Macrame r03 MAKING TOGGLES.

To all whom/if may concern:

Be it known that I, HERBERT S. CROM IE, a citizen oft-he United. States, residing at- Woburn, in the county of Middlesex and trade is a device which is used tosupport hides during the proc 's o manufacture in which the hides are coa e with some preparation, such as a patent leather preparation, and are then allowed to remain exposed to the air for a suiiicie-nt time tocure or dry them. To suspend the. hides in a horizontal position whilethey are being coated withv the patent leather preparation and while they are afterward drying, a frame is used fromwhich the hides are suspended by means of saidtoggles. The toggle itself consists of a-c'ord fastened to a short bar of wood, usuall rectangular in cross section, and the cord 1s assed through.

- the h de near the edgethereo and the small bar of wood is pulledup against the under side of the hide, which, it will be understood, has to be suspended in a horizontal position and the'cord then passes from the hide to the horizontal surrounding framework. This framework has large headed tacks driven therein and the cord is passed around one of these tacks -and then the tack is driven down against the cord to bind it or look it to theframe-I? A series of these toggles is used on each side of the hide or skin which it is desired to-ttfeat-as hereinbefore set forth. A very large numb r of these tog les is used daily and they can only be use o'nceor twice, as the patent leather preparation has a deleterious effect upon a cord.

Hitherto, these toggles have been made by hand-that is, the'cord has been, usually tied to the bar of wood by hand: ,This' makes the toggles expensive and theriteni of toggles to a manufacturer is quite a large one on account of the enormous number which is used and, therefore, it is thigobjeet of tltis invention to manufacture'sar -jioggles' Specification of Letters Patent.

In the drawings which I shall now proceed to describe specifically, it will be understood, in general, that the bars of the toggles are placed in mass in the-machine and are arranged by suitable mechanism so that they can be taken one by one and presented to the cord which is tobe subsequently attached to them. The cord is manipulated bysuitable machinery so that the same extends around three sides of the bar and while being held in this position the staple is driven through the bar until the closed end engages the cord on one side, and on the opposite side of the bar the legs of the staple project through and are then folded over toward each other in engagement with the cord, passing said cord firmly against the bar. The cord "is drawn out from its holder at one side while it is being held and fastened to the bar to form a long loop, then the side of this 100 farthest removed from the bar is cut 0 freeing the cord which is attached to the bar from .the main portion of the cord in the. machine, and the toggle is then removed.

from the machine. There is an automatic wire feeding and staple forming mechanism the mechanism andcourse of procedure by which the toggle is manufactnred in the Fig. 19 is a sectional nism; 2d, a cord manipulating mechanism;

8d, a staple forming mechanism; 4th, a staple feeding and driving mechanism; 5th,

a cord measuring mechanism; 6th, a cord cutting mechanism; 7th, a toggle ejecting mechanism.

The different mechanisms hereinbefore referred to are operated by a clutch pulley 1' which is thrown into and out of engagement with the main driving shaft 2 by a clutch lever 3 (Fig. 1). The main driving shaft 2 is journaled in suitable bearings 4c, 4 in the frame 5 of the machine (Fig. 3). Said main driving shaft hasa number of cams directly fastened thereto and has a gear 6 fast thereto which is connected by the sprocket chain 7 to a sprocket gear 8 fast to the cam shaft 9.. Said cam shaft t) is journaled to rotate in bearings 10, 10 on the frame of the machine. A bevel gear 11 is fast to the main driving shaft 2 and meshes into another bevel gear 12 fast to a shaft 13 which extends rearwardly from the shaft 2 and operates the bar feeding mechanism.

Bar feeding mechanism, (Figs. 1, 2, 7 and 8.)-Referring, now, to Figs. 2 and 7, the bars 14' to which the cords are to be fastened to form the completed toggle are placed in mass upon an endless belt or apron'15. Said apron extends around drums or pulleys 16, 17 which are connected by the endless belt 15. The pulley 16 is fast to a shaft 18 which is rotated by the shaft 19 to which it is connected bya universal joint 20. The shaf 19 is rotated by mechanism illustrated in Fig. 8, consisting of a gear 21 fast to said shaft 19 and meshinginto a gear 22 fast to a shaft 23. The gear 22 is driven by an intermediate gear 23 which, in turn, is driven by a gear 24 fast to the shaft 13. The carrier belt: or apron 15 is moved by the mechanism hereinbefore described in the direction of the arrow 0 on the advancing side thereof. and the raceway 24, into which the toggles are fed from the carrier 'belt 15, which raceway is clearly shown in cross section in Figs. 7 and 8 and in plan view in' Figs. 1 and 2, extends at an angle to the endless carrier belt 15, the entrance of the raceway be inning at the edge 25 of the belt 15 (see Fig. 2), the upper surface of the ad- The bars belt 15, causes said bars arm 34 which guide 26 and said guide, together with the to move diagonally across the belt 15 and into the raceway 24 end to end. Any of the bars which do not enter the raceway are forced oil of the belt 15, partly by the belt 15 and partly by the auxiliary guide plate 28, and fall onto a suitably arranged chute 29 which extends downwardly between the advancing and retreating sides of the carrier belt.15, so that the bars which fall onto said chute are directed back onto the endless belt 15 upon the upper face of theretre'ating side. Thebars which are returned to the belt are carried in the direction of the arrow 03 against a guide 30 which extends at an angle to the. apron 15 and terminates within a hopper 31,

