PLANIN'G-MACHINE.

SPECIFICATION forming part of Letters Patent No. 364,329, dated June 7, 1887.

Application filed Septcmlicr 6, i896. Serial No. 212,7:6. (No model.)

To aZZ whom it may concern.-

Be it known that I, SOLOMON A. WooDs, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have made a new and useful invention relating to Planing-Machines, of which the following-is aspecification.

My invention relates to machines for planing wood and lumber; and it consists in certain new and useful constructions and combinations of theparts thereof, substantially as here inafter described and claimed.

In the drawings, Figure 1 is a top plan view 'of a portion of the cylinder, pressure-bars, and

the boxes and driving-pulley for the cylinder of a planing-machine. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical section of the same on the line at 00, Fig. 1. Fig. 4. is a side view of one of the sliding blocks which carries the pressurebar.

A is the bed-piece of the machine.

B is the planingcylinder, designed to dress the lower surface of the board passing through the machine. It is mounted upon a shaft, 1), passing through the boxes I) b, which are bolted to the ends of the bed-piece A. The pulley O, mounted upon the shaft b, drives the planing-cylinder from any suitable counter-shaft. It is understood, of course, that the bed-piece A is mounted upon suitable frame work or legs to sustain it on the floor of the building.

The upright If at each end of the bed-plate supports the sliding platen D, which is moved up and down by the screw (1, journaled in the cross-bar d, which connects the uprights b at their upper ends on the opposite sides of the machine, extending transversely across .it

above the platen.

The screw (Z is provided with the bevel-gear d at each end of the platen, which is revolved by the bevel-gear dflmounted upon a horizontal shaft, (1, which extends across the machine in the usual manner, and is supported in boxes upon the upper ends of the uprights D The construction of these parts is well known and will be understood without further description.

E E are the pressure-bars on each side of the planing-cylinder B, and it is in the manner of mounting and adjusting these pressurebars that my invention consists. The ends of the pressure-bars and the method of mounting the same are alike in all essential partie ulars, and adescription of one of them will therefore be all that is necessary to understand the invention.

. Upon the inner end of the cap of the shaftbearing box I) is an elevated block, b", ofrect angular form, projecti ug horizontally from the side of the box for some distance along its inner end. This block serves as a flat bed over the inner end of the box, which can be removed to take off the cap of the box and the cylinder. Upon this block is mounted asecond L-shaped block, 0, having an elongated slot or hole, 0, through its flat portion, anda screw-bolt, c, with a washer under its head, passes down through this slot and is tapped into the block b. The vertical part of the block claps over the inside face of the block b",and has in'ita mortise open on top and toward the pressure-bar, and a tenon on the pressure-bar fits loosely into this mortise, being of considerably less depth than the mortise, so as to allow the pressurebar to be adjusted up and down in the latter. This tenon is lettered e, and the mortise e, as shown in Fig. 1. A screw, 0 is tapped through the tenon of the pressure-bar and rests on the lower wall or face of the mortise, thus sustaining the pressure-bar at any desired height. A check-nut, e, engages with the thread of the screw 0 and serves to bind the pressure-bar in any desired position upon the screw. A second elongated slot, 0 (shown in dotted lines in Fig. 1,) cut vertically through the sliding block e has a binding-screw, e tapped into the frame-piece A below it, and passing freely through the slot. The object of forming this block L-shaped and mounting ,it on block I), as described, is to provide a simple and convenient support for the bar E, which can bring it very close to the cylinder and allow it to be vertically adjusted within the least possible space between the end of the cylinder and its box, thereby materially narrowing the machine-frame without narrowing its out, and also allowing the platen D to be brought very close to the cutter for dressing thin stuff. The opposite end of the pressure-bar is provided with a similar L-shaped sliding block combined by similar screw-bolts with the frame-work of the machine.

By loosening the serewbolts e e the presstoo ure-bar E may be adjusted nearer to or farther from the planing-cylinder horizontally, and by adjusting the screws 6 the height of the pressure-bar with relation to the planing-cylinder and the pressure-bar on the opposite side of it may be adjusted, and I thus provide a simple and cheap method of accomplishing these necessary adjustments. The blocks 6, being adj list-able independently of each other and not extending across the machine, give more room to make the pressure-bar rigid by giving it greater depth.

What I claim as new and of my invention 18 1. The combination of the lower planingcylinder, B, the pressure-bar E, vertically adjustable in the independent sliding blocks 6, and the latter made horizontally and longitudinally adjustable upon the framework of the machine.

and to adjust and secure said sliding blocks 7 horizontally and. longitudinally to the framework of the machine at each end of the pressure-bar, substantially as described.
