SPIKE-MACHINE.

SPECIFICATION forming 'part of Letters Patent No. 272,994, dated February 27, 1883.

Application iled June. G, 1882. (No model.) Patented in Canada August 7, i882, No. 15,244.

To all whom tt may concern I Be it known that I, GEORGE H. VARING, of Indiantown, in the county of St. John,NeW

' Brunswick, in the Dominion of Canada, have invented a new and Improved Machine for Making Spikes, Bolts, Rivets, 85o., of which the following is a full, clear, and exact description. y

Reference is to be had to the accompanying drawings', forming part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure 1 is a plan view of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional elevation taken on the line w a: of Fig. l. Fig. 4 is a detailed sectional view, showing the construction ofthe removable dies and the method of securing them in the diewheel. Fig. 5 shows the form of one of the blanks for railroad-spikes, and Fig. 6 shows the forni of onerailroad-spike completed. Fig. 7 is a central section through the die-wheel,

` showing the manner of opening the jaws of .the crank or eccentric d in its center.`

The sliding headE is placedin suitable ways 'formed in or secured upon the inside of the side plates, A A', and is reciprocated by the shaft D, the same being connected with the crank or eccentric portion el of the shalt by means of the'connecting-rod F. This reciproeating head E carries the bending or heading tool f at its forward end, which bends or forms the blanks inthe removable dies H, held in the die-wheel G. This die-wheel G is formed with the chambers or recesses g g, in which the said removable dies H are placed. There will be several sets of these removable dies, according to the number of different articles desired to be made with the machiue,which dies willbeinterchangeable with each other in the die-wheel. The bolts, spikes, or rivets are shaped and headed in these dies by the said bending orheading tool f, as just mentioned, and the blanks for the same are cut from a heated rod by the knives J J, the rod being fed between them into the dies irom the rear of the machine as the die-wheel revolves. The die-wheel is revolved intermittingly from the shaft D by means of the crank e, secured thereon, ratchet c, secured upon the shaft of the die-wheel, the pawl b, and the conneetiugrod d', which ebunects the pawl with the said crank c, as shown in Fig. l. The ratchet c has as many notches as there are dies in the die-wheel, land they are so arranged that each movement of the wheel will bring one of the dies on a line with the heading or bending tool f and cutting-otf knives J J. i

Each of the dies H is formed of the chamvbered. block h and the jaw h', hinged therein,

as shown in Fig. 4. The cavity p between the face'of the jaw and the walls of the chambered block may have the form and size ofthe bolt, spike, rivet, or other article to be made.

In Fig. 4 a die for making railroad-spikes is illustrated. 1n this .form of die the cavity is made pointed for shaping the point end of the spike. The chambered block is formed with projections or lips at its back edges to lit in under-cuts or grooves formed in the recesses g g of the die-wheel, as shown in Fig. l, for hold- *ing the die from outward or sidewise movement, and on the back of thejaw h is formed the inclined lugf, which runs in contact with the cam-plate M, secured in proper position to the inside of the frame-plate A as shown in Figs. land 7, for opening the jaw for discharging the complete bolt, spike, or rivet.

For preventing the die from moving radially out of the recesses in the die-wheel, I employ the I -shaped key y, which is slipped in the recess back of the die, and held in place by the screw y', the lip ofthe key resting upon the edge ot the block le, as shown in Fig. 4.

K is a sliding head-block, having a diagonal face, which closes the jaw h' of' each ofthe dies upon the blanks in the die just at the time the dies are brought successively in line with the tool f, thus holding the blanks as in a vise while the head is being bent or formed by the tool. This head-block K is held parallel with an d which passes back th rough the reci procating head E, and this rod and head-block are reciprocated for closing and releasing the said jaws It' of the dies by the cam N, fixed upon the shaft D, the rod and cam being connected together for action by means of the divided yoke L', placed upon the small rod or shaft 1J', as shown in Fig. 3, upon which it rocks as the cam revolves. rlhe member q of the yoke is provided with the friction-rollers s s', the former running in contact with the cam, the latter being surrounded by the loop t, formed at the rear end of the rod b'. This loop accommodates the rocking movement of the yoke L', and causes the cam to impart to the rod b' and head-block K only` a straight reciprocating motion. The member q' of the yoke is provided with the friction-roller t', which runs in contact with the cam, as shown in Figs. l and 3.

