chines, of which the following is a specification.

This invention relates in general to bail I end forming machines and has more particular reference to the formation of ball ends I of the general character illustrated and described in the (Io-pending application of James :H. Doyle and n self filed-August 18, 1917, Serial No. 186,8 3.

A principal object of my invention is the provision of a bail end forming machine for forming up the endsofthe bails-.correctly and accuratelyand consisting of strong and simple parts arranged-to require-little power and unlikely to require frequent or costly'repair or replacement. 7 V I A still further object of the-invention 'is the provision of a machine which-will operateat high speed and which will require merely the services of. an unskilled attend- 7 Other objects and advantages of; the invention: will be apparent as it is better understood-from {the following descriptionwhen considered in connection with the accompanying drawing ,illustrati'nga preferred embodiment thereof.

I The embodiment of the invention shownon the drawingis particularly designed to: produce a bail with the ends formed as shown in F ig. 10, which is substantially the ball of the co-pending application to which reference has been 1nade. Viewing this figure itwill be noted that the ends of the bail 22 are looped at 23 and 24, one loop 23 being disposed substantiallyjin the plane of the .body and the other end 24; at right angles thereto. Theterminal ends 25 and 26 are bent at right angles tothe planes ofthe loops so that 'one end25. is disposed at right angles to the plane of the body of: the bail and the other end 26 in this plane. f It is intended that when the bail is assembled, both loops will bedisposed in;

the plane of the body, and this is attained by bending the loop '24 at right angles about the point 27 of its connection with the body of the bail.

A machine illustrating i an embodiment. of. V

the invention and shown on the drawings is adapted to operate upon the bails after the body of thebail has been given itsdesired curvature and the ends brought to extend in the samegeneral direction. This machine COIIlPI'lSGS 'EL bed 31mounted upon any suitable framework 32 and having a pair of guide recesses 34-Wl 1lOhCaIi'y tl1e horizontal reciprocating forming dies to be later described." Extendingup from the bed ateach side is a bearing bracket or upright 35 in which ismounted a driving shaft 36 anda cam shaft 37. A'pulley 38 and a'pinion i 39 are mounted upon the driving shaft 36, Fig. 8 is'a section taken substantially" on the pinion engaging. a gear 41011 the shaft 3-7. The front of the bedis'cut away at 1 at: the sides or each recess" 34 and thehori? l bail is'positioned and 'thearms 46 closed zontally movable 'dies are reciprocated between the bars 44. It will be understood that the variousdies and forming members and their associated actuating instrumentalities are all timed by cams on the cam shaft to operate in synchronism upon the ends of the incompleted bail thus positioned. The bail is thrust across the two guide bars 44 which are preferably flush with the top of the bed and beneath a holding yoke 45, having two laterally extending arms 46, and

carried upon the end' of a lever 47 which is fulcrumed at 48 onthe bed and carries at its rear end a roller 49 whichengages a I central cam 51 on the cam shaft. This holding lever is the first operativepart of the machine to come into action aftera down on the ends of the bail pinning them to the table as maybe seen by viewing Fig. 1.

Two operations in the present instance are performed on each bail end. Viewing Fig.

1, the end at-the left is first given a loop in a horizontal plane and the extremity then bent up at right angles thereto. This loop is the loop 23 andit is formed by the con- 'joint action of two loop forming dies" 52 and 5 3,'these dies being shown in enlargeddetail in Figs. 16 and 18. Theyeachfconsist of a block of hard metal having slots 54 in either side for engagement with the guide bars 44 between which they reciprocate toward and from each'other under the action of the cams.

The block 52 is actuated by a cam lever 55 pivoted at 56 upon the table and having one end 57 engaging in a recess 58 in the block and the other end provided with'a roller 59 taking into a cam groove 61 of cam part 62 on the cam shaft. A similar arrangement is provided to actuate the block 53. Lever 63 is pivotedat 64 upon the table I ends 57 and 66 toward each other.

