Figs; 9' and 1 0 are sectionalelevations of the mop fiber and handle brokenaway, to show the manner of securing the head of the mop to the handle.

The numeral 5*desi gnat'es a bed or table of suitable dimensions and haviiig" a' s'lot 5 extending inwardly from the front edge thereof a suitable distance; Thebedortable 5 has supporting legs 6 connected by transverse braces 7. Rising from the rear per tion of the bed or'table 5 is a vertical frai'ne consisting of parallel spaced upri hts 8' hav ing bracket plates 9 secured to the front and rear sides thereof and provided with lower flanges 1 0 bolted or otherwise secured to'thebed' or table 5. Extending. forwardly from the vertical frame between the uprights 8 are upper intermediate and lower supporting arms"1'1, 12 and 13, each essentially comprising parallel" plates orst rips 11 on the upper end of the vertical frame wire guide is mounted; comprising radially disposed arms 14 having rollers 15'- in their outerextremities; between which the wire 16 is passed for regularly fe'eding downwardly over the front portion of the ma chine. The parallel plates or strips 1 1 of the arms '11, 12 and 13 embrace and are secured to an upright fixed guide shaft 17-, which terminates at its uppenend coincidently with theupper'ed'ges-of the plates or strips 11 of'the upper arm' 11 and at its lower extremity coincidently with the lower edges of the plates 11 of the lower arm 13. On the left sides of the arms 12' and 13 a guide rod or strip 18 issecured and thereon is adjustably mounted a check 19" andatrip 20, the said check and trip being held in their adjusted positions by rear' set-screws 2-1 and 22 which bind against the rear edge of the guide rod or strip 18. The che 'cli 19 projects forwardly and has a downwardly directed, angular terminal 23,.the lower edge 24 of said check being horizontally straight.

The trip has a slidable trip nose mounted in the forward extremity thereof and provided with a downwardly tapered face 26,'for convenience in passing the same. The trip nose 20 has a pin 22 extending therethrough and engagin opposed slots 28 in the sides of the forwardly projecting extremity of the said trip, a spring 3 being till mounted in the rear of the trip nose25 within the trip 20 so as to always maintain. said trip nose in normal forwardly projected position.

A clamp is mounted on the lower arm 13 below the trip 20, the said clamp consisting of a forwardly projecting arm 29 having a slot 30 extending through the forward end thereof and communicating with a vertical bore 31 located at a distance inwardly from the outer end of the said arm 29. Extending transversely through the outer end of the arm 29 is a shaft 32 having a cam 33 fixed thereon and operating in the slot 30, the lefthand end of the said shaft 32 projecting outwardly beyond the adjacent side of the arm 29 and having a trip wheel 34" fixed thereon and formed with radial arms 35 adapted to be struck by the trip nose 26 and the forward angular depending end 23 of the check 19. The cam 33 is clearly shown in side elevation by Fig. 3 and is eccentrically mounted. so as to projet the greater portion thereof at one side of the shaft WVithin the bore 31 a clamping means is mounted and consists of two semicylindrical clamping members 34 held in place by a lower tubular screw nut 35, the said members 34 having opposing grooves 36 in their straight sides. The clamping members 34 are shiftable, one towards the other, within the bore 31, the upper part of the said bore being reduced, as at 37, and in alinel'nent with an upwardly projecting guide tube 38, extending to and through a projection or blo' k 39, which disposed above the arm 12 and has a bore 40 extending vertically through the inner extremity thereof, in which the. upper end of the tube 33 is secured. The projection or block 39 has its rear end attached to the upper extrem t of a rack 41 with teeth 42 in its rear edge, the lower end of the said rack being secured to the rear end of the arm 29 of the clamping means.

