Application filed February 20, 1917. Serial No. 149,949.

Commonwealth of Massachusetts, have invented an Improvement in Assembling-Machines. of which the following description, in connection with the accompanying drawings, is a specifiation, like characters on the drawings representing like parts.

This invention relates to assembling machines. the illustrated embodiment being designed to secure together the various parts of the turn-button fastener.

.\l v invention will best be understood by reference to the following description of an illustrative embodiment thereof taken in connection with the accompanying drawings, wherein,

Figure 1 is a side elevation of a machine embodying my invention, a part being broken away; i v

Figs. 10 and 11 are sectional views on a large scale showing the assembling mechanisms in different phases of their action;

and

Fig. 12 is a view of the assembled productembodying the parts shown in Fig. 2.

Figs. 5 to 8 are on the same scale much greater than that of Fig. 1 and substantlally twice that of Figs. 3 and 4.

The machine chosen for purposes of illustration is particularly adapted for assembling the parts of a turn-button fastener of known form, which are shown separated in Fig. 2 and assembled in Fig. 12. These parts include the base or body a, the head or button I). and the headed pin 0 encircled by spring (I. The base or body a is either a small casting or, as here shown, a stamping having a housing, the outer face of which is provided with intersecting grooves in which the head 6, usually a small casting, is adapted to fit, as clearly shown in Fig. 12. The body and head are connected together by means of the pin passing throu h the body at the junction of the grooves an entering the perforation in the head, which is shown dotted in Fig. 2. The head I; is thus resiliently held in one of the grooves of the base but can be turned, moving against the force of the spring d, to seat in the other groove, and thus acts as a button.

Referring to Fig. 1, I shall next briefly describe the general layout of the machine shown. The machine embodies a bed 1 supported at a suitable elevation from the floor by legs 3 which carry journal boxes for a main drive shaft 5; Suitable standards or brackets, not necessary to refer'to at the present time, support various mechanisms above the bed. The head portions 1) are herein fed from a suitable automatic assorting mechanism denoted generally by the numeral 7 to a chute 9. A receptacle 11 may be provided for the body parts a from which they may be fed to a suitable conveyor 13 herein taking the form of a rotatable dial, better shown in Fig. 7. A receptacle 15 may be provided for a supply of the pins 0 (which have previously been assembled with the springs d) to permit their convenient feeding to a chute 17. The various parts are brought together toward an operating point and suitable mechanisms select one object from each class and fasten them together, the operation of the present machine being to insert the pin a through the body a into the head I).

I shall neXt describe successively the mechanisms by means of which the various parts are brought to the operating point, disregarding for the time being the particular mechanical devices which transmit the proper motions thereto from the driving shaft 5.

I shall first describe the mechanism controlling the body portions a, and in doing so shall refer principally to Figs. 5 and 7. Mounted on the bed 1 of the machineis a conveyor which herein takes the form of a dial plate 13 having a hub 19 inset in the bed 1 and journaled on a bolt 21. At intervals may be crenelated, thus providing teeth 25-" adapted to co5perate with a driving pawl 27 mounted on a slide 29 which moves on the bed of the machine and pressed by spring 31 into engagement with the plate. If the slide is reciprocated it will be understood that the pawl will effect the rotation of the dial 19, the motion being controlled by suitable brake means illustrated in Fig. 7 as embodying spring-pressed pins 33 pressing against the face of the plate. A detent pawl 35 (Fig. 5) may be provided pressed by a spring 37 (which in the embodiment shown is disposed beneath the bed 1 of the machine and secured to a pin on the detent extend ing through a suitable slot) into engageinent with the teeth of the dial. The detent has an ear 39' adapted to coiiperate with a pin 41 on slide 29, so that as the slide, moves to the right in Fig. 1 in its non-driving movement it will throw the detent 35 out of cooperation with dial 13 and permit the pawl 27 to rotate the same in the left-hand movement of the slide. As the-slide finishes its driving stroke, however, the detent 35 will be released and permitted to enter between the teeth of the plate, thus preventing overthrow of the same. It will be understood by reference to Fig. 5 that at the left in that figure a number of the recesses 23 are presented in position to be filled by an operative with base parts a during the rotation of the dial, and that any suitable point Operating point, and in doing so shall refer chiefly to- Figs. 1, 7 and 5. In the present embodiment, as already stated, the head portions are automatically assorted by the mechanism 7 shown in Fig. 1 and fed in an endless series to the chute 9. I shall postpone the description of the assorting mechanism 7, since it is not essential to the invention in its broader aspects and since the heads might be fed to chute 9 by hand, entering the same in an endless series, as clearly illustrated in Fig. 7, and passing therefrom to a raceway 43 in the machine bed. As seen from that figure, the heads are all in the same relative position with their perforated sides facing upwardly. The raceway 43 leads beneath the periphery of the dial 13 to the operating point referred to, at whichposition the heads are abut delivered to a number of holding jaws const tuting a chuck located beneath the dial at this point, suitable escapement mechanism providing for intermittent deliverl'ay of single heads to the holding chuck. ferring to Fig. 5, the chuck may comprise a jaw 45 opposite the end of the raceway, the jaw herein consisting of a block mounted in suitable guides in the machine bed and having a slot in which works the obliquely disposed extremity of the slidably adjustable arm 47.