0 that all ofthe bars which are carried back onto the lower side of the belt are guided by' said guide 30 into the hopper 31. The hopper 31 has an intermittent rotary motion' imparted thereto by a pawl 32 and ratchet 33 (Fig.7).

The pawl32 is pivoted to an is pivoted to a shaft 35 and has a rocking motion imparted thereto by a link 36 which is actuated by a rocker armand which, in turn,

, been started into which has at its lower end a to the frame of the machine is'rocked byan arm 39 which receives its rocking movement from an eccentric rod 40 mounted upon and oper" ated byan eccentric 41 which is fast to the shaft 18. Thus a step by step rotary motion Said hopper 37 pivoted at 38 hopper is rotated, pick up the bars from the bottom of the hopper an spill them onto a chute 43 which extends downwardly from V the upper portion of the hopper toward the upper side of the conveyer belt 15, so that bars which have been carried into the hopper in the manner hereinbefore described are returned by said hopper from the lower side of the belt to the upper and advancing side of the belt. If desired, the bars 14 ma be placed upon the carrier belt itself, or they may be placed in the hopper 31 as may be most convenient. After the bars 14 have the raceway, as hereinbefore described, they are pushed along said as the raceway, end to end, to the front of the machine by a series of rotary feed fingers 44, 44 (see Figs. 1, 2, 7 and 8). These rotary feed fingers 44, 44 are arranged in pairs and g each of said pairs of. rotary feed fingers are pivotally and yieldingly mounted, respectively, upon rotary supports 45, 45. The rotary supports 45 (see Fig. 8) are'each fastened to the upper end of a vertical shaft 46 bevel gear 47 meshing into a bevel gear 48 fast to the shaft 23. Thus a rotary motion is imparted to each of the supports 45 and upon each of these supports 45 is pivotally mounted apair of feed fingers 44. .Each of the fin ers 44 is pivoted at 49-to its respective 'hol er and is held against a stop by a spring 50, so that:

fingers 44 come as the supports 45 rotate the into contact with the bars which are located in the raceway 24, said fingers projecting through-a slot 51 extending longitudinally of said raceway, and bearing against the side of the bar. it will be seen that the springs 50 will yield and thus allow the fingers 44 to move along with a sort of dragging movement to feed the bars longitudinally of the raceway 24 end to end. It will be noted that the rotary supports 45, 45 are set at different angles so that a finger of at'l'east one pair of feed fingers will be in contact with the bars in the raceway at all times during the operation of the machine. The toggle bar's, then, it will be understood end toend in the raceway 24 until the first toggle bar 14 in'the raceway arrives at the position illustrated in Fig. that is, with the front end of the bar 14 hearing against a stop 52. It will be understood that at this time the feed fingers are pushing on this series of, end to end arranged toggle bars, so that the toggle bar 14 is held againstthe stop 52 in the position illustrated in Fig. 4 by this end pressure. raceway, beneath thetoggle bar 14", is an opening 53 of substantially the length of one of the toggle bars and beneath this opening projects the front end of the movable support- 54. This movable support is'adapted to slide toward the right (Fig. 4) and is held in its normal position as in Fig. 4 by means of a spring 55 which is fastened at the front end thereofto the frame 5 and at the rear end thereof to a pin 56 which is fast to the movable support 54 and is adapted to slide in a slot 57 in th frame5. ThlS movable support performs the function of supporting the foremost toggle bar 14 in the raceway as it is being fed across the space or. opening 53. It also performs the tion of removing the end of the cord the cord carrier after from the toggle has been completed, as will be hereinafter more fully in a slot or guideway 58 formed in the frame 5 (see Fig. 14).

( 0rd manipulatingmechanism, (see Figs.

