SPECIFICATION formingpart of; Letters Patent No. 562,597, dated June 23, 1896. Application filed January 16, 1896. Serial No. 575,717. (No model.)
ToaZZ whom it may concern:
Be it known that we, JOHN B. FLINT, of Ohelsea, in the county of Suffolk, and ARTHUR J. HOWARD, of Malden, in the county of Mid dlesex, State of Massachusettahave invented an Improvement in Nailing-Machines, of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on thedrawings representing like parts. i t t This invention has forits object to improve and simplify the construction of nailing-machines.
The machine here to be described makes its own nails from a fiat strip of metal, cutters, to be described, cutting away a portion of one edge of-the metal strip at intervals to form the tapering side of the nail and the under side of the head, the nail produced resembling a brad with a head projecting from one side of the body. i
Figure 1 represents a left-hand side elevation of a sufficient portion of our improved machine to enable the same to be understood; Fig. 2 is a front elevation thereof. Fig. 3 is an enlarged section in the line as, Fig. 2; Fig.
4, an enlarged view showing the inner or active end of the stationary nail-cutter and its carrier. Fig. 5 shows the cam detached; Fig. 6, the nail-cutter and movable carrier; Fig. 7, a detail of the pawlto operate the stripfeeding wheel; Fig. 8, a detail of the forked block. Fig. 9 shows the devices for adjusting the length of the nail, and Fig. 10 shows a nail such as will be produced in the machine.
The column A has a suitable foot, (not shown,) to rest on the floor, and it supports at its top the head A, which is of suitable shape to sustain the working parts.
The main shaft A has loose on it a drivingpulley Aihaving preferably a conical interior, which is adapted to fit against the conical face of a pulley A, fast on said shaft, the loose pulley being pressed in driving contact with.
the fast pulley by a wedge-fork A working against the beveled end ofa loose collar A the opposite end of which acts against the hub of the pulley A the wedge being attached to a rod A, connected in practice with a suitable treadle, the spring A acting normally to separate the said pulleys.
. its fulorumon the shaft O alongside the The pulley A has attached to, or forming part of it, a large wheel A herein shown as having aV-shaped groove in its periphery, which groove receives a wheel A having a A-shaped periphery, said wheel being fast on a shaft A carrying a grinding-wheel A The front end of the shaft A has attached to it a driver-lifting cam B, which acts on a lug of a collar B, fixed on the driver-bar B havingadriverB said cam lifting the bar, and a suitable spring 13 acting on a lever B to depress the said bar. The shaft A also has fast on it a disk B, (shown separatelyin Fig. 5,) said disk having at its front side a camgroove 13, (shown by full lines,) and at its rear side a cam groove B (Shown by dotted lines.) t
The cam-groove B receives a roller or other stud of a lever B, pivoted at B and having at its lower end a segmental toothed rack which engages the teeth of a pinion B fast on a short shaft O having at its outer end a pawl-carrying arm O, havingat its inner side a pawl O, pivoted at O and acted upon by a suitable spring O (see Fig. 7,) said pawl being normally acted upon by said spring to cause it to engage the teeth of a ratchetwheelO. This pawl has a constant throw, and the pawlwould consequently always have a definite stroke and would move the stripfeeding wheel 0 a definite distance, causing its acting against one edge of the strip a to feed always for a like distance, and the nails would all be of a certain length; but to enable the machine to make nails of any desired length this pawl has combined with it a shield 0 attached, as shown in Fig. 1, by screws to the end of a len gth-adj ustin g lever 0 having 9O ratchetwheel O and by moving this lever the shield may be interposed between the ratchet-wheel and the pawl, so that the effective stroke of the pawl in moving the ratchetwheel may be altered, as desired, to cause the strip to be fed for a greater or less distance, according to the length of nail desired. This lever is moved by hand and has a springactuated locking-pin G which cooperates with a toothed segment O fast on the machine-head, the locking-pin holding the lever in adjusted position.
