Be it known that 1, JOHN 'J. SULLIVAN, of Brooklyn, New York, have invented certain new and useful Improvements in Box-Nailing Machines, set fort-11in thislspecification and the drawings thereof. i V The invention consists of improvements relating to the hopper and the stops of the nailfeeder, and to themechanism by which the nail-feeder is operated, and to the connection therewith of the stopping, starting,and naildriving mechanism, whereby nails in bulk in thethopper will be placed in the nail-boxes singly and driven into the work. [Figure .1 is aside View of the machine. Fig.2is a front View of the same. Fig. 3 is a top View of the lower portion thereof with theupper part removed. Figs. 4, 5, and 8 are detail viewsfofportions of the machine. Fig. 6 is a sectional yiew of the nail-feeder, and Fig. 7 jisa toplyiew of the same.

In the form of construction shown, on the frame A, Fig. 3, are four bearings, B, in which are supported the journals 0 of the shafts D E. On the'shaft D is a .c lriyingu1ley',F, which is driven by abelt from. suitable drivingpower.

The driving-pulley F is loose 011 the shaft D,

and has a conicalrecess, G, into which is fitted a conical friction-pulley, H i The friction-pub ley H has a neck,K, with a flange, L, and is loose on the shaft D,"but is held from turning thereon bya' groove, M, and feather N. The friction-pulley His operated back and forth on the shaft D into and outof the conical recess G, to fasten orunfasten the pulleyF to or from the shaft D,by acollarf,O, on the neckK and an elbow-lever, 1?. The collar 0 is pivoted by bolts Qbetween the forks R of the short arm S of the elbow-lever P, whichlhas for its fulcrum rockshaft, U, .supported in bearings V in the. frame A. The longarm W" of the elbow-l ever 1? has a foot-piece, X, and a retractingspring, Y. By applying pressure to the foot-piece X when the pulley Fis in motion, theirictiompulley H is forced into the conical recess G in the pulley F, and byjfrictionfis locked therein and causes the shaft D to be driven. The pinion Z onthe end of shaft D drives the cog-wheel A on the end of shaft E, and gives motion thereto. On

shaft E is a pinion, B, and a cam-wheel, Of. The cam-wheel O has LG2L111 ,.D, on its side. On the shaft U is an arm, E, having at its upper end a roller, F, which rolls against the cam D on the cam-wheel O. The arm E is adjustable by set-screw G. WVhen the pressare is suddenly applied to thefoot-piece X, the lever I depressed, the friction pulley H engaged with the pulley F, and the shafts D E in motion, andthe pressure suddenly removed from the foot-piece X, the roller F operates against the cam Don the side of the camwheel 0, and holds the frictionpulley H engaged with the pulley F until one revolution of the cam-wheel G is made, when the roller F drops into a notch, H, at the end of the.

cam D and releases the friction-pulley'H from the pulley F, which is then drawn back by the retracting-springY against the friction brake K on theframeA, and themotion of shaft=D isstopped. i T

The brake K is adj ustable by setscrews in the frame A, and may press the edge or back of the friction-pulley H. As the motion ofjshaft Dis intermittent, dependin as it does, upon the operation of the elbow-lever P,the friction-pulley H, the roller F, and the mm D, sothe motion of shaft E is also intermittent. On the end of shaft E isa crank, L, which has a wrist-connection, ll with pitinan N, Fig.

.1, to which it imparts intermittent motion.

Pitman N is connected by awrist, 0, Fig. 2, to the segments P and imparts intermittent motionto them. The segments 1? are fixed at their centers to the ends of short shafts Q, having bearing S on the frame A and cranks T at their other ends. To the wrists, N of cranks T are. connected short pitmen V, which are connected at their other ends by pivot-bolts V tothe cross-head X and impart intermittent motion to it from the segments. The partsK L have channels V, which formnail-grooves U into which enter nail-tubesX Fig. 1. The nails descend through the nail-tubes X and the nail-grooves U into the nail-guides T and ontot-he closed end WV thereof, and rest on their points until the nail-punches descend, strike the nails on their heads, and force open the slides or dies 0 and drive the nails through the nail- 1 boxes E".

boxes Ff into the work to be nailed ,to form theboxes; The work is placed on alt-able, Y Fig. 2, under the nail-.box'es E and against a back plate, Z. The table and the back 5 -plate, 56, are both adjustable to suit the work.

