SPECIFICATION ,forming part of Letters Patent- N o. 701,178, dated lV-Iay27, 1902.

application filed April l 51 1 9 0 l f To a/ZZ whom, it' may concern:

Be it known that I, NAPOLEON DUssAULT, a citizen of the United States of America, residing in the city and district of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Nail- Making Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in nail-machines; and one object thereof is the provision of a simple, efficient, and automatic machine adapted to the work ofpointing and heading nails, so as to produce them in a continuous strip or, as it has been termed, a string, although the machine may be adapted to the manufacture of detached nails.

A further object of the invention is to provide a novel form of the header mechanism by which the nail-heads of a strip or string may easily and rapidly be produced owing to a peculiar movement imparted to the heading-dies.

A further object of the invention is to provide a novel shaping and pointing mechanism arranged to give the desired taperedform and penetrating point by compression of the wire stock at proper intervals as distinguished from a filing, cutting, or other Asimilar operation involving` transverse abrasion` of the metal, thus producinga more solid and generally superior article.

A further object of the invention'is to im` prove the construction of the 'header mechanism with a view to securing 'rapidity in opening the dies, to the end that ample clearance will be provided for the nail-heads and the stock may be properlyyand'unobstructedly fed through the machine.

Further objects of the invention are to provide a simple feed mechanism for the stock material, to provide'foi" adjustment of the header mechanism and of the feed mechanism, so as to make nails which may vary in length, to simplify the construction, and to arrange the parts so as to secure high speed and maximum efficiency in service, thus increasing the daily output of the machine.

With these ends in view the invention consists in the novel combination of mechanisms Serial No. 55,804. (No model.)

and in the construction and arrangement of the'various parts for service, which Will be hereinafter fully described and claimed.

' In the drawings hereto annexed, forming a part of this specification, Figure 1 is a plan view of a nail-machine embodying my invention. Fig. 2 is a sectional side elevation thereof. Fig. 3 is an elevation looking at one end of the machine to show the Worm-gearing for driving the reel or spool. Fig. 4 isa vertical cross-section on the line 4 4 of Fig. 2 looking in the direction of the arrow. Figs. 5 and 6 are vertical cross-sections in the planes 4of the dotted lines 5 5 and 6 6, respectively, on Fig. 2, each view looking in the direction of the arrow. Figs. 7 and `8 are detail cross-sectional views on the lines '7 '7 and 8 8, respectively, on Fig. 6. Fig. 9 is a detail view of a part of the feed mechanism. Fig. lO-is a cross-sectionon the line 10 10 of Fig. 2 looking inthe direction ofthe arrow. Fig. 11 is an enlarged perspective view of the header lever removed from the machine. Fig. 12 is a similar view of the lever for the movable pointing or ,forming die. Fig. 13 is another perspective view which illustrates the means for supporting the stationary pointing or forming die. Fig. 14 is a detail view of the nail-strip or string-nails' produced by the machine. Figs. 15, 16, and 17 are enlarged detail viewsillustrating the various positions of the dies during the operations of feeding the stock material, compressing the latter at predetermined regular intervals, so as to produce the desired shape and point to the nails, and of forming the heads on the nails individually, so as to produce the "ded sired string of nails.

The same numerals of reference denote like parts in each of the several figures of the drawings. f

