Application filed March 26, 1924. Serial No. 701,978.

To all whom if may concern:

Be it lrznown that l, EDMUND S. SPINNnr, of Abington, in the county of Plymouth and State of h/ilassachusetts, ya citizen of the United States, have invented a new and` useful lmprovcment in Machines for Setting lf'iyelcts, Rivets, and the like. of which the following is a full, clear7 and exact description, reference being had to the. accompanying drawings, forn'iing a. part of this specification, in explaining its nature.

The present invention relates to a machine for set-ting eyelets,`rivets and the like.

The object of the invention is to provide a machine of the above character which is simple and economic in its structure, etti cient in its operation and Will maintain its` efliciency. and not easily get out of ordcr o-r Wear out.

The invention can best be seen and` understood in the light of the drawings where anembodiment thereof is shown and in which- Figure 1 is a side elevation of the machine.

Fig. 2 is a plan.

Fig. 3 is a section taken on the line of Fig. 2.

Fig. it is a section taken on the line 't-4|; of Fig. 2.

Fig. 5 is a` section taken on the line 5 5 of Fig. l.

Figs. G and 7, respectively, are side elevations of that part. of the machine carrying the punch and setting mechanism later to be referred to, the figures showing different operative positions assumed by the respective mechanisms in the operation of the machine.

Referring to the draivings:- t

1 represents the frame of the machine. The frame is provided With an under eX- tending part 2 and overha-nging the same an extending part 3 with space 4 between the two parts. Mounted within the space t is al Work table 5, having Within it an opening 6, arranged preferably in an in clined position as shown which is supported by a bracket 7 secured to the extension 2 of the frame.

lvfouuted upon the frame extensions 2 and 3 are punch and setting mechanisms. The punch mechanism comprises a punch proper the The anvil has a top surface 14 having thel same inclination as the 'table in order that it may assist in the support of the Work on 'the table during the punching operation, as will later be more fully explained. The anvil 1s also provided With a recedingcentre or core 15 which also assists in the support of the Work during the punching operation and by its permitted recession into the anvil and carrier therefor permits of the punch. 8 ente-ring the anvil after passing through the Work when the respective punch members are brought into an engaging position with relation to the Work.

The setting mechanism comprises a member 16 having an annular clenching surface 17 and extending from this surface a central tubular projection 18 which enters the centre of the eyelet during the setting operation. The member 16 is borne by a carrier bar 19 mounted to slide Within aV Way 2O in the part 3 of the frame.

Arranged in opposition to and cooperating with the setting member 16 is a setting member 21 having an annular clenching surface 22 and a spring linger 23 adapted to receive eyelets from an automatic feed during the operation of the machine, as Will later be explained. During the setting operation the spring 'linger 23 recedesinto the setting member 21 and carrier therefor the clenching surfaces 17 and 22 of the respective setting members are brought into engagement with the eyelet or Worlr and the projection 18 of the member 16 enters the centre of the eyelet. The settingV member 21 is borne by a carrier 24 slidab-le Within a Way in the part 2 of the frame.V

The cooperating members and caigriers therefor of both the punch and setting mechanisms are mounted in opposition to one another above and below the table and are slidable upon the frame with a reciprocating motion toward and away from one another and the opening in the table into and out of engaging positions. The neinbers of the respective mechanisms preferably all lie in the same plane, which plane is a right angle to the face of the table. The respective mechanisms are also arranged in positions angular to one another and operate along lines having relatively such acute angularity that as the mechanisms are successively operated they will engage the work relatively to the opening in the table at a substantially common point, the punch mechanism engaging the work when the setting mechanism is in its disengaged, and preferably extreme disengaged, position, and vice versa.

The means for operating and assisting in the support of the punch and setting mechanisms is also such thatthe two mechanisms will engage the work in such relation to the opening in the table and work laid thereon covering said opening, that the work will not be elevated above the opening or depressed into the opening during the punching and setting ope-rations. In other words, during the punching operation the member 11 of the punch or anvil will be elevated to a position where its top surface 14 will lie substantially within the plane of the top surface of the table and will accordingly support the work immediately adjacent the point where the hole is made in it as the other cooperating punch member 3 or punch proper is passed through the work. In a similar manner during the setting operation the member 21 of the setting mechanism will be brought up intoV a position where its clenching surface 22 will lie substantially within the plane of the top surface of the table as the clenching surface 17 of the other cooperating member is brought down into engagement with the eyelet for upsetting it. The under clenching surface 22 of the setting mechanism will accordingly assist in the support of the eyelet during the setting operation.

