CARPENTERS WORK-BENCH.

SPECIFICATION forming part of Letters Patent No. 300,178, dated June 10, 1884. I

' Application filed February 26, 1884. (No model.)

To all whom it may concern.-

Be it known thatI, CLARENCE A. WILLIAMS, of Webster City, in the county of Hamilton and State of Iowa, have invented a new and Improved Carpenters Work-Bench, of which the followingis a full, clear, and exact description.

This invention relates to certain improvements in carpenters work-benches, the same relating more especially to means whereby lumber may be planed off evenly and squarejointed, as it is termed-with perfect accuracy and ease without the necessity of testing the work with a try-square, gage, or other implement. The lumber to be jointed will by this invention be held between two parallel side pieces or bars upon a support that is adapted to be raised and lowered by screw and gearing mechanism arranged to operate substantially the same as that shown and described in Letters Patent No. 289,947 and No. 289,948, which were granted to me December 11, 1883.

My present invention consists, principally, in forming the side pieces or bars at their forward ends with a securely holding the forward end of the lumber to be worked, and in providing the upper edges of the side pieces with rabbets or grooves for guiding the plane and for preventing it from cutting too deep? and, finally, the invention consists of the construction, arrangement, and combination of parts, all as hereinafter more fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of my invention, taken on the line as m of Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is a transverse sectional elevation, taken on the line y y of Fig. 2; and'Fig. at shows the preferred form of clamp for holding the side pieces from springing when short pieces of timber are worked.

B B represent the side pieces or bars of the bench A. These bars B are held a short distance apart parallel with each other at one edge of the bench A, and they are secured together at their ends by the blocks 0 C. At their forward ends the said side pieces, B B, are formed forked or V-shaped rest for or provided upon their inner surfaces with the bars B B inclined pieces a rawhich, when the are in position, form a V-shaped rest for receiving, holding, and centering the forward end of the board or piece of lumber to be jointed, andat their upper edges the side bars, B B, are provided with the grooved or rabbeted strips D.D, which serve to guide the plane E, and which may be of wood or metal; or, instead of these strips D, grooves or rabbets may be made in the upper edges of the bars BB, and thus avoid the use of separate strips; but the said strips D are preferred, since when they become worn and unfit for further use they may be removed and new strips easily put in place.

F represents the support for supporting the board or piece of lumber to be worked between the side pieces, B B. This support F fits between the said side pieces, B B, as shown, and is provided upon its under side with the board or rib F, which has the aperture to and slot 1) made in it, to receive, respectively, the arms '0 d of the traveling head-blocks or nuts G H, for raising and lowering the support, the said head-blocks G H being operated simultaneously by the vertical screws I J, substantially the same as in my above-mentioned patents, the said screws I J being revolved from the vertical crank-shaft K, and through the medium of the horizontal shaft L sets of beveled gears c p f and gear-wheels gh being placed, respectively, upon the vertical screws I J and the shafts K L, as shown in the drawings.

At suitable intervals along the length of the rabbeted strips D D the said strips D D have formed in them the orifices t 2', which are adapt ed to receive the ends of the clasp, clamp, or yoke M, for holding the side pieces, B B, from springing laterally when short pieces of boards or lumber are worked. When long pieces of lumber are worked, the side strain will come at or near the ends of the side pieces, B B,

where they are stayed to the blocks 0 G, and

in such case no clamp will be required.

Fitted in the slot j, made in the outer side bar, B, is the cam-lever or dog N, which is adapted to be turned upon pin it, so that its inner end will grasp the board or piece of lumber between the side bars, B B, and hold it from backward movement in case it should be ICO necessary or expedient to trim off the edge of the board with a draw-knife before using the plane.

The mode of using my improved work-bench is as follows: To dress or joint 21 board or piece of lumber straight and square across and to reduce it to any required width, place it between the sidebars or pieces, B B, upon thesupport F, with the front end of the board pressed firmly between the inclines a a, then press the wedge 0 (shown in dotted lines in Fig. 2) between the rearend of the piece of lumber to be worked and one of the side pieces, B. Then, with any jack-plane, jointer, or smoothing-plane that will work between the side pieces, B B, plane the board until the plane will out no more,

when it will be found that the piece of lumber is properly jointed, and this without the use of a try-square, gage, or other implement to test the work. To make the piece being worked narrower or wider, raise or lower the support F by turning the crankshaft K by means of the crank it. If it be desired to bevel a piece of lumber, set it at an angle on the supportF and secureit firmly by placing any small pieces or blocks of wood against one side of it and one ofthe side pieces B and use the plane as before; and if it is desired to taper a piece of lumber, loosen the set-screw i, which will throw the screw J out of gear, and then turn the crankshaft K, which will revolve the screw I and lift the forward end the rear end remains at rest.

of the support F, while This will set the support F 011 an incline, the slot I) permitting sufficient endwise movement of the support F, and thus support the piece of lumber, so that it can be Worked to any desired taper.

' The clamp or yoke M, as above mentioned, will be used only when short pieces of board or lumber are to be worked, and then only in rear of the plane.

If it is found necessary to use a draw-knife upon the piece*being worked, the outer end of the cam-lever N will be swung outward, which will cause its inner end to grasp the piece of lumber and hold it firmly against backward movement, so that the knife can be used upon it.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a work-bench, the side bars, B B, provided with the inclines a a, that form a V- shaped rest for holding the board or piece of lumber, substantially as described.

2. A work-bench consisting, essentially, of the rabbeted side bars, B B, provided with apertures i on their upper edges, to-.receive suitable clamps or yokes, pivoted cam-lever N in a slot in the outer side bar, and a vertically-adjustable support, F, working'between said side bars, substantially as set forth;
