Application filed May 18,

T 0 all whom it may concern:

Be it known that I, GEORGE GoDnU, a citizen of the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Blank-Feeding Mechanisms, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to blank feeding and in particular to the feeding of strips or blanks of metal which are to be fashioned into nails, to the machines which form the nails. The embodiment shown in the drawings is particularly designed for use in connection with a nail making machine, which cuts a long strip of metal transversely into nails of a length corresponding to the width of the strip. It is the present custom to clamp the end of the strip in a follower forced. by a gravity feed to convey the strip down to the shearing knives-in the machine, which results in wasting about inch of metal at the end of each strip where it is gripped by the follower. It is necessary also for the operator to remove the follower and put in a new strip as soon as a strip is cut up, and as one operator cares for perhaps a dozen machines, it is not uncommon for a machine to run idle for some time While the operator is supplying a strip to another machine, or' for more than 5; inch of a strip to be wasted because of his inserting a new one before the old one is quite used up.

It is a principal object of 'my invention to lower the labor cost of operating these machines to a small fraction of its present amount and also to obviate this loss in material by providing a machine in which a number of blanks may be fed to and operated upon by the machine without attention from the operator and in which substantially all of each blank is utilized.

To this end an important feature of my invention resides in the provision of nail blank feeding mechanism organized to present a nail blank or strip in different operative relations to the operating means of the machine during consecutive operations of the operating means so that the nails may Specification of Letters Patent.

Patented Nov. 8, 1921. 1917. Serial No. 169,562.

be cut tapering with their large ends formed alternately from each side of the blank and so constructed and arranged that the supply of a fresh blank to the presenting means is automatically effected under the control of a blank in the presenting means. The invention in another aspect contemplates the supply of a fresh strip to the presenting means without suspending the presentation of the strip being operated upon to the operating means. Preferably, and as shown, thepresenting means comprises a, carrier movable about its axis to present the blanks alternately in different operative relations to the operating means, and the supply of a blank to the carrier is initiated by mechanism comprising a member which normally engages a blank in the carrier, said mechanism operating upon movement of the carrier aboutits axis subsequent to said member passing off the end of the engaged blank to occasion the supply of a fresh blank thereto.

An important feature of the invention resides in the provision of means operating to present a strip in different operative relations to the operating means during consecutive operations of the operating means and movable relatively to a magazine which is constructed to support a strip in endwisealinement with the presenting means and from which the strip is transferred to the presenting means. In the illustrated construction, the means for feeding the strip through the presenting means is spaced from the receiving end of the presenting means by a distance less than the length of astrip and a fresh strip is supplied to the presenting means prior to the'pas sage' of a, strip in the presenting means for engagement with the feeding means. Consequently, the fresh strips project from the presenting means when they are transferred thereto. To the end that the proper operation of the presenting means may not be interfered with, the means for supporting the strip for transfer to the presenting means, whether it be a magazine or of other nature, is constructed to permit rotation of the projecting end of the strip as the carrier turns to present the strip to the operating means.

In accordance with a further feature of the invention the blanks are supplied to the presenting means by mechanism constructed and arranged to receive a, plurality ment to aline the magazines successively with the blank presenting means, and at a proper time in the operation of the machine, the blank contained in the alined magazine is transferred to the presenting means.

Another featureof my invention is the organization of means for operating on a blank, means for presenting the blank to the operating means. mechanism for placing the blanks in the presenting means, and a conveyer for bringing the blanks into position to be operated on by the placing means.

Another important feature. of .my invention is its non-repeating characteristic. The control of the blank supplying mechanism is such that this mechanism cannot be operated twice in immediate succession, so as to place toomany strips in the machine at once. I accomplish this by rendering the initiating mechanism inoperative after having once actuated the blank supplying mechanism so? that it can not again actuate such mechanism until it has been reset by a new blank. This feature insures that strips will not be doubled up in the presenting means in case the first strip should for one reason or an other not be thrust all the way into the presenting means, inasmuch as the initiatin mechanism cannot be again operated until a strip has been thrust into the presenting means forthe required distance so 'as to.

reset the initiating mechanism and has been fed forward past the strip engaging memher.