It will also be observed that the respective members of the setting mechanism operate along a line or path substantially at a right angle to the plane of the table in order that the respective clenching surfaces of the setting mechanism may squarely engage the eyelet for effecting a. proper upsetting thereof in relation to the work. VSuch disposition of the setting mechanism necessitates that the punch operate at a slight angle with relation to the work with a tendency to make Van inclined opening through the work, but

such inclination is negligible in practice.

Reference will now be made to the means for operating the punch and setting mechanisms:

Both mechanisms are operated directly by a pair of levers and 31. These levers are mounted on a shaft 32 which has bearing to turn on the frame jlust back of the opening 4 between the parts 2 and 3 of the f ame. The lever 30 is provided with a hub 33 by which it is mounted to turn freely on the shaft 32. The lever 31 is provided with a hub 34 by which it is mounted on the shaft 32 and is secured thereto'by a setl screw 35 by which the lever 31 is secured to the shaft to turn therewith.

The two levers 30 and 31 are siinultane ously actuated by a crank shaft 3G through a connecting crank 37. The crank shaft 36 is mounted to turn on the frame of the machine and is turned by a power-driven pulley as will later be explained. The levers 30 and 31 besides operating the members of the punch and setting mechanisms assist also in the positioning of these members.

The general form, arrangement and operation of the levers are as follows: rl`he lever 30 forward of the shaft 32, on which it is mounted to turn, is bifurcated to provide arms 39 and 40 respectively, the arm 39 having a slot 39 therein and the arm 40 a slot 40 therein. That portion of the lever extending to the rear of the shaft 32 comprises an arm 41 having within it a slot 41. It is also to be noted that the lever is provided with an offset 42 by which the arm 41 thereof is slightly offset from the plane of the arms 39 and 40. to permit of the insertion of one of the crank arms of the crank mechanism later to be referred to.

The lever 31 in the part thereof lying forward of the shaft 32 to which the lever is secured is bifurcated to provide arms 43 and 44 respectively. The arm 43 has in it a slot 43 and the arm 44 has in it a slot 44. That portion of the lever lying to the rear of the shaft 32 comprises an arm 45 having in it a slot 45. The slotted arms to the bifurcated portions of the respective levers extend by the sides of the parts 2 and 3 of the frame in which lie the various movable carriers for the punch and setting mechanisms. Slots 47 are formed in the frame parts 2 and 3 in the sides of these parts facing the projecting arms of the respective levers. These slots extend in directions parallel with the various carriers of the punch and setting mechanisms and lead respectively into the ways in which the carriers reciprocate. Secured to each one of the carriers is a stud 43 extending laterally therefrom through the slot 47 adjacent the carrier7 and thence extending to be contained in one of the slotted arms of the two levers 30 and 31. ln this connection it will be observed that the stud 43 on the carrier 9 for the punch member 3 is contained within the slot 43 in the arm 43 of the lever 31, and the stud 43 on the carrier 12 for the punch member or anvil 11 is contained within the slot 40 in the arm 40 of the lever 30. On the other hand, the stud 43 on the carrier 19 of the setting member 16 is contained within the slot 39 in the arm 39 of the lever 30, while the stud 43 on llt) the carrier of the setting` member 2l is contained within the slot ll in the arm L14 of the lever-3 Thus arranged-the various carriers of therespectivepunch and setting',` mechanisms and members carried thereby will be nroperly actuated as the levers and 31 are turned in reverse directions.

As previously noted, thelevers 30 and 3l are actuated simultaneously by a crank shait 3G through a connecting crank 37. The crank 37 is a doublevacting crank. lt has a crank arm 5l lixed to the end et the crank shaft 36. This arm bears upon its end a laterally-extending crank pin 52 which is contained to lie within the slot in the arm Ll5 et the lever 3l. The crank pin .52 has secured tov it a crank arm 53 which lies between the arms el and 45 of the respective levers 30 and 3l and extends in a direction reverse to the direction of' the crank arm 5l through the axis ot the crank shaft, if such axis were extended, the extension of the crank arm beyond the axis of the crank shalt beinga dist-ance substantially equal to the length oi the crank arm 5l. The crank arm bears upon its end a laterally-extend ing crank pin .Vi-il which is contained within the slot 43:1 in theiarin 4l ot the lev r 30.

