Application filed August 27, 1914. Serial No. 858,808.

To all whom t may concern:

Be it known that I, JOHN S. McCHEsNnY, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Broom-Filler-Assembling Machines, ,of which the following is a full, clear, concise, and eXact description, reference beinghad to the accompanying drawings, forming a part of this specification.

My invention relates to the manufacture of brooms and has for its general object the provision of a broom filler assembling machine whose purpose is to permit the ready application of previously formedbands to bundles of broom straw. The machine of my invention is of particular service in preparing bundles of broom straw with encircling bands which are subsequently to be subject to `a collapsing operation that is preferably eifected by a distinct mechanism but to the employment of which distinct mechanism the invention is not to be limited.

In practising my invention I employ a chuck for eiecting the initial assembly of broom straw into Aa bundle and having a portion of its wall, arranged to be opened and closed, the chucky wheny closed permitting the broom bands to be alined there-- with in position to enable thepassagetherethrough of the buttl enddof a bundle of broom straw, the chuck being `opened after the bands or rings have been. positioned about the broom straw to permit of the transfer of the banded straw to another machine where the bands kare Lcollapsed into `permanent clamping engagement with the 40.

straw, the resulting product being a permanently assembled bundle of straw itself forming a broom or capable of being combined with a handle to produce ahandled broom.

In practising my present invention I employ mechanism for feeding or permitting movement of the bands into alinement withr the chuck; mechanism for opening and closing the chuck; and actuating mechanism common to the aforesaid mechanisms and serving to operate the same in orderly sequence. The actuating mechanism which I prefer to employ is one that includes an operating treadle `but I do not wish to'be limited to the source ,of ,power nor to the the mechanism illustrated inV Fig. l; Fig.

4 is a sectional view on line 4 4 of Fig. 7 g

Fig. 5 is a perspective view of a partiallyV formed product as it leaves themachine of the invention preparatory to aband collapsing operation; Fig. 6 is'a view on line 6 6 of Fig. 7 Fig. 7 is a view on line 7 7 of Fig 6; Fig. 7 l is a detail illustrating the positions of some of the parts as they appear in Fig. 7; Fig. 8 is a view on line 8 8 of Fig. 9; and Fig. 9 is a View on line 9 9 of Fig. 8.

Like parts are indicated by similar characters Vof reference throughout the different figures. l

The broom straw is preferably temporarily assembled by hand in quantities just sulicient to constitute the desired brooms.

The manuallyassembled bundles of straw 5 which margin a Lgroove 6, there being thus V two grooves 6 which are angularly separated, the bottom ring `in each vertically alined pile of rings resting upon the top surfaces of the ledges 5 margining the groove 6 individual to such pile. The top surfaces of the rear pair of ledges 5 are in the same plane with the bottom of the upper space or groove 2 while the top surfaces of the remaining pair of ledges 5 are in the same plane with the Vbottom of the lower space or groove 2. i

A pusher 7 is individual to each groove 2 and slides upon the ledges 5 also individual to such groove. yThese pushers 7 are designed for simultaneous operation and in their outermost positions are behind the rings that rest upon'the ledges 5. As these pushers are thrust inwardly they carry with them the lowermost rings from their places beneath their magazines, the pushers in their innermostpositions placing these ringsV in alinement with the bore of the chuck (now closed), the rings entering this position by passing throughv the grooves or openings 2 in the chuck. After a pair of rings are thus 4alined with the chuck, a previously gathered bundle of straw, which is of sufficient amount to form the desired broom. is passed down-V wardly, butt end lirst, through the bore of the chuck andthe two rings which temporarily take part in defining the bore of the chuck; After the butt end of a bundle of straw Vhas thus been passed through a pair of ringsthe chuck is opened, aV half 11 of the chuck being in hinged connection with V.the remaindenas indicated most clearly in Figs. 3,7, 7, S and 9. After thechuek has been opened the banded bundle of straw may be removed to be subject to the opera-Vv tion of a ring collapsing machine to bring about a permanent assembly of the straw.

VIn accordance with my present invention the operation of the pushers and the opening and closing of the chuck are so ,relatively timed that these operations are bound to occur in predetermined and fiXed order and to this end I prefer to employ the formkof mechanism now to be Vspecifically described.

f The power for" operating the machine is desirably applied by the foot ofthe operator tothe treadle 8 having a xed fulcrum at 9 and. connected at an intermediate portion thereof 'with the lower end of link 10 that is pivotally vconnected at its upper` endwith a collar 11v arranged to slide vertically upon upright guide rod 12 whose upper end carries an adjustable catch 13 that defines the extent to which the butt end of abundle of straw lmay be inserted within the chuck 1; A spring 14, surrounding kthe guide rod `12, serves normally to position the treadle Vand collar in the locations for these elements illustrated in Fig. 1.Y Levers 15' (each inv, n dividual to a pusher 7) are fulcrumed at their lower: ends and carry rollers 16 at their upper ends which are received between the ,sides of forked lugs 17 that are secured to the bottoms of the pushers 7 Intermediate portions of the levers 15 are connected'by ,links 18 with the sleeve or collar 11 whereby the levers 15 are moved outwardly when the treadle is depressed against the force of the springlctoposition the pushers 7 to the rear ofand in line with the lowermost bands 3 that'are restingV upon the pairs of ledges 5 that areV individual to the vertically alined grooves 2 and also to open the chuck. VVhen y,the treadle s released. the spring 14:, in restoring the parts to the positions illustrated in Fig. 1, forcesinward movement of the pushers 7 whereby two rings vare removed from the region oftheir magazines into alinement with the bore of the chuck as illustrated most clearly in Fig. 6, the chuck being also closed during this inward movement of the pushers. Y