5 designates the horizontal bed or table, which is supportedat a` proper elevation by a skeleton framework 6, the latter 1being erected uponorforming a part of the column 7. This framework may be of any desired character, and I do not, therefore, restrict myself to the particular construction herein shown as one means for supporting the operative parts of the machine. From opposite end portions of the table depend the hangers 8 S, having suitable journabbearings for thc IOO accommodation of the horizontal drivingshaft 9, said shaft extending at one end beyond the frame for the reception of the fast pulley 10, the loose pulley 11, and the balance-wheel 12. An inclined standard 13 extends upwardly from the other end portion of the bed or table, and in a suitable shaftbearing on said standard is arranged the spool-shaft 16, the latter carrying the spool or drum 17, on which is coiled the strip of continuous nails manufactured by the machine from a single strand of stock material, such as wire. The drum or spool 17 is made fast with the shaft 16, which is supported by the standard in an elevated horizontal position above the table or bed, and on this shaft 16 is firmly secured a driving-pulley 18,around which passes a crossed belt 19, which also encompasses a driving-pulley 20. Said {pulley ismlade fast with a horizontal counter-shaft 21, that-is arranged at right angles to the main shaft 9, preferably below the latter. This counter-shaft is journaled in a proper bearing 22 of a bracket-23, whichis shown by Fig. 3 as forming a part of one of the hangers 8. One end portion of this counter-shaft 21 terminates below the main shaft 9, and on thislast-named shaft is formed or secured a worm-screw 24, the same arranged to have intermeshing engagelnent with a worm-gear 25, which is made .fast withy the counter-shaft. The,rotation of the main shaft 9 turns the .worm-screw 24, which in turn propels the counter-shaft 21 through the worm-gear 25, and'this shaft drives thepulley 20, the belt 19, and the pulley 18, whereby the shaft 16 is positively driven in order to wind the strip of ynails on the spool or drum 17 as rapidly as Vrate Vthe two slots 26 27.

the nail-stripv is produced by the machine.

The table 5 is provided with a short longitudinal slot 26, another longitudinal slot 27, andga cross-bar 28, thelatter serving to sepa- On this cross-bar is arrangedthe die-block 29, the same being shown in detail by Fig. 13. Said die-block is provided y.with the parallel wings 30, which are disposed-,on opposite sides of the block l and are joined thereto by the base-plate 31,

from which depends the stem 32, that is arranged to pass through an opening 33 of the cross-bar, as shown by Fig. 2. A nut 34 is screwed on a threaded lower portion of the stem 32 and is adapted to fasten the die-block in a stationary position onv the bed 5, one of the vertical faces of this die-block being in flush relatiou'to an edge of the cross-bar 28.

Thewin gs 30 are parallel to the lateral faces of the die-block 29, so that the parts will be spaced to provide openings or recesses adapted to` receive the underportion of the irregularly'curved or shaped die-lever 35, (shown moreclearly by Figs. 2 and 12,) and through ,-thewings, the die-block, and the lever passes a pivotal shaft or bolt 36, whereby said lever 35 is fulcrumed on the stationary die-block. Thedie-block 29 is provided, furthermore, with an npstanding lug 37, in which is produced a guide-opening 38, and, furthermore, Y

the portion of the die-block which is opposite to the feeder-lever, to be presently described, is recessed or cut away at 39 in Figs. 2 and 13, so as to provide a space for the feeder-plate on the feeder-lever to work therein, all as will hereinafter appear. Finally, the vertical face of the die-block 29, which is flush with one edge of the bar 28, is provided with a dovetailed guideway 40, in which is fitted the lower stationary die of the pair of coacting shapingdies 41 42. The lower shaping-die 42 rests in a dovetailed guideway of the die-block 29, so as to be supported normally in operative position by a ledge or shoulder of said die-block, as clearly shown by Fig. 2, the upper operative end of said stationary shaping-die being presented in the path of the wire or other stock material as it passes through the lug 37 of the die-block 29.

The shaping-die lever 35 is arranged ina generally-inclined position, so as to have its lower portion arranged and free to Work in the slot 27 of the bed 5, and this lever is fulcrumed at a point intermediate of its length on the stationary die-block 29 and its wings 30 by the pivotal shaft or arbor 36. The other upper portion of this shaping-die lever is extended in a vertical direction, as shown b vFig. 2, above the fulcrum 36 thereof, and in this upstanding extremity of the lever is a dovetailed guideway 43, the same receiving the upper movable shaping-die 41, which is'held in position adjustably in the lever 35 by suitable clamping and adjusting screws 44 45. The screw or screws 44 is adapted to impinge a side edge of the die 41, while the other screw 45 engages with the upper end of the die -for the purpose of giving adjustment to the die in a vertical direction, whereby the upper die may be adjusted to bring the working faces of the pair of coacting shaping-dies into operative relation. These dies 41 42 are provided in their opposing edges or faces with the tapering grooves or channels 46, which are arranged to register with each other, as shown by Figs. 15 to 17, inclusive, and which form a tapered passage on closure of the dies, the greatest diameter of which passage is on the receiving side of the dies just next to the feed mechanism.

