- the carrier is a-hollow box-like structure in which any suitable heater may be placed. I have here shown conventionally in side elevation an electric heater 32.
- the carrier 31 supports and moves certain-elements ef-the tip-forming mechanism hereinafter described which severs a tip blank .27 -from the strip 27, wraps said blankintubular form around frame standard said standard being bolted to the'base 25 and having hearings in Y which is journaleda cam shaft 34, one side"- 'of which is journaled in a bearing on a frame standard'25 which is also bolted to 1. the base.
- the shaft 34 is provided with a 'worm gear 35 meshing with a worm 36 on a l transverse" driving shaft 37 journaled 1n bearings on the standard 25*.
- the shaft 34 is provided with a series of cams 38, 39, and parts o'f'the t1p-.
- the cam 38 which causes the reciprocating movements of the carrier 31 has a groove 41 (Fig. 7) engaging a trundle roll.42 on a T 25 bar 43 which is movable 1n a guide in the standard25 and is provided with a rack 44 meshing with a gear segment 45 (Fig. 2) on a rock shaft 46 journaled in bearings on the base. Said rock shaft has an arm 47 which' the carrier 31.
- the cam 39 is formed to reciprocate a slide 50 carrying a shear blade 51 which cooperates with ashear blade- 52 on the car- 5 rier in severin ablank from the strip 27 as shown by Fig. 14.
- the slide 50 also carries aprimary folding blade 53 formed to coeperate with opposed faces on parts supported by the carrier 31 in imparting to the lank a trough shape (Fig. 14) preliminary to the application of the fabric to the blank.
- the cam 40 is formed to reciprocate a slide 54 which carries a secondary folding blade 55 which has a grooved face 56 adapted and operated as hereinafter described to first bend one of the edges of the trough shaped blank inwardly, as shown by Fig. 15, and afterward bend the opposite edge of the blank inwardly, as shown by Fig. 16, to
- the slides 50 and 54 are reciprocated vertically in guides in the frame standard 25, and arelocated over the path in which the carrier31 moves, so that the blades 51, 53 and 55 are ada ted to coeperate with the parts of the tip: orming mechanism next described,'mounted on the carrier.
- the shear blade 52 is formed by the intersection of the outer sideand upper edge of a member 0 "is connectedbylinks 48 with an ear 49 on "$9M flange'58 (Figs. 1, 2, e and 14 on a horizontal top plate 59 rigidly attached to The inner "side 60 of the the carrier 31. flange 58.forms one of the opposed faces between which the blank is bent to a trough h e (Fig. 14). The other of said faces is the end 61 (Fig. 20) of a slide 62 which is movable horizontally on the top plate 59,
- slide 62 moves with the carrier and has a limited movement independently thereof, so
- channel is at.its maximum width and is positioned to receive the lower portion of the folding blade 53, the shear blade 52 being ositioned to ceoperate with the reciprocat- 1n shear blade 51.
- the carrier is held in this position while the 'slide 50 descends and causes the severance of a blank from the strip 27 by the shear blade, and the insertion of the blank in thechanneL 64 by the folding blade 53, the blank being given a trough shape by the sides of the channel and by the blade.
- the slide 50 then rises and the carrier is moved outwardly 'to the position shown by Fig. 15, the channel beingnow under the secondary folding blade 55, and the channel face 61 substantially in alinement with the outer side of said blade. While the carrier is in this position the operator deposits the portion of a lacing fabric around which the blank is to be wrapped, in the trough formed by the partly folded,
- the secondary folding blade 55 entering the channel atone sideof the center thereof so that its grooved edge 56 engages one of the lips or sides of the troughformed by the partially folded blank and rolls said lip over upon the fabric, as shown by Fig. 15.
- the plunger 54 is then raised and the carrier is given a slightjoutward movement to the position shown by Fig. 16, the slide 62 and its face 61 being at this time arrested by a fixed stop 66 (Fig. 2) attached to the base 25 so that the face 61 remains in the position shown by Fig.15.
- the last described movement of the "carrier therefore moves the face 60 toward the face"61'. and decreases the width of the channel 64, the face 60'being now substantially in alinement. with the .inner side of the secondary folding blade.
