Toall whom, t may concern,.-

Be it known that I, REUBEN- .Toi-1N Liana,

The object of this invention is to provideV improved means for reversing a tool-carrying device or devices for carrying Work to be op-v erated upon by tools; and with this and other objects in View the invention consists in a device or apparatus of vthe class specified constructed as hereinafter' described and claimed.

In the drawings forming partof this specication, in which the separate parts of myimprovement are designated by the same reference characters in Aeach of the views, Figure lis a sectional side elevation of a machine or apparatus embodying my invention; Fig. 2, a plan view thereof; Fig. 3, a'bottom plan View; Fig. 4, a section on the line 4 4 of Fig. l, and Fig. 5 a side elevation of a right and left threaded shaft which I employ.

In the practice of my invention, asfshown in the draWings,-I provide any suitable frame or support comprising upright end portions a and a base-plate a2, said end portions and said base-plate being securely bolted together, as shown at a4, and in the top of the end portions ct is secured a rod b, which is provided adjacent to each endI thereof or at a predetermined distance from and on the opposite sides of the center thereof with transverse stops c.

Mounted centrally of the frame and above the base-plate a2 isa shaft d, provided at one end with a loose pulley e and a driving-pulleyf, and said'shafty CZ is provided with a right-hand thread of asize and pitch required, and on and through this right-hand thread is cut a left-hand thread of the same pitch and size if the reciprocating motionshare to be equal, but of a different pitch and size if the reciprocating motions are to be unequal.

Mounted on the shaft d and movable longitudinally thereon is a reciprocating frame or member g, the bottom of which is provided With a member g2, Which moves in a Vslot gsin the base-p1ate a2, this construction forming a guide for the frame or member g.

The frame or member gis designed to carry tools of any kind or class or to carry mate-v rial to be worked upon by tools of any kind or class, and said frameror member is provided With two vertically-arranged chambers g4, inthe bottom of each of Which is mounted a half-nut g5, and the corresponding halves of the nuts g5 are placed on the shaft el and are eachprovided with a spindle Q6, and these spindles g6 pass upwardly through the top g7 of lthe frame or member g and are provided in their upper endsvvith a vertically-arranged slot g8, and the top g7 of the frame or meme ber g is provided centrally with an upright gg, inl which is pivoted at g10 a lever h, provided at its opposite ends with a head h2, and the headsh2 fit in and Work in the slots gs of the spindle Q6.

' The lever his provided With a supplemental upright lever h3, Vwhich is providedl with a central enlargement h4, having a verticallyarranged slot or opening h5, through which the rod b passes, and said supplemental lever h3 is provided at its upper end with aweight h6. The separate parts of the nut g5 in one of the chambers g4 are provided With a left` hand thread, which corresponds With the lefthand thread on the shaft d, and the separate parts of the nut g5 in the other chamber g4 are provided with a right-h and thread, which corresponds vvith the right-hand thread on the shaftvcl, and it Will be understood that the' bottom parts of said nuts are always in engagement with the shaft d, and the movement of the frame or member g, which constitutes the reciprocating member, will depend upon the position of the lever 71, and the supplemental lever h3 and on which the upper halves of said nut are in connection With said shaft.

If the parts be in the position shovvn'inFig. i

l and the shaft d be turned, the reciprocating frame or member g Will be moved to the left until the supplemental lever h3 strikes the stop c at the left end of the rod b, When said supplemental lever will be reversed and the upper half of the nut g5 in the left-hand chamber g4 will be raised from the shaft d and the upper halt` of the nut g5 in the righthand chamber g4 Will be depressed into said shaft. This movement of the parts will at IOO once reverse the movement of the frame or member g,and saidframe or member will move to the right until the `supplemental lever h3 strikes the stop c near the right-hand end of the rod b. It will therefore be seen that'the frame or member g will be given a constantlyreciprocating motion or movement back and forth in opposite directions on the shaft CZ as long as said shaft is turned by the pulleyf, and this will be true no matter in what direction the said shaft is turned.

Having thus fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a machine of the class described, a frame, a rotatable shaft mounted therein and provided With reverse threads, a reciprocating member mounted on said shaft and provided with two nuts through which the shaft passes,

the said nuts being divided horizontally into two separated parts or halves, one of said parts or halves being provided with a lefthand and the other with a right-hand thread and means for alternately raising and lowering the upper halves of said nuts as the reciprocating member is operated, said reciprocating member being adapted to be oper- REUBEN JOHN LINES.
