UNITED STATES JULIUS A. DYBLIE, 0F JULIET, ILLINOIS.

NUTTING-UP MACHINE application inea February is, 1922. serial No. 536,125.

To all whom it allay concern. y

Be it known that I, JULIUs A. DYBLIE, a citizen of the United States, residing at Joliet, in the county of `Will and Statel of Illinois, have invented certain` new and useful Improvements in Nutting-Up Machines, of which the'following is a specification.

This invention relates `to a new and improved nutting-ilp machine and more specifically to a. machine adapted to mechanically juxtapose bolts and nuts and to thread theA nuts upon the bolts. In connection with numerous types of bolts, such,l for example, as track bolts, it is necessary that the bolts be ship d with the nut threaded upon each iough some nutting up machines have been developed, it has been a general practice heretofore to thread these nuts upon the bolts by hand. This is particularly true in connection with hot-forged nuts for the reason that these nuts are subject to considerable irregularity in shape and inthe location of the threaded opening.

In hand work, the nuts are not uniformly placed upon the bolts and frequently, through carelessness, bolts without nuts will pe found in the kegs and such bolts are useeSS.

It is an object of the present invention to provide a machine which will mechanically bring together nuts and bolts and will positivelyaiid uniformly thread the nuts upon the bolts.

It is a further object to provide a machine* of this character which is adapted to handle nuts which are somewhat irregular in size and 'form'.

e It 'is also an object to provide a machine which will positively deliver .the nutted bolts for packing.

lt is an additional object to provide a machine which may be operated at relatively high speed and which will-nut up bolts yin large quantities with a minimum of hand labor.

Other and further objects will appear as.- the description proceeds. Broadly, my invention comprises, in a nutting-up machine, conveying means for nutsv and conveying means for bolts, these two conveying' means having overlapping paths and means adapted to intermittently enter the point of overlap of the two paths to screw the nut upon the bolt.

In its more specific form, the bolt carrying conveyor comprises a fixed rack and a re- -ciprocated rack adapted to give the bolts` a step by step movement in the fixed rack. The nut carrying conveyor comprises a chute and a reciprocating bar adapted to intermittently take anut from the chute and present it adjacent the end of the bolt.

The nut rotating device comprises a recprocating, rotating member which is movedv into and ont `of engagement. with the nut. This member is provided with a Vplunger adapted to enter the opening in the nut to gulls center lthe opening in relation to the I have illustrated a preferred embodiment of my invention in the accompanying drawings. iii which- Figure l is a side elevation of my machine;

Figuref15 is a fragmentary plan view showing the nut arrester, nut socket and as- Referring now to the drawings, the machine comprises the base frame 20 which is" supported at one end by the pair of wheels 2l and at the opposite end by the j pivot wheel 22 and adjustable pins 23. To

- frame by bolts 31 tting in elongate slots 32, thus permitting lateral .adjustment of the upper frame upon the base frame. A plate bolted to the member 30 has its upper edge provided with semi-circular frecesses 33 forming a rack capable of holding bolts in parallel series. A similar plate bolted to the outer member 30 is provided with notches 34` which register with the notches 33. These notches 34, however, as best shown in Figure 8, are deeper than the recesses 33 and are adapted to receive the oval shoulders adjacent the heads of the bolts and to thus prevent the bolts from rotating. The member 30 is also provided with the fixed flange 30a against which the heads of the bolts bear. The right end of the

members

30 and 30 are cut 0E at an angle as shown at 301. Intermediate the two

members

30 and 30 are

members

35 and 35 joined by members 36 to form a movable frame 35a. The members 35 extend parallel to the

members

30 and 30 and are formed with notches 37 therein similar to the notches 33 in the member 30.

Adjacent either end of the movable frame are the

pivots

38 and 39 to which are pivoted the

levers

40 and 41. The lower ends of these levers are pivotallyconnected to bell ycranks 42 and 43, the upper arms of the bell cranks being connected by the rod 44 so that the two bell cranks operate in unison. The bell crank 42 is pivoted upon a short shaft 45 supported in the `

members

30 and 30. The bell crank 43 is keyed to the shaft 46 which. shaft extends transversely of the machine parallel to the main drive shaft 29. To this shaft 46 is keyed an arm 47 shown in Figure 1,'the upper end of which is connected by the adjustable link 48 to an arm 49 which is pivoted to the base frame at 50. This arm 49 bears against the cam 51 carried by the main drive shaft 29.