It will be understood from an ins ection of Fig. 5 that by adjusting the mem er 47 upwardly (as regards the figure), horizontal adjustment of the block 45 in its guides is effected, and that thereby centering of the button in one direction may be provided for. Coeperating with the jaw 45 are lateral holding jaws 49 adapted to seize the button at either side. The form of these jaws is best seen in Fig. 6. As there shown, they consist of hardened steel blocks mounted in recesses in suitable sliding members 51 and having their gripping faces disposed somewhat at an angleto accommodate the shape of the head I), as illustrated in Figs. 10 and 11 and also to form an abutment against downwardly exerted shocks, as will hereinafter be more fully apparent. The jaws 49 against hardened steel pins 53 in the slides 51 which take up the wear on the slide members 51 which would otherwise be excessive and soon impair the accurate fitting of the jaws totheir work. The remaining member of the chuck is best seen in Figs. 6 and 7, and comprises a jaw 55 adapted to support the button from beneath and forming an abutment, and also having another function which will presently appear, this jaw 5-5 being mounted in a vertical slide 57 -moving in the guiding bracket 59 which dends from the bottom of 'the machine bed 1.

I shall next refer to Figs. 5 and 7 for the purpose of describing the escapement by means of which the buttons are released one by one to the chuck. Mounted adjacent the delivery end of the chute 9 is a slide 61 moving in guide 63 and normally carried to an extreme right-hand position by a spring 65.. Mounted on the slide 61 is a pivoted lever 67 having a nose portion 69 in the shapeof apin extending in a direction sloping forwardly somewhat, as shown, into the path of the heads in the shute 9 and the raceway 43. A spring 71 normally presses this nose portion or pin into the raceway, as shown in Fi 5, and it constitutes an apparatus somew at like a ratchet pawl. The slide 61 is mechanically retracted to the left by means not necessary now to describe, and in this movement the lever will swing against the spring 71 and the pin 69 will ride over the heads in the chute, since a considerable number of such heads forming a heavy weight oppose their retrograde move ment. Having reached the end of its I-efthand travel, the pin is pushed by the spring 71 between two of the-heads, and when the slide is released to the action of the spring 65 the pin will push forward the row of pins in the raceway a distance equivalent to the width of one ofthe heads, and the head at the right-hand terminus of the row is delivered to the

jaws

45, 49, and 55 which are actuated at a proper time to close thereon.

In the operation of the present machine, the spring encircled pins 0 are' driven by a suitable driving mechanism through the body portion a held by dial plate 13 at the operating point and into the head portion 5 supported therebeneath in the chuck referred to. I shall first describe the means by which the pins are herein shown as introduced to the driving mechanism, and in so doing shall refer particularly to Figs. 6, 10 and 11. The

