. 1 Claim. 1
This invention relates to planers, is particularly concerned with portable planers, is more particularly concerned with hand operated portable power driven planers, and is most particularly concerned with a depth regulating device for a hand operated portable power driven planer.
In the prior art there are hand planers of various designs, and of various types of construction, and these are adapted for either general planing use or for specific planing operations. Since these are manually operated they are not adapted for modern use inasmuch as present day methods of building construction call forspeed and great efficiency.
There also are power operated planers but these are stationary and are adapted particularly for factory use and do not lend themselves to transporting to a location, for example, where a residential dwelling is being constructed. Portable power driven planers are had but these are of such cumbersome and unwieldly construction that they often require the services of two workers t perform an operation. Another serious objection found in such planers is the cumbersome depth regulating device whereby it is not only difficult to adjust the depth of the cut of the planer but close tolerance adjustments are substantially impossible. There are also other serious disadvantages of such portable power driven planers and their use is greatly limited for a number of reasons,
It is therefore an object or" this invention to provide a portable planer. It is a further object to provide a portable, power driven planer. It is still a further object to provide a hand operated, portable, power driven planer. It is a further object to provide a depth regulating device for a hand operated, portable, power driven planer.
I have now discovered and invented a planer comprising a base, the said base having a longitudinal flat surface, an electric motor, the said motor being secured to the rear portion of the said base, a plurality of blades, the said blades being mounted about a rotatable shaft, the said blades and the said shaft being mounted forewardly in respect to the said motor, a planer head helical gear, the said gear being secured to one end of the said rotatable shaft, a motor shaft helical gear, the said gear being secured to the said motor shaft, a longitudinal shaft, the said shaft having secured thereto a helical gear at each end thereof, one of the said helical gears on the said longitudinal shaft meshing with the helical gear secured to the motor shaft and the other said helical gear on the said longitudinal shaft meshing with the helical gear secured to the planer blade shaft, and the said planer being adapted for manual movement during the operation of the motor and the blades thereof, and I am now able to avoid the disadvantages of the prior art and am able readily to accomplish the objects set forth.
Referring to the drawings: Fig. 1 is a top view of the planer of my invenprovided for planing a surfaceV at an angle to another surface.
Fig. 8 is a right side view of Fig. 7. The flat surface l of the planer extends forewardly from the extreme rear portion of the' said planer to an open space where* the blades 44 protrude. surface along the adjusting mechanism 54. The side wall 2 of the planer rises irregularly along the right longitudinal edge of the flat surface I and is perpendicular to the said surface. The side Wall 3 of the planer, likewise, rises irregularly along the left longitudinal edge of the flat surface I and is perpendicular to the said surface. The said left wall 3 of the planer has an offset 4 as is shown in the Figs. 1, 2, and 5. The bottom surface of the said offset 4 is designated by the numeral 4d. y The purpose of the said offset is to allow the blades 44 to plane to a square shoulder on material in the process of manufacture.
The electric motor 5 is mounted on the frame of the planer and is secured to the said frame by means of a plurality of screws passing upwardly through a base secured to the frame of the planer and held thereto by means of the screws Il and the slotted nuts I8, and through the cantilevered supports l5.
The electric cord 6 leading to a source `of electricity passes therethrough the handle 9-10;
passes through the switch housed in the said handle, and terminates at the motor. The trigger switch l2 can be operated by holding the same closed, or it may be locked in place by means of the push pin i3. The locking catch which is attached to the push pin I3 is designated by the numeral i4. One of the wires leading from the cord 6 passes through the handle, is attached to the binding post la, and the other wire is attached to the binding post 8a.' The screws Il hold the two parts of the handle 9|0 together. The holes I9 and 2i) inthe motor 5 are for ventilating purposes.
There is a continuation of the flat The cover plate and bearing support of the motor end is designated by the numeral 2 i. The cover plate and bearing support of the planer head end is designated by the numeral 22.
