To all whom t may concern.'

Be it known that I, PATRICK J. HORGAN, a citizen of the United States, residing at Bevlfassachusetts, have invented certain Improvements in Fastener-Setting l/lachines, of which the following description, in connection with the accompanying drawings, is a specication, like reference characters on the drawings indicating like parts in the several figures. Y

This invention relates to fastener setting machines and, in some of its aspects, it isl particularly concerned with machines for setting compound or two-part fasteners such' cation of J. F. Davey, and embodies coperating sets arranged in vertical alinement,w-ith the upper set stationary andthe lower 4setcapable of movement toward and away from the upper set. rl"he fasteners are supplied to the lower set by means of a movable race way which is oscillated into and out of alinement with the lower set. in certain cases, however, it becomes desirable to delivera fastener to the upper set, as when a raceway delivering fasteners to the lower set would interfere with the work and as, in the illustrative case, when it is desired to use the machine for setting compound or two-'part` fasteners so that one part of ther-z. must be delivered to the lower set and the other part of the fastener to the upper set for cooperating engagement with the two sides of the work.

.ein Obj ect of the invention is to provide imf proved means for delivering fasteners from a raceway to a stationary upper set.

An important feature of the invention relates to the manner in which the spindle of the upper set andthe raceway cooperate to deliver fasteners successively to the set.

Other features of the invention Vrelate to the operating mechanism for the lowerset andthe raceway operating mechanism. erly, in the county ofV Essex and State of These and other' features of the invention will be best understood by considering the particular machine designed `for setting gromets and washers which is' described in the following specification and shown in the accompanying drawings, inwhichr- Figure 1 is a side elevation of the machine with parts in section;

Fig. 2 is an angular view of thecoperating sets and the ends of the two raceways;

Figs. 3, 4, 5 and 6 are transverse sections of the sets showing their relation in various rpositions and the relation of the raceways thereto,

A frame l() has journaled therein a driving shaft l2 which will be provided with any suitable driving or controlling mechanism, not shown herein, and preferably including a single-revolution clutch. The forward portion of the frame will preferably be recessed at 14 for the reception of work and above this recess there is mounted in fixed position an upper set 16 which may be re tained in the frameby means of a clamping bolt 18 which preferably engages a notch in the set. Slidably mounted within this set is a spindle 20 adapted to be normally urged downwardly as, for example, by means of a spring 22. Yieldable spindles of the sort thus far described are well known in the art and are commonly adapted to thread an annular fastener and frictionally to retain the same in position adjacent to the set. In order, however, for a fastener to be positioned upon the spindle, it is necessary that the spindle and the associated raceway shall at some time be in intersecting relation, but when theraceway is advancing to carry the leading fastener into alinement with the spindle some provision is necessary to prevent inteference between the spindle and the fastener. Accordingly for the purposes of the present invention the upperv end of the spindle is preferably provided with a head 23 which limits the downward movement of the spindle, and this headl has anoverhanging crown 24 for engagement with one arm of a pivoted latch 26 which is normally held toward the line of the spindle byA means of a spring 28. When the spindle is retracted. as illustrated in Fig. 5, the latch underlies the rim Patented Aufl'. 30, 1921.

of the crown, and the spindle is thus locked in retracted position. Fasteners are supplied to the upper set 16 from a curved raceway 30 pivotallyV mounted at 32 upon the frame and carrying at its upper end a hopper 34 of any suitable form. Preferably, these parts will be so designed that their center of gravity is approximately at the pivot point in o rder to reduce their inertia and lessen the vibration of the machine. The lower end of this raceway will be provided with the usual retaining spring and the raceway is so designed that the lowormost fastener therein may be brought into alinement with the set 16 and the spindle 20 by the pivotal movement of the raceway. ln order to prevent interference between the raceway and the spindle 20, the spindle is retained in retracted position by means of the latch 26 until the lower end of the raceway has moved into alinement with the spindle 20. rEhe spindle is then released for downward movement by engagement of the latch 26 with a roller 36 upon the raceway 30. The relative position of the parts just before the spindle is released is shown in Fig. 6. lt is intended that the upper raceway in the particular embodiment ofthe invention herein illustrated shall be used for gromets and it will be noted that the design of the raceway is such that these gromets are delivered from the hopper with their barrels up and are` reversed dur ing movement of the-'raceway so that they may be applied flange up to the upper surface of the work. Y