' pins are introduced, herein by hand, each in the same general osition, to the chute 17 and are delivered t ence one by one by suit ableescapement mechanism to the angularly disposed feed chute 73 delivering directly to the driving plunger. I herein show a member 75 mounted on a suitable bracket adjacent the delivery end of the chute 17 and providing guides for two sliding bars 77 having terminal .detent rods 79 entering the chute through lateral perforations. The springs 81' normally urge both bars to a right-hand extreme position, and means are provided for operating them against the force of these springs, herein shown as a lever-83 pivoted to the member 75 and adapted to be rocked by means of the crank arm 85 and the pitman 87 secured to the crank arm by a lost-motion connection. The pitman takes motion properly timed with respect to the movement of the fastener driving mechanism hereinafter described from a vertical slide 89 connected thereto by arm 91,

the lost-motion connection referred to being to step down in proper degree the throw of slide 89. As the lever 83 is rocked, its opposite ends cooperate with pins or other abutments on the sliding bars 77 and draw the same alternately to the left against the force of springs 81. Referring now to Figs; 10.

and 11,-the cycle of motion of this escapement can be traced. The parts being in the position shown in Fig. 11, the lower rod 79 projects across the mouth of the chute 17 and supports-the row ofpins therein. The upper rod 79 has been withdrawn to the left by the rocking arm 83. In this position the slide 89, shown in Fig. 6, is depressed, and the'lever 83 has been rocked by pitman- 87 to the position' opposite to that illustrated in Fig. 6. The slide 87 rising, theupper bar 77 is released to the action of its spring and the upper rod 79 is thrust resiliently in-v thus supporting all but the bottom pin. The lower rod 7 9 is next retracted to the left by the action of the lever 83 in moving to the position shown in Fig. 6 and the lowermost pin-of the series is free to drop from the chute 17 into the open mouth of the feed chute 73 which is then presented adjacent thereto, as shown in Fig. 10. It will thus be seen that I 'providefor the separation of the pins one by one from the supply and their delivery to the operating point for assembly with the bases and heads.

I shall next briefly describe the in driving mechanism which is situated a ove the operating point. Referring to Figs. 6, l0 and 11, the driving mechanism includes apin uide or sleeve which may take the form of a ollow block 93, the lower end of which is split to receive a renewable tubular portion 95 which forms an extension of the bore of the guide and is clamped in position by the blocks 97. The feed chute 73 already referred to opens laterally to the bore of the pin-guidin portion of the driving mechanism. T e guide 93 is supported by bracket 99 from slide 89 and thus has a vertical range of movement hereinafter more fully to be described. In the guide 93-95 works a plunger 101 carried by the bracket 103 on slide 105 which moves vertically in a path parallel to the slide 89. By proper movement of the slide 105 relative to the slide 89, the plunger can have driving movement in the pin guide 93. The shank of the plunger depending from the bracket 103 may be provided with suitable nuts 107 forming stops coiiperating with the guide 93 and its bracket 99 to prevent excessive descent of the plunger in the guide.

I shall next describe the cycles of motion of the parts already referred to, referring chiefly to Figs. 7, 10 and 11. Referring to Fig. the dial plate 13 or other conveyer is intermittently rotated, carrying body arts in the various recesses 23. While it is in motion the slide 61 is released to the action of the spring 65 and one of the heads b is fed forward to the chuck beneath the periphery of the dial 13. The dial is halted by the positive detent 35 (Fig. 5), with one of the recesses 23 in position directly beneath the pin-driving mechanism and directly. over the chuck. One of the heads is loosely positionedby the

