This invention relates to fasteningforming and inserting machines andLisherein. shown, by way of: illustration, embodiedin a machine for severingand inserting wire. slugs in the bottoms of 5 b'ootsand shoes of the type disclosed in United States'Letters Patent No. 786,190, gra'ntedMarch 28;.1905', on an application filed in the name of Louis Casgrain.

In-machines of the type referred to above it is som'etimestd'sirable to eliminate the usual movement of translation of the wire severing and transferring-member and to utilize in placethereof a rotary movement. There is disclosed in United States Letters Patent No. 1,651,469, granted December 6, 1927 on anapplication filed in the name of William Thomas Buckingham Roberts; a mechanism which alines the wire receiving: passage: inthe-severing andtransferring member witha Wire feeding passage prior to the insure proper 'ali'nement of the passage in said: member with ai wire receiving passage prior tothe severing operation and with-the'path ofmove ment of the driver after the transferring-opera tion has been completed. A'fe'atureof this invention, accordingly, consists in mechanism constructed and arranged to cause relative movement between a; movable die and a stationary die; the mechanism including means for holding the dies positively against 4 movement relatively to 'e'achother prior to the severing operation and to hold the transferring die positively against movement after it has been moved to inserting position. As illustrated,

the machine is provided with a die' carrier arranged for rotati'ontomove adie froma substantially" horizontal fastening receiving position to a substantially vertical fastening-driving position. A link is connected at one-end to-the carrier and a bell cranklever having an arrn connected to the other encl of the link; the link and the arm being arranged'in a straight line when the movable die is infastening receiving position.

7 The machine is' also providedwith a' second link connected to the other" arm of said ball crank leve1e- A second bell crank lever is connected: to

the otherarm of the second link,.said* last-men-- tionedilink and arm being arranged in a straight line when the die carrier is in .driving position. Each of'the bell crank levers is provided with independent means for adjusting the position of the respective bell cranks to insure that the mov-' able die will be properly alined in fastening re; ceiving .position and in driving position.

These and other features of the inventionwill: appear more fully from the'following;detailedwde scription When read in connection with the accompanying drawings and will be pointed out inthe accompanying claims.

In. the illustrated embodiment of the inven-' tion the-mechanism for. severingand transferringxfastenings into'tthepath' of movement of a" 30 driver lU.:(Fig'i 2) isshown as applied to a mar chine' of the type disclosed in United States-Lev ters Patent No. 1,651,469, granted-December 6,: 1927, on an application filed in the name of William Thomas Buckingham Roberts. The pre-- 351 ferred form of mechanism comprises asevering and'transferring member l2 which is arranged to be turned through during, each cycle of operationof the machine to cut off arlength of .wire and to transfer the" severedwire to driving. position; The member I2-is provided with a shearing die l4 and is supported: on the'forward endof. a horizontal sleeve "5' which extends 'rearwardly. The sleeve |6-.is rotatably mounted on' a shaft l8 fixed in the frame of the"- machine. The sleeve l6- 45. has secured to its rear end a'rforked arm 20 provided; with a crank. pin 22.. 'When the" severing and transferringm'ember l=2- is in the position shown'in Fig; 1 to receive the endof the wire to be cutoff (hereinafter called the shearing position) the crank pin 22" is located at the right of the shaft l8 and the axis 'of the sleeve I6 and the pin 22 are substantially in' the: same horizontalplane'z- When the shearing and transferringwmemberi I 2 has been turned; toxtheposition 55;

indicated by dotted lines in Fig. 1 to sever a fastening and to transfer the fastening into the path of movement of the driver It the axis of the crank pin 22 is located directly above the axis of the sleeve [6 and in substantially the 'same vertical plane.

