WASHER OR BUTTON FEEDING ATTACMENT FOR SETTING-MACHINES.

Specification of Letters Patent.

Patented June 15, 1909.

Application filed June 17, 1908. Serial No. 438,917.

To all whom it may concern:

Be it known that I, SIMON GRossMAN, a; citizen of the United States, and a resident of the city of Pittsburg, county of Allc gheny, and State of Pennsylvania, have invented a new and useful Washer or Button Feeding Attachment for Setting-Machines, of which the following is a specification.

My present invention relates to a portable attachment which can be readily applied to existing setting machines for the purpose of providing said machines with an automatic feed for washers, buttons or other component part of a fastener device, thereby to greatly increase the efficiency and quantity of output of machines where the washer or other feed is by hand.

In the drawings which show only one of the forms which my invention may take, Figure l is a view of a post-setting machine showing my attachment applied thereto; Fig. 2 is a side elevation partly in vertical section of my attachment omitting the depending connecting parts to the treadle and showing in dotted lines the post of the machine; Fig. 3 is the same except that the parts are shown in another phase of their relative movement and the machine post is omitted; Fig. 4 is a view of a detail; and

Fig. 5 is a top plan view as seen from above in Fig. 3.

Describing now my invention with particular reference to the devices of the drawings, my attachmentis shown in connection with a setting machine which, forming no part of my present invention except that my attachment is adapted to be used in connection with a setting machine of some sort where the washer or other feed is by hand, will need no detailed description and consequently has been shown merely in outline in the drawings. However enough has been shown of the setting machine to indicate its base 1, pillar 2, arm 3, head 1, treadle 5, and operating levers 6. After removing the lower set from such a machine, an opening is left suitable to receive a downward projecting stud 7 from the head of the attachment to center said attachment on the setting machine and secure it against lateral displacement.

The head 31 of my attachment in that portion 8 which is immediately over the stud 7 constitutes the set or anvil to receive against it and upset the end of the rivet shank fed from above in usual manner by the head of the settlng machine. This anvil or set 8 1n the part1eular form shown has a central elevation adapted especially to spread the prongs of a bifurcated, or the shank of a hollow tubular rivet. However it will be understood that of course this is an immaterial feature which will depend upon the nature of the fastener part fed from the head of the setting machine.

The particular form of my feeding attachment shown is illustrated in connection with washers and in the annexed description the device will be described in connection with washers, although it will be understood that the invention is equally applicable with or without immaterial modification to feeding buttons and other articles and it is herein intended to be so claimed.

In the top of the head 4 is a depressed guide-way 9 adapted to receive the washer fiatwise and permit it to be pushed along until it occupies a position immediately over the anvil, whereby the shank of the rivet fed by the rivet head can be passed down through the washer opening into contact with the anvil to be upset against the underside of the washer.

At the sides of the washer guide-way in the particular device shown are undercut guides 10 adapted to receive between them the correspondingly beveled side-edges of a cover-plate 11 adapted to be manually moved into and out of position between said undercut guides. Said cover-plate when in position leaves an intervening space between itself and the bottom of the washer guideway, somewhat greater than the thickness of the washer, sothat the washer can be freely progressed under it.

For the purpose of so progressing the washer, a push-member 12 is located in the washer guide-way adapted to have its end contact with the edge of a washer in said guide-way to push it toward the anvil. The means for automatically operating said push member from the machine treadle will be described hereafter.

The means for delivering the washers up into the washer guide-way so that member 12 can push them one at a time to the anvil, comprises a tube 13 adapted to hold the washers in a pile, said tube opening at its top into the bottom of the washer guide-way in the head. and containing a follower 1st spring-pressed from below by spiral spring 15 to give the washers a normal upward tendency, whereby the topmost washer is forced up against the bottom of the cover 11 and so occupies the washer guide-way in the path of the push member 12, whenever said member on its return reciprocation uncovers the tube opening.

The follower 14 has attached to it a depending chain 16 which comes out through an opening in the bottom of the magazine tube and which can be pulled downwardly and held, to control the spring 15 topermit filling the magazine with washers said filling being conveniently accomplished through the delivery end of the magazine by withdrawing the sliding cover 11 and also the push member 12 so as to uncover and give access to the mouth of the magazine.

