MACHINE FOR BARBING wiRE NAILS.
SPECIFICATION forming part of Letters Patent No. 424,227, dated March 25, 1890. i Application filed October 4, 1889. $erial No. 325,976. (No model.)
-.l'0 all whom it may concern:
Be it known that I, JOHN M. SCHILTZ, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use-' nail; next, of means of adjustment, and,
finally, of details of construction and arrangement, as will be more fully hereinafter set forth.
Figure 1- represents a plan view, partly in section, of a nail-making machine embodying my invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a top plan view of a portion of the frame and my improved barbing attachment. Fig. 4 represents a side elevation, partly in section, of
said attachment. Fig. 5 represents a section on the line so cc, Fig. 3. Fig. 6 represents a detail plan view of the barbing-plates, showing one of the same turned in position for sharpening. line y y, Fig. 6.
Fig. 7 represents a section on,
1 of two sliding knives or cutters 0, which are Similar letters and numerals of reference indicate corresponding parts in the several:
figures.
Referring to the drawings, A designates the stand or frame of a nail-making machine, on which rests the bed B, having thereon the rollers 0, between which the wire D is fed to the machine by said rollers 0 giving tension to said wire.
E designates a sliding plate having suitable guideways attached to the bed B. The side portion a of the said plate, which has a downwardly projectin g flange parallel to and sliding against the side of the bed 13, is suitably connected by a rod F to a yoke working on an eccentric G. The eccentric G consists of a hollow cylinder having a flanged portion 1), by which it is attached eccentrioally to the wheel l-l, revolving on shaft J.
On the slide E is a clamping device, consisting of the stationary jaw 0, having an angular attachment d on its inner side, and the movable jaw 6, having a pin or stud f proj ecting therefrom toward the said angular at tachment d, the said pin and attachment being kept in proximity by means of a spring g.
K designates a holding device, consisting of a stationary jaw 7t and a movable one j,
both of the said jaws having projections corresponding to the serrations desired on the nail. The movable jaw j is actuated or controlled by an attachment or adjustable arm L of the lever M. One end of the said lever M is pivoted, as at 75, while the other end limit thethrow of the lever M and preventits bearing against the cam N during a portion of the revolution of the said cam. The pressure upon the cam N by the lever M is also sustained by the block m, securely attached to the frame and in contact with the friction-rollers m, thus releasing the other parts from a lateral strain caused by the said pressure of the lever M upon the cam N.
O designates the cutting device, consisting secured to adjustable arms 13 of the pivoted levers P, and are so shaped as to forma point or sharpened end to the piece cut from the wire, the arms 19 being adjustable by means of screws p, working in'openings in the ends of the said levers P. The said levers P ride upon cams Q, secured to shaft J.
R designates a hammer, and q a wiper attached to the shaft J, for drawing back the said hammer after a blow has been given to the wire.
S designates a lever having arms pivotally secured on shaft r, provided with suitable bearings. The short arms 5 of the lever S ride upon collars or flanges on the shaft J, each of the said collars or flanges having on its periphery a projection :5. Attached to the long arm of the said lever S is a cutting or trimming device projecting downward toward the wire. A spring y, secured to a boss on the bed B,kceps the short arms sof the lever. S in contact with the collars or flanges on the shaft J and the long arm carrying the trimming device above and away from the wire until the projections t lift the short arms, forcing down the said trimming device.
Between the end a of the hammer R and the tail-block v a wooden spring U is placed, the said spring being formed of two strips of wood it), having between the lower ends a wedge-shaped block 00, which strips and block are fastened together by a bolt passing through them, as shown in Fig. 2, or may be otherwise properly secured.
On a block 1, secured to the table B,-ahead of the holder K, is mounted a barbing attachment 2, consisting of a stationary plate '3 and a sliding one 4. The said sliding plate 45 is formed With'a dovetail flange 5, fitting in a corresponding groove 6 in said block 1. The
' block 1 is adj ustably fitted in the table B, and
may be longitudinally moved, when desired, by screw an, in order to accommodate barbin g of diiferent lengths of nails.
To the inner end of sliding plate 4: is removably secured a part of the bZtIb-OLlhtBIS C-OII- sisting of a set of plates 7, pivot-ally connected I to permit lateral movement thereof for the purpose of sharpening the cutting-edges 8,? formed in said cutters 7. The stationary plate 3 supports a similar set of barb-cutters 1 9, which coact with said cutters 7, as shown in Figs. 6 and 7, said cutters 9 being adjustthe same in place.

plate is slid inward or toward the body of the machine, the wire is guided into the barbcutters 7 and 9, which are apart when the wire i-sbrought forward by the feeding mechan-;
ism, and said wire is then guided or advanced to and through the holder K, the jaws of which are also apart. Vthen the wire has been forwarded the desired length, which may be regulated by adjusting the eccentric G on the wheel H, the jaw j, actuated by the cam N, closes thereon, and the end thereof is struck by the hammer R, actuated by the wooden spring U, thus forming the head of the nail. A further rotation of the shaft J forces back the hammer R by means of the wiper g on the said shaft and causes the plate E to slide outward, and the barb-cutter 7 is forced inward on the wire which lies against cutter 9 by means of the arm 12 of lever W, the latter being actuated by cam X, to thereby form' the barbs. The clamping device, owing to its form, is released from the wire,
and when the plate E, having reached its outer.
limit, returns, the wire, being released by the holder K and gripped by the clamping device on the plate E, is forwarded or advanced another length. The cams Qnow actuate the levers P, bringing together the cutters or thereon, when it is immediately raised by the 1 able by means of a screw 10. Cap-plates 11 are secured over said cutters 7 and 9 to hold The sliding plate i of said barbing attachment is actuated orcontrolled by an adjustable arm 12 of a lever WV. One i end of the said lever W is pivoted, as at W, while the other end rides upon a cam X, rigaction of the spring 1 The hammer R is now released from the control of the wiper q, and, being forced by the spring U, strikes upon the end of the wire, thus forming a head thereon. The cutters 0 and the trimming device on the lever S are operated by the cam-connections at each revolution of the shaft J.
; The wire is then-forwarded, as before de- To vary the stroke of the lever W an adj usting-screw 13 passes therethrough and 1 bears against a head-block 14, secured to plate. 3 4, and to sustain a proportionate adjustment the arm 12 is provided with an adjusting scribed, and a length according to the adj ustment of the eccentric G is cut therefrom, the end of the remaining part being first trimmed and then headed, the operation described be ing as desired. I
Having thus described my invention, what I claim as new, and desire to secure by Letters stationary barb-cutter 9-, a stripper 16 is pivotally secured to the support of the sliding barb-cutter, said stripper comprising a pivoted arm 17, having an opening 18, through 1 which the wire is fed to the barb-cutters.
