ADJUSTABLE TONGUE.

i Speciicationof Letters Patent.- v Patntedl Sept. 1*?, 1912.

Application led NovemberlBO, 1908. Serial No. 465,287.

To aZZlwi-om, it may concern! A lle it known that I, PAUL HANSMANN, a citizen 'of tlieUnited States, residing at.

Long Prairie, inthe county of Todd and lState of -Minnesota, have vinvented certain new and useful Improvements inAdjustfable Tongues, of which the following is a'V 'specification- 'My' invention. relates'to iii-proveniente in adjustable tongues for separators' and 'the' like',v its object being to provide an improved construction of tongue which may be iirmly ,andv claimed..

In the accompanying drawings forming part of this specication F igure' 1 is-,a plan view'of iiiy ,invention and connected' nia- `chine axle, Fig. Q-is a lside elevation of the Same, 'F ig. 3 is'a planview of my invention partly broken away and siiowing thetoi gue in adjusted position, Fig. 4 a-perspect'ive view-.0f a portion of the in v ation, Fig. 5v

'is "a similar view of a supporting bracket .for tlieadjusting mechanism forming part-l of my invention with the adjusting mechanisin removed, and Fig. 61s a section on line of Fig. 5 showing the adjusting mecha.-

nis'ni, I

In the drawingsri represents the trout axle of the machine to which my invention is applied. B represents the tongue having pivotal connection 2 `with thccross bar 3 fl'a'iiiit l0 through which ailji'istalily'extends t iiitzibly connected vas by means 'of links' 4' withthe axle. .'ll innerl end of the tongue vIl eonsists of a'pair ot'V interspaced vplates 5 connected at their 'forwaiil ends to the top and bottom oil the solidportion of thel pivoted tongue'.l The cross 'bar 3 is -torined with a. centratforwar'dly Vextending rigid tongue (S which standsv in alinement'with the ,pivoted tonguewhen-fthey saineis `in normal position. Curvedrbars-f connect. the front end' of the rigid tonguewit'h'tlie'ends of 'the cross bar., said curved bars'forining a trac-k for the pivoted tonguewhen the. sanie isadjiisted.

ln order to`turn sii'cd angle aud'hold it in such position I provide theftollovi'ng mechanism. IIaving pivotal siippprtS in the iiiterspaccd plates 1) for'iiiiiig the end of theirigiil tongiir is the tongue 4 to any del-I a screw rod'll. The screw rod 1l has john' nal support at its ends in a bracket l2l which bracket has central pivotal support 123 between the plates adjacent tov the front end of therigid tongue. I provide one end of the screw rod with a suitable handle lll.

In operation the turning of the handle'ld will rotate the screw rod causing the screw to travel through the nut and turn the tongue upon its pivot to the desired angle with the axle. It will he evident that rotating the shaft in one direction willcause the tongue-B to travel to one side of the Vfixed tongue while the opposite rotating of the shaft will turn the tongue to the epposite side of the fixed tongue. The changing -angles of the fixed and pivotedto'ngues is compensated for in the adjusting mecha-` nism by the pivotal support of the bracket l2 tid of the nut wit-hin vthe bracket.

I claim as my invention: f

v1. In combination with a vehicle, a tongue having'pivotal connection therewith, a relatively short rigid tongue and extending ifo-rwardly inline with said pivoted tongue when the saineis in normal position, a nut pivotally 'supported upon the end of saidrigid tongue and a screw rod carried by sald pivot l tongue and threaded through said nut,

2. In combination with a vehicle, a for- 'Wardly extending tongue having pivotal connection at its inner end therewith, a rigid member'. extending forwardly from said vehicle, an adjusting connection between said rigid member and. said tongue forward of its pivotal support, said adjusting connection` having pivotal support upon said tongue and a positive driving connection with the center of the forward end of said .rigid member, said adjusting mechanism being actuable to, carry said tongue to either side of the pivotal, support of Asaid connection." v

3. In combination with a vehicle and .its

cross bar, a tongue having pivotal connecvtion therewith, a relatively short forwardly" extending tongue rigidly connected with said. cross bar, a nut-carried Aby the' free end --of said rigid tongue, a bracket supported by said pivoted tongue, ascrew rod carried by said bracket and'threaded through said nut -ind :in actuating handle for said rod.

4I'In combination Awith a tongue having 11o ,pivotal support at its inner end, a siuli pole extending firwardly from the supporting ivot of said first mentioned pole, an adjusting connection between the end of said stub pole and the adj acentj. part of said pivoted pole including a screw shaft having a central pivotal support upon said pivoted pole and a screw threaded traveling oonnection with the end of said stub pole allowing said pivoted pole to be adjusted an# gularly past the free end of said stub pole.

5. Inlcombination with a vehicle, aforwardly extending tongue having pivotal support thereon at its inner end, lmeans for angularly adjusting the tongue from a point forward of its pivotal support comprising a screw shaft having central pivotal support upon said tongue at a point forward of its pivot, said shaft having screw threadedvconneotion with a' ixed support alongside its pivotl support upon said tongue.

n combination with a vehicle,'a forwardly extending tongue having pivotal connection therewith at its inner end, a rigid member extending 4forwardly from said vehicle, and an adjusting mechanism connecting'said tongue forward of its pivotal supvport with said rigid member at an unvariable location on said rigid member, and means for operating said adjusting mechanism to carry said tongue to either side of said rigid member.

7; In combination with a vehicle, a forwardly extending tongue having pivotal, connection at its inner end therewith, a rigid member extending forwardly from said vehicle in aiinement with the pivotal support n of said tongue, and an adjusting mechanism entirely and wholly .supported by said tongue at a point forward of its pivot and by said Vrigid member at an unvarying point, said adjusting means constituting a positive adjusting mechanismbetween said member and tongue to allow said tongue to be angularly turned upon'its pivot from side to side of said rigid member.

8. In combination with a vehicle, forwardly extending tongue having pi otal connection at its inner .end therewith, a. rigid `member extending forwardly from said vehicle, and a. screw threaded connection between said tongueforward of its pivotal support and with said rigid tongue at an unvarying point, said screwthreaded connection allowing said tonguey to swing angularly on its pivot tol either side of said rigid member.

In testimony whereof I aiiX my signature in presence of two witnesses. i