- the slide 54 now again descends and engages the'other lip of the partially folded blank, rolling it over upon the previously rolled lip and completing the the tube, as shown by Fig. 16.
- a duct 67 (Figs. 4 and 6) in the frame standard 25 sa1d duct comormation of municat-ing with a cup 68 which is intermittently charged with alcohol from a reservoir 69 by automatic means hereinafter described, the duct 67 being provided with a needle valve 7 O which is opened by the ascent of the blade 55, and allows the charge in the cup 68, or a portion thereof, to fall upon the upper edge of the blade, from which it fiows downwardly upon the sides of the blade to its lower edge.
- the quantity of alcohol thus supplied is sufficient to'coat the entire lower edge of the blade 55, and soften the portions of the blank with which said edge comes in contact. This softening of the tip material, together with the pressure exerted upon it by the secondary folding blade, and the heat imparted to the faces 60 and 61, as well as to the blade 55 by the heater, insures the formation of a permanent tube 27 b which closely embraces the inclosed portion of the lacing fabric.
- the solvent is so applied as to coat the entire lower edge of the blade 55. Therefore when said blade descends, it

In the drawings,25 represents a frame base having a horizontal bed 26 on which a strip 27 of sheet celluloid or other like pyroxylin material is moved intermittently by feed rolls 28, 29, rotated step-by-step the bed having an opening 30 (Fig. 2) which receives the upper portion of the lower feed As here shown, the carrier is a-hollow box-like structure in which any suitable heater may be placed. I have here shown conventionally in side elevation an electric heater 32. The carrier 31 supports and moves certain-elements ef-the tip-forming mechanism hereinafter described which severs a tip blank .27 -from the strip 27, wraps said blankintubular form around frame standard said standard being bolted to the'base 25 and having hearings in Y which is journaleda cam shaft 34, one side"- 'of which is journaled in a bearing on a frame standard'25 which is also bolted to 1. the base. The shaft 34 is provided with a 'worm gear 35 meshing with a worm 36 on a l transverse" driving shaft 37 journaled 1n bearings on the standard 25*. The shaft 34 is provided with a series of cams 38, 39, and parts o'f'the t1p-.
2.0 :40 which actuate different forming mechanism.
' The cam 38 which causes the reciprocating movements of the carrier 31 has a groove 41 (Fig. 7) engaging a trundle roll.42 on a T 25 bar 43 which is movable 1n a guide in the standard25 and is provided with a rack 44 meshing with a gear segment 45 (Fig. 2) on a rock shaft 46 journaled in bearings on the base. Said rock shaft has an arm 47 which' the carrier 31.
The cam 39 is formed to reciprocate a slide 50 carrying a shear blade 51 which cooperates with ashear blade- 52 on the car- 5 rier in severin ablank from the strip 27 as shown by Fig. 14. The slide 50 also carries aprimary folding blade 53 formed to coeperate with opposed faces on parts suported by the carrier 31 in imparting to the lank a trough shape (Fig. 14) preliminary to the application of the fabric to the blank. The cam 40 is formed to reciprocate a slide 54 which carries a secondary folding blade 55 which has a grooved face 56 adapted and operated as hereinafter described to first bend one of the edges of the trough shaped blank inwardly, as shown by Fig. 15, and afterward bend the opposite edge of the blank inwardly, as shown by Fig. 16, to
50 complete the formation of the tube 27".
