PETER J. JOECKEN, OF SHEBOYGAN FALLS, WISCONSIN, ASSIGNOR TO FALLS MACHINE COM- PANY, OF SHEBOYGAN FALLS, WISCONSIN, A CORPORATION OF WISCONSIN.

WOODWORKING-MACHINE.

Patented Dec. 22, 1908.

Original application filed August 80, 1907, Serial No. 890,742. Divided and this application filed March 7, 1903.

Serial No. 419,620.

To all whom it may concern: I

Be it known that I, PETER J. JoEcKEN, residing in Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented new and useful Improvements in woodworking Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in wood-workin machines, and more particularly to that c ass known as planers.

One of the objects of this invention is to provide a woodworking machine in which the depth of cut of the cutter is adjusted by raising or lowering the feed table, which table always occupies approximately the same relative distance from the radius of the cutter.

A further object of the invention is to pro vide a wood-working machine in which the feed table may be adjusted to any angle desired.

With the above, and other. objects in view, the invention consists of the machine and parts, and all equivalents thereof, as hereinafter described.

In the accompanying drawing in which the same characters of reference refer to the same parts throu h all of the views; Figure 1 is a side view 0% a portion of a laner provided with the improved adjusta le feed table; Fig. 2 is a vertical longitudinal sectional view thereof; and Fi 3 is an end view thereof.

Referring to t e drawin the numeral 5 indicates the main frame of the planer which may be made of any suitable size or shape, and 6 the rotatable'cutter mounted thereon. An adjustable supporting table 7 rests on the frame to the rear of the cutter and is adapted to support the lumber after it has been planed by the cutter. An ad'ustable feed table 8 mounted on cranked roc -shafts 9 which have their bearings 10 in the main frame is disposed above the main frame and in front of the rotatable cutter. The feed table is provided with guide strips 11 to uide the lumber being planed in the proper irection.

The front ends of the cranked rock-shafts have connected thereto

disks

12 and 13 and to the upper. portions of these disks are connected, pivotally, threaded blocks 14. A connecting rod 15 reversely threaded at its ends and rovided with a medial squared portion 16, is threaded to these blocks and is adapted to moveboth disks simultaneously when the table is adjusted vertically. An-

. other threaded block 17 is pivotally connected to the lower portion of the disk 12 and to this block is threaded an adjusting screwbolt 18 provided with a hand wheel 19 for rotating the same. This adjusting bolt has its bearing in. a bearin block 20 which is pivotally connected to a bracket 21 fastened to the main frame. A collar 22is mounted on the adjusting bolt immediately in front of the bearing block and serves to prevent endwise movement of the adjusting bolt to the right, the hub of the hand wheel providing the means for preventing movement in the opposite direction.

It will be noted that the radii of the cranked rock shafts are" equal to the radius of the cutter so that in'raising or lowering the table the end of said table adjacent to the cutter will always remain the same relative distance from the arc of movement of the cutter. The inner ends of the tables are beveled off so that the upper surfaces of the tablesmay be brought as close as possible to the cutter in order to properly support the lumber being planed.

In order. to level or aline the feed table with the supporting table the opening 23 of the bearing which surrounds the cranked portion of the crank shaft to which the disk 13 is connected, is elongated so as to permit an independent movement of this shaft, which movement will tilt the feed table to any angle desired. This independent movement of the crank shaft is accomplished by turning the connecting rod 15 by its squared medial portion, which will revolve the disk 13 and its connected crank shaft, the other crank shaft being held stationary in adjusted position by means of the adjusting bolt 18 and the disk 12. When the table has been adjusted to the angle desired, the connecting rod is locked in position by means of jamb nuts 24 threaded to the rod and bearing against the blocks 14.

In 0 eration the feed table is raised or lowere to increase or diminish the depth of the cut in planing by turning the hand wheel which will revolve the disk connected thereto, and by means of the adjustable connecting rod will likewise revolve the other disk. I This will cause both crank shafts to revolve and the cranked portions thereof upon which the feed table is mounted will be either raised of adjustments.

If it is desired to raise or lower one end of the feed table, the jam nuts are loosened and the connecting rod is turned by means of a wrench engaging the squared medial.

portion thereof. This movement will revolve the outer disk and the crank shaft connected thereto and the cranked portion of the shaft will slide in the elongated opening of its bearing and raise or lower this end of the table. \Vhen the desired adjustment is attained, the jam nuts are tightened and the feed table is in position to be used.

From the foregoing description it will be seen that a feed table and a supporting table are provided which are simple in construction and may be easily adjusted to any angle or position desired.

While only a fragment of the supporting table is shown in the drawings, it is to be understood that it is provided with the same means of adjustment as the feed table and is adapted to be operated in the same manner. These parts are marked with the same reference numerals with the prime character added thereto.

This case constitutes a division of my application for Letters Patent for improvements in wood-working machines, filed August 30, 1907, and bearing Serial Number 390,742.
