McClintock, Refugio, Tex. Application February 29, 1936, Serial No. 66,444 4 Claims. (Cl. 192--139) This invention relates to gin- breast lifting de vices, and has for one of its objects the produc nism A, which power lift mechanism comprises .a frame H upon'which frame is the main drive ` tion of a power device for automatically lifting the breast of a cotton gin through the operation 5 of a trigger mechanism, whereby the breast may be lifted out of a ginning position should the gin become choked or otherwise fail to properly function. A further object of this invention is the produc 10 tion of a simple and eflicient power mechanism for lifting the breast of a cotton gin and also automatically applying a brake to the power mechanism and re-setting the same, whereby the power mechanism will again be ina position to l5 lift the breast should the necessity for such action .again arise. 1 1‘ ` Another object of this invention is the produc tion of a simple and efficient mechanism- for lifting the breast of a cotton gin which is so constituted as to operate'withïfacility in con junction with the conventional gin structure now so commonly in use. ‘ ' Other objects and advantages of the present invention will appear throughout the following specification and claims. 25 In the drawings: -‘ Y ‘ ' > ' a ' shown in Figure 1; K ` l Figure 3 is a front end elevation of the power device, the weight-supporting lever being shown in section and a portion of the gin being also shown; 35 - Figure 4 is a transverse section taken on line 4-4 of Figure 2; A ~ Figure 5 is a perspective View of a portion of the trigger-supporting frame and trigger mecha nism; ' Figure 6 is a section taken on line Figure 3; ' Figure ’7 is a top plan view, of the forward end of the power mechanism, the parts being shown in their operating position. 45 By referring to the drawings, it will be seen that G designates the- gin which may be of the conventional type having a conventional gin breast B which is pivotally mounted in the con ventional manner and is actuated by a pivot cam 50 lift L also of the conventional type. This cam lift L is actuated by an operating rod lil which extends rearwardly of the gin G, as shown clearly in Figure l; actuated by a drive belt I4 from a power line shaft. This drive shaft i2 carries a second driv ing pulley i5 over which a power belt l@ passes., the power belt I6 extending forwardly and longi tudinally of the frame A and passing around an idle pulley Il supported or carried by the trans mission shaft !3. A fixed or drive pulley I9 is carried by the transmission shaft I8 and is se cured thereto» in the conventional manner, the drive pulley i9 being arranged in close proximity and to one side of the idle pulley I1. ` A brake drum 2Q is also carried by and secured to the. transmission shaft i8 and may be located to one side of the fixed pulley i9. A brake band> 2i is secured at one end to the supporting rod 22 which supporting rod 22 is in turn supported by the upstanding armsy 23 carried by the frame El. 20 The opposite end of the brake band 2l is se cured to the inner end of the brake lever 25, which brake lever is pivotally-se'cured between the bi furcated end 26 of the standard 2l mounted‘on the front end of the frame l l. A suitable counter 25 balance weight 28 is carried by the outer end of ~ Figure l is a side elevation of the power device shown in association >with a cotton gin; Figure 2 is a top plan View of the power device 30 shaft l2 carrying a drive pulley i3 which is , For the purpose of lifting thegin breast-B, vI 55 employ a specially constructed'fpower lift -mecha the brake lever 25. The frame Il carries near its forward end in advance of the transmission shaft i8 an auxiliary transmission shaft 2Q which extends substantially » 30 parallel to the transmission shaft i8 .and is journaled upon the journals Sil carried by the frame ll. This auxiliary transmission shaft 29 carries a sprocket wheel 3l over which passes. a sprocket chain 32, the sprocket chain 32 passing i 35 also over the sprocket WheelSS carried by the transmission shaft i6 wherebyv rotary motion may be imparted from the transmission shaft I8 to theA auxiliary shaft 29. The auxiliary transmis sion shaft 29 carries a gear 34 at its outer end> 40 which meshes with an enlarged gear 35, which gear 35 -is carried by the actuating shaft 35 which is journaled at one end, as -`at 31, to the frame ll, and at its opposite end to a suitablel supporting journal 6B. This actuating shaft 36 45 carries `an actuating arm 39 which in turn con nects to the operating rod l0, which rod lil is connected to the cam lifting lever L. A hand lever ¿ill is also carried by the actuating shaft 35 to permit the manual operation of the shaft 36 should it be desired at any time. A chain of other suitable iiexible element 4I Vis connected to a connecting hook 42 carried by the enlarged gear wheel 35 and this gear wheel also carries aplur'ality of connecting hooks 43 which, 55 2 Y ' 2,090,543 act as guides or cradles for the chain as the gear ' this rotation of the wheel 35 continues, the lug 64 operates in a clockwise direction. VThis chain` 4| will engage'the lingerv 63> and the ñnger B2'to the dotted line position shown in Figure 2, where is connected at its rear end to a lever 44, which' lever 44 is carried by an upstanding rod 45-note upon the'weighted lever 25 will cause the Ybrake band 2|> to be applied, slowing down the rotation of the shaft I8 andthe lever 44 through the pull` of the chain 4I will pull the arm 50 Yand triggerr Figure ö-the upstanding rodV45 being journaled Y at its respective ends'upon theV arms46 of the up rightv frame 41. ThisV upright shaft 45 carries a belt shifting armr48 near its lower end which en 53 to a set position suchas is shown inY Figure’V 5, resetting the Vvarious' parts whereby they mayV again actuate uponthepull of the'cord 54 to re gages the belt shifting finger 49, the belt shifting finger 49 also engaging or straddling the belt I6 for the purpose of shifting the belt I6 from the idleV pulley |'| toV thedriving or ñxed pulleyrlß. lease the trigger. „ ~ . ’ .
