STUD-SETTING MACHINE.

Application filed July 6, 1912.

To all whom it may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Stud-Setting lfachines, of which the followingdescription, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for setting lacing studs or hooks in sheet material such as the uppers of boots and shoes, and has for its object to improve machines of this class and render them capable of operation in a more convenient and satisfactory manner than formerly. I

In stud setting machines of this class the studs are placed in bulk in a reservoir from which they are fed successively to a position in line between the setting dies so that when the setting dies are forced toward each other the stud is clenched in the work. The work is then advanced for a distance equal to the spacing between successive studs and another stud inserted. One object of the invention is to provide a machine in which the work may be fed in either direction relatively to the setting dies. This in practice has been found to be advantageous in that, if for example studs are to be set in the left quarter of a shoe upper commencing from the lowermost point and feeding the work from right to left, then in setting studs in a right quarter it is possible to begin also at the lowermost point and feed the work from left to right. In using a machine where the work must be fed always in the same direction it has been necessary to begin at the lowermost point in one quarter and the uppermost point in the other quarter and this has caused undue delay and a considerable amount of variation in the position of the lowermost stud in the two quarters of the upper. The present invention, therefore, contemplates a machine for setting lacing studs or the like having, in combination, setting dies relatively movable toward one another to effect the setting operation, and means for positioning the stud for the setting operation so constructed and arranged as to permit the work to be fed with the clenched stud either from left to right or from right to left.

As herein shown, one means for positioning the stud comprises three guiding or po- Specification of Letters Patent.

sitioning members so arranged that as a stud is moved between the dies it will come into contact with the three members. Subsequently one of these members is moved relatively to the others so that the work, together with the clenched stud, can be fed either in the direction along which the stud was moved into position between the dies or in a direction opposite thereto.

Preferably the positioning member which is moved relatively to the other two comprises a stop which projects when one of the setting dies is retracted into the path of the stud located between the other two positioning members. The stop is mounted upon a stationary part of the machine and is left behind when the die and the other two positioning members are moved to effect the setting operation, so that the clenched stud is free to be moved in the direction in which it was formerly prevented from being moved by the stop.

Preferably one of the setting dies is provided with a part which is moved relatively thereto after a stud has been received so as to hold the stud in correct position. As herein shown the movable part is provided with a pair of cooperating guides or flanges which register with the raceway and receive a stud therefrom when the two are brought into register.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,

Figure 1 is a view in front elevation of the lower part of the machine with certain parts in section;

Fig. 2 is a similar view to Fig. 1 with other parts in section and showing a different stage in the operation of the machine;

Figs. 3 and 4 are respectively plan and sectional views of the gage mechanism, and

Fig. 5 is a view in side elevation of the lower part of the setting spindle.

The machine comprises a setting die 2 forming a part of the reciprocatory spindle 4, a raceway 6 down which the studs pass by gravity and an anvil or upsetting die 8 which cooperates with the die 2 to clench the barrel of a stud upon the lower side of the work.

The spindle 4 of the setting die is mounted to slide in vertical bearings, one of which is shown at 10, in a part of the frame 12 of the machine, and is actuated through suit able connections from a treadle, not shown. A spring 14 is provided to return the spindle 4 to its raised position, resting at one end upon the stationary bearing 10 and at the other bearing against a collar secured upon :the spindle of the setting die. The lower part of the spindle 4 which constitutes the setting die is concaved or recessed, as at 3, to form a seat for the head of the stud during the setting operation.

At its lower end the spindle 4 is partially surrounded by a sleeve 18 having a portion cut away at the side adjacent to the raceway 6. The sleeve 18, for a purpose hereinafter explained, is capable of a slight amount of sliding movement lengthwise of the spindle 4 and is attached to the end of the spindle by springs 20 which tend to draw its lower end into contact with the lower end of the spindle. Each of the springs 20 is attached at its lower end to a pin 22 projecting from the sleeve and at its upper end to a pin 24 fixed in the spindle. A slot 25 is provided in-each side of the sleeve to permit the latter to move downwardly in relation to the spindle and in opposition to the springs. When the spindle is moved upwardly and before it reaches its initial position, the upperendof the sleeve 18 encounters the lower end of the bearing 10, the springs20 permitting lost motion to occur between the sleeve and the spindle.

Secured to or formed as part of-the end of the sleeve 18 are the guide members or flanges 26 as shown in Fig. 5. These flanges form a continuation of the raceway 6 when the spindle 4 is in its raised position and so are adapted to engage the neck of a stud as it is delivered from the raceway. To maintain the lowermost stud which has passed from the raceway in a. central position beneath the setting die 2 a stationary stop 28 is provided which projects slightly below the die when the spindle 4 is in its elevated position. This stop also acts to prevent the stud delivered to the die from being pushed out through the sleeve by the weight of the studs remaining in the raceway.

In a preferred construction the stop 28 is formed of yielding material and is attached by a screw 29 to the upper part of the bearing 10. The spindle 4 is provided with a longitudinal slot to receive the stop 28. A. set screw 34is threaded into the bearing 10 and engages the stop 28 at its inner end so that the latter may be adjusted laterally relatively to the spindle in order to insure the proper positioning of the stud in relation to the setting die.

