SPIKE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,052, dated March 1, 1898. Application filed July 7, 1897. Serial No. 643,749. (No model.)

To all whom it may concern:

Be it known that I, LEWIS WILLIAMS, a citizen of the United States, and a resident of Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Spike Machinery, of which the following is a specification.

My invention relates to new and useful improvements in automatic machinery for manufacturing railroad-spikes, and particularly to that class of spikes shown and described in Letters Patent to J. A. Markoe, No. 550,795, of December 3, 1895.

It is the object of my invention to construct a machine for producing railroad-spikes .of special design from a bar of heated steel by a series of operations, as will later be more fully described, and, further, to construct said machine in the simplest manner possible consistent with good work, durability, and ease of operation.

With the above objects in view I have devised the simple and novel construction shown in the accompanying drawings, forming a part of this specification, and upon which similar characters of reference denote like or correspondin g parts throughout the several figures, and of which Figure 1 is a plan view of my machine complete, excepting that the spike-tong mechanism is removed. Said machine is shown in the acts of heading, grooving, and pointing spikeblanks. Figs. 1, 1, 1, 1, and 1 illustrate the five operations of my machine necessary to produce a completed spike. Fig. 2 is a rear elevation of my machine as seen from arrow as of Fig. 1. Fig. 3 is an enlarged cross-section on line 3 3 of Fig. 1 and illustrates the spike-heading mechanism together with the gage for determining the length of stock to be used for each spike. Fig. 4 isan enlarged cross-section on line 4 4 of Fig. 1 and illustrates the construction of the gripping-dies together with the spike-bending arm. Fig. 5 is an enlarged end view as seen from arrow 5 of Fig. 1 and illustrates the mechanism for operating the spike-bending arm 23. Fig. 6 is a detail view of the spike-bending arm 23 shown in the preceding figures. Fig. '7 is a detail cross-section on line 7 of Fig. 6. Fig. 8

is an enlarged detail plan view of the cutting, bending, and heading mechanism shown in Fig. 1, but in its opposite extreme position. Fig. 9 is a detached front elevation of the spike-tongs and mechanism for operating the same, said tongs being in a raised position. Fig. 10 is a cross-section on line 10 10 of Fig. 9. Fig. 11 is a detail end view (see arrow 11, Fig. 9) of the arm and shafts for supporting and operating the spike-tongs. Fig. 12 is a front elevation of the spike-ton gs mechanism shown in Fig. 9, said parts being in their -reversed lowered position. Fig. v13 is a detail vertical cross-section taken on line 13 13 of Fig. 12, the position of parts corresponding therewith. Fig. 14 is an enlarged cross-section taken'on line 1 L let of Fig. 1 and illustrates the connection for operating the gripping-jaws and the rotary table. Fig. 15 is a detail plan view of the rotary table B, which carries dies for retaining the spikes during their grooving and pointing operations, said dies being in a clamped position. Fig. 16 is a sectional plan view taken on line 16 of Fig. 14 and illustrates my novel form of pawl-and-ratchet mechanism for' operating the table B aforesaid. Fig.

17 is an inverted sectional plan View taken on line 17 of Fig. 14, the parts being in their opposite extreme position. Fig. 18 is a front elevation of the holders employed upon the table aforesaid. Fig. 19 is an enlarged detail plan view of the mechanism shown in Fig. 1 for grooving the spike. Fig. 20 is a similar detail plan of the grooving mechanism, the same being in its opposite extreme position from that shown in Fig. 19. Fig. 21 is a front elevation of the spike-grooving mechanism shown in Fig. 19. Fig. 22 is a central vertical longitudinal section taken on line 22 of Fig. 19. Fig. 23 is an enlarged side elevation of the spike-pointing mechanism shown in Fig. 1. Fig. 24 is a vertical longitudinal section of the pointing mechanism shown in Fig. 23. Fig. 25 is a front end elevation of the pointing mechanism shown in Fig. 23.-

enlarged side elevation of one of the pointing-hammers shown in the preceding figures.

As before stated, my machine is entirely automatic in all its movements and completes a spike in five operations upon the stock, as illustrated in Figs. 1 to 1, inclusive. Said operations are performed simultaneously with every complete rotation of the main drivingshaft and complete one spike with each series of operations.

Referring to the characters of reference marked upon the drawings, 1 indicates the bed, which is mounted upon suitable legs. (Shown broken away in Fig. 2.)

