2' which table and legs may be composed of any suitable material. A motor 12 may be secured toone of the legs as a means for furnishing power to drive the machine, or other suitable driving mechanism may be employed. The power may be applied to a driving shaft 13 as by means of a belt or other suitable connection, said driving shaft being mounted in bearings 14 secured to the back edge of the bed or table 10.

This machine contemplates the manual introduction thereto of. parts and material to constitute the mops or other cleaning implements, and the machine is also so arranged that it is readily adaptable for manual operation to a greater or lesser extent. As here- 1930. Serial No. 460,889.

ly to force a rod resting upon mop material inthe form of numerous threads into aback of trough shape, said material being'folded or doubled as it .isforced into theback. The sides of said back are then closed together to. secure the rod and mop material firmly within said back. 7 f

This mechanism comprisestwo plate levers 15 having their front edges formed, as main jaws, said levers being hinged .at their back edges to opposite sides of an opening extending across the table, said levers being of'corresponding shape each to the other, and of a length at least equal to that of a mop to be formed in the machine. In thestructure herein shown the levers are supported by blocks 16 secured in any suitable mannerjto formopposite edges of said opening in the' table, a pintle or pivot 17. attachingv each levertoablock. .1 End closing jaws 18 are pivotally supported in notches in the edges of the levers 15 near opposite ends thereof, therebeing a pair of end closing jaws near each end of each pair of levers 15, the jaws of the latter being shaped to cooperate with the jaws 18 to close the edges at the ends of the back together, while the main jaws betweenthe jaws 18 are shaped to leave a space between the edges of the back sufficient to contain mop material These plate levers or jaws are so arranged as to be readily adapted for manual or mechanical operation, the latter being shown herein wherein the levers 15 are operated by links 19 pivotally attached to each lever, preferably at opposite sides of the lengthwise center thereof, each link having a guide-stud sliding in a guideway 20 in one of thes'ides 21of an .inverted U-shapedbracket secured to the under sideof the bed 10. roller mounted on each link engages in a cam groove,

in a cam 22 secured to a cam shaft 23-mounted in bearings secured to the edges of the bed or table 10. r r

The end closing jaws'18 have, at their ends opposite the back closing ends thereof, rollers in contact with earns 24 sloping in opposite directions on opposite sides of the top of a cam block 25 supported on ledges on the sides in shown the mechanism is operated manualor plates 21 of the U-shaped bracket hereinbefore mentioned, said cams operating, as the jaws 18 are carried down by the downward and closing movement of the levers 15, to separate the roller bearing ends, thereby swinging the opposite ends or jaws proper toward the main jaws, and cooperating with the main jaws to close the ends of the trough shaped back 26 t hera These trough shaped backs are manually pushed into the grooves between the edges of the main jaws, as shown in Figure 6, and rods 27 comprising the cores of the mops are in a similar manner pushed into a trough extending lengthwise through a rod carrier comprising a head 28 attached at opposite ends to. they lower ends of plungers 29 slidably mounted in brackets30 secured to and rising fr'o'm'the bed or table 10 near opposite sides ther'eofl A rodholding blade 31 is pivotally supported bythe head 28 and has a lip atits lower edge on which the rods 27 rest, as shown in Figures 5 and 6' of the drawings. A plunger blade 32 is'support'edat the-lower end of guide rods 33 slidably' mounted in the bra'ckets 30,both of said rods having toothed racks meshing with'the teeth of plunger actuatinggears 34secured to an actuating shaft 35 manually actuated as by a handle9 The plungers29 are connected with and for operation by the guide rods'33f by plates '36, springs 37 being interposed betweensaid plates and shoulders on the rods'to provide ayielding connection between the parts. The blade 32 extends through slots 38 at opposite ends of the head 28. i i

It will" now be seen that operationof the handle .9 will cause the rods 33 and the blade 32 to beforced dbwnwardly, thereby forcing arod 27 out from the pocket between the head 28'and the rod holding blade 31;. Said rod is forced by the blade 32 against the .tdp

surface of the mass of'mop material 39 extending across the mouth of the groove in the mop, back .26. Movement of the plunger bla'descontinuingthe rod and Iiiop mass are forced into the groove in the mop back, the

rod holdingxblade' 31. having been forced away from theblade 32 to permit the rod 27 to passout of the pocket. When therod's 33 are forced downthey meve some distance independently of the plungers 29 and head 28wl1ile tensioning'ofthe springs 37 takes placerto eventually move the head 28 downwardly against the tension of retracting springs 40 exerting a force upwardly on said head The head 28 is thus'moved against the threadmass, clamping saidi mass between the head, and one of the jaws 18 to hold the mass from backward movement at this point.'- The springs37 are under snflicient tension at this time to hold the head 28in its lowermost position while the blade 32' moves upwardly independently of the head. When the springs 37 are sufiiciently of the drawings.

drawings. A feed actuating bar 43 is connected at one end to the lever 42 by a pivot adjustable lengthwise of the lever to secure a greater or lesser amount of movement of said bar in the swinging movements of the lever.

At its opposite end said bar is slidably mounted in a rest 44depending from abracket 45 secured to and projecting from the under side of the bed or table. A rack 46 is carried by the bar at this end thereof, the teeth ofsaid rack meshing with the teeth of a gear-147 secured to a shaft 48 rotatably mounted in the bracket 45' and having a gear49 secured thereto and meshing with a pinion 50 secured to a shaft 51 rotatably mounted in the bracket 45. The shaft 51 has gears 52'secured thereto at or near'opposite ends, said gears meshing with the teeth of feed racks 53 mounted for sliding movement at opposite edges of-the bed or table and between gibs 54' secured'to the table, and as shown in Figures 1,12, and 3 After each operation of the ma'chinea completed back 55 with the mop material secured thereto is formed, but at first they are all "contained in a continuous length of the mop material. he ends of the back project outwardly beyond opposite edges of the niop strip, as shown in Figures 1 and 3' of the drawings. This stri with the several mop backsliaving the pro ecting ends is extended along the bed for-some distance until said strip is subjected to the action of acutter' that severs the strip into separate niop structures, each comprisinga back with themop material projecting substantially to the same extent on opposite sides of theback.

