WASHER FEEDING MACHINE Filed Aug. 19 1926 3 Sheets-Sheet 3 6 M 'm iom Patented Dec. 24, 1929 'UNITED STATES EDWARD B. CARTER, OF BOSTON, MASSACHUSETTS WASHER-FEEDING MACHINE Application filed August 19, 1926. Serial No. 130,120.

My present invention relates to apparatus or machines for handling and feeding washers, and more particularly to such machines adapted to feed washers to rubber heel gang molds.

In my prior Patent #1,590,030 issued June 22, 1926, I have illustrated one form of washer handling and feeding apparatus es-- pecially adapted for use in large factories, 1 but which, because of the expense of construction and other disadvantages, is not adaptable for use in smaller factories, such as shoe manufacturing or rubber heel manufacturing establishments.

In the rubber heel industry, it is desirable to have devices to supply or feed washers to the pins in a rubber heel gang mold, quickly and accurately, and at the same time to have a minimum number of machines to accommodate all sizes of heels to be manufactured.

It is a well known fact that the pins in rubber heel gang molds are out of line, to provide for the curvature of the heel. and also that some of the pins in a mold will be bent or staggered, rendering it difficult-to apply washers automatically thereto.

Therefore, an important object of my present invention is to provide apparatus for placing Washers upon the pins in a heel mold in a quick, eflicient, and accurate manner. In carrying out my present invention I have devised a portable washer feeding machine, adapted to hold a plurality of columns of washers, which machine is constructed and arranged to be wiped across a plurality of pins in heel.layouts in a gang mold. My novel machine is extremely compact 1n construction, the preferred form, when fully loaded with washers, weighing under five pounds. It will thus be seen that a machlne of this character, as light in weight as the present machine, can be easily operated, without fatigue to or strain on the operator.

A further feature of the present inventlon consists in a novel slice feed, which I have devised for use in the present machine, and which slice feed is automatically operated during passage over and contact with the pins in the mold. This shoe feed also acts as an automatic separating, feeding, and positioning means for the washers.

My present machine comprises a suitable base and frame, having supported on said base a plurality of arms or carriers pivotally mounted and spring fulcrumed, to permit simultaneous lateral and vertical oscillation; a plurality of wires or other supports, preferably locked in position at the top of the frame, depend therefrom and enter chambers. said chambers being carried by the pivoted arms. Each of the arms carries my novel slice feed device, automatically operable upon contact of the bottom of the carrier or arm with the pin. This slice feed arrangement comprises a bell crank lever pivotally mounted in the carrier, one end of the bell crank lever rocking in a shoe affixed to a sliding plate. The other end of the bell crank lever has a pin or rod which slides in a yoked arm.

Upon upward movement of the carrier, the bell crank lever will operate to slide the slice feed plate forwardly, separating the lowermost washer of the column, feeding it into position, with the aperture in the washer in position to engage the point of the pin to which it is to be fed. Guiding means are provided on the bottom of each carrier, to guide the pin into position under the washer to be fed thereto. and when the pin has reached this position the spring upon which the carrier arm is fulcrumed will force the carrier downwardly, firmly seating the washer upon its pin, retracting the slice feed plate and leaving the device in readiness for another operation. My novel apparatus is so constructed and arranged that it will operate efficiently in the slight space allowed between the pins of a mold. 'Also because of the lateral and vertical oscillation permitted, and the arrangement of the guiding means on the bottom of the carriers, one of these machines is enabled to supply a plurality of different- 1y sized molds.

The wires above-mentioned, for alining the washers, are suspended within the chambers a suflicient distance to allow or permit the passage of but one washer thereunder.

Further features of the invention, novel combinations of parts, and advantages, will be hereinafter more fully pointed out and claimed.

Referring to the drawings illustrating a preferred embodiment of my invention,

.Figs. 5, 6 and 7 are details illustrating the method of locking the wires at the top of the frame;

Fig. 8 is a longitudinal sectional view of one of the washer carriers in inoperative position;

Fig. 9 being a similar view in operating position, with a washer separated, fed out, and positioned to be placed on the washer p Fig. 10 is a front elevation of one of the washer carriers; and

Fig. 11 is a sectional view on the line 11-1] of Fig. 8.

As shown in the drawings, my present novel washering machine comprises a frame designated generally at 1, formed with a portion 2 to serve as a handle for drawing or wiping the machine across a mold. A plate 3 is preferably formed or cast integrally with the frame 1, and to this plate 3 is affixed a base or support 4. The machine is illustrated as traversing a mold 5, having a plurality of pins 6 formed in heel layouts, on which pins washers 7 are being and are to be positioned. The base 4has a longitudinal reinforcing strip 8 along each side, and centrally thereof is formed a guiding track or way 9, flared at its rearmost portion, as illustrated at 10, to engage pins which may be out of line; The pins in a heel mold, as set out in heel layouts, form three lines across the mold, and this guide 9 is adapted to engage the center row of pins. I

Provision for carrying the washers in the machine is made by having a plurality of wires 11, preferably three in number, although any desired number of wires from one up may be utilized. These wires and washers pass through flared recesses 12, in a laterally extending shelf or bracket 13, preferably formed as an integral part of the frame 1, which flared recesses 12 act as guiding and supporting means for the wires and washers, and permit free passage of the washers therethrough. A second laterally extending shelf 14 is provided or formed at the uppermost end of the frame 1, having therem recesses or apertures 15. The wires utilized formed with pointed heads 16, and have circumferential grooves 17 near their upper ends.

