United States Patent SAFETY DEVICE FOR ATTACHMENT TO A SAW Henry D. Schroeder and Edward L. Schroeder, Kanawha, Iowa Application June 12, 1953, Serial No. 361,166
1 Claim. (Cl. 143174) This invention relates to a saw, and more particularly to a safety device for attachment to a saw.
The object of the invention is to provide a safety mechanism for use with a saw whereby wood and other materials can be cut with greater safety.
Another object of the invention is to provide a device which will hold material such as wood being cut safely against a guide member or fence whereby possibility of the operator cutting his fingers will be eliminated.
A further object of the invention is to provide a safety device for a saw which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
Figure 1 is a top plan view, showing the attachment of the present invention mounted on a saw table.
Figure 2 is a sectional view taken on the line 22 of Figure 1.
Figure 3 is a sectional view taken on the line 33 of Figure 4 is a perspective view of the body member.
Referring in detail to the drawings, the numeral designates a table top which may be part of a conventional saw, and the table top 10 is provided with a longitudinally extending slot or cut-out 11, Figure 1. Adjustably mounted on the saw table top 10 is a guide member or fence 12, and extending upwardly from the saw is a cutting member or saw blade 14. The work piece which may be a piece of wood is indicated by the numeral 15, and the safety attachment of the present invention is indicated generally by the numeral 16.
The safety attachment 16 is adapted to be used for guiding the work piece during the cutting thereof so that the possibility of the operator damaging or cutting his fingers will be eliminated. The safety device includes a body member 17, Figure 4, and the body member 17 is slidably or shiftably mounted in the slot 11 so that it can be adjusted to various positions as desired in relation to the work piece. Extending upwardly from the body member 17 and secured thereto is a threaded stem or bolt 18 for a purpose to be later described.
Adjustably connected to the shifting body member 17 is a bar 19, and the bar 19 is provided with a slot 20 for receiving the bolt 18. A nut 21 is arranged in threaded engagement with the upper end of the bolt 18, and a washer 22 is arranged just below the nut 21, there being washers 23 spaced below the washer 22.
An arm 24 is pivotally connected to an end of the bar 2,722,247 Patented Nov. 1, 1955 19, and a coil spring 25 has one end connected to the arm 24, the other end of the coil spring 25 being arranged in engagement with one of the openings 26 in the bar 19. By arranging the spring 25 in engagement with different openings 26, the amount of tension exerted by the spring 25 can be varied as desired. The arm 24 is pivotally connected to the bar 19 by the bolt and nut assembly 27.
Secured to an end of the arm 24 is a bracket 28, and a roller 29 is journalled in the bracket 28, the roller 29 engaging a side of the work piece 15 for coacting with the guide member 12 to insure that the saw blade 14 properly cuts the work as shown in Figure 1.
.From the foregoing it is apparent that a safety attachment has been provided for use with saws. In use, the Work piece 15 is positioned between the spring pressed roller 29 and the guide member 12. Then by moving the work piece 15 along into engagement with the saw 14, the work piece will be held in alignment by the cooperating spring pressed roller 29 and the guide member 12 so that the possibility of the operator getting his fingers cut off will be eliminated. The attachment can be used for cutting various materials such as wood and the operators fingers are nowhere near the saw blade 14. The attachment can be used with a dado cutter and the number or size or the washers 23 can be varied in order to permit the attachment to be adjusted to fit any depth of race or slot 11. Thus, the attachment can be used on any saw. The attachment can be used when ripping, grooving or with a dado cutter or for cutting bevels and the body member 17 fits in the cut-off race 11 of the table saw. If desired two of these attachments can be used, one ahead of the saw blade 14 and one behind the blade, although one will be sufficient in most cases.
We claim:
In combination, a saw table provided with a longitudinally extending slot, a guide member adjustably connected to said saw table and arranged in spaced parallel relation with respect to said slot, a saw extending upwardly from said saw table and spaced from said guide member, a safety device attached to said table and including an oblong body member slidably mounted in said slot,
a vertically disposed securing element extending upwardly from said body member intermediate its ends, a bar provided with a longitudinally extending slot for receiving said securing element, an arm pivotally connected to an end of said bar, a bracket secured to said arm, a roller journaled in said bracket for engaging a workpiece, a coil spring having one end connected to said bar and its other end connected to said arm, said body member having a transverse cut-out in its upper surface snugly and slidably receiving therein said bar, washers circumposed on said securing element and interposed between said body member and said bar.
