Specification of Letters Patent.

Application filed March 12, A1912. Serial 110.683,323.

To all whom 'it may concern Be it known that LXVHLIAM J. HUGHES, a lcitinen of the United States of America, residing' at'Victoria, in the county of Victoria and State of Texas, have invented certain new and useful Innirovements in (lombination-qaws, of which the following is a specification, reference being' had therein to the accompanying drawing.

This invention relates to sawing machines, and the principal object thereof is to provide a machine in which a planer, a shaper or moldcr, a rip ,saw and a cut-oil' saw are operated by a single motor or engine.

In carrying out the objects generally stated above, it will be understood, ofcourse,

that the essential features thereof are sus-u ceptible of changes 'in detail and structural arrangements, one `preferred and practical embodiment ot' the invention being shown in the accompanying drawings, wherein Figure 1 is a side elevation ot' the machine. Fig. 2 is a top plan view of the machine. Fig. 3 is a vertical section through the machine. Fig. i4: is a perspective view of theshaper or melder shaft or mandrel. Fig. 5V is a perspective View of the bracket which holds the planer knives. Fig. G is a perspective View of one ot' the planer knives. Fig. 7 is a perspective view of one of the knives to be used on the Shaper or melder head.

Referring to the accompanying drawings by numerals, it Will be seen that this invention comprises a base having; r side bars 10 and 11, and end bars 12. A -trame is mounted upon the base and comprises the legs 13 and 14, which are connected by cross bars 15 and supports a top or table 16, the top or table being'provided with a longitudinally-extendingslot 17, running' longitudinally with the top plate 1G. A planer mounted in table 18 is provided With an opening 19 so that the planing knives can protrude above the surface of the planing table the desired distance. A motor 20 is mounted upon the frame at the rear end and a shaft 21 is mounted upon the side bars 10 and 11 in bearings 22, the shaft 21 being rotated by a belt 23 passing around the pulley wheels 24 and 25 carried by the shaft 21 and engine shaft 26. A shaft 27 is rotatably bearings 28 carried by the side bars 15 and extends beyond the side of the frame and is positioned beneath the open-` ing 19. A bar 429 having singularly-disposed ends 30 is secured to the outer end of shaft 27 and knives 31 are removably connected with the ends 30 and have their cutting edges protrlulingn above the face of the planint,r table so that when a piece of'timber is moved along the planing' table, the planing knives will cut the lower face. A pulley wheel 32 is mounted upon the inner portion oi the shaft 27 and a large pulley Wheel 33 is mounted upon the shaftl l21 and is connected with the pulley' wheel 32 by means of a belt 3ft, thus cansing` the shaft 27 to be rotated at a great deal faster rate of speed than the shaft 21. A rocking frame has its arms provided with hinges 36 which are secured to the base or side bars 10 and 11, the center of the hinge being placed in line with the center of shaft 21. The upper ends of the arms are connected by a bearingr 37 in which is journaled the shaft 38 having' a rotary saw 39 secured to one end portion beneath the slot 17 so that when the rockingr frame is moved, the saw will be brought. up through the slot to cut work placed upon the plate 1G.` This shaft 38 is driven by a belt 40 passing around the pulleys 41 and 42. A tongue 13 which is braced by means of a bar 44 is positioned between the arms and affords convenient means for connecting the operating mechanism with the frame, and also forms a balance weight to assist in returning the saw to it-s normal position.

The operating` mechanism comprises a lever A15 which is secured to the lower portion of the tongue 113 and is braced by means of the bar t6 which is connected with the,

upper portion of the rockingr frame. The outer portion of the lever is formed into a foot rest fl-7 so that by placing the foot upon the outer portion of the lever, the frame may be rocked to bringr the saw through the slot. When the ioot is removed from the lever, Athe spring 48, which is connected at one end with the rocking frame and at the other end with the base, returns the Saw to its normal position. It' it. is desired to hold the saw in a raised position for any length of time, the latchinglever 1l-9 which is connected with the rocking frame by means ot the chain is moved so that its tooth will engage the rack 51 and thus prevent the spring from returning the saw to its normal position. A Shaft 52 "is jonrnaled in the bearings 53 which are secured to a plate 54,

than the pulley wheel 55 so that the shaft 52v will be rotated very rapidly. Clutch collars 58 are mounted upon the outer portion of the l shaft 52 and a cutting knife 59 is secured between the collars by the nut 60. It is, of course, obvious that the knife 59 may be provided with any desired shape of cutting edo'e. Y A

rom the above description, it-will be seen that the motor drives the shaft 21, the shaft 21 drives the shafts 27 and 38,- and the shaft 27 drives the 'shaft 52.

What I claim is In a sawing machine, a table provided with a slot in its top, a swinging frame, strips carried by saidswinging frame and pivo'tally connected with the side of said table to pivotally mount said swinging frame, a driving shaft journaled upon the sides of said table :beneath said swinging frame, a saw journaled in the upper portion of said swinging frame androtated by y said driving shaft, adepending tongue carried by sald swinging frame, a spring having one end connected with said table and the upper end with said tongue to normally hold sald saw beneath the top of said table,

a foot lever rigidly mounted upon saidl In testimony whereof I hereunto .aiiix myA signature in presence of two witnesses.
