NAILING APPARATUS.

SPECIFICATION forming part Of Letters Patent'No. 695,385, datedMarch 11, 1902.

Application filed December 17, 1900. Serial No. 40,080. (No model.)

drawings, is a specification, like characters on the drawings representing like parts.

In another application, Serial No. 3%,877, filed October 30, 1900, I have shown and described a nailing apparatus having a hopper which may be rotatedwhile thedriver is inoperative to load the raceway with tacks.

The invention to be herein described is intended to be an improvement on' theappa ratus shown in said application.

One feature of invention herein contained is a provision for stopping or starting the shaft carrying the pinion employed to rotate the hopper, I using, as herein shown for such purpose,.a clutch. I have also produced a novel pick-0E and stop, it presenting double points to better control tliem'ailor tack. I have also devised a novel clearer'to dislodge any nails or tacks improperly deposited upon the raceway.

Figure 1,in side elevation, represents a nailing-machine hung up in its inoperative position that its raceway may be filled. Fig. 2 is a view looking at the hanger and'its driving mechanism from the left, Fig. 1. Fig. 3 isa section through the apparatus, raceway, and

hopper. Fig. 3 is a detail of the upper end of the raceway. Fig.4. is a detail showing the pick-off, nose, and driver in one of its positions. Figs. 5 and 6 show the pick-0E from its side nearest the end of the raceway and the nose, the pick-0E being in different positions. Fig. 'Zshows the pick-off in perspective; and Fig.8 is a section in the line a, Fig. 3.

The frame or hand pieceA presentsa tube having an extension A, which may be provided, as shown, with a stud A, which may enter notchesof a bracket or wall piece 13, adapted to be secured to any suitable support, as a wall, by a screw. The extension also serves to sustain the hraceway C and hopper G, to be described. The tubular part of the frame contains a bearing a for adriverbar a havin' a driver a said driving-bar having at its upper end a shouldered head a provided with a depeiiding tube (1. which, as shown, enters 'the tub ular part of the frame. A spring a resting at one end on the hearing a and acting at itsother end against the head, keeps th e'driver bar normally in its inoperative position; The extent of movement of the bar a by the spring a is controlled by a stop a which enters a slot a in the bar. The driver-bar hasat its lower end a finger a which at each descent of said bar meetsa roller or other stud e of a slide E, a suitable spring,v as 9', moving the said slide in the 0pposite direction.

The nose D, inserted in the lowervend of the tube A, is grooved transversely to sustain and guide the substantially U-shaped slide E in its movements, and said nose is also notchedto' sustain the'llo'wer end of the raceway G, as shown in Fig. 3. The lower end of the raceway enters the open. space e between the arms of the slide, and the groove of the said rac'eway,in which hang the bodies of the nails, is in line with a slot in the side of the nose, that nails may enter the nail-passage d in said nose.- InOrder that the nails may enter the nose singly who acted upon by the driver, eacharm of the slide is provided with two prongs, the said prongs constituting two pairs of oppositelydisposed prongs ,facing each other, each arm of tge T e said prongs are separated to leave a diagonal space between the contiguous ends of each pair through which each nail taken from the end of the raceway by said prongs passes on its :way into the driver-passage; By the employment of the lower pair of prongs e e it becomes possible to control and'position .the point 'or lower end of the nail, whatever its length, and prevent 'it from tipping on the upper side of the prongs 6 e sothat the point of said nail will meet the nose in the bottom of the slot therein through which the nail enters the nose. The nose has a vertical slot d in which is pivoted a nail-supporting device d acted upon by a spring dfiwhich normally keeps the hooked lower end of said device in position to arrest each nail picked off the raceway by the slide E until said nail I is struck by the driver. The raceway, composed of a bar having a suitable slot or groove, is held in place by suitable screws 0, other screws a holding in place the cover c in usual manner. The upper end of the raceway entering the hopper G has a wing c, on which the nails lifted by the shelves g of the hopper drop, the points of the nails entering the groove of the raceway, while the heads of the nails are sustained thereby. The inner end of the hopper has a flange g, which enters a circular groove between a ring 9 and a circular plate g preferably forming a part of the frame'casting. The inner or left-hand side (see Fig. 3) of said ring and casting has also, as shown, a circular guideway or groove, which, as shown, receives a series of carriageblocks 9 connected with said hopper by suitable screws g said carriage-blocks and the end of said hopper traveling in said circular grooves as the hopper is rotated. By supporting the foot of the hopper at one end in a circular groove I obviate the employment of a shaft extended centrally through the hopper, and the space inside the hopper is less obstructed, enabling the diameter of the hopper to be reduced. The hopper has connected with it by suitable screws a toothed ring 9 The right-hand end of the hopper is provided with a door g sustained by suitable hinges g. The casting g has pivoted to it at h a clearer h, shown as a spring'controlled lever having its upper end inclined (see Fig. 8) to be struck by a series of rollers or other studs on, carried by screws m, inserted in the flange g, the lower curved end of said clearer eX- tending transversely to the raceway and being vibrated opposite the stress of the spring 2 and occupying always a position above the racewayjust above the upper end of the cover, the clearer acting as a gage to enable the heads of nails properly seated in said raceway to descend and by its curved lower end removing from the raceway any nails or tacks lodged thereon improperly.

To prevent a nail lodged crosswise on the raceway from entering the space between the under side of the clearer, occupying always a position over the raceway, and the top of the raceway, I have erected on the side of the race way a stop 10, (see Fig. 3, full lines, and Fig. 3, dotted lines,) the upper end of said stop extending above said raceway and arresting such nails.

The clearer, in order that it may operate properly and not be subjected to lateral strain to thereby bind the clearer on or strain the pivot h, is guided at its lower end by means of a stud m the shank of which is extended through a slot in the plate g and enters the clearer, the head of the stud moving close to the said plate. By extending the head of the clearer through the slot in the plate 9 the said clearer may be manually vibrated by means of the stud 012 should the said clearer stick or get caught.

hen the operator commences to use the apparatus, he holding it in one hand, the raceway is supposed to be filled up with nails or tacks, and while the apparatus is used in driving nails the hopper is usually at rest.

\Vhen the apparatus is not being used, as when, for instance, a workman is preparing a shoe to receive nails or tacks for lasting or for other purpose, the workman hangs the frame upon the bracket B, as in Fig. 1, so that the toothed ring g is put in mesh with the pinion H on a shaft H, having its hearing in said bracketand provided at its opposite end with a bevel-gear H which is engaged and driven by a bevel-gear H on a main shaft H provided, as herein shown, with a belt-wheel J, loose thereon, and provided with a stud 3, forming part of a clutch, the other part being a stud 4, carried by a block J, having a pin 5, entering loosely a slot 6 in the shaft H By the employment of this clutch it is possible when in the position Fig. 2, the clutch being separated, to enable the pulley J to be run, it being driven by a belt (not shown) actuated by a pulley from any usual connter-shaft without rotating the shaft 11 and the hopper. When it is desired to rotate the hopper to fill the raceway, the clutch will. be made operative by sliding the hub J toward the hub of the pulley, and whenever the raceway has been filled the clutch will be opened and the further rotation of the hopper be stopped.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1's

1. In a nailing-machine, a raceway, a hopper, a loosely-pivoted clearer inside the hop per, means carried by said hopper to vibrate the clearer transversely of the raceway, a headed guide-pin connected to the clearer and projecting through a slot in the hopper, the head of said pin engaging the outside of the hopper and serving to maintain the clearer in its operative position.