. on the block 53. A groove 74 is provided in the recess 72 and intothis groove the wire and has an end 66 engaging in a. recess 67 of block 53 and the other end 68 engaging in cam groove 69 of cam part 71. 'It' will be noted by'viewingFig. 1- that cam grooves 61 and 69 are so constructed that when the cam shaft is rotated from the-operator the levers cal extending recess 72 in its operativeface.

into which fits a male partor projection 73 of the bail is pushed to form the loop bythe 5 projection 7 3. Theblock 53 carries a pin pin will-be later explained. r

i v.At the'same time that the 75 adapted to enter into an appropriate re* cess7 6 in the block 52', the purpose of which loop 23 is being formedin the horizontal plane, the loop 24 at'the other end of the bail is being-formed in a vertical plane and this. isaccomplished by a bending member 77 which is disposed above the end of the bail when it is inserted. This bending member is perhaps best shown in Fig. 21 and in its action cooperates with one.v of two. horizontal reciprocating dies adapted to operate upon this end of the bail. This die in the present instance is numbered 78 and is illustrated in enlarged view in Fig.

19. Like the-diesl52 and 53 it is provided with slotted ways 79 for engagement in the righthand guide bars 44. "WhenSin position the wire extends acrossthe forward parts 81 and 82 of the member 79, said forward parts 81 and 82 providing a recess 83 between them. The adjacentfaces of the parts 81 and 8.2are' provided with slots -'84 p 7' 7' to receive the sides ofthe loop under the action of the bending member 77. This member has an operative shoulder 85 adapted to move down between the parts'81 and 82 to give the loop bend to this end of the bail. Vertical. reciprocation is imparted to the bending member 77 by a lever 86-,having one end 87 engagingin the member 77, the other end carrying a roller 88 -engagingQin' a cam groove 89 of cam part 9 1, it being understood that the bending member 7 7 slides in 'ways' 92 in'the'frame of themachine.

' Just priortoZthe-action of the" bending 7 *member 77 the die78 is advanced to accu- J rately positionthe wire and this is accomplished by a--'l'ever- 93pivoted at '94 on'the v bed and having anend 95 engaging in a slotor recess 96' of the die. The other end of the'lever carries a roller 97 engaging incam slot98 of cam part 99.

As soon as the two loops have been 'formed, the'--two extreme ends of thebail are bent at right angles to the planes oftheir respective loops. 7 v treme' end ofthe bail at the left of-Fig. 1

That is may, the exi is bent up andthe end' of the bail at the right down into a horizontal planerforming the ends 25 and 26. The end 25 is bent up 'by' a bending die,indicated at 101-, which reciprocates in ways 102 in the frame; This die is pushed up from beneath by a lever 103 pivoted at 104- in the arm 105 extending down beneath the bed and having one end 106 engaged in a slot 107 of the'bending member and the other end provided with a roller 108 mounted in cam'slot 109. of cam part 111-; An enlarged view of this bending member 101 isshownin Fig. 17iniwhich it will be noted thatthe forwardcorner ofi this member is given a'recess 112 to. fit-Zthe wire. This -member comes up from-below after theloophas been formed and bends up-the end as may be observed by comparing Figs. 4 and 5, the pin-75 prevents the body of'the'loopfrom. bending or distortion in this step of, the'-operation. .Atsubstantially the same time the end 26 is formed by the die 78 and its companion 113.1also slidable in guideways 14, the die 113 is shown enlarged in Fig. 20 from which it will be noted that it also .is provided with slots 114 for engagement with the guide bars 44. The die 78 is recessed at 115 back of the position of the loop and the upper surface of the recess is provided with a bail end receiving depression1161 The die 113 carries a nose 117 adapted to slide over the projection 82 and into the recess 115 bending down the end 26 as may be seen by comparing Figs. 4 and 5. Dle 113 receives its movement from lever 118 pivoted at 119 on the lpled andhaving an arm 121 engaging in the 1e. a roller 123 taking into cam slot 124 of cam part 125.

The cams are so timed that these operations occur in quick succession and after they are completed the holding armsare elevated to permit, the finished bail to be removed and another inserted.

It is thought that the invention and many of its attendant advantages will be under stood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or,

sacrificing most of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