jaws

45, 49 and 55 beneath the same. The next movement is an upward movement of the jaw 55 to press the head in place in the groove of the body a resting in recess 23 of the dial. Thereafter the lateral jaws 49 move inwardly and engage the sides of the head firmly but without excessive pressure. The parts are then in the position shown in Fig. 10. Referrin to Fig. 6, as well as to Figs. 10 and 11, the parts being in the position shown in Figs. 6 and 10, the slide 89 begins to move down into the guide 95. At this time the sleeve 93 and its auxiliary guide '95 are in the position shown in Fig. 11, and the auxiliary guide 95 is pressed against the bottom of the 'body member a and in coiiperation with the jaw holds the two firmly together in the position in which they are finally to be with the head 5 entering the groove of the body a. The plunger 101 has lagged behind in the movement of the sleeve and guide, but it now, under the action of the slide 105, overtakes the sleeve in which it works and striking the top of the pin which hasbeen admitted to the auxiliary guide 95, drives it through the opening of the body portion a and into the hole in the button head 5, which is supported by jaw 55 and the obhquely disposed jaws 49. The jaws 49 are then moved toward each other to compressthe head about the end of the pin, firmly gripping the latter therein. To faclhtate this attachment the pin may be roughened conveniently, as shown, by forming suitable threads thereon. The several parts of the driving mechanism are then retracted to their initial position, this retraction operating the escapement rods 79 as already described to deliver another pin to the feed chute 73. The holding action of the several jaws of the chuck will then be relaxed and the jaw 55 be given a second lifting motion to bring it to the position shown 1n Fig. 6, thus releasing from the chuck the head which has been fastened to a body portion. The completed fastener will rest loosely in the recess 23 of the dial plate and may be carried away thereby. The jaw 55 will then be retracted, the dial will bring another body member to the operating point and the slide 61 will be operated to feed another head to the chuck. The completed fasteners which are carried around by the dial may be completely removed therefrom by means of a suitable releasing plunger 107 normally depressed by the spring 109, shown in Fi 1, and adapted to strike upwardly throng recesses 23 as they arrive at a certain point in their rotation. The .completed fasteners are thrown into a chute 111, shown in Fig. 5, leading to any convenient storage receptacle. A housing 113 may be provided to catch the fasteners as they are thrust upwardly by the plunger 107 and guide them to the chute 111.

In order to enable those skilled in the art to construct a machine having the cycles of motion referred to, I shall next describe briefly a suitable set of mechanical devices 1,aaa,uss

for effecting such motion, the description referring principally to Figs. 1, 3 and 4. The parts so far described are c erated by suitable cams on the main sha tion of the dial is effected by a suitably designed roove cam v115 operating a pitman 5. The rota- 117 whlch rocks bell crank lever 119 (Fig;

1), the'other arm of which is connected by link 121 to the slide 29 already referred to (see Fig. 5). The motion of the slide 61 controlling the feedin of the heads, is effected by abell crank ever 123 which takes motion from the edge of a cam 125. The cam, as shown inliig. 1, has a suitable rise to throw the arm of the lever, shown in Fig.

7, toward the left, thus drawing the slide 61 to the left against'the action of spring 65, and releasin it at proper time for movement to the rig t by'said spring. The cam 125 is a groove cam as well as an edge cam and controls the motion of the jaw 55 of scribed. The lateral jaws 49 are operated from the groove cam 127 shown in detail in Fig. 4. The groove in the cam cotiperates with the cam'roll on the connecting rod 129. The design of this connecting rod 1s similar to that of the connecting rod operating the jaw 55 and two connecting rods hereinafter to be referred to, and may be briefly noticed here, it being loop-shaped to embrace the shaft5. The connecting rod 129 operates a block 131 moving in suitable guideways 133 and connected by toggle links 135 with two levers 137 ivoted to the frame at 139 and having their opposite ends (see Fig. 6) connected herein by links 141 and adjustable I-bolts 143 to the slides 51 which operate the jaws. In Fig. 4 the cam 127 is shown in a position where it is about to close the jaws 49 prior to the driving of the pin. The illustrated form of the cam groove clearly exhibits the various movements of these jaws. The motion of the slides 89 and 105 (see Fig.

6) is effected by groove cams 145 and 147,

respectively, (see Fig. 3). The toggle operating cam,127' is also formed as an edge cam having a rise 149, clearly seen in Fig. 4. This moves the bell crank 151 pivoted on the bracket 153 which operates the knock-out plunger 107. I have deemed it unnecessary to illustrate or to describe in detail the construction of the various cams referred to, as any skilled mechanic can construct them in such manner as to effect the motions desired. It will be understood that when the shaft 5 is rotated, for example by power applied through pulley 153 secured thereto by clutch 155, the various parts will operate as I have described. The shaft 5 may also be provided with a hand wheel 157 (Fig. 3) to permit it to be turned overslowly so that the operation of the machine may be watched and adjustments facilitated 1) having opposed arms 161 and 163 (Fig.