VThe swinging section 11 of the chuck is provided with a crank arm 19 to which motion may be imparted Athro-ugh pitman mechanism that isoperatively connected at one end with the outer end of the crank 19 and at its other end with the rear one of the two levers 15. Vhen therear pusher 7 thatl is individual tothe rear lever 15 is moved n inwardly upon the inward movement of this lever the crank 19 is turned to close the section 11 of the chuck 1, this closure beingVK desirablyV completed before both bands which are being pushed by` both pushers have been finally positioned in alinement with the bore of the chuck. In order that the chuck may be closed before the two rings are valined therewitlnthe pitman mechanismv preferably includes'a rod 20 free to move within the bore of a cross heador guiding sleeve 21 carried vupon the rear lever 15 by means of a universal joint 22. The

' cross head sleeve 21 is disposed between col lars 28 that are yadjustably fixed' upon the Vrod 20, springs'2il and 25 being located be f tween the sleeve 21 andthe collars 23 as indicated most clearly in Fig. 9. As the rear Vlever 15 is `moved inwardly causes the sleeve 21 to press upon the spring 25, the pressure thus exerted being transmitted through the forward collar 23 and the rod 20ito the, crank arm 19 whereby thesection Y 11 of the chuck is ultimately closed. The closure of thechuck, however,Y is completed before the levers 15 haveAV been moved to their a innermost positions, continuedfinward movement of the levers V15 beingV permitted, in order'to place the two rings in alinement with the closed chuck, byy means yofthe spring 25 that will then yield sufficiently for this purpose. The chuck section 11 having been closed before the rings arelocated within'the chuck, means may bejemployed whereby the front pusher 7 maybe brought into position to hold the. chuck closed'when the inward movements of the pushers have beenycompleted whereby the closure ofthe chuck is so firm that the subsequent insertion of a bundle of broom straw will not Vopen the chuck whereby the alinement 0fA -the broom bands with the bore of the closed 'chuck cannot be disturbed whilea bundle of straw is being inserted within the closed chuck, it being assumed that the treadle isV in its released position, it being understood: that it snecessary to release the treadle in.VV

orderto permit theV spring 14 to move the Vpushers inwardly to close the'ohuck. The

l action of the chuck which is effected by the pressure of the sliding collar or cross Yhead 21 upon the spring 24, the pressure being transmitted from the spring 24 through a collar 23 to the rod 20. TheV chuck is Opened when the lug 28 engages the stop 29, this engagement occurring before the pushers 7 are in their rearmost positions. Continued movement to the rear, after the complete opening of the chuck, is permitted by the spring 24 which may be further compressed after the chuck has been completely opened to permit of the further rearward movement of the levers 15.

It will thus be seen that I have provided mechanism whereby the opening and closing of the chuck is timed to occur in proper relation to the forward and rearward movement of the pushers and while I prefer to employ the mechanism illustrated for Aaccomplishing this result I do not wish to be limited thereto as changes may readily be made without departing from the spirit of the invention.

`While I prefer to employ means for feeding two bands to the chuck I do not wish to be limited to the feeding of a plurality of bands to the chuck at a time, it being obvious that my invention is capable of use when one or more bands are to be fed into place.

Having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. A broom filler assembling machine including a chuck for effecting the initial assembly of broom straw into bundles and having a portion of its wall arranged. to be opened and closed; mechanism for eecting the feeding of bands into alinement with the chuck; mechanism for opening and closing the chuck; and controlling mechanism common to the aforesaid mechanisms to effect their operation in orderly sequence, the mechanism for opening and closing the chuck including a crank arm connected with Copier ef thin the movable wall portion of the chuck, la, y p cross head moving with the band feeder, a

pitman rod with respect to which the cross head is movable, and springs interposed between the cross head and portions fixed uponr the pitman rod, one spring serving to permit closure of the chuck before the bands are fed into position and the other spring permitting opening of the chuck before the band feeder has been completely withdrawn.

2. A broom filler assembling machine including a chuck for eecting the initial assembly of broom straw into bundles and having a portion of its wall arranged'to be opened and closed; mechanism for effecting the feeding of bands into alinement with the chuck; mechanism for opening and closing the chuck; andcontrolling mechanism common to the aforesaid mechanisms to effect their operation in orderly sequence, the mechanism for opening and closing the chuck including a crank arm connected with the movable wall portion of the chuck, a cross head moving with the band feeder, a pitman rod with respect to which the cross head is movable, and springs interposed between the cross head and portions fixed upon the pitman rod, one spring serving to permit closure of the chuck before the bands are fed into position and the other spring permitting opening of the chuck before the band feeder has been completely withdrawn, the feeder carrying a portion which is brought into position to maintain the chuck closed when the bands are fed into place.
