Application led October 8, 1923.. Serial No. 506,439.

To @ZZ u: 710m it may] m-ern n Be it known that l. lemmi-2r ZinseniiAorN, a citizen ofthe TTuited States. re siding' at liesueur 5Center. in the count;Y ot Le Sueur and State .ot lilinnesota, have invented a new and useful' FlouLever, ot which the Jfollowing is a specification.

This invention aims to provide simple means whereby a lover, 'carrying a latch adapted to cooperate with a sefnnent,v mav be operated from remote point, the structure being ot peculiar utilita;7 in operating* plow levers troni the tractor :which draws the plow. p n y lt is within the province oil the disclosure to improve'generallv and to enhance the utility ofdevices ot that Vtvpe to which the invention appertains.

With the aboveand other objects in view,

which will appear as the description proceeds, the invention resides kin the combina- `tion and arrangement ot parts and inthe details of construction hereinafter described and claimed, it being` understood that, withinthe scope oic what is claimed, changes in the precise embodiment ofthe invention shown.y can be made withoutdeparting from the spirit of the invention.`

In `the accompanying drawings Figure l shows in side elevation, a device constructed in accordance with the invention; yFigui-e2 is a top plan` wherein parts arebrolzen away; Figure iis a section taken p on theline 3 3 o l Figure 2, parts ren'iainiuuP in elevation; Figure vtjis a tragmental de tail showing the, connection between said parts in Figure 3; Figure `5 a tragmental elevation depicting;` the opposite side ot' the lever and segment from that shown in .Fingure l; FigureV 6 is a fragmental longitudinal section showingaportion of the actuating shaft;A Figure Tis a section on theline 7`-7 ot Figure 2; y y

The numeral l denotes a segment whereon a lever 2 is tulcrumed, the lever being adapted, as indicated at 62, "for connection with the part which the lever operates, the lever being fulcrumed at 8 on the segment, the

fulcrum element being in the 'form ot' a bolt, it desired. An offset tongue 4l. is secured at 5 to one side of the lever 2'and overlaps the curved portion of the segment l, The tongue 4 and the lever 2 are supplied with alined slots 6. A tubular guide 7 is secured to that side of .the `lever 2 which is remote from the tongue ll. A latch 8 is mounted `interengagingt radial teeth lll.

,tor right line sliding' movement in the `guide T and includes 'a transverse finger S) movable in the slots t3 and adapted to cooperate with the teeth l0 oit the segment l. under the action ot' a retractile spring` ll, connected by attaching elements l2 to the linger and to the tulcrum bolt 3. 1

\ A shaft le which may he in the ytorni o! a bolt. is mounted in the upper end ot the lever 2. A. clutch member l5 surrounds the shaft lll and is fixed on the upper 'end ot the lever'Z. A movable clutch member i6 is journaled on the sha'lt 14 and has a recess i7 deiining a flange 18, the flange i8 and the fixed clutch member l5 being supplied with l p A compres? sion Spring Q0 surrounds a portion oft .the shaft 14e and abuts at one end against the movable clutch member 16, the spring` abutting at its other end against a nut Qlron the shaft/,the shaft having; a head 22 engaging the lever 2. The spring` 2O serves toimaintain the teeth 19 ot the clutch men'ifb'ers 1G and l5 detachably interen'gaged. The clutch end 27 which is squared as at 28 and threaded as at 29. l A crank `arm BO is helden the squared portion 28 'ot' the member 24 by 'a nut 3l threaded on the i'art L9`ot' the nii-#riber 241. '.lhe crank` arm 30. includes au extension 3Q dispo-sed parallel to the shalt member 245 and parallel to `the bearing 2 3,

4,the extension 32 having a depending ear 25 .which isoutwardlv oilset as shown at Sel. A.

pivot element 35, such` as aj bolt, is carried bv the ear 83 andv is disposed co-azrially'with the shaftll, the pivot element'carrvingsw perposed nuts 36. A linlri' extends longitudinally ot the lever 2 yand is 'supplied at one end with a hook 38 lengaged with the latch 8; rt its opposite end, thev linli 37 is supplied with an enlarged eye 39, loosely mounted on the pivot element 35 and located between the ear 38 and the superposed nuts 36 on the pivot element.

The numeral l0 denotes a socket consti tuting a part of the actuating shaft herein-4 before mentioned. rEhe squared portion 25 oit the member` 24toit the actuating shalt is i eldagainst rotation in the socket All), but is longitudinally slidable therein. its outer end, the socletO terminates in a loopshaped handle il There are seats in the squared portion oi' the member 2l, and in any of the seats l2, the transverseend t3 of' a. latch lll may be received, the latch being` -pivoted at f5 on wings i6 carried by the socket 4th fr compressing spring il? is interposed between the latch is 'and the socket il@ and tends toV maintain the end i3 or" ythe `latch engaged` with any one of kthe seats ll2 inthe member 25. The latch lll is pivoted at i8 to one arm orp a bell cranlr lever` 49 inlcruined at 50 on a standard 5l carried by the socket 40. The numeral 52 marks an oper-y ating rod, pivoted at its inner end, f s shown at 53, to the bell cranl: lever fl-Q. the operating rod being slidable in a guide 541 on the socket 4:0 and carrying a transversegrip 55 disposed parallel to the handle il on the socket 40.

`By means ot the handle ell, rotation may beimparted to the actuating` shaft including the socket l0 and the shaft member 2 5, the portion 24 of the said shaft member .ro-

`tating in the bearing 23. F rom the `meniber 24, a swinging movement is imparted to the cranlr arm 30, the extension 32 there of, and the linl; Swithdrawing ythe latch 8 out of engagement with the teeth 10 ot the segment l, the spring 1l being extended. After the latch has been disengaged'ifrom the teeth l() ot the segment l, the lever 2 may be swung on its tulcrum 3, through the instrumentality of the actuating adjusted position, the handle il may ybe released, whereupon the finger 9 of the latch 8 will cooperate with and engage the teeth' l0 ofthe segment l, under the action or the spring 1 1, the part l24 rotating in the bearing 23 to permit such an operation.

The actuating shaft 25-40 `may bev disposed at any angle with respect to the lever 2, by simply swinging ythe said actuatingl l c, represented by the shaft lli, the spring 20 yielding tov permit a shitting of the `clutch Ymember 16 shaft on its pivotal mounting with respect to the clutch member 15, the

teethql) serving to hold the actuating shaft l0-25 in any position to which it may have been adjusted, angularly with respect to the lever 2.

The handley 41 on the actuating shalt` 40h-25, and the transverse grip 55 on the Voperating rod 52'may be grasped simultaneously, the operatingrod being drawn outv shalt `25-40. When the lever 25 has assumed an Wei-aiy, al@ een Crank i9 being aired, the spring 49 being compressechthe latch lll being tilted on its fulcrum 45, and the part i3 or" the latch being withdrawn from any lever lulcrumed for swinging movement, a

latch carried by said lever, an actuating shaift disposed at an angle to the lever and comprising slidably connected parts which are relatively movable to vary the length of the shaft, means for holding said 1parts in :adjusted position with respecty to each. other.
