JOHN BERRY, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO THE NATIONAL NEEDLE COMPANY, OF SAME PLACE.

NEEDLE-MACHINE.

SPECIFICATION forming part of Letters.v Patent No. 404,337, uated May 28, 1889.

Application filed February 8, 1889. Serial No. 299,207. (No model.)

To all whom it may concern:

Be it known that I, JOHN BERRY, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Needle-Machines, of which the following; is a specication.

This invention relates to that class of needle-machines in which needle-blanks are automatically fed and presented one by one to the action of a clamping or ehucking device, which device then moves forward to carry the needle-blank to the action of devices or mechanism for performing the desired operation thereon, and for then withdrawing said blank from such mechanism and discharging same from the machine.

The object of the invention is to provide automatically-operating mechanism in needlemachines comprised in the class referred tosuch, for instance, as blank-swaging machines or needle-groovin g machines-whereby, at the time of the action directly upon the needleblank by the swaging-dies or grooving mechanism of the machine, the reciprocating movement of the needle-carrier will be comparatively slow, as necessarily required at such time; but at the time of the movement of the needle-carrier to withdraw the needle-blank from the mechanism for operating thereon, for receiving and clamping or chucking a new blank and carrying same forward to the essential operating mechanism, the movements of the needle-carrier will be accelerated, such latter movements, of course, occupying much less time than if their speed were uniform, the capacity of the machine being therefore greatly increased.

In the accompanying drawings this invention is illustrated and is shown as applied on and with relation to a needle-swaging machine, by the use of which pieces of wire cut into proper lengths for blanks from which to make sewing machine needles are successively and automatically fed to a position to be chucked by a carrier chuck or clamp, after which chucking they are carried to and forced' through' an opening in a separable swaging die-block, and the swaged and attenuated needle-blanks are then retired from the dies and discharged from the chuck and from the machine, and such machine and the operation thereof are fully described and shown in Letters Patent of the United States granted to me, dated November 22, 1881, numbered 249,822.

Figure 1 is a plan view and partial longitudinal section of the needle-swaging machine, substantially as illustrated in said Letters Patent, with the automatic mechanism of this invention applied thereon. Fig. 2 is a view in side elevation of the said improved mechanism and as much of the machine in connection with which it operates as will clearly show its operative connection and arrangement. Fig. 3 is an elevation at right angles to the one Fig. 2, as seen to the right of the line n: x. Fig. 4 is a sectional View in detail, as indicated by the line y y, Fig. 3, of a counter-shaft and fixed and loose pulleys thereon; and Fig. 5 is a plan and partial sectional View of a modified form of mechanism, to be hereinafter referred to.

The needle-blanks y are guided by the mechanism indicated at E', to be presented one by one to the clamping action of the chuck e, the movement of which chuck from its position shown in Fig. 1 is next forward to clamp the blank, then rearward, resuming its position shown in said Fig. 1, permitting the needle sustaining and guiding devices E to be moved laterally out of the line of travel of the chuck, when the needle is conveyed to and forced into the opening of the swagingdies c. The needle is then, by the chuck, Withdrawn to or about the said position shown in the drawings, being then ejected from the chuck, completing one operation of the machine. The needle supporting and guiding devices E are then rearwardly moved to the position shown, as the irst step of another operation.

11 represents the main shaft-of the machine,

on which is a driving-pulley, 13, and there.

are cams 10, 182, and g4, and weighted cords 14 19, which, through suitable connections with the main operatin g parts of the machine, impart thereto the movements mentioned, and all as fully described in said Letters Patent hereinbefore referred to, to which reference may be had.

A represents an overhead shafting, having IOO thereon for each needle-machine pulleys a and of large and small diameters; and l represents an overhead counter-shaft, having thereon for each needle-machine a iixed pulley, d, by which, through belt 7L, said pulley d and counter-shaft i3 are driven from the smaller pulley, a, at, comparatively speaking, a moderate rate of speed. A pulley, f, rotating on said counter-shaft loosely and independently thereof, is driven by the belt y from the larger pulley, l), on the driving-shaft A. Said loose pulley fhas an extended periphery, f2, ad jacent to which and of uniform size therewith is a pulley, (Z2, secured on the counter-shaft. A belt, i, passes around the driving-pulley 13 of the needle-machine and one or the other of the pulleys d2 or f2, and when the said belt fi is around the pulley d2 the machine is moving at its slower speed, but when the belt is around the pulley the speed of the machine is accelerated.