The shaping-die lever 35 is provided with the longitudinal slot 35, by which it is adapted to receive the fixed die-block 29, thus making provision' for compact assemblage of the lever 35 and said die-block. r1he lower end of this lever carries a shoe 47 in the form of a friction-wheel, which is loosely mounted thereon, as shownV by Fig. 2, and this shoe is adapted to ride upon the periphery of a cam 48, the latter being firmly secured to the shaft 9 for rotation therewith. This cam is provided with two high points arranged to successively engage with the shoe 47 and to ac- IOI) IXO

equipped with an ordinary straightener mechanism, which is adapted to take the crimp out of the wire as it isfed to the machine and to serve as the means for automatically straightening the Wire before it is passed by the feed mechanism to the shaping and heading mechanisms. This straightener mechanism contemplates the employment of a base-plate 49, which is secured in a horizontal stationary position above the bed 5, and on this plate are the series of grooved rolls 50, arranged in groups on opposite sides of the line of feed of the stock material and adapted to engage therewith.

I will now proceed to describe the feed mechanism, which has its operative parts disposedV between the straightener mechanism and the elements of the shaping-die mechanism. An essential part of this feed mechanism is the upright feeder-lever 5l, which is arranged to play in the slot 27 of the table and the slot of the shaping-die lever 35. This feederlever extends in a downward direction past the main shaft 9, and it is bent at a point intermediate of its length, as at 52, (see Fig. 5,) in order that the lower portion of the feederlever may be disposed in a different vertical plane from the upper portion of the same lever. This bending of the feeder-lever enables its lower portion to clear the main shaft 9, while its upper portion is disposed close to the path of feed of the stock material or wire, whereby the feeder-lever is adapted to support the wire-engaging devices in proper position for operation. The lower portion of .said feeder-lever is fulcrumed by a bolt or pin 53 to a stationary bracket 54, the latter being supported by the framework or the column. A shoe-supporting bracket 55 is secured firmly to the feeder-lever, adjacent to the bend 52 therein, and in this bracket is journaled a shoe or roller 56, the same being free to turn on a vertical axis and disposed in the path of the high point on a rotary cam 57, the latter being fast with the shaft 9 and disposed adjacent to the cam 4S, which actuates the shaping-die lever 35. The feeder-lever is limited in its movement in one direction by means of an adjustable stop-rod 58, the latter being loosely fitted in a short post 59, which is made fast to the bed 5 and serves to support the straightener-plate 49. This stop-rod is secured adj ustably to the post by a clamping-screw 60, and the end of the stop-rod lies in the path of the feederlever 5l. A coiled retracting-spring 6l is fitted loosely on the adjustable rod, one end of the spring being attached to the post 59 and the other end thereof being secured to the feeder-lever, as shown by Figs. 2 and 9, whereby the spring is arranged to normally pull the feeder-lever toward the stop-rod and maintain the shoe 56 in the path of the feeder-actuating cam 57.

The feeder-lever has its upper portion extended above the path of the wire or stock material which passes through the straightener, and in said upper portion of this lever is loosely mounted a short pin or bolt 62. Through an enlarged portion of this pin or bolt is an opening that accommodates the feed-finger 63, which is held securely to the .rocking pin by a set-screw 64. (See Fig. 5.) This pin 62 is mounted in the feeder-lever, so as to rock or turn on a horizontal axis, while the finger 63 is arranged in an inclined position, so as to engage with the top edge of the wire or stock material. This finger is kept in its operative position by the energy of a coiled retracting-spring 65, one end of which is attached to the feeder-lever, while the other end is secured to an arm 66, which extends outwardly from the rocking pin or bolt, as shown by Fig. 9. A feed-plate 67 is secured firmly to the feeder-lever and disposed in a horizontal position just below, but very close, the path of feed of the Wire or stock mate rial. This feed-plate projects from the lever 5l into the space or recess 39 of the die-block, (see Fig. 2,) and this feed-plate is thus mounted on the feeder-lever to partake of the vibrations thereof, and itis maintained at all times in operative relation to the working end of the spring-actuated feed-finger 63. The energy of the spring is sufficient to make the finger 63 and the plate 67 engage with the wire by frictional contact and feed thelat- .ter to and through the shaping-die when all the dies are open and the proper movement is given to the feeder-lever by the cam 57; Jbut when the dies (one or both sets) are firmly engaged with the wire, the feeder-lever may be restored to its position by the retractile energy of the spring 65, whereby the feederlever is positively moved by the cam in a direction to advance the wire; but the return movement of the feeder-lever to its initial position is effected by a spring, the finger 63 slipping idly over the Wire during such return movement of the feeder-lever.