1, 3, 4, 5, 6, 14, 15,16, 17, 18 and diagrammatic views 22 to 29).-The toggle bar 14 now-being held in the position illustrated in Fig. 4, the next step is to pass the cord 59 beneath said toggle bar. The supply of cord 59 is contained in a spool 60 (Fig. 1) and passes from said spool through a tube 61 (Figs- 1 and 6) and over ,a slide 62 loosely mounted to slide longitudinally thereof inways 63 in the frame of the machine. The cord 59 is held at the front end of the slide 62 between two fingers 64 and ,65 both fast to the slide 62. I These fingers.

are now moved along In the bottom of the funcin and 65, together'with the slide 62, form a cord holder 62. (See Fig. 6 and the end view of said cord holder where it appears in Figs. ll, 15, 16, 17 and 18.) A stop pawl or finger 6'6 is pivoted at 67 to the slide 62 and is held in engagement with the cord 59 by a spring (58, thus preventing the cord from being drawn toward the left (Fig. (3) relatively to the slide 62, but permitting the withdrawal of the cord toward the right in said figure or toward the front of said cord holder.

The slide (32, together with the parts at tached thereto, is movable longitudinally of said slide and is also movable laterally thereof at its forward end. The longitudinal movement of the slide 62 is obtained by means of a cam (39 fast to the main driving shaft 2. This cam is provided with a cam groove 70 into which projects a cam roll 71 mounted upon a cam lever 72 pivoted at 73 to the frame of the machine. At the upper end of the lever 72 is a pin 71 swiveled in the arm 72 and this pin is connected by a pin 75 to a link 76 which, in turn, is connected by a pivotal joint 77 to another link 78 (Fig. 6 The link 78 is pivoted at its rear end by a. pin 7.9 to a block 80 which, in turn,'is rotatably mounted upon a stud 81 fast to the slide 62. Said link 78 slides in a swivel stud 78 (see Fig. (i said stud 78' being mounted to rock in the frame of the machine- A stop-screw 82 in the slide (32 is arranged to abut against the frame 5 when said slide 62 is in its forward position as in Fig. 6, this screw limiting the distance to which the slide can be moved forward by the mechanism hereinbefore described.

- In addition to the longitudinal movement of the cord holder, said cord holder has a lateral moement, and this -lateral movement is obtainedby means of a cam 83 (Figs. 1 and 3), said cam actuating a cam lever 8a pivoted at 85 to the frame of the machine and having pivotally connected thereto a slide 86 which has journaled thereon, at its forward end, a roll 87, this roll bearing against one side of the slide (52 (see Fig. 6). The slide 62 is held against the roll 87 by a spring follower '88 provided with a roll 89 which bears against the slide 62. Thus said slide'62 moves between the rolls 87 and 89 and is capable of longi tudinal movement and of lateral movement for the purpose hereinafter described.

-Assuming the parts to be in the relative positions illustrated in Fig. 6, it will be seen that the cord'59 is projectin for a considerrble distance beyond the front ends of the fingers 64 and 65 by which it is held, said fingers 64, 65 and the slide 62 forming, as a whole, the cord holder 62'; Said pro- .jecting end of the cord 59 is now to be carried transversely of the slide 62 beneath the bar 1 preparatory to passing said cord around the bottom. and two opposite sides of said bar by moving said bar downwardly against the cord as it is 'held therebeneath.

This operation of carrying the end of the g9 cord beneath the bar and holding the same,

preparatory to having the bar pushed down will now be described.

Referring to Figs. 1, 4;, 6, 14, 15, 16, 17 and 18, the cord 59 is taken from the end of the 75 cord holder 62 by a carrier 90 which is shown in detail in Fig. 20, in plan and in its position in the machine in Fig. 1. This cord carrier consists of a slide 91 arranged to slide in ways in the frame of the machine and to which alongitudinal movement is imparted by means of a lever 92 (Fig. 1) connected to said slide at 93. The cam lever 92 is pivoted at 94: to the frame of the machine and-has a rocking motion imparted 35 thereto by a cam 95 fast to the cam shaft 9. The slide 91 base hook 96 fast thereto and said slide 91 also hasa finger 97 loosely pivoted at 98 to the slide 91. A spring 99.

is fastened at one end to the hook 96 and at go the other end to the finger 97 and tends at all times to draw the finger 97 toward the hook 96. Assuming, now, that the cord is projecting from the end of the cord holle:

62, as in Fig. 6, the cord carrier 90 is moved 95 toward the right from the position illustrated in Fig. 14 to that illustrated in Fig. 15 and subsequently to that illustrated in Fig. 16. This is accomplished by the lever 92 which moves the slide 91 toward the right 100 (Figs. 1 and 14), thus moving the hook 96 and the finger 97 also toward the right with said slide. As the hook is moving toward the right, as hereinbefore set forth, it is raised just-before it reaches the projecting cord 59, as shown in Fig. 15, and the bent outer end of the hook is then droppe'dto the other side of the cord, as in Fig. 16. This lifting of the hook'is obtained by means of the slide finger 100 (Figs. 1, 4 and 5). The front end of this slide linger passes beneath a guide plate 101 adjacent the rear" side of the hook 96 and said slide finger X- tends at an angle upwardly through a guide.