Depending from the lower side of the inner extremity of the lower arm 13 is an angular guide foot 43, which is held in fixed position by securernent to the said arm 13 and has at its inner end a vertical guide bore 44 and a horizontally disposed die block 45. Rising from the inwardly projecting horizontal member 43 of the foot 43 and in alinement with the bore 44 is short ver- .tical guide tube 46, with which the lower side of the tubular nut is adapted to leg ister when the clamping arm 29. is lowered,

cutter bore 47 extends rearwardly through the rear side of the horizontal member 43 to the guide bore 44, and in this bore 47 is a cylindrical cutter 48 of the form shown on an enlarged scale by Figs. 6, 7 and 8. The forward end of the cutter 48 is forwardly reduced by equally tapering the upper and lower sides 49 thereof between guards 50 having front blunt ends 51 adapted to bear against the inner end of the die 45 and pre vent the cutting edge 49; of the cutter from being crushed or dulled by forceful contact with the said rear edge of the cutting die. The cutting die is removably held in the forward extremity of the horizontal member 43 of the foot 43 by a wedge pin 45", as clearly shown by Fig. 6. The bore 44 continues down into a slotted guard 52 formed as a part of the lower side of the horizontal member 43 of the angular foot 43, to facilitate removal of the severed portions of the.

wire in a downward direction and also to assist in producing a hooked terminal at the upper extremity of thesevered portion of '1 the wire depending from the said horizontal member 43. block or boss member 53 is secured to the rear side of the angular foot- 43 close to and below the lower edge of the lower arm 13, the said block being provided with a rearwardly projecting fulcrum support 54 in which is intermediately fulcrumed a link 55 having a lower extremity depending below the said support 54 and connected to a head 56, in which the rear end of the cutter 48 is secured, as shown by Fig. 3. The upper extremity of the link 55 is connected to the forward end of a coupling link 57 which in turnhas its rear end attached to the lower portion of an operating lever 58, fulcrumed at its lower end to the arm 13, the upper end of the lever 58'being provided with a handle or grip 59.

Below the wire cutting mechanism a suitable distance and mounted inforward and rear bearings 60 and 61 is a rotatable and longitudinally slidable rod or stem 62, having attached to its rear end at a suitable distance from the rear edges of the uprights 8 an angular counterbalancing arm 63. The bearing 60 rises from the table or bed 5 in advance of and centrally disposed with relation to the space between the uprights 8,

and the bearing 61 is mounted and held between the said uprights adjacent to the front edges of the latter. The rod or stem 62 continues in advance of the bearing 60 and'has an upwardly diverging or flaring slot 64 at its front free end extending downwardly to a horizontal web 65, the slot 64 having outwardly curved upper edges 66. The lower extremity of the wire from the horizontal member 43 of the foot 43 immediately above the position of the rod or stem 62 is inserted downwardly in the slot 64. On the rod or stem 62 at a proper distance isfixed a cam sleeve or cylinder 67, having therein a spiral groove 68 and-providedat opposite ends with flanges 69 and 70, to respectively bear against the rear side of the forward bearing 60 and the front side of the adjacent bracket plate 9, the latter and the rear similar plate being vertically slotted as at 9 to permit the rod or stem 62 to operatively pass therethrough. A slide collar 71 is mounted on the cam sleeve or cylinder 67, and in an upper, vertically extending opening 72 thereof is mounted a screw-threaded plug 73 having a depending pin 7 4, which is always held projected in the spiral or cam groove 68 of the'said cam sleeve or cylinder. Secured to the upper portion of the slide collar 71 is the forward end of an operating rod 75, which extends through an opening 76 in the upper portion of the rear bearing 61 and has free'sliding action in an upward and rearward direction in the'saidbearing. The rod passes through the upper portion of the slot 9 in the front bracket plate 9, and to the rear end of the said rod 75 the forward end of a link 77 ispivotcd, the rear end of said link being also pivoted to the lower arm 78 ofan operating lever 79 fulcrumed in a bracket 80 secured to the rear portions of the uprights 8. The levers 58 and 79 respectively have springs 58 and 79' attached at one end of each to said levers, the forward extremity of the spring 58 being secured to the arm 13 and the upper extremity of the lever 7 9' being secured to one of the uprights 8. The lever 79 has a grip or handle 81 at its upper end for convenience in operating the same. The rod or stem 62 with the operating mechanism therefor as just explained constitutes the wire bending mechanism which functions in the formation of the hooked loop'at the lower end of the wire, as shown in dotted lines by Fig. 3, and also assists in properly guiding the wire.