vided to receive a number of the-heads tobe 8) connected by a rod 165 which forms a journal hearing. A suitable hopper' is proassorted and delivered to the assembling mechanism, which hopper may be formed of a substantially semi-circular, fixed, dished plate 167 cooperating with the flange or rim portion 169 of a dished disk wheel 171 which forms the other side of the hopper. The flange or rim 169 also acts as a circulating conveyer mechanism for the buttons. To drive this mechanism the hub of the wheel is journaled on the rod 165 and may be driven by'the pulley 173. The rim 169 of the wheel is cut away or crenelated to form three-sided pockets 175, and plates 177 are formed to fit between the teethat the edge of the rim and they serve -as fourth sides for the pockets, as indicated in Fig. 9. The plates 177 are mounted on bolts 179 extending through the of the wheel and normall pressed inwardly by spr1ngs 181 encircling the bolts and bearing between the enlarged heads 183 of the same and a portion of the rim. A spacing washer 185 is provided to limitinward movement of the plates 177. A pocket is thus provided of variable effective area, the minimum being that when the plate 17 7 is pressed by spring 181 against the spacing washer 185 substantially as shown in Fig. 9. The pockets are so proportioned that one of the heads I) may be received in the same, as shown in that figure, and will be held by the pressure of the movable wall 177 thereagainst.

If the wall 177 is moved outwardly to the position shown at the bottom of the wheel in Fig. 8, against the force of spring 18 1, the effective size of the pocket will be increased and one of the heads may easily enter the same. The pocket, however, is

" so proportioned that the oblong and tapered head shown in Fig. 9. If now the wall 177 1s released to the spring 181 and drawn to the left, the effective area of the pocket will be reduced and the plate 177 will grip the head and hold it fast.

Adjacent the lower part of the wheel can enter in one position only, that means'are provided for ressing the gripping plates 177- to the rig t so as to permit heads from a mass disposed in the hopper to be received therein. For this purpose an arc-shaped plate 189 is provided having hubs or sleeves 191 mounted on cross-bolts 193 and held by stiff springs 195 in close proximity to the rim 169 of the wheel. The springs 195 may be mounted as shown, between the plate 189 and adjusting nuts 197 threaded on the cross-bolts 193. The heads 183 are adapted to ride along the side of plate 189 which will move pressing the plates 177 away from the washers 185 and opening the pockets for the receipt of the heads I). As the heads 183 ride off the plate 189, the bolts are released to the action of springs 181 and the'plates 177 will close on and grip the heads I) which may have been admitted to the pockets and permit the wheel in ,its rotation to carry them around without danger of their falling out under gravity. By this means the buttons are assorted into proper position and brought to the top of the wheel (see Fig. 1) where they are presented to the intake end 199 of the chute 9.. The chutehas been broken away in Fig. 8.in order not unduly to complicate the figure. When the heads b which are housed in the pockets of the conveyer reach the chute, means are provided for releasing them so that they may fall therein. In the present instance I have shown a roll 201 journaled on a bolt 203 suspended by a bracket 205 beside the rim of the wheel at its uppermost portion. The heads 183 of the bolts controlling lates 177 will ride upon the roller 201, thereby moving the plate away from the washer 185, as clearly seen at the them to the right,

wheel 207 is provided to act as a stirrer and this wheel preferably is rotated in a direction opposite to that of wheel 171. The wheel 207 may have a hub mounted on the supporting rod 165 and carrying a miter gear 209, takingmotion from miter gear 211 on the hub of the driven wheel 171 through an idle gear 213 mounted for rotation on a post 215 projecting from a sleeve 217 which is non-rotatably secured on the rod 165.

In Fig. 8 I have also shown a tapper acting on the chute 9 for facilitating the descent of the column heads or buttons therein. This tapper takes theform of a lever 219 pivoted,on a bracket 221 which pro ects from arm 161 and having a head 223 normally pressed into contact with the chute 9 by a spring 225. The opposite end of the lever has a beveled toe portion 227 which extends into the path of the series of radial pins 229 rojecting from the rim 169 of the hopper wheel. As the wheel. revolves 10 the pins 229 will act to rock the lever against the force of spring 225 and thus cause the head 223 to tap against the side of the chute 9, jarring the same, so as to feed downwardly therein the column of heads delivered thereto by the asserting mechanism described.

I have described with considerable detail the embodiment of my invention chosen for purposes of illustration, and followed out the various mechanical devices illustrated in the accompanying drawings, in order that the structure and operation of the machine disclosed may be abundantly clear.
