No. llhll? 1 Claims. (@Cl. 144 l} This invention relates to carpenter combination power tools.

An object of the invention is to combine several motordriven tools such as a circular saw, a planer, and a belt sander, in a single handy unit with a single motor arranged to drive any one of the several tools at the option of the operator.

Another object is to provide a combination tool in which the operator may change from one tool to another by opening the handle like the lid of a box, swinging it about the frame of the tool, and closing it again.

Another object is to provide a combination motordriven hand tool that is small, light in weight, portable, attractive in appearance, simple to operate, and of low manufacturing cost.

These and other objects will be readily understood from the following specification taken in connection with the drawings in which:

FIG. 1 is a perspective view of the invention;

FIG. 2 is a side view taken in the direction of arrow 2 of FIG. 1;

FIG. 3 is an end view with the belt sander in position for use;

FIG. 4 is a side view, taken in the direction of arrow 4 of FIG. 3, showing the hinged handle plate or cover closed in solid lines and open in dotted lines;

FIG. 5 is an end view partly in section taken on the line 5-5 of FIG. 4;

FiG. 6 is an end view similar to H6. 3 but with the handle plate or cover open and being swung into position for using the circular saw as indicated by arrow 3;

FIG. 7 is an end view of the other end of KG. 6 with end plate removed;

PK}. 8 is an end view similar to FIG. 3 but with the planer in position for use;

FIG. 9 is an end view partly in section taken on the line 5-5 of FIG. 4 and showing the gearing arrangement for driving the planer;

FIG. 10 is a partial sectional view taken on the line iii-filo of FIG. 4 showing the hinged plate cover in closed position;

FIG. 11 is an end view of the invention with the ci-rcular saw in position for use;

FIG. 12 is an end view partly in section taken on the line 5-5 of FIG. 4 and showing the gearing arrangement for driving the circular saw; and

FIG. 13 is a side view partly in section taken on the line 13-13 of FIG. 12 showing how the motor assembly is rotatably mounted in the end plate of the triangular frame. 4

Referring to the drawings, triangular frame 14 has three

peripheral faces

21, 22, and 23. Circular saw 31, planer 32, and belt sander 33 are operably mounted in frame 314 in positions corresponding to the three

faces

21, 22, and 23 respectively. Drive gears 41, 42, and 4-3 are mounted in frame 14 and are operably connected in any convenient manner to circular saw 31, planer 32, and belt sander 33 respectively.

Motor 15 is axially and rotatably mounted in end plate 45 of triangular frame 14 and is provided with drive pinion lld. An assembly including handle 17, handle plate 18, and side plate 1.9 is pivotally mounted on motor 15. Handle plate 18 is hinged to side plate 19 by hinge 2t and can swing between open and closed positions like the lid of a box. See FIG. 4 and FLGS. 5, 6, 7, 8

Lock pin 28 may be turned by thumb nut 2% to lock the selector assembly in any one of three positions corresponding to

faces

21, 22, and 23 respectively Handle 17 may include a switch (not shown) on extension cord 25 which connects motor 15 with an outside source of power.

iidler gear 4i) is operably mounted on motor housing 15 and is always in mesh with and driven by drive pinion 16. As shown in FIGS. 1-5 inclusive, the assembly is in position for using belt sander 33, idler gear 4-0 being in mesh with belt sander drive gear 43. Handle plate 18 is locked in closed position corresponding thereto by lock pin 28.

To change from belt sander to planer, thumb nut 2-9 may be turned to release lock pin 28; then handle plate 18 may be swung on hinge id to the open position shown by dotted lines in H6. 4. FIGS. 6 and 7 show axial views of the invention with handle plate 18 open and the assembly being swung from the belt sander position of FIGS. 1-5 to the planer position whereupon handle plate 18 will be closed and locked as shown in FIGS. 8 and 9; then idler gear 40 will be in mesh with planer drive gear 42.

in similar fashion handle plate 18 may be opened again and the selector assembly swung another then closed and reloclccd in the circular saw position shown in F163. 11 and 12 whereupon idler gear 40 will be in mesh with circular saw drive gear 41.

Operation of the several tools is well-known. It is clear that the operator may readily select any one of the three tools and that only one of them can be connected to motor 15 by idler gear 40 at any one time.

Having thus described the invention and its operation it is obvious that the objects as stated have been attained in a practical manner. While a single embodiment of the invention has been shown and described, it is understood that changes may be made in the number and kind of motor-driven tools, and in the construction and arrangement of various parts of the invention without departing from its spirit or scope as set forth in the following claims.

1 claim:

1. A carpenter combination power-driven hand tool comprising a triangular frame having three peripheral faces; a belt sander, a planer, and a circular saw operably mounted in said frame in positions corresponding to said three faces respectively; a drive gear for each of the three tools; a motor coaxially and rotatably mounted in said frame; and means for selecting and operably connecting said motor with any one of the three tools, said means including an assembly rotatable with, and about the axis of, said motor, and an idler gear mounted onsaid assembly and operably connecting said motor to any selected one of said three drive gears.

2. A carpenter combination power-driven hand tool comprising a triangular frame having three peripheral faces; a belt sander, a planer, and a circular saw operably mounted in said frame in positions corresponding to said three faces respectively; a drive gear for each of the three tools; a motor coaxially and rotatably mounted in said frame; and means for selecting and operably connecting said motor with any one of the three tools, said means including an assembly rotatable with, and about the axis of, said motor, an idler gear mounted on said assembly and operably connecting said motor to any selected one of said three drive gears, and a handle plate hinged to said assembly like the lid of a box, said assembly being rotatable about the axis of said frame when said handle plate is open and being locked in position relative to the one of said three faces corresponding to the tool selected when the handle plate is closed.