It will be noted that the weight of the movable frame consisting of members 35 and 36 rests upon the bell cranks and tends to maintain the arm 49 against the cam 51.

The movable frame is further provided with.

a pivot 52 to which is connected the rod 53, the opposite end of which is pivotally connected to the arm 54. This arm 54 is keyed to the shaft 55 which extends trans- ,The

the upper end of which is pivotally connected by link 57 to the arm 58 which latter is pivoted at 59 beside the pivot 50 of the arm 49. This arm 58 bears against the cam 60 which is rotated by main shaft 29. This arm 58 has connected thereto the spring 6l, the opposite end of which is connected at 62 to the upper frame member 63. This spring 61 serves to hold the arm 58 against the cam 60. v

The nut handling portion of the machine comprises the table 64 at one side of which is the trough The bottom of the trough is formed by the upper run of the conveyor belt 66 which belt passes over pulleys 67 and 68. The upper run is suppo-rted by fixed member 69. The pulley is keyed to the shaft of the pulley 68 and this pulley 70 is -connected by the drive belt 71 to the pulley 72 upon the main shaft 29. The sloping chute 73 leads from the delivery end of the trough 65, this chute terminating at 74 in a short, vertical drop.

The nut pusher bar 75 has its end 76 reciprocated to and from a position under the end of the vertical'portion 74 of the chute. The bar 75 is provided with the rear extension 77 which is guided through the block 78. pin 79 connects the extension 77 with the link 80, the latter being connected at 81 to the bell crank lever 82. The connection between the link and the pin 79 is eccentric whereby the position of the bar 75 may be adjusted. This lever 82 is pivoted at 83 to the frame and its lower arm 84 engages a cam 85 carried by the shaft 29.

The rod 86 is pivotally connected to the upper arm of the lever 82 and extends;

rod. This spring serves to maintain thelower arm of the bellcrank 82 in contact with the cam 85.

The bell crank 89 is pivotally supported at 90 upon the frame, and the lower arm of this bell crank is connected by the link 91 to the upper arm of the bell crank 82. The upper arm of the bell `crank 89 carries the -spring pressed plunger 90 which is opposed in direction to the outer end of the nut pusher 75. The nut arrester 92 is carried by the plunger 93 which reciprocates in the guide 94, as best shown in Fi ure 1-2. The opposite end of t'he rod 93 as the yoke 95 secured thereto by means of cap screw 96. The pin 97 is fitted into the yoke and its inner end compresses the spring 98 contained in a bore in the guide ofthe gear wheel 2 v arm 131.

The'nut rotating assembly is best shown in Figure 5 and comprises the hollow shaft` 100,` which is mounted upon the tubular shaft 104 between blocks 101' and 102 which blocks support shaft 104. The hollow shaft.

' shaft 100 but isslidahle therein. The feathers are retained in place by sleeve 104.

Rigidly secured to the inner end of the tubular shaft is nut socket body 105 provided 'with the nut socket' 106. As best shown in Figure 6, this head is provided with a recess 1 07 adapted' to'receive nuts and to cause them to' rotate with the head. The recess is star-shaped rather than square so as to limit the amount of slip before the` head positively engages the nut to degrecs ratherthan 90 degrees.-

As shown in Figure 2, the tubular shaft 104 hasthe fixed spring seat 108 clamped thereto. The s ring 109 is fitted about the of the collar and the slid-` -able sprin seat 110 is fitted upon the shaft shaft to the le ad'acent t e opposite end ofthe spring.

e collar 111 is slidably fitted upon the shaft 104. The thrust bearing assembly 112 is located between the slidable collar 111 and the round nut 113 which latter is held in place upon the outer end of the shaft by the f' jam nut 11.4. The inner face of the sliding collar 111 bears against the thrust bearing aembl 115. This assembly is retained adjacent t vev sliding collar by means of the ring plate 116 which latter is secured to the yoke 117. The' oke v117 is secured b screws 118 to the sli ing collar 111. e .outer U- shapedportion 119 of the oke has the slidplunger 120 connecte thereto by nuts 121 and 122, the connection being such that thI plunger may be adjusted relative tothe o e. y The lunger 120 is supported in bearings 123 and) 124 in the tubular shaft 104 and its inner end has the plunger head 125 slidably secured there This key has i s endI located in slotsf127 in the head. f The head is pressed outwardly relativev to the lunger by means of the spring 128 whic is enclosed b the head. The outer end of the head is slig tly tapered and is provided with the shoulder 129 adapted to bear against the nuts.

