Letters Patent No. 110,765, dated January 3, 1871.

IMPROVEMENT IN CARPENTERS SHQOTlNG-BOARDS.

The Schedule referred to in these Letters Patent and making part of the same.

I, JOSEPH Jouns, of the city of Newark, in the county of Essex and State of New Jersey, have iuvented certain Improvements in the Oarpenters Shooting-Board secured to me by Letters. Patent, No. 52,719, issued February 20, 1866, of which improvements the following is a specification.

The first improvement relates to the bed-piece upon which the piece of wood lies to be planed;

The second relates to the stop and to its adjustment; and

The third to an addition to 'the stop.

Figure lis a plan of the bed-piece, showing the improvements in bot-h bed-piece and stop;

Figure 2 is an end view of the same;

Figure 3 is the additional attachment to the stop;

Figure 4 is a top view', and

Figure 5 is an end view of the same.

A is the bed-piece, which, from the end'g/ to the stop, is a separate piece from the main frame 5 B is the main frame;

C is the base-board 5 and D, the stop.

In providing for the elevation of the bed-piece A, it is essential that its upper edge, next to the face of the plane, should be the center of motion, remaining close to the face of the plane, while the lower edge recedes therefrom, asthe bed-piece is turned up to a required angle. To this end two rods, X, each a segment of a circle, Whose center is at z on the upper edge-line of the bed-piece, are att-ached' to and form part of the bed-piece A, and more in guides in the main frame B.

Upon the edge of the baseeboard C is a hinged screw-bolt, V; and to the back edge of the bed-piece there is attached a slotted bar, W.

The hinged bolt V goes through the slot in the bar WV, and the bar is held in position by the thumb-nut az, securing the bed-piece A at any required angle of inclination.

The frame B has, from the end of the bed-piece A, at z, its upper face level with the bed-piece, when that bed-piece lies flat on the frame, upon which level face the stop D is secured.

t and u (the latter shown by dotted lines in fig. Il) show two slots in the level face, placed at rig-ht angles to each other.

A pin, d', passes through the slot u and the footpiece q of the stop'D, and a bolt, with a thumb-screw or nut, s, alsol passes through the foot-piece q and through a slot, t, in the frame, by'which the stop is made easily adjustable to any required angle, and is heldsecurely in place ont-he frame.

As an additional support to long stuff when having `a bevel plane'd on its end, the frame, fig. 3, is made conveniently attachable to and detachable from the stop D.

In the outer bar of that frame is a semicircular slot, which is a segment of a circle, whose-center is :i on the main frame.

A projecting support, k, held by athumb-screw, is by those means adjustable, as may be required, to any desired inclination. v

Thus, having described my improvements,

\Vhat I claim, an'd desire to-secure by Letters Pateut, is

The bed-plate B and adjustable table A, in combination with'the stop D, all the parts b eing constructed, arranged, and operating in the manner and for the purpose as shown and described.

JOSEPH JONES.
