To ALL WHOM IT MAY coIvcItRN.`

Be it known that I, L. W. WOLFE, of Jacksonville, Morgan county, State of Illinois', have invented new and useful Improvements in Combined Saw, Boring, and Mortising-Machines; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the lettersof referencemarked thereon.

InV the annexed drawings, making a part of this speciication, A represents a rectangular table, of suitable dimensions, and constructed in a substantial manner, having holes or slots through its top for the saws ff to work through, and a mortise, a, forV the tenon'of the adjustable movable post C to rest in; also a hole or mor# tisc, in which is adjusted a rectangular feed-block, cl,` said block being operated, or raised up and lowered, by means of' the lever e, pivoted to one of the front legs of the table A, one end resting against the bottom of a' frame secured to 'the under side of the block d, and a coiled or pther spring, placed between the .under side of the frame of the table A and the cross-bar of the frame attached to the block d.

Framed into thetop of the' table A are four vertical Vposten-B B, which support the transverse and longitudinal horizontal beams c c, which are screwed to or framed into said posts. l

D represents a crank or driving-wheel, attached to one end of a shaft, which` extends outside of and rests on the longitudinal beams c, said shaft having afbevelled cog-wheel, E, attached to it at the other end.

F represents a faced cog-wheel, attached near one end of the shaft H, resting on the transverse beams c, to ccrrespondwith and mesh into the cog-wheel E. The shaft H is also provided with another plain cog-wheel, G, at its other extremity, said wheel being, in turn, provided with a crank-pin, x.

K represents a saw-frame, constructed inthe ordinary form for lip-and-down saws, with an additional crossbar parallel with and near the top of therfr'ame K, forming agroove, in which the crank-pin a: works, and also provided with arms, I, at right angles with the front of said frame, in which is adjusted a cross-cut saw,f, for the purpose of cutting tenons, shoulders, and other work, as may be required. In the frame K is adjusted a rip-s'aw,j`, for the purpose of ripping up lumber to any desired width or thickness. i

`I, Figure 3, represents a scale, which is adjusted on the top cf the ,table A, parallelA with the side of the sawf, by means of metallic strips, zzz', pivoted to its lower edge at one end, and to the table'at the other end. A third strip, provided with a slot, z, is pivotedjo the scale, as above, and has a screw through the slot z into the table, which allows the movement, laterally, of the scale L to whatever distance from the sawfit is desired, and is there secured by means of the screw in the slote.

By attaching power of any kind to the crank or driving-wheels D, motion' is given to the shaft and Wheel E, and thence, by the meshing of the cog-wheel F with the wheel E, to the shaft H and cog-wheel G, and, by its crank-pin, to the saw-frame and the saws ff. i

C'represents an adjustable or movable post, provided with a shoulder and tenon at its lower end, which J'ts in the mortise in the table A and is fastened down by means of a pin inserted in a hole in the edge of the table, and passing through the tenon ofthe post C. v

On the top of the post C is framed a movable beam, AI, projecting over the said post toward the front, and

provided with holes for the rod P and shank of thechisel N to pass through and'work in.

In front of and in a groove `in the post C is attached the movable chisel or cutter N, by means of `the metallic bands n n. The chisel extends `up through the hole in the beam M, and is there pivoted to a lever or arm, 0, which is itself pivoted at one end to the top and front end of the beam M. At the other end of the lever O is pivoted a rod, P, which passes througha hole in the beam M, and thence to the arm I, and then piv oted, so that, when' the saw-framed operates or Works up and down, the chisel N works simultaneously with it, by means of the arm I raising the rod P, and that the lever O, and that, in turn, vthe chisel N.

When the mortising-attachment is not to be used, by pulling out the stay-pin from the tenon of the post and detaching the rod P from the arm I, theywhole mortising-attachment may be turned on the hinge at the top of post B, up out of the way, until wanted for use again.

R represents a movable beam, hinged to a cross-bar at the top of the two rear posts B B, provided with the ,shoulderspjg into which theends of the shaft S are secured, said shaft having the cog-wheel T near one end,

which meshes with aud takes motion from the cog-wheel E, and the faced or hevelledcog-wheel U, near the lother end.

1' represents a bit and shaft, adjusted vertically in and through the metallic plate u and beam R, provided' with a, head, y', at the top, to keep it from falling through and from the beaurR, and also provided with a shoulder or collar, o, which rests against the plate u, and keeps thebit r from giving way or being pressed up when thel lumber to be bored is pressed against the point ofsaid bit by meansof the lever [e and block d. y

The bit-shaft 1' has attached to it, at a suitable distance from the beam R, ajfaced cog-wheel, J'. which meshes in'and takes motion from the cog-wheel U; v

When the boring-attachment of this machine is used alone, the cra1k-pin ai may beremoved from the wheel G, and thus less power will be required to propel the machine.- l

It is obviousthat either the saws, mortiser, or bring-devces, or all'of them, may be operated either separately or atthe same time, and bythe same power, whenever so required;

When the boring-machine is not required for use, it may be raised up out of the way by meansiofthe hinge by which it is attached to the cross-bur, and there secured by means of an adjustable brace, l, which catches on a. pin on the back side ofthe cross-bar at the' top of the Itwo rear-posts B B. l

' Having thus fullyrdescrbed my invention, what I claim as ne w,zand desire to secure by Letters Patent, is-

The sliding saw-frame K, havipg arms I I, as specificd,'whereby motion is communicated to the mortiser N, y

through the connecting-rod P and lever 0, all constructed and operatingr as specified. z