For causing the dies in the die-wheel to come exactly in line with the tool j' at the time the head E is moved forward for heading or bendingthe blank, I provide the machine with the reciprocating wedge-shaped head K', which is moved forward slightly in. advance of the tool j', and enters at each operation of the machine one of the claw-plates S, secured upon one side ofthe die-wheel G, as shown in Figs. 1 and 2. There are as many of these claw-plates as there are dies in the wheel, and they are made adjust able upon the wheel by means of the slots u and screw-bolts a', and the said wedgeshaped head is held parallel, or nearly so, with the tool f and head-block K by means ofthe rod ct', to

is formed with the loop w, Fig. 1, which joins the rod ct' to the yoke in the same manner that the rod b' is joined to the yoke L', as above described, and as shown in Fig. 3, which arrangement causes the cam N' to impart to the rod and wedge shaped head only a straight reciprocating motion.

The knife J' is a stationary one, having a tang, 0"', threaded at its end, held in the inclined slot in the housing plate j, between the shoulder o on` the tang and the nut o', so that the knife may be raised or lowered or turned axially for cutting the blanks square across from the rod, or at a greater or less angle, according to whether the bolt, spike, or rivet is to be made pointed or not.

The knife J is adjustable upon its rod j' by means ofthe set-screw jz, (see Fig. 1,) passing partly through the knife J and bearing against the rod j', so that its edge may be brought to correspond with the position ofthe edge of the knife J'. This knife is reciprocated once for every movement of the die-wheel for severing' the blanks from the rod of iron being fed between the knives and into the dies, by means of the crank-shaft L, which is rocked by means of the cam l, formed on the large cog-wheel C, coming in contact with the arm k, formed on the rear end of said shaft. 7c' is the crank at the other end of the shaft, to which the rod j', carrying the knife J, is attached, and Z.' is a weight attached to the arm m of the shaft L for returning the shaft and knife to their normal positions after cutting each blank.

If railroad-spikes are to be made by the machine, the knives J J' are to be set at an angle, as shown in Figs. l and 3, so that the blanks will not be cut square across from the rod, but will be made pointedas shown at a in Fig. 5. When the spike is completed it will have the form shown at n' in Fig. 6. Vith this form of blank it will be seen that the rst effect of the bending or heading tool, when brought against it in the die, will be to shape the point of the blank-that is, to simply bend the point already formed to the center of the blank, and then to bend over the outer end of the blank to form the head of the spike. Both ends of the blank being already pointed, the amount of power required to give this form to the blank is comparatively small.

The tool f is made adjustable in the reciprocating head E by means of the screw f", and there will be various forms of tools, according to the articles desired to be made upon the machine.

For keeping the dies and the die-wheel cool and always in good working condition, I provide the machine with the water-trough Q, which is kept filled with water, into which the lower edge of the wheel is submerged, as shown in Fig. 3.

The cavity in the dies for making bolts or rivets will not be made pointed at the bottom, but will be made with a dat bottom, and the knives J J' will be adjusted so as to cut the blanks square across from the rod, and the blanks will not be bent, as in the case of railroad-spikes, but will be simply upset to form the head.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a spike-machine, the intermittingly-re- Volving die-wheel G, provided with the adjustable claw-plates S, having slots u and bolts u', in combination with reciprocating wedge- IOO IIO

shaped head K', substantially as and for the erwin i s ing threaded tang o"', shoulder o, and nut o', and adjustable reciprocating cutter J, substantially as shown and described, whereby the blanks may be cut square or diagonal, as set forth.

4. The gear-Wheel C, formed or provided` with the cam l, in combination with the shaft L, formed with the cranks lc and lc', the rod j', and the knives J and J', substantially as described.

5. The die-Wheel. formedwifh recesses, in combination with the removable dies H and the keys y and screws y', for holding the dies in the recesses of the die-wheel, as set forth.

6. In a spike-making machine, the eccentric 15 shaft D, provided with the cams N and N', in combination with the sliding head E, reciprocat-inghead-block K, reciprocating wedgeshaped head K', and intermittingly-revolving die-wheel G, provided with the plates S, and 2o adapted to carry the dies H, formed with the hinged jaw h', substantially as described.
