3 Claims. 1

This invention relates to a bench dog which is particularly adaptable for use in connection with a woodworking bench to facilitate operations such as the planing of pieces of wood.

It is an object of the invention to provide a bench dog which can be readily secured to the end of a work bench and which includes an abut-v Another object of the invention is to provide a bench dog of the type described above which is relatively cheap and simple to manufacture and which at the same time is simple in operation and which also is sufficiently sturdy to stand up under continued usage for a considerable length of time.

The above and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same parts throughout the views, and, in which:

Figure 1 is a plan View of the invention show-v ing a portion of a work bench top;

Figure 2 is an end View of the device mounted on a portion of a bench; and

Figure 3 is a section taken approximately on the line 3-3 of Figure 2.

In the drawing there is shown a vertically disposed bracket 4 having a pair of spaced horizontal arms 5. The arms 5 are preferably countersunk in the top of a woodworking bench 6. In Figures 1 and 3 it will be seen that the vertical bracket 4 is spaced slightly from the end of the work bench 6. Positioned between the inner side of the vertically disposed bracket plate 4 and said end of said work bench 6 is an abutment plate 1. Said plate is also seen to be located between the bracket arms 5 in spaced relation to said arms. Screws 8 are adapted to secure the arms 5 to the work bench and the third screw 9 extends through a more or less central portion of the vertical bracket 4 and to the end of the work bench 6. The screw 9 passes through a slot I0 which is formed upwardly from the lower central edge portion of the abutment plate 1.

Pivotally mounted at spaced points on the lower portion of the vertical bracket 4 are levers Il which are swingable on pivot pins I2 which pass through said bracket 4. The upper ends of the levers I I, as viewed in Figure 2, are curved to provide cam devices I3 which bear against the bottom edge of the abutment member 1 to adjustably support said abutment member.

It should be noted that the cam levers Il can be swung together to elevate and/or lower the abutment member 1 in a vertical direction and it should also be seen that the cam levers I I can be selectively operated to tilt the abutment member 1 about the screw 9.

The upper edge of the abutment member 1 is provided with a sharpened corner position I4 so that it will penetrate slightly into the end of the piece of work which is indicated as a board i5.

When the bench dog is not in use it can be lowered so that the upper edge of the abutment member 1 is flush with or below the top surface of the bench 6. Consequently, the abutment member is out of the way when the bench is used for other operations.

The vertical and angular tilting adjustment of the abutment member 1 permits the user to set the abutment member to any desired position depending upon the thickness of the work piece I5 and also depending upon the angularity of the upper surface of the work piece which is being lplaned or sanded or subjected to some other similar operation.

The screw 9 can be tightened to clamp the bracket 4 and abutment member 1 tightly against the end of the work bench when said abutment member 1 has :been adjusted to any one of its desired positions.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.

What I claim is:

1. A bench dog including, an abutment member arranged for attachment to a work bench, said abutment member being vertically movable relative to said bench, and a pair of spaced supports for said abutment member, said supports being shiftable selectively to hold said abutment member in various angular positions relative to the working surface of the bench.

2. A bench dog including, an abutment mem- -ber arranged for attachment to a work bench, said abutment member being vertically movable relative to sai-d bench, and a pair of spaced selectively operable cam devices engaging said abutment member and shiftable to hold said abutment member in various angular positions relative to the working surface of the bench.

3. A bench dog including a bracket adapted for mounting on the end of a workbench, an abutment member shftable vertically relative to said bracket and having a downwardly disposed surface, said bracket being located behind said abutment member to oppose lateral thrust imposed against said abutment member, and a, pair of cam devices supported by said bracket and movable realtive thereto, said cam devices underlying and contacting said downwardly disposed surface of said abutment member, and said cam devices being selectively rnmrable;v
