ALBERT E. HUDSON, OF BEVERLY, MASSACHUSETTS, ASSIGNOR T UNITED SHOE MA- CHINERY GOfiPORATIQN, 01* PATERSON, NEVJ JERSEY, A CORPORATION OF NEW JERSEY.

NAIL DISTRIBUTOR.

Application filed February 12, 1.923. Serial No. 618,591.

To all whom it may concern.

Be it known that l, ALBERT E. Honsorn;

a citizen of the "United States, residing at Beverly, in the county oi Essex State 5 of Massachusetts, have invented certain Improvements in Nail Distributors, oi which the following description, in connection with i the accompanying drawings, is a specifier tion, like reference characters on the drawings indicating like parts in the several figures.

My invention relates to nail-distributors,

and more especially concerns, in such apparatus, the discharge mechanism generally organized in the manner disclosed in the application for Letters Patent iiled in the name of Frederick J. Balcom on September 2, 1921, and bearing the Serial Number 98,074. In this arrangement, the discharg 2 ing member or rotatable roll, which receives nails from a raceway and delivers them in successive charges to the machine supplied,

. has, co-operating with it, a barv or other stop member, which temporarily retains the nails upon the roll until a charge has accumulated, and then yields under the influence or" the rotation oi said roll to permit delivery. The stop-bar. is adjustable, in an approximately horizontal direction, toward and from nail-receiving openings in the roll to properly position nails or dill'erent lengths, and, normally, its inner edge lies.

over a nail-directing surface, which continues the support aliorded by the walls of the openings in the roll. It has been found desirable to have not only the openings, but also the continuing walls, inclined downwardly in the direction of delivery to facilitate the advance of the nails during their reception by the roll and their positioning by the bar, and to prevent accidental displacement by changes in their course. This inclination causes the directing surface to diverge downwardly from the plane to its independentadjustment.

charge device of the-character mentioned,

for such a relation between the stop member livery of the; nails. To attain this result, the stop member or bar is not only movable toward and from the discharge device or roll in accordance with the length of the nails acted upon, but also in another direction, so as to control its normal relation to the directing surface, and thus compensate for the divergence between the member and the co-operating surface of the roll. The stop member is shown as being a composite device, including a body-portion or plate adjustable toward and from the openings in the discharge device, and a stop-bar, which receives the contact of the nails and which may be adjusted upon the body-portion. Preferably, between this body-portion and stop-bar is a carrier member or slide, arranged to yield upon the body-portion, and to which the stop-bar may be pivoted for This interposed yieldable member permits of the actuation of the stop member by the dischargeroll in its rotation.

A particular form which this invention may assume is illustrated in the accompanymg drawing. 1

The general nail-distributing organization may be similar to that disclosed in Patent No. 1,005,308, Pope, October 10,1911. This includes a nail-conveyor or raceway 10 arranged to oscillate upon a frame 12 and provided with inclined grooves or nailavays i l carrying the nails from a drum or container (not illustrated) in series in each of the ways, as appears at N in Fig. 4 of the drawing, to the discharge mechanism D. The discharge device proper consists of a roll 16 journaled horizontallv for rotation upon the forward end of the conveyorframe. Thisroll is oscillated from the nailreceivlng position, shown in Fig. 4:, to the nail-discharging position, illustrated in Fig.

5, by a crank-arm 18 fixed to the spindle of the roll and operated through a link 20 and a lever 21 from a cam 22 upon shaft 23, this shaft being constantly rotated while the apparatus is inaction. (lo-operating with the nail-ways are the usual stoplingers '24, oscillated from a cam on the discharge rol'hspindle to alternately release the nails to permit their travel down the nail-ways to the discharge mechanism, and

to check this advance while said discharge mechanism is operating.

