MACHINE To CUT roLYeoNAL s'RrAcEs IN T11yii`nn.

Specification of Letters Patent No. 10,346, dated December 2C, 1853.

To all whomy t may concern:

Be it known that I, ELIAS UNGER, of Dayton, in the county of Montgomery and State of Ohio,- have invented a new and useful Improvement in Machines for Dressing Timber for Cabinet Purposes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which- Figure' l, is a perspective view of the machine. Fig. 2, is an end elevation of the same. Fig. 3, is a plan of same. Fig. 4, is a face view of the clamp, `for dressing broad surfaces. Fig. 5, is a bottom view of thev same.

Similar letters of reference in the several figures denote the same part of the machine.

My invention refers to improvements in machines for dressing timber for cabinet purposes, and particularly to its adaptation to the tapering of such timber and fashioning it so as to possess a cross section of an octagonal or other polygonal shape, such as the form usually given to bed posts.

It consists in the employment ofl a slotted table carrying standards for holding' timber in the desired position, while the table is moved longitudinally so as to bring the material against the cutters 0f a rotary face plate; .the standards being furnished with eccentric points for securing the timber at the proper angle for the dress required.

In the drawings a is the slotted table movable longitudinally upon the ways r, by means of belting from the shaft t. In the slot ZJ of the table e are inserted the 'lower portions of the standards or carriages f,

which traverse the slot and are secured atV any point to accommodate the length of timber, by wedges through the lower portions of the standards or carriages, or in any suitable manner. The face plate is represented by c; it is revolved upon the shaft (Z by means of the belt g from the pulley w, and is susceptible of a lateral motion by reason of the frame in which the shaft (l rests beingl movable bythe lever 3]. The face plate is provided with two or more cutters, vinserted and acting in the usual manner. In the heads of the standards are the movable blocks g having on their faces the eccentric points c', i, the latter working with a thread in the block, and moved by the crank w; the blocks are held in position by the set screws Z. yMovable-upon the table a is the securin )late it in which is theV shaft m carrying the cam n, and movable by the lever j; the upper edge of the cama is perpendicular to the face plate c which furnishes the means of accurately squaring the timber dressed.

The operation of my improved machine is as follows: The timber to be dressed is lirst secured between the standards; in the case of bed posts, the dressing of which forms one of the most important uses of the machine, the original centers upon which they shall be perpendiculary to the edge of the,

cam. The face plate c is brought into position by a movement of the lever y, and the table a moved forward by belting from the shaft` t, or any other well known device for producing a reciprocating motion of the table; this brings the post against the 'cutters of the revolving face plate and com-l `pletes the dressing of the same as requiredr A scale may be formed on the inner face of sfo the standards for graduating the movement of the blocks g, so that the proper position may be given to the post each time it is adjusted for `dressing.V\r7hen used fordress` ing the squares of posts, the opposite'points the table. The board is secured between the" teeth p and being parallel to the face plate` 0 is dressed as above described.

This.` machine which is. intended for the A yuse of cabinet makers, is of great advantage in the manufacture of bedsteads, by reason enabling the operator to performwith eX- pedition and ease a species of labor whichy by the-ordinary mode wastediousand frequently inaccurate.

of the eccentric points and the adjustability ofthe blocks in which they areinserted; n .Y i

I do not claim` the movable table or the cutter may have any desired angle With the revolving face plate, neit-her do I claim the axis of the piece, for the purposes and in securing of timber between standards, as the manner set forth.

such are Well known; but In testimony whereof, I have hereunto. j What I do claim as my invention, and designed my name before two subscribing Witi5 sire to secure by Letters Patent, is` nesses.