68 designates a swinging frame normally arranged in a horizontal position above the slot 26 in the bed 5, said frame consisting of parallel side bars united by an intermediate cross-bar, as shown by Fig. l. A pivotalarbor 69 passes through one end of the frame, and the end portions of said pivotal arbor are iitted in vertical slots 70, which are formed in the bearing-blocks 7l 7l, the latter being firmly secured on the table 5 at one side of theslot 26 and serving to hingedly connect the swinging frame to said table. The pivotal arbor 69 is capable of adjustment in a horizontal direction by means of the opposing set-screws 72 73, which are mounted in the bearing-blocks on opposite sides of the arborand are arranged to engage therewith so as to shift the arbor to different positionswith respect to the bearing-blocks forapurposewhich will hereinafter appear. Through the inner portion of the swinging frame which overhangs the slot 26 and the table 5 loosely passes the upper portion of the header-lever 75, the same being shown more clearly by Fig. ll.

desired adjustment to the upper die 85.

Said header-leveris fulcrumed at a point intermediate ofits length in the free portion of the swinging frame, by the transverse rod or arbor 76, whichy passes through said -frame andthe header-lever, wherebythe arbor 76 and-the swinging frame serve as a shifting fulcrum for the header-lever. The utility of this construction and.- arrangement will .f appear in connection with the description of the yheader-dies.

The header-lever is disposed normally in a vertical position, so as to extend through the slot 2.6. of 1' the, bed and to extend intok the frame. The lower portion of saidV lever is formed with the ring or annulus 77, through which the shaft- 9 is free to pass, andthis ring-or annulus is of such a diameter as to permit the lever to have the desired movementwithoutengagingwiththeshaft. Above this ring the header-leveris provided with a longitudinal way 7 8.for a cam-actuated .slide 79,-the way and the slide being ,dovetailed in cross-section, as shown by Fig. 8. Furthermore., theupper extremity of the lever7 5 has a lateral offset 80, the same being formed with .a die socket 8l and provided with clamping and adjusting screws 82 83. The slide 79 is free to haverectilinear reciprocating movement in the guideway of the headerlever, and said slide is provided at its upper portionwithl a die-socket 81, thesame being dovetailed in cross-section and terminating in a lip or shoulderBLla.

f 86 designate-the coacting header-dies, whichare mounted inthe ,die-sockets 8l 84, respectively. The upper header-die 85 is engaged by the clamping-screw 82, so as to be held in ,position thereby, although the clamping-screw may be-released .and the screw 83 lmaybe rotated for ,the purpose of giving a The other or lower header-die 86 is litted 4in the socket 84,l so` as to rest upon the` ledge or shoulder 84, and said lower die 86 may be held securelyin position bya clamping-screw 87. (See Fig. 8.),y The .active ends of the two header-dies 8586 are formed-with the grooves 88, which areinclined across the faces of the dies and arranged in position to match or register with each other, and the receiving ends of these-grooves are enlarged slightly, as at 89, while the delivery-faces of the dies are formed with enlarged clearance-recesses 90. The grooved working faces 88 of the coac-tng operating-dies conform to the active endsof Lthe shaping-dies, so thatthe headerdie mayfrmly engage with the work after the shaping-dies shall have given the desired shape or taper thereto; but the head-forming enlargements 89 ofthe header-dies are adapted to allow the upset metal to enter therein ,when the pair of closed header-dies are moved positively toward the closed shaping-dies for the purpose of forming the head of one nail constituting the strip or string of nails.` The recesses 90 at the back face of the headerdies allow ample clearance for the head of shown by Fig. 2.

the newly-formed nail constituting one of the string. (See Figs. 15 to 17, inclusive.)

