Referring to the drawings, Fig. 19 illustrates a straight side or tub type of basket formed of a mat or web assembled on my machine. The basket I comprises a plurality of fiber (commonly wood) slats or strips 2 whichare first arranged in crossed relation to provide a web or mat and then bent to form the side wall and bottom of the basket. The portions constituting the side wall are held in place by the hoops 3, the parts being secured together by staples 4. The basket which I illustrate in Fig. 19 is of conventional design and forms no part of the present invention. Heretofore, the webs of baskets of this character have been formed by a single operator who arranged the strips in a radial web and then stapled them together at the center. I aim to provide an improved method of and means for arranging the strips to form the radial web, and for stapling the strips together.

My web assembling machine as illustrated in the drawings, comprises an endless chain conveyor 5, and a pair of rails 6, 6 arranged in spaced relation to provide a circuitous track in a substantially horizontal plane, the parts being supported by a frame I. On the circuitous track, I mount a plurality of spaced strip or stave receiving forms 8 which are connected to the conveyor for movement therewith. The forms are preferably detachably secured to the conveyor as illustrated by Fig. 7 so that they may be readily changed if desired. g l As shown by Fig. 12, the forms 8 are provided the swinging stapler head. 2!.

with bearing shoes or plates I 0 which are adapted to slide on the rails 6 and hold the forms in a substantially horizontal position throughout their circuit. In completing one circuit, each form passes a series of spaced operator stations where the forms are loaded with strips 2, stapled together and finally discharged. The forms are charged or loaded with the strips at the various loading stations by operators who place the strips In position while the forms move past the stations,

The conveyor 5 is driven at a constant speed with an uninterrupted motion by the motor I! which is connected to the conveyor by means of transmission 12, chain l3, shaft i4, beveled gear i5, gear Wheel i5, vertical shaft i1, and sprocket IS, the latter directly engaging the links of the chain conveyor. Idler sprockets i9, i9 guide the conveyor 5 around the outer turns of. its path, vertical rollers 21! being used in the corner under The path of the conveyor under the stapler head is the segment of a circle whose center is at the vertical shaft 22 of the stapler head.

Except for the swinging stapler head 2!, the stapler 23 is or may be of conventional design and is therefore well known to those skilled in the art. It will therefore be sufiicient to point out that the stapling operation automatically follows the actuation of thetrigger 24 which is arranged to beengaged by the finger 25 on each of the forms sothat the. strips arestapled together, the last step in forming the web, as the "stapler head travels with the form.

The power for the stapling operation'is supplied by the motor 25 which is connected to the shaft 22 by means of. the transmission 27, clutch 28, brake 29, crank 3i], and connecting rod 3|.

'The motor 26' runs continuously, the trigger 24 being adapted to close the clutch 28 which results in turning the crank 30 around once so as to move the stapler head 2| down and then up, or

through one cycle. In so moving, the stapler head drives a staple 32 through the radial web 33 on the form 8, as illustrated by Fig. 13.

The trigger 24 is secured to the shaft 3 3 and is held in its initial position by the tension spring 35 acting on the shaft through the arm 36. Be-

fore the finger or tappet 25 on the form engages the trigger 2d, the swinging stapler head 2! is picked up by the form and moved therewith;

For moving the stapler head with the forms, I provide each with a depending socket 31 in which is mounted a slide 38 having a lateral arm 39 projecting through a slot 4!! in the side of the socket, Figs. 4. and 6. The slide 38 is urged to its turned to its initial position by the weight d3 which is connected to the arm 42 by means of the cable M which passes over the pulley d5.

The mechanism for releasing the slide 38 from .the arm 32 comprises the stationary cam 45 and the sleeve-like roller 41 on the lateral arm .39 of. the slide.

As shown by Fig. 6, the movement of the form 8 brings the roller 41 into en- .gagement with the cam 46 which acts to elevate the slide 38 above the arm d2, thereby releasing the latter and allowing the weight to return the stapler head to its initial position. As pointed out. above, during the travel with the form, the

stapler head is operated to drive the staple home, this operation being initiated by the engagement of the finger 25 on the form with the trigger 24. The spool 48 of wire supplies the stapler head 2| with stapling material in the conventional way.

Each of the strip receiving forms 8 comprises a concave or dished plate having an annular upstanding flange 49 at its rim. An annular series of pins 50 is arranged in spaced relation to the flange for locating the strips 2 as they are placed in the form by operators at the various strip loading stations. At the first station 5|, the operator removes the previously stapled web and places one strip, preferably bearing a stock number. and/or trademark, in position, as illustrated by Fig. 14. This form then travels past the second station 52 where the second operator lays four more strips of staves in the form, as shown by Fig, 15. The third operator at the third station 53 lays five more staves in the form, as shown by Fig. 16, and the operators at the fourth and fifth stations 5d and 55,- respectively, each add five more, as illustrated by Figs. 17 and 18, respectively. This completes the steps of laying the strips in place in the form, the assembly now being ready for the stapling operation.

As the form fully loaded with staves leaves the last loading station 55 and approaches the stapling station 56, the slide 38 on the form picks up the arm 42 of the stapling head causing the stapling head to travel with the form in proper stapling position while moving. While the stapler head and form move together in this manner, the finger 25 on the form engages the trigger' 24 which results in the operation of the stapler to staple the staves together at the center, thus completing the assembly of the web. The lateral arm 39 then engages the cam 16 as the form advances, resulting in the release of the arm 42 and the return of the stapler head to its ini'- tial position for cooperation with the succeeding form. This completes the cycle of operation of the machine, the operator at the first station removing the completed web and inserting the first stave of another web in the form as described above.

The forms are concave to allow for the thickness of the superimposed strips arranged in crossing relation at the center, the'top layer being substantially flat or level for proper coaction with the stapler. The forms are readily removable from the assembly so that they may be replaced by similar forms of different sizes, the arrangement being such that the change'can be made in a comparatively short time for the whole machine, or the forms may be adapted for smaller baskets as shown in Fig. 20.

In my machine, the forms move continuously in a circuitous path and are thereby made capable of being filled with stock in an orderly manner and the stock stapled together while in motion. Each operator Works while the forms move past his station and thus the webs are assemsembled at a predetermined rate. The track may be extended to provide more operator stations and the capacity of the machine thus increased.

In Fig. 29, I show'one of the forms 8 provided with an auxiliary form 51 which comprises an annular ring having an upstanding flange 58 at its rim and an annular series of pins 59 spaced inwardly therefrom, the flange 58 beingadapted to fit ,within the pins 5%) of the form 8. Thus, the form is adapted to receive shorter slats for mak-- compared to the full bushel size'for the regular 7 form a. By virtue of the auxiliary form 51, the

machine may be quickly adapted to make thesmaller sized Webs without removing the forms 8 from the conveyor.

From the above description of my invention, it' will be apparent to those skilled in the art that I provide a web assembling machine which is simple and economical in its parts and efiicient and effective inoperation. The machine is capable of assembling a large number of webs in a com paratively short time and in this respect it is much superior to the method commonly employed prior to my invention. While I have found the use of five stations in connection with five forms which travel in a path of the character set forth highly satisfactory, it is to be understood. that any number of stations may be employed with any number of forms which travel in any desired path, so long as the path is circuitous and each form returns to its initial potition upon completing the assemblies and stapling of the webs.

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:
