NAIL DISTRIBUTOR Orgnal- Filed March 14, 1927 2 Sheets-Sheet 2 Patented Mar. ll, 1932 UNITED STATES PATENT OFFICE JOI-IN F. STANDISH, OF WINTHROIl MASSACHUSETTS, ASSIGNOR TO 'UNITED SHOE MA- CHINERY CORPORATION, JERSEY OF PAT'ERSON, NEW JERSEY, A CORPORATION OF` NEW NAIL DISTRIBUTOR Original application filed March 14, 1927, Serialv No. 175,251. Divided and this application filed February 10, 1930. Serial No. 427,253,

The present invention is concerned With distributing apparatus byV which nails or similar fastenings are taken from a source, as a mass held in a receptacle, and delivered in 3 an orderly manner for their utilization in different length or the number used in a nailing operation. In this connection, thedrum or other nail-container and the iaceway or i'aceways bywhich the'nails are delivered from the container are mounted to move together, as by pivoting theirsupport upon the Yframe, so that the raceways may be emptied back into the container. Nail-stops are asso ciated with the raceways andare movable between eective and ineffective positions, this being accomplished simultaneously for a plurality of the stops. I have shown means for thus selecting the stops in groups, so the operator may readily determine, with the aid of associated index means, the number of nails to be delivered throughthe raceways. Nail-reversing abutments or members asso ciated with a raceway or raceways are made movable by connect-ion with a setting member provided with index means,l so the desired position of the abutments may readily be determined for any length of nail. Such reversing means, without reference to the manner of its adjustment, is caused to move, during its variation in position to correspond to Vdifferent nail-lengths, in a direction inclinedv to the vertical. Consequently, the distances of an'abutment from the nail-supporting surface of the raceway and from the wall which limits the movement'of the nail during its reversal are simultaneously altered.

In the accompanyingl drawings, n

Fig. 1 is a front elevation of one embodiment of my invention, with parts broken away and in section; ,-x

Fig. 2 illustrates in broken side elevation the setting ldevices for the nail-stops and reversing abutments Fig. 3 shows the nail-separators and stops l including portions of an associated heel-attaching machine; and l Fig. 5 is a section through the distributing apparatus on the line V-V of Fig. 1.

A column 12 has, at the upper rear portion,

a bracket 120, upon which is pivoted about a sleeve `122 a supper-5.124 for the chief elements of the distributor.,(A` .pinv 126serves to detachably lock the support upon the bracket in its normalposition, and may be removed to allow the support and containing elements of the distributor to be tilted rear wardly for 4the purpose of emptying the nails. A nail-receptacle or container is carried by the support, this being shown, iupart, as a conical casing 128 integral with said support, with its interior accessible through a door 129. Secured to a wall 130 within the casing is a horizontal spindle 182, about which rotates a nail-drum 134, held releasably in place by a hand-nut 136 threaded upon the spindle. yBuckets 138 about the` drum successively lift the contained nails and empty them upon the diverging receiving walls 140 of the raceways. These raceways, of which eleven are herein shown, may consist of pairs of spaced bars 142, 142, upon which the nails descend, hanging vby their heads. To free the raceways of displaced nailsY which might interfere with the proper delivery, pairs of clearing Wheels 144. 144 are arranged upon a shaft 146 at opposite sides ot each nailconveyiiig slot. wheels are provided with inclined peripheiies formed with serrations, and when these are rotated in an anti-clockwise direction or so they falll into the casing and return to the drum. To rotate the shaft 146,v which is journaled horizontally across the forward end'of the casing, it is belted at 150 (Fig. 4)

This

The c f (Fig. 5), they act to rake back thedisplaced nails, either into position between the bars,

122. Said driving member is belted at 156 to the hub of a main driving pulley (not illustrated), and is controllable to produce engagement or release of the clutch, through a rod 153 extending through the sleeve andl provided with a handle 154. From the clearing-wheel shaft, rotation may be communicated to the drum 134 through a train of gearing 158 (Fig. 5), a shaft 160 journaled upon the support, and gearing 162. Toempty the distributor of its contained nails, it is tilted upon its pivot, so that the support leaves its seat upon the bracket, and theraceways become suliiciently inclined to cause all the nails in them to flow back by gravity through the open ends of said raceways into the drum. In this position, the distributor is held by contact of dependingl arms 167 with portions 163 of the frame. All the nails *being discharged vfrom the raceways, the operator has only to remove the nut 186, and, lowering the drum from the` spindle, empty it. Then it may be filled with nails of anotherlength, restored to its place lupon the` spindle, and the distributor and its support tipped back to the normal position. Extendlng between the column and each arm 167 upon the support, is a spring 165, which isv under constant tension. This acts as a coun terbalance for the weight of the tilting portions of the distributor, both-,during the nailemptying operation and during return movement. The double action is due to the fact that the arms 167 pass to opposite sides of the'vertical through the pivot 122 during the oscillation of the distributor.