2 indicates a driving-shaft which is journaled in boxes 3, secured to the bed, and which bears a driving-pulley 4. From the above shaft all the connections are made for operating the various parts of the machine with but one eXception-namely, that of the pointing mechanism shown on Sheets 1 and 11, which mechanism is preferably connected and operated by a separate belt from an independent counter-shaft.

A represents the stock, (see Fig. 1,) which may be continuously fed to the machine from a long furnace by any ordinary feed mechanism, (not shown,) or it may be heated in convenient lengths and fed to the machine by an attendant. As will be seen, the stock passes through a stationary die 5, contained in the raised part 6 of the bed, and is fed against a movable stop 7, which determines the length of the stock required for a single spike. After the stock has been fed in, as above specified, the first operation thereon is to cut a blank therefrom, which cutting is done by mechanism shown in Figs. 1, 4, and 8 and which I will now describe.

The raised part 6 of the bed is provided with a suitable way 8, in which is fitted a slide 9, carrying cutting and clamping die 10, the latter being held firmly in position by means of the clamping-plate 11. (See Fig. 4.) The slide 9 is actuated from a cam 12 upon the main driving-shaft 2 through toggle connection 13, link 14, and supporting-lever 15, (see Fig. 14,) said link being provided upon one end with a roller to engage a groove of the cam aforesaid, while the opposite end is directly connected with the toggle before mentioned.

From the foregoing costruction it will be apparent that with each complete rotation of the driving-shaft the cam 12 thereon will throw the link 14 to and fro, thus opening and closing the toggle in a manner to operate the slide forward and backward. Said forward movement will cut a blank from the main stock and carry the same slightly to the left, as seen in Fig. 1, where it is held against the stationar die 16,said die being practically a counterpar of the movable die carried by the slide and is clamped to the portion 6 of the bed by means of a clamping-plate 17,as shown.

The blank is held between the dies aforesaid during the heading operation,as is clearly shown in Figs. 1, 3, and 5, the forward end projecting slightly upon the inside in a manner to be operated upon, as will next be described. The first operation upon the blank while in the above position is to bend the free end over, as shown in Fig. 1". This operation is performed by mechanism shown in Figs. 1, 4, 5, and 6, which consists of a rock-shaft 18, j ournaled in suitable boxes 19, bearing an arm 20, the free end of which is provided with a roller to engage a groove 21 in the periphery of the cam 22, secured upon the main shaft. The opposite end of the rock-shaft 18 is provided with a bending-arm 23, having a removable hardened head 24 fitted in the outer end thereof, as is clearly shown in. Figs. 6 and 7. The purpose of said head is to engage the free end of the blank and turn it over at an angle of about sixty degrees, or substantially as shown in Fig. I Said operation is performed and the arm 23 returned to its normal position with each complete rotation of the main driving-shaft.

After the end of the blank has been turned over, as shown, the heading operation takes place and is performed by the following mechanism, (see Figs. 1, 3, and 8:) The bed 1 is provided with ways 25, in which is fitted the slide 26, actuated through link 27 by a crank 28 upon the main driving-shaft. The slide 26 is provided with a detachable block 29, which is clamped therein by means of screwbolts 30 and serves to retain the heading-die 31 in its proper position. The forward end of said heading-die, together with the face of the dies 10 and 16, are suitably recessed to receive the surplus stock of the end of the blank and by reason of the pressure brought to bear forms the same into the desired shape or head, said operation being completed with one rotation of the main shaft.

The stop 7, which serves to limit the forward movement of the stock A, is a movable affair and is raised and lowered with each forward-and-backward movement of the slide 26 in accordance with the following mechanism: Upon one of the ways 25 is secured a bracket 32, to which is pivoted a swinging arm 33, carrying a roller 34, which latter projects inward and is engaged by an inclined fork 35, secured to the slide 26 aforesaid in a manner to engage the roll 34 when the slide is in its forward position and to disengage the same when in its retracted position. Upon the forward end of the arm 33 is secured an adjustable block 36, to which the stop 7 before mentioned is pivoted. The upperend of this stop is connected by means of a link 37 with an adjustable screw 38, secured in a bracket 39. By the above construction it will be obvious that different lengths of blanks can be secured by adjusting the block 36 and the screw 38, which parts control the raised and lowered positions of the stop 7. After the blank has been headed the spike is removed from the dies 10 and 16 and placed in one of a series of five holders mounted upon an intermittently-rotary table, ('

shownon Sheets

1 and 8,) the construction of which willlater be'de-- scribed. The mechanism for removing a spike from the dies as above is fully illustrated on

Sheets

5 and 6, together with Figs. 1 and 2, and will next be described.

