WILLIAM L. OLOUSE, OF TIFFIN, OHIO.

WIRE-NAIL MACHINE.

SPECIFICATION forming part of Letters Patent No. 422,918, dated March 11, 1890.

Application filed June 24, 1889.

To all whom it may concern:

Be it known that 1, WILLIAM L. (house, a citizen of the United States, residing at Tiffin, in the county of Seneca and State of Ohio, have invented new and useful Improvements in lVire-Nail Machines, of which the following is a specification.

My invention relates to improvements in wire-nail machines, such machines as are designed for the making of plain orbarbed wire nails with large or small heads; and the objects of my improvements are to simplify the construction of machinery for that purpose,

to make machines that may be run at a higher speed and thus make nails faster, to construct machines the wearing parts of which can easily be replaced and adjusted, and also to construct machines by which, by the changing of dies and grip-jaws and the adjusting of the feed, several lengths of nails may be made of several diiferent gages of wire on the same machine. I attain these objects by the mechanism illustrated in the accompanying drawings, in which, standing in front of the machine-= Figure 1 is a left-hand-side side elevation of the machine. Fig. 2 is a right-hand-side side elevation of the machine. Fig. 3 is a top or plan view of the machine. Fig. 4 is a detail View of a part of the machine, showing one of the arms that carry the cutting and pointing dies, a part of which is represented in a section, which shows a horizontal longitudinal section of one of the cutting-dies with its pinion and wedge-rack for the adjustment of the cutting and pointing dies. Fig. 5 is a face view of the grip or heading dies-a detail of the machine. Fig. 6 is a detail horizontal section of the anvil-block, taken 011 the plane of the line of the machine, which is the line of the center of the wire when it is in the proper working position in the machine, showing the gripping-die on the one side and the die-block withits adjusting wedge and screws. Fig. 7 is a detail view showing the face of the jaws holding the cutting and pointing dies and the pivot of the same, also showing the picker and cleaner with its crank. movement. Fig. 8 is a detail sectional view showing the hinge or joint of the cutting and pointing die arms and the bearings of its pivot, also showing the cross-head or hammer-stock carrying Serial No. 315,445. (MotleL) the hammer. Figs. 9 and 10 are additional detailed views illustrating the construction of the die-block and its cooperating parts, 1n

all ofwhich views like letters refer to like The various operations performed by the machine in the making of a nail are performed by a single shaft O, arranged at the rear of the machine in suitable bearings for the same, and the operation of making a nail is c0111- pleted by a single revolution of the shaft 0. This shaft 0 is provided with a balance-wheel D and pulley D The different operations performed by the different movements of the machine While the shaft O is being turned one revolution are, first, straightening the wire; second, the feed which gives the length to the nail; third, gripping the wire to form the head of the nail; fourth, the movement of the hammer to form the head of the nail; fifth, the cutting and pointing, and, sixth, the movement of the picker and cleaner, which completes the round, and then the same is repeated at each revolution of the shaft while the machine is in motion and.,the wire fed into it.

The wire 10 passes between a series of groovefaced rollers m m, the two lines of which are adjusted to or from each other by means of the eccentric-headed levers Z l and their eccentric nuts or washers Z 1 against which they act, one of the roller-bars i being loose on the studs 25 23 c is a sliding feed-arm, which is fixed to the rod h, which slides in boxes on the bed frame or plate A, one arm of which slides on a bar 9 and is provided with 'a double pawl-dog g and 9 which holds the wire 10 firmly against a fixed j aw g on the feed-arm 0, thus causing the feed-arm c to move the wire forward and give the desired length for the nail by drawing the wire through the straightelling-rollers m m. The double pawl-dog has the pawl g pivoted to the feed-arm c and supported bya spring, and to the forward end of it is pivoted a smaller grip-dog g which bites on the wire 10 at an oblique angle by pressing it against a chisel-edge on the fixed jaw g 011 the feedarm 0. To the arm 0 a connecting-rod b is IO justing-wedge 2, and through the die-block F, which carries the grip-dies rand q. These grip-dies consist of an upper die 7', which is adjusted by a screw from above, and a movable die q below, which rests upon a push-pin I m This pin is adjusted by the screw Z in the lever H. Said lever H is pivoted at f, supported by a spring'and operated by the cam G on the shaft 0. The hook k is designed to draw the die q back and open the dies after the operation of heading the nail is performed. Said operation is as follows:

.07, is a hammer secured in a cross-head E, which works between the slides d and e, and is'driven by the pitman E which connects it with a crank on the shaft 0. (See Fig. 1.) By the operation of these parts the head is formed by actual pressure, which amounts to a blow by the rapid motion of the machine.

The operation of pointing the nail and 0 squaring the end of the wire to receive another head is accomplished by means of the double cranks on the shaft G, which operate the pitmen or arms I 1 one end of which is pivoted to or journaled onto the cranks of the 3 5 shaft 0, and the other ends are pivoted to the levers J 2 and M, which levers have aco nmon center pivot or shaft U, on which they move.