The normal position ot the part-s is substantially that shown in Figs. l and` 2. The levers 3() and 3l will beturned to a position where they will hold the respective members of the punch and setting mechanism in disengaged position. The arms l1 and l5 oit the respective levers 30 and 3l together with the. slots l-'t and Lio in 'these are s will occupy a horizontal position in substantial parallel alignment with one another and the respective crank arms 5l and 53 oit' the crank will have a similar horizontal disposition, their avranggen'ient also beingl such that the crank pin a? will be located at the outer end of the slot in the arm lo of the lever 3l and the crank pin 5l will be located at the inner end oi' the slot ll in the arm AYill ot the lever 3f).

lilith the parts thus disposed and arranged, the turningot' the crank shaft 36 a sii le revolution in a clockwise direction as rved from the side ot the machine shown o5 in l. l will cause the various parts to function as follows: As the crank shaft is turned `the crank arm 5l will move the crank pin :'32 inwardly along the slot 45 in the arm ot the lever 3l and will elevate this arm and, by the roc g oli' the lever, depress its arms i3 and lll, whereupon the punch mem bei' or the punch mechanism actuated by the arin 43 oiE the lever will be moved to an engaging position. weile the member 21 of the setting` mechanism` will be moved by the arm lll of the lever into a more retracted position. Simultaneously with this operation the crank arm 53 will move the crank pin 54 outwardly along the slot 4l in the arm 4:1 of the lever 30 and will depress this l (Y b se The extreme engaging position of theV punch member 8 will be reached when the crank shaft has been turned substantially one quarter oi? a complete turn and the crank. arm 5l is in a position at substantially right angles to the slot e5 in which the crank pin 52 is working. As the movement of' the crank shaft continues up to substantially a one halt complete turn the continued movement of the crank `arm 5l will move the crank pin 52 further inwardly along the slot 45 in which it is working and there upon the rockingl movement ol'" the lever 3l will be reversed and the punch member 8 of the punch mechanism and the member 2 of the setting mechanism will be moved back to their normal disengaged positions,

The extreme engaging' position ot the punch member or anvil 1l will be reached when the crank shaft has been turned substantially one quarter of a complete turn and the crank arm 53 is in a position at sub stantially right angles to the slot 411" along which the crank pin 5e is working. is the movement ofthe crank shaft continues up to substantially a one half complete turn the continued movement of the crank arm 53 will move the crank pin 5ft `further outward alongthe sl'ot lll in which it is working` 'and thereupon the rocking movement of the lever 30 will be reversed and the punch member' or anvil ll of the punch mechanism and the member 16 ot the setting' mechanism will be returned to their normal disengaged positions.

During' the operation just described the punch member or anvil ll will have been moved to its full originan'ing` postion with the face lll or" the anvil. suhstantiz'ally flush with the top surface of the table just prior to but practically sin'iultaneously with the time when the punch member 8 has been moved to a proper engaging position for making a hole in the work to receive the eyelet. Vhen the punch member or anvil ll has reached its lull engaging position and the punch member 8 has :functioned a. aoresaid the member will be moved away from its engaging position, but the en eagcnnmt ot the member 8 will continue until the crank arm 5l has been moved to a position et substantially right angles to the slot 45 in which it is working. By the recession of' the anvil ll its surface le will move below the face of the table on which the work is resting and consequently the work will no longer be supported at the point or the opening` in the table by the top surface 14 of the anvil at the very time when the member 8 of the punch is continuing to operate. Consequently the work will be slightly depressed by the punch member 8 into said opening. This is undesirable and is obviated by preventing a continued movement of the lever 31 operating the punch member 8 after this member has reached its proper engaging position for making a hole in the work. It is accomplished by making a. slight offset GO in the `arm 45 of the lever 31 along the top surface of the slot 45 therein. This offset is so postioned that the crank pin 52 working inwardly along the slot 45 will, after the crank arm 51 has moved the punch member 8 to a proper' engaging position, reach the offset and thereupon will cause a lag in the operation of the lever 31 and consequently the engagement of the punch member 8 with the work will no longer be continued `after the depression of the anvil 11 has commenced. After the crank pin 52 has passed the oifset then the rocking movement of the lever 13 will be continued and both levers will return the members of the punch and setting mechanisms to their initial disengaged positions.

