Tojall whom; it may concern: "j Be it known that I, SECONDO L. CAsELLA,

a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Automatic Basket-Machines, of which the following is a specification. i l

' My invention relates to an'apparatus which is designed for the purpose of manufacturing veneer baskets and completing the whole in, a sin le continuous operation.

action of the chucks 53.

It's the object of my invention to provide an apparatus in which'a plurality of thin'v'eneer sheets previously prepared are carried .to a 'common center, crossed or overlapped,

and bent so as toforrntheupturned sides and a meansgby which foldedstripsof metal are brought into position with relation to thefolded veneers, bent, applied to theupper edges of the veneer, overlapped, compressed,

Fig. 9 is a verti- Fig. 18 is a section ew showing the and locked in position and. thebaskets thus finished :finally discharged at the end of the machine.

As shown in the drawings, my apparatus comprises a base of any suitable construction, as at A, this base having standards B suitably dis osed to .carry the operating mechanism. This mechanism comprises two tables 2 and 3, which are disposed substantially at right angles from each other and are adapted to receive the previously-prepared thin sheets of veneer which are supplied to the tables, and these tables are-provided with a reciprocating mechanism which acts to carry one veneer on each table to a central point, where one is superposed upon the other in readiness for the forming process. The veneers are laid horizontally and flatwise upon the guides 2 and 3, and in connection with these guides are'reciprocating carriers 4, which are operated by links 5, connecting the carriers with 'fulcrumedlevers 12, and cams, as at 6,which are revolved so as to reciprocate and move the carriers at the proper intervals. The carriers have upwardly-projecting pointsor spurs], so disposed that several of the veneers may be in process of transmission toward the center at all times, and the movement of the carriers is sullicient to deliver one veneer at. each forward movement while -the others are being advanced an equal amount by said movement. The carriers, with their upturned spurs, are moved forward in such plane that the spurs will engage the rear edges of the veneers and advance them. Then the carriers are depressed so that the spurs return beneath the veneers which lie in position upon the guides, and the s ur s are again projected upwardly behind the veneers, thus advancing the same intermittently until they are delivered at the central point.

vation of these carriers is effected by means of hell-crank levers 8, connected by a rod 9 with a pivoted lever 10, and this lever is actuated by a cam, as at 11, so as to cause the alternate elevation and depression of the carriers. These carriers are reciprooated by means of rods connecting them with rocking levers 12, which are fixed upon-the shaft havinga short rocker or crank arm 13, and tlns isconnected a'rodor pitman' 14 with asuitable cam or The alternate depression and eleare continuous with guides on t eccentric 6, by which the reciprocation is effected. The two sets of levers are so actuated in unison with each other that while the spurs or points by which the veneers are advanced are in their elevated position the forward movement of the carrier takes place, and when this forward movement is completed the depressing mechanism acts to lower the spurs so that they are retracted beneath the veneers,-as previously described. I One of the veneers is advanced directly to the central point and the other is slightly above the level. of the first-named veneer, so that it will be moved in just above and overlapping the first veneer. The guides of the u per veneer lie plungeryoke, so that the veneer is guided to its osition, and when the plunger'20 descen' s to press the veneers together and to bend them the edges of the veneers will be withdrawn from the guide-channels, which have but lit tle depth. Springs, hereinafter described, prevent the displacement of the veneers. The veneers thus overlapped and standing transversely to each other are then delivered in position above the bending-frame 18 and in line with the plunger 20. There are four of these frames supported 11 onl four equally-spaced arms, as at 19, whicli roject radially from a central shaft, by \vhic shaft this portion of the structure is revolved. The shaft is revolved intermittently, so as to carry each of the four arms forward a quarter of a revolution, and during theintermission in the movement some action toward the completion of the basket is effected. The first action after the veneers have been placed transversely upon each other is to depress them within the inclosing framework 18, and this is effected by means of a plunger 20, connected with a vertically-slidable guide 2]., and this is actuated by a rocker-arm 22, connected by a rod 23 with another rocker-arm 24, mounted upon a shaft which carries an arm 25, and this lever-arm is provided with. a pin or roller adapted to engage with a cam 16, by which 6,5 dially from the shaft 29, whir the reciprocation of the plunger 20is effected. By the downward movement of this plunger the overla ped veneers are simultaneously folded wit in the frame 18, so that the projecting edges, which are substantially e ual in length, are upturned simultaneously, t us forming the four sides of the basket. In connection with the movable frame 18 are pins 27, carried by a suitable number of stationaryv arms, and these pins project upwar(lly,so

that as the veneers are depressed within the frame the pins will pierce the two veneers, and thus hold them in proper position for the succeeding operation. y

