SPECIFICATION forming part of Letters Patent No. 490,624, dated January 24, 1893.

Application filed April '7,1892. Serial No. 428,154. (No model.) I

To all whom it may concern.-

Be it known that I, LOUIS GODDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Nailing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In the machine herein to be described headed nails are thrown in bulk into a hopper having co-operating with it a rotating lifter containing suitable buckets which deposit the nails on the upper end of a raceway down which the nails travel, the nails being let off one at a time by a separator which is moved at the proper intervals to permit the endmost nail in the chute to enter a driver passage in a nose where it is acted upon by a driver and driven therefrom into the material. Oo-operating with this driver-bar is an independent awl-feeding device which engages and moves the material. The raceway is made movable longitudinally with the vibratory head having the driver and awl bars, so that the roadway always preserves one and the same relative position to the nose.

The particular features in which this invention consists will be hereinafter described and pointed out in the claims at the end of this specification.

Figure 1, is a right-hand side elevation of the upper part of a nailing machine containing my present improvements together with part of the horn. Fig. 2, a front elevation of the machine shown in Fig. 1, the lifter oo-opcrating with the hopper being removed. Fig. 3, a detail showing the separator. Fig. 4, a detail showing the cam 9 Fig. 4!, a detail showing. the feed arm D. Fig. 4. a detail showing the stud of the feed rocker. Fig. 5, a section to the left of the dotted line or, Fig. 1, some of the upper part of the machine being broken away. Fig. 6, a detail showing the inner side of the lifter. Fig. 6, a detail showing the chute and clearerin section. Fig. 6 shows the rear part of the clearer, the front part shown in Fig. 2 being removed. Fig. 7, a sectional detail in the dotted line 00', Fig. 1, looking to the left. Fig. 8 is a top view of the raceway and a section of part of the swinging frame and nose piece. Fig. 9, a

the front end of which is a disk e, having a lug or projection ewhich, in the rotation of the shaft, acts on a projection e attached to the driver-bar a, provided with a driver a The driver-bar is mounted in a movable head B, which is adapted to be oscillated, as will be described, during the operations of the machine. The upper end of the driver-bar has ball-jointed to it a link 6, in turn connected with a lever e acted upon by an adjustable spring e, the latter serving to throw down the driver-bar quickly whenever the lug or projection 6 passes the projection 8 On the outer end of this main-shaft O is secured a suitable fast pulley, and at its inner side is a suitable loose pulley, the two constituting a friction pulley device, the loose pulley (driven constantly) being forced in contact with the fast pulley at the proper times by a wedge 0 at the upper end of a rod 0 attached to a suitable treadle (not shown), so

that when the operator puts his foot upon the treadle the wedge is elevated, it acting against a loose collar 0 interposed between the wedge and the loose pulley, which is forked to embrace the shaft and the hub of the loose pulley. Fast on this shaft 0 is a cam 0 having in one of its faces a suitable groove, shown by dotted lines in Fig. 7, in which enters a roller or other stud of a lever 0 The lever C is connected to a rod C or foot-plate b has at its under side an edgegage (i made adjustable by a rod 01 suitably toothed to engage teeth connected to or forming part of the said edge-gage, the said rod having a handle (1.

The work or material into which the nails are to be driven will rest upon a born 14, a part of which is shown in Fig. l.

The parts so far described and referred to by letters and figures are common to United 10o States Patent No. 265,227, and in the foregoing description I have aimed to employ letters and figures common to similar parts in the said patent, but in the said patent Fig. 11 shows the nose en- 55 The nose 9o the collar acted upon by the wedge C was not lettered and herein the earn 0 has been somewhat altered, as I shall presently show. Herein the cam C is made larger in diameter and its periphery is beveled off on its two sides, and I have provided a brake-shoe I3 correspondingly grooved to fit the said beveled edges, the said brake shoe by acting upon the surface of the cam serving to check the rotation of the said shaft more quickly and unerringly after each nail or fastening has been driven.

