ELEVATING AND DEPRESSING SPRINGS. 



boiiins wlic'i Llio hitter ni'O in iictioti. 



To tin's end tlie liiTPtition conrists in ^ipptj- 

 in^ lining spiiiif^.s HI nitcli innnni-r thnt they 

 exert upon tlio beams a innxiniiiin power or 

 strain when Hio latter Jiie above an opcrntive 

 position. 



The spring, opei:itinginaccor«.lance\vith my 

 improved plan, may bo inntio and applied in 

 vari6u.s fonns, winch willreadilysnggeatlhem- 

 selves to tho skilled inccliaiiie without depart 

 inj; fioni tho limits of my invention; 



My springs may be arranged to siisliihi the 

 rthulo or any desired iiorliou of the weight of 

 tho beams w hon tho latter arc rrtised.and they 

 may bo arranged to exerta'slight lifting strai,n 

 v/hen tho bcams'aro'ln action, or, if preferred, 

 arranged to cease (heir lil'tiug strain entirely 

 at ench. timo. 



The essential feature of my invention con- 

 sists ill appIyiiigNi lifting spring or springs in 

 such luaniiDr that they ilo Tiot incrcaao their 

 lifting strain as tho beam i.^de]irossed,tliecon- 

 striictioM preferred being such that the springs 

 exert an increased lifting action as the beams 

 rise from an operative to an inoperative posi 

 tion. 



I am aware that springs liavo been applied 

 iji vftrious ways to assist in lifting the beams 

 in this class of innehines; but in all eases their 

 arringcment was such that they acted with 

 an increased lifting strain as tlio beams were 

 lowered, tiio eoiisefjiience of which airange- 

 mentwas, that the springs eserte<l their grciit- 

 est upward strain when the shoVets were in the 

 ground, at a tihie wlieii it was desirable that the 

 shovels should not bo lilted, and on the other 

 hand exerted but little force when thebeama 

 were elovateil, and wiien it was required that 

 they should bo sustained to relievo the opera- 

 t</r. This old action, it will be seen, is tho rc- 

 vci'so of that which is desired, and the prin- 

 cipal object of n)y invention is to reverse the 

 old mode of action and have the springs act 

 with little or no upward strain when the shov- 

 els are in the ground, but with a strong up 

 ward jiressnre when the beams are lifted. 



1. ill a cultivator, (he combination ot a ver- 

 tically-swinging drag bar or beam and a lift- 

 ing-spring which acts with increasing force or 

 cHect on the beam as the latter rises, and vice 

 versa. 



2. In a wheeleil cultivator, the eombinaliou 

 of a vertically-moving beam and a lifling- 

 spring, substaidially as described, whereby an 

 increasing upward strain is cOnimniiicated to 

 tho beam as tho latter rises. 



3. The combination of a wheeled frame, a 

 vertieally-inoving beam or drag-bar attached 

 thereto, and a lifting-spring, substantially as 

 described, which exerts a greater strain or ef- 

 fect upon Ihe-beam when the latter is elevated 

 than when it is depressed. 



4. The combination of a vcrtically-moviug 

 beam, a liftiug spring, and a shifting or chang- 

 ing bearing or fulcrum, whereby the lifting ac-

 increased as the beam is elevated, substJin-

5. A vcrticallyniovablc beam, in combiua- 

 tiouwith a lifting-spring, coDiiected tlierewiih 

 by a changeable or shifting bearing, substan-

 or etlect of the spriug upon the rising beam is 

 mainlained, noLwilhstanding tho decreasing 

 tension of the spring.

 My invention has relation to that (;lass of 

 devices or attac^limenls which are adapted to 

 exercise a gradually - increasing pull upon a 

 chain secured at one end tliereof, and is there- 

 fore particularly adapted as an attaelmient to 

 walking and riding eiiIti\ators. sulky -rakes.

 provided with slio\il or teeth canying U'amft 

 liinged niionafiatiii' and ailaptnl to be rai.icd 

 or lowered lo biin>; tLe shovels fir teeth, as 

 the case niay be, out of or into o))eratinn or 

 contact with the soil. To rai.se the hinged 

 beams of impIemcntB cf this nature up from 

 tbo ground requires the e.vortion of consider 

 able power, the force or power required for 

 this pnrposo iucieasing in the same ratio as 

 tho distance from the groiuul. Hence tho ob- 

 ject of my invention is to cimstrnet a simple 

 and efficient device or attachment consisting, 

 essentially, of a cam -sheave «liich is turned 

 by the force of a spring and connected to one 

 end of the chain, which, on bein;; wound up 

 by the sheave, raises the beams, so that very 

 little power is required for this operation of 

 raising the beam or beams, as the force^of the 

 spring is increased in exactly the same ratio 

 as that of the resistance to be overcome, as 

 will more fully appear by reference to the fol- 

 lowing description of my improvement as ap- 

 plied to and forming a part of a cultivator. 



1. The combination of the stationary liub or 

 spindle E, sleeve II, provided with the grooved 

 or channeled eccentric catn-sheave I, cliain M.

Our invention rflafes to improvements in 

 wheel-cuUivatorsof tlie straddle-row class J nbd 

 the objects of our improvements are, first, to 

 provhle a two-way joint for connecting the 

 [tlow-beams to the axle, which shall relieve the 

 bolt which retains thepartsof the joint from the 

 strain of the draft of the plows, and which shall 

 have its surfaces of contact on which lateral 

 movement of the jilowsois obtained so con- 

 fitructeil that they will retain a lnL>rieaut, and 

 which are copnected to the plow-beauis in a 

 manner to protect the beams; second, to pro- 

 vide a spriug which shall exert a downward 

 pressure on the plows when in oiieratiou, and 

 an upward or lifting force when the plows are 

 raised above a working position, and which 

 si>riugs are connected with the parts of the 

 joint, aud of tlie axle iu close proximity to the 

 joint, and not with the plow-beam, and houce 

 do not interfere with tho movements of the 

 plow-beams; third, to provide braces wliich do 

 not require adjusting whou tho axle is adjusted 

 to fix the distance between the plows; 'fourth, 

 to provide practical and comparatively cheap 

 njeansof secarioga pivoted tongue loan axle; 

 fifth, to provide means of preventing ueck- 

 drrtft of the tongue; sixth, to provide plow- 

 bundles which maybe adjusted at dilTcrent an- 

 gles to the plow-beams, for tha purpo.so of ad- 

 justing the rear ends of the handles trans 

 versely to the machine; seventh, to provide an 

 attachment of tbo shovels to tho standards, 

 which lu-ovidcs means of removing the bolt by 

 which the parts are attached to tho standard 

 without removing tho shovel-block from the 

 shovel, and which also provides for the nso of 

 a wooden' "break-pin.'"