Another feature of the invention relates to the manner of operating the presenting means to- .feed and position the blank for operation thereon by the operating means of the machine. These and other features of the invention ,comprising various combinations and arrangements of parts will be best understood which,

The nail making machine in connection with which my inventionis disclosed is the well known Perkins .machine, and need not be specifically described. Its frame 20, main shaft 22', stationary cutting die or anvil 24, movable cutting dies 26, 28, adjustable stop 29 and header 30 are all of well known construction. front carries the guide fingers 32, 34, the former'of which is heavy and is placed in the machine in seldom disturbed adjustment, while the guide 34 is light enough to spring slightly and is adjusted to the width of the particular nail blank or strip being used, by means -of the screws at 36. The front end 38 of this guide is cut-away slightly at -the top to crowd the 'end of the nail strip against the guide 32 as it descends.

Mounted on the main frame of the machine is a U-shaped bracket having arms 40, 42 in which a rotatable shaft 44 is mounted. Between thebrackets this shaft is eccentric to its bearings in the brackets and carries a block 46. Rotation of the shaft 44 adjusts the block toward and from the main frame by means of the eccentric, and a screw 48 on each of the brackets 40, 42 effects a lateral adjustment, the two'screws holding the block immovable between them.

The block 46 has two links 50 attached to it by bolts 52, and the outerends of the links are bolted between-head 54 and a yoke 56- carried by the head, by bolts 58. The

links 50 are notpara'llel, con-ver ing some-' what to'ward the left as seen in ig. 2, the purpose being to permit horizontal adjustment of the head 54 and the parts it carries about a center substantially at the front ends of the guides 32, 34. If the links were parallel the head 54 would swing straight Fig. 13 is a detail of a member of the trip- Fig. 15 shows this mechanism in-opera- The bed of the machine in j nail blank can be'obtained.

ment of the blank;

The machine to which the invention is illustrated as applied is designed to make nails of a form tapering from the head end to a narrow point. Inasmuch 'as the cutting dies 26 and 28 operate always in the same vertical plane, it is therefore necessary that the operative relation of the blank to the cutting dies be alternately changed in such manner as to cause the end of the blank to project farther beyond the cutting plane of the dies at one edge of the blank than at the other edge. To this end, a standard 66 on the frame 61 supports a yoke 68 connected to the standard 66 as indicated at 69 by an adjustable eccentric shaft 71, and mounted in two

bearings

70 and 72 of the yoke are the

journals

76 and 78 of a carrier or head 74 which presents the metal blank or strip :80 obliquely of the cutting plane of the dies 26 and 28. In the present embodiment of the invention, the operative relation of the blank 80 to the cutting dies is changed to-cause the blank to project always farther beyond the cutting plane of the dies at one edge of the blankthan at the head 74 and turning 180 after each operation of the cutting dies 26 and 28. It is to be understood, however, that the scope of the invention is not limited-to a construction in which the blank is presented in different operative relations to the operating means by rotative movefor example, the operative relation of the blank to the operating means may be changed by swinging the blank laterally about the point of operation of the operating means on the blank in a manner familiar to those skilled in the art of nail making.

The main shaft 22 drives a sprocket 82 which is adjustably bolted at 84 to a disk fixed on a shaft 86 mounted in the main frame. The shaft 86 carries an elliptical gear 88 meshing with another elliptical gear 90 on a shaft, 92 having universal joints at 94, 96, and extending forward to a bearing 98 in a block 100 vertically adjustable in a slideway 102 in the head 54 by a set screw 104 and abolt 106. The shaft carries an eccentric 108 at its front end, on which is boxed a yoke 110 having a turnbuckle connection 112 with ayoke 114-Which is universally jointed at 116 to the bearing 72.

guide slot 62 on a support 64 which is other by elevating the it through an angle of is shown a spring pressed latch Asprocket 118 is mounted concentric with the eccentric on the shaft 92, and drives a sprocket 120 on the journal 78. The connecting sprocket chain 122 is tightened-by the connection 112. The elliptical gears r0- tate the shaft 92 and its driven parts at an uneven rate of speed and the elements are assembled in such relation (the slots 84 providing an adjustment) that the head 74 turns rapidly when the eccentric 108 isat its uppermost position and turns most slowly while the eccentric is at its lowest point so that the movement of the head 74 is substantially m'Z while the shearing dies are severing the nail blank. The parts are shown in the lowest position in Fig. 1. It will be noticed that the strip carrying head 74 will rotate continuously in the same direction, its top moving toward the observer as seen in Fig. 1, instead of oscillating 180, as is the general practice in nail making machines.

