Specification of Letters Patent.

1 '0 all whom it may concern Be it known that I, HENRY W. MORGAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Nalling- Machines; and I do hereby declare the following to be a full, clear, and exact description of the same; reference being had to the accompanying drawings. forming a part of this specification. and to the reference-numerals marked thereon.

The present invention relates to nailing machines and it has for its object to provide improved mechanism of this nature more particularly adapted for driving a plurality of nails simultaneously into the several sides of an object, the machine of the present embodiment being designed particularly for nailing in the heads of kegs.

The improvements are further directed toward simplicity and toward promoting convenience and speed in operation.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a perspective view of a keg nailing machine constructed in accordance with and illustrating one 9. hodiment of my invention taken from a point to the right and in front of the machine; Fig. .2 is a pcrs ective view taken from the right in rear 0 the machine; Fig. 3 is a top plan view of the carrying frame for the nailing units showing the driving mechanism, the same beingtaken in horizontal section through'the supporting frame substantially on the line 3-3 of Fig. 1; Fig. 4 is a detail section taken substantially on the line 4-4 of Fig. 3 to show more particularly the manner of operating the nail drivers; Fig. 5 is a side elevation of one of the nail chucks; Fig. dis a top plan view thereof; Fig. 7 is a section taken substantially on the line 77 of Fig. 6, and Fig. 8

is an end elevation of one of the nail chucks. Similar reference numerals throughout the several figures indicate the same parts.

To first give an idea of the general arrangements of the machine it may be said that in the present embodiment the keg or work iece is designed to remain stationary beneat a vertical y sliding mechanism that l is brought down upon it to position a plu rality of nailing units circularly about the same, while after the nailing operation the mechanism is raised to release the work piece which is removed and replaced by another.

Referring more particularly to the drawings, 1 indicates a substantially vertical main supporting frame at the base of which is arranged the work support 2. The'latter may be of any suitable nature, being in the present instance shown to comprise a truck traveling on tracks 3 and forming art of a conveyer by means of which the regs are delivered to and removed from the machine, but it will be later understood that a simple platform or, for that matter, the floor upon which the machine rests, might be utilized in this-capacity.

V Slidable vertically up and down'above the work support on guides l on the frame 1 is a preferably annular carrying frame 5 upon the upper side of which are mounted a plurality of nailing units embodying chucks 6 that are arranged radially to drive the nails toward a common center. The chucks are each independently adjustable toward and from the center of the annular carrying frame in guides 7 being secured in adjusts 8 operating in slots 9 in the frame, the latter being indicated in dotted lines in Fig. 4. The inner ends of the chucks are each preferably provided with depending fingers 10 that, in the resent instance, project downwardly within the central opening of the annular frame 5 and have inclined faces 11, the purpose of which is to center the keg or work piece properly with respect to the chucks as the latter are lowered upon it, as will be understood from an inspection of Fig. 5.

Each chuck comprises a lower portion 6 and an upper portion 12, the adjacent faces of which are suitably recessed to conjointly form the nail channel 13 and the channel for the driver ll. The latter is provided with a cross head 15 at its outer end that travels in a way 16 in the lower member 6 and is held in place by a cover plate 17 at the top, while at the inner endof the nail channel a sutiicient recess is provided for the accommodation of the lower yielding chuck jaw 18 which .is pivoted at 19 to the member 6 and pressedupwardly by a spring 20 arranged in a pocket 21 in the'iatter.

position in any suitable manner, as by bolts The 0 osing ieldin jaw-22 is yoke-shaped so tha f the upiier rendovable block 12 of the chuck may be accommodated between 1ts arms 23, which are pivoted at 24 to the member 6, while the said block is undercut at 25 to accommodate the end of the j aw beneath it, this portion of the block 12 be ng also provided with a ocket 26 containing a spring 27 which ears against the stud aw 22.

The upper block 12 is itselfheld 111 place for relative movement toward and from the lower portion of the chuck by pins 28 on the latter fitting recesses therein and by a yokeshaped clip 29 that straddles the block 12 and has the lower hooked ends 30 of its arms detachably engaging pins or projections 31 on the portion 6. This clip holds the block yieldin ly'in place by the en agement therewith o a spring 32 arranged in a pocket 33 in the block so that the latter may accommo date itself readilv to irregularities in the passage of the nail through the nail channel, and it will also be seen that the block is removable by simply detaching the clip 29 so that access may be had to the nail channel when necessary. The feed channel 34 that delivers the nails to the nail channel 13 is formed in the upper block 12 of the chuck, the nails entering at-its mouth 35 from the nail feed, as will be hereinafter described.

