JOHN E. CRYER, 0E PEORIA, ILLINOIS.

\ J' DINER S BENCH.

Specification of Letters Patent No. 24,102, dated May 24, 1859.

To all whom 'it may concern.'

Be it known that I, JOHN E. CRYER, of Peoria, in the county of Peoria and State of Illinois, have invented a new andluseful Improvement in Joiners Benches for Jointing and Squaring Boards and other Lumber; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and made to form a part of this specification.

My invention relates lst to a device for adjusting and securing a movable jaw by means of which the lumber to be worked may be held rigidly in its proper place; 2d, to an adjustable rest or gage, by means of which the lumber to be worked may be jointed and squared to an even given width as hereinafter specified and represented.

In reference to the accompanying drawings, Figure l, is a perspective view showing the bench with all its parts arranged for operation. F ig; 2, is an end view showing specially the device for operating the movable jaw. Fig. 3, is asectional front view, showing the adjustable gage; the dej vice by means the same may be adjusted, the

graduated scale and index.

(A) represents a frame work similar to a joiners ordinary bench.

(B) is a movable jaw, made to correspond exactly with the jaw (d), which is permanently attached to the frame The jaw (B) near either end is attached to the supports (c, c), which are secured in their proper places by means of the sliding guides (e, e) extending longitudinally across the frame (A) and attached at either end to the bars (e) of the guides (e), is a rod (f).

is a lever made to lit and work in slot (h) of the frame (A) and immediately below the top of said frame .is formed with two arms (g) having in them slots (g) through which the rod is made to pass; the arms (g) of the lever are pivoted to the cross piece (A) of the frame (A) as represented. So that, as the lever (g) is moved backward and forward, the supports (c, c) will receive a corresponding mot-ion, and the jaw (B) open or to contract as may .be required.

tween the jaws (B, d) in such manner as to support the board or other piece of lumber, to be wrought, the gage (20) rests at either end upon screw rods (1" 1*), these-rods (1' 1*) pass down through the pinions (n a) which are made to screw upon the rods (7 7') and are secured in their places by means of clamps (s s).

(t) is a shaft provided near each end with worms (t) by means of which the pinions (fn. a) are made to operate.

(j) is an index attached to the screw rod (r) which by means of the graduated scale enables the operator to adjust the gage, to the width required for the lumber to be wrought.

The operation of the above described invention, may be described as follows, the gage (p) will rst be adjusted in proper position with reference to width of the lumber required, this will be accomplished by turning the crank ('v) of the shaft (t) and working the screw rods up or down as may be required, by means of worms (t) and pinions (a a). This being done, the piece of lumber to be wrought will be placed upon the gage (p) and the lever (g) thrown back until the jaw (B) impinges tightly against the lumber and secures it between the two jaws, the dog (l) of the lever (g) taking into the rack (la) secures this position, a plane provided with shoes o-r stops as shown in Fig. 1 is then used, until the shoes ride upon the edges of the jaws, the upper edges of the jaws being perfectly parallel wit-h the upper edge of the gage, the board planed or jointed must be of an even width and precisely like each succeeding board passing through the same process.

What I claim as my invention and desire to secure by Letters Patent is l. The movable jaw (B) constructed and arranged with reference to the permanent jaw (b) in such manner as to secure properly the lumber to be Wrought an al the same With the scale (m.) substantially as and for 10 time to form a track o1' guide for the plane the purposes set forth.