Any suitable or desired mechanism may be employed for turning the shaft which carries the devices for forming the baskets. I have here shown guide-channels 28, plrojecting'racarries the basket-formers, and these are en aged by a roller 30, mounted upon a cran -arm 31, and this crank-arm is actuated b means of bevel-gearing 32, mounted upon t e countera shaft 33, through" which power is transmitted from the motor. This roller 30 is moved into one of the guide-channels 28 durin the rotation of thearm and movedthrou an arc of a circle which is sufficient to e ect a" uarter-revolution of the shaft, as previously escribed, and being known as the Geneva movement. It will be understood that any equivalent mechanism for producing this quarter-revolution of the apparatus may be substituted for the device ere described. At the end of each" movement thecross is locked in position during a further operation toward the completion of the basket by a latch engaging asshown at 28. The latch 28* engages notches 28 and has a rearward extension, as shown in dotted lines, Fig. 2, and this is engaged by a short crank or cam arms 28, which revolve in unison with the arms 31, so as to lift the latch at the instant when the'roller 30 enters a slot 28and allow the structure to revolve. The basket having been partially formed, as previously dewhich motion is transmitted to advance t e chains intermittently. Thesechains have slots or channels into which the strips 37 are placed. These stri s, which have been previously cut and fdlded into a shape, as shown, are of suflicient length so that each strip will extend along one side of the basket,

and when bent to form the corners its ends will extend a little more than midway of the other side of the basket, so that two strips when bent to encom ass the to of the basket will overlap sufficient y so that t ey may be telescoped and when crimped upon the ed e ofthe basket will form a continuous rigi binding therefor. The carrierchains and their pulleys are in pairs sufficiently se arated, and the V-shaped stri s being lai into the correspondingly s aped outwardly projecting notches, as at 38, will be advanced by the mechanism which advances the chains,- and the upper and lower chains will be ad-' vanced simultaneously so that one strip of metal will be presented from below and one, from above and with their open edges presented toward the top and bottom edges of the basket, which has been turned so as to face these strips. The strips are then bent by a mechanism to be hereinafter described, so as to form the corners, with the endsprojecting and overlapping on the upper and lower sides,

as previously described. The strips are then advanced against the edges of the basket and subjected to the pressure of crimping devices, which'close the open edges of the strips and crimp and indent them into the top edges of the basket, so that they are firmly held in place. The overlapping portions being also crimped together by this operation forms a practically continuous integral binding around the top edge of the basket. The metal strips are respectively carried upon the upper part of the upper chain 34 and by the lower part of the chains 35. supports 35 below this ower chain preventing the strips from falling down. The chains are advanced so as to deliver a-single strip each in conjunction with each quarter-revolution of the basket-carrier. This mtermittent movement is effected b means of hooks, asat 40, which engage with the teeth of ratchets 41 at each forward movement of the devices which advance the previously-placed strips of tin and the crimp- 1ng-jaws, and as the reciprocating movement of these carriers is in unison with the quarterrevolutions of the basket-carriers 18 it will be understood that the strips of tin are advanced and delivered at such times that a binding for each basket will be prepared when the basket arrives at the proper position. The hooks 40 are connected with a cross-head 40 upon the shaft 40 and reciprocated by means of a cam 33 and a fulcrumed lever 33*. Each strip of tin when it reaches the end of its travel by means of the chains contacts with a guide, the upper guide being shown at 42 and the lower one at 42. The next movement causes the notched arms 43 to engage the strips and to advance them to a position in line with the folding-rollers 44. These rollers are carried in the ends of slotted links 45, the opposite ends of which are ivoted to bars, as at 46. The slots in the links are movable over fiXed pins 47, so that when the bars 46 are'moved toward the center the links will slide upon the pins 47, and this will move the rollers 44 inwardly, and as the ends of the stripsof tin project in line with the line of travel of these rollers it will be seen that the .tin will be folded or bent so as to form corners to correspond with the corners of the basket. The folded portions being sufficiently longer than the side of the basket will overlap, as shown plainly in Fig. 17. The strips of tin when first advanced to the foldingrollers pass beneath arms 48, which are actuated by springs, as at 49, and these arms press upon the strips sufiiciently to hold them in position while being acted upon by folding rollers. When the folds have been made, the sides which'have been foldedd'own are s imilarly'held in place by arms, as shown at .51. The position of the strips at this stage is well shown in Fig. 15, the strips then lying between twoguides 51 and 51 and one strip being above. the other. the strips are moved so that the overla pin ends interlock, and this movement is e ecte by the backward movement of the interior chuckor support which carries the interior crimping-jaws. These jaws are well shown at 52, Fig. 16, and are carried upon the intecam-grooves formed in it, and the jaws 52 are uided and slidable radially upon the chuc or support and are moved by means of pins, as at 55, projecting into the cam-grooves of the disk 54. Thus when this disk is turned the. jaws 52 will be simultaneously forced outward a ainst the interior surfaces of the folded strips which have been previously placed upon the edges of thebaskets. At the same time the exterior crimping-jaws, as shown at 56, are simultaneously moved inward by the action of cams 57, operating similarly to those just previously described.