The means for automatically operating the push member to deliver a washer at each stroke of the machine comprises operative connections as follows. Thus the rear end of the push member has a socket 17 into which extends the. free end of the member 18, pivotal ly supported from the magazine tube to adapt it to be moved to and away from said tube to reciprocate the push member in the washer guide-way. A spring 19 located between the pivot arm 18 and the magazine tube gives said arm a normal tendency to collapse against the magazine tube and to carry the push member toward the anvil end of the head to deliver a washer to said anvil.

To bring about the return reciprocation of the push member, a sleeve 20 is provided having a sliding fit up and down on the magazine tube and carrying at one side a yoke 21. adapted to slidably engage the pivot arm 18, whereby when said sleeve is in its uppermost position said arm can occupy a position in which the push member is in its innermost feeding position, whereas depressing said sleeve naturally causes the return reciprocation of the push member due to the fact that the sleeve engages the pivot rod nearer its pivot connection with the magazine tube.

Projecting from the side of the sleeve 20 is a pivot-pin 22 connected by link 23 with connecting rod or rods 24, the other end of the latter being secured to a U shaped clamp 25 between the arms of which the bar 26 of the machine treadle 5 is adapted to be secured by taking upon set screws 27.

It will be noted that the connecting rod 2a consists of two overlapping parts clamped rigidly together by clamp 28. Thus said connecting rod is adjustable in length so that when the machine treadle is up, said rod can be adjusted to the proper operative length to reach the link 23 on the sleeve 20 when said sleeve is in its uppermost position,

whereby depressing the machine treadle carries the sleeve with it to retract the push member 12 to uncover the washer opening from the magazine and releasing the treadle causes the raising of said sleeve with the consequent result that the spring-pressed pivot arm 18 forces the push member forward and carries the topmost washer into operative position over the anvil. W hereupon again depressing the treadle causes said washer over the anvil to be riveted due to the descent of the machine head at at the same time that the push member is retracted to permit the up springing of another washer intothe feed-way and its subsequent delivery to the anvil upon the return of the treadle into elevated position. In other words, every release of the treadle in the machine shown causes a feeding of a washer to the anvil, whereas every down-press of the treadle causes the washer so fed to be taken up and permits another washer to spring up into position, ready to be fed to the anvil upon the release of the treadle.

Means for removably securing the attachment tothe machine is. shown comprising a clamp 29 on the magazine tube and adapted to engage afixed part of the machine, for example its post 30. It will be noted that the clamp can be loosened up to permit the axial turning of the magazine tube. There is considerable advantage in this, also in the fact that the head of the attachment is small because in box-work, which this attachment lends itself with particular advantage, it often happens as for example in setting rivets in the bottoms of suit-cases, bags, and so forth, that a rivet must be set in a corner which could not be reached even with the present attachment were it not arranged to permit turning to meet the given condition. \Vhen the clamp 29 is released and the magazine tube is turned, it will be noted that the attachment in the particular form shown swings about set-opening engaging stud 7 so that the anvil or place to which the washer or other part is fed by the attachment is not removed out of alinement with the machine head.

Preferably the sleeve 20 is mounted on the magazine tube to slide in fixed relation thereto as for example by making said tube of octagonal or other angular peripheral cross-section to which the inside of: the sleeve conforms.

Having thus described my invention, what I claim is:

l. A washer and the like feeding attachment for use in connection with setting machines, said attachment comprising a tubular magazine holding the washers in a pile, means yieldingly pressing the washers from below to deliver them from the mouth of the magazine, a head to which the magazine is attached having a washer guide-way into the bottom of which the ma azine mouth opens, an anvil in the bottom of said guide-way adapted when the a 'taclnnent is on the machine to be under the machine head, a push member working in the washer guide-way adapted on its return reciprocation to uncover the magazine opening to permit a washer to be tip-pressed into the guide-way and on its for 21rd reciprocation to feed said washer to the anvil, a downwardly extending projection on the head of the attachment located under the anvil and adapted to be lodged in the set-opening of the machine, means adapted to reciprocate the push member including an operative connection adapted to be made with the machine treadle, and means adapted to secure the attachment to the machine comprising a clamp on the magazine.