The adjustment at 44 carries the entire feeding mechanism toward or from the shearing dies with an incidental variation in height; the links 50 permit an angular adjustment, the screws 59 give a vertical adjustment of the frame 61 and the parts carried by it; the screw.104 vertically adjusts the oscillatory path of the feeding head 74 about the center at 69 so that its lowest point will aline with the cutters; the adjustment at 71 horizontally adjusts the oscillatory path of the head 74 to aline with the guides and the adjustmentat'84 fixes the time relation of the feeding means to the operating or nail making means.

The bearing 70 is split and its cap can be thrown back on a hinge 124, (Fig. 2) exposing a longitudinal slot 126 (Fig.8) in the journal 76, for the reception of the nozzle 128, through which the nail strip is presented to the shearing dies. A different nozzle is-required for each width of nail strip used, and it is necessary that the nozzles be readily interchangeable. In Fig. 4 130 which engages the nozzle 128, keeps it from slip ping out of the head 74, and permits it to pivot in the slot 126. Undue pivotal movement toward the open side of the slot is prevented by the pin 135 (Fig. 2). This pivotal movement permits the blank 80 to move laterally when it contacts with the cut-away surface of the guide 34 and thus to settle between the guides 3234 without strain on the mechanismt The nozzle is formed of two plates 129, 131, Fig. 5, the former having a groove 133 which fits the nail strip, and the latter having a resilient member 135 which steadies the strip and frictionally holds it in position by pressing it firmly into the groove 133.

Mountedin the yoke 68 is a rock shaft 132 carrying a bent crank arm 134 which has bears on a rating sufiiciently a roller 136 on its its outer end. Keyed to the rock shaft is another crank arm 138 having a set screw 140 at its end. The screw face cam 142 mounted on a vertical pivot 143 on the yoke 68 and having a handle 144, and is held in contact therewith by a spring 146 which bears on the crank arm 138 and on an adjusting screw 148 in a In 1 on the yoke 68.

he nail strip is fed through the head 74 by mechanism which will now be described. The journal 78 has an aperture 150 collinear with the slot 126, through which the strip is fed. Two guides 152, (Fig. 11) relatively adjustable by a right and left screw 154, in a slideway 156, (Fig. 8) hold the strip in proper alinement as 1t feeds through. The head-of the screw 154 turns in a slot in the slide, as shown in Fig. 8. The head 74 carries a-pin 158 on which is rotatably mounted the feed dog 160, (Fig. 12). This dog is U-shaped, has a cam 162 on its central arm, and is recessed to receive a feed wheel 164, also mounted on the pin 158. The wheel comprises a corrugated roller 166 having its surface interrupted by an annular groove 168, and having a ratchet wheel '170 which is actuated by a spring pressed pawl 17 2'in the dog 160. The other side of the head 74 contains a bearing 174 in which is mounted a stud 176 on a plate 17 8 The plate carries another stud 180 on which is mounted a feed dog 182 with a cam 183 and a feed wheel 184 similar to those already described. The plate 17 8 also has a lug 186 engaged by a spring 188 which may be adjusted by a screw 190 in the head 74. This spring will swing the plate 178 and the parts it carries around the stud 176 to grasp the nail strip 80 between the two corrugated rollers on the feed wheels. 7

A stop 191 (Fig. 4) is provided to limit movement of the plate 178 in the outward direction. This keepsthe rollers from sepato permit two strips to passbetween them at the same time. With this construction a definite number of blanks greater than one might be fed if desired and all blanks resented in excess of that number rejected. hen a superflous blank is pre sented the feed rollers will either slip o'nits' end or look on it, the spring 146 yielding in the latter case to avoid any breakage, and the consequent movement of the

elements

138 and 140 serving to warn the operator that a superfluous blank is in the machine.