Extending longitudinally of the axis of the discharge-roll is a recess 25, which, approxii'nately, has the form produced by removing t'rorn the roll a sector of about 105 degrees. In the normal or nail-receiving position 01 the roll i), a wall 26 of the recess is inclined doi'vnwardly from the horizontal, while the other wall 28 extends substantially vertically. 'Jpening through the wall 28 and through the opposite side otthe'roll is a series of transverse perforations 30, corresponding in number to the nail-ways, being alined with them, and having the same inclination when the discharge roll occupies the nail-receiving position. Th s inclination is continued by grooves 31 in the directing suri ace 2, a convenient manner of producing these grooves being by drilling them simultaneously with the openings 30. lit will be seen that when the series N of nails are released by the elevation of the lingers 2 1-, a continuous downwardly sloping surface is afforded, along which the nails travel until they are stopped by the devzce hereinafter described. Since there is no change in the direction of their travel, they proceed, witliout liability to 31, which at the opposite extreme position or the roll,

recess 25, so t displacement by the vibration of the machine, this maintenance of their true relation leing aided by the presence of the grooves ord them lateral support. In

alined ment of Art each end of tee bar 32 is anarm 8%, pivoted at the opposite e3:-

tremities of a carrier member or bar 38 situated just in front of the bar 32, and having a forwardly extending portion 40 arranged to slide in a wav 12 in a plate 44, 't'urnishing the body-portion of the stop device and carried upon the conveyor-frame. 'lhe plate 44 is mounted for adjustment toward and from the discharge-roll, to change the distance between the surface at or" the stop-bar and the openings 30 in the roll, by a shaft as, journaled in the conveyor-frame, arranged to be turned by hand-wheel 48, and having pinions 50, 5O meshing with series of raclr teeth 52, 52 upon the upper The stop-bar is pressed ings two of which may be employed, these springs being contained in bores at the outer edge of the plate. The forward extremities of the bores are threaded to receive screw-plugs 56, against which the inner ends of the springs abut. By turning these plugs, the "force with which the springs resist the movement of the stopbar may be varied. The intersection of the wall 28 with the cylindrical surface 01 the roll 16 furnishes a cam or contactprojection 58 arranged to strike, in the oscillation of the roll, upon the stop-surface 34 of the bar. This engagement forces the stop-bar and carrier-bar away from the roll, as is illustrated in 5, the springs '54 yielding to permit this, until the path of the nails carried upon the surface 26 is cleared, and they drop into the deliverytubes.

Threaded through the center of the rear portion of the carrier-bar 38 is a vertical screw 60, having a finger-piece or head 62, by which it may be rotated to raise or lower it in the bar. It may be fixed in its adjusted position by a lock-nut 64 bearing against the upper surface of the bar. At its lower extremity is a flange or enlargement 66, the edge of which enters a recess in the adjacent wall of the stop-bar. When the locknut is loosened, the screw may be turned, so that its portion (36, acting upon the bar, will either raise or lower this, and thus change its normal relation to the surtace 26 of the discharge-roll. When the desired adjustment is obtained, the screw may be locked in position by the nut.

In using this discharge device, the stopbar 32 is adjusted in substantially hori- Zontal direction by moving the body-portion 4A- through the gearing 50, 52 until the wall 3% is in such a position that the contact of the forward ends of the nails, they lie in the openings 30 and grooves 31, will bring the opposite extremities just outside the periphery of the roll to hold the succeeding nails in the ways 1 spaced from said roll. This is as illustrated in Fig. l. If a shorter nail is to be operated upon, the shaft 4.6 will be turned to bring the wall 34 nearer to the forward ends of the openings 30, or if longer nails are to be used, the stop member will be moved by its gearing in the opposite direction. If the first-mentioned change in location of the stop-bar is to be made, the screw will be turned to lift the bar, the final adjustment being such that the lower edge of the bar will just clear the surface 26 between the grooves 31. When adjustment is made for a longer nail, the stop-bar will be lowered, the space between its lower edge and the surface 26 being kept constant for all horizontal positions. As the -roll oscillates in the direction of the arrows in Figs. f and 5 to discharge the nails, the camprojection 58, operating against the stopsurface 3%, forces the bar forward, the springs 54 yieldin Thus, the roll moves the bar out of its path, as is particularly shown in Fig. 5, leaving said roll free to complete its oscillation. This at once carries the stop-surface away from the extremities of the nails resting in the grooves 51, so that there is nothing to prevent their discharge into the receiving conduits, into which they fall by gravity. As the reverse movement of the roll occurs, the springs 54 cause the bar to follow the projection 58 back to the normal position, whereupon the nail-receiving and discharging operation is repeated.
