WWI/M A T TOE/f5 Y United States Patent 2,752,960 WORK-HOLDING CLAMPS FOR GAUGES Henry L. Poeltl, Milwaukee, Wis. Application May 18, 1954, Serial No. 430,708 Claims. (Cl. 143-157) This invention relates to improvements in cl amp assemblies, and more particularly to a novel clamp assembly adapted for attachment to a bench saw miter gauge.
An object of the invention is to provide a clamp assembly of the type which will hold items of work against a miter gauge while said work is being sawed at an angle.
Another object of the invention is to provide a device of the type which may be quickly and conveniently adjusted to the work to be clamped.
Other and further objects of the invention will appear as the description proceeds, reference being bad to the accompanying drawings, in which:
Fig. l is a plan view of a miter gauge equipped with a clamp assembly embodying the invention.
Fig. 2 is a vertical sectional view taken through the same.
Fig. 3 is a view in elevation showing the device adapted to engage thicker items of work.
Fig. 4 is a plan view showing a modified form of the invention engaging an item of work on a miter gauge.
Fig. 5 is a fragmentary vertical sectional view showing a modified form of socket and nut employed.
Fig. 6 is a view in perspective of one form of clamp assembly.
Fig. 7 illustrates a modified form of clamp plate.
Fig. 8 illustrates one form of nut employed.
Pig. 9 is a view partly in section and partly in elevation of a modified form of clamp assembly.
Fig. 10 is a partial plan view of the same.
Fig. 11 is a partial horizontal sectional view of the same.
Fig. 12 is a side view in elevation of a toggle form of clamp assembly.
Fig. 13 is a fragmentary horizontal sectional view thereof.
Referring more particularly to the first sheet of drawing, the numeral 10 indicates an elongated socketed member or socket element which is provided with horizontally aligned and vertically spaced apertures as at 11, 12, 13 and 14. The socket 10 is adapted to engage over a nut 15 which is provided to replace the usual knob element, not shown, with which a conventional miter gauge is provided. The nut 15 is threaded on the stud bolt 16 in the miter gauge 17. The socket 10 is placed over the nut 15 and in this position may be used as a wrench by inserting the rod element 18 through one pair of apertures as 1.3 and 14. A clamp plate 19 is journaled by means of sleeve 20 on the portion 21 of the rod 18. A wing nut 22 is provided as a stop and is engaged into the thread at 23 of the rod 18. An item of work 24 is placed in contact with the face plate 25 of the miter gauge 17 and by manipulation of the wing nut 22 the clamp plate 19 will secure said work for a cutting operation of the saw 26.
The apertures 11, 12, 13 and 14 are hexagonal, as are the rod elements 18 and 27. In Figs. 4 and 7, a modified form of clamp plate 26 is illustrated, the same being fixed at a right angle on one end of the rod element 27.
In Fig. 9 a modified form of the invention is shown in which a rod 30 has a downwardly bent portion 31 at one end thereof, and is provided with a rack 32 on one of the top sides 33 thereof. The other top surface 34 is smooth. A nut 35 replaces the usual knob, not shown, which provided on the conventional miter gauge 36, and a socket element 37 is placed thereon. The socket 37 has a plurality of apertures at 38, 39, 40 and 41, and the rod is shown held in apertures 40 and 41. A saddle 42 is engaged about the socket 37 and carries the axle 43 which in turn carries the sleeve spacers 44 and 45, the cog segment 46 and the cam 47, provided respectively with the levers 48 and 49. The item of work 50 is placed between the face plate 51 and the clamp plate 52 whereupon lever 48 is pushed down to move rack 32 and rod 30 by means of the segment 46. After the plate 52 is pulled in as tightly against the work 50 as practicable, the lever 49 is forced downwardly whereby the cam 47 will bind against the surface at 34. In Fig. 5 a modified form of nut 28 is employed, the same being short enough to permit free movement of the socket 29. in Figs. 12 and 13 another modification of the invention is shown, in which a toggle mechanism 60 is employed. Movement of the lever 61 downwardly will force finger 62 to bind against the rod 63 to fix the latter against movement through the saddle 64. Movement of'the lever 61 upwardly will free the rod.
Having thus described the invention, it will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claims.
What is claimed and desired to be secured by Letters Patent of the United States, is:
l. A clamp assembly for miter gauges including a vertical socketed member having vertically spaced pairs of opposed apertures, a rod movable through a selected pair, a nut for retaining said socketed member on a miter gauge stud, stop means for said rod for adjusting the length thereof on one side of said socketed member, and a work retaining plate on an end of said rod.
2. A clamp assembly for miter gauges including a vertical socketed member having horizontally opposed apertures, a threaded rod movable freely through said apertures, an elongated nut for retaining said socketed member on a miter gauge stud, threaded means for stopping said rod on one side of said socketed member, and a work retaining plate on an end of said rod.
3. A clamp assembly for miter gauges including a vertical socketed member having vertically spaced pairs of opposed apertures, a rod movable through a selected pair, an elongated nut for retaining said socketed member on a miter gauge, threaded means for stopping said rod on one side of said socketed member, and a work retaining plate pivoted on an end of said rod.
4. A clamp assembly for miter gauges including an elongated vertical socketed member having spaced horizontally opposed apertures, a threaded rod movable freely therethrough, an elongated nut for retaining said socketed member on a miter gauge, means for stopping said rod on one side of said socketed member, anda work retaining plate on an end of said rod fixed at right angles thereto.
5. A clamp assembly for miter gauges including an elongated vertical socketed member having spaced horizontally opposed apertures, a hexagonal rod movable freely therethrough, an elongated nut for retaining said socketed member on a miter gauge stud, means for stopping said rod on one side of said socketed member, and a work retaining plate pivoted on a vertical axis on one end of said rod.
