction with the wheel 19 and which.
therefore, requires herein no further descrippnii n 13, and 18 '70 vided each with an upper bearing,and in i of-which arefixed to and on the 8 and 22, respectively.
tion. For the purposes of this specification the wheels 19 and 26 may be herein termed tooth-setting wheels. 7 r
Mounted in brackets 27 onthe standard3 is a shaft 28 to which is secured a worm or 'serewj29 the threads of which engage the teeth of upper and lower rack-arms or swinging segments, 30, 31, respectively, both gudgeons 32 is a milled or knurled knob on the projecting end of the worm-shaft 28 and by rotations or part rotations of which the arms 30, 31 and thereby the upper and lower pairs of gudgeons'may be moved to swing the upper and lower. frames and simultaneously tilt or incline the saw-setting wheels 7 at such angles or relationship to each other as may be predetermined, all of which is dependent upon the nature and characteristics of the saw to be operated upon.
'33- designates a saw-clamp or yoke'supportedabove the table 6 onthe terminals of a pair of wing-screws 34, by which it may be raised bodilyor by adjustments of either of which it may be tilted or inclined as desired. j
3 6' designates a clamping-screw for look "ing the saw within the clamp.
'The'operation'i The saw having been secured in the clamp 33 said clamp may by means of either or both screws 34:, 35 be worm 29; It will be noted that the longitudinally considered top of each tooth of each of'said wheels is arcuate and that the corresponding spaces between the pairs of I V mined and made, the operator will actuate thecrank-arm 17 and thereby the pinion 13 teeth are likewise in contour, whereby when 1 the wheels aretllted on their longitudinal axes that tooth which is resting in a space between two teeth in the companion wheel willToclr-thereiri,and that inasmuch as the teeth taper from a considerable width at "theirebut ts to a relatively narrow point at their'tips, it is an easy matter to bring a tooth and its corresponding space into such relationship that they will conform in size to saw teeth differing'vastly in their widths. The proper adjustments having been deterand shaft 12 to rotate the wheel 19 and i V therebythe wheel 26. 'As the teeth of these alternately engage spaces in the other, alternate saw-teeth will'be forced upwardly or downwardly, as the case may be, to properly set them, for the setting wheels will advance in a path longitudinally over and -in contact with said saw-teeth and with reference to the rack 14 by reason of the pinion 13 meshing with the latter and moving thereon, whereby the crossheads will move and operate in an evident manner.
Should it be desired to move the saw through the teeth of the setting wheels while they are rotating but otherwise stationary, the rack 14 is laid aside, whereupon rotations of the pinion 13 will impart like movement to the wheel 19 and thereby to the 'wheel 26. The saw-teeth tips or extremities will engage the shoulders providing the grooves 37 and be fed along thereb and by the frictional contact of the tops 0 the setting-teeth.
While I am aware that saw-setting teeth have heretofore been devised, none to my knowledge has been provided with an oval tooth-setting wheel or wheels such as I have shown and described, and it may be here stated that I consider the main feature or gist of my invention, or that part thereof which relates to the saw setting means per so, as residing therein.
Having thus described the nature of the invention and having illustrated and described preferred structural means for carrying it into effect, I claim as new and desire to secure by Letters Patent the following, to-wit:
1. In a saw-setting machine, a toothed oval wheel tapering substantially to a point, each tooth thereof provided with a longitudinal channel in its top, and means cooperating therewith whereby saw-teeth may be set. r
2. In a saw-setting machine, a pair of toothed oval wheels in mesh, means for rotating them, and means for advancing both while they are so rotating. 7
3. In a saw-setting machine, a pair of toothed oval wheels in mesh, a worm, and means interposed between said wheels and worm whereby said wheels may be simultaneously tilted on their longitudinal axes.
L. A device of the character described comprising a pair of toothed oval wheels in mesh, a saw-clamp, and means for raising, lowering, or tilting said clamp with reference to said wheels,
5. In a device of the character described, a pair of toothed oval wheels adapted each to tilt longitudinally and one of them to impart rotary movement to the other,
and means for imparting such movements thereto.
6. Ina saw-setting machine, a pair of toothed oval wheels in mesh, and means for rotating them, each tooth of at least one of said wheels being provided with a longitudinally arranged groove.
7. In a saw-setting machine, a pair of toothed oval wheels in mesh, means for rotating them means for simultaneously tiltsignature at Galesburg, Knox county, Ill., ing them longitudinally, swinging frames this 7th day of March, 1913. provided each with a Way, and crossheads adapted each to travel in one of saidways FREDERIC L 5 whereby said Wheels are caused to travel Witnesses:
