CIRCULAR-SAW DREESSER.

SPECIFICATIQN forming para of Letters Patent No. 619,533, dated February 14, 189e.

i Application filed June 1, 1898. Serial No. 682,236. (No model.)

To all whom, it may concern:

Beit known that I, HARLEY L. BEE, a citizen of the United States, residing at Blandville, in the county of Doddridge and State of West Virginia, have invented a new and useful Circular-Saw Dresser, of which the following is a specification.

My invention relates to circular-saw-dressing-machines, and has for its object to provide a simple, inexpensive, and eliicient device adapted for rounding or truing circular saws to avoid the inconvenience common in practice of .dressing the teeth of a circular saw by manually holding an emery-stone or file in position to grind the long teeth and produce uniformity in the length of the teeth.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a saw-dresser constructed in accordance with my invention. Fig. 2 is a front view, partly broken away, of the same.

Similar numerals of reference indicate corresponding parts both the gures of the drawings.

The device embodying my invention includes a clamp l, constructed for engagement with a saw-frame and having a clampscrew 2, whereby it may be securely locked in position, and upon this clamp is mounted a frame bar or support 3 for adjustment laterally of the saw-frame, and hence transversely to the plane of a saw to be dressed. Said frame-bar carries a guide 4, upon which is mounted a slide 5, having parallel arms 6 arranged upon opposite sides of the guide, with the contiguous faces of the arms and guide constructed to interlock, as by the slide-arms having tongues 7 to it in grooves S in the guide. In the construction illustrated the guide is secured to the supportingarm 3 by means of bolts 9 and movement of the slide upon the guide may be accomplished by means of a feed-screw 10, which is swiveled in an ear l1 on the slide and is threaded in a standard 12 on the guide, said feed-screw terminating at its rear end in a hand-wheel13.

The body portion or head of the slide is provided at its front end with parallel jaws 121, between which are pivotally mounted clamp members 15, provided at their inner sides with seats 16 for an emery-block, and the adj ustment of the clamp members toward each other may be accomplished by means of setscrews 17, threaded in suitable openings in the jaws 14..

As above indicated, the frame-bar or supporting-bar 3 is adjustable transversely of the sawfran1e upon the clamp 1, said bar being guided upon the clamp by means of the interlocking faces thereof, the frame-bar in the construction illustrated having grooves 18 to receive ribs 19 on the clamp, and in order to lock the frame-bar at the desired adjustment I employ a clamp-bolt 20, extending upwardly from the clamp 1 through a slot 21 in the bar and iitted with a thumb-nut 22.

When it is desired to dress a circular saw, the apparatus embodying my invention is secured to the saw-frame contiguous to the sawblade by engaging the clamp 1 therewith, after which the frame-bar 3 should be adjusted to arrange the emery-stone-holding jaws in the plane of the saw-blade and should be securely clamped in this position. Then after adjusting the emery-stone the operator by means of the feed-screw may advance the slide to bringthe abrading object into contact with the extended or long teeth of the saw, and subsequently may further advance the slide, as required, to gradually reduce the length of the projecting teeth and produce uniformity thereof. It will be seen that this operation may be accomplished without danger to the operator, in that his hands are removed from the saw during the adjustment of the emery-block or other material which may be used for the purpose of grinding the teeth.

Should the teeth on the log side of the saw require dressing to a greater extent than those on the board side, one of the setscrews by which the stone-holding jaws are adjusted may be loosened and the other tightened to dispose the stone at an angle, this adjustment being possible by reason of the pivotal mounting of the jaws 15.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit IOO or sacrificing any of the advantages of this invention.

Having described my invention, what I claim isl. A saw-dressing machine having pivotal spaced jaws mounted upon a support for angular adjustment with relation thereto and provided with seats for an abrading object, and means for angularly adjusting the jaws to vary the angular position of the abrading object with relation to the plane of a sawblade, substantially as specified.

2. A saw-dressin g machine having supporting devices, a slide mounted upon the supporting devices, pivotal spaced jaws for holding an abrading object, means for angularly adj usting the jaws, and feeding devices for advancing the slide, substantially as specified.

3. A saw-dressin g machine having supporting devices, a slide mounted upon the supporting devices and having a head provided with fixed jaws, pivotal jaws mounted between the fixed jaws and provided in their facing surfaces with seats for an emery-stone, set-screws threaded in the iixed jaws and arranged in operative relation with the pivotal jaws, and means for adj usting the slide, substantially as specified.

4. `A saw-dressing machine having supporting devices, a slide mounted upon the support- 3o ing devices, pivotal jaws having seats for an emery-stone, means for adjusting said pivotal jaws to vary the position of an emerystone laterally and an gularly with relation to a saw-blade, and a feed-screw for adjusting the position of the slide, substantially as specified.

5. A machine for dressing circular saws, having a clamp for engagement with the frame of a sawing-machine, a supporting-bar mounted upon said clamp for adjustment in a direction transverse to the plane of a saw, a clamping device for securing the supporting-frame at the desired adjustment, a guide carried by the supporting-bar, a slide mounted upon said guide for adjustment parallel with the plane of the saw, means for operating the slide upon its guide, an'demery-stoneengaging devices carried by the slide, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

HARLEY L. BEE.