The table Y is adjustable by arms A, passing through slots B in the back plate, Z, and-eons. nected with a block, C, through which passes an adjusting-screw, I)", supported at its lower end in a socket, E, on the framers, and hav-= .Y, on the end of a short shaft, Ztsupported Iin bearings A on the frai-ne A. The shaft Z hasa crank, 13*, connected bya wrist, C", to.

zo -pitman I), Fig. 1, to'which it imparts inter- Finittcnt motion. The pitman D". has azcom- 1 =-1 iensating-joint, Ff, and is connected at its up- 7 per end by slot and set-pivotF to a crank, G",

.-. on the end of an axis, H supported in bear- 2 5 ;ings I on the frame A.

On-the axis H? is supported by lugs and set so sews K, Figs. 7. and 8, a hopper, L, to which i nterm ittent motion isimparted by the pitman D i. Thehopper L has at its front insidejedge in- 0 'eli'ned chutes M andbeonduits N,- leading to -1 them.

The chutes h are inclined forward, .and in front .of each chute MB, on the frontof.

im-the hopper L areswinging guide-springs O. 1 '3 :The chutes M may be any number desired 1 5 to suit the work; Five 'is a very. convenient.

' number.- The swinging guide-springsclose the front of the. chutes M, and can be turned to one side to give access thereto? When lnails'areplacedi'nthehopper L 'in bulk, the

g inte'rmittent tilting motion of the hopper If forces the nails forward into the conduits h" and chute's M2, and back of the spring-guides into the inclined channels P, formed by z the V-bars Q having inclined tracks R be- Z15 .tween them." 1 Thenails drop point foremost into the 1 tracks R are held therein by their "heads, and slide down the tracks in single file.

'--The'V-bars have extensions S without the V,

.and arefadjustable to vary the width of the trackto suit different-sized nails by lugs. and

set-screws T The nails that doinotbeeome "suspended in the tracks and slide down therein drop through the spaces U A guard, V, is

.supported on cross-pieces X on the frame A. To a projection, Y", Figs. 1 and 2, on the with openings V to permit the nails inthe The V-bars are cross-head X. is pivoted by a pivot-bolt, Z",

The cams F, Fig. 7, operate intermittently againsta bar, H,

The pinion B, 3, on shaftEv imparts intermittent motion toa cog-wheel,

supported in inclined slots 1, Fig. 6, in the frame A,-and move the bar H 'backward in theslots I; The bar H is drawn forward again in the slots 1 by the retractingsprings K, Fig. 1. The cams G and compressionsprings L operate the bar M in the slots N in a similar manner. .Through openings in the bars and M, Fig. 7 are connected in a self-adjusting manner stops 0" P*, which pass through slots Q" in a supporting-bar, R, fastened to the frame A. The stops have compression-springs S" and nuts T, Fig. 6, to make them yielding and self-adjusting. The stops 0" in one position are held by the retracting-springs K, Fig. 1, and the compressionsprings S, Fig. 6, against the ends of the tracks R", and prevent the discharge of nails therefrom into the nail-tubes X and thence into the nail-boxes 13' under theiiaiLpunehes Ai",butv when drawn back by the vcams.F per- 'mit the nails to so descend. When the. stops 0 are drawn back, the stops 1? areforced forward 'andpermitbutone hail from each track B -to descend.

To the bar H ,,Fig. 7, is connecteda-rnis X, to which are adj u'stably connected by screws and nuts Y adjustable arms. Z, having end bearings A inwhich is supported a roller, 0, working on guides D. As the bar H moves forward, the roller 0- presses against the nails in the tracks R and susp'ends'the.movements of-the nails downward, but as the bar H is drawn back the roller 0* is raised from the "nails'onto the guides D and permits the, nails .toadvance. To the side of the hopper-1 iare pivoted arms E", which in a like manner, support and operate the roller F to cause thev nails'to be evenly distributed in the track-R". .Aplate, T having offsets U and slotsvV, is placed under the nuts T" of the middle stops 0", the outerstops 0 being. left free." The plate T is pivoted at V to thelever X, by which it is operated to force the offsets U. under thenuts T of the middle stops, 0", to render them inoperative or operative, and there- .byto stop or start the nailsin the correspondingl'tracks, tovar'y the number of nails to be driven at once.

The operating and starting and stopping mechanism, as described, and the nail-feeding and nail-driving devices in their general fea tures, as specified, are well known, and for them I make no claim, broadly.

The details of eonstruction'and operation may be varied within the scope of. the improvements.
