7 This'invention relates to improvements in if spoolingmachines, and particularly to machines for spooling veneer, or the like.'.

' Explanatory to the invention, it; willv first'stated that it is now common practice in the. manufacture of veneer, to transferv the trimmin machines and because of theibrit-f tleness of the product much waste or mate 5 rialoccurs in handling due to cracks, splits, etc.', -which. must be cut/out. Also, there is much delay necessitated because of the care required inithe handling ofthe long and frag-. ilestrips.

venti-on t'o provide means whereby they may be avoided ,LWhereby the handling of the ve user stripmay be expedited: and the material safely and moresatisfactorily transferred fromthe lathe or peeler to the trimming mad-.

chines. c

More specifically,

to operate in conjunction with the peelerfor win'dingrup the istripzofveneer as it comes the rate of winding so as-totake up the stripas it comesfrom the peeler and there being p means for adjusting the spool to correct any unevenness that might occur in the winding operation.

Other .obj of construction and in the combination of hereinafter be'olescribedr i i 5 In accomplishing these and other objects of theinvention, we have provided the improved details of constructiomthe preferred panyi'ng: drawings, wherein Y H e i 'coaxially thereto, as in Figure 2, and about In view of'the above and other disadvam 7 tages encountered inthe usual way of han-f dling veneer, it has been the objectof this'inv p heinventionresides in 30 the prov-ision'of. a-spooling machineadapted ects reside in: the various details parts and in their mode of operatiom-as will forms of which 'are illustrated in the-accomv p p about beltwheels26and 27'fixed, respective 100 Figure 1 is a plan view of a'veneer spooling machine embodied-by thepresentinvehtlon. i Figure 2 is" an elevation, showing the windmgiSPOOl in longitudinal section Figure 8 is an-end view ofthe machine. showing the driving mechanism; a

lieferring more indetail to the drawings The present mechanism consists of thespool 1, onto which the veneer strip 2is wound as it is peeled fromthe log,- designatedat3 in Figured This spool,,in a preferred form, consists of asupporting, or centralshaft 4, with a plurality of cylindrical frames 5' fixed which the veneer strip is wound these frames I being of equaldiameter andeach having "are slidably keyed to the shaft'an'd are"ad-' I Justable thereon to accommodate strips of differentgwidth. v

p Thespoolissupportedat itsoppositeends from 1 frames designatedfin their entirety at and 9 each" of which comprises suitable p right members 10 and horizontal cross beams 11, all of which are suitably connected and braced to form rigid and substanti'al'frames. Mounted horizontally on these supporting frames in coaxial alinement; are" spindle '5 shafts 12 and' 'lgwhichhave end portions 14:

projected into endsockets '15 in the ends of the spool axle to supportjthe spool.

'n 'lhe-spindle 12is designated as the driving spindle 'iL'IlCl'llTlS revoluble in bearings 16 and 0 17 fixedon the cross beams 11 ofthe frame 8.

driving gear wheel22 on a shaft 23 adapted to bei driven'by an electric motor 24 through the intermediacy of a belt 25 which operates end of the machine. Manipulation of-this' lever, whereby the wheel/31 will be pressed againstthe belt, tightens the latter and'the spool will then be driven. When the belt is loose no driving action takes place.

A speed control brake drum 81 is keyedor otherwise fixed on the shaft 23 and about this a brake band 82 is fitted. A rod 83 connects the band with one arm of a bell crank 84 which has its other arm connected'by a rod 85 with a control lever 86. Preferably the lever 86 would be located near the lever andthe two are manipulated together to control the speed of winding,

The inner end of the spindle shaft 13 revolubly supports the end of the spool shaft. This spindle shaft is threaded through supporting bearings 40 and 41 that are slidably adjustable on the supporting frame 9 in a direction lengthwise of the supporting beams 11.; ,This sliding adjustment is made in order to'provide for shifting that end of the spool from ortoward the peeler to correct anytendency of uneven winding of the veneer strip.