The crank pin 22 forms a pivotal connection between the forked arm 28 and one end of a link 24,

the other 'end of which is pivotally secured to a depending arm 25 of a bell crank lever28. The bell crank lever 28 is pivoted on an eccentric sleeve which is rotatably mountedon a horizontal shaft 32 extending forwardly and rearwardly of the machine and lying directly above the sleeve I 6 of the shearing and transferring device. The link 24 and the arm 26 of the bell crank lever 28 form in effect a toggle which is straightened when the shearing and transferring device I2 is in its shearing position, as shown in Fig. 1. The eccentric sleeve 30 is provided with a laterally "extending. arm 34 having formed therein a curved, slot 36 concentric with the axis of the shaft 32 on which the sleeve 38 is mounted. The eccentric sleeve 30 maybe adjusted about the shaft 32 by rotating the arm 34 when the toggle 24,. 26 is 'insstraightened condition toadjust the position .of the shearing and transferring die [4 relatively to a. co-op'erating' shearing die 38 to alines the wire receiving passages 31 and 39 in the-dies and 38. The arm 34 is clamped in adjusted'iposition by a screw 48 passing through the slot-36 inthe arm 34. and threaded into a member 42 which is held in. a fixed position and is supported at one end on an enlarged portion 44- of the eccentric'sleeve 30. The enlarged portion 44 of theeccentric sleeve 30 is concentric with the shaft 32 solthat rotation of the eccentric sleeve 30 does not cause displacement of the member .2 1

.I A second arm 46 of-the bell crank lever 28 is pivoted 'toxa link 48 the other .end of which is pivotally connected to an arm 58 of a bellcrank lever 52; "The bell crank lever 52 'is pivoted on an eccentric portion 54 of a shaft 56 which. is rotatably mounted in a bracket 58.secured to the machine frame by a-screw 59. The shaft 56 which serves to support the other end of the mem-v ber 42' is positioned to the right of the shaft 32 on which the eccentric sleeve 30 is mounted and its axis'is in substantially the same horizontal plane as the axis of the shaft'32; The arm 50 on thebell crank lever 52 and the link 48 form in effect a second toggle 'which is in'strai'ghtened' position,"as shown in its dotted line position in Fig;-1, when the shearing and transferring de-' vice 12' is in fastening inserting position. The shaft.56"is provided with a laterally extending arm 60 by which the shaft 56 and the eccentric 54'may be rotated. "By adjusting the eccentric 54 'whenthe toggle '48, 50 1s in the straightened position mentioned above, the shearing and transferring device l2 may be adjusted about the axis of the: shaft l6 relatively to the path of move-' ment of the driver ID. The arm 681s provided with an arcuate 'slot:62 which is concentric to the axis of the shaft56 through which passes a screw 64 threaded into the bracket 58 to clamp the arm 60 .and th'eeccentric 54 in fixed position. A second arm-66 of" the bell crank lever 52 .extends upwardly and is'pivotally connected to one nd 'ofa link 68 which extends to the left and which at-itsother end is pivotally connected to the lower end of a cam lever 10. The cam lever 10 is'p'ivoted to a horizontal shaftl2 extending for:-

waidlyandrearivardly of the machine whichis secured in a bracket 74 to the machine by a threaded stud 15. The cam lever 10 carries a cam roll 16 which enters a cam groove, the center line 17 of which is shown by. a dot and dash line in Fig. 1, in the rear face of a cam 18 secured to the drive shaft 80 of the machine. 18 operates the shearing and transferring device i l-through the mechanism above described.

The shearing and transferring device I2 is actu- "ated solely by levers and links including the two toggles referred to above, one toggle comprising the arm 26 and the link 24 which is in straightened condition when the shearing and transferring device I2 is in shearing position. The other toggle comprises thelink 48 and the arm of the bell crank lever 52 which is in straightened condition' when theshearing device I2 is in fastenin Fig. 1. During the first portion of the move ment of the. shearing and transferring device l2 the wire is severed and duringthe remainder of the portion of the movement of'the device I2 the severed fastening is moved into driving position. The passage 31 in fastening receiving position having been properly alined with the passage 39 by means of the eccentricadjusting themechanism 30 described above and the position of the passage 31 having also been adjusted through the eccentric mechanism on which the bell crank lever 52.,is mounted, the passage 37 will be properly alined in both its fastening receiving position and fastening driving. position. The position of the device l2 cannot be changed in either fastening re-,

ceiving' or fastening inserting position because of the; straightened condition of one of the pairs of toggles in each of thejabove positions. The

device 12, therefore, is held positively against,

movement when the wire-is beingfed into the device, 12 and the device is also positively held against movement when a fastening, is being driven. Furthermore, the device I2 is readily adjustable about itsaxisin either position by means of the eccentric sleeve v3!! and the eccentric shaft 54. ,1
