To all whom it may concern:

Be it known that I, HENRY ROBERTS, of

Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Veneer- Package Machines, of which the following is a full, clear, and exact description, reference being had t6 the accompanying drawings which form part of this specification.

My invention relates to that class of veneer package machines in which a collapsing drum in cooperation with pressure means is employed to form the package; the pressure means comprising usually a- A compression roller by means of which the material is wrapped on the revolving drum and the presser plate for holding, in the formed package, the overlapping end of the material in position for fastening. The object of my invention is to improve the construction of the forming drum; providing a drum which may be effectually and readily collapsed and established; also to so construct the compression roller as to be instrumental in insuring symmetrical application of the stiffening hoops when employed to the body of the package. I also aim to improve certain" other details of construction, as will be hereinafter more fully described.

I will now describe my invention, referrlng to the accompanying drawings, so that others skilled in the art to which it appertains; may understand and "construct the same.

Figure l is a side elevation of a Veneer package machine embodying my invention; Fig. 2 is a front elevation of the same partly .in section; Fig. 3 is a vertical sectional view;

Fig. 4 is a longitudinal sectional View of the forming drum; Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 4; Fig. (i is asimilar View but showing the drum contracted or collapsed; Fig. 7 is a fragmentary perspective view of the adjustable hoop guide; Fig. 8 is a fragmentary elevation of one end of the drum; showing means for holding the collapsible "drum segments in normal extended position; Fig. 9

is a front elevational view showing auxiliary means for supporting the drum during endwise removal of the package therefrom; and

Fig. 10 is a sideele'vation of the auxiliary.

drum supporting means.

' The'refei ence numeral 2 indicatesthe usual'drum carrying shaft or splndle which is journaled in the bearing 3-l of the main frame 5 of the machine; thc'end bearmg i being carried by the arm 6 which is pivotallycarried by the'frame 5 so that it may be shifted to clear the finished package in its endwise removal from the drum. The former or drum 7 is provided with the inwardly foldable segments or leaves 8 whereby the drum is rendered contractible or collapsiblc to enable removal therefrom withoutbinding of the finished cylindrical package. To permit of such collapsing of the drum as well as to cause a return of the leaves 8 to normal position for cylindrical establishment of the drum I provide the internally radially or substantially radially shiftably mounted arms 9 which are provided each with the head plate 10 by means of which the leaves 8 are held normally open. as shown in Fig.- 5, and upon which one of the leaves slidingly bears as the leaves are ferring to Fig. 6. Such radial shifting. spoken of above, of the arms 9 is brought about ,by means of the rotatory rod ll through the medium of pinions 12 which mesh with the toothed-face 1.3 of the arms 9; the rod drum 7 and having one end square-finished as at 14 for the reception of a suitable op-. erating handle (not shown). Locking (if the arms 9, when caused to be shifted to the .position shown in Figs. 4 and 5, is accomplished by means of the suitable ratchet and pawl arrangement 15 which serves to prevent a' reverse rotation of the shifting rod 11 after the rod has operated through the pintend the arms'9 in the mannerdescribed above; the ratchet being carried by the rod '11 while the pawl of the arrangement is carried by a respective end face or web of the drum 7, as is clearly shown .in Figs. l and 8.

Positioned preferably at the top .oftthe drum 7, is the compression roller '10 by means of which the package material is caused to be firmly wrappedvupon the revolving drum 7 This roller 16 is carried by theblocks 17 and 18 which are slidiugly mounted inthe uprights 15) of the main frame 5;'t.he blocks 17 andlS being provided with the interposed coiled springs :0 by means of which a cushion effect is given to the roller 16, Means for causing shifting of. this cushioned or compression, roller 16 folded inwardly, as will be readily seen by rc- 11 being carried by the main portion of the ions 12 and gear face 13 to shiftably err-- intoand out of. operative association with the hoop guiding (so -press1on roller 16 as to alining the hoops asthey1 through revolution of t the package.

operatively rotatinig the forming drum 7, comp rlsefthe twin screw feed arrangement 21,'carried by the frame 5 and which, operatively engages with the shiftable block 17 of the roller. .A suitable hand wheel 22 serves, through the medium of the beveled gearing 23, to form operating means for the screw feed; T