It may be desired to supply nails, as to the jack of a heeling machine, from all the raceways or from but a portion. I have shown C five of the raceways as invariably conveying nails, while with the other six raceways means is associated for checking at will the flow through them, the control being exercised `in groups. In theV present instance, the groups C include, respectively, five, seven, nine and eleven raceways, though any other desired combinations might be employed. Mounted upon the support, above each raceway to be governed, upon a spring 164 is a stop-finger 166, the point of which mayeither occupy an effective position, in which it lies in the pathr of the nails, or may be so raised that it is ineffective. To allow the chosen combination of stop-fingers to be selected to cut off thesupply of nails through the corresponding raceways, there extends beneath the fingers a vshaft 168 journaled at opposite sides of the raceways Secured upon the shaft and co-operating with each finger is a cam 170, the finger being forced against the cam by its mountingspring. Fixed upon one end of the shaft ,is a handle 172, by which it may be turned, this handle carrying a spring-actuated latch-174, adapted to engage any one of fsix numbered openings 17 6 in an index-plate178. Theanv pears in Fig. 3 of the drawings, with its latch in the opening numbered 5. All the cams will now permit the stop-fingers to bar the associated raceways, so only those not controlled will be free. Or, when the latch engages the opening numbered 11, the cams act toy raiseallwthe fingers, so that the entire series of raceways deliver the nails.

Just before the nails leave the body-poi tions of the raceways andpa-ss upon more steeply inclined ends 179, which insure the proper advance of single nails, they are acted upon by separatingv devices, which pick them off one by one fordelivery. Each device` is in the form ofia disk 180, having in its periphery a notch Y182 of such dimensions that, whenbrought into registration with theupperor main portion of t-he raceway, it will re.- ceive a single nail, andv then, upon rotation of the disk, will transfer this to, the lower section, 179 and release it for delivery. Each disk is secured upon a shaft 184 journaled at one side of the raceway controlledand having fixed upon its lower end a lpinion 186. Tit-hy 'l which, at definite timesin the operation of L automatic loading 01 `transferring' mechanism for the jaclrof the associated heelattaching machine, may be driven by connection to a tubularshaft 260. In this manner, the lever 196', and therefore the separator-disks, are operated in Correct time-relation withthe loading mechanism.

lVhen the nails areftovbe driven upwardly into the work, as from a ack,- they must be delivered'with their heads down. verse them from the` positions they occupy upon the raceways, they contact with abutments 200 (Fig. 2), so located between the ends. 17 9 of the racew'ay-bars that-they restrain the depending points, while the heads, continuing their advance, overbalanceon the upper edges ofthe abutments. The'nails therefore lenter vertical passages 202 with their points up. Vll'iesepassages,areV formed between the forward extremity cfa-bracket 204 secured to thesupport 124 and a removable wall 206 held in place-byl screws 208. 1n caseof clogging, this wall'may be taken off to clear the passages. To. most effectively produce. the reversing action, thev abutments To reu must be diii'erently located for dilierent lengths of nails. I have therefore mounted them for adjustment in two directions--vertically toward and :trom the nail-supporting surfaces of the raceways, and horizon-rv tally to approach and retreat from the wall a liagonal movement of the abutments, or

at an angle to the vertical. F or this purpose, each abutment is provided with a slot i210 inclined upwardly and forwardly and having passing through it a supporting rod Q12 mounted at its ends inthe bracket 204. To move each abutment over the rod 212, there is shown connected to it an eccentric-rod 214 acted on by an eccentricQlG iixed to a shaft 218 journaled in the bracket below the raceways. Secured to one extremityof the shaft is a handle 220 having a spring-actuated latch 222 arranged to enter any one ot a series of openings 224 in an index-plate 226. The openings 224i may bear designations corresponding to lengths of nails which the distributor is to deliver. As illustrated in Fig. 2, the abut-ments are adjusted for acting upon the shortest nail which is to be used, the eccentrics 216 holding the abutments at their highest points and nearest to the wall 206. At this time, the lower end of the slot 210 is in proximity to the rod 212. I/Vhen the shaft 218 is turned by the handle to set the eccentrics at another angle indicated by the index-openings 224, the abutments are moved down upon the rod and simultaneously away from the wall. The upper edges ot the abutments therefore engage the longer nails farther from the heads, and greater space is given between these edges and the wall .206 'for the nails to reverse. From the passages 5202, the nails pass through curved tubes 228 to a set o delivery-tubes 230 mounted in a removable frame 232. The lower ends of the tubes 230 terminate in a foot-plate 234, in which they are arranged according to a nail ing design similar to all or a part ot the passages in the jack-top. of the frames Q32 with dierently arranged tubes will provide for the delivery of the nails in accordance with the design desired Jfor the insertion of the astenings.