The sliding collar 111 is connected byv trunnions 130 to the outer end of therocking This arm 131 is pivoted upon trunnions 132 carried by the sleeve 133 which latter is loosely fitted upon the main shaft 29; This sleeve 133 is retained between the outer fixed sleeve 134 and the central boss ofthe main cam wheel 135. The lower end by means of the key 126.I

of the rocking arm 131 is provided with the cam follower roller 136 adapted to roll upon the outer lateral cam face of the wheel 1135.

The inner end of the rocking arm is connected by the spring 137 to the base frame, this spring serving to maintain the roller 136 against the cam wheel 135.. l

As shown in Figure 1, the cam wheel is provided with a cam surface having a. first lift 138 and a second lift 139 with a short dwell ,between the lifts. The cam gradually rises slightly and then drops ofi', with a single -drop 140. The purpose of this cam formation will appear hereafter.

In the operation of my machine, a seriesA of bolts are placed in the

notches

33 and 34 in theiixed frams. A quantity of nuts are placed in the-:nut trough and'chute. When the shaft 29 is rotated, the cam 51 forces the arm 49 to the right as seen. in Figure 1. This movement to the ri ht is transmitted to link 48 and by arm 4 to the shaft 46. Thebell crank lever 43 is keyed to the shaft 46 and therotation of the shaft 46 serves to rotate the bell crank lever in the clockwise direction as seen in Fi s 1 and 4. Due to theA connection by the ink 44, the bell crank 42 makes an identical movement. The rotation of these bell cranks serves to move upwardly the movable frame 35 and the frame lifts with it the bolts. The bolts are lifted from the, notches 33'` and 34, inthe fixed frame and are carried inthe notches 37 in the movable frame. This movement is suflicient so that the bolts are lifted entirely clear of the notches in the fixed frame.

At this point in the cycle of operation, the cam upon shaft 29 swings the lever 58 to the right and this movement to the rglft is transmitted through link 57 and arm 56 to the shaft 55. Movement of theshaft 55 causes the arm 54 to move from the position. in which it is shown in Figure 4 to that in which itis shown in Figurev 1. This arm is connected by link 53 and pin 52 to the movable frame and this movement moves the movable vframe to the right a distance of one notch to the position in which it is shown in Figure 1.

While the movable frame is held to the right in this manner, the arm 49 is dropped roo from its cam` 51 and the weight of the mcvl able frame and of the bolts carried'thereby serve to move the frame downwardly, thus rotating the bell cranks 42 and 43 in the counterclockwise direction. lVhen the movable frame passes below the level of the fixed frame, the bolts are deposited'in the notches upon the fixed frame; The movable frame drops down to the level in which' position, the arm 58 moves down from the igh point of the cam 60, being held against the cam by the spring 61. This movement of the arm 58 by its connection with the arm 54 serves to swing the movable frame to the left a distance of one notch. This completes the cycle of movement of the frame and as has been explained, such movement of the frame advances all of the bolts a distance of one notch and presents a new 'bolt opposite the nutting-up shaft.

Referring now to the nut presenting means, the nut pusher bar 75, when in its inwardI position, has the lowermost nut of the series in the chute resting upon its outer end 76. This end 76 as shown in Figure 9 is provided with a lip 7 6 adapted to aid in retaining the nut thereon and is further provided with grooves 70a adapted to receive any burrs on the edge of the nuts. As the shaft 29 rotates, the cam 85 lifts, the lower end 84 of the bell crank 82 and the upper end of the bell crank moves to the left as seen in Figure 4, and by means of the link 80, the nut pusherbar is moved to the left.l It carries with it the lowerlnost nut and the remaining column of nuts rests upon the top of the rez-t' portion of the bar. The nut carried by the pusher is moved outwardly to a point oposite the bolt in the last notch in the rack, the paths of the nuts and the bolts thus overlapping at this point,

