MACHINE FOR CORRUG-ATING NAILS.
SPECIFICATION forming part of Letters PatentNo. 240,702, dated April 26, 1881. nppncauonfned embargo, leso. (No model.)
To all whom it may concern Beit known that I, HAYWARD A. HARVEY,`
of Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Corrugating Nails, of which thefollowing is a specication.
Theobject of my improvements is to provide an effective and convenientA machine for forming circumferential corrugations upon the bodies of nails, and particularly the kind of nails known as French nails.77 p v To this end my improvements consist in the combination with a rocking delivery-hopper, having a pi votalsupport,of a brush rotatingin said hopper and pulleys or wheels, one upon the shaft on which the `brush is journaled for driving said shaft and brush, and one coincident with thepivotal support of said hopper, whereby the nails in the hopper are prevented from crowding too forcibly against those being delivered from the hopper.
They also consist iu the combination, with corrugating-dies and ways or tracks whereby the nailsto be corrugatedare conveyed toward the corrugating-dies, of a curved chute for conveying the nails from the ways or tracks toward the corrugating-dies and properly pre senting them for entrance between the corrugating-dies.
In the accompanying drawings, Figure 1 is a front View of a machineembodying my improvements. Fig. 2 is a view of one side of the same. Fig. 3 isa View of the other side of the same. Fig. 4 is a transverse section of the delivery-hopper of the machine. Fig. 5 is an end or front view of the corrugating-dies and i adotted outline of the tracks or ways and the curved tube or chute. Fig. 6 is a detail View including a longitudinal section of a portion of the tracks or ways, and of the curved chute, anda side or face view of the corrugating-dies; and Fig. 7 is a plan of the corrugating-dies, the tracks or ways, the curved tube or chute, and other parts taken on a plane parallel with the axis of one of the corrugating-dies.
Similar letters ofreference designate corresponding parts in all the figures.
A B designa-te the corrugating-dies (see partcularly Fig. 5,) consisting, respectively, of a roll and segmental block, having their adjacent faces grooved or provided with ridges, l
whereby corrugations will be formed on the bodies of nails rolled between them. The nails to be corrugated are fed in at the upper end of the segmental block with their bodies between 4said block and the roll and their heads outside, and they are delivered from the lower end of the said block.
The roll A is supported on a rotary shaft, C, and the block B is preferably made adjustable, to canse the grooves or ridges on the block to converge more or less toward those of the roll from the upper to the lower end of said block, and thereby effect the corrugation of the nails gradually in their transit. As here shown, the said block is supported, about midway between its ends, bya stud, D, and is adjusted by means of rotary pins or studs E, provided with cams E', bearing against the exterior of the block, near its ends, the `said pins or studs E` being turned or rotated, by a wrench or otherwise, to cause the cam of either to force the adjacent portion of the block nearer to the roll. t
The shaft C, carrying the roll A, is mounted in bearings erected on a bed, H, (shown as supported on a pillar, G,) in an inclined position with the end adjacent to the said roll highest, wherefore the nails are not apt to fall out from between the block B andthe roll. The block B is supported on the end of the bed H adjacent to the said roll.
Having'described the nature and operation of the corrugating-dies, I will proceed to describe the means whereby the nails to be corrugated are fed and presented to them.
F designates a delivery-hopper, wherein the nails to `be corrugated are placed. They may be introduced directly into this hopper, or supplied in small quantities to it from a supplemental or supply hopper, G, mounted upon it. The hopper Fis shown as pivoted at one end to a standard, F', so that it can be rocked up and down to facilitate the delivery of the nails from it,'and a rocking motion is imparted to it by means of a rod, F2, connected to a wrist or crank, F3, on a wheel, F4, mounted on a counter-shaft, F5. This counter-shaft F5 is supported in an arm or bracket, F6, projecting from the pillar G', and may be driven in any suitable manner. In the hopper F, along the IOO bottom, is a groove or opening in which the bodies of the nails hang while supported by their heads resting on the sides of the hopper adjacent to the groove. The nails thus supported travel through the groove toward the lower end of the hopper, and are delivered thence to inclined tracks or ways I, which support them by the heads while their bodies hang down between said tracks or ways. The nails slide down these tracks or ways to the lower end thereof, as seen by the nails S in Fig. 7.
In the delivery-hopper F is a rotary-brush, J, of any suitable kind, supported on a shaft, J', so that at its lower portion it will brush or rub over the bottom of said hopper and against the nails which Aare in the hopper behind the brush but have not entered the groove therein. rllhe shaft J' is driven by a crossed belt passing from the counter-shaft F5 to a pulley on a shaft, K, supported by the standard F', at the point where the delivery-hopper F is pivoted to it, and by a belt from another pulley on the same shaft to a pulley on the said shaftJ', so that the lower portion of the brush J moves in the reverse direction to that in which the nails travel along the bottom of the deliveryhopper. The oliice of Vthis brush is to force back the nails in the hopper which have not entered the groove therein, and to preclude them from crowding down on the nails in the said groove, and to throw them back, so that they may enter the groove. The nails, on arriving near the lower end of the tracks or ways I, are delivered into a curved tube or chute, L, under control of a check of any approved form. The check I have shown consists of two bars,M M', passing transversely through the tracks or ways I, connected by a bridge-piece, M2, extending over said tracks or ways, and having a reciprocating motion imparted to them, whereby an inclined openingbetweentheirendsisintermittentlybrought opposite the opening between the tracks or ways, and allows the nails, one at a time, to pass between the bars. Owing to the opening between the bars being inclined, the nails are only allowed to move very slowly between them by gravitation, and hence are checked or precluded from passing too quickly and in too large quantities to the curved tube or chute L.
To the check-barM' is connected the upper end of a lever, N, pivoted at the lower end to the segmental or corrugating die B, and provided between its ends with an arm or lateral projection, N', carrying at its extremity a roller, N2. On the adjacent end of the shaft C is a B, with their heads outward, and they are thence pushed between said block and the roll A, whereupon the nails are operated upon by the block and roll.
O designates a reciprocating delivery-slide, working over the top of the segmental block or corrugating-die B and pushing the nails, as they' are delivered from the curved tube or chute L, into the space between the said block and the roll A. This delivery-slide is connected to one arm of an elbow-lever, P, which is pivoted to a stud on the bed H, and is actuated by pins Q on the back of the wheel C', so as to impart the requisite reciprocating motion to said delivery-slide. Preferably, the arm of the lever P, which is actuated by the pins Q, is jointed and has its two sections heldin their proper relative positions by a spring, P', so that in ease of any need the said arm may bend back withoutoperatin g the delivery-slide.
The shaft C of the machine may be driven in any suitable manner. I have shown it driven from a shaft, R, geared thereto and provided with suitable driving and idler pulleys.
What I 'claim as my invention, and desire to secure by Letters Patent, is-
1 The combination, with a rocking deliveryhopper having a pivotal support, of a brush rotating in said hopper, and pulleys or wheels, one for driving the shaft on which the brush is journaled and one coincident with the pivotal support of the said hopper, substantially as specied.
2. The combination, with corrugating-dies and ways or tracks, whereby the nails to be corrugated are conveyed toward the corrugating-dies, of a curved tube or chute for conveying the nails from the ways or tracks toward the corrugating-dies and presenting them in an approximately horizontal position for entrance between the corrugating-dies, substantially as specified.