In the machine shown herein the actual feeding operation takes place near the cutting device and at such distance from the initial forming mechanism hereinbefore described 'forsecuringthe niop material in the backs of tlie strip is in position for its projecting endto be engaged by a pair of feeding latches 56, each memberof said pair being located opposite the other member and being secured to a plate 57 attached as by means of screws to one of the racks 53. 'A' guide strip 58 of angular shape in cross-section to receive and guide the projecting ends of the backs 55 is supported on the gibs 54'as by means ofblocks passing underneath said ends.

59 that are secured tosaid gibs, said strips :overlying said ends. 7

- As the racks are reciprocated in unison with 'the operationsof the mechanism for securing theniop. material to the backs the latches 56 are moved under the projecting ends of the --mop back, said. latches'yielding or moving downwardly against the force of springs and After pass ing said'ends the latches rise under the influence of their springsin position to-engage said projecting ends on movement of the racks in'the opposite direction and thereby .move the strip forward a one-step distance.

convenient points to rails 61 extending on opposite sides of the mop strip and along which'rails the projecting ends of the mop backs are;moved', one of these latches being located at the opposite end ,of a mop strip from another of said latches. They are preferably spring? pressed upwardly and yield downwardly against the force of their springs whenengaged by the projecting ends of the mop backs as the strip is pulled along. The feeding latches 56" are preferably moved to substantially the same extent on opposite sides of and across a cutter slot62 formed in the table.

A cuttermechanism of any desired construction is located to sever the mop material }to complete, the formation of each brush structure, this mechanism, exceptin combination with other parts, formingno part of my present invention. Briefly described, this mechanism comprises a swinging frame having a cutter shaft 63 rotatably mounted thereon and driven as by means of a 'belt '64 from a pulley secured to the driving shaft 13. A

J cutter, of circular type, is secured to said shaft in position to be swung upwardly by the frame through the slot 62 in the bed.

A hood or shield 65 is pivotally mounted at one side of the table projecting thereacross to cover the slot 62. Said hood is connected with the swinging frame hereinbefore referred to by a flexible connection 66 secured at one end to the hood and at its opposite end to said swinging frame, said flexible connection passing around several sheaves, as shown in full and dotted lines in Figure 2 of the drawings. One of these sheaves 67 is rotatably mounted in a lever 68 secured to a shaft 69 rotatably mounted in a bracket depending from the under side of the table, and asshown in dotted lines in Figure 2. Said shaft has an arm 7 0 secured thereto and a cutter actuating bar 71 is pivotally attached to the outer end of said arm. The bar 71 has a guide slot through which the shaft 23 passes, that end of the bar opposite the arm 70 having a'roller in engagement with the periphery of a cutter actuating cam 72 for imparting reciprocatingmovement to the cutter frame and hood in unison with the other operationsof i the machine. Said bar 71 when moved by theeam 72 exerts a pull upon the connection '66, and as the hood orshield 65 offers less resistance to movement than does the swinging cutter frame, said hood is moved do-wnto cover the slot 62, and when it encounters the table-it offers resistance to further movement and consequently the swinging frame beaning the cutter is raised, carrying ,theedge of the cutter through the slot 62 and through the thread mass/severing the outer ends thereof; i i

In the operation of the machine, itbeing assumed that thestrip of mopmaterial has been extended far enough for engagement of the projecting ends of the mop backs with the feeding latches, and the machine being at rest, thehandle secured to -the shaft 35 is rotated, thereby first moving the plunger blade 32 downwardly to force a-rod 27 outof its pocket in the head 28 and against the strip of mop material. After the blade 32 has beenmoved a certain distance the tensionof the springs 37 will become sufticientto move the head 28 downwardly against the strip of mop material toqclamp the latterin place, While the parts are held in this position a clutch operating handle 7 3 secured to a clutch operating shaft 74 is rotated by the operator to effect operation of a clutch andset the machine in motion. 'This starts operation of .the cam shaft 23 that results inthe clamping operation of the strip closing jaws, thereby firmly securing the material in the mop'back. The strip of mop material is given a one-step movement and the cutter mechanism operatesto sever the end of the'strip and produce a mop structure,

The clutch mechanism is of that well known type called a one-revolution clutch,

that is, the cam shaft 23 has onecomplete tion effects one. complete operation of the machine. As the particular structure of this clutch, aside from its being 'a"one-revolution clutch, is immaterial to the present invention, and as it may embody any of the well'known types of one-revolution clutches, only a brief description will be givenherein. Y.

I j The main shaft 13 extends into a housing 7 5 within which the clutch is located. A worm-on said shaftmeshes with 'a worm wheel 77 forming one member of a chain of gearing terminating in a clutch sleeve 78 within which clutch members of semi-round shape in cross section .andof a well known type are located and serve to connect the sleeve 78 with the cam shaft 23. 1 v a, As hereinbefore noted onei operation-of the machine is effected by one rotation of the cam shaft at theend of which the machine comes to rest, the mopstrip having been .inoved one step in position foroperation of the manually actuateddevice. to insert a rod and fold the mop material into a mop back.
