MACHINE FOR FINI$H|NG HORSESHOE-NAILS.
SPECIFICATION forming part of Letters Patent No. 373,995, dated November 29. 8
Application filed May 14, 1885.
Be it known that I, WILLIAM W. MINER, residing at New Haven. in the county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Machines for Finishing Horseshoe-Nails, and I do declare the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in that class of automatic machines for finishing horseshoe-nails which embody condensing, beveling, and shearing devices and a carrier for presenting the nails to the same, the object of the present invention being to reduce the cost of building, maintaining in running order, and driving such machines by simplifying their condensing and beveling mechanisms.
With this object in view my invention con sists in a machine having a condensing-die rigidly secured to the bed of the machine, a roll, a carrier, and power connections inde pendent of the said die for effecting the liberation of the rolled nail from the rigid die and roll.
My invention further consists in a machine having a condensing die rigidly secured to the bed of the machine, a roll, a carrier, and power connections with such carrier to actu ate the same to advance the rolled nail beyond the rigid die before the idle stroke of the roll, which then passes between the rolled nail and the nail-blank next behind the same.
My invention further consists in certain details ofconstruction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan view of a machine embodying my invention; and Fig. 2 is a view thereof in vertical section through the stationary die and carrier, and showing the condensing-roll and its adjuncts in elevation.
As hereinshown, the die A is madein three parts and secured by a heavy plate or bar, 13, in a holder or anvil, 0, made solid to the bed D of the machine. The central part of the die is provided with a beveling-surface, E, and
Serial No.16 5,421. (Nomodel.)
setscrew, F, located in the said holder or anvil. The condensing-roll G isjournaled in an arm, H, having its lower end provided with a strap, I, encircling an eccentric, J, mounted upon a driving-shaft, K, and its upper end provided with a heavy spring, L, which prevents the arm from vibrating and holds it in position while being raised and lowered through the action of the eccentric. The said arm also carries an arm, M, pivotally mounted in it and carrying an anti-friction roll, N, engaging with the condensing-roll and traveling upon a permanently-rigid forming-die, O,
bolted to the bed of the machine, and shaped to determine the condensation of the nails and having its upper and lower ends cut away or retracted to permit the condensing-roll to drop back from the die at or near the limit of its up and down strokes.
The nails are brought between the die and the condeusing'roll by a ring-carrier, P, having bearing upon a suitable bed, Q, upon the inner face of which the spring aforesaid travels. The inner periphery of the carrier is provided with pockets R, receiving the nails. which are suspendedthrough their heads and held in place by the contiguous wall S of the bed Q, while its outer periphery is provided with ratchet-teeth T, as shown.
The carrier is operated and the nails liberated and prevented from being caught and held on the upstroke of the roll between the same and the stationary condensing-die by means of mechanism including with its connections a pawl, U, engaging with its ratchetteeth, pressed against the same by aspring, V, and fulcru med to a bearing, W, adjustable by set-screws X,
. driven by ash-aft, G, and constructed, adapted,
and timed to advance the carrier, through the lever and pawl, to carry the'rolled nail beyond the die and bring the opening between such rolled nail and the succeeding blank in line with the die and roll to permit the roll to be carried up through the opening and between the rolled nail and the blank, and then to advanee it again to bring the blank between the die and roll.
Having fully described a machine embodying my invention, I will now proceed to set forth the operation of such machine. Assuming the parts to be in the adjustment in which they are shown in the drawings, the rotation of the eccentric carries the condensing-roll down over the nail, against which it is pressed with great force, and which it condenses, flattens, elongates, and bevels. Then at or about the time the condensingroll reaches the limit of its active or down stroke it is permitted to drop back or retire by the lower retreating face of the former, whereby the rolled nail is released. The carrier is then advanced by its actuating mechanism, which is properly ti med with the action of the condensing-roll, and the rolled nail carried beyond the d ie.and the opening between such rolled nail and the succeeding blank brought in line with the (lie and the roll. Then the roll is carried up through the opening and between the rolled nail and the blank, and at or about the time it reaches the limit of its idle or tip-stroke it is permitted, by the upper retreating face ofthe former, to drop back from the die, whereby an opening between it and the same is formed. Then the carrier is advanced again to bring the blank between the die and roll, and the operation described is repeated. It will thus be seen that in the machine herein shown and described the rolled.
nail is liberated and prevented from being caught and held on the upstroke of the roll between the same and the stationary condensingdie by advancing it beyond the die before the upstroke of the condensing-roll, which is carried up through the opening between the rolled nail and the succeeding blank. By liberating the rolled nail in this manner I am enabled to employ a stationary die and to avoid the expense of building, maintaining in running or der, and driving the heavy mechanism heretofore employed for reciprocating the die to retire the same and prevent the nail from being caught and held between it and the roll, which, in machines employing reciprocating dies, makes its upstroke before the carrier ad van ees and over the rolled nail, which is then carried forward by the movement of the carrier.
I would have it understood that my invention comprehends, broadly, the use of a sta tionary die in conjunction with a condensingroll, a carrier, and means for liberating the rolled nails. The means for liberating the rolled nails may, for instance, take the form of mechanism for retiring the condensing-roll. I would therefore, and further, haveit understood that I do not limit myself to the exact construction and arrangement of parts herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
1 am aware that it is old in the class of machines to which this invention relates to employ movable dies retiring for the liberation of the rolled nail, and to block such dies during the rolling operation.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a machine for finishing horseshoenails, the combination, with two permanentlyrigid dies placed opposite each other, of a nail-roll operating between such dies, and a carrier for bringing the nails between the dies, where they are condensed by the roll, substantially as set forth.
2. In a machine for finishing horseshoenails, the combination, with two permanentlyrigid dies placed opposite each other, of a nail-roll operating between such dies, a nailcarrier, and suitable power connections with the carrier to actuate the same to advance the rolled nail before the idle stroke of the roll, which then passes between the rolled nail and the nail-blank behind it, substantially as set forth.
3. In a machine for finishing horseshoenails, the combination, with a condensing-die rigidly secured to the bed of the machine, of a roll, a ring-carrier having its periphery provided with teeth, a pawl engaging with such teeth, a pawl carrier for carrying the pawl, and a cam for actuating the pawl-carrier, the said pawl, pawl-carrier, and cam being constructed and timed to actuate the ringearrier to advance the rolled nail beyond the die before the idle stroke of the roll, which blank next behind it, and then again to bring such blank between the die and roll for condensation, substantially as set forth.
In testimony whereof I have signed. this specification in the presence of two subscribing witnesses.
IVILLIAM \V. MINER.