102 and has on its rearward end a cam roll 103 adapted to be engaged by a cam projec tion 104 on the cam 105. A spring 106 is connected to the slide finger 100 and keeps the roll 103 in engagement with the cam 105.

Now, as the cord carrier moves forward to 129 engage the cord, as hereinbefore set forth, this slide finger 100 ismoved toward the left (Fig. 4) by the cam projection 104 and pushed beneath the hook, thus raising the hook 96 and also the slide 91 at its forward end slightly, in its ways, while the finger'97 remains stationary as to vertical movement and rests upon a cover plate 107. This lifting of the hook 96 is 0 early s an in Fi 15. When the hook is released by the sli e ee finger 100 moving backwardly, the hook drops down'to the position illustrated in Fig. 16 and the-free end of the cord 59 is prement toward the left (Fig. 17), the free end of the cord 59 is carried by the hook against a clamp-plate 108, said hook retreating into the slot 109 in said clamp plate and pinching the free end of thecord between itself and said clamp plate, (seeFig. 21.) The 'cord has now been carried from the-position illustrated in diagram, Fig. 22, by means of the cord carrier beneath. the. bar 14' and clamped against the clamp plate 108, substantially as illustrated in Fig. 24. Now, while the cord is held by the hook firmly at its free end,

the cord holder 62 moves toward, the right,

from the position illustrated in Fig. 14 to the position illustrated in Fig. 17 in full lines, thus paying out from the cord holder a certainamount of cord. The bar 14' is moved downwardly from the position illustrated in Figs. 4 and 14 to the positionillustrated 'in Fig. 17 and then to the position illustrated in Fig. 18. This downward movement of the bar 14 is performed by a slide 110 (Figs. 4, 14, 17 and 18). Referring to Fig. 4, it will be seen that the slide 110 is guided in ways in the frame of the machine and is actuated by a lever 111 pivoted at 112 to the frame of the-machine and having a rocking motion imparted thereto by a cam 1%3 which engages a roll 114 journaled on sai lever 111. The lever 111 has an arm 115 pivoted on a stud 116 fast to said lever 111. This arm engages at .its lower end a projection'117 on the movable support 54. Said arm 115'engages, on the side opposite to that upon which the projection 117 is located, a roll 118 journaled to rotate upon a pin 119 fast to the frame of the machine. The movable support 54 is pivotally mounted upon the pin 56, as well as slidably mounted upon the frame and is supported at its forward end by a spring 120, 'so that as the; lever 111 is. rocked the arm 115'w'ill be thrown toward the right (Fig. 4) during this downward motion by the'roll 118 which engagesan incline 121 upon said arm 115, thus forcing the arm 115 to the right and by its engagement with the projection 117 on the movable support 54 moving said' support 54 toward the right. The bar 14' is being, meanwhile, pushed down by the slide 110 and as it engages the support 54 during the first part of its downward motion, said support 54. will swing upon its and by the end plate 123, on the opposite side thereof, said plate 123 being fastened to and forming, in elfect, a portion of, a slide 124 which forms a partof the clenchlng mechanism and will be hereinafter more fully described. Said plates 122 and 123 form supports for the cord when the bar '14 is being moved downwardly between them. As the cord 59 is drawn downwardly by the bar 14 it will be seen that it will be'drawn over the upper edges of the plates 122 and 123, and at this time the cord holder 62 is moved at its forward end toward the left from the position illustrated in "full lines (Fig. 17) to that illustrated in dotted lines therein, and thus the cord is fed by said cord holder to the bar as the bar is beingjpushed downwardly, which prevents, to a large extent, any unnecessary strainer fraying of the cord which would be caused by pulling the same around the corners of. the bar 14 and at the same time ullin the cord out of the cord holder. Thls cor holder,,therefore, acts as a. feeding element at this pararound' the three sides of the bar. The bar having now arrived at the position illustrated in Fig. 18, with the cord held around the bottom and two opposite sides thereof,

the next step 'is to drive; the staple through the bar until the closed end of the staple engages the cord at one side of the bar and a subsequently to bend the legs of the staple, where they project beyond [the bar, toward each other and thenclench them against the cord on that side of thei'bar, thus firmly uniting the cord and the bar by means of the staple on opposite sides of said bar. Iwill, therefore, now proceed to describe the wire feeding and staple forming mechanism.