' The slides 50 and 54 are reciprocated vertically in guides in the frame standard 25, and arelocated over the path in which the carrier31 moves, so that the blades 51, 53 and 55 are ada ted to coeperate with the parts of the tip: orming mechanism next described,'mounted on the carrier. The shear blade 52 is formed by the intersection of the outer sideand upper edge of a member 0 "is connectedbylinks 48 with an ear 49 on "$9M flange'58 (Figs. 1, 2, e and 14 on a horizontal top plate 59 rigidly attached to The inner "side 60 of the the carrier 31. flange 58.forms one of the opposed faces between which the blank is bent to a trough h e (Fig. 14). The other of said faces is the end 61 (Fig. 20) of a slide 62 which is movable horizontally on the top plate 59,
and moves in a fixed path therewith. The
- that the faces 60 and 61 constitute sides of a channel 64 (Fig. 14) of; variable width. When the carrier is at the inward extreme of its movement, as indicated by Fig. 14, the
channel is at.its maximum width and is positioned to receive the lower portion of the folding blade 53, the shear blade 52 being ositioned to ceoperate with the reciprocat- 1n shear blade 51. The carrier is held in this position while the 'slide 50 descends and causes the severance of a blank from the strip 27 by the shear blade, and the insertion of the blank in thechanneL 64 by the folding blade 53, the blank being given a trough shape by the sides of the channel and by the blade. The slide 50 then rises and the carrier is moved outwardly 'to the position shown by Fig. 15, the channel beingnow under the secondary folding blade 55, and the channel face 61 substantially in alinement with the outer side of said blade. While the carrier is in this position the operator deposits the portion of a lacing fabric around which the blank is to be wrapped, in the trough formed by the partly folded,
blank. The carrier is held in the last-de-;
scribed position while the slide 54 descends,
the secondary folding blade 55 entering the channel atone sideof the center thereof so that its grooved edge 56 engages one of the lips or sides of the troughformed by the partially folded blank and rolls said lip over upon the fabric, as shown by Fig. 15. The plunger 54 is then raised and the carrier is given a slightjoutward movement to the position shown by Fig. 16, the slide 62 and its face 61 being at this time arrested by a fixed stop 66 (Fig. 2) attached to the base 25 so that the face 61 remains in the position shown by Fig.15. The last described movement of the "carrier therefore moves the face 60 toward the face"61'. and decreases the width of the channel 64, the face 60'being now substantially in alinement. with the .inner side of the secondary folding blade.
The slide 54 now again descends and engages the'other lip of the partially folded blank, rolling it over upon the previously rolled lip and completing the the tube, as shown by Fig. 16.
Prior to each descent of the secondary folding blade 55, a'small'quantity of alcohol.
or other liquid which; is a softener or solvent of celluloid is discharged upon the back'of said blade, through a duct 67 (Figs. 4 and 6) in the frame standard 25 sa1d duct comormation of municat-ing with a cup 68 which is intermittently charged with alcohol from a reservoir 69 by automatic means hereinafter described, the duct 67 being provided with a needle valve 7 O which is opened by the ascent of the blade 55, and allows the charge in the cup 68, or a portion thereof, to fall upon the upper edge of the blade, from which it fiows downwardly upon the sides of the blade to its lower edge. The quantity of alcohol thus supplied is sufficient to'coat the entire lower edge of the blade 55, and soften the portions of the blank with which said edge comes in contact. This softening of the tip material, together with the pressure exerted upon it by the secondary folding blade, and the heat imparted to the faces 60 and 61, as well as to the blade 55 by the heater, insures the formation of a permanent tube 27 b which closely embraces the inclosed portion of the lacing fabric.
As mentioned, the solvent is so applied as to coat the entire lower edge of the blade 55. Therefore when said blade descends, it
causes the solvent to permeate the entire? less or integral throughout, and capable of withstanding the effort of the fabric to expand from a condition of extremely compressed and small cylindrical form.
The tube 27 and the inclosed fabric are next severed transversely at the center of the length of the tube to form tipped ends of two laces, by a knife blade 72 having a notch, one end of which is sharpened to form a cutting edge 73.
