Applieationnlcd February 19, 1924. Serial Io. 693,909.
My present invention relates to lace tipping machines, and more particularly to an improved lace tipping machine for applying-tips of mouldable material or sheet material of either metal or non-metal substances.
Applying a tip to the ends of lacings has been, heretofore, essentially a hand operation in that it was necessary to manually position the endof a lacing in position in a forming die. After the positioning operation, the operator pressed atreadle to cause the die to close on the end of the lacing and roll or form the tip on the lacing. Because of the relatively low price at which lacings are sold, the margin between manufacturing cost and selling cost was too low to allow a reasonable profit to the manufacturer, and attempts have been repeatedly made to perform the tipping operation automatically and by machine. The ideal machine for this purpose is one that will take a lacing of indefinite length, feed the same continuously,
' divide and separate such lacing into a phrality of lacings of predetermined length, move the said plurality of lacings into position relative to a predetermined amount or length of tipping material, apply thetip to the ends of the lace, and bunch such tipped laces into bundles of predetermined size or number.
My present invention is capable of carrying out this ideal set of operations or process and in practicing my invention, I do not limit myself to the use of sheet material-' either metal or non-metalas my invention is broad enough to include the use of mouldable materiah The principal object of my invention therefore, is to provide a machine which will automatically apply tipping material to both ends of the lace in a uniform and equal manner and with equal lengths or amounts of tipping material; automatically space the ends of the lace; automatically feed, hold under tension and continue the feeding of the tipped lace out of the machine.
Another object of my invention is to pro vide a novel mechanism for feeding the lacing and depositing the same upon the work support Where it is clamped at the opposlte forming the tips, the lacing bem ends of said work support and thereby held in position to have tips of celluloid, brous or other suitable material simultaneously applied thereto by the tip forming instrumentalities, provision being made for automatically preventing the tipping material from being fed to the machine if the lacing is not in osition to receive the tip.
A furt er object of my invention is to so construct the tip forming" instrumentalities that corrugations may be formed upon said tips simultaneously with the operation of severed between the adjacent tips while sai tips are being formed.
A still further object of my invention is to provide means for automatically stopping the machine in the event of a snarl apearing in the lacing.
A further object of the invention is to provide means for varying the length of the aces.

5-5 of Fig. 3, as viewed from the left suitable clutch member 5.secured thereto and therefore rotatable therewith. Another clutch member is keyed to the shaft 3 and is thrown into and out of engagement With the clutch member 5 by means of a shifting lever 7 which is pivoted at 8 to the frame 1. Fast to the shaft 3 is an eccentric 9 which is adapted to impart a reciprocatory motion to a horizontal slide 10 to which it is operatively connected by an eccentric strap 11, rod 12 and member 13, the said member 13 being secured to the slide 10 by a pin 14. The slide 10 is arranged to slide in suitable ways 15 provided in the frame 1 and the position of said slide may be adjusted for purposes hereinafter appearing by means of the rod 12, which is provided with right and left hand screw-threaded portions having engagement with the member 13 and the eccentric strap 11 respectively. The rod 12 when properly adjusted is locked to the member 13 and strap 11 by lock nuts 16 and j 17 respectively.