Thus far the operation attending a substantially one half complete turn of the crank shaft has been explained. The crank pin 52 will then be occupying its extreme inward position within the slot 45 in which it is working and the crank pin 54 its eX- treme outward position in the slot 41. As the movement of the crank shaft continues the crank pin 52 throughthe operation of the crank arm 51 will work outward within the slot 45 in the arm 45 of the lever 31 depressing this arm and, by the rocking of the lever, elevating its arms 43 and 44. Thereupon the punch-member 8, actuated by the arm 43 of the lever, will be moved into a more disengaged posit-ion, while the member 21 ot the setting mechanism will be moved by the arm 44 of the lever into an engaging posit-ion. Simultaneously with this operation the operation of the crank arm will move the crank pin 54 inwardly along the slot 41 in the arm 41 of the lever 30 and will accordingly elevate this arm and, by the rocking of the lever, depress its arms 39 and 40. Thereupon the punch member or anvil 11 will be .moved by the arm 40 of the lever 30 into a more disengaged position and the member 16 of the setting mechanism will be moved by the arm 39 of the lever 30 into an engaging position.

kThe full engaging position of the setting member 21 will be reached when the crank shaft has been turned substantially a further one quarter turn beyond its half turn and the crank arm 51 is in a position at substantially right angles to the slot 45 in which the crank pin 52 is working. As the movemechanism will be moved back to their normal disengaged positions.

The extreme engaging position of the setting member 16 will be reached when the crank arm 53 is in a position at substantially right angles to the slot 41 in the arm 41 of the lever 30 in which the crank pin 54 is i working. As the movement of the crank shaft continues up to the time of its complete turn the continued movement of the crank arm 53 will move the crank pin 54 further inward along the slot 41 in which it is working and thereupon the rocking movement of the lever 30 will be reversed and the member 1G of the setting .mechanism and punch member or anvil 11 of the punch mechanism will be returned to their' normal disengaged positions.

During the operation just described the setting member 21 will have been moved to its full and proper engaging position with the clenching face 22 of this member substantially flush with the top surface of the table just prior to but practically simultaneously with the time when the said member 16 has been moved to a proper engaging position for upsetting the eyelet. When the setting member 21 has reached its full proper' engaging position and the setting member 1G has reached an engaging position to properly cooperate therewith for upsetting the eyelet then the member 21 will be moved away from its engaging position, but the member 16 will continue to be moved in the direction of a more extreme position of engagement until the crank arm 53 has been moved to a position at substantially right angles to the slot 41 in the arm -1-5 in which it is working. By the recession of the setting member 21 its clenching surface 22 will move below the face of the table on which the work is resting and consequently the work will no longer be supported at the point of the opening in the table at the very time when the setting member 16 is continuing to operate. ln other words, the setting member 1G will follow the setting member 21 as it recedes and consequently the work will be slightly depressed into the opening in the table. This is undesirable and is obviated by preventingl a continued movement of the lever 30 for operating the setting member 16 after this member has reached avproper position to cooperate with the sett-ing member 21 for upsetting the eyelet and before the member 21 has receded. It is accomplished by making a slight ott'- set 61 in the arm 41 ot the leverBO along` the top snriace ot the slet All therein. This oil'set is so positioned that the crank pin 54- ivorking inwardly along the slot ll will, aiter the crank arm 53 has nioved the settingmember 16 to a proper engaging` position, reach the oilset and thereupon Will cause a lag;i in `the operation ci the lever 30 and consequently the engagementot the setting member 16 with the work will no longer be continued after the depression of the setting` member 2l has cinnmenced. liter the cranlt pin 5ft has passed the otiset then the roel-ting movement of the lever BO Will be continued and both levers *ivill return the members ot the punch and settingmecha nisms to their initial disengaged positions.