Upon the bed-1 of the machine (see Figs. 1 and 2) is provided a suitablepedestal 40, which supports the spike-removing mechanism referred to and is made of a shape to most conveniently accommodate said mechanism. Upon said pedestal is provided boxes 41, in which is journaled a shaft 42, preferably at an angle of about thirty degrees with respect to the main bed of the machine. Said shaft bears a gear 43, which meshes with and is driven by a gear 44 upon an intermediate shaft 45, mounted in bearings '46, Fig. 2, secured to the bed and operated from the main driving shaft through bevel-gears 47, as shown. The connection between the main drivingshaft 2 and the shaft 42 is such that the latter is driven at the same rate of speed, thus insuring this part of the machine working in unison with the other. 40 is further provided with bearings 48 for the purpose of slidably supporting a hollow shaft 49. Upon said hollow shaft is securely keyed a grooved collar 50, which latter is engaged (see Fig. 13) by pins 51 of a forked arm 52, pivoted to the frame at 53 and bearing a roller upon its opposite end, which engages the groove 54 in cam 55 upon the shaft 42. From the above it will be seen that with each rotation of the shaft 42 the hollow shaft 49 is subjected to a slight raised and lowered movement in addition to a rocking motion,

'which will later be described. Within the hollow shaft is journaled a solid shaft 56, and to the upper end thereof is secured a small pinion 57, engaged and actuated by a segment 58, carried upon a bell-crank lever 59, pivoted to a bracket of the main frame. The operated end of the bell-crank lever (see Fig. 10) is provided with a roller to engage a groove in the face of cam 61 upon the shaft 42 and serves as the operative connection therefor.

It will be seen from the above construction that with each rotation of the cam 61 the bell-crank lever carrying the segment is operated in a manner to turn the pinion 57 and its shaft approximately three-quarters of a rotation. The throw of the cam, however, is such as to divide said turn into substantially two distinct movements, the primary one of which is about one-quarter of a turn and the second the remainder or onehalf of a turn. The first of said movements serves to clamp the spike and the second to throw the tongs from one side to the other of its shaft.

Upon the hollow shaft 49 is clamped a rigid arm 62, the extreme end of which forms one member of a pair of tongs of which the operative member 63 is pivoted at 64 and is provided with a link 65, which is connected to a short arm 66 (see Figs. 11 and 12) upon The pedestal the solid shaft 56. Upon the inner portion of the arm 62 I provide lugs 67, hearing adjusting stop-screws 68, which, as will be seen, are in direct line of travel of the arm 66 and serve to be engaged thereby.

The operation of moving a spike from the dies by the above mechanism is as follows, the parts being in the position shown in Fig. 9: The cam 55 acts to operate the forked arm 52 in. a manner to lower the shafts 56 and 49, together with the tongs, which latter are lowered while open into the recesses of the dies 10 and 16 in a manner to straddle the spike about midway of its length. The next operation is a one-quarter movement of the shaft 56, actuated by the segment upon the lever 59, which movement through the arm 66 and its connection 65 closes the jaws of: the tongs in a manner to firmly grasp the spike thereon. One of the screws 68 is so adjusted as to cause the arm 66 to abut thereagainst at the instant the spike is firmly clamped, at which instant the die 10 also moves backward, freeing the spike, and. at which time the forked arm 52 again acts in a manner to raise the shafts to the position shown in Fig. 9. Upon, being raised to said-position additional rotary movement is imparted to the shaft 56, which through the connection of the arm 66 and the screw 68 throws the tongs around to the opposite side, after which the forked arm 52 is again operated in a manner to lower the shafts, together with the tongs and spike,

which places the head of the latter between one of a series of pairs of jaws constituting holders mounted upon an intermittently-rotary table B, journaled in the bed. Upon being placed therein as above the jaws are closed u pon the head by mechanism which will later be described. After the spike has been grasped by the holder the tongs are opened, raised, and returned for another spike and the former operation repeated.

