' IMPROVEMENT IN NAIL-CUTTING- MACHINES.

The Schedule referred to in these Letters Patent and making parl:` of the same.

To all whom "it may concern l'e it known that I, MATTHEW JAMES RICE, of Bir- Figure 1 is a vertical longitudinal section of mymachine. v

-the whole of the apparatus attached to itfoscillates upon a bearing or centre, c, formed in the stationary ame c, which supports the machinery.

c2 c2 are adjustable blocks in the frame c, upon which` the frame a oscillates.

d is'the stationary feed-table, attached to the sta'- tionary supports di di, which are capable `of adjustment in a vertical direction, so as to regulate the angle at which the plate of metal to be cut (hereinafter called the nail-plate) is. fed into the machine.

The oscillation of the' frame a and parts attached causes the cutters to assume different angles to the feed-table, so that they will cut the nail-plate, first at one angle, and then at the other, leaving a sufficient portion of the thicker end of each blank projecting beyond the gripers for the heading-tool'to act upon, first on one side of the machine, and then on the other.

e is the stationary cutting-tool, secured, by means of the set-screws e, to the frame a.

f is the moving cutting-tool, secured, by means of the set-screws f1, inthe vibrating frame f2, to which otion is communicated by a crank upon the axis b, by means of the connecting-rod f3.

The axes of the vibrating frame fZ are supported by the bearings a upon the frame a..

g is a gauge, of the' ordinary form, Working in a recess at the back of the cutting-tool f, and the gauge g is suspended at gl 'from the frame f l, so as to be capable of movement.

Before the cutting-tool f descends to cut olf a blank, the end of the nail-plate is -pressed against the part of the gauge g which is below the cutting-tool f, so as to lovercome the resistance of the spring g2, and bring the gauge g in contact with the set-screw f, in the. vibrating frame f2,- andby turning the set-screw f, the amount of metal cut oli for each nail is regulated.

After the blank is cut oif, it is carried down the face of the fixed. cutting-tool e by the cutting-tool uthe spring q2 acting to cause the gauge g tohold the-' blank against the face of the fixed cutting-tool e during -its descent.`

f5 is a-set-screw, which acts as a stop to regulate the position of the gauge g in relation to the cuttingtool f.

h is a nipper, secured in the frame a, and when'the nail-blank is brought into a suitable position, the moving nipper L is caused to press against the nail-blank, and hold it until the griping-tools come into operation.

The gauge g is forked at the end, so as to allow of the nipper fi to pass through it, and act as above de scribed.

The nipper t' is actuated in the following manner:

i2 is a cam upon'tle axis la, and the cam 'iz acts upon i the lever i3, moving upon the pin i", carried by the bracket i5, secured to the frame a.

A'lhe nipper t' is connected by a pin-joint to the lever is, Aand moves in a recess formed in the slide j.

The nipper i is'withdrawn from the nipper h, when allowed by the surface'of the cam i2, by means of a spring, t6, attached to the bracket i5, and pressing p against the ilever t3.

- k k are griping-tools, h elow the cutting-tool e, secured in the frame-Qt by means of the set-screws kf,- and' l l* are the moving griping-tools, secured inthe slide j by means of the set-screws Z2.

The slide j moves in' a groove, formed in the frame a, and after the nail-blank is brought into a proper position, by the means above described, the gripingtoolsl Zl are brought to bear according as the heading is to take place at either side of themachine, and hold the blank during the heading-operation in the following manner: A p

j3 is a cam on the axis b, which acts upon the lever j, moving upon the pin ji, secured to the ame a, and the leverj4 presses against the end of the slide j, soias to bringv the griping-tools into operation, Jwhen required. v

j is a spring, attached to the slide j and bracket t5, and this spring acts to withdraw the slide j and gripers Z l1, after the heading of the nail.

'The slide j and lever j* may, if desired, be secured l by a link, to insure the withdrawal of the slide j, in case of accident to the spring ji. Y

When the blank is securely held between the grip-- ing-tools, the heading-tools m and n are brought into operation upon the end of the nai1blank,'projecting beyond the griping-tools.

