Specification of Letters Patent.

Patented March 9, 1909.

To all whom it may concern:

Be it known that l, Jenn V. @ULLINEY, a citizen of the United States, and a resident of Lebanon, in the county of Lebanon, State of Pennsylvania, have invented certain new and useful Improvements in Nutting Machines, of which the following is a specification.

My invention relates to an improved nutting machine adapted more particularly for mechanically applying nuts to comparatively large-size bolts of varying lengths and diameters, and it consists in certain novel features and combinations of cooperating parts as hereafter fully described in connection with the accompanying drawing and specifically pointed out in the claims.

Figure 1 is a sectional elevation of a machine emb'odying my complete invention, taken on the line 11 of Fi 3 and looking in the direction of arrow 1. ig. 2 is a rightside elevation of the same. Fig. 3 is a crosssectional elevation taken on the line 33 of Fig. 1. Fig. 4 is a plan view, the hopper mechanism being cut away. Fig. 5 is an end view of the cam-operated mechanism for effecting the axial movement of the hutting shaft. Fig. 6 is a sectional plan view of the hopper and nut agitator. Fig. 7 is a cross sectional view of the bolt carrying drum, showing certain of the carrier-devices applied thereto and the adjacent portion of the nut chute. Fig. 8 is a similar view to Fig. 7 indicatingamodified construction.

The complete machine, as shown, coinprises an intermittently rotated drum adapt ed for carryin varyin sizes of bolts, a nut hopper with c ute an agitator mechanism all adjustably positioned to suit any particular length of bolts to be operated upon,

and a nutting shaft with endwise movement for turning the bolts into the nuts, all cooperatively arranged in connection with minor features of construction as hereafter fully described; 4

The bolt drum 1 is fixed to a drum shaft 2 mounted in the frame housings 3, 4, 5 parallel with the drive shaft 6, by which latter it is turned, as indicated, one-eighth of a revolution for each rotation of the driveshaft; this intermittent movement being effected by meansof a crank disk 7 on the drive shaft which engages an eight-armed spider 9 on the drum shaft. The drum 1 is provided with a series of longitudinal slideo erations.

11 rearwar ways It) in which are adjustably secured a circular series of carrying devices ll which ceiperate with a corresponding series of fixed carrier arms 12 on the head of the drum to pro erly support the bolts B placed therein by t e operator. To insure proper placing of the boltsin the carrying means on the drum, I employ a fixed guide plate 15, (Figs. 3 and 4) located in front of the retracted nutting shaft head hereafter referred to, and against which the head of each bolt is positioned in placing it upon the drum; and as each bolt is carried to nutting position it is passed under a laterally yielding ,ivoted guard or clamp 16 which securely olds it in properly seated position in the carrying means during the nutting operation but which is capable of moving laterally with the bolt when'the drum is turned, so as to easily free the bolt and then return laterally to its normal position as hereafter referred to. To accurately fix tliedrum in osition for each successive nutting action, rovide a locking disk 20 on the drum shat, having V-shaped peripheral notches corresponding with the different nutting positions of the drum, in connection with a spring-pressed locking in 21 sliding in a guide 22 so that its Wed e-sllaped end is normally seated in each note during the nutting periods.

The nuts are stored in a hopper 25 having a chute 26 through which they are fed to the means for holding them during the nutting As shown the lower end of the cute is open and is so set as to register successively with each of the circumferentiall spaced nutholding pockets 27 forme res ectively in the carrying devices d of the bolt supporting pocket 28 of the latter; so that a nut will be delivered to each of said carrier pockets 27 in axial alinement with an adjacently carried bolt.

Excepting when one or other of these ockets 27 is turned into register with the 0 per chute, the open end of the latter is close so as to retain the nuts therein, by the circumferential plates 29 of the carrier devices 11, which plates, as shown, abut one against another so as to form a chute-closure band around the drum formed with the circumferentially spaced bolt and nut pockets.

To provide for setting the nut hopper and its chute to correspond with the adjusted position of the carrier devices 11 onthe drum, the rigid hopper-carrying arms 30, 3] are tabl arranged to slide on guide-rods 32 fixed between frame brackets 33, 34, so that the hop or may be readily set to proper position for elivering the nuts from t e chute to the successive carrier ockets 27.

In order that -t e nuts may be properly fed from the hopper to the chute it is necessary that an agitator be employed to prevent any blocking of the chute entrance, and to pro erly present the nuts thereto; and that suc agitator mechanism be operative in all ositions to which the hopper may be ad usted. The bottom opemng of the hopper is rectan ular in form and is provided with changeab e nut-supporting fingers 41 and 42 projecting toward each other from opposite wal s and formin jointly an inclined way in line with the inchned wall 43 of the hopper and leading to the lateral chute inlet 44. These fingers are sligthly wider than the thickness of the nuts to be handled, and their projected ends are separated for the passage of an agitator lunger of Hl-shaped cross-section, the side- p ates 50, 50 of which loosely fill the spaces between the fingers and the side walls of the hopper opening, while the cross-bar 51 passes etween the se arated finger ends. The top surface 52 of t 's cross-bar is inclined to correspond with the incline of the fingers, and the two side plates 50 extend unequal distances above 1t, so that the constant up and down movement of the agitator in the chute opening operates upon the stored nuts to turn them until they are chut eci rocating vertical movement is imparted to t e agitator through a connectin'g rod 55 to a crank disk 56 on theend'of an agitator shaft 57 (Fig. 4); said shaft being mounted at the crank-disk end in a sliding bracket 58 (Fig. 1) adjustable on the guide bars 32 to correspond with the adjustment of the hopper, and being slidable axially in the housings 4 and 5 as indicated, with its feathered drive-gear 59 locked by a set screw after proper adjustment has been made.