The intermittent rotary table 13, above referred to, will be next described, and attention is called to

Sheets

1, 7, and 8, which fully illustrate its construction and operation. Within the bed 1 is provided a bore 69, in which is journaled the hub of a ratchet-wheel 70, and to which is keyed the hub 71 of the table B aforesaid. To the under side of the bed I secure a bracket 72, Fig. 14, in which is mounted a vertical central post 73. Upon the upper end of the said post is secured a cam 74, which serves to operate the holders carried upon the table, as will presently be described. Upon said post 73 is also journaled an arm- 75, (see Figs. 14, 16, and 17,) carrying a pawl 76 to engage notches 77 of the ratchet-wheel 70, before mentioned, se-..

bell-crank lever is connected one end of a link 80, the opposite end of which is connected with and operated bya crank 81 upon a short shaft 82, journaled in the bed, the upper end being provided with a bevel-pinion 83, meshing with and driven by a similar pinion 84 upon the main driving-shaft. Said bell-crank lever is further provided with adjusting-screws 84, which are mounted in lugs of the arm 75. Forward movement is imparted to the table B from the main driving-shaft with each rotation thereof through bevel-pinions S3 and S4, crank 81, link 80, the bell-crank lever 78, and its arm 75. The purpose of the preliminary swing of the bellcrank lever from the position shown in Fig. 17 is to first disengage the holding-pawl 79, so as to free the ratchet-wheel. A continued movement of the link will cause said leverto strike the adjustable stop 84" upon the arm 75, which later through its pawl moves the ratchet-wheel and table just one-fifth of a turn, which movement is sufficient to carry a spike from one station to anotherviz., from the receiving-station C, where it is placed by the tongs, to the grooving mechanism, (designated by D,) or from the grooving mechanism to the pointing mechanism shown by E.

As before stated, the table B is provided with a series of holders F, all of which are of a similar construction, as will be apparent from Figs. 14, 15, and 18. Therefore I will refer to all with like reference characters. Each of said holders F consists of two jaws, one being fixed (designated by 85) and the other movable, which I designate by 86. The fixed jaw is secured to the table by means of a screw-bolt 87 and carries a steel grippingdie 89. Both said jaw and die are made adjustable by means of a screw 89, as shown. The swinging jaw is pivoted to the screw 87 and is also provided with a die 88, which latter is held in said jaw by means of a clamping-plate 90 and a screw 91, as shown. Said swinging jaw is further provided with a roller 92 upon its outer corner, which is for the purpose of engaging the several inclines a, b, c, and (1 upon the fixed cam 74..

From the foregoing it will be seen that with each intermittent rotary movement of the table the roller upon the several movable jaws will move upon the face of the cam and be engaged by the inclines aforesaid in the following manner: The roller of the movable jaw as it starts from the first station 0 rides up the incline a in a manner to move said jaw and clamp the spike and head, whereupon the movement of the table is continued until said jaws approach the grooving-station D, when said roller will ride up the second incline b, which causes the said jaw to further tighten upon the head and hold it perfectly rigid during the grooving operation, during which time the table stands still. A further movement of the table will carry said spike to the pointing mechanism E, the roll riding down the incline b, loosening up slightly on the spike-head until the pointing-station is reached, when, as before stated, a third incline cis reached and the head is again tightly clamped and held during the pointing operation. After the pointing is done and the spike is completed the table is given a further rotation, thus causing the roll of the jaw in question to ride down an incline d, which frees said jaw in a manner to release the spike, which drops from the machine at e. It is further obvious that the several holders F on the table operate successively and that there are spikes in three of them at all times.

The spike having been carried by the table B from the station 0 to station D is ready to be operated upon by the grooving mechanism, which will next be described. (See