The heading-tools m and n, though they are moved up to the griper at each action of the machine, operate alternately to form the head of a nail, according to the angle of the machine when the blank wascut oli'.

The heading-tools Am and n aresecured in the slides m and n by means of the screws on. and ai, and the slides m" n' are supported and guided upon the frame c, at the points a a3.

The heading-tools m and n are actuated in the following manner: j

tIn is a ily-wheel, and 'n3 a toothed Wheel, secured upon the axis b, and the fly-wheel ma and toothed wheel'w" carry crank-pins, which'communicate motion to the levers m4 w, by means of the connecting-rods m5 a5. i l

The levers m umoveon pins, secured in the brackets mi n, fixed to the frame a.

m7 a7 are stirrups or connecting-links, by which the movement of the levers m4 n is communicated to the knuckle-joints ons a8, having their fulcra upon the projections a. a?, upon the frame a, and the point-s m9 n.9,

upon the slides ml nl.

fm um are pins, xed to the 'ame a., and acting upon the slides m1 a, so as to withdraw them and the heading-tools, after operating to form the head of the nail.

The axis b is of conical form at either end, and the y-wheel m3 and the toothed wheel n3 are secured upon the axis b by means ofthe nuts b b2, so that when. the crank-pins' are adjusted to the required position, by tightening the nuts b b2, the fly-wheel on. and toothed wheel 'n3 can be secured upon the axis b.

When the nail is finished, and the griping and heading-tools withdrawn, the nail is allowed to fall througlrthe opening 11, in the frame a, into a receiver placed below the machine.

The''rame c and parts attached are caused to oscillate from side to side, s o as to cnt' the nailplate, first at one angle, and then at the other, in the following manner:l

o is a toothed wheel, driven by the toothed Wheel as, upon the axis b.

The toothed wheel o moves upon the stud o, secured to the frame a, and carries a crank-pin, the throw of which is capable of adjustment.

c3 is a bracket upon the stationary frame' c, and o2 is a connecting-rod, connected, by means of ball-joints, to the bracket c" and the crank-pin upon the wheel o,

which, by its revolution, acting against the stationary bracket ci, causes the frame a and parts attached to oscillate.

The nail-plate, upon the feed-table cl, is urged forward against the gauge g, as above described, by means of the sliding piece da, to which the weight cl4 is attached, by means of a cord passing over the pulleys d d; and when the peg (L7 is removed, and the piece-da released, it is at once pulled by the Weight to the lower `end ofthe table d.

The nail'plate is inserted inthe removable tongs d8, and with the tongs is placed on the table d, the tongs and nail-plate being supported upon and guided by ledges on either side of the table d.

The peg d is then removed, and the piece d3 allowed to press against the hinder end of the tongs d8, so as tourge the nail-plate forward, as above described, the tongs being so formed as to be capable of a partial rotation within their support, so as to allow the nailplate to accommodate itself to the surface of the cutting-tool.

The part of the feed-table d" which is above the cutting-tool c, the nipper li., and the gripers k k1, is capable of being 'turned back upon the hinge-j oints d, so as to afford ready access to the working-parts of the machine, without disturbing the position of the feedtable; and when the machine is in operation, the part d is secured, by means ofthe nuts d, upon bolts `carried upon brackets d.

d'3 (Z are brackets, with adjustable set-screws, the ends of which act alternately, according to the angle of the machine, upon sliding pins on either side of the part (Z9, rand the ends of the sliding pins come `in contact with spring-pieces el, on either side of the part d, so as to cause them to guide the edge of the nailplate correctly. i

Having thus described my invention, I would have it understood that I do not confine myself to the exact details, or to the particular form or arrangement of the parts herein described; but

1. The construction and arrangement, upon the vi-r brating frame, of the sliding holders m* n, toggle-joints m5 as, and levers m n", all operating together to give a rectilinear motion to the heading-dies, in themanner described.

2. The arrangement of mechanism, shown and de scribed, for moving the gripers against the blank in a horizontal plane, as and for the purpose specified.

3. The improved nailplate feeder, herein described,

consisting of the jointed tables d ds, and the parts thereto attached, all constructed and operating together, as set forth.
