UNITED STATES PATENT OFFICE.
JOHN MURLEY, OF MORRIS, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO HERMAN O. GIFFORD, OF SAME PLACE.
ADJUSTABLE SAFEGUARD FOR CIRCULAR SAWS.
SPECIFICATION forming part of Letters Patent No. 227,287, dated May 4, 1880.
Application filed March 6, 1880.
To all whom it may concern v Be it known that 1, JOHN MURLEY, of Morris, in the county of Grundy and State of Illinois, have invented certain new and useful Improvements in Adjustable Safeguards for Circular Saws; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference beinghad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a side elevation of my safeguard for circular saws, and Fig. 2 is a transverse sectional view of the same.
This invention relates to an adjustable safeguard for circular saws.
The improvement consists in the construction and arrangement of parts, as fully set forth in the following description, and particularly pointed out in the claim.
. 1n thedrawings, A designates thesaw-guard, which consists of a metal or wooden plate formed with a recess, a, and with two mortised arms, B, which arms fit upon a standard, 0, so that the guard can be "ertically adjusted. The saw is designated byletter D, and is covered in part by the guard, as illustrated.
The guard is held in place upon the standard by means of a set-screw, E, which is employed to tighten up the arms upon the stand ard, and to this end the set screw passes through plates F, which are secured to the arms on opposite sides of the same, so that the walls of the slots in the arms may be drawn against the standard. The said standard has a slot,
G, through which the set-screw passes, the slot (No model.)
admitting of the vertical adjustment of the set-screw and guard. The standard has a base, H, which works in a guide, I, and which is held in place therein by a set-screw, K, which passes through a slot, L, in the bottom of the guide. By this arrangement the guard can be set in posit-ion for protecting saws of various diameters, since the standard which supports the guard can be readily adjusted in place in the guide I. I
The guide is set upon the saw-table, and the board which is being sawed is fed toward the stan dard which separates th e cut, thus preven ting the board from pinching the saw.
The vertical adjustment of the guard is for the purpose of regulating its position with reference to various sizes of boards, and it will prevent pieces flying away from the saw and injuring the operator.
hat I claim, and desire to secure by Letters Patent, is
In a saw-guard, the combination of the vertical standard 0, slotted at G and made hori zontally adjustable in the guide I L, with the guard A, recessed at a and provided with the mortised arms B, plates F, and set-screw E, the several parts being so constructed and arranged that the edge of the vertical standard 0 will enter the kerf as the board is fed forward and prevent the saw from being pinched, as set forth.
In testimony that I claim the above 1 have hereunto subscribed my name in the presence of two witnesses.
JOHN MURLEY.
