SPECIFICATION forming part of Letters Patent N 0. 694,314, dated February 25, 1902.

Application filed May 31, 1901. Serial No. 62,535. (No model.)

To all whom it may concern.-

Beit known that I, OHARLEs W. H. BLOOD,

a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, 5 have invented an Improvement in Planing- Hachines, of which the following description in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to planing-machines, and has for its object the provision of means for adjusting the platen and feed-rolls vertically either simultaneously or separately, the simultaneous adjustment being for the pur 15 pose of causing the cutter to take a deep or shallow cut, as the case may be, and the separate adjustment being to take up wear.

My invention relates to that class of planing-machines in which the lower horizontal 2o cutter is not adapted for different depths of cut, but the adjustment takes place in the bed of the machine. This arrangement is of special advantage for many reasons, and the mechanism which I have herein shown and 2 5 which will be more particularly described later on eifects its objects by means of an inclined surface or Wedge action, the platen resting on an inclined projection or portion of the bed, and the journal-boxes of the feed-rolls being similarly provided with wedge-shaped supports, while also the idle roll at the front of the machine has the same general provision. In the drawings, in which Ihave illustrated a preferred embodiment of my invention, 35 Figure 1 is a vertical longitudinal section taken substantially on the irregular line 1 1, Fig. 3. Fig. 2 is a transverse vertical sectional detail to be referred to. Fig. 3 is a horizontal section taken substantially on the 40 broken line 3 3, Fig. 1, the platen being omitted.

It will be understood that the general details of the machine may be of any usual or preferred kind, there being herein shown 5 merely sufficient of said details to enable my invention to be readily apprehended.

On the frame of the machine I provide a bed to, having an inclined upper surface 0. and extending preferably entirely across the machine, as is clearly shown in Fig. 3. Resting on the surface a is a platen-wedge a having a lower inclined surface corresponding in pitch to the surface of, its upper surface being horizontal for' carrying a platen proper, p. The lower feed-in rolls of the machine are indicated at b I), being driven in usual manner by a pinion b meshing with gears b b thereof, said rolls having their journal-boxes b b mounted in vertical Ways a a in the frame ofthe machine(see Fig.3)and extendinginwardly beyond s'aid ways to be engaged by wedge-blocks a a These wedgeblocks are supported on slide-plates a resting on ways aat the opposite sides of the machine, limited in its forward movement by bolts a, and are shown as adjustable thereon by means of slots a and bolts a a. At its forward end the platen-wedge a has cars a, receiving a pivot-bar a to which links a are connected. At their opposite ends the links a are pivoted on a cross-bar a, secured at its ends in ears (1. of blocks (1. mounted on the slideplates a and shown as adjustable thereon by slots a and bolts 60 00 At their front ends the slide-plates a are connected by means of a bridge-piece a, in which is swiveled an operating rod or bar 023, having suitable engagement, as by means of screw-threads, with the frame of the machine and provided at its front end with suitable means for operating it, herein shown as a squared end to receive a crank.

At its front end the machine is provided with a usual idle roll 0, which also is made adjustable vertically in order that it may be simultaneously adjusted with the platen and feed-rolls, having for this purpose-its journalboxes 0', carried in vertical ways 0 of the bedframe, said journal-boxes being supported on wedge-blocks a, connected by rods or links with the bridge-piece 00 said rods being adjustable in the latter by means of the threaded ends for the purpose of independent adj ustment separate from the other parts of the connected mechanism.

The platen-wedge a may be locked in its adjustment by any suitable means, being herein shown as provided with a special clamp comprising bars a, resting on ledges c0 projecting from the inner sides of the walls of the platen-wedge a connected by bolts 0. with a series of clamping-blocks a resting at one end (1 against the under side of the projection a and at their other end being engaged by a rock-shaft at, having a flattened side, as is clearly shown in Fig. 1, said rock-shaft being operated by a crank (r connected by links 60 pivoted at their forward end at 01, to an operating-lever 60 the object thereof being to provide adjacent the front end of the machine the operating means of the parts when it is desired quickly to raise or lower the various parts, as will readily be understood.

From the above description it will be apparent that whenever it is desired to raise or lower the various rolls and platen the latter is simply unclamped by bringing the lever (r to the position shown in Fig. 1 and then turning the operating-rod 0,23 one way or the other, as the case may be, so as simultaneously to pull or push the various parts along, thereby causing the platen to rise or lower by its movement along the inclined surface a and causing the journal-boxes b b and c to rise or lower by the movement thereunder of the wedge-blocks a, a and a fl'respectively. If, on the other hand, any of these parts for any reason change their relative positions as, forinstance,by the wear of the parts-they may be independently adjusted, the platen being adjusted relatively to the other parts simply by moving the blocks or. one way or the other and either feed-roll being adjusted by sliding the wedge-blocks a a or any of them, one Way or the other along the plate a on the bed of the machine, and so the idle roll may be adjusted by adjusting either or both of the blocks 0, by means of the threaded rods a It will be seen that by reason of the various bolts a 03 the parts are kept in rigid adjustment and prevented from slipping.

While I have herein described my mechanism in all its preferred details, I wish it understood that I am not limited thereto, as various changes and other arrangements may be resorted to within the spirit and scope of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, a machine-frame,a horizontally-movable platen,horizontally-stationary feed-rolls, and means moving horizontally for vertically adjusting the feed-rolls and horizontally moving the platen, and cooperating means causing a vertical movement of the platen to result from its horizontal movement.

2. In a machine of the kind described, a platen,a support therefor,said support having an inclined upper surface, means for causing relative horizontal movement of said platen and support for adjusting the platen vertion said slide-plates, a plurality of feed-rolls vertically movable in the frame and supported therein-on said wedge-blocks, and means for moving said slide-plates longitudinally of the frame of-the machine.
