To all whom it may OOILOGIIL:

Be it known that I, THOMAS A. human, a citizen of the United States of America, and

a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Planingi\lacliiiies, of which the following is a specification.

This invention relates to planing-machines,

ro and has for its object the production of a machine in which a special tool is provided and mechanism supporting said tool which may be actuated at the end of movement of the tool in either direction to change its angle 15 and cause a cutf'ng in either direction of movement of the work upon which said tool is operating.

The invention consists in certain novel features of construction and arrangement of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents a side elevation of a planing-machine embodying the features of this invention. Fig. 2 represents a front elevation of the tool-supporting head. Fig. 3 represents a vertical section on line 3 3 on Fig. 2. Fig. 4 represents a plan of the same. Fig. 5 represents a partial horizontal section on line 5 5 on Fig. 3. Fig. 6 represents a plan of the upper end of the tool-support in diagram. Fig. 7 represents an elevation and plan of the end of the working tool in position to operate upon the work when being fed in the direction in dicated by the arrow, and Fig. 8 represents similar views of the same tool in position to operate upon the work when being fed in the opposite direction.

Similar characters designate like parts throughout the several figures of the drawmgs.

1n the drawings, 10 represents the main frame of a planer of any well-known con struction, while 11 is the work-supporting bed movable longitudinally of the frame 10 in any well-known manner. To the cross rail 12 of said planer is secured the head 13, to the front of which is secured by suitable bolts H the tool-holder 15. The holder 15 has cut thcrcthrough a vertical slot 16, the width of which is equal to the diameter of the shank 17 of the tool-support 18, the

lower end of which is spherical, as at 19, and provided with a recess for the insertion of 5 5 the working tool 20. The lower end of the slot 16 is provided with a recessed socket 21, adapted to iit the spherical end 19 of the tool-support 1S and provide a universal joint therefor.

The upper end of the shank 17 has a bearing in a slide 22, the lower face of which is concentric with the center of the spherical end 19 and is slidable upon the outer concentric surface 23 of the tool-holder 15. The shank 17 has secured to its outer end the nut 24 and check-nut 25, by which the friction upon the slide 22 and end 19 may be adjusted.

The upper end of the slot 16 is elongated longitudinally of the planer and tapers grad- 7o ually to the recess 21. To the face of the upper end of the shank 17 is secured a grooved plate 26, with the groove 27 of which a pin 28 engages. This pin is secured to the member 29, pivoted at 30 to a slotted support 31. The pivot 30 is provided with a nut 38*, by which said pivot may be adjustcd longitudinally of the slot- 32 of said support 31 to vary the movement of the tool, as will be hereinafter described.

Slidable upon the member 29' is a member 33, the outer end of which is provided with a hole 341, engaging a pin 35, supported by a lever 36, pivoted at 37 to the car 38, extending from the head 15. The upper end of the 8 5 pin 35 is provided with a block 39, to which is pivoted the links 10, the opposite ends of which are pivoted to a block 11, secured to or forming a p art of the upwardlyextending lever 12, mounted upon an oscillating shaft 43. The shaft 13 is provided with a lever 14, to the outer end of which is secured a rod &5, upon which is adjustably secured a sleeve 4.6, said sleeve being pivoted to a friction member 17, provided with a pin 18, which limits 9 5 the movement of the friction device 47 in either direction by coming in contact with the pins 49 50. This friction device is the same as will be found on any well-known planer and affords a ready means of operat- Ico ing the rod -15 to oscillate the shaft 43, which is mounted in suitable bearings 51 upon the tool-head 15. The slot 16 is provided with a lateral opening 52, communicating therewith and extending through the wall of the head 15, and the shank 17 is provided with a ported by a chain 61, is provided, which ma be inserted through thehole 62 in the head 15 and through the slot 62* in the shank 17, this slot 62* being of such a length as to per- I mit the shank 15 to be freely moved in a vertical plane, but making it impossible to turn the same upon its axis when said pin 60 is inserted in said slot. The movement of the actuating parts in excess of the movement of the tool-support 17 when thus blocked is cared for b y the friction device 47 in a wellknown manner.

