rr snares arena? rro SOLOMON M. CUTTER, OF READING, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGN- MEN'IS, TO UNITED SHOE MACHINERY COMPANY, A CORPORATION OF NEW JERSEY.
Specification of Letters Patent.
Patented June 1910.
Application filed April 19, 1898. Serial No. 678,149.
To all whom it may concern:
Be it known that I, SOLOMON M. CUTTER, of Reading, county of Middlesex, State of Massachusetts, have invented an Improvement in Wire-FeedingIvlechanisms for Nailing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This my invention relates to mechanism in nailing machines whereby a continuous wire is fed and nails severed from the wire and carried into position to be driven into stock.
Other features of my invention consist of the simple means whereby the wire-feeding mechanism is operated, and of the combination of parts connected with the wire-feeding, and combined nail-carrying and wirecutting mechanism.
In the accompanying drawings: Figure 1 is a front view of the upper part of a machine embodying my invention. Fig. 2, is also, a front view of the same machine, but for more clearness the front plates, covering part of the mechanism, are removed. Fig. 3 is a side view of an adjustable stop, whereby the extent of the feeding of the wire is determined. Fig. 4 is a top view of the wire-feeding mechanism, Fig. 5 is a sectional view of the wire-feeding mechanism.
The same letters of reference indicate similar parts in all the figures in the drawings.
The driving shaft a carries a cam a which is provided with a crank-pin a and with a cam-groove 7), shown in dotted lines, and has the width of its periphery divided into two independent parts I) and b. The part b operates a lever cl, which is fulcrumed to the frame 0 at c and has a projection adapted to engage the awl-carrying bar 0 and move the latter toward the driver d after the awl e is moved into the stock, and thereby forcing the awl to feed the stock. A spring d is attached to the awl-carrying bar and to the frame, and the tendency of this spring is to move the awl-carrying bar from the driver and thereby, also, tending to hold the lever 12 in contact with the cam a. The awl-carrying bar 0 carries the awl e in a well known manner, and is loosely attached to the free end of a lever c, which is hung on a stud e and provided with a cam-roller f engaged by the camgroove 6, and thereby the free end of the lever is moved up and down and forces the awl to puncture the stock. Another lever f is fulcrumed to the frame at f" and is periodically operated by the operating part b of the cam, for the purpose as hereinafter set forth, and which lever is held in contact with the cam by a spring 9. The:
driver cl is carried in a block or driver bar g which is given a reciprocating motion by the connection bar 9, which is hung on the crank-pin a.
These mechanisms, so far as described, are the same as in the Letters Patent No. 582,57 9, issued to me May 11, 1897, in nailing machines adapted to drive nails severed from a comb-shaped strip.
The wire j used in this machine can be carried on a reel, or by any other suitable means, and is shown extended through a hole in a block h, the hole being shaped to present a shoulder to sustain one side of the wire. This hole contains a spring-pressed pawl or pawls h to grip and hold the side of the wlre opposite that sustained by the shoulder of said block as the latter is being moved downwardly to feed the wire, the pawls sliding over the wire as the block is moved upwardly. A spring-pressed pawl h shown in dotted lines Fig. 2 is pivoted to a stationary part of the machine and arranged to engage the wire below the block it to prevent the wire from being moved back wardly by the upward movement of said block. The block 72, is loosely sustained and may be reciprocated in a groove 1) formed in the frame 0, the block being retained loosely in said groove by a cover plate 71. An arm 2' is extended from the block it into the pathway of the driver carrier g, and said block is moved upwardly thereby as the driver carrier and driver are elevated. The block 72, is moved downwardly normally by a spring j connected at one end with a stud j" extended from said block through a slot in the cover plate i, the lower end of said spring being connected with a suitable stud on the cover plate. The block in its descent through the action of the spring is arrested by an adjustable stop 7" attached to the plate i by means of a screw H, see Fig. 1, said stop being slotted at n for the reception of said screw. By adjusting this stop the extent of the downward movement of the block may be regulated to correspond reciprocated a nail carrier m through a lever f, the lower end of which engages said nail carrier. While the nail carrier -remains in its outer position from the driver,
a perforation m of said carrier shown in dotted lines Fig. 2 is in line with the perforation 7c and the wire feeding mechanism is timed to feed the wire through the perforation k and into the perforation m.- After the wire is fed into the perforationv nail will be severed from the wire, and as ,m the nail-carrier is moved toward thedriver, and .it' will .be readily seen that -.a,
the nail-carrier is .continued in its move ment the severed nail is carried forwardin .the perforation m until it is in line wlth the driver, where it remains while the driver enters the perforation or nail guide m and drives the nail into a the awl in the stock.
perforation left by} f rier having a hole .to receive the end of the Having thus described my invention, what f I claim is:
fastening inserting mechanism, fastening separate means comprising an element of said fastening inserting mechanism for posiv tively restoring said block to its initial position.
2. A machine of the class described, having in combination, fastening inserting mechanism, fastening forming mechanism, and means for feeding w re to said last named mechanism comprising a block car-l r in wire-en a in awls arran ed to engage the wire at successive points, a guide for said block, yielding means acting normally to move said block in the direction to feed the wire to said fastening forming mechanism, an adjustable stop for determining the amount of feeding movement of said block and separate means comprising an element ofsaid fastening inserting mechanism for positively restoring said block to its initial position.
3'. A machine of the class described, having combination, reciprocating fastening inserting mechanism, fastening forming mechanism and means for feeding wire to said last-named mechanism comprising a block provided with a wire-guiding opening, a plurality of spring-pressed pawls arranged to engage the wire in said opening at a plurality of successive points and to lockit against one side of said opening, when said block is moving in the wire feed ing direction, yielding .means acting normally to move said block in said wire feeding direction, adjustable means for determining the amount of wire feeding movement of said block and independent means comprising an element of said inserting mechanism for restoring said block to its initial position.