A pair of strips of sheet material 18 from which the tips are formed are placed side by side With a short distance intervening between their adjacent edges and fed vertically into a position to be engaged by the tip forming instrumentalities by mechanism which is as follows :-Fast to the lug 19 projecting downwardly from the slide 10 is a cam 20 which is adjustably secured to said lug by the bolt 21 which passes through a slot 22 provided in the cam. The Working cam surface is composed of an inclined edge 23 and a horizontally disposed edge 24, the said edge 24 constituting a rest. A cam roll 25 is rotatably mounted upon a cam arm 26, one end of which is pivotally attached to a stud 27 projecting from the frame 1. A
spring 28 acts to always hold the cam roll 25 against the working surface of the cam 20. The outer end of the cam arm 26 is provided with a slot 29 through which extends a stud 30 which is adjustably mounted in a slot 31 provided in an arm 32 pivoted upon a shaft 33 adapted to rotate in the frame 1. A pawl 34 carried by the arm 32 is forced by a spring 35 into engagement with a ratchet 36 fastto the shaft 33 and the rocking movement imparted to the arm 32 by thearm 26 and cam 20 feeds the ratchet 36 a predetermined number of teeth with each forward movement of the reciprocatory slide l0. The number of teeth engaged by the pawl 34 with each rocking movement of the arm 32 may be varied by adjusting the location of the stud 30 upon the arm 32. N
Fast to the shaft 33 and rotatable therewith is a feed roll 37 to which is fastened a spur gear 38 which meshes with and drives another spur gear 39 fast to another feed roll 40. The feed roll 40 is rotatably mount-v ed upon a shaft 41 supported in a pair of arms 42 forming a part of a lever 43 which is pivoted to rock updn a shaft 44 supported in the frame 1. I a
An arm 45 forming a part of the lever 43 is located upon the opposite side of the shaft 44 from the arms 42 and said arm 45 is rovided with an adjusting screw 46 W ich extends therethrou h having a shoulder formed thereon and between said shoulder and a portion of the frame 1 is located a spring 47 which acts to force the feed roll 40 against each strip of sheet material 18, thereby causing each of said strips to be fed simultaneously at such times as the feed rolls are rotated. After leaving the feed rolls the strips of sheet metal 18 pass through guides 48 which correctly position each strip prior to its presentation to the tip forming instrumentalities where a piece of material is severed from each strip and deposited upon a work support 49, as will be hereinafter more fully described.
Material A, which is furnished in a continuous length, is fed longitudinally and deposited upon the Work support 49 in a position to receive the metal tips by mechanism as follows:-Fast to the shaft 3 is a spiral gear 50 which meshes with and drives another spiral gear 51 fast to a shaft 52 mounted to rotate in bearings 53 and 54 provided upon the frame 1. A crank 55 is attached to the shaft 52 being adapted to impart a reciprocatory motion by means of a connecting rod 56 attached thereto to a slide 57 mounted in ways 58 provided in the frame 1. The slide 57 has rack teeth 59 formed thereon. A bracket 60 is adjustably of a hollow tube is adjustably mounted.
upon the oscillatory member 63 being attached thereby by a clamp 68 and fast to the outer end of said arm is a pair of grippers consisting of a stationary gripping member 69 provided with a jaw 70, Fig. 15, and a movable gripping member 71 which Is slidably mounted upon the member 69 and which is provided with a jaw72. The griping member 69 has a projection 73 extendmg downwardly therefrom having a bevelled edge 74 adapted to deflect the lacing A and allow the gripping member to pass beneath said lacing and assume a position as' illustrated in Figs. 1 and 3 in which position the -lacing may be "ripped between the jaws 70 and 72 at the pi oper time.
The mechanism which operates the movable gripping member 71 andcauses said member to automatically grip the lacing A between the jaws 70 and-72 and finally releases said lacing therefrom is as follows Mounted adjacent to the arm 67 and parallel thereto is a rod 75, one end of which projects through the oscillatory member 63 by which it is supported. At a suitable point, intermediate its length, the rod 75 is supported in a bearing 76 which in turn is supported upon the arm 67. Collars 77 are fast to the rod 75 upon opposite sides of the bearing 76 and contacting therewith, thereby preventing a longitudinal movement of said rod in said bearing. The other end of the rod 75 has a sleeve 78 fastened thereto-which projects through the stationary gripping-member 69 being supported thereby. A pin 79 is eccentrically mounted in the end of the sleeve 78 and projects through a slot 80 provided in the movable gripping member 71, see Fig. 15. The sleeve 78 and pin 79 therein constitute a crank by which a reciprocatory motion is imparted to the movable gripping member 71 in order that the jaws 70 and 72 may be opened and closed. The rod 75 is rocked by a member 81 which is clamped to said rod, the said member beingprovided with a projection 82 which is adapted to contact with cam surfaces 83 and 84 provided upon the bracket 60 as the member 63, arm 67 and rod 7 5'oscillate in unison to feed the lacing.
In the, position illustrated in Figs. 1 and 3 the projection 82'is in contact with the surface 83. thereby causing the lacing A to be gripped. between the jaws 70 and 72 and the lacing will remain gripped between said jaws during the feeding operation until the projection 82 contacts with the cam surface 84 when the lacing will be released.
During the feeding operation it is desirable that there be a tension upon the lacing which .is inserted between the frame 1 and an arm 94 forming a part of the lever 91.