As shown in the Fig, 3, the helical gear 23 is secured to the motor shaft 23a and rotates at 17,000 R. P. M: The helical gear 23 meshes with the helical gear 24. Both the helical gear 23 and the gear 24 have the same pitch diameter and consequently both have the same R P. M. The gear 24 is secured to the driving shaft 34 by means of the set screw 26. The helical gearI 29 is secured to the driving shaft 34 by means of the set screw 32. The helical gear 29 meshes with the planer head helical gear 35 and the' pitch diameter of the gear 35 is two times the pitch diameter of the helical gear 29. Therefore the gear V35 revolves one-half the R. P. M. of the gear 2s. The a. P. M. or the gear 2s is 17,000, and of the gear 35 it is 8,500 R. P. M. The gear 35 is secured to the planer head shaft 36, turning the Y planer head 42 at 8,500 R. 13.171. The planer head 42 is secured to the planer head shaft 66 by the f s et screws 43:. The planer head shaft 36 revolves in ball bearings enclosed in the bearing case 39.
- The helical gears 23 and 24 are housed in the cover plate and bearing support 2i. The gear 26 v and the gear 35 are housed in the cover plate and bearing support 22.
ArIhe planer head shaft 36 is supported by the ball bearing cases 39 and the planer head 42 is secured thereto by the set screws 43. The blades 44 are secured to the planer head 42 by means of the screws and nuts 41. Each of the said blades has a slot 45 and a locking pin 46 which pin is rivetedin the screws 41, passesV through the slot 45'and is inserted in the planer head 42. The vert tical sheet metal covering 43 and 49 forms the planer head member. The angle bracket is Hwelded to the covering 48. The screw 5I secures the anglev bracket 59 to the offset 4 on the side wall 3 of the planer. The shaving discharge throat 52 is composed'of the hood 53 Awhich is secured to both covering 48 and the covering 49. The'member 54 is movably secured to the planer,
and is the depth adjustingmechanism of the planer. "The ladjusting lever 66 is movably secured to the boss 56. The boss 56 is machined to an inclined plane on the upper portion thereof.
a '.Ihe. said boss 56 is integral with the adjusting member 54. c lslidable on the two inclined sliders 51. 'Ihe said The said adjusting member 54 is Asliders 51 are integral with the side walls 2 and 3 of'the planer. The angle fittings 58 are secured to the sliders 51 by means of the screws 59. The "said adjusting lever is rotatably secured to the 'boss 56 by means of a fulcrum pin 62. The said pin 62 is riveted in the lever' 60 and secures the said lever 60 to the boss56. The said lever 60 has a pin 64 riveted therein and extending is secured to the member 54 and is used for manually holding the said planer with one hand during the'operation.
In'the Figs. 7 and 8, are shown the members provided for planing a surface at an angle to an- Afother'surface The facing plate 65 is secured to thev levers 66. The leversv 66 are hingably secured to the attaching plates 61 by means of the "'-fulcrum bolts and nuts 69. The bolts 68 secure the said attaching plates 61 to the said wall 2 of Cil the planer. The holes 10 which are shown in the Figs. 1, 2, and 3, are used for the attachment of the said members hereinbefore described.
In the operation of the planer of my invention the electric cord 6 is connected to a convenient electrical outlet and the' right hand of the operator grasps the handle 9-(0. The second nger of the operators hand extends forward and beneath the handle 9-I0 to press against the trigger switch I2 to complete the circuit. The index nger of the operator pushes down the push pin to lock the locking catch into locking position. The left hand grasps the handle 1I to guide and steady the planer. When the motor 5 is running said adjustment can be of extremely close tolerance. The adjustment furthermore can be made rapidly which adds greatly to the economy of the operation of the planer.
I claim: A depthadjusting device, in combination with a planer, comprising a at base, the said base Y being forwardly disposed in respect to the said planer, an inclined foundation, the said foundation being integral with and disposed thereover the said base, a pair of inclined planes, the said planes being integral with the said base and being transversely opposed to each other, a lever, a boss, the said boss being' integral with the said at base, a fulcrum pin, the said pin being secured to the said boss.' the said lever being rotatably secured to the said boss by the said fulcrum pin, a bracket, the said bracket having a pair of arms,
