Buckley, Beverly, Mass.,_ assignor to United Shoe Machinery Corporation, Paterscn, N. J., a corporation of New- `ïersey Application October 29, 1935, Serial No. 47,283 13 Claims. This invention relates to apparatus, commonly known as distributors, by which such fastenings as nails may be taken from a mass and delivered in loads, each including a definite number of 5 fastenings all arranged with their points in the same direction. This may be for the ,successive delivery of the loads of fastenings to a heel attaching machine. ‘ . In apparatus of the character above indicated, 10 a well-known arrangement is that disclosed in Letters Pat-ent of the United States No. 1,005,303, Pope, October l0, 1911. The fastenings are re ceived by the apparatus of that patent from a rotary drum upon a grooved raceway, without l5 any deñnite direction of the heads and points, and are acted upon during their passage between vertical adjustment, the distance of the revers ing member below the upper raceway-section may be established, while by the horizontal adjust ments the alinement of the grooves in the re versing :member and in the raceway may be fixed accurately> and also -the normal space be tween the extremities vof said reversing member and the raceway determined. I prefer to obtain these variations in positionV by a mounting for the reversing membenwhich mounting comprises 1,0 two supporting members respectively movable to give the effect sought and conveniently clamped in place by screws passing through open ings which give a capacity for relative lateral movement between said screws and the elements 1.5 secured. kAs herein illustrated, the adjustable upper and lower raceway-sections vby a, reversing member termed a balancing-bar. This device permits the nails moving heads ñrst along the 2O raceway to pass unaiîected, but receives in grooves corresponding to those of the raceway the means for the reversing member which adapts the apparatus for operating upon fastenings of different lengths and which commonly includes fastenings advancing points first and inverts ber are thus positioned together by the supporting them, so all reach the lower raceway-section sim ilarly positioned. To allow the reversing device means to maintain the desired relation between the elements. 25 to act accurately, its grooves should be alined transversely with the grooves of the upper race way-section and should bear to them a prede Fig. l is a fragmentary perspective View of one termined vertical relation. Moreover, though it is customary to provide an adjustment where 30 by the distance between the rear edge of the re versing device and the forward extremity of the mounting acts also upon the usual adjusting ` a rack and pinion. These and the reversing mem In the accompanying drawing, embodiment of my invention; . Fig. 2 is an enlarged perspective view of the more essential portions thereof; and ' Fig. 3 is a transverse sectional detail in the plane of a pair of upper and lower adjusting upper section may be varied to adapt the appa screws. ratus for operation upon fastenings of different lengths, it is desirable that there shall be estab There is shown, corresponding in general ar rangement to the like elements of the previously 35 lished a normal relation of parallelism between the elements, from which the various adjustments may be made. Heretofore, the usual practice has been to create all these normal positions when the apparatus is assembled. It is found, however, 40 that manufacturing irregularities and wear in use zo , 0 ' mentioned patent, a portion of an oscillatory ¿V raceway-frame I0 in which are carried parallel upper raceway bars I2 and lower b-ars I4. In alined grooves I6 in the bars of the upper and lower sections, the nails or other fastenings to be separated into loads are conveyed. Just in’ 40 disturb the preferred relations, so diniculty is advance of the forward ends of the bars I2 and experienced both in setting up and maintaining above the rear extremities of the bars I4 is a the apparatus. It is an object of my invention reversing member in the form of a balancing-bar to so organize fastening-distributors of the kind I8, containing grooves 20 which should be alined 45 previously indicated, that the correct relation be ’ with the grooves I6 and which should also be at 45 tween the elements may be established readily at their rear nail-receiving ends a definite distance the time cf their assembly and such relation re below the adjacent ends of the grooves in the stored if it is later disturbed. In the attainment bars I2. Nails traveling heads ñrst down the of this object, I furnish the reversing member upper raceway-section are so tilted downwardly 50 with separate adjusting means wherebyits rela by the weight of the heads as these leave the 50 tion to the raceway may be varied independently bars I2, that they pass beneath the balancing-bar in different directions, one of which is preferably I8 and continue on down the lower raceway approximately horizontal while another is ap section; but when the points of the nails are proximately vertical. 