The usual clamping or Presser bar for holding the overlapping end of the formed package in position for fastening, .is inclicated by the numeral 24. This presser bar, in my improved apparatus-,- however, is adapted to be operated by means of the twin screws 25, which correspond withthe feed arrangement, above described, of the compression roller 16; the hand wheel 26 forming, with the beveled gearing 27, means for the screws 25. Pivotally carrie by the upright members 19 of the frame 5 are the arms or brackets 28 to which is secured the rack 29 which extends, adjacent the presser bar 24, across the face of the drum 7. Carried by this rack 29 ere'thehoop guiding fingers 30 between which the stiffening hoops pass in their presentation to the drum; the fingers being adjustably'mounted on the rack 29 so as to accommodate hoops of various widths. 2

As shown in Fig. 7 this adjustability of fingers 30 is accomplished by forming a lon 'tudinal slot 31 in the rack 29, in which t e fingers 30 are mounted; each finger beingprovided with the T- head 32 against whichthe bar 33 is adapted to. be clamped by meansof suitable clamping screws 34 for holding the fingers in adjusted position along the rack. And by means of the pivoted'mounting of thghoop guide rack carrying arms 28, desired angular adjustment of the rack '25 may be had. To effect such adjustability of the rack 29']: fi x'edly secure the arms 28 to their pivoted mounting or shaft35 which is journaled in the frame '5 and provide such shaft 5 with the adjusting lever or arms 36 (see Fig. 1) carried by which is the clamping screw 37 which is adapted to cooperate with the slotted clamping plate 38 to hold the said lever 36 in adjustedposition Such angular adjustability also permits of the rack 29 being swung upward'to an inoperative position after serving to guide the hoops in their to the veneer body, for 'con venience in the nailing 'or fasten ng of the overlapping end of the material. I

To insure symmetrical disposition of the stiffening hoops in their application-Ito the body of the package, I so construct thecombe instrumental in: are caused to pass, e drum 7, between the compression roller 16 and the body of structed is clearly shown inFig. 2 and com- The compression roller so conprises the rolls 39 carried by the journal 40. These rolls 39 are arranged in sets of two rolls each; the rolls of each set being provided withoppositely disposed recesses 41 by means of-which they cooperatively assist to, prevent lateral shifting of the traveling hoop. By means of the suitable set collars 42 the rolls 39 may be adjusted along their journal or shaft; such adjustment contemplating the accommodation of the recesses 41 to hoops of various widths.

The usual circular saw for dressing the ends of the cylindrical package before it is removed from the drum, is indicated by the numeral .43; The saw shaft or spindle 44 is journaled in the bearings 45 which are slidingly mounted in the standards 46 situated beneath the drum 7. J ournaled in the standards 46, parallel with and beneath the saw spindle, is the rotatory shaft 47 fixedly carrying the eccentrics 48 which, by a rotation of the shaft 47, serve, through the intermediary of the bearing rollers 49, to slidingly shift against the tension of the springs 50, the shaft 44 for presentation of the saw to the revolving package. To the eccentric shaft 47 is secured the pinion 51 with which meshes the segmental rack 52 of the lever 53,

. pivotally carried by a standard 46. It is evident that by a rocking.- of the lever 53 a. rotation, by means of the pinion 51 and rack 52, ,of the shaft 47 will be set up for a shifting of the finishing saw 43 into and out of operative enga ement with the formed -pack age, as above described. InFigs. 9 and 10 I show meansifor supporting the respective end of the drum when the arm 6 is disengaged from the-end of the of the finished package. comprises the support 54 which is vertically shiftably mounted in the frame 55 beneath the drum 7. This support is provided with side of the saw spindle 44, and in which are journaled the drum supporting rollers 57. And pivotally mounted on the frame 55 and operatively connected to the support 54 is the lever 58 by means of which the support 54 may be elevated and loweredfor bringing the supporting rollers 57 into and out of supporting association with the forming drum. The lever 58 is provided with the suitable "pawl 59 which is adaptedto engage with the ratchet face 60 of thepawl 55 for holding thev drum support 54in elevated operative effectually support the drum against sagging date the simultaneous formation of several shaft 2 preparatory to the endwise removal This mechanism the arms 56 which extend upward at each position. "This roller arrangement serves to.

while still permitting of the ready removal I during removal of the package,

packages; the continuous cylindrical package being adapted to be severed or cut to the desired lengths without removal from the drum, means of the intermediate saw 43 operating in conjunction with the peripheral drum-recess 61. The operation of my apparatuswill be readily understood from the foregoing description. Any suitable means may be emup of the hoops after passing from the recessed roller 16. I

The advantages of my invention will be appreciated by those skilled in the art. The apparatus is simple, compact, and symmetrical in construction and effective in operation.
