TEMPORARY BALE FASTENING-.1

- I Application filed March 2, 1925. Serial No. 12,643.

To all whomiz, may concern."

Be it known that I, ALEXANDER-S. MAO- KENZIE, a citizen of the United States, residing atHouston, in the county of Harris and State of Texas, have invented new and useful Improvements in Temporary Bale Fastenings, of which the following is a specifica tion.-

This invention relates to temporary fastening means for securing wrappers about commodities which it is desirable to enclose within an envelope orv wrapper, and as here disclosed, is shown .in connection with the wrapping and temporarily securing of the burlap or fabric wrappers with which it is usual to envelop or wrap round bales of cotton. W

This development is an improvement on those devices shown in the patents to George R. Brown, Nos. 1,193,506, August 8, 1916, and 1,247,630, November 27,1917. V V

The invention is of the same general type as the devices shown in these patents, and

has the same object in View, namely, to provide a convenient temporary fastening means which may be attached to thewrap j per, and, as that Wrapper is fed through the press during the-step of covering the bale, such fastening means will temporarily hold the cover in snugcondition about the bale ready for thepermanent sewing or-securing .-that this disclosureis illustrative, and in no sense restrictive, as variations from the form here shown, which are within the .skill of the mechanic, or involve thelsubstitution of obviously equivalent expedients, maybe made, and still be within the range of my invention.

In the drawings V Fig. 1 is a view, somewhat diagrammatic, of a round bale press and a portion ofa cover wrapped around thecompleted bale.

Fig. 2 is a view in-plan of the under or pronged side of the temporary fastening device. I.

Fig. 3 is a view in side elevation of the fastening device. I, j

Fig. 4: is a view in end elevation,-glooking from the right of Fig. 2. y

Figs. 5 and 6-are diagrammatic views to The continuous length 01 g the .roll 13 will, of course, be severed. at an show the manner of attaching the fastening device to the cover preliminary to entering the press. v

Fig. 7 is a diagrammatic view showing the action of the fastener as it enters beneath the press roller.

Referring to the drawings by numbers,

like numbers indicating like parts in the several views, 10 indicates generally a press of any desired type designed for forming around balefroma suitable bat of cotton. The formed bale is shown at 11 with the cover 12 partially wrapped about the bale, this cover 12 being generally of-bur-- lap or other suitable fabric, and passing to ,the press in a continuoussheet from the wrapper roll 13, disposed inproper relation to the press. v l

Thebale 11 will, of course, be formedin the usual. manner by feeding the bat down the feed chute 14"to'the rollers 15 of the press, and'when the bale has been formed, the

cover 12 will then be fed into the press, and,

bycontinued operation of the press, wrapped around the bale until it is brought to theoverlapped position indicated at 16 in Fig. 7 f fabric coming from appropriate point between the press and the roll 13, after the bale, 11 has gbeen,c0m pletely wrapped and the ends of the cover Brown noted above, to temporarily secure the cover12 at its lapped ends, in order that when the bale is removed, the expansion ofthe highly resilient cotton will not displace the cover and distort the compressed and symmetrical base.

In my present improvement, this is ac complished by the use of the temporary fastening device shownin detail in F igs. 2,

3 and 4. The device,-as thereshown, comprises the fastener made up of the body portion 17, which, as will be seen in Fig.3,

is-curved,the curvature of this body portion approximating the curvature of a Dress roll 15, as willbe clear from Fig. 7. With the body, portion17 curved as sh'own,-when the fastener passes beneath the roller and issub have. been brought to the overlapped posi fastener to the web offabric, as it descends from the roll 13 toward the press, as shown in 'Figs. 1.,"5 and6.

At theother'end of the plate 17 are the relatively long hooks 19 which have a slight overhang and are intended to penetrate the cover-and bale, as shownin Fig. 7,'when the fasterren-passes'beneaththe rolllo. If desired,'the hooks 19 may be barbed asat 20, seeFig.--1, so'that they will not accidentally withdraw-or spring'out of the baleand cover afteronce having been engaged therewith.

The-fastener 1'? may be conveniently securedto the fabric as itpasses rrom'the roll "to the press, as shown in? igs. 5 and 6. The overhanging hooks 18 W'lllbfi first engaged with the fabric, and after the fastener is brou ht to the )osition shown inlFi 5' the v I") to 7 =30- thrust throu h "the fabric tetheposition a e a 1 a e v *shown in F1 6 althou n lil'Wlll be obvious h k I n :that'the fastener n'nghtbe carried-lnto the press in thB'POSltlOH. SliOWlllIkFlg. 5,'&11l -pressureof the roll 15 will at once thrust the long hooks 19 through the lapped-covers and into the bale.

long relatively st 'aight hooks 19 maybe When the'fastener is in place on-the cover and the coverin'g fabric passes through the press, the hooks 19 wllli-be forced through the lappedends of the coverand into'thebale.

lhe overhanging hooks 18 are securely caught in the fabric, as described, so that a sure temporary fastening of'the cover about the bale results.

Vhenthe'bale is removed from the press,

its natural expansion, when relieved oipressure, will tighten the cover, and"the hooks 18 "andfl19, due to-their overhang,will resist any tendency of the device to slip from place and release the cover. the curved body portion 17, being curved downwardly on the side from whiclrthe hooks project, givesgreat rigidity and re-' 'sistance against straightening under pull of Furthermore the'hooks. even though the device be made of comparatively light metal.

The-body portion 17-will, by reason of its curved form, pass the rollers 15 =withoutdanger of bending and distorting the fastener under the heavy pressure ofthe roll *erspwhich distortion would tend to destroy the etlicacy of the device.

Such changes from the form shown here- 'in'as are equivalentexpedients and do not and relatively long, -'sli 'htly depart in principle from myminvention, may be made and still be within itsrange.

For example, 1 have shown a fastener having a plurality of-hooksat each end. It is conceivable thata fastener might be provided with. a single hook at each end. Agaiinthe fastener is shown as made of a solid plate of metal, but it would be entirely witl'iinthevrange of my invention. to make it in skeleton form, or fabricated of wire of suitable gauge. Such changes would, of course, merely call for mechanical Skillyfllld be patent variations'of my invention.