Mechanism for automatically eifcctin g the shifting of the belt /12 from the slow to the speedier pulleys d? f2, or vice versa, under my invention, is provided in needle-machines of the character hereinbefore mentioned, and consists, broadly, in providing a belt-shifter lever in proximity to the said fast and slow pulleys f2 d2, and providing` on a driving or driven shaft of the machine a cam for acting directly upon or through suitable interposed connections upon said belt-shifter lever for swinging it to effect the shifting of the belt.

As particularlyshown in the drawings, Figs. l, f3, and 3, the belt-shifter D is comprised in an angular lever intermediately pivoted in overhead han ger-lugs j, one leg thereof being bifureated, as at k, to embrace the belt, and to the other belt-shifter leg, Z, is secured one end of a vertical connecting-rod, an, to the other of which is connected one end of ahorizontal lever, n, intermediately pivoted on a lug, of the needleanachine frame, and said lever a bears by its free end upon the edge of a peripheral cam, q, on the driving and cam shaft ll of the needlc-blank-swaging machine, said lever being held to its cam-bearing by a spring suitably applied or its equivalent.

It will be noted with reference to the relative positions of the parts in Fig. l that they are in their positions for presenting necdleblanks and chucking same, at which period of the operation of the machine the lever nis in bearing on the least-extended portion' of the cam q and the belt-shifter caused to assume a position to place the belt upon the pulley f2 having the greatest speed, and until the parts have been moved and the needle carried to the swaging-dies such relation of the drivin gconnection is maintained; but i mmediately the needle by its end is brought to the dies, and before being further longitudinl lly moved thereinto, the cam q has turned to tilt by its extended edge the lever operating the belt-shifter, carrying the belt onto the slowly-driven pulley, whereupon the motion of the machine will be retarded, and will so continue on the slower speed during the swagin and atten uatin operation upon the blank, which being completed the accelerated speed is again resumed, and obviously the machine will be run at a maximum speed-as it is ca pable of doing without disadvantageous re sults-at alltimes except durin g the period of the actual swaging, and thus the capacity of the machine is increased to a considerable and important extent.

s, Fig. 2, represents a latch-arm pivoted by one end on the lever n, and adapted, when the lever is tilted to effect the retarded driving of the machine, to be swung to engage by iis bowed or hooked portion t the stationary horizontal brace-rod fu, confining the lever against tilting motion, and then the machine will be run at its slower specd,as in some classes of work may be deemed most desirable.

In the drawings, Fig. 5 is a plan view of a modiiied form of devices for carrying out the spirit of my invention for needle-machines, in which, as shown, the maiirshaft cam Q2 is an inclined-face cam on the side of a rotating disk, the lever n2 moving 'in a horizontal plane and extended into proximity with the Variablyspeeded pulleys d2 fl, having the belt-shifter legs k2 formed thereon, and thus intervening connections between the lever n2 'and the belt-shifter are unnecessary, such an arrangement being in many instances advantageous; but, to the end that an overhead disposition of the shafting may be made, it obviously is no departure from the invention to form the belt-shifter and the cam-actuated lever separately, interposing a connecting rod, as particularly shown in Figs. l, 2, and

In an application for Letters Patent of the United States iiled by me October 29, 1889, Serial No. 289,430, devices in accordance with my said invention as hereinbeforc recited are illustrated and claimed, as in an arrangement upon and with relation to specific parts of a needle-grooving machine, and on reference to the said description it will be appar ent that the present invention embraces within its scope the application of automatically-ol'ierating devices, in substance as de` scribed, upon machines for performing vari` ous operations on needle-blanks, whether swagin g, groovin g, or other work, wherein the needles are clamped and carried to the devices for directly operating thereon and then con veyed therefrom.