The drivers 14 of all the nailing units are simultaneously operated by a'rock shaft 36 that is journaled at 37 in a bridge piece 38 spanning the annular carrying frame 5 in a manner to support the latter so that the frame is virtually hung upon this shaft. Se cured to the lower end of the shaft as it projects through the bearing 37 is a member 39 having upper and lower laterally projecting flanges 40 and 41 that are spaced longitudinally of the shaft and to these flanges alternately are pivoted at 42 the respective'ends of connecting rods 43, the opposlte ends of which have hooked portions 44 that enter at the sides of the ways 16 of the chucks and cooperate with the cross heads 15 of the drivers,the outer ends of the latter being provided with pins 45 with which the hooked portions engage to withdraw the drivers, while a ball 46 is preferably interposed between the hooked portion 44 of each rod and the main portion of the cross head that receives the driving pressure to reduce friction. It will thus be seen that as the shaft 36 is rocked the connecting rods will travel in and out and operate the drivers, and the purpose of pivoting these connecting rods alternately to the flanges 40 and 41 is to allow them to clear each other and not interfere when an extreme stroke is made. It is notthought necessary to further describe the manner of driving the nail.

The upper portion of the shaft 36 is slidably journaled at 47 in a forwardly extend ing bracket 48 on the supporting frame 1 and a counter-weight 49 is connected by a chain 50 passing over pulleys 51 and 52 to the end ofthe shaft so that the shaft and the frame 5, that it carries, may be raised and lowered with little effort on the guides 4, and for the purpose of thus manipulating it a downwardly projecting rack bar 53 is provided on the bracket 48, with which meshes a pinion 54'on a shaft 55 journaled in the bridge piece 38 of the same and provided witha wheel or handle 56 that the operator may manipulate from the front of the machine, as the work pieces are put in place on the work support 2.

The function of the projections 10 on theseveralchucks for centering the latter over the keg or workpiece as the frame 5 is lowcred, has been before described, but in order to first properly approximate the position of the work piece on the support, adjustable stops or abutments are provided on the frame 1 having the present form of laterally projecting screw-bolts 57 that are held in adjusted position by lock-nuts 58. The kegs are thrust against these when inserted and in order to halt the downward movement. of the frame 5 carrying the nailing units so that the latter will deliver at the proper point, as at the chime A of the keg B having the head C, (Fig. 5) adjustable stops 59 are threaded into brackets 60 on the bridge piece 38 of the frame that engage the top or head of the work piece as the frame is lowered.

The shaft 36 is driven by a shaft 61 journaled in brackets 62 and (Ben the main frame, which shaft 61 is itself driven through gearing 64 and 65 from a shaft 66 that is in turn driven by gearing 67 and 68 from the main driving shaft 69 having a belt pulley '70 thereon. A suitable clutch mechanism (not shown), controlled by a hand lever 71 accessible at the front. of the machine, throws the gearing .6465 between the shaft 66 and the shaft 61 in or out of operation at the will of the operator by disconnecting the gear 67 from shaft 66 or the reverse, so that the shaft 61, and with it the nail driving mechanism is operated intermittently, as desired, from the continuously turning main driving shaft only when the driving units are in proper coiiperation with the work piece.

The connections between the shaft 61 and the rock shaft 36 for operating the latter, comprise a crank 72 on the upper end of the shaft 61 to which is attached a connecting rod 73. The other end of this connecting rod is pivoted at 74 to a crank 75 on a sleeve 76 that surrounds the shaft 36 within the bearing 47 on the bracket 48 and turns freely in the bearing while being locked against rotation on the shaft 36 in any suitable manner, as by the key 77 that per-' nuts the shaft 36 to slide longitudinally within the sleeve and bearing. The crank 72 is shorter than the crank 7 5 so that as the former revolves with the shaft 61 the,

latter only oscillates and rocks the shaft 36 to operate the connecting rods 43 and actuate the drivers 14, as before described.

When the chucks 6 of the nailing unit are adjusted inwardly or outwardly on their guide 7 to accommodate the machine to kegs or work pieces of different sizes, the limit of the throw of the drivers 14; must, of course, be correspondingly changed, and to effect this I provide the connecting rod 73 between the shafts 61 and 36 with threaded portions 78 by means of which it may be -le11gthened or shortened and the crank 75 thus be made to move through an arc of greater or less degree upon the rotation of the crank 72;

The nails are fed to the months 35 of the feed passages 34 in'the upper blocks 12 of the various nailing units, through lower feed tube sections 79 carried with the frame 5 that telescope upon upper sections 80 leading from the usual, or any preferred form, of nail hoppers 81 so that the upward and downward movement of the frame 5 does not interfere with the nail feed.

As to the other necessary accessories of the nailing machine, these have been shown generally in the drawings, but it is not thought that they require any detailed description as they form no part of the present inventi n.