An automatic feed is provided forv the purpose of feeding eyelets lto the spring finger i3 of the setting` mechanism in order that the finger may severally pick up the eyelets as they are fed to it and insert the eyelet picked np in the hole punched in the v-:orlr a'i'ter the unetioninggy of the punch mechanism and preliminary to the action ot the setting' mechanism. To this end an antomatic feeding device ot common type is employed having` a hopper (3G and a 'feed chute G7 leading` from the hopper, and 'from the end ci which chiite the eyelet is picked oli in the usual manner by the springl linge 23 as the chute is reciprocated or oscillated to present he eyelet to the linger. ln order to obtain a `proper reciprocation or oscilhtion oi the chute, it togetherivith the hopper is mounted upon a slidingl carrier G8 arranged alongside the iframe vand occupying an inclined position in relation thereto The carrier has in it a slot @through which errtends a bolt i passed through the :traine and retained by a tightening,` not TO. rThe retention or the bolt is sach that its head will draw against the side ot the carrier and rictionally hold it in any position to which it may be mover nfithin the range permitted by the slot Si'. rThe carrier is otherwise slidably supportedbj,r an upv?ardly-eiztendinp; arm il supported from olii the upper end oi a crank arm 72 on 'the end ot the sha'lit (on which the levers SO, Si are mounted) by a pin Tel extending laterally from 'the arm il and contained Within an inclined slot T in the upper end oi? the crank arm T2. Thus arranged the automatic leed will operate as follows: The normal position of the chute is one in which the end ot the chute is away from the pnnch and setting mechanisms. As the levers and Si are turned ttor moving thenien'ibers ot the punch mechanism into engaging positions the shaft 32 will turn With the lever 3l and thereby through the cranl; arm `72, pin i' and arm 71 move the sliding carrier 65% and 'feeding device with it in a 'forward direction until the month ot the chute 6'( and eyelet therein substantially 'within the path 'of the spring` linger 23 ot the setting mecha-n nism. According to the operation oit the levers 30 and Si previously described their next lmovement is a reverse movement for moving the members of the punchv and setting mechanisms bach to their normal or disengaged positions and afterward movingl the members oi the setting mechanism into theire'ngaging positions. During this first movement or the movement ior returning" the members of' the punch and setting mech anisms to their original disengaged po`sitions the reverse movement of the 'shaft 3Q will not disturb the chute as the pin 74: Will draiv alongl the slot 75 in the cr-ank arm 7 This condition remains until the lever 3l has elevated the finger 23 of the setting mechanism to a position Where it will pick the eyelet oli the end of the chute. The crank arm 72 Will then have been moved to a position Where it will again be in engagement with the pin Tet then located at the tor- Ward end ci the slot 75 in the oranti arm and the then continuingl reverse movement oit the shaft 32, attending the operation of the levers 30 and 3l vfor moving the members ot the settingmechanism into an engaging position, will return the chtite to its normal disengaged position. llore it will remain `until the members ot the punch mechanism are again moved into an engaging,l position, 'for' as the levers tnrn to return the members of the setting mechanism to their disengaged position the ensuing reverse turning' of the shaft 82 will 'cause the crank arm '72 to draw over the pin 74 by reason of the slot 75 in the end or the arm and consequently will not disturb the position oi" the chtite. All parts will then be occupyingl their initial positions preparatory lto the next ensuing` operation of the machina In connection with the operation of the automatic leed it will be further explained that the hopper 66 of the vfeed mechanism is provided inside the hopper with the usual stirrer or brush (not shown) which turns or oscillates on a pin 'Ti' mounted to turn in bearings on the .top and bottom Walls ot the hopper. To` this pin an arm 78 is tixedlv secured and pivotally connectingl with this arm is a linl; 79 loosely mounted on the end of the. bolt laterally extending; 'from the side et the frame. clnding the hopper and chute are reciprocated during the operation of the machine the stirrer or brush inside the hopper will be agitated by the arrangement of the parte thus described.

Thel machine further embodies a clutchorming mechanism having an automatic release whereby only a single complete turn or rotation .is permitted the driving shaft -'when the clutch is throivn'iin, the punchinp of the hole in the Work, application ci? As the feeding` device in i the eyelet to the work and setting of the eyelet being completed during such one complete rotation of the driving shaft.