The lower portion of the slide7 9 is provided with a roller-shoe 91, which is loosely mounted on a pin 92, that is attached to the slide, whereby the roller-shoe is disposed above the annu- {lar opening 77 of the header-lever. This shoe 91 of the slide is arranged to ride upon a cam 93, which is made fast with the main shaft 9 and is adapted lto positively lift the slide 79 ;for the purpose of closing the dies 85 86. The lower portion of the header-lever is provided with a bolt 94, on whichl is loosely `mounted a roller-shoe 95, the same arranged below the annular opening 77 of said lever and arranged to ride upon the lower portion of the cam 93. The lower portion of the headerlever is furthermore provided with an angular outstanding bracket 96, the same extending beyond the roller-shoe 95 and supporting another roller-shoe 97, the same arranged to irotate on a vertical axis and presented in operative relation to the high parts of a cam 98, which is made fast with the main shaft9at a pointadjacent to the other cam 93, as clearly A retracting-spring 99 has one end connected by a link 100 to the lower portion of the header-lever, the other end of said spring being connected to an opstanding 'arm 101 on a plate 102, which is fastened 'adjustably by the bolt 103 to the frame of the column. This spring. 99 is adapted to "pull the lower portion of the header-lever tolward the cam 98 in order that the horizontal roller-shoe 97 may ride against the face of the header-lever-actuating cam 98.A

y From the foregoing description, taken in connection with the drawings, it will be noted that the roller-shoe 91 of the header-slide 79 and the roller-shoe 95 of the header-lever are arranged to ride against the opposite portions of aheader-actuatin g cam 93, and these rollershoes are caused to follow the movement of the cam by means of a powerful bent spring 104, the same having one end portion attached to the header-lever, as clearly shown by Fig. 2. The, tendency of the spring is normally to impel the slide in a downward direction and to lift the header-lever in an upward direction, whereby the roller-shoes are made to ride against the cam. Furthermore, it will lbe observed that the upper header-die 85 is mounted directly onthe header-lever,whereas ythe lower header-die 86 is supported indirectly on the header-lever through the medium `of the header-slide 79, whereby both of the header-dies are adapted to travel with the header-lever when the latter is moved on a horizontal axis by the action of the headerlever actuating cam 98; but at the same time the lower header-die 86 and the headerslide 79 are capable of a limited movement in a vertical path, such limited movement being independent of the to-and-fro movements of the header-lever. The independent movement of the lower headerdie 86 and the slide 79 under the action of the IOO ITO

cam 93 eifects the opening and closing of the coacting header-dies, whereby they are made to firmly grip and release the work, and the movement of the header-lever, with the two header-dies thereon, toward the pair of relatively stationary coacting shaping-dies 41 42 has the effect of upsetting the metal of the wire at a predetermined point, whereby the head is formed automatically on the wire or the embryo nail of the string. On opening the pair of shaping-dies and the pair of header-dies the feed mechanism becomes active to advance the wire a distance slightly greater than the length of the nail about to be formed, and one of the problems which has presented itself in the production of this machine is to secure ample clearance for the head of the nail through and between the header-dies. This problem has been solved in the present invention by mounting the header-lever on'a shiftable fulcrum which is aorded by the swinging frame and by the employment of a spring, such as 104, which has a tendency to impart aslight upward impulse to the header-lever and to the upper header-die S5 when the header-lever moves backward to its normal position from the heading position, whereby the spring 104 serves to quickly separate the two headerdies S5 S6, thus making provision for the easy passage of the nail-head through and between the dies.

The header-lever is provided with a transverse opening 105 and with a bell 106, through which the spring-nails are free to pass on their way to the windingdrnm or spool.

By making the stop-rod 5S adjustable with relation to the feeder-lever the amplitude of the stroke of said feeder-lever may be varied for the purpose of increasing or decreasing the length of the nails. The adjustment of the pivotal arbor 69 for the swinging frame, which affords the shiftable fulcrum for the header-lever, also allows the parts to be adapted for making nails which may Vary in length, and the adjustment of the plate 102 provides for variation in the strength of the spring 99, that normally draws the headerlever 97 into the path of the header-actuating cam 98.

