ADJUSTABLE TABLE FOR SHAPlNG-MAGHINES.

SPECIFICATION forming part of Letters Patent No. 305,922, dated September 30, 1884:.

Application filed January 2S, 1834. y (No modeLl To @ZZ whom it may concern:

Be it known that I, HENRY J. HENDEY, of Torringtominthe county of Litchfield and State of Connecticut, have invented new Improvements in Adjustable Table for Shaping- Machines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon,` to be a full, clear7 and exact description of the same, and which said drawings constitute part of this specification, and represent, iny Figure 1, a side View; Fig. 2. a front View; Fig. 3, a transverse section through line x .12, lookingdown; Fig. 4, aperspectiveview ofthe shaping-machine, the vertical work-plate oonstructed to receive the adjustable table, the table removed; Fig. 5, a perspective view of the adjustable table, having a work holder applied.

This invent-ion relates to animprovenient in the work holding plate or table for that class of metalworking machines commonly called shaping-machines,7 applicable to other metal-working machines which employ a horizontal work -holding table7 and which table is made adjustable in guides up and down and to the right and left with relation to the tool', the holder carrying the tool having a reciprocating movement imparted to it to operate upon the work secured to the table. In Fig. 4 I illustrate such a shapingmachine. The work-holding plate is arranged upon horizontal guides,` and the horizontal guides on vertical guides, so that the workplate may be adjusted to the right and left or up and down with relation to the tool. The toolholding head is arranged upon a longitudinal carriage to which a back-and -forth reciprocating movement is imparted. construction of machine is too well known to require more than illustration, in view of the fact that my improvement relates only to the work table. As shown in Fig. et, the workplate presents simply a vertical surface. In some cases the work-plate has a horizontal table extending from it, presenting a surface to hold the work parallel with the path of the cutter. It frequently occurs that the surface to be operated upon bythe tool is inclined to the opposite surface of the piece to be wrought.

This Y the work-table so that it may be adjustable to any desirable inclination with relation to the moving tool.

To this end my inventlon consists in hinging to the vertical work -plate a removable auxiliary work-table, the point of hinging be-.

ing at the inner end of the auxiliary Worktable, the auxiliary table having au extension of a brace-like character downward and rearward, with an adjusting screw in the foot, arranged to takeits bearing upon the vertical work-plate, and so that by turning the screw the table may be set at any desired angle with relation to the path of the moving tool, the table turning upon its hinges as its center of motion, as more fully hereinafter described.

A represents the vertical work plate, arranged upon horizont-al guides, and adjustable thereon in a path at right angles to the pathY of the moving tool7 the horizontal guides carrying the work-plate arrangedv on vertical guides,`so as to'be vertically adj ustable'tow'ard or from the tool, in the usual manner for this class of machines.

B is the auxiliary work-table, made separate from the work-plate A. At the rear or inner end the table is constructed with ears or lugs C, and by which, by means of screws D, the work-table is hinged to the vertical plate, as seen in Fig. l, the screws forming pivots upon which the work-table may turn as a center of motion. From the under side ot' the table a downward extension, E, of a brace-like character is made. On the rear side of this downward extension isa vertical rib, F,which tits into a corresponding groove in the vertical plate A, and so that when the foot of the downward extension or brace rests against the vertical plate A and the rib F in its-groove the table stands firm, and substantially as does the horizontal work table when made a permanent or inadjustable part oi' the vertical IOO work plate, as in the usual construction. Through the foot of the downward extension E a screw, G, is introduced, and so ask to take a bearing on the vertical plate A. It is provided at its outer end with a suitable hand wheel or head, H, by which it may be conveniently turned. Suppose it be desired to work` an inclined surface. Turn the screw Ginward, which will force the foot ofthe downward extension E outward, and correspondingly raise the front of the auxiliary table,las seen in broken lines, Fig. 1, until the required inclination is attained. The screw forms a sufiicient bearing for the brace,and so that the auxiliary work-table will be held by its pivots strong and firm for the performance of the work. By thus constructing the auxiliary Work-table it may be adjusted after the work is secured to it, or its inclination changed any time during the work, and without the necessary removal or change of position of the work upon the table. At the same time, if the table be required horizontal and in a plane parallel with the path of the tool, the adj listing-screw is turned to bring the table to that position, and then it works the same as in the common fixed horizontal table. When the vertical work plate is required, the auxiliary table is easily removed by withdrawing the screws D, the face of the plate being provided with the usual T-shaped grooves, l. The

to said vertical plate A, and constructed with a downward extension over the front of the vertical plate, with an adjusting-screw, G, at therfoot of the extension, substantially as described, and whereby said auxiliary work-table may be turned upon its hinge and set at different angles -with vrelation to the path of 45 the tool. t

2. The combination, in a shaping-machine, of the vertical work-plate A, the auxiliary work-table B, hinged thereto, said table constructed with a downward extension, E, over the front of the vertical work-plate, the lower end of said extension provided with a vertical rib, F, and the vertical work-plate with a corresponding groove to receive said riloVF, and the adjusting device, substantially such as described, to turn said auxiliary table upon its hinge to set it at different angles to the path of the tool. f