A thumb screw '95 located in the lower end of thearm 94 provides a means for adjusting the pressure upon the lacing A as It passes between the rolls and 86.
Mcans are provided for automatically stopping the machine in the'event of a snarl in thelacing A, the mechanism for accom-- plishing this result being as follows: An arm 96 provided with an eye 97 is attached to a pin 98 which constitutes a pivot therefor, the said pin being mounted in a lug 99 formed integral with the frame 1. Also fast to the pin 98 is another arm 100 which overlies one end of a latch 101 pivoted at 102 to the frame 1. The latch 101 is notched at 103 and engages the shifting lever 7 which rests within said notch when the machine is running as illustrated in Figures 1 and 3, thereby holding the clutch member 7 in locking engagement with the clutch member 5. Spring 104 acts to pull the notched end of the latch 101 into ,engagement with the shifting lever 7, While a spring 105 is suitably located to throw the forward end of the shifting lever toward the left in Figure 1 at such times as said shifting lever is released by said latch.
If a snarl appears in the lacin A, said snarl upon arriving at the eye 97,, eing unable to feed therethrough, will cause the arms 96 and 100 to rock in unison, thereby rocking the latch 1 01 whereupon the shifting lever 7 will be released and the machine automatically stopped. The latch 101 may also be rocked to manually release the shifting lever 7 by a rod 106 which is connected to a suitable foot treadle not shown.
After the lacing A has been fed and is resting upon the work support 49, it is necessary that said'lacing be clamped at the opposite ends of. said work support during the interval that the tipsare being formed therearound. The mechanism for so clamping the lacing is' as follows :Referring to Figs. 1 and 14:. located adjacent to the opposite ends of the work support 49 and extending port 49. Located in the forward portion of each bore 108 with its rear end projecting into the groove 110 is a clamping member 111 which is normally held in the position illustrated. in Figs. 1 and lfl by a spring 112 also located in the bore 108 under compression between said clamping member 111 and a screw 113. A stop pin 114 projecting from the clampin member 111 into a. slot 115 provided in t to cylinder 109 limits the hole. 119. A spring 123. under compression surrounds the stem 118 between the end of the connecting rod 120 and the shoulder 117 of the clamping member 116 and acts to normally hold the stop pin 121 at the forward end of the slot 122 as illustrated in Figures 1 and 14. A reciprocatory motion is imparted to each clamping member 116through the connecting rods 120 by the horizontal slide 10, a bar 124 extending transversely through said slide and projecting through slots 125 in the frame 1, the connecting rods 120 being attached at the opposite ends of said bar. As the horizontal slide 10' moves forward, the clamping member 116 will also move forward until the lacing A is clamped between the adjacent ends of the clamping members 111 and 116, after which the horizontal slide 10 will continue to move forward and the connecting rod 120 will move forward upon the stem 118 thereby compressing the spring 123'between the shoulder 117 and the end of the connecting rod 120.
The instrumentalities for severin a piece of'material from each strip 18, rolling each of said'pieces around the lacing A, severing the lacing between the pieces of material while the same is being rolled around the lacing, pulling the severed ends of the lacing a short distance apart so that said ends will be located inside the finished tip and for finally crimping the sheet material around the severed ends of the lacing are as follows :--Fastened t the slide is a member 126 which is provided with a cutting edge 127 adapted to cooperate with a cutting edge 128 provided upon the work support 49. The member 126 is furthermore provided .with a tip forming recess 129 having a curved rear wall which intersects the cutting edge 127 and is provided with a pluralit of grooves 130 formed therein, see
"Fig. 12. The member 126 constitutes a movable tip forming member. A stationary tip forming member 131 abuts against the work support 49 and is provided with a curved tip forming recess 132 having grooves 133 formed therein. The work support 49 and stationary tip forming member 131 each rest upon a horizontal portion of the frame 1 and The cutting edge of the cutter 135 is prefer-.