Wire feeding dad staple'formz'ng me0ham'sm, (Figs. 1, 9, 14, 18 and 19 .)'The wire. 125 is wound on a reel 126 (Fig. 1) and is 'ticular part of the operation, to feed the cord to the bar while the same is being wrapped fed toward the frontof the machine by the feeding mechanism illustrated in Fig.- 9,

in which the wire asses through guides 127, 128, 129 and 130 etween the feed roll 131 and the'idler roll 132 which is held against the wire with a'yielding by the spring 133. The feed rol 131- is mounted upon a stud 134 and has a ratchet 135 fast thereto which is operated by a pawl Y 136 pivoted to a lever 137 which is pivoted at 138 to the frame of the machine and is rocked by a cam 139. The wire is thus fed forward between two cutters, via, the stationary cutter 130,. which also acts as a wire guide, and the Vertical movable out v 12.0 ressure purpose of landing the ter 140 which is adjustably fastened to a slide 141 adapted to slide in suitable ways in the frame of the machine and operated by a lever 142 pivoted at 143 to the frame of the machine, said lever being rocked by the cam 139'. See Figs. 1 and 8. The wire is fed bet-ween the cutters 140 and 130 by the feeding mechanism hereinbetore described and is fed against a stationary stop 144. It is then cutofl by the cutters 140 and 130 coacting together and the piece thus cut off, which is to be bent to form a staple, drops upon a forniing die 145, (Figs. 14 and 18.) Then this piece of wire 125 which has been cut from the main portion of the .wi're 125, as hereinbefore ,described, is pushed forward on said forming dieby a slide 146 until'it falls into a groove 147 in the upper surface of said forming die. 6 The slide 146 is given a reciprocatory motion for the piece of wire 125' in the groove 147 by a lever 148 (Fig. 1) which-is pivoted at 149 to the frame'ot the machine and is rocked by acam 150. The lever 148 is connected by a link 151 to the slide 146. The Wire 125 is bent to form a staple by the male formerh152 which is grooved on its opposite sides 153, 153 and receives a vertical rtaciprocatory motion said slide being guided in suitable ways in The staple from a slide .154 to which it is fastened,

the frame of the machine and moved by a lever 155 pivoted-at 156 to the frame ot the machine (Fig. 1) and rocked by a cam 157. The wire is forced down through. the female former or die 145 by the male former 152 and is bent to form a U-shaped staple 125 in the grooves 147 which extend vertically down through the female former 145 (see Figs. 14 and 19). After the male former has ushed; the wire down and formed the stap e in the female former 145, it still further pushesit out of said female former and into grooves 158, 158 in a segmental carrier 159, (Fig. 19.)

Assuming this segmental carrier at this time to be standing in the position illus trated in Fig. 18, it is rocked througlran angle of about ninety degrees into the position illustrated in Fig. 14 by a rack 160 which meshes into a gear 161 fast to said segmental carrier. The rack 160 is guided in Ways formed in a bracket 162 (Fig. 1) andv has a reciprocatory motion imparted thereto by a lever 163 pivoted at 164 to the frame of, the machine and having a rocking motion imp .rted thereto by the cam 165.

This slide has 611 its upper surface a. holder 167 which is grooved on op osite sides at 168 to receive the. staple, and t e staple is pushed into said grooves 'tuated by a cam 175'. It

are pivoted upon pins as in Fig. 18,

168, 168 by a slide 169, said slide 169 constituting a driver which drives the staple into thebar .14. A reciprocatory motion is imparted. to the slide 169 to push the staple into the grooves 168, 168by a lever (Fig. 1) pivoted at 171 to thetrame of the machine and, rocked by a cam 172. The slide 166 has a reciprocatory motion imparted thereto by a lever 178 pivoted at 174 to the frame" of the machine andacwill be understood that when the bar 14 the position illustrated'in Fig; 18, the slide 166 is then brought forward to clamp the bar against the end plate .123 of the slide 124, and on the top of this slide,'at the front end thereof, is a cord guide 166 which moves up with said slide 166, with its front face against the bar 14 and adjacent to the plate 122. The slide 166 now having clamped the. plate 123, the slide 169 advances and drives the staple out of the grooves 168,

168 and throughthebar, with its closed end engaging the cord on one side of the bar and the free ends of the legs of the staple projecting through the bar on the opposite side thereof, as illustrated in Fig. 11. The next step is to clench the legs of the staple over the cord and against the bar 14 and this is done by the clenching mechanism illustrated in Figs. 1, 5, 10, 11, 12, 13 and 14.-

The slide 124 has mounted therein two other slides 124' and 126. The ends of the legs of the staple are first pinched toward each otherby apair of levers 176 and 177 which tively, said pins- 178 and 17 9 being fastened to the cover 107 of the slide 124 and at their lower ends extending into said slide 124.