' The lateral and vertical feeds to the head form no feature of the present invention, and may be constructed and operated as in any well-known planing-machine, and for this reason in order to simplify the understanding of lateral projection 53, which extends into this opening 52.

To suitable ears 54 upon the head 15 are secured adjustable stops 55, which limit the horizontal movement of said projection 53 when moved about the axis of the shank 17. j The end of the tool 20 is of the shape shown in the lower part of Figs. 7 and 8, and either corner 56 57 is adapted to out upon the Work passing beneath the same according to the vertical angle of said tool 20, as indicated clearly in Figs. 7 and 8that is, when the bed 11 is traveling in the direction of the arrow 58 with work secured thereto and passing beneath the tool 20 the edge 56 will operate upon said Work to cut the same. When, however, travel of the work is reversed and is moved in the direction indicated by the arrow 59 on Fig. 8, the cutting edge 57 will coact therewith and perform the same operation in the reverse movement. This reversal of the vertical and horizontal angles of the cutting-tool 20 is accomplished by means of the devices heretofore described through the medium of the oscillating fric tion member 17 acting upon the rod 45 to produce an oscillation of the shaft 43. The oscillation of this shaft 43 causes the pin 35 to be moved horizontally toward or awa from the head 15, thereby causing the member 29 to be moved about its pivot 30. his movement of the member 29 will cause the pin 28 thereon to operate against the side walls of the groove 27. This action of the pin against the wall of the groove 27 will tend to move the shank 17 from the position shown in Fig. 3 into its opposite position with its front side against the opposite wall of said recess 16. As soon as the shank 17 reaches 1. In a planing-machine, the combination the limit of its vertical movement about the with a tool-holder suitably mounted in the socket 21 a continuation of the movement frame thereof, of asingle working tool having of the pin 28 against the wall of the groove two cutting edges oppositely inclined from a 27 will cause the shank 17 to be rotated about vertical face common to both and adapted to its aXis, moving the projection 53 from the cut in either direction, and means for changposition shown in Fig. 2 to the opposite side ing the angle of said tool-holder about its of said opening 52 to cause its opposite face longitudinal axis at the end of the movement to contact with the end of the adjustingin either direction to change the angle of said screw 55 at the left of said figure, this movecommon face to the work and alternately ment causing the working tools 20 to be bring a different cutting edge into operative moved into the position indicated in Fig. 7. position.

A reversal of these movements will cause the 2. In a planing-machine, the combination tool 20 to be moved into the position indiwith a tool-holder suitably mounted in the cated in Fig. 8 and shown throughout the frame thereof, of a working tool adapted to figures of the drawings. By adjusting the cut in either direction, and means for changmember 29 in the support 81 so that the pin j ing the vertical and horizontal angles thereof 28 will be on the opposite side of the axis of j at the end of movement in either direction. said tool-support 18 the movements of said 3. In a planing-machine, the combination members will be reversed. When it is dewith a tool-holder suitably mounted in the sired that a channel should be cut into the frame thereof, of a working tool supported work of the width of the working tool 20, it is thereby adapted to cut in either direction, obvious that the horizontal angle changing j mechanism cooperating with said working is not desirable and that the vertical angle j tool for moving it through a vertical angle, change is all that is necessary. To prevent stops for limiting said vertical movement,

this horizontal angle change, a pin 60, supand means cooperating with said mechanism thereof are omitted from the drawings.

In order to strengthen the spherical end 19 of the tool-support 18, it is provided with a transverse member 63, having a head 64 on one end thereof, while the other end is threaded to receive a nut 65, by which said member may be secured in position to prevent the splitting under strain of said tool-support when the tool 20 is in operation. The member 63 is provided with a hole 66, through which the tool 20 is inserted, this tool 20 being held in position therein by means of the set-screw 67. This forms an important feature of this invention, as it strengthens the tool-support and prevents it from becoming injured and making the planer inoperative.

It is believed that from the foregoing the operation of the invention will be thoroughly understood without any further description.

I claim the present invention many of the elements.

for causing said tool to be moved through a horizontal angle.