The operation of the machine may be briefly summarized as follows, reference being had more particularly to Figs. 15, 16, and 17: Vith the two sets of shaping-dies and heading-dies in the open position (shown by Fig. 15) the cam 57 rides against the frictionroller 56, so as to impel the feeder-lever 5l toward the stationary die-block, and the feedplate 67 and the feed-linger 63 cooperate one with the other in gripping the wire, so as to advance the latter a distance slightly greater than the nail about to be formed, this excess in the length of the wire over the length of the embryo nail allowing for the upsetting of the wire necessary to formV the nail-head. Immediately after the advancement of the wire by the action of the feed mechanism the cam 48 becomes active, so as to move the lel ver 53 and the upper shaping-die 4l in a downward direction, thereby closing the pair of shaping-dies 41 42 (see Fig. 16) upon the material with such force and pressure as to compress the material for a given length thereof and produce the desired shape and taper to the nail by compression of the stock instead of cutting, abrading, or otherwise removing the material, which would have a tendency to weaken the product, whereby an improved product is produced, because the wire is compressed to the desired tapered appearance. The roller-shoe 47 of the shapingdie lever rides upon the cam 4S for a period to hold the shaping-dies 41 42 gripped upon the material during the period of operation of the header-dies to upset the material. The cam 93 actuates the roller-shoe 91 of the slide 79, so as to close the header firmly upon a previously-shaped portion of the wire, and the cam 98 also rides against the roller-shoe 97, so as to move the header-lever in a direction contrary to that of the line of feed of the material under the action of the feed mechanism. This movement of the header-lever is toward the set of relativelystationary shaping-dies. Such movement takes place when the header-dies are firmly gripped upon the material, and the header-dies and the headerlever are actuated simultaneously, so as to make the header-dies assume the close position to the shapingdies, (indicated more clearly by Fig. 17,) whereby the metal is upset and enters the recesses 8.9,in the header dies, so as to complete the formation of the nail. All the dies are now opened quickly by the roller-shoes riding upon the let-off portions of the cams, so that said dies will return to the position shown by Fig. 15, the headerdies and the header-lever 75 partaking of the peculiar movement heretofore described, so as to afford ample clearance to the passage of the nail-heads. The feed mechanism again becomes active by reason of this cam riding upon the roller-shoe 56, and the product of string-nails is wound upon the drum or spool 17 by the rotation imparted thereto by the described train of gearing.

Changes within the scope of the appended claims may be made in the form and proportion of some of the parts while their essential features are retained and the spirit of the invention is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Having thus described my invention, what I claim as new is- 1. In a nail-making machine of the class described, a nail-forming mechanism limited to two sets of dies, one of said sets of dies having its members formed to point the nails by a compression action solely on the wire, and the other set of dies having head-forming die- IOC Izo

recesses in their coacting faces and in the faces which opposey the point-compressing dies, combined with means for'intermittentlyand positively reciprocating the set of headforming dies, while they are gripped upon the wire, in a direction contrary to the feeding of the wire and into coperative relation to the set of nail-pointing dies, to upset the Wire at intervals and form the nail-heads, subst-antially as described.

2. In a nail-making machine of the class described, a nail-forming mechanism limited to two sets of dies, one of which occupies a stationary relation to the other and said relativelyv stationary dies formed and driven to point and shape the nails by a compression action solely on the wire, and the other set of dies provided with head-forming die-recesses in the cooperative faces thereof and in the faces which oppose the point-com pressing dies, combined with means for opening and closingeach set of dies intermittently, and means for positively forcing said header-dies, while gripped upon a wire, toward and in coperative relation to, the relatively stationary shaping-dies, whereby two sets of dies operate on a wireto head and point the nails, as set forth.

3.,'In a nail-making machine, the combination of a set of relatively stationary shaping and pointing dies, another set of independent header-dies having gripping-faces and headforming die-recesses, die-actuating means whereby the dies of each set may be forcibly gripped upon the stock, and quickly opened prior-,to advancement of the stock, and means for positively moving the set of header-dies toward the shaping and pointing dies and for lifting said header-dies on the return movement thereof, whereby the header-dies are given ample clearance for the nail-heads, substantially as described.