The driver slide 126is then advanced to the position illustrated in Fig. 13 from .that illustrated in Fig. 12 and the ends of the legs of the-staple are firmly clenched and driven against the bar and against the cord 59, on that side of the bar. During this driving and clenching ofthe staple, the

slide 110 movesupwardly from the position.

illustrated in Fig. 18 to that illustrated in Fig. 4, and in so moving allows. the support 54 to resume the position illustrated in Figs. 4 and 4". The pin 56' projects from the j front end of the .movable' support 54', the

function of this pin being to free the hook '96 of the cord when the completed toggle is'being taken out of the machine; v

6 and 18.) -While the staple is being driven the cord is measured as inthe form of a loop and subsequently one side of said loop, viz., the side extending to the cord spool, is

cut 'ofi'. This measuring of the loopis for the long end ofthe toggle strin and is accomplished bymeans of a. cor measuring device consistin of a slide 199' '(Fig. 1)- which has a rac 200 thereon. This rack is guidedin suitable ways in the frameof the machine and has a reciprocat'ory motion imparte'd thereto by a ear 201 (Fig. 3) which is rotatably mounte upona stud 202 fast to the frame of the machine and projecting downwardly underneath said frame. The gear 201 has a pinion 203. fast thereto which -meshes into a rack 204 adapted to slide in suitable ways in the frame of the machine and connected by a link 205- to the upper end of a cam lever 206. The cam lever 206 is pivoted to the stationary shaft 73 and has a rocking motion imparted thereto by cam 208'. The slide 199 has an arm 209 and the y this arm has rotatably mountedthereon a spool 210 (Figs. 6 and 18). Said spool has. a flange 211 at its lower end and another flange212 at its upper'end and is free to slide in the end of the arm 209, but is kept normally in the position illustrated in Fig. 6 by a spring 213 which bears against the upper end of saidspool. 1As the slide 199 is moved in the direction of thearrow a (Fig. 1) the flange 212 on the upper end of the spool 210 engages an inclined flange 214 onan arm 21-5 pivoted at 216 to the frame of the machine and heldin the position illus trated in Fig. 6 by'a flat spring 217 against a pin 215. The flange 212 ofthe spool 210 rides up on the flange 21 1 and moves the spool longitudinally thereof in the arm 209.,

lifting the spool and the flange 211 onthe bottom thereof over the cord 59, and. when the spool has been moved to a suificient'extent' in the direction of the arrow at (Fig. 1) the flange 212 drops ofi' of the flange 214 behind said cord, asillustrated in Fig. 18, and said flange 212 engages the flange 214: upon its underside, .the arm 215 tipping toward the right (Fig. 6) upon its pivot 216 to allow the spool in its motion toward the front of the machine to pass by the arm 215 without being raised longitudinally thereofl Then, upon .,a reversal of the motion of the slide 199, the spool 210 draws the cord 59. forward in the form ofa loop,-one end of the cord.

. being 'fastened to the baril, which is held firmly grippedat this time between the slide 166 and the plate 123 on the slide 124, the other end of the cord bein drawnout from the cord holder 62 and o of the spool 60. As the spool 210 moves to draw out thisloop of cord, the cord-passes from the bar around the guide 166, as illustrated in Figs. 11 and 12, and thus the cord is revented from being cut on the staple. ile the cord is thus being measured, the cord holder 62. moves rearwa'rdly or toward the left (Fig. 6) and when the slide. 199 has moved to the distance necessary to measure oil the loop, as hereinbefore described, the spool 210 engages the clamp 211 (Fig.- 1). The cord w ich extends around the-lower part'of said spool is clamped between this clamp required. length of cord in the form of a 211' and the spool. The'clamp 211 slides on a support 212 and is held in yielding engagement with the cord by means of a spring 213'. The cord is now firmly held at one end by the bar 1.4 to.which it is secured.

'At the other end it is held in the cord holder 62' andintermediate thesetwo ends, in the form of a loop, it is held between the clamp 211' and the s 001 210. The length of cordwhich forms the tog 1e is now cut from the main part of the cor in the machine by the following described mechanism.

