Figure 8 a detail elevation, partly in. section, on an enlarged scale, of the upper portion of the rotatable post or pillar, trackand traveling carriage;

Figure 9 a central longitudinal section of trackway for the carriage;

Figure 10 a bottom plan view of the 'trackway.

In the drawings the numeral 1 designates a frame of suitable formation and material and having a top 2 of wood or other material. The numeral 3 designates an upright pillar or post supported so as to be rotatable, for instance, in a step 4 attached to across-bar or beam 5, or otherwise, and which V the carriage may be may be clamped to its by a split or divided from a cross member of encircling the post and formed with threaded ears 7 into which fits a threaded rod 8 formed with a hand-wheel 9 by which the clamp may be loosened or tightened around the post to permit the post to be rotated and also held to its rotative adjusted position. The upper end of post 3 carries a head 10 which supports upright posts or rods 11 rotative adjustment sleeve 6 projecting the table frame and which pass through a bracket or trackway 12 and on which the trackway is vertically adjustable by means of ascrew 13 threaded into a socket 14; which may have a depending flange 15 with which connects a web 16 on the underside of the trackway, the flange and web giving additional strength to the trackway. The upper end of screw 13 passes through a cross head 1? connecting the two upright rods and is provided with a hand-wheel 18 by which to turn the screw to raise or lower the trackway. The trackway supports a traveling carriage which preferably consists of a rod or bar 19 having side flanges 20 fitting in grooves or guideways 21 formed in the side faces of the trackway, the carriage bar being formed with a longitudinally extending slot 23 through which the screw 13 passes so that the carriage may reciprocate or slide back and forth on its trackway. The traveling carriage supports an electric or other motor 24: and at its other end carries a suitable boxing 25 in which is journaled an arbor 26 provided with a cross-cut saw 27 and a pulley 28 and which may also be provided when desired with a wheel-pulley 29 for reception of a band-saw as hereinafter: described, and a hand-grip 30 is provided for reciprocating the carriage back and forth, andalso a housing or guard 31 may be provided for the cross-cut saw. The cross-cut saw mandrel 26 is driven by a belt 32 running from a pulley 33, which may be a broad faced pulley, on the motor-shaft 34 which will also carry a pulley 35 at its other end. In operating the cross-cut saw reciprocated to the extent desired to suit the work in hand, and by loosening the split clamp collar 6 the post or pillar 3 may be rotated to turn the carriage to present the cross-cut saw to cut at the angle desired, and by means of the threaded engagei and associated parts v.

.the pulley of the motor screw 13 the carriage and saw carried by it may be raised or lowered to bring the carriage and its associated parts within range of the wor to be done.

A rip saw 36 is supported beneath, the work table 2 by a suitable frame which will permit the saw to beraisedand' lowered to and from operative position in relation to the table. 'lhis rip saw tame designated by the numeral may be of the form illustrated in plan in dotted lines, Figure 1, being suitably hinged at 38 to the machine frame and at its free end formed with boxings'39 tor the arbor or shaft 40 of the rip saw carrying the pulley l0 which will be in alinement with pulley 33 ot the motor shaft when the carriage is turned to bring the pulleys into alinement so that the rip saw may be operated by the belt 232 connecting the two miles. 'lhc saw is raised and lowered by suitable means for instance, by a lever 41, which maybe or yolte tormation,

which will have a hinged connection as at 42 with the swinging frame 3"? and be hinged at its other end to a sleeve in .nt with a screw threaded shaft or rod' ll journaled in suitable bearings and provided with a hand wheel so that by turning the slr lit the sleeve l3 ill be fed along the rod so as to lift the rip saw to operative position as shown by d tted lines, Figure 3, and by turning the rod in the opposite direction the rip saw be lowered into inactive position as shown by full lines, Figures 3 and. 5.