'I'ne horizontal movement forward, they bridge the space between the bars 55 may bein a plurality oi directions. By the chosen _l2 and the balancing-bar, contacting with the 55 2 _ 2,113,571 latter as their points enter the grooves 20. When the heads leave the bars l2 in the continued ad vance of these nails, the support of the points nished by the openings 36, be shifted independ ently at its ends toward and from the upper sec tion of the raceway to give a uniform space which wardly so the heads pass iirst beneath the bar and thus proceed downwardly in the grooves will be maintained for all adjustments made by the shaft 25 and associated gearing for different lengths of nails. Having thus described my invention, what I in the lower raceway-bars I4. Consequently, al1 claim as new and desire to secure by Letters Pat upon the balancing-bar causes the direction of travel to be reversed, they overbalancing rear the nails are delivered from the raceway in the 10 same direction. If the length of the nails in use ent of the United States is: 1. In a distributor for fastenings, a raceway, a varies, the space between the bars I2 and the reversing member arranged for contact with fas balancing-bar must, of course, be similarly changed. For this purpose the balancing-bar is arranged to slide upon the frame I0 and has tenings traveling along the raceway, and plural 15 at each end a rack 22, with which racks mesh pinions 24 upon a shaft 26 rotatable by a hand wheel 28. By turning the hand-wheel the op erator may lessen the space to be bridged by short nails and lengthen it for long nails. Such a single adjusting device for the balanc 20 ing-bar as that just outlined furnishes means only for a change of nail-size, and leaves the correction of manufacturing defects and mainte nance-difficulties unprovided for and frequently 25 requiring considerable labor. The present in vention furnishes means for readily obtaining the proper relation of the elements. At each side of the frame I0, in the same general location in which the balancing-bar has been arranged to 30 slide longitudinally of the raceway in previous organizations, I arrange for like movement in approximately horizontal direction a bracket 30. This bracket may be in the form of an angle piece having a horizontal arm 32 extending 35 transversely of the raceway, and from the outer adjusting means arranged to independently vary the relation of the reversing member to the race way in directions substantially at right-angles to 15 each other. 2. In a distributor for fastenings, a raceway, a reversing member arranged for contact with fas tenings traveling along the raceway, and a mounting for the reversing member comprising two supporting members, one of said supporting members being variable in position upon the raceway approximately horizontally and the other member being variable in position upon the first supporting member approximately ver 25 tically. 3. In a distributor for fastenings, a raceway, a reversing member arranged for contact with fastenings traveling along the raceway, and a mounting for the reversing member comprising two supporting members, one of said supporting members being variable in position upon the raceway approximately horizontally and in a plu rality of directions and the other member being variable in position upon the ñrst supporting ‘ edge of which horizontal arm rises a vertical arm 34. Through the arm 32 are spaced openings 36, member approximately vertically. 36, which receive clamping screws 38, 38 threaded into the frame. The openings are larger in di reversing member arranged for contact with fas tenings traveling along the raceway, and a 40 ameter than are the screws, so there is such clear ance that the bracket may be adjusted in all 4. In a distributor for fastenings, a raceway, a mounting for the reversing member comprising 40 two supporting members, one of said supporting directions horizontally and fixed in position by members being movable upon the raceway and tightening the screws. Through the arm 34 of each bracket are two substantially vertical slots the other movable upon its companion support ing member, one of said supporting members 45 40, 40 receiving screws 42, 42 securing upon the bracket a block 44. This block has an approxi mately horizontal flange 45 and upon this one end of the balancing-bar I8 is arranged to slide. Fur ther, the bar-adjusting shaft 26 is journaled in an 50 upward extension of the forward portion of each being provided with openings, and clamping screws passing through the openings and being threaded into the raceway and into the other supporting member, there being a capacity for relative movement of adjustment between the screws and the elements which they secure. 50 block so said shaft and bar may be moved to 5. In a distributor for fastenings, a raceway, a _ gether, maintaining the racks 22 and the shaft member co-operating with the raceway and adapted to reverse end for end the positions which fastenings have occupied in said raceway prior to their contact with the member, means arranged to adjust the relation of the reversing member to the raceway to adapt it to operate upon fastenings of different lengths, and sepa rate means arranged to vary independently the relation of the opposite ends of the reversing 60 member to the raceway. pinions 24 always in mesh. It will be seen that the two supporting members 30 and 34, with their 55 respective adjusting means 3B, 38 and 40, 42, fur nish a universal mounting for the balancing-bar and its adjusting gearing. If, either in the as sembling or the use of the apparatus, it is found that there is not a proper vertical relation be 60 tween the grooves in the balancing-bar and the grooves in the race-way bars l2, it may quickly be righted and the desired normal position attained by loosening the screws 42, raising or lowering the block 44 with the balancing bar and its adjusting 65 shaft 26 and then resetting the screws. Or, if the raceway-grooves and balancing-bar-grooves are out of alinement transversely, an adjustment of the bracket 3D and the balancing bar upon the frame under the control of the screws 33 will correct this defect. These screws 38 are readily accessible through openings 46, 46 located in the block 44 at one side of the screws 42, 42. In ad dition to this transverse adjustment of the bal ancing-bar-grooves, the bar may, by virtue of the clearance on all sides of the screws 38 fur 6.