They extend out also on' the opposite side of the pivot U with a short arm, each of which 40 arms'is provided with knife-blocks K and N, each having a lateral and K a face adjustment, the face adjustment, or that in the line of the axis of the machine, being made by the wedge-rack'l and pinion n operated by the 4,5 pinion-bolt of, and, further, the collar-bolts O .0, as shown, are screwed into the arms, and are provided with collars which Work in a groove in the knife-blocks K and N and give to them a lateral adjustment.

The cutting dies or knives S are inserted in a dovetailed groove in the knife-block, and are held by set-screws g g and 4" r.

The -picker or cleaner consists of a bar Q, held near its inner end by a loop X to the arm 5 5 or lever M. The other end is pivoted to a bellcrank P, the pivot of which is secured to a bracket on the frame. The bell-crank P is also pivoted to a connecting-rod O, which receives a motion from its connection to the arm I on the crank-shaft O. A slight motion of the bar Q serves to remove the chips or the nails that may chance to stick in the cutting and pointing dies.

The bed-frame A is made of such a special 6 5 construction and shape as to especially adapt it for conveniently attaching the working parts, and especially for strength, compact- I believe to be new and claim as my invention.

The more minute and detail description of the machine is as follows: The bed-frame consistsof a lower horizontal plate, from which rises a vertical web or plate eXt-endmg lengthwise of themachine, from which extendout. cross-brace webs, which terminate above 111a double-curved plate, from which rise the boxes, bearings, lugs, anvil-block, &c.,' to

which the various working parts of the machine are attached." In the die-block F the upper edge is gained out to receive the lockplate X, which terminates in a bolt that passes through the anvil-block A and the lower edge of the die-block F terminates back in a ribbed bevel portion, to which the beveled gib-block X fits, which also terminates in a bolt that passes through The wedge 2 forms a' solid backing for the die-block F, andby the anvil block A means of the screw I) also forms a face adjustment for it, while the collar-bolt Y andplate Z form a lateral adjustment'for the dieblock F. The lower half of thegrip-dies .is; I

forced up to make the grip. by the push-pin m and is drawn back by the hook 10 the force being applied to the pin m -by means of the lever H, which is pivoted at f and is operated by the cam G on the shaft'C. The

thus allowing the roller in the end of the le-- ver H to travel on the face of the cam G on the shaft 0. ing of the dies, and the set-screw Z gives the required grip. V

The operation of cutting and pointing is accomplishedby the arrangement of double cranks on the shaft 0, to which are attached pitmen or arms I 1 which are attached also to the levers J and M, the angle at which the cranks are placed to each other being such that both cranks will center at right angles to their levers. I The levers J and M are hinged or pivoted on a common center in the form of a double box-hinge, as shown in Fig. 8, the lever J having two bearings and the The stop-bolt U limits the openlever M one. The shaft or pivot U is provided with an enlargement in the form of a collar to take up the lateral slack or looseness in the joint of the same. The heads or'shorter arms of the levers J 2 and M are arranged so as to attach to them the adjustable. knifeblocks K and N, in which the movable cutting and pointing dies are secured by setscrews. 7

The knife-blocks have two adjustmentsone in the line of the machine and a lateral adjustment. The one in the direction of the line of the axis of the machine is accomplished by means of the pinion-bolt and pinion n', working in the rack on the wedge 1 against the set-screw t. The lateral adjustment is made by the collar-bolt O, screwed into the arms of the levers J 2 and M, the collars working in grooves in the knife-blocks K and N, as shown in Fig. 7. i

The picker or cleaner, which performs the oifice of cleaning the dies of nails or chips that may stick to them, has in its parts a bar Q, a-portion of which near the end is turned up at a slight angle, which end in its movement traverses the space between the cuttingdies. Said bar is loosely held to the lower arm of the lever M by a loop X. The other end of the bar is connected to one arm of a is also pivoted to the arm I and receives its motion from the crank C. By the motion of the arm I the end of the bar Q receives a forward movement, and by its loop-connection X with the arm of the lever M it receives a downward movement, and the combinationof these two motions causes the end of the bar Q to describe a circular or elliptical path, according as the relativelengths of the arms producing the motions are changed to each other.

Having thus described and illustrated my invention in such a manner that one skilled in the arts could make and operate the same, what I claim as new, and desire to secure by Letters Patent, is-

1. In a wire-nail machine, a frame A, comprehending a lower horizontal base, from which rises a verticalweb plate extending lengthwise of the machine, from which extend out cross-brace web-plates,which vertical and web platcsterminate above in a doublecurved plate, from which rise the boxes, bear ings, lugs, anvil-block, &c., to which the va rious working parts of the machine are attached, as described and specified.