00rd mttz'ng mechanism, (Figs. 1, 3, 6, and 14.) -This cord cutting mechanism consists of a lower cutter 218, an upper cutter 219, a lower clamp 220 and an upper. clamp 22L (see Fig. 6). The lower cutter 218 and the clamp 220 are moved upwardly by a slide 222 which is guided in suitable ways in the frame of the machine and has a vertical reciprocatory motion imparted thereto by a lever 223 pivoted at 224 to the frame of the machine and actuated by a cam slide 225, one 'end of which is pivotally connected at 226 to said lever 223, the other end of which is bifurcated so as to slide upon the shaft 2. A reciprocatory motion is imparted to the cam slide 225 by a cam 227. A vertical reciprocatory motion is imparted to the upper cutter 219 and clamp 221 by a slide 228 to which the cutter 219 is adjustably fastened andupon which the clamp 221' is yieldingly mounted-that is, said clamp 221 is adapted to slide in the slide 228 ,against the action of a spring 229. The slide 228 is mounted in suitable ways in the frame of the machine and is fastened to a rod 2.30 which extends downwardly through the frame of the ma- 25 chine and is fastened at its lower end to another slide 231 adapted to slide in suitable ways in the frame of the machine and actuated-by a. link 232 which is pivotally connected to a lever 233. The lever 233 is pivoted at 234 to the frame ofthe machine and has pivotally connected thereto, at its rearward end, a cam slide 235 which is bifurcated to straddle the shaft 2 and which has a. reciprocatory motion imparted thereto by the cam 236. The operation of this cutting mechanism is as follows: The cord holder having withdrawn from bet-ween the cutters 218 and 219, said cutters, with theclamp plates 220' and 221, are advanced toward each othei the clamp plates 220 and 221 engaging the cord 59 and holding it firmly clamped between them. At this time the slide 222 stops its upward movement andthe cutter 218 and clamp plate 220 remain stationary. The upper slide 228 continues its downward movement, but the clamp 221 remains stationary, the spring 229 yielding to allow it so to do, while the cutter 219 continues its downward movement, and coacting with the lower cutter 218, cuts the --cord necessary to form the toggle cord from the main portion of the cord 59.

Toggleejecting. mechanism, (Figs. '1, 3 and27.)-As soon as the cord 59 has been cut, as hereinbefore described, thatside of the loop of the cord which is measured out, as hereinbefore described, and which is adjacent to the cord cutters, is knocked down out of the way by an ejector. This cord ejecting mechanism consists of a rotary ejector 237 which has two arms 238 and 239 fast theret0,the arm 238 being shorter than the-arm 239. The ejector 237 is fastened to a shaft 240 which extends rearwardly from.

raceway 247 (F gbars are fed along the raceway resting upon the the front of the machine and has a rotary motion imparted thereto by a sprocket 241 fast to said shaft and driven by a chain 242 (Fig. 8) which, in turn, is driven by a sprocket 243 fast to the shaft 13. As soon as the arm 238 (Fig. 27) of the rotary ejector has knocked the side 244 of the loop 245 downwardly out of the way, subsequent to the cutting operation hereinbefore described, the other arm 239 of said rotary ejector moving downwardly and being longer than the arm 238 engages the side 246 of said loop 245 and at this time the bar is free from the slide 166. The vertical slide 110 is moved up out of the way so that when the arm 239' strikes the side 246 of the loop it will knock that side of the loop downwardly, together with the bar 14' and the cord which surrounds it, it being understood that at this time the hook 96 has moved forward, releasing the other end of the cord from the clamp plate 108, and that other end of the cord has the pin 56 on the end-of the movable support 54, so that the toggle bar and the end of the cord attached thereto being free, said toggle bar is thrown downwardly by the arm 239 and subsequently the slide 199 moves forward releasing the other endof the cord from the clamp 211 and the toggle bar and. it's attached cord, completed, fall into the said toggles descending said raceway, which may be of any suitable form, and hanging, with the bars of the toggles on the upper side of the raceway and the cord hanging downwardly through a space 248 between the two side plates 249 and 250 forming said raceway. F roin this position they may be easily removed from the machine.

To prevent the end of the cord 59 from being thrown laterally toward the rightout been pushed out. of the hook by of the path of the hook 96, and also to assist in properly guiding the end of the cord after it has been cut and the same thrown downwardly by the toggle ejector, a wire stop or guard 251 is providedtFigs. 3, 6, 14 and 18).

