HENRY J. MILLER, OF SHEBOYGAN, WlSCONSlN.

SAW-SET.

Specification of Letters Patent.

' Patented July 3, 1906.

Application filed September 20,1905. Serial No. 279,319.

To all whom, it may concern:

Be it known that I, HENRY J. MILLER, a citizen of the United States, residing at Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented a new and useful Saw-Set, of which the following is a specification.

This invention relates to saw-sets, and has for an object to provide a device of the class embodying new and improved features of convenience, durability, utility, and efficiency.

A further object of the invention is to provide a device for setting circular saws, in the operation of which the teeth of the saw are automatically advanced for setting.

A further object of the invention is to provide a saw-set embodying improved means of adjustment to operate in connection with saws of different diameters and gages.

With these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a top plan view of the improved automatic saw-set. Fig. 2 is a longitudinal sectional view of the set. Fig. 3 is a top plan view of the star setting-anvil.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

In its preferred embodiment the improved saw-set forming the subject-matter of this application comprises a base 10, provided with the upstanding flanges 11, formed along the longitudinal edges, and an upstanding lug 12 at the end and between the flanges. Opposite the lug 12 the base is continued to .any approved length and provided with any approved number of openings 13, by means of which a circular saw, as 14, is pivoted to the base, as by the bolt 15, upon which the hub of the saw is mounted.

Upon the base and between the flanges 11 is slidably mounted the setting-head 16, movable in a direction radially to the saw, as by the screw 17, journaled in the lug 12 and engaging screw-threads in the head and operated in any approved manner, as by the hand-wheel 18. The settinghead has a shoulder 19, upon which is mounted a setting-anvil of any approved form, but preferably of star form, as 20, secured by the screw 21. Above the anvil the settinghead has an outstanding nose 22, through which is inserted a screw 23, arranged to bear upon and maintain the saw 14 in operative position upon the anvil.

The setting-head is bifurcated to form the upstanding ears 24, between which are pivoted at the setting member 26, proportioned to contact at an incline with a tooth upon the anvil. To force the setting member into setting contact with the tooth, a lever 27 is pivoted between the cars at 28 and provided with an eccentric cam-surface 29 in contact with the setting member, and which forces the setting member upon the tooth against the tension of the spring 30.

Upon the bolt 15 is pivoted an arm-section 31, continued by the section 32, longitudinally adjustable by means of the slot 33 and bolt 34. WVithin the slot 33 is also secured the swivel member 35 with asimilar member 36, carried by the lever 27, and the two swivel members connected by the curved link 37.

Upon the outer end of the outer arm-section 32 is hinged the pawl 38, carrying at its end opposite the hinge the downwardly-extending finger 39, held in engagement with the teeth of the saw by the spring 40, attached to a stud 41, carried by the arm-sea tion 31.

A saw is mounted upon the bolt 15 in one of the openings 13, the selection of the opening depending upon the diameter of the saw. By means of the hand-wheel 18 and the screw 17 the setting-head is then moved to such position that the teeth of the saw are upon the anvil 20. A depression of the lever 27 will then force the setting member 26 down upon and to curve the tooth upon the anvil 20 and will also draw the arm in the direction indicated by the arrow A, the finger 39 passing over the teeth without turning the saw by reason of the disposition of the pawl 38 and the spring 40. WV hen, however, after the tooth has been set the lever is raised, the finger will engage with the teeth and turn the saw in the direction indicated by arrow B the distance occupied by two teeth, thus advancing automatically to the setting-head the base for engaging the center of, and supporting a circular saw, an arm pivoted on said means, a pawl carried thereby and adapted to engage the teeth of the saw, setting mechanism, and means operated there-' by for actuating the pawl.

2. A saw-set comprising a base, means upon the base for engaging the center of, and supporting, a circular saw, a longitudinally-adjustable arm pivoted upon said means, a spring-controlled pawl connected to the arm for engaging the teeth of a saw, setting mechanism adjustably mounted on the base, a lever for actuating the setting mechanism, and a rod pivoted to the lever and adjustably connected to the arm for regulating the stroke of the pawl.

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