TURNTABLE ATTACHMENT.

Application filed July 1,

To all whom it may concern:

Be it known that we, JOHN M.VANGLE and WILL R. LYNN, citizens of the United States, residing at Allen, in the county of Collin and State. of Texas, have invented new and useful Improvements in Turntable Attachments, of which the following is a specification. j 1

This invention; relates to cotton gin presses, and has for its primary object, the provision of means for revolving the turn table of the press by motive power, and automatically stopping the table at each half revolution.

. ,More specifically stated, the invention embodies amongst other features, a belt driven shaft, supporting a fixed pulley and an idle pulley, the. belt being automatically shifted from one pulley to the other incident to the operation of the means which automatically stops the turn table, the latter being released and the belt again shifted .by means of a manually operable element.

The nature and: advantages of the inven-' tion will be better understood when the following detailed description is read in connection with the accompanying drawings the invention residing in the construction, combination, and arrangement of parts as claimed, a a

In' the; drawings forming part of this ap; pl-ication, like numerals of reference indi cate similar parts in the several'views, and wherein:: Figure 1 is a top plan view'of our improved turn table. V

Referring to the drawings in detail, 1O indicates the platform of a cotton gin press, which'platform is provided with an opening in which the turn table 11 operates. 1 Thetable 11 is rotated by a vertical shaft 12'which is journaled in suitable bearings 13, and this shaft supports a gear wheel 15, which meshes with a worm gear 16 as shown. The latter mentioned gear is keyed to one end of a shaft 17, the latter being arranged at-a right angle to the shaft12 and secured, to theoppo'si'te end of the shaft 17 and fixed thereto is a belt pulley 18. Also journaled to the shaft 17 and arranged in 1922. Serial No. 572,345.

It is of course understood that when the belt; is associated with the pulley 18, it rotates the shaftj17, which in turn revolves the table 11, and when it is'associated with the idler 19, the shaft 17 remains stationary, In accordance with the present invention, the table 11 is adapted to be automatically stopped at each half revolution and incident to this operation, the belt 20 is automatically shifted from'the pulley 18 onto the pulley 19. For this purpose, I provide a horizontally disposed sliding bar'21, which operates in spaced parallel guides 22, which rise from a support 23, andprojecting from this barf21 are spaced parallel lugs 25 between which the-belt 20 operates. The bar 21 is provided witha slot 26to receive the bifurcated extremity 27 of a bell crank lever 28, this lever being fulcrumed as at 29 upon the support'23.-T The bar'21 supports a pin 30 which passes through the slot and also through the bifurcate'dextremity of the bellxcrank lever, so that when the lever'is actuated, the bar 21 is reciprocated toshift" the belt 20 as above stated. The "opposite end of this bell crank lever is connected with avertically disposed rod 32, and the upper end of this rod'is connected with one branch of a bellcrank lever 34,-which is' fulcrume'd on a bracket 35 secured to the underside of the platform-'10. The lever 34 is secured to one end of a short shaft 36 which is'journaled in the bracket 35, and this bell crank lever 84 is actuated ina manner to be hereinafter described to operate the belt shifting bar 21. Projecting from the other end of the short shaft 36' is an arm 37, whichis'connected with the adjacent endof a vertically disposed rod 88, the latteroperating through anopeningj39 in the platform 10 and projecting above the latter. The upper end of this rod 38 is received by an opening in a pivoted latch 40, this latch being pivoted upon the'platform 10 and arranged to overlie the table 11,'and when this latch is operated, it moves intoengagement with a keeper 4C1, carried by the 'table 11, to holdthelatter against movement. Surrounding the upper exposedportion of the rod 38 is'a coiledspring 42, one end ofthis spring bearing against the platform 10, and the opposite end bearing 7 against the latch 40. This spring is comelement 47 which slides through an opening 48 in the platform 10, and is utilized't'o intermittently start rotation of the table 11, subsequent to each automatic stopping there of. Projecting from the shaft 45 is a bar 7 49 and connected with this bar is' a vertic'ally disposed rod 50, which slides through an opening 51 in the platform 10, and has its upper end connected with a latch 52, which is pivoted upon the platform as at 53. This latch is arranged to be moved into engagementwith a keeper 54' carried by the table 11 to hold the latter against movement after each half revolution of the table. A spring 55 surrounds the upper end of this rod andbears against the latch 52 to move the latter into active engagement with its keeper, incident to the shifting of the belt 20 from the'pulley 18 onto the pulley 19.

Connected with the other branch of the bell crank lever 46 is a rod 56 which has its other end connected with one branch of'a bell" crank lever 57 which is on a bracket '58 secured to the underside of the platform. It will be noted that the bell' crank 57 is 'a'rranged substantially in a plane at -ari'ght angle to the bell-crank lever'46 with which it is connected. The other branch of this bell crank lever 57 is connected with thead= jacent end of a rod 59' which extends along one side of the platform and has its other end connected with the adjacent branch of a bell crank lever 60, the latter being pivoted. on a bracket 61 secured to the underside of the platform 10. The other branch of-this bell crank lever 60 is connected with the adjacent branch of the bell crank lever 34 above mentioned, by means of a rod 63, and the arrangement of the parts just de-' scribed is such, that when .the bell crank lever 46 is actuated, it imparts movement to the belt shifting bar 21, thereby shifting the belt from the pulley 18 onto the pulley 19 or vice versa, depending of course upon the particulardirection of movement ofthe bell crank lever 46. The bell crank lever 46 is automatically operated in one direction, that is to shift the belt from the pulley 18- onto the pulley 19, and for this purpose, I provide the table 11' with trip arms 65 gagement with their respective keepers carried by the table 11, and the table is thus held against further rotation. When it is desired to permit further rotation ofthe table 11, it is only necessary tolift the manually operable element 47 ,thereby reversing the movement of the bell crank lever 46 and its associated parts, which of course reverses the movement of the b'eltshifting' bar 21, which carries thebelt from the idle pulley 19 onto the fixed pulley 18, whereupon the table is again put in motion.

While it is believed that from the foregoing description, thefnature and advantages of the invention will be readily apparent, wedesire to have it understood that we do not limit ourselves to what is herein shown and described, and that such changes may be resorted to when desired as fall within thescope of what is claimed.
