,- n SAW-GUARD;
SPECIFICATION forming part of Letters Patent No. 302,041, dated `l'uly 15, 1884.
. a Application filed August 2l, 18,83.
To a/Z whom it may concern,.-
Be it known that I, JOSEPH SILL, a citizen of the United States, residing at Picture Rocks, in the county of Lycoming and State of Penn- 5 Sylvania, have invented certain new and useful Improvements in Saw-Guards; and I do hereby declare the-following to be a full, clear, and eXact description of the invention, Such as lwill enable others skilled in the art to which Io it appertains to make and use the same, reference being had to the accompanying drawings, and to lettersor iigures of reference marked thereon, which forni a part of this specification.
4Figure l is a perspective View of a circular sawing machine and saw-guard adjusted over the circular saw by my improved attachment. Fig. 2 is a view of the same parts, showing the Saw-guide adjusted from over the top of the Fig. 3 is a view in detail and section showing the Saw-guard, its head, and the means for adjusting it vertically. Fig. 4 is an en-v larged view of the clamp-box, the eccentric clamping-lever, and the stop applied on the 2 5' upright portion of theswinging arm.
My object is to combine, with a horizontally-swinging arm bearing a circular sawl guard or sheath of segmental form, certain novel devices for adjusting said guard or 3o sheath vertically and horizontally, as will be fully understood from the following description, when taken in connection with the anneXed drawings.
A designates the sawframe, in which is 3 5 suitably mounted an arbor and a circular Saw, B, the upper portion of which latter extends above the top G of the Saw-table, in the usual well-known manner, as Shown in Figs. l and 2." D designates an angular horizontally-ad- 4o justable supporting arm or bracket, which is preferably made of tubular metal, and which has its vertical limb fitted into a clamp-boX,
E, secured rigidly to one side of the sawframe. To this box E, I apply an eccentric,
45 a, having a hand-lever, b, keyed on it for the purpose of gripping or clamping the arm D and holding it rigidly in'either of the posi' tions designated4 in Figs. 1 and 2.
.Directly above the clamp-box E, and fixed 5o to the upright limb of the arm D, is a lug, c, which serves as a stop when this arm D is Renewed June 12, 1884. (No model.)
swung into the position shown in Fig. 2 by impinging against a plate, d, on the main frame.
To the overhanging end of the arm D, I secure a pendant, vF, which iS vertically slotted, as shown in the drawings, and provided with a hollow segmental guard, G, adapted to cover the-upper part of the saw B and protect the Sawyer from flying dust, and also protect him against accident, should the s aw belcome fractured and the pieces be throwni'rom it by centrifugal force. sidesof the guard G will allow the discharge of the sawdust that may get inside.
This guard is guided in its up-and-down movement in the Vertical slot formed in the said pendant, and it is vertically adjusted by means of a worm on a hand wheel shaft, s, vwhich worm engages with the teethi on avertically'guided rack, J, to whichthe said guard G is secured; or I may use, if desired, a wormgear for this purpose.
It will be seen from the above description indicatedin Fig. 1 to that shown in Fig. 2by iirst adjusting itvertical until it iS freed from the saw, then releasing the arnrD from its clamping-eccentric a and swinging the arm around about one-half of a revolution on' its vertical axis until the stop-lug e strikes the plate d. The arm D maybe xed in this position by means of the eccentric a, above described.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y g 1. The combination of the arm adapted to Swing over tlie Saw-table, and having on its outer horizontal end a guardI for a` circular saw, .with a clamp-box iixedto the side of s-aid table for clamping the vertical end of said arm, whereby said guard can be moved on its vertical end or fixed in position, sub- Stantially vas described. 2. vIhe combination, with a saw-table, of Swinging arm having a saw-guard applied to its'overhanging end, and provided with a clamping l.device for the vertical end of the arm, and `a stop-lug, c, substantially in the manner and for the purposes described.
that the guard G is inoved'from the position The orifices g in the i IOO 3. The combination,\with ai'rame having a In testimony whereof I affix my signaturein presence of two witnesses.
JOSEPH SILL.
