JOHN M. RICHEN-S, OF JACKSONVILLE, FLORIDA.

HAND-PLANER.

Specieation of Letters Patent.

Application led. January 7, 1918. Serial No. 210,870.

To all 'whom z't may concern.'

Be it known that I, JOHN M. RrcHENs, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Hand-Planers, of which the following is a specification.

This invention relates to planer devices, more particularly to devices of this character for planing wood surfaces, and adapted to be guided by hand, and has for one of its objects to provide a device which may be guided over the surface substantially in the same manner as an ordinary jack or jointer plane, and whereby the surface of the wood may be dressed substantially in the same manner as when subjected to the action of an ordinarv rotary planing machine.

Another object of the invention is to produce a device adapted to be operated by a suitable motor carried by the device.

Another object of the invention is to. provide a device of this character having means whereby the chips or shavings will be carried away from the cutting mechanism.

Another object of the invention is to provide a device of this character wherein provision is made for adjusting the device for operation upon curved or convex surfaces.

With these and other objects in view, theinvention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention- Figure'l is a side elevation of the improved device.

Fig. 2 is a plan view.

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 2.

Fig. 4: is a side elevation with the gear,` protecting hood detached.

Fig. 5 is a plan view with the protecting hoods and the power fandetached.

Fig. 6 is a front elevation.

The improved device is designed to operate substantially in the same manner as an ordinary rotary planing machine wherein a revolving cutter is employed in coaction with a chip breaker, and comprises a suitable supporting frame carrying guiding handles similar to those employed upon an ordinary jack or jointer plane with a rotary cutter or' planer in 'place of the ordinary plane iron or chisel, and with means, such as an electric motor, supported upon the framework and arranged to actuate the rotary cutter. The improved device likewise includes a resilient base member suitably supported from the frame with the end portions adapted to be adjusted toward and away from the frame to provide a curved shoe or sole portion to adapt the improved device to dress or plane curved surfaces. A suitable suction f-an is also associated with the device adapted to carry the chips and shavings away from the cutter and throw them laterally from the machine.

The supporting framework includes a base member having a fiat central portion 10, a forwardly and upwardly inclined portion 11 and a rearwardly and upwardly inclined portion 12. Vertically and longitudinally directed webs 13-14 extend from the base portions 10-11--12 and are spaced Patented Oct. 8, 1918,

inwardly from the outer edges of the base,

the web 14 being spaced at a greater distance from one edge of the base than the web 13. A relatively low transverse web 15 extends between the longitudinal webs 13-14 and spaced from the forward end of the base, while shorter brace webs 16-17 extend between the webs 13--14 and the Vouter edges of the base. A relatively high Rising from the inclined portion 12 of the base is a relatively wide intermediate rib 21 upon which the rear handle 22 is located. Rising from the forward end of the inclined portion 11 of the base is a central base member 23 to support the forward handle of the device. comprises a base member 24 suitably supported from the base 23 by a clamp lbolt 25, the latter likewise constituting a clamping means 'for supporting a U-shaped Standard or bracket 26 carrying a hand grip member 27. The handles 22-27 enable the operator to firmly grasp and actuate the improved device und hold and 'guide it as will be obvious.

Rigidly attached to the flat central portion 10 of the base is a resilient shoe or sole member, represented as a whole at 28, and extending forwardly and rearwardly beneath the portions 11-12 of the base. Attached to the forward portion of the member 28 is a transverse supporting cleat 29, while a similar supporting cleat 30 is attached to the member 28 at its rear end. j

The forward part of the inclined portion 11 of the base is increased in thickness at each side externally of the webs 13-14 as shown at 3l--32, and extending respectively through these thickened portions are pins 33-34. At their lower ends the pins 33-34 are received in sockets 35-36 in the ends of the cleat 29 and held from rotation therein. The thickened portion 3l is provided with' a transverse-'recess indicated. at 37, while a similar recess indicated at 38 is formed in the thickened portion 32. The outer portion of the pin 33 is threaded, and engaging this threaded portion within the recess 37 is a disk nut 39, while a similar disk nut 40 engages the threaded portion of the pin 34 within the recess 38. The faces of the nuts 39-40 are milled or roughened `and project for a short distance beyond the outer face of the portions 31-32, so that the pins may be rotated by manipulating the disk nuts. By this means the forward portion of the sole member 28 may be adjusted nearer orfarther from the inclined portion 11 of the base, and thus cause the member 28 to assume a curved or segmental form.