The disk B has ratchet-teeth at its periphe. ery, which are engaged by a pawl 12 to prevent a suitable guide a and thence between the toothed feed-roll O and a cooperating roll a f mounted on a stud carried by a lever a pivoted at a and having combined with its end a pressure-ad j usting device, shown as a screw 5 a, the end of which abuts against the framework so that the effective pressure or force.
with which the said strip is grasped may be varied, and by using a narrow strip and feeding it by grasping its edges we find it possible to cause the teeth of the feed-wheel G to so embed themselves into the edge of the strip as to indent the same, leaving a series of scores or teeth, as a (see Fig. 10,) at the straight edge of the tapering-bodied nail, said scores or teeth adding very materially to the holding power of the nail. the feed-wheels the strip enters a guideway a (shown best in Fig. 4,) the said guideway be After passing below ing made from a steel block suitably grooved for the passage of the wire, the lower hard- I ened end of said guide terminating substantially flush with the shoulder a of aprojecting portion a of the framework.
b the said lip, in practice, traveling close under the shoulder a and acting with the hardened end of the guide a 'to cut the strip if to the shaft A The lever I) has upon it a loose block b, .1 kept in place by'a collar 5 and the said loose block is embraced by a forked block W, havtransversely into nail lengths.
ing a shank b, which is entered loosely into I a hole at the lower end of a lever Z7 pivoted at Z7 and having a roller or other stud Z9 at its upper end which enters the cam-groove b before described. The loose fork enables the 1 two levers b and b, one in a vertical and the other in a horizontal plane, to work freely.
The head of the machine has connected to i it by suitable screws 0- a plate 0, having a tubular nose 0 down through which the nail is driven by the driver into the work, the said nose resting on the work presented by the hand of the operator, usually the sole .of a shoe. sage in which is placed side by side a stationary cutter and a back or holding plate 0,
Above the plate a the head has a passaid plate being, however, adjustable longi; tudinall'y. The cutter c is held by a suitable screw, as 0 and the screw 0 enters by its inner end the plate 0 the hole in which the screw 0 stands being somewhat elongated to Patent, is-
being so moved as to place the said slots in line vertically with the guiding-slot at the lower end of the guide a the slots 12 b being at such time behind the face of the cutter c viewing the machine from the front side.
The grooves b and 6 having received the end of the strip, the lever 19 is moved, causing the strip to be cut off between the upper side of the lip Z7 and the lower end of guideway a and at the same time the portion of the strip in said grooves b and b especially the portion below the lip 6 is borne against and carried past the stationary cutter, causing the latter to clip or cut out from the edge of the strip a tapering piece, leaving a head of the full width of the strip and of a depth equal to the depth of the lip b and the lever b continues its movement in the direction in which it started until the grooves 17 and b arrive opposite the driving-groove 6, made in a steel block 6, held in place by a suitable screw e there being a space f above said block for the passage of the lip and the head of the nail over the end of the block in coming into line with the groove 6.
The block b is held in place by a suitable screw 6 and it constitutes the movable cutter member which cooperates with the stationary cutter member 0 and it also by its lip not only cuts off the strip, but also determines the shape of the head of the nail.
The bearing D, in which the shaft A turns, has a shank D which enters a hole in an ear D of the column, the shank being held in adjusted position by a set-screw D The bearing has a hole to receive a rod d, held in place by a set-screw D and inclined with relation This rod has mounted on it the hub of a blade-holder cl, having its upper side inclined from a horizontal plane and adapted to support the cutter-blade 0 The blade-holder has a lip d provided with a screwd to keep the blade seated, and screws (1 (1 act on the outer end of the blade to hold and adjust it.
The grinding-wheel is used to grind and keep the cutting edges of the blade sharp.
It will be noticed, viewing Fig. 4:, that the cutter c is set at an inclination to a vertical plane, so that it acts with a shearing cut on the strip, it meeting the strip first close to the under-side of the lip b and thereafter acting gradually to shear the metal to the point.
Having described our invention, what we claim as new, and desire to secure by Letters 1. Ina nailing-machine, the lever I) having a cutting-die provided with a lip, the said die and lip having coinciding grooves, and ablock having a driver-passage with a space above it for the head of a nail, combined with a guide for the strip being fed into the slots of the lip and cutting-die, and with a stationary cutter adapted to cut out'a portion of one edge of the strip and leave a head and a tapering edge below it, substantially as described.
2. In a nailing-machine, the shaft A its cani B a lever having a yoke provided with names to this specification in the presence of a shank held loosely in said lever, combined two subscribing Witnesses.
