Application Cctober 24, 1952, Serial No. 316,646 2 Claims. (Cl. 153-104 straighten and tension the baling wire-as it is bound about the bales produced by such machines.

'It, is among the objects of the invention. to provide an improved wire straightening and tensioning device which can be applied as an attachment to an existing -baling machine to straighten and tension the baling wires as they are bound about the bales produced by the, machine; which can be installed on an existing machinegwith no material modification of the-machine construction, which are adjustable to vary the tension provided -on the baling wire; which are efiective to straighten without breaking orstretching the wire; and which are simple and durable in construction; economical to rnanufacture and positive and effective in operation.

* Otherobjects, and advantages will, become apparent from .a consideration of the following description and the-appended claims in conjunction with the accompanying drawings, wherein: n 3 1 j r y Figure l is a front elevational view of a wire straightening and tensioning device illustrative of the invention; Figure 2 isatop plan view of the.device illustrated in Figure 1 witha portion broken away and shownin cross section to betterillustrate the construction of the device;

1 construction thereof. t

, liWith continued reference to the drawings, the,wire

straightening and tensioning device comprises a: frame in the form of a metal plate 10-of elongated, rectangular shape having at its fmidlength location a transversely extending, closed slot 11 and spaced apart apertures therein at each side of the slot. .Guide bars 12 andl13 extend transversely .of the. plate 10 one near. each. end of the plate and at the same side thereof and these guide bars are secured to the plate by suitable means, such as the bolts 14 and15 for the bar 12 and the bo1ts'16 and 17 for thebar 13. The bolts -14 and l5-ex tend through registeringapertures in the bar 12 and the plate andare disposed one near each end of the bar ;and arje provided with nuts'bearing against the side ofthe plate -10 remote from the bar 12 to firmly clamp. the -has ih the' plate. The bolts 16 and ,17 extendthrough registeringapertures inthe bar 13 and theplate 10. and

g e, disposed one: near each, end of the barandproyided with nuts bearing against the side of the plate 10 remote 2,746,513 Patented May 22, 1956,

aperture is substantially parallel to the longitudinal center line of the plate 10 and the bar 13 is provided-with asimilar aperture19. A slide block 20 of elongated, rectangular shape is disposed against the .side of the plate 10 remote from the bars 12 a'nd13 and in overlying relationship to the slot 11 in the plate 10 and has at one enda perpendicn larly projectingflange 21 overlying the adjacent edge of the plate 10. The flange 21 is providedwith-spaced apart, screwthreaded apertures and set screws 22 and 23 are threaded through these apertures and are disposed perpendicular to and bear against the edgelof. the plate 10 adjacent theflange 21 to hold theslide block.20 in selectedpositions of adjustment transversely of the'plate' 10. These set screwsare provided with lock nuts 24, and 25 respectively, which bear against theflange 21 arm slideblock 'to lock the set screws in' adjusted position The slide block 20 is provided with an aperture'26 which registers with the slot 11 in the frame plate. 10

and a journal pin 27 has a screw threaded end 'portiori 28 extending through the aperture 26 The journal 27 projects from the same side ofthe frame plate'loj as that from' which the guide bars 12 and 13 }projectfand is provided at its end remote from the-screw,.th r ea ed portion 28 with a head '29 .of polygonal shap 1 Betw en the head 29 and the screw threaded portion 28 thejour nal pinhas a bearingportion 30 of a diametensomewhat greater than thediameter of. the end portion, anda roller-31 having spaced apart peripheral grooves 32 and 33 is journaled on the bearing portioi1'30j of the journal pin 27.

As is particularly illustrated in'FigureJ, the journal pin 27 is provided in the head 29. thereofwith aiscr'ew threadedwe'lI or recess 34 and in the bearing, portion thereof with a transversely extending lubricant passage 35 connected to the inner end of the recess 34 by a passage 36 extending longitudinally and substantially coaxially of the pin. A grease pressurefitting37 of well .known construction, is threaded into the re,ces.s.,3 4 for supplying lubricant through the passages 3.6 andQ35 'to the bearing between the roller 31 and ftheffbear ing portion 30 of the journal pin.

' i The bearing portion30 of thejournalpin hasa by the length of the slot 11 by first-loosening tthe wing I nut. 38 and then turning the set screws 22 and ,23tuntil the slide block 20 is moved to a positiontransyersely of the plate 10 corresponding to the desired position of the roller 31 relative to the plate. Thelock nuts 24 and 25 on the-set screws are then tightenedto lock-,the, set

screws in adjusted position and. the wing nut-.38 is tightened on the journal pin 27 to firmly clamp the slideblock ..against the frame plate. 1

Journal pins 40 and 41, similar in allrespects, to ,the journalpin 27, extend through apertures provided; inlthe plate 10 at respectively opposite sides of the,s lot 11 spacedsubstantially equal distances from this slo the same direction from the longitudinal center liile of the ffarne' plate.
