PORTABLE AND CONVERTIBLE MACHINE.
Application filed April 28, 1826. Serial No. 104,103.
My invention relates to a portable and convertible machine for working wood or other materials. I
The object of my invention is to provide a 5 machine having a motor and a driven mandrel attached thereto, the mandrel to receive jointer and shaper heads, saws, grinders, buffers, sanders and drill jaws.
A further object of my invention is to 1 provide a machine with grips by which means it is moved along while performing its work, or to hold the machine in a sta tionary operative position.
A still further object of my invention 1s 15 to provide a machine that can be applied in different positions and one that can be attached to a work bench stationarily functioning for various purposes hereinafter set forth.
A still further object of my invention is to provide an electric motor driven machine with the switch positioned convenient to the grip for instant and emergency control.

side of the frame of the supporting frame to the machine and its means of connection therewith.
Referring to the drawings in detail, 1 is a bed in which is pivotally connected a frame 2, and tensioned thereinby means of a win nut 3. As a means for adjusting a vertica position of the bed 4 of the frame I have provided a turn buckle 5 threadedly engagmg on rods 6 and 6'. The rod 6' is pivotally connected to an eye 7 which is integral with a re-inforcement 8 on the end of the bed. The rod 6 engages in an eye 9 which is ri idly attached to the vertical member 10 o the frame. On the top of said frame member is a grip 11 transversely positioned thereto. And on the opposite end of the bed is a grip 12. The said grips function as elements by which the machlne may be moved manually for'purposes hereinafter described. Adjacent to the lower portion of the grip 12 is a band 13 functioning as a yoke and having in the ends thereof elongated slots 14 to slidably engage on the ends of a lug 15; said lug having an apertu, c 16 longitudinally passing therethrougli: and in which engages a rod 17 having wing nuts 18 threadedly engaging on each end thereof as securing means for the desired slant of the bed, it being understood that the yoke may be detached for a vertical position of the bed as shown in Fig. 5.
Rigidly attached to the bed intermediate the grip and the vertical frame is an electric motor 19 having a cable connected thereto, but not shown in the drawings. The switch 20 controlling the current is shown positioned on the upper part of the grip 12 as a convenient position to operate with the thumb while conveying the machine by the grip. v
On the shaft of the motor is rigidly attached a sheave pulley 21 adapted to receive a V-shaped belt 22 which engages with a like pulley 23 rigidly attached to an arbor 24; said arbor being trunnioned in a bearing 25 transversely positioned on the under bed 4. The opposite end of the arbor being threaded is adapted to receive a circle-saw 26 or other tools such as a jointer head, sanding drum, a drill bit jaw, buffers, dado heads, emery wheels or other tools rotatably operated, and being actuated by the motor heretofore described.
The sheaves 21 and 23 are interchange able as a speed varying means for the arbor, 1 g
other sheaves of different diameter and ratio relative to each other may be attached as lie within the magnitude of the machine structure.
It will be understood that the turn buckle- 5 and the yoke member 13 co-act for an accurate and rigid adjustment of the vertical movement of the mandrel carrying the tool elements heretofore defined. The bed 1 is re-enforced by side flanges A and re-inforcements 8 connecting both ends thereof and integral therewith and also the bed. Axially positioned in both re-inforcements are apertures B adapted to receive rods 27 hereinafter described.
A lurality of screw holes 28 are positioned in the bed as means for fastening the bed firmly to a supporting means such as a work bench top or the like. Another means of supporting the bed is by rods 27 slidably engaging through the apertures B for latera-l movement of the bed. When properly positioned I have provided set screws 29 to bind the bed firmly to the rods. As a supporting and fastening means for said rods I have provided angle irons 30 having lugs 31 on each end thereof in which are apertures to receive the ends of the rods which are bound firmly therein by means of set screws 32. Through the opposite right angle leg of the angle iron are a plurality of screw holes 33 by which means the said irons may be fastened firmly to the under side of a bench top or other means of support. In the event of using the machine as a rip saw spacing may be made for the width of strips being sawed by shifting the machine on 'the rods heretofore described. Other spacing means may be attached to the upper side of the top co-operating with the first said spacing means. On the side of the bed adjacent the tool attaching end of the arbor is an upwardly extending ear 34 having an arcuated slot 35 therein as means for attaching a rest 36 when a grinding element is attached to the mandrel. The relative position of the grinding device and rest are shown in Fig. 5 and when the bed of the frame is vertically positioned as shown in said figure it is rigidly fastened by means of a bolt 37 positioned in an aperture 38 passing through the front grip eliminating the danger of a rear rock of the frame while grinding.
On the under side of the bed is a channel 39 longitudinally and centrally positioned therein functioning as a guide receiving a member 40 as shown in Figs. 11 and 12 for the purpose hereinafter described.
The member 40 has blocks 41 and 41 rigidly attached to each end thereof and transversely positioned thereto. The block 41 has a dowel 42 centrally positioned therein and adapted to engage in an aperture 43 in the bench top as shown in Fig. 11. The opposite end of the member being free to swing on its pivot point is means for guiding the machine to any desiredangle for cutting (lados, kerfs and the like as shown by the dotted lines G in Fig. 12; it being understood that the dotted lines may represent a window jamb and placed at right angles to a bench top. Then by swinging the member 40 as heretofore described the dado C is cut angling across the jamb as shown at C. When the machine is inverted and rigidly supported by the bench top as shown in Fig. 6 functioning as a rip saw the blade of the saw protruding upward through the bench top is the cutting portion of the saw and is adjustable vertically by means of the turn buckle and yoke heretofore described. The said adjusting means functions for other tools placed on the arbor. Note an opening 44 is transversely positioned in the bed to receive the arbor bearing 25 so that tools of small diameter'may extend above the bed when the machine is inverted as shown in Fig. 6. The frame supporting the motor and arbor may be removed from the bed functioning as a boring apparatus as shown in Fig. 8 and other purposes may be adopted when so removed.
Such modifications may be employed as lie within the scope of the appended claims.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a portable and convertible machine, a right angular frame and a bed pivotally connected, an electric motor and a mandrel carried by the frame, the frame adapted to rock so that either side of the right angle will position parallel with the bed, and means for attaching the frame to the bed rigidly when rocked either way.
2. In a portable and convertible machine, a bed having flanges laterally extending from the sides, a roll at both ends thereof integral with the flanges and the 'bed, a right angle frame pivotally carried to the flanges so that either leg thereof will engage between its respective roll on the bed and its pivot point, a turn buckle actuating means attached to one roll and one leg of the right angle frame for rocking said frame to a desired angle, a yoke on the opposite leg of the frame, slots in the ends of the yoke to engage on the ends of a rod, wing nuts to bind the yoke at the desired position, a grip on the outer ends of the legs of the frame, a motor and a mandrel carried by the frame, an electric cable for the motor, a switch to make and break the circuit.