ably located a short distance in frontof the curved rear wall of the tip forming recess 129. The cutter 135 co-operates with a stationary cutting edge 137 provided upon the tip forming member 131. Projecting downwardly from the under surface of the tip forming recess 129 adjacent to the opposite sides of the member 126 are pins 138, while formed in the upper surface of the tip forming member 131 are rooves 139 into which the pins 138'may pro ect during the forward movement of the member 126. As the slide 10 moves forward, the front edge of the member 126 contacts with the upper end of each of the strips of sheet material 18 as illustrated in Fig. 7 bending said material and folding it so as to rest upon the lacing A as illustrated in Fig. 8. The cutting edges 127 and 128 then co-operate tosever a piece of material 140 from each strip 18 and then push the lacing with a piece of material restin thereon forwardly as illustrated in 9. As the forward edge of each piece of material 140 reaches the curved recess 132 in the tip forming member 131, said forward edge commences to bend around the lacing A but before the completion of this operation the cutter'135 co-operates with the stationary cutting edge 137 to sever the lacing between the two pieces of material 140. Subsequent to the severing of the lacing A but still prior to the completion of the operation of bending the pieces of material 140 around the lacing, the pins 138 engage the lacing A. and push the same a short distance into the grooves 139. This pulls the severed ends of the lacing outwardly a short distance and at the completion of the operation of rolling the pieces 140 around the lacing, the material comprising the tip will project a short distance beyond the end of the lacing, and because of the lack of material at the verv end of the finished tip the tendency will be to form-a more pointed tip thanwould be the case if the lacing reached to the end of the tip. At the extreme forward movement of the member 126 the grooves 130 and ridges therebetween will cooperate with the grooves 133 and ridges of the tip forming member 131 and crimp the pieces ofmaterial 140 around the lacing A so that for its entire length each completed tip has ridges extending completely therearound.
A hole 141 is provided in the tip forming member 131 in alignment with the cutter 135 and the short piece of lacing cut from the length of lacing when the same is severed is pushed by the cutter 135 into said hole and drops downwardly therethrough.
movement to the shaft 150 and member151 I fast thereto. As each raised portion 152 of the member 151 engages the projection 153 of the arm 146, said arm will be rocked thereby pulling the feed roll 40 out of em 70 gagenient with the strips of sheet material 18 and permitting the pin 145 to fall "be-,1
material 140 severed from each of the strips 18 thereby preventing waste of said material and also preventing an unused plece of said material from clogging the tip forming instrumentahties. Means are, therefore, provided for preventing the strips of sheet material from being fed if the lacing A is not properly clamped between the jaws 7 0 and 72 of the grippers 69 and 71 and deposited in position upon the work support 49 to receive the tipping material. Pivotally mounted upon the frame 1 at 142 in a position to be engaged by the lacing A just prior to being deposited upon the work support 49 is a lever 143, the normal position of which is illustrated in full lines in Fig. 2. A fiat spring 144 engages the underside of the lever 143 and acts to always force said lever upwardhave been applied to the lacing A and the lacing severed therebetween, the right hand lacing illustrated in Figure 1 is completed 90 ly. The lever 143 is operatively connected with a vertical pin 145 which, in its lowered position, projects in the path of an arm 146 which is pivoted at 147 to the frame 1. A link 148 connects the arm 146 with the shaft 41 upon which the feed roll 40 is mounted. Rotatably mounted in suitable bearings 149 provided in the frame 1 is a shaft 150 and fast to said shaft 150 in vertical alignment with the arm146 is a member 151 which is provided with a plurality of raised portions 152 formed upon the periphery thereof which are adapted to contact with a projection 153 formed upon the arm 146 and inter mittently rock said arm asufiicient distance to allow the pin 145 to drop in the path of the upper end of the arm 146. An intermittent motion is imparted to the shaft 150 by mechanism as follows :Fast to the lug 19 upon the opposite side thereof from the cam 20 is a cam 154 which is provided with an inclined edge 155 and a horizontally disposed edge 156, the latter constituting a rest.
7 A lever 157 constituting in effect a bell crank lever is pivotally mounted upon the stud 27 and is provided with an arm 158 at the outer end of which is mounted a cam roll 159. A spring 160 acts to always hold the cam roll 15 9 in engagement with the working edge of the cam. Another arm 161 of the lever 157 is connected through the medium of a link 162 with an arm' 163 of a bell crank lever 164 mounted to rock upon the shaft 150. An arm 165 of the bell crank lever 164 has a pawl 166 pivoted thereto at 167. The pawl 166 engages a ratchet 168, being held in-engagement with said ratchet by a spring 169. The number of teeth upon the ratchet 168 corresponds to the number of raised portions 152 upon the member 151. lVith each movement of the slide 10 the lever 157 will be rocked thereby rocking the bell crank lever 164 and imparting an intermittent rotary hind the upper end of the arm 146 thereby relieving the pressure upon the material 18.