Mounted 1n su1table' bearings 82, one of which is clearly shown by Fig. 2, secured to or between the legs 6, is a shaft 83 on which is mounted a treadle wheel consisting of opposed-heads 84 connected at regular intervals by rods 85. i

The heads have radial arms 84 extending from central webs 8 1 to the peripheral rings 8 1 thereof, and the said treadle ring or wheel 84 is free for forward and rearward, partial rotary movement with the shaft 83 either through pressure of the foot or pulling and pushing action of the hands of an operator. However, this is but one convenient means for operating the shaft 83, and'in some instances it may be desirable to actuate the said shaft through readily controllable power means to which the shaft may be connected. A vertical shaft 88 is mounted in a lower bearing bracket 89 secured to the one cross: brace 7 and also through an upperbearing projection 90- connected to the upper arm 12. The shaft 88 has a beveled gear 91 on its lower end which is held in continual mesh with a beveled pinion 92 fixed on the shaft 83 adjacent to the said gear, and: on the upper extremity of the said shaft 88 is fixed a beveled pinion 93, held in mesh with a beveled gear 94 on a transverse shaft 95, extending through the members 11 of the upper arm 12,.the said shaft 95 having a pinion 96 fixed thereto and rotatable therewith and held in con"- tinual mesh with the teeth L2 of the rack 41 for raising and lowering the upper guide 39 and the arm 29 of the wireclamping mechanism including the shaft 32 and cam 33 which cooperates with the clamping members 34. By means of this mechanism the parts of the improved machine just referred to may be readily controlled as to their elevated and lowered positions during the several steps of feeding and applying the wire to mop heads and sticks or handles;

Preliminary to' threading the wire 16 through the parts of the machine, the adjustably mounted check 19 is positioned at a height required to permit enough wire tobe carried down for application to the mop handle and strands and to insure that the wirewill be in an expandedcondition. The wire 16, from a suitable source of supply such as a reel located adjacent the machine,

is then threaded between the rollers 15 of the arms 14 and passed down through the projection or block 39 into the tube 38, between the clamping members 34 and downwardly through the tube 456 and then through the bore 4% and also into the forward slot 65' of the working extremity of the spindle or stem 62 of the bending mechanism, when said stem has been projected into operative position as shown by Fig-(3;. The spindle or stem 62 is disposed as shown by Fig. 3, by first moving the lever 79 from the extreme forward position shown in dotted lines by Fig. 3 to the second or full line position, this latter movement of the lever bringing the "lower extremity 78 forwardly and through the link 77 likewise moving the rod 75,; which acts on the collar 71 and pushes the cylinder having the cam groove 68 with the said spindle forwardly until the front flange 69 of the cylinder strikes the.

rear side of, the bearing 60. During this movement of the cylinder 67 and spindle 62 through the medium of the collar 71, the pin 74: simply has a forward pushing oper-- ation, in view of the fact that there is no resistance to the sliding movement of the ill) cylinder with the groove 68 until the front flange 69 engages the bearing 60 as just specified, and as a consequence the upwardly diverging slot 64.- and. horizontal web 65 will.