The brake B,bestshown in Fig. 7, is shaped as a segment, pivoted at B on an arm of a sleeve B mounted upon a stud B, fast in an ear of a bearing B, see Fig. 1, forming part of the frame or head A. The hollow hub or sleeve B has an upright arm B provided with a roller or other stud B which, in the rotation of the shaft 0 acts against the periphery of a cam B attached to or forming preferably a part of the cam 0 the said roller B being represented as mounted upon a stud 13 made adjustable by a suitable screw or adjusting device B in a slot at the upper end of the said arm. The sleeve B has also an arm B provided with a toothed segment B see Fig. 7, which engages a rack B on the rod or bar C the said bar, as before stated, being common to the said patent, but in the said patent the said bar does not have the rack-teeth B referred to.

The shaft C has fast upon it a cam D, having at its rear side a cam-groove 3, represented by full lines, Fig. 5, in which enters a roller or other stud carried by an arm D, see Fig. 1, fast on a rock-shaft D extended through a bearing D forming part of the head A, the said rock-shaft at its front end having afeed arm D, grooved at its front face at 40, as represented at Fig. 4, to receive the foot of a 1101- low stud D fitted to slide in the said groove, the said stud having screwed into and through it a stud-screwDfitheinnerend of which meets the arm D", the stud being embraced loosely back of the screw-head by two like blocks D the fiat faces of the said blocks entering and sliding in a slot D formed between a part of the rocking head 13 and a finger E the latter being adjustably connected therewith by a suitable set-screw B", the connection between the finger B and the head B being further effected by a tongue on one entering agroove in the other, adjustment of the finger B compensating for wear of the blocks and stud. As the rock-shaft D is vibrated, it will, as will be seen from the foregoing description, vibrate the frame B about the usual circular projection upon which it turns, the said circular projection forming part of the usual head A, and being common to the patent referred to.

The cam D at its front side has a camgroove f, represented by dotted outlines in Fig. 5, said cam-groove receiving a roller or other stud f, at the inner end of an arm f the hub of which is suitably attached as terial resting on the horn or other work-sup" port below the foot 0 The lower end of the awl-carrying-bar is slotted at 6, see Fig. 9, to constitute a clamp, and the awl is held in position by means ofa set-screw 7 screwed through the awl-bar,and the awl may be moved laterally in the said slot to place it at the proper distance from the nose of guide E see Fig. 11, into which the nail to be driven is led from the end of the raceway F to be described, the said nose containing a nail passage, the driver entering the said passage and striking the head of the nail therein. This adjustment of the awl laterally provides for making a hole in the material at the proper distance from the last nail driven, or, in other words, enables the spacing of the nails to be determined correctly and finely. Thelower end of the awlhas to be steadied, and to do this I have provided a guide E, which is adjustably attached by the screw 8 to a flange 9 forming part of the nose or nail-receiving block E the latter being attached to the rocking frame 13 by suitable screws as 10 in holes 10*.

The awl guide E referred to, and as shown best in Fig. 8 in section, has a series of holes 12, either one of which may be entered by the awl, in its adjustment, as provided for, in the slot in the awl-bar, the guide having, it will be understood, any suitable number of holes at the proper distances apart.

I have shown the nail-receiving block detached in Fig. 11, and it will be noticed that it has a nose 14, which in practice is adapted to enter a slot in the foot 13 The nail-receiving block and its nose travel with the material, in the direction of the feed thereof while the awl is in the material the horn at such time being depressed to release the work, as provided for in the said patent. Herein the rocking frame 13 is provided with suitable bearings g, for a stud g on which, as herein represented, is clamped by a screw 9 a lever 9 provided at its upper end with a roller or other stud g*, which bears against a cam face forming part of the disk e, the said disk being enlarged suliiciently beyond the size shown in the patent referred to, to present this cam surface outside the lifting cam e. A suitable strong spring g, attached to the frame B, acts upon a suitable stud g forming part of thelever g and serves to keep the said roller g against the cam. The lower end of the lever g see Fig. 3, has attached to it a gate or separator y it having a slot 16 to embrace the ear or prong 17 at the end of the raceway F. The nail-receiving block is notched or shouldered at two ICO . clamped by a screw F the split hub of a carrying frame F, suitable set-screws 23 acting upon suitable projections 24 extended laterally from the raceway to confine thelatter in working position. This frame F is bored out at 25 to receive loosely a guide-rod F the said frame and guide-rod being splined, however, one to the other, to prevent rocking movement of the frame F yet permitting the said frame to slide upon the said guide-rod when the rocking frame B is being swung during the feeding operation.