In order to provide means to hold these wires firmly in position, I have devised a novel locking means, which will insure firm holding of the washer carrying wires in the frame. Slots 18 lead from each of the recesses 15. Small plates 19 are positioned on the top of theshelf 14, projecting partially over the slots 18, said plates 19 having small notches 20 therein. With the plate 19 in position, sufficient space is left at the top of the slot 18 to allow for the passage of the grooved portion 17 of the wire only, Aside from the grooved portion 17, the wire is too thick to permit passage between the edge of the plate 19 and the opposite side of the groove. Therefore, when the wires 11 have been loaded with washers, the operator slides the top of the wire along the grooved portion 17 into the slot 18. Entering the slot 18, the

groove 17 engages a spring 21, which gives sufficiently to allow passage of the'wire, and when the wire 11 reaches the notch 20 the spring 21 will force the wire thereunto, thus firmly locking the wire in position, and preventing looseness or slipping thereof during operation. The plates 19are secured to the shelf 15 in anydesired manner, as by rivets 22 or the like. The springs 21 are curved, as clearly shown in Fig.5, one end 23 being preferably sunk in a small recess in the shelf 14, and the other end 24 being caught around a pin or the like 25.

The wires 11 are of suflicient length to hold a great number of washers, and, when the washers 7 are exhausted, the wires 11 can be readily refilled, without removal from the machine, by simply releasing the pointed end 16 from looking engagement, holding them centrally of the apertures 15 and reloading, by any suitable means. The wires would then be again looked as heretofore explalned, and the machine ready for further operation.

Pivotally mounted on the base 3 by means of pivot screws 26 are a plurality of arms 27 three being illustrated herein, and Figs. 8 and 9 being cross sectional details of one, which will suffice for all. Fixedly attached to the arm 27 by a screw or the like 28 is a spring 29. A. carrying arm 30 is secured to the spring 29 in any desirable manner, as herein shown by rivets or the like 31. The carrier 32 is affixedfo the carrier arm 30 by screws 33. The forward portion of the carrier 32 is formed as a chamber 34, having a flared upper end 35, to permit easy access of the washers 7 on the wires 11. As clearly illustrated in Figs. 8 and 9, the wires 11 when locked in position clear the bottom of the chamber 34 a sufficient distance to allow the passage of but one 'washer thereunder. A,

bellcrank lever 36 is mounted on a pivot 37 andhas one of its arms 38 yoked, with a pin 39 therebetween. This pin 39 fits in a slot 40 at the forward end of the arm 27. This arm 29, thus have provision for vertical oscillation, but no lateral reciprocation. The other end 41 of the bellerank lever fits in a recess 42 in a shoe 43, which shoe is set'in a sliding plate 44. The carrier 32 has a bottom plate 45 on which the plate 44 slides. Clearance is provided under the walls forming the chamber 34, for the passage of the slice feed or sliding plate 44.

Fig. 8 illustrates the Washer carrier and slice feed arrangement in normal position, forced downwardly by the tension of the spring 29, through recesses 46 in the base 4. At the front end of the chamber 34 a passage 47 is formed, preferably allowing the passage of but one washer at a time.

Formed on or secured to the bottom of the carrier 32, are guides 48, flaring outwardly at their rearmost portion, as clearly shown in Figs. 3 and 4 and leading to a slot 49 in the forward end of the plate 45. In passing over the mold 5, when the plate 45 comes in contact with a pin 6, as illustrated in Fig. 9, the entire carrier 32 is raised upwardly off the slanting seat 50 at the rear end of the recess 46 in the base 4, against the tension of the spring 29. The pin 39 being held between the jaws 40 of the arm 27, the end 41 of the bellcrank lever 36 is forced forwardly, pushing the shoe 43 and slice feed plate 44, also forwardly, separating the lowermost washer 51, for example, from the bottom of the column, feeding said washer forwardly, a suflicient distance to bring the recess 52 in said washer in alinement with the slot 49 in the plate45. The guides 48 will conduct the carrier over the pin 6 until the head 53 of the pin is in alinement with the slot 49. The machine is being constantly moved across the mold, and when the head 53 of the pin thus -enters the slot 49 in the plate 45, the entire carrier will drop, and be forced down by the tension of the spring 29, whereupon the washer 51 will be forced downwardly on to the head 53 of the pin, the head 53 entering the aperture or recess 52 in the washer. The carrier is now in position for contacting with the next pin in the row, whereupon this operation will be repeated. It will be appreciated that upon dropping of the carrier the bellcrank lever will be returned to normal position, together with the shoe 43 and slice feed plate 44, and that the column of washers in the chamber 34 will have dropped, leaving another in position to be engaged by the slice feed plate 44, separated from the column, fed forwardly, and positioned to be placed on a pin.