The

dogs

160 and 182 each have an ear v 192 engaged by a spring 194, (Fig. 3) which holds the two dogs against two stops 193 (Fig. 8) and 195 (Fig. 4), respectively, with their cams 162 -and 183 advanced to the right as seen in Fig. 3. As the head 7 4 revolves these camscome alternately in contact with the roller 136, and are pushedback in turn actuating the corresponding ratchet 170 and corrugated roller to feed. the nail I strip 80 toward the shearing dies. When the strip reaches the adjustable stop 29 which prevents further feeding movement of the strip and positions the strip relatively to the cutting dies,.the spring 146 is com-.

pressed by the reaction between the

cam

162 or 183 and the roller 136, sufiicient to allow the roller to pass over the tip of the cam. The position of the roller may be adjusted by the screw 140 to make the movement of the rolls accord with the extent of feeding movement of the strip permitted by the stop 29.. The adjustment of the roller 136 for-.

ward entirely out of the path of the cams 1.62 and 183, in case it is desired-to stop the feeding of the strip altogether. The roller- 136 is adjustable in a slot 197 (Fig. 3) in r the arm 134 so that the beginnin of the feeding movement can be timed. prefer to begin it while the head 74 is still descending, just before the end of the strip 80 falls on the die 24.

The nozzle 128 (Fig; 7) has a nose 196 which extends into the grooves 168 in the feed wheels so that a new nail strip which is fed down to the rollers cannot avoid the opening in the end of the nozzle, or slide off from the abutting end of the previous strip. This insures that each strip will feed the preceding strip completely to the nail makmg means, The "saving depends on the size of the blank and the amount of waste under present conseveral per cent. j

A little stub shaft 198 is mounted in a bearing 199 in the head 74, carrying a feeler illustrated as;a finger 200 which extends within the groove 168 in the feed wheel 184 and thereby economize material.

ditions, and in nail making will amount to and restsagainst the side of the nail strip 80. The purpose of the finger 200 and the associated mechanism now to be described is to initiate the supply of fresh strips to the head 74. The stub shaft has an arm 202 on its other end which hingedly engages a block 204 mounted to slide on the seat 206. A spring 207

in'the holes

208, 210, Figs. 8 and 9, pushes the block oiit so that the finger 200 is forced against the nail strip 80. The block 204 slides against another block 212, which is mounted in the seat 214. This block has a shoulder 216 (Figs. 10 and 13) which is engaged by the block 204, when the latter is projected outward,.as will be d scribed, and has along slot 218 in its bottom which receives a pin 220 in the seat 214 (Fig. 8). A spring 222 in this slot rests against the pin 220 and presses the end 221 be described. As the of the arm 202 as it of the block 212 back against the head 74. This spring is weaker than the spring 207, so that theblock 204 if free to move would move into contact with .the shoulder 216 and push the block 212 outward. When the rear in a seat 226 in the (Fig. 8) and controls the clutch hereinafter to be described which operates the strip supplying mechanism. A pin 228 extends into a slot 230 in the bar and a spring 232 thereby holds the bar toward the right in Fig. 2. The outer end of the bar is slotted at 234 and the side of the slot is beveled at 236. The block 212 has a corresponding bevel at 238 (Fig. 13), and when it is projected outward as above described, will enter the slot 234 and the two bevels will slide over each other as the head 74 revolves, pulling the bar 224 to the left as seen in Figs. 14 and 15, thus initiating-the supply of a strip to the head 74 as will hereinafter appear more clearly. As hereinbefore' stated, means are provided for rendering the initiating mechanism inoperative after the supply of a stripis initiated to insure that an excessive numberof strips will not be introduced into the carrier or head 74. Such means will now revolution of the head 74 proceeds, a cam bevel 240 on the block 204 will engage a lug242 on the frame 68 and the block 204 will be tipped about the end passes over the lug. This will take the block 204 out from engagement with the shoulder 216 of the block 212, which will then beretracted by the spring 222. The cam 243 holds the block 204 aside to allow ample time for this movement. The bar 224 will be forced back to its original position by its spring 232, as

' soon as the block 212 has passed through the slot 234. A wiper may be placed on' the head 74 in order to effect positively this movement of the bar 224, but I have not found it necessary. A lug 244 is mounted on the frame 68 to wipe back the block 212 in case its spring 222 fails to push it back. It is therefore impossible for the machine -'to repeat the tripping of the bar 224 until after the initiating mechanism has been reset by the raising of the finger 200 by a new nail strip, which will pull the block 204 back of the shoulder 216. Thus it is impossible to get several blanks into the machine at once, or to have the transferring mechanism in continuous repeated operation when the ma a-zine is empty.

