Application filed December 17, 1889- Serial n5. 3534,5114. (No model.)

The invention relates to a machine for mak-' ing nails from wire having a rolled point, for transferring the nailsto the nail-driving device to the nail-driving mechanism, and to various details of construction and organiza tion, all of which will. hereinafter be more particularly set forth. I a

In the drawings the invention is illustrated as embodied in a machine for driving nails singly into the solesof boots and shoes.

Referring to the drawings, Figure 1 is a view in side elevation of amaehine having the features of my invention. 2 is a view in vertical section taken through the die-rolls. Fig. 3 is a view inside elevation of the head of the machine enlarged. Fig. 4 is a detail view to illustrate a portion of the mechanism for operating boot or shoe feed, to which reference is hereinafter made- Fig.5 is a de-. tail view in section illustrating the boot. and shoe feedi 6. a V w il ustra ing. a portion of the wire-feed. Fig. 7 is a detail view representing the positionof the parts in the act of driving the nails Fig. 8 is a viewrepresenting the dies as having a point drawing section and also a feeding-section, to which reference will hereinafter be made. Fig. 9 is a view in plan ofa portion ofthe reverse-feed roll. Fig. lO is aview of the same, with the exception that a feed-block for imparting a shorter vertical feed has been substituted for the one represented in Fig. 9; and Fig. 11 isa view in section of a portion of the feed-rolhshowin g the feed-block of Fig. 10 thereon.

A is the standard of the machine. Upon it is mounted the frame a, carrying the nail making and driving devices.

B is the driving-shaft of the machine. It carries the driving-pulley 17, upon which is arranged one section b of a clutch. 'There which enter the'hole in the shaft. 1 lengthwise the shaft 0 is given the cut-off bar bymeans of the slide d upon the shaft O,

is arranged upon the shaft B to engage this membe'rof the clutch the member b which is formed upon or attached to the pinion 12 This pinion, with the member b of the clutch, is given a movement upon the shaft to engage and disengage the section b of the clutch by means of the lever b pivoted at b and connected by the rod 1) with an operatingtreadle b". The upper end of the lever 19 is forked and connected with the pinion b and member of the clutch by pins 12 which ent ter a groove b in a collar attached to the pinion or integral therewith. A spring Z2 attachedto the treadle at one end and to the frame of the machine, serves to lift the treadle andto move the pinion and the member, I) of the clutch from'engagement with the member I) and to hold the said member disengaged.

.. The shaft B is connected with the roll-shaft O by means of the gear 0, and the shaft 0 is connected with the other or second roll-shaft Obya gear 0', which meshes with a gear upon the'shaft C. At the forward end of the shafts C O are the die-rolls D D. Each die-roll carries three sections dd d of three pointingdies. The die-roll D also carries a cut-off d f for each die, operated by an operating-bar d 1 contained. in a central hole in the shaft 0 and having its end wedge-shaped or tapered to act against the inner endsof the cut-off bars Motion connectedwith the bar by means of a pin passing through a slot in the shaft, the lever 'df, pivoted at d and the cam projection d upon the cam disk d at the front end of the shaft B, and the retracting-springd The roll D has a presser-bard for each die forcedoutwardby'a spring. The cam-shaft B makes three revolutions for. everysingle revolution of the die-rolls D D. The .dies are shaped to not only form the point of the nail in the wire, but also to feed the wire a limited distance,the die-surfaces being roughened or corrugated to accomplish this purpose, and in Fig. 8 I represent the dies as thus formed, the sections e of the dies representing the pointing-sections and the sections e the feeding-sections. Of course the pointingsections feed the wire equally with the remaining sections of the dies, but they act additionally to roll the point of the nail in the wire as they feed. If it is desired -to obtain a shorter nail than. is thus pointed and fed from the wire after a pointed section has been contact with the wire to lift or draw back the same any desired-extent, so that upon the coming together ofthe next set of pointingdies they close such distance fromtheendof the previously-pointed wire, as may be desired, which distance is regulated by the width of the feed-blocks f f. These blocks have corrugated surfaces and are adjustably secured to the rolls F F. (See Figs. 9, 10, and 11.) Each of the rolls F F is represented as havg for the reception of the nail. The trans ferrer is at the end of a bar 9 which is bya link g connected with the lower end g of a lever g This lever is pivoted at g and connected at its upper end 9 with the-cylindercam g on the shaft'B. The cam moves the transferrer from a position which brings its hole j 2 in line with the end of'the wire which is 130%6 fed therein and severed to a position over the throat-hole g and under the driven H; (See Fig. 7.) The driver H is secured to a driver-bar'h, carried in a housing h, and the driver and bar are reciprocated at the proper interval of time by the lever k con- .nectedby a link 12 with the upper end of the driver-bar, pivoted at h, and connected bya link h with a slide h having a cam-pin 72. which enters a cam gro'ove 71. in the cam-disk h on the shaft B. Beneath the throat plate g is arranged a stud M, secured to the frame of the machine and having a hole m in coning th'ree'of these blocks. This is because the rolls are rotated at the same speed as the dierolls D D, and the roll F is supported upon a shaftf and the roll F upon the shaftf These shafts have bearings in the-frame of the machine and are connected by'the gears f f respectively, with gears f y upon the shafts O 0, these gears f f connecting the two shafts O 0 together at their forward ends, sai'dshaf'ts O O, as above stated, being connected at their rear ends by the gear 0' on shaft 0 meshing with a corresponding gear on shaft 0, said gears f f also meshingwith the gears f f, and this connection causes, of

course, the feed-block rolls F F to be rotated in the direction opposite to that of the dierolls D D.