It will be appreciated that the middle carrier, as illustrated in bottom plan-view in Fig.3, will not require as great an amount of lateral reciprocation as the two outside carriers since the middle carrier follows the middle line of pins in the heel layouts, which line of pins is relatively straight. Some of these pins, however, may be slightly out of line, or bent one way or the other. Therefore, but a slight space has been left in the recess 46 for the center carrier, for such lateral oscillation as may be requisite.

It will thus be seen that I have devised an extremely compact, efiicient, and simple machine, economical of manufacture and requiring no skilled labor to operate same. The operator can shift from a mold using one size heel to another mold utilizing a larger or smaller size of heel layouts within a wide range of size, with this one machine. The machine requires no attention, except to reload or refill the wires 11 with washers, when the supply of washers thereon has been exhausted.

I believe that my novel machine is capable of use in many other fields than that of washer feeding, and therefore I do not wish to be limited, in the present application, to washer feeding, but have claimed the machine and operating parts broadly herein.

3 It will also be appreciated that while I have illustrated the present machine with three carriers, three reserve washer supporting or carrying wires, I am not limited to this number, but may construct the machine with but a single carrier and wire, or with any desired number. I may also substitute tubes for carrying the washers instead of the wires, within the province of the present invention.

The operation of the present device will be instantly apparent to those skilled in this art, and is as follows:

The machine being loaded with washers,

and ready for operation, the operator will position the machine on one slde or end of a gang mold, with the central pin, for example, of three rows of pins, entering the flaring end 10 of the central guide 9. The machine will then be wiped rapidly across the mold. As each pin comes in contact with the bottom plate 45 of the carrier, an upward movement thereof will be started. Coming into the guides 48 lateral reciprocation of the carrier will be effected, so that the pin will be directed into the slot 49. As the carrier moves upwardly, the bellcrank lever oscillates on its pivot 37, the end 41 rocking in the shoe 43 and moving the same forwardly together with the slice feed plate 44. The plate 44 engages the lowermost washer of the column, separates it therefrom, feeds it forwardly, and the washer is held in place by the remainder of the column and by resting on the forward end of the plate 45, until the pin head 53 enters the slot 49, whereupon the spring 29 will force the entire carrier downwardly, firmly and positively seating the washer 51, as shown in Fig. 9, on the head of the pin. The bell crank lever, shoe and plate 44 will instantly return to normal position, so that, no matter how slight a space may be between the pins,

eration of the machine.

. or a normal washer.

the machine will function rapidly enough to position a washer on every pm.

It will be appreciated that while I have necessarily described my present invention somewhat in detail, I may vary the size, shape, arrangement and number of parts, within wide limits without departing from the spirit of the invention.

.While I have illustrated conical washers as being utilized in instant machine, it will be apparent that the machine will function equally well with flat washers or other articles of various shapes,'which are desirable for use in certain classes or types of rubber heels. No change whatever in the mechanism of the machine is requisite to handle such fiat washers. Furthermore, slight variations or fluctuations in the sizes of washersflvhether conical, convex or fiat, will be immaterial, as the successful operation of the machine does" not depend upon having an absolutely or strictly standard size of washer or article.

I believe that it is entirely novel with me to have devised a machine or apparatus of the type illustrated and described herein, wherein a stack or stacks or articles are carried, and wherein the operating mechanism is automatically controlled and operated by the devices to which the articles are to be fed, or on which said articles are to be positioned, and I therefore include, in the present application, claims to this feature broadly.

My machine will function equally as well with high pins as with low pins, fluctuations or variations in the heights of these pins in various molds, not afiecting the successful op machine as illustrated in the drawings is constructed so that the late 45 will strike a pin, even if said pin is of the lowest type utilized. Thus the guides 48 and plate 45 will correctly position the washer carriers irrespective of the height of the pins or other devices, to

which the articles in the carrier are to be fed.

I also preferably utilize spring metal for the plate 45. and provide space thereunder, at the forward end, as clearly shown in Figs. 8,

9 and 10, to provide for a give downwardly of this plate 45 in the event that a thick washer should be presentedtothe slice feed arrangement. The spring plate 45, however, will be of suflicient rigidity to beunaffected by a thin However, if a thick Washeris at the lowermost part of the column, whenengaged by the slice feed plate 44, it would normally be prevented from passing from the carrier by the walls of the passage 47. However, pressure being exerted on the washer, the plate 45 will give sufiiciently to allow the passage of the washer. Thus it will be seen that in my novel machine I may use Washers of varying thickness, varying diameters, flat or convex, within wide ranges, with out affecting the successful and efficient flinctioning of the machine.

In other words, the

' loading wires used to transfer washers to the wires 11.

I do not wish to be limited, in the present application to the operation of my novel slice feed arrangement by contact with pinsor studs, or the like, as I may desire to utilize this slice feed in connection with other lines of work, wherein the slice feed would be automatically operated by means other than the work to which the articles fed are to be delivered.

Numerous applications of the utility of my novel machine will doubtless present themselves to those skilled in the arts.
