GEOFFREY wiuLlAm THomAS United States Patent M 3,269,439 WOOD-WORKING BENCHES Geoffrey W. Thomas, 7 Shaftesbury Ave., Cheadle Hulme, England Filed Sept. 23, 1964, Ser. No. 398,603 8 Claims. (Cl. 144-286) This invention relates to improvements in wood-working benches particularly for benches for use in schools and similar institutions.

Wood-working benches have been constructed with a bench top along each side and with a well separating the bench tops and with a vise along the front having a planing stop thereon.

The object of the invention is to provide a planing stop at the end of a wood-working bench opposite the vise for clamping a plank or work piece during planing.

According to the invention the device comprises a transverse rod or bar carried on a pair of arms, pins being provided on the arms to engage holes in the edges of the bench top to locate the transverse rod or bar in position for clamping a work piece for planing between the rod or bar and a vise stop.

The invention will be described with reference to the accompanying drawings:

FIG. 1 is a perspective view of a double carpenters bench showing the invention applied thereto.

FIG. 2 is a detail plan view enlarged of a portion of the bench.

FIG. 3 is a side elevation of FIG. 2.

FIG. 4 is an end elevation of same.

FIG. 5 is a side elevation of the top member of the bench showing metal strips thereon.

FIG. 6 is an end elevation of same.

FIGS. 7-9 are perspective views of three constructions of the transverse rod or bar.

FIG. 10 is a side elevation of a sash cramp.

FIG. 11 is a transverse section on line 11-11 FIG. 10.

FIG. 12 is a perspective view of a supporting bracket.

A double sided carpenters bench A is made with a vise a at opposite ends on each side, each provided with a planing stop a and with a well a separating the bench tops.

A transverse rod or bar B extends transversely of each bench top, the rod or bar B being mounted on arms b. One arm b (FIGS. 2, 3) is pivoted to the transverse rod or bar B on a vertical pin b which is prevented from being operated when the rod or bar is in use by a tail piece b on the arm engaging the side of the bench. In order to disengage the transverse rod or arm this latter is raised and the arm pivoted to free the pin or inturned end b from the hole b If desired both arms may be pivoted to the transverse rod or bar.

The longitudinal edges of each bench top are provided with metal strips C secured thereto and formed with holes to register with the holes b in the bench through which the inturned ends of the arms b extend. Alternatively, the inturned ends b may be in the form of pins secured to the arms b (FIG. 8) or with dowels b to receive removable pins b (FIG.7). The rod or bar B may be formed in two parts B pivoted together (FIG. 8) a pivot pin connecting the two parts together and a shoulder on each part to prevent them from pivoting when in use. In a further arrangement the arms b are formed with inturned ends b of differing lengths and a tail piece b (FIG. 9) to steady the rod or bar when in position on the bench but when lifted clear of the surface permitting lateral movement for the shorter end 17 to be sprung from the bench and then the longer end b to be removed. The arms b may be provided with down wardly projecting arms b to engage the sides of the bench (FIG. 3) to steady the rod or bar thereon.

3,269,439 Patented August 30, 1966 In an alternative arrangement the vise comprises a sash cramp d mounted on the end of the bench, the cramp bar 'D with the tail jaw removed passing through a slot d in a collar bracket -D mounted on the bench, a transverse slot d being formed in the bracket for the passage of a pin d by which the cramp bar is secured in the required position. The cramp bar may be adjusted in position in height by a wedge d or alternatively a thumb screw d The end of the cramp bar D under the bench top passes through a guide plate d A cramp jaw d forming a planing stop on the cramp bar D is arranged to project above the line of the bench surface and the cramp bar D is adjusted according to the length of the wood to be planed which is clamped between the r-od or bar B and the jaw a? by a screw d The rod or bar B is positioned on the bench top according to the length of the Work piece and increases the effective length of the bench as the transverse rod or bar may be arranged along the forward end of the bench top and the vise extended at the back.

Wide work pieces may be planed on twin top benches by employing one of the devices on each bench top and narrow laths may be clamped between the vise stop and the transverse rod or bar. By opposing two of the devices on the same bench and fitting one of them with a block and screw heavy pieces may be secured for carving in the round.

What I claim is:

1. A wood-working bench comprising a bench top, a vise mounted on one end of the bench, a planing stop extending upwards from the vise, a transverse bar extending transversely of the bench, arms on which the transverse bar is mounted and pivot pins on the arms for engaging holes in the sides of the bench; wood to be planed being clamped between the planing stop on the vise and the transverse bar.

2. A wood-working bench comprising a bench top, a vise mounted on one end of the bench, a planing stop extending upwards from the vise, a transverse bar extending transversely of the bench, arms on which the transverse bar is mounted and pivot pins on the arms for engaging holes in the sides of the bench, a metal strip having holes therein to register with the holes in the bench along each side of the bench; wood to be planed being clamped between the planing stop on the vise and the transverse bar.

3. A wood-working bench comprising a bench top, a vise mounted on one end of the bench, a planing stop extending upwards from the vise, a transverse bar extending transversely of the bench, arms on which the transverse bar is mounted, a pivot pin on one transverse bar connecting the arm thereto and pivot pins on the arms for engaging holes in the sides of the bench, a metal strip having holes therein to register with the holes in the bench along each side of the bench; wood to be planed being clamped between the planing stop on the vise and the transverse bar.

4. A wood-working bench as in claim 1 in which one arm is pivoted on the transverse bar, a tail piece being mounted on the arm to prevent the arm from pivoting when the transverse bar is in use.

5. A wood-working bench as in claim 1 in which the ends of the arms are inturned to form the pivot pins therefor.

6. A woodworking bench as in claim 1 in which the transverse bar is formed in two parts, a pivot pin connecting the two parts together and a shoulder on the parts to prevent them from pivoting in one direction.

7. A wood-working bench as in claim 1 in which a tail piece is mounted on the transverse bar to steady this latter when in use.

8. A wood-working bench comprising a bench top, a sash cramp acting as a vise mounted on one end of the bench, a planing stop slidable on the cramp, a screw passing through the end of the cramp to engage the planing stop, a collar bracket mounted on the underside of the bench through which the cramp is positioned, a pin passing through the bracket and through one of a plurality of holes in the cramp for securing the cramp, a transverse bar extending transversely of the bench, arms on which the transverse bar is mounted and pivot pins on the arms for engaging holes in the side of the bench; wood to be planed being clamped between the planing stop on the vise and the transverse bar.