The raceway 6 is located on one side of the spindle 4 and is disposed in a substantially vertical position so that the studs supplied to it from any suitable reservoir sion will gravitate down the raceway to the setting die. The lower end of the raceway is curved in a vertical plane so as to deliver the studs beneath the end of the spindle 4 in substantially upright position, the spindle being cut away at one side to accommodate the end of the raceway.

The anvil or upsetting die 8 against which the end of the stud barrel is clenched by the action of the setting die 2 is located below the latter and .directly in alinement with it. The upsetting die may be shaped to correspond with the particular style of stud to be set and is provided with a projecting portion or nipple at the center upon which the barrel of each stud is forced during the setting operation.

The machine is provided with a pairof pointed spacing gages 36 and 38 arranged one on each side of the upsetting die and at equal distances from it. These gages constitute means whereby both left and right quarters of a shoe may be located so as to have the studs set in them atequaldistances apart beginning from either the uppermost or the lowermost stud according to .the requirements of the work in hand. The distance of the gages 36 and 38 from the .up-

setting die may be varied forithe purpose of altering the spacing of the studs and :the

arrangement is such that the symmetrical disposition of .the gages is maintained .inall their adjusted positions. For this purpose the'gages are pivoted at 39 to a carrier which .in this instance comprises .a slide 40 of triangular cross section as shown in Fig. 1. The slide 40 is adjustably mounted in an undercut slideway formed in .an exten- 13 ofthe frame. Adjustment .of the gages 36 and 3.8 is effected by .a screw 42 having a milled head for the convenience of the operator and right and left threaded portions, each threaded into a nut in one of the gages. The screw is provided with a collar 44- at its center whichengages in a groove in the slide 40 and so prevents longitudinal movement of the screw.

The front end of the slide 40 forms an edge gage 46 for guiding the work in the stud setting operation and determining the distance in from the edge of the work at which the stud is to be set. By adjusting the position of the slide 40 the position of the edge gage is varied and for this purposea screw 48 is threaded into a bore in the rear end of the slide 40 and is connected to the Xtension 13 of the frame by collars in such a manner as to be free for rotation but prevented from longitudinal movement. As the spacing gages 86 and 38 are pivoted upon the edge gage-slide 40 it follows that when the edge gage isadjusted rearwardly or forwardly'to vary the distance from the edge of the work at which the studs are to be inserted the points of the spacing gages 36 and 38 are correspondingly moved so that they are always against the edge of the work notwithstanding its position with relation to the setting dies.

The operation of the machine will doubtless be apparent from the foregoing description of its parts but for the sake of clearness a brief description of what occurs in the actual use of the machine will be given.

Assuming the spindle a to be held in its raised position through the action of the spring 1% a stud will then be delivered from the raceway 6 to the guide flanges 26. On account of the lost motion connection between'the sleeve 18 and the Spindle 4 the setting die 2 will occupy a position at a sufiicient distance above the flanges 26 to afford space for the head of a stud to pass freely beneath it, while the flanges themselves are held in alinement with the raceway by the engagement of the upper edge of the sleeve 18 with the bearing 10 as shown in Fig. 1. The stud received upon the guide flanges 26 moves into contact with the adjustable stop 28 by which it is located centrally beneath the die 2.

The work is placed between the die 2 and the upsetting die 8 and the treadle operated to cause the descent of the spindle 1. During the initial part of the descent of the spindle i the setting die 2 engages the head of the stud, the stud being thereafter held in position by the action of the springs 20 upon the sleeve 18. It will be apparent that the stud is gripped in this manner before the spindle descends sufficiently to carry the stud out of contact with the stop 28.

The continued downward movement of the spindle a forces the barrel of the stud through the material and over the nipple of the upsetting die and effects the setting operation. The spindle i is then allowed torise sufficiently to lift the clenched stud clear of the nipple of the upsetting die so that the stud can be moved laterally from beneath the die 2 along the guide flanges 26 in either direction lengthwise of the line in which the studs are being inserted. A uniform spacing between the studs is secured by moving the material to bringeach successive stud into register with one or the other of the spacing gages 36 or 38 according to the direction in which the work is fed, and then setting the neXt stud with the material so positioned.

The machine herein shown has been described as being treadle operated but it will be apparent that it could be equally well operated by power. It should be noted also that the machine may be adapted for handling studs of different types from the studs herein shown and that the use of the machine is not limited to any particular type of stud and that many features of the invention may be embodied in machines for setting other types of studs, rivets, eyelets, or similar articles.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A machine of the class described having, in combination, relatively movable stud setting devices, one of which is provided with a pair of cooperating flanges maintained permanently in spaced relation and arranged to engage a stud at opposite sides to support the stud during the entire setting operation while. leaving the stud free to be moved transversely in either direction after the setting operation, and having a recess shaped to fit the head of a stud with respect to which recess the flanges are movable to clamp or release a stud.

2. A machine of the class described having, in combination, relatively movable stud setting devices, one of which has a transversely extending opening to permit the free passage of the head of a stud, a recess to receive the head of a stud, and cooperating oppositely disposed projections maintained permanently in spaced relation, arranged to engage the head of the stud and support the stud during the entire setting operation, and being movable away from the recess to free a stud after the setting operation.