The devices for feeding the wire backward are represented in the form of blocks having preferably roughened surfaces and attached opposite to each other to rolls adapted'to be turned backward. These blocks during the forward or usual feed of the wire separate from each other to permit the movement of the wire. They are closed upon the wire and moved backward when the .wire is released by the usual feeding rolls or devices, and the extentof the said backward-or reverse feed feed produced by the dies and usual feeding devices. The feed-block is held to the roll by screws, which permit it to be detachable, and the recesses are of a length to receive the longest feed-block, and thus provide for any lesser length desired.

The hail as it is pointed and severed is delivered from the dies to the transferrer G.

' This is mounted upon a plate 9, having a throat g at'its forward end, andit has ahole tinuatlon of the throat g in the plate 9 and through which the nails are driven. This stud also furnishes a bearing for a feed-roll N and its operating-gear n and also for the free or loose roll 12. The feed-rollN isback of the passage 'm in the stud and has a roughened or corrugated surface. The loose roll 11. is in front of the. said hole 'm. There-is arranged upon the feed-roll N a guidingflange n against which the edge of the boot or shoe sole is held in contact during the nailing operation. This is preferably formed at the front of a sleeve n adjustable length- :wise the feed-roll Nby means of a screwthread connection between the two, andfit is The feed-roll is positively ro-.

I lockedin any desired position by means of a set-screw n rated by means of the gear a uponthe shaft nflwhich meshes with the gear 'n, and the gear 12 and its shaft n are rotated by means of a ratchet-wheel n upon said shaft n, the

. feed-pawl n at the lower end of the .lever n pivoted at n and connected at its upper end by a cam-pin n with a cam-groove n in the cam-disk 71 on the cam-shaft B. The "cam,

of course, imparts the feed movement to the feed-roll immediately after the driving of the nail, but before-another nail is brought into position by the transferrer tobe driven. A detent-pawl n engages the teeth of the verse movement of the feed-pawl n The boot or shoe is represented as'supported ratchet-wheel n and holds it during the re;-

upper end a clenching-cup or, preferably,

- a grooved antifrictionroll 0 (see Fig. 7,.) held in a pocket in the end of the horn and supported not only by its holding-shaft, but by the horn bearing upon its under side. This horn O is pivoted to swing horizontallyat '0 to a bracket 0 extending from the frame A,

and it is attached to a rod 0 having a vertical movement and extending to a lever 0 which is pivoted at o and carries at one end a heavy counterbalance and blow'absorbi'ng metal block 0 and at the other end a treadle end 0 (See Fig. 1.) The wire is fed from a reel P, conveniently located through suitable guides to the drawing-rolls.

The operation of the machine is as follows: The boot or shoe is placed upon the horn and the horn lifted by means of the treadle o to bring the upper surface of the sole in contact with the feed-roll, the sole edge being held in contact with the edge-guide. The operator then starts the machine by depressing the lever b and this causes the dies to roll points in the wire and the cut-offs to be operated to sever the pointed ends and the reverse feed to be operated to vary the length of the nails and the nails to be transferred by the transferrer in successive order and driven from the transferrcr by the driver through the throat into the sole. The machine is so timed that after a pointed nail has been delivered to the transferrer the feeding of the wire ceases while the transferrer moves the nail forward to a position under thedriver. The driver is immediately reciprocated to drive the nail from the transferrer into the sole of the boot or shoe. The transferrer is immediately returned, the feed-rolls caused to feed the shoe any desired distance, and the pointed end of the wire fed into the nail-receiving hole of the transferrer and then severed.

It will be seen that the horn holds the shoe with the sole in contact with the feed-roll also, that where the horn is provided with a roll at its point, as shown in Fig. 7, the sole is held between two rolls, one of which is positively driven and one is not. It will also be seen that the nail is driven between the upper roll, which is positively driven to feed the work and bears on the outside of the stock, and a second roll that is free to rotate and which simply acts as a bearing-roll and not as a feed-roll. It will further be seen that by placing a teat or extension upon the stud in line with the hole therein the boot or shoe may be channel-nailed-that is, the teat would extend into the channel and guide the placing and driving of the nails therein. It will further be seen that by changing the shape of the upper end of the horn the machine can be used for driving slugs into the top lift of a I boot or shoe heel.

Of course it will be understood that the drawing-dies can be modified to produce any desired form of point and that they can be used upon wires of all section, either square, round, or rectangular, and that the reverse feed-blocks ff need not be used if not required, or if it is desired to make short nails or slugs that they may be of any desired width to reverse the feed of the wire. It will be seen that these feed-blocks act when used after the transferrer has received its nail and starts forward and before the next set of dies in order closeupon the wire.

In some instances it will be desirable to make a long nail instead of a short nail, in which case the pull or draw back feed will not be used and the longer nail will be obtained by the employment of dies such as are represented in Fig. 8-that is, dies having point-formin g sections and also a feeding-section.