Adjustment of the. bearings is accomplished by a pair of shafts 43 and 44 which are revoluble in supporting bearings 45 and 46 and have their inner ends threaded, as at 47, through lugs 48 formed on thebearings. Bevel ear wheels 49 arefixed to the outer ends 0 the shafts and these are adapted to be rotated together by bevel pinions 50.,on a cross shaft 51 mounted in bearing, brackets 52 and 53.1 A sprocket wheel 54 is fixed to shaft 51 in alinement with a sprocket wheel 55 supported at one side of the frame by a bracketf56 and adaptedto be rotated by a crank 57 and achain belt'58 extends about the sprockets. The construction is such that rotation of shaft 51, by means of the sprocket chain connectionwith crank 57, causes rotation of the shafts 43'and 44 and since they have no longitudinal movement and are threaded into lugs 48, they cause the shifting of bearings 40 and 41 to move that end of the spool accordingly. This adjustment is indicated in dotted lines in Figure 1. By this adjustment, tendency of the veneer strip to run toward one end or the other of the spool may be corrected and even winding maintained.

For adjusting the end of the spindle shaft 13 lengthwise into andfrom the end of the spool, we have fixed asprocket wheel 60 rat the outer end of the shaft in alinement with a smaller sprocket wheel 61 supported from s chain belt 64 is extended about the sprockets 60 and 61 so that, by rotation of crank 63, the shaft 13 will be rotated and thereby threaded inwardly or outwardly.

In use, the spooling machine is located adjaeent the peeler, as designated in its entirety at 75 in Figure 5. This machine embodies log mounting means 7 6 whereb the log is rotated against a knife 77 held a justablyagainst the log. The strip of veneer cut from the log is wound onto the spool by rotation .of the latter through the driving connection with motor 24, and the rate of winding or the winding action is governed by the manipulation of thehelt tightener by lever 35, and the brake by lever 86. Should the strip wind unevenly on the spool, correction is made by shifting of theibearings 40-41 which moves that end of the spool closer to or away from the peeler. When the spool is filled, it is released by withdrawing the endv of shaft 13 from the spool end. A suitable track, as at 90 in Figure 5, and cars riages 91 may be employed for transporting the filled spool to the clippers or trimming machine.

While we have not so described it, it is quite apparent and it is intended that machines of this samezconstruction be employed also in connection with the clippers to unwind theroll as the strip of veneer is fed to these machines.

'It is quite apparent that, in this way, a great saving in space is provided with a much easier and less expensive operation. Italso provides for a great saving in veneer as this eliminates the cracking or splitting of dried sheets that occurs when the lengths of strips arelimited to the lengthof the transfer tables or decks. V

It; is also to be noted that all the adjusting devices, -viz., the cranks 57 and 63 and lever 35 areadjacent the same end of the machine,

easily accessible to the operator, and that there is a perfect control of the winding operation at all times. a

,It is also to be understood that various details of construction may be changed withtion.

Having thus described our invention, what we claim as new therein and desire to secure by Letters-Patent, is: s

a 1. In a spooling machine for veneer orthe like, a frame structure, a set of'beari'ngs fixed to the frame, another set of bearings spamd therefrom and slidably adjustable on the frame, a spindle shaft revolubly mounted in the fixed bearings, a spindle shaft threaded through the adjustable bearings and arranged substantially in axial alinement with out departing from the spirit of the invens the revoluble spindle, a spool disposed between adjacent ends of said spindles and having end sockets receiving the spindle ends and havinga driving connection with the revoluble spindle, means for driving the'revoluble spindle to rotate thespool, means for bodily shifting the adjustable bearingslaterally to vary the angular relation ofthe spool with I respect to the line'of delivery of veneer thereto and means for rotating the threaded spindle to adjust it endwise to release or retainfthe spoolrj 7 v 2. The combination With aveneer peeler, of a spooling machine comprising spool sup- H [5 porting and driving means, a spool mounted j therein for receiving the veneer sheet from the peeler, a brake mechanism for controlling the speed of the driving means to take up the I sheet as delivered, and'means for adjusting the angular relation of the spool with respect to the line of delivery to maintain even inding and means for controlling the brake mechanism.
