They are selected by the reciprocating part 17 and moved along the straight. portion 18 of the pathway B from which they are transferred to the straight portion 19 of the same as the operation of the mechanism for feeding the stud members from the chute 11 to'the spreadable part 4, it, will suiiice There- ,ism" for feeding the stud members 1 as shownin Figs. 2 and 3. The stud-feeding Ymechanism includes a base-plate '22 into which is cut the pathway B along which the studmembe'rs are moved.

pressed finger 21 is supported a groove 2-3cut into the base plate, as shown in Figs.

2 and3',fan'd the end ofthe chute 11 isalso secured to the base plate adjacent 'to the pathway as illustrated. The reciprocating part 17 may be mounted upon the plate 22 for" reciprocation above the pathway B in any suitable manner. However, I have shown; in Figurel, a pair of guide members 24 and 25 secured to'the plate 22' and holding and guiding the reciprocating member 17. In Figure 1, I have alsoshown a cam 26 mounted on a shaft 27 adapted to be rotated by suitable means (not shown). 'Ihe cam bears against a roller, 28' located at one end of the reciprocating part 17. This roller is held in contact with the "cam'by means of the spring 29' acting to pull the reciprocating part 17 toward the cam. The

' feeding end of the reciprocating part/17 is out i away beneath the upper surface, as

eshownin Figs. 2 and 3, to provide the shoulders-:30 and 31ffor contact with the stud members 1 to move them forward. I have also shown, in Figs. Lthrough 3,'the

reciprocating part 17 as having a curved end portion which provides a cam surface 32 along one edge against which the pin 33 carried a the spring-pressed finger: 21

' stud-feeding mechanism 'is as follows :-As-

' made one complete reciprocation, a stud member 1 will be positionedin the straight portion 1910f the 'pathway B, having been part 17 is moved forwardly-,the cam surface 32, (shown in dotted lines, Figs. 2. and

13,-)" will act upon the pin 33 to return the spring-pressed finger 21 toa position beyond the edge of the straight portion 18 of the pathway B, as shown in Fig.2. 1

The selectmg and feeding operation of the suminggthat the reciprocating-"part 17 has The springtion 18 of the pathway B as indicated in Fig. 3. As thereciprocating part 17 moved toward the fastener-attaching means by the cam 26, the shoulder 30, will engage the studl in the straight portion 19 of the pathway B and the shoulder 31 will engage the stud 1 in the straight portion "19 of the pathway B andboth studs will be, moved forwardly to the positions shown in Fig.2. The stud member in the straight portion 19 of the pathway B is movedupon the s read; able part 4: during this forward movement of thelpart 17. Also, during this movement of the part 17 the cam surface 32 of the reciprocating part 17 engages the pin33 and moves the spring-pressed finger 21-to the position shown in Fig. 2, so that the stud member 1 in the straight portion 18 of the pathway B may be 'positionediopposite the v end'of the finger 21. The straight edge 34:

of the reciprocating part ,17fcontacts with.

the stud-member located'at' the end of the chute .11 and prevents-it from enterin the pathway B during the entire stroke of the reciprocating part17. The fastener-setting."

means'is operated to dispose of thes-tud spring-pressed finger 21 moves the stud part 1 through the 'connecting'portion '20 of the anernber 1 located upon'the' part 4, and the I pathway B to the straight portion 19'and i another stud member mayenter the pathway B from the end of thechute 11, as shown in.

Fig. 3. By this arrangement and operation tr. parts, I shorten the length of the stroke of the reciprocating part 17 p by one-half the distance between the end ofthe chute 11 and the recess 51in the part4. After the feeding mechanism is once operated, a: stud member 1is delivered to the part 4 at each reciprocationofthe part 17, so long .1 as there are fastener parts injthe' 'chute. It should be understood that thelength of the stroke may be reduced even more" than I have shown:-

and described by'providing more shoulders corresponding with the shoulders 30 and 31 and more offset'jstraight portions corresponding with the'offset straight portions" 18 and" 19-10f the pathway For instance, instead may bear, Thus, when the recipro'catin'g of requiring two reciprocations to feed the stud member from the end of the chute 11 part 17." It should, of course,'be understood that the length of the cam 26 will be reduced to correspond with the desired' length of travel'of the reciprocating part 17. a

A second cam 26? (Fig.1) mounted upon lull the shaft 27 contactslwith the roller'28 secured to theend' of the reciprocating part 12 images? Q I sothat the means feedingthe-rivet parts 7 of'the fastener may-be operated at the] same time and in'conjunction with means for feeding the stud elements.- -Theref0re,' When ever .a stud member is p'lacedupohthe part 4:, a rivet part will'also be placed upon the die member 9,' in substantiallythe same manner-as above described in connection withthe stud-feeding mechanism. 7

I For thefpurpose v of reference merely, I have supplied the. parts 'ofthe rivet-feeding mechanism with numerals corresponding to, the numerals of like parts of the stud-feed:

ing mechanism. These numerals are distingnished by addingtthe letter-a, except,
