PLANlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 481,371, dated August 23, 1892.

Application filed June 13, 1890.

To all whom it may concern:

Be it known that I, LOUIS T. PYOTT, a citizen of the United States, residing in the city and county of Philadelphia, State'of Pennsyl- Vania, have invented a new and nsefullmprovement in Planing-Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an attachment to the receiving-table of a planing-machine constituting an extension of the same beyond the cutter-head and over the box and journal thereof, thus affording support for the piece while being worked and adapting the machine to a greater variety of work, the attachment being also vertically movable with a part of the table, so as to adjust the depth of cut, the construction of said attachment being hereinafter set forth, and definitely pointed out in the claims that follow the specification. Figure 1 represents a perspective view of a planing-machine embodying my invention. Fig. 2 represents a vertical section on line or m, Fig. 1, on an enlarged scale, the dotted lines on the right thereof showing the same portion of the device in front sectional elevation. Fig. 3 represents a side elevation, partly in section, of a portion of the machine. Fig. at represents a side elevation, partlyin section, of a portion of the machine, certain parts being in different positions from those shown in Fig. 3. Fig. 5 represents an end view of a portion of the machine, partly sectional, illustrating the manner of securing the support to the receiving-table. Fig. 6 represents a perspective view of a portion of the machine with the support in position. Fig. 7 represents a detail perspective view of the support.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a planing-machine, which, excepting the features of my invention applied thereto, is of well-known form and construction.

B designates a block, bar, or piece of wood or metal, which is located at the side of the receiving-table O at the end of the throat O for the cutter-head D and extending beyond said cutter-head and over the box E and j ournal F of the same, forming a rest or support $erial No. 355,311. (No model.)

for the piece of wood or timber while being subjected to the action of the cutter-head.

In order to secure the rest B to the table, I employ bolts G, which occupy recesses or slots H in the outer side of the table 0 and pass through openings in the flange J at the bottom of the rest B, the lower ends of the bolts having nuts K, whereby the rest may be held in position, it being noticed that the slots H are T shape and receive the heads of the bolts in the upper limbs of said slots, it being also noticed that the slots are open, so that the bolts may be introduced thereinto from the side'of the table. The rest B is readily attachable and detachable and being level forms a steady and regular guide for the work, especially during the operation of rabbeting. It will be'seen that the rest affords a firm support for the piece of wood or timber while being worked, especially in rabbeting, and adapting the machine to a great variety work, such as panelraisin g, the rest indicating the depth of out.

To lower the receivingtable O and support 3 connected therewith, so as to adjust the depth of the cut to be made in the piece of wood or timber, a hand-wheel L, having a threaded stem, is provided, the said threaded stem being fitted in a threaded opening N in the frame of the machine. WVhen said stem is rotated in the direction of arrow 1, Fig. 4, it causes the table 0 and support B to travel in direction of arrow 2 in the same figure, therebylowering the table and support and the piece of wood or timber placed thereon a distance below the cutter-head equal to the depth of the cut required. The end of the stem M opposite to the handwheel L is swiveled to the receiving-table C, thereby raising and lowering said table, according to the direction in which the stem M is rotated.

To assist in the adjustment of the table and support, inclined ways N project upward from the frame A and are engaged by guides P, secured to the table, to thereby prevent lateral displacement and provide for a proper alignment at all times.

The extension or rest B may be adjusted to and from the part of the table to which it is attached by loosening the bolts and again tightening the same, thereby extending the bearing-surface at the edge of the table when found necessary to accommodate dilferent widths of work. This adjustment may be ac- 5 complished by means of the flange J.

It will be observed that when the extension or rest B is adjusted with the part of the table to which it is secured the remaining part of the table on the opposite side of the cutter,

10 when held in elevation, will form a guide,

2. A planing-machine having a table capable of vertical adjustment and an extension or rest adjustable to and from one edge of said table, substantially as described.

3. A planing-machine having a table capa ble of vertical adjustment with a slot in the edge thereof and an extension or rest having a headed bolt to adjustably engage said slot of the table, substantially as described.

4:.- A planing-machine having a table capable of vertical adjustment, an extension or rest with a flange attachable to said table, and means for connecting said parts, substantially as described.
