EUGENE QHOLMGREEN, or sAN ANTONIO, TEXAS v coTToN TRAMPER i Application filed August 4, 1928. Serial No. 297,490.

This invention relates to improvements in packing or tramping machines, and more particularly to cotton trampers for use in baling cotton. The invention consists in cer'- V tain improvements in the mechanism for op` erating the tramper, whereby aV rigid ma#y chine is provided. In trampers now 1n use a series of chains carrying crank pins is propaelernwThe vsupporting beams 10.and 11.

videdv through which a reciprocating movement is secured bythe pinstravelingwith the chain. This construction results-in great uncertainty in the alignment; and action `of j the pins and their connections.. MyV construcf tion aids to correct this uncertainty by introducinga positive moving'connectionthat will alwaysfunction in astraight line, and

hence notgbe subject to uncertain movements.

Referring to the accompanying drawings,

which are made apart hereof and on which similar reference characters indicate similar parts, e y

' Figure 5,V a parti l plan view with the tramper beam shown in section, and

Figure 6 is a view similar to Fig. 5, of a modilied form.

My device is mounted upon two parallel beams 10 and 11, preferably of steel or casteV iron, held'together'by suitable cross braces.

Supporting standards 12 and'13 are mounted in a vertical position upon the base and are held in an upright position by braces 14 -and 1,5. The upright members12 and 13 provide guides forthe reciprocatingV cross head which operates the tramper or, packer. These guides consist of rods which'have reducedthreaded ends, the lower end passing through a flange in 'the beams and. having nuts 16thereon and the upper en d passing into and through a top casting 17 and having ,nuts 18 thereon. The standards12 andv 13 have steel lugs 19 and 20welded near the upper ends, Yor otherwise V'secured thereto.

The 'supporting braces 14 Vand l5`ar'e hollowk v 47 which provide bearings for a shaft 48-car l and have rods 21 extending therethrough.

Nuts 22 and '23 secured on the ends ofjtheA rods holdthesupportingrbraces 14` and 15V in position. The lowerL end of the braces 14- and 15 preferably seat in sockets 24 in lugs. whichare welde'dto the'top of the beams 10 and 11. This structure provides a rigid support for the. standards which 'carry the have bearings'25, 26 and 27 welded thereon,v 60 i /or otherwisesecured. These bearings carry 1;

shafts 28, 2 9v and 30.y Upon these shaftsVV arey secure'ddriving gears 31, 32 and Uponf the outer end of the shaft 28 is mounteda' pulley or other suitable means for receiving power from an engine or other suitable source of'powennot shown. The gear wheels 33 have cranl; pins 35. These crank r`pins carry one endv of connectingrods 36a nd 37.- 'l The connecting rods are held upon the crank pins bolts 38 which pass through the'cranlr` pins and secure thereon-washers 39. The con- `nectingrodbearing is composed of twomem-i bers 40,and 41. These members are heldvftogether by the long U-bolts or otherwise, which pass around cross head pins 62and 63 on the cross head 43: This cross-head carries cast; ings 44 and 45v which slide vupon the guides 12 and 13.. The castingsalsohave lugs 46 and lrying a guide roller 49. The cross head also carries a pinion 50 mounted upon a shafty 51.-;- A standing beam or rack 52 is secured upon a cross brace on the beams 10-and11. This ,f

standing vbeam hasa seriesof bars 53 secured'v 85 l in holes'in the Vlianges `ofthe beam.k These, bars providea rack on one side of the beam whichvis enga-ged bythe teeth'on the pinion 5Q. The tramper 54 is made of a beam'similar to the standing rack1beam52, and-has rods 55.securedinthe flanges on the beam correspondingv to those on the standing beam 52. The lower end of the tramper beam 54 has arectangular block 56 securedgthereupon, and

kthis rectangular block has slats 57 secured '95rr onits underside. Secured to the under side,y of the beams 10 and' 11 `are brackets 58 and 59;'5

yThese brackets engage the flanges of the., y beam 54 and guide it.during. ;reciprocation.".V 'Thecasting 17 has bolts 60 and 6l threaded `V10o bolts 60-and 61 are preferably welded tothe therethrough, the nuts 60 and 61 allowing an endwise adjustment of the bolts. The

This form providesmeans for varyngthe.

length of the tramper stroke. In this form, instead of the pinion'50, I use a pinion 64 which meshes with the bars on the beam 52 only. On the outer ends of the shaft which carries the pinion 64 I mount pinions of a larger diameter which mesh with bars 66 eX- tendingvbeyond the outer sides of the flanges on the beam 54. Vertical movement of the crosshead in this form will move the tramper through a distance somewhat greater than twice that through which the pinion 64 y moves. By changing the relative size of pinions 64 and 65 the length of the stroke of f the tramper may be regulated as desired.

`If desired, the pinion 65 mayV engage the stationary beam* and the pinion 64 the tramper beam `so that the tramper-stroke will belless thandouble the stroke of the cross head. Y Y

The operation of thevdevice is as follows:

VPower is applied to the pulley 34 which drives-the shaft'28, and through the medium" of gears 31, 32 and 33'the connecting .1 rods 36 are reciprocated, and in turn they reciprocate cross head 43. rIhe pinion 50 rotat'ably secured on a shaft through the cross head vengages the racks 53 and 55 on the stationary beam 52 and the movable beam 54 respectively. Since the beam 52 cannot -move, vertical movement of the cross head willrotate the pinion to .move the tramper beam 54 vertically through a distance twice that through which the cross head travels. By using the formfshown in Figp, the

...tramper may 'be' caused to move through a distance more or less than twice that through which the crosshead travels. Y The roller 49 engages between the flanges on the rear side of the tramper beam 54 and holds it in posi- -.Ltion. VLu'gs 58 and 59 guide the lower end of the tramper beam during its vertical re- Y ciprocation.

The U-bolts 42 which pass around the upper lend of the crank pins 62 and 6B take'the strain off the bearing mem bers 40 and 41 and distribute it between the two crank pins. The Usbolts 42 also carry some of the strain which otherwise would be put 'upon the connecting rods 36 and 37.

While I have shown and described my invention as applied to a cotton tramper, it

should beapparent that it need not be limited to this use.V It may find utility iny devices where specially long strokes of a plunger are desired with a short stroke operating plunger, such for example as the pis` ton or plunger in a cylinder. Among possible ields of utility would be as a hay press or a pumping jack for raising water, oil or other liquid, since the tendency in modern practice now is toward longer strokes in malmy device without departing from the spirit of the invention, and I, therefore, do not limit myself to what Vis shown in the drawings and described in the specification, but only as set forth in the appended claims.

I-Iaving thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