The general operation of the mechanism hereinbefore specifically and to some extent, in general described. is as follows: Referring to Figs. 22 to 29 inclusive, the toggle 24 by. the series of rotary feed fingers 44, as hereinbefore described, until the row of 'toggle, bars; end to end, fills the raceway, as illustrat'ed in Fig. 4, the toggle bar 14 atthe front of the machine being held, as hereinbefore described, against the stop' 52 and movable slide support 54. At this time a certain amount of. cord projects beyond the end of the cord holder 62, as seen in Figs. 6 and 22. The hook 96 is now carried forward beneath the bar 14 and is lifted to pass over the cord, as-seen in Fig. 15, this lifting of the hook beingintense performed: by the slide finger l'00 '(see Figs. 4-and 5). The hook drops over the projecting portion of the cord 59 (see Fig. 3) when the slide finger 100 retreats. The cord" is then held in the hook 96 and over the finger and finger 97 now retreat andcarry the cord 59 beneath the bar 14- (see Fig. 24), the

and from the bar 14, paying out a certain amount of the cord 59, leaving the parts in the position ilhistratedin-Fig. '24, the cord holder'62 being in the position shown in full lines (Fig. 17). The bar 14 passes between the plates 122 and. 123 (Fig. -17), carrying the cord down with it and wrapping said cord around the bottom and two opposite sides of said her 14. 'The bar is pushed farther down from the position illustrated in Fig. 17 to that illustrated in l8, and during this downward movement of the bar, the cord holder moves from the position illustrated in full lines (Fig. 17) to .thatillustrated in dotted lines therein, thus paying out cord to the bar as it is being pushed down between the plates 122 and 123.

and preventing the rending of the cord around the edges of the bar 14 The cord holder then moves back to the position illustrated in Fig. 18, drawing some cord from the cord holder and placing it in position for the ineasurerto come forward and measure oil the loop of cord. When the parts are in the position illustrated in Fig; 18,

- the'staple which has been formed as hereinbefore described and positioned by the 4G segmental carrier in the position shown in Fig. 14 is driven through the bar 14, said bar being held clamped at this time between the slide 166 and the front plate123 of the slide 124. The staple having been driventhrough the bar, as shown in Fig. 11,'the' 1 fingers 176 and-177 are moved toward each other at their front ends by the movement of the slide124 and the ends of the legs of the staples are bent, as illustrated in Fig. 12, whereupon the slide 126 advances and engages said ends of the staple and holds them and then-the slide 124 retreats, causing the fingers 17(3 and 177 to spread apartand the driver slide 126 is then advanced, driving and clenching the projecting ends of l the cordand against the bar 14.,

During this operation the vertical slide '110 has the removal of the completed toggle from 97, as illustrated in Fig. 16'. The hook 96 the legs of the staple againstthe machine. During the movement hereinbetcre described; the penis "drawn out, as illustrated in Fig; 27, by the measuring spool 210 by reason of the slide 199 moving. toward the front of the machine in a'direeibti'o'n opposite to the arrow dz and the cord is gripped by the said measuring spool against the clamp 211. Now the cord cutters 218 and 219 and the clamps 220 and 221. 'approach each other, the cord holder 62 hav- 1% ing retreated from between said cutters and clamps to a position considerably in the rear. thereof, so that when the cutters a proach each other and the cord is clamped between the clamps 220 and 221, said cord will be g out oil by said cutters at a considerable dis= tance in advance 'of the extreme end of the cord holde'r or of the spring fingers 64 and 65 of said cord holderand will, therefore, after having been out ofi, project beyond the 5% ends of said fingers, as illustrated in Fig. 6, preparatory to another fo'rward Iiiovenient of the hook to secure the same and draw the cord out for-another toggl. Almost simultaneously with the cutting off of the $6 cord, the short arm 238 of the ejector 237 strikes the side 244 of the loop- 245 (see Fig. 27) and knocks this side-of the loop downwardly out of the way of the media: nism, and this; is followed by the arm 2'39 Q5 striking theside 246 of the loop 245;, which occurs just after the bahlia's been released Y from between the slide 166 and the frontplate 123; Thehook 96 also having moved slightly forward hasrel'eased the other end rub of the cord from between itself and'the clampplate 108, so that the tb'ggle bar and Y its cord are free to be thrown downwardly out of the machine, which is done by the arm 239 striking the side 246 of the loop 245, as hereinbefo're set forth, and almo's't simultaneously with the striking of this'side 246 by the am 239, the cord is entirely re leased from the machine bythe measuring spool 210 being moved forward to release tie the cord from between itself and the 'clarhp 211', The completed toggle then falls into the raceway 247 and down said raceway tb the position illustrated in Fig. 3.-