be directly under and in proper alinement with the bore 44 ofthe cutter mechanism above. The lower extremity of the wire threaded through the parts of the machine will also be passed into the slot 64 a sufficient distance to form a hook on the lower end of the wire. The lever 7 9. is then pushed. fromthe full line position shown in Fig. 3 in a rearward direction until it reaches the maximum rear position thereof as shown by dotted lines in Fig. 3, this further movement of the lever 79 causing the collar .71 to slide forwardly over the :am cylinder 67, in view of the fact that the limit of forward adjustment of said cylinder-will be reached when the flange 69 thereof engages the rear side of the bearing (50. This further movement of the lever, therefore. causes the collar 71 to slide forwardly and the pin 74. to move in thecam groove 68 and partially rotatethe cylinder 67 and cause the spindle ($2 .to similarly rotate and bend the lower extremity of the wire 16 to form the hook 16, as shown in dotted lines by Fig. 3. During .thisrotation of the spind e 62, the angular arm or counterbalaucing device 63 is elevated, and after detachment of the hook from the forward working end of the said spindle the latter is reversely rotated'by the gravitating movement of the angular arm or counter-balancing device 63. and the pin 74 moves in a reverse direction in the cam groove 68 of the cylinder 67 and at the same time the groove 64 at, the for ward extremity of the spindle 62 is restored to normal position ready for a succeeding similar operation. or the formation of a hook on the lower extremity of the wire. After the hook 16 has been formed on the lower extremity of the wire, the lever is pulled forwardly a suflicient distance to cause the collar 71 to engage the rear flange and move saidcylinder rearwardly and the spindle 62 in a similar rearward direction to clear theta-ble directly under the bore 44 in the horizontal member 43 of the foot43. The handle it with the mop strands in appplied thereto as shown by Fig. 9 is then brought in position over the slot 5" of the table 5 and the lower portion of the wire with the hook extremity is looped around the mop strands close to and above the usual pin or nail n driven through the end portion of the handle, and the hook 16 caught around the wire above the handle and mop strands shown by Fig. 1. The treadle wheel comprising the opposed heads 44 C'OTlDQCi'Gd at regular intervals by the rods 85 then kicked forward by the operator and the clan'ipingmeans including the clamping members 34 is moved upwardly a suilicicnt distance above the upper end of the tube 46 to draw the wire tautand at the same time the partially secured mop strands are elevated. with the handle. the upward movement of the clampmg means being effected through the rack bar 41 by the gearing including the vertical shaft 88, as heretofore explained. The clamping mechanism is then moved" to a higher position for actu ation by the trip nose 25, which engages one of the arms 35 to release the clamping members 34 as shown in the upper dotted position of the clamping means in Fig. 3. This further upward movement of the clamping means permits the wire to slacken and the operator gives the partially secured mop strands and mop handle a short upward movement, which produces a second hook 16 in interlocking relation to the hook 16, as shown by dotted lines in Figs. 9 and 10, and the wire immediately above the second formed hook 16 is severed by operating the cutting mechanism including the cylindrical cutter 48 and the die 45 through the medium of the lever 58, which is forced rearwardly against the resistance of the spring 58". After the wire is severed, the mop strands and handle are removed and the two interlocking hooks 16 andl6" given a shar blow with a hammer, to com lete the insi e fastening of the mop stran It will be under.- stood that when the lever 58 is released, the spring 58 will return the same to normal position and draw or slide the cylindrical cutter 48 rearwardly into normal position to clear the bore 44 for subsequent movement therethrough of the wire 16,.as in the. preliminary threading of the wire hereinbefore explained, when the mechanism will then be in condition for a repetition of the sameoperation. After the mop strands at the head thereof have been partially secured to the mop handle above the pin or nail a, securement of the said strands is completed by turning the same over the inner wire fastening loop Z as shown by Fig. 10, and an outer wire look Z is applied over the upper or head end of the strands below the pin or nail n, to thereby prevent slipping of the mop head on the handle 6. A number of the mop strands and. handles may be first primarily assembled as shown by Fig. 9 and subsequently the mop strands will be turned over the adjacent lower end of the handle ii. and each secured by the outer loop Z by the same operation heretofore ex, plained in connection with applying the inner loop Z. When the mechanism is arranged for each succeeding operation, or to apply the wire loops relatively to the mop head extremity of the mop. strands, the lower treadle Wheel including the heads 84 and connecting rods 85 will be moved in a forward direction to lower the clamping members 34. and move the rack bar 41 downwardly throu 11 the mechanism heretofore described and properly dispose the wire through the tube 46 and angular foot 43. \Vhen the arm 29 of the clamping means is elevated its full extent, the upper edge thereof contracts with the lower straight edge 24; of the check 19 and the outer depending angular end or terminal 23' of. the said check engages one of the arms 35 of the wheel 34: to cause the clamping memhere 34 to tightly engage vor grip the wire passed therebetween.