It will beobserved that the cam which reciprocates the nut arrester 92, shown in Figure 11, is so timed that the arrester is withdrawn just as the pusher bar starts to movey forward. When the pusher bar is later retracted, the nut arrester is advanced as soon as the pusher has cleared its path', and the arrester prevents the lowcrmost nut from falling oil' the end 76 of the pusher as the column of nuts drops ldown upon being cleared by the main body of the pusher ha The bell crank 89 is operatively connected to the bell crank 82and is operated simultaneously therewith. The spring press plunger 90 is brought against the outer face l of the nut carried by the bar as the nut reaches its position in alignment with the bolt. The nut is thus yieldingly retained between the plunger and the pusher bar, nd is supported upon the portion 76 of the ar.

When the nut is positioned in alignment with the bolt by means of the pusher 7 5 and the plunger 90, the cam lfollower roller 136 .rises up the first rise 138 on the main cam surface. This swings outwardly the lower end of the roller arm 131 and causes its upward end to swing inwardly. This in ward movementl is transmitted through trunions 130 to the slidable collar 111. The yoke 117 moves with the collar 111 and the yoke carries with it the plunger 120. This movement vof the plunger 120 serves to carry its head 125 toward the nut and the tapered head enters the opening in the nut and centers the nut on the plunger, the shoulder 129 bringing up against the face of the nut.

At this point in the operation of the machine, the nut pusher and the plunger 90 are withdrawn from contact with the nut which remains supported upon the plunger head 125. Immediately thereafter, the cam follower roller 136 rises upon the second lift 139 of the cam and the upper end of the rocker arm is swung further to the right carrying with it the collar 111'. This further movement of the collar is trans` mitted to the plunger 125 and the plunger is advanced until its face bears against the end of the bolt, the yielding permitted by the spring 128 in the head taking care of any inequality of lengths of bolts.

Further, this second movement of the collar 111 brings the thrust bearing 115 against the spring se'at 110 and moves that seat to the right. Through the spring 109 and'xed spring seat 108, the tubular shaft 104f'jis thrust yieldingly to the right. The nut socket 106 is brought to bear against the nut and as it rotates, the nut slips into the socket and is then rotated with the tubular shaft. This rotation screws the nut upon the bolt.

'In order to keep a uniform pressure upon the nut, the cam surface has a continual slight rise from the lift 139 to the drop-olf 140 so that the tubular shaft is urged forward an amount approximately equal to that which the nut advances as it is threaded upon the bolt.' When the cam follower 136 rolls down the drop-olf portion 140 of the cam, the roller is held in engagement with the cam by the spring 137 and the collar 111 is swung. outwardly. Through its connection by means of yoke 117, the plunger 120 moves outwardly with the collar. The collar also through thrust bearing 112 engages the round nut 113 and moves the tubular shaft 104 outwardly, the movement of the plunger beginning prior to the movement of the shaft.

The operations of the machine are so coordinated that as soon as the nutting-up shaft assembly starts to move to the left and clears the nut, the movable rack 35a lifts the bolts and moves them forward one notch in the manner which has been described. As the movable rack moves downwardly, the bolt which has just been nutted up is carried downwardly at a point beyond the last notch in the fixed rack. yIt engages the sloping surface 30b of members 30 and 30', and when the movable rack moves to the left, the nutted up bolt slides olf these sloping surfaces into a suitable chute 160, shown in Figure 3, which preferabl leads to a keg or similar receptacle or pac ing case.

Should there be no bolt opposite anut and centered and thrust forwar which has been presented by the (push rod bythe plunger head 125, when this head is drawn ack, the nut will be thrust from the head by its engagement with the nut` socket 106 and will drop downwardly. A suitable chute 161, 'shown in Figure 3, may be provided to carry oli any such nuts. n

The bolt holding frame members and 30 may be adjusted laterally upon the base frame so as to render the machine capable of nutting up bolts of different lengths. It is essential only that the threaded end of the boltbe presented in the proper relation to the nutting-up shaft. I have shown one particular embodiment of my invention but this obviously is capable of modification to adapt it for use with varying bolts and nuts and to varying conditions of use. It is my intention to cover all such modifications as come within the spirit and sccpe of the appended claims.