The guide-rod F referred to has a hub which embraces a pin 27, carried byalever G, mounted loosely upon a stud or stationary shaft G, held in suitable bearings G the outer end of the said lever G having a bearing in which is mounted the shaft G to which is connected the rotating lifter or drum G provided with lifters or shelves G which pick up the loose nails and drop them upon the shelf G fixed to the hopper G and in communication with the upper end ofthe raceway F so as to enable the nails dropped therein to fall on the upper end of raceway. The shaft G has a pulley G see dotted lines Fig. 2, which receives a belt G driven bya pulley G fast on a toothed gear G loose on the stud G, the said toothed gear being engaged and driven by teeth h, herein represented as made in the hub of the cam D. The hopper G is shown as a fixed part of the lever G. The hopper is shown as a disk concaved at its front side, and at its upper side it has a box-like projec tion G down through which the nails are discharged into the nail-pot composed of the disk and the lifter referred to. The face of the disk-like portion G is notched, see Fig. 1, to receive and guide the upper end of the raceway, the latter, by its connection with the frame B as described, sliding in the said notch with the said frame during the operation of the machine. The lever G has suitable bearings for a clearer shaft n, provided at its rear end with a pulley n'driven by a belt 71 from a pulley a moving with the pulley G. The front end of this clearer shaft has a clearer herein represented as com posed of two toothed disks n a, made so merely for convenience of manufacture, the said two parts being represented as connected by a pin a on one entering a hole in the other part, see Fig. 6. The larger part n of the clearer, is provided with a series of conical teeth, as best shown in Fig. 6, adapted to sweep over one of the beveled sides of the top of the road-way so as to remove any nails lodged crosswise on the raceway, the other smaller part a of the clearer having ratchet-sh aped teeth which are located immediately above the slot in the raceway so as to dislodge any nails coming down in the slots with their heads not properly seated to ride in the raceway, or those sliding down thereon point or head foremost.

The lever or frame G has a toe 201, shown by dotted lines Fig. 5, which acts against a lug 202 fixed with relation to the frame, and as stated, the lever is loosely mounted on the stud G. This loose mounting of the lever is of material advantage, for thereby it is possi-' ble to readily remove the said lever, and the hopper and its attached parts from the machine.

The operator to start the machine, puts his foot upon the treadle, lifts the rod 0 and causes the beveled upper end 0 thereof to close the clutch, and the said clutch will re main in firm engagement until the shaft 0 has been rotated sufficiently to perform its cycle of operations, for the teeth B of the rod acting on the toothed end of the three armed lever, of which the sleeve 13 forms the hub, moves the said lever instantly in a direction to remove the brake shoe from the brake wheel 0 and at the same time the roller stud B is moved away from the cam B so that as the latter starts it will not be held by the roll, but soon after the cam B starts the part thereof of greatest diameter acts on the roller stud and keeps the rod 0 fully elevated and the clutch pulleys in firm clutch until the depressed or lowest part of the said cam again arrives opposite the rod B In this way it is immaterial when the operator removes his foot from the treadle and releases the rod 0 during each rotation of the shaft 0 1 The teeth at the edge of the awl bar are so cut or made as to enable the head B to oscillate with the awl during the feeding movement thereof.

The lever armB and sector, constitute a locking device for the clutch rod 0 Having described my invention, what I claim and desire to secure by Letters Patent, 1s:

1. In a nailing machine, a driver-bar, a driver, a nose, and an awl-bar slotted transversely at its lower end to constitute an awlreceiving slot, and a clamp, combined with an awl adjustable in said slot toward and from the driver, substantially as described.