A band saw 47 will pass around the wheel pulley. 29 and around another wheel pulley 49 mounted on a shaft 50 journaledin a boxing 51 supported by a bracket 52 supported from the machine frame and in a "boxing 53 bolted to a. suitable part of the frame and provided with a pulley 5 L from which a drive belt 55 will pass to and around shaft so as to be driven from the motor. The band saw passes 'through an opening 56 in the work table which may be covered by a slide plate 57' formed with laterally extending slots 58 connections described. It the piece o'l work to straddle the saw band and which will be free to slide back and forth in the recess 59 in which the plate seats in the ad ustment of the band saw by movement of the traveling screw i3. When the band saw is not in use it is removed and the opening 56 covered by plate tlOiwhich will replace the slot-ted platei5?- and beproperly secured in place by screws 61 so as to afford a smooth unbroken From the fore-.

the position indicated in Figure l to that indicated in Figures 2 and 3, the band saw applied to its wheel pulleys-and a drive belt run from pulley 35 of the motor to pulley 54; of the shaft of the lower band wheel pul- .ley 49, and thus the band saw is driven from boxings (S-l" attached to the machine frame and provided with a pulley 65 from which belt 56 may extend to the pulley 35 on the motor shaft so as to be driven therefrom, the shaft tl l 'being also provided with a pulley 67 tromwhich a belt 68 passes to and around a pulley 69 on a countershalt 70'which carries the abrading belt band-pulley 64, and thus the abrading belt is driven fromthe motor carried by the traveling carriage.

The countershaft is journaled in suitable bearings supported from the machine't'raine asindicated and carries also a pulley 71 from which a crossed belt 72 passes to a pulley 73 on a shaper-tool 74c supported so to be moved vertically through the work table by a lever 75 tulcrumed-on a partof the frame and held to its adjustment :by

the lever engaging with teeth 76 ona bracket 1 .7 supported from the machine frame as shown in Fi ure 7 of the. drawin The counter shalt 40 carries also pulley 7 8 from which a belt '1' 9 passes to a pulley 80 on a tool holder 81 supported by a bracket 82 attached to the side otthe machine frame.

In front of the tool holder is a table 83' slidably supported on rods 84 encircled by springs'85 to restore the table to normal position when moved therefrom. If a piece of work is to be'boreda boring bit or tool 86 will be coupled tothe tool holder and the work placed on the table and the table -moved byv hand to bring'the work against the boring tool which'will be'rotated by the I belt connection between the pulleys 78. and 80., the power belng transmitted from the motor on'the traveling carriage by the belt is to be mortised the borin tool is-encircled and having its teethiengagingwith teeth. 90

.onthe worktable will be connected by a chain 91 with a foot pedal 92 so thatwhen the work is placed on the table and the foot pedal depressed the work will be pressed against the mortising'tool to'form themortise, and the springs 85 being placed under compression will return the table to normal position when pressure is 1 relieved. 'When the boring toolis used the j-mortising tool is removedfrom the boring bit-without disconnecting the belt which transm1ts-power from the motor. It will thus be observed that when desired the boring tool may be operated from the motor carried by the carriage, and at other times a mortising tool may be used.

A jointer 93 is positioned alongside the machine and the shaft 94 of its tool 95 is provided with a. pulley 96 which will be in alinement with the pulley 33 of the motor shaft when the carriage is turned to the position shown in Figure 1 so that the pulleys may be connected by a belt 97 for driving the jointer tool from the motor.

From the foregoing description it will appear that the machine is so constructed that it may perform the functions of a cross-cut saw a rip saw, a band saw, a sand or abrading material belt for finishing the surface of the work, a shaper, a boring or mortising machine, and a jointer by merely changing the position of the carriage supporting the motor so as to bring the pulley carrying shaft of the motor into position for connecting its shaft with the pulleys through which power is transmitted from the motor to the particular part of the machine to be operated. The change from one position to another and the placing or removal of the transmission belts is quickly and conveniently effected because of the relative arrangements of the various parts.

The preferred details of each most efficient action of the several parts are illustrated with some particularity but changes may be made therein and essential features retained.
