SAVJ-SETTING DEVICE.

Application filed May 19,

To all whom it may concern:

Be it known that I, ELUAH E. IVAsi-rnUnN, a citizen of the United States, residing at Casper, in the county of Natrona and State of lyoming, have invented new and useful Improvements in Saw-Setting Devices, of which the following is a specification.

The object of my said invention is the provision of a. device of simple construction for quickly and accuratelysetting the teeth of a saw incident to the manual drawing or moving of a saw blade through the device and with but little effort on the part of the operator.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed,

In the accompanying drawings, forming part of this specification Figure l is a view partly in elevation and partly in section showing the device constituting the best practical embodiment of my invention that I have as yet devised.

Figure 2 is a vertical section of the device.

Figure 3 is a horizontal section of the device, taken in the plane indicated by the line 3-3 of Figure l, looking upwardly to show the cooperation of the setting teeth on the rolls.

Figure i a horizontal section taken in thc plane indicated by the line of Fig. l` but looking downwardly.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel device comprises two base blocks l and 2 which are preferably of cast iron, though they may be of any other appropriate material without affecting my invention as claimed. The said blocks l and 2 are arranged side by side and are provided at their lower outer corners with bifurcated feet 3 for the passage of bolts through the medium of which the blocks be adjustably fixed to a bench or other support. The blocks l and 2 are connected together through the medium of headed bolts 4 which extend loosely through the block 2 and engage threaded sockets 5 in the block l as illustrated. At 6 are shims which are interposed between the blocks l and 2 to adapt the device for saw blades of different thicknesses.

Appropriately formed in the blocks 1 and 1922. Serial No. 562,082.

2 and extending to the upper side thereof are sockets 7 of circular form in horizontal section, and are arranged in parallelism. The said sockets 7 are designed to receive stems 8 at the lower ends of setting rolls 9, the said stems 8 being of circular form in horizontal section so as to freely turn in the sockets i', and collars 10 being arranged on the stems S and between the rolls 9 and the upper sides of the blocks l and 2. In accordance with my invention the rolls 9 are arranged with their upper portions spaced apart for the reception of a saw blade, and at their lower ends the rolls are provided as best shown in Figure 3 with meshed teeth l1. These teeth l1 constitute an important feature of my invention inasmuch as they serve incidental to the drawing of a saw blade between the rolls 9, to setting the teeth of the saw. In this connection it will be understood that the teeth 11 are pitched the same as a standard set saw; also, that the teeth are adapted to roll together at the center. For instance, when a saw blade has ten points to the inch, the

teeth ll must be employed to properly set the teeth of the blade, and so on with blades of all kinds. In other words rolls 9 must be employed with teeth ll of a size and character to set the teeth of the particular saw that is to be operated on.

In the practical operation of my novel device. the saw blade is drawn or moved endwise between the rolls, the rolls being rotated by frictional contact with the saw blade, whereupon the cooperating teeth Il of the rolls will quickly and accurately set the teeth on the blade. l

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parte inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as defined in my appended claim.

Having described myinvention, what I claim and desire to secure by Letters-Patent,

A saw setting device comprising base blocks arranged side by side and havingl base blocks and engaging threaded sockets vertical sockets in parallelism, rollsiof steel in the other base block, whereby the blocks 10 or other appropriate hard metal arranged may be adjustably spaced apart to space the above and spaced from the base blocks and peripheries of the rolls and so that shilns 5 having stems removably arranged and freely can be interposed between the base blocks.

rotatable in the said sockets and also hav- In testimony whereof, I affix my siging meshed teeth at their lovver ends, and nature.