The nutting shaft 70, mounted in the housin s 4, 5, and havin a chucking head 71 for engagin the bolt, is rotated, as shown, by a gear w eel 72 fixed to a sleeve 73 rotamounted on the drum shaft 2 between the ousings 4 and 5; said sleeve having a ear wheel 74 in mesh with a gear 75 on the riving shaft 6. The pinion 76 on the nutting shaft, which meshes with the sleeve gear 72, is frictionally held, as. shown, between collars 77 and 78 fixed to said shaft, so as to serve as a safet device by slipping upon the shaft in case the normal rotating action of the nutting shaft is interfered with, for. instance, by the accidental placing of a defective bolt or nut. ed to be moved axially, for the purpose of pressing each bolt into screwing engagement with its nut, against the tension of a returnpro igrly passed in succession to, the e. I

And said shaft is also adapting it to the rear of t e machine.

ing spring 79. This forward movement of the nutting shaft is efiected, as shown, by

the action of a spring-tension cam mechanism comprisin a cam wheel 80 on the end of the drive sha t, which acts upon a rollered arm 81 of a shaft 82 having a second arm 83, thejend 84 of which latter ispressed against the end of the nutting shaft 70. This pressin action, as shown, is effected through a suitable interposed spring 86 which is adapted to simply yield to the action of the cam wheel 80 1n case the forward movement of the nutting shaft is prevented,fas for instance by the accidental placing of an unthreaded bolt or nut.

- As shown, the rotation of the agitator shaft 57 is effected by a gear wheel on the rota sleeve 73 of the drum shaft, said gear whee 85 meshing with a gear wheel 90 (Fig. 4) on an interposed idler shaft 91 having a second gear 92 meshing with the feathered gear 59 on the agitator shaft. To

revent breakage in case of the possible locking of the nut a itator, the gear wheel 90 is shown frictiona y secured to the idler shaft 91 between friction collars 93 and 94 on the latter, the degree of friction being regulated by a clam in nut 95 u on a screwthreaded sleeve 96 e to said s aft.

To adapt the hopper mechanism to different sizes of nuts, corresponding sizes of chutes, nut agitators, and of inclined fingers 41 and 42 may be interchan eably applied, and the other manipulating devices may be changed also as required, the operation of the machine in each case being the same.

The nuts in the hopper 25 are successively passed to the chute 26 by the agitator mechanism so as to be delivered uniformly into the nut-holder pocket 27 with the threaded opening in alinement with the nutting shaft 70. T e bolts B are placed longitudinally u on the drum and successively carried,by t e intermittent rotation of the latter, into alinement with the nutting shaft; the 1proper position of the bolt head eing fixed the guide plate 15, and its screw-threade end eing supported in the bearing or ocket.28 of the properly adjusted carrier evice' 11, while the bolt-clamp 16 presses it firmly upon said carrier bearin 28, and the fixed carrier arm 12 when the bolt is brought into alinement with the nutting shaft and with the nut in pocket 27; thereby retaining it in such alinement when it is enga ed and operated by said shaft. While hel in this position the rotary nutting shaft is advanced and quickly screws it into the nut held inpook'et 27, after which the shaft is retracted and the drum rotated to bring another bolt into nutting position; this further rotation of the drum at the same time car ing the nutted bolt past the clamp 16, whic is made yielding so as to insure its assage, and discharg- In case 26 as indicatedin the mod construction bolts an unthreaded or defective bolts or nuts are inadvertently placed in the machine, its operation is continued without damage or interference with the proper timing of the cooperating parts, owing to. the frictional rotation of the agitator and nutting shafts. and the sprin tensioned axial movement of the latter, t e defective piece being simply discharged in each case without affecting the nutting operation.

The: preferred construction above specifically described may obviously be varied in many respects without departing from .the main. features of my invention. For instance,- the nut holder or pocket 27, instead of being formed integral with the adjustable bolt-carrier device 11 on the drum as shown, may be attached to or made art of the chute ed arrangement indicated in Fig. 8, where a chute is shown having its lower end closed to fornna nutholding pocket 27 having a lateral outlet 27 through which the nut is discharged with the boltafter the nutting operation, by the further rotation of the drum; said pocket receiving the nuts in succession from the chute and holdin the samein axial alinement with the bolts and nutting shaft 70, and each bolt being successively carried in front of the pocket and pushed into screwing engagement with its nut by the axial movement of the nutting shaft as in the preferred previously described.