As long as there is no lacing .A present between the jaws 70 and 72 of the lacing feeding instrumentalities the strip of material 18 will fail to feed, but when said lacing is properly clamped in position as said lacing is deposited upon the work support 49, said lacing will engage the lever 143 forcing the long aru'rthereof downwardly thereby raising the pin 145 from behind thearm 146 and again allowing the spring 47 to force the feed r611 40 against the strip of material 18 there- 35 by allowing said material to feed.
After the two pieces of sheet material 140 and that portion of the lacing which rests upon the work support is removed from said work support by means of an arm 170 formed integral with the crank 55 which, as said crank is rotated, engages the lacing A and lifting the end portion thereof from the work support drops said end over the edge of the frame 1.
The general operation of the machine briefly described is as follows :--The lacing A extending through the eye 97 of the arm 96 and passing between the rolls 85 and 86 extends to a point adjacent to the end of the work support 49 where the end portion thereof is held between the clamping mem- 1 bers 111 and 116. As the arm 67 1s oscillated'through the medium of the reciprocatory slide 57 to the position illustrated in Figures 1 and 3 the lacing A will be automaticallygripped by the jaws 70 and 72 of the gripping members 69 and 71 carried by said arm 67. The arm 67 is then oscillated through an arc of approximately 180 degrees pulling the lacing A between the rolls 85 and 86 against the tension thereonprovided by the spring 93. As the arm 67 reaches the latter part of its movement toward the right the lacing A is deposited upon the work support 49 and-when resting thereon extends through the grooves 110 of the clamping devices 107 located adjacent to .the opposite ends of the work support and the lacing A is immediately clamped in position by means of the clam ing members is deposited engagement with the strip of sheet material 18. When the lacing A engages the lever 143 the long arm thereof is forced downwardly thereby lifting the pin 1 15 and re leasing the arm 1&6 whereupon the feed roll 40 will be forced against the strips of sheet material 18 by the spring 47. The lacing A i deposited by the lacing feeding instrumentalities upon the work support 19 toward the end of the rearward movement of the slide 10 and immediately thereafter with the first portion of the next forward movement of said slide 1'0 the strips of sheet material 18 are fed upwardly by the said rolls 37 and 40 the required distance. If, for any reason, the lacing is not properly fed by the feeding instrumentalities and not deposited upon the work support, the lever 143 will not be moved and the feed roll 40 being out of contactwith the strips of sheet material 18 will fail to feed said material. This will prevent any clogging of the tip forming instrumentalities by preventing a tip from being formed if there is no lacing present to receive said tip. If, during the feeding operation, a snarl appears in the lacing A as said snarl reaches the eye 97 of the arm 96 being unable to feed therethrough, will cause the arms 96 and 100 torock in unison thereby rocking the latch 101 and releasing the I shifting member 7, whereupon the machine will be automatically stopped.
Immediately following the feeding operation of the strips of sheet material 18 the member 126 of the tip forming instrumentalities will engage the upper end of each of the strips 18 bending them upon the lacing A which is resting upon the work support, and while thus bent pieces of material 140 are severed from the rest of the strips and rolled around the lacing. During the operation of rolling the pieces of material 1 10 around the lacing A, the movable cutter 135 cooperating with the stationary cutting edge 137 severs the lacing between the pieces of tipping material and the lacing is then immediately engaged by the pins 138.; and
ushed into the grooves 139 thereby separatmg the severed ends of the lacing and pulling said severed ends a short distance into the interior of the tip. The member 126 now arrives at the very end of its forward movement, at which time the recess 129 thereof and the recess 132 of the tip forming member 131 with their respective grooves and ridges will all cooperate to clinch a piece of material 140 around the lacingand crimp said material thereto, thereby com-- pleting the tip. I
It should be distinctly understood that the term lacing as used in the specification and in the claims which follow designates the material of which the finished laces are composed. Also, that, while I have referred to the tipping material generally as sheet material, it is to be understood that such tipemme width suliicient to form a pair of tips.
' While I have necessarily shown and described the -preferred embodiment .of my invention somewhat in detail, it is to be understood that I may vary the size, shape, and arrangement of parts within wide limits without departing from the spirit of the invention.