Sheets

1, 9, and 10.) Upon the main driving-shaft 2 is a spiral gear 93, which meshes with and drives a similar gear 94 upon a shaft 95, journaled in boxes 96, secured to the main bed. Said shaft 95 is provided with a crank 97, upon which is journaled a box 98, slidably fitted in a yoke 99, with a reciprocating slide 100, mounted in boxes secured to the bed. Upon the forward end of the slide is mounted four pairs of cars 101, the side ones of which have pivoted thereto arms 102, which are normally thrown outward by means of a spring 103. Within the forward inner end of said arms are mounted grooving-rollers 104, which (see Fig. 21) serve to form the groove in the spike. Said rolls, as will be seen, are rotatably mounted upon a pin and their periphery is engaged by an intermediate roller 105, mounted in the arm 102 and engaging the track of movable block 115. To the top and bottom ears 101 of the slide are mounted arms 106, which like the side arms are provided with inner rollers 107, whose periphery is smooth and forms the flat side of the spike-shank. Said rolls are backed by intermediate rollers 108, the bottom one of which engages a track in the bed, while the top one rolls in a corresponding track in a bridging 109. The top and bottom arms and rolls, as will be apparent, simply have a common reciprocating movement, while the side ones have a reciprocal movement in addition to a slight inward and outward movement necessary to enter the stock of the spike and to spread open again when retracted to straddle the new blank to be grooved, as will later be again referred to.

Upon the shaft 95 are mounted two cams 110, which, together with their connecting parts, are exact duplicates of each other and work in unison therewith. Therefore I will refer to them with like characters of reference. Beneath the cams are mounted, in suitable ways 111, slides 112, which, as will be seen from Figs. 19 and 22, are provided with lugs 113, which engage the cam upon each side, so as to be positively operated thereby in both directions. The forward ends of the outside of said slides (see Figs. 20 and 21) are provided with a suitable dovetailllG, which slidably operates in a corresponding way in an adjustable block 117, the latterbeing secured to the main bed of the machine and made adjustable by means of screws 118.

The inner forward sides of said slides are in like manner p rovicled'with a way 114, which engages a corresponding way in a movable block 115,'which, as will be seen, is fitted between lugs 119 of the bed. The inner sur-.

the same inward, thus bearing the rib of the grooving rollers 104 into the spike, after which the slide 100 is drawn backward, thereby rolling the groove in the spike.

Having thus completed the description of the grooving mechanism, 1 will nextdescribe the pointing mechanism, by means of which a spike'is completed. 7

The pointing mechanism is fullyillustrated on Sheets 1 and 11, and consists of the following: Within boxes 120 is journaled a shaft 121, having bevel-gear connections 122 with the shaft 95 before mentioned, and by means of which the same is operated. Upon the opposite'end of said shaft 121 is secured a crank 123, bearing a link connection 124 with an arm 125 upon a rock-shaft 126, journaled in a suitable box secured to the bed. The, op-

posite end of said shaft is provided with a similar arm 127, which in turn is provided with a link connection 128 with a slide G, secured in ways 129 of the bed. From the above construction it will be seen that with each complete rotation of the shafts above named the slide G, together with the parts mounted thereon, will be thrown forward and backward, asdesired.

- The slide G consists of a specially-designed casting having a face-plate 130 and carries five longitudinal shafts, as will be apparent from Fig. 27. The main shaft 131 (see Fig. 24) is journaled in the central rear portion of the slide and is provided with a belt-pulley 132 upon its outer end, by means of which it is driven at a high rate of speed from an independent source. The inner end of said shaft is provided with a pinion 133, which meshes with and operates four larger pinions 134:, mounted upon separate shafts 135, jour-- naled in the slide,-as shown. Each of these shafts is provided with acrank 136, bearing a journal 137, which is slidably fitted in a reciprocating hammer 138, the latter being suitably mounted within recesses of the slide and covered by'the plate 130'aforesaid.

The forward ends of the hammers 138 are provided with hardened detachable heads 139, as fully appears in Fig. 28, which head in practice comes in direct contact with. the heated spike and operates thereon. As will be seen from a careful inspection of the position of parts shown in Figs. 25 and 26, the hammers are timed to operate in pairs, the upper and lowerhammers operating together and the side hammers voperating therebetween that is to say, the two side hammers being out in their extreme position while the upper and lower ones are at their inner extreme, thus allowing each to come closely together independent of the other. The operative end of the head 139 is slightly beveled, as will be seen from Fig. 24,which is to insure the proper tapering of the end of the blank. From the above construction it will be obvious that rotary movement is imparted to the several shafts 135 from the independentlybelted shaft 131 and that by such rotary movement a rapid reciprocal movement will be imparted to the hammers in question, the force of which is directly applied to the end of the spike. Said operation is started whenthe slide is nearing its extreme forward position and is completed at the beginning of the retracted movement of the same, which completes the portion into a head, rollers or their equiva-' lents provided with ribs for forming grooves in two sides of the shank portion, and mech-.

anism for pointing the end of said grooved shank.