The rear part of the inclined portion 12 of the base is increased in thickness externally of the webs 13--14 as shown at 41--42, and extending respectively through these latter thickened portions are pins 43-44. At their lower ends the pins 43-44 are received in sockets, one of which is shown at 45, in the ends of the cleat 3() and held from rotation therein. The thickened portions 41--42 are provided respectively with transverse recesses 4748. The outer portion of the pins 43-44 are threaded, and engaging these threaded portions within the recesses are disk nuts 50-51. The faces of the nuts 50-51 are milled or roughened and project for a short distance beyond the adjacent faces of the thickened portions 41--42 so that the pins 43-44 may be rotated to ad just the rear portion of the member 28 farther from or nearer to the inclined part The forward handle i 12 of the base. By this means the unsupported forward and rear portions of the sole member 28 may be adjusted to cause them to assume afcurvcd shape and thus adapt-J the device to planing curved surfaces.

A set screw, indicated at 33 is tapped through the portion of the/.frame adjacent to sole adjusting pins and engages the pins and serves to lock the pins and the sole member in adjusted position.

Formed upon the central flat portion 10 of the base externally of the webs 13-14 are bearings indicated as a whole at 52- -53, and mounted for rotation through these bearings is a shaft 54 which carries the cutter part of the improved device. The bearings 52-53 are preferably provided with ball or roller bearings indicated at 55, to reduce the friction. v

The cutter part of the improved device comprises a head portion 56 mounted for rotation with the shaft 54, and formed with a plurality of longitudinally directed recesses or seats 57, the side walls of the rccesses extending tangeutially of the head 56 and likewise converging inwardly. Any required number of the seats 57 may be employed but for the purpose of illustration six of the seats are shown and uniformly spaced as shown in Fig 3. The cutters or knives are represented at 58 and engage respectively in the seats 57. Bearing in each recess 57 is a binder member 59 converging toward its inner edge, or slightly Wedgeshaped, and bearing by its side faces respectively against the adjacent face of the knife 58 and the inclined wall of the recess. By this arrangement it will be obvious that the knives 58 may be firmly anchored in position within the recesses, and may be adjusted therein by slightly changing the location of the holding members 59 and firmly hold them in position. Clamp bolts 60 are tapped into the head 56 adjacent to the recesses 57, and each provided with a lateral head bearing over the outer edge of one of the members 59. It will thus be obvious that the member 59 may be clamped into position and firmly forced against the nives 58, so that the knives may be firmly supported and prevented from displacement during the rapld Inotion of the cutter head. The shaft 54 is so located that the cutting edges of the knives 59 as the head is rotated operate consecutively through the opening 19 and coact with the chip breaker 20 to produce the cutting action.

`Rising from the flat central portion 10 and the inclined portion 12 of the base are bearings 61--62 in which a counter shaft 63 is mounted for rotation. The bearings (i1-62 are preferably provided with antifriction balls or rollers indicated at 64, to reduce the friction. 4

The shaft 63 extends at onerend beyond 65 and 68 and the bearings 53--57.

the bearing 62, and is provided with a driving gear which engages with a pinion 66 on the shaft 54. By this means it will be obvious that when the shaft 63is rotated its 6 motion will be transmitted to the shaft. 54

and the cutter head carried thereby, and at increased speed.

Any suitable means may be employed to impart motion tothe shaft 63, but prefer ably an electric motor, indicated'conventionally at 67, will be employed and mounted upon the frame, preferably upon the webs 13-14, as shown. The shaft 68 of the motor is extended and carries a pinion 69 which operates in engagement with thegear 65. By this mea-ns the motion of the motor is communicated to the gear 65 and thence to the cutter head. The conductor wires of the m0- tor are indicated conventionally at 70 and are of su-iicient length to enable the improved device to be moved the required distance when being operated.-

Supported upon the transverse webs .l5-18 and the adjacent portions ofthe webs 13--14 is a hood or casing represented as a whole at 71, the hood being extended at its upper part into a wind trunk 72. At one end of the wind trunk is a fancasing 73 carrying a suction fan indicated at 74, the wind trunk leading into the fan casing as' shown. l

The outlet 75 of the fan casing is referably arranged to discharge lateral y and downwardly as shown in Figs. 1,2, and 4.

The shaft 76 ofthe fan extends through the casing 73 and is provided with a belt Enlley 77, while the shaft 54 of the cutter ead is provided with a similar belt pulley 78, the belt pulleys arranged to receive a driving belt 79.

By this arrangement it will be obvious that the suction fan will be actuated from The base portion, the variousjwebs, the

supports for the 'handles and the thickened portions through which the adjusting pins operate, ane integral, and preferably cast of aluminum or the like to combine strength with li htnessj 4 A suitable protection hood, indicated as a whole at 80, is arranged to cover the space between the web 13 and the outer edge "of the base and extended upwardly asshown at '81 and 82 to bear over and protect the ears 64, he hood .70 is secured by screws or like devices 83 to .closure to said chamber, and means for caus- ,tween the longitudinally directed webs, said the framework of the device.v A similar hood represented as a whole at 84 extends over the space between the web 13 and the base of the device, and thus covers and protects the bearings 52-61.