To this end the driving shaft is provided with a pulley 8O mounted to turn loosely upon it and to which pulley powerl is applied in any suitable manner. The pulley has on its inner side facing the frame an annular ring or flange 8l and projecting laterally from this flange are a number of studs 82. Mounted upon the main shaft 32 alongside the pulley on the side thereof provided with the studs is a hub 84. which is fixed to the shaft. This hub has on one side thereof a hub extension Sil with slot 85 in it. In this slot, pivoted to the hub by a pin 86, is arranged a clutch member 87 extending outwardly from the hub extension in a direction radial to the main shaft and movable into an engaging or disengaging position with relation to the pulley 80 and studs S2 carried by it. lVhen in an engaging position the clutch member will be moved to a position where its side S7 will bear against the annular'flange on the pulley, the body of the clutch member then being interposed or lying within the path of the studs carried by the pulley as the pulley is rotated and consequently may be engaged by any one of said studs as the pulley is turned. From this engaging position the clutch member is movable away from the annular flange on the pulley and out of the path of the studs thereon. It will also beA observed that the clutch member has such extension that the outer end 872 thereof will project beyond the outer face of the annular flange 8l on the pulley, The clutch member is yieldingly maintained in an engaging position by means of a spring S8 fixed to it and to the hub extension Sel on which the clutch member is mounted.

Mounted on a hub 89 arranged to turn upon a stud 90 fixed to the frame in a position beneath the clutch member 87 is an upwardlyextending clutch-controlling arm 92. This arm turns upon an axis parallel with thevaxis of the main shaft 32 and the upper end of the arm, as the arm is pivotally turned, moves in a general direction toward or away from the shaft 32 and thereby into different operative positions with relation to the clutch member 87. The upper end of the arm presents an outwardly turned portion 93 which when the arm is moved inwardly in the direction of the main shaft is adapted to bear against the periphery of the annular flange 8l on the pulley. This portion of the arm having such bearing is provided with an inclined side 94. which, when the end of the arm isbearing against the annular flange on the pulley, lies within the plane of the studs on the pulley and just outside the path described by the studs when the pulley is rotated. The upper end of the ing the frame of the machine and a stop 97.

Attached to the hub 89 on which the clutchcontrolling arm 92 is mounted is a lever 98.

`To the outer end of this lever is secured a spring 99 attached to the frame of the machine, the arrangement being such that the draft of the spring upon the lever will normally hold the arm 92 in its inturned position from which position the arm may be released by draft upon a link connected to the opposing inner arm of the lever 9S, the draft being applied by any suitable means, preferably by a connected foot pedal (not shown).

The operation of the clutch mechanism is as follows: The normal position of the arm 92 is its inturned position with the upper end 93 of the arm bearing against the an* nular flange 8l on the pulley. l/Vhen thus positioned the clutch member will have bearing against the side 9G of the arm resting against the stop 97 and thereby be maintained in a disengaging position with relation to the studs 82 borne by the pulley, and accordingly the pulley when rotated will simply idle upon the shaft 32.

Assuming `now that the clutchecontrolling arm is released outwardly by draft on the link 100, thereupon by the turning of lever 98 the arm 92 moved outwardly will release the clutch member 87 into an engaging position with bearing against the side of the annular flange on the pulley and disposed within the path of the studs S2 as the pulley is rotated. When thus released into an engaging position the face 95 of the arm will bear against the outer end 872 of the clutch member and the arm will thereby be maintained in an outturned position. Immediately upon the clutch member entering the path of the studs 82 on the pulley it will be engaged by some one of the studs and the eupon the pulley will, through the clutch member, turn the main shaft 32. As the shaft is turned the clutch n'iember will be turned away from the clutch-controlli]1g arm 92 and thereupon this arm will resume its normal inturned position. rlhe ro tation of the main shaft will continue until the clutch member has been brought around to a position where the outer projecting end 872 thereof will engage the inclined surface 94 of the clutch-controlling arm. lmmediately on contact with this surface the clutch member will ride thereon and be moved inwardly out of the path of the stud driving it and onto the side 9G of the arm where it will be maintained in a disengaged position resting against the stop S7 on the arm and the pulley then left to idle. The release of the clutch member is commensurate with a single turn or revolution CTX til)