The blade is attached to a shank 74 which is movable endwise in a guide (Fig. 18) in the top plate 59, and is normally held-in the position shown Fig. 2 by a spring 76 interposed between a shoulder 77 (Fig. 17) of the top plate, and a pin 78 on said shank. The spring holds one end of the blade 72 against a stop screw 79 on the slide 62 and projects the outer end of the shank 74: yield ingly from the outer end of the top plate 59, as shown by Fig. 2. The "stop 79 causes the knife to move in unison" with the slide 62 excepting when a stop 80 on an oscillatory arm (Fig. 7) is moved into the path of the shank 74:, as shown by Fig. 17. 'The stop 80 is normally at one side of the'path of the shank,'as indicated by Fig. 7, and is moved into and out of said path by means hereinafter described. The stop is held out ofthe path of the knife shank during the above described steps of the tip-forming operation,
and is moved into the path of the shank -Inentioned position when the stop 80 is in the path of the knife shank, causes the stop to arrest the movement of the knife 72 in the same direction, so that the completed tube is forced by the face 60 against and across the cutting edge 73 of the knife, as shown by Fig. .17, the tube and the fabric inclo-sed therein being thus severed, and two tipped lacing ends formed. The stop 80 is then moved outof the path of the knife shank and the knife is returned by the spring to the position shown by Fig. 2, when the machine is in readiness for a repetition of the operations above described.
As indicated by Figs. 17, 18, 19 and 20, the top plate 59 and its flange 58 are provided with a slot 83 to receive and guide the knife blade, while the slide 62 is provided with a slot 84: for the same purpose, said slots being in alinement with eac other. The slide 62 is provided with a stud 83 which projects into a slot 85, Figs. 10 and 12. The carrier topplate 59 has a stop screw 84 which projects into said slot and is adapted to bear on the stud 83 and move the slide 62 with the carrier when the carrier is moving inwardor toward the feed rolls. When the carrier is moving outward, or in the opposite direction, the slot 85 permits a limited movement of the carrier independently ofthe top-plate, the latter remaining stationary until the inner end of the slot abuts against the stud 88, as indi cated by dotted lines, Fig. 12. The spring 76 which retracts the severing knife, also acts through the heel of the knife and the stop 79 (against which said heel normally bears, as shown by Fig. 2,) to force the slide 62 outward as far as the stop 84? will permit, provision being thus made for yieldingly maintaining the channel 64: at the maximum width shown by Fig. 14. Provision is thus made for the varying relative positions of the slide and the carrier, and therefore of the faces 60 and 61, shown by Figs. 14, 15, 16 and 17. The cam groove 41 is formed, as shown by Fig. 7, to impart the above described movements to the carrier, said movements being stepby-step and the carrier being held stationary for a suitable period after each movement.
Adjustable "stop screws .87 (Fig. 10) are provided to limit the outward movement of the carrier, said stops being secured to the base 25 and arranged to abut against gib's gaged with the base 25.
blade 52nwith relation to the upper. shear blade 51. To this end,the lug 49 is provided with a cavity in which is fitted a block 91 (Fig. 13) through which passes the pin 92 which\.connects the links 48 with the lug 49. The lug 49 is also provided with studs having screw-threaded portions 93 engaged with the threaded sockets in the lower portion ofthe arm and eccentric portions 94. hearing on opposite sides of'the block. By rotating the studs, the eccentric portions 94 are shifted laterally and slightly vary the position of the lug 49 relatively to the pin 92. The lug 49 is provided with a slot 95 through which the pin 92 passes.
The arm 81, carrying the knife-operating stop 80, is attached to a rock shaft 96 (Figs. 7 and 8) journaled in bearings on the base 25. Said rock shaft is provided with a bent arm 97 (Figs. land 7) having a trundle .roll 98 at its outer end adapted to be engaged by a projection 99 on the cam 38, said projection being preferably a resilient spring arm having a shank 100 secured to one side of the cam 38, as indicated by Fig.
7. A spring 101 (Fig. 8) attached at one end to the rock shaft 96, and at the other end to the base 25, holds the rock shaft and its arms 81 and 97 normally in the .position shown by Fig. 7, the stop 80 being out of the path of the knife shank 74, and the trundle roll 98 in the path of the projection 99.
When the rotation of' the cam 38 brings the cam projection 99 to the trundle roll -98 the arm 97 is moved by said projection ("valve is provided with an arm 104 which is and turns the rock shaft 96 sufliciently to move the stop into the path of the shank 74, thus causing the above described operation of the knife.