ounted rotatably on the journal 78 adj acent to the sprocket 120 is a sprocket 246 having a lateral recess 248 in which is rocap 223 of the bearing 72 tatably mounted the journal 250 of a pawl 252, see Figs. 16, 17 and 18. A spring 253 tends to turn the pawl downward as seen in Fig. 17. The projecting end of the journal 250 is flattened at 254 and extends into a groove 256 in the sprocket 120. This groove has recesses 258. When the pawl 252 is lifted against the spring 253 the fiat 254 is cleared by the smallest diametered portions of the groove 256, as shown in Fig. 17, but when the pawl drops (Fig. 18) the journal swingsover so that the wall of a recess 258 catches'it and thereby causes the sprocket 246 to rotate with the sprocket 120. A holding dog is provided for the pawl 252, this, in the illustrated machine, consisting of a clutch controlling bar 224 on the end of which the pawl 252 normally rests. The pawl 252, however, slips off the end of this bar when the latter is drawn to the left (Fig. 15) .by the block 212, and after a rotation of the sprocket 246 is caught again on the bar 224 and lifted as in Fig. 17 after the block 212 has turned out of contact with the bar and it has been slid back by its spring 232. The

sprockets

246 and 120 are thus disconnected, and it is thus clear that the feeding of the end of, the nail strip 80 past the finger 200 causes a single revolution of the sprocket 246.

Although but one form of mechanism is herein shown and described for initiating the operation of the strip supplying means and for rendering said, initiatingmeans 1noperative until it is reset by the freshly supplied strip, it is realized that these features of the invention may assume various forms without departing from the principles of the invention or the scope of the appended claims. 7 j

The means for supplying fresh strips to the carrier 74 will now be described. Mounted on a shaft 260 in the bracket 66'is a conveyer for bringing the blanks into position for transference to the carrier by the placing means hereinafter to be described. Said conveyer comprises a turret having a plurality of magazines or tubes 262, for holding blanks 80 and supported at its outer end in a bearing 264, mounted on the frame 61. This bearing contains anti-friction rollers 266, Fig. 21. The inside ends of the tubes 262 are provided, with guides 268, Fig. 20, which normally aline 'with an aperture 270 in a plate 272 mounted on the standard 66. This aperture has a beveled edge 271 and alines approximately with the mean-position of thev bore'150 in the journal 78. The flange 27.4 on the end of the journal, is so wide that together with the bore 150, it covers the entire aperture 270 at all times. The movement of the head 74 about the shaft-71. carrie'sthe bore 150 across both edges of the aperture 270, so that a blank which is projected from its tube 262 W111 I either enter the aperture or will strike the flange and be pushed off into the aperture by carries a cam 286-which engages a roller 288 a on a cam lever 290 vertically pivoted at 292 on thebearing 264. The cam lever 290 carries an arm 294 whichextends over to' the other side of the machine and is linked to a slide 296- by a link 298. The slide recipro-v cates on a bar 300 mountedon the frame 61 andhas a cup 302 pivoted to it at 304. The cup 302 operates to place the blanks into the .slotted carrier or head 74, said cup transferring the strips to the head 74 from the magazines or tubes 262.

The magazines or tubes 262 are supplied with nail strips 80, each magazine being adapted to contain a single strlp, as shown and when the mechanism has been tripped .as described, the shaft 280 makes one revolution, throwing back the slide 296, and, by means of the member 282 and a tooth 284, rotating the turret one tube forward in the direction of the arrow, Fig. 19, thus bringing a new nail strip into alinement with the aperture 270. The steep part 306 of the cam 286 then permits the spring 308 to ull back the arm 294 and the cup 302 will rive the nail strip into the bore 150 (Fig. 4) down through the head 74 and under the finger 200, which will then return theblock 204 to its normal position, Fig. 10. The conical aperture 150 is flattened as shown in Figs. 9, and 17, so that the strip is guided into the roper position in the head.

Tie new strip feeds into the nose 196 against the end of the preceding-one and drives it down toward the shearing dies until only a small sliver of it remains unused.-

My invention therefore effects economy of material and of labor. since the attendant can fill the turret at one visit and need not return until itis empty or nearly so.

The ivotal mounting 304 permits the cup 302110 operator to stop the supply of strips stopping the machine.

The turret carries a face plate 310 having holes corresponding to the tubes 262, and

without adjustable by the clamp 312 whereby the e thrown over out of alinement with the nail strip to be fed and this enables the from the tubes 262 to the bore 150 with greater facility.
