MACHINE FOR FEEDINGIBLANKS To LATHES.

SPECIFICATION forming part of Letters Patent No. 317,601, dated May 12, 1885,

Application filed June .25, 1884.

]a bevel-gear, b, on one end, and this gear meshes with a gear, I), on the shaft B To'aZZ whom it may concern:

Be it known that I, JOSEPH \VELKER, J12,

of Central Falls, in the county of Providence and State of Rhode Island, have invented a 5 new and useful Improvement in Machines for Feeding Blanks to GageLathes; and I do hereby declare the following specification,

taken in connection with the accompanying drawings, forming a part of the same, to be a description thereof.

This invention relates to a machine for feeding spool or other blanks to a gage-lathe to be turned; and it consists in certain features of construction, as hereinafter described I and set forth in the claims. f

Referring to the drawings, Figure 1 repre= sents a top view of a machine embodying the invention, and a gagelathe with which the said maohine can'be combined. Fig. 2shows a side view and partial section of the machine and the lathe. Fig. 3 represents an end view of the machine with the hopper for holding the blanks in section. Figs. 4, 5, and 6, show several parts of the machine in certain positions. Fig. 7 represents an end view of the lower part of the conveyer, or chute.

The machine is provided with ahopper, A, for holding a mass of blanks which have preferably been bored with substantially central 0 holes and have been roughed into the shape of cylinders.

For convenience in introducing the blanks into the hopper, and in order that alarge supply of blanks may be furnished, the hopper is preferably provided with an inclined extension, A. The sides of the hopper are preferably made to converge laterallyat the bottom, as shown in Fig. 2, in order that the blanks shall seek the lowest plane, and the 40 hopper is preferably provided with a central groove, (1, of a width slightly greater than the diameter of a blank, in order that the blanks may lie lengthwise therein.

For removing the blanks from the hopper, a roulette, B, is employed, which is composed of arms, b, each having near its outer end a spur, b, of a diameter adapted to enter the bore of a blank, although in place of these spurs, scoops or spring-fingers may be secured to the arms I) to take up the blanks. The roulette B is mounted on a shaft, 13, which has (No model.)

This shaft is provided with a pulley, b", which is driven by a belt from any convenient source of power, as a counter-shaft, or from a pulley, c, on the main shaft of the lathe O, as shown. in Fig. 1. The roulette is revolved in the direction of the arrow, Figs. 3 and 4, and

as the outer ends of its arms pass through the groove a the spurs b enter the holes in the blanks lying therein and take up the blanks D, as shownin Fig. i. V

For receiving the blanks from the roulette and carrying them toward the lathe, an inclined conveyer or chute, E, is furnished, {which is pivoted or otherwise secure'dto a standard on the frame of the machine, as shown in Figs. 2, 3, and 6. Attached to the upper end of the eonveyer E are two ways, e 6., Fig. 1, which are separated by a space sufficient to allow the arms of the roulette B to pass between them.

For removing the blanks from the arms of the roulette, a pawl or stripper, F, is em- 7 5 ployed, which is pivoted to an arm, F. This arm is pivoted to a stud, f, and has a projection or roller, f, which enters a slot in a cam, F mounted on the shaft 13 the said cam acting to reciprocate the pawl or stripper F.

For guiding the pawl inits movements, one of the ways, as e, is preferably furnished with an upwardly-projecting flange, e upon which rides a roller, f secured tolthe side of the pawl v at its outer end. This end of the pawl is prefer- S5 ably supplied with a )ivotedfinger, f which, as the pawl is moved outwardly, rides over the blank on an arm of the roulette, and falls behind the blank, as shown in Fig. 4. By the-action of the cam F" the pawl F is advanced or moved inwardly to strip a blank from an arm, I), ofthe roulette and pull the blank along the ways 0 e to a position in front of the upper end of the eonveyer E, as shown in Figs. 2 and 3. In order to guard a blank being carried by its momentum (when the machine is run at high speed) beyond the properpost. tion on the ways where it should be left by the pawl F, springs f*, Figs. 1 and 5, or other suitable means, are preferably employed to create friction upon the blank as it is moved along the ways.