The reservoir 69, containing a supply of alcohol, is provided with an outlet 102 (Fig. 4) which includes a casing 103 containing a valve adapted to be oscillated on a vertical axis, and to alternately open and 'close the outlet, the delivering end of which coincides with the cup 68. The stem of the adapted to be oscillated to open and close the valve, and is normally held by a spring 105 in position to close the valve. -The hub of the cam 40 is provided with cam wings 106 and 107 which are separated from each ing each upward movement of said folder.
The preferred form of the cam 39 is that shown by Fig. 5, said cam having a concentric portion occupying the greater part of its perimeter and a short cam groove 39 which engages a trundle roll 50 on the slide 50, and is formed to impart the described movements to the upper shear blade 51 and the primary folding blade 53. The preferred form of the cam 40 is that shown by Fig. 6, said cam having two cam grooves 4O and 40 which coiiperate with a trundle roll 54 on the slide 54, in imparting the above described movements to the secondary folding blade 55.
The lower feed roll 28 is reciprocated step-by-step by suitable mechanisnn'preferably that shownby Figs. 2, 3 and 9, said mechanism comprising a connecting rod 108 engaged at one end with the carrier, a.
lever 109 engaged with the opposite end of the rod 108 and mounted to oscillate on the 7 shaft 110 of' the lower feed roll, a pair of pawls 111, 112 pivoted to the lever 109, and a ratchet 113 attached to the feed roll 28.
The rod 108 is reciprocated by the -moveadapted to turn thelatter in either direction on the shaft 110. The upper feed roll 29 is mounted in yielding bearings which are pressed downwardly by springs, as shown by Fig. 3, so that the upper roll is pressed yieldingly against the strip 27interposed' between it and the lower roll, the
two feed rolls being connected by gears 121,
122, (Fig. 3). Q
The upper shear blade 51 and the lower shear blade 52 above described are adapted to form a rectangu' amblank 27 of the form shown by Fig. 23, this blank forming-a cyi lindrical tube 27 as shown'by Fig. 25.
The driving shaft 37 is preferably driven by a belt running on a pulley 117, said pulley being loose on the shaft and adapted to be connected therewith by a clutch 118 controlled by a treadle (not shown) through a rod 119 and a bell crank 120 (Fig. 4c).
Whenthe tube is to be given a double frusto-conical form, as shown by Fig. 26, a an upper shear blade 51 of the form shown by Fig. 22 is employed, said blade having two obtuse angle cutting edges 51 and 51 i strip 27 is utilized as acutting edge 52 (Fig. 22), which is recessed to cooperate with the cut-ting edge 51. At each descent of the upper shear blade 51 the cutting edges 51 and 52 form an angular edge 27 and the cutting edges 51 'and 52 form an angular edge 27. The feed movement of the strip 27 is longer than is the case when a blank with parallel edges is formed, the edge 27, which is the forward end of the strip, being advanced by each feed movement a distance equal to the width of the blank plus the thickness" of the shear blade 51, so that a portion of the strip between each blank and the next becomes waste ma- 30 terial as indicated by dotted lines, Fig. 27 The acting edge or end of the secondary folding blade 55 used in making frustoconical tips is formed as shown by Fig. 28.
The stop screws 66 and 87 enable the limits of the outward movements of the carrier 31 and of the slide 62 to be adjusted independently to vary the width of the channel 64, and enable tips of difierent diameters to be formed. When the machine is adfi'justed to change the diameter of the tips, the secondary folding blade 55, previously lused, will be removed, and another blade of greater or less thickness substituted for 1t, according as the diameter is to be increased or decreased.
It is obvious that any suitable flexible material may be employed for the lacing tips, and while I prefer a pyro-Xylin material such as celluloid, other or equivalent flexible 550 sheet material may be used. The recently invented material known as celum which is analogous to celluloid but is relatively non-combustible, may be employed.
By the term celluloid employed herein, I do not mean to restrict myself to any one species of pyroxylin as the material employed, although at present I consider celluloid as the best substance for the purpose. Any material in sheet form and capable of 6% being cutto form the blanks and then folded or wrapped around the lacing fabric, while its inner surface is so softened as to be unitedto the fabric by pressure, and to have its contacting edges so combined as to leave the sheath orwrapping practically seamless,
is to be understood as included by the term celluloid.
