LATI-I -PULLING MACHINE.

Application filed July 2,1920. Serial No. 393,571.

To all whom it may concern:

Be it known that I, WALTER A. SKINNER, a citizen of the United States, and a resident of Burnside, in the county of Hartford and State of Connecticut, have invented a new and Improved Lath-Pulling Machine, of which the following is a specification.

My invention relates to the class of devices employed for withdrawing lath or similar supports from the tobacco stalks and upon which the latter have been impaled in the process of drying, and an object of my invention, among others, is to provide adevice of this class that shall be simple in construction: and particularly efiective and rapid in operation. v I

One form ,of device embodying my invention and in the construction and use of which the objects herein set out, as well as 1 improved tobacco lath puller comprises aframe made up of end supports and an inter mediate support. One end support includes two posts 7 rising vertically froni-a base board 6 at opposite sides thereof and joined by a cross bar 8, while the other end support comprises a post 9 risin vertically from the base board at one side there-one side post 10' extending diagonally upward from one side of the base board, abrace 11 and a cross bar 13. The intermediate support is similar in. construction to the end supports just described having in addition to the parts thus described a vertical post 14 secured at its opposite ends to

cross bars

12 and 13,.

I said cross bars 13 on the intermediate and end supports extending diagonally upward from the sideposts. a

A rackfor tobacco lath "is arranged between an end support and the intermediate support, this rack comprising a bottom board 15 secured to the cross bar 8 and to the] bottom cross bar of the intermediate support with cleats 16 extending outwardly from the bottom board forthe-lath that fall from above after the tobacco has. been stripped therefrom. Strips 17 extend upwardly from the bottom board toform a back for the rack.

The intermediate support and end sup ports together with the board 15,: cleats 16 and the posts 17 form a stripper section of the frame, which section also includes guide bars 18 extending lengthwise along opposite sides of the section at the top thereof, the bars and posts thus far described being preferably composed ofangle iron, the bars 18 having. the horizontalparts of the angle iron composing them projecting inwardly to form guides for a stripper to be hereinafter described.- v a i a The intermediate support and the end support comprising the post 9 make upa feed section of the frame that also includes rests 19 secured to theupper sides of'the upper top cross'bars, these rests being of considerable width, andvthe end and intermediate supports being spaced apart 'a distance to permit the ends, of thelath to rest upon said rests, and sides 20 are provided as an aidin retaining the-lath in place, said sides and rests in fact'providing a sort of trough in which the lath-are placedwith the tobacco (stems and-leaves) depending through the bottom of said trough, Thistrough slants downwardly from the feeding or front side of the frame, and the rests are preferably so positioned thatthat part thereof in line with a line drawn centrally between the guide bars 18 will be substantially in the horizontalplane of the guides on said guide bars, 1 a

- The stripper comprises a slide including a base 21 with guideways 22 thereon, the

latter, in the structure herein shown, vbeing formed by riveting strips of metal to the upper side of'the base to provide grooves constituting said Iguideways, and as shown in Figure 4 of the drawings, Gripper aws 23 are pivotally supported on the under side of the base 21 these jaws eachbeing preferably of angular shape with the vertical part constituting the gripper jaws proper.

Connecting bars 24: are pivotally. "attached at their ends to the gripper jaws, the opposite ends of said bars being pivotally connected to a gripper jaw actuating bar25 having a slot to receive studs; projecting from the base. This actuating bar receives a connecting rod 27 that is pivotally attached to a gripper operating lever 28 pivotally secured at its lower end to the base board 6. A pitman 29 connects the lever 28 with. a crank pin 30 on a wheel 81 and by means of which the grippers are actuated.

This wheel 31 is secured to a shaft forming part of av reducing mechanism located in a case 82, said reducing mechanism being driven as by means of a motor 33 located on top of the case 32, this motor preferably being of the internal combustion engine type, but it will be understood that any means for applying power to the grippers may be employed as conditions may require.

A stop bar 34 is secured to the ends of the guide bars 18 and to the side of one of the rests 19, as shown in Figure 5 of the drawings, thisstop bar serving as a stop to engage the tobacco stems and hold them against movement when the lath are being withdrawn from the incision Within the stem.

In the operation of the device the lath on Which the tobacco is hung are placed in numbers on the rests 19 with the tobacco hanging from the lat-h. These lath are placed in succession with the ends that rest on the intermediate support in line with the opening between the gripper jaws that are reciprocated by the mechanism hereinbefore described so that they will pass across and slightly beyond theintermediate support and the ends of the lath on this support. As the grippers approach the end oftheir path of movement forwardly or toward the lath the ends of the latter are received between the gripper jaws, that, at this time, are open, said jaws having been opened by the opera tion of the actuating bar 25 moving forwardly on the base 21, which forward movement was permitted by the studs engaging a slot 26 and comprising the connection between said bar and said base, at the time said bar commencedits movement to operate the grippers. In the reverse movement of the grippers as the actuating bar 25 begins its backward movement, or movement away from the lath, the stud and slot connection with the base 21 causes the first part of said movement to be independent of said base,

the latter remaining stationary, with a re-' sult that the connection of the actuating bar with the grippers causes the latter to be closed upon the latter before the base begins to move backwardly. When the forward stud is located in the forward end of its slot the base 21 begins to move backwardly, drawing the lath and tobacco thereon with it until the upper end of the tobacco stem nearest the stop bar 34 is drawn against said loan A continued pull upon the lath causes the stems to be drawn together and the lath is drawn through the stems and to a. position overlying the rack in the stripper section of the frame. As

the stripper begins its return or forward movement the jaws are opened as hereinbefore described and the lath is released and drops on to the bottom board 15, after which. the operation is repeated.

it is noted that the angular arrangement of the jaws 23 with respect to each other provides a flaring opening widest at its end nearest the lath to receive the lath ends.

I claim 1. A tobacco stripping machine including rests spaced apart to receive the ends of lath with tobacco depending between them, said rests being disposed in an inclined plane, a stop overlying oneof said rests providing a space between said rest and the stop for movement of the end of a lath, and a stripper including a pair of jaws movably mounted with the opening between the jaws in line with the end of a lath supported on said rests and underneath said stop.