the folded strips firmly upon the baskete ges. This being done, the jaws are retracted, and as the jaws 52 are retracted inwardly they expose strips or edges carried by or forming a part of the chuck 53. These edges project'- just sufficiently to engage-the strl s of tin, and'as the chuck is being retracte after the the ollowing strips, which have alread been bent and folded, and as the following asket arrives in position the chuck will be a ain advanced and will bring the strips toget er,

are afterward-forced upon the edge of the basket, as before described. In Fig. 19 I show diagrammatically the jaws 52 retracted, exposingthe edge orstrip of chuck 53. This edge engages the edge of the outer strip 37, (the strips being in the relative positions shown in Fig. 17, as at No. 1.) 111 said Fig. 19 No. 2 shows the next position with the strips closed. No. 3 shows the parts withdrawn to allow the plate to pass behindthe strips, and N0. 4 shows the plate again projected, so that when it again advances it will engage the strips from the rear and force them upon the edge of the basket when the parts again move'forward. The strips being heldin Fig. 15,) it will be. seen that they will always register, and thus be properly forced together.

These springs act when released to eject the finished basket. i but are prevented from acting during the rlarger part of the revolution of the carrier.

Thus both sets of jaws 52 and 56 will be moved simultaneously to crimp or com ress in place between the guides 51 51, (shown Within each of the frames 18 is a plate 17,

The irregular portion of the cam 63 is extended out beyond the circular portion, so that'the portion 63 when inline with the discharging position of the carrier, as shown at the left of Fig. 5. will allow each roller 64 3 standing at right angles and intersecting at to travel outward, and with it the cross-head 61, which is pressed upon by its spring 62.

This movement acts through the rod 60 to force the plate 17 out, as shown at the left of Fig. 5, and thus eject the completed basket. The next advance of the carrier causes the roller of this cross-head to enter the concaved portion 63 of the cam, and ,this acts to retract the plate 17 a little and insure its pass ing to the vertical position without its edges touching the veneers or moving parts, which are now being brought toward thecenter in readiness to be delivered when this former reaches its position of rest. Before this occurs, however, the cam is turned, as previously described, so that the portion 63 will coincide with the roller 64, and as the plunger forcesthe plate 17 to the bottom of the former-frame 18 against the tension of its sprin s 62 the roller 64 moves along the cam until it reaches the part 63 of the cam, which is substantially concentric with its axis of revolution, and the plate will thus be retained in that place until the carrier has again reached the position of discharge. Be-

tween the concave portion 63 of the cam.

and the incline 63 is a convex portion which acts to move the plate 17 outwardly a little, so that as the veneers arrive in their crossed positions one above the other this outward movement of the plate will press the veneers together and against the bottom of the plungers. A spring 67 acts against a slide 68, movable wlthin the plunger, and the foot of this slide moves the upper veneetr downupon the lower one as the plate 17 is pressed into the former, and thus insures the veneers against, displacement before bending. As the plunger begins to move inward to form the basket the movement of the slide is arrested by a stop, (shown in dotted lines at 69, Figs. 3 and 4,) while the plun er continues (and folds the veneers into t e former 18 sheets of veneer are.
