4 Claims.
This invention relates to routers, and an object is to produce a portable router, which is simple in construction, convenient to operate and adjust, provides a clear and complete view of the working operation, and is sturdy and reliable in construction and with a minimum of moving parts.
Further objects and. advantages of the invention will hereinafter appear, and by way of illustration, an embodiment of the invention is shown on the accompanying drawing, in which:
Figure 1 is a perspective view of the router showing it applied to the work; and
Figure 2 is a sectional elevation on the line 2-2 of Figure 1.
An illustrated embodiment of the invention comprises a router having a supporting frame Ill provided with horizontally disposed bar portions I I and I2 between which is disposed a motor support I3. The motor support I3 has a supporting ledge I4 and upwardly extending curved wall I5, the front end I6 being open. An electric motor I I is carried by the support in vertically disposed relation, and has at its lower end a chuck I8 to receive a bit I9. It will be observed that the ledge I I of the motor support is disposed in a plane above the frame bars II and I2, the portion 20 being open to afford an unobstructed View of the bit and work.
The frame bar II extends laterally from the motor support in a horizontal direction and provides a hand hold so that one hand of the operator may grasp this portion during the working operation. Formed integrally with the outer end of the frame bar I I are two depending legs 2I and 22, which are spaced laterally from each other. The lower ends of the legs are curved, as indicated at 23, so that the router can be moved readily over the work-table with a minimum amount of friction.
The frame bar I2 in this instance curves downwardly and outwardly from'the motor support I3 and is supported by a single leg in the form of a screw threaded bolt 24 having an operating knob 25, which provides a hand-hold and enables vertical adjustment of the bit I9 during the operation of the tool. Thus, by turning the wrist in one direction or the other, the bit I9 may be raised or lowered, as required, without stopping the motor and without removing the hands from the tool.
The work, such as an eleotro-type E, is shown clamped between bracket members 26 and 21, adjustable clamping devices 28 on these members holding the work in position. In operation, the router is moved over the supporting surface relatively to the work with the hands in the position indicated by dotted lines on the drawing.
It will be understood that the above described router is moved relatively to the work, the latter being clamped into position on the supporting surface. Inasmuch as the hands of the operator are on each side of the bit at points remote from it and the latter is uncovered and in position to be clearly viewed at all times, the working operation is a natural one performed without strain or a great amount of effort. The depth of the out can be readily controlled during the operation of the machine by slight movement in one direc-- tion or the other of the hand engaging the knob 25. The three-point support for the router affords a satisfactory one, giving adequate balance and freedom from excessive friction.
It is to be understood that changes in details of construction, arrangement and operation may be made without departing from the spirit of the invention, especially as defined in the appended claims.
What we claim as new and desire to secure byLetters Patent is:
1. A portable router comprising a T-shaped frame having a semi-circular recess in the stem of the T, a bitoperating.motor mounted in said recess and a leg projecting in the same direction as the bit from each of the ends of the frame.
2. A portable router comprising a T-shaped frame, a bit-operating motor mounted midway of the stem of the T, the stern providing hand holds on each side of the motor, a leg projecting ,in the same direction as the bit from each of the three ends of the frame and one of said hand holds providing means to adjust the plane of the ends of the legs longitudinally of the bit.
3. A portable router comprising a frame, a bitoperating motor rigidly mounted in the frame, rigid arms extending from the frame beyond the work, and three legs projecting from the ends of the arms in the same direction as the bit and adapted to form a three-point support upon a work-supporting surface.
4 A portable router comprising a frame, a bitoperating motor rigidly mounted in the frame, rigid arms extending from the frame beyond the work, and three legs projecting from the ends of the arms in the same direction as the bit and adapted. to form a three-point support upon a work-supporting surface, one of said legs being screw-threaded through the arm and terminating above the arm in an operating knob.