The blank is removed from the ways into the conveyer Eby a second pawl, G, Figs. 2 and 5, which is pivoted to an arm, G. This arm is pivoted to a stud, g, Fig. 5,,and bears a projection or roller, which is held in engagement with a can], G Figs. 1 and 5, on the shaft B by-a spring, gZFigs. 1 and- 5. \Vhen the blank is left by the pawl F in the position described, the pawl G has been moved to the position shown in Fig. 2. The cam G2 now acts to advancethe pawl G and cause it to remove the blank from theways into the conveyer, as shownin Fig. 5, down which the blank rolls, andfalls on ledges e e projeeting inwardly from the conveyer sides, as shown in Figs. 2 and 7. The movements ofthe pawls F and G are sotimed with relation to the movement of the roulette B that as each arm b of the latter brings up a blank the said pawls, remove the blanks from the arms to the conveyer.

As some of the arms I) may occasionally fail to pick up a blank provision is made for keeping the, conveyer supplied with blanks by revolving the roulette at a greater speed than would be necessary should each arm always take up a blank; and as each of the arms I) may take up blanks for some time continuously, it is necessary that provision be made for the escape from the, ways e e of such blanks as cannot enter the eonveyer should it be full. If the conveyer be full at a time when a fresh blank is moved toward itby the pawl G, the uppermost blank in the conveyer will prevent the entrance of such fresh blank, which will roll back into the ways e e'when the pawl retreats. As shown in Figs. 1 and 3, the rear ends of the ways are connected by a bridge, e", and this bridge is arched sufficiently to allow a blank to pass under it,'so that as a second fresh blank is brought along the ways by the pawl F, the rejected blank lying in the ways can be, pushed by the advancing blank under the bridge and out ofthe ways, when it will fall nintojthe hopper A. If preferred, however, the rear ends ofthe ways beyond the conveyer may be sufficiently separated laterally to allow a rejected blank to drop through between them when it is pushed along as ,described. a

Since an attempt to introduce a fresh blank into theconveyer at a time when it is full wouldtend to force ,upout'of line onelor more blanks lying in, the conveyer, the sidesof the latter are preferablyprovided with attached innervbars orsuitable'fianges, 636?, which overlie the, ends of the blanks and preventthem from being forced upward, although a single bar may be employed to overlie the blanks.

for such purpose, if desired.

From. the ledgesa'a, the blank is removedto betnrnedto the lathe-centers 0' a and, for this pliflPOSQ, any suitable carrier, may be e111- ployed. The carrier-shown in. the drawings consists of two fingers, HHL The finger H has a notch in its front end for engaging the blank, and is arranged to slide on the standard H. The finger H is pivoted to an arm, h, which is adjustably secured to a-stud, h projecting, downwardly from the finger H, as shown in Figs..2 and 6, and a spring, h, is employed for causing the finger H to hold the blank against the notched end of the finger H during the movement of the blank by said fingers. Vhen the blank falls upon the ledges e the fingers H H are in a rearward position, as shownin Fig. 2, and to allow the blank to enter between them a stop-rod, h, secured to the standard H is used to hold the upper end of the finger H slightly advanced. To the finger H a link, 71 is pivoted, which link is connected to thelong arm of a bell-crank lever, I, the short arm of which bears a projection or a roller which enters a slot in the side of a carn', l, on the shaft 132, Fig. 6, the said cam acting to reciprocate said finger. The Cam I, however, may be located on a shaft on the lathe G, if desired, and a suitable bellerank lever and, link be employed to cause the cam to reciprocate the fingers H H, as will be readily understood. As the fingers H H move forward under the action of the cam I, the fin-1 ger H leaves the stop-rod if and is closed by the spring h against the front of the blank, thereby firmly holding the same in the notched end of the finger I-I. During the advance of the fingers the lowermostblank in the conveyer E is prevented from falling by the finger H, which actsas a cut-off and supports such blank, as shown in Fig. 6. The cam I advances the fingers H Huntil the bore of the blank held by said fingers is in alignment with -theilathe-centers c 0 when the former center is moved forward by suitable means to enter the bore of the blank and force the blank upon the live-center a, which revolves. the blank, in order that a tool, 0, on the lathe C may turn the blank to the desired shape. The center 0 having moved forward to take the blank, the fingers are retracted to the position shownin Fig. 2, to take a fresh blank. As the fingers move rearward, the finger H is turned on its. pivot by the blank, so as to clear the latter, the spring h at its point of attachment to said finger passing below said pivot and holdi-ngthe finger open. During the retreat of thefingers to their rearward position the curved end of the finger H engages a stop-rod, hf, which turns the finger back to its normal position. If desired, however, the rod h? may be dispensed with and the finger H be pivoted to the arm h ata point sufficiently below the point where -the spring h is attached to said finger :to cause said spring to return the finger to its normal position when it clears the blank, as willbe readily understood.

