SAW-GUARD.

Specicaton of Letters Patent.

Patented Jan. 14,1913.

Application filed May 28, 1910. Serial No. 564,014.

ing the connection between the shoe supporting member and the supporting arm therefor; and Fig. i is a detail view of the connection between t-he shoe and the supporting member therefor. v

Our invention has relation to saw guards, and is` designed to provide a simple, convenient, and efficient form of guard which can be readily attached to various forms of saw tables, either fixed or tilting; and which, when applied to a tilting table will not interfere with the operation of such table. Also to provide a guard which will completely cover the saw and prevent the 'possibility of getting the hands or any part of thebodyain contact therewith, and which will also prevent strips of Wood being thrown by get-ting on to the saw.

A still further object is to provide a shoe of this kind -which is readily adjustable as far forward or backward on the table as. may bedesired; and which can be swung backwardly entirely out of 4the way when not desired for use.

The nature of our invention will behest understood by reference to the accompanying drawings, in which we have shown a preferred embodiment thereof, and which will now be described, it being premised, however, that various changes can be mada` in the details of construction and arrangement of the parts by those skilled in the art without departing from the spirit and scope of our invention as defined in the appended claims.

In thesedrawings, the numeral 2 desig-l nates a saw table, and 3 a saw.

4 is a shoe, which is preferably made of wood, although not necessarily, and which is formed with a vertical, longitudinal slot 4a. This shoe is closed at the top, and tits over the saw in the i'nanner shown in Fins. l and 2, completely covering the saine.

Rigidly secured to one side ofthe shoe is a metal flange or plate 5, which is provided with a central bolt" or pin hole, and with two projecting lugs G.

7 is a huhmenber, which is provided with an eye portion which loosely fits apin or holt 8 insertedtherethrough and into the member 5, and wllich salso provided witha sleeve or socket port-ion 9 to tit the end of a supporting bar or arm 10. The hub member is also provided with a lug T, which extends between the twollugs 6 to limit the pivotal movement ot' the shoe Vwith reference to the hub member. The bar lor arm l0 is .adjustably secured at its upper rear end portion in a hub member 11, which is pivotally supported on the end portion of. an overhanging goose-neck bar or rod 12. This bar or rod is secured at its lower end in a bracket 13, which is rigidly secured to the frame of the machine. is provided with a stop lug 1l, which is arranged to engage the projecting stop lug l1b of a collar 11c secured to the arm 12, when the bar 10 and shoe 4- are swung up wardly and backwardly out of use, into thel position shown in dotted lines in Fig. 1.

The operation of the device will be apparent. The shoe 4 completely covers the saw, but will readily move upwardly to permit the passage thereunder of the piece being sawed, by reason of its pivotal engagement with the pin or bolt 8. The front end of the shoe is undercut. or beveled backwardly, as shown atl db, so that as the piece to be sawed is shoved underneath the same, the front end of the shoe will rst rise slightly. and then the whole shoe will lift by parallel movement, The pivotal connection on thepin or bolt 8 gives suicient flexibility to the shoe, while the provisionof the stop lugs 6 prevents undue movement of the shoe.

vWhen it 'is not desired to use the guard, itmay be thrown upwardly and backwardly into the position shown in dotted lines in Fig. 1, the stop lug 11 engaging the stop lug 11'*V of the collar 11c to hold the shoe in this position. By loosening the set screw which secures the upper end portion ot the member 10 in the hub member 1l. it will'be olivious that the shoe may be adjusted as for forxvardly or hackwardlx of the ta'hlc as may lic desired. This is a feature of sliiccial The hub member 11 t miportance in connection with saws ein-,U0

ploying two mandrels, each carrying a saw, and so arranged that either saw can be brought up into working position.

It will be obviousr that the details of the device may be .changed in many particulars without departing from our invention. Thus, the forni of the supporting bar or arm l2 and the exact means of attaching it to the traine of the saw may be varied to suit the particular foi-1n of saw table to which the device is to be applied. Changes ma)Y also be inadc in the details of the connections between the shoe and its support.

Wvhat we claiin ist-- 1. A saw guard comprising a frame in back of tliesaw, a shoe adapted to lit over the saw and rest on the saw table, a support pivoted to the frame and to the shoe, the pivotal connections being such that the shoe will tiret swing on its connection with the supportwhen the work piece is moved into engagement with the saw and then lswing back lto its normal position with relation to the support while the support will swing on its pivotal connection with the frame, substantiall)T as described.

2. A saw guard comprising a support at the back of the saw, a shoe adapted to tit over the saw and to lie parallel with the upper portion ofthe saw table before the work piece is inserted and after one end of the Work piece has passed beyond the saw, a support pivoted t-o the shoe and the trame, the pivotal connections being such that the shoe Will tirst be swung at an angle when the work piece engages the saw and then swing into a position which is parallel with the saw table after the end of the work piece has passed the center of gravity ot the shoe, substantially :es described.

3. saw guard compi-hing a supporting trame in back of the saw, a Shoe adapted to lit over the exposed portion ot the saw above the table, pivotal connectionsl between the frame and the alice, and a cam on the front endY of the shoe arranged to he engaged bv the work piece to rai. e the shoe, the pivotal connections being such that the front portion of the Shoe will be raised when el'igaged by the work piece and then the heel portion thereof after the work pieiie has passed thel centerl ot gravity il' the shoe, Substai'itially as described.

4. A saw guard comprising a vertically slotted shoe adapted to tit over the exposed portion oil the saw, a member secured there to and carrying a pin or pivot. a hnli niember engaging ead pin onl pivot, said hub member and the lirst named member haring cooperating stop luge, a supporting arm to which the hub member is secured, an overhanging lSupport, a sleeve member loosely mounted thereon and having meanel tor'adjustablv securing thereto the upper end portion of said Supporting arm, and meanS vtor limiting the pivotal movement olf the arm; substantially as described.

In testimony `whereof, we have hereunto set our hands.