The lower set 40 is resiliently supported upon a stiff spring` 42 in a slide 44 guided in thev frame 10 for vertical movement in alinement with the upper set. Upward Inovement ofthe lower set 40 with relation to said slide 44 is limited by means of a bolt 46. Surrounding the lower set 40 and adapted to assist in centering a washer with relation to the said set and its centrally projecting portion is a. sleeve 4S pressed outwardly by means of a spring (see and'limited in its movement by means of a pin and slot connection 52 with the set 46. The side of this sleeve toward the raccway is beveled in order gradually to release the for upward movement after the washer has been This device shown and claimef in Letters Patent of the United States No. 1,231,210, granted June 26. i917, upon. an application of lllaltcr Sha. t

Beciprocation of the lower set is effected by means of a lever 6() pivoted upon the main shaft 12 and connected by means of a slotted end to a cross pin 62 in a slot of the slide 44.

Actuation of this lever is eected by power conveyed from the main shaft 12 through an eccentric 64 and a linlr 66 to a lever 68 which is pivoted at upon the frame ofthe machine. to the lever 60 by means of a toggle link 72 thus forming a very powerful and effectual arrangement for transforming the rotary motion of the shaft 12 into the reciprocating motion of the slide 44.

Fasteners, in this case annular washers, are supplied to` the lower set 40 from a raceway i' 4 which is practically straight throughout its entire length and is supplied with washers by a hopper 76 of usual form carried at its upper end. The upper end of the raceway 74 is supported by means of a sliding 'l`slot connection to a member 78 which is pivotally mounted upon a rearward extension of the lever 68. The forward end of the raceway is pivotally supported upon a link or lever 80 pivotally attached at 82 to the frame of the machine. Actuation of this raceway to deliver washers to the lower set is effected by means of a pin 84 carried by the lever 60 soV as to coact with a cam slot 86 in the lever 80. It will be noted that the construction and arrangement of the parts for supporting and actuating the race way 7 4 is such that when the forward end of the raceway is moved into alinement with the lower set to deliver a washer thereto, the rear end of the raceway is depressed so that the raceway assumes a more nearly horizontal position and the fastener is delivered to the lower set at a relatively high level. lVhen the raceway is retracted so that it is out of delivering position, the rear end of the raceway is elevated, thereby facilitating the flow of washers along the raceway and depressing the delivery end yof the latter so as to clear the work. A feature of utilizing the lever 68 to support the rear part of the raceway is that it synchronizes the up and down movements ofthe delivery end with those ol the lower tool 40 and insures that the delivery end and the tool will move in opposite directions relatively to each other. The upper or gromet raceway 30 is actuated in suitable timed relation to the other parts of the machine by means of a lever 8S pivotally mounted at 90 upon the frame of the machine and pivotally connected at its upper end to said raeeway. The actuation of this lever is effected in a similar manner to that of the lever 80 by means of a pin and cam slot connection with the lever 60. f y

The machine is preferably controlled so that in its stop position lthe parts will assume the relation illustrated in Figs. l, 2 and 3. It will be noted that a washer has One arm of this lever 68 is connected llO been delivered to the lower set and the washer raceway 74 has been retracted out of alinement with said set. The gromet raceway 30, on the other hand, supports the leading gromet in alinement with the upper set and the spindle 20 is threading the gromet as shown best by Fig. 3. Rotation of the shaft will first cause the' retractiony tion upon the lower set 40 will have lifted.

the spindle 2O so that the crown 24 upon the head of the spindle will be caught by the latch 26, as shown in Fig. 5. s the cycle continues the lower set will go down to its lowest position, the washer raceway will carry a new washer into alinement with the lower set, thev latter will rise to take the new washer, and the washer raceway will move back to the position illustrated in Fig.

l. At approximately the same time the upper raceway will be brought into alinement with the` spindle 2O and, as illustrated fin Fig. 6, will release the spindle 2O to thread the lowermost gromet in said raceway by reason of the contact of the roller 36 with the latch 26. rl`he machine will now be ready for a repetition of its.cycle upon the release of the one-revolution clutch by the operator.