In order to prevent a. blank from being crushed or injured, and the finger mechanism from being damaged,:shonld a blank be accidentally caught: on. the upper .pointvof the notched. endof the .fingerH, the conveyer E is preferably provided with pivoted springlatches e e, which will swing outward under tain limits, the sides of the hopper A are preferably made adjustable laterally,and are held in a proper relation to each other by suitable means, such as bolts and nuts J 9, Figs. land 3.

For conveniently adjusting the hopper sides their 'feet A are preferably mounted to slide on rods or bearings K, and a right and left hand screw, L, is employed to move said sides laterally with relation to each other, the said screw being furnished with collars l, which bear against a stud, m, on the base M, Figs. 2 and 3. Byloosening the nutsjand turning the screw L in the proper direction the hoppersides can be made to approach or to recede from each other, thereby narrowing or widening the groove a, according to the diameter of the blanks to be fed. As shown in Fig. 2, the

' bottom of the groove a is made substantially V shape, so that when the groove is widened to admit blanks of larger diameter, or narrowed for blanks of smaller diameter, such blanks, respectively, will occupy a lower or a higher plane on the doubly-inclined bottom of l the groove, thereby bringing the bores of the blanks into proper position to receive the spurs b on the arms of the roulette. If desired, however, instead of making the hopper sides adjustable laterally, or in addition thereto, the arms I) of the roulette may be adj ustaable lengthwise, so as to bring the spurs 1) into proper positions to take up the blanks, as will be readilyunderstood. The bars 6 on the conveyer E are also preferably made adjustaable vertically, to accommodate blanks of different diameters, the said bars being secured to the conveyer sides by thumb-screws a, Fig. 1, or other suitable means.

In order to allow the conveyer E to receive blanks of different lengths one of its sides, e,

is preferably made laterally adjustable with relation to the other side. For this purpose .the side 8 is provided with slotted lugs 6 Fig. 1, which are secured by thumb-screws or other suitable means, a, to lugs c", Fig; 3,

projecting from the conveyer-bottom. The

ledges e c on the conveyer are also preferably made vertically adjustable to receive blanks of different diameters, so that the axes of the blanks shall be in a proper relation to the notched end of the finger H, the said ledges being secured to the sides of the conveyer by thumb-screws 12?, Fig. 7.

Although I prefer to employ the pawl G to remove the blanks from the ways e e to the conveyer E, yet, if desired, the said pawl may be dispensed with, and the upper end of the conveyer be located in such relation to the ways that when the blanks are moved by the stripper F to a position in front of the conveyer they will roll into the latter by their own gravity, as will be readily understood.

Preferably the conveyer E is pivoted to its supporting-standard or is otherwise mounted,

so that its upper end, or both of its ends, are vertically adjustable, so that it can be brought into proper relation to the roulette to receive therefrom blanks of any size.